Abstract

The utility model discloses a kind of counter-force arms with torque sensor, it is made of torque sensor and counter-force support plate, the elastomer of torque sensor is cylindrical shape, it is received in one end and with internal spline, there is external splines in another end, the outer wall of elastomer is equipped with annular groove, and the foil gauge of torque sensor is arranged in annular groove;There is splined hole in one end of counter-force support plate, which is adapted to the external splines on the elastomer, and counter-force support plate is connected with torque sensor by spline housing.In use, the utility model and a torque tool are coordinated, then it is connect by lead receptacle data line with display equipment.During twisting bolt, the change in torque signal that torque sensor stress generates can be real-time transmitted to display equipment, can thus directly display the real-time torque value in screwing process on the display device.The utility model simple structure, it is easy to use.

Description

Counter-force arm with torque sensor
Technical field
The utility model is related to a kind of counter-force arms of tightening tool, and in particular to a kind of counter-force with torque sensor Arm.
Background technology
Up to now, in order to realize the accurate connection of bolt, torque tool usually all with torque control mechanism, passes through torsion Square control mechanism, torque tool can control bolted torque value in certain range, but this range needs Being tested on special test equipment can just learn.With the development of modern industry, people want to know to bolted torque value That knows is more accurate, that is to say, that after completing to be bolted, the connection torque value of the bolt is specially how many, such a It is expected, the tool with moment of torsion control can not meet at present.
Invention content
It cannot directly reflect the deficiency for being bolted torque the purpose of the utility model is to overcome existing torque tool, carry Go out a kind of counter-force arm with torque sensor, when it is used in combination with torque tool, can just directly display on the display device Real-time torque value in screwing process.
Realizing the technical solution of above-mentioned purpose is:A kind of counter-force arm with torque sensor, which is characterized in that it is by torque Sensor and counter-force support plate composition, the elastomer of torque sensor is cylindrical shape, is received in one end and with internal spline, another end There is external splines, the outer wall of elastomer is equipped with annular groove, and the foil gauge of torque sensor is arranged in annular groove;The counter-force support plate There is splined hole in one end, which is adapted to the external splines on the elastomer, and the counter-force support plate passes through with torque sensor Spline housing connects.
Further, sheath on the outer wall of the elastomer is housed, the lead receptacle of torque sensor is housed on sheath.
In use, the utility model and a torque tool are coordinated, i.e., the internal spline end cap of the utility model is connected on The external splines on torque tool head is put on, then is connect, and make counter-force support plate with display equipment by lead receptacle data line In a certain fixed object of tail portion gear in the work environment.During twisting bolt, the torque that torque sensor stress generates becomes Display equipment can be real-time transmitted to by changing signal, can thus directly display the real-time torsion in screwing process on the display device Square value.The utility model simple structure, it is easy to use.
Description of the drawings
Fig. 1 is the stereoscopic schematic diagram of the utility model one embodiment.
Fig. 2 is embodiment illustrated in fig. 1 partial sectional view.
Fig. 3 is the sectional view of the elastomer in embodiment illustrated in fig. 1.
Fig. 4 is schematic diagram when the utility model is used in combination with torque tool.
In figure:A, torque sensor, B, counter-force support plate, 1, elastomer, 1-1, annular groove, 1-2, internal spline, 1-3, external splines, 2nd, foil gauge, 3, sheath, 4, lead receptacle, 5, torque wrench, 5-1, square tenon, 5-2, external splines set, 6, sleeve.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, the utility model is made of torque sensor A and counter-force support plate B, the elasticity of torque sensor Body 1 is cylindrical shape, is received in one end of cylinder and with internal spline 1-2, there is external splines 1-3 in another end of cylinder, elastomer 1 Outer wall is equipped with annular groove 1-1, and the foil gauge 2 of torque sensor is arranged in annular groove 1-1;There is splined hole in one end of counter-force support plate B, The splined hole is adapted to the external splines 1-3 on elastomer, and counter-force support plate B and torque sensor A is socketed by spline.
In the present embodiment, sheath 3 on the outer wall of elastomer 1 is housed, the lead receptacle 4 of torque sensor is housed on sheath 3. The effect of sheath 3 is to protect elastomer 1 and foil gauge 2;Line jack 4 is used to connect external display equipment.
As shown in figure 4, the utility model and a torque tool are coordinated, i.e., the internal spline 1-2 of the utility model is covered It is connected on the external splines set 5-2 on 5 head of torque wrench, the sleeve 6 for covering connecting bolt is placed in the cylinder of elastomer 1, sleeve 6 Lower end coordinates, then pass through the data line of lead receptacle 4 and display with being screwed bolt cooperation, upper end and the square tenon 5-1 of torque wrench 5 Equipment connects, and the tail portion of counter-force support plate B is made to keep off in a certain fixed object in the work environment.During twisting bolt, turn round The change in torque signal that square sensors A stress generates can be real-time transmitted to display equipment, and this makes it possible to will be loaded on bolt Torque value real-time display come out.
The utility model can be used cooperatively with a variety of torque tools, and more is hydraulic torque wrench, secondly torque times Increase device and electric wrench.
