It has excellent heat dissipation performance and is suitable for high-power and high-temperature applications and high-density layouts. Its main functions are to provide electrical connections, mechanical support, and electrothermal performance. The production of metal substrates requires multiple processing steps, and fixed tooling is required to keep the metal substrate in a stable position during the process.

[0003] The current method is mostly to use a telescopic mechanism to drive a clamping mechanism to clamp and fix the metal substrate from both sides. This fixing method applies an extrusion force to the metal substrate, which may cause the metal substrate to deform. This fixing method usually requires the metal substrate to be disassembled and assembled again after one side of the metal substrate is processed, which affects processing efficiency and consumes time and manpower.

Guide rods are symmetrically arranged on the top of the pressure plate. The guide rods extend through the top plate of the clamping frame. The inner wall of the clamping frame is paved with anti-slip pads to achieve clamping and fixing of the metal base plate from the upper and lower sides to reduce the influence of deformation.

[0007] Preferably, symmetrical support rods are set up on one side of the fixed vertical plate close to the movable plate, and bidirectional threaded rods are arranged between the support rods to form a transmission and guiding medium.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-4 The utility model provides a fixed tooling for the production of high thermal conductivity metal substrates, including a fixed base plate 1, the fixed base plate 1 is T-shaped as a whole, and the fixed base plate 1 is symmetrically provided with fixing holes 2. Before use, the tooling is fixedly installed on the surface of the processing table to complete the fixation. The top of the fixed base plate 1 is symmetrically provided with fixed vertical plates 3, and the inner side of the fixed vertical plates 3 is provided with symmetrical movable plates 6. The movable plates 6 are all provided with transmission shafts 7 inside the plate bodies. The transmission shaft 7 is fixedly installed with a clamping assembly at one end near the middle of the fixed base plate 1. The clamping assembly includes a clamping frame 10, a telescopic cylinder 11, a guide rod 12, and a pressure plate 13. The transmission shaft 7 is fixedly installed with a clamping assembly at one end near the middle of the fixed base plate 1. The top of the clamping frame 10 is provided with a telescopic cylinder 11, and the telescopic end of the telescopic cylinder 11 is downward. The bottom end of the telescopic cylinder 11 is fixedly connected to a pressure plate 13. The top of the pressure plate 13 is symmetrically provided with a guide rod 12. The guide rod 12 extends through the top plate of the clamping frame 10 to guide and limit the movement of the pressure plate 13, making the lifting of the pressure plate 13 more stable. The inner wall of the clamping frame 10 is paved with a non-slip soft pad, which can provide a certain buffering force when in contact with the metal substrate. A reducer 8 is fixedly installed on the side of the fixed vertical plate 3 away from the middle of the fixed bottom plate 1. The bottom end of the reducer 8 is fixedly connected to the first motor 9. The reducer 8 decelerates the first motor 9 to facilitate the slow rotation of the clamping frame 10.

[0020] When fixing the metal substrate, the telescopic cylinder 11 is extended by the driving controller 15, and the extension of the telescopic cylinder 11 drives the pressure plate 13 to move downward, and the pressure plate 13 moves downward to squeeze and fix the metal substrate. At this time, the surface of the metal substrate is processed by the processing machine. After the surface processing is completed, the first motor 9 is controlled to rotate. The rotation of the first motor 9 is decelerated by the reducer 8 and drives the transmission shaft 7 to the east, thereby driving the clamping frame 10 to rotate, thereby realizing the flipping of the metal substrate.

[0021] See also Figure 1-4A symmetrical support rod 5 is mounted on one side of the fixed vertical plate 3 close to the movable plate 6, and a bidirectional threaded rod 4 is arranged between the support rods 5. The rod bodies of the bidirectional threaded rod 4 and the support rod 5 both pass through the movable plate 6, and the bidirectional threaded rod 4 is screwed together with the movable plate 6. One end of the bidirectional threaded rod 4 is connected to the second motor 14 through the reducer 8. A drive controller 15 is fixedly installed on one side of the second motor 14. The drive controller 15 is collectively installed with control components for controlling the first motor 9, the second motor 14 and the telescopic cylinder 11;

[0022] Before installing the metal substrate, control the second motor 14 to rotate. The rotation of the second motor 14 drives the bidirectional threaded rod 4 to rotate. When the bidirectional threaded rod 4 rotates, it screws with the movable plate 6, so that the two movable plates 6 move closer to or away from each other until the distance between the inner walls of the clamping frame 10 on the movable plate 6 is slightly larger than the distance between the two side surfaces of the metal substrate, and then the metal substrate is placed in the clamping frame 10.

[0023] When using the embodiment of the present application:

[0024] The second motor 14 is controlled to rotate, and the rotation of the second motor 14 drives the bidirectional threaded rod 4 to rotate. When the bidirectional threaded rod 4 rotates, it is screwed with the movable plate 6, so that the two movable plates 6 approach or move away from each other, until the distance between the inner walls of the clamping frame 10 on the movable plate 6 is slightly larger than the distance between the two side surfaces of the metal substrate, and then the metal substrate is placed in the clamping frame 10, and the telescopic cylinder 11 is controlled to extend by the drive controller 15. The extension of the telescopic cylinder 11 drives the pressure plate 13 to move downward, and the pressure plate 13 moves downward to squeeze and fix the metal substrate. At this time, the processing machine is used to process the surface of the metal substrate. After the surface processing is completed, the first motor 9 is controlled to rotate. The first motor 9 rotates and drives the transmission shaft 7 to the east after being decelerated by the reducer 8, thereby driving the clamping frame 10 to rotate, thereby realizing the flipping of the metal substrate.
