Abstract
The utility model provides a workblank self-centering clamp for manufacturing an all-electric injection molding machine. According to the workblank self-centering clamp, a novel positioning method is adopted, wherein a positioning surface of a workblank is changed from one surface on the outer side into two surfaces on the inner side so as to realize centering, namely positioning and centering are carried out by using one surface which is located in the same plane as a surface to be machined as a reference datum. A positioning and centering unit is installed on the clamp, wherein the center of the positioning and centering unit is fixed. A drive screw is rotated manually to make a reset spring reset. Two positioning surfaces of the workblank are clamped by two grippers, wherein the size of an opening formed by the grippers can be changed; in this way, a floating benchmark prop is formed by the two grippers and can change along with changes in the workblank, and one axial direction of the workblank can also be positioned to a fixed center along with the grippers. By the adoption of the clamp, influence on the finish size by uneven allowance and structural deformation of the workblank can be effectively reduced, and clamping time is shortened. Compared with the previous positioning modes, the workblank self-centering clamp lowers the reject rate of products, improves the quality stability of the products, and is easy, fast and effortless to operate.
Description
Technical field
The utility model belongs to machine components spray manufacture field, relates in particular to a kind of manufacture full electric injection molding machine self-centering blank fixture.
Background technology
Chaining part is the important spare part in injection machine, and its machining accuracy has very large impact for the accurate operation of injection machine.Fig. 1-3 provide the structural representation of chaining part blank.According to the front view of Fig. 1, three-dimensional localization is carried out in space, getting is laterally X-axis, is longitudinally Y-axis, and entering paper direction is Z axis, can describe each face of chaining part.As Figure 1-3, the face that chaining part has comprises inner side datum level A 1, inner side datum level B 2, Z-direction datum level A 3, Z-direction datum level B 4, X-direction datum level A 7, X-direction datum level B 8, Y-direction datum level A 9 and Y-direction datum level B 10.Foundry goods has to be processed A 5 and to be processed B 6, and the machining accuracy of these two faces will affect coordinating of chaining part and other drive disk assembly in injection machine, so the machining accuracy of these two faces is determining the processing quality of chaining part.
For the processing of blank, generally use horizontal Machining centers to carry out, that is, first foundry goods is assemblied on fixture, fixture is installed on workbench, start cutter part is processed.Therefore, the location of blank on fixture becomes the greatest factor that affects machining accuracy.At present, the locate mode for injection machine part chaining part on fixture is: by a side of blank, be close to positioning anchor, then push up and roll over from the point-to-point mode of contrary face, product is completed to an axial restriction.But due to blank dimension, may there is the phenomenons such as the inhomogeneous or malformation of surplus, will make like this some faces can't process, or the distance of blank and two machined surfaces be inhomogeneous.For preventing the appearance of this phenomenon, operating personnel may still will measure and confirm that whether allowance enough behind location, will be how the step work of proofreading and correct again, also increased time of processing.
Utility model content
The deficiency that causes needing before processing repetition effect bland position in order to overcome the inhomogeneous and deformation of products of the surplus size occurring in current blank clamping.The utility model provides a kind of fixture using when processing for injection machine part chaining part, and this fixture can not only allow one of blank axially obtain during self-centering divides fast, and can also deduct the step of correction.
The utility model solves the technical scheme that its technical problem adopts: under the constant prerequisite of original processing technology, redesign fixture to revise blank locate mode, change blank locating surface and changed in two faces of inner side are realized minute by the one side in outside, by with to be processed 5,6 face on a face as in positioning with reference to datum level minute.On fixture, pacified a device, middle unit 19 is divided in location, Ta fixes at center, with manual rotation, drive screw 30 that back-moving spring 26 is resetted, with two can transform size opening chela block the face of two location of blank, two chelas have just formed unsteady benchmark backer, can change according to the variation of blank, and of blank axially also can navigate to a fixing center with chela.
Specifically, the technical solution of the utility model is as follows:
A kind of manufacture full electric injection molding machine self-centering blank fixture, for the processing of injection machine part chaining part, described chaining part has inner side datum level A 1, inner side datum level B 2, Z-direction datum level A 3, Z-direction datum level B 4, to be processed A 5, to be processed B 6, X-direction datum level A 7, X-direction datum level B 8, Y-direction datum level A 9, Y-direction datum level B 10, described manufacture full electric injection molding machine comprises stand A 18 with self-centering blank fixture, stand B 21, clamp bottom board 23, stand A 18 is connected with clamp bottom board 23 by rigging screw 22 with stand B 21, on stand A 18 and stand B 21, is equipped with Y-direction benchmark backer 11, X-direction adjustment screw 12, X-direction pressing plate 13, Y-direction pressing plate 14, Z-direction adjustment screw 15, Y-axis supporting seat A 16, Y-axis supporting seat B 17, Z-direction backer's screw 20, is characterized in that, also has one and locates a minute middle unit 19, and a minute middle unit 19, location has chela A 24, chela axle A 25, back-moving spring 26, chela B 27, chela axle B 28, sliding shoe 29, drive screw 30, unit housings 32 in minute, wherein divide middle unit housings 32 to be accurately arranged on securely on stand B 21, chela A 24 rotates centered by chela axle A 25, chela B 27 rotates centered by chela axle B 28, back-moving spring 26 two ends are connected on chela A 24 and chela B 27, sliding shoe 29 is slidably matched between chela A 24 and chela B 27 and with them, drives screw 30 to be arranged in minute middle unit housings 32 and is against sliding shoe 29 belows.As shown in Figure 6 and Figure 7, chaining part clamping on fixture time, rotarilys actuate screw 30, and it promotes sliding shoe 29, and sliding shoe 29 pushes two chelas 24,27 and opens and clamps chaining part sidewall 31.After machining, retract and drive screw 30, sliding shoe 29 is retracted, and back-moving spring 26 can make two chelas 24,27 retract automatically, thereby the chaining part after processing can be hung oneself from fixture.Owing to having adopted this structure, as long as adjusted minute middle unit 19, location, machined surface 5,6 will remain at applicable position in process.If the one in machined surface 5,6 has deviation, can form malleation to corresponding chela so, thereby the power that makes to be applied on corresponding machined surface increases, and part is carried out to automatic calibration.
For making to proofread and correct minute best effect of middle acquisition, preferably the parts in housing are symmetrical, and therefore preferably chela A 24 and chela B 27 have same size.And sliding shoe 29 can have up-small and down-big tapering, thereby more easily realize opening of chela.
The beneficial effects of the utility model are:
