Description

Pneumatic fixture for clamping multiple workpieces Technical Field The utility model relates to the technical field of clamps, in particular to a multi-workpiece clamping pneumatic jig. Background The pneumatic clamp for workpiece machining and fixing is an automatic clamp for realizing rapid clamping and loosening of workpieces by taking compressed air as a power source, and is widely applied to industrial scenes such as machining, assembly, welding and the like; The cylinder mounting position of traditional anchor clamps is fixed or can only one-way regulation, be difficult to adapt to the clamping point position demand of equidimension, shape work piece, when complex work piece such as batch processing step shaft, dysmorphism flange, because of X/Y axle direction regulation precision is not enough, often lead to the contact head unable accurate to lean on the work piece locating surface, cause the clamping deviation, influence the processing size uniformity, even need the reworking to handle, even fix the cylinder on the workstation through outside anchor clamps, although can promote the accuracy of cylinder mounting position adjustment, because the regulation of the clamping position of contact head is realized to the multidirectional position adjustment of needs to carry out to the cylinder, consequently, often need realize through four-way adjustment mechanism for whole adjustment process becomes complicated, and still need realize through extra increase and decrease gasket between external anchor clamps and the cylinder, can further increase the regulation degree of difficulty of cylinder mounting position. Disclosure of utility model The utility model aims to provide a multi-workpiece clamping pneumatic jig which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a pneumatic tool of multiplex spare clamping, includes the workstation, workstation bottom fixed mounting has the base, base one side fixed mounting has pneumatic control mechanism, one of them one end of pneumatic control mechanism is connected with outside air pump through the pipeline, fixed mounting has a plurality of bases on the workstation, a plurality of spouts have been seted up in the base, alternate in the spout and install Y to the governing pipe, alternate in the Y to the governing pipe and install X to the regulating block, be close to on the base Y is to still fixed mounting in the governing pipe department has the cylinder, the cylinder passes through the trachea and is connected with pneumatic control mechanism, one side fixed mounting has the stopper on the cylinder, movable mounting has the piston rod in the cylinder, piston rod one end fixed mounting has the contact head.
