Abstract

The present disclosure provides a locating pin, a working platform and a locating method. The locating pin includes a housing, a movable mechanism, a securing mechanism and a guide rod, wherein the housing has a first cavity with an opening that has an axis therethrough, the movable mechanism is at least partially arranged in the first cavity and configured to be movable along the axis, the securing mechanism is secured with respect to the housing and configured to limit movement of the movable mechanism along the axis, the guide rod includes a guide rod body and configured to extend out of the first cavity through the opening with the movement of the movable mechanism, the guide rod body having a first end and a second end opposite to each other, wherein the first end is secured to the movable mechanism, and the second end includes a locating portion.

First claim

What is claimed is:

1. A locating pin, comprising:
a housing, comprising a first cavity having an opening, wherein the opening has an axis therethrough;
a movable mechanism, at least partially arranged in the first cavity and configured to be movable along the axis;
a securing mechanism, secured with respect to the housing and configured to limit movement of the movable mechanism along the axis; and
a guide rod, comprising a guide rod body and configured to extend out of the first cavity through the opening with the movement of the movable mechanism, the guide rod body having a first end and a second end opposite to each other, wherein the first end is secured to the movable mechanism, and the second end comprises a locating portion;
wherein the securing mechanism is arranged at one end of the first cavity and comprises a second cavity, the locating portion is configured to pass through the second cavity so as to extend out of the first cavity, an end of the second cavity facing the movable mechanism comprises a guiding portion, and an end of the movable mechanism facing the second cavity comprises a boss that has an inclined side surface and matches the guiding portion.

2. The locating pin according to claim 1 , wherein the locating portion comprises a contact plane configured to be in contact with a to-be-located object.

3. The locating pin according to claim 2 , wherein a first angle formed between the contact plane and the axis is greater than 0 and less than 90 degrees.

4. The locating pin according to claim 1 , wherein a cross-sectional size of the locating portion is less than that of the guide rod body.

5. The locating pin according to claim 1 , wherein a portion of the locating portion connected with the guide rod body serves as a limiting portion that is configured to limit a maximum distance of the guide rod extending out of the first cavity.

6. The locating pin according to claim 1 , wherein a cross-sectional size of the guiding portion gradually increases towards the movable mechanism, and a cross-sectional size of the boss decreases gradually towards the securing mechanism.

7. The locating pin according to claim 6 , wherein a minimum cross-sectional size of the guiding portion is equal to a minimum cross section cross-sectional size of the boss.

8. The locating pin according to claim 1 , further comprising a driving mechanism configured to drive the movable mechanism to move along the axis.

9. The locating pin according to claim 8 , wherein the driving mechanism is arranged in the first cavity and around the movable mechanism, the driving mechanism comprises a spool mechanism and an electromagnetic coil wound on the spool mechanism, and the electromagnetic coil is configured to generate a magnetic force to drive the movable mechanism to move along the axis.

10. The locating pin according to claim 1 , wherein the securing mechanism is arranged at the opening, and wherein the movable mechanism is arranged within the first cavity and at one side of the first cavity opposite to the securing mechanism.

11. The locating pin according to claim 1 , further comprising a resetting member configured to urge the movable mechanism in a direction away from the securing mechanism.

12. A working platform, comprising
a supporting table, having a supporting surface and configured to bear thereon a to-be-processed object;
a locating hole, arranged in the supporting table; and
a locating pin, comprising a housing, a movable mechanism, a securing mechanism and a guide rod;
wherein the housing is provided with a first cavity having an opening that has an axis therethrough; the movable mechanism is at least partially arranged in the first cavity and configured to be movable along the axis; the securing mechanism is secured with respect to the housing and configured to limit movement of the movable mechanism along the axis; the guide rod comprises a guide rod body that has a first end and a second end opposite to each other, and is configured to extend out of the first cavity through the opening with the movement of the movable mechanism; the first end is secured to the movable mechanism; and the second end comprises a locating portion that is capable of passing through the locating hole and extending out of the supporting surface to assist in locating an to-be-processed object supported on the supporting surface, or capable of being retracted underneath the supporting surface along the locating hole;
wherein the securing mechanism is arranged at one end of the first cavity and comprises a second cavity, the locating portion is configured to pass through the second cavity so as to extend out of the first cavity, an end of the second cavity facing the movable mechanism comprises a guiding portion, and an end of the movable mechanism facing the second cavity comprises a boss that has an inclined side surface and matches the guiding portion.

13. The working platform according to claim 12 , wherein the locating portion comprises a contact plane configured to be in contact with the to-be-processed object.

14. The working platform according to claim 13 , wherein a first angle is formed between the contact plane and the axis, a second angle is formed between the axis and a side surface of the to-be-processed object and equal to the first angle, the supporting table further comprises a side wall intersecting the supporting surface, the locating hole extends to the side wall from the supporting surface, a third angle is formed between an extension direction of the locating hole and a direction perpendicular to the supporting surface and is equal to the first angle, and the first angle is greater than 0 and less than 90 degrees.

15. The working platform according to claim 12 , wherein a maximum height of the locating portion extending out of the supporting surface is greater than 9 mm.

16. The working platform according to claim 12 , wherein a portion of the locating portion connected with the guide rod body serves as a limiting portion that is configured to limit a maximum distance of the guide rod extending out of the first cavity.

17. The working platform according to claim 12 , wherein a cross-sectional size of the locating portion is less than that of the guide rod body, and wherein a cross-sectional size of the locating hole is greater than and equal to that of the locating portion and less than that of the guide rod body.
