[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model has the following specific embodiments.

[0026] Example:

[0027] A clamp for polishing rubber seals includes a processing table 1, one end of the top of the processing table 1 is fixedly connected to a support frame 11, the top of the support frame 11 is penetrated by a hydraulic cylinder 12, the rear side of the support frame 11 is fixedly connected to a controller 13, and also includes a clamping mechanism and a polishing mechanism, the clamping mechanism includes a polishing positioning seat 2, a hanging seat 3 and an L-shaped rotating frame 4, a positioning groove 21 is provided on the top of the polishing positioning seat 2, a servo motor 32 is fixedly connected to the top of the hanging seat 3, the output shaft of the servo motor 32 is fixedly connected to one end of the L-shaped rotating frame 4, the bottom of the L-shaped rotating frame 4 is fixedly connected to two hanging rods 42, a conical extrusion roller 421 is rotatably connected to the hanging rod 42, and the polishing mechanism includes a rotating column 5, one end of the rotating column 5 is movably connected to a buffer rod 52, and one end of the buffer rod 52 is fixedly connected to a polishing wheel 521.

[0028] By adopting the above technical solution, when using the device, the rubber seal to be processed is first placed in the positioning groove 21, and then the hydraulic cylinder 12 is opened to drive the hanger 3 to descend. The hanger 3 can push the connected L-shaped rotating frame 4 to descend, so that the L-shaped rotating frame 4 can push the two conical extrusion rollers 421 to squeeze on the rubber seal. At the same time, the grinding wheel 521 can flexibly fit on the rubber seal, and then the servo motor 32 is turned on to drive the L-shaped rotating frame 4 to rotate on the hanger 3. The rotating L-shaped rotating frame 4 can simultaneously drive the grinding wheel 521 to rotate, so that the rubber seal can be annularly extruded and polished, which can improve the processing efficiency of the rubber seal.

[0029] Specifically, the grinding wheel 521 is located between the two conical extrusion rollers 421 , and the conical extrusion rollers 421 roll along the annular path of the positioning groove 21 .

[0030] One end of the rotating column 5 passing through the L-shaped rotating frame 4 is fixedly connected to the second gear 51. The first gear 33 fixed inside the hanging seat 3 is meshed with the second gear 51, and the rotating column 5 rotates in conjunction with the L-shaped rotating frame 4.

[0031] The other end of the buffer rod 52 is fixedly connected to an extrusion block 522, and a limiting opening 53 is provided on the outer surface of the rotating column 5. The extrusion block 522 moves inside the rotating column 5, and the limiting rod 524 fixed on the extrusion block 522 slides in the limiting opening 53. The top of the extrusion block 522 is fixedly connected to a spring 523, and one end of the spring 523 is fixedly connected to the inside of the rotating column 5. The movable fixing knob 525 on the buffer rod 52 is threadedly engaged with the rotating column 5.

[0032] By adopting the above technical solution, the grinding wheel 521 can be flexibly fitted on the rubber seal for grinding. When the grinding wheel 521 is squeezed on the rubber seal, the grinding wheel 521 pushes the squeezing block 522 to slide upward in the rotating column 5 through the buffer rod 52, and squeezes the connected spring 523. The spring 523 is compressed and can generate a reaction force, so that the grinding wheel 521 can be flexibly fitted on the surface of the rubber seal for grinding. At the same time, the rotating L-shaped rotating frame 4 can automatically drive the rotating column 5 to drive the grinding wheel 521 to rotate, that is, when the L-shaped rotating frame 4 rotates on the hanger 3, the L-shaped rotating frame 4 can drive the rotating The column 5 rotates, and since the second gear 51 fixed on the rotating column 5 is meshed with the first gear 33 fixed inside the hanger 3, when the second gear 51 is installed, the rotating column 5 can rotate on the L-shaped rotating frame 4, and since the extrusion block 522 connected to the buffer rod 52 is inserted into the limit opening 53 through the limit rod 524, the rotating rotating column 5 can drive the buffer rod 52 to rotate, and then the buffer rod 52 drives the grinding wheel 521 to rotate, so that the conical extrusion roller 421 can be driven to perform annular extrusion on the rubber seal, and the grinding wheel 521 can perform annular displacement grinding on the rubber seal, which can improve the grinding efficiency.

[0033] Specifically, an annular sliding groove 31 is formed on the outer surface of the hanging seat 3 , and a sliding block 41 fixed at one end of the L-shaped rotating frame 4 slides inside the annular sliding groove 31 .

[0034] By adopting the above technical solution, the slider 41 can be rotated to slide in the annular sliding groove 31 provided on the hanging seat 3, thereby facilitating the limited rotation between the hanging seat 3 and the L-shaped rotating frame 4.

[0035] Specifically, the interior of the positioning groove 21 is provided with a frosted surface, a rubber seal is embedded and connected inside the positioning groove 21 , and the depth of the positioning groove 21 is less than the thickness of the rubber seal.

[0036] By adopting the above technical solution, the frosted surface set inside the positioning groove 21 can increase the friction, so that the rubber seal can be fixed after being pressed, and the rubber seal can be prevented from slipping during the grinding process. At the same time, the depth of the positioning groove 21 is less than the thickness of the rubber seal, which can make it protrude from the inside of the positioning groove 21, making it easier for the conical extrusion roller 421 to cooperate with the grinding positioning seat 2 to extrude the rubber seal.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification.
