Abstract

The utility model discloses a roll lathe. The roll lathe comprises a lathe bed, a headstock, a chuck, a slide carriage box and a tool rest, wherein the headstock is fixed to the lathe bed in a supported mode through a heightening block, two sets of riding pulleys are arranged on the lathe bed in the longitudinal direction, each set of riding pulleys include two riding pulleys, and each set of riding pulleys are symmetrically arranged on the two sides of the vertical plane where the central line of the chuck is located. The roll lathe can machine rollers with large diameters, large lengths and large weights.

Description

Roll lathe

Technical field

The utility model relates to a kind of lathe, especially for the roll lathe of processing roll.

Background technology

Roll lathe is the lathe that is specifically designed to processing roll.Brand-new roll lathe, due to the price comparison costliness, for general roll production firm, is difficult to bear the cost of buying brand-new roll lathe.And China's five sixties of last century from East European countries' import many roll lathes, shown in Fig. 4 is a kind of of this type of roll lathe, it comprises lathe bed 1, an end at lathe bed 1 is fixed with headstock 2, be provided with chuck 3 on headstock 2, at lathe bed, slip crate 4 be installed, be fixed with knife rest 10 on slip crate 4, the other end of lathe bed be provided with can longitudinal sliding motion on lathe bed tailstock 8, be fixed with top 9 on tailstock.Add man-hour, intend processing roll and fix by chuck 3 and top 9, rotate under the drive of chuck 3, but knife rest 10 passes through the slip crate regulating shaft to the position with radially, and then breaker roll carries out turning processing.

Above-mentioned roll lathe is due to the restriction of range and the top bearing capacity of chuck of its maximum rotating diameter, tailstock, be not suitable for processing that present diameter, length are large, the heavier roll of quality, therefore many places are in idle state, a lot of such roll lathes are arranged on the roll second-hand market, its low price, if can undergo technological transformation, be used, breaker roll production firm, can save a large amount of costs undoubtedly.

Summary of the invention

The purpose of this utility model is to provide a kind of roll lathe, with, quality heavier roll large to diameter, length, is processed.

Roll lathe described in the utility model, comprise lathe bed, headstock, be arranged at chuck, the slip crate on headstock and be positioned at the knife rest on slip crate, between lathe bed and headstock, is provided with keel, and headstock is supported and fixed on lathe bed by keel; Be vertically arranged with two groups of support rollers on lathe bed, every group of support roller has two, and two support rollers are arranged symmetrically in the both sides of described chuck hub line place vertical plane.

When processing roll, roll is positioned on the support roller group, and clamp an end of roll by fixture with chuck, support roller contacts and carries roll with the roll neck place of roll, under the rotarily driving of chuck, be carried on the also and then rotation together of roll on support roller, knife rest passes through the slip crate regulating shaft to the position with radially, and then breaker roll carries out turning processing.

The utility model is owing to by keel, the height of headstock being raise, but thereby increased the diameter range of roll lathe processing roll, by cancelling tailstock, but thereby increased the length range of roll lathe processing roll, and replace the top roll that carries with the support roller group, can carry larger roll weight, thereby make roll lathe described in the utility model can process that diameter, length are large, the heavier roll of quality.

The accompanying drawing explanation

The front view that Fig. 1 is roll lathe described in the utility model;

The right view that Fig. 2 is roll lathe described in the utility model;

Fig. 3 is roll lathe described in the utility model schematic diagram (in figure, dotted line means roll) in use;

The schematic diagram that Fig. 4 is existing roll lathe.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1 to Figure 2, this roll lathe comprises lathe bed 1, headstock 2, is arranged at chuck 3, the slip crate 4 on headstock 2 and is positioned at the knife rest 10 on slip crate, be provided with keel 5 between lathe bed 1 and headstock 2, headstock 2 is supported and fixed on lathe bed 1 by keel 5.Be vertically arranged with two groups of support rollers 6 on lathe bed 1, every group of support roller 6 has two, and two support rollers 6 are arranged symmetrically in the both sides of described chuck 3 center line place vertical planes.

As shown in Figure 3, when processing roll, be positioned on support roller 6 by roll 7 and clamp an end of roll with chuck by fixture, support roller 6 contacts and carries roll 7 with the roll neck place of roll 7, under the rotarily driving of chuck 3, be carried on the also and then rotation together of roll 7 on support roller 6, knife rest 10 passes through slip crate 4 regulating shafts to the position with radially, and then breaker roll 7 carries out turning processing.
