[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 2 and Figure 3 As shown, the main hub grinding equipment provided by the embodiment of the present application includes a frame, and also includes a rotating positioning mechanism arranged on the frame 1 for supporting the bottom of the main hub, a clamping mechanism 3 arranged on the frame 1 for pressing down the top of the main hub, and a plurality of grinding mechanisms 4 for grinding the main hub weld, the clamping mechanism 3 includes a No. 1 seat arranged on the frame 1, a rotary clamping cylinder 32 arranged on the No. 1 seat, a connecting shaft 33 arranged at the output end of the rotary clamping cylinder 32, a ball bearing 34 sleeved on the connecting shaft 33, and a pressure head assembly fixedly connected to the outer ring of the ball bearing 34, the pressure head assembly includes a flange 35 abutting against the upper end face of the outer ring of the ball bearing 34 and a cylindrical pressure head 31 fixedly connected to the flange, and the cylindrical pressure head 31 is provided with a step abutting against the lower end face and outer periphery of the outer ring of the ball bearing 34.

[0021] In actual use, the main rotating hub is placed on the rotating positioning mechanism, and the rotating positioning mechanism is used to support the main rotating hub. Then, the upper end of the main rotating hub is pressed by the pressing mechanism 3, and then the rotating positioning mechanism drives the main rotating hub to rotate.

[0022] The weld is ground by the grinding mechanism 4. The working principle of the clamping mechanism 3 is as follows: the connecting shaft 33 is driven downward by the rotating clamping cylinder 32, so that the cylindrical pressure head 31 presses the upper end of the main hub, and when the rotating positioning mechanism rotates to drive the product to rotate synchronously, due to the rotation performance of the ball bearing 34, the product drives the cylindrical pressure head 31 to rotate synchronously.

[0023] In the above design, the structural design of the grinding mechanism 4 can press the main hub and ensure that the main hub can rotate stably under the drive of the rotation positioning mechanism, so that the weld of the main hub can be quickly ground by the grinding mechanism 4 in a fixed position, thereby achieving efficient deburring of the weld of the main hub.

[0024] Specifically: Figure 3 As shown, the lower end of the cylindrical pressure head 31 is provided with a downwardly contracted conical guide portion.

[0025] It should be noted that a groove is provided on the upper end surface of the main rotating hub.

[0026] In the above design, the tapered guide portion can help the tapered guide portion extend into the groove on the upper end surface of the main hub.

[0027] Specifically: Figure 1 , Figure 3 and Figure 5 As shown, the grinding mechanism 4 includes a No. 1 grinding component 41 for grinding the weld from above and a No. 2 grinding component 42 for grinding the weld from below, the No. 1 grinding component 41 includes a No. 1 cylinder 411 vertically arranged on the frame 1 with the output end upward, a No. 1 connecting member 412 fixedly arranged at the output end of the No. 1 cylinder 411, and a No. 1 grinder 413 and a No. 2 grinder 414 arranged on the No. 1 connecting member 412, the No. 1 grinder 413 and the No. 2 grinder 414 are respectively used to grind different welds, the No. 2 grinding component 42 includes a No. 2 cylinder 421 vertically arranged on the frame 1 with the output end upward, a No. 2 connecting member 422 fixedly arranged at the output end of the No. 2 cylinder 421, and a No. 3 grinder 423 arranged on the No. 2 connecting member 422.

[0028] In actual use, the weld on the upper end face of the main hub is polished by the No. 1 polishing assembly 41, and the weld on the lower end face of the main hub is polished by the No. 2 polishing assembly 42. The polishing working principle is: the No. 1 cylinder 411 drives the No. 1 connecting member 412 to move downward, so that the No. 1 grinder 413 and the No. 2 grinder 414 act on the corresponding weld, and the No. 2 cylinder 421 drives the No. 2 connecting member 422 to move upward, so that the No. 3 grinder 423 acts on the corresponding weld.

[0029] In the above design, the structural design and specific implementation method of the grinding mechanism 4 can quickly grind the weld of the main hub.

[0030] Specifically: Figure 6As shown, the No. 1 connecting member 412 includes a No. 1 block 4121 arranged at the output end of the No. 1 cylinder 411, a No. 1 L-shaped block 4122 and a No. 2 L-shaped block 4123 connected to the No. 1 block 4121, a No. 1 clamp 4124 arranged on the No. 1 L-shaped block 4122 for connecting the No. 1 grinder 413, and a No. 2 clamp 4125 arranged on the No. 2 L-shaped block 4123 for connecting the No. 2 grinder 414, the No. 2 L-shaped block 4123 is provided with an arc groove 401, and the No. 2 clamp 4125 is provided with a screw hole matching the arc groove 401.

[0031] In actual use, the second clamp 4125 is rotated by adjusting the corresponding positions of the screw hole and the arc groove 401, thereby adjusting the angle of the second grinder 414.

[0032] In the above design, the structural design of the No. 1 connecting member 412 can adjust the angle of the No. 2 grinder 414 .

[0033] Specifically: Figure 1 As shown, a protective cover 6 is also provided on the frame 1 , and the protective cover 6 is provided with avoidance holes for avoiding the grinding mechanism 4 and the pressing mechanism 3 .

[0034] In actual use, when the grinding mechanism 4 grinds the weld, the burrs that are ground off will produce splashes, and the protective cover 6 can shield the splashes.

[0035] In the above design, the design of the protective cover 6 can shield the flying debris and effectively ensure the safety of the operator.

[0036] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
