Description

Technical Field

[0001] The utility model relates to the technical field of pressure maintaining, in particular to an automatically locked pressure maintaining fixture. Background Art

[0002] A pressure-holding fixture is a device used to hold an object in a specific position or shape. Typically made of metal or other hard materials, it possesses sufficient strength and stability to prevent the object from moving or deforming. It is used in many different fields, including manufacturing, the automotive industry, and the aerospace industry.

[0003] For example, a pressure-holding jig disclosed in Chinese patent publication number N219673029U includes a base and a pressure-holding assembly, the pressure-holding assembly is detachably arranged on the base, and a first accommodating space for accommodating the product to be pressed is provided between the pressure-holding assembly and the base. The pressure-holding assembly is composed of at least two stacked pressure-holding units, and a second accommodating space for accommodating the product to be pressed is provided between two adjacent pressure-holding units.

[0004] Existing pressure-holding fixtures generally fix and press the workpiece to be pressure-held through upper and lower pressure plates when maintaining the position of the object, thereby completing the pressure-holding operation. However, for workpieces with irregular convex sides, fixing such workpieces requires customizing a lower pressure plate that fits closely to their sides for fixing, thereby increasing the processing cost of such workpieces. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that for workpieces with irregular convex sides, fixing such workpieces requires custom-made lower pressure plates that fit with their sides, thereby increasing the processing cost of such workpieces, and to propose an automatically locking pressure-maintaining fixture.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an automatically locking pressure-maintaining fixture, comprising a workbench and a locking groove, the locking groove is fixedly installed on the top surface of the workbench, the bottom surface of the workbench is fixedly installed with a mounting bin, a driving assembly is fixedly installed inside the mounting bin, one side of the driving assembly is transmission-connected with a driving splint, the driving splint comprises a mounting plate, one side of the mounting plate is fixedly installed with a side fitting plate, both ends of the driving splint are movably passed through a limiting long rod, both ends of the limiting long rod are fixedly installed with a base, a positioning baffle is fixedly installed on the inner side of the locking groove, and the other side fitting plate is fixedly installed on one side of the positioning baffle.

[0007] Preferably, the driving assembly includes a driving motor, the output end of the driving motor is transmission-connected to a screw rod, the outer side of the screw rod is transmission-connected to a driving block, and the driving block is fixedly connected to the driving splint via a connecting plate.

[0008] Preferably, a slide rail is symmetrically fixedly installed inside the locking groove, and a slide platform is slidably engaged with the outer side of the slide rail.

[0009] Preferably, a positioning platform is fixedly mounted on the upper end of the slide, and a positioning plate is symmetrically fixedly mounted on the top surface of the positioning platform.

[0010] Preferably, a plurality of positioning holes are evenly formed on one side of the two positioning plates.

[0011] Preferably, a plurality of the positioning holes are internally provided with positioning pins that are movable through them.

[0012] Preferably, a protective cushion is fixedly mounted on one side of the two positioning plates.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] In the utility model, the side bonding plate in the driving splint is composed of a polyether polyurethane foam sponge with slow rebound characteristics. When the uneven protrusions on the side of the workpiece contact the side bonding plate, the side bonding plate is squeezed and deformed, so that the side bonding plate positions and clamps the side of the workpiece. At the same time, the driving splint pushes the workpiece toward the positioning baffle, so that the other side of the workpiece is positioned and clamped with the other side bonding plate on the positioning baffle, thereby completing the automatic locking of the workpiece. Users do not need to customize specific splints to clamp and position workpieces with irregular convex shapes on the side, thereby reducing the cost of processing such workpieces.

[0015] 2. In the present invention, the positioning pin is passed through the hole on the protrusion at the bottom end of the workpiece, so that the workpiece is fixed and hung on the positioning table. When the driving clamp drives the workpiece to move horizontally, the bottom surface of the locking groove will not cause wear to the protrusion at the bottom end of the workpiece, and at the same time reduce the friction resistance on the bottom end of the workpiece, so that the driving clamp can better drive the workpiece to automatically lock and clamp.
