Abstract
The invention 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; 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 clamping device is ingenious in structural design, and compared with the existing clamping device, the clamping device 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 present invention relates to a kind of clamping device, be 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, usually adopt artificial free-hand finishing in order to reduce cost, by utilizing lever, spring, pulley, cam, the combinations such as jaw reach the effect of clamping work pieces.Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, when artificial hand operation, there are all multioperation inconvenience, the inconvenient application of force, can't suitably grasp the problem such as anchor clamps clamping dynamics.
Summary of the invention
The object of the present invention is to provide a kind of easy to operately, laborsaving, and have a kind of cam clamping device that to grasp anchor clamps clamping dynamics.
The present invention is achieved by 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, left jaw middle part is fixedly connected with chuck body, 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 invention has the beneficial effects as follows:
Structural design of the present invention is ingenious, rotation crank band moving 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.Bar hole on its 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 present invention is not only easy to operate, laborsaving; The use of cam indirectly held the clamping dynamics of anchor clamps, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
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, left jaw 2 middle parts are fixedly connected with chuck body 1, 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 band moving cams 4, 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.Bar hole 5 and alignment pin 6 matched in clearance on its right jaw 3 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 invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
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, left jaw middle part is fixedly connected with chuck body, 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.
2. a kind of cam clamping device as claimed in claim 1, it is characterized in that: described cam is provided with rocking handle.
