Problems solved by technology

However, this patent does not solve the problem of torque transfer and transmission when the installation space is narrow. After turning, it may still not be able to turn out of the narrow operating space, and then the torque wrench cannot be used to apply the preload.

Embodiment 1

[0034] Example 1: Two-module combination mode

[0035] Such as Figure 5As shown, the two torque adapter modules are connected into a double-module combination mode through a set of adapter sleeves and a transmission column. The depth of the hexagonal groove of the transmission column is greater than the length of the exposed hexagonal end of the torque adapter. The two ends of the adapter sleeve are respectively the first sleeve 12 and the third sleeve 14. One end of the first sleeve 12 with a hexagonal groove is connected with a part of a torque adapter with a hexagonal prism at one end. Two sleeves 14 have one end of the hexagonal groove and one end of the other torque adapter has a part of the hexagonal prism, and the second sleeve 13 is connected with the first sleeve 12 and the third sleeve 14 respectively by threads, By rotating the sleeve 13, the length of the adapter sleeve can be adjusted, because the depth of the hexagonal groove of the transmission column is grea...

Embodiment 2

[0036] Embodiment 2: Three-module combination mode

[0037] Such as Image 6 As shown, the three torque adapter modules are connected into a three-module combination mode through two sets of adapter sleeves and two transmission columns. On the basis of Example 2, one end of one of the torque adapters is connected to a set The connection mode of the torque adapter module is the same as that of embodiment 2, and will not be repeated here. Since the length and angle of the adapter sleeve between the two torque adapters are adjustable, the three-module combination mode can realize length and angle adjustment in two degrees of freedom directions, thereby adapting to different three-dimensional installation space requirements.

[0038] In addition to the above-mentioned embodiments, the modularized torque adapter of the present invention can select one module to perform operations according to the requirements of different installation conditions, or select multiple modules to perf...

Abstract

The invention discloses a modular torque adapter, which is used for realizing torque steering and transmission functions in a narrow structural space, is suitable for torque steering and transmissionwhen a fastener is mounted in the narrow space and has a certain requirement on pre-tightening force, and is mainly used for improving the assembly precision and efficiency of the mounted fastener. The modular torque adapter is composed of a torque adapter, an adapter sleeve, a transmission column and a screwdriver bit. Under different mounting conditions, different torque adapter modules are combined through the adapter sleeve and the transmission column, and the adapter function in a narrow space can be achieved. The outstanding advantages are that the modular torque adapter adopts the modular design, can be applied to different mounting conditions and has high applicability; the modular torque adapter is small in structure size, can extend into a small structure space, and has great practical value; and the modular torque adapter is low in cost, simple to operate and convenient to use, and has a large popularization and application space.

Description

technical field [0001] The invention relates to the field of tools, in particular to a modular torque transfer tool for torque transfer in a narrow space. Background technique [0002] In the field of machinery, some workpieces need to ensure that screws, nuts and other fasteners have a certain pre-tightening force when installed under specific working conditions. If the pre-tightening force is too large or too small, it will affect the use of the workpiece. , so it is necessary to ensure the pre-tightening force or moment when the fastener is pre-tightened. When it is necessary to apply a fixed torque pretightening force to fasteners such as screws and nuts, a torque wrench is often used. By adjusting the torque value on the wrench, a fixed torque value can be applied when the screw or nut is twisted. So as to meet the requirements of the working conditions or design indicators for the preload. But the handle part of the existing torque wrench is long, and when the pretig...
