Abstract

A positioning fixture for castings, the upper end of the base is provided with four positioning blocks opposite to each other, each positioning block is provided with two outwardly facing jacking wires, and each positioning block is provided with two corresponding Support nail a, the upper end of the base and the inner side of the positioning block are provided with four V-shaped blocks that are opposite to each other, and the upper end of the base and the outer side of the V-shaped block are provided with four support that are opposite to each other nail b. Compared with the prior art, the utility model has the advantages of improving processing efficiency and the like.

Description

Positioning fixture of foundry goods

Technical Field

The utility model relates to an anchor clamps especially relate to an used anchor clamps of foundry goods aftertreatment processing.

Background

Casting blanks of black and colored castings have casting openings, flash, burrs and the like and need post-treatment, the prior adopted process method is grinding treatment, and grinding of the traditional casting blanks is basically completed by manual grinding, so that not only the grinding precision and the cleanness of the grinding part cannot be guaranteed, but also the working efficiency cannot meet the requirements. At present, an intelligent machine tool or an industrial robot is basically adopted for polishing a casting blank, a casting opening and burrs of the blank are mainly polished, when the casting blank is polished by the intelligent machine tool or the industrial robot, a workpiece needs to be clamped and positioned by a clamp, and the existing clamp has the phenomenon of inaccurate positioning in the actual clamping process, so that the blank is easy to deform and the polishing accuracy cannot be guaranteed; in addition, the existing positioning fixture can only clamp one workpiece at a time, and the machining efficiency is influenced.

Disclosure of Invention

An object of the utility model is to provide a positioning fixture of foundry goods for solve the technical problem that current anchor clamps location is inaccurate, only work piece of clamping.

The utility model provides a positioning fixture of foundry goods, it includes a base, and the upper end of base is equipped with four two liang of relative locating pieces, all is equipped with two jackscrews outwards on every locating piece, all is equipped with two support nail an that correspond on every locating piece, the upper end of base and the inboard that is located the locating piece are equipped with four two liang of relative V-arrangement pieces, the upper end of base and the outside that is located the V-arrangement piece are equipped with four two liang of relative support nail b.

Further, as the utility model discloses a preferred scheme still includes four point hold-down mechanism, and this four point hold-down mechanism includes the support frame of an I shape, and the middle part of support frame is equipped with the briquetting, and support nail c is all established to four tip of support frame.

The utility model is suitable for a tight location of clamp to the work piece when foundry goods blank utilizes intelligent lathe or industrial robot to polish, compare with prior art, the utility model discloses can press from both sides tight 4 work pieces once, improve machining efficiency greatly, simultaneously, the utility model provides a location that actually presss from both sides tight in-process existence is inaccurate to deformation condition technical problem easily appears in the blank, guarantees the accuracy of polishing.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings

As shown in fig. 1 and 2, a casting positioning fixture comprises a base 1, wherein four pairwise opposite positioning blocks 2 are arranged at the upper end of the base, two outward jackscrews 3 are arranged on each positioning block, two corresponding supporting nails a4 are arranged on each positioning block, four pairwise opposite V-shaped blocks 5 are arranged at the upper end of the base and on the inner sides of the positioning blocks, and four pairwise opposite supporting nails b6 are arranged at the upper end of the base and on the outer sides of the V-shaped blocks.

As shown in fig. 3 and 4, the four-point pressing mechanism includes an i-shaped supporting frame 701, a pressing block 702 is disposed in the middle of the supporting frame, and supporting pins c703 are disposed at four ends of the supporting frame.

As shown in fig. 5 and 6, during operation, a clamping and positioning area is formed by the adjacent V-block 5 and the positioning block 2, the workpiece 8 is mounted on the V-block 5, the support pins a4 and the support pins b, and after the four-point pressing mechanism 7 is mounted, the support pins c703 thereon are respectively pressed on the corresponding workpieces, so as to realize the clamping and positioning operation of the four workpieces.
