Description
Technical field
The present invention relates to a kind of mechanical equipments, more particularly to a kind of torque wrench.
Background technique
Nut mainly cooperates shank body to act on collet chuck in knife handle system, makes collet chuck clamp-on tool；Locking for collet chuck,
It often will appear problem using common plate hand channel in production application；Since the torque value of spanner can not be fixed, if locking
Power not enough will cause nut not tight and be easy to loosen, and influence the assembly precision and dynamic balance of knife handle collet chuck, or even cause cutter
Fall off；And if the excessive violence nature that will result in nut of coupling mechanism force destroys or even damages entire cutter.Currently on the market
Torque wrench structure is excessively complicated and production cost is excessively high, and ordinary user will not usually use；And most of torque wrenches
It is monopolized by offshore company, sexual valence is relatively low.
Summary of the invention
The purpose of the present invention is providing a kind of torque wrench in view of the deficiencies of the prior art, structure is simple, at low cost,
Torque value can be set and torque is adjustable.
The technical scheme adopted by the invention to solve the technical problem is that: a kind of torque wrench, including driving end, wrenching bar
With reinforcing loop bar, the reinforcing loop bar is hollow housing, and upper end is equipped with connecting groove, and driving end and wrenching bar are overall structure,
The lower end bottleneck of driving end is equipped with boss, and the connecting groove of wrenching bar and the boss face of driving end lean, wrenching bar and plus
Power loop bar is connected structure, and is movably connected by rotary shaft, reinforces in loop bar and is additionally provided with steel ball and compressed spring, pulls
The lower end of hand lever is equipped with scarf, and the scarf is abutted against with steel ball outer surface, and the lower end of steel ball connects the compressed spring,
The lower end connection of compressed spring adjusts jackscrew, adjusts jackscrew and is threadedly coupled with the lower end inner wall for reinforcing loop bar.
Sealing leather sheath is additionally provided in the lower end of reinforcing loop bar.
The beneficial effects of the present invention are: the configuration of the present invention is simple, practical, when use, protrudes into nut in driving end
At bayonet, torsion reinforcing loop bar, when reaching setting torque value, steel ball touching reinforcing loop bar inner wall simultaneously issues clearly alarm sound,
Vibration can be felt on reinforcing loop bar, at this moment can stop locking；Easy to operate, time saving and energy saving and torque is adjustable.
Detailed description of the invention
Fig. 1 is schematic diagram of main cross-sectional structure of the invention；
Fig. 2 is left view structural representation of the invention.In figure:
1, driving end, 2. rotary shafts, 3. wrenching bars, 4. reinforcing loop bars, 5. steel balls, 6. compressed springs, 7. adjust jackscrew, 8. sealings
Leather sheath, 9. connecting grooves.
Specific embodiment
Technical solution of the present invention is further illustrated below by specific embodiment.
It is as shown in Figs. 1-2: a kind of torque wrench, including driving end 1, wrenching bar 3 and reinforcing loop bar 4, the reinforcing loop bar 4
For hollow housing, upper end is equipped with connecting groove 9, and driving end 1 and wrenching bar 3 are overall structure, and the lower end bottleneck of driving end 1 is set
There is boss, the connecting groove 9 of wrenching bar 3 and the boss face of driving end 1 lean, and wrenching bar 3 and reinforcing loop bar 4 are grafting knot
Structure, and be movably connected by rotary shaft 2, it reinforces and is additionally provided with steel ball 5 and compressed spring 6 in loop bar 4, under wrenching bar 3
End is equipped with scarf, and scarf is abutted against with 5 outer surface of steel ball, and the lower end of steel ball 5 is connected with compressed spring 6, compressed spring 6
Lower end connection adjusts jackscrew 7, and the jackscrew 7 that adjusts is threadedly coupled with the lower end inner wall of reinforcing loop bar 4；The present invention at work,
When the especially needed nut by knife handle system carries out elastic operation, nut need to be protruded at the bayonet in driving end 1, torsion adds
Power loop bar 4, when reaching setting torque value, the touching of steel ball 5 reinforcing 4 inner wall of loop bar simultaneously issues clearly alarm sound, in reinforcing loop bar 4
On can feel vibration, at this moment can stop locking.
When torsion reinforcing loop bar 4, torque can be transferred to steel ball 5 by rotary shaft 2, and steel ball 5 is final by compressed spring 6 again
It is transferred to and adjusts jackscrew 7；When reaching predetermined torque value, 5 position of steel ball can substantially be moved, and 3 end of wrenching bar chamfers face contact steel
5 part of pearl directly can cause the inner wall that power acts on reinforcing loop bar 4 to shake and issue alarm sound.In addition, the default of torque can
Torque is adjusted by adjusting jackscrew 7.The sealing leather sheath 8 is set in the lower end of reinforcing loop bar 4, for sealing the adjusting top
Silk 7 and the reinforcing intracorporal components of 4 shell of loop bar.
The configuration of the present invention is simple, it is practical, nut is protruded at the bayonet in driving end 1, torsion reinforcing loop bar 4 reaches
To when setting torque value, touching reinforcing 4 inner wall of loop bar of steel ball 5 simultaneously issues clearly alarm sound, can feel on reinforcing loop bar 4
Vibration, at this moment can stop locking, torque wrench not only can it is just tight again can eventually tightly；It is easy to operate, time saving and energy saving, torque is adjustable, this
Invention uses ergonomics optimization design, holds comfortable, to generate when reducing high-intensity operation torque spanner feeling of fatigue.
