Embodiment

[0021] A kind of adjustable torque wrench of the present invention, as figure 1 As shown, it includes housing 2, lower baffle 1, wrench body 3, handle, ball 4, spring 5, and adjusting screw 8;

[0022] The housing 2 is a cylindrical member with an open lower end, the inner wall of the opening port of the housing 2 is processed with connecting threads, and the side wall of the housing 2 is provided with a ball passing hole;

[0023] The lower baffle 1 is a disc-shaped structure whose side wall is processed with an external thread matching the thread of the opening port of the shell 2, and the center of the lower baffle 1 is provided with a wrench hole;

[0024] The upper end of the wrench body 3 is a cylindrical section whose outer diameter matches the inner diameter of the inner cavity of the housing 2. The side wall of the cylindrical section is provided with hemispherical grooves uniformly distributed around the circumference, and a wrench rod extends vertically downward fro...

Abstract

The invention relates to a spanner with the adjustable moment of force, and belongs to the field of thread assembling. The spanner with the adjustable moment of force comprises a shell, a lower baffle, a spanner body, a handle, a ball, a spring and an adjusting screw. Semispherical grooves are uniformly distributed in the circumference of the side wall of the spanner body. The spanner body is sleeved with the shell, a hole is formed in the side wall of the shell to be connected with the handle, the adjusting screw is connected to the rear end of an inner cavity of the handle in a threaded mode, and the front end of the adjusting screw is connected with the ball through the spring. The ball is clamped into the grooves in the side wall of the spanner body under the action of elastic force of the spring, so that the spanner body and the handle are made to rotate synchronously to screw an assembled part; and when radial component force, generated by rotation of the handle to the ball, enabling the ball to slip out of the grooves in the side wall of the spanner body is larger than elastic force of the spring, the ball slips out of the grooves of the spanner body, and the spanner body cannot rotate relative to the assembled part when the handle is rotated. The slipping force of the ball is adjusted by adjusting the axial position of the adjusting screw in the inner cavity of the handle. The spanner with the adjustable moment of force meets the using requirements of different threaded assembled parts for different specific assembling moments of force.

Description

technical field [0001] The invention relates to a wrench with adjustable torque, which belongs to the field of thread assembly. Background technique [0002] When some assembly parts are threaded, it is necessary to control the axial pressure of the coil, and the control of the pressure is realized by controlling the assembly torque of the coil. A special controllable torque device is required for this purpose. Because existing torque wrenches are all classified according to models, and each type has a certain range. If using the torque wrench purchased at present, multiple types of different types are needed to meet the requirements of use. Bearings are installed in the torque wrench, which brings inconvenience to use and cost control. For this reason, it is necessary to have a device that can control the adjustment torque so as to meet the requirements of use. Contents of the invention [0003] The purpose of the present invention is to provide a wrench that can contr...
