Description

Technical Field

[0002] CNC grinding equipment is an advanced processing tool. It can not only perform high-precision grinding and polishing work, but also realize automated processing of workpieces through CNC programming, thereby improving processing flexibility and efficiency and reducing the labor intensity of workers. However, after a period of use, the polishing and grinding disc of the grinding equipment will gradually wear out due to its surface, resulting in a decrease in its sharpness and durability. After long-term use, the cutting effect of the cutter head will deteriorate and may even damage the processed material. In order to ensure the processing quality of the equipment, the cutter head of the grinding equipment needs to be replaced after a certain period of use.

[0003] However, when replacing the cutter head of the CNC grinding equipment, technical personnel in this field found that the existing CNC grinding equipment has certain drawbacks. Since most of the current grinding equipment uses bolts to fix the grinding disc, and in the process of using bolts to fix the grinding disc, it is necessary to check whether the bolts match the aperture of the screw hole that fixes the disc. Therefore, it is difficult for the automated process to complete the automatic replacement of the grinding disc, which reduces the production efficiency of the production line. Moreover, in the process of workers replacing the disc, improper operation of the workers may cause the disc to be not firmly fixed or the disc may scratch the worker, and other accidents may occur. Therefore, in order to increase the speed of disc replacement, improve the production efficiency of the production line and reduce the risk of worker injury, technical personnel in this field have proposed a CNC grinding equipment that is easy to replace the cutter head to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a CNC grinding device which is easy to replace the cutter head. The disassembly step of the cutter disc of the CNC grinding device which is easy to replace the cutter head can be automatically completed by the control cabinet, and no longer relies on manual replacement of the blade, thus realizing full automation of blade disassembly, reducing labor costs, and avoiding accidents that may be caused by manual disassembly of the blade, making it safer to use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A CNC grinding device for convenient replacement of a tool head comprises a control cabinet and a three-axis CNC machine tool, wherein the three-axis CNC machine tool is installed at the middle position of the upper side wall of the control cabinet, a grinding angle adjustment motor is installed on the vertical moving axis of the three-axis CNC machine tool, a grinding tool transmission assembly is installed on the movable end of the grinding angle adjustment motor, and the grinding tool transmission assembly comprises a grinding motor, a tool holder and a tool rod;

[0007] The grinding motor is installed on the upper side wall of the tool holder at the front middle position, the tool rod is installed at the bottom of the grinding motor drive shaft, a fixed flow channel is opened on the left side wall of the tool rod at the bottom position, one end of the fixed flow channel close to the central axis of the tool rod is connected with a clamping block through a spring, and a second solenoid valve is installed on the other end of the fixed flow channel, an ejection flow channel is opened at the center of the tool rod, and a T-shaped ejection block is connected to the lower end of the ejection flow channel through a spring, a first solenoid valve is installed on the left side wall of the tool rod and at the same height as the top of the ejection flow channel, the first solenoid valve is connected to the ejection flow channel, and a grinding cutter disc is clamped at the bottom of the tool rod;

[0008] A tool changing assembly is installed on the left side of the rear side wall of the three-axis CNC machine tool, and the tool changing assembly includes a tool changing box, a water tank, a suction dual-purpose pump, a first suction water pipe, a second suction water pipe, a return water pipe and a tool changing slot, wherein the tool changing slot is arranged in the middle of the bottom of the tool changing box, the water tank is installed on the top of the left side wall of the tool changing box, the suction dual-purpose pump is installed on the left side of the lower end surface of the upper side wall of the tool changing box, the second suction water pipe is connected to the top water inlet and outlet of the suction dual-purpose pump, the first suction water pipe is connected to the bottom water inlet and outlet of the suction dual-purpose pump, the top of the return water pipe passes through the bottom of the water tank, and the bottom of the return water pipe is connected to the second suction water pipe;

[0009] Through the above technical solution, the CNC grinding equipment drives the grinding disc to move on the machine tool through the three-axis CNC machine tool, and then grinds and polishes the workpiece. When the control cabinet detects that the grinding disc has reached the scrap service life, it controls the grinding angle adjustment motor to rotate, so that the grinding disc swings upward, and then the horizontal longitudinal moving axis of the three-axis CNC machine tool drives the grinding disc into the tool changing slot in the tool changing box, and then performs the tool changing process. When changing the tool, the first solenoid valve and the second solenoid valve are both opened, and the dual-purpose suction pump is connected through the reflux water pipe and the second suction pump.

[0017] Through the above technical solution, a certain amount of new cutter discs can be placed in the cutter storage groove, and there is no need to frequently add cutter discs manually, which reduces the labor intensity of workers. A certain amount of scrapped cutter discs can be recycled using the recycling barrel, and then the workers can recycle them in a unified manner, which is more convenient.

[0019] Through the above technical scheme, when the old cutter disc is disassembled, the cutter changing motor rotates, and the recovery rod is used to push the old cutter disc into the recovery cylinder, and then the new cutter disc falls into the top of the cutter rod through the circular notch on the isolation disc, and then the suction pump reverses the suction to extract the water stored in the ejection channel. At this time, the T-shaped top block descends, and at the same time, the suction pump injects part of the water in the ejection channel into the fixed channel, and then pushes the block into the slot of the new grinding cutter disc, thereby completing the replacement of the cutter disc, making the replacement of the cutter disc faster and more convenient, and using water to fix the grinding cutter disc, so that its fixing effect is better, and the cutter disc will not loosen due to the fixing gap.

When the control cabinet 1 detects that the grinding disc 600 has reached the scrap service life, it controls the grinding angle adjustment motor 4 to rotate, thereby swinging the grinding disc 600 upward, and then the horizontal longitudinal moving axis of the three-axis CNC machine tool 2 drives the grinding disc 600 into the tool changing slot 305 in the tool changing box 301.

At this time, the T-shaped ejector block 509 descends, and the suction pump 309 injects part of the water in the ejection channel 504 into the fixed channel 508, and then pushes the block 507 into the slot 602 of the new grinding disc 600, thereby completing the replacement of the disc, making the replacement of the disc faster and more convenient. The grinding disc 600 is fixed by water, so that the fixing effect is better and the disc will not become loose due to the fixing gap.
