[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figures 1-5 This utility model provides a snap ring installation position gauge, including an annular detection plate 1. The top of the annular detection plate 1 is connected to a positioning component 2, and the bottom of the annular detection plate 1 is connected to a snap ring detection component 3. The positioning component 2 includes a positioning plate 201, and a positioning hole 202 is opened at the center of the top of the positioning plate 201 for insertion with the spline guide post of the dual clutch drive disc. The snap ring detection component 3 includes at least one snap ring detection plate 301, and the bottom end of the snap ring detection plate 301 is machined with an arc-shaped groove 302.

[0026] The number of snap ring detection plates 301 is set to three, and the three snap ring detection plates 301 are arranged in a ring array at the bottom of the ring detection plate 1 to detect whether the snap ring installation position is accurate.

[0027] To facilitate the rotation of the annular detection plate 1 by the staff, a hand-held part is connected to the top of the positioning plate 201. Specifically, the hand-held part includes a handle 4, which is detachably connected to the positioning plate 201. By grasping the handle 4, the staff can rotate the annular detection plate 1 more conveniently.

[0028] In use, the operator first grasps handle 4 and places the positioning plate 201 onto the spline guide post of the dual clutch drive disc. The positioning hole 202 must match the size of the drive disc spline guide post to ensure that the positioning plate 201 perfectly fits the drive disc spline guide post, thus detecting the position of the annular detection plate 1. Then, the three snap ring detection plates 301 are secured to the inside of the snap rings on the dual clutch. Manually rotating handle 4 causes the annular detection plate 1 to rotate together. If the snap rings are in place, there will be no jamming when rotating the annular detection plate 1. If there is jamming when rotating the annular detection plate 1, it indicates that the snap rings are not installed correctly and have protruding parts. At this time, the operator can re-secure the snap rings to ensure that they are installed correctly. This embodiment integrates positioning and snap ring detection functions on the annular detection plate 1, which can ensure both the accuracy of the placement of the annular detection plate 1 and the reliability of the snap ring installation, thus improving quality control.

[0029] Refer to the instruction manual appendix Figures 1-5 Each snap ring detection plate 301 has an arc-shaped insert plate 303 fixedly installed at its top. The bottom of the inner wall of the annular detection plate 1 has an arc-shaped slot 304 with the same number of arc-shaped insert plates 303. The arc-shaped insert plates 303 are inserted into the arc-shaped slots 304, and the arc-shaped insert plates 303 and the annular detection plate 1 are detachably connected by bolts.

[0030] The annular detection plate 1 has positioning grooves 7 on both sides of its top. The two ends of the positioning plate 201 are respectively inserted into the two positioning grooves 7. The bottom two sides of the positioning plate 201 are fixed with arc-shaped plates 8. The outer wall of the arc-shaped plates 8 contacts the inner wall of the annular detection plate 1, which can improve the stability of the positioning plate 201.

[0031] Spring pins 9 are fixedly inserted through both outer walls of the annular detection plate 1. The two arc-shaped plates 8 are provided with insertion holes 10 on the opposite side to the spring pins 9. The pin head of the spring pin 9 passes through the annular detection plate 1 and is inserted into the insertion hole 10, which facilitates the quick assembly and disassembly of the positioning plate 201 by the staff.

[0032] By loosening the bolts on the arc-shaped insert plate 303, the arc-shaped insert plate 303 and the snap ring detection plate 301 can be removed from the annular detection plate 1 together, which facilitates the disassembly and cleaning of the snap ring detection plate 301. Since the arc-shaped plate 8 and the annular detection plate 1 are connected by the spring pin 9, pulling the spring pin 9 will move the pin head on the spring pin 9 out of the slot, and the positioning plate 201 can be removed from the annular detection plate 1 by grasping the handle 4. This also facilitates the cleaning and replacement of the positioning plate 201. When installing the positioning plate 201, simply align the two ends of the positioning plate 201 with the positioning groove 7 and insert it, and then loosen the spring pin 9. The structure is simple, and the installation and disassembly of the positioning plate 201 and the snap ring detection plate 301 are very quick.

[0033] Each arc-shaped insert plate 303 is fixedly provided with at least one locking block 5 on the side near the arc-shaped slot 304. The inner wall of each arc-shaped slot 304 is machined with the same number of slots 6 as the locking blocks 5. The locking blocks 5 and the slots 6 are engaged. By engaging the locking blocks 5 and the slots 6, the firmness between the arc-shaped insert plate 303 and the annular detection plate 1 can be further improved.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
