Wherein preferred, described circular hole B with establish the copper sheathing connected with circular hole B interference between left push rod, left push rod can move vertically in copper sheathing, to reduce the friction between left push rod and circular hole B.
Wherein preferred, linked together by floating junction between described left push rod and the piston rod of cylinder.
Wherein preferred, limited block is all established in one end of described each line slideway, to limit the shift position of slide.
The utility model is arranged on the workbench of edge knurling machine by pedestal, two knurled wheel Working positions of the corresponding edge knurling machine of its middle left and right chuck, during work, one end of workpiece is inserted in the workpiece hole of left chuck, then start cylinder, cylinder promotes left chuck, makes the other end of workpiece enter the workpiece hole of right chuck, material loading completes, and starts processing; Knurled wheel, when workpiece, can realize the location of workpiece by slide.
The utility model compared with prior art tool has the following advantages:
1, adopt Pneumatic charging, material loading position, away from the knurled wheel position rotated, without the need to manual pusher, not only reduces the danger of staff, and reduces the labour intensity of staff;
2, Pneumatic charging and clamping work pieces, can carry out machinery adjustment to workpiece centre position, location prepares, and material loading is stablized, and not only improves working (machining) efficiency, and ensures machining accuracy and product quality;
3, reduce the overall processing time, save processing cost, simplify procedure of processing;
4, simply, cost taken by themselves is low for structure, technique, and operation is convenient, is convenient to maintenance.
