Description

Technical Field

[0001] The utility model relates to the technical field of compressor swash plate manufacturing, in particular to a swash plate thickness detection machine. Background Art

[0002] Automotive air conditioning compressors are typically axial piston compressors. This means the main shaft drives a swash plate in high-speed rotation, which in turn rotates the pistons to achieve compression. The swash plate is connected to the main shaft at a specific angle, and its circumferential edge fits into a groove in the center of the piston. As the main shaft rotates, the swash plate rotates, and the swash plate's edge pushes the pistons in axial reciprocating motion, achieving the compression, exhaust, expansion, and intake steps. The maximum swash plate angle corresponds to the maximum piston travel, while the minimum swash plate angle corresponds to the minimum piston travel.

[0003] The piston contacts the upper and lower surfaces of the swash plate through upper and lower hemispheres housed in its central groove. The piston's central groove and hemispheres are of fixed dimensions, and the spacing between the two hemispheres must match the thickness of the swash plate to ensure good lubrication between the two hemispheres and the swash plate and prevent sticking during reciprocating motion. Therefore, strict requirements are placed on the thickness of the swash plate, requiring it to be tested before the compressor swash plate and piston are assembled into the cylinder. Current swash plate thickness testing equipment is complex, cumbersome, and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It is understood that, in the absence of conflict, some technical means of the various embodiments described herein can be replaced or combined with each other.

[0025] In the description of this utility model, the terms "first," "second," etc., if used, are used solely to distinguish the objects being described and do not convey any order or technical meaning. Therefore, an object defined as "first," "second," etc. may explicitly or implicitly include one or more of such objects. Furthermore, "a," "an," and similar terms do not imply a limitation on quantity, but rather indicate the presence of at least one, and "plurality" means at least two.

[0026] In the description of this utility model specification, reference to "one embodiment" or "some embodiments" means that one or more embodiments of the utility model include a particular feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments", unless otherwise specifically emphasized.

[0027] The utility model provides a slant plate thickness detection machine, referring to Figure 1 In some embodiments, a swash plate thickness detector includes a discharge mechanism 10 and a detection mechanism 20. The discharge mechanism 10 includes a mounting frame 11, a motor 12, a rotating shaft 13, and a discharge plate 14. The rotating shaft 13 is rotatably mounted on the mounting frame 11 in a vertical direction. The motor 12 drives and connects to the rotating shaft 13. The discharge plate 14 is arranged horizontally, with the middle portion of the discharge plate 14 connected to the rotating shaft 13. Positioning seats 15 are provided at each end of the discharge plate 14. The structure of the positioning seats 15 matches the structure of the swash plate 100 to be tested.

[0028] The detection mechanism 20 includes a support seat 21, a movable module 22, a movable frame 23 and a displacement sensor 24. The support seat 21 is arranged on the side of the mounting frame 11, the movable module 22 is arranged on the support seat 21, the movable frame 23 is movably arranged on the movable module 22, and the displacement sensor 24 is arranged at one end of the movable frame 23 facing the discharge plate 14, and the central axis of the displacement sensor 24 is along the vertical direction.

[0029] During use, the rotating shaft 13 is mounted on the mounting frame 11 via bearings and other structures. The swash plate 100 to be tested is placed on the positioning seat 15. The motor 12 drives the rotating shaft 13 to rotate, thereby driving the unloading plate 14 to rotate, causing the swash plate 100 to rotate to the end closest to the detection mechanism 20. The moving module 22 then drives the moving frame 23 toward the swash plate 100, allowing the swash plate 100 to enter the detection area of ​​the displacement sensor 24. The displacement sensor 24 then detects the thickness of the swash plate 100. The above-described swash plate thickness testing machine has a simple and compact overall structure, capable of quickly and accurately testing the thickness of the swash plate, ensuring reliability and improving testing efficiency.

[0030] It should be noted that the drive connection structure between the motor 12 and the rotating shaft 13 can be reasonably designed according to actual conditions. Figure 1 and Figure 2In some preferred embodiments, the motor 12 is horizontally mounted on the side of the mounting frame 11. A first bevel gear 121 is provided at the output end of the motor 12, and a second bevel gear 131 is provided at the bottom end of the rotating shaft 13. The second bevel gear 131 meshes with the first bevel gear 121. When the motor 12 is in operation, it drives the first bevel gear 121 to rotate about its horizontal center axis. The first bevel gear 121, through the meshing structure with the second bevel gear 131, drives the second bevel gear 131 to rotate vertically, thereby driving the rotating shaft 13 to rotate synchronously.

[0031] Reference Figure 1 and Figure 3 In some preferred embodiments, two displacement sensors 24 are provided, one above the other, at one end of the movable frame 23 facing the unloading plate 14. Each displacement sensor 24 has a measurement reference surface, and the distance between the two displacement sensors 24 is H0. When the swash plate 100 enters the detection area of ​​the two displacement sensors 24, the upper displacement sensor 24 can measure the distance H1 between its measurement reference surface and the upper surface of the swash plate 100, while the lower displacement sensor 24 can measure the distance H2 between its measurement reference surface and the lower surface of the swash plate 100. The thickness of the swash plate 100 is then calculated as H3 = H0 - H1 - H2. Using dual displacement sensors for measurement can improve detection accuracy and reduce measurement difficulty. It should be understood that the distance H0 between the measurement reference surfaces of the two displacement sensors 24 should be greater than the maximum value of the thickness range of the swash plate 100 to prevent collision between the swash plate 100 and the displacement sensors 24.

[0032] In some preferred embodiments, the displacement sensor 24 can be a commercially available point spectral confocal displacement sensor, such as that produced by Banshi Intelligent Technology (Shenzhen) Co., Ltd. or Keyence (China) Co., Ltd. A spectral confocal displacement sensor is a high-precision measurement device that uses confocal optics and spectral analysis techniques to measure displacement changes. In a spectral confocal system, after a white light source illuminates the sample, the spectrum of the reflected light is analyzed by a spectrometer to determine the precise position of the sample surface. This system offers high resolution and sensitivity, ensuring accurate measurement of the swash plate thickness.

[0033] Reference Figure 4In some preferred embodiments, the unloading mechanism 10 further includes a portal frame 16. The mounting frame 11 is located inside the portal frame 16. A bearing seat 17 is located at the top center of the portal frame 16. The top end of the rotating shaft 13 is located on the bearing seat 17. The unloading plate 14 is located between the bearing seat 17 and the mounting frame 11. The width of the portal frame 16 is greater than the length of the unloading plate 14. The rotating shaft 13 can drive the unloading plate 14 to rotate inside the portal frame 16. The portal frame 16 and the bearing seat 17 support the rotating shaft 13, thereby ensuring the stability of the rotating shaft 13 and improving the operational reliability of the unloading mechanism 10.

[0034] In the application, the moving module 22 can adopt commercially available linear guide modules, cylinders, electric push rods and other products, which can drive the moving frame 23 to move along the corresponding horizontal direction. Figure 1 In some preferred embodiments, the movable module 22 includes a slide rail 221 and a slider 222. The slide rail 221 is arranged on the support seat 221, the slider 222 is movably arranged on the slide rail 221, and the movable frame 23 is arranged on the slider 222. When the slider 222 moves along the slide rail 221, it can drive the movable frame 23 to move synchronously, so that the displacement sensor 24 is close to or away from the discharge mechanism 10.

[0035] Reference Figure 5 In some other embodiments, the swash plate thickness detector further includes a housing 30, with the discharge mechanism 10 and the detection mechanism 20 disposed within the housing 30. The housing 10 is provided with a discharge port 31, through which at least a portion of the discharge mechanism 10 is exposed. Furthermore, the provision of the discharge port 31 ensures that at least one end of the discharge plate 14 away from the detection mechanism 20 is exposed, facilitating placement of the swash plate 100 on the positioning seat 15 at that end. The detection mechanism 20 needs to be protected within the housing 30 to ensure detection accuracy and operational safety.

[0036] In some preferred embodiments, the swash plate thickness detector further includes a controller 40, which is disposed on the outside or inside of the housing 30. Figure 5 As shown, in one embodiment, the controller 40 is disposed on the outer side of the housing 30. The motor 12, the moving module 22, and the displacement sensor 24 are electrically connected to the controller 40, respectively, and the controller is used to accurately control the working states of the motor 12, the moving module 22, and the displacement sensor 24.

[0037] Furthermore, housing 30 is provided with a display screen 32 and an indicator light 33, each electrically connected to controller 40. Display screen 32 can be used to display the measurement data of each swash plate, and indicator light 33 can be used to indicate the operating status of the swash plate thickness detector. When displacement sensor 24 detects that the swash plate thickness exceeds a set thickness range, controller 40 can also control indicator light 33 to flash as a prompt.

[0038] Furthermore, the housing 30 is provided with an access door 34 and a cooling fan 35. The access door 34 is hinged to the side of the housing 30 and can be opened when necessary to inspect the internal mechanisms of the housing 30. The cooling fan 35 is electrically connected to a controller 40, which controls the operation of the cooling fan 35. The cooling fan 35 is used to dissipate heat from the swash plate thickness detector, preventing mechanical failures caused by excessive heat and ensuring the safety and reliability of the swash plate thickness detector.

[0039] In summary, the utility model provides a swash plate thickness detection machine, which uses positioning plates at both ends of the discharge plate to position the swash plate. The motor can drive the discharge plate to rotate through the rotating shaft, so that the swash plate moves to the side of the displacement sensor. The moving module can drive the displacement sensor close to the swash plate through the moving frame, so that the displacement sensor is used to detect the thickness of the swash plate. The overall structure is simple and compact, and can quickly and accurately detect the thickness of the swash plate, ensuring reliability and improving detection efficiency.

[0040] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
