Cam-type axial rotary punching tool

Abstract

The invention relates to a cam-type axial rotary punching tool. The cam-type axial rotary punching tool comprises a rotation driving component and a punching component, wherein the rotation driving component comprises a driving shaft, and a rotation driving cylinder and a first cam block which are sequentially sleeved on the driving shaft and fixedly connected with each other; the punching component comprises a second cam block which is matched with the end surface of the first cam block, a first limiting structure in axial sliding connection with the second cam block, an elastic component sleeved on the driving cylinder, and a second limiting structure arranged at one end of the elastic component; the other end of the elastic component presses against the second cam block; and the driving shaft drives the first cam block to rotate through the rotation driving cylinder so as to drive the second cam block to move in the axial direction in the telescopic stroke of the elastic component for generating a punching acting force. The cam-type axial rotary punching tool can provide rotating and punching acting forces at the same time, has a relatively low requirement on sealing performance, and can be matched with a power drill for use.

Description

technical field [0001] The invention relates to the field of drilling tools, more specifically, to a cam type axial rotary punching tool that simultaneously provides rotating force and impact force. Background technique [0002] At present, most of the drilling tools commonly used in oil fields can only provide a single torque rotation force. When drilling with this kind of drilling tools for hard formations or abrasive formations, the formation is often damaged due to lack of sufficient force, so the drill bit is easy. Drill sticking, wear and other phenomena occur, which reduces the service life of the drill bit and virtually increases the cost, and the drilling speed is low, which affects the drilling efficiency. [0003] The current solution to the above problems at home and abroad is to study a rotary percussion drilling tool that increases the impact force on the basis of the rotary force. The commonly used tools are divided into two categories. One is to use high-pres...

Problems solved by technology

[0004] The object of the present invention is to provide a cam-type axial rotary punching tool that provides both rotation and impact forces by mechanical action, which not only solves the problems of low efficiency and high cost of drilling tools with only rotation force, but also due to The present invention relies on mechanical action to provide force, has low requirements on sealing performance, and does not produce pulse action, so it can be used in conjunction with power drilling tools, which solves the problem of hydraulic and pneumatic impactors requiring high sealing performance and incompatibility with power Problems with drilling tool combination
