Description

Technical Field

[0001] This invention relates to scroll plate machining technology, and more particularly to a high-quality scroll plate machining fixture, scroll plate machining equipment, and scroll plate machining method. Background Technology

[0002] The scroll plate is one of the key components of a scroll compressor. It consists of a moving plate and a stationary plate, and the rotation of these plates completes the air intake and compression cycle. The machining quality of the scroll plate determines the overall quality of the scroll compressor. Currently, the profile surface and base circle surface of scroll plates are fixed during machining using clamping and bottom circumferential positioning methods, such as CN210938268U and CN108705351A. However, in some cases, it is impossible to set a positioning structure at the bottom of the scroll plate, meaning that bottom positioning is not feasible. For example, to ensure the mechanical performance and stability of the scroll plate under harsh conditions such as high temperature and high pressure, positioning holes that would affect overall performance are avoided at the bottom. When bottom positioning is not possible, due to the irregular shape of the scroll plate profile, it is impossible to determine the starting point of the tool feed and the machining allowance when machining the base circle surface and profile surface. This can lead to reduced machining accuracy or even scrapping of the scroll plate. Therefore, ensuring accuracy and structural stability during the machining of scroll plates without bottom positioning holes is a current challenge. Current machining equipment lacks a structure and machining method for accurately positioning scroll plates without bottom positioning holes to ensure machining accuracy. Summary of the Invention

[0039] A method for machining a scroll disk is also disclosed, using the aforementioned machining equipment, and the machining steps are as follows:

[0040] Scroll disk profile positioning:

[0041] The scroll plate is placed in the middle of the clamping part, and the profile surface is attached to the arc structure at the end of the movable end. Two scroll plates are arranged on the upper and lower parts of the movable end, and the tail of the profile is attached to the movable end. Before the clamping action of the clamping part is completed, the top of the scroll plate is always pressed down to prevent positional displacement.

[0042] Final positioning of the scroll plate:

[0043] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside, while the moving end is retracted to complete the final positioning of the scroll plate;

[0044] Scroll disk machining:

[0045] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0046] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and a scroll disk machining fixture. The machining steps are as follows:

[0047] Scroll disk profile positioning:

[0048] The scroll plate is placed above the middle of the clamping part, and the movable end is located above the base circle surface. The profile surface is attached to the arc structure at the end of the movable end. Two profiles are arranged on the upper and lower parts of the movable end, and the tail of the profile is attached to the movable end.

[0049] Scroll disk positioning:

[0050] The scroll plate is gradually lowered along the surface of the arc structure. The top of the bottom blind hole of the scroll plate will first contact the upper plate of multiple positioning plates, and then press down on the upper plate. The upper plate will move down along the guide body and move outward at the same time. When the upper plate moves down along the guide body, it will squeeze the reset body inside the guide body. The end of the horizontal push rod is partially exposed on the outside of the upper plate. The horizontal push rod will first contact the inner wall of the bottom blind hole of the scroll plate, and move inward as the scroll plate continues to move down. The vertical pressure rod compresses the spring until the outer wall of the upper plate is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod restricts the top of the lower plate, completing the self-locking and determining the tail position of the profile.

[0051] Final positioning of the scroll plate:

[0052] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside, while the moving end is retracted to complete the final positioning of the scroll plate;

[0053] Scroll disk machining:

[0054] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0055] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and a scroll disk machining fixture. The machining steps are as follows:

[0056] Scroll disk profile positioning:

[0057] The scroll plate is placed above the middle of the clamping part, with the movable end above the base circle. The bullseye bearing is attached to the W area of ​​the scroll plate profile sidewall and compresses the elastic part, so that the guide pin is located on the side of the guide channel close to the bullseye bearing. The scroll plate is rotated, and the tail of the scroll plate profile gradually approaches the rotating sleeve. At the same time, the bullseye bearing will move along the W area of ​​the scroll plate profile sidewall towards the tail of the profile. The elastic part is gradually released. Under the action of the guide pin and the guide channel, the rotating sleeve moves linearly away from the bullseye bearing first, and then drives the rotating sleeve to rotate together with the bullseye bearing, so that the limiting area surrounded by the baffle and the limiting plate faces the tail of the profile. Finally, it continues to move linearly away from the bullseye bearing. The tail of the profile acts on the limiting plate to compress the elastic structure and enter the limiting area. As the linear movement continues, the inner wall of the tail of the profile is attached to the surface of the baffle. At the same time, the limiting plate forms a self-locking under the action of the elastic structure, limiting the angle of the tail of the profile. The switching structure releases the adsorption effect of the adsorption structure.

[0058] Final positioning of the scroll plate:

[0059] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside. At the same time, the movable end retracts and drives the inner rod to move outward relative to the outer sleeve. During the outward extension, the outer sleeve moves linearly away from the scroll plate under the action of the guide post and the deflection channel. Then, under the action of the guide post, the outer sleeve deflects away from the tail of the profile. The switch structure opens the adsorption effect of the adsorption structure, and the inner rod will enter the outer sleeve again. During the process, the outer sleeve will deflect in the opposite direction to the initial angle, completing the final positioning of the scroll plate.

[0060] Scroll disk machining:

[0061] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0062] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and a scroll disk machining fixture. The machining steps are as follows:

[0063] Scroll disk profile positioning:

[0064] The scroll plate is placed above the middle of the clamping part, with the movable end above the base circle. The bullseye bearing is attached to the W area of ​​the scroll plate profile sidewall and compresses the elastic part, so that the guide pin is located on the side of the guide channel close to the bullseye bearing. The scroll plate is rotated, and the tail of the scroll plate profile gradually approaches the rotating sleeve. At the same time, the bullseye bearing will move along the W area of ​​the scroll plate profile sidewall towards the tail of the profile. The elastic part is gradually released. Under the action of the guide pin and the guide channel, the rotating sleeve moves linearly away from the bullseye bearing first, and then drives the rotating sleeve to rotate together with the bullseye bearing, so that the limiting area surrounded by the baffle and the limiting plate faces the tail of the profile. Finally, it continues to move linearly away from the bullseye bearing. The tail of the profile acts on the limiting plate to compress the elastic structure and enter the limiting area. As the linear movement continues, the inner wall of the tail of the profile is attached to the surface of the baffle. At the same time, the limiting plate forms a self-locking under the action of the elastic structure, limiting the angle of the tail of the profile. The switching structure releases the adsorption effect of the adsorption structure.

[0065] Scroll disk positioning:

[0066] The scroll plate is gradually lowered along the surface of the baffle. During the lowering process, the tail of the profile is restricted by the rotation limiting structure and can only move along the axial direction of the movable end. Under the action of gravity, the top of the bottom blind hole of the scroll plate will first contact the upper plate of multiple positioning plates, and then press down on the upper plate. The upper plate will move down along the guide body and move outward at the same time. When the upper plate moves down along the guide body, it will squeeze the reset body inside the guide body. The end of the horizontal push rod is partially exposed on the outside of the upper plate. The horizontal push rod will first contact the inner wall of the bottom blind hole of the scroll plate, and as the scroll plate continues to move down under the action of gravity, it will gradually move inward. The spring is compressed by the vertical pressure rod 8 until the outer wall of the upper plate is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod 8 restricts the top of the lower plate, completing the self-locking and determining the position of the tail of the profile.

[0067] Final positioning of the scroll plate:

[0068] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside. At the same time, the movable end retracts and drives the inner rod to move outward relative to the outer sleeve. During the outward extension, the outer sleeve moves linearly away from the scroll plate under the action of the guide post and the deflection channel. Then, under the action of the guide post, the outer sleeve deflects away from the tail of the profile. The switch structure opens the adsorption effect of the adsorption structure, and the inner rod will enter the outer sleeve again. During the process, the outer sleeve will deflect in the opposite direction to the initial angle, completing the final positioning of the scroll plate.

[0069] Scroll disk machining:

[0070] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0071] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and a scroll disk machining fixture. The machining steps are as follows:

[0072] Scroll disk profile positioning:

[0073] The scroll plate is placed above the middle of the clamping part, with the movable end above the base circle. The tail of the profile first adheres to the movable end. The scroll plate rotates with the tail of the profile as the center. During the rotation, the end of the movable end first adheres to the profile surface, and the free end of the deflection rod then adheres to the profile surface. After the end of the movable end adheres to the profile surface, the tail of the profile moves horizontally along the surface of the movable end. As the scroll plate continues to rotate, the deflection rod deflects relative to the movable end, and the angle between the two gradually increases. The tension spring will gradually stretch, and the top of the deflection rod will drive the sliding pin to move along the moving groove, pressing the end of the pressure rod onto the inner side of the tail of the profile and forming a self-locking mechanism. This limits the angle of the tail of the profile, and the switching structure releases the adsorption effect of the adsorption structure.

[0074] Final positioning of the scroll plate:

[0075] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside. At the same time, the movable end retracts and drives the inner rod to move outward relative to the outer sleeve. During the outward extension, the outer sleeve moves linearly away from the scroll plate under the action of the guide post and the deflection channel. Then, under the action of the guide post, the outer sleeve deflects away from the tail of the profile. The switch structure opens the adsorption effect of the adsorption structure, and the inner rod will enter the outer sleeve again. During the process, the outer sleeve will deflect in the opposite direction to the initial angle, completing the final positioning of the scroll plate.

[0076] Scroll disk machining:

[0077] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0078] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and a scroll disk machining fixture. The machining steps are as follows:

[0079] Scroll disk profile positioning:

[0080] The scroll plate is placed above the middle of the clamping part, with the movable end above the base circle. The tail of the profile first adheres to the movable end. The scroll plate rotates with the tail of the profile as the center. During the rotation, the end of the movable end first adheres to the profile surface, and the free end of the deflection rod then adheres to the profile surface. After the end of the movable end adheres to the profile surface, the tail of the profile moves horizontally along the surface of the movable end. As the scroll plate continues to rotate, the deflection rod deflects relative to the movable end, and the angle between the two gradually increases. The tension spring will gradually stretch, and the top of the deflection rod will drive the sliding pin to move along the moving groove, pressing the end of the pressure rod onto the inner side of the tail of the profile and forming a self-locking mechanism. This limits the angle of the tail of the profile, and the switching structure releases the adsorption effect of the adsorption structure.

[0081] Scroll disk positioning:

[0082] The scroll plate is gradually lowered along the surface of the baffle. During the lowering process, the tail of the profile is restricted by the rotation limiting structure and can only move along the axial direction of the movable end. Under the action of gravity, the top of the bottom blind hole of the scroll plate will first contact the upper plate of multiple positioning plates, and then press down on the upper plate. The upper plate will move down along the guide body and move outward at the same time. When the upper plate moves down along the guide body, it will squeeze the reset body inside the guide body. The end of the horizontal push rod is partially exposed on the outside of the upper plate. The horizontal push rod will first contact the inner wall of the bottom blind hole of the scroll plate, and as the scroll plate continues to move down under the action of gravity, it will gradually move inward. The spring is compressed by the vertical pressure rod 8 until the outer wall of the upper plate is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod 8 restricts the top of the lower plate, completing the self-locking and determining the position of the tail of the profile.

[0083] Final positioning of the scroll plate:

[0084] The CNC system of the processing equipment controls the clamping part to fix the bottom of the scroll plate from the outside. At the same time, the movable end retracts and drives the inner rod to move outward relative to the outer sleeve. During the outward extension, the outer sleeve moves linearly away from the scroll plate under the action of the guide post and the deflection channel. Then, under the action of the guide post, the outer sleeve deflects away from the tail of the profile. The switch structure opens the adsorption effect of the adsorption structure, and the inner rod will enter the outer sleeve again. During the process, the outer sleeve will deflect in the opposite direction to the initial angle, completing the final positioning of the scroll plate.

[0085] Scroll disk machining:

[0086] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0087] Compared with the prior art, the present invention has the following beneficial effects:

[0088] This invention employs a novel positioning fixture, comprising two main parts: a positioning section and a clamping section. The clamping section uses an existing structure, but its main innovation lies in: pre-positioning the angle of the scroll plate's tail section, ensuring that the tail section only moves along the axial direction of the movable end; and finally, after clamping, limiting the position of the movable end along the axial direction, thereby ensuring the precise positioning of the scroll plate. Combined with the CNC center and tool post movement of the machining equipment, this achieves high-quality machining of the profile surface and base circle surface. Each clamping operation only requires ensuring the position and angle of the tail section to guarantee the tool feed start point. Determining the tool feed start point ensures the machining allowance, significantly improving efficiency.

[0089] This invention features a bottom clamping portion on the scroll plate, which clamps and fixes the scroll plate from the outside. A positioning portion is used to accurately determine the angle and position of the tail of the profile within the clamping scroll plate. By accurately determining the angle and position of the tail of the profile, the milling cutter of the subsequent milling mechanism can perform precise cutting, thereby ensuring the accurate machining of the profile surface and the base circle surface.

[0090] The rotary limiting section employs a self-locking structure consisting of a rotating scroll plate, a baffle, a rotating sleeve, a limiting plate, and a bullseye bearing. This structure limits the angle of the scroll plate's tail profile. In conjunction with the initial positioning structure, the scroll plate is aligned with the axis of the clamping part from the bottom. Because the scroll plate's angle is limited by the rotary limiting section beforehand, it only moves along the axis of the movable end during the expansion process of the initial positioning structure. The initial positioning structure performs centering processing, thereby limiting the angle and position of the scroll plate's tail profile. This allows for tool setting and feed processing by the milling mechanism, ultimately achieving high-precision machining.

[0091] The rotation limiting part can also adopt structures such as pressure rods, tension springs, sliding pins, and deflection rods. In use, the scroll plate is placed inside the clamping part. At this time, the tension spring on the deflection rod will be in a stretched state. At this time, the outer sleeve and the end of the deflection rod are both in contact with the profile surface. Rotate the scroll plate until the tail of the profile is in contact with the outer sleeve. While the tail of the profile is rotating, the free end of the deflection rod deflects gradually inside the scroll plate under the action of the tension spring. This drives the sliding pin to gradually press the free end of the pressure rod against the inner wall area of ​​the tail of the profile, thereby achieving self-locking. By holding it, you can continue to control and maintain the position of the scroll plate. The scroll plate is fixed by the clamping part.

[0092] The initial positioning structure employs a bottom-to-inside calibration and centering system, combined with a rotational limiting distribution that restricts the angle of the profile tail, to achieve precise positioning of the scroll plate's angle and position. Specifically, the positioning plate, with its upper and lower plate structure, utilizes the scroll plate's own weight to drive the upper plate downwards while simultaneously expanding outwards to calibrate and center the blind hole on the inner side of the scroll plate's bottom during the lowering process. During calibration and centering, it is only necessary to ensure that the profile tail remains in contact with the movable end; this is essentially a self-locking structure after limiting the tail angle. When the upper plate is in contact with the inner wall of the blind hole, the horizontal push rod within the upper plate acts as a vertical pressure rod to lock and fix the upper and lower plates. After centering and calibration, a self-locking mechanism is formed. Therefore, when clamping the scroll plate from the outside, there is no need to worry about the scroll plate shifting during clamping. This solves the problem of poor machining accuracy caused by the scroll plate contacting the outer circular surface sequentially during clamping, leading to shifts in the profile tail position and angle.

[0093] The structural design of this positioning section addresses three key issues: First, how to solve the problem of inaccurate installation of the scroll plate workpiece due to the lack of positioning holes at the bottom; second, how to solve the problem of inaccurate control of the final profile tail position during clamping of the scroll plate after determining the profile tail angle. This problem arises because it is impossible to accurately ensure that the axis of the scroll plate workpiece coincides with the axis of the clamping part when installing the scroll plate workpiece. In other words, during the clamping process after determining the profile tail angle, the jaws of the clamping part may contact the outer surface of the scroll plate sequentially, which can easily cause the scroll plate position to shift, resulting in a change in the final profile tail angle and / or position; third, how to ensure balanced force on the bottom structure, with the clamping part clamping from the outside and the initial positioning structure tightening and fixing the scroll plate from the inside, thereby ensuring the structural stability of the scroll plate bottom during the milling process.

Clamping part. Detailed Implementation

[0109] Example 1

[0110] like Figure 1 , Figure 2 , Figure 10 , Figure 13 As shown, a high-quality scroll plate machining fixture includes:

[0111] Positioning part 1 is used to limit the angle of the tail of the profile line;

[0112] Clamping part 2, clamping part 2 is used to adaptively adjust the tail position of the regularized line;

[0113] The clamping part 2 clamps the bottom of the scroll disk from the outside, and the clamping part 2 is preferably a pneumatic chuck.

[0114] The positioning part 1 has at least one telescopic structure and a limiting structure for a movable end 11 that can selectively extend and retract. The telescopic structure is preferably a cylinder. The telescopic structure is located on one side of the clamping part 2. The movable end 11 is used to limit the tail angle of the profile, and the limiting structure is used to determine the position of the scroll plate. The movable end 11 is arranged horizontally.

[0115] Example 2

[0116] In Example 1, as Figure 10 , Figure 11 , Figure 12 As shown, one implementation of the positioning part:

[0117] The limiting structure includes a telescopic structure with two movable ends 11 that can selectively extend and retract, the two movable ends 11 being distributed vertically, and the ends may be provided with an arc-shaped structure with an adaptable linear surface.

[0118] The two movable ends 11 are distributed vertically to fix the tail of the profile and the arc structure is used to fit the profile surface to restrict its horizontal position, so that the angle and position of the tail of the profile can be initially positioned. Then, the clamping part 2 clamps the bottom of the scroll plate from the outside to complete the precise positioning effect of the scroll plate.

[0119] Example 3

[0120] Unlike Embodiment 2, when the inventors set an arc-shaped structure with an adaptable linear surface at the end of the movable end 11 for positioning, some problems also exist. For example, when the gripper of the clamping part 2 touches the bottom of the vortex disk first, it will cause the vortex disk to shift to the left.

[0121] like Figures 2 to 9 As shown, the limiting structure includes a rotation limiting structure, which is installed at the end of the movable end 11. The rotation limiting structure includes a guide pin 13, which is installed on the movable end 11. A rotating sleeve 14 is fitted on the outer side of the movable end 11.

[0122] The inner wall of the rotating sleeve 14 is provided with a guide channel 144 suitable for the sliding arrangement of the guide pin 13. The guide channel 144 includes two parallel linear parts and a connecting part connecting the two linear parts. The connecting part is used for the guide pin 13 to cause the rotating sleeve 14 to deflect.

[0123] A bullseye bearing 145 is provided on the side of the rotating sleeve 14 away from the movable end 11. An elastic element is installed inside the rotating sleeve 14, and the two ends of the elastic element are respectively connected to the bullseye bearing 145 and the end of the movable end 11.

[0124] A baffle 141 is provided on the side of the outer circumference of the rotating sleeve 14 away from the movable end 11, and a limit plate 142 is axially slidably installed on the side closer to the movable end 11.

[0125] An elastic structure 143 is installed between the limiting plate 142 and the end of the rotating sleeve 14 near the movable end 11.

[0126] The guide pin 13 moves synchronously with the movable end 11 and can only move along the axial direction. Since the guide channel 144 on the rotating sleeve 14 uses a linear part and a connecting part, when the guide pin 13 passes through the connecting part, it will cause the rotating sleeve 14 to deflect, causing the baffle 141 and the limiting plate 142 to deflect towards the tail of the profile. The bullseye bearing 145 will not cause substantial damage to the profile surface when it moves, and the resistance during the rotation of the rotating sleeve 14 is also small. The limiting plate 142 has a ramp structure on the free end facing the scroll plate, which facilitates the entry of the tail of the profile. The elastic structure 143 provides a flexible action on the limiting plate 142, which facilitates the compression of the tail of the profile when the rotating scroll plate restricts the tail of the profile, until the rotating sleeve 14 and the baffle 141 are stuck at the tail of the profile of the scroll plate, and the angle of the tail of the profile is determined.

[0127] The elastic element includes an elastic part 147, one end of which abuts against the bullseye bearing 145 and the other end is connected to a retainer 146. The retainer 146 is axially movably installed in the rotating sleeve 14, and the retainer 146 and the end of the movable end 11 are in contact via a ball.

[0128] The elastic element is used to fit the bullseye bearing 145 against the profile surface before the profile angle is limited. As the scroll plate rotates, the rotating sleeve 14 gradually approaches the tail of the profile. As the rotation proceeds, the elastic part 147 is compressed. During the compression of the elastic part 147, the guide pin 13 undergoes linear and deflection movements along the guide channel 144, and finally self-locks at the tail of the scroll plate profile. The baffle 146 and the ball are designed to reduce the shear stress during the compression process.

[0129] The movable end 11 includes an outer sleeve 111 and an inner rod 112;

[0130] A guide post 114 is provided on the inner rod 112;

[0131] The outer sleeve 111 is connected to the rotating sleeve 14. The inner part of the outer sleeve 111 is provided with a deflection channel 113, and the deflection channel 113 and the guide post 114 are slidably adapted to each other.

[0132] The inner rod 112 is movably arranged inside the outer sleeve 111, and an adsorption structure 115 is provided between the end of the inner rod 112 and the end of the inner wall of the outer sleeve 111.

[0133] The baffle 141 is provided with a switch structure 116 for controlling the opening and closing of the adsorption function of the adsorption structure 115.

[0134] The inner rod 112 can be the piston rod of a cylinder. The outer sleeve 111 and the inner rod 112 are connected by the guide post 114 and the deflection channel 113. When the movable end 11 retracts, the inner rod 112 retracts, driving the guide post 114 to move along the deflection channel 113. During this process, the outer sleeve 111 will rotate. After rotation, the baffle 141 and the limiting plate 142 will disengage from the tail of the profile. When the tail of the profile contacts the baffle 141, the signal of the opening and closing structure 116 changes, and the adsorption effect of the adsorption structure 115 is lost. When the tail of the profile separates from the baffle 141, the signal of the opening and closing structure 116 changes again, and the adsorption effect of the adsorption structure 115 is regained. The outer sleeve 111 moves relative to the inner rod 112, and finally the inner rod 112 is retracted into the outer sleeve 111.

[0135] Example 4

[0136] Unlike Embodiment 3, when the inventors set an arc-shaped structure with an adaptable linear surface at the end of the movable end 11 for positioning, some problems also exist. For example, when the gripper of the clamping part 2 touches the bottom of the vortex disk first, it will cause the vortex disk to shift to the left.

[0137] like Figure 13 , Figure 14 As shown, the limiting structure includes a pressure rod 1101 installed at the end of the movable end 11. The free end of the pressure rod 1101 is adapted to be pressed and fixed to the inner side of the tail of the profile. The pressure rod 1101 is provided with a moving groove 1102 arranged along the length direction. A sliding pin 1103 is movably arranged in the moving groove 1102. A deflection rod 1104 is rotatably installed on the movable end 11. One end of the deflection rod 1104 is free and the other end is connected to the sliding pin 1103. A tension spring 1105 is connected between the free end of the deflection rod 1104 and the pressure rod 1101.

[0138] For the specific structure here, please refer to... Figure 3 As shown, the movable end 11 includes an outer sleeve 111 and an inner rod 112;

[0139] A guide post 114 is provided on the inner rod 112;

[0140] The outer casing 111 is connected to the deflection rod 1104. The inner part of the outer casing 111 is provided with a deflection channel 113, and the deflection channel 113 and the guide post 114 are slidably adapted to each other.

[0141] The inner rod 112 is movably arranged inside the outer sleeve 111, and an adsorption structure 115 is provided between the end of the inner rod 112 and the end of the inner wall of the outer sleeve 111.

[0142] A switch structure 116 is provided at the end of the pressure rod 1101 to control the opening and closing of the adsorption effect of the adsorption structure 115.

[0143] When in use, the scroll plate is placed inside the clamping part 2. At this time, the tension spring 1105 on the deflection rod 1104 will be in a stretched state. At this time, the ends of the outer sleeve 111 and the deflection rod 1104 are both in contact with the profile surface. Rotate the scroll plate until the tail of the profile is in contact with the outer sleeve 111. While the tail of the profile is rotating, the free end of the deflection rod 1104 gradually deflects inside the scroll plate under the action of the tension spring 1105. This drives the sliding pin 1103 to gradually press the free end of the pressure rod 1101 against the inner wall area of ​​the tail of the profile, thereby achieving self-locking. By holding it, the position of the scroll plate can be maintained and the scroll plate can be fixed by the clamping part 2.

[0144] When the movable end 11 is retracted, the inner rod 112 retracts, driving the guide post 114 to move along the deflection channel 113. During this process, the outer sleeve 111 will rotate. After rotation, the baffle 141 and the limiting plate 142 will disengage from the tail of the profile. When the tail of the profile comes into contact with the opening and closing structure 116 at the end of the pressure rod 1101, the signal of the opening and closing structure 116 changes, and the adsorption effect of the adsorption structure 115 is lost. When the tail of the profile separates from the opening and closing structure 116 at the end of the pressure rod 1101, the signal of the opening and closing structure 116 changes again, and the adsorption effect of the adsorption structure 115 is regained. The outer sleeve 111 moves relative to the inner rod 112, forming the inner rod 112 retracting into the outer sleeve 111.

[0145] Example 5

[0146] In any of the above embodiments, such as Figures 4 to 7 As shown, the positioning part also includes an initial positioning structure, which is located in the middle of the clamping part 2;

[0147] The initial positioning structure includes multiple positioning plates 12 distributed circumferentially;

[0148] The positioning plate 12 includes an upper plate 121, a lower plate 122, and a locking structure;

[0149] The bottom of the upper plate 121 and the top of the lower plate 122 are both sloping structures. A guide body 123 is provided on the top of the lower plate 122. The bottom of the upper plate 121 slides and adapts to the guide body 123 along the sloping structure. A reset body 124 is installed inside the guide body 123.

[0150] The locking structure is used to lock the upper plate 121 and the lower plate 122 immediately after the positioning plate 12 is aligned with the calibrated scroll.

[0151] The bottom blind hole of the scroll plate will first act on the upper plate 121, causing the upper plate 121 to move downward along the guide body 123, and at the same time move outward relative to the lower plate 122, compressing the reset body 124. The reset body 124 is a spring, which tightens the blind hole. After the tightening is completed, the locking structure will lock the upper plate 121 and the lower plate 122.

[0152] The locking structure includes a horizontal guide groove 125 and a vertical guide groove 126 disposed inside the upper plate 121;

[0153] A horizontal push rod 127 is movably installed inside the horizontal guide groove 125. The free end of the horizontal push rod 127 is exposed on the outside of the upper plate 121 and is positioned directly opposite the inner wall of the bottom of the scroll plate.

[0154] A vertical pressure rod 128 is flexibly installed inside the vertical guide groove 126 via a spring. The bottom of the vertical pressure rod 128 can freely enter and exit the bottom of the vertical guide groove 126. The bottom of the vertical pressure rod 128 is exposed at the bottom of the vertical guide groove 126 to lock the upper plate 121 and the lower plate 122.

[0155] A steering structure is provided between the top of the vertical pressure rod 128 and the horizontal push rod 127. The steering structure is used to convert the horizontal movement of the horizontal push rod 127 into the vertical movement of the vertical pressure rod 128.

[0156] The bottom of the vertical pressure bar 128 is provided with a toothed surface, and the top slope structure of the lower plate 122 is provided with a toothed surface corresponding to the position of the toothed surface.

[0157] The steering structure includes a first working surface located at the top of the vertical pressure rod 128 and a second working surface located at the end of the horizontal push rod 127 located in the horizontal guide groove 125. Both the first working surface and the second working surface are inclined structures.

[0158] As the upper plate 121 descends along the guide body 123, the horizontal push rod 127 will first contact the inner wall of the blind hole. As the downward movement continues, the horizontal push rod 127 enters the horizontal guide groove 125. Through the action surface one and the action surface two, the vertical pressure rod 128 compresses the spring, and the bottom is exposed at the bottom of the upper plate 121. The toothed surface locks and fixes the toothed surface of the lower pressure body 122.

[0159] Example 6

[0160] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 2. The machining steps are as follows:

[0161] Scroll disk profile positioning:

[0162] The scroll plate is placed in the middle of the clamping part, and the profile surface is attached to the arc structure at the end of the movable end 11. Two movable ends 11 are arranged on the top and bottom, and the tail of the profile is attached to the movable end 11. Before the clamping action of the clamping part 2 is completed, the top of the downward scroll plate is always kept pressed to prevent positional displacement.

[0163] Final positioning of the scroll plate:

[0164] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside, while the movable end 11 is retracted to complete the final positioning of the scroll plate.

[0165] Scroll disk machining:

[0166] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0167] Example 7

[0168] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 2. The machining steps are as follows:

[0169] Scroll disk profile positioning:

[0170] The vortex disk is placed above the middle of the clamping part, and the movable end 11 is located above the base circle surface. The profile surface is attached to the arc structure at the end of the movable end 11. Two movable ends 11 are arranged above and below, and the tail of the profile is attached to the movable end 11.

[0171] Scroll disk positioning:

[0172] The scroll plate is gradually lowered along the surface of the arc structure. The top of the bottom blind hole of the scroll plate will first contact the upper plate 121 of multiple positioning plates 12, and then press down on the upper plate 121. The upper plate 121 will move down along the guide body 123 and move outward at the same time. When the upper plate 121 moves down along the guide body 123, it will squeeze the reset body 124 inside the guide body 123. The end of the horizontal push rod 127 is partially exposed on the outside of the upper plate 121. The horizontal push rod 127 will first contact the inner wall of the bottom blind hole of the scroll plate, and move inward as the scroll plate continues to move down. The spring is compressed by the vertical pressure rod 128 until the outer wall of the upper plate 121 is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod 128 restricts the top of the lower plate 122, completing the self-locking and determining the tail position of the profile.

[0173] Final positioning of the scroll plate:

[0174] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside, while the movable end 11 is retracted to complete the final positioning of the scroll plate.

[0175] Scroll disk machining:

[0176] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0177] Example 8

[0178] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 3. The machining steps are as follows:

[0179] Scroll disk profile positioning:

[0180] The scroll plate is positioned above the center of the clamping part, with the movable end 11 above the base circle surface. The bullseye bearing 145 is attached to the W region of the scroll plate profile sidewall, compressing the elastic part 147. This causes the guide pin 13 to be located on the side of the guide channel 144 near the bullseye bearing 145. As the scroll plate rotates, the tail of the scroll plate profile gradually approaches the rotating sleeve 14. Simultaneously, the bullseye bearing 145 moves along the W region of the scroll plate profile sidewall towards the tail of the profile. The elastic part 147 is gradually released, and the rotating sleeve 14, under the action of the guide pin 13 and the guide channel 144, moves away from the bullseye bearing 145. The movement causes the rotating sleeve 14 to rotate together with the bullseye bearing 145, causing the limiting area enclosed by the baffle 141 and the limiting plate 142 to face the tail of the profile. Finally, it continues to move linearly away from the bullseye bearing 145. The tail of the profile is compressed by the limiting plate 142 and enters the limiting area. As the linear movement continues, the inner wall of the tail of the profile adheres to the surface of the baffle 141. At the same time, the limiting plate 142 forms a self-locking under the action of the elastic structure 143, limiting the angle of the tail of the profile. The switching structure 116 releases the adsorption effect of the adsorption structure 115.

[0181] Final positioning of the scroll plate:

[0182] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside. At the same time, the movable end 11 retracts and drives the inner rod 112 to move outward relative to the outer sleeve 111. During the outward extension, the outer sleeve 111 moves linearly away from the scroll plate under the action of the guide post 114 and the deflection channel 113. Then, under the action of the guide post 114, the outer sleeve 111 deflects away from the tail of the profile. The switch structure 116 opens the adsorption structure 115 and the inner rod 112 will re-enter the outer sleeve 111. During the process, the outer sleeve 111 will deflect back to the initial angle, completing the final positioning of the scroll plate.

[0183] Scroll disk machining:

[0184] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0185] Example 9

[0186] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 3. The machining steps are as follows:

[0187] Scroll disk profile positioning:

[0188] The scroll plate is positioned above the center of the clamping part, with the movable end 11 above the base circle surface. The bullseye bearing 145 is attached to the W region of the scroll plate profile sidewall, compressing the elastic part 147. This causes the guide pin 13 to be located on the side of the guide channel 144 near the bullseye bearing 145. As the scroll plate rotates, the tail of the scroll plate profile gradually approaches the rotating sleeve 14. Simultaneously, the bullseye bearing 145 moves along the W region of the scroll plate profile sidewall towards the tail of the profile. The elastic part 147 is gradually released, and the rotating sleeve 14, under the action of the guide pin 13 and the guide channel 144, moves away from the bullseye bearing 145. The movement causes the rotating sleeve 14 to rotate together with the bullseye bearing 145, causing the limiting area enclosed by the baffle 141 and the limiting plate 142 to face the tail of the profile. Finally, it continues to move linearly away from the bullseye bearing 145. The tail of the profile is compressed by the limiting plate 142 and enters the limiting area. As the linear movement continues, the inner wall of the tail of the profile adheres to the surface of the baffle 141. At the same time, the limiting plate 142 forms a self-locking under the action of the elastic structure 143, limiting the angle of the tail of the profile. The switching structure 116 releases the adsorption effect of the adsorption structure 115.

[0189] Scroll disk positioning:

[0190] The scroll plate is gradually lowered along the surface of the baffle 141. During the lowering process, the tail of the profile is restricted by the rotation limiting structure, and the angle can only move along the axial direction of the movable end 11. Under the action of gravity, the top of the blind hole at the bottom of the scroll plate will first contact the upper plate 121 of the multiple positioning plates 12, and then press down on the upper plate 121. The upper plate 121 will be pressed down and move outward along the guide body 123. When the upper plate 121 moves down along the guide body 123, it will squeeze the inside of the guide body 123. The end of the horizontal push rod 127 of the reset body 124 is partially exposed on the outside of the upper plate 121. The horizontal push rod 127 will first contact the inner wall of the bottom blind hole of the scroll plate, and as the scroll plate continues to move downward under the action of gravity, it will gradually move inward. The vertical pressure rod 128 compresses the spring until the outer wall of the upper plate 121 is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod 128 restricts the top of the lower plate 122, completing the self-locking and determining the tail position of the profile.

[0191] Final positioning of the scroll plate:

[0192] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside. At the same time, the movable end 11 retracts and drives the inner rod 112 to move outward relative to the outer sleeve 111. During the outward extension, the outer sleeve 111 moves linearly away from the scroll plate under the action of the guide post 114 and the deflection channel 113. Then, under the action of the guide post 114, the outer sleeve 111 deflects away from the tail of the profile. The switch structure 116 opens the adsorption structure 115 and the inner rod 112 will re-enter the outer sleeve 111. During the process, the outer sleeve 111 will deflect back to the initial angle, completing the final positioning of the scroll plate.

[0193] Scroll disk machining:

[0194] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0195] Example 10

[0196] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 4. The machining steps are as follows:

[0197] Scroll disk profile positioning:

[0198] The scroll plate is placed above the middle of the clamping part, and the movable end 11 is located above the base circle surface. The tail of the profile first adheres to the movable end 11. The scroll plate rotates with the tail of the profile as the center. During the rotation, the end of the movable end 11 first adheres to the profile surface, and the free end of the deflection rod 1104 then adheres to the profile surface. After the end of the movable end 11 adheres to the profile surface, the tail of the profile moves horizontally along the surface of the movable end 11. As the scroll plate continues to rotate, the deflection rod 1104 deflects relative to the movable end 11, and the angle between the two gradually increases. The tension spring 1105 will gradually stretch, and the top of the deflection rod 1104 will drive the sliding pin 1103 to move along the moving groove, pressing the end of the pressure rod 1101 onto the inner side of the tail of the profile and forming a self-locking mechanism, limiting the angle of the tail of the profile. The switch structure 116 releases the adsorption effect of the adsorption structure 115.

[0199] Final positioning of the scroll plate:

[0200] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside. At the same time, the movable end 11 retracts and drives the inner rod 112 to move outward relative to the outer sleeve 111. During the outward extension, the outer sleeve 111 moves linearly away from the scroll plate under the action of the guide post 114 and the deflection channel 113. Then, under the action of the guide post 114, the outer sleeve 111 deflects away from the tail of the profile. The switch structure 116 opens the adsorption structure 115 and the inner rod 112 will re-enter the outer sleeve 111. During the process, the outer sleeve 111 will deflect back to the initial angle, completing the final positioning of the scroll plate.

[0201] Scroll disk machining:

[0202] The CNC system of the machining equipment controls the machining tool holder and the tool mounted on it to machine the scroll plate profile and the scroll plate base circle.

[0203] Example 11

[0204] A method for machining a scroll disk includes machining equipment, which includes a milling mechanism and the scroll disk machining fixture of Embodiment 4. The machining steps are as follows:

[0205] Scroll disk profile positioning:

[0206] The scroll plate is placed above the middle of the clamping part, and the movable end 11 is located above the base circle surface. The tail of the profile first adheres to the movable end 11. The scroll plate rotates with the tail of the profile as the center. During the rotation, the end of the movable end 11 first adheres to the profile surface, and the free end of the deflection rod 1104 then adheres to the profile surface. After the end of the movable end 11 adheres to the profile surface, the tail of the profile moves horizontally along the surface of the movable end 11. As the scroll plate continues to rotate, the deflection rod 1104 deflects relative to the movable end 11, and the angle between the two gradually increases. The tension spring 1105 will gradually stretch, and the top of the deflection rod 1104 will drive the sliding pin 1103 to move along the moving groove, pressing the end of the pressure rod 1101 onto the inner side of the tail of the profile and forming a self-locking mechanism, limiting the angle of the tail of the profile. The switch structure 116 releases the adsorption effect of the adsorption structure 115.

[0207] Scroll disk positioning:

[0208] The scroll plate is gradually lowered along the surface of the baffle 141. During the lowering process, the tail of the profile is restricted by the rotation limiting structure, and the angle can only move along the axial direction of the movable end 11. Under the action of gravity, the top of the blind hole at the bottom of the scroll plate will first contact the upper plate 121 of the multiple positioning plates 12, and then press down on the upper plate 121. The upper plate 121 will be pressed down and move outward along the guide body 123. When the upper plate 121 moves down along the guide body 123, it will squeeze the inside of the guide body 123. The end of the horizontal push rod 127 of the reset body 124 is partially exposed on the outside of the upper plate 121. The horizontal push rod 127 will first contact the inner wall of the bottom blind hole of the scroll plate, and as the scroll plate continues to move downward under the action of gravity, it will gradually move inward. The vertical pressure rod 128 compresses the spring until the outer wall of the upper plate 121 is attached to the side wall of the bottom blind hole of the scroll plate. At this time, the bottom of the vertical pressure rod 128 restricts the top of the lower plate 122, completing the self-locking and determining the tail position of the profile.

[0209] Final positioning of the scroll plate:

[0210] The CNC system of the processing equipment controls the clamping part 2 to fix the bottom of the scroll plate from the outside. At the same time, the movable end 11 retracts and drives the inner rod 112 to move outward relative to the outer sleeve 111. During the outward extension, the outer sleeve 111 moves linearly away from the scroll plate under the action of the guide post 114 and the deflection channel 113. Then, under the action of the guide post 114, the outer sleeve 111 deflects away from the tail of the profile. The switch structure 116 opens the adsorption structure 115 and the inner rod 112 will re-enter the outer sleeve 111. During the process, the outer sleeve 111 will deflect back to the initial angle, completing the final positioning of the scroll plate.
