[0009] Furthermore, slots are provided on both sides of the connecting platform.
[0010] Furthermore, a connecting pipe is fixedly installed on the bottom side of the flexible clamp, and the connecting pipe is slidably connected to the through hole.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This utility model, through the combination of a fan and a through hole, can collect the dust generated during the grinding of automotive parts by drawing it into the main housing, preventing the dust from flying in the air and being inhaled by workers, thus preventing them from being harmed. This enriches the product's functionality and increases its safety during use.
[0013] 2. This utility model, through the cooperation of connecting pipe and through hole, can conveniently connect the flexible fixture to the connecting table, thereby enabling flexible adjustment of the position of the flexible fixture according to the shape and size of automotive parts, increasing the applicability of the product.

[0023] Example:
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides a positioning fixture for grinding automotive parts, including a main housing 1. A connecting platform 2 is installed on the top side of the main housing 1. Multiple sets of flexible clamps 3 are installed on the top side of the connecting platform 2. Multiple sets of through holes 4 are provided at equal intervals on the connecting platform 2. A fixing frame 6 is fixedly installed on the inner side of the main housing 1. A filter plate 7 is connected to the top side of the fixing frame 6. A fan 8 is installed on the bottom side of the filter plate 7 on the inner side of the main housing 1. The input end of the fan 8 is set corresponding to the filter plate 7.
[0026] The base 9 is fixedly installed on the bottom side of the main housing 1 by fasteners. The top side of the base 9 is fixedly connected to the fan 8 by fasteners. The base 9 is provided with multiple exhaust ports 10 corresponding to the fan 8, which can stably fix the fan 8 inside the main housing 1.
[0027] The connecting platform 2 is fixedly installed on the bottom side of the connecting seat 5. The outer side of the connecting seat 5 is slidably connected to the inner side of the main housing 1, so that the connecting platform 2 can be conveniently placed on the main housing 1.
[0028] Two sets of handles 12 are symmetrically fixed on the top side of the filter plate 7, which can be used to easily replace the filter plate 7.
[0029] A sealing ring 13 is fixedly bonded to the bottom side of the connecting seat 5. The bottom side of the sealing ring 13 abuts against the top side of the filter plate 7 to prevent dust from escaping to the outside through the junction of the connecting seat 5 and the filter plate 7.
[0030] The connecting platform 2 has slots 14 on both sides, which allows for convenient movement of the connecting platform 2.
[0031] The flexible clamp 3 is fixedly installed with a connecting pipe 11 on its bottom side. The connecting pipe 11 is slidably connected to the through hole 4, which can facilitate the connection of the flexible clamp 3 to the connecting platform 2 and allow for flexible adjustment of the position of the flexible clamp 3. Both the connecting pipe 11 and the through hole 4 are square to ensure that the flexible clamp 3 will not rotate after connection, thus ensuring stability during use.
[0032] The working principle of this embodiment is as follows: When it is necessary to polish automotive parts, the blower 8 in the product is connected to an external power supply and control unit. The position of the flexible clamp 3 is selected according to the size and shape of the automotive parts, and multiple sets of flexible clamps 3 are connected to the connecting platform 2 through the connecting pipe 11. Then, the automotive parts are fixed on the connecting platform 2 through the multiple sets of flexible clamps 3. The blower 8 is started, and the automotive parts are polished by the polishing equipment. At this time, the blower 8 draws the dust generated by polishing into the main housing 1 through the through hole 4 and collects it through the filter plate 7. The filtered air is discharged from the main housing 1 through the blower 8 and the exhaust port 10. After polishing is completed, the blower 8 is turned off, and the polishing operation is completed.
[0033] Finally, it should be noted that the flexible clamp 3 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art and are common knowledge in the field, so they will not be described in detail.
