Abstract

A positioning device includes a fixing mechanism, a first positioning assembly, a second positioning assembly. The fixing mechanism includes a base, a first moving member movably passing through the base, and a second moving member movably passing through the base. The first positioning assembly includes a bottom board and two first guide portions protruding from the bottom board. Each first guide portion forms one first incline surface. The second positioning assembly includes a base body and two second guide portions. The base body is positioned between the two first guide portions respectively positioned on opposite side surfaces of the base body. Each second guide portion forms a guiding surface. The first moving member is fixed with the bottom board at one end away from the base. The second moving member is fixed with the base body at one end away from the base.

First claim

What is claimed is:

1. A positioning device configured for positioning a workpiece, the workpiece comprising a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, the first sidewall, the second sidewall, the third sidewall, and the fourth sidewall cooperatively forming a positioning hole, the first sidewall being opposite to the third sidewall, the second sidewall being opposite to the fourth sidewall, the positioning device comprising:
a fixing mechanism comprising:
a base;
a first moving assembly comprising a first moving member, a first elastic member, the first moving member movably passing through the base, and the first elastic member sleeved on the first moving member; and
a second moving assemblies comprising a second moving member and a second elastic member, the second moving member movably passing through the base, and the second elastic member sleeved on the second moving member;
a first positioning assembly mounted on the fixing mechanism, the first positioning assembly comprising a bottom board and two first guide portions separately protruding from the bottom board, each first guide portion forming one first incline surface, one first incline surface configured for resisting against the first sidewall, and another one first incline surface configured for resisting against the third sidewall; and
a second positioning assembly positioned above bottom board away from the base, the second positioning assembly comprising a base body and two second guide portions, the base body positioned between the two first guide portions, the two second guide portions respectively positioned on opposite side surfaces of the base body, each second guide portion comprising a guiding surface, one guiding surface configured for resisting against the second sidewall, and another one second guiding surface configured for resisting agonist the fourth sidewall,
wherein the first moving member is fixed with the bottom board at one end away from the base, the first elastic member is resisted between the base and the bottom board;
the second moving member is fixed with the base body at one end away from the base, the second elastic member is resisted between the base and the base body;
the first guide portions are configured for stretching into the positioning hole to enable one first incline surface resist against the first sidewall and another one first incline surface resisting against the third sidewall, such that motions of the workpiece along a direction substantially parallel to the second sidewall is limited; the second sidewall resiliently cooperates with one guiding surface, and the fourth sidewall resiliently cooperates with another guiding surface, thereby imposing a limiting resistance to motion of the workpiece along a direction substantially parallel to the first sidewall.

2. The positioning device of claim 1 , wherein an angle formed between the first incline surface and the bottom board is greater than or equal to about 75 degrees, an angle formed between each guiding surface and the base body is less than or equal to about 15 degrees.

3. The positioning device of claim 1 , wherein the first positioning assembly further comprises a first mounting member, the first moving member passes through the first mounting member each first elastic member resists the first moving member; the second positioning assembly further comprises a second mounting member, the second moving member resists against the second mounting member.

4. The positioning device of claim 1 , wherein the first guide portion further comprises a first surface and a vertical surface, the first surface is substantially parallel to the bottom board, the vertical surface is substantially perpendicularly coupled to the first surface and opposed to the first incline surface, a first joint edge is formed between the vertical surface and the first surface, a second joint edge is formed between the incline surface and the first surface.

5. The positioning device of claim 4 , wherein the base body comprises two end surfaces, a second surface, a third surface, and a fourth surface, each end surface is opposite to one vertical surface, the second surface is substantially parallel to and away from the second mounting member, the second surface is coupled between the third surface and the fourth surface, a third joint edge is formed between each end surface and the second surface, the third joint edges is parallel to the first joint edge, a length of each third joint edge is greater than lengths of the first joint edge and the second joint edge, two separate fifth through holes are defined in the base body.

6. The positioning device of claim 1 , wherein the base comprises a seat, the seat comprises a main body and two extending portions extending from the main body, the first moving member passes through the main body.

7. The positioning device of claim 6 , wherein the first moving assembly further comprises a first snap ring, the first snap ring is clamped with an end of the first moving member away from the first elastic member.

8. The positioning device of claim 6 , wherein the second moving assembly further comprises a second snap ring clamped with an end of the first moving member away from the first elastic member.

9. The positioning device of claim 6 , wherein the base further comprises at least two guiding members, the at least two guiding members are received in the seat, the first moving member passes through one of the at least two guiding members, and the second moving member passes through another one of the at least two guiding members.

10. The positioning device of claim 1 , wherein the two first guide portions are made of plastic steel.

11. A positioning device comprising:
a fixing mechanism, comprising:
a base;
a first moving member movably passing through the base; and
a second moving member movably passing through the base;
a first positioning assembly comprising a bottom board and two first guide portions separately protruding from the bottom board, each first guide portion forming one first incline surface; and
a second positioning assembly positioned above bottom board away from the base, the second positioning assembly comprising a base body and two second guide portions, the base body positioned between the two first guide portions, the two second guide portions respectively positioned on opposite side surfaces of the base body, each second guide portion comprising a guiding surface,
wherein the first moving member is fixed with the bottom board at one end away from the base; and
wherein the second moving member is fixed with the base body at one end away from the base.

12. The positioning device of claim 11 , wherein an angle formed between the first incline surface and the bottom board is greater than or equal to about 75 degrees, an angle formed between each guiding surface and the base body is less than or equal to about 15 degrees.

13. The positioning device of claim 11 , wherein the fixing mechanism further comprises a first mounting member and a second mounting member, the first moving member passes through the first mounting member, each first elastic member resists the first moving member, and the second moving member resist against the second mounting member.
