Description

Vertical shaft round table surface grinding machine
Technical Field
The invention belongs to the technical field of grinding machines, and particularly provides a vertical shaft round table surface grinding machine.
Background
In the vertical shaft round table surface grinding machine, a rotating shaft of a grinding wheel is vertically arranged, the grinding wheel is arranged at the lower end of a grinding machine head, and the grinding machine head is supported by a machine tool body; the grinding machine head drives the grinding wheel to rotate and vertically feeds the workpiece at the lower workbench. The lower end face of the grinding wheel forms a grinding face which is subject to wear after prolonged use and requires dressing.
The inventor knows that other types of grinding machines with grinding wheel online dressing mechanisms exist in the related technical schemes, and the inventor considers that the following technical problems exist when online dressing of the lower end face of the grinding wheel in the vertical shaft round table surface grinding machine is realized:
(1) The lower end surface of the grinding wheel is a grinding working surface, and the vertical feeding of the grinding wheel is easily influenced by the presence of an online finishing wheel;
(2) In order to realize online dressing of the grinding wheel, a part of the grinding working surface needs to be misplaced vertically relative to the workbench, and when the lower end surface of the grinding wheel rotates to a misplaced position relative to the workbench, the grinding working surface is suspended relative to the workbench, the workpiece and the machine tool body; at the moment, the situation that one side of the grinding wheel is lifted up by the counter force of the workpiece and the other side is suspended and not subjected to external force can occur, so that stable rotation of the grinding wheel is not facilitated, and particularly when the rotation speed of the grinding wheel is too high, the contact between the grinding working surface and the workpiece suddenly can influence the rotation stability; the grinding machine is easy to influence the precision and the service life of the grinding machine after long-time use.
(3) In a grinding machine with an adjustable position of a partially online dressing grinding wheel, a linear adjusting mechanism for adjusting the position of the dressing wheel and a structure for driving the grinding wheel to vertically lift are also commonly ball screws. The ball screw is easy to creep during low-speed feeding, so that the relative position adjustment between the dressing wheel and the grinding wheel is invalid.
(4) When the grinding working surface of the grinding wheel is ground by utilizing the dressing wheel at the moment, quick consumption of the dressing wheel is caused; in some technical schemes, the dressing wheel intermittently contacts with or breaks away from the grinding wheel to be dressed, so that the service life of the dressing wheel is prolonged as much as possible under the condition of realizing online dressing of the grinding wheel; however, in view of the above-mentioned technical problem (2), when the dressing wheel is out of contact with the grinding wheel, the grinding wheel is dislocated and the portion far from the table is suspended and unsupported, which affects the rotation stability of the grinding wheel.
