Description

Technical Field

[0001] This application relates to the field of scroll compressor assembly technology, specifically to a tooling for quick positioning and clamping of the scroll plate of a scroll compressor. Background Technology

[0002] The scroll plate is the core moving component of a scroll compressor. Its end face accuracy and tooth profile accuracy directly determine the compressor's performance. Specialized tooling is required for precise positioning and stable clamping during machining and inspection. Currently, clamping is mainly achieved using bolt-type clamping fixtures. However, positioning and tightening rely on manual methods, taking 3-5 minutes per positioning cycle, which is inefficient. Furthermore, manual tightening makes it impossible to effectively control the tightening force, easily leading to uneven clamping force and causing elastic deformation of 0.02-0.05mm on the scroll plate end face. Utility Model Content

[0003] In order to overcome the defects existing in the prior art, the main purpose of this utility model is to provide a tooling for quick positioning and clamping of the scroll plate of a scroll compressor that can perform quick positioning and clamping without damaging the end face of the scroll plate.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for rapid positioning and clamping of the scroll plate of a scroll compressor, comprising:

[0005] Round base;

[0006] Multiple clamping components are fixedly mounted on a circular base and are symmetrical about the center point of the circular base. The clamping ends of the clamping components extend toward the center point of the circular base.

[0007] A circular tray is used to place the vortex disk to be clamped. The circular tray is fixedly located at the center of the circular base, and the center point of the circular tray and the center point of the circular base are on the same vertical line. The radius of the circular tray is the same as the radius of the vortex disk.

[0008] Furthermore, the clamping assembly includes a cylinder base fixedly connected to a circular base, a cylinder fixedly mounted on the upper end of the cylinder base, the telescopic end of the cylinder extending toward the center point of the circular base, and a clamping plate fixedly connected to the telescopic end of the cylinder.

[0009] Furthermore, the clamping plate is an L-shaped clamping plate, the vertical part of the L-shaped clamping plate is fixedly connected to the telescopic end of the cylinder, and the end of the horizontal part of the L-shaped clamping plate is provided with an arc-shaped groove that matches the circumferential surface of the vortex disk.

[0010] Furthermore, the end of the cylinder's telescopic end passes through the center of the vertical part of the L-shaped clamp and is fixedly connected to the L-shaped clamp by bolts.

[0011] Furthermore, the clamping components are at least four sets.

[0012] Furthermore, the circular tray has a circular groove at its center, and the opening of the circular groove is larger than the stepped opening of the groove.

[0013] Furthermore, the circular tray is fixed to the circular base by countersunk screws, or the circular tray and the circular base are an integral structure.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The quick positioning and clamping fixture provided by this utility model places the scroll plate to be clamped and positioned in a circular tray when clamping the scroll plate. Then, multiple clamping components, which are centrally symmetrically arranged on a circular base, are simultaneously activated to clamp the end face of the scroll plate. By clamping simultaneously in multiple directions, it can be ensured that the clamped scroll plate will not be displaced during the clamping process, resulting in more accurate positioning. At the same time, because it clamps from multiple directions and is controlled by cylinders, it is ensured that the scroll plate will not be locally squeezed due to excessive force in one direction during the clamping process. Furthermore, since the clamping is powered by cylinders, the clamping force can be effectively controlled to avoid damage to the scroll plate and improve the efficiency of clamping and positioning.

[0024] Example

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a tooling capable of rapid positioning and clamping, which can protect the scroll plate during clamping and prevent damage to the scroll plate during the clamping process. It is a tooling for rapid positioning and clamping of the scroll plate of a scroll compressor.

[0026] Specifically, this embodiment provides a tooling for rapid positioning and clamping of the scroll plate of a scroll compressor, comprising:

[0027] Circular base 1; In this embodiment, the circular base 1 is made of aluminum alloy. The size of the circular base 1 is designed according to the size of the scroll plate to be clamped. A circular tray 3 is provided at the center of the circular base 1, which is concentric with the circular base 1. The radius of the circular tray 3 is slightly larger than or equal to the radius of the scroll plate 4 to be positioned and clamped. The circular tray 3 can be fixed to the circular base 1 by countersunk screws, or it can be an integral structure with the circular base 1. During operation, the circular tray 3 is used to place the scroll plate 4.

[0028] Multiple clamping components 2 are provided on the circular base 1, and these multiple clamping components 2 are symmetrical about the center point of the circular base 1. The clamping ends of the clamping components 2 extend towards the center point of the circular base 1. In this embodiment, there can be 3, 4, or 6 clamping components 2, depending on the size of the scroll plate 4 to be clamped. In this embodiment, the clamping components 2 are as follows: Figure 3 As shown, there are four clamping components, which are located at the edge of the circular base 1. The telescopic ends of these multiple clamping components extend toward the center of the circular base 1 to ensure that the volute disk 4 can be effectively clamped. During the clamping process, the clamping force on the volute disk 4 extends toward the center of the volute disk. During the clamping process, the volute disk 4 will not be damaged because the clamping force of multiple clamping components 2 does not act on a single point.

[0029] Specifically, during positioning and clamping, the scroll plate 4 to be clamped is placed on the circular tray 3. Because the circular tray 3 has a circular groove at its center, and the opening of this groove is larger than the stepped opening, the scroll plate 4 can be placed into this groove to maintain its positioning. After the scroll plate 4 is placed, multiple clamping components are simultaneously activated. The telescopic ends of these clamping components 2 move synchronously towards the circumferential surface of the scroll plate 4. In this embodiment, the clamping components 2 are all of the same type, and the distance from the telescopic end of each clamping component 2 to the circular base 1 is equal. Therefore, during synchronous activation, the stroke of each clamping component 2 is the same, ensuring consistent clamping force when clamping the scroll plate 4. This prevents deformation caused by different clamping forces from each clamping component during the clamping process.

[0030] In another embodiment, such as Figure 2 The clamping assembly 2 shown includes a cylinder base 201 fixedly connected to a circular base 1. A cylinder 202 is fixedly mounted on the upper end of the cylinder base 201. The telescopic end of the cylinder 202 extends towards the center point of the circular base 1, and a clamping plate 203 is fixedly connected to the telescopic end of the cylinder 202. Specifically, a threaded hole is provided on the circular base 1, and the cylinder base 201 is fixedly connected to the circular base 1 by bolts. Then, the cylinder 202 is fixedly connected to the cylinder base 201 by bolts, completing the fixed connection between the cylinder 2 and the circular base 1. The clamping plate 203 fixedly connected to the telescopic end of the cylinder 202 can cooperate with the circumferential surface of the scroll plate 4 during the clamping process, achieving surface-to-surface contact to achieve clamping. The surface-to-surface cooperation increases the force-bearing area and avoids damage to the scroll plate due to excessive pressure during the clamping process.

[0031] In one embodiment, the clamping plate 203 is an L-shaped clamping plate. The vertical part of the L-shaped clamping plate is fixedly connected to the telescopic end of the cylinder 202. The horizontal end of the L-shaped clamping plate is provided with an arc-shaped groove that matches the circumferential surface of the scroll plate 4. During installation, a step is provided at the end of the telescopic end of the cylinder 202 away from the cylinder 202, and the left end of the step is threaded. The end of the telescopic end of the cylinder 202 is passed through the center of the vertical part of the L-shaped clamping plate. Then, by fixing the fastening nut on the thread at the left end, the L-shaped clamping plate is fixed on the telescopic shaft of the cylinder 202. During clamping, the telescopic end of the cylinder 202 drives the clamping plate 203 to move closer to the scroll plate 4, and the scroll plate 4 is clamped through the arc-shaped groove at the end of the clamping plate 203.

[0032] In this embodiment, multiple cylinders 202 are synchronously controlled by a single air source, ensuring that the cylinders 202 move synchronously during operation and that the clamping force generated during clamping remains consistent. To ensure that the clamping force provided by the cylinders 202 does not damage the scroll plate 4 during clamping, the stroke of the cylinder 202's extension end can be set according to the diameter of the scroll plate 4 during design, ensuring that the scroll plate 4 can be clamped at its maximum stroke without causing compression. Alternatively, a pressure sensor can be provided at the end of the clamping plate 203 to detect the clamping force. When the clamping force meets the clamping standard, a signal is fed back to the valve connecting the cylinder and the air source. The valve closes, the cylinder stops, and the clamping is completed. The above control of the cylinder extension end formation or the control of the cylinder opening and closing by the valve after detection by the pressure sensor is common knowledge or conventional means in this technical field and will not be described in detail here.

[0033] The above embodiments are merely illustrative examples of the present utility model and do not constitute a limitation on the protection scope of the present utility model. All designs that are the same as or similar to the present utility model are within the protection scope of the present utility model.
