Description

Controls for Surface Grinding Machines

technical field

The invention relates to a surface grinder, in particular to a control device for a surface grinder.

Background technique

Referring to Fig. 1, it shows the perspective view of the existing surface grinder, the surface grinder 10 is mainly composed of a base 11, a saddle 12 which is horizontally arranged on the table of the base 11 and moves along a Z axis (front and back), and is vertically arranged on the base 11. A column 13 on the base 11 table, a workbench 14 that moves along the X axis (left and right) and is used to place a workpiece (not shown in the figure), and a workbench 14 that moves along the Y axis (up and down) and that a grinding wheel 15 is installed. Spindle head seat 16. The grinding wheel 15 can be displaced relative to the workbench 14 along the Y-axis direction with the column 13, and at the same time, the saddle 12 can be displaced forward and backward relative to the column 13, and the workbench 14 can be displaced left and right relative to the column 13, so that A surface of the workpiece on the workbench 14 is ground.

In addition, in the operation of the existing surface grinder, the forward and backward movement (Z axis) of the saddle 12 is driven by a motor (including a servo motor), the left and right movement (X axis) of the worktable 14 is driven by a hydraulic cylinder, and the up and down movement of the grinding wheel 15 The movement (Y-axis) is driven by mechanisms such as worm gear and electromagnetic pull rod. With the composition of the above structure, the existing surface grinder has three operating modes: manual grinding, continuous automatic surface grinding and automatic groove grinding. , and its operation mode is mainly switched and selected on the working module selection button 171 on the operation panel 17 .

However, if you want to perform grinding with the continuous automatic surface grinding operation mode, besides selecting the continuous automatic surface grinding position, you must also perform the setting operation described later, for example: for the saddle 12 and the base 11 The front and rear stroke setting mechanism 18 in between carries out the width setting of front and rear stroke; Carry out the setting of each front and rear feed amount (value) to front and rear feed mechanism; After the mechanism completes the plane grinding each time, the downward feeding amount of the grinding wheel 15 is set. In addition, when the thickness is controlled, the amount to be ground also needs to be set for the downward feeding mechanism, and the thickness dimension After the grinding is completed, the lifting amount (value) of the emery wheel 15 should also be set so that the emery wheel 15 is far away from the workpiece and the workpiece can be safely removed.

It can be seen from this that when the conventional continuous automatic surface grinding operation mode is used for grinding, the required settings are scattered in various positions of the surface grinder 10, which is extremely inconvenient to set, and the situation of missing settings will also occur. In particular, the larger the size of the surface grinder, the more inconvenient the setting, and the higher the probability of missing the setting.

In addition, the working module selection button 171 of the existing surface grinder has only three modes for selection, and its effect is only limited to this mode, and the special workpiece grinding mode cannot be used, such as the automatic feed groove grinding on the right side.
