[0001] The utility model relates to the technical field of compressor controllers, and particularly relates to a fixing tooling for IGBT of a controller. Background Technique
[0002] During the manufacturing process of an electric scroll compressor controller, one of the most important processes is to install IGBT (Insulated Gate Bipolar Transistor). Generally, there are 6 IGBTs on one controller, and their relative positions are required to be strict. If the relative position gap is large and the IGBT pins are uneven, when installing the circuit board later, the pins cannot be smoothly inserted into the circuit board jacks, and a lot of time is required to shape the pins.
[0003] In the prior art, the tooling for IGBT has poor positioning accuracy, which in turn leads to poor processability of fixing IGBT, and there are often rework problems. To avoid such situations, the utility model designs a fixing tooling for IGBT of a controller to solve the above problems. Summary of the Utility Model
[0004] To solve the problems in the background technique, the utility model proposes a fixing tooling for IGBT of a controller, which can ensure the accuracy of IGBT tooling positioning and the convenience of picking and placing.
[0005] To solve the above problems, the utility model adopts the following technical scheme: A fixing tooling for IGBT of a controller, including an upper positioning plate, a lower positioning plate, positioning pins and support pins. The lower positioning plate is arranged below the upper positioning plate. Support pin holes are provided on both the upper positioning plate and the lower positioning plate. The support pin holes are in interference fit with the support pins. The two ends of the support pins are correspondingly connected to the support pin holes on the upper positioning plate and the support pin holes on the lower positioning plate respectively. A positioning pin hole is also provided on the upper positioning plate. The positioning pin hole is in interference fit with the positioning pin. One end of the positioning pin is connected to the positioning pin hole on the upper positioning plate, and the other end of the positioning pin is used to be connected in a threaded through hole on the controller housing. An IGBT special-shaped groove is provided on the top surface of the lower positioning plate, and a through opening is provided on the top surface of the upper positioning plate corresponding to the IGBT special-shaped groove.
[0006] Further, the number of the positioning pin holes and the positioning pins is four each. The four positioning pin holes are respectively arranged at intervals at the corners of the top surface of the upper positioning plate. One ends of the four positioning pins are correspondingly connected in the four positioning pin holes in an interference fit manner, and the other ends of the four positioning pins are correspondingly connected in threaded through holes on the controller housing.
[0007] Furthermore, the number of the support pins is at least two, the number of the support pin holes formed on the upper positioning plate and the lower positioning plate is at least two, at least two of the support pin holes on the upper positioning plate are respectively disposed on two sides of the through hole on the top surface of the upper positioning plate in a one-to-one correspondence, and two ends of at least two of the support pins are in interference connection with at least two of the support pin holes on the upper positioning plate and the lower positioning plate in a one-to-one correspondence.
[0008] Furthermore, the number of the IGBT special-shaped grooves is six, and the six IGBT special-shaped grooves are used for installing IGBTs.
[0009] The beneficial effects of the present utility model: The upper positioning plate of the present utility model is connected to the threaded through hole of the controller housing through a positioning pin. The cooperation of the positioning pin and the positioning pin hole can reduce the positioning error.

The present utility model can ensure the positioning accuracy of the IGBT tooling and the convenience of taking and placing.
[0019] Specifically, as Figures 1 to 5 shown, a controller IGBT fixing tooling includes an upper positioning plate 1, a lower positioning plate 2, a positioning pin 3 and a support pin 4. The lower positioning plate 2 is arranged below the upper positioning plate 1. Support pin holes 5 are formed on both the upper positioning plate 1 and the lower positioning plate 2. The support pin holes 5 are in interference fit with the support pin 4. The two ends of the support pin 4 are respectively connected to the support pin holes 5 on the upper positioning plate 1 and the support pin holes 5 on the lower positioning plate 2 in a one-to-one correspondence. A positioning pin hole 6 is also formed on the upper positioning plate 1. The positioning pin hole 6 is in interference fit with the positioning pin 3. One end of the positioning pin 3 is connected to the positioning pin hole 6 on the upper positioning plate 1, and the other end of the positioning pin 3 is used to be connected in the threaded through hole on the controller housing 7. An IGBT special-shaped groove 8 is formed on the top surface of the lower positioning plate 2, and a through hole 9 is formed on the top surface of the upper positioning plate 1 corresponding to the IGBT special-shaped groove 8.
[0020] Furthermore, the number of the positioning pin holes 6 and the positioning pins 3 is four each.

One ends of the four positioning pins 3 are connected to the four positioning pin holes 6 in interference fit in a one-to-one correspondence, and the other ends of the four positioning pins 3 are connected to the threaded through holes on the controller housing 7 in a one-to-one correspondence.

[0022] Furthermore, the number of the IGBT special-shaped grooves 8 is six, and the six IGBT special-shaped grooves 8 are used for installing IGBTs.
[0023] When the utility model is in use, the upper positioning plate 1 is connected to the threaded through hole of the controller housing 7 through the positioning pin 3. The cooperation between the positioning pin 3 and the positioning pin hole 6 can reduce the positioning error. At the same time, since the number of the positioning pins 3 and the positioning pin holes 6 is four, and the four positioning pin holes 6 are respectively arranged at intervals at the corners of the top surface of the upper positioning plate 1, so as to reduce the positioning error. The IGBT special-shaped grooves 8 processed on the lower positioning plate 2 can ensure the positioning accuracy and the convenience of taking and placing of the IGBTs stored on the lower positioning plate 2. The upper positioning plate 1 and the lower positioning plate 2 are connected by the support pins 4 to form a whole, which can ensure the installation stability between the upper positioning plate 1 and the lower positioning plate 2.
