Abstract

A fixing jig includes a support plate for supporting a workpiece. A fixing member is arranged on the support plate and defines a receiving groove penetrating a bottom surface of the fixing member. A stopper is slidably received in the receiving groove. A bottom surface of the stopper is flush with the bottom surface of the fixing member and contacts the support plate. An end of the stopper extends out of the receiving groove and abuts against the workpiece. The adjusting member is coupled to the fixing member. One end of the adjusting member extends into the receiving groove and is coupled to the stopper. The adjusting member is used to adjust a position of the stopper. The locking member is arranged on the adjusting member and used to lock a position of the adjusting member, thereby locking the position of the stopper.

First claim

What is claimed is:

1. A fixing jig comprising:
a support plate configured for supporting a workpiece;
a fixing member arranged on the support plate, the fixing member defining a receiving groove penetrating a bottom surface of the fixing member;
a stopper slidably received in the receiving groove, a bottom surface of the stopper being flush with the bottom surface of the fixing member and contacting the support plate, an end of the stopper extending out of the receiving groove to abut against the workpiece thereby positioning the workpiece in a horizontal direction;
an adjusting member coupled to the fixing member, one end of the adjusting member extending into the receiving groove and coupled to the stopper, and another end of the adjusting member arranged outside the receiving groove, the adjusting member being configured to adjust a position of the stopper; and
a locking member arranged on the adjusting member and configured to lock a position of the adjusting member, thereby locking the position of the stopper; wherein:
a cross-sectional area of the end of the stopper extending out of the receiving groove is less than a cross-sectional area of the end of the stopper received in the receiving groove;
the stopper comprises a main body and a pushing portion;
the main body is slidably received in the receiving groove, and the pushing portion is coupled to an end of the main body;
the pushing portion protrudes from the receiving groove;
a length of the main body is greater than a length of the pushing portion;
a width of the main body is the same as a width of the pushing portion; and
a cross-sectional area of the pushing portion is less than a cross-sectional area of the main body.

2. The fixing jig of claim 1 , wherein:
a bottom surface of the pushing portion is flush with a bottom surface of the main body; and
a top surface of the pushing portion is coupled to a top surface of the main body through an inclined surface.

3. The fixing jig of claim 2 , wherein:
a rounded edge is arranged between the inclined surface and the top surface of the pushing portion.

4. The fixing jig of claim 1 , wherein:
the cross-sectional shape of the main body is the same as a cross-sectional shape of the receiving groove.

5. The fixing jig of claim 1 , wherein:
a distance that the stopper extends from the receiving slot is within a range of 4-5.5 cm.

6. The fixing jig of claim 1 , further comprises a plurality of beams, wherein:
each of the plurality of beams is located above the support plate;
two ends of each beam are coupled to the support plate; and
the plurality of beams is configured to press the workpiece onto the support plate in a vertical direction.

7. A fixing jig comprising:
a support plate used for supporting a workpiece;
a fixing member arranged on the support plate, the fixing member defining a receiving groove penetrating a bottom surface of the fixing member;
a stopper slidably received in the receiving groove, a bottom surface of the stopper being flush with the bottom surface of the fixing member and contacting the support plate, an end of the stopper extending out of the receiving groove and being configured to abut against the workpiece;
an adjusting member coupled to the fixing member, one end of the adjusting member extending into the receiving groove and coupled to the stopper, and another end of the adjusting member arranged outside the receiving groove, the adjusting member being configured to adjust a position of the stopper;
a locking member arranged on the adjusting member and being configured to lock a position of the adjusting member, thereby locking the position of the stopper; and
a limiting block arranged on the support plate, the stopper arranged opposite to the limiting block, and the stopper and the limiting block cooperatively fixing the position of the workpiece in the horizontal direction;
the stopper comprises a main body and a pushing portion;
the main body is slidably received in the receiving groove, and the pushing portion is coupled to an end of the main body;
the pushing portion protrudes from the receiving groove;
a length of the main body is greater than a length of the pushing portion;
a width of the main body is the same as a width of the pushing portion; and
a cross-sectional area of the pushing portion is less than a cross-sectional area of the main body.

8. The fixing jig of claim 7 , wherein:
a bottom surface of the pushing portion is flush with a bottom surface of the main body; and
a top surface of the pushing portion is coupled to a top surface of the main body through an inclined surface.

9. The fixing jig of claim 8 , wherein:
a rounded edge is arranged between the inclined surface and the top surface of the pushing portion.

10. The fixing jig of claim 9 , wherein:
the cross-sectional shape of the main body is the same as a cross-sectional shape of the receiving groove.

11. The fixing jig of claim 10 , wherein:
a distance that the stopper extends from the receiving slot is within a range of 4-5.5 cm.

12. The fixing jig of claim 11 , further comprises a plurality of beams, wherein:
each of the plurality of beams is located above the support plate;
two ends of each beam are coupled to the support plate; and

the plurality of beams is configured to press the workpiece onto the support plate in a vertical direction.
