[0003] A Chinese patent with the application number 2023232069132 discloses a bushing polishing device for automobile part processing, including a base. A set of support seats are fixedly installed on the left and right lower parts of the base respectively. The two sets of support seats are symmetrically distributed left and right and each set has two. A set of support columns are fixedly installed on the left and right upper parts of the base respectively. The two sets of support columns are symmetrically distributed left and right and each set has two. A cross plate is fixedly installed on the upper ends of the two sets of support columns. A second hydraulic cylinder is fixedly installed in the middle of the upper end of the cross plate.

Detailed implementation manner

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] As Figures 1-5 shown, the present invention is an automobile part processing device, including a bottom plate 1 and a bushing 13; two vertical plates 12 are provided on the bottom plate 1; a support assembly 2 is provided on one of the vertical plates 12 for the preliminary fixation of the bushing 13, and a fixing assembly 3 is provided on the other vertical plate 12 for the fixation of the bushing 13.

[0026] In this embodiment, the support assembly 2 includes a motor 21, a baffle 22, a first rotating shaft 23, a first spring telescopic rod 24 and a first support plate 25; a motor 21 is installed on one of the vertical plates 12, the output end of the motor 21 extends through the vertical plate 12 and is provided with a baffle 22, a first rotating shaft 23 is provided on the baffle 22, at least two first spring telescopic rods 24 are provided on the outer ring surface of the first rotating shaft 23, and the upper ends of the first spring telescopic rods 24 are respectively provided with first support plates 25;

[0027] The support assembly 2 further includes an arc plate 26, arc plates 26 are respectively provided at the ends of the first support plates 25 away from the baffle 22, and the ends of the arc plates 26 away from the first support plates 25 are bent inward;

[0028] The diameter of the circle formed by the three first support plates 25 is greater than the diameter of the bushing 13, and the diameter of the opposite ends of the arc-shaped plate 26 is less than the diameter of the bushing 13;

[0029] First, one end of the bushing 13 is sleeved on the shaped plate 26. Subsequently, the bushing 13 is pushed upward along the vertical direction. During the upward push, the bushing 13 starts to compress the first spring telescopic rod 24 located below it. Due to the elastic characteristics of the first spring telescopic rod 24, while being compressed, it will exert an equal and opposite reaction force on the bushing 13, and this reaction force cancels out the force pushing the bushing 13, thus achieving a dynamic equilibrium state. In this way, the bushing 13 is firmly fixed on the first support plate 25, completing its preliminary fixation and providing a stable foundation for subsequent fixation.

[0030] In this embodiment, the fixing assembly 3 includes a cylinder 31, a second rotating shaft 33, a supporting circular plate 34, a second support plate 341, a rotating cap 35, an inclined plate 351, a support block 36, a second spring telescopic rod 37, a clamping plate 38, a connecting plate 381 and a third spring telescopic rod 382; a cylinder 31 is installed on another vertical plate 12, and the output end of the cylinder 31 is rotatably provided with a second rotating shaft 33. The second rotating shaft 33 penetrates through the supporting circular plate 34 and is connected to the support block 36. The circular plate 34 is slidably connected to the second rotating shaft 33; the lower end of the circular plate 34 is connected to the bottom plate 1 through the second support plate 341; at least two second spring telescopic rods 37 are hinged on the support block 36, and the other end of the second spring telescopic rod 37 is hinged to the clamping plate 38. A connecting plate 381 is provided on the clamping plate 38, and a third spring telescopic rod 382 is hinged between the connecting plate 381 and the circular plate 34; an inclined plate 351 cooperating with the clamping plate 38 is provided on the second rotating shaft 33;

[0031] Through the expansion and contraction of the cylinder 31, the three clamping plates 38 are driven to move forward and move into the interior of the port of the bushing 13, and at the same time, the third spring telescopic rod 382 is stretched. When the third spring telescopic rod 382 is pulled, the third spring telescopic rod 382 gives a reaction pulling force to the connecting plate 381 and the clamping plate 38, causing the clamping plate 38 to move backward. While the clamping plate 38 moves backward, the inclined plate 351 continues to move forward with the expansion and contraction of the cylinder. Since the clamping plate 38 is in contact with the inclined plate 351 at the beginning, during the process of the inclined plate 351 continuing to move forward, it pushes the clamping plate 38 to move upward, so that the clamping plate 38 contacts the inner wall of the bushing 13 and completes the fixation of the bushing 13;

[0032] After the clamping plate 38 is in full contact with the inner wall of the bushing 13, the fixing of the bushing 13 is completed. The internal fixing method ensures that the entire outer surface of the bushing 13 is exposed without any obstruction. In this way, the external polishing machine can complete the polishing treatment of the entire outer surface of the bushing 13 at one time, without multiple adjustments or repeated operations, improving the polishing efficiency and processing quality.

[0033] Preferably, a threaded portion 32 is provided on the second rotating shaft 33, and a rotating cap 35 is screwed onto the threaded portion 32. The opposite ends of the inclined plate 351 are connected to the rotating cap 35. By rotating the rotating cap 35, the three inclined plates 351 move forward, thereby pushing the three clamping plates 38 to expand outward synchronously, increasing the diameter of the circle formed by the three clamping plates 38, so as to be used for bushings 13 of different sizes.

[0034] Preferably, the center line of the first rotating shaft 23 and the center line of the support block 36 are on the same horizontal line.

[0035] The surfaces of the first support plate 25 and the clamping plate 38 in contact with the bushing 13 are arc-shaped to facilitate fitting with the inner ring surface of the bushing 13.

[0036] A chute 11 is formed in the bottom plate 1, and a sliding rod 4 is slidably arranged inside the chute 11. The upper end of the sliding rod 4 is connected to the second rotating shaft 33 to form a support for the second rotating shaft 33.

[0037] The diameter of the baffle 22 is larger than the diameter of the bushing 13 to prevent one end of the bushing 13 from abutting against the vertical plate 12.

[0038] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
