The present invention relates to an adjustment device of a grinding machine which contains a first system and a second system interacted with the first system so that the first system and the second system are moved in seven-axis directions.
Conventional automatic computer program control machines (such as CNC grinding machines) cannot grind workpieces at any desired angles.
For example, a grind device of the grinding machines is too simplified to grind the workpieces in multiple axis directions and cannot be controlled in a computer numerical control manner. Even though the grinding machines are controlled in the CNC control manner, the tools are expensive and cannot be adjustably moved to a desired angle accurately.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide an adjustment device of a grinding machine which contains a first system and a second system interacted with the first system so that the first system and the second system are moved in seven-axis directions.
An adjustment device of a grinding machine contains: a first system and a second system. The first system is a grinding unit, and the second system is a tool fixing unit. The grinding unit and the tool fixing unit are mounted on a base of the grinding machine.
The grinding unit includes a first guide rail and a second guide rail on which the grinding unit is driven to move in a first X-axis direction and a first Y-axis direction of the base.
The tool fixing unit includes a horizontal rotation mechanism mounted on the base parallel to a first XY plane, a locating portion, a third guide rail arranged on a rotation disc of the horizontal rotation mechanism and configured to move the tool fixing unit in a second X-axis direction of the base, a fourth guide rail arranged above the third guide rail and configured to move the tool fixing unit in a second Y-axis direction of the base, and a fifth guide rail arranged above the fourth guide rail and configured to move the tool fixing unit in a Z-axis direction of the base.
The locating portion is cylindrical, parallel to a second XY plane, and has a rotation axis defined on a center of the locating portion, such that the locating portion rotates along the rotation axis and a tool is positioned on the locating portion to rotatably grind the workpiece at different angles.
With reference to
The first system is a grinding unit 1, and the second system is a tool fixing unit 2, wherein the grinding unit 1 and the tool fixing unit 2 are mounted on a base 10 of the grinding machine, the grinding unit 1 includes multiple first grind wheels 11 horizontally arranged thereon, multiple second grind wheels 12 vertically arranged on the grinding unit 1, a first guide rail 13 and a second guide rail 14 on which the grinding unit 1 is driven to move in a first X-axis direction and a first Y-axis direction of the base 10.
The tool fixing unit 2 includes a horizontal rotation mechanism 21 mounted on the base 10 parallel to a first XY plane, a locating portion 23, a third guide rail 25 arranged on a rotation disc 22 of the horizontal rotation mechanism 21 and configured to move the tool fixing unit 2 in a second X-axis direction of the base 10, a fourth guide rail 26 arranged above the third guide rail 25 and configured to move the tool fixing unit 2 in a second Y-axis direction of the base 10, and a fifth guide rail 27 arranged above the fourth guide rail 26 and configured to move the tool fixing unit 2 in a Z-axis direction of the base 10. The locating portion 23 is cylindrical, parallel to a second XY plane, and has a rotation axis 24 defined on a center of the locating portion 23, such that the locating portion 23 rotates along the rotation axis 24 and a tool 3 is positioned on the locating portion 23 to rotatably grind the workpiece at different angles.
Referring to
As shown in
Thereby, the grinding unit 1 and the tool fixing unit 2 are adjustably moved in the seven-axis directions to grind the workpiece along the rotation axis 24 by ways of the first guide rail 13, the second guide rail 14, the third guide rail 25, the fourth guide rail 26, the fifth guide rail 27, the horizontal rotation mechanism 21, and the locating portion 23. The adjustment device is control to move and rotate in a computer numerical control manner and by a motor, and the computer numerical control manner and the motor are a well-known art, further remarks are omitted.
Accordingly, the grinding unit 1 and the tool fixing unit 2 are adjustably moved in the seven-axis directions to grind the workpiece. The grinding unit 1 includes the multiple first grind wheels 11 horizontally arranged thereon and the multiple second grind wheels 12 vertically arranged on the grinding unit 1, and the grinding unit 1 is driven to move in the first X-axis direction and the first Y-axis direction of the base 10. The locating portion 23 of the tool fixing unit 2 moves in the second X-axis direction, the second Y-axis direction, and the Z-axis direction of the base 10, and the locating portion 23 is fixed on the rotation disc 22 of the horizontal rotation mechanism 21 parallel to the second XY plane and rotates along the rotation axis 24 so that the tool is moved in the seven-axis directions, and the locating portion 23 is rotated to the desired angle, thus grinding the workpiece accurately and quickly.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
