Abstract
The utility model relates to a rapid clamping mechanism of a machine tool, in particular to a clamping mechanism for a machine tool, solving the problems that the traditional clamping mechanism for the machine tool must carry out multi-time clamping to accomplish processing, needs to be provided with a large number of cushion blocks with different heights, has time-wasting operation and easy generation of unevenness on the upper plane and the lower plane of a processed workpiece, and the like. The rapid clamping mechanism for machine tool comprises a T-shaped key, a fixed clamp and a movable clamp, wherein the T-shaped key is arranged in a T-shaped slot on a T-shaped worktable; the fixed clamp and the movable clamp come into contact with each other, and the mutually contact surfaces of the fixed clamp and the movable clamp are slopes and are in a dovetail slot fit; a hole is arranged on the mixed clamp, and a straight bolt in threaded connection with the T-shaped slot is arranged in the hole; and an inclined hole parallel to the mutually contact surfaces of the fixed clamp and the movable clamp is arranged on the movable clamp, and an inclined bolt in threaded connection with the T-shaped key is arranged in the inclined hole. The rapid clamping mechanism has compact structure, large clamping force, safety and firmness, and not only can reliably clamp workpieces, but also ensure that the bottoms of the workpieces and the T-shaped worktable tightly come into contact with each other, and has reliability and convenience.
Description
Technical field
The utility model relates to the clamp mechanism of lathe, is specially quick clamping mechanism for machine tool.
Background technology
The lathe clamp mechanism has very important effect in mechanical processing industry.Process all workpiece and all be unable to do without clamp mechanism.Clamp mechanism commonly used at present has spiral clamp mechanism and spiral presser type clamp mechanism.
Spiral presser type clamp mechanism (as shown in Figure 1): comprise that the lower end is positioned the screw rod 2 on the T type workbench 1, be placed in the pressing plate 3 on the screw rod 2, and the cushion block 5 between screw rod 2 nut engaged 4 and pressing plate and the workbench.It is to utilize nut to rotatably compress pressing plate, comes workpiece pressing by lever principle.When the shortcoming of spiral presser type clamp mechanism is (1) processing work 6, because the impetus of pressing plate just in time is to be processed 7 of workpiece 6, so must carry out multiple clamping to finish processing.More time-consuming.(2) add man-hour, the cushion block height is had certain requirement, the workpiece of different-thickness needs the cushion block of differing heights.Need to be equipped with the cushion block of a large amount of differing heights.When (3) compressing, need that nut is screwed into the appropriate location and screw the nut workpiece pressing then, more time-consuming.
Spiral clamp mechanism (as shown in Figure 2): comprise that the lower end is positioned the gag 9 on the T type workbench 8, level pass gag and with the screw rod 10 of gag threaded engagement.It comes clamping work pieces by rotary screw 10.The shortcoming of spiral clamp mechanism is: because clamping force is parallel to T type workbench, so the workpiece lower plane can not closely contact with T type workbench, cause on the workpiece of processing back lower plane not parallel easily.
Summary of the invention
The utility model provides a kind of quick clamping mechanism for machine tool in order to solve existing lathe with defective and problem that clamp mechanism exists.This clamp mechanism only needs a clamping to get final product, and does not need cushion block, and is simple to operate, save time, and can guarantee the accurate location of workpiece on workbench.
The utility model is to adopt following technical scheme to realize: quick clamping mechanism for machine tool, comprise the T type key in the T type groove that places on the T type workbench, geometrical clamp that is in contact with one another and live splint, the face that is in contact with one another of geometrical clamp and live splint is the inclined-plane and is dovetail groove cooperation (being that being in contact with one another of geometrical clamp and live splint has dovetail and the dovetail groove that is fitted to each other on the face), have the hole on the geometrical clamp, the straight bolt that is threaded with T type key is arranged in the hole, have the parallel inclined hole of the face that is in contact with one another with geometrical clamp and live splint on the live splint, the oblique bolt that is threaded with T type key is arranged in the inclined hole.During use, use two groups of these quick clamping mechanism for machine tool at least, to realize clamping to workpiece.Earlier T type key is packed in the T type groove of T type workbench, about workpiece is placed between " quick clamping mechanism for machine tool ", the another side (promptly relative with inclined-plane face) of limit, left and right sides live splint is contacted (according to the shape of workpiece with face about workpiece, the live splint another side can be inclined-plane or vertical plane), tighten straight bolt in the geometrical clamp then, thereby geometrical clamp is pressed on the workbench and realizes its location, again the oblique bolt in the live splint of left and right sides mechanism is tightened, in the rundown process of oblique bolt, live splint along dovetail groove to lower slider, thereby workpiece is exerted pressure, finish clamping workpiece.
Quick clamping mechanism for machine tool structural design novelty described in the utility model, reasonable, compact conformation, by tightening oblique bolt, live splint slides along the inclined-plane dovetail groove, the clamping force that produces is big and safety is firm, reliable holding workpiece not only, and workpiece bottom is closely contacted with T type workbench, reliable, convenient.Overcome the deficiency that existing clamp mechanism exists, clamp mechanism only needs the processing that clamping can be finished workpiece, does not need cushion block, and is simple to operate, save time, and can guarantee the accurate location of workpiece on workbench.

The specific embodiment
Quick clamping mechanism for machine tool, comprise the T type key 12 in the T type groove that places on the T type workbench 11, geometrical clamp 13 that is in contact with one another and live splint 14, the face that is in contact with one another of geometrical clamp 13 and live splint 14 is the inclined-plane and is dovetail groove cooperation (being that being in contact with one another of geometrical clamp and live splint has dovetail and the dovetail groove that is fitted to each other on the face), have the hole on the geometrical clamp 13, the straight bolt 15 that is threaded with T type key 12 is arranged in the hole, have the parallel inclined hole of the face that is in contact with one another with geometrical clamp and live splint on the live splint 14, the oblique bolt 16 that is threaded with T type key 12 is arranged in the inclined hole.During concrete enforcement, for optimizing mechanical structure, the face that is in contact with one another of geometrical clamp 13 and live splint 14 is the inclined-plane that is 40 ° of-60 ° of angles with T type workbench.Tiltedly be with the spring 17 that is pressed between live splint and the T type key on the bolt 16, spring can prevent that oblique bolt 16 from becoming flexible, and when dismounting, the elastic force of spring is convenient to the dismounting of live splint simultaneously.Inclined hole on hole on the geometrical clamp 13 and the live splint 14 all is a counterbore.
