Abstract

The utility model relates to a fixture for boring holes of a small box. The fixture comprises a base, and four posts, wherein the bottom surface of the base is processed into a reference plane; the four posts are positioned at four corners of the base and connected with the base; and at least one pair of transverse and horizontal bolt mandrils are respectively connected with the four posts through threads. The post can be selected in shape of angle steel section, and the transverse and the longitudinal bolt mandrils are respectively connected with two edge plates vertical to the posts through threads. While the fixture bores holes on the small box, the box to be processed is disposed in the fixture, the bolt mandrils on the posts are screwed and tightly press against each side of the box so as to clamp and fix the box, and the box to be processed as well as the fixture is arranged on a rotary workbench of a boring machine and is subjected to boring with respect to the bottom surface of the fixture as an accuracy reference plane, thereby achieving the requirement for dimension tolerance, coaxiality and verticality of each shaft hole. The fixture can conveniently bore holes on the small box, and has the advantages of high efficiency and low cost while meeting the processing requirement.

Description

Small box body bore hole anchor clamps

Technical field

The utility model relates to the machining appurtenance, specifically is a kind of small box body bore hole anchor clamps.

Background technology

During the small box body part processing,, in process, need a smart datum level for guaranteeing dimensional tolerance, axiality, the perpendicularity requirement of each axis hole on the drawing.Present general technology mode: take on tank floor, to put some block plates of burn-oning, before the machining box part, earlier steel plate milling is become same plane, with this as the smart datum level in the casing process, after casing machines, remove these steel plates again.There are the waste steel in this technology mode, have increased welding (welding steel plate), milling (milling plain plate), pincers worker (removing steel plate) man-hour, has prolonged shortcomings such as manufacturing procedure, and casing of every processing has all additionally increased above-mentioned cost.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of small box body part bore hole fixture for processing is provided, and uses these anchor clamps and carries out small box body bore hole processing, when satisfying processing request, has efficient height, advantage that cost is low.

The utility model is achieved in that and comprises a base, four root posts, the bottom surface of described base is through being processed into datum plane, described four root posts are positioned at four jiaos of bases and are connected with base, and at least one pair of horizontal and vertical bolt push rod has been threaded respectively on four root posts.

Described column is the angle steel profile shapes, and described horizontal and vertical bolt push rod is threaded in respectively on mutually perpendicular two side plates of column, and each column has two pairs of bolt push rods up and down.

The small box body bore hole is added man-hour, casing to be processed is placed on is positioned on the base in the anchor clamps, promptly between four columns, screw bolt push rod on the column, make the push rod head hold out against each face of casing, casing is fixedly clamped, then casing to be processed is installed on the boring machine rotary table together with anchor clamps, as smart datum level, casing is carried out bore hole processing with the bottom surface of clamp base, can realize dimensional tolerance, axiality, the perpendicularity requirement of each axis hole.

The beneficial effects of the utility model are: conveniently realized the bore hole processing of small box body, avoid waste steel that the common process mode exists, additionally increased man-hour, prolong shortcomings such as manufacturing procedure, when satisfying processing request, have efficient height, advantage that cost is low.

Fig. 3 is that the casing clamping is at anchor clamps inner structure schematic diagram.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises base, four root posts 4, base is two rectangular tube longerons 2 and two square skeleton frames that 1 welding of rectangular tube crossbeam constitutes, the bottom of base evenly distributes and is welded with some block plates 3, steel plate 3 is carried out Milling Process form smart datum level, four columns 4 adopt angle steel, are welded with two pairs of nuts 6 up and down on two side plates of each column 4 angle steel, are connected with two pairs of bolt push rods 5 with nut 6.

As shown in Figure 3, after casing 7 was packed in the anchor clamps, bolt push rod 5 screwed with nut 6 on four columns 4 of anchor clamps, holds out against casing 7 each face respectively, and casing 7 is fixedly clamped.Clamping there are the anchor clamps of casing 7 be installed on the boring table 8 by T type slot bolt 9, pressing plate 10, as smart datum level, casing 7 are carried out bore hole processing with the bottom surface of clamp base as one.After casing 7 machines, casing 7 is separated with these anchor clamps, another casing to be processed of packing in these anchor clamps continues the processing of casing.
