Abstract
The utility model discloses a clamping device, in particular to a cam clamping device, which comprises a clamp body, a left clamping jaw, a right clamping jaw and a cam, wherein the left clamping jaw and the right clamping jaw are used for clamping a workpiece, and the cam is positioned in the middle of the clamping jaw and is used as a force application device; the lower parts of the left clamping jaw and the right clamping jaw are hinged on the clamp body; the middle part of the left clamping jaw is fixedly connected with the clamp body, the middle part of the right clamping jaw is provided with a strip-shaped hole, a positioning pin is arranged in the strip-shaped hole and fixedly arranged on the clamp body, and a return spring is arranged between the left clamping jaw and the right clamping jaw; the cam is hinged on the clamp body and is abutted against the middle parts of the left clamping jaw and the right clamping jaw; the utility model has ingenious structural design, and compared with the existing clamping device, the utility model is convenient to operate and labor-saving; the clamping force of the clamp is indirectly controlled by using the cam, and the cost is low.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of cam 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 are all multioperation inconvenience, the inconvenient application of force, can't suitably grasp problems such as anchor clamps clamping dynamics.
The utility model content
It is a kind of easy to operate, laborsaving that the purpose of this utility model is to provide, and have a kind of cam clamping device that can grasp anchor clamps clamping dynamics.
The utility model is achieved through the following technical solutions:
A kind of cam clamping device, comprise chuck body, be used for clamping work pieces left and right jaw, be positioned at the jaw middle part and as the cam of force application apparatus; Described left and right jaw lower hinge is on chuck body; Wherein, fixedly connected with chuck body in left jaw middle part, and right jaw middle part has bar hole, is provided with alignment pin in the bar hole, and described alignment pin is installed on the chuck body, is provided with back-moving spring between the left and right jaw; Described cam is hinged on the chuck body and with left and right jaw middle part and offsets.
Further, convenient for the application of force, described cam is provided with rocking handle.
The beneficial effects of the utility model are:
The utility model structural design is ingenious, and rotation crank drives cam, and the extruding between cam and the jaw forces right jaw to expand outwardly, and clamps workpiece under the cooperation of left jaw and right jaw.Wherein the bar hole on the right jaw and alignment pin matched in clearance play position-limiting action, and when workpiece was removed, back-moving spring played reset response to right jaw.Compare with existing clamping device, the utility model is not only easy to operate, laborsaving; The use of cam, indirect assurance the clamping dynamics of anchor clamps, and cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
By reference to the accompanying drawings shown in 1, a kind of cam clamping device, comprise chuck body 1, be used for clamping work pieces left jaw 2 and right jaw 3, be positioned at left jaw 2 and right jaw 3 middle parts and as the cam 4 of force application apparatus; Described left jaw 2 and right jaw 3 lower hinge are on chuck body 1; Wherein, fixedly connected with chuck body 1 in left jaw 2 middle parts, can adopt screw or bolt to connect, right jaw 3 middle parts have bar hole 5, be provided with alignment pin 6 in the bar hole 5, described alignment pin 6 is installed on the chuck body 1, is provided with back-moving spring 7 between left jaw 2 and the right jaw 3; Described cam 4 is hinged on the chuck body 1 and with left jaw 2 and right jaw 3 middle parts and offsets, and cam 4 is provided with rocking handle 8.
During use, rotation crank 8 drives cams 4, and the extruding between cam 4 and left jaw 2 and the right jaw 3 forces right jaw 3 to expand outwardly, and clamps workpiece under the cooperation of left jaw 2 and right jaw 3.Wherein the bar hole on the right jaw 35 and alignment pin 6 matched in clearance play position-limiting action, when workpiece is removed, and 3 reset responses of 7 pairs of right jaws of back-moving spring.
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 (2)
1. cam clamping device, comprise chuck body, be used for clamping work pieces left and right jaw, be positioned at the jaw middle part and as the cam of force application apparatus; It is characterized in that: described left and right jaw lower hinge is on chuck body; Wherein, fixedly connected with chuck body in left jaw middle part, and right jaw middle part has bar hole, is provided with alignment pin in the bar hole, and described alignment pin is installed on the chuck body, is provided with back-moving spring between the left and right jaw; Described cam is hinged on the chuck body and with left and right jaw middle part and offsets.
