The fixture includes a first mounting plate 1, a second mounting plate 2 and a watch case fixing device, so as to realize quick clamping of the watch case 5, have high working efficiency, and are not easy to affect the processing accuracy and processing quality.

[0026] like Figure 1 to Figure 5As shown, multiple watch cases 5 are fixed to the upper end face of the first mounting plate 1, and multiple first circular through holes 103 matching the elliptical holes 501 are provided on the first mounting plate 1. The second mounting plate 2 is fixedly connected to the lower end face of the first mounting plate 1, and the second mounting plate 2 is provided with second circular through holes 201 matching the multiple first circular through holes 103. The watch case fixing device is fixedly connected to the bottom end face of the second mounting plate 2, and the watch case fixing device is clamped to the inner end face of the elliptical hole 501 of the watch case 5, so that the watch case 5 is fixed by the watch case fixing device.

[0027] The first mounting plate 1 is fixed on the processing workbench.

[0028] The watch case fixing device includes a plurality of positioning blocks 101, a plurality of positioning columns 102, a rotating downward pressing cylinder 3 and an elliptical pressing head assembly 4. The elliptical pressing head assembly 4 matches the elliptical hole 501 on the watch case 5, and the elliptical pressing head assembly 4 abuts against the inner wall end surface of the elliptical hole 501 of the watch case 5.

[0029] The end surfaces of the first mounting plate 1 that are in contact with the watch case 5 are fixedly connected to a plurality of positioning blocks 101 that match the watch case 5, and the plurality of positioning blocks 101 are fixedly connected to positioning columns 102 that match the positioning holes 502, and the positioning columns 102 pass through the positioning holes 502, that is, when the watch case 5 is fixed on the elliptical pressure head assembly 4, the plurality of positioning columns 102 clamp onto the inner wall end surfaces of the positioning holes 502 of the watch case 5 to support and fix them.

[0030] Furthermore, multiple positioning blocks 101 are located at a pair of opposite end faces of the multiple first circular through holes 103, that is, a pair of opposite end faces of the first circular through holes 103 are welded with multiple positioning blocks 101, and the positioning blocks 101 abut against the bottom end face of the watch case 5 to enhance the stability of the watch case 5 when it is fixed.

[0031] like Figure 3 to Figure 5 As shown, the elliptical pressing head assembly 4 includes an elliptical pressing head 401, a first limiting column 402 and a second limiting column 403. The elliptical pressing head 401 matches the elliptical hole 501. The elliptical pressing head 401 is clamped on the inner wall end face of the elliptical hole 501 of the watch case 5 to fix it.

[0032] The bottom end surface of the elliptical pressure head 401 is fixedly connected to the first limiting column 402, and the bottom end surface of the first limiting column 402 is fixedly connected to the second limiting column 403. The diameter of the second limiting column 403 is smaller than the diameter of the first limiting column 402, and the projection of the elliptical pressure head 401 on the horizontal plane is larger than the projection of the first limiting column 402 on the horizontal plane.

[0033] The elliptical pressing head assembly 4 passes through the second circular through hole 201 and the first circular through hole 103. When in use, the elliptical pressing head assembly 4 passes through the second circular through hole 201 and the first circular through hole 103, so that the elliptical pressing head 401 is clamped on the inner wall end face of the elliptical hole 501 of the case 5 for fixation.

The rotary pressing cylinder 3 is fixed to the bottom end surface of the elliptical pressing head assembly 4. The elliptical pressing head 401 is controlled to move downward by the rotary pressing cylinder 3, and rotated 90 degrees to press the end surfaces of both sides of the positioning hole 502 of the watch case 5 for fixing.

[0035] It should be noted here that the rotary downward pressing cylinder 3 is located on the lower end surface of the multiple first circular through holes 103 of the first mounting plate 1, and its position matches the position of the elliptical hole 501 on the watch case 5, so that the multiple rotary downward pressing cylinders 3 can quickly clamp the multiple watch cases 5 through the multiple elliptical pressing head assemblies 4 connected above.

[0036] It should be noted that the rotary downward pressure cylinder 3 includes a cylinder and a piston, and is a pneumatic actuator that uses compressed air to drive the output to perform reciprocating rotation within a certain angle range, and is used for the rotation, pulling, flipping, sorting, feeding, opening and closing of doors, and robot arm movements. The installation method and power supply connection method of the rotary downward pressure cylinder 3 are both common knowledge in the field and will not be repeated here.

The second threaded holes 202 and the first threaded holes 104 are threadedly connected with first bolts to fix the first mounting plate 1 and the second mounting plate 2.

[0038] When using, Figure 2 As shown, during clamping, the watch case 5 passes through the elliptical pressing head 401 through the elliptical hole 501. At this time, after the positioning hole 502 is aligned with the positioning column 102 on the positioning block 101 and installed and clamped, the rotating downward pressing cylinder 3 is started to control the elliptical pressing head assembly 4 to move downward and rotate 90 degrees to press the two sides of the short sides of the end faces of the watch case 5 on both sides of the positioning hole 502 to fix it.
