Abstract

The invention provides an automatic circular welding machine for a plate roller plug. The circular welding machine comprises a lathe bed, a head stock and a tail seat, wherein a machine head is provided with a first speed-reducing motor; and a tail stock is provided with a second speed-reducing motor. The circular welding machine further comprises two four-wheel positioning centre frames, two finals, a third speed-reducing motor and two welding machines, wherein the two four-wheel positioning centre frames are arranged in the middle of the lathe bed at intervals; the two finals are rotationally arranged on the head stock and the tail seat respectively and oppositely; the third speed-reducing motor is installed on the head stock and connected with the finals arranged on the head stock in a transmission mode; and the two welding machines are respectively arranged above the head stock and the tail seat. In the invention, the excircle of a pipe and the centre hole of the plug are taken as positioning references, the excircle of the pipe is centered by the four-wheel positioning centre frames, the centre hole of the plug is centered by the finals, and the centers of the four-wheel positioning frames and the two finals are in the same horizontal line. Thus, the concentricity of the centre hole of the plug and the excircle of the pipe is ensured, thereby ensuring the welding quality.

Description

Roller plug automatic circular welding machine
Technical field
The present invention relates to a kind of welder, relate in particular to a kind of roller plug automatic circular welding machine.
Background technology
In the manufacturing process of printing plate cylinder, two plugs are welded on respectively the two ends of pipe, plug is provided with the centre bore for installation shaft.In order to guarantee the concentricity of plug and pipe, present method normally after good the inside and outside circle car of plug again with the pipe assembling and then carry out boxing and connect.The problem that this welding method exists is:
1, because the diameter of every roller is different, the fit clearance of plug and pipe is wayward, so the concentricity in plug centre bore and the outer garden of pipe differs larger.Finally have influence on the precision of roller.
2, because pipe exists ellipse, bending, wall unevenness equal error, have influence on the concentricity of plug centre bore and pipe cylindrical, turner is adding the cylindrical guarantee roller car that usually will manually adjust roller man-hour.
3, the error of plug centre bore and pipe cylindrical can make the roller wall unevenness after the processing, and roller lays particular stress on larger, has influence on the steel roller printing effect uneven.
Summary of the invention
Purpose of the present invention can make the better roller plug of crudy automatic circular welding machine in order to provide a kind of exactly.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of roller plug automatic circular welding machine, comprise lathe bed, be installed in the headstock and the tailstock that is installed in tailstock of the head of a bed, be provided with for the first reducing motor that drives the headstock move left and right at the head of a bed, be provided with for the second reducing motor that drives the tailstock move left and right at tailstock, be characterized in, also comprise two four-wheel centre of location framves, two top, the 3rd reducing motor and two welding machines, two four-wheel centre of location framves are disposed on the centre of lathe bed for pipe is positioned, two top is installed in rotation on respectively on headstock and the tailstock and arranges in opposite directions, the 3rd reducing motor is installed on the headstock and links to each other and can drive top rotation with top transmission on being installed in headstock, and two welding machines are installed in respectively the top of headstock and tailstock.
The top center of the center of each four wheels in described two four-wheel centre of location framves and two is on the same horizontal line.
Roller plug automatic circular welding machine of the present invention makes it compared with prior art owing to having adopted above technical scheme, have following advantage and and characteristics:
1, girth welding machine of the present invention adopts two welding machines simultaneously two plugs to be carried out boxing, no longer need with the turning of plug inside and outside circle just can be directly plug and tube welding together, reduced equipment, personnel, factory building and the complementary facility of relevant production of plug turning, be conducive to enhance productivity, reduce production costs.
2, plug and tube welding be centre bore take the cylindrical of pipe and plug as positioning datum, welding precision is high, the roller wall thickness after the turning processing is even, the dynamic balance performance of roller is good, can improve the quality of steel roller printing.
3, the rear turner of roller welding adds no longer needs to adjust roller off-centre man-hour, is conducive to improve the productivity ratio of turner.
4, adopt the roller of this welding machine welding can also reduce machining allowance, reduce the consumption of material.
