Abstract

The invention discloses a cam clamping device which comprises a clamping device, a force applying device and a reset device. The clamping device comprises an elastic clamping sleeve and a clamping jaw, wherein the elastic clamping sleeve clamps workpieces from the inner portion, and the clamping jaw clamps the workpieces from the outer portion. An extruding sleeve is arranged at the outer portion of the elastic clamping sleeve. The force applying device comprises a force applying handle which is fixedly connected with a cam. The elastic clamping sleeve is connected with the inner side of the cam in a threaded mode. The outer side of the cam contacts with a drive end of the clamping jaw. The clamping jaw is fixed on a support through a hinge joint point. A driven end of the clamping jaw is a clamping head of a clamping workpiece. A reset spring of the clamping jaw is arranged on the support. The force applying handle is rotated to enable the ram to rotate. The elastic clamping sleeve is connected with the inner side of the cam in the threaded mode to drive the elastic clamping sleeve to move down. Due to the fact that the extruding sleeve is arranged at the outer portion of the elastic clamping sleeve, the elastic clamping sleeve clamps the workpieces from the inner portion. Meanwhile, the outer side of the cam contacts with the drive end of the clamping jaw to drive the clamping jaw to clamp the workpieces from the outer portion, and thereby the workpieces are achieved to be clamped from the inner portion and the outer portion through the cam.

Description

The cam clamping device
Technical field
The present invention relates to a kind of fixture for processing, be specifically related to a kind of cam clamping device.
Background technology
Fixture is used for fixing processing object in the machine-building process, make it to occupy correct position, with the device of accepting construction or detecting.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, for the surface that makes workpiece can reach the drawing regulation size, geometry and with other surperficial specification requirements such as relative-position error, workpiece must be located, clamp before processing.Some workpiece needs to clamp simultaneously with the outside internally due to the particularity of its structure, thereby needs a kind of special cam clamping device.
Summary of the invention
The object of the present invention is to provide a kind of cam clamping device, solve the problem that workpiece clamps simultaneously with the outside internally.
For achieving the above object, technical scheme of the present invention is: the cam clamping device, comprise clamping device, force application apparatus and resetting means, described clamping device comprises the elastic jacket of clamping work pieces internally and from the jaw of outside clamping work pieces, the outside of described elastic jacket is provided with extruded sleeve; Described force application apparatus comprises an application of force handle, application of force handle is fixedly connected with cam, described cam inside thread connects elastic jacket, the described cam outside contacts with the drive end of jaw, described jaw is fixed on bearing by pin joint, the driven end of jaw is the chuck of clamping work pieces, and bearing is provided with the back-moving spring of jaw.
When adopting technique scheme, by the rotation urging handle, rotating cam because the cam inside thread connects elastic jacket, drives elastic jacket and moves down, because the outside of elastic jacket is provided with extruded sleeve, so elastic jacket is clamping work pieces internally, simultaneously, the outside of cam contacts with the drive end of jaw, drive jaw from outside clamping work pieces, realized by the inside and outside clamping of cam to workpiece.
Further, described elastic jacket surface arranges left hand thread.Facilitate elastic jacket clamping work pieces internally.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of cam clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, cam clamping device of the present invention comprises clamping device, force application apparatus and resetting means, and described clamping device comprises the elastic jacket 1 of clamping work pieces internally and from the jaw 2 of outside clamping work pieces, the outer setting extruded sleeve 11 of elastic jacket 1; Force application apparatus comprises an application of force handle 3, application of force handle 3 is fixedly connected with cam 4, cam 4 inside threads connect elastic jacket 1, the drive end 21 of cam 4 outsides and jaw 2 contacts, jaw 2 is fixed on bearing 5 by pin joint, the driven end 22 of jaw 2 is the chuck of clamping work pieces, and bearing 5 is provided with the back-moving spring 51 of jaw.
By rotation urging handle 3, rotating cam 4 because cam 4 inside threads connect elastic jackets 1, drives elastic jacket 1 and moves down, because the outer cover of elastic jacket 1 has extruded sleeve 11, so elastic jacket 1 clamping work pieces internally.Simultaneously, the drive end 21 of the outside of cam 4 and jaw 2 contacts, and drives jaw 2 from outside clamping work pieces, has realized clamping by the inside and outside of 4 pairs of workpiece of cam.
Above-described is only the 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)
