Description

Technical Field

[0001] This invention relates to equipment for air compressor production, and more particularly, to an air compressor assembly line. Background Technology

[0002] Air compressors play a vital role in modern industry, acting as machines that compress gas into high-pressure gas. During operation, gas is compressed using a piston or screw and then stored in a pressure vessel. When the stored air is needed, it is released through pipelines for various applications. However, the assembly of air compressor heads often requires manual labor, resulting in low automation and low assembly efficiency. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an air compressor assembly production line, which has the advantages of high automation and high assembly efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: an air compressor assembly production line, including a material conveying track and a plurality of material bearing plates arranged sequentially on the material conveying track, wherein the material conveying track is used to drive the material bearing plates to move along the length direction of the material conveying track;

[0005] Along the moving direction of the material carrying plate, the side of the material conveying track is sequentially equipped with a rotor and cam box assembly workstation, a cam box top cover installation workstation, a cam box fan blade installation workstation, and a fan blade mesh cover installation workstation. The rotor and cam box assembly workstation can first install bearings at both ends of the rotor, then press the rotor into the inside of the cam box, and finally place the cam box on top of the material carrying plate. The cam box top cover installation workstation is used to press and fix the top cover to the cam box placed on top of the material carrying plate with bolts. The cam box fan blade installation workstation is used to install fan blades at both ends of the cam box and lock the fan blades to the ends of the rotor with snap rings. The fan blade mesh cover installation workstation is used to snap mesh covers on both ends of the cam box.

[0006] The above technical solutions allow for the transfer of incomplete air compressor heads via a material support plate, replacing manual handling by workers. The rotor and cam box assembly workstation first installs bearings at both ends of the rotor, then presses the rotor into the cam box, and finally places the cam box on top of the material support plate. The cam box top cover installation workstation secures the top cover to the cam box placed on top of the material support plate using bolts. The cam box fan blade installation workstation installs fan blades at both ends of the cam box and locks them to the ends of the rotor using snap rings. The fan blade mesh cover installation workstation attaches mesh covers to both ends of the cam box. In summary, the above production line can automatically assemble air compressor heads with minimal manual intervention, offering advantages such as high automation and high assembly efficiency.

[0007] Preferably, the rotor and cam assembly workstation includes a rotor storage platform, a bearing assembly platform, a bearing supply device, a bearing pressing device, a cam box placement platform, a cam box heating platform, and a transfer robot.

[0008] The rotor storage platform is evenly provided with a number of rotor storage holes for inserting and fixing the ends of the rotors to be assembled.

[0009] The bearing assembly platform is provided with a rotor support seat, and the upper end of the rotor support seat is provided with a rotor support opening to support and limit the rotor placed flat therein, so as to prevent the rotor from moving during the bearing assembly process.

[0010] The bearing supply device is provided with two bearing supply ports for supplying bearings to both ends of the rotor on the rotor support.

[0011] The bearing pressing device has two sets, which are respectively located on both sides of the rotor support seat, and are used to press the bearing sleeved at the end of the rotor inward.

[0012] The cam box placement platform is evenly provided with several cam box storage slots for the end of the cam box to be assembled to be snapped in and fixed.

[0013] The cam box heating platform is equipped with a cam box heating device to heat the sleeve structure inside the cam box, thereby increasing the inner diameter of the sleeve structure.

[0014] The cam box heating platform is also equipped with a cam box pressing device to press and fix the rotor to the sleeve structure in the cam box.

[0015] The transfer robot is used to move bearings, rotors, and cam boxes.

[0016] With the above technical solution, before use, the rotors to be assembled are inserted and fixed one by one on the rotor storage platform through the rotor storage holes, the bearings to be assembled are placed in the bearing supply device, and the cam boxes to be assembled are snapped and fixed on the cam box placement platform through the cam box storage slot.

[0017] The process involves several steps: First, a robotic arm places the rotor to be assembled on the rotor storage platform into the support opening of the rotor support seat. The support opening abuts against the outer peripheral wall of the rotor, providing support and positioning. Second, a bearing supply device transports two bearings to both ends of the rotor, ensuring they are coaxial with the rotor. Third, a bearing pressing device presses the two bearings, securing them to the ends of the rotor. Fourth, a robotic arm places the cam box to be assembled on the cam box storage platform into the cam box heating platform. Fifth, a cam box heating device heats the inner sleeve structure of the cam box, increasing its inner diameter. Sixth, a robotic arm places the rotor, with bearings fixed at both ends, into the inner sleeve structure of the cam box. Seventh, a cam box pressing device presses the rotor and the inner sleeve structure of the cam box into place. Eighth, a robotic arm removes the assembled cam box from the cam box heating platform.

[0018] The above process only requires workers to manually stack the rotor and cam box and put the bearing into the bearing supply device. All other actions can be completed automatically, which has the advantages of high automation and high production efficiency.

[0019] Preferably, the bearing supply device includes two sets of bearing supply units arranged side by side on the upper end of the bearing assembly platform;

[0020] The bearing supply unit includes a bearing feeding box, a bearing jacking mechanism, and a bearing transport mechanism. A guide ramp is provided at the lower inner end of the bearing feeding box to guide the bearings inside the box to move obliquely downwards. The bearing jacking mechanism is located at the lower edge of the guide ramp to jack the bearings inside the bearing feeding box upwards. A jacking chamber is formed between the upper end of the bearing jacking mechanism and the inner wall of the bearing feeding box for inserting vertically positioned bearings. The feed end of the bearing transport mechanism penetrates the bearing feeding box and communicates with the jacking chamber. The discharge end of the bearing transport mechanism extends towards the rotor support.

[0021] The above technical solution, which supplies bearings to both ends of the rotor simultaneously through two bearing supply units, has the advantages of less time consumption and higher efficiency.

[0022] Because the guide ramp is set at an angle downwards, the bearings in the bearing supply box will move downwards continuously under the guidance of the guide ramp.

[0023] In use, the bearing in the bearing supply box is lifted upward by the bearing jacking mechanism. The bearing in the vertical position will be directly lifted by the bearing jacking mechanism because it is stuck in the jacking chamber. The bearing in the above state will flip and fall back into the bearing supply box. When the bearing in the jacking chamber is lifted by the bearing jacking mechanism to be directly opposite the bearing transport mechanism, the bearing transport mechanism will transport the bearing in the jacking chamber to the side of the rotor support.

[0024] Preferably, the lower end of the bearing feed box is provided with a jacking through hole in the vertical direction, and the upper end of the jacking through hole is engaged with the lower end of the guide slope.

[0025] The bearing jacking mechanism includes a bearing jacking plate and a bearing jacking cylinder. The bearing jacking plate is slidably disposed in the jacking through hole. The upper end of the bearing jacking plate is provided with a supporting inclined surface to cooperate with the inner wall of the bearing feed box to form a jacking chamber. The output end of the bearing jacking cylinder is connected to the bearing jacking plate to drive the bearing jacking plate to slide up and down in the jacking through hole.

[0026] With the above technical solution, when in use, the bearing jacking plate is first driven to move down by the bearing jacking cylinder until the upper end of the support slope is engaged with the lower end of the guide slope. At this time, the bearing in the bearing supply box will move along the guide slope to the jacking chamber side. Then, the bearing jacking plate is driven to move up by the bearing jacking cylinder to lift the bearing stuck in the jacking chamber upward.

[0027] Preferably, the bearing assembly platform is provided with a feeding box base, the bearing feeding box is located at the upper end of the feeding box base, and positioning grooves are provided on both sides of the feeding box base. The positioning grooves are connected to the top moving through hole on the same side, and the lower end of the bearing top moving plate is slidably disposed in the positioning groove on the same side.

[0028] An extension seat is provided on the lower side wall of the bearing jacking plate, and the cylinder body of the bearing jacking cylinder is fixedly installed on the outer wall of the bearing feed box. The output end of the bearing jacking cylinder is connected to the extension seat.

[0029] Through the above technical solution, the positioning groove can be used to limit the sliding of the bearing jacking plate, making it less prone to displacement during sliding. Furthermore, the positioning groove is located on the side wall of the feed box base, allowing operators to visually monitor the movement of the bearing jacking plate. By adding a feed box base and installing the bearing jacking cylinder to the side wall of the bearing feed box, the height of the bearing feed box can be reduced, making the installation of the bearing supply device less restrictive.

[0030] Preferably, the bearing transport mechanism includes a bearing transport track, a bearing transport mounting base, a bearing transport slide plate, and a bearing transport cylinder;

[0031] The feed end of the bearing transport track passes through the bearing feed box and is connected to the jacking chamber. The discharge end of the bearing transport track extends downward at an angle. The bearing transport fixing seat is located directly below the discharge end of the bearing transport track. The bearing transport slide plate is slidably disposed on the upper end of the bearing transport fixing seat. The upper end of the bearing transport slide plate has a bearing transfer hole for receiving the bearing falling from the discharge end of the bearing transport track. The output end of the bearing transport cylinder is connected to the bearing transport slide plate for transporting the bearing to the bearing extrusion device via the bearing transport slide plate.

[0032] With the above technical solution, when the bearing jacking mechanism transports the vertically positioned bearing to a position directly opposite the feed end of the bearing transport track, the bearing in the jacking chamber will roll into the bearing transport track and roll downwards along it. Simultaneously, the bearing transport cylinder directly drives the bearing transport slide plate away from the bearing extrusion device until the bearing transfer hole connects with the discharge end of the bearing transport track. At this point, a bearing at the discharge end of the bearing transport track will fall into the bearing transfer hole. Then, the bearing transport cylinder directly drives the bearing transport slide plate closer to the bearing extrusion device to transport the bearing towards it.

[0033] Preferably, the rotor support is slidably connected to the bearing assembly platform via a slide rail, and the bearing assembly platform is provided with a reset mechanism. The output end of the reset mechanism is connected to the rotor support to drive the rotor support to reset.

[0034] The two sets of bearing extrusion devices are a fixed extrusion device and a movable extrusion device, respectively;

[0035] The fixed extrusion device includes a bearing storage seat, the upper end of which is provided with a bearing placement groove for receiving bearings falling from one of the bearing transfer holes.

[0036] The movable extrusion device includes a bearing transfer seat and a bearing transfer cylinder. The upper end of the bearing transfer seat is provided with a bearing transfer groove to receive the bearing falling from another bearing transfer hole. The output end of the bearing transfer cylinder is connected to the bearing transfer seat to drive the bearing transfer seat to move closer to or away from the bearing storage seat.

[0037] With the above technical solution, when the two bearings enter the bearing placement slot and the bearing transfer slot respectively, the bearing transfer cylinder drives the bearing transfer seat closer to the bearing storage seat. During this process, the distance between the bearing transfer seat, the rotor support seat, and the bearing storage seat gradually decreases, thereby press-fitting and fixing the two bearings to both ends of the rotor. Then, the bearing transfer cylinder drives the bearing transfer seat away from the bearing storage seat, completing the resetting of the bearing transfer seat. Simultaneously, the resetting mechanism drives the rotor support seat away from the bearing storage seat, completing the resetting of the rotor support seat.

[0038] Preferably, the cam box heating platform is provided with a cam box heating station and a cam box pressing station, the cam box heating device is provided in the cam box heating station, and the cam box pressing device is provided in the cam box pressing station;

[0039] The cam box heating station is provided with a heating through hole running from top to bottom;

[0040] The cam box heating device includes a lifting mechanism and an induction heater disposed on the lifting mechanism. The lifting mechanism is used to drive the induction heater to move upward, so that the induction heating wire of the induction heater passes through the heating through hole and extends into the sleeve structure of the cam box.

[0041] With the above technical solution, when the cam box is placed in the cam box heating station by the transfer robot, and the sleeve structure inside the cam box is coaxial with the heating through hole, the induction heater is driven to move upward by the lifting mechanism, so that the induction heating wire of the induction heater passes through the heating through hole and extends into the sleeve structure of the cam box, so as to induction heat the sleeve structure inside the cam box, thereby increasing the inner diameter of the sleeve structure.

[0042] Preferably, the cam box pressing station is provided with a pressing through hole from top to bottom for one end of the rotor to pass through;

[0043] The cam box extrusion device includes an extrusion manipulator and an extrusion gripper cylinder mounted on the extrusion manipulator. The extrusion manipulator can not only drive the extrusion gripper cylinder to move laterally between the cam box heating station and the cam box pressing station, but also drive the extrusion gripper cylinder to move vertically up and down between the cam box heating station and the cam box pressing station. A clamping chamber for the cam box to be placed is formed between each gripper of the extrusion gripper cylinder.

[0044] The above technical solution involves five steps: First, a transfer robot inserts a rotor with bearings at both ends into the extrusion through-hole. Second, the extrusion robot controls the extrusion gripper cylinder to move towards the cam box heating station, allowing the cam box at the heating station to enter the clamping chamber. Third, the extrusion gripper cylinder clamps and secures the cam box. Fourth, the extrusion robot controls the extrusion gripper cylinder to move towards the cam box pressing station, ensuring that the sleeve structure inside the cam box is coaxial with the rotor. Fifth, the extrusion robot controls the extrusion gripper cylinder to move downwards, pressing and securing the cam box to the rotor.

[0045] Compared to the rotor, the cam box has more flat surfaces. Therefore, during the process of pressing and fixing the cam box and the rotor by controlling the downward movement of the cam box through the cam box pressing device, the relative movement between the cam box and the pressing jaw cylinder is less likely to occur, making the pressing process of the cam box and the rotor more efficient.

[0046] Preferably, the cam box fan blade installation workstation includes a frame, and the frame is provided with a head feeding station, a fan blade installation station, a snap ring pressing station, and a head flipping unloading station;

[0047] The frame is equipped with an indexing turntable, and each workstation is equipped with a head clamping device to clamp and fix the air compressor head to be assembled. The frame is equipped with a rotary power device, which is connected to the indexing turntable to drive the indexing turntable to rotate circumferentially at a specific angle, so that the air compressor head in the head clamping device can move between the workstations.

[0048] The compressor head loading station is equipped with a compressor head loading robot, which is used to clamp the compressor head to be assembled and put it into the compressor head clamping device opposite to the compressor head loading station.

[0049] A fan blade installation robot is provided at the fan blade installation station. The fan blade installation robot is used to clamp and fix the fan blades to be assembled and install them into the air compressor head.

[0050] A snap ring pressing device is provided at the snap ring pressing station. The snap ring pressing device is used to insert the snap ring into the air compressor head, thereby limiting the fan blades in the air compressor head.

[0051] The compressor head flipping and unloading station is equipped with a compressor head flipping and unloading robot. When the air compressor head with one end completed moves to the compressor head flipping and unloading station, the compressor head flipping and unloading robot can flip the air compressor head 180 degrees along the vertical plane; when the assembled air compressor head moves to the compressor head flipping and unloading station, the compressor head flipping and unloading robot will remove the assembled air compressor head.

[0052] The above technical solution involves the following steps when assembling the air compressor head and fan blades: First, a manipulator picks up the air compressor head to be assembled and places it into the head clamping device at the head loading station. The head clamping device then clamps and secures the air compressor head. Second, a rotary power device drives the indexing turntable to rotate circumferentially by a specific angle, moving the head clamping device holding the air compressor head to the fan blade installation station. Third, a fan blade installation manipulator installs the fan blades into the air compressor head. Fourth, the process continues... The rotary power unit drives the indexing turntable to rotate circumferentially by a specific angle, causing the air compressor head containing the fan blades, along with the head clamping device, to move to the snap ring pressing station. The fifth step involves using the snap ring pressing device to insert the snap ring into the air compressor head, locking and limiting the fan blades to the air compressor head. The sixth step involves the rotary power unit driving the indexing turntable to rotate circumferentially by a specific angle, causing the air compressor head, with one end assembled, along with the head clamping device, to move to the head tilting and unloading station. The seventh step involves the head tilting and unloading robot clamping the air compressor head and... The process involves several steps: First, the compressor head is rotated 180 degrees vertically. Second, the indexing turntable is rotated circumferentially by a rotary power device to move the assembled air compressor head, along with the head clamping device, to the compressor head loading station. Third, the indexing turntable is rotated circumferentially by a rotary power device to move the assembled air compressor head, along with the head clamping device, to the fan blade installation station. Fourth, the fan blade installation robot inserts the fan blades into the air compressor head. Fifth, the indexing turntable is rotated circumferentially by a rotary power device to move the assembled air compressor head, along with the fan blade clamping device, to the fan blade installation station. The process involves several steps: First, at a fixed angle, the air compressor head, containing the fan blades, is moved by the head clamping device to the circumferential clamping station. Second, the circumferential clamping device inserts the circumferential clamp into the air compressor head to lock and limit the fan blades to the compressor head. Third, a rotary power unit drives the indexing turntable to rotate circumferentially by a specific angle, moving the air compressor head, with one end assembled, by the head clamping device to the head tilting and unloading station. Fourth, a head tilting and unloading robot removes the air compressor head, with both ends assembled, from the head clamping device. In summary, this workstation reduces manual intervention during the assembly of the air compressor head and fan blades, resulting in high automation and high productivity.

[0080] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0081] Example 1: An air compressor assembly production line, such as Figures 1 to 22As shown, it includes a material conveying track 1 and several material support plates 2 arranged sequentially on the material conveying track 1. The material conveying track 1 is used to drive the material support plates 2 to move along the length direction of the material conveying track 1.

[0082] Along the moving direction of the material carrying plate 2, the side of the material conveying track 1 is sequentially equipped with a rotor and cam box assembly workstation 175, a cam box top cover installation workstation 176, a cam box fan blade installation workstation 177, and a fan blade mesh cover installation workstation 178. The rotor and cam box assembly workstation 175 can first install bearings at both ends of the rotor, then press the rotor into the inside of the cam box, and finally place the cam box on top of the material carrying plate 2. The cam box top cover installation workstation 176 is used to press and fix the top cover to the cam box placed on top of the material carrying plate 2 with bolts. The cam box fan blade installation workstation 177 is used to install fan blades at both ends of the cam box and lock the fan blades to the ends of the rotor with snap rings. The fan blade mesh cover installation workstation 178 is used to snap mesh covers on both ends of the cam box.

[0083] The rotor and cam box assembly workstation 175 includes a rotor storage platform 3, a bearing assembly platform 4, a bearing supply device 5, a bearing pressing device 16, a cam box placement platform 21, a cam box heating platform 22, and a transfer robot 23.

[0084] The rotor storage platform 3 is evenly provided with a number of rotor storage holes 24 for inserting and fixing the end of the rotor to be assembled. After the rotor is inserted into the rotor storage hole 24, the rotor will be in an upright state, making it more convenient to take it out.

[0085] The bearing assembly platform 4 is provided with a rotor support seat 25. The upper end of the rotor support seat 25 is provided with a rotor support opening 26. The shape of the rotor support opening 26 is adapted to the shape of the rotor to support and limit the rotor placed flat therein, so as to prevent the rotor from moving during the bearing assembly process.

[0086] The bearing supply device 5 is equipped with two bearing supply ports for supplying bearings to both ends of the rotor on the rotor support 25. The bearing supply device 5 includes two sets of bearing supply units arranged side-by-side on the upper end of the bearing assembly platform 4. Each bearing supply unit includes a bearing feed box 6, a bearing jacking mechanism 7, and a bearing transport mechanism 10.

[0100] The cam box fan blade installation workstation 177 includes a frame 73, on which are provided a head feeding station 74, a fan blade installation station 75, a snap ring pressing station 76, and a head flipping unloading station 77.

[0101] The frame 73 is equipped with an indexing turntable 78, and each station has a head clamping device 79 for clamping and fixing the air compressor head to be assembled. The frame 73 is equipped with a rotary power unit 92, which is connected to the indexing turntable 78 and drives the indexing turntable 78 to rotate circumferentially at a specific angle, so that the air compressor head in the head clamping device 79 can move between the stations.

[0102] The compressor head clamping device 79 includes a compressor head clamping base plate 80 fixedly mounted on an indexing turntable 78, two compressor head clamping units 81 slidably mounted on the compressor head clamping base plate 80, and a compressor head clamping drive member 84 for driving the two compressor head clamping units 81 to move closer or further apart from each other. The compressor head clamping unit 81 includes a compressor head clamping slide plate 82 slidably mounted on the compressor head clamping base plate 80 and a compressor head clamping head 83 fixedly mounted on the compressor head clamping slide plate 82. Limiting openings 151 are provided at opposite positions of the two compressor head clamping heads 83, and the shape of the limiting openings 151 is adapted to the compressor head of the air compressor.

[0103] When the air compressor head is placed between the two clamping heads 83, the clamping drive 84 only needs to control the two clamping slides 82 to move closer together, so that the limiting openings 151 on both clamping heads 83 abut against the air compressor head. When it is necessary to remove the air compressor head, the clamping drive 84 only needs to control the two clamping slides 82 to move away from each other until both clamping heads 83 are separated from the air compressor head. The limiting openings 151 on the clamping heads 83 can effectively increase the contact area between the clamping heads 83 and the air compressor head, so as to clamp the air compressor head more stably and effectively.

[0105] In use, the extension and retraction of the output end of the head clamping cylinder 86 can drive one of its head clamping slide plates 82 to move via the head clamping drive block 87. Simultaneously, the moving head clamping slide plate 82 will drive the transmission rod 90 to rotate around the connecting column 89 via the corresponding response rod 91. The transmission rod 90 will then drive the other head clamping slide plate 82 to move via another response rod 91. The head clamping drive unit 84 configured as described above only requires a single drive source to control the synchronous and reverse movement of the two head clamping slide plates 82, offering advantages such as low energy consumption and high synchronization.

The two feed response links 107 are respectively fixedly connected to the two feed clamps 101 on the machine head.

[0111] In use, the extension and retraction of the output end of the active feeding cylinder drives one of the feeding grippers 101 on the machine head to move. At the same time, the feeding gripper 101 drives the feeding transmission link 106 to rotate around the feeding mounting column 105 via the corresponding feeding response link 107. The feeding transmission link 106 then drives the corresponding feeding gripper 101 on the machine head to move via the other feeding response link 107. The machine head feeding clamping mechanism 99 configured as described above only requires a single drive source to control the synchronous and reverse movement of the two feeding grippers 101 on the machine head, which has the advantages of low energy consumption and high synchronization.

[0112] A fan blade installation robot 108 is installed at fan blade installation station 75. The fan blade installation robot 108 is used to clamp and fix the fan blades to be assembled and install them into the air compressor head.

[0114] In use, the first step is to clamp and fix the fan blades using the pneumatic gripper 116. The second step is to drive the fan blades horizontally using the fan blade loading and lateral movement mechanism 111, while simultaneously driving them vertically using the fan blade loading and lifting mechanism 113, until the fan blades are directly above the air compressor head. The third step is to drive the fan blades downwards using the fan blade loading and lifting mechanism 113 to load them into the air compressor head. The fourth step is to drive the pneumatic gripper 116 upwards using the fan blade loading and lifting mechanism 113, allowing the air... The moving gripper 116 separates from the air compressor head. In the fifth step, the pressing seat 117 is driven to move horizontally by the fan blade mounting lateral movement mechanism 115, so that the pressing seat 117 moves to directly above the air compressor head. In the sixth step, the pressing seat 117 is driven to move downward by the fan blade feeding lifting mechanism 113 to press and fix the fan blade to the air compressor head. In the seventh step, the pneumatic gripper 116 is reset by the fan blade feeding lifting mechanism 113, the fan blade feeding lateral movement mechanism 111, and the fan blade mounting lateral movement mechanism 115.

[0115] A snap ring pressing device 118 is provided at snap ring pressing station 76. The snap ring pressing device 118 is used to insert the snap ring into the air compressor head, thereby limiting the fan blades in the air compressor head.

[0117] The snap ring dispensing mechanism 119 includes a dispensing base 120, a snap ring pre-installation bracket 121, a snap ring push plate 122, and a dispensing cylinder 123. The dispensing base 120 has a dispensing opening 152 near the snap ring pressing mechanism 124. The dispensing opening 152 extends upward through the dispensing base 120. The lower end of the snap ring pre-installation bracket 121 extends into the dispensing opening 152. The snap ring to be assembled is set on the outside of the snap ring pre-installation bracket 121. The snap ring push plate 122 is slidably set in the dispensing opening 152. The upper end of the snap ring push plate 122 abuts against the lower end of the snap ring pre-installation bracket 121. The snap ring push plate 122 has a transfer opening 153 near the snap ring pressing mechanism 124 for inserting a single snap ring. The output end of the dispensing cylinder 123 passes through the dispensing base 120 and is connected to the snap ring push plate 122.

[0118] The snap ring pressing mechanism 124 includes a snap ring adapter pressing head 125, a snap ring pressing truss 126, a snap ring lifting slide 127 slidably mounted on the snap ring pressing truss 126 in the vertical direction, a snap ring lifting assembly 128 disposed between the snap ring pressing truss 126 and the snap ring lifting slide 127, a snap ring transverse sliding plate 129 slidably mounted on the snap ring lifting slide 127 in the horizontal direction, a snap ring transverse sliding assembly 130 disposed between the snap ring lifting slide 127 and the snap ring transverse sliding plate 129, a snap ring picking head 131 fixedly mounted at the lower end of the snap ring transverse sliding plate 129, a snap ring ejection sleeve 132 slidably mounted on the outside of the snap ring picking head 131 in the vertical direction, and a snap ring ejection assembly 133 disposed between the snap ring transverse sliding plate 129 and the snap ring ejection sleeve 132. The upper end of the snap ring adapter pressing head 125 is provided with an adapter groove 154 for the snap ring picking head 131 to pass through.

[0119] In use, the first step involves the dispensing cylinder 123 driving the snap ring push plate 122 to move inward toward the dispensing opening 152, so that the transfer opening 153 is aligned with the snap ring pre-mounted bracket 121. At this time, a snap ring located at the lower end of the snap ring pre-mounted bracket 121 will fall into the transfer opening 153. The second step involves the dispensing cylinder 123 driving the snap ring push plate 122 to move outward toward the dispensing opening 152, so that the transfer opening 153 is aligned with the snap ring adapter head 125. During this process, because the snap ring push plate 122 abuts against the lower end of the snap ring pre-mounted bracket 121, the snap ring push plate 122 can prevent the snap ring fitted on the snap ring pre-mounted bracket 121 from falling. The third step involves the snap ring lateral movement assembly 130 driving the snap ring picking head 131 and the snap ring ejection sleeve 132 to move to the snap ring... Above the spring adapter head 125, in the fourth step, the spring clipping head 131 and the spring clip ejector sleeve 132 are driven to move downwards by the spring clip lifting assembly 128. When the spring clipping head 131 extends into the adapter groove 154, the spring clip on the spring clip push plate 122 will be transferred to the spring clipping head 131. In the fifth step, the spring clip lifting assembly 128 and the spring clip lateral movement assembly 130 are driven to move the spring clipping head 131 and the spring clip ejector sleeve 132 to the inside of the air compressor head, so that the spring clipping head 131 abuts against the rotating shaft in the air compressor head used to fit the fan blade. In the sixth step, the spring clip ejector sleeve 132 is driven to move downwards by the spring clip ejector assembly 133 to install the spring clip onto the rotating shaft in the air compressor head used to fit the fan blade, thereby limiting and fixing the fan blade.

The two head-tilting and unloading response links 150 are respectively fixedly connected to the two head-tilting and unloading grippers 144.

[0126] In use, the extension and retraction of the output end of the active drive cylinder for tilting and unloading moves one of the machine head tilting and unloading grippers 144. Simultaneously, this machine head tilting and unloading gripper 144 drives the corresponding tilting and unloading response link 150 to rotate the tilting and unloading transmission link 149 around the tilting and unloading mounting column 148. The tilting and unloading transmission link 149 then drives the corresponding machine head tilting and unloading gripper 144 to move via the other tilting and unloading response link 150. The machine head tilting and unloading clamping mechanism 142 configured as described above only requires a single drive source to control the synchronous and reverse movement of the two machine head tilting and unloading grippers 144, offering advantages such as low energy consumption and high synchronization.

[0127] Example 2: The difference between Example 2 and Example 1 is that, as Figures 23 to 26 As shown, both bearing extrusion devices 16 are equipped with bearing inner ring heating devices 59, and the bearing inner ring heating devices 59 are located on the side of the bearing extrusion device 16 away from the rotor support 25. The heating end of the bearing inner ring heating device 59 can extend into the inner ring of the bearing to heat the inner ring of the bearing, thereby increasing the inner diameter of the bearing inner ring, which makes it easier to fit and fix the rotor and the bearing together.

[0128] The bearing inner ring heating device 59 includes a receiving sleeve 60 fixedly mounted on the side wall of the bearing extrusion device 16. The inner hole of the receiving sleeve 60 is coaxially connected to the inner hole of the bearing extrusion device 16 for the rotor end to pass through. A sleeve connection hole 61 is provided at the upper end of the outer peripheral wall of the receiving sleeve 60. The sleeve connection hole 61 extends axially along the receiving sleeve 60 and is connected to the inner hole of the receiving sleeve 60. The receiving sleeve 60 is made of high-temperature resistant material. A heating core rod 62 is provided inside the receiving sleeve 60, and the heating core rod 62 can slide back and forth along the axial direction of the receiving sleeve 60. An electric wire 63 is provided at the upper end of the outer peripheral wall of the heating core rod 62. The electric wire 63 passes through the sleeve connection hole 61 for connection to an external power source. A heat insulation block 64 is fixedly installed at the end of the heating core rod 62 located inside the receiving sleeve 60. The heat insulation block 64 can slide back and forth along the circumference of the receiving sleeve 60. A return spring 65 is provided inside the receiving sleeve 60. One end of the return spring 65 abuts against the inner wall of the end of the receiving sleeve 60, and the other end abuts against the heat insulation block 64. The return spring 65 applies a spring force to the heating core rod 62 through the heat insulation block 64, causing the end of the heating core rod 62 to protrude out of the receiving sleeve 60 and extend into the inner ring of the bearing for heating the inner ring of the bearing.

[0129] A positioning annular groove 66 is provided on the outer peripheral wall of the end of the heating core rod 62. The positioning annular groove 66 extends circumferentially along the heating core rod 62 and is connected end to end. Both the bearing storage seat and the bearing transfer seat 19 are provided with trigger response mechanisms 67.

[0130] The lower end of the inner wall of the bearing placement channel 53 and the bearing transfer channel 54 is provided with a trigger receiving groove 68, and the side of the inner wall of the bearing placement channel 53 and the bearing transfer channel 54 is provided with a response receiving groove 69.

The lower end of the response plate 71 is fixedly connected to the trigger plate 70. The support spring 72 is located at the lower end of the trigger plate 70. The upper end of the support spring 72 is connected to the trigger plate 70, and the lower end of the support spring 72 is connected to the lower end of the inner wall of the trigger receiving groove 68. The support spring 72 drives the upper end of the trigger plate 70 to protrude out of the trigger receiving groove 68 through elastic force, and the upper end of the response plate 71 extends into the inner hole of the bearing storage seat and the bearing transfer seat 19.

[0131] When the bearing falls into the bearing placement slot 53 and the bearing transfer slot 54, the bearing will press against the trigger plate 70 of the trigger response mechanism 67 in the bearing placement slot 53 and the bearing transfer slot 54, causing the trigger plate 70 to retract into the bearing storage seat and the bearing transfer seat 19. At the same time, the trigger plate 70 presses down on the support spring 72 and drives the response plate 71 to move down, causing the upper end of the response plate 71 to be misaligned with the inner hole of the bearing storage seat and the bearing transfer seat 19. At this time, the return spring 65 drives the end of the heating core rod 62 to extend into the inner ring of the bearing through its elastic force to heat the inner ring of the bearing.

[0132] When the movable extrusion device 18 and the fixed extrusion device 17 are used together to press and fix the rotor and the bearing, the two ends of the rotor push the two heating core rods 62 into the corresponding storage sleeves 60 respectively.

[0133] After the rotor and bearing are press-fitted, the movable pressing device 18 and the rotor support 25 will move away from the fixed pressing device 17, and the moving speed of the movable pressing device 18 will be greater than the moving speed of the fixed pressing device 17. When the end of the rotor is about to leave the bearing placement slot 53 and the bearing transfer slot 54, the support spring 72 will drive the trigger plate 70 to protrude upward from the inner wall of the bearing placement slot 53 and the bearing transfer slot 54 through its elastic force. At the same time, the trigger plate 70 will drive the response plate 71 to move upward, so that the response plate 71 extends into the positioning ring groove 66, thereby restricting the end of the heating core rod 62 from extending into the bearing placement slot 53 and the bearing transfer slot 54.

[0134] The press base 117 includes a press support 157, a spinning plate 158, and a spinning drive mechanism 159.

[0135] The press-fit support 157 is fixedly mounted on the lower end of the fan blade mounting slide 114. The upper end of the press-fit support 157 has an annular mounting chamber 162, and the outer ring of the mounting chamber 162 penetrates the outer peripheral wall of the press-fit support 157. The lower end of the press-fit support 157 is provided with a connecting rod 163, the lower end of which extends vertically downwards, and a spiral guide groove 164 is provided on the outer side of the connecting rod 163.

[0136] A spinning disc 158 has a spinning connection hole 165 extending through its center. The inner diameter of the spinning connection hole 165 is the same as the outer diameter of the connecting rod 163, and the spinning disc 158 is fitted onto the outside of the connecting rod 163 through the spinning connection hole 165. A hemispherical guide protrusion 166 is provided on the inner wall of the spinning connection hole 165, and the guide protrusion 166 is slidably disposed in the spiral guide groove 164. When the spinning disc 158 slides up and down along the axial direction of the connecting rod 163, the guide protrusion 166 and the spiral guide groove 164 cooperate to drive the spinning disc 158 to rotate circumferentially.

[0137] The lower end of the spinning disc 158 has an annular buffer groove 167. The longitudinal cross-sectional shape of the buffer groove 167 is T-shaped, and the central axis of the buffer groove 167 coincides with the central axis of the spinning connection hole 165. A movable pressure ring 168 is provided in the buffer groove 167. The shape of the movable pressure ring 168 is adapted to the shape of the buffer groove 167, and the movable pressure ring 168 can slide up and down along the axial direction of the buffer groove 167. A positioning groove 169 is provided axially on the inner wall of the buffer groove 167, and a positioning protrusion 170 is provided on the outer peripheral wall of the movable pressure ring 168. The positioning protrusion 170 extends into the positioning groove 169 to restrict the circumferential rotation of the movable pressure ring 168 in the buffer groove 167. The buffer ring groove 167 also includes a ring-shaped buffer airbag 171 filled with inert gas. The upper end of the buffer airbag 171 abuts against the inner wall of the upper end of the buffer ring groove 167, and the lower end of the buffer airbag 171 is provided with a smooth metal abutment piece 172, which abuts against the upper end of the movable pressure ring 168 to reduce the friction between the buffer airbag 171 and the movable pressure ring 168. The buffer airbag 171, through pressure, causes the lower end of the movable pressure ring 168 to protrude from the groove opening of the buffer ring groove 167 and maintain this state. The lower end of the movable pressure ring 168 is provided with a rubber pressure ring 173, which abuts against the fan blade to be pressed, thereby driving the fan blade to rotate circumferentially with the movable pressure ring 168.

[0138] A circular connecting groove 174 is coaxially formed on the outer peripheral wall of the spinning disc 158. The spinning drive mechanism 159 includes two spinning drive cylinders 160, which are symmetrically distributed around the connecting rod 163. The cylinder body of the spinning drive cylinder 160 is fixedly connected to the lower inner wall of the mounting chamber 162. The piston rod of the spinning drive cylinder 160 passes downward through the press-fit support 157 and extends to the side of the spinning disc 158. A connecting piece 161 is provided at the end of the piston rod of the spinning drive cylinder 160. The connecting piece 161 extends radially along the spinning disc 158, and the end of the connecting piece 161 extends into the connecting groove 174. When the piston rod of the spinning drive cylinder 160 extends or retracts, the spinning drive cylinder 160 drives the spinning disc 158 to move axially through the cooperation of the connecting piece 161 and the connecting groove 174.

[0139] To ensure that the drive shaft located inside the air compressor head can effectively drive the fan blades to rotate circumferentially when the air compressor head is running, a limiting plane is usually set on the outer peripheral wall of the drive shaft, and an abutting plane is set on the inner wall of the fan blade to fit properly with the limiting plane. Therefore, when the fan blade is placed directly on top of the drive shaft inside the air compressor head using the pneumatic gripper 116, the fan blade often cannot be fitted onto the outside of the drive shaft because the limiting plane is not aligned with the abutting plane.

[0140] When the above situation occurs, the first step is to drive the pressing seat 117 to move horizontally via the fan blade installation lateral movement mechanism 115, so that the pressing seat 117 moves above the air compressor head. The second step is to drive the pressing seat 117 downward via the fan blade loading lifting mechanism 113, so that the connecting rod 163 on the pressing seat 117 passes through the inner hole of the fan blade and abuts against the upper end of the drive shaft. At this time, the connecting rod 163 passing through the inner hole of the fan blade can be used to support and limit the fan blade, so that the fan blade is not easy to shake during subsequent installation. At the same time, the rubber located at the lower end of the spinning disc 158 The rubber pressure ring 173 will abut against the upper end of the fan blade to further support and limit the fan blade, making it less likely for the fan blade to wobble during subsequent installation. Furthermore, the rubber pressure ring 173 is made of soft rubber, which prevents the upper edge of the fan blade from being deformed by pressure. The third step involves controlling the piston rod of the spinning drive cylinder 160 to extend downwards. The piston rod of the spinning drive cylinder 160 will drive the spinning disc 158 to move axially downwards through the cooperation of the connecting piece 161 and the connecting ring groove 174. Simultaneously, the spinning disc 158 will... The fan blades rotate circumferentially along the lower edge, and the spinning disc 158 drives the fan blades to rotate circumferentially via the rubber pressure ring 173. When the limiting plane is not yet aligned with the contact plane, the fan blades and the drive shaft will maintain a relatively fixed axial position. Thus, during the downward movement of the spinning disc 158, the fan blades will squeeze the movable pressure ring 168 into the buffer groove via the rubber pressure ring 173. During this process, the buffer airbag 171 can deform into the movable pressure ring 168 to provide axial movement space, and the rubber pressure ring 173 can also deform into the movable pressure ring 168 to provide axial movement space. When the limiting plane rotates to... When facing the contact plane, the buffer airbag 171 will drive the movable pressure ring 168 and the rubber pressure ring 173 to move down through pressure, thereby fitting the fan blade onto the outside of the drive shaft. In the fourth step, the piston rod of the spinning drive cylinder 160 is controlled to retract upward. The piston rod of the spinning drive cylinder 160 will drive the spinning disc 158 to move upward along the axial direction through the cooperation of the connecting piece 161 and the connecting ring groove 174, thus completing the reset of the spinning disc 158. In the fifth step, the pressing seat 117 is driven to move through the fan blade mounting transverse mechanism 115 and the fan blade loading lifting mechanism 113, thus completing the reset of the pressing seat 117.

[0141] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
