Description
Technical field
The utility model relates to turns round torque wrench surely, specifically, relates to a kind of intelligent definite value torque wrench.
Background technology
Torque wrench is the requisite instrument of machinery industry, apply very extensive, when installation and removal screw bolt and nut, frequent needs accurately control the torque value size of bolt or nut, this just needs our torque wrench can measure the moment of torsion operationally exported in real time, on market, existing torque wrench is mostly pure frame for movement, the reading of inconvenient torque value and torque value error is larger.This is the deficiencies in the prior art part.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of intelligent definite value torque wrench, can arrange in real time, exports wrenching torque and show.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of intelligent definite value torque wrench, comprise tenon, it is characterized in that: described tenon connects one end of cross bar and swing arm, the other end connecting handle of described cross bar, described cross bar upper ring cap has sleeve pipe, described u pper s ide connects gripper shoe, described gripper shoe is provided with the gag lever post with through hole, the lower end of described swing arm is through the crushing block connecting cuboid after described through hole, the both sides of described crushing block are provided with pressure sensor, described crushing block and described pressure sensor contacts, described pressure sensor connection control device, described controller connects input key and display.
As the further restriction to the technical program, described display is charactron.
As the further restriction to the technical program, described controller adopts single-chip computer AT89C52.
As the further restriction to the technical program, described input key comprises 0-9 input key, removes button and determine button.
As the further restriction to the technical program, described pressure sensor adopts pressure-strain sheet.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is by the nominal torque of input key input service, the signal collected is sent to single-chip microcomputer by input key, when spanner works, swing arm drives crushing block squeeze pressure foil gauge, the size of force value is changed into the change of resistance value by pressure-strain sheet, and transfer signals in single-chip microcomputer, the resistance signal detected is converted into torque value by single-chip microcomputer, and show on charactron, when torque value reaches the input value of input key, numeral method numerical value carries out flicker and reports to the police.The utility model can set peak torque, in real time exports wrenching torque and numerical monitor, can Realtime Alerts when moment of torsion reaches maximum.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described in detail.
See Fig. 1 and Fig. 2, the utility model comprises tenon 1, described tenon 1 connects one end of cross bar 2 and swing arm 3, the other end connecting handle 4 of described cross bar 2, described cross bar 2 upper ring cap has sleeve pipe 5, gripper shoe 6 is connected on the upside of described sleeve pipe 5, described gripper shoe 6 is provided with the gag lever post 7 with through hole 8, the lower end of described swing arm 3 is through the crushing block 9 connecting cuboid after described through hole 8, the both sides of described crushing block 9 are provided with pressure sensor, described crushing block 9 and described pressure sensor contacts, described pressure sensor connection control device, described controller connects input key 11 and display.
Described display 12 is charactron.
Described controller adopts single-chip computer AT89C52.
Described input key 11 comprises 0-9 input key, removes button and determine button.
Described pressure sensor adopts pressure-strain sheet 10.
When this device works, by the nominal torque of input key 11 input service, the signal collected is sent to single-chip microcomputer by input key 11, when spanner works, on swing arm 3 squeeze pressure foil gauge, the size of force value is changed into the change of resistance value by pressure-strain sheet 4, and transfer signals in single-chip microcomputer, the resistance signal detected is converted into torque value by single-chip microcomputer, and show on charactron 12, when torque value reaches the input value of input key 11, charactron 12 shows numerical value and carries out flicker warning.
The utility model can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
