Problems solved by technology

Due to the large number of nut specifications, it is usually necessary to be equipped with various types of sleeves. The construction between different nuts requires constant replacement of sleeves, and the construction efficiency is low.
Most of the existing universal sleeves adopt the technical scheme of arranging multiple steel needles inside the traditional sleeve; because the steel needles are small, the steel needles will be deformed and damaged when the torque is large, and cannot provide sufficient tightening torque, so they cannot be used for tightening large nuts. At the same time, the center of the fastening nut and the center of the sleeve usually do not coincide, and the eccentric vibration is serious when rotating
The existing sleeve torque control usually adopts the technical solution of the sensor, which is expensive, difficult to maintain, and difficult to apply on a large scale

Embodiment 1

[0023] Example 1, such as figure 1 and figure 2 The shown universal torque sleeve of the present invention includes: a sleeve 1, a clamp block 2 and a spring 3, the end of the sleeve 1 has a notch, and the side wall of the notch has a sleeve inclined chute 11; the clamp block There is a clamp block inclined chute 21 on the 2, and the clamp block 2 and the sleeve 1 are connected through the sleeve inclined chute 11 and the clamp block inclined chute 21, and the clamp block 2 can slide obliquely in the notch; One end of the spring 3 tightens the bottom of the sleeve 1, and the other end tightens the tail of the clamp block 2; when the clamp block 2 is pushed against the nut, it can automatically open and automatically clamp the nut; the universal torque sleeve can be used for various specifications of nuts or special-shaped Continuous tightening of parts does not require frequent replacement of the sleeve head; when the torque reaches the design value, the clamp block 2 can be...

Embodiment 2

[0024] Example 2, such as figure 1 and figure 2 The torque adjustment principle of the universal torque sleeve of the present invention has three forces in the direction parallel to the axis of the inclined chute 11 of the sleeve. 1. Spring 3 pairs clamp block 2 in the parallel direction of the sleeve inclined chute 11 axis parallel component force of spring 3, the friction force between clamp block 2 and sleeve 1; the parallel component force of nut is greater than the parallel component force and friction of spring 3 When the force is summed, the clamping block 2 slides along the oblique slide groove 11 of the sleeve, the clamping block 2 opens, the fastening is completed, and the fastening torque reaches the design value.

[0025] When the clamp block 2 turns the nut, the nut produces a tangential reaction force on the clamp block 2 in the tangential direction of the rotation circle, and the nut produces an opening reaction force on the clamp block 2 in the radial directi...

Embodiment 3

[0026] Example 3, such as figure 1 , figure 2 and image 3 As shown in the torque adjustment method of the universal torque sleeve of the present invention, the elastic force is changed by changing the length of the spring 3, and then the torque is adjusted; the length of the spring 3 is adjusted by increasing the gasket 4 or increasing the length adjustment mechanism 5.

Abstract

The invention provides a universal torque sleeve composed of a sleeve body, a clamping block and a spring. The sleeve has the functions of a universal sleeve and a torque sleeve at the same time. The clamping block can be automatically opened when abutting against a nut and automatically clamps the nut. The universal torque sleeve can be used for continuous fastening operation of nuts of various specifications or special-shaped parts, and a sleeve head does not need to be replaced frequently. When the torque reaches a design value, the clamping block is automatically opened; the universal torque sleeve can automatically adjust the torque according to the size of the nut; and the torque of the universal torque sleeve can be manually adjusted. The generated torque is large, and deformation is not prone to occurring; the axis of the nut coincides with that of the universal torque sleeve, and vibration during rotation is avoided; and the torque is controlled by adopting a force balance principle, the cost is low, and maintenance is easy.

Description

technical field [0001] The invention relates to a sleeve, and more specifically, relates to a universal torque sleeve that can automatically adjust its size to adapt to the rotation of various specifications of nuts or non-standard parts and can control the torque. Background technique [0002] Sockets are common construction tools. Due to the large number of nut specifications, it is usually necessary to be equipped with various types of sleeves. The construction between different nuts requires constant replacement of the sleeves, and the construction efficiency is low. Most of the existing universal sleeves adopt the technical scheme of arranging multiple steel needles inside the traditional sleeve; because the steel needles are small, the steel needles will be deformed and damaged when the torque is large, and cannot provide sufficient tightening torque, so they cannot be used for tightening large nuts. At the same time, the center of the fastening nut and the center of ...
