Description

Technical Field

[0001] This invention relates to the field of scroll compressor manufacturing and assembly technology, and more particularly to an automatic self-aligning locking device and method for scroll compressor support. Background Technology

[0002] A scroll compressor is a high-efficiency, low-noise positive displacement fluid machine whose core consists of meshing moving and stationary scrolls. To ensure stable high-speed operation of the moving scroll, the perpendicularity accuracy between the crankshaft and the main support must be strictly maintained. This parameter directly determines the compressor's operating efficiency, vibration noise, and overall reliability.

[0003] At present, auxiliary supports for scroll compressors are mostly assembled manually or with simple semi-automatic tooling, which has many shortcomings: assembly accuracy depends on human experience, the centering accuracy is unstable, and the product consistency is poor; the centering and locking processes are separated, which is cumbersome and has a long production cycle; uneven tightening torque and improper sequence of multiple screws can easily damage the already aligned accuracy, causing support misalignment, inner hole deformation, and affecting bearing clearance; manual assembly cannot record key data such as centering deviation and locking torque, resulting in poor traceability of the assembly process.

[0004] Therefore, existing assembly processes are insufficient to meet the requirements of high precision, automation, and traceability in mass production. There is an urgent need for a high-precision, fully automated, and process-controllable auxiliary support self-aligning and locking device to solve the above problems. Summary of the Invention

[0005] To address the aforementioned technical problems in existing technologies, such as unstable precision, low assembly efficiency, easy misalignment during locking, and lack of quality traceability, this invention provides an automatic self-aligning and locking device and method for a scroll compressor support. This invention can automatically calibrate the center position of the auxiliary support, accurately ensuring the perpendicularity of the crankshaft to the main support end face. Furthermore, it can perform stable and controllable locking operations while maintaining self-aligning accuracy, effectively improving the assembly precision, product consistency, and assembly efficiency of the compressor auxiliary support.

[0006] The technical means employed in this invention are as follows: An automatic self-aligning and locking device for supporting a scroll compressor includes a base, a frame fixedly installed on the base, a positioning clamp, a pre-compression mechanism, a main lifting mechanism, an automatic self-aligning mechanism, a screw-locking mechanism, and a control system. The positioning clamp is mounted on the base and is used to position and clamp the main support of the semi-finished product compressor; the pre-compression mechanism is mounted on the frame and is coaxial with the positioning clamp, and is used to elastically press the upper end face of the cylinder of the semi-finished product compressor. The main lifting mechanism is mounted on the frame, and the automatic centering mechanism and the screw locking mechanism are both mounted on the main lifting mechanism and rise and fall synchronously with the main lifting mechanism; the automatic centering mechanism is coaxial with the positioning fixture and is used for automatic centering and clamping positioning of the auxiliary support. The control system is electrically connected to the positioning fixture, main lifting mechanism, pre-pressing mechanism, automatic self-aligning mechanism, and screw-locking mechanism.

[0007] Furthermore, the positioning fixture includes a positioning chuck and a positioning platform. The end face of the positioning platform is provided with three sets of gas detection holes and connected to a precision gas flow meter for detecting the fit between the main support end face and the positioning platform reference surface.

[0008] Furthermore, a main lifting mechanism is slidably mounted on the frame via linear guide rails. The main lifting mechanism includes a servo lifting unit and a lifting base plate, and the servo lifting unit drives the lifting base plate to move up and down.

[0009] Furthermore, the pre-compression mechanism includes a pre-compression cylinder, a guide rod, a pressure plate, and an elastic pressure head. The guide rod is slidably mounted on the frame, and its lower end is fixedly connected to the pressure plate. The pressure plate is driven to rise and fall by the pre-compression cylinder. The elastic pressure head is mounted on the pressure plate and is used to elastically contact the upper end face of the cylinder.

[0010] Furthermore, the automatic self-aligning mechanism is fixedly installed on the lifting base plate. The automatic self-aligning mechanism includes a support base, a pneumatic chuck, and self-aligning jaws. The pneumatic chuck is equipped with an XY axis calibration mechanism to correct the center of the self-aligning jaws and ensure that the self-aligning jaws are coaxial with the positioning fixture.

[0011] Furthermore, the screw-locking mechanism is slidably mounted on the lifting base plate via a linear guide rail. The screw-locking mechanism includes a slide block, a torque servo motor, a locking shaft, a hexagonal screwdriver bit, and a lifting cylinder. The torque servo motor is fixedly mounted on the slide block, and its output end is connected to the locking shaft. The bottom end of the locking shaft is fitted with a hexagonal screwdriver bit. One end of the lifting cylinder is fixed to the lifting base plate, and the other end is connected to the slide block. It can independently drive the screw-locking mechanism to lift and lower as a whole, realizing the insertion and removal matching of the hexagonal screwdriver bit and the screw hole. Furthermore, the hexagonal bit and the locking shaft are connected in a longitudinal flexible manner, giving the hexagonal bit the ability to extend and retract elastically in the upper and lower parts.

[0012] The present invention also provides a method for automatic self-aligning and locking of a scroll compressor support, comprising the following steps: S1. The semi-finished compressor is positioned and clamped by the positioning fixture, so that the main support end face is in contact with the positioning platform reference surface; S2. The pre-compression mechanism descends and presses the upper end face of the cylinder of the semi-finished product compressor with the elastic pressure head; S3. The main lifting mechanism descends to the working position, so that the automatic centering mechanism is aligned with the auxiliary support; S4. The screw-locking mechanism descends independently relative to the lifting base plate, and the hexagonal screwdriver bit is inserted into the fixing screw hole of the secondary support and reverses to pre-loosen the fixing screw. S5. The self-aligning jaws of the automatic self-aligning mechanism perform multiple clamping and releasing cycles to complete the automatic self-alignment of the secondary support, and maintain the clamping state after self-alignment is completed. S6. Multiple sets of screw-locking mechanisms simultaneously rotate forward to tighten the fixing screws, tighten them to the set torque, then reverse and rotate forward again to tighten them to the standard torque, and then reverse at a small angle to release the force; S7. The screw-locking mechanism resets, the automatic self-aligning mechanism loosens the secondary support, the main lifting mechanism and the pre-pressing mechanism rise and reset, and the positioning clamp loosens, completing the assembly.

[0013] Furthermore, in step S1, the positioning chuck performs multiple repeated actions of releasing and clamping the outer circle of the main support to achieve precise centering of the main support.

[0014] Furthermore, in step S6, after tightening to the set torque, the torque is reversed by half a turn to one turn, and then the torque is returned to the standard torque by turning the torque forward.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention uses fully automated mechanical self-aligning to replace manual operation, which can achieve micron-level high-precision self-aligning operation, get rid of dependence on operator experience, eliminate manual operation error at the source, and greatly improve the assembly accuracy and product consistency of auxiliary support of compressors in each batch.

[0016] 2. This invention integrates multiple processes such as workpiece positioning, pre-pressure fixing, screw pre-loosening, automatic self-aligning, synchronous locking, stress relief, and reset unloading into one, and completes fully automated operation through the linkage of the control system, which greatly shortens the assembly cycle and adapts to the needs of large-scale mass production.

[0017] 3. The present invention adopts the core process of "precise centering first, full-process clamping and shape preservation, and multi-axis synchronous locking". Synchronous locking is completed while the centering mechanism maintains the precise positioning of the auxiliary support, avoiding the problems of secondary eccentricity and workpiece deformation caused by traditional step-by-step locking and uneven torque, thus ensuring the stability of assembly accuracy.

[0018] 4. This invention can collect and store key process data such as self-aligning deviation data, screw tightening angle, and tightening torque curve in real time throughout the entire assembly process. It can also be bound to the product's unique serial number for archiving, realizing digital control and full-process traceability of the assembly process, and providing data support for product quality analysis, process optimization, and intelligent manufacturing.

[0019] 5. This invention can adapt to the auxiliary support self-aligning and locking operation of scroll compressors of different models and cylinder heights by adjusting the control program parameters, without the need for large-scale tooling changes, and is suitable for the production of multiple product categories, with strong flexible production capabilities.

[0027] This invention provides an automatic self-aligning and locking device for a scroll compressor support, such as... Figure 1-3 As shown, the system includes a rigid base 1, which provides stable support for the entire machine. A positioning fixture 3 is fixedly installed on the top of the base 1 for precise positioning and clamping of the semi-finished compressor 8. The positioning fixture 3 includes a positioning chuck 3.1 and a positioning platform 3.2. The semi-finished compressor 8 is inverted and assembled on the positioning fixture 3. The positioning chuck 3.1 clamps the outer circle of the main support 8.2 to complete radial positioning, and the positioning platform 3.2 completes axial support positioning.

[0028] During the positioning operation, the positioning chuck 3.1 repeatedly opens and closes the outer circle of the main support 8.2 to accurately align and position the center of the main support 8.2. Three sets of gas detection holes are installed on the end face of the positioning platform 3.2. These holes are connected to a precision gas flow meter via pipelines. The gas flow detection principle is used to determine the contact state between the end face of the main support 8.2 and the reference surface of the positioning platform 3.2, ensuring a tight fit and that the perpendicularity of the end face of the main support 8.2 meets assembly requirements. The main support 8.2 is pre-fixed to the cylinder 8.1 of the semi-finished compressor 8 by welding, and the welding process ensures the coaxiality and perpendicularity accuracy of the main support 8.2 and the cylinder 8.1.

[0029] A frame 2 is fixedly installed on the base 1. A main lifting mechanism 4 is slidably mounted on the frame 2 via a linear guide rail. The main lifting mechanism 4 consists of a servo lifting unit 4.1 and a lifting base plate 4.2. The servo lifting unit 4.1 can precisely drive the lifting base plate 4.2 to move up and down, thereby achieving precise adjustment of the working height.

[0030] The lifting base plate 4.2 integrates a screw-locking mechanism 5 and a self-aligning mechanism 6. The screw-locking mechanism 5 is slidably mounted on the lifting base plate 4.2 via a linear guide rail and consists of a slide 5.1, a torque servo motor 5.2, a locking shaft 5.3, a hexagonal screwdriver bit 5.4, and a lifting cylinder 5.5. The torque servo motor 5.2 is fixed to the slide 5.1, and its output end is connected to the locking shaft 5.3. The bottom end of the locking shaft 5.3 is equipped with the hexagonal screwdriver bit 5.4. One end of the lifting cylinder 5.5 is fixed to the lifting base plate 4.2, and the other end is connected to the slide 5.1. It can independently drive the screw-locking mechanism 5 to lift and lower as a whole, realizing the insertion and removal matching of the hexagonal screwdriver bit 5.4 with the screw hole.

[0031] The self-aligning mechanism 6 is fixedly installed on the lifting base plate 4.2 by bolts and can rise and fall synchronously with the main lifting mechanism 4. The self-aligning mechanism 6 includes a support base 6.1, a pneumatic chuck 6.2 and a self-aligning gripper 6.3. The pneumatic chuck 6.2 is assembled on the support base 6.1 through an adjustable structure and has the ability to make fine adjustments and calibrations in the front-back and left-right XY directions. It can accurately correct the center position of the self-aligning gripper 6.3 to ensure high-precision coaxiality with the positioning fixture 3 below. The self-aligning gripper 6.3 moves with the pneumatic chuck 6.2 to clamp and release the auxiliary support 8.7 and complete the automatic self-aligning positioning.

[0032] A pre-compression mechanism 7 is also fixedly mounted on the frame 2. The pre-compression mechanism 7 consists of a pre-compression cylinder 7.1, a guide rod 7.2, a pressure plate 7.3, and an elastic pressure head 7.4. Two sets of pre-compression cylinders 7.1 and four sets of guide rods 7.2 are symmetrically mounted on the left and right sides of the frame 2. The slider of the guide rod 7.2 is slidably engaged with the frame 2, and the lower end of the guide rod 7.2 is fixedly connected to the pressure plate 7.3. The pressure plate 7.3 is equipped with an elastic pressure head 7.4 that can be elastically extended and retracted at the position corresponding to the cylinder 8.1 of the semi-finished product compressor 8. The pre-compression cylinder 7.1 drives the pressure plate 7.3 to rise and fall, and the elastic pressure head 7.4 elastically presses the upper edge of the cylinder 8.1 to achieve overall stable fixation of the workpiece and prevent the workpiece from shaking or shifting during the assembly process.

[0033] The specific workflow of this invention is as follows: The external automatic gripping and unloading mechanism places the semi-finished product compressor 8 upside down on the positioning fixture 3, so that the end face of the main support 8.2 is in contact with the reference surface of the positioning platform 3.2. After the workpiece is initially positioned, the unloading mechanism withdraws from the equipment operation area.

[0034] After the equipment is started, the control system first detects the workpiece's positioning and end-face contact status, and controls the positioning chuck 3.1 to repeatedly loosen and clamp the outer circle of the main support 8.2. After the main support 8.2 is accurately centered, it is kept in a clamped state. Then, the pre-pressing mechanism 7 is controlled to press down, and the elastic pressure head 7.4 elastically presses the upper edge of the cylinder 8.1 to achieve overall fixation of the workpiece.

[0035] Next, the main lifting mechanism 4 drives the self-aligning mechanism 6 and the screw-locking mechanism 5 to descend synchronously to the preset working height, so that the self-aligning jaws 6.3 are aligned with the outer circle of the secondary support 8.7. Then, the screw-locking mechanism 5 descends independently, so that the hexagonal screwdriver bit 5.4 is precisely inserted into the fixed hexagonal bolt hole of the secondary support 8.7. The torque servo motor 5.2 drives the bit to reverse 2-3 revolutions, completely loosening the fixing screw and eliminating the initial tightening stress.

[0036] After the screws are pre-loosened, the pneumatic chuck 6.2 drives the self-aligning jaws 6.3 to perform multiple clamping and loosening cycles, completing the center fine adjustment and precise self-alignment of the secondary support 8.7. After self-alignment, the clamped and shape-preserving state is maintained.

[0037] Subsequently, multiple torque servo motors rotate synchronously forward, driving the screwdriver bit to tighten the fixing screw. Once the tightening torque reaches the preset standard value, the screw is controlled to reverse half a turn to one turn, and then rotated forward again to tighten to the set standard torque, achieving precise pre-tightening of the screw. After tightening, the screwdriver bit is driven to reverse at a small angle to release force, eliminating frictional stress between the screwdriver bit and the screw hole, and preventing disassembly jamming.

[0038] Finally, the pneumatic chuck 6.2 releases the secondary support 8.7, the screw locking mechanism 5, the main lifting mechanism 4, and the pre-pressing mechanism 7 rise and reset in sequence, the positioning chuck 3.1 releases the workpiece, completing the entire self-aligning and locking operation. Finally, the finished workpiece is removed by the external gripping mechanism, and the equipment returns to the initial standby state, waiting for the next operation.

[0039] Finally, 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 foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
