Abstract
The utility model relates to a soft claw used for a three jaw chuck. The soft claw is characterized by comprising three supporting blocks arranged on the three jaw chuck, wherein a mounting groove matched with the three claw chuck is arranged in the bottom of each supporting block, the supporting blocks are connected to the three claw chuck through bolts, locating grooves, which are vertical to each mounting groove, are formed in two sides of each mounting groove, the top surface of each supporting block is detachably connected to a clamping block for clamping a part, the shape of a clamping surface of each clamping block is matched with the shape of the corresponding part, and a chip containing groove is formed in one side, for clamping the corresponding part, of each supporting block. When the soft claw used for the three jaw chuck is used, the deflection of the parts can be reduced, the chip removal is easy and the different parts can be processed.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of soft claws for three-jaw chuck.
Background technology
The internal bore boring processing of large stroke thin-wall precise part is generally by the clamping of hydraulic pressure three-jaw, hydraulic center frame supplemental support on full function CNC turning machine in machine industry.Because the soft pawl of standard is thinner, shorter.When clamping, concentrate because of clamping stress point, part is yielding, and retaining part forms triangle.When clamping, part and chuck distance are too near, and boring adds the iron filings that produce man-hour cannot discharge, and endoporus is scratched, and affects surface roughness and the endoporus machining accuracy of endoporus.
Utility model content
For above-mentioned prior art, the utility model aims to provide a kind of soft claws for three-jaw chuck, and this soft claws for three-jaw chuck can reduce the deflection of part when in use, and chip removal is easy, and can process the part of different-diameter.
In order to achieve the above object, the technical solution of the utility model: a kind of soft claws for three-jaw chuck, it is characterized in that, comprise three back-up blocks that are arranged on scroll chuck, described back-up block bottom is provided with the mounting groove matching with scroll chuck, described back-up block and scroll chuck are connected by screw, described mounting groove both sides are provided with perpendicular locating slot, described back-up block end face is removably connected with the grip block of clamping part, clamping face and the part shape of described grip block match, and described back-up block is provided with chip pocket in that side of clamping part.
Further, described back-up block is connected by two bolts with grip block.
Further, described back-up block is notch cuttype.
Further, described locating slot is some zigzag slots.
The beneficial effects of the utility model: when adopting after the soft claws for three-jaw chuck of this structure, in clamping tube kind part, because clamping face and the part shape of grip block match, so can reduce the deflection of part, simultaneously, being arranged so that iron filings are discharged and preventing smoothly endoporus to scratch of chip pocket, this soft pawl, because grip block and back-up block removably connect, can be selected different grip blocks according to different accessory sizes and shape.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model stereogram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the left view of Fig. 2.
In figure: 1, locating slot; 2, chip pocket; 3, installing hole; 4, back-up block; 5, grip block; 6, clamping face; 7, mounting groove.
Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of soft claws for three-jaw chuck as Figure 1-3, comprise three back-up blocks 4 that are arranged on scroll chuck, described back-up block 4 bottoms are provided with the mounting groove 7 matching with scroll chuck, described back-up block 4 and scroll chuck are connected by screw, described mounting groove 7 both sides are provided with perpendicular locating slot 1, described back-up block 4 end faces are removably connected with the grip block 5 of clamping part, clamping face 6 and the part shape of described grip block 5 match, and described back-up block 4 is provided with chip pocket 2 in that side of clamping part.
When adopting after the soft claws for three-jaw chuck of this structure, in clamping part, owing to being provided with mounting groove 7 in back-up block 4 bottoms, accordingly, on scroll chuck, be provided with projection, described projection and mounting groove 7 match, before location, mounting groove 7 can slide along projection, when being adjusted to behind suitable position, locates by locating slot 1, concrete described locating slot 1 is zigzag locating slot 1, accordingly, on scroll chuck, be also provided with zigzag locating slot, after location completes, soft pawl be arranged on scroll chuck by two installing holes 3 on it.Because clamping face 6 and the part shape of grip block 5 match, so can reduce the deflection of part, grip block 5 as shown in Figure 1, be exclusively used in clamping tube kind part, meanwhile, the iron filings discharge that is arranged so that of chip pocket 2 prevents endoporus to scratch smoothly, this soft pawl is because grip block 5 and back-up block 4 removably connect, can select different grip block 5 according to different accessory sizes and shape, the shape difference of the clamping face 6 of different grip blocks 5, so can clamp different parts.
Be more preferably, described back-up block 4 is connected by two bolts with grip block 5.That is to say, damage or need to process after difform part at grip block 5, the just replaceable grip block 5 of directly bolt being back-outed.
Best, described back-up block 4 is notch cuttype.Back-up block 4 is arranged to notch cuttype, and this mode had both been saved material, did not also affect the use of soft pawl.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in detailed description of the invention and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
