Description

A hydraulic clamping fixture for down-the-hole drill bit gear pressing machine

technical field

The utility model relates to a drill bit clamp, in particular to a hydraulic clamping clamp for a down-the-hole drill bit gear pressing machine.

Background technique

Down-the-hole drill bits are also called high-pressure down-the-hole drill bits. There are four main types of head end face designs: namely, the head end face convex type, the head end face flat type, the head end face concave type and the head end face deep concave center type. . Cemented carbide mostly uses button teeth, elastic teeth, or a shared tooth arrangement method for both button teeth and elastic teeth. It acts on the tail of the drill bit through the impact force, frequency and torque of the drilling rig to transmit the energy to the alloy, and the alloy acts on the rock to crush the rock, and then the broken stone is released from the slag discharge groove gap at the head of the drill bit through high air pressure discharge.

Many large drill bits are driven by hand. The quality of the product is not easy to guarantee, and the stability is not good. Therefore, a special gear press machine is required for tooth pressing. However, the clamping of large drill bits is more troublesome, and it is not easy to rotate the angle quickly. This fixture It is a good solution to this kind of problem. The chuck of the fixture can be moved to the outside of the gear press machine through the screw rod to lift the drill bit into the fixture, and then moved to the inside of the gear press machine. The angle and rotation angle can be automatically adjusted by the hydraulic device for different positions. The alloy is compacted to ensure the stability of the product, and it can ensure the safety and speed of the processing process, improve work efficiency and reduce the labor intensity of workers, and can also ensure the stability and consistency of all products.
