Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and more specifically, to a testing fixture that is easy to disassemble. Background Technology

[0002] Inspection fixtures are a type of tooling used in the automotive industry to inspect the shape and dimensions of irregular parts (such as plastic parts for interior and exterior car trim, or body sheet metal). This structure is often used on the handheld profilograph module of the inspection fixture to simulate the tightening function between the product's clips and plastic parts during the actual product installation process, thereby simulating the positioning state between products.

[0003] In the past, during the inspection process between products and fixtures, the rigid contact between the product and the fixture's positioning block after installation easily damaged the product during disassembly and assembly. This hook-and-pin structure replaces the traditional rigid contact, allowing for damage-free disassembly and assembly through mechanism movement. Furthermore, the disassembly and assembly process is more convenient, requiring less force than physical assembly. This effectively improves the inspection efficiency of products on the fixture and reduces the defect rate caused by product damage due to improper disassembly during inspection. Therefore, an easily disassembled inspection fixture is proposed to solve these problems. Utility Model Content

[0004] To overcome the aforementioned shortcomings of the prior art, embodiments of this utility model provide an easily disassembled inspection fixture. The technical problem this utility model aims to solve is that in the past, during the inspection process between products and fixtures, the rigid contact between the product and the fixture's positioning block after installation easily damaged the product during disassembly and assembly. This hook-and-pin structure replaces the traditional rigid contact, allowing for damage-free disassembly and assembly through mechanism movement. Furthermore, the disassembly and assembly process is more convenient, requiring less force than physical assembly. This effectively improves the inspection efficiency of products on the fixture and reduces the product defect rate caused by improper disassembly and damage during the inspection process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a testing fixture that is easy to disassemble, comprising a base assembly, wherein a plurality of frame assemblies are provided on the surface of the base assembly, and each frame assembly is provided with a telescopic component; The telescopic assembly includes a central rod with a positioning groove on its surface. One end of the central rod is fixedly connected to an outer rod, and the other end of the central rod is fixedly connected to a screw. The other end of the screw is fixedly connected to a side rod, and the other end of the side rod is fixedly connected to a limiting plate. A pin is fixedly connected to the other side of the limiting plate, and a handle is sleeved on the surface of the pin. A limiting pin 1 is rotatably connected to the inner cavity of the positioning groove, and multiple limiting pins 2 are symmetrically arranged on the surface of the outer rod.

The handle and the insert are fixedly connected by bolts. After the multiple limit pins are connected to the multiple positioning grooves on the outer rod surface, the center rod, outer rod, screw, side rod and insert are prevented from sliding out of the guide block and affecting use. It also makes disassembly and assembly more convenient, and makes it easier to repair and replace parts in the later stage, and can also reduce material waste.

[0009] In a preferred embodiment, the first limiting groove and the second limiting groove are interconnected, the guide block intersects with the center rod, and the threaded grooves on the surfaces of the limiting nut and the tightening adjustment block intersect with the screw. The guide block and the return spring only have an intersecting relationship. In later use, the stop position of the first limiting pin can be directly limited by the two limiting grooves of different lengths, the first limiting groove and the second limiting groove. After being locked with the screw by the limiting nut and the tightening adjustment block, it can be adjusted to a suitable locking position, so as not to affect the later movement effect.
