Pneumatic clamping jaw with adjustable clamping position

Abstract

The invention relates to a pneumatic clamping jaw with an adjustable clamping position. The pneumatic clamping jaw comprises a horizontally-arranged base, wherein a mounting plate is vertically fixed on the base; a driving device is fixed to the mounting plate and comprises an output shaft capable of stretching and retracting in the front-back direction; the mounting plate is provided with a through hole for the output shaft of the driving device to pass through; the pedestal is arranged on the base in a guiding and sliding manner, and the pedestal is elastically connected with the mounting plate; a guide rod is slidably arranged on the pedestal in a guiding mode, one end of the guide rod is in transmission connection with the output shaft of the driving device, and the other end of the guide rod is fixedly connected with a propelling block; the pedestal is fixedly connected with a hinge seat, two clamping jaws are hinged to the hinge seat, and the rear ends of the clamping jaws are in transmission connection with the propelling block; a buffer structure is arranged between the hinge seat and the propelling block; and a limiting block is arranged on the base in a position-adjustable manner, and the limiting block can stop and limit the pedestal in the front-back direction. For workpieces at different positions, only the position of the limiting block needs to be adjusted relative to the base, so that the operation is simple, convenient and rapid.

Description

technical field [0001] The invention belongs to the technical field of clamping devices, in particular to a pneumatic clamping jaw with adjustable clamping position. Background technique [0002] When processing or testing a product, it is often necessary to use a workpiece clamping device to move the product. Usually, the clamping position of the clamping device is fixed, and only the workpiece at the fixed position can be clamped. If the processing or detection position of the workpiece changes, it is necessary to adjust the entire workpiece according to the changed workpiece processing position or detection position. Only when the fixture is disassembled and adjusted, and then fixed and installed again, can the clamping position of the clamping device be changed to clamp the workpiece after the changed position, but the process of disassembling, adjusting and installing the clamping device takes a certain amount of time. resulting in reduced production efficiency.
