Abstract
The utility model involves a wrench, especially involving a round nut torque wrench. The round nut torque wrench of the utility model is unique in that: a torque wrench is included; whose clamping part is a hook wrench with an arc head, with entad protuberance on the end of the arc. The practical effects of the utility model are: it is applicable to the machine manufacturing industry, specially preload of nut round by thrust bearings lock of precision lead screw of machine tool manufacturing, tightening torque of round nut is precisely controlled, thus the preload force of thrust bearings on the end of the lead screw is precisely controlled, the assembly quality is good, and the service life of the thrust bearings is significantly extended.
Description
(1) technical field
The utility model relates to spanner, the special-purpose torque wrench of particularly a kind of round nut.
(2) background technology
At present, machinery manufacturing industry is particularly in the machine-tool industry, various precision lead screws need be locked with round nut with thrust bearing, and the bad control of the pretightning force of round nut, the too little meeting of pretightning force causes becoming flexible, then shorten the service life of thrust bearing too greatly, therefore need a kind of spanner that can accurately control screw-down torque of exploitation.
(3) summary of the invention
The utility model can accurately be controlled the special-purpose torque wrench of round nut that screw-down torque is controlled the pretightning force of round nut in order to remedy the deficiencies in the prior art thereby provide a kind of.
The utility model is achieved by the following technical solution:
The special-purpose torque wrench of round nut of the present utility model, its special character is: comprise a torque wrench, its retaining part is the hook-headed wrench that head is circular arc, and the end of circular arc has the projection towards the inboard.
The beneficial effects of the utility model are, be applicable to the particularly pretension of the various precision lead screws usefulness of machine-tool industry thrust bearing stripped nut of machinery manufacturing industry, can accurately control the screw-down torque of round nut, thereby accurately control the pretightning force of the thrust bearing of leading screw end, assembly quality is good, has prolonged the service life of thrust bearing significantly.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 hook-headed wrench, 2 torque wrenches, 3 round nuts, 4 moment of torsion graduation marks, 5 torque adjustment handles.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
The special-purpose torque wrench of round nut of the present utility model comprises a torque wrench 2, and its retaining part is the hook-headed wrench 1 that head is circular arc, and the end of circular arc has the projection towards the inboard.
The special-purpose torque wrench of round nut of the present utility model, it is the special-purpose device for screwing up of a kind of novel thrust bearing stripped nut, it realizes controlling the moment of torsion of hook-headed wrench by the torque wrench 1 that is installed in hook-headed wrench 2 ends, and moment of torsion is according to the rules tightened round nut 3.Its end is to hook the hole on the round nut or the special-purpose hook-headed wrench of groove, and the other end is to have the torque wrench that is used for accurately controlling screw-down torque of regulating the moment device, and its afterbody has torque adjustment handle 5 and moment of torsion graduation mark 4.During use at first the torque adjustment handle by the spanner end regulate and use moment, then with the gib head end hook of spanner on the round nut that needs are tightened, slowly round nut is tightened in reinforcing, represents that screw-down torque reaches when hearing that spanner sends " snap " signal sound.
Claims (1)
1. the special-purpose torque wrench of a round nut, it is characterized in that: comprise a torque wrench (2), its retaining part is the hook-headed wrench (1) that head is circular arc, and the end of circular arc has the projection towards the inboard.
