Problems solved by technology

For a workbench with plane degrees of freedom in two directions, the two directions of the workbench are controlled by a separate drive system. Commonly, two sets of servo motor systems are required to drive the workbench to move in this direction, which increases the complexity of the machine tool control system. Development and design costs and chances of system failure

Embodiment 1

[0025] Embodiment 1, when it is necessary to separately drive the movement of the worktable body 1 (X axis), the upper and lower grinding discs in the upper action mechanism 23 will be in contact, and the upper and lower grinding discs in the lower action mechanism 25 will be separated. When the servo motor is running, only the upper action mechanism 23 and the uploading The actuating mechanism 22 acts to move the workbench body 1. When moving in the reverse direction, it is only necessary to control the reverse rotation of the biaxial servo motor 24.

Embodiment 2

[0026] Embodiment 2, when it is necessary to move the workbench body 1 in another direction (Y axis), the upper and lower grinding discs in the upper action mechanism 23 are separated, and the upper and lower grinding discs in the lower action mechanism 25 are in contact. When the servo motor is running, only the lower action mechanism is driven. 25 and the lower transmission mechanism 26 actions, so that the upper drive base 2 moves along the direction of the second rack 31. Similarly, when moving in the opposite direction, it is necessary to control the biaxial servo motor 24 to reverse.

Embodiment 3

[0027] Embodiment 3, when the workbench is far away from the machining spindle, the workbench body 1 and the upper driving seat 2 can be simultaneously driven to move the workpiece quickly to a position close to the spindle, and then adjusted, which can save time for workpiece positioning, To improve efficiency, the specific operation is to contact the grinding discs of the upper and lower action mechanisms.

Abstract

The invention discloses a workbench driven by a single motor, of a machine tool. The workbench driven by the single motor, of the machine tool comprises a workbench body, an upper drive seat and a lower drive seat, wherein a transmission mechanism, an action mechanism and a double-shaft servo motor are arranged in the upper drive seat; the double-shaft servo motor is vertically and fixedly installed; the action mechanism comprises an upper grinding disc, a lower grinding disc, a shaft sleeve, a rotary shaft and a rotary seat; the lower grinding disc is fixedly connected with a transmission shaft of the double-shaft servo motor; the upper grinding disc is relatively arranged above the lower grinding disc; the upper grinding disc is welded and fixed to the shaft sleeve; a bearing is arrangedin the rotary seat; one end of the shaft sleeve is rotationally connected with the rotary seat; the rotary shaft penetrates through the shaft sleeve and the rotary seat, and is fixed to the upper grinding disc; and the transmission mechanism is connected to the other end of the rotary shaft. According to the workbench driven by the single motor, of the machine tool, action control in two directions of the workbench of the machine tool can be realized through the single motor by virtue of the respective cooperation between the grinding disc structures which make mutual contact and the double-shaft servo motor; and a control principle is simpler and more reliable, and beneficial to reducing the design cost.

Description

technical field [0001] The invention relates to the related technical field of machine tool processing equipment, in particular to a single-motor-driven workbench of a machine tool. Background technique [0002] The machine tool table is an important part of the machine tool. The machine tool table is used to accept and fix the workpiece, so that the machine tool can process the workpiece. Commonly used workbenches include rib plate type and box type. The surface of the workbench is usually specially treated to facilitate the processing of various types of workpieces. Machine tool tables are used in various types of machining equipment. Such as CNC milling machines, CNC drilling machines, CNC grinding machines, etc. [0003] In order to meet the needs of parts processing, the machine table usually has a degree of freedom along the X axis or along the X and Y axes, and is driven and moved by the drive system. For a workbench with plane degrees of freedom in two directions,...
