Description
Technical Field
The utility model relates to the technical field of machinery, a flat tongs pincers body and movable vice jaw fit clearance add clamping apparatus specifically says so.
Background
In the machining industry, flat tongs are common technical equipment. The assembly precision of the flat tongs is different according to different use requirements. The sine flat tongs are high-precision flat tongs, and the fit clearance between the tongs body and the movable tongs mouth is not more than 0.02 mm. In order to ensure the high-precision fit clearance, the slide rail of the clamp body can be machined firstly, then the height dimension of the slide rail is measured, and then the sliding groove of the movable jaw is machined according to the height dimension, so that the fit clearance between the slide rail and the movable jaw is not more than 0.02 mm. Therefore, the processing can be carried out only by one piece, but not in batch, and the production efficiency is very low.
Disclosure of Invention
The utility model aims at providing a flat-nose pliers pincers body and movable vice jaw fit clearance add clamping apparatus, this anchor clamps can make the pincers body accomplish with the assembly reference surface one-time processing of movable vice jaw, have improved production efficiency.
In order to achieve the above purpose, the utility model adopts the following scheme: a flat-nose pliers clamp body and movable jaw fit clearance machining clamp comprises a positioning stop block, a supporting beam and a locking screw, wherein a left arm is arranged at the left end of the supporting beam, a right arm is arranged at the right end of the supporting beam, the left arm and the right arm form a U-shaped clamp body, a screw hole is formed in the middle of the right arm, the locking screw is arranged in the screw hole, the positioning stop block is arranged on a sucker of a grinding machine workbench, and a clearance gasket is arranged in an assembly clearance between a slide rail of a workpiece clamp body and the movable jaw.
During operation, the locating stop block is fixed on a sucker of a grinding machine workbench, a gap gasket is arranged between a clamp body slide rail and a movable jaw of the flat-nose clamp to be processed, the U-shaped clamp is arranged on the outer sides of the clamp body and the movable jaw, the left arm is abutted against the clamp body, the right arm is abutted against the movable jaw, then a locking screw is screwed, the clamp body and the movable jaw are integrally placed on the sucker, the clamp body is abutted against the locating stop block, the grinding machine is started, and meanwhile, the slide rail reference surface and the movable jaw reference surface are ground.
The utility model discloses flat-nose pliers pincers body and movable jaw fit clearance add clamping apparatus can reserve the pincers body and movable jaw's fit clearance, grinding slide rail reference surface and movable jaw reference surface simultaneously, make the pincers body of batch processing and movable jaw's fit clearance completely unanimous.
