Chip removal system for CNC machine tools

Abstract

The invention relates to the technical field of numerically controlled machine tools, and discloses a chip removal system for numerically controlled machine tools, comprising a material transfer box, a frame is fixedly installed on the top of the material transfer box near the left side, and the bottom end of the frame is fixedly installed. A return spring is fixedly installed at an equidistant distance, and the bottom end of the return spring is fixedly installed with a material guide plate that is located at the right side of the frame. The chip removal system of the CNC machine tool is installed with a frame at the left end of the transfer box, and a motor is fixedly installed at the top of the frame. When the chip removal operation is required, the top of the guide plate can be placed on the CNC machine tool for chip removal. Below the opening, by turning on the motor, the motor can drive the rotation of the drive shaft and then drive the drive belt to rotate. At this time, it can drive the rotation of the main shaft and the material guide rod. The material guide rod collides with the material guide plate so that the material guide plate is inclined relative to the frame , the waste on the guide plate is dumped into the transfer box to complete the feeding of the waste, and the advantage of tilting the guide plate without manual assistance is realized.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a chip removal system of numerical control machine tools. Background technique [0002] CNC machine tool is the abbreviation of Computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] CNC machine tools often produce waste chips during the processing of parts, and if these waste chips are not processed in time, it will cause a...

Problems solved by technology

[0003] CNC machine tools often produce waste chips during the processing of parts, and if these waste chips are not processed in time, it will cause a decrease in the machining accuracy of the parts. In the prior art, a chip removal system is generally installed in the CNC machine tool to carry out The discharge of waste chips is mainly composed of a material transfer box carrying waste chips, a screw feed rod and a filter plate at the bottom. Its main purpose is to separate waste chips from cutting fluid, but in actual use The box is generally placed at the chip outlet of the CNC machine tool, and when the waste chips are stuck here, it is still necessary to manually tilt the material guide plate to cause the waste chips to re-enter the material transfer box and complete the discharge, which is very convenient to use. the inconvenience

[0004] At the same time, the chip removal system of the existing CNC machine tools is generally set at the bottom of the chip removal port, which leads to the waste chips inside the CNC machine tool directly entering the material transfer box through the waste chip port at one time, while the material transfer The volume of the box is generally fixed, that is, its chip removal speed and efficiency are fixed. A large amount of chip removal at one time will cause the overload of the chip removal box and cause the waste chips to be unable to be discharged, which will have a greater impact on the processing process.

[0005] On the other hand, the existing chip removal system of CNC machine tools will be installed with a filter screen to filter waste chips and cutting fluid, and then reuse the cutting fluid. In the process of processing different parts, each part depends on the processing method Different diameters will produce waste chips of different diameters, and the pore size of a single filter screen is fixed, which leads to incomplete separation of cutting fluid and waste chips when the diameter of waste chips is smaller than the diameter of the filter hole, resulting in The cutting fluid cannot be reused, and the use cost is high
