After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool, and automatically processes parts according to the shape and size required by the drawing. CNC machine tools often use heat dissipation tooling for heat dissipation.

[0003] According to a publicly disclosed fan heat dissipation tooling (publication number: CN111917242A), it includes a fan, which is installed on a frame, and the fan outlet is connected to the main air duct; an expansion body is provided on the main air duct; an ice storage chamber is provided inside the expansion body, and drainage pipes are fixedly connected to both ends of the ice storage chamber; the drainage pipe extends to the outside of the main air duct and is fixedly connected to the main air duct; water outlets are provided at both ends of the drainage pipe; elastic rubber plugs are provided at the water outlets; an ice adding pipe is provided above the ice storage chamber cavity; a temperature monitoring device is provided on the pipe near the elastic rubber plug; the ice storage chamber is fixedly connected to the expansion body through a support frame; a rotary joint is provided on the main air duct near the lower side of the expansion body, and the L air duct is connected to the main air duct through the rotary joint. The above application documents perform corresponding heat dissipation operations by blowing out cold air, but the device is likely to be blocked by debris when no heat dissipation is required. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a heat dissipation tooling that prevents chip blockage, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a heat dissipation tooling that prevents chip blockage, including a CNC machine tool body, the bottom of the CNC machine tool body is fixedly connected to a heat dissipation tooling body, the inner wall of the heat dissipation tooling body is fixedly connected to a servo motor, the top of the servo motor is connected to a heat dissipation fan through its output shaft, and an anti-blocking component is arranged inside the heat dissipation tooling body;

[0005] The anti-blocking component includes hydraulic chamber 1 and hydraulic chamber 2. The inner wall of the hydraulic chamber 1 is connected to a power plate by an elastic rod. The outer piston of the hydraulic chamber 1 is slidably connected to an arc plate. The piston at one end of the hydraulic chamber 2 is slidably connected to a force rod. The piston at the other end of the hydraulic chamber 2 is slidably connected to a gear rod. A spring is fixedly connected to the side of the force rod. The inner wall of the heat dissipation tooling body is rotatably connected to a gear, and the rear end of the gear is fixedly connected to an anti-blocking plate.

[0006] Preferably, the stress-bearing rod is located at a side position of the arc-shaped plate, and the stress-bearing rod is in contact with the arc-shaped plate, so that when the arc-shaped plate moves, the stress-bearing rod can move accordingly.

[0007] Preferably, the spring is located inside the second hydraulic compartment, and the spring is fixedly connected to the inner wall of the second hydraulic compartment, so that the force-bearing rod can be reset under the action of the spring when no force is applied.

[0012] The utility model provides a heat dissipation tool that prevents debris from clogging. It has the following beneficial effects:

[0013] (1) The heat dissipation fixture that prevents debris from clogging starts the servo motor to drive the heat dissipation fan to rotate. When the CNC machine tool body is cooled, the anti-blocking plate rotates and the heat dissipation fixture body is opened by cooperating with the hydraulic chamber 1, the power plate, the elastic rod, the arc plate, the force rod, the spring, the hydraulic chamber 2, the gear rod and the gear. Similarly, when the servo motor is turned off, the anti-blocking plate is reset and the heat dissipation fixture body is closed, so that the device is less likely to be blocked by debris when heat dissipation is not required.

[0014] (2) When the stress-bearing rod moves to the side, the stress-bearing rod drives the transmission rod fixedly connected to it, so that the transmission rod drives the baffle fixedly connected to it to move, and the baffle moves away from the heat dissipation hole, opening the heat dissipation hole to assist in heat dissipation, thereby improving the heat dissipation effect of the device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] See also Figure 1-3 A heat dissipation tooling for preventing debris from clogging comprises a CNC machine tool body 1, a heat dissipation tooling body 2 is fixedly connected to the bottom of the CNC machine tool body 1, a servo motor 3 is fixedly connected to the inner wall of the heat dissipation tooling body 2, a heat dissipation fan 4 is connected to the top of the servo motor 3 through its output shaft, and an anti-clogging component is arranged inside the heat dissipation tooling body 2;

[0023] The anti-blocking component includes a hydraulic chamber 1 5 and a hydraulic chamber 2 6. The servo motor 3 is started to drive the cooling fan 4 connected to its output shaft to rotate. When the CNC machine tool body 1 is cooled, the hydraulic chamber 1 5 connected to the output shaft of the servo motor 3 rotates rapidly. The inner wall of the hydraulic chamber 1 5 is connected to a power plate 8 by setting an elastic rod 7. The outer piston of the hydraulic chamber 1 5 is slidably connected to an arc plate 9. When the hydraulic chamber 1 5 rotates rapidly, the power plate 8 in the hydraulic chamber 1 5 immediately pulls the elastic fixedly connected thereto under the action of centrifugal force. Rod 7 moves, cooperates with the hydraulic chamber 15 which is slidably connected to the piston of the power plate 8, so that the pressure in the hydraulic chamber 15 increases, driving the arc plate 9 which is slidably connected to the piston of the hydraulic chamber 15 to move, and the piston at one end of the hydraulic chamber 26 is slidably connected to a force rod 10, which is located at the side of the arc plate 9, and the force rod 10 is in contact with the arc plate 9, and the piston at the other end of the hydraulic chamber 26 is slidably connected to a gear rod 11, and a spring 12 is fixedly connected to the side of the force rod 10, and the spring 12 is located inside the hydraulic chamber 26, and the spring 12 is in contact with the arc plate 9. The inner walls of the hydraulic chamber 2 6 are in a fixed connection state. When the arc plate 9 moves, the arc plate 9 squeezes the force rod 10, so that the force rod 10 squeezes the spring 12 fixedly connected to it, and moves, and cooperates with the hydraulic chamber 2 6 that is slidably connected to the piston of the force rod 10, so that the pressure in the hydraulic chamber 2 6 increases, driving the gear rod 11 that is slidably connected to the piston of the hydraulic chamber 2 6 to move, and the inner wall of the heat dissipation tool body 2 is rotatably connected with the gear 13, and the gear 13 is located at the top position of the gear rod 11, and the gear 13 is in a meshing state with the gear rod 11. The rear end of 13 is fixedly connected with an anti-blocking plate 14. When the gear rod 11 moves, the gear rod 11 drives the gear 13 fixedly connected thereto to rotate, and the gear 13 drives the anti-blocking plate 14 fixedly connected thereto to rotate, thereby opening the heat dissipation tooling body 2 for heat dissipation; similarly, when the servo motor 3 is turned off and the heat dissipation stops, the power plate 8 is reset under the action of the elastic rod 7, and the force-bearing rod 10 is reset under the action of the spring 12, so that the anti-blocking plate 14 is reset and the heat dissipation tooling body 2 is closed, so that the device is less likely to be blocked by debris when heat dissipation is not required.

[0024] When in use, the servo motor 3 is started to drive the cooling fan 4 connected to its output shaft to rotate. When the CNC machine tool body 1 is cooled, the hydraulic chamber 5 connected to the output shaft of the servo motor 3 rotates rapidly. The power plate 8 in the hydraulic chamber 5 then pulls the elastic rod 7 fixedly connected to it under the action of centrifugal force, causing it to move, and the hydraulic chamber 5 connected to the piston of the power plate 8 is slidably connected to increase the pressure in the hydraulic chamber 5, driving the arc plate 9 connected to the piston of the hydraulic chamber 5 to move, and the arc plate 9 squeezes the force rod 10, so that the force rod 10 squeezes the elastic rod 7 fixed to it. The connected spring 12 moves, and cooperates with the hydraulic chamber 2 6 which is slidably connected to the piston of the force-bearing rod 10, so that the pressure in the hydraulic chamber 2 6 increases, and drives the gear rod 11 which is slidably connected to the piston of the hydraulic chamber 2 6 to move, so that the gear rod 11 drives the gear 13 fixedly connected to it to rotate, and the gear 13 drives the anti-blocking plate 14 fixedly connected to it to rotate, thereby opening the heat dissipation tooling body 2 for heat dissipation; similarly, when the servo motor 3 is turned off and the heat dissipation stops, the power plate 8 is reset under the action of the elastic rod 7, and the force-bearing rod 10 is reset under the action of the spring 12, so that the anti-blocking plate 14 is reset and the heat dissipation tooling body 2 is closed.

[0026] See also Figure 1-4 , based on the first embodiment, a heat dissipation component is provided inside the heat dissipation tool body 2;

[0027] The heat dissipation assembly includes a transmission rod 15, which is located at the front end of the force-bearing rod 10. The transmission rod 15 and the force-bearing rod 10 are in a fixed state. A baffle 16 is fixedly connected to the side of the transmission rod 15. When the force-bearing rod 10 moves to the side, the force-bearing rod 10 drives the transmission rod 15 fixedly connected thereto, so that the transmission rod 15 drives the baffle 16 fixedly connected thereto to move. A heat dissipation hole 17 is opened on the side of the heat dissipation tooling body 2. When the baffle 16 moves, the baffle 16 is away from the heat dissipation hole 17, and the heat dissipation hole 17 is opened to perform auxiliary heat dissipation, thereby improving the heat dissipation effect of the device.

[0028] During use, based on the first embodiment, when the stress-bearing rod 10 moves sideways, the stress-bearing rod 10 drives the transmission rod 15 fixedly connected thereto, so that the transmission rod 15 drives the baffle 16 fixedly connected thereto to move, and the baffle 16 moves away from the heat dissipation hole 17, opening the heat dissipation hole 17 for auxiliary heat dissipation.
