Abstract

The invention discloses an eccentric threaded cam clamping device which comprises an eccentric threaded cam, a base, a spline shaft, a control handle, a working table, a locating stop block and a drilling guide sleeve. The eccentric threaded cam is screwed with the base, the spline shaft is matched with the control handle and the eccentric threaded cam simultaneously to conduct transmission, the working table is arranged on the left side of the base, the workpiece locating stop block is arranged at the front end of the working table, and the drilling guide sleeve is arranged on a workpiece. The eccentric threaded cam clamping device has the advantages of being high in efficiency, reliable in clamping, convenient to use, high in safety and the like.

Description

A kind of eccentric screw thread cam clamping device
Technical field
The present invention relates to the mechanical clamp technical field, particularly relate to a kind of eccentric screw thread cam clamping device.
Background technology
Usually the anchor clamps on the drilling machine are varied, the principle of the use hydraulic pressure that has, the principle of the use theory of mechanisms that has.The principle of hydraulic pressure need have the special device that pressure oil can be provided, and wastes energy.Use the principle of theory of mechanisms, design special mechanism, complex structure.
Summary of the invention
The invention provides a kind of solution of the above problems, a kind of easy to use, eccentric screw thread cam clamping device efficiently is provided.
Technical problem to be solved by this invention is a kind of eccentric screw thread cam clamping device efficiently of designing at above-mentioned needs of the prior art, workpiece is placed on the workbench, the eccentric screw thread cam on its right side clockwise rotates clamping work pieces, rotates counterclockwise and then loosens workpiece.
Described eccentric screw thread cam is left hand thread.
The thread form of screw thread is triangle on the described eccentric screw thread cam.
All be processed with spline on described control crank center and the eccentric screw thread cam.
The left side of described base is an inclined-plane.
The right of described workbench is an inclined-plane.
The right flank of described boring guide pin bushing can not exceed the right flank of workpiece.
Owing to adopted as above technical scheme, the present invention has following characteristics: simple in structure, efficient height, reliable clamping, property easy to use, safe are good.
Description of drawings
Fig. 1 is the eccentric screw thread cam of the present invention clamping device structure chart.
Fig. 2 is that splined shaft A is to view.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the present invention is a kind of eccentric screw thread cam clamping device, mainly include eccentric screw thread cam 1, base 2, splined shaft 3, control crank 4, workbench 5, position block 6, boring guide pin bushing 8, eccentric screw thread cam 1 screws with base 2, splined shaft 3 cooperates transmission with control crank 4 and eccentric screw thread cam 1 simultaneously, workbench 5 is positioned at the left side of base 2, and its front end has been installed workpiece position block 6, is provided with boring guide pin bushing 8 above the workpiece 7.
Screw thread on the eccentric screw thread cam 1 is left hand thread, clockwise rotates clamping work pieces, rotates counterclockwise and then loosens workpiece.
The thread form of screw thread is triangle on the eccentric screw thread cam 1, because the triangle thread self-locking performance is good, screw thread is in self-locking, reliable clamping in the time of can guaranteeing the workpiece clamping like this.
The center of control crank 4 and eccentric screw thread cam 1 upper end all are processed with spline, cooperate with splined shaft 3 simultaneously, and rotation control crank 4, then eccentric screw thread cam 1 plays rotation with one.
The left side of base 2 is an inclined-plane, and the right of workbench 5 is an inclined-plane, can guarantee fully workpiece pressing 7 of eccentric screw thread cam 1 like this.
The right flank of boring guide pin bushing 8 than the right flank indentation of workpiece 7 some, can guarantee that so eccentric screw thread cam 1 can not interfere with boring guide pin bushing 8 during workpiece pressing 7.
Above embodiment only is the present invention's a kind of embodiment wherein; but can not therefore be interpreted as the restriction to claim of the present invention; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
