Description

The fixture of strap cam

Technical field

The present invention relates to a kind of machine tool component, be specifically related to a kind of fixture of strap cam.

Background technology

In mechanical processing process, usually need first workpiece to be fixed by clamping device, make workpiece obtain the tram with respect to lathe and cutter, then workpiece is processed.By clamping device, workpiece is fixed, because the positional precision of workpiece is guaranteed by clamping device, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and stable, and then the rate of reducing the number of rejects and seconds, guaranteed the quality of product; Because clamping device can make workpiece location and clamping rapidly, reduce unproductive time significantly again, improved production efficiency.So both can guarantee mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce the excessive demand to workman's technology again.

Because processing needs, some workpiece will fix by hand actuable clamping device conventionally.But some hand actuable clamping devices can only be gradually by Workpiece clamping, and efficiency is not high, use inconvenience.

Summary of the invention

The technical problem to be solved in the present invention comprises: the fixture that a kind of easy to use and strap cam that operating efficiency is high is provided.

In order to solve the problems of the technologies described above, the invention provides a kind of fixture of strap cam, comprise workbench and pressing plate, described workbench one end and cam are hinged, and the other end is provided with groove, and workbench middle part is fixedly connected with support; Described pressing plate middle part is hinged with support, and one end of pressing plate and cam offset, and the other end is provided with briquetting; Along with cam rotates, pressing plate two ends in the vertical direction moves reciprocatingly.

Adopt after such structure, because one end of cam and pressing plate offsets, along with cam rotates, one end in the vertical direction that pressing plate contacts with cam moves reciprocatingly, by lever principle, can make the pressing plate other end swing up and down, and then workpiece is unclamped or grip.Easy to use and operating efficiency is high.

As preferred version, between briquetting and pressing plate for removably connecting.Adopt after such structure, the briquetting of replaceable different structure, is better fixed the workpiece of revolving body workpieces or cube structure.

As preferred version, one end that described pressing plate and cam offset is hinged with roller.Adopt after such structure, when cam is contacted with pressing plate, frictional force is less.

As preferred version, one end that described briquetting contacts with workpiece is provided with rubber antiskid pad.Adopt after such structure, because rubber antiskid is lined with certain elasticity, can prevent that briquetting from causing damage to surface of the work in the process of fixation workpiece.

Accompanying drawing explanation

Fig. 1 is the structural representation of the fixture embodiment of strap cam of the present invention.

the specific embodiment

For sake of convenience, hereinafter alleged " on ", D score, " left side ", " right side " respectively, left upper and lower, right with accompanying drawing 1 itself to consistent, but structure of the present invention is not played to restriction effect.

Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:

The fixture of strap cam as shown in Figure 1, comprises workbench 6 and pressing plate 3, and described workbench 6 right-hand members and cam 5 are hinged, and left end is provided with groove, and workbench 6 middle parts are fixedly connected with support 2; Described pressing plate 3 middle parts and support 2 are hinged, and the right-hand member of pressing plate 3 and roller 4 hinged, roller 4 offsets with cam 5, pressing plate 3 left ends are provided with briquetting 1; Between briquetting 1 and pressing plate 3, for removably connecting, one end that briquetting 1 contacts with workpiece is provided with rubber antiskid pad.Along with cam 5 rotates, pressing plate 3 two ends in the vertical directions move reciprocatingly.

During use, first revolving body workpieces is placed on the groove of briquetting 1 below workbench 6, rotating cam 5, moves up pressing plate 3 right-hand members, and simultaneously briquetting 1 moves down and by Workpiece clamping.At this moment, just can process workpiece.After to be processed completing, rotating cam 5, moves down pressing plate 3 right-hand members, and briquetting 1 moves up and workpiece is unclamped simultaneously.

For the workpiece of cube structure, before use, first on workbench 6, place backing plate and change briquetting 1, the workpiece of cube structure is placed on the workbench 6 of briquetting 1 below, rotating cam 5, moves up pressing plate 3 right-hand members, and simultaneously briquetting 1 moves down and by Workpiece clamping.At this moment, just can process workpiece.After to be processed completing, rotating cam 5, moves down pressing plate 3 right-hand members, and briquetting 1 moves up and workpiece is unclamped simultaneously.

Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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.
