Description
Technical field
This utility model relates to a kind of three-pawl type spanner clamping device, is especially adapted for use in emergency first-aid repair task and to connection
The occasion that part pretightning force required precision is higher.
Background technology
Threaded is one of most widely used connected mode, all has substantial amounts of in terms of civil equipment and military hardware
Application.The threaded pretension that is required for, pretightning force applying is improper would potentially result in equipment fault, is likely to result in great thing time serious
Therefore.At present, apply the main reliable experience of suitable pretightning force and use two kinds of methods of torque wrench.The way of dependence experience is by extensively
General for the less demanding occasion of pretightning force, this way error is relatively big, there is certain potential safety hazard.Control suitable pretension
Power mainly uses torque wrench, but due to the shortage of technical data, sets numerical values recited and still rely on warp when using torque wrench
Testing, this just loses the meaning using torque wrench.
Threaded applying pretightning force improperly will affect maintenance of works efficiency, increase cost of labor, especially rob in battlefield
Repairing aspect, first-aid repair efficiency reduction would potentially result in bungling the chance of winning a battle, and loses the favourable situation in battlefield, causes serious consequence.
Existing spanner is that two clamping faces apply pretightning force to bolt or nut mostly, and clamping face causes each compared with major general
The force ratio that clamping face bears is relatively big, is easily damaged the acting surface of bolt or nut.
Summary of the invention
Apply not extensively for existing torque wrench, intelligence degree is the highest, service efficiency is low, contact surface carries relatively
The problem such as big, this utility model is by using screw driven mode to realize the movement of mobile claw, and drive screw rotarily drives
Slide block moves, and utilizes double-slider mechanism, slide block to be moved through connecting rod and drives the movement of mobile claw.Mobile claw and stationary jaw
Move bolt or the nut adapting to different size relative to position.Potentiometer is installed link with drive screw, makes screw rod rotate
Drive potentiometer resistance adjusts, and potentiometer can be connected identification bolt specification as sensor with control system.
This utility model three-pawl type spanner clamping device solve its technical problem be the technical scheme is that by main body,
Drive screw, slide block, connecting rod, stationary jaw, mobile claw and potentiometer composition, stationary jaw is fixedly connected in main body, electricity
Position device is installed on body interior and is connected by gear with drive screw；The shape of bolt turret head and nut is positive six limits
Shape, therefore, the design aspect on the mobile route of two mobile claws, two mobile claws must assure that three cards when moving
The clamping face angle holding 60 ° of pawl and three's spacing can not become.Therefore allowing the mobile guide groove angle of two mobile claws is 60 °,
Stationary jaw is positioned at the point of intersection of two mobile guide grooves so that three claws are maintained at the position, summit of an equilateral triangle at any time
Put；The mobile use double-slider mechanism of mobile claw realizes, therefore uses two double-slider mechanisms to be used in conjunction with same slide block
Driving two mobile claws to move, the spacing this ensures that thering three claws is the most equal, it is achieved that stable holding is each simultaneously
The bolt of specification or nut.
According to GB data, C level conventional hexagonal bolt turret head size and the corresponding nut size phase of same specification
With, therefore the clamping device determined according to bolt turret head size is equally applicable to nut.The object that this utility model is suitable for is
The C level conventional hexagonal that the C level conventional hexagonal hook bolt that standard GB/T/T 5780-2000 specifies and GB/T 41-2000 specify
Each sized bolt in the range of nut M5～M30.
Feature of the present utility model is stepless changing clamping device openings of sizes, and the scope of application is relatively wider, three clamping faces
Common clamping, operate more stable reliably, sensor control system of can arranging in pairs or groups is installed and realizes automatically identifying bolt specification, improve
Spanner intelligence degree.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, three-pawl type spanner clamping device is by main body 202, drive screw 101, slide block 102, connecting rod
103, stationary jaw 104, mobile claw 105 and potentiometer 201 form, and stationary jaw 104 is fixedly connected on current potential in main body 202
Device 201 is installed on main body 202 inside and is connected by gear with drive screw 101.
Three the clamping action face angles referring to Fig. 1, Fig. 2, stationary jaw 104 and two mobile claws 105 are 60 °,
The moving direction of two mobile claws 105 is 60 °, and stationary jaw 104 is positioned at the mobile guide groove intersection point position of two mobile claws 105
Put, this guarantees stationary jaw 104 and two mobile claws 105 are always positioned at the position, three summits of an equilateral triangle
Put, it is ensured that optional position all can clamp held part 106 simultaneously.
Referring to Fig. 1, Fig. 2, Fig. 3, slide block 102, connecting rod 103 and mobile claw 105 form double-slider mechanism, slide block 102
Being connected with drive screw 101 by the way of threaded engagement, rotary drive screw rod 101 can realize the movement of slide block 102, slide block
The movement of 102 can drive again the movement of mobile claw 105, which achieves rotary drive screw rod 101 to adjust clamping device
Openings of sizes is to adapt to the held part 106 of different size.Main body can be connected with pinch bar for 202 times.Potentiometer 201 and biography
The mode (see Fig. 3) that dynamic screw rod 101 uses gear to connect, rotary drive screw rod 101 adjusts the same of the position of mobile claw 105
Time also drive the change of potentiometer 201 resistance, potentiometer 201 can be connected to identify bolt rule as sensor and control system
Lattice.When using this utility model to clamp certain sized bolt, the movement of rotary drive screw rod 101 meeting band movable slider 102, slide block 102
It is moved through connecting rod 103 to drive mobile claw 105 to move to realize the change of mobile claw 105 and stationary jaw 104 spacing and fit
Bolt specification clamped by should, can directly clamp use after being adjusted to suitable dimension.
