Description

Technical Field

[0002] The moving and static disks in a scroll compressor are collectively called scroll disks. The static disk is a fixed involute, and the moving disk is an eccentric revolving and translating involute type. In the compressor, the moving and static scroll disks with two double-function equation profiles are engaged with each other. The common positioning method for scroll disks is pin positioning. The moving and static disks are in clearance fit on the tooling, and the locking screws are used to press the workpiece with a pressing plate to fix the rotation and vertical movement of the moving and static scrolls and achieve the position positioning of processing. However, when using this positioning method for fixing, since it is necessary to manually tighten and loosen the screws, if the force is too large, the workpiece is likely to be deformed, and if the force is too small, the workpiece will rotate, the force control is unstable, and it is laborious and inefficient.

This method is different from the traditional positioning method, and the positioning structure is complex and not easy to operate. Summary of the Utility Model

[0023] Embodiment 1

[0024] Referring to Figures 1 to 2 , which is the first embodiment of the present utility model. This embodiment provides a quick clamping and positioning tooling for dynamic and static scrolls. The dynamic and static scrolls are positioned by an oil cylinder and a hydraulic station. The structure is simple, the operation is easy, and it can ensure the uniformity and stability of the pressing force during positioning, avoid the deformation of the workpiece due to excessive force, and ensure the processing stability of the dynamic and static scrolls.

[0025] A quick clamping and positioning tooling for dynamic and static scrolls includes a dynamic scroll 1, a pin 2, a pressing plate 3, an oil cylinder 4, and a hydraulic station 5; the dynamic scroll 1 is divided into a dynamic scroll 110 and a static scroll 120. Among them, an extending structure is provided in a circle at the bottom of the dynamic scroll 110, and a plurality of pin plates 6 are provided around the static scroll 120. The pin 2 passes through the pin plate 6, and the static scroll 120 is installed on the tooling through clearance fit with the pin 2. In order to position the dynamic scroll 110 and the static scroll 120, when positioning the dynamic scroll 110: the oil cylinder 4 is vertically installed in the tooling where the dynamic scroll 110 is located, and a pressing plate 3 is provided on the connecting surface at the top of the oil cylinder 4. The pressing plate 3 extends out of the structure of the oil cylinder 4 and can cover the extending structure in a circle at the bottom of the dynamic scroll 110. When the oil cylinder 4 moves, it drives the pressing plate 3 to press on the extending structure part of the dynamic scroll 110 to complete the positioning of the dynamic scroll 110; when positioning the static scroll 110: the oil cylinder 4 is connected to a plurality of pin plates 6 around the static scroll 120, and the oil cylinder 4 is connected to the tooling in a "7" shape. The horizontal surface of the "7" shape is arranged above the pin plate 6, and the pressing plate 3 is installed at the bottom of the horizontal surface of the "7" shape. When the oil cylinder 4 moves, the pressing plate 3 is pressed on the pin plate 6 of the static scroll 120 through the lower horizontal surface structure to complete the positioning of the static scroll 120. In addition, the oil cylinder 4 is connected to the hydraulic station 5, and the hydraulic station 5 provides power for the oil cylinder 4. Therefore, the pressing force is controlled by the hydraulic station to ensure the stability of the force.

[0026] It should also be noted in this embodiment that rubber layers are provided on both sides of the pressing plate 3. The oil cylinder 4 transmits the pressing force to the dynamic and static scrolls 1 through the pressing plate 3 to realize the pressing and positioning of the dynamic and static scrolls. The rubber layers on both sides can buffer the pressing force and reduce the risk of deformation of the dynamic and static scrolls.

[0027] According to the above-mentioned dynamic and static scroll quick clamping and positioning tooling, its working principle is as follows: In order to quickly clamp and release the dynamic and static scrolls, the oil cylinder 4 is connected to the dynamic and static scrolls 1 in the above-mentioned manner. When quickly clamping, the hydraulic station 5 is opened to provide a pressing force for the oil cylinder 4, causing the oil cylinder 4 to move up and down. The oil cylinder 4 drives the pressing plate 3 to press the dynamic scroll 110 and the static scroll 120, realizing the positioning of the two. And since the oil cylinder 4 only needs to move up and down, the implementation process of the device is simple and can achieve the effect of quick positioning. When quickly releasing, similarly, only the hydraulic station 5 needs to be opened to make the oil cylinder 4 move up and down, driving the pressing member 3 to release the dynamic and static scrolls 1, completing the release effect. And when the pressing member 3 releases the positioning, because its surface is a rubber layer structure, it can provide a certain buffer when transmitting the pressing force, avoiding workpiece deformation. The positioning method of this embodiment controls the magnitude of the pressing force through the use of the hydraulic station 6, ensuring the uniformity and stability of the force. And the working process of the positioning structure is simple, can achieve the effect of quick release and positioning, improves the production efficiency, and reduces the working intensity of the user.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
