Abstract
The utility model discloses a floating compressing device which comprises a clamp body, a cam lever, a clamping column, a floating lever, a rocking arm and a clamping claw, wherein the cam lever is used as a force application device, and the clamping claw is used for compressing a workpiece. The floating compressing device is characterized in that a cam section is arranged on the cam lever, the driven end of the clamping claw tightly compresses the workpiece, the driving end of the clamping claw is connected with the clamping column, the clamping column is connected with the floating lever, an included angle is formed between the clamping column and the floating lever, the floating lever is connected on the rocking arm, a groove is formed in the rocking arm, the cam lever and the clamp body are in sliding connection, the cam section of the cam lever is arranged inside the groove of the rocking arm, the size of the cam section is matched with that of the groove, a pin shaft is arranged on the rocking arm, the pin shaft is abutted against the cam section of the cam lever, and a tension spring is arranged between the compressing end of the cam lever and the clamp body. The cam lever moves towards the direction of the compressing end under the applied force of the tension spring, and therefore the workpiece is tightly compressed.
Description
Technical field
The utility model belongs to the technical field of anchor clamps, relates in particular to a kind of unsteady hold down gag.
Background technology
In the machine-building process, anchor clamps commonly used fix processing object, make it to occupy correct position, to accept construction or to detect.In existing clamp assembly, workpiece is fixed in place by the coupling between himself physical form and the bare terminal end correspondingly-shaped.When practical operation, the clamping that the reciprocating motion by force application apparatus realizes workpiece with unclamp, too small as the application of force in implementing the process that workpiece clamps, can not well retrain workpiece; Excessive as the application of force, be easy to scratch surface of the work and damage jaw.
The utility model content
The technical problems to be solved in the utility model provides a kind of unsteady hold down gag, under the active force of extension spring, and clamping work pieces preferably.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of unsteady hold down gag, comprise chuck body, cam lever as force application apparatus, clamping column, floating lever; rocking arm and be used for the jaw of workpiece pressing; it is characterized in that: described cam lever is provided with cam segment; the driven end workpiece pressing of jaw; the drive end of jaw links to each other with clamping column; clamping column links to each other with floating lever; and clamping column and floating lever are an angle; floating lever is connected on the rocking arm; rocking arm is provided with groove; cam lever and chuck body are slidingly connected, and the cam segment of cam lever places in the rocking arm groove that size mates, rocking arm is provided with bearing pin; the cam segment of this bearing pin and cam lever offsets, the compressing of described cam lever hold and chuck body between be provided with extension spring.
The described end that compresses means that compressing extreme direction to cam lever moves, and workpiece can be impaction state, is on the cam lever away from the end of radius than the big cam section.
Compared with prior art, advantage of the present utility model is: during operation, make cam lever to moving away from the direction that compresses end, offset than the big cam section away from radius on bearing pin and the cam lever, the drive rocking arm moves upward, thereby drive floating lever and clamping column come-up, the jaw of workpiece top is also floated, thereby unclamp workpiece; Cam lever is not applied external force, cam lever moves to the direction that compresses end under the active force of extension spring, the less cam segment of bearing pin and radius offsets, the drive rocking arm moves downward, sink thereby drive floating lever and clamping column, the jaw of workpiece top is also sunk, thus workpiece pressing, under the active force of extension spring, clamping work pieces preferably.
Further, be threaded between described clamping column and the floating lever, be easy to dismounting, be convenient to replace.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the front view of the unsteady hold down gag embodiment of the utility model;
Fig. 2 is the side view of the unsteady hold down gag embodiment of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of unsteady hold down gag of the utility model, comprise chuck body 1, cam lever 2 as force application apparatus, clamping column 3, floating lever 4; Rocker arm 5 and be used for the jaw 6 of workpiece pressing 8; described cam lever 2 is provided with cam segment; the driven end workpiece pressing 8 of jaw 6; drive end of jaw 6 links to each other with clamping column 3; clamping column 3 links to each other with floating lever 4; and clamping column 3 and floating lever 4 are an angle; floating lever 4 is connected on the Rocker arm 5; Rocker arm 5 is provided with groove; cam lever 2 and chuck body 1 are slidingly connected, and cam lever 2 places in the Rocker arm 5 groove, and Rocker arm 5 is provided with bearing pin; the cam segment of this bearing pin and cam lever 2 offsets, and the end that compresses of described cam lever 2 is provided with extension spring 7.Be threaded between described clamping column 3 and the floating lever 4, be easy to dismounting, be convenient to replace.
The described end that compresses means that compressing extreme direction to cam lever 2 moves, and workpiece 8 can be impaction state, is on the cam lever 2 away from the end of radius than the big cam section.
During the utility model operation, make cam lever 2 to away from the direction motion that compresses end, offset than the big cam section away from radius on bearing pin and the cam lever 2, the drive Rocker arm 5 moves upward, thereby drive floating lever 4 and clamping column 3 come-ups, the jaw 6 of workpiece 8 tops is also floated, thereby unclamp workpiece 8; Cam lever 2 is not applied external force, cam lever 2 moves to the direction that compresses end under the active force of extension spring 7, the less cam segment of bearing pin and radius offsets, the drive Rocker arm 5 moves downward, thereby drive floating lever 4 and clamping column 3 sinkings, the jaw 6 of workpiece 8 tops is also sunk, thereby workpiece pressing 8, under the active force of extension spring 7, clamping work pieces 8 preferably.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
