Abstract

The utility model relates to a positioning device for an inner-welded disc part of a straight-hole long barrel. The positioning device comprises a fixture body. Two V-shaped positioning blocks are arranged on the fixture body, a straight-hole long barrel part is placed on the V-shaped positioning surfaces of the V-shaped positioning blocks, and the fixture body is provided with a positioning mandrel for positioning the disc part. With the positioning device, positioning is facilitated and reliable, positioning accuracy is improved, labor intensity is reduced, and working efficiency is improved.

Description

Pad class part positioning device in the long tube of straight hole

Technical field

The utility model relates to a kind of positioner, specifically, relates to pad class part positioning device in the long tube of a kind of straight hole.

Background technology

Generally during no positioning step welding disk-like accessory in the long tube of present straight hole adopt a vertical major axis class positioning core axle, the long barrel part of external diameter location straight hole of axle, the shaft shoulder of axle and spool the microcephaly locate disk-like accessory, locate with three to four spot welding.Its shortcoming is: longer, generally all more than 1 meter, very inconvenient when being inserted in mandrel because of long tube kind part, the some postwelding has distortion again, takes out also very difficult; Production efficiency is low.

The utility model content

At above-mentioned deficiency of the prior art, it is a kind of simple in structure, easy to make that the utility model provides, and the location is reliable, can improve the interior pad class part positioning device of the long tube of straight hole of positioning accuracy.

Technical solution adopted in the utility model is:

Pad class part positioning device in the long tube of a kind of straight hole comprises clamp body, and described clamp body is provided with the V-type locating piece, and the long barrel part of straight hole is placed on the V-type locating surface of V-type locating piece, and clamp body is provided with the positioning core axle that disk-like accessory is positioned.

Described V-type locating piece is two.

The beneficial effect of the relative prior art of the utility model:

Pad class part positioning device in the long tube of the utility model straight hole is located conveniently, reliably can be improved positioning accuracy, reduces labour intensity, increases work efficiency.

Description of drawings

Fig. 1 is pad class part positioning device master TV structure schematic diagram in the long tube of the utility model straight hole;

Fig. 2 is that left TV structure schematic diagram is adorned in pad class part location in the long tube of the utility model straight hole.

Critical piece symbol description in the accompanying drawing:

Among the figure:

1, clamp body 2, positioning core axle

3, V-type locating piece 4, the long barrel part of straight hole, disk-like accessory combination.

The specific embodiment

Followingly with reference to drawings and Examples the utility model is described in detail:

Accompanying drawing 1,2 as can be known, pad class part positioning device in the long tube of a kind of straight hole comprises clamp body 1, and described clamp body is provided with V-type locating piece 3, the long barrel part of straight hole is placed on the V-type locating surface of V-type locating piece 3, and clamp body 1 is provided with the positioning core axle 2 that disk-like accessory is positioned; Described V-type locating piece 3 is two.

Pad class part positioning device in the long tube of the utility model straight hole with the long barrel part of V-block location straight hole of two horizontal positioned, does not need to clamp on the clamp body, in the vertical direction of two V-type locating surfaces, makes a positioning core axle location disk-like accessory.Shorter because of a disk-like accessory interior length of packing into, and long barrel part does not compress, and does not also influence part and takes out even point is welded with distortion; Because of long barrel part horizontal positioned, so the lift height of part reduces greatly, be convenient to upper and lower pieces in addition.

As shown in Figure 1, 2, pad class part positioning tool in the long tube of straight hole in positioning core axle 2 location, utilizes two screwed holes that disk-like accessory is strained disk-like accessory, again the long barrel part of straight hole is located at two V-type locating pieces 3, and make it correctly to locate at the positioning core axle end face.At bevel for welding welding three to four point locations and fixing.

Claims

1. a straight hole is grown pad class part positioning device in the tube, comprise clamp body, it is characterized in that: described clamp body is provided with the V-type locating piece, and the long barrel part of straight hole is placed on the V-type locating surface of V-type locating piece, and clamp body is provided with the positioning core axle that disk-like accessory is positioned.
