Description

Technical Field

[0001] This utility model relates to the field of sculpture processing technology, specifically a tool changing mechanism for a CNC sculpture processing machine. Background Technology

[0002] CNC sculpting machines are automated processing equipment widely used in industries such as handicrafts and architectural decoration. They can precisely process complex sculpted shapes through program control. During the sculpting process, due to the characteristics of the materials being processed (such as wood and stone), different types of sculpting tools often need to be changed according to the processing stage to meet different process requirements such as roughing and finishing. Therefore, the efficiency and reliability of the tool changing mechanism directly affect the overall performance and production efficiency of the sculpting machine.

[0003] Currently, existing CNC sculpting machines are typically equipped with automatic tool changing systems, which generally include a tool magazine and a tool-changing robot to achieve automatic tool exchange. However, these tool changing mechanisms still have some shortcomings in practical applications. First, during the sculpting process, sawdust, dust, and other residues easily adhere to the tool surface, especially when processing wood materials, where sawdust can adhere in large quantities to the tool. Existing tool changing mechanisms usually do not integrate cleaning functions during tool changing. When the removed tool is directly placed back into the tool magazine, residues are carried into the magazine, which may not only contaminate other tools but also cause tool magazine jamming or accelerated tool wear, affecting tool life and machining accuracy. Second, although some machines have independent cleaning stations, the cleaning process is separated from the tool changing process, requiring additional steps and reducing tool changing efficiency, making it difficult to meet the needs of continuous processing. In addition, traditional tool changing mechanisms often have complex structures and long movement paths during tool exchange, increasing tool changing time, and lack targeted protection measures for the tools, such as dust prevention and timely cleaning.

[0004] Therefore, there is an urgent need for a tool changing mechanism for CNC sculpting machines that can integrate tool cleaning functions, improve tool changing efficiency, and ensure the tool storage environment, in order to solve the above-mentioned problems existing in the prior art. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a tool changing mechanism with cleaning function and high tool changing efficiency.

The air outlet of the exhaust fan is connected to the outer wall of the sculpture processing table.

[0012] The beneficial effects of this utility model are: 1. This utility model integrates a tool cleaning component, which automatically cleans used sculpting tools during tool changing. When the tool unloading component returns the replaced tool to the tool magazine, it passes through a tool cleaning station where rotating brushes and a negative pressure dust extraction system effectively remove wood chips and dust adhering to the tool surface. This process prevents contaminants from being carried into the tool magazine, thus ensuring a clean environment inside the tool magazine, reducing abnormal tool wear, and improving the accuracy of subsequent processing.

[0013] 2. This utility model optimizes the tool changing process, integrating multiple actions such as tool picking, tool changing, cleaning, and tool placement into a smooth automated path. The tool changing component is driven by a rotary motor to a double-jaw drive arm, completing the exchange of old and new tools in a single rotation, resulting in rapid operation. Simultaneously, the cleaning step is completed concurrently with the tool transfer, eliminating the need for additional downtime and significantly improving tool changing efficiency, thus meeting the requirements of continuous automated processing.

[0014] 3. The tool magazine assembly of this utility model is equipped with an openable dust cover, which can completely cover the tools during non-tool changing periods, effectively isolating them from external dust. Combined with the pre-cleaning function of the tool washing assembly, this ensures a safe storage environment for the tools. This dual protection mechanism significantly extends the service life of precision tools, reduces maintenance costs, and minimizes the risk of machining quality issues caused by tool contamination.

[0015] 4. The overall layout of this utility model is reasonable and the structure is compact. Each component, such as the sculpting processing component and the tool placement component, is driven by sliding guide rails and hydraulic cylinders, ensuring precise movement. The tool magazine can move on the translational guide rail to facilitate tool loading and unloading, resulting in high space utilization. This modular design not only ensures the reliability of the mechanism's operation but also makes the overall structure of the equipment less bulky, facilitating its installation and maintenance on CNC sculpting machines.

[0016] 5. This invention achieves fully automated operation from tool changing to cleaning, requiring no manual intervention. Operators only need to preset the processing program, and the equipment can automatically complete all steps, including tool selection, exchange, cleaning, and storage. This greatly reduces the labor intensity and skill requirements of operators, while eliminating errors or delays caused by human factors, and improving the safety and intelligence level of production.

The tool placing assembly 5 is fixedly connected to one end of the lateral guide rails 2 for placing the sculpting tool from the tool changing assembly 4 back into the tool magazine assembly 6, or for sending the sculpting tool from the tool magazine assembly 6 to the tool changing assembly. On one side of component 4, directly below the tool placement assembly 5, is a tool magazine assembly 6 for storing various sculpting tools. On one side of the tool magazine assembly 6 is a tool cleaning assembly 7. During the process of the tool placement assembly 5 being returned to the tool magazine assembly 6 by the tool changing assembly 4, the tool placement assembly 5 cleans the replaced sculpting tools to prevent wood chips from the surface of the sculpting tools from being brought into the tool magazine assembly 6. Both the tool cleaning assembly 7 and the tool magazine assembly 6 are fixedly connected to the sculpting processing table 1. The tool changing assembly 4 is fixedly connected to one edge of the sculpting processing table 1 to realize the exchange of sculpting tools between the spindle 105 and the tool placement assembly 5.

[0021] The sculpting processing component 3 includes a first mounting frame 101, a first sliding guide rail 102, a first hydraulic cylinder 103, a sculpting motor 104, and a spindle 105. The first mounting frame 101 is fixedly connected to the sliding block of the lateral sliding guide rail 2. The first sliding guide rail 102 is fixedly connected to one side of the upper end of the first mounting frame 101. The first hydraulic cylinder 103 is fixedly connected to the sliding block of the first sliding guide rail 102. The sculpting motor 104 is fixedly connected to the end of the push rod of the first hydraulic cylinder 103. The spindle 105 is fixedly connected to the end of the rotating shaft of the sculpting motor 104. In specific operation, the sculpting processing component 3 can move horizontally in the X-axis direction through the lateral sliding guide rail 2, while the first sliding guide rail 102 can move horizontally in the Y-axis direction. The first hydraulic cylinder 103 can drive the motor and the spindle 105 to move vertically in the Z-axis direction, and then the spindle 105 drives the rotating sculpting cutter to perform processing operations.

[0022] In the above technical solution, the tool changing assembly 4 includes a right-angle frame 201, a second hydraulic cylinder 202, a rotary motor 203, and a drive arm 204. The right-angle frame 201 is fixedly connected to the edge of the sculpting table 1. The second hydraulic cylinder 202 is fixedly connected to the right-angle frame 201. The rotary motor 203 is fixedly connected to the end of the push rod of the second hydraulic cylinder 202. The end of the rotating shaft of the rotary motor 203 is fixedly connected to the middle of the drive arm 204. The two ends of the drive arm 204 are symmetrically provided with chucks 205. The tool placing assembly 5 pre-loads the tools waiting in the tool magazine. The replacement sculpting cutter is delivered to one side of the tool changing assembly 4. Then, the sculpting processing assembly 3 drives the sculpting motor 104 and the spindle 105 to move to the other side of the tool changing assembly 4. The rotary motor 203 drives the drive arm 204 to rotate, so that the chucks 205 at both ends of the drive arm 204 clamp and remove the sculpting cutter on the tool placement assembly 5 and the sculpting cutter on the spindle 105, respectively. Then, the rotary motor 203 drives the drive arm 204 to rotate 180°, thereby realizing the exchange of tools between the spindle 105 and the tool placement station.

[0023] In the above technical solution, the tool release assembly 5 includes a second mounting bracket 301, a second sliding guide rail 302, a third hydraulic cylinder 303, and a tool sleeve 304. The second mounting bracket 301 is fixedly connected to one end of the lateral sliding guide rail 2. The second sliding guide rail 302 is fixedly connected to one side of the upper end of the second mounting bracket 301. The third hydraulic cylinder 303 is fixedly connected to the sliding block of the second sliding guide rail 302. The end of the push rod of the third hydraulic cylinder 303 is fixedly connected to the tool sleeve 304. When a tool change is required, the third hydraulic cylinder 303 first slides along the second sliding guide rail 302 to the tool magazine assembly. Directly above 6, the tool sleeve 304 is perpendicular to the sculpting tool to be replaced. Then, the third hydraulic cylinder 303 drives the tool sleeve 304 to descend, so that the sculpting tool is snapped into the tool sleeve 304. After that, the sculpting tool is sent to the side of the tool changing assembly 4 along the second sliding guide 302 for tool changing preparation. After the tool changing is completed, it returns along the second sliding guide 302. During this process, the tool cleaning assembly 7 cleans the replaced sculpting tool to remove any wood chips or dust that may be attached to the surface, in order to keep the surface of the sculpting tool clean. Finally, it is put back into the tool magazine assembly 6.

[0024] In the above technical solution, the tool magazine assembly 6 includes a tool magazine frame 401, a tool holder plate 402, a dust cover 403, and a translation guide rail 404. The tool magazine frame 401 is slidably connected to the translation guide rail 404, and the translation guide rail 404 is fixedly connected to the sculpting worktable 1. The tool holder plate 402 is fixedly connected inside the tool magazine frame 401. Several evenly spaced guide grooves are provided on one side of the tool holder plate 402. The dust cover 403 is hinged to one side of the tool magazine frame 401. In this utility model, the dust cover 403 is closed or opened by a motor. When a tool needs to be changed, the tool sleeve 304 of the tool release assembly 5 is first connected to one of the sculpting tools, and then the tool is moved along the translation guide rail. Driven by 404, the tool magazine 401 moves horizontally, causing the sculpting knife held by the tool sleeve 304 to disengage from the tool groove mechanism 405, thus lifting the sculpting knife upwards for knife placement. During the knife placement operation, the translation guide 404 moves the tool magazine 401 to make room, allowing the removed sculpting knife to move down to one side of the tool magazine 401. Afterwards, the translation guide 404 returns to its original position and moves. At this time, the tool groove mechanism 405 on the tool holder plate 402 engages with the sculpting knife on the tool sleeve 304. Finally, during the upward movement of the third hydraulic cylinder 303, the sculpting knife disengages from the tool sleeve 304. Finally, the dust cover 403 is closed and connected to the tool magazine 401 by the motor.

[0025] In the above technical solution, the knife cleaning assembly 7 includes a knife cleaning block 501, a knife cleaning cylinder 502, a brush 503, a rotary motor 504, an exhaust pipe 505, a filter 506, and an exhaust fan 507. An installation groove is provided on the sculpting processing table 1 on one side of the knife magazine assembly 6. The knife cleaning block 501 is fitted into the installation groove. A knife cleaning groove is provided at the upper end of the knife cleaning block 501. The rotary motor 504 is fixedly connected to the bottom of the knife cleaning groove, and a knife cleaning tool is fixedly connected to the shaft of the rotary motor 504.

A gap is left between the outer wall of the washing cylinder 502 and the inner wall of the washing trough. Several through holes 508 are opened on the outer wall of the washing cylinder 502 inside the washing trough. Several brushes 503 are fixedly connected to the inner wall of the washing cylinder 502. An exhaust pipe 505 is fixedly connected to the outer wall of the washing block 501, and one end of the exhaust pipe 505 is connected to the bottom of the washing trough. The other end of the duct 505 is connected to the filter 506, and the other end of the filter 506 is connected to the exhaust fan 507. Both the filter 506 and the exhaust fan 507 are fixedly installed inside the sculpture processing table 1. The exhaust end of the exhaust fan 507 is connected to the outer wall of the sculpture processing table 1. When the replaced sculpture knife is sent back to the knife magazine assembly 6, it will pass over the knife washing assembly 7. When it reaches the knife washing assembly 7, the third hydraulic cylinder 303 drives the knife sleeve 304 and the sculpture knife to move downward, so that the sculpture knife enters the knife washing cylinder 502 vertically. Then, the rotary motor 504 is started, and the rotary motor 504 drives the knife washing cylinder 502 to rotate. The brush 503 in the knife washing cylinder 502 cleans the wood chips and dust attached to the surface of the sculpture knife. In addition, during this process, the exhaust fan 507 draws the air out of the knife washing tank, so that the brushed wood chips are sucked into the knife washing tank through the through hole 508, and then enter the filter 506 for filtration and interception along the exhaust duct 505 from the knife washing tank.
