Abstract
The utility model provides a labor-saving wrench tool which comprises a fixed base, an adapter sleeve, a supporting plate, a pressing plate, a stud, a labor-saving device and a tooth-sleeved wrench, wherein the adapter sleeve is arranged on the fixed base; the outer casing of the product is connected and fixed by the fixed base; one end of the switching sleeve is connected with the fixed base, and the other end of the switching sleeve is connected with the supporting plate; the locking convex groove of the tooth sleeving wrench is matched and meshed with a 10mm groove at the 12-position inner diameter of the nut, the other side of the tooth sleeving wrench is connected with the labor saver through a spline, and the pressing plate is fastened through the stud, so that the labor saver is fixed. The utility model cancels the mode of tightening the nut by impact, and uses the labor-saving device and the tooth-sleeved spanner to tighten the nut during assembly, thereby providing continuous and stable tightening force, avoiding damage to the nut caused by impact tightening and improving the working efficiency and the operation safety; the problem that the nut cannot be screwed by the traditional screwing tool due to the fact that the structure and the size of the nut are changed is solved.
Description
Technical Field
The utility model belongs to the field of gas turbine assembly, and particularly relates to a labor-saving wrench tool.
Background
The labor-saving wrench has wide application range, has great effect on large nuts of medical appliances, military equipment, machine tools, hydraulic engineering and the like, and has various types and complicated functions, so that the technology of a plurality of companies in China for the labor-saving wrench is mature. But current laborsaving spanner can't provide continuous stable tightening force, and impact tightening causes the harm to the nut, exists the potential safety hazard in the assembly to there is big moment nut to screw up process moment measurement relevant problem, and the structure and the size of nut change can't accomplish the nut through traditional tightening frock and screw up.
Disclosure of Invention
The utility model aims to solve the problems that the structure and the size of a nut are changed and the nut cannot be screwed by the traditional screwing tool.
A labor-saving wrench tool comprises a fixed base, a switching sleeve, a supporting plate, a pressing plate, a stud, a labor-saving device and a tooth-sleeved wrench; the outer casing of the product is connected and fixed by the fixing base; one end of the switching sleeve is connected with the fixed base, and the other end of the switching sleeve is connected with the supporting plate; the locking convex groove of the tooth sleeving wrench is matched and meshed with a 10mm groove at the 12-position inner diameter of the nut, the other side of the tooth sleeving wrench is connected with the labor saver through a spline, and the pressing plate is fastened through the stud, so that the labor saver is fixed.
Further, a torque wrench is arranged on the labor saver.
The utility model has the beneficial effects that: compared with the prior product, the utility model cancels the mode of screwing the nut by impact, and screws the nut by using the labor-saving device and the tooth-sleeved wrench during assembly, thereby providing continuous and stable screwing force, avoiding damaging the nut by impact screwing and avoiding unsafe behavior of people during assembly, and further improving the working efficiency and the operation safety; is simple, portable and easy to operate. The problem that the nut cannot be screwed by the traditional screwing tool due to the fact that the structure and the size of the nut are changed is solved.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
1-2, a labor-saving wrench tool is characterized by comprising a fixed base 1, an adapter sleeve 2, a supporting plate 3, a pressing plate 4, a stud 5, a labor-saving device 6 and a tooth-sleeved wrench 7; the outer casing of the product is connected and fixed by the fixed base 1, so that the product is stopped in the process of screwing the nut; one end of the switching sleeve 2 is connected with the fixed base 1, and the other end is connected with the supporting plate 3 to play a role of switching; the locking convex groove of the tooth sleeving wrench 7 is matched and meshed with a 10mm groove at the 12 position of the inner diameter of the nut, the other side of the tooth sleeving wrench 7 is connected with the labor saver 6 through a spline, the pressing plate 4 is fastened through the stud 5, so that the labor saver 6 is fixed, when the nut is screwed, a torque wrench is arranged on the labor saver 6 for screwing, the screwing torque is 2000Nm, and the large torque is converted into a small torque when the nut is screwed through the transmission ratio of the internal gear of the labor saver, so that the stability and continuity requirements of the nut in the screwing process are met, and the technical method for screwing the nut and checking the screwing torque is completed without impact. The size of the tooth sleeving wrench 7 is about phi 270 multiplied by 87mm, and the net weight is about 6kg; the size of the adapter sleeve 2 is about phi 700 multiplied by 420mm, the net weight is about 20kg, and the tooling is made of 45# steel.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
