Description

Assembly fixture with function of preventing false installation and detection Technical Field The invention belongs to the technical field of tools, and particularly relates to an assembly fixture with an anti-misloading detection function. Background The assembly fixture is commonly used for batch assembly of parts, and in the assembly process, although a common product is designed with an anti-reflection structure, the assembly fixture is only manually prevented from being assembled by mistake in the batch production process, and the fault tolerance is low, so that the assembly fixture does not meet the production requirements of high efficiency and high quality. The utility model provides a patent of 201510610035.1, a general disc brake pincers casing mistake proofing anchor clamps is disclosed, including mistake proofing positioner, elasticity pre-clamping device, hydraulic pressure linkage clamping device, mistake proofing positioner contains air pressure mistake proofing device, elasticity plunger mistake proofing device, side shift positioner, set up respectively on the three-point positioning seat of work piece below, support and work piece right side positioning seat about the work piece front end, realize the location mistake proofing through measuring air pressure and elasticity plunger flexible volume, elasticity pre-clamping device sets up in the both sides of work piece, stabilize the work piece with less elastic force in order to follow-up location and clamp. The four linkage hydraulic clamping devices are respectively arranged above the front end and the rear end of the workpiece, on the right side of the workpiece and on the front end face of the workpiece and are used for preventing the workpiece from being clamped in the upper and lower, front and rear and left and right directions of the moving warp. The prior art has the following technical problems: In the prior art, two products to be assembled are positioned in a full rigid way and clamped in a rigid way, no floating adaptation design exists, and therefore when workpieces, particularly plastic workpieces, are in non-parallel contact with the mounting surface and the positioning surface of the clamp, compression damage or stress deformation can occur for maintaining the compression force, and gaps are formed on the assembling surface.
