Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing and positioning technology, and more specifically, it relates to a positioning fixture for automotive parts. Background Technology

[0002] During the installation or processing of automotive parts, clamping and positioning fixtures are required. These fixtures position the parts for processing equipment, minimizing displacement that could affect processing quality and render the parts unusable. Existing positioning fixtures use mounting bases with suitable inner grooves to achieve stable positioning of the parts. However, replacing these mounting bases is cumbersome, lacking suitable quick-release mechanisms. Furthermore, processing different parts at different locations is cumbersome due to the lack of suitable rotation adjustment mechanisms. Additionally, the stability of rotation adjustment mechanisms after angle adjustment is poor, and there is a lack of suitable quick-locking adjustment mechanisms. Utility Model Content

[0003] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a positioning fixture for automotive parts, which solves the technical problems mentioned in the background art, such as the cumbersome disassembly and replacement of the mounting base, and the lack of a suitable quick disassembly and assembly mechanism for achieving stable positioning of parts by using a mounting base with a suitable inner groove model.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for automotive parts, comprising a fixed base, a U-shaped base at the bottom of the fixed base, the fixed base being rotatably disposed relative to the U-shaped base, a mounting base detachably disposed at the upper end of the fixed base, and multiple mounting bases having different inner groove types, a through groove on the fixed base, positioning rods at the four corners of the lower end faces of the multiple mounting bases, positioning holes corresponding to the multiple positioning rods on the upper end face of the fixed base, the multiple positioning holes communicating with the through groove, locking plates slidably disposed at both the left and right ends inside the through groove, locking rods symmetrically disposed on two locking plates, and locking holes corresponding to the locking rods on the multiple positioning rods.

[0005] The present invention is further configured such that an adjusting rod is rotatably provided on the fixed base corresponding to the through groove, and adjusting holes are provided on both locking plates corresponding to the adjusting rod. The adjusting rod and the adjusting holes are threadedly connected for easy sliding drive.

[0006] The present invention is further configured such that guide rods are symmetrically arranged inside the through groove, and guide holes are symmetrically opened on both locking plates corresponding to the guide rods, so as to guide the sliding of the locking plates.

[0007] The present invention is further configured such that the bottom end of the fixed base is provided with a rotating shaft, the rotating shaft is rotatably configured relative to the U-shaped base, and a rotary motor is connected to the bottom end of the rotating shaft to realize rotation drive.

[0008] The present invention is further configured such that a rotating ring is provided on the upper surface of the U-shaped base, and a rotating groove is provided on the bottom end of the fixed base corresponding to the rotating ring to ensure the rotation effect.

[0009] The present invention is further configured such that a limiting rod is provided through the top of the U-shaped base, and a limiting hole is provided at the bottom of the fixed seat corresponding to the limiting rod. Multiple limiting holes are provided in the circumferential direction of the fixed seat, so that stable positioning can be achieved after the angle is adjusted.

[0010] The present invention is further configured such that a limiting plate is provided at the bottom end of the limiting rod, and a spring is connected between the limiting plate and the inner wall of the top of the U-shaped base. The spring is fitted on the outer end of the limiting rod, and a U-shaped foot pedal is connected to the bottom end of the limiting plate, which facilitates quick limiting adjustment and automatic reset.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a positioning fixture for automotive parts, which has the following advantages: 1. Through the design of the mounting base, this tooling achieves rapid, precise positioning and reliable locking of multiple mounting bases with different inner groove models by setting positioning rods at the bottom of the mounting base, opening corresponding positioning holes and through slots on the fixed base, and setting locking plates and locking rods that can slide synchronously in the through slots. This is achieved in conjunction with the threaded adjustment rod. During replacement, simply rotating the adjustment rod simultaneously unlocks or locks the locking holes on all positioning rods, eliminating the need to operate the bolts one by one. This significantly improves the efficiency of changing different mounting base models, reduces equipment downtime, and adapts to the rapid changeover needs of producing a variety of parts.

[0012] 2. Through the design of the fixed base, the fixed base achieves relative rotation with the U-shaped base through the rotating shaft driven by the bottom rotary motor, and is supplemented by the structural design of the rotating ring embedded in the rotating groove, which provides stable, smooth and load-bearing rotation support for the fixed base. This structure allows the entire fixed base platform (along with the mounting base and workpiece on it) to be rotated accurately and smoothly to the required working angle, meeting the needs of processing or inspection in different positions, while ensuring the rigidity and stability of the rotation process.

[0013] 3. Through the design of the limiting rod, the limiting rod on the U-shaped base cooperates with multiple limiting holes distributed circumferentially on the fixed seat. Combined with the automatic reset locking force provided by the spring and the ease of operation of the foot pedal, efficient and stable locking of the rotation angle is achieved. The operator only needs to step on the U-shaped foot pedal (overcoming the spring force) to release the limiting position. After rotating the fixed seat to the target angle, releasing the foot pedal will cause the spring to push the limiting rod to automatically spring into the corresponding limiting hole, completing a reliable lock. This design not only ensures that the fixture maintains extremely high rigidity at any set angle, resisting external processing forces and preventing displacement, but also frees up the hands for foot operation, improving the safety and convenience of adjustment.
