Abstract

The invention discloses a multi-wedge-face sliding type clamping mechanism which is simple in structure and easy and convenient to operate. The multi-wedge-face sliding type clamping mechanism comprises a base, two or more wedges and a pressing pipe. The section of the base is a U-type groove, and a round hole is formed in the center of the bottom face of the base. The wedges are connected with the side walls of the base through springs. A cylinder is arranged at the upper end of the pressing pipe, and the lower end of the pressing pipe is inserted in the round hole in the center of the base. The bottom faces of the wedges are arc faces, a round hole is formed in the position, close to the bottom end, of each wedge, and the wedges are fixed to the bottom end of the base by the round holes through locating pins. According to the scheme, the multi-wedge-face sliding type clamping mechanism has the beneficial effects that the effect of clamping workpieces is achieved through simple operation, and the structure is simple.

Description

Many cammed surface slidingtype clamp system
Technical field
The present invention relates to a kind of oblique-wedge clamping system, be specifically related to a kind of many cammed surface slidingtype clamp system.
Background technology
In the past few years, the product of Multi-varieties and Small-batch Production grows with each passing day, and as the technological equipment that manufacturing industry is indispensable, the flexibility of jig, greenization become a Main way of modern fixture.Fixture in the past adopts mode manually often, but the disadvantage of manual fixture is exactly the restriction by staff effect, and clamp power is less, constrains the scope of application of manual,
In order to save the labour intensity of user, oblique-wedge clamping system has occurred as one of a kind of clamping device form the most basic in present Machine Tool Fixture Design.Oblique-wedge clamping system by wedge and slide block with the use of, the power clamping work pieces produced when utilizing inclined-plane to move, become and move both vertically as horizontal movement or banking motion, not only save the labour intensity of user, the sleeve workpiece within the scope of certain size can also be processed.
In prior art, in patent document CN203751955U, disclose a kind of oblique-wedge clamping system, comprise mandrel, back-moving spring, wedge, wedge fairlead, briquetting, open washer and nut composition.Fastening nut, open washer and briquetting move, and move along the uniform gathering sill of circumference on voussoir fairlead with making wedge constant speed, wedge is along the outside constant speed movement of radial direction of voussoir fairlead simultaneously, realizes the location to workpiece and clamping.After workpiece completes the grinding of cylindrical, loosening nut, rely on the elastic force of back-moving spring promotion wedge to move along the gathering sill of voussoir fairlead, workpiece is released, can realize freely loading and unloading of workpiece.
But this clamp system is more complicated, and wherein nut element is in use easily killed, after having grown service time once screw thread due to stressed have point deformation after nut will be caused to twist not get off, impact uses.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide many cammed surface slidingtype clamping mechanism that a kind of structure simple operations is easy.
For making structure simple, base case of the present invention is: many cammed surface slidingtype clamp system, comprise pedestal, more than two pieces wedges, pressure pipe, described pedestal section is U-type groove, the bottom center of described pedestal has a hole, described wedge is connected by the sidewall of spring with described pedestal, described pressure pipe upper end is round platform, and described pressure pipe lower end is inserted in the circular hole of described base central, and described wedge bottom is an arc surface, described wedge has a circular hole near bottom, and described wedge is fixed on the bottom of described pedestal by described circular hole by alignment pin.
Adopt above-mentioned base case, moving upward by pressure pipe, be converted into wedge and rotate outwardly, make wedge and absorption surface thus realize clamping the location of workpiece, pressure pipe moves downward, and wedge rotates inwardly, is separated unclamps workpiece with workpiece.Compared with the structure of prior art, this programme can reach the object of clamping by means of only the common part such as spring, steady pin, and structure is simpler.And compared with the operation of prior art, this programme realizes clamping to workpiece by sliding up and down of pressure pipe, operates easier.
Preferred version one: based on the preferred version of scheme, the contact surface of described wedge and described pressure pipe is that circular arc is protruding, arc surface can increase the contact area of wedge and pressure pipe, reduces the pressure in pressure pipe unit are to greatest extent, thus makes the slip of pressure pipe more laborsaving.
Preferred version two: based on the preferred version of scheme or preferred version one, the one side of described wedge and absorption surface is embedded with the claw of one side for serrated face, the serrated face of described claw is the one side with absorption surface, serrated face increases friction between the two, can better clamp workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the schematic diagram of a kind of oblique-wedge clamping system in prior art.
Mark implication in accompanying drawing 1: 1-wedge, 2-spring, 3-pressure pipe, 4-alignment pin, 5-claw.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As shown in Figure 1, a kind of many cammed surface slidingtype clamp system is provided in the present embodiment, comprise pedestal, more than two pieces wedges, pressure pipe, described pedestal section is U-type groove, the bottom center of described pedestal is provided with a circular hole, described wedge 1 is connected with the sidewall of described pedestal by spring 2, described pressure pipe 3 upper end is cylinder, and described pressure pipe 3 lower end is inserted in the circular hole of described base central, and described wedge 1 bottom surface is an arc surface, described wedge 1 has a circular hole near bottom, and described wedge is fixed on the bottom of described pedestal by described circular hole by alignment pin 4.Under normality, wedge 5 is in inversion state due to the effect of spring 2.Upwardly pressure pipe 3, pressure pipe 3 contacts with wedge 1, wedge 1 is made to be that the center of circle circles with alignment pin outwardly, make the serrated face of claw 5 and the contact internal walls of workpiece, move along with in pressure pipe 3, claw 5 increases gradually with the power suffered by contact surface of workpiece, realize the clamping to workpiece, the pressure now receiving wedge due to spring 2 is in compressive state, thus gives wedge 1 one reverse elastic force, makes wedge 1 compress pressure pipe 2.Move down pressure pipe 3, claw 5 reduces with the power suffered by contact surface of workpiece, and now because spring 2 receives the pressure reduction of wedge, spring 2 starts to reply, to wedge 2 one pressure.Along with moving down of pressure pipe 2, wedge 1 and pressure pipe 2 disengage, and wedge 1 answers reset condition next time at the pressure of gravity and spring 2 this moment.
