Abstract

The utility model relates to a quick positioning tooling which comprises a fixed plate and positioning keys; the fixed plate is of a circular structure; a plurality of connecting parts are integrally manufactured on the circumferential side of the outer edge of the fixed plate uniformly; the upper end surfaces of the connecting parts are higher than the upper end surface of the fixed plate; each connecting part is provided with a keyway which is radially formed along the fixed plate; one positioning key is arranged in each keyway correspondingly, the upper end surface of each positioning key is higher than the upper end surface of the fixed plate, two long counter bores are symmetrically formed on both sides of each keyway; a threaded hole is formed in the center of the fixed plate. According to the tooling, the connecting parts of three bulges are adopted to fix an upper mould, so that the concentricity of the upper mould with a processing central platform and the precision of a datum plane are effectively ensured; and in addition, when the lower end surface of the upper mould is processed, the upper end surface and the lower end surface of the upper mould can have the same processing datum plane only by processing three positioning keyways which are matched with the positioning key of the tooling. The quick positioning tooling has an ingenious structure, a scientific design and high operability, and effectively improves the working efficiency and the upper mould processing quality.

Description

A kind of quick positioning tool

Technical field

The utility model belongs to technical field of tooling clamps, relates to the location of wheel cast Mould Machining, especially a kind of quick positioning tool.

Background technology

In the machined of wheel cast upper mould is manufactured, usually need to patrix be fixed on the machining center platform by frock, then carry out machined.The tradition fixedly frock of patrix is generally chuck and pressing plate.

For the upper and lower end face machining benchmark that guarantees patrix consistent, need to first process a transverse plane, and then process other end plane after beating the table centering, use above-mentioned frock often when the processing other end, to beat the table centering and require a great deal of time, it is very large that machining accuracy is affected by operating personnel's level of skill.

Therefore be badly in need of promoting the working (machining) efficiency of wheel patrix and the crudy of patrix by improving frock.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of quick positioning tool is provided, and this frock effectively improves the positioning precision of patrix, makes the upper and lower end face benchmark consistent, improves in addition the working (machining) efficiency of patrix.

Technical solutions of the utility model are achieved in that

A kind of quick positioning tool, comprise fixed head and positioning key, this fixed head is circular configuration, the even one of outer circumference side at fixed head is made a plurality of connecting portions, and the upper surface of this connecting portion is higher than the upper surface of fixed head, and each connecting portion is radially made a keyway along fixed head, in corresponding each keyway, place a positioning key, the upper surface of this positioning key is higher than the fixed head upper surface, and each keyway bilateral symmetry is shaped with the countersunk head slotted hole of two, and the center of this fixed head is shaped with a screwed hole.

And described connecting portion is three.

And the upper surface of described positioning key exceeds fixed head upper surface 5mm.

Advantage of the present utility model and good effect are:

This frock adopts the connecting portion of three projections that patrix is fixed, and has guaranteed that effectively patrix is concentric with the machining center platform, makes patrix upper and lower end face machining benchmark consistent; In addition, in processing patrix another side, only need process the locating slot of three groove depth 5mm that coordinate with the tool locating key, two end faces up and down that can realize patrix have identical machining benchmark plane, the upper die structure change is little, its life-span, quality and maintenance etc. can be do not affected yet, the mould fast aligning can be realized.The utility model meter structure is ingenious, and design science is workable, effectively increases work efficiency and the crudy of patrix.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is that the B-B of Fig. 1 is to cutaway view;

Fig. 4 is the utility model working state structure schematic diagram.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of quick positioning tool, comprise fixed head 1 and positioning key 11, this fixed head is circular configuration, as shown in Figure 1 to Figure 3, the even one of outer circumference side of this fixed head is made the connecting portion 5 of three protrusions, the upper surface of these three connecting portions is higher than the upper surface of fixed head, each connecting portion is radially made a keyway 3 along fixed head, in corresponding each keyway, place a positioning key, the upper surface of this positioning key is higher than fixed head upper surface 5mm, each keyway bilateral symmetry is shaped with two countersunk head slotted holes 2, and the center of this fixed head is shaped with a screwed hole 4.

Using method of the present utility model is:

As shown in Figure 4, at first by fixed head screwed hole and 10 centralized positionings of machining center platform, guaranteed that fixed head is concentric with the machining center platform, the screw (not shown) is passed to fixed head countersunk head slotted hole and be fixedly mounted with the machining center platform, then three positioning keys are placed on respectively in the fixed head keyway, be installed together corresponding with positioning key of three locating slot (not shown)s that patrix 6 lower surfaces are evenly made, and by back-up block 9, pressing plate 8 and bolt 7, patrix firmly is fixed on the machining center platform, then carry out machine operations; After the upper surface of patrix machines, in the upper surface of patrix, make equally three locating slots, after oppositely being installed, patrix carries out the lower surface machined.

The utility model has the advantages of for:

This frock adopts the connecting portion of three projections that patrix is fixed, and has effectively guaranteed concentric with the machining center platform and the identical datum level of patrix; In addition, in addition, in processing patrix another side, only need process the locating slot of three groove depth 5mm that coordinate with the tool locating key, two end faces up and down that can realize patrix have identical machining benchmark plane, the upper die structure change is little, its life-span, quality and maintenance etc. can be do not affected yet, the mould fast aligning can be realized.The utility model meter structure is ingenious, and design science is workable, effectively increases work efficiency and the crudy of patrix.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
