Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a vertical spindle tool changer mechanism. Background Technology

[0002] In existing vertical machining centers and other equipment, the tool changing mechanism is a crucial component. However, traditional vertical spindle tool changing mechanisms have some shortcomings in terms of tool head disassembly and tool maintenance. For example, tool head disassembly typically requires multiple tools and several cumbersome steps, consuming significant time and manpower. Moreover, tool maintenance often requires removing tools one by one, making it impossible to operate multiple tools simultaneously, resulting in low maintenance efficiency and consequently impacting the overall machining production efficiency.

Each mounting hole contains a tool. Rotating rods are rotatably mounted on the upper and lower inner walls of the tool magazine. Two side plates are fixedly mounted on the center of each side of the tool disc. A connecting rod is rotatably mounted between the two side plates via a pivot pin. A connecting mechanism is provided between the connecting rod and the corresponding rotating rod. The connecting rod is limitedly connected to the corresponding rotating rod through the connecting mechanism. A transmission mechanism is provided on the inner wall of the top of the tool magazine to drive the corresponding rotating rod to rotate.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a vertical spindle tool changing mechanism.

[0024] Reference Figures 1-3 The vertical spindle tool changer includes a tool magazine 1 and a tool disc 2. The tool disc 2 is located in the middle of the tool magazine 1. The surface of the tool disc 2 has multiple mounting holes, and each mounting hole contains a tool 3. Rotating rods 4 are rotatably mounted on the upper and lower inner walls of the tool magazine 1. Two side plates 11 are fixedly mounted in the middle of both sides of the tool disc 2. A connecting rod 10 is rotatably mounted between the two side plates 11 through a shaft pin 12. A connecting mechanism is provided between the connecting rod 10 and the corresponding rotating rod 4. The connecting rod 10 is limitedly connected to the corresponding rotating rod 4 through the connecting mechanism. A transmission mechanism is provided on the inner wall of the top of the tool magazine 1 to drive the corresponding rotating rod 4 to rotate.

[0025] Reference Figures 1-3 The connecting mechanism includes a threaded rod 14 and a wedge block 13. The threaded rod 14 is fixedly mounted on one end of the rotating rod 4 near the connecting rod 10. A wedge groove is provided on the side wall of the threaded rod 14, and the wedge block 13 is engaged inside the wedge groove. One side of the wedge block 13 is fixedly connected to the corresponding connecting rod 10. An internal threaded ring 15 is threaded onto the outer wall of the threaded rod 14. The inner wall of the internal threaded ring 15 abuts against the two sides of the wedge block 13. Both the front and rear sides of the wedge block 13 are arc-shaped, so that the inner wall of the internal threaded ring 15 can stably abut against the side wall of the wedge block 13. The outer wall of the internal threaded ring 15 is provided with anti-slip texture to increase the friction between the hand and the internal threaded ring 15 and prevent slippage during rotation as much as possible.

[0026] Reference Figures 1-3 The transmission mechanism includes a first bevel gear 5 and a second bevel gear 6. The first bevel gear 5 is fixedly sleeved on the rod wall of the upper rotating rod 4. A vertical plate 8 is fixedly installed on the inner wall of the top of the tool magazine 1. A transmission rod 7 is rotatably installed on the side of the vertical plate 8 near the rotating rod 4. The second bevel gear 6 is fixedly sleeved on the end of the transmission rod 7 near the first bevel gear 5. The first bevel gear 5 and the second bevel gear 6 are meshed and connected. A motor 9 is fixedly installed on the side of the vertical plate 8 away from the transmission rod 7. The output end of the motor 9 is fixedly connected to one end of the transmission rod 7. The motor 9 is fixedly connected to the vertical plate 8 through a support frame, making the connection between the motor 9 and the vertical plate 8 more stable.

[0027] In this invention, during use, the motor 9 first drives the transmission rod 7 to rotate. The transmission rod 7 drives the upper rotating rod 4 to rotate through the meshing of the second bevel gear 6 and the first bevel gear 5. The rotating rod 4 drives the connecting rod 10 to rotate through the connecting mechanism, thereby driving the cutter head 2 to rotate and realize the replacement of the cutter 3. When the cutter head 2 needs to be disassembled for maintenance, the internal threaded ring 15 is rotated to move the internal threaded ring 15 away from the outside of the wedge block 13. Then, the wedge block 13 is pulled forward to disengage it from the wedge groove of the threaded rod 14, releasing the limiting connection between the connecting rod 10 and the rotating rod 4. This allows the cutter head 2 to be quickly removed from the tool magazine 1 for multi-tool maintenance. After maintenance, the cutter head 2 is reinstalled into the tool magazine 1, the wedge block 13 is re-engaged into the wedge groove of the threaded rod 14, and the internal threaded ring 15 is rotated in the opposite direction to block the outside of the wedge block 13, realizing the limiting connection between the connecting rod 10 and the rotating rod 4, thus completing the installation of the cutter head 2.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
