Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a positioning fixture for automotive parts. Background Technology

[0002] Automotive parts can be defined narrowly or broadly. Broadly speaking, automotive parts, besides those commonly classified as parts in current production, also include key assemblies such as engine assemblies and transmission assemblies, certain related components, and cast and forged blanks. Additionally, while the car body is often listed separately in statistics, it is also considered a part in the broader sense.

[0003] Chinese patent application CN2023213151589 discloses a positioning fixture for automotive parts, comprising: When fixing the top of a part, the fixture uses a fixing component to press a vertical rod downwards. During this movement, a slot compresses a locking block, causing it to retract into the groove until the pressure plate is firmly attached to the part. The locking block engages with the slot for fixation. Compared to existing devices, this provides more stable fixation and prevents the part from shaking. When using the auxiliary component, because the surface of the part is uneven, the pressure plate cannot adhere to the part's surface. The fitting component ensures that when the pressure plate contacts the part, the housing is compressed, causing it to fit against the outer wall of the block. The combination of the block, the housing, and the second spring allows for contact with even uneven surfaces of the part, resulting in a larger contact area and better fixing effect.

[0004] The aforementioned patent cannot adjust the height of the base plate according to the height of the processing personnel, which is inconvenient for workers of different heights to process the parts on the base plate. At the same time, the original device has poor accuracy in limiting the block through the fixing components, and the block has poor effect in pressing and fixing the parts. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This utility model, by setting up a lifting component, rotates a two-way lead screw two in a fixed box. The rotation of the two-way lead screw two drives two sliding blocks to move towards each other in the fixed box. The two sliding blocks moving towards each other push the base plate to rise and fall through the rotating plate. The telescopic rod extends and retracts between the fixed box and the base plate. By setting up the lifting component, the base plate can be adjusted to different heights according to the height of the processing personnel, which is convenient for workers of different heights to process the parts on the base plate.

[0015] 2. This utility model, by setting a second screw, allows the clamping block to move to a suitable position and then rotate the shaft within the fixed plate. The rotation of the shaft drives the worm gear to rotate, and the worm gear drives the second screw to rotate on the horizontal plate via a worm gear. The rotation of the second screw causes the top plate to move downward, and the top plate, through the upright, causes the block to move downward. The downward movement of the block can press and fix the components. By setting a second screw, the accuracy of the block's lifting and lowering is improved, and the block's firmness in pressing the components is enhanced. Attached Figure Description

The lower end of the fixed box 21 is provided with the fixing assembly 27.

[0025] Specifically, the fixing component 27 includes an anti-slip pad 271, a fixing frame 272, a partition 273, a mounting plate 274, a mounting hole 275, and a screw 276. The fixing box 21 has an anti-slip pad 271 at its lower end, a fixing frame 272 at its lower rear end, a partition 273 in the middle of the fixing frame 272, and a screw 276 parallel to the rear surface of the fixing box 21. The screw 276 passes horizontally through the left and right sides of the fixing frame 272 and through the partition 273 in the center of the fixing frame 272. The mounting plate 274 is threaded onto the surface of the screw 276, and the mounting plate 274 has a mounting hole 275.

[0026] By adopting the above technical solution, rotating the screw 276 drives the mounting plate 274 to move in the fixed frame 272.
