Description
Technical field
The utility model relates to a kind of clamping device, especially relates to a kind of quick clamping mechanism.
Background technology
It is to use wider clamp mechanism that spiral clamps, simple in structure, uses reliable.When the workpiece of required clamping is the close workpiece of size, then only need put workpiece, rotate a few again and make workpiece step up to get final product; After accomplishing processing, again counter-rotation a few can withdraw from workpiece because the size of folded workpiece is close; The number of turns of therefore rotating need not be too many, but when the workpiece that needs to clamp different size, and workpiece is when needing frequently alternately clamp; The number of turns that needs to rotate just increases greatly, causes wasting time and energy and inefficiency.
For example, Chinese patent Granted publication number: CN201128117Y, October 8 2008 Granted publication day; Disclose a kind of big stroke spiral fast fixture, wherein clamp mechanism is made up of clamping screw and guide pin bushing, and clamping screw is provided with helicla flute and axial groove; Be dovetail groove or U-lag, and deep equality, the slick and sly connection; Guide pin bushing is provided with radially ball stud, and the ball stud head stretches in helicla flute or the axial groove, and the clamping bar head is provided with briquetting and locking nut.Its weak point is only to be applicable to that big stroke clamps occasion according to the size adjustment stroke of clamping work pieces.
The utility model content
The utility model is for the clamping device that overcomes prior art can not only be applicable to that big stroke clamps occasion according to the size adjustment stroke of clamping work pieces, is not suitable for the deficiency of the workpiece that clamps different size, provide a kind of can
Quick clamping mechanism according to workpiece size size adjustment stroke.
To achieve these goals, the utility model adopts following technical scheme:
A kind of quick clamping mechanism of the utility model comprises mount pad and is located at the bearing on the mount pad, also comprises sliding axle; Described bearing upper end is fixedly connected with guide pin bushing, and described guide pin bushing is provided with chute, and chute is provided with some pin draw-in grooves; Also be provided with the pin that cooperates with the pin draw-in groove in the chute, described pin bottom is fixedly connected with sliding axle, described sliding axle and guide pin bushing socket; Also be provided with the axle of tightening that is threaded with it in the described sliding axle; Described axle one end of tightening is provided with and tightens handle, and the other end is provided with mobile briquetting, and described mount pad is provided with and the mobile briquetting briquetting that is relatively fixed.Guide pin bushing and sliding axle socket make that sliding axle can be along the slip of guide pin bushing front and back, and ten minutes is steady during the not only laborsaving convenience of adjusting ten minutes, and slip, good stability; Tighten axle and be threaded, make and tighten axle and also can move forward and backward, tighten a spool end and be provided with and tighten handle through rotation with sliding axle; Tighten handle and be convenient to tighten the rotation of axle; Tighten an other end and be provided with mobile briquetting, move briquetting through tightening the rotation of axle, cooperate clamping work pieces with fixing briquetting; Pin can slide with sliding axle, and the existing guide effect of chute has position-limiting action again, and sliding axle can not rotated in sliding process; Pin can push in the pin draw-in groove, is clockwise rotating when tightening the axis clamping workpiece, and sliding axle can not rotate thereupon, can be earlier according to the size push-and-pull sliding axle of required clamping work pieces; Pin is slipped in the different pin draw-in grooves, makes to move between briquetting and the workpiece to have the shortest initial distance, again through tighten handle rotate tighten axle make move briquetting and fixedly briquetting workpiece is stepped up to get final product; Easy to operate, clamp rapidly, be applicable to the workpiece of different size; Take out workpiece, unclamp mobile briquetting earlier, again with pin from stopper slot along withdrawing from the pin draw-in groove; Move sliding axle outward, can not interfere, take out workpiece again and get final product with sliding axle until workpiece.
As preferably, the opening part of described pin draw-in groove is provided with tapering, and the top of pin draw-in groove is provided with stopper slot.Opening part is provided with tapering and is convenient to pin and slips in the pin draw-in groove, and stopper slot can be shelved pin, can guarantee to tighten axle in rundown process, and pin can not withdraw from the pin draw-in groove.
As preferably, described sliding axle is provided with drawing handle near an end of tightening handle.Drawing handle is convenient to the slip of guide pin bushing, avoids the use of to tighten handle push-and-pull guide pin bushing, makes the thread damage of tightening between axle and the sliding axle.
Therefore, the utlity model has following beneficial effect:
(1) can be according to workpiece size size adjustment stroke, clamping work pieces fast;
(2) simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
