Compressor shaft seal mounting apparatus, compressor production apparatus and process

Abstract

The application discloses a compressor shaft seal mounting device, a compressor production device and a process. In the shaft seal mounting process, clamping-oil injection-guide sleeve mounting-shaft seal feeding-shaft seal pressing-clamping-spring mounting-image detection are adopted to complete automatic installation. Through oil injection and oil dropping treatment on the guide sleeve, the resistance and friction can be reduced during the installation of the shaft seal, and damage of the shaft seal during the installation process can be prevented. Finally, the spring mounting is performed. During the spring mounting, the traditional spring mounting only clamps the end holes close to each other, and then the spring contraction is completed. However, after the contraction, the overall structure is twisted, for example, one end is high and the other end is low. The subsequent pressing is required. Then, the positioning body can be used to limit the top of the pneumatic clamping jaw entering into the clamping hole, so that the above problems do not occur after clamping, the pressing process is reduced, and the overall structure is more compact.

Description

Technical Field

[0001] This invention relates to the field of compressor shaft seal installation, specifically to a compressor shaft seal installation device, compressor production equipment, and process. Background Technology

[0002] The compressor shaft seal structure is used to prevent leakage of lubricating oil from the bearings inside the compressor, by blocking the lubricating oil in the inner cavity of the compressor housing.

[0003] In compressor manufacturing, shaft seals and limiting circlips are mostly installed manually, which is inefficient and cannot guarantee quality. A search of CN204639556U—a shaft seal installation and protection fixture for an automotive air conditioning compressor—revealed that the shaft seal protective sleeve and pressure sleeve, which are fitted onto a positioning mandrel, are removed. First, the compressor front cylinder head is positioned into the second mounting hole in the positioning sleeve via the positioning mandrel. Then, the shaft seal protective sleeve is positioned into the shaft hole on the compressor front end cover via the positioning mandrel. Next, the shaft seal is fitted onto the positioning mandrel, allowing it to initially enter the shaft hole on the compressor front cylinder head after passing through the shaft seal protective sleeve. Finally, the pressure sleeve is used to completely press the shaft seal into the shaft hole on the compressor front cylinder head and tighten it. This device requires the positioning mandrel to penetrate the compressor, making it unsuitable for shaft sealing operations at the top end of a variable displacement compressor after the main shaft installation is complete. Therefore, a device is needed that can solve the problem of installing shaft seals on a compressor after the main shaft installation is completed (bottom sealing). Summary of the Invention

[0004] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0005] A compressor shaft seal installation device, comprising:

[0006] One gripping robot is used to grip and fix the compressor.

[0007] The oil injection mechanism is used to spray oil onto the inner wall of the compressor top bore.

[0008] A guide sleeve pick-and-place robot is used to pick up, place, and install guide sleeves onto the shaft head;

[0009] A shaft seal feeding mechanism is used to mount a single shaft seal onto a guide sleeve;

[0010] The first pressing component, with its reciprocating up-and-down motion, is used to press the shaft seal into the compressor.

[0011] Clamping robot arm two, used to clamp and fix the compressor;

[0012] A snap ring pick-and-place robot is used to pick up and place snap rings and press them into the grooves on the inner wall of the compressor top.

[0013] Preferably, the oil injection mechanism includes a vertical linear module, a horizontal rotating module, and an oil nozzle. The vertical linear module is used to adjust the vertical height of the oil nozzle, the horizontal rotating module is used to adjust the horizontal distance between the oil nozzle and the position of the inner hole at the top of the compressor, and the oil nozzle is connected to a lubricating oil tank via a hose for atomizing and spraying lubricating oil.

[0014] Preferably, the fuel injector includes a top cavity and a bottom nozzle;

[0015] The bottom nozzle is hinged to one side of the bottom of the top cavity and the two are connected by a hose. A lubricating oil tank is connected to the side of the top cavity via a hose. The switch valve is set on the hose. A pressurizing body that moves along the inner wall is set in the upper area inside the top cavity. The pressurizing body is used to pressurize and atomize the lubricating oil fed into the top cavity through the pipeline and spray it onto the bearing installation position inside the cylinder.

[0016] A fixed pulley is provided on the side of the top cavity. An elastic rope is connected to the pressurizing body and wound around the fixed pulley for connecting the bottom nozzle. A return spring is connected between the hinged side of the bottom nozzle and the top cavity near the end. When spraying oil, the bottom nozzle changes from facing upward to facing downward.

[0017] Preferably, the snap ring picking and placing robot terminal is equipped with a pneumatic gripper and a positioning body. The pneumatic gripper is used to hold the clamping hole at the end of the snap ring, and the positioning body is used to restrict the upper surface of the snap ring. The positioning body has a semi-circular structure.

[0018] Preferably, the shaft seal feeding mechanism includes a shaft seal feeding gripper, a horizontal linear module, and a vertical linear module. The horizontal linear module is used to adjust the horizontal position of the shaft seal feeding gripper, and the vertical linear module is used to adjust the vertical position of the shaft seal feeding gripper. The shaft seal feeding gripper is a pneumatic gripper.

[0019] Preferably, the shaft seal feeding mechanism further includes a storage rack and a material column, with the material column installed on the storage rack and used to mount the shaft seal.

[0020] Preferably, the shaft seal installation equipment further includes an oil lubrication mechanism, which includes an oil dripper located at the top of the guide sleeve and connected to an oil storage pipe. The oil dripper is used to apply lubricating oil to the surface of the guide sleeve.

[0021] A compressor manufacturing equipment comprises, in sequence, an automatic bearing assembly device, a thrust bearing race assembly device, a main shaft movement detection device, and a shaft seal installation device.

[0022] A compressor manufacturing process includes the following steps:

[0023] 1) Detect the axial movement of the spindle. If the detection meets the standard requirements, proceed to the next process. If it does not meet the standard, proceed to the rework station for rework.

[0024] 2) Shaft seal:

[0025] Clamping:

[0026] Two gripping robotic arms are set up and symmetrically distributed on both sides of the compressor. The gripping robotic arms clamp and fix the compressor.

[0027] Oil spraying:

[0028] The horizontal rotating module rotates the fuel injector to the top of the compressor and aligns it with the inner hole at the top of the compressor. The vertical linear module drives the fuel injector downward to the inner hole at the top of the compressor, where the fuel injector atomizes and sprays fuel.

[0029] Guide sleeve installation:

[0030] The guide sleeve picking and placing robot rotates the guide sleeve from its initial position to the top of the compressor shaft head, and then lowers it to fit onto the shaft head. Before picking and placing the guide sleeve, oil dripping treatment is performed.

[0031] Shaft seal feeding:

[0032] The horizontal linear module adjusts the horizontal position of the shaft seal loading jaws, and the vertical linear module adjusts the vertical height of the shaft seal loading jaws to the outside of the corresponding shaft seal on the material column. After the shaft seal loading jaws clamp the shaft seal, the vertical linear module resets the shaft seal loading jaws to the initial state. The horizontal linear module moves the shaft seal loading jaws to the top of the guide sleeve, and then the vertical linear module puts the shaft seal loading jaws onto the guide sleeve. The vertical linear module and the horizontal linear module are then reset to their initial positions in sequence.

[0033] Shaft seal press fitting:

[0034] The pressing component descends to press the shaft seal into the inner hole at the top of the compressor;

[0035] Clamping:

[0036] The compressor enters the snap ring installation station and is clamped and fixed by the second clamping robot arm;

[0037] Snap ring installation:

[0038] The circlip pick-and-place robot adjusts the position of the pneumatic gripper, moves the bottom surface of the pneumatic gripper and the positioning body to the upper surface of the circlip, and inserts the end of the pneumatic gripper into the clamping hole at the end of the circlip and moves closer to each other to complete the clamping. Then, the circlip pick-and-place robot moves the circlip to the inner hole at the top of the compressor and installs it in the slot on the inner hole wall.

[0039] Image detection:

[0040] The imaging inspection equipment takes pictures from the top for comparison to determine whether the snap ring and shaft seal meet the installation requirements. If they do, the process proceeds to the next step; otherwise, an alarm is triggered and the process is paused.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] This invention automates the shaft seal installation process by employing a series of steps: clamping, oil spraying, guide sleeve installation, shaft seal feeding, shaft seal pressing, clamping, snap ring installation, and image detection. Oil spraying and dripping onto the guide sleeve reduce resistance and friction during installation, preventing damage. Finally, snap ring installation addresses the common problem of traditional snap ring installation where the end clamping holes are simply brought closer together to retract the snap ring. This retraction can lead to structural distortion, such as one end being higher than the other, necessitating subsequent pressing. This invention utilizes a positioning body to restrict the top of the snap ring within the clamping holes using pneumatic grippers, preventing this problem after clamping, reducing the pressing process, and resulting in a more compact overall structure.

[0043] This invention proposes a novel oil injection mechanism. During oil injection, the bottom nozzle, initially angled upwards, rotates to a vertically downward position, preventing oil dripping and contamination of the equipment. The pressurized body reduces the effective volume within the top cavity, ensuring effective oil atomization after descending to its lowest position. After oil injection, the pressurized body immediately rises to recycle excess atomized oil particles back into the top cavity (during the elastic rope's elastic reset process, the angle of the bottom nozzle remains unchanged), preventing droplets from forming inside the compressor's top bore. As the pressurized body continues to rise, the bottom nozzle will be reset by the return spring. After the bottom nozzle is reset, the fuel injector will be reset to its initial position by the horizontal rotation module and the vertical straight module. After the fuel injector is reset, the pressurized body will descend again, and the elastic rope will drive the bottom nozzle to face vertically downward. Keeping the bottom nozzle vertically downward, the pressurized body will continue to descend repeatedly (during the elastic deformation of the elastic rope, the bottom nozzle always maintains a vertical downward angle), which can spray the recovered oil downward and drip it into the reserved oil collection box below.

[0044] This invention uses a top cylinder to drive a lifting plate downwards, which is then pressed down and fixed by a pressure table onto a compressor on a conveyor fixture that has been lifted off the conveyor chain by an upper component. A lower cylinder drives a detection table downwards, pressing the spindle end face down to a predetermined pressure value (the pressure surface of the lower pressure table). Then, a drive motor drives a drive disc via a belt to rotate a rotary wheel, thereby connecting a threaded connector to the spindle's threaded hole. After reaching a predetermined torque, the drive rod end face is pressed and fixed onto the detection plane of the lower pressure table. The lower cylinder then drives the detection table upwards to a predetermined pulling force value. The displacement of the lower pressure table detected by the displacement sensor is the axial movement of the spindle. The lower pressure table presses and fixes the spindle to its lowest position, ensuring that the threaded connector cannot rotate relative to the spindle threaded hole when entering or exiting.

[0045] This invention ensures accurate detection of the spindle's axial movement by performing single-sided detection through top-down pressure and traction. During both the lower cylinder's traction and pressure on the spindle, a mechanical sensor is used to achieve predetermined pressure and tension values, effectively eliminating piston rod displacement that can easily occur when directly using the lower cylinder for pressure and traction, thus improving accuracy. The axial movement of the spindle is detected by a displacement sensor. Furthermore, this invention, in conjunction with a conveying fixture and an upper assembly, enables continuous online detection, improving operational efficiency. Attached Figure Description

[0067] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0068] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0069] Example 1, such as Figure 1 As shown, a compressor shaft seal installation device includes:

[0070] like Figure 8 As shown, the gripping robot arm 70 is used to grip and fix the compressor;

[0071] like Figures 2 to 4 As shown, the oil injection mechanism is used to spray oil onto the inner wall of the compressor top bore.

[0072] like Figure 5 As shown, the guide sleeve pick-and-place robot 80 is used to pick up, place, and install the guide sleeve onto the shaft head, as follows. Figure 5 As shown, it includes a rotary cylinder 81, a telescopic cylinder 82, and a pneumatic gripper 83;

[0073] like Figure 6 As shown, the shaft seal feeding mechanism 90 is used to mount a single shaft seal onto the guide sleeve;

[0074] The pressing component 100, which reciprocates up and down, is used to press the shaft seal into the compressor. The pressing component 100 includes a lifting cylinder and a pressure rod. The lifting cylinder drives the pressure rod to move up and down. When it moves down, it installs the shaft seal into the shaft head. The structure and layout of the pressing component are the same as those of existing pressing components.

[0075] The clamping robot arm 210 is used to clamp and fix the compressor.

[0076] like Figure 7 As shown, the snap ring pick-and-place robot 120 is used to pick up and place snap rings and press them into the groove in the inner wall of the compressor top.

[0077] like Figures 1 to 4 As shown, the oil spraying mechanism includes a vertical linear module 60, a horizontal rotating module 40, and an oil nozzle 50. The oil nozzle 50 has a pump body that draws and atomizes the spraying effect. The vertical linear module 60 is used to adjust the vertical height of the oil nozzle 50, and the horizontal rotating module 40 is used to adjust the horizontal distance between the oil nozzle 50 and the inner hole at the top of the compressor. The oil nozzle 50 is connected to a lubricating oil tank via a hose for atomizing and spraying lubricating oil.

[0078] The fuel injector 50 includes a top cavity 51 and a bottom nozzle 52;

[0079] The bottom nozzle 52 is hinged to one side of the bottom of the top cavity 51 and the two are connected by a hose. A lubricating oil tank is connected to the side of the top cavity 51 via the hose. The switch valve is set on the hose. A pressurizing body 53 that moves along the inner wall is set in the upper area inside the top cavity 51. A secondary cylinder is installed on the top of the pressurizing body 53. The secondary cylinder is installed on the horizontal linear module. The pressurizing body 53 is used to reduce the internal space of the top cavity 51. The pressurizing body 53 is used to pressurize and atomize the lubricating oil fed into the top cavity 51 through the pipeline and spray it downwards to the bearing installation position inside the cylinder.

[0080] A fixed pulley 54 is provided on the side of the top cavity 51. An elastic rope 55 is connected to the pressurizing body 53 and wound around the fixed pulley 54 for connecting the bottom nozzle 52. A return spring 56 is connected between the hinged side of the bottom nozzle 52 near the end and the top cavity 51. When spraying oil, the bottom nozzle 52 changes from facing upward to facing downward.

[0081] The reset spring 56 is provided in two sets located on both sides of the hinge node, and the distance between the reset spring 56 and the mounting node of the top cavity 51 and the axis of the top cavity 51 is equal to the distance between the bottom nozzle 52 and the hinge node of the top cavity 51 and the axis of the top cavity 51.

[0082] A limit block 57 is installed on the top cavity 51 to limit the maximum deflection angle. When the bottom nozzle 52 is at the maximum deflection angle, the axes of the bottom nozzle 52 and the top cavity 51 are collinear.

[0083] By rotating the bottom nozzle from an upward angle to a vertical position during oil injection, oil dripping and contamination of the detection platform are prevented. The pressurized body reduces the effective volume of the top cavity, ensuring effective oil atomization after descending to its lowest position. After oil injection, the pressurized body immediately rises to recycle excess atomized oil particles back into the top cavity (during the elastic rope's elastic reset process), preventing droplets from forming in the cylinder. As the pressurized body continues to rise, the bottom nozzle resets under the action of the reset spring. After the bottom nozzle resets, the injector is reset to its initial position by the horizontal rotation module and the vertical straight module. After the injector resets, the pressurized body descends again, and the elastic rope drives the bottom nozzle to a vertical position. Maintaining the bottom nozzle's vertical downward position, the pressurized body repeats this descent action multiple times (during the elastic rope's elastic deformation process), spraying the recycled oil downwards and dripping it into the pre-reserved oil collection box below (e.g., Figure 1 It is located inside the left rectangular box of the clamping robot arm (70).

[0084] Preferably, such as Figure 7 As shown, the snap ring pick-and-place robot 120 is equipped with a pneumatic gripper 121 and a positioning body 122 at its terminal. The pneumatic gripper 121 is used to grip the clamping hole at the end of the snap ring, and the positioning body 122 is used to restrict the upper surface of the snap ring. The positioning body 122 has a semi-circular structure. The snap ring pick-and-place robot 120 includes a horizontal linear module 1201 and a vertical linear module 1202, which are used to adjust the horizontal position and vertical height of the pneumatic gripper 121, respectively.

[0085] Preferably, such as Figure 6 As shown, the shaft seal feeding mechanism 90 includes a shaft seal feeding gripper 91, a horizontal linear module 92, and a vertical linear module 93. The horizontal linear module 92 is used to adjust the horizontal position of the shaft seal feeding gripper 91, and the vertical linear module 93 is used to adjust the vertical position of the shaft seal feeding gripper 91. The shaft seal feeding gripper 91 is a pneumatic gripper.

[0086] Preferably, the shaft seal installation equipment further includes a lubrication mechanism, which includes an oil dripper located at the top of the guide sleeve and externally connected to an oil storage pipe. The oil dripper is used to apply lubricating oil to the surface of the guide sleeve. (Not shown in the figure.)

[0087] A compressor manufacturing equipment, such as Figures 10 to 13 As shown, the system includes, in sequence, an automatic bearing assembly device, a bearing race assembly device, a spindle movement detection device, and a shaft seal installation device. The spindle movement detection device includes:

[0088] Conveying fixture 10, located on conveying chain 11, is used to support the compressor;

[0089] The upper lifting assembly 20 is used to lift the conveying fixture 10 and separate it from the conveying chain 11.

[0090] The pressing structure 30 is used to vertically press and fix the compressor end cover on the conveying fixture 10. The pressing structure 30 is equipped with a pressing and pulling unit, which includes a pressing and pulling unit and a detection unit. The pressing and pulling unit is used to press down the main shaft to a predetermined pressing pressure value and pull up the main shaft to a predetermined pulling force value. The detection unit is used to detect the axial displacement of the main shaft from the predetermined pressing pressure value to the predetermined pulling force value.

[0091] In this embodiment, the conveying fixture 10 is equipped with a contour structure for holding the compressor. It is conveyed to the inspection station by the conveying chain 11. The upper push assembly 20 pushes it off the conveying chain 11 and enters the inspection point. The lower pressure structure 30 presses down vertically from the top to press the compressor end cover surface on the conveying fixture 10. The lower pressure pulling unit presses down the main shaft end face from the top of the compressor to the bottom position (predetermined lower pressure value) to prevent it from rotating. Then, it pulls the main shaft upward. The inspection unit is used to detect the upward displacement of the main shaft during the upward pulling from the bottom, which is the axial movement of the main shaft.

[0092] The pressing structure 30 includes a mounting frame 31, a top cylinder 32 is mounted on the top of the mounting frame 31, a force sensor 33 is mounted on the piston end of the top cylinder 32, and a lifting plate 34 is mounted through the force sensor 33. The lifting plate 34 is vertically slidably mounted on the mounting frame 31. A surface pressing platform 35 and a vertical rod 36 are mounted on the lifting plate 34. The surface pressing platform 35 is used to press down and fix the compressor end cover, and the vertical rod 36 is used to vertically guide the lifting plate 34. The surface pressing platform 35 has a hollow structure in the middle.

[0093] When the compressor end cover is pressed down, the mounting bracket 31 moves the lifting plate 34 down via the mechanical sensor 33, and the surface pressing table 35 presses and fixes the compressor end cover onto the conveying fixture 10 to prevent the compressor from shifting during subsequent testing.

[0094] The downward pressing and pulling unit includes a lower cylinder 37 mounted on the lifting plate 34. A second mechanical sensor 38 is installed on the piston end of the lower cylinder 37, and a detection platform 39 is connected through the second mechanical sensor 38. The detection platform 39 is vertically slidably fitted on the mounting frame 31. A lower pressing platform 395 is installed on the lower surface of the detection platform 39. The lower pressing platform 395 is used to press down the end face of the spindle until the spindle cannot rotate. The upper surface of the lower pressing platform 395 is a detection plane, and the lower surface is a pressing surface. The pressing surface is used to press down the end face of the spindle. A through hole is provided in the middle of the detection platform 39 and the lower pressing platform 395. An axial threaded pulling structure is installed in the through hole. The axial threaded pulling structure is used to axially thread the spindle threaded hole and press down to tighten the lower pressing platform 395, so that the two are relatively stationary.

[0095] The lower cylinder 37 drives the detection table 39 downward via the mechanical sensor 38. The lower pressure table 395 presses down to fix the end face of the spindle. After the spindle end face is pressed down to the predetermined pressure value, the spindle cannot rotate and the spindle will be lowered to the lowest axial position by the pressure. When the axial threaded pulling structure is threaded to the spindle thread hole, it will press the detection plane of the lower pressure table 395 tightly. The axial threaded pulling structure and the lower pressure table 395 move together and are in a relatively static state.

[0096] The axial threaded pulling structure includes a drive rod 310, a threaded joint 311, and a rotating assembly. The drive rod 310 vertically penetrates the through hole on the testing table 39, and the threaded joint 311 is installed at the bottom. The threaded joint 311 is located in the through hole of the lower pressure table 39. A rotating wheel 312 is fitted on the drive rod 310 and is mounted on the testing table 39. A drive motor 313 is installed on the lifting plate 34. The drive motor 313 drives the drive disk 314 to rotate. The drive disk 314 drives the rotating wheel 312 to rotate via a belt. The drive rod 310 and the rotating wheel 312 can slide vertically relative to each other without rotating relative to each other.

[0097] The rotary disk 312 is provided with a spline hole, and the drive rod 310 is provided with a spline structure that matches the spline hole.

[0098] The drive motor 313 (servo motor) drives the drive disk 314 via a belt, which in turn drives the rotary disk 312 to rotate. The rotary disk 312 drives the drive rod 310 to rotate via a spline hole and spline structure, which in turn drives the threaded joint 311 to enter or exit the spindle thread hole.

[0099] The testing station 39 includes a base plate 391, a top plate 392, and a side plate 393 connecting the base plate 391 and the top plate 392;

[0100] The lower pressure table 395 is fixed to the lower surface of the base plate 391;

[0101] The second mechanical sensor 38 is installed on the upper surface of the top plate 392. The second mechanical sensor 38 is used to detect the upward pulling force and downward pressing force of the spindle.

[0102] A guide sleeve 394 is installed on the lower surface of the top plate 392. The guide sleeve 394 is used to limit the top of the drive rod 310 and slides with it to limit the top of the drive rod 310 from swaying during the rotation.

[0103] The side plate 393 is provided with a guide groove, and the mounting bracket 31 is provided with a vertical guide rail 315 that is adapted to the guide groove.

[0104] The mechanical sensor 238 effectively overcomes the problem of axial displacement of the piston rod affecting detection accuracy due to changes in force at the piston rod end. This embodiment effectively overcomes this drawback and achieves accurate detection.

[0105] Two signal sensors 396 are mounted on the upper surface of the base plate 391 to detect the initial and final position signals of the threaded connection. The two signals facilitate the PLC control of the start and stop of the drive motor 313, thereby controlling the threaded connector 311 to enter or exit the spindle threaded hole.

[0106] The detection unit includes a displacement sensor 341 mounted on the lifting plate 34, which is used to detect the axial displacement of the lower pressure table 395. After the threaded joint 311 enters the threaded hole of the spindle and presses and fixes the lower pressure table 395, the three are combined into a whole. The spindle can be pulled by the lower cylinder 37, which makes it easy to select an object to indirectly detect the axial displacement of the spindle.

[0107] The upper support assembly 20 includes a lifting cylinder 21 and a positioning pin 22. The lifting cylinder 21 is located below the conveying fixture 10 at the inspection station. A support platform 23 is installed on the top of the lifting cylinder 21, and guide rods 24 are vertically installed at the four corners of the support platform 23. The positioning pin 22 is provided on the support platform 23. The positioning pin 22 is used to support the conveying fixture 10 to disengage from the conveyor chain. The positioning pin 22 can be used to laterally position the conveying fixture 10. The bottom of the conveying fixture 10 has a corresponding positioning hole. The support platform 23 is used to lift the conveying fixture 10 to disengage from the conveyor chain 11, realizing online inspection.

[0108] Among them, such as Figures 14 to 21 As shown, the automatic bearing assembly equipment includes a conveyor line A20 and a frame A10 spanning above the conveyor line A20, on which the following are mounted:

[0109] Conveying track A21 is laid on one side of conveyor line A20 and perpendicular to conveyor line A20, and is used for automatic conveying of the bearings required;

[0110] The thickness detection mechanism, located on one side of the conveyor track A21, is used to detect the thickness of the bearing;

[0111] Transfer mechanism one, located at the end of conveying track A21, is used to transport the required bearings on conveying track A21 to the thickness detection mechanism, and its movement direction is set parallel to conveying line A20;

[0112] The second transfer mechanism is located on one side of the thickness detection mechanism and is used to transfer the bearing at the thickness detection mechanism to the pressing station. The direction of movement is perpendicular to the conveyor line A20.

[0113] The oil injection mechanism is located on the side of the conveyor line A20 away from the conveyor track A21. It is used to spray oil on the bearing mounting position in the cylinder body. It can selectively feed in a straight line and the feeding direction is set perpendicular to the conveyor line A20.

[0114] The pressing mechanism, located directly above conveyor line A20, is used to vertically press the bearing into the bearing mounting position inside the cylinder.

[0115] During use, the cylinder body is conveyed by the conveyor line A20. At the pressing station, the pre-set support mechanism pushes it off the conveyor line A20. The vibratory plate at the first end of the conveyor track A21 feeds the bearing, and then the end bearing is squeezed into the transfer mechanism one, which transports it to the thickness detection mechanism for thickness detection. If the thickness meets the requirements, it is transported to the pressing station by the transfer mechanism two for pressing. If the thickness does not meet the requirements, it is centrally processed and placed into the pre-set collection (collection / recycling) box. Before pressing, it is sprayed with oil and then vertically pressed.

[0116] Based on the above embodiments, the following improvements are made: The transfer mechanism includes a slide rail A22 and a slide table A23. The slide rail A22 is arranged parallel to the conveyor line A20. The slide table A23 is slidably fitted onto the slide rail A22. A claw 24 is installed on the slide table A23. The claw A24 is used to support the bearing that has detached from the conveyor rail A21. A supporting boss is provided at the claw opening of the claw A24. The width of the boss is less than or equal to the thickness of the bearing. The slide table A23 and the slide rail A22 form a linear module. The driving method can be a servo motor achieving linear transmission between the two via a lead screw and nut.

[0117] Based on the above embodiment, the following improvements are made: The second transfer mechanism includes a second slide rail A25 and a lifting cylinder A26. The second slide rail A25 is vertically arranged on the conveyor line A20. A second slide table A27 is installed on the second slide rail A25. The lifting cylinder A26 is vertically arranged on the second slide table A27. A pneumatic gripper A28 is installed at the end of the piston rod of the lifting cylinder A26. The pneumatic gripper A28 is used to clamp the bearing after the thickness is detected. The second slide rail A25 and the second slide table A27 form a linear module. The driving method can be a servo motor to achieve linear transmission between the two via a lead screw nut. The lifting cylinder A26 drives the pneumatic gripper A28 to move up and down.

[0118] Based on the above embodiments, the following improvements are made: the thickness detection mechanism includes an upper mounting bracket A29 and a lower mounting bracket A210;

[0119] The upper mounting bracket A29 is equipped with a downward cylinder A211, a detection table A212, and a displacement sensor A213. The output end of the downward cylinder A211 is equipped with a movable frame A214, which is vertically slidably fitted onto the upper mounting bracket A29. The movable frame A214 is spring-loaded with a detection frame A215, which slides vertically relative to the movable frame A214. The displacement sensor A213 is mounted on the movable frame A214 to detect the displacement of the detection frame A215.

[0120] The lower mounting bracket A210 is equipped with a lifting cylinder A216 and a lifting rod A217. The lifting rod A217 is installed at the output end of the lifting cylinder A216. The lifting rod A217 is used to move the bearing upward to the clamping position of the transfer mechanism two.

[0121] As the bearing, delivered by the claw A24, moves between the lifting rod A217 and the inspection frame A215, the lifting rod A217, under the action of the lifting cylinder A216, will move upward, thus holding the bearing in the lifting rod A217 to a predetermined height, which serves as a reference plane. The descending cylinder A211 drives the moving frame A214 downward to the predetermined height, which meets the condition that the inspection table A215 and the supporting area of ​​the lifting rod A217 are in contact and the spring does not deform. Since the lifting rod A217 at the bottom supports the bearing, the inspection table A215 will abut against the upper surface of the bearing and compress the spring relative to the moving frame A214. The displacement sensor A213 will detect the positional change of the inspection table A215 and thus obtain the thickness of the bearing. If the thickness meets the requirements, it will be transported to the pressing station via the transfer mechanism 2. If it does not meet the requirements, it will be transferred to the pre-collected (collection / recycling) box. At the same time, a new bearing will be re-transported by the transfer mechanism 1 and undergo a thickness inspection process until the requirements are met. Thickness testing is to avoid discrepancies in bearing thickness caused by packaging quality inspection by bearing manufacturers within the same batch, as well as discrepancies in bearing thickness caused by errors during the loading process. Screening before pressing can effectively avoid the drawbacks of inconsistent compressor quality caused by this problem.

[0122] Based on the above embodiments, the following improvements are made: the pressing mechanism includes a pressing power element A218 (cylinder) and a base frame A220. The pressing power element A218 is installed on the frame A10 and located directly above the conveyor line A20. A vertical slide A221 is installed at the output end of the pressing power element A218. The vertical slide A221 slides vertically relative to the frame A10. A lifting plate A222, a pressure rod A223, and a displacement sensor A224 are installed on the vertical slide A221. The lifting plate A222 is used to press against the cylinder and slide vertically relative to the vertical slide A221. The pressure rod A223 is used to vertically press the bearing. The displacement sensor A224 is used to detect the displacement from when the lifting plate A222 contacts the cylinder until the bearing pressing is completed.

[0123] The base frame A220 is equipped with a lower cylinder A225, and a socket rod A226 is installed at the output end of the lower cylinder A225. The socket rod A226 is used to hold the bearing.

[0124] The lower cylinder A225 moves the socket rod A226 upward to mount the bearing, the pneumatic gripper A28 releases the bearing and resets, the downward pressing power element A218 drives the vertical slide A221 downward, the lifting plate A222 contacts the cylinder body, and the end face of the pressure rod A223 simultaneously abuts against the upper end face of the bearing.

[0125] The pressure rod A223 presses the bearing down to the bearing installation position inside the cylinder. The displacement sensor A224 detects the bearing pressing depth by detecting the height change of the lifting plate A222 relative to the vertical slide A221.

[0126] When the bearing is pressed in by the pressure rod A223, after the pressure rod A223 contacts the upper end face of the bearing, it moves downward together with the piston rod (socket rod A226) of the lower cylinder A225. At this time, the bearing is in a compressed state. The bearing is vertically lowered to the bearing installation position. The pressure rod A223 can press down on the bearing first. The piston rod of the lower cylinder A225 is pressed inward and retracts. This action will not affect the subsequent use of the lower cylinder A225, about 1-2mm. Then the pressure rod A223 presses the bearing in vertically and quickly. The piston rod of the lower cylinder A225 retracts in sync and quickly, driving the socket rod A226 to return to the initial position.

[0127] Alternatively, the bearing can be vertically press-fitted directly using the pressure rod A223 and the socket rod A226.

[0128] An upper guide sleeve A227 is installed on the frame A10, and the upper guide sleeve A227 is fitted onto the outside of the pressure rod A223. A lower guide sleeve A228 is installed on the base frame A220, and the lower guide sleeve A228 is fitted onto the outside of the socket rod 226.

[0129] The upper guide sleeve A227 is provided with a guide structure one, the lower guide sleeve A228 is provided with a guide structure two, and the pressure rod A223 and the socket rod A226 are both provided with guide pins, and the guide pins are respectively adapted to the corresponding guide structures.

[0130] Both guide structure one and guide structure two include a spiral guide groove A229 and an upper vertical guide groove A2210 that communicates with the spiral guide groove A229.

[0131] By controlling the position of the guide pin within the spiral guide groove A229, the pressure rod A223 and the socket rod A226 move downwards simultaneously, driving the bearing to rotate. This results in a rotary press-fit when the pressure rod A223 and the socket rod A226 press-fit the bearing downwards. In this state, the end connection between the pressure rod A223 and the lower pressing power element A218 is a rotatable connection, and the end connection between the socket rod A226 and the lower cylinder A225 is also a rotatable connection.

[0132] The length of the upper vertical guide groove A2210 of guide structure one is greater than the length of the upper vertical guide groove A2210 of guide structure two. However, when the guide pin is located at the top of the spiral guide groove A229, the guide pins of both are simultaneously at that point, and the pressure rod A223 and the socket rod A226 are in the state of pressing the bearing.

[0133] Based on the above embodiments, the following improvements are made: the oil injection mechanism includes a vertical linear module A30, a horizontal linear module A40, and an oil injector A50. The oil injector A50 has a pump body that extracts and atomizes the spraying effect. The vertical linear module A30 is used to adjust the vertical height of the oil injector A50. The horizontal linear module A40 is used to adjust the horizontal distance between the oil injector A50 and the bearing installation position in the cylinder. The oil injector A50 is connected to a lubricating oil tank via a hose for atomizing and spraying lubricating oil.

[0134] Based on the above embodiments, the following improvements are made: the fuel injector A50 includes a top cavity A51 and a bottom nozzle A52;

[0135] The bottom nozzle A52 is hinged to one side of the bottom of the top cavity A51 and the two are connected by a hose. A lubricating oil tank is connected to the side of the top cavity A51 via the hose. The switch valve is set on the hose. A pressurizing body A53 that moves along the inner wall is set in the upper area inside the top cavity A51. A secondary cylinder is installed on the top of the pressurizing body A53. The secondary cylinder is installed on the horizontal linear module. The pressurizing body A53 is used to reduce the internal space of the top cavity A51. The pressurizing body A53 is used to pressurize and atomize the lubricating oil fed into the top cavity A51 through the pipeline and spray it downwards to the bearing mounting position inside the cylinder.

[0136] A fixed pulley 54 is provided on the side of the top cavity 51. An elastic rope A55 is connected to the pressurizing body 53 and is wound around the fixed pulley A54 for connecting the bottom nozzle A52. A return spring A56 is connected between the hinged side of the bottom nozzle A52 near the end and the top cavity A51. When spraying oil, the bottom nozzle A52 changes from facing upward to facing downward.

[0137] The reset spring A56 is provided in two sets located on both sides of the hinge node, and the distance between the reset spring A56 and the mounting node of the top cavity A51 and the axis of the top cavity A51 is equal to the distance between the bottom nozzle A52 and the hinge node of the top cavity A51 and the axis of the top cavity A51.

[0138] A limit block A57 is installed on the top cavity A51 to limit the maximum deflection angle. When the bottom nozzle A52 is at the maximum deflection angle, the axes of the bottom nozzle A52 and the top cavity A51 are collinear.

[0139] By rotating the bottom nozzle from an upward angle to a vertical position during oil injection, oil dripping and contamination of the detection platform are prevented. The pressurized body reduces the effective volume of the top cavity, ensuring effective oil atomization after descending to its lowest position. After oil injection, the pressurized body immediately rises to recycle excess atomized oil particles back into the top cavity (during the elastic rope's elastic reset process), preventing droplets from forming in the cylinder. As the pressurized body continues to rise, the bottom nozzle resets under the action of the reset spring. After the bottom nozzle resets, the oil nozzle is reset to its initial position by the action of the horizontal and vertical linear modules. After the oil nozzle resets, the pressurized body descends again, and the elastic rope drives the bottom nozzle to a vertical position. By repeatedly descending the pressurized body (during the elastic rope's elastic deformation process), the recycled oil is sprayed downwards and drips into the pre-reserved oil collection box below.

[0140] A compressor manufacturing process includes the following steps:

[0141] 1) Bearing assembly operation

[0142] Bearing loading:

[0143] A vibratory feeder is installed at the beginning of the conveyor track A21. The material is fed through the vibratory feeder at the beginning of the conveyor track A21 and squeezed into the bearing at the end of the conveyor track A24 at the end of the conveyor line A20.

[0144] transport:

[0145] The slide table A23 slides horizontally along the slide rail A22, moving the bearing-supporting claw A24 to the thickness detection point between the lifting rod A217 and the detection table A212;

[0146] Thickness inspection:

[0147] The piston rod of the lifting cylinder A216 drives the lifting rod A217 to move up to the set height. During the upward movement, the bearing inside the claw A24 is supported. At the same time, the lifting cylinder A26 drives the pneumatic gripper to move to the height of the bearing. The downward cylinder A211 drives the moving frame A214 to move down to the set displacement. During the downward movement, the detection frame A215 will contact the bearing and squeeze the spring. The displacement sensor will detect the displacement of the detection frame A215 and thus obtain the bearing thickness value. After the detection is completed, the pneumatic gripper holds the bearing.

[0148] Bearings that do not meet the thickness requirements will be transported to the recycling bin. The above process will be repeated until bearings that meet the thickness requirements are found. Bearings that meet the thickness requirements will then be transported to the next process.

[0149] Oil spraying:

[0150] The horizontal linear module A40 moves the fuel injector A50 above the cylinder block, and the vertical linear module A30 moves the fuel injector A50 down to the bearing mounting position inside the cylinder block to atomize and spray fuel. After completion, the vertical linear module A30 resets the fuel injector A50 to its initial height, and the horizontal linear module A40 resets the fuel injector A50 to its initial position.

[0151] delivery:

[0152] The lifting cylinder A26 drives the pneumatic gripper to move upward to the initial height via the piston rod;

[0153] Slide rail 2A25 and slide table 2A27 move the clamped bearing that meets the thickness requirements to the top of the cylinder;

[0154] The lifting cylinder A26 descends again, and at the same time, the piston rod of the lower cylinder A225 drives the socket rod A226 through the cylinder hole and protrudes from the top, holding the clamped bearing. The pneumatic gripper releases the bearing and first resets it to the initial height, and then resets it to the initial state through slide rail two A25 and slide table two A27.

[0155] Press-fitting:

[0156] The downward-pressing power element A218 drives the vertical carriage A221 downward;

[0157] When the lifting plate A222 contacts the cylinder, the end face of the pressure rod A223 simultaneously abuts against the upper end face of the bearing;

[0158] The pressure rod A223 presses the bearing into the bearing mounting position inside the cylinder, and the displacement sensor A224 is used to detect the bearing press-fit depth.

[0159] When the bearing is pressed in by the pressure rod A223, after the pressure rod A223 contacts the upper end face of the bearing, it moves downward together with the piston rod of the lower cylinder A225, and vertically lowers the bearing to the bearing installation position. The pressure rod A223 presses down on the bearing, and the piston rod of the lifting cylinder A26 retracts inward under pressure. Then the pressure rod A223 vertically and quickly presses in the bearing, and the piston rod of the lifting cylinder A26 retracts synchronously and quickly, driving the socket rod A226 to return to the initial position.

[0160] 2) The bearing housing assembly operation adopts the bearing housing ring assembly method scheme with application number CN202410575614.6;

[0161] 3) Detect the axial movement of the spindle. If the detection meets the standard requirements, proceed to the next process. If it does not meet the standard, proceed to the rework station for rework.

[0162] Online detection of spindle axial movement:

[0163] Compressor delivery:

[0164] The compressor is placed on the conveying fixture 10 and conveyed to the inspection station via the conveying chain 11. The lifting cylinder 21 drives the support platform 23 and the positioning pin 22 to move upward, supporting the conveying fixture 10 to disengage from the conveying chain 11.

[0165] Compressor end cover clamping:

[0166] The top cylinder 32 drives the lifting plate 34 to descend via the mechanical sensor 33, and uses the surface pressure table 35 to press and fix the compressor end cover. The pressure value is 150-190kg, and the pressure value is detected by the mechanical sensor 33.

[0167] Axial movement detection:

[0168] The lower cylinder 37 drives the detection table 39, drive motor 313, drive disk 314, and rotary disk 312 to move downward together via the mechanical sensor 38. The lower pressure table 395 moves down to the pressing surface to press against the end face of the main shaft until it reaches the predetermined pressing pressure value. At this time, the main shaft cannot rotate.

[0169] During the downward movement, the threaded joint 311 abuts against the end of the main shaft and drives the drive rod 310 to move upward relative to the lower pressure table 395.

[0170] The drive motor 313 drives the drive disk 314 to rotate, and the drive disk 314 drives the rotary wheel 312 to rotate via the belt, which drives the threaded joint 311 to engage with the threaded hole of the main shaft until the threaded joint 311 is pressed against the detection plane of the lower pressure table 395 until the predetermined torque value is reached. The lower pressure table 395 is then pressed between the drive rod 310 and the end face of the main shaft.

[0171] The lower cylinder 37 drives the detection table 39, the lower pressure table 395 and the threaded joint 311 to move upward via the second mechanical sensor 38. When it moves upward to the predetermined upward pulling force value, the predetermined upward pulling force value and the predetermined downward pressure value are both detected by the second mechanical sensor 38. The displacement sensor is used to detect the axial displacement of the main shaft from the predetermined downward pressure value to the predetermined upward pulling force value, which is the axial displacement of the lower pressure table 395.

[0172] The drive motor 313 drives the drive disc 314 to rotate in the opposite direction, the drive rod 310 drives the threaded joint 311 to exit the main shaft threaded hole in the opposite direction, the lower cylinder 37 drives the inspection table 39 to move up to the initial position, and the top cylinder 32 drives the lifting plate 34 to move up to the initial position.

[0173] 4) Shaft seal:

[0174] Clamping:

[0175] The clamping robot arm 70 operates. There are two clamping robot arms 70, which are symmetrically distributed on both sides of the compressor. The clamping robot arms 70 clamp and fix the compressor.

[0176] Oil spraying:

[0177] The horizontal rotating module 40 rotates the fuel injector 50 to the top of the compressor and aligns it with the inner hole at the top of the compressor. The vertical linear module 60 drives the fuel injector downward to the inner hole at the top of the compressor, where the fuel injector 50 atomizes and sprays fuel.

[0178] Guide sleeve installation:

[0179] The guide sleeve picking and placing robot 60 rotates the guide sleeve from its initial position to the top of the compressor shaft head, and then lowers it to fit onto the shaft head. Before picking and placing the guide sleeve, oil dripping treatment is performed.

[0180] Shaft seal feeding:

[0181] The horizontal linear module adjusts the horizontal position of the shaft seal loading jaws, and the vertical linear module adjusts the vertical height of the shaft seal loading jaws to the outside of the corresponding shaft seal on the material column. After the shaft seal loading jaws clamp the shaft seal, the vertical linear module resets the shaft seal loading jaws to the initial state. The horizontal linear module moves the shaft seal loading jaws to the top of the guide sleeve, and then the vertical linear module puts the shaft seal loading jaws onto the guide sleeve. The vertical linear module and the horizontal linear module are then reset to their initial positions in sequence.

[0182] Shaft seal press fitting:

[0183] The pressing component 100 presses the shaft seal into the inner hole at the top of the compressor.

[0184] Clamping:

[0185] The compressor enters the snap ring installation station and is clamped and fixed by the clamping robot arm 110;

[0186] Snap ring installation:

[0187] The circlip pick-and-place robot 120 adjusts the position of the pneumatic gripper 121, moves the bottom surface of the pneumatic gripper 121 and the positioning body 122 to the upper surface of the circlip, and inserts the end of the pneumatic gripper 121 into the clamping hole at the end of the circlip and moves closer to each other to complete the clamping. Then, the circlip pick-and-place robot 120 moves the circlip to the inner hole at the top of the compressor and installs it in the slot on the inner hole wall.

[0188] Image detection:

[0189] The image inspection device 130 takes pictures from the top for comparison. The image inspection device 130 is equipped with the same clamping robot 110 as 110 to determine whether the snap ring and shaft seal meet the installation requirements. If they meet the requirements, the process proceeds to the next step. If they do not meet the requirements, an alarm is triggered and the process is paused.
