Abstract
The utility model discloses a nested formula spanner fixture. Clamping bolt's mechanism when being used for spanner tighten the bolts, this mechanism comprises fixed cover, sleeve, center post, reset spring and contact switch etc. The center post is inside in fixed cover with each specification sleeve nestification, and reset spring is all installed with each specification sleeve below to the center post. Overlap fixture on hexagon bolt during clamping bolt, the hexagon head will equal and be less than the sleeve jack -up of its size, and centre grippings are realized to all the other sleeves, when center post or sleeve were pressed, corresponding contact switch was put through, can be used to discern bolt specification. The utility model has the advantages that fixture is pressed the bolt of deacclimatizing different specifications through the sleeve of different specifications, the simple operation, and reliable and stable, efficiency is higher, contact switch can be used to arrange the big or small of control system detection bolt specification and then the required torque value of realization automatic calculation in sleeve below installation, improves the intelligent degree of spanner.
Description
Technical field
This utility model relates to a kind of nested type spanner clamping device, is especially adapted for use in emergency first-aid repair task and the occasion that connector pretightning force required precision is higher.
Background technology
Threaded is one of most widely used connected mode, all has substantial amounts of application in civil equipment and military hardware.The threaded pretension that is required for, pretightning force applying is improper would potentially result in equipment fault, is likely to result in major accident time serious.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 widely used in the less demanding occasion of pretightning force, and this way error is relatively big, there is certain potential safety hazard.Controlling suitable pretightning force and mainly use torque wrench, but due to the shortage of technical data, set numerical values recited and still rely on experience during use torque wrench, this just loses the meaning using torque wrench.Threaded applying pretightning force improperly will affect maintenance of works efficiency, increase cost of labor, especially in BDAR both, first-aid repair efficiency reduce would potentially result in bungling the chance of winning a battle, lose the favourable situation in battlefield, cause serious consequence.
Often occurring the sleeve of a whole set of specification in existing workbox, quantity does not have 10～20 not etc., selects corresponding sleeve according to bolt specification during use.So causing work efficiency drop, and be unfavorable for that the complete of kit preserves, the sleeve of some specification is once lose and will bringing very big inconvenience to maintenance work.
Summary of the invention
For the application of existing torque wrench not extensively, the problem such as intelligence degree is not high, service efficiency is low and sleeve quantity is many, this utility model is nested together by each specification sleeve and forms nested type clamping device.A whole set of each specification sleeve in this mechanism's alternative tool case, reduces tool heads quantity.
This utility model nested type spanner clamping device solves its technical problem and be the technical scheme is that this mechanism is made up of several parts such as fixed cover, sleeve, newel, back-moving spring and contact switches, newel and each specification sleeve are installed among fixed cover, and back-moving spring and contact switch are installed on below newel and sleeve.Nested type spanner clamping device is to be combined by the sleeve of multiple specifications, each specification sleeve is mutually nested and utilizes the boss of sleeve and groove to carry out mutually spacing, the sleeve making each specification after combination all can work alone, for clamping each sized bolt turret head, back-moving spring is used for jack-up newel and sleeve.When tightening certain sized bolt, clamping device is enclosed within above bolt turret head as sleeve, and the sleeve little and more identical with its specification than bolt turret head specification will by jack-up, and the sleeve adapted with bolt specification will be enclosed within bolt head and apply screw-down torque.Sensor serves as at the contact switch mounted below of each specification sleeve and newel in this mechanism, is used for identifying bolt specification, and corresponding control system of arranging in pairs or groups can realize automatically identifying bolt specification, calculates corresponding required torque value, improves torque wrench intelligence degree.
The turret head size that the size of newel and each specification sleeve is according to sized bolt each in the clamping device scope of application is determined.According to GB data, the C level conventional hexagonal bolt turret head size of same specification is equivalently-sized with corresponding nut, 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 standard GB/T/T5780-2000 C level conventional hexagonal hook bolt specified and First Series screw thread specification within the scope of GB/T41-2000 C level conventional hexagonal nut M5～M30 specify, the disassembling operations that the clamping device of this utility model offer is only applicable within the scope of applicable object each sized bolt.
Feature of the present utility model is that clamping device rapidly adapts to bolt turret head size, clamps reliable and stable, and control system of can arranging in pairs or groups realizes automatically identifying bolt specification, improves spanner intelligence degree.

Detailed description of the invention
Refer to Fig. 1, nested type spanner clamping device is made up of several parts such as fixed cover 101, sleeve 102, newel 103, back-moving spring 104 and contact switches 105, newel 103 and each specification sleeve 102 are installed among fixed cover 101, and back-moving spring 104 and contact switch 105 are installed on below newel 103 and sleeve 102.
Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, equal limited location boss 301 and limited impression 302 above each sleeve 102, each specification sleeve 102 and newel 103 are mutually spacing to be nested among fixed cover 101, back-moving spring 104 is installed on below each specification sleeve 102 and newel 103, for by sleeve 102 and newel 103 jack-up, contact switch 105 is installed on each specification sleeve 102 in bottom of fixed cover 101 and the lower section of the back-moving spring 104 of newel 103 correspondence.When using this utility model grip bolt, clamping device is directly placed on bolt turret head, the sleeve 102 equivalently-sized with turret head or newel 103 and the sleeve 102 less than turret head size or newel 103 will be depressed, remaining sleeve 102 and fixed cover 101 realize grip bolt turret head, when sleeve 102 or newel 103 are depressed, corresponding contact switch 105 is switched on, and contact switch 105 can arrange in pairs or groups control system to identify bolt specification as sensor.Tight a bolt after end of operation, this utility model separated with bolt turret head, sleeve 102 and newel 103 by under the effect of back-moving spring 104 by jack-up, return to home position, corresponding contact switch 105 also will be switched off.
