Abstract
The utility model relates to an intelligence torque wrench belongs to machinery, including the torque wrench body, set up compression spring, moment of torsion release joint and moment of torsion ejector pin in the body of torque wrench body, establish the piston between moment of torsion ejector pin and spring, set up pressure sensor on the piston, pressure sensor passes through the control system linking number and shows the speaker, can vocal count off and can the digital display, improves work efficiency greatly.
Description
Technical field
The utility model relates to a kind of intelligence dial torque wrench, belongs to mechanical field.
Background technology
Dial torque wrench-be also torque spanner or moment spanner, moment is exactly the product of power and distance, the moment size that control applies is needed, to ensure screw threads for fastening and to be unlikely to because of the excessive destruction screw thread of moment, so operating with dial torque wrench when threaded fasteners such as fastening screw bolt nuts. First setting the torque value upper limit of what a needs, when the moment of torsion applied reaches set(ting)value, spanner can send " Ka Ta " sound or some angles of spanner junction bending, and this does not want reinforcing again with regard to representative is fastening.
Dial torque wrench structure is divided into pressure spring, moment of torsion release joint and moment of torsion push rod three part, first rotary torque spanner afterbody revolve handle, revolve handle to be connected together by screw thread and dial torque wrench body and pass through thread fit, revolve handle propulsive torque push rod inwards, moment of torsion push rod compression spring, and then setting required torque value (being enclosed within moment of torsion push rod by spring to discharge joint to moment of torsion exert pressure), locking dial torque wrench, starts to tighten bolt. After bolt reaches torque value (pressure when using torsion to be greater than spring), the effect disconnected instantaneously can be produced. Sending joint in the moment of effect of occurring to disconnect instantaneously to knock, " Ka Ta " sound that spanner metal casing sends, thus confirms to reach the reminding effect of torque value.
This kind of spanner is very easy to use, substantially increases production efficiency, but also has inconvenience when some occasion uses:
1, part auto repair accessory screw threads for fastening moment is strict, not easily adjusts to regulation moment, reduces working efficiency;
2, repair in teaching link at vapour, usually being all one instructs personnel to instruct some students, student carries out fastening screw operation with dial torque wrench simultaneously, the moment spanner of part student may not adjust to regulation moment, " Ka Ta " sound can be sent equally, cause teacher can not and give student instruct or due to the improper damage accessory screw thread of moment.
Practical novel content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of can sounding count off and aobvious intelligent dial torque wrench can be counted, greatly increase work efficiency.
Intelligence dial torque wrench described in the utility model, comprise dial torque wrench body, pressure spring, moment of torsion release joint and moment of torsion push rod are set in the pipe body of dial torque wrench body, piston is established between moment of torsion push rod and spring, arranging pressure transmitter on piston, pressure transmitter is by the aobvious loud speaker of Controlling System linking number.
Piston also arranges displacement sensor, displacement sensor connection control system, dial torque wrench is by regulating the compression degree of pressure spring to set torque maximum in use, namely jacking moment of torsion push rod forward is got over, spring compression degree is more big, elastic force is more big, torque maximum is also more big, the stroke of moment of torsion push rod is read by displacement sensor, namely the peak torque set, and by signal transmission to Controlling System, when pressure transmitter is pressed, no matter pressure size, display screen and the loud speaker torque value that all directly output displacement sensor reads, such error is less, more accurate.
Principle of work and process
During work, conveniently operation regulates the torque value upper limit of dial torque wrench, then holding bolt operation is carried out, the pressure that now moment of torsion push rod can give piston certain, piston compressive pressure sensor, pressure transmitter is according to the big young pathbreaker's signal transmission of pressure to Controlling System, and Controlling System control display screen shows moment of torsion reading and control loudspeaker count off. When reaching prescribed torque value, moment of torsion release joint work, sends " Ka Ta " sound, confirms to meet requirement.
The useful effect that the utility model compared with prior art has is:
Intelligence dial torque wrench described in the utility model, piston compressive pressure sensor, pressure transmitter is according to the big young pathbreaker's signal transmission of pressure to Controlling System, and Controlling System control display screen display moment of torsion reading and control loudspeaker count off, when reaching prescribed torque value, moment of torsion release joint work, sending " Ka Ta " sound, such error is less, more accurately, simple to operate clear, it is very suitable for teaching practice.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, dial torque wrench body; 2, moment of torsion release joint; 3, pressure spring; 4, handle is revolved; 5, piston; 6, pressure transmitter; 7, Controlling System; 8, loud speaker; 9, moment of torsion push rod.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, intelligence dial torque wrench described in the utility model, comprise dial torque wrench body 1, pressure spring 3, moment of torsion release joint 2 and moment of torsion push rod 9 are set in the pipe body of dial torque wrench body 1, piston 5 is established between moment of torsion push rod 9 and spring, arranging pressure transmitter 6 on piston 5, pressure transmitter 6 is by the aobvious loud speaker 8 of Controlling System 7 linking number. piston 5 also arranges displacement sensor, displacement sensor connection control system 7, dial torque wrench is by regulating the compression degree of pressure spring 3 to set torque maximum in use, namely jacking moment of torsion push rod 9 forward is got over, spring compression degree is more big, elastic force is more big, torque maximum is also more big, the stroke of moment of torsion push rod 9 is read by displacement sensor, namely the peak torque set, and by signal transmission to Controlling System 7, when pressure transmitter 6 is pressed, no matter pressure size, display screen and loud speaker 8 torque value that all directly output displacement sensor reads, such error is less, more accurate.
Principle of work and process
During work, conveniently operation regulates the torque value upper limit of dial torque wrench, then holding bolt operation is carried out, now the pressure certain to piston 5 understood by moment of torsion push rod 9, piston 5 compressive pressure sensor 6, pressure transmitter 6 is according to the big young pathbreaker's signal transmission of pressure to Controlling System 7, and Controlling System 7 controls display screen display moment of torsion reading and control loudspeaker 8 count off. When reaching prescribed torque value, moment of torsion release joint 2 works, and sends " Ka Ta " sound, confirms to meet requirement.
