Description

Technical Field

[0001] The utility model relates to the technical field of additive manufacturing, and more specifically to a temperature detection and adjustment device for a turntable of additive equipment. Background Art

[0002] In the five-axis additive manufacturing process, a printing base is installed on the turntable. Additive manufacturing technology uses directed energy deposition technology to produce workpieces from scratch on the printing base. However, a large amount of heat is generated during the production process, causing the workpiece to transfer heat to the printing base, and the printing base transfers heat to the turntable. The turntable is a key functional component that affects the accuracy of the additive equipment. Effective temperature control must be taken on the turntable to ensure printing quality.

[0003] The existing turntable cooling device is directly installed at the bottom of the printing base, but it has the following defects and cannot meet the needs of five-axis additive manufacturing:

[0004] 1. In five-axis additive manufacturing, the turntable needs to be tilted and rotated frequently, especially the rotation is allowed to exceed 360°. In this case, the cooling water channels of the cooling device will be entangled, which may damage the cooling device.

[0005] 2. During the additive manufacturing process, the temperature of the printing base needs to be adjusted in real time according to the process. However, the existing turntable cooling device does not have a temperature detection function, so it is impossible to adjust the temperature of the printing base in real time. There is a risk that heat will be transferred to the machine tool turntable and affect the turntable rotation accuracy. Utility Model Content

[0008] In the above scheme, the temperature detection and adjustment device of the utility model can use a thermocouple to detect the temperature of the printing base of the turntable in real time. Based on the difference between the temperature of the printing base and the ideal temperature, the power of the external water cooler can be controlled in real time by an external host computer to control the water cooling amount of the external water cooler input into the water cooling component through the water-electric integrated slip ring, thereby realizing the temperature adjustment of the turntable printing base.

[0009] The water-electricity integrated slip ring used in the utility model is a commonly used product on the market. It is a slip ring used for conducting electricity and passing water. It is specially used to transmit signals and pass water during unlimited continuous rotation. During the working process, the temperature detection and adjustment device of the utility model can simultaneously realize the temperature detection and adjustment of the printing base plate, and the water-electricity integrated slip ring is used, which does not hinder the rotation and tilt of the turntable, thereby ensuring the accuracy of the turntable rotation during additive manufacturing.

[0010] The hydropower integrated slip ring comprises a slip ring stator and a slip ring rotor; the slip ring stator is connected to the base of the turntable; and the slip ring rotor is connected to the rotating shaft of the turntable.

[0011] The slip-ring stator and the slip-ring rotor are both provided with a water inlet interface, a water outlet interface and a signal line; the water inlet interface of the slip-ring stator is connected with the water outlet interface of the slip-ring rotor, and the water outlet interface of the slip-ring stator is connected with the water inlet interface of the slip-ring rotor; the signal line of the slip-ring stator is connected with the signal line of the slip-ring rotor.

[0012] The water outlet pipeline of the external water cooler is connected to the water inlet interface of the slip ring stator, and the water return pipeline of the external water cooler is connected to the water outlet interface of the slip ring stator.

[0016] The cooling water channel is distributed in a spiral shape inside the water cooling plate and is provided with a water inlet and a water outlet.

[0017] The water inlet interface of the slip ring rotor is connected to the water outlet of the cooling water circuit, and the water outlet interface of the slip ring rotor is connected to the water inlet of the cooling water circuit.

[0018] In order to better detect the temperature, the thermocouple is arranged on the inner wall of the end of the water cooling plate that is attached to the printing base plate.

The external host computer adjusts the power of the external water cooler according to the difference between the actual temperature of the current printing base and the temperature of the printing base required by the additive process. If the temperature of the printing base is too high, the power of the external water cooler is increased, and vice versa, the power of the external water cooler is reduced to control the water cooling amount of the external water cooler input into the water cooling component through the water-electric integrated slip ring, thereby realizing the temperature adjustment of the turntable printing base. The cooling water of the external water cooler enters the water cooling plate through the water-electric integrated slip ring to cool the printing base, and the high-temperature water discharged from the water cooling plate enters the external water cooler through the water-electric integrated slip ring, thereby completing the circulation of the cooling water.

In addition, the water-electric integrated slip is respectively connected to the thermocouple 2 and the external host computer signal to form a detection circuit.

[0027] The water-electricity integrated slip ring 3 used in this embodiment is a commonly used product on the market. It is a slip ring used for conducting electricity and passing water, and is specially used for transmitting signals and passing water during unlimited continuous rotation. During operation, the temperature detection and adjustment device of the utility model can simultaneously detect and adjust the temperature of the printing base plate 1.1, and the water-electricity integrated slip ring 3 is used, which does not hinder the rotation and tilt of the turntable 1, thereby ensuring the rotation accuracy of the turntable 1 during additive manufacturing.

[0028] Specifically, the water cooling assembly includes a water cooling plate 4 and a cooling water path 5. The water cooling plate 4 is installed between the printing base plate 1.1 and the turntable 1.2 of the turntable 1 and is attached to the printing base plate 1.1. The cooling water path 5 is spirally distributed inside the water cooling plate 4 and is provided with a water inlet and a water outlet.

[0029] The hydroelectric integrated slip ring 3 comprises a slip ring stator and a slip ring rotor, wherein the slip ring stator is connected to the base 1.4 of the turntable 1, and the slip ring rotor is connected to the rotating shaft of the turntable 1. The slip ring stator and the slip ring rotor of this embodiment are both provided with a water inlet interface, a water outlet interface and a signal line, wherein the water inlet interface of the slip ring stator is communicated with the water outlet interface of the slip ring rotor, the water outlet interface of the slip ring stator is communicated with the water inlet interface of the slip ring rotor, and the signal line of the slip ring stator is signal-connected with the signal line of the slip ring rotor.

[0030] The water outlet pipe of the external water cooler is connected to the water inlet interface of the slip ring stator, and the water return pipe of the external water cooler is connected to the water outlet interface of the slip ring stator.
