Abstract
Description
Technical Field
[0001] This utility model belongs to the field of roll lathe technology, and in particular relates to a cast steel roll lathe that is easy to load and unload. Background Technology
[0002] The roll lathe is a low-speed, heavy-duty cutting machine tool designed for roll processing. It features low speed and high torque, and strong machine tool rigidity. It is mainly used for roughing and finishing flat rolls and rolls with grooves. It has good machining accuracy and working efficiency and is loved by many customers.
[0003] Currently, the rolls are typically hoisted and transported to the lathe using a winch. Then, with the assistance of several people, one end of the roll is inserted into the faceplate on the headstock, and the limit seat is moved to abut against the end of the roll. Removing the roll also requires the assistance of several people, making the operation time-consuming and labor-intensive, and inconvenient for loading and unloading the rolls. Utility Model Content
[0004] To address the above problems, this utility model provides a cast steel roll lathe that is easy to load and unload.
[0005] This utility model is implemented as follows: A cast steel roll lathe that is easy to load and unload includes a bed. A headstock is fixedly installed on one side of the upper end of the bed. A servo motor is horizontally fixedly installed inside the headstock. A turntable is fixedly installed on the drive shaft of the servo motor. A pattern plate is fixedly installed at the end of the turntable opposite to the servo motor. The servo motor drives the pattern plate to rotate through the turntable, thereby driving the roll to rotate. A slide groove is horizontally opened at the middle of the upper end of the bed. A slide plate is installed in the slide groove. A first hydraulic rod mechanism is horizontally fixedly installed on the side of the slide groove opposite to the headstock. One end of the first hydraulic rod mechanism is fixedly connected to the middle of the side wall of the slide plate. Under the action of the first hydraulic rod mechanism, the slide plate moves horizontally along the slide groove. A second hydraulic rod mechanism is vertically and symmetrically fixedly installed at the middle of the upper end of the slide plate. A roller support mechanism is horizontally fixedly installed at the upper end of the second hydraulic rod mechanism. A roll is installed at the upper end of the roller support mechanism. The roller support mechanism smoothly moves the roll. Supported by the ground, the roller mechanism drives the roll to move vertically upwards and downwards under the action of the second hydraulic rod mechanism. A limit seat is vertically installed on the bed away from the headstock. A third hydraulic rod mechanism is horizontally fixed on the bed on the side of the limit seat. One end of the third hydraulic rod mechanism is fixedly connected to the middle of the side wall of the limit seat. The movement direction of the limit seat is towards or away from the headstock. Under the action of the third hydraulic rod mechanism, the limit seat moves horizontally on the bed. A slot is vertically opened at the middle of the upper end of the limit seat near the headstock to support and block the end of the roll. The center of the flower disc, the center of the roller mechanism, and the center of the slot are in the same vertical plane to ensure that the roll rotates smoothly under the action of the servo motor. The width of the slot is the same as the diameter of the roll to prevent the roll from deflecting during rotation. The bottom of the center hole of the flower disc and the bottom of the slot are on the same horizontal plane to ensure that the roll is in a horizontal state.
[0006] Preferably, the roller mechanism includes a box body and rotating rollers. The upper end of the box body is open, and two rotating rollers are horizontally and symmetrically arranged on the upper part of the box body. The two rotating rollers reliably support the rolling mill. The shafts at both ends of the rotating rollers pass tightly through the center of the bearings on the side wall of the box body to ensure that the rotating rollers rotate smoothly.
[0007] Preferably, limit grooves are symmetrically opened horizontally on the upper part of the bed on both sides of the slide groove, and limit blocks are symmetrically fixed at the lower end of the limit seat. The limit blocks are positioned corresponding to the limit grooves and have the same width. The limit blocks are set in the limit grooves, and the limit seats move along the limit grooves to prevent the position of the limit seats from deflecting during the movement.
[0008] Preferably, the bottom of the slot is arc-shaped, which matches the shape of the roller to reduce friction.
[0009] Preferably, the height of the first hydraulic rod mechanism is not greater than the depth of the slide groove, so as to avoid affecting the movement of the limit seat.
[0010] Preferably, the width of the groove is the same as the width of the slide plate to prevent the slide plate from deflecting during movement.
[0011] The beneficial effects of this utility model are: the roller support mechanism reliably supports the roll; under the action of the second hydraulic rod mechanism, the roller support mechanism drives the roll to move up and down in the vertical direction to adjust the height of the roll; a slot is vertically opened at the middle position of the upper end of the limit seat to support and block the end of the roll; under the action of the first hydraulic rod mechanism and the third hydraulic rod mechanism, the two ends of the roll extend into the flower plate and the slot or disengage from them; no need for multiple people to assist, convenient operation, time and labor saving, and convenient loading and unloading of the roll.
