Description

Technical Field

[0001] This utility model relates to an assembly fixture, specifically to a production line assembly fixture with a limiting function. Background Technology

[0002] In the assembly line field, the positioning accuracy and stability of fixtures directly affect product quality. Existing fixtures generally use fixed limit blocks, leading to frequent fixture changes or manual adjustments of positioning elements for workpieces of different sizes. This is inefficient and makes it difficult to guarantee repeatable positioning accuracy. Clamping mechanisms often rely on direct bolt locking, which is prone to loosening under continuous vibration, causing workpiece displacement. Furthermore, when assembling thin-walled components, traditional fixtures lack a central support structure, and circumferential clamping forces can easily cause the central area of ​​the workpiece to collapse and deform. With the increasing demand for automated production, the fixture adjustment mode, which relies on manual intervention, has become a bottleneck for production line flexibility. Utility Model Content

The clamping structure is located above the fixture base and clamps and limits the parts to be produced. A support structure is provided in the center of the fixture base to support the center of the parts and prevent them from deforming under stress during assembly.

[0005] As a preferred technical solution, the clamping structure includes an array of electrically operated telescopic rods arranged around the base of the clamp and an adjustment plate; The clamp base is provided with guide grooves on all four sides, and the guide block at the front end of the adjustment plate passes through the guide groove and is connected to the output shaft of the electric telescopic rod, so that the adjustment plate can be moved by the electric telescopic rod. The adjustment plate is provided with a limiting surface and a product placement surface; a clamping plate is positioned on the limiting surface by a limiting structure, and by adjusting the position of the clamping plate on the limiting surface, product clamping and limiting can be adapted to different ranges; the clamping plate is locked by a locking structure to prevent the clamping plate from loosening and shifting, thus affecting clamping.

[0006] As a preferred technical solution, the limiting structure includes multiple sets of limiting holes disposed on the limiting surface and limiting posts disposed at the bottom of the clamping plate; The limiting post is inserted into the limiting hole of the limiting surface, thereby limiting the clamping plate.

[0007] As a preferred technical solution, the locking structure includes a locking plate and locking screws; The locking screw is disposed on the locking plate, and the locking end of the locking screw passes through the locking plate and is placed in the locking hole of the limiting surface, thereby achieving the fixation of the clamping plate.

The clamp base has a lifting groove in the center, and the support plate is placed in the lifting groove. The output shaft of the electric lifting rod passes through the bottom of the clamp base and is connected to the support plate in the lifting groove. The electric lifting rod drives the support plate to extend, thereby supporting the center of the accessory.
