Abstract

The utility model relates to a centre gripping width adjustable anchor clamps, including the cramping body, the both ends of this cramping body are passed through the cramping body and are linked together relatively, and the one end of the cramping body is passed through extension spring and is linked together, and the both ends inboard of the cramping body is equipped with slip mobilizable clamp splice, and two clamp splices are about cramping body center line symmetry, and the cramping body passes through the screw connection with the clamp splice of both sides, and the other end of the cramping body passes through torsion spring and connects two torsion arm of force, but torsion arm manual operation. The clamp has the advantages that the clamping process is greatly simplified through manual operation, the working cost is reduced, clamping of workpieces with various widths can be realized through adjusting the position of the clamping block, and secondary clamping can also be realized. The design structure is simple, the application range is wide, the cost is low, the operation is flexible, and the practicability is high.

Description

Clamp with adjustable clamping width

Technical Field

The utility model belongs to the technical field of machining, a centre gripping width adjustable anchor clamps is related to.

Background

And a device for fixing the processing object in the mechanical processing process so that the processing object has a correct position and the fixed processing object is subjected to construction or detection. May be referred to as a clamp.

The conventional clamp is generally immovable in workpiece processing, which limits flexibility of a position where a workpiece is placed by people, and a mechanism used by the movable clamp disclosed in the chinese patent 201820059222.4 can clamp and move the workpiece, but has the disadvantages of nonadjustable positioning distance, large volume and inconvenient operation, and cannot efficiently and quickly place the workpiece at a proper position.

Therefore, the utility model provides a centre gripping width adjustable anchor clamps adopts the manual torsion arm of force's of hand-held type centre gripping mode, realizes opening and tightening up of the holding body, by the centre gripping back, the clamp splice of holding body both sides can be through screw adjustment clamp splice position, has realized that the secondary presss from both sides tightly, and the commonality is strong, has overcome the operation inconvenient, difficulty such as bulky. Has good engineering value.

Disclosure of Invention

The technical proposal adopted by the utility model is as follows;

a clamp with adjustable clamping width comprises a tension and compression spring 1, a clamping body 2, a clamping block 3, a screw 4, a torsion arm 5 and a torsion spring 6; the two ends of the clamping body 2 are connected with a left torsion arm 5 and a right torsion arm 5, the upper end of the torsion spring 6 is fixedly connected with a round through hole in the middle of the right torsion arm 5, and the lower end of the torsion spring 6 is fixedly connected with a round through hole in the middle of the left torsion arm 5.

The clamping blocks 3 and the fixedly connected screws 4 are symmetrically distributed on two sides of the clamping body 2, the side walls of two sides of the clamping body 2 are respectively provided with symmetrical threaded holes, the front ends of the screws 4 are fixedly connected with the clamping blocks 3 through the threaded holes, and the clamping blocks 3 can be enabled to move horizontally towards the opposite direction or the opposite direction by adjusting the screws 4; both ends and the both ends of drawing and pressing spring 1 are fixed connection about the clamping body 2, are convenient for adjust the centre gripping distance in coordination with torsion spring 6 in the clamping process.

The beneficial effects of the utility model reside in that: the utility model relates to a centre gripping width adjustable anchor clamps adopts the cramping body of symmetrical arrangement to press from both sides tightly the work piece, utilizes screw adjustment grip block position, comes to adjust the centre gripping width of anchor clamps to the secondary that realizes the work piece presss from both sides tightly. The device adopts manual operation as external clamping force, and has the characteristics of flexible and variable clamping range, simple structure, convenient use and the like.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

referring to fig. 1, 2 and 3, a clamp with adjustable clamping width comprises a tension and compression spring 1, a clamping body 2, a clamping block 3, a screw 4, a torsion arm 5 and a torsion spring 6; the left end and the right end of the clamping body 2 are connected with a left torsion force arm 5 and a right torsion force arm 5, the upper end of the torsion spring 6 is fixedly connected with a round through hole in the middle of the right torsion force arm 5, and the lower end of the torsion spring 6 is fixedly connected with a round through hole in the middle of the left torsion force arm 5.

The clamping blocks 3 are symmetrically distributed on the inner sides of two sides of the clamping body 2, the side walls of two sides of the clamping body 2 are respectively provided with symmetrical threaded holes, the front ends of the screws 4 are fixedly connected with the clamping blocks 3 through the threaded holes, and the clamping blocks 3 can be enabled to move horizontally towards the opposite direction or the opposite direction by adjusting the screws 4; the front end of the clamping body 2 is fixedly connected with the two ends of the tension and compression spring 1 respectively, so that the clamping distance can be adjusted by the torsion spring 6 in cooperation with the clamping process.

The specific working process is as follows: during the use, when the torsional force arm 5 receives external force, the torsion spring 6 of the connection arm of force shrinks gradually under the drive of the torsional force arm 5, and the clamping body 2 enlarges certain angle this moment, extension spring 1 of the 2 front ends of clamping body is at the clamping body 2 angle enlargement simultaneously, certain tensile distance takes place thereupon, the work piece can be put into this moment, wait that the work piece slowly loosens the torsional force arm 5 after getting into, torsion spring 6 and extension spring 1 make the distance between clamp splice 3 diminish under the effect of self restoring force, until contacting completely and can pressing from both sides tight work piece completely, readjust screw 4 on the clamp splice 3 and make the work piece to the most suitable position and carry out the secondary and press from both sides tightly, work piece holder accomplishes once and presss from both sides tightly this moment.
