Abstract
The invention discloses a kind of nested type spanner clamping device.The mechanism of grip bolt when tightening bolt for spanner, the mechanism is made up of fixed cover, sleeve, newel, back-moving spring and contact-making switch etc.；Newel and each specification sleeve are nested in inside fixed cover, and newel and each specification sleeve lower section are mounted on back-moving spring.Clamping device is placed on bolt turret head during grip bolt, turret head will be equal to and less than the sleeve jack-up of its size, and remaining sleeve realizes clamping；When newel or sleeve are pressed, corresponding contact-making switch is switched on, and can be used to recognize bolt specification.It is an advantage of the invention that clamping device is pressed by the sleeve of different size deacclimatizes the bolt of different size, simple operation is reliable and stable, and efficiency is higher；Installation contact-making switch in side's can be used for the size of collocation control system detection bolt specification and then realize the required torque value of automatic calculating under a bushing, improve the intelligence degree of spanner.
Description
Technical field
The present invention relates to a kind of nested type spanner clamping device, emergency first-aid repair task is especially adapted for use in and to connector pretightning force
Required precision occasion higher.
Background technology
Threaded connection is one of most widely used connected mode, there is substantial amounts of application in terms of civil equipment and military hardware.
Threaded connection is required for pretension, and pretightning force applying is improper to would potentially result in equipment fault, and major accident is likely to result in when serious.Mesh
Before, apply the main reliable experience of appropriate pretightning force and use two methods of torque wrench.Way by experience is widely used in
The less demanding occasion of pretightning force, this way error is larger, there is certain potential safety hazard.Control suitable pretightning force main
Numerical values recited being set using torque wrench, but due to the shortage of technical data, during using torque wrench and still relying on experience, this is just
Lose and use the meaning of torque wrench.Threaded connection applies improperly pretightning force will influence maintenance of works efficiency, increase it is artificial into
This, especially in terms of BDAR both, first-aid repair efficiency reduction would potentially result in bungling the chance of winning a battle, and lose the favourable situation in battlefield, cause tight
Weight consequence.
The sleeve of a whole set of specification often occurs in existing tool box, quantity there are 10~20, according to bolt when using
Specification selects corresponding sleeve.Can so cause work efficiency drop, and be unfavorable for the complete preservation of kit, some
The sleeve of specification will bring very big inconvenience once losing to maintenance work.
The content of the invention
For existing torque wrench application not enough extensively, intelligence degree is high, service efficiency is low and sleeve quantity is more etc.
Problem, the present invention nests together composition nested type clamping device by each specification sleeve.In mechanism's alternative tool case
A whole set of each specification sleeve, reduces tool heads quantity.
Nested type spanner clamping device of the present invention solves the technical scheme that its technical problem used：The mechanism by fixed cover,
A few part compositions such as sleeve, newel, back-moving spring and contact-making switch.Nested type spanner clamping device is by multiple specifications
Sleeve be combined, the sleeve of each specification is made after combination can work independently.When tightening certain sized bolt, clamping machine
Conformation sleeve is equally enclosed within above bolt turret head, smaller than bolt turret head specification and will be pushed up with its specification identical sleeve
Rise, the sleeve being adapted with bolt specification will be enclosed within and apply screw-down torque on bolt head.The mechanism is in each specification sleeve with
It is mounted with that contact-making switch serves as sensor below stem, for recognizing bolt specification, arranging in pairs or groups corresponding control system can be real
Existing automatic identification bolt specification, calculates corresponding required torque value, improves torque wrench intelligence degree.
The size of newel and each specification sleeve be according to the hexagonal area of bed of each sized bolt in the clamping device scope of application come
Determine.According to national standard data, C grades of conventional hexagonal bolt hexagonal area of bed and the corresponding nut size of same specification
It is identical, therefore nut is equally applicable to according to the clamping device that bolt hexagonal area of bed determines.The object that is applicable of the present invention is
C grades of conventional hexagonal hook bolt that standard GB/T/T 5780-2000 specify specify with GB/T 41-2000 C grades is commonly
First Series screw thread specification in the range of hex nut M5~M30, the clamping device that the present invention is provided is only applicable to applicable object
In the range of each sized bolt disassembling operations.
It is characteristic of the invention that clamping device rapidly adapts to bolt hexagonal area of bed, clamping is reliable and stable, and can arrange in pairs or groups control system
Automatic identification bolt specification is realized, spanner intelligence degree is improved.

Specific embodiment
Fig. 1 is referred to, nested type spanner clamping device is by fixed cover 101, sleeve 102, newel 103, back-moving spring
A few part compositions such as 104 and contact-making switch 105.
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are referred to, each top of sleeve 102 limited location boss 301 and limited impression 302,
Each specification sleeve 102 and newel 103 are mutually spacing to be nested among fixed cover 101, and back-moving spring 104 is installed on respectively
Specification sleeve 102 and the lower section of newel 103, for by sleeve 102 and the jack-up of newel 103, contact-making switch 105 to be pacified
The lower section of each specification sleeve 102 in bottom and newel 103 loaded on fixed cover 101.When using grip bolt of the present invention,
Clamping device is directly placed on bolt turret head, with hexagonal area of bed identical sleeve 102 or newel 103 and ratio
The small sleeve 102 of hexagonal area of bed or newel 103 will be depressed, and remaining sleeve 102 and fixed cover 101 realize folder
Bolt turret head is held, when sleeve 102 or newel 103 are depressed, corresponding contact-making switch 105 is switched on, contacted
Switch 105 can arrange in pairs or groups control system to recognize bolt specification as sensor.After tightening bolt end of operation, by the present invention
Separated with bolt turret head, sleeve 102 and newel 103 will return to original in the presence of back-moving spring 104 by jack-up
Beginning position, corresponding contact-making switch 105 also will be switched off.
