Transmission grinding clamp device

Abstract

The invention relates to a novel transmission grinding clamp device which is a set of processing clamping transmission device used for processing rotation surfaces such as excircles, inner circles and end surfaces of various small slender shaft parts in a choke and pump machining industry by common cylindrical grinding machines, internal grinding machines and surface grinding machines. The transmission grinding clamp device comprises a big bottom plate, an adjustable bottom plate, a clamp body, an adjusting wheel bracket, an adjusting wheel shaft, a belt pulley, synchronizing wheels, a synchronous belt, roller shafts, a positioning pin, a lock screw, a T-shaped lock block, a pinch roller bracket, a pinch roller, a pinch roller shaft, a pinch roller arm, a spring, a backing column, a column, a backing arm and a positioning stop pin; the lower part of the big bottom plate is mounted at a working table of the cylindrical grinding machine; an arc T-shaped groove and a positioning pin hole are formed in the upper part of the big bottom plate; the T-shaped lock block is mounted in the arc T-shaped groove; the positioning pin is mounted in the positioning pin hole; the adjusting bottom plate is mounted at the upper part of the big bottom plate, and connected with the T-shaped lock block and the big bottom plate through the positioning pin and the lock screw.

Description

technical field [0001] The invention relates to a new transmission grinding fixture device, which is a set of ordinary cylindrical grinders, internal grinders, surface grinders, tool grinders, etc. used for machining the outer circles of various slender shafts and small parts in the oil nozzle and oil pump industry. Clamping transmission device for processing rotating surfaces such as inner circles and end faces. Background technique [0002] At present, the transmission grinding fixture device used in the processing of small shaft parts in the oil nozzle and oil pump industry is that the workpiece is installed on the V-shaped bracket, and a driving wheel is used to press the workpiece and drive the workpiece to rotate. The driving wheel is usually a large friction coefficient. Made of rubber, this kind of fixture device, usually a set of fixtures can only be used for the processing of one process, and the clamping height and clamping angle of the workpiece cannot be changed...

[0002] At present, the transmission grinding fixture device used in the processing of small shaft parts in the oil nozzle and oil pump industry is that the workpiece is installed on the V-shaped bracket, and a driving wheel is used to press the workpiece and drive the workpiece to rotate. The driving wheel is usually a large friction coefficient. Made of rubber, this kind of fixture device, usually a set of fixtures can only be used for the processing of one process, and the clamping height and clamping angle of the workpiece cannot be changed, which is not conducive to the processing of small batches or multiple processes of a single part
