Abstract

The utility model discloses a roll lathe which comprises a lathe body and a lathe head box. A disc chuck is arranged on the lathe head box, a chuck is arranged on the disc chuck, the chuck is formed by connecting a chuck body, two clamping plates and a clamping column in an integrated mode, and two sets of supporting wheels with the number of four are arranged on the lathe body. When the roll lathe is used for machining large rolls, the rolling process is not limited by the lengths of the rolls, and meanwhile in the machining process, the axis of each roll can coincide with that of the chuck.

Description

A kind of roll lathe

Technical field

The utility model relates to a kind of lathe for the machining large roll.

Background technology

Roll lathe is the equipment that is specifically designed to the machining large roll, is applied to the fields such as roll manufacture, roll reparation, and it comprises lathe bed, headstock and tailstock.Roll lathe is added man-hour at breaker roll, is by the floral disc on headstock, the homalocephalus of the driving end of roll to be clamped, and with the tailstock center back-up roll other end, make roll by clamping vacantly on lathe.This kind of roll lathe is owing to having tailstock, therefore the roll of processing thereon can be subject to the restriction of roll length.

Summary of the invention

The purpose of this utility model is to provide a kind of roll lathe, and the roll that makes to process thereon is not subject to the restriction of roll length, and in process, roll axis can keep overlapping with the floral disc axis simultaneously.

Roll lathe described in the utility model, comprise lathe bed and the headstock that is positioned at lathe bed one end, be provided with floral disc on headstock, chuck is installed on floral disc, this chuck is comprised of the disk body combined as a whole, two clamps and clamp column, and clamp is vertical with disk body with the both ends of the surface that clamp column lays respectively at disk body, and two clamps are parallel to each other, and, with clamp column axial line symmetry, chuck clamps and is arranged on floral disc by clamp column; Be provided with two groups of totally four support rollers on lathe bed, two groups of support rollers longitudinally are arranged on lathe bed, every group of support roller along lateral arrangement on lathe bed, and with the perpendicular symmetry at floral disc axial line place.

Further, the supporting roller base that can vertically move along lathe bed is installed on lathe bed, described support roller is fixed on supporting roller base.

The support roller breaker roll plays a supportive role, and roll is carried on support roller can produce relative rotary motion with support roller.

This roll lathe, when work, is intended processing roll and is supported on the support roller of lathe bed, and the homalocephalus of roll driving end is positioned between two clamps on chuck, and two clamps all leave certain interval with the interplanar of homalocephalus.Described chuck is by the floral disc driven rotary, two clamps on disk body by torsional interaction on the homalocephalus of roll, thereby drive roller rotational.Between clamp and homalocephalus, stay gapped purpose to be, clamp is only to the homalocephalus output torque, and do not limit the free degree of the radial direction of homalocephalus, like this, roll can carry out automatic capturing in rotary course, make roll axis and chuck axis keep overlapping, thereby guarantee that roll is all the time with himself axis rotation.

Roll lathe described in the utility model is due to the tailstock of having cancelled existing roll lathe, and use the support roller back-up roll, but make this roll lathe machining large roll, and be not subject to the restriction of roll length, and the use of chuck not only can drive roller rotational, and can carry out automatic capturing in the roller rotational process, make roll axis and floral disc axis keep overlapping, guarantee that roll is all the time with himself axis rotation, and processing that can breaker roll has a negative impact.

Fig. 3 is along the cutaway view of A-A line in Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Roll lathe as shown in Figure 1 and Figure 2, comprise lathe bed 1 and the headstock 10 that is positioned at lathe bed one end, be provided with floral disc 2 on headstock 10, on floral disc 2, chuck is installed, this chuck is comprised of the disk body 4 combined as a whole, two clamps 5 and clamp column 6, and clamp 5 is vertical with disk body with the both ends of the surface that clamp column 6 lays respectively at disk body 4, and two clamps 5 are parallel to each other, and, with clamp column 6 axial line symmetries, chuck is arranged on floral disc 2 by clamp column 6 clampings; Two supporting roller bases that can vertically move along lathe bed 7 longitudinally are installed on lathe bed, on each supporting roller base 7, along lathe bed, are horizontally installed with one group of totally two support roller 3, described two support rollers 3 are with the perpendicular symmetry at floral disc axial line place.

As shown in figures 1 and 3, intend processing roll 8 and be supported on two groups of support rollers 3, between two clamps 5 of its driving end homalocephalus 9 on described disk body, and two clamps 5 leave gap with the interplanar of driving end homalocephalus 9.
