Abstract
The utility model discloses a kind of test spanner adjusting lining moment of torsion, belong to aircraft equipment technical field.Described spanner profile is circular configuration, and its endoporus is the internal spline coordinated with the external splines of adjustment driven worm screw one end of lining; The outer circumference surface of described spanner has been disposed radially boss, and is processed with installing hole along the thickness direction of described boss.During use, first adjustment lining lower end to be measured is fixed on support; Again wrench is inserted in from adjustment lining upper end, and installs with the one end fits that driven worm screw has an external splines shape; Then the upper end of adjustment lining and support are fixed, finally, torque wrench is connected on wrench, left-right rotation torque wrench, dial plate directly can show torque value.It is direct that described test fixture reads torque value, simple to operation.
Description
Technical field
The utility model relates to a kind of test spanner adjusting lining moment of torsion, belongs to aircraft equipment technical field.
Background technology
The repairing quality of aircraft seat directly affects the quality of aircraft, and aircraft seat ejection function is important Testing index when repairing aircraft seat.And regulating the size of the moment of torsion of lining to affect aircraft seat ejection, the moment of torsion regulating the rear II grade of ejection mechanism of lining combined type ejection mechanism assembling to vertically move required adjustment lining relative to I grade of ejection mechanism should be not more than 4.9Nm (50kgfcm).At present, the measurement of moment of torsion is generally realized by conventional torque wrench; Because in described adjustment lining, one end of driven worm screw is external splines shape, and the torque wrench of routine cannot realize the direct measurement to its moment of torsion, therefore, there is no effective test fixture and measures accurately regulating the moment of torsion of lining.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of test spanner adjusting lining moment of torsion, described spanner and conventional torque wrench with the use of, directly can read torque value, simple to operation.
The purpose of this utility model is realized by following technical scheme:
Adjust a torsion-testing spanner for lining, described spanner profile is cirque structure, and its endoporus is the internal spline coordinated with the external splines of adjustment driven worm screw one end of lining; The outer circumference surface of described spanner has been disposed radially boss, and is processed with polygon installing hole along the thickness direction of described boss;
Described polygon installing hole coordinates with the detection head of torque wrench.
During use, first adjustment lining lower end to be measured is fixed on support; Again wrench is inserted in from adjustment lining upper end, and installs with the one end fits that driven worm screw has an external splines shape; Then the upper end of adjustment lining and support are fixed, finally, the detection head of torque wrench is connected on the installing hole of wrench, left-right rotation torque wrench, the dial plate of torque wrench directly can show torque value.
Beneficial effect
(1) test fixture described in the utility model is provided with the wrench of an internal spline shape on the basis of conventional torque wrench, realizes the connection of torque wrench and adjustment lining to be measured, finally realizes the measurement of moment of torsion; For the repairing quality of aircraft seat provides guarantee;
(2) test fixture structure described in the utility model is simple, reads torque value directly, accurately during measurement, simple to operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of wrench described in the utility model;
Fig. 2 be adjustment lining described in the utility model with support coordinate figure;
Fig. 3 be test fixture described in the utility model with adjustment lining coordinate figure;
Wherein, 1-endoporus, 2-boss, the driven worm screw of 3-, 4-installing hole, 5-torque wrench.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments in detail the utility model is described in detail, but is not limited thereto.
Embodiment
Adjust a test spanner for lining moment of torsion, as shown in Figure 1, described spanner profile is circular configuration to its structural representation, and its endoporus 1 is the internal spline coordinated with the external splines of adjustment lining driven worm screw 3 one end; The outer circumference surface of described spanner has been disposed radially boss 2, and is processed with installing hole 4 along the thickness direction of described boss 2;
During use, first adjustment lining lower end to be measured is fixed on support; Again wrench is inserted in from adjustment lining upper end, and installs with the one end fits that driven worm screw 3 has an external splines shape; Then fixed in the upper end of adjustment lining and support, finally, be connected to by torque wrench 5 on the installing hole 4 of wrench, left-right rotation torque wrench 5 directly can show torque value (as Fig. 2 and 3).
The utility model includes but not limited to above embodiment, and every any equivalent replacement of carrying out under the principle of the utility model spirit or local improvement, all will be considered as within protection domain of the present utility model.
Claims (2)
1. adjust a test spanner for lining moment of torsion, it is characterized in that: described spanner profile is cirque structure, its endoporus (1) is the spline structure coordinated with the driven worm screw (3) of adjustment lining; The outer circumference surface of described spanner has been disposed radially boss (2), and is processed with polygon installing hole (4) along the thickness direction of described boss (2).
2. a test spanner for adjustment lining moment of torsion as claimed in claim 1, is characterized in that: described polygon installing hole (4) coordinates with the detection head of torque wrench.
