Abstract

A sliding mechanism includes a case, a sliding assembly mounted in the case and a stopping assembly. The sliding assembly includes a sliding member and a driving member supplying power for the sliding member. The stopping assembly includes a resisting portion mounted in the case, two first sliders and a pushing portion positioned on the resisting portion, and two first elastic portions. The resisting portion includes two slant surfaces. The first elastic portions resist the first sliders and the resisting portion. The first sliders are driven by the pushing portion to move along the slant surfaces of the resisting portion and away from the resisting portion, thereof compressing the first elastic portions. The first sliders are driven by the elastic forces of the first elastic portions to move along the slant surfaces and toward the sliding member, thereof clamping the sliding member.

First claim

What is claimed is:

a sliding member; and
a driving member supplying power for the sliding member; and

a stopping assembly fixed in the case and comprising:
a resisting portion comprising two slant surfaces;
two first sliders positioned on the resisting portion;
a pushing portion positioned on the resisting portion; and
two first elastic portions resisting the first sliders and the resisting portion;

wherein the resisting portion, the two first sliders, the a pushing portion and the elastic portions are positioned in the case; the first sliders are configured for sliding on the resisting portion; and
wherein, the first sliders, when driven by the pushing portion, move along the slant surfaces of the resisting portion and away from the resisting portion, thus compressing the first elastic portions; and the first sliders, when driven by the elastic forces of the first elastic portions, move along the slant surfaces and toward the sliding member, thus clamping the sliding member.

2. The sliding mechanism of claim 1 , wherein the resisting portion further comprises a holding groove and a first bump received in the holding groove, the pushing portion is received in the holding groove and can slide in the holding groove.

3. The sliding mechanism of claim 2 , wherein the first bump comprises two resisting surfaces, each first slider comprises a first surface and a second surface, the two first sliders are received in the holding groove, the first surfaces of the two first sliders are attached on the resisting surfaces of the first bump; and the second surfaces of the two first sliders are attached on the slant surfaces of the resisting portion.

4. The sliding mechanism of claim 3 , wherein the stopping assembly further comprises a second slider, a first groove is defined on the resisting portion, the first groove is interconnected to the holding groove, the second slider is held in the first groove.

5. The sliding mechanism of claim 4 , wherein the pushing portion is positioned close to the two first sliders, the second slider is connected to the two first elastic portions, when the second slider driven by the elastic forces of the first elastic portions to slide in the first groove, the two first sliders are driven by the second slider to move close to each other, thus clamping the sliding member.

6. The sliding mechanism of claim 3 , wherein the stopping assembly further comprises a housing, the housing comprises a base and a lid fixed on the base, the base is fixed in the case, a cavity is defined on the base, the resisting portion is received in the cavity, when the pushing portion is driven toward the first bump, the resisting portion slides away from the pushing portion in the portion cavity.

7. The sliding mechanism of claim 6 , wherein two sliding shots are defined on the lid, the top ends of the two first sliders protrude through the two sliding shots.

8. The sliding mechanism of claim 6 , wherein the stopping assembly further comprises a second elastic portion, one end of the second elastic portion resists against the resisting portion and the other end of the second elastic portion resists against the base, when resisting portion slides away from the pushing portion, the second elastic portion is compressed.

9. The sliding mechanism of claim 4 , wherein the resisting portion further comprises a supporting plate, a second bump and a fixing part; the first bump, the second bump and the fixing part are formed on the supporting plate.

10. The sliding mechanism of claim 9 , wherein the second bump and the fixing part are located at edges of the supporting plate, the first bump is located between the second bump and the fixing part, the first bump is separated from the second bump and the fixing part.

11. The sliding mechanism of claim 10 , wherein the first bump, the second bump and the fixing part extend away from a top surface of the supporting plate upwards and perpendicularly, top surfaces of the first bump, the second bump and the fixing part are coplanar.

12. The sliding mechanism of claim 10 , wherein an opening is defined on the supporting plate, the opening penetrates a top and bottom surfaces of the supporting plate, and the opening is located between the fixing part and the first bump.

13. The sliding mechanism of claim 9 , wherein the second bump comprises a bottom surface and the two slant surfaces, the two slant surfaces are slant to the bottom surface, the bottom surface faces the first bump, and a distance between the two slant surfaces increases gradually away from the bottom surface.

14. The sliding mechanism of claim 13 , wherein the bottom surface, the slant surfaces and the supporting plate together define the holding groove, a second groove is defined on the bottom surface, the second groove is interconnected to the holding groove, and the pushing portion protrudes through the second groove.

15. The sliding mechanism of claim 2 , wherein the sliding assembly further comprises four sliding rails and two draw slips, the sliding rails are fixed in the case, the draw slips are positioned on the sliding rails, and the sliding member is fixed on the draw slips.

16. The sliding mechanism of claim 15 , wherein an extending part is formed on the sliding member, the two first sliders are located at two opposite sides of the extending part, and the extending part is clamped by the two first sliders under elastic forces of the first elastic portions.

17. The sliding mechanism of claim 15 , wherein the driving member comprises a stator and an active cell, the active cell and stator are separated from each other with a presupposed distance therebetween.

18. A machining device, comprising:
a sliding mechanism comprising:
