Abstract
The utility model discloses a cam pressing device which comprises a clamp main body, a connection rod in sliding connection with the clamp main body, a tension spring, a clamping claw for clamping a work piece and a cam rod serving as a force application device. The cam pressing device is characterized in that the clamping claw is hinged on the clamp main body, the driven end of the clamping claw can clamp the work piece, the driving end of the clamping claw is hinged with the connection rod, one end, far away from the clamping claw, of the connection rod abuts against cam sections of the cam rod, the cam sections are curves with the radiuses increasing gradually, and the tension spring is connected between the pressing end of the cam rod and the clamp main body. When the cam pressing device is operated, the cam rod can move in the direction away from the pressing end, the connection rod abuts against the cam section with the small radius, and the connection rod descends to drive the clamping claw to rotate in a clockwise mode to loosen the work piece on the left. When external force is not applied to the cam rod, the cam rod can move to the pressing end under the action of the tension spring, the connection rod abuts against the cam section with the large radius, the connection rod rises to drive the clamping claw to rotate in an anticlockwise mode to clamp a work piece on the left of the clamping claw, and the work piece can be well clamped.
Description
Technical field
The utility model belongs to the technical field of anchor clamps, relates in particular to a kind of cam pressing 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 pressing device, 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 cam pressing device, the connecting rod that comprises chuck body, is slidingly connected with chuck body, extension spring, be used for the jaw of clamping work pieces and as the cam lever of force application apparatus, described jaw is hinged on the chuck body, the driven end clamping work pieces of jaw, drive end and rod hinge connection, connecting rod offsets away from an end of jaw and the cam segment of cam lever, cam segment is that radius becomes big curved surface gradually, and extension spring is connected compressing between end and the chuck body of cam lever.
The described end that compresses means to cam lever and compresses extreme direction motion, and workpiece can be impaction state, is on the cam lever end away from the less cam segment of radius.
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, the less cam segment of connecting rod and radius offsets, and connecting rod descends, and drives jaw and clockwise rotates, and unclamps the workpiece in jaw left side; Cam lever is not applied external force, to the direction motion that compresses end, the cam segment that connecting rod and radius are bigger offsets cam lever under the active force of extension spring, connecting rod rises, and drives jaw and rotates counterclockwise, and clamps the workpiece in jaw left side, under the active force of the utility model extension spring, clamping work pieces preferably.
Further, also comprise spring, pass bearing pin on the described connecting rod, an end of spring is connected with bearing pin, and the other end is connected with chuck body, by the active force of spring, makes connecting rod drive the jaw workpiece pressing.
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 utility model cam pressing device embodiment;
Fig. 2 is the side view of the utility model cam pressing device embodiment.
The specific embodiment
As depicted in figs. 1 and 2, a kind of cam pressing device of the utility model, comprise chuck body 1, connecting rod 2, extension spring 3, be used for the jaw 4 of clamping work pieces 7 and as the cam lever 5 of force application apparatus, described jaw 4 is hinged on the chuck body 1, the driven end clamping work pieces 7 of jaw 4, drive end and connecting rod 2 are hinged, and connecting rod 2 offsets away from an end of jaw 4 and the cam segment of cam lever 5, cam segment is that radius becomes big curved surface gradually, and extension spring 3 is connected the end that compresses of cam lever 5.During operation, make cam lever 5 to moving away from the direction that compresses end, the less cam segment of connecting rod 2 and radius offsets, and connecting rod 2 descends, and drives jaw 4 and clockwise rotates, and unclamps the workpiece 7 in jaw 4 left sides; Cam lever 5 is not applied external force, cam lever 5 moves to the direction that compresses end under the active force of extension spring 3, the cam segment that connecting rod 2 and radius are bigger offsets, connecting rod 2 rises, driving jaw 4 rotates counterclockwise, clamp the workpiece 7 in jaw 4 left sides, the utility model is under the active force of extension spring 3, and clamping work pieces 7 preferably.
The utility model also comprises extension spring 6, passes bearing pin on the described connecting rod 2, and the lower end of spring is connected with bearing pin, and the upper end is connected with chuck body 1, by the active force of extension spring 6, makes connecting rod 2 drive jaw 4 workpiece pressings 7.
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 (2)
1. cam pressing device, the connecting rod that comprises chuck body, is slidingly connected with chuck body, extension spring, be used for the jaw of clamping work pieces and as the cam lever of force application apparatus, it is characterized in that: described jaw is hinged on the chuck body, the driven end clamping work pieces of jaw, drive end and rod hinge connection, connecting rod offsets away from an end of jaw and the cam segment of cam lever, and cam segment is that radius becomes big curved surface gradually, and extension spring is connected compressing between end and the chuck body of cam lever.
