DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] like Figures 1 to 4 A positioning device for polishing automobile parts is shown, comprising a workbench 1. Four supporting legs can be installed on the bottom surface of the workbench 1 to facilitate raising the height of the workbench 1. The top surface of the workbench 1 can be externally connected to an existing polishing mechanism, and it only needs to be able to polish automobile parts. Vertical blocks 2 are symmetrically installed on the top surface of the workbench 1. Two vertical blocks 2 are rotatably connected to opposite sides with bidirectional threaded rods 3. The surface of the bidirectional threaded rods 3 is processed with two threads in opposite directions. A driving motor 15 is fixedly installed on one side of one of the vertical blocks 2. The output shaft of the driving motor 15 passes through the vertical block 2 and is fixedly connected to one end of the bidirectional threaded rod 3. The driving motor 15 can drive the bidirectional threaded rod 3 to rotate between the two vertical blocks 2.

[0027] Two movable blocks 4 are symmetrically sleeved on the circumference of the bidirectional threaded rod 3. When the bidirectional threaded rod 3 rotates, the two movable blocks 4 will be driven to move in relative or opposite directions. The opposite side of the two vertical blocks 2 and the lower part of the bidirectional threaded rod 3 are fixedly connected to the limiting rod 16. The two movable blocks 4 are both slidably sleeved on the circumference of the limiting rod 16. When the two movable blocks 4 move, they will also move on the circumference of the limiting rod 16, so that the limiting rod 16 restricts the two movable blocks 4 to ensure that the two movable blocks 4 can only move laterally along the bidirectional threaded rod 3.

[0028] The top surfaces of the two movable blocks 4 are fixedly installed with vertical plates 5, and the two vertical plates 5 are respectively installed on the opposite sides of the top surfaces of the two movable blocks 4. The opposite sides of the two vertical plates 5 are fixedly connected with pin shafts 6, and the free ends of the two pin shafts 6 are rotatably connected with round blocks 7. The two round blocks 7 can be rotated on the opposite sides of the two vertical plates 5 through the two pin shafts 6 respectively. An arc block 8 is fixedly installed on one side of the top surfaces of the two movable blocks 4. The sizes of the two arc blocks 8 are larger than the sizes of the two round blocks 7. The arc block 8 can limit the rotation of the round block 7 and can also limit the round block 7. The two arc blocks 8 are provided with circular grooves 9 adapted to the round blocks 7 on the side facing the round blocks 7. The two round blocks 7 are arranged in the inner cavity of the circular grooves 9. The opposite sides of the two round blocks 7 are installed with placement plates 10 for placing automobile accessories. The length of the placement plate 10 is less than the diameter of the round block 7. When it is necessary to grind the automobile accessories, turn on the drive motor 15 to drive the bidirectional threaded rod 3 to rotate, thereby driving the two When the two movable blocks 4 are moved in relative or opposite directions, the two movable blocks 4 can drive the two round blocks 7 to move through the vertical plate 5 and the pin 6, and the two round blocks 7 can respectively drive the two placement plates 10 to move, so that the distance between the two placement plates 10 can be adapted to automobile accessories of different lengths, thereby facilitating the fixing of the automobile accessories on the top surface of the placement plates 10. When the automobile accessories need to be polished or turned over for polishing at different angles, one of the round blocks 7 is rotated so that the round block 7 can be rotated through the pin 6. Since the automobile accessories are fixed on the top surfaces of the two placement plates 10, when one of the round blocks 7 is rotated, the other round block 7 can be driven to rotate through the fixed automobile accessories, so that the two round blocks 7 can respectively rotate in the inner cavities of the two circular grooves 9, which can drive the fixed automobile accessories to rotate, making it convenient to polish or turn over the automobile accessories at different angles, avoiding the need to constantly adjust the polishing angle or disassemble and assemble for turning over and polishing, and improving the efficiency of polishing automobile accessories.

[0029] Threaded holes 11 are provided on the circumferential side of the round block 7 and the top surface of the arc block 8. The inner cavities of the two threaded holes 11 aligned with the side surface of the round block 7 and the top surface of the arc block 8 are threadedly connected with a first bolt 12. When the round block 7 needs to be rotated, the first bolt 12 is taken out from the two aligned threaded holes 11 to cancel the fixation of the round block 7. At this time, the round block 7 can be rotated to adjust the angle of the auto part. After adjusting the angle, the first bolt 12 is inserted into the two aligned threaded holes 11, and the position of the round block 7 after the angle adjustment can be fixed by the self-locking of the thread, so as to fix the auto part.

[0030] One side of the top surface of the two placement plates 10 is threadedly connected with a second bolt 13, and the circumferential side of the two second bolts 13 is threadedly connected with a pressure block 14 for fixing the automobile accessories. The two second bolts 13 are respectively arranged on the top surface of the two placement plates 10 and on the opposite side, and one side of the two pressure blocks 14 is in friction contact with one side of the round block 7. After the automobile accessories are placed on the placement plate 10, the second bolts 13 are rotated so that the second bolts 13 drive the pressure blocks 14 to move downward and squeeze the automobile accessories, so that the automobile accessories can be fixed between the placement plate 10 and the pressure blocks 14, so that the automobile accessories can rotate and subsequently grind with the round block 7.

[0031] Working principle:

[0032] The positioning device for polishing automobile parts, when the automobile parts need to be polished, the driving motor 15 is turned on, and the driving motor 15 drives the two movable blocks 4 to move in relative or opposite directions through the bidirectional threaded rod 3, so that the two movable blocks 4 drive the round blocks 7 to move through the vertical plate 5 and the pin 6, so that the two round blocks 7 drive the two placement plates 10 to move, and the distance between the two placement plates 10 is adapted to the size of the automobile parts to be polished. At this time, the automobile parts are fixed on the top surface of the placement plates 10 through the second bolts 13 and the pressing blocks 14, and the polishing process can be carried out. When the polishing angle or When turning over and grinding, rotate the first bolt 12 to remove the first bolt 12 from the two threaded holes 11, and the fixation of the round block 7 can be cancelled. At this time, rotating the round block 7 can drive the placement plate 10 to rotate, thereby driving the automobile accessories to rotate, and then conveniently adjusting to a suitable grinding angle or turning over and grinding. After adjusting to a suitable angle, insert the first bolt 12 into the two aligned threaded holes 11 to fix the position of the round block 7, so as to perform the grinding process, avoiding the need to constantly adjust the grinding angle of the automobile accessories and the turning over of the automobile accessories, thereby improving the efficiency of grinding the automobile accessories.
