Description

Technical Field

[0001] This utility model relates to the field of vortex disk manufacturing technology, specifically to a vortex disk positioning stage. Background Technology

[0002] The scroll plate (also known as a spiral scroll) is the core component of a scroll compressor. It consists of a moving plate and a stationary plate, which mesh together via involute profiles to achieve the functions of fluid intake, compression, and discharge. In industrial applications, scroll plates must meet high precision (micrometer-level) and low wear requirements; their profile accuracy directly affects compressor efficiency. The core of scroll plate positioning lies in ensuring precise meshing of the moving and stationary plate profiles. Currently, visual inspection is the primary method used for positioning in the market.

[0003] For example, patent application CN201420812247.9, with authorization announcement date 20150513, discloses a moving scroll positioning device for installing a cross-ring vacuum compressor. It includes a moving scroll, a base, a crankshaft mounted on the base, with the front end of the crankshaft installed at the center of the moving scroll. A positioning plate is installed on the back of the moving scroll, and an eccentric shaft is installed between the moving scroll and the base. One end of the eccentric shaft is installed on the base, and the other end passes through the positioning plate and is installed in the mounting hole of the moving scroll. This utility model, by setting up a positioning plate, greatly simplifies the installation process and improves installation efficiency.

[0004] Traditional visual inspection requires complex algorithms and precision optical equipment, which is costly and susceptible to interference from ambient light and oil. Furthermore, traditional visual inspection equipment has a large support structure, making it difficult to adapt to compact production lines. Therefore, there is an urgent need to design a scroll plate positioning stage to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a scroll plate positioning stage to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vortex disc positioning stage includes a support rod assembly, a lifting support assembly, a clamping assembly, and a limiting assembly. The lifting support assembly is bolted to one side of the support rod assembly. The clamping assembly and the limiting assembly are respectively disposed on the lifting support assembly. The lifting support assembly includes a connecting frame. A main board is bolted to one side of the connecting frame, and a lower support plate is bolted to the outer wall of one side of the main board. An adjusting cylinder is bolted to the bottom side of the lower support plate. An upper limiting plate located above the lower support plate is bolted to the outer wall of one side of the main board. A guide rail is bolted to one side of the main board, and a mounting bracket is slidably connected to the guide rail. The output end of the adjusting cylinder is bolted to the mounting bracket. A bearing groove is formed on one side of the mounting bracket, and a spring telescopic rod is mounted inside the bearing groove via a bearing. An annular pressure block is bolted to the output end of the spring telescopic rod. A vortex line detection sensor is bolted to one side of the mounting bracket. Buffer rods are bolted to the outer walls of one side of the lower support plate and the upper limiting plate. An installation opening is formed on the top side of the lower support plate.

[0008] Furthermore, the fixture assembly includes a base, which is bolted inside the mounting port, and a workpiece platform is mounted on the top of the base via a bearing, with a scroll workpiece placed inside the workpiece platform.

[0009] Furthermore, a rotary motor is bolted to the bottom of the base, and a reduction mechanism is provided at the output end of the rotary motor. The reduction mechanism is installed together with the bottom of the workpiece platform via a coupling.

[0010] Furthermore, the limiting component includes a cylinder seat, which is bolted to one side of the top of the lower support plate, and a double output rod cylinder is bolted to one side of the top of the cylinder seat.

[0011] Furthermore, the output end of the dual output rod cylinder is bolted to a support frame, and a mounting seat is bolted to one side of the top of the support frame, with a ball-head push rod inserted inside the mounting seat.

[0012] Furthermore, the support rod assembly includes a base plate, a profile rod is bolted to the top center of the base plate, and a multi-position air source valve is bolted to one side of the profile rod. The multi-position air source valve is connected to the regulating cylinder and the dual output rod cylinder respectively through pipelines.

[0013] Furthermore, two reinforcing plates are bolted to the outer walls on both sides of the top of the base plate, and one end of each reinforcing plate is bolted to the outer walls of the profile rod on all four sides.

[0014] In the above technical solution, the vortex disk positioning stage provided by this utility model has the following advantages:

[0015] (1) This utility model directly detects the physical change of the vortex line from existence to non-existence through the vortex line sensor, and detects the displacement of the edge of the profile line when the vortex workpiece rotates. It avoids the defects of the vision system being sensitive to light and oil stains, reduces hardware costs, and the spring telescopic rod drives the ring pressure block to press the workpiece. With the help of the buffer rod to absorb vibration, it ensures the stability of the pressing process, avoids repeated manual adjustments, improves positioning efficiency, and solves the problem of frequent manual intervention.

[0016] (2) The rotary motor and reduction mechanism of this utility model drive the workpiece platform to rotate dynamically and realize closed-loop positioning. During the rotation of the vortex workpiece, the vortex line detection sensor captures the change in profile position in real time. Combined with the lifting control of the mounting frame by the adjustment cylinder, the rotation-detection-pressing calibration process is automatically completed, which significantly improves the meshing accuracy and solves the problem of lack of real-time dynamic calibration.

[0017] (3) The ball head top rod of this utility model has a spherical contact design that adapts to the curvature of the vortex edge, accurately inserts into the profile groove, and the dual output rod cylinders push the support frame on both sides in sync, eliminating the deviation caused by single-point force application, ensuring the symmetry of the limit position, and overcoming the defects of insufficient stability of traditional limit position.

[0018] (4) The single aluminum profile rod of this utility model replaces the traditional frame, which reduces the space occupied. In addition, the multi-position air source valve centrally controls the air path of the regulating cylinder and the double output rod cylinder, which simplifies the pipeline layout. Moreover, the reinforcing plate enhances the torsional stiffness of the profile rod, ensuring the structural stability during high-precision positioning, and solving the problem of the large structure being difficult to adapt to compact production lines.

When the groove is being grooved, the dual-output rod cylinder 28 pushes the ball-head push rod 31 through the support frame 29. The spherical contact design of the ball-head push rod 31 adapts to the curvature of the scroll edge and precisely engages in the profile groove. The support rod assembly 1 includes a base plate 5. A profile rod 6 is bolted to the top center of the base plate 5, and a multi-position air source valve 8 is bolted to one side of the profile rod 6. The multi-position air source valve 8 is integrated on the profile rod 6 and centrally controls the air path of the regulating cylinder 12 and the dual-output rod cylinder 28, simplifying the pipeline layout. The multi-position air source valve 8 is connected to the regulating cylinder 12 and the dual-output rod cylinder 28 through pipelines.

[0039] Working principle: The scroll plate workpiece 26 is placed on the workpiece platform 25 of the fixture assembly 3. Then, the adjusting cylinder 12 of the lifting support assembly 2 is activated, and its output end pushes the mounting frame 15 to move vertically downward along the guide rail 13, causing the spring telescopic rod 17 and the annular pressure block 18 to contact the surface of the scroll plate workpiece 26. During this process, the elastic deformation of the spring telescopic rod 17 adapts to the workpiece height deviation, and the buffer rod 19 absorbs the impact of the pressing, avoiding rigid collision damage to the workpiece. Subsequently, the rotary motor 23 of the fixture assembly 3 drives the workpiece platform 25 to rotate through the reduction mechanism 24, causing the scroll plate workpiece 26 to rotate uniformly around the axis. During this process, the vortex detection sensor 21 on the mounting frame 15... The displacement of the scroll profile edge is monitored in real time. When the scroll profile changes from a raised area to a recessed area, the profile engagement reference point is determined. The sensor signal is fed back to the external control system, which triggers the adjusting cylinder 12 to fine-tune the height of the mounting bracket 15, ensuring that the pressing force of the annular pressure block 18 matches the position of the workpiece. At the same time, the dual output rod cylinder 28 of the limiting component 4 receives the control signal and synchronously drives the two side support brackets 29 to move towards the center of the workpiece. The ball head top rod 31 is inserted into the mounting seat 30 at the top of the support bracket 29. Its spherical surface contacts the edge of the scroll workpiece 26, adapts to the curvature of the profile, and is locked into the groove, ensuring that the position of the scroll workpiece 26 is locked in the horizontal plane.
