Abstract

This invention relates to a mechanized tool. The purpose of the invention is to increase reliability and serviceability by shifting the center of mass of the rotor relative to its axis of rotation and ensuring that the wrench is pressed against the tightened threaded joint. When compressed air is supplied to the pipe 20, it passes through the air inlet channel 6 into the central blind hole 9 of the shaft 8, then through the through radial channels 10, from them into the spiral-shaped grooves 14 and out into the cavity 15 of the cylinder. During the release of compressed air from the spiral-shaped grooves 14 of the caps 12 and 13, a reactive force arises, under the action of which the rotor 5 rotates. As the rotor 5 rotates, an alternating force is generated, creating a vibrating moment that is transmitted to the wrench 7 and the latter compounds. At the same time, the compressed air through the pipeline 20 enters the piston cavity 19 of the pneumatic cylinder 16 and moves the piston 12 with the rod 18, which interacts with one of the parts of the assembled product, while simultaneously wrenching the nut to the nut of the tightening threaded joint. 1 hp f-ly, 2 ill.

Claims (2)

Claim 1. A wrench containing a housing, a pneumatic actuator housed therein, including a cylinder, a rotor installed therein and an air supply and exhaust ducts and a nut head, characterized in that, with a reliability chain, the pneumatic actuator rotor is made in the form of a shaft with a central blind hole communicating with an air supply channel and through radial channels extending into the central blind hole rigidly connected to the shaft sec5. a torus and two covers, each of which is fixed to the corresponding end of the sector and has spiral grooves on the end facing the latter, each of which is communicated at one end with a corresponding radial channel, the other with the cylinder cavity, and the nut head is placed in the housing in an eccentric axis pneumatic drive and. made with a conical prismatic hole designed to interact with the side faces with a nut of a tightened threaded connection. 2. Wrench pop. 1, with the aim that, in order to improve serviceability, it is equipped with a pneumatic cylinder mounted on a housing coaxially to the screw head with a piston with a rod located therein, 1Q designed to interact with the surface of the product and connected to the bosom, the lead-in channel .
