AI Technical Summary
Existing scroll plate fixing devices suffer from unstable mechanical clamping, which causes the scroll plate to easily warp and deform during processing, affecting processing accuracy.
Using the principle of vacuum adsorption, the scroll plate is firmly adsorbed onto the fixed base through a sealing ring and a vacuum generator. The vacuum force is evenly distributed to fix the scroll plate and prevent deformation.
It improves the clamping reliability and stability of the scroll plate, ensures machining accuracy, reduces deformation, and meets machining tolerance requirements.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing technology and relates to a vacuum adsorption device for machining the scroll plate of an automotive air conditioning scroll compressor. Background Technology
[0002] The scroll plate is a crucial moving component of the automotive air conditioning scroll compressor. During milling, the scroll plate needs to be secured. Existing scroll plate securing devices (such as...) Figure 1 (As shown) It mainly includes a base 1 with a fixed seat 2 and multiple cylinders 3. The cylinders 3 are equipped with pressure plates 4. The scroll plate 5 is placed behind the fixed seat 2. The cylinders 3 control the pressure plates 4 to perform multi-point local clamping on the circumference of the scroll plate 5. Due to the instability of the air pressure of the multiple cylinders 3 and the asynchronous response of the cylinders, the clamping action of the pressure plates 4 cannot be synchronized, causing the scroll plate 5 to be prone to warping and deformation. The reliability and stability of the scroll plate clamping cannot be effectively guaranteed, thus affecting the machining accuracy of the scroll plate. Summary of the Invention
[0003] This invention provides a vacuum adsorption device for processing scroll plates, which solves the problem of deformation of scroll plates caused by mechanical clamping in existing scroll plate fixing devices.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A base with a fixed seat is included. The fixed seat has an air intake hole and multiple scroll plate positioning pin holes. The base is equipped with a vacuum connector. One end of the vacuum connector is connected to the air intake hole, and the other end of the vacuum connector is connected to a vacuum generator. The scroll plate is placed on the fixed seat by aligning with the scroll plate positioning pin holes. A sealing ring is used to enclose the outer circumference of the fixed seat and the scroll plate. In use, when the vacuum generator is turned on, the scroll plate is firmly attracted to the fixed seat and will not move when the milling cutter mills the scroll plate.
[0005] A more specific technical solution than the above-mentioned technical solution may be that the base is provided with three or more of the aforementioned fixing seats.
[0006] Furthermore: a first sealing rubber ring is provided between the sealing ring and the fixed seat, and a second sealing rubber ring is provided between the sealing ring and the outer circle of the vortex disk.
[0007] Furthermore, the fixed base is provided with two positioning pin holes for the scroll plate.
[0008] Furthermore, the vacuum connector and the suction port are connected by a channel.
[0009] Furthermore, a hand-operated three-way switch valve is provided between the vacuum connector and the vacuum generator.
[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects compared with the prior art: By adopting the negative pressure adsorption principle, the scroll plate is firmly adsorbed on the fixed seat through the sealing ring and vacuum generator. The uniform distribution of force on the surface of the scroll plate reduces the deformation of the scroll plate caused by clamping to a range far smaller than the machining tolerance of the scroll plate, effectively ensuring the reliability and stability of the scroll plate fixation, thereby improving the machining accuracy of the scroll plate.

The vortex disk 5 is placed on the fixed seat 2 by aligning the vortex disk positioning pin holes 6, and a sealing ring 12 is used to cover the fixed seat 2 and the vortex disk 5. The base 1 has three or more fixed seats 2; a first sealing rubber ring 13 is provided between the sealing ring 12 and the fixed seat 2, and a second sealing rubber ring 14 is provided between the sealing ring 12 and the outer circle of the vortex disk 5; the fixed seat 2 has two vortex disk positioning pin holes 6; the vacuum connector 8 is connected to the air intake 7 through a channel 11; and a hand-operated three-way switch valve 9 is provided between the vacuum connector 8 and the vacuum generator 10.
[0018] When in use, turn on the vacuum generator 10, and the scroll plate 5 will be firmly attracted to the fixed base 2. It will not move when the milling cutter mills the scroll plate 5. After milling is completed, the scroll plate 5 can be removed by closing the hand-operated three-way switch valve 9.
