Abstract
The utility model discloses a cam clamping device which comprises clamp main body, a clamping claw in sliding connection with the clamp main body, a swinging block hinged on the clamp main body and a push rod serving as a force application device. The driven end of the clamping claw is used for pressing a work piece, a groove is arranged at the driving end of the clamping claw, the driven end of the swinging block is arranged in the groove, the driving end of the swinging block is a pin roller, the push rod and the clamp main body are in sliding connection, cam sections are arranged on the push rod, the pin roller abuts against the cam sections, and a tension spring is arranged at the pressing end of the push rod. When the cam clamping device is operated, the push rod is downwards pulled, the cam section with the large radius abuts against the pin roller on the left, the clamping claw is driven to rotate in a clockwise mode to clamp the work piece, and the work piece can be well clamped under the action force of the tension spring. When the push rod is upwards pushed, the cam section with the small radius abuts against the pin roller on the left, and the clamping claw can rotate in an anticlockwise mode to loosen the work piece.
Description
Technical field
The utility model belongs to the technical field of anchor clamps, relates in particular to a kind of cam clamping device.
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 cam clamping device, under the active force of 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 cam clamping device, comprise the jaw that is slidingly connected for chuck body, with chuck body, be hinged on the chuck body swinging block and as the push rod of force application apparatus, it is characterized in that: the driven end of jaw is used for workpiece pressing, have groove on the drive end of jaw, the driven end of swinging block places in the groove, the drive end of swinging block is roller, described push rod and chuck body are slidingly connected, have cam segment on the push rod, roller and cam segment offset, and the end that compresses of push rod is provided with extension spring.
The described end that compresses means that compressing extreme direction to push rod moves, and workpiece can be impaction state, is on the push rod away from the end of radius than the big cam section.
Compared with prior art, advantage of the present utility model is: during operation, pull down push rod, radius offsets than the roller in big cam Duan Yuqi left side, and drive jaw and clockwise rotate clamping work pieces, under the active force of extension spring, clamping work pieces preferably; Upwards promote push rod, the roller in the less cam segment of radius and its left side offsets, and the drive jaw rotates counterclockwise and unclamps workpiece.
Further, the homonymy that described swinging block contacts with push rod is provided with returns piece, when push rod when returning piece and offset, can make jaw unclamp workpiece.
Further, described chuck body is provided with backstay, and the dorsal part of backstay and swinging block offsets, and backstay can limit the hunting range of swinging block, and the dorsal part of described swinging block means the opposite side that swinging block contacts with push rod.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the structural representation of the utility model cam clamping device embodiment.
The specific embodiment
As shown in Figure 1, a kind of cam clamping device of the utility model, comprise jaw 2 for chuck body 1, clamping work pieces, be hinged on the chuck body 1 swinging block 3 and as the push rod 4 of force application apparatus, the driven end workpiece pressing of jaw 2 has groove 5 on the drive end of jaw 2, the driven end of swinging block 3 places in the groove 5, the drive end of swinging block 3 is roller, and described push rod 4 is slidingly connected with chuck body 1, has cam segment on the push rod 4, roller and cam segment offset, and the end that compresses of push rod 4 is provided with extension spring 6.The homonymy that described swinging block 3 contacts with push rod 4 is provided with returns piece 7, when push rod 4 when returning piece 7 and offset, can make jaw 2 unclamp workpiece.Described chuck body 1 is provided with backstay 8, and backstay 8 offsets with the dorsal part of swinging block 3, and backstay 8 can limit the hunting range of swinging block 3, and the dorsal part of described swinging block 3 means the opposite side that swinging block 3 contacts with push rod 4.
In the utility model when operation, pull down push rod 4, and radius offsets than the roller in big cam Duan Yuqi left side, and drive jaw 2 and clockwise rotate clamping work pieces, under the active force of extension spring 6, clamping work pieces preferably; Upwards promote push rod 4, push rod 4 with return piece 7 and offset, drive jaw 2 and rotate counterclockwise and unclamp workpiece.
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.
Claims (3)
1. cam clamping device, comprise the jaw that is slidingly connected for chuck body, with chuck body, be hinged on the chuck body swinging block and as the push rod of force application apparatus, it is characterized in that: the driven end of jaw is used for workpiece pressing, have groove on the drive end of jaw, the driven end of swinging block places in the groove, and the drive end of swinging block is roller, described push rod and chuck body are slidingly connected, have cam segment on the push rod, roller and cam segment offset, and the end that compresses of push rod is provided with extension spring.
2. cam clamping device as claimed in claim 1, it is characterized in that: the homonymy that described swinging block contacts with push rod is provided with returns piece.
