[0002] At present, when the bearing, rotor and cam box of the air compressor are combined and assembled, the first step is to clamp and fix the rotor by a clamping device, the second step is to sleeve the bearing to both ends of the rotor, the third step is to extrude the bearing at both ends of the rotor by an extruding device, so that the bearing is moved and fixed at the specified position of the rotor, the fourth step is to heat the sleeve structure in the cam box for installing the rotor by a heating device, so that the inner hole diameter of the sleeve structure is expanded, the fifth step is to put the end of the rotor into the sleeve structure, and the sixth step is to extrude the rotor by the extruding device, so that the rotor is embedded into the sleeve structure. However, in the above process, manual participation of workers is required, and there is a defect of low production efficiency. SUMMARY

[0003] Therefore, the present application aims to provide a bearing, rotor and cam box combined assembly work station for an air compressor, which has the advantage of high production efficiency.

[0004] In order to solve the above technical problems, the technical scheme of the present application is as follows: a bearing, rotor and cam box combined assembly work station for an air compressor, comprising a rotor storage platform, a bearing sleeving platform, a bearing supply device, a bearing extruding device, a cam box placing platform, a cam box heating platform and a transfer manipulator.

[0005] The rotor storage platform is uniformly provided with a plurality of rotor storage holes for inserting and fixing the end of the rotor to be assembled.

[0006] The bearing sleeving platform is provided with a rotor support seat, and the upper end of the rotor support seat is provided with a rotor support opening for supporting and limiting the rotor placed therein, so as to avoid movement of the rotor during the bearing sleeving process.

[0007] The bearing supply device is provided with two bearing supply ports for respectively supplying bearings to both ends of the rotor on the rotor support seat.

[0008] The bearing extruding device has two groups and is arranged on both sides of the rotor support seat for extruding the bearings sleeved on the end of the rotor inwardly.

[0009] The cam box placing platform is uniformly provided with a plurality of cam box storage grooves for clamping and fixing the end of the cam box to be assembled.

[0010] The cam box heating platform is provided with a cam box heating device for heating the sleeve structure on the inner side of the cam box, so that the inner diameter of the sleeve structure is increased.

[0011] The cam box extrusion device is arranged on the cam box heating platform, and is used for press-fitting and fixing the rotor and the sleeve structure in the cam box.

[0012] The transfer manipulator is used for carrying the bearing, the rotor and the cam box.

[0013] Through the above technical scheme, before use, the rotor to be assembled is inserted and fixed on the rotor storage platform through the rotor storage hole one by one, the bearing to be assembled is placed into the bearing supply device, and the cam box to be assembled is clamped and fixed on the cam box placing platform through the cam box storage slot.

[0014] Firstly, the transfer manipulator is used for placing 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, and the rotor is supported and limited. Secondly, the bearing supply device is used for transporting the two bearings to the two ends of the rotor respectively, so that the bearings are coaxial with the rotor. Thirdly, the two bearing extrusion devices are used for extruding the two bearings respectively, so that the bearings are fixedly sleeved on the ends of the rotor. Fourthly, the transfer manipulator is used for placing the cam box to be assembled on the cam box storage platform into the cam box heating platform. Fifthly, the cam box heating device is used for heating the sleeve structure inside the cam box, so that the inner diameter of the sleeve structure is increased. Sixthly, the transfer manipulator is used for placing the rotor with the bearings fixedly sleeved on the two ends into the sleeve structure inside the cam box. Seventhly, the cam box extrusion device is used for press-fitting and fixing the rotor and the sleeve structure inside the cam box. Eighthly, the transfer manipulator is used for carrying away the assembled cam box from the cam box heating platform.

[0015] In the above process, only the workers manually stack the rotor and the cam box, and place the bearings into the bearing supply device, and the rest of the actions can be automatically completed, so that the automation degree is high, and the production efficiency is high.

[0016] Preferably, the bearing supply device comprises two groups of bearing supply units arranged side by side on the upper end of the bearing sleeving platform.

[0017] The bearing supply unit comprises a bearing supply box, a bearing jacking mechanism and a bearing conveying mechanism. The inner lower end of the bearing supply box is provided with a guide slope, which is used for guiding the bearing inside the bearing supply box to move obliquely downward. The bearing jacking mechanism is arranged at the lower end edge of the guide slope, and is used for jacking up the bearing inside the bearing supply box upward. The upper end of the bearing jacking mechanism and the inner wall of the bearing supply box form a jacking chamber, which is used for clamping the bearing in an upright state. The feeding end of the bearing conveying mechanism penetrates through the bearing supply box, and is used for being in communication with the jacking chamber. The discharging end of the bearing conveying mechanism extends to one side of the rotor support seat.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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;

[0028] 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.

[0029] 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.

[0030] 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.

[0031] The two sets of bearing extrusion devices are a fixed extrusion device and a movable extrusion device, respectively;

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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;

[0036] The cam box heating station is provided with a heating through hole running from top to bottom;

[0037] 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.

[0038] 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.

[0039] Preferably, the lifting mechanism includes a vertically arranged lifting cylinder, a lifting plate disposed at the output end of the lifting cylinder, and an induction heater disposed at the upper end of the lifting plate.

[0040] Through the above technical solution, the piston rod of the lifting cylinder can drive the lifting plate to move upward during the extension process, and can drive the lifting plate to move downward when the piston rod of the lifting cylinder retracts.

[0041] 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;

[0042] The cam box extrusion device includes an extrusion manipulator and a gripper cylinder mounted on the extrusion manipulator. The extrusion manipulator can not only drive the gripper cylinder to move laterally between the cam box heating station and the cam box pressing station, but also drive the 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 gripper cylinder.

[0043] The above technical solution involves five steps: First, a transfer robot inserts a rotor with bearings at both ends into the extrusion hole. Second, the extrusion robot controls the 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 gripper cylinder clamps and secures the cam box. Fourth, the extrusion robot controls the gripper cylinder to move towards the cam box pressing station, ensuring the inner sleeve structure of the cam box is coaxial with the rotor. Fifth, the extrusion robot controls the gripper cylinder to move downwards, pressing and securing the cam box to the rotor.

[0044] Compared to the rotor, the cam box has more flat surfaces. Therefore, during the process of pressing the cam box and the rotor together by controlling the downward movement of the cam box through the cam box pressing device, the relative movement between the cam box and the gripper cylinder is less likely to occur, making the pressing process between the cam box and the rotor more efficient.

[0045] Preferably, the extrusion manipulator includes a transport bracket, a horizontal sliding block slidably disposed on the transport bracket, a horizontal driving member disposed on the transport bracket for driving the horizontal sliding block, a vertical sliding table slidably disposed on the horizontal sliding block, a vertical driving member disposed on the horizontal sliding block for driving the vertical sliding table, and the gripper cylinder is disposed on the vertical sliding table.

[0046] Through the above technical solution, the transverse drive component can drive the transverse slide to move horizontally, thereby controlling the movement of the gripper cylinder between the cam box heating station and the cam box pressing station. The longitudinal drive component can drive the longitudinal slide to move up and down, thereby controlling the movement of the gripper cylinder up and down, completing the handling and pressing of the cam box.

A clamping chamber for inserting the cam box is formed between each gripper of the gripper cylinder 132.

[0073] In this embodiment, two sets of extrusion manipulators 131 are provided, so that when one extrusion manipulator 131 moves the cam box at the cam box heating station 23 to the cam box pressing station 24, the other extrusion manipulator 131 can move the cam box at the cam box pressing station 24 away.

[0074] The extrusion manipulator 131 includes a transport bracket 1311, a horizontal slide block 1312 slidably mounted on the transport bracket 1311, a horizontal drive component 1313 mounted on the transport bracket 1311 for driving the horizontal slide block 1312, a vertical slide table 1314 slidably mounted on the horizontal slide block 1312, and a vertical drive component 1315 mounted on the horizontal slide block 1312 for driving the vertical slide table 1314.

[0075] Example 2: Figure 8 , Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that both bearing extrusion devices 4 are equipped with bearing inner ring heating devices 27, and the bearing inner ring heating devices 27 are located on the side of the bearing extrusion device 4 away from the rotor support 9. The heating end of the bearing inner ring heating device 27 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 bearing together.

[0076] The bearing inner ring heating device 27 includes a receiving sleeve 271 fixedly mounted on the side wall of the bearing extrusion device 4.

A heat insulation block 275 is fixedly installed at the end of the heating core rod 273 located inside the receiving sleeve 271. The heat insulation block 275 can slide back and forth along the circumference of the receiving sleeve 271. A return spring 276 is provided inside the receiving sleeve 271. One end of the return spring 276 abuts against the inner wall of the end of the receiving sleeve 271, and the other end abuts against the heat insulation block 275. The return spring 276 applies a spring force to the heating core rod 273 through the heat insulation block 275, causing the end of the heating core rod 273 to protrude out of the receiving sleeve 271 and extend into the inner ring of the bearing for heating the inner ring of the bearing.

[0077] A positioning ring groove 28 is provided on the outer peripheral wall of the end of the heating core rod 273. The positioning ring groove 28 extends circumferentially along the heating core rod 273 and is connected end to end. Both the bearing storage seat and the bearing transfer seat 421 are provided with trigger response mechanisms 29.

[0078] The lower end of the inner wall of the bearing placement channel 21 and the bearing transfer channel 22 is provided with a trigger receiving groove 291, and the side of the inner wall of the bearing placement channel 21 and the bearing transfer channel 22 is provided with a response receiving groove 292. The upper end of the response receiving groove 292 is connected to the inner hole of the bearing storage seat and the bearing transfer seat 421, and the lower end of the response receiving groove 292 is connected to the trigger receiving groove 291. The trigger response mechanism 29 includes a trigger plate 293, a response plate 294, and a support spring 295. The trigger plate 293 is disposed in the trigger receiving groove 291 and can slide up and down in the trigger receiving groove 291. The response plate 294 is disposed in the response receiving groove 292 and can slide up and down in the response receiving groove 292. The lower end of the response plate 294 is fixedly connected to the trigger plate 293. The support spring 295 is located at the lower end of the trigger plate 293. The upper end of the support spring 295 is connected to the trigger plate 293, and the lower end of the support spring 295 is connected to the lower end of the inner wall of the trigger receiving groove 291. The support spring 295 drives the upper end of the trigger plate 293 to protrude out of the trigger receiving groove 291 through elastic force, and the upper end of the response plate 294 extends into the inner hole of the bearing storage seat and the bearing transfer seat 421.

[0079] When the bearing falls into the bearing placement slot 21 and the bearing transfer slot 22, the bearing will press against the trigger plate 293 of the trigger response mechanism 29 in the bearing placement slot 21 and the bearing transfer slot 22, causing the trigger plate 293 to retract into the bearing storage seat and the bearing transfer seat 421. At the same time, the trigger plate 293 presses down on the support spring 295 and drives the response plate 294 to move down, causing the upper end of the response plate 294 to be misaligned with the inner hole of the bearing storage seat and the bearing transfer seat 421. At this time, the return spring 276 drives the end of the heating core 273 to extend into the inner ring of the bearing through its elastic force, so as to heat the inner ring of the bearing.

[0080] When the movable extrusion device 42 and the fixed extrusion device 41 are used together to press and fix the rotor and the bearing, the two ends of the rotor push the two heating core rods 273 into the corresponding storage sleeves 271 respectively.

[0081] After the rotor and bearing are press-fitted, the movable pressing device 42 and the rotor support 9 will move away from the fixed pressing device 41, and the moving speed of the movable pressing device 42 will be greater than the moving speed of the fixed pressing device 41. When the end of the rotor is about to leave the bearing placement slot 21 and the bearing transfer slot 22, the support spring 295 will drive the trigger plate 293 to protrude upward from the inner wall of the bearing placement slot 21 and the bearing transfer slot 22 through its elastic force. At the same time, the trigger plate 293 will drive the response plate 294 to move upward, so that the response plate 294 extends into the positioning ring groove 28, thereby restricting the end of the heating core 273 from extending into the bearing placement slot 21 and the bearing transfer slot 22.

[0082] 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.
