Problems solved by technology

The previous method of straightening and aligning the tooling is generally to use the dial indicator installed on the machine tool spindle to straighten the tooling after placing the tooling on the machine tool. The process is complicated, time-consuming, laborious, and error-prone
Aircraft parts are generally complex in structure, high in material cost, and large in tooling, which determines the high requirement for one-time pass rate of CNC machining to avoid unqualified parts. However, the production preparation work before CNC machining is often complicated and time-consuming, which affects the delivery cycle of parts.

Embodiment Construction

[0018] like figure 1 As shown, a tool setting device for a CNC machine tool, the center of the inverted T-shaped block 1 is a positioning hole 4, and a pin 3 is arranged in the positioning hole 4, and the diameter of the pin 3 is the same as the diameter of the positioning hole 4 Equal, the two ends of the T-shaped block 1 are symmetrically provided with fastening screws 2 .

[0019] A method for fast positioning of tooling of a numerically controlled machine tool, comprising the following steps:

[0020] 1) First drill two through holes on the tooling, record the distance between the two holes and the position coordinates of the two holes relative to the positioning reference hole of the part on the fixture;

[0021] 2) Enter the coordinate value of the width direction center position of a certain T-slot on the machine tool table into the machine tool control system and save it;

[0022] 3) Clamp the pin 3 on the spindle of the CNC machine tool, and put the two T-shaped blo...

Abstract

The invention relates to a tool setting device of a numerical control machine. An inverted T-shaped block is provided with a round positioning hole in the center, a pin is disposed in the round positioning hole, the pin is equal to the round positioning hole in diameter, and fastening screws are symmetrically disposed at two ends of the T-shaped block. The tool setting device is simple in structure, low in production cost, convenient in operation and highly flexible, and is applicable to numerical control machines and conventional machines.

Description

technical field [0001] The invention relates to a tooling fast positioning and tool setting device of a numerical control machine tool, which belongs to auxiliary equipment for mechanical processing. Background technique [0002] CNC machining generally requires tooling, and the positioning of the tooling on the CNC machine tool needs to be straightened and aligned, and the positioning holes or positioning pins on the tooling are used to set the processing origin. The previous method of straightening and aligning the tooling is generally to use the dial indicator installed on the spindle of the machine tool to straighten the tooling after placing the tooling on the machine tool. The process is complicated, time-consuming, laborious, and error-prone. Aircraft parts are generally complex in structure, high in material cost, and large in tooling, which determines the high requirement for one-time pass rate of CNC machining to avoid unqualified parts. However, the production pre...
