Description

Technical Field

[0001] The utility model relates to the technical field of roll grinders, in particular to a roll driving device of a roll grinder. Background Art

[0002] The roll grinder is a metal cutting machine tool, which consists of a bed, a headstock, a tailstock, a bracket, a longitudinal and transverse slide, a grinding head, a measuring frame and an electrical numerical control system. It is divided into five subsystems: a bearing system, a drive system, a grinding system, a measuring system and a control system. The workpiece is supported by the headstock, the tailstock and the bracket, and is driven to rotate by the headstock. The numerical control system controls the machine tool to perform multi-axis compound motion according to the mathematical model of the generatrix of the roll surface, and realizes the grinding of the roll surface metal by the grinding wheel during the motion process. The online measurement system feeds back the measurement data to the grinder control system in real time, and the control system performs closed-loop control of the machine tool to complete the precision machining of the workpiece. When the roll grinder is working, it is necessary to use the drive structure to realize the rotation of the roll after clamping, so as to conveniently grind the roll.

[0003] The current roll grinder mainly realizes the rotation of the drive shaft in the grinder spindle box through a single drive motor and a gearbox installed at the power input end of the spindle box, thereby realizing the rotation of the clamped roll during the grinding process. Although the convenient rotation of the clamped roll on the roll grinder can be realized under the action of the above-mentioned drive device, on the one hand, the roll drive device of the above-mentioned structure is only suitable for the convenient rotation requirements of rolls of a specific weight after clamping, and when grinding heavier rolls, the roll drive device of the above-mentioned structure is no longer applicable, resulting in poor flexibility in the use of the roll drive device. On the other hand, since there is only one drive device on the roll grinder, it is easy for the drive motor on the drive device to malfunction during the operation of the roll grinder, resulting in the roll grinder needing to be shut down for a long time for maintenance, which is not convenient for efficient grinding of the rolls.

[0010] Furthermore, the number of belt grooves on the driven pulley is twice the number of belt grooves on the driving pulley.

[0011] By adopting the above technical solution, such a design can ensure that the transmission belts on the upper support plate and the lower support plate can be put into use at the same time.

[0012] Furthermore, the transmission belt is a V-belt, the transmission belt is connected to the driving pulley in a nested manner, and the driving pulley is key-connected to the power output end of the gearbox.

[0013] By adopting the above technical solution, the transmission belt can realize stable transmission of the power of the variable speed motor and the gearbox to the driven pulley.

[0014] Furthermore, the drive motor is bolted to the gearbox, and the power output shaft of the drive motor is keyed to the power input end of the gearbox.

[0015] By adopting the above technical solution, the cooperation between the driving motor and the gearbox is mainly used to realize the convenient rotation of the driving pulley.

[0016] Furthermore, the gearbox is bolted to the slide seat, and the slide seat is bolted to the sliding block on the electric slide rail.

[0017] By adopting the above technical solution, the electric slide rail can realize the synchronous sliding adjustment of the driving pulley with the gearbox. Such a design can facilitate the convenient tightening and installation of the transmission belt.

[0018] Furthermore, the upper support plate and the lower support plate have the same size, and the gearbox, the drive motor, the driving pulley and the driven pulley together constitute a driving mechanism for realizing the rotation of the driven pulley.

[0019] By adopting the above technical solution, it is ensured that two sets of driving mechanisms can be installed on the grinder spindle box at the same time without occupying the space of the grinder spindle box.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the current roll grinder mainly uses a single drive motor and a gearbox installed at the power input end of the spindle box to realize the rotation of the drive shaft in the grinder spindle box, and then realizes the rotation of the clamped roll during the grinding process. Although the above-mentioned drive device can realize the convenient rotation of the clamped roll on the roll grinder, on the one hand, the roll drive device of the above-mentioned structure is only suitable for the convenient rotation demand of rolls of a specific weight after clamping, and when grinding heavier rolls, the roll drive device of the above-mentioned structure is no longer applicable, resulting in poor flexibility in the use of the roll drive device. On the other hand, since there is only one drive device on the roll grinder, it is easy to cause a malfunction of the drive motor on the drive device during the operation of the roll grinder. The problem that the roll grinder needs to be shut down for a long time for maintenance, which is not convenient for efficient grinding of the rolls. The utility model installs a driving mechanism consisting of a driving motor, a gearbox, an active pulley, and a transmission belt on the upper support plate and the lower support plate respectively, and uses an electric slide rail to realize flexible connection and use of the two driving mechanisms and the driven pulley, so that the driving device can not only effectively improve the driving force of the device when in use by putting the two driving mechanisms into use at the same time to meet the device's stable driving requirements for heavier rolls, but also can quickly put the other driving mechanism into use by means of an electric sliding installation when one driving mechanism is damaged, thereby reducing the downtime of the device when the driving mechanism fails and ensuring efficient grinding of the roll on the roll grinder.
