[0002] Cam refers to a mechanical rotating or sliding part (such as a wheel or a protrusion of a wheel) that transmits motion to a roller moving close to its edge or a needle bar moving freely on a groove surface, or it receives force from such rollers and needle bars. The cam follower mechanism can be designed to meet almost any input-output relationship within its range of motion. For some purposes, a cam stop plate assembly is required to stop the cam in the four-wheel drive coupling, and a cam groove grinding device for the cam stop plate assembly is required to grind the cam groove on the cam stop plate assembly.

[0003] In the prior art, when the existing cam groove grinding device of the cam stop plate assembly is used, since the cam groove of the cam stop plate assembly is provided with multiple cam grooves, when grinding the multiple cam grooves, after one of the cam grooves is ground, it is necessary to manually change the position of the cam stop plate assembly to continue grinding the remaining cam grooves. In this way, when changing the grinding position of the cam groove, a lot of time is wasted, the grinding speed is slow, and the grinding efficiency is low. Moreover, it is inconvenient to add grinding liquid to the grinding position during grinding, which affects the grinding quality of the product. In addition, the grinding debris is easy to splash into the eyes of personnel from the top of the grinding, causing safety hazards and low safety. Now, a cam groove grinding device of the cam stop plate assembly is urgently needed to solve the above problems. Utility Model Content

Then, the driving motor 131 in the driving assembly 13 is operated to drive the driving gear 132 to rotate, the driving gear 132 rotates to drive the connecting gear 133 to rotate, the connecting gear 133 rotates to drive the rotating column 12 to rotate, the rotating column 12 rotates to drive the fixed plate 11 to rotate, and the fixed plate 11 rotates to drive the cam stop plate assembly 9 placed on the positioning plate 10 to rotate so that the cam groove 91 thereon is rotated to the appropriate position, that is, the grinding head 81. Directly below, the driving motor 131 stops working, and then the pressing electric push rod 51 in the pressing assembly 5 is operated to drive the suspension seat 52 on its telescopic shaft to move downward, and the suspension seat 52 at the bottom of the mounting seat 6 is driven downward by the action of the spring 53. The downward movement of the suspension seat 52 drives the mounting seat 6 to rotate around the rotating shaft 7 along the rotating groove 41, thereby driving the mounting seat 6 to move downward, and the downward movement of the mounting seat 6 drives the grinding head 81 on the working electric grinder 8 to move downward to press and grind the cam groove 91 on the cam stop plate assembly 9. The grinding head 81 on the electric grinder 8 moves downward and allows the spring 53 to always maintain a constant pressure on the electric grinder 8 to grind the cam groove 91 on the product cam stop plate assembly 9, simulating hand-pressed grinding, improving the stability of grinding, and thus improving the quality of grinding.

[0041] When the cam groove 91 is polished and the remaining cam grooves 91 to be polished need to be replaced, the pressing electric push rod 51 in the pressing assembly 5 is operated to drive the suspension seat 52 on its telescopic shaft to move upward, and the spring 53 drives the suspension seat 52 at the bottom of the mounting seat 6 to move upward. The upward movement of the suspension seat 52 drives the mounting seat 6 to rotate around the rotating shaft 7 along the rotating groove 41, thereby driving the mounting seat 6 to move upward. The upward movement of the mounting seat 6 drives the grinding head 81 of the electric grinder 8 on the mounting seat 6 to move upward, so that the grinding head 81 is separated from the cam groove 91 to reach the avoidance position The driving motor 131 in the driving assembly 13 is then operated to drive the driving gear 132 to rotate, the driving gear 132 rotates to drive the connecting gear 133 to rotate, the connecting gear 133 rotates to drive the rotating column 12 to rotate, the rotating column 12 rotates to drive the fixed plate 11 to rotate, the fixed plate 11 rotates to drive the cam stop plate assembly 9 placed on the positioning plate 10 to rotate so that the cam groove 91 to be polished thereon is rotated to a suitable position, that is, directly below the grinding head 81, the replacement of the cam groove 91 to be polished is completed, and the grinding head 81 is connected to the output shaft of the electric grinder 8.

[0042] When the cam groove 91 to be polished is completed, the pressing component 5 drives the grinding head 81 of the electric grinder 8 on the mounting seat 6 to move downward to polish the replaced cam groove 91, avoiding the need to manually change the position of the cam stop plate assembly 9 to continue to grind the remaining cam grooves 91, thereby saving replacement time, increasing the grinding speed of the cam groove 91, and improving the grinding efficiency of the cam groove 91. Since the pressing component 5 is symmetrically arranged with a pair of grinding heads 81 thereon and respectively drives the grinding heads 81 thereon to grind the symmetrically arranged cam grooves 91 at the same time, the two opposite cam grooves 91 are polished on both sides at the same time, saving grinding time, thereby further improving the grinding efficiency.

[0043] The grinding liquid storage cylinder 16 and the guide tube 161 are used to deliver the grinding liquid to the grinding connection between the grinding head 81 and the cam groove 91, and the flow of the grinding liquid is controlled by a valve, thereby facilitating the addition of grinding liquid to the grinding point and improving the grinding quality.
