Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0011] Such as figure 1 , figure 2 , image 3 As shown, a processing and positioning device for tapping the inner hole of the threaded cover plate of a spin-on filter includes a positioning pin 1, a screw 2, a positioning slider 3 and a positioning seat 4. The positioning seat 4 is composed of three sections of cylinders, which can be fixed on the machine tool table. The radial direction of the upper cylinder of the positioning seat 4 is provided with an inverted T-shaped slot 4a, and two T-shaped positioning slots are arranged in the T-shaped slot 4a. The slider 3 and the positioning slider 3 are respectively provided with a positioning pin 1. The positioning pin 1 is used for positioning with the existing symmetrical hole on the cover plate workpiece. The two positioning sliders 3 are respectively provided with through vertical screw holes. Use screws 2 to pass ...

Abstract

The invention belongs to the field of machining, and in particular relates to a machining and positioning device for an inner bore. The machining and positioning device comprises a positioning base (4) which is fixed on a workbench of a machine tool, wherein an inverted T-shaped groove (4a) is formed on the upper part of the positioning base (4); two T-shaped positioning slide blocks (3) are arranged in the T-shaped groove (4a); positioning pins (1) are arranged on the positioning slide blocks (3) and are positioned together with the existing symmetrical bores in a workpiece in a matched mode; screw holes which are run through are formed in the positioning slide blocks (3); a screw (2) passes through the positioning slide blocks (3), so that the screw (2) is pressed against a bottom plane of the T-shaped groove (4a) to be fixed; and a through hole (4b) is formed at the central position of the positioning base (4), so that chip removal and cutter back-off are convenient to perform. The positioning device is adjustable; and aiming at different center distances of the symmetrical bores in different products, only the positioning slide blocks are required to be adjusted slightly, so the production efficiency is improved, the management cost is reduced, and the machining and positioning device can be widely applied to the machining of other product parts with similar structures.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a positioning device for processing inner holes of parts with symmetrical holes. Background technique [0002] At present, for the threaded cover plate of the spin-on filter, the center hole tapping of the product with symmetrical holes (inlet and outlet holes), the positioning method adopted is composed of a positioning device and a pressing device. The positioning pin of the positioning device matches the symmetrical hole on the product for positioning. The positioning pin is fixed or adjusted by a screw rod. It is very troublesome to adjust when replacing the product, and the manufacturing cost is high, which is not conducive to normal maintenance; the pneumatic components of the pressing device 1. The pressing claws need to be maintained frequently, and the maintenance cost is high; in the production of multi-variety and small batches, the corresponding positioning and pr...
