[0018] The positioning module further eliminates residual displacement deviation on the basis of the adjustable pushing path through the cooperation of the bidirectional roller clamping mechanism and the return spring. When the V-shaped base is pushed to the polishing wheel, the two rollers form a dynamic clamping force field under the pre-tightening force of the return spring, which allows the base to move smoothly in the pushing direction and inhibits the small deviation perpendicular to the pushing direction through frictional resistance. Especially for the asymmetric angle base, the adaptive rotating characteristics of the rollers can automatically match the side profile of the base, and cooperate with the polishing wheel spacing adjustment mechanism to build a double-stable mechanism of "path adjustable + posture locking", thereby improving the polishing uniformity.

[0019] The polishing assembly adopts a sliding slide plate structure. The driven polishing wheel can move up and down along the slide plate on the support. The spacing between the driven polishing wheel and the driven polishing wheel is steplessly adjusted. The driven polishing wheel can always maintain stable extrusion force on the base of different height televisions through the elastic support of the buffer spring seat and the top plate. The driven gear belt wheel is driven by the connecting rod. The transmission stability is maintained through the automatic compensation mechanism of the gear belt tension. This design makes the device compatible with the polishing requirements of various specifications of television base, without frequent replacement of tooling, and greatly improves the production flexibility.

[0020] The device integrates a tension spring and a telescopic spring in the push plate reset mechanism and the polishing wheel transmission system respectively to form a two-stage buffer structure. When the push plate is reset, the tension spring provides controllable pullback force to avoid mechanical impact. In the transmission system, the telescopic spring absorbs the vibration generated by the displacement of the driven polishing wheel through elastic deformation to ensure that the gear belt transmission is always in the best tension state. The two groups of springs work together to effectively suppress the shaking and noise during the operation of the device and prolong the service life of the key components.

[0038] Further, as shown in FIG. 4, Figure 1 , Figure 5 , Figure 7As shown, the upper end side of the workbench 1 is provided with a pushing module, the pushing module is used for pushing the sliding plate 15 to slide on the variable guide block 19, the pushing module comprises two bearing seats 28, the two bearing seats 28 are clamped and rotationally connected with a screw rod 29, the upper end of one side bearing seat 28 is provided with a second servo motor 30, the output end of the second servo motor 30 is fixedly connected with the screw rod 29, the outer portion of the screw rod 29 is drivingly connected with a sliding seat 27, the lower end of the sliding seat 27 is slidingly connected with the workbench 1, the side close to the sliding plate 15 of the sliding seat 27 is fixedly connected with a push rod 26, the middle part of the one side end surface of the sliding plate 15 is fixedly connected with an arc block 37, the outer wall middle part of the arc block 37 is the same height as the axis of the push rod 26, the upper end of the one side end surface of the sliding plate 15 close to the support 3 is fixedly connected with a push block 36, the side close to the support 3 of the push block 36 is recessed inward, the inner side wall of the side close to the fixed groove block 20 of the variable guide block 19 is fixedly connected with a tension spring 21, the end away from the fixed groove block 20 of the tension spring 21 is fixedly connected with the sliding plate 15;

[0040] Further, as Figure 5As shown, the upper end of the workbench 1 is provided with an adjusting module away from the side of the pushing module, the adjusting module is used for adjusting the deformation amount of the variable guide block 19, the adjusting module comprises a supporting seat 16 fixedly connected to the upper end face of the workbench 1, a threaded rod 17 threadedly connected to the upper end of the supporting seat 16, a turntable fixedly connected to one end of the threaded rod 17, an extrusion plate 18 fixedly connected to the upper end of one side of the movable slot block 22, one end of the threaded rod 17 away from the turntable in contact with the extrusion plate 18, a fixed seat 25 fixedly connected to one end of the sliding slot 23 on the workbench 1, a pull-back spring 24 fixedly connected to one side end face of the fixed seat 25, and one end of the pull-back spring 24 away from the fixed seat 25 is fixedly connected with the movable slot block 22;

[0045] When the polished TV base is pushed above the support module, the support block 11 first contacts the bottom of the base, and as the base continuously moves, the support block 11 transmits the pressure to the connecting spring 38 in the first sleeve rod 9 through the first sliding rod 10, the connecting spring 38 is elastically deformed after being pressed, so that the first sliding rod 10 slides downward along the inner wall of the first sleeve rod 9, and the height of the support block 11 is automatically adjusted to adapt to the bottom profile of the base, and at the same time, the rebound force of the spring always upwardly lifts the base, forming a flexible support effect, which can effectively absorb the slight position deviation or gravity sagging trend of the base after polishing, so that the base remains in a horizontal stable state after completely leaving the polishing area, avoids the inclination, sliding or surface damage of the base due to insufficient support, and provides a reliable workpiece positioning basis for subsequent processes.
