Description

Technical Field

[0001] The utility model relates to the technical field of roll grinders, in particular to a roll adjusting mechanism for 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 roller surface generatrix, and realizes the grinding of the roller 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 on the machine tool, thereby completing the precision machining of the workpiece.

[0003] When processing rolls of different diameters, the current roll grinder first places the roll to be processed on a support seat in a hoisting manner, and then repeatedly lifts and lowers the roll for comparison to ensure that the center holes at both ends of the roll are aligned and fixed with the top shaft on the roll grinder. Although the roll can be tightened and fixed under the above adjustment method, the height adjustment of the roll is achieved through manual visual observation and repeated comparison, which makes the height adjustment efficiency of the roll relatively low, and is not conducive to efficient grinding of the roll. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide a roller adjustment mechanism for a roller grinder which can realize rapid adjustment of the roller height by means of laser positioning and facilitate rapid tightening and grinding of the roller in response to the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes a roller adjustment mechanism for a roller grinder, comprising a base plate, two support shells are symmetrically installed on both sides of the upper end of the base plate, a sleeve rod is installed on one side wall of each support shell, a telescopic rod is installed in the sleeve rod, an electric push rod 2 is installed between the telescopic rod and the sleeve rod, an electric push rod 1 is installed on one side of the upper end of the telescopic rod, the telescopic part of the electric push rod 1 is connected to a mounting plate with an inverted T-shaped structure, and two laser lamps are symmetrically installed in the middle of the two side walls of the mounting plate.

[0008] Furthermore, each of the support shells is an upper open structure, and two electric hydraulic rods are symmetrically installed in each of the support shells. The telescopic parts of the two electric hydraulic rods are connected to a support seat, and a placement groove for supporting the rolling roller is opened in the middle of the upper end of the support seat.

[0009] By adopting the above technical solution, the electric hydraulic rod is mainly used to realize automatic adjustment of the height of the support seat, and the support seat is mainly used to realize convenient placement of the roller to be ground.

[0010] Furthermore, support rollers are installed at equal intervals in the placement groove on each of the support seats, and the connection between the placement groove and the support rollers is a concave structure.

[0011] By adopting the above technical solution, the support roller can reduce the friction between the roller and the support seat when the roller rotates during the grinding process.

[0012] Furthermore, the support shell is welded to the base plate, and the sleeve rod is connected to the support shell by bolts.

[0013] By adopting the above technical solution, it can be ensured that the sleeve rod is stably installed and fixed on the supporting shell.

[0014] Furthermore, the telescopic rod is slidably connected to the sleeve rod, the fixing portion of the second electric push rod is connected to the internal bolts of the sleeve rod, and the telescopic portion of the second electric push rod is connected to the internal bolts of the telescopic rod.

[0015] By adopting the above technical solution, the second electric push rod is mainly used to realize the automatic extension adjustment of the telescopic rod from the sleeve rod. At the same time, the cooperation between the sleeve rod and the telescopic rod can also ensure the vertical load-bearing capacity of the second electric push rod.

[0016] Furthermore, the fixing portion of the electric push rod 1 is connected to the telescopic rod by bolts, and the telescopic portion of the electric push rod 1 is connected to the mounting plate by bolts.

[0017] By adopting the above technical solution, the electric push rod is mainly used to adjust the height of the laser lamp. When the center of the rolling roller and the center of the top shaft on the rolling roller grinder coincide with the corresponding light spot of the laser lamp, it means that the height of the rolling roller is adjusted to the correct position, so that the rolling roller can be quickly clamped and fixed.

[0018] Furthermore, the laser lamp is plugged into the mounting plate, and the two laser lamps on the same mounting plate have the same height and are on the same vertical plane.

[0019] By adopting the above technical solution, the laser lamp is the main component for achieving roller height positioning.

[0020] (III) Beneficial effects

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

[0022] To solve the problem that when the current roll grinder processes rolls of different diameters, the roll to be processed is first placed on a support seat in a hoisting manner, and then the roll is repeatedly lifted and lowered for comparison to ensure that the center holes at both ends of the roll are aligned and fixed with the top shaft on the roll grinder. Although the roll can be tightened and fixed in the above adjustment method, the height adjustment of the roll is achieved through manual visual observation and repeated comparison, which makes the height adjustment efficiency of the roll relatively low, and is not convenient for efficient grinding of the roll. The utility model adopts the design of a sleeve rod, a telescopic rod, an electric push rod one, an electric push rod two, a mounting plate and a laser lamp, so that the adjustment mechanism can achieve rapid adjustment of the roll height by a two-way laser positioning method when in use, ensuring that the roll can be quickly tightened and fixed when fixed on the roll grinder, thereby facilitating efficient grinding of the roll.
