Abstract

The utility model discloses a clamping device, in particular to a thrust clamping device. The thrust clamping device comprises a clamp body, a pushing rod used for pressing a lateral face of a workpiece and a cam located on the clamp body to serve as a force exerting device. A through hole is transversely formed in the clamp body, the pushing rod penetrates through the through hole to abut against the lateral face of the workpiece, a cambered surface matched with the cam is arranged at the tail portion of the pushing rod, a spiral groove is formed in the cambered surface, a location pin corresponding to the spiral groove is arranged on the cam, and a handle is fixedly arranged on the cam further. The clamping device is ingenious in structural design, and the handle is rotated and the location pin is in sliding fit with the spiral groove to drive the pushing rod to move in the horizontal direction to accordingly clamp or release the workpiece. Compared with the prior art, the thrust clamping device is convenient to operate, saves labor and can master clamping force of the clamp.

Description

A kind of thrust clamping device
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of thrust clamping device.
Background technology
Anchor clamps and grip device are widely known by the people, and are widely used for manufacturing.Particularly, anchor clamps have various reference surfaces and/or point, and parts or instrument can accurately be located.In many process, be general to clamp member, so that these parts can keep correct juxtaposition relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying.
For location and the clamping of miniature workpiece, adopt artificial free-hand finishing in order usually to reduce cost, by utilizing lever, spring, pulley, cam, compound modes such as jaw reach the effect of clamping work pieces.Though existing clamping device can satisfy the clamping demand of workpiece to a certain extent, when artificial free-hand operation, there is application of force inconvenience, can't accurately hold jaw clamping dynamics.
The utility model content
The purpose of this utility model is to provide a kind of thrust clamping device, and is easy to operate, laborsaving, and can grasp anchor clamps clamping dynamics.
The utility model is achieved through the following technical solutions:
A kind of thrust clamping device, comprise chuck body, be used for the workpiece pressing side push rod, be positioned on the chuck body cam as force application apparatus; Laterally have through hole on the chuck body, described push rod passes described through hole and offsets with the side of workpiece, and the afterbody of push rod is provided with the cambered surface that adapts with cam, is provided with helicla flute in the cambered surface, cam is provided with the alignment pin corresponding with helicla flute, also is installed with handle on the cam.
The beneficial effects of the utility model are:
The utility model structural design is ingenious, turning handle, and alignment pin and spiral fluted are slidingly matched, and drive push rod movement in the horizontal direction, thereby realize the clamping of workpiece or loosen.Compared with prior art, the utility model is easy to operate, laborsaving, and can grasp anchor clamps clamping dynamics.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 uses push rod plan structure schematic diagram among novel Fig. 1 for this
Fig. 3 uses push rod left view among novel Fig. 2 for this.
The specific embodiment
By reference to the accompanying drawings shown in 1,2,3, a kind of thrust clamping device, comprise chuck body 1, be used for workpiece pressing 2 sides push rod 3, be positioned on the chuck body 1 cam 4 as force application apparatus; Laterally have through hole 5 on the chuck body 1, described push rod 3 passes described through hole 5 and offsets with the side of workpiece 2, and the afterbody of push rod 3 is provided with the cambered surface that adapts with cam 4, is provided with helicla flute 6 in the cambered surface, cam 4 is provided with the alignment pin 7 corresponding with helicla flute 6, also is installed with handle 8 on the cam 4.
Turning handle 8, alignment pin 7 is slidingly matched with helicla flute 6, drives push rod 3 movement in the horizontal direction, thereby realizes the clamping of workpiece 2 or loosen.
Above-described only is preferred embodiment of the present utility model; should be understood that; 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 (1)
