The adjacent sides of the opening of the control board are set to be one long and one short. The short side of the control board is provided with the pressing plate, and the long side of the control board is provided with the lifting plate.
[0011] Further, in the embodiment of the present invention, the pressing plate moves up and down along the control board, and the moving plate moves left and right along the pressing plate.

When the moving plate moves outward, the clamping plate follows and moves outward, and the clamping plate is inserted into the groove of the limit plate to fix the limit plate, and then the rotating motor connected to the main body drives the conversion device and the auxiliary device to rotate as a whole, and the limit plate is kept squeezed on the clamping plate by the cooperation of the limit rod and the auxiliary rail, so that the clamping plate is kept fixed to the connecting rod, and after rotating a certain angle, the connecting rod inside the placement plate is turned over to complete the surface burr polishing again;
[0019] After double-sided grinding is completed, the jacking device drives the connecting rod to move downward, and stops moving after the bottom plate of the jacking device moves to be flush with the conveyor belt surface of the second frame. At this time, the pushing device moves to the left to push the connecting rod out of the upper surface of the bottom plate into the top of the conveyor belt of the second frame for unloading.
[0020] The beneficial effects of the present invention are:
[0021] The grinding device for connecting rod processing of the present invention moves to the top of the auxiliary device through the guide plate when surface grinding is performed on the connecting rod, and lifts up the connecting rod through the jacking device coordinated with the auxiliary device so as to fit with the grinding head of the grinding device for surface grinding, and does not require manual grinding to ensure grinding accuracy. After the grinding is completed, for burrs on the other side of the connecting rod, the jacking device is lowered to place the connecting rod in the through hole of the placement plate, and then the grinding device is lowered so that the clamping plate clamps the surface of the connecting rod, and the moving plate and the lifting plate clamp the placement plate at the same time, and then the conversion device is rotated as a whole through an external rotating motor to rotate and flip the connecting rod. After flipping, the connecting rod is lifted up again by the jacking device to fit with the grinding head of the grinding device for grinding burrs. In this way, the turning over of the connecting rod does not require manual control to prevent hand injuries caused by manual turning over, and can also prevent the position from shifting after manual turning over, resulting in inconsistent grinding accuracy.

[0053] The control board 303 is set in a "mouth" shape with an opening. The adjacent sides at the opening of the control board 303 are set to be one long and one short. The short side of the control board 303 is provided with the pressing plate 304, and the long side of the control board 303 is provided with the lifting plate 306.

By fixing the auxiliary device 40 with the conversion device, the auxiliary device 40 can follow the rotation of the conversion device during rotation, thereby driving the internal connecting rod 50 to turn over. During the turning-over process, the auxiliary device 40 holds the connecting rod 50 to prevent the connecting rod 50 from falling inside and unable to be turned over and polished.
[0055] As Figure 5 、 6As shown, the auxiliary device 40 includes: a placing plate 401, a clamping plate 402, a limiting plate 403, and a clamping plate 404. The placing plate 401 is arranged below the grinding device 20, and the placing plate 401 is adaptably connected to the conversion device; the clamping plate 402 is arranged inside the placing plate 401, and the clamping plate 402 is movably connected to the placing plate 401; the limiting plate 403 is arranged inside the placing plate 401, and the limiting plate 403 is located on the left side of the clamping plate 402, and the limiting plate 403 is movably connected to the placing plate 401; the clamping plate 404 is arranged inside the placing plate 401, and the clamping plate 404 is located on the left side of the limiting plate 403, and the clamping plate 404 is movably connected to the placing plate 401, and the clamping plate 404 is used to fix the limiting plate 403.

The outer circumference of the bottom plate 602 is smaller than the size of the through hole on the surface of the placement plate 401. The bottom plate 602 extends into the through hole of the placement plate 401 through the lifting motor 601.

After the burrs on one side of the connecting rod 50 are ground, the grinding device 20 moves downward, the lifting device 60 moves downward to place the connecting rod 50 in the through hole of the placement plate 401, and then the grinding device 20 applies force to the limit plate 403 to push the clamping plate 402 outward to clamp the surface of the connecting rod 50. After the connecting rod 50 is clamped, the moving plate 305 drives the control plate 303 to be pushed outward through the lifting plate 306 to clamp the placement plate 401, and then the conversion device rotates as a whole through the external rotating motor to drive the placement plate 401 and the connecting rod 50 inside the placement plate 401 to rotate and turn over, and the burrs on the other surface of the connecting rod 50 are ground, so as to achieve accurate grinding of the burrs on both sides of the connecting rod 50 to prevent different grinding accuracies.

The arc surface of the clamping plate 402 fits the surface of the connecting rod 50 for clamping. The movable plate 305 and the lifting plate 306 clamp the placement plate 401. At the same time, the rotation motor outside the main body 302 drives the rotation so that the T-shaped end of the limit rod 307 rotates along the auxiliary track 3081 of the inner shell 308. During the rotation of the placement plate 401, the clamping plate 402 keeps clamping the connecting rod 50 to turn over the connecting rod 50. Through the cooperation of the clamping plate 404, the limiting plate 403 and the movable plate 305, the clamping plate 402 can always keep the connecting rod 50 fixed during the turning process of the connecting rod 50, and the connecting rod 50 will not fall off during the rotation and become unable to be turned over. During the turning process, the lifting plate 306 is fixed by the limiting rod 307 to prevent the lifting plate 306 from loosening during the rotation.

[0063] The connecting rod 50 is placed horizontally on the surface of the conveyor belt 104 of the first frame 101, and the connecting rod 50 is conveyed to the guide plate 105 by the conveyor belt 104, so that the connecting rod 50 automatically slides down through the downwardly inclined edge through the guide plate 105 and moves to the top of the auxiliary device 40;
[0064] After the connecting rod 50 reaches above the auxiliary device 40, the connecting rod 50 falls into the inside of the placing plate 401 through the through hole opened on the surface of the placing plate 401. At this time, the connecting rod 50 is pushed upward by the lifting motor 601 of the lifting device 60, and the grinding device 20 moves downward at the same time. After the grinding device 20 moves downward to a certain distance, the lower surface of the grinding device 20 contacts the limit plate 403, and the clamping plate 402 is made to approach the connecting rod 50 through the limit plate 403 to clamp and fix the connecting rod 50, and then the grinding device 20 continues to move downward to grind the burrs on the surface of the connecting rod 50;
