Description

Technical Field

[0002] Scroll compressors utilize the continuous change in a closed container formed by the relative motion of moving and stationary scrolls to compress gas. Since there is no impact friction during the relative motion of the scrolls, scroll compressors offer advantages such as low vibration, low noise, light weight, low energy consumption, long lifespan, continuous and stable gas delivery, reliable operation, and clean gas source. They are widely used in fields such as air conditioning for new energy vehicles.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-8As shown, this is a special clamping device for machining a moving scroll plate. The device includes a base plate 1, and an adjustment mechanism 2 is provided on the top of the base plate 1 for adjusting the machining position and deflection angle of the moving scroll plate, which facilitates machining different positions of the moving scroll plate. A clamping mechanism 3 is installed in the adjustment mechanism 2, and multiple sets of clamping components 4 are connected to the top of the clamping mechanism 3. The moving scroll plate is precisely and stably clamped by the cooperation of the clamping mechanism 3 and the multiple sets of clamping components 4, which facilitates subsequent precision machining.

[0035] like Figure 2 As shown, the aforementioned adjustment mechanism 2 includes a first adjustment seat 21 and a second adjustment seat 22 disposed on both sides of the top of the base plate 1. The first adjustment seat 21 has a cavity inside, a rotary motor 23 is installed at the bottom of the cavity, and a rotary shaft 24 is rotatably mounted at the top of the cavity. The output shaft of the rotary motor 23 is connected to a drive wheel, and a driven wheel is connected to the rotary shaft 24. The drive wheel and the driven wheel are connected by a transmission belt. Furthermore, one end of the rotary shaft 24 passes through the first adjustment seat 21 and is connected to a first rotating disk 25. The second adjustment seat 22 is connected to a second rotating disk 26 at a corresponding position via a rotary shaft. The first rotating disk 25 and the second rotating disk 26 are coaxially arranged, and a connecting rod connects the first rotating disk 25 and the second rotating disk 26. The connecting plate 27 has two symmetrically arranged first slide rails 28 on its top surface. Both first slide rails 28 are inverted T-shaped, and an installation groove is formed between the two first slide rails 28 on the top surface of the connecting plate 27. A moving screw 210 is rotatably arranged in the installation groove, and a moving motor 29 is arranged at one end of the installation groove. The output shaft of the moving motor 29 is fixedly connected to the moving screw 210. A clamping mechanism 3 is threadedly connected to the moving screw 210. The moving screw 210 is driven to rotate by the moving motor 29, and the moving screw 210 drives the clamping mechanism 3 to move laterally. The rotating motor 23 drives the first rotating disk 25 and the second rotating disk 26 to rotate, thereby driving the entire clamping mechanism 3 to deflect, which facilitates the processing of the moving scroll plate at different angles and positions.

[0036] Further such as Figure 3 and Figure 7As shown, the clamping mechanism 3 includes a clamping base 31, and the bottom surface of the clamping base 31 has an inverted T-shaped groove corresponding to the position of the first slide rail 28. The inverted T-shaped groove is slidably connected to the first slide rail 28 and is limited during movement. The bottom of the clamping base 31 also has a movable screw hole 32, and the clamping base 31 is threadedly connected to the movable screw 210 through the movable screw hole 32. Furthermore, the top of the clamping base 31 has a mounting cavity 33, and a positioning base 311 is connected in the middle of the mounting cavity 33. The top surface of the positioning base 311 is flush with the top surface of the clamping base 31, and the clamping base... A guide ring groove 34 is provided at the outer edge of the top surface of the mounting base 31. A movable top plate 35 is slidably connected to the mounting base 31 through the guide ring groove 34. The movable top plate 35 includes an outer ring 350 and an inner ring 352. Multiple sets of connecting bridges 351 are connected between the outer ring 350 and the inner ring 352. The inner diameter of the outer ring 350 is larger than the diameter of the positioning base 311, and the outer diameter of the inner ring 352 is smaller than the diameter of the positioning base 311. At the same time, a guide ring 36 is connected to the bottom surface of the movable top plate 35. The guide ring 36 is adapted to the guide ring groove 34. Furthermore, multiple sets of movable telescopic rods 3 are provided in the mounting cavity 33. 12. The guide rods of multiple sets of movable telescopic rods 312 are connected to the bottom surface of the movable top plate 35. The movable top plate 35 moves up and down by the synchronous extension and retraction of the multiple sets of movable telescopic rods 312. Furthermore, a clamping cylinder 37 is fixedly connected to the top of the positioning base 311. The clamping cylinder 37 has a motion groove 38 at the corresponding position of the connecting bridge 351, so that the movable top plate 35 can move up and down smoothly. The outer diameter of the clamping cylinder 37 is the same as the diameter of the positioning base 311. A mating groove 381 is opened on the inner side of the top of the clamping cylinder 37. The diameter of the mating groove 381 is adapted to the outer diameter of the boss at the bottom of the moving scroll plate. The positioning cylinder 37 is used to initially locate the position of the moving scroll plate. A positioning platform 313 is connected to the top surface of the inner ring 352 inside the clamping cylinder 37. The outer diameter of the positioning platform 313 is adapted to the inner diameter of the boss at the bottom of the moving scroll plate, which further locates the position of the moving scroll plate. The positioning platform 313 moves with the moving top plate 35 to fix the moving scroll plate, realizing the precise lateral positioning of the moving scroll plate and avoiding the offset during clamping, which would affect the accuracy of the machining. Multiple sets of fixing plates 39 are connected to the top outer side of the clamping cylinder 37. The multiple sets of fixing plates 39 are symmetrically distributed around the center of the clamping cylinder 37.

[0037] Further, such as Figures 3-8 As shown, the clamping assembly 4 includes a clamping block 43 disposed on the fixed plate 39 and a moving base 41 disposed at a corresponding position on the movable top plate 35. The bottom surface of the clamping block 43 has a movable groove 435, and a second slide rail 310 is correspondingly mounted on the top surface of the fixed plate 39. The second slide rail 310 is slidably connected to the movable groove 435, allowing the clamping block 43 to slide laterally on the fixed plate 39. An inclined guide post 42 is mounted on the moving base 41, the inclined guide post 42 being inclined outwards, and as shown... Figure 4As shown, a clearance groove 391 is provided in the middle of the fixed plate 39, and the inclined guide post 42 is set through the clearance groove 391. The size of the clearance groove 391 is larger than the lateral movement distance of the inclined guide post 42 when it rises or falls. The moving base 41, the inclined guide post 42, the fixed plate 39 and the clamping block 43 are matched. The clamping block 43 is provided in the middle of the moving inclined groove 431. The moving inclined groove 431 is adapted to the inclined guide post 42, and the inclined guide post 42 slides in the moving inclined groove 431 to drive the clamping block 43 to move laterally to achieve the clamping effect. Furthermore, the top of the clamping block 43 near the moving vortex disk is provided with a connecting mounting hole 1 433 and mounting hole 2 434. The mounting hole 1 433 and mounting hole 2 434 are fitted with a fixed pressure rod 44. The tail of the fixed pressure rod 44 is fitted with the inclined guide post 42 to achieve vertical fixation.

[0038] Further such as Figure 5 and Figure 6 As shown, a frustum 441 is provided on the side of the fixed pressure rod 44 near the inclined guide post 42, and a spring 45 is sleeved on the fixed pressure rod 44. One end of the spring 45 abuts against the frustum 441, and the other end abuts against the bottom surface of the mounting hole 434. At the same time, a positioning groove 421 is opened at the upper end of the inclined guide post 42 corresponding to the fixed pressure rod 44. The tail of the fixed pressure rod 44 is set in the positioning groove 421. Furthermore, a pressing inclined surface 442 is opened on the lower side of the tail of the fixed pressure rod 44, which is used to press the fixed pressure rod 44 when the inclined guide post 42 moves upward, so that the fixed pressure rod 44 moves forward. A mating inclined surface 443 is provided on the upper side of the part. The inclination angle of the mating inclined surface 443 is consistent with that of the inclined guide post 42, which facilitates the movement of the inclined guide post 42. A fixing surface 444 is provided on the lower side of the front end of the fixing pressure rod 44. The fixing surface 444 is flush with the top surface of the clamping arc surface 432 at the front end of the clamping block 43, which realizes the vertical fixation of the moving scroll plate. Furthermore, a guide surface 445 is provided at one end of the fixing surface 444 to guide the fixing pressure rod 44 when it moves laterally forward to press the surface of the braking scroll plate, so as to avoid the fixed pressure rod 44 from running poorly due to the height difference on the surface when the moving scroll plate is clamped.

[0039] Furthermore, each of the multiple clamping blocks 43 has a clamping arc surface 432 on its clamping side. The multiple clamping arc surfaces 432 work together to clamp and fix the side of the moving scroll plate. Furthermore, the clamping arc surfaces 432 are provided with machining textures to improve friction and enhance the stability of the clamping.

[0040] Working principle of the invention:

[0041] The moving scroll plate is placed on the clamping cylinder 37, so that the boss at the bottom of the moving scroll plate is assembled with the mating groove 381. Multiple sets of moving telescopic rods 312 are activated to drive the moving top plate 35 to move upward. The moving top plate 35 drives the positioning cylinder 313 to move upward and is locked in the boss at the bottom of the moving scroll plate. At the same time, the moving top plate 35 drives multiple moving bases 41 to move upward. The moving bases 41 drive the inclined guide column 42 to move upward. The upward movement of the inclined guide column 42 drives the clamping block 43 to move laterally inward. Multiple clamping blocks 43 clamp the moving scroll plate. Simultaneously, the inclined guide column 42 moves upward, pushing the fixed pressure rod 44 to extend. After the fixed pressure rod 44 extends to its limit distance, the inclined guide column 42 continues to move. The extension distance of the fixed pressure rod 44 remains constant. As the clamping block 43 moves, the moving scroll plate is fixed in the vertical direction.

[0042] When the machining position needs to be adjusted, the moving motor 29 is started to drive the moving screw 210 to rotate, and the moving screw 210 drives the moving scroll plate to move laterally to adjust the machining position; when the machining deflection angle needs to be adjusted, the rotating motor 23 is started to drive the first rotating disk 25 and the second rotating disk 26 to rotate, and the first rotating disk 25 and the second rotating disk 26 drive the moving scroll plate to rotate and move the angle, so as to facilitate machining at different positions.
