[0002] Scroll compressors are a common type of compressor used in automotive air conditioning systems. They consist of a moving plate, a stationary plate, and a housing. During assembly, the housing and stationary plate need to be assembled together. Current technology uses a fixed tooling base for assembling the housing and stationary plate. When installing the components, a sealing ring needs to be installed on the outer ring of the stationary plate. If the positioning is unstable, the stationary plate is prone to displacement and changes in angle, thereby increasing potential quality risks. Utility Model Content

The top surface of the annular base is used to support the compressor housing. The annular base is provided with a housing positioning pin corresponding to the positioning hole of the compressor housing. The top component includes a top block, a support block, and an arc-shaped block fixedly connected together from bottom to top. The top component is located inside the annular base and its lower end extends into the opening of the sliding plate. The support block is located above the annular base, and the bottom surface of the support block is used to contact the top surface of the annular base. The outer edge of the support block is located inside the housing positioning pin. The arc-shaped block is fixed to the upper surface of the support block to support the stationary plate. The arc-shaped block is provided with a stationary plate positioning pin corresponding to the positioning hole of the stationary plate.

[0005] The top surface of the annular base is provided with a positioning groove extending into the inner circumference of the annular base. The side of the positioning groove closest to the inner circumference of the annular base is open. A positioning block is provided in the positioning groove to limit the position of the top block. The positioning block is fixed in the positioning groove by a fixing bolt. The outer circumference of the annular base is provided with a positioning bolt for horizontal setting. The positioning bolt is used to press the positioning block inward.

[0006] The top block adopts a T-shaped plate structure that is larger at the top and smaller at the bottom. There are two positioning grooves and two positioning blocks. The positioning blocks slide with the two sides of the upper end of the T-shaped plate.

[0007] The top block is provided with a boss at a position lower than the positioning block. When the top block pushes the stationary plate upward, the boss contacts the bottom surface of the positioning block.

[0008] A guide post is provided between the support block and the annular base. The support block has a guide hole for the guide post to pass through, and the guide post slides up and down with the guide hole.

[0009] The annular base is provided with guide post mounting holes corresponding to the guide holes in the support block. The guide post mounting holes are T-shaped holes with a smaller top and a larger bottom.

The opening on the slide plate 1 adopts a cross groove 1.1, and a handle 1.2 is fixed on the upper surface of the slide plate. The annular base 2 is vertically oriented and is fixedly connected to the upper surface of the slide plate 1 by bolts. The opening of the slide plate 1 is enclosed inside the annular base 2. The top surface of the annular base 2 is used to support the compressor housing 12. The annular base 2 is provided with a housing positioning pin 4 corresponding to the positioning hole of the compressor housing 12. The top member 3 includes a top block 3.1, a support block 3.2, and an arc-shaped block 3.3 fixedly connected together from bottom to top. The top member 3 is located inside the annular base 2 and its lower end extends into the opening of the slide plate 1. The support block 3.1 is located above the annular base 2. The bottom surface of the support block 3.1 is used to contact the top surface of the annular base. The outer edge of the support block 3.1 is located inside the housing positioning pin 4. The arc-shaped block 3.3 is fixed to the upper surface of the support block 3.2 to support the stationary disc 13. The arc-shaped block 3.3 is provided with a stationary disc positioning pin 5 corresponding to the stationary disc positioning hole.

[0034] The annular base 2 has a positioning groove 6 extending into its inner circumference on its top surface. The positioning groove 6 is open on the side closest to the inner circumference of the annular base 2. A positioning block 7 is provided within the positioning groove 6 to limit the movement of the top block 3.1. The positioning block 7 is fixed within the positioning groove 6 by fixing bolts. The annular base 2 has positioning bolts 8 on its outer circumference for horizontal positioning, which are used to press the positioning block 7 inwards. The top block 3.1 adopts a T-shaped plate structure, wider at the top and narrower at the bottom. There are two positioning grooves 6 and two positioning blocks 7, with the positioning blocks 7 slidingly engaging with the two sides at the upper end of the T-shaped plate. A boss is provided on the top block 3.1 below the positioning block 7. When the top block 3.1 presses upwards against the stationary plate, the boss contacts the bottom surface of the positioning block 7.

[0035] A guide post 9 is provided between the support block 3.2 and the annular base 2. The support block 3.2 has a guide hole 10 for the guide post 9 to pass through, and the guide post 9 slides vertically with the guide hole 10. The annular base 2 has a guide post mounting hole 11 corresponding to the guide hole 10 in the support block 3.2. The guide post mounting hole 11 is a T-shaped hole that is smaller at the top and larger at the bottom. The lower end of the guide post 9 has a protruding edge that fits into the lower end of the T-shaped hole, and the protruding edge matches the lower end of the T-shaped hole.

[0036] There are two guide posts 9, which are symmetrically arranged. There are two arc-shaped blocks 3.3, which are arranged opposite to each other, and each arc-shaped block 3.3 has a stationary plate positioning pin 5 on its top surface. There are two housing positioning pins 4, which are symmetrically arranged.

[0037] The usage state of the base fixture used for assembling the compressor housing and stationary plate in this embodiment is as follows: Figures 3 to 4 As shown, the annular base 2 is fixedly installed on the slide plate 1 by four bolts. The two positioning holes of the annular base 2 are each fitted with a housing positioning pin 5. The support block 3.2 of the top part 2 is placed on the annular base 2. The positioning hole on the arc-shaped block 3.3 of the top part 3 is fitted with a stationary plate positioning pin 5. Before assembling the stationary plate and housing, place the stationary plate 13 on the top piece 3. The top surface of the support block 3.2 supports the bottom of the stationary plate 13. The stationary plate 13 is positioned by the stationary plate positioning pin 5. The arc-shaped block 3.3 cooperates with the spiral line of the stationary plate 13 to limit the stationary plate. Place the compressor housing 12 on the annular base 2. The annular base 2 positions the compressor housing 12 by the housing positioning pin 4. After the compressor housing 12 and stationary plate 13 are in place, hold the handle 1.2 and push the slide plate 1 to the machine tool processing position. Use the pressure head above the machine tool to press the compressor housing 12 down. The output end of the power mechanism (usually a cylinder) on the machine tool pushes the top block 3.1 from bottom to top. The entire top piece 3 moves upward to lift the stationary plate 13, pushing the stationary plate 13 to contact the inner side of the top surface of the compressor housing 12. Therefore, the positioning of the stationary plate 13 is very stable and there will be no deviation. Then install the compressor housing 12 and stationary plate 13 to improve the qualification rate of compressor assembly. The positioning holes can be re-drilled at different locations according to different compressor models, thereby changing the positions of the housing positioning pin and the stationary plate positioning pin to meet the assembly and use requirements of different compressor components. Therefore, one tooling can be used for multiple different compressor models, which has the advantage of saving costs.
