Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a high-efficiency manual tool for taking out an elastic pin in a deep hole. Background Art

[0002] Some special parts have higher temperature requirements during operation, so they need to be designed with more and deeper cooling water holes. Elastic pins and cooling water pipes need to be installed in the holes. When installing, special tools are used to install the elastic pins to a fixed position and then insert the cooling water pipes to fix them.

[0003] However, when the part is disassembled for inspection and maintenance, after the cooling water pipe is pulled out, the elastic pin is installed too deep from the plane and cannot be taken out for inspection. In order to solve this problem, the existing method is to use a long and thin iron wire to make an iron hook shape, insert it into the deep hole and slowly hook out the elastic pin. However, when the elastic pin and the inner hole wall size are tightly matched, there is no way to take out the elastic pin.

[0004] To this end, we propose an efficient hand tool for removing elastic pins in deep holes. Utility Model Content

When the gear ring is rotated, the gear ring rotates and drives the telescopic rod to move upward through the cooperation of the thread teeth and the thread groove, so that it can be adjusted according to holes of different depths.

[0011] Preferably, an anti-skid groove is provided on the outer wall surface of the gear ring to prevent the hand from slipping during rotation.

[0012] Preferably, the locking mechanism includes a stop screw, a slide tube is fixedly connected inside the telescopic rod, a connecting rod is slidably connected inside the slide tube, a telescopic head is fixedly connected to the top surface of the connecting rod, an expansion port is provided on the outside of the top of the telescopic rod, a buckle is fixedly connected to the outer surface of the top of the telescopic rod, a moving groove is provided inside the top of the outer side of the rod body, a connecting block is fixedly connected to the bottom surface of the connecting rod, a stop screw is meshed and connected inside the connecting block, and the stop screw is located inside the moving groove, and mounting holes are sequentially provided at the bottom end of the inner wall of the rod body. When the position of the device is adjusted, the stop screw is operated to be pulled downward, and the stop screw moves in the moving groove. The stop screw moves through the connecting block to drive the connecting rod to move downward, and the connecting rod moves downward to drive the telescopic head to move downward together. The telescopic head moves downward to squeeze the top of the telescopic rod, so that the diameter of the expansion port position of the telescopic rod head increases, and the elastic pin plane in the deep hole can be clamped by the buckle fit.

[0014] Preferably, a rubber sleeve is installed on the outer surface of the hand hammer to increase friction.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the gear ring is operated to rotate, and the gear ring rotation drives the telescopic rod to move upward through the cooperation of the threaded teeth and the threaded groove, so that it can be adjusted according to holes of different depths. After the position is adjusted, the stop screw is operated to pull downward, and the stop screw moves in the moving groove. The stop screw moves through the connecting block to drive the connecting rod to move downward, and the connecting rod moves downward to drive the telescopic head to move downward together. The telescopic head moves downward to squeeze the top of the telescopic rod, so that the diameter of the expansion port position of the telescopic rod head increases, and the snap fit can be used to clamp the plane of the elastic pin in the deep hole. When the elastic pin in the deep hole is clamped, the operating hand hammer slides on the outer surface of the sliding column, and the hand hammer is pulled downward to impact the fixed block, giving the entire rod body an inertial impact force, and the elastic pin in the deep hole is gradually brought out of the deep hole through continuous impact force, and finally the elastic pin in the deep hole is removed.
