Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled lathes, and more specifically, particularly relates to a numerically controlled lathe using a tool setting instrument. Background Art

[0002] When using a CNC lathe to process parts, it is necessary to measure the tool position through a tool setter, and the tool will be measured every time a cut is made. As the tool wears out, the tool compensation input system is automatically calculated to ensure that the processed size is not affected by tool wear. The tool setter is mostly installed in the lathe when in use. After each measurement, it will be moved to the side of the lathe and moved back to the measurement position for the next measurement.

[0003] For example, CN218874477U discloses a composite double-axis CNC lathe, comprising a frame, the upper end of the frame is slidably connected to a mounting frame, a second electric push rod is fixedly installed on the inner side of the frame, the output end of the second electric push rod is fixedly installed to the right end of the mounting frame, a first electric push rod is fixedly installed on the upper end of the mounting frame, and a mounting plate is slidably connected to the square mouth of the mounting frame; the utility model adopts the above structure, and uses the second motor on the shaft seat to drive the first screw to rotate, so that two moving blocks with opposite threads on the outer side of the first screw can slide in the same direction or in different directions at the lower end of the mounting plate at the same time, and the outer side of the moving block is installed with the first motor, and the output end of the first motor clamps the tool through the connecting chuck, so that the spacing between the double axes can be easily adjusted during the operation of the machine, avoiding the adjustment time occupied by shutdown, thereby greatly improving the efficiency of the lathe.

Most of these debris are adhered to cutting fluid and easily adhere to the measuring surface of the tool setting instrument, making it difficult for the tool to directly contact the measuring surface, affecting the measurement effect of the tool position and the accuracy of the measurement results.
