Compared with the present method for drilling the split pin, the clamp for drilling the split pin has simple operation, time and labour saving, work efficiency and quality improving and waste and cost decreasing.

Description

Bore the cotter-pin hold clamp

Technical field

The utility model relates to a kind of clamp forceps, specifically a kind of brill cotter-pin hold clamp.

Background technology

Hole in split pin at present, dotting punch was beaten in line more before this, and then the end with pliers grasp opening pin goes boring, the method for above-mentioned boring, though existing widespread usage also has the some shortcomings part: the one, line, dotting punch are operated cumbersome, waste time and energy; The 2nd, the easy deflection of holing is bored the easier deflection of cotter-pin hold especially on the split pin threaded one end, often produce waste product and the drill bit that fractures, and causes waste, increases cost.

Summary of the invention

The purpose of this utility model is to provide a kind of aided process that saves line, beats dotting punch, and is simple to operate, time saving and energy saving, improves work efficiency and quality, cuts the waste the brill cotter-pin hold clamp that reduces cost.

For reaching above purpose, technical solution adopted in the utility model is: this brill cotter-pin hold clamp, it is characterized in that it is by last pincers handle, lower clamp handle, upper grip head, lower pliers head, rivet, screw, slotted hole, cylindrical slideway, positioner, drill jig, the drill jig set bolt constitutes, last pincers are being connected upper grip head and lower pliers head respectively with an end of lower clamp handle, upper grip head is connected with rivet with lower pliers head, form a fulcrum of lever, center position in upper grip head one side is offered slotted hole, screw is fixed on the both sides of upper grip head by slotted hole, form the application point of lever, cylindrical slideway is located at the center of lower pliers head, on lower pliers head, also be provided with positioner, drill jig is located at the top center of upper grip head, and fixes with the drill jig set bolt, the center line in drill jig hole must with the central lines of lower jaw.The utility model is also implemented by following measure: described positioner, constitute by backstay and backstay set bolt, and backstay is fixed with the backstay set bolt after inserting the through hole of lower pliers head.When using the utility model, after the split pin locating surface is close to the backstay big end surface, screwed in place bar set bolt, hold upper and lower pincers then clamping work pieces, adjust drill bit again, make the center of the centrally aligned drill jig of drill bit pierce split pin, after having bored the hole, mention drill bit, loosening upper and lower pincers handle takes off split pin.

The beneficial effects of the utility model are: with compare at present in the method for split pin boring, have simple to operately, time saving and energy saving, improve work efficiency and quality, cut the waste and the advantage of cost.
