The driving unit is a pneumatic driving device.
The mounting plate is provided with a kidney-shaped hole for the guide sleeve to pass through, the cross section of the upper end of the guide sleeve is T-shaped, the guide pillar is further provided with a bearing, the bearing is positioned between the lower surface of the upper end of the guide sleeve and the upper surface of the mounting plate, and the upper end of the guide sleeve and the bearing are fixedly pressed on the mounting plate through a gland and a bolt.
The bearing is a plane bearing, two surfaces of the plane bearing, which are attached to the bearing ring of the mounting plate, are planes, and the balls of the plane bearing roll on the plane of the bearing ring at the lower end.
The lower end of the driving unit is connected with the workbench through a connecting flange.
The lower surface of the workbench is provided with a plurality of T-shaped mounting grooves.
The working principle of the invention is as follows: the workstation is used for installing the mould and carries out work, and the mould can make with the workstation contact, generally with cast iron or steel, because work needs, the mould need refrigerate or heat, can radiate low temperature or high temperature conduction to the workstation on, the workstation consequently expend with heat and contract with cold, the geometric dimensions changes.
The surface of the T-shaped mounting groove of the workbench is provided with a tool to complete the work. If the tool emits low temperature lower than the ambient temperature or high temperature higher than the ambient temperature, the low temperature or the high temperature is conducted and radiated to the workbench, and the geometric dimension of the workbench is reduced or expanded. The mounting plate provided with the guide sleeve is far away from a temperature source, and the worktable blocks temperature radiation, so that the influence of the temperature source is small, and the change of the geometric dimension is small. In the process, the guide precision of the guide sleeve and the guide column changes, if the temperature source emits low temperature, the distance between the guide column connected with the workbench becomes small, and if the temperature source emits high temperature, the distance between the guide column connected with the workbench becomes large.
A special plane bearing is arranged between the guide sleeve and the mounting plate, two sides of a bearing ring of the special plane bearing, which is attached to the mounting plate, are flat, and balls of the special plane bearing can roll on the plane of the bearing ring at the lower end. The mounting plate is provided with a waist-shaped hole for the guide sleeve to pass through, and the guide sleeve and the special plane bearing are pressed and fixed on the mounting plate through a gland by bolts. If the geometric dimension of the workbench changes due to temperature difference, the guide states of the guide pillar and the guide sleeve are dynamic when the workbench, the guide pillar and the guide pillar connecting frame reciprocate along the guide sleeve. At this time, the guide sleeve can automatically adjust the geometric position along the waist-shaped hole on the plate, and the special plane bearing arranged between the guide sleeve and the plate ensures the stability and the guiding precision in the horizontal direction when the geometric position of the guide sleeve is automatically adjusted.
The invention has the advantages that: the mounting plate provided with the guide sleeve is far away from a temperature source, and the worktable blocks temperature radiation, so that the mounting plate is slightly influenced by the temperature source, and the change of the geometric dimension is small; a special plane bearing is arranged between the guide sleeve and the mounting plate, so that the stability and the guiding precision in the horizontal direction when the geometric position of the guide sleeve is automatically adjusted are ensured; the waist-shaped hole for the guide sleeve to pass through is processed on the mounting plate, if the workbench changes in geometric dimension due to temperature difference, when the workbench, the guide pillar and the guide pillar connecting frame reciprocate along the guide sleeve, the guide states of the guide pillar and the guide sleeve are dynamic, the precision balance of the guide mechanism cannot be broken, and the problem that the guide mechanism of the equipment is locked and damaged and cannot be used is solved.
