Description

Technical Field

[0001] This invention relates to the field of advanced manufacturing and automation technology, and in particular to an assembly device for an air pump rotor. Background Technology

[0002] Car air pumps were initially used in high-end luxury sedans from brands like BMW, Mercedes-Benz, and Audi (BBA), becoming standard comfort features in million-yuan luxury cars. However, they didn't become mainstream technology in the early days because the manufacturing process of the entire shock absorption system, especially air springs, was immature, resulting in high unit prices and consequently, a lack of market for air pumps. In recent years, with the continuous expansion of the electric car market and advancements in technology, the production cost of air springs has decreased to less than one-tenth of its early cost. Air spring shock absorption systems have gradually become standard equipment in electric cars, and the air pump market is poised for explosive growth.

[0003] As the quality of new energy vehicles rapidly improves, consumers are demanding higher and higher performance from the overall vehicle. The main requirements for the chassis include: lightweight design, strength and safety, comfort, handling stability, and ground clearance. A high-performance air pump can improve the overall comfort and handling stability of a vehicle.

[0004] However, the manufacturing process of air pumps is novel, and there is no mature experience yet. The assembly of the air pump rotor is particularly important, as its quality affects the performance of the air pump motor. During rotor assembly, the rotor must be assembled with the eccentric shaft of the air pump. One end of the rotor is inserted into the insertion hole at the end of the eccentric shaft. Generally, a press-fit method is used to assemble the rotor. During press-fitting, the coaxiality of the rotor and the insertion hole must be ensured, and the eccentric shaft must be supported from the opposite direction of press-fitting. The conventional support structure is a support rod, but due to the high press-fitting pressure on the rotor, and the fact that the eccentric shaft itself cannot withstand too much force in the press-fitting direction, and the relatively small support capacity of conventional structures, it is easy to damage sensitive parts (such as sensors) in the press-fitting direction, and also prone to damage to the eccentric shaft and internal cylinder components due to support failure.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0023] like Figure 1-5As shown, an assembly device for an air pump rotor includes a pressing mechanism 1, a positioning mechanism 2, and a load-bearing locking mechanism 3. The positioning mechanism 2 is located above the worktable 4 and is used to position workpiece one. The pressing mechanism 1 is located above the positioning mechanism 2 and is used to press workpiece two so that workpiece two is assembled with the accessories on workpiece one. The load-bearing locking mechanism 3 is located on the worktable 4 and includes a support rod 31, a positioning shaft 32, a load-bearing locking block 33, and a locking cylinder 34. The support rod 31 can move in the opposite direction of pressing under the action of external force. The positioning shaft 32 is located at the top of the support rod 31 and can move with the support rod 31 to position the accessories on workpiece one. The support rod 31 is provided with an insertion hole 311 that is perpendicular to the pressing direction. In this embodiment, the pressing direction is vertical, and the direction perpendicular to the pressing direction is horizontal. The load-bearing locking block 33 is inserted into the insertion hole 311 and is slidably connected to the insertion hole 311. The stop cylinder 34 is located above the worktable 4, and its output end is connected to the load-bearing locking block 33. The top of the insertion hole 311 is provided with a roller 35 protruding from the top surface of the insertion hole. The roller 35 is embedded in the support rod 31 and can roll or not roll in the mounting hole of the support rod. The positioning shaft 32, the support rod 31, and the roller 35 are aligned, and the center lines of the three are on the same plane, so that the pressing force is concentrated, avoiding pressing deviation and improving the pressing quality. The load-bearing locking block 33 is provided with a locking part 331 that cooperates with the outer periphery of the roller 35. That is, the surface of the roller 35 cooperating with the locking part 331 is an arc surface, and the top of the locking part 331 is a slope. When the positioning shaft 32 moves the mounting part on the positioning workpiece in the opposite direction of pressing, the locking cylinder 34 drives the load-bearing locking block 33 to move so that the locking part 331 abuts against the outer periphery of the roller 35 to lock the support rod 31. In the unlocked state, the locking part 331 does not contact the roller 35.

[0024] This invention is mainly used for the automatic assembly of air pump rotors. The first part is the cylinder of the air pump, and the mounting part on the first part is an eccentric shaft located inside the cylinder. The second part is the rotor. During assembly, the rotor needs to be pressed onto the eccentric shaft inside the cylinder. Specifically, the lower end of the rotor shaft is connected to the mounting hole at the upper end of the eccentric shaft.

[0025] In the above structure, such as Figure 5 As shown, the upper end of the positioning shaft 32 is provided with a support part 321 and a positioning part 322. Under the action of external force, the support part 321 abuts against the lower end face of the assembly to support the assembly. The positioning part 322 is located above the support part 321. The positioning part 322 is inserted into the assembly to position the assembly. The positioning shaft achieves precise positioning of the eccentric shaft, so that the eccentric shaft and the rotor are assembled accurately.

[0026] Among them, such as Figure 4-5As shown, the load-bearing locking mechanism 3 also includes a load-bearing slide 36 and a lifting cylinder 37. The load-bearing slide 36 is located above the worktable 4. A sliding hole 361 is provided in the middle of the load-bearing slide 36. The support rod 31 is inserted into the sliding hole 361 and slidably connected to the sliding hole 361 to guide the movement of the support rod 31. The lifting cylinder 37 is located below the worktable 4. Its output end is provided with a support rod 31, which can drive the support rod to move along the pressing direction, thereby lifting the support positioning shaft. In this embodiment, the lifting cylinder 37 is an electric cylinder driven by a servo motor. In addition, a pressure sensor is provided between the support rod 31 and the lifting cylinder 37 to detect the pressing pressure.

[0027] like Figure 4-5 As shown, the load-bearing slide block 36 is also provided with a second slide hole 362 that is perpendicular to the first slide hole 361. The second slide hole 362 is connected to the insertion hole 311. The load-bearing locking block 33 also includes a guide part 332 and a sliding part 333 respectively disposed at both ends of the locking part 331. The bottom surfaces of the guide part 332, the locking part 331, and the sliding part 333 are flush with each other and are adapted to the bottom surface of the second slide hole 362. The top surfaces of the guide part 332 and the sliding part 333 are flat. The top surface of the guide part 332 is flush with the lower end of the locking part 331, and the top surface of the sliding part 333 is flush with the upper end of the locking part 331 and is adapted to the top surface of the second slide hole 362. The sliding part 333 of the guide part 332, locking part 331, and sliding part 333 is adapted to the second sliding hole 362. The guide load-bearing locking block 33 moves in a direction perpendicular to the pressing direction. The guide part 332 and the locking part 331 are both smaller than the second sliding hole 362, resulting in a small sliding contact area and smoother movement of the load-bearing locking block 33. The guide part 332 can also guide the load-bearing locking block 33 into the second sliding hole 362, which is convenient for installation. The locking part 331 does not contact the roller 35 before locking, which can further improve the smoothness of movement of the load-bearing locking block 33. The load-bearing locking block 33 achieves locking through the cooperation of the inclined surface and the arc surface. The locking force is large and stable, which can reduce the damage to the support rod 31, pressure sensor and other parts set along the pressing direction and the cylinder during pressing, ensure the pressing stability and extend the service life of the equipment.

[0028] like Figure 1-2 As shown, the positioning mechanism 2 includes a positioning base plate 21 and a positioning fixture. The positioning fixture is mounted on the positioning base plate 21 and is used to load the cylinder body. It includes a positioning base 22 and a positioning side plate 23. The positioning base 22 is provided with a plurality of positioning pins 24 that cooperate with the cylinder body. The positioning side plate 23 is located on one side of the positioning base 22. The side of the side of the side of the positioning base 22 is provided with a positioning surface that is adapted to at least one outer side surface of the cylinder body. The positioning base plate 21 and the positioning base 22 are provided with through holes coaxially arranged with the positioning shaft 32 to guide the positioning shaft to position. The positioning shaft can be inserted into the cylinder body to accurately dock with the assembly and precisely position and support the assembly.

[0029] The positioning mechanism 2 also includes a pressing assembly, which includes a pressing cylinder 25 and a pressing plate 26. The pressing cylinder 25 is fixed above the worktable 4 by a cylinder mounting seat. The pressing plate 26 is provided at its output end, and a pressing block 27 is provided at the end of the pressing plate 26. The pressing block 27 is elastic and can be pressed against the top of the cylinder body by the pressing cylinder 25 to fix the cylinder body and ensure that the cylinder body does not shift during pressing. In this embodiment, the pressing cylinder 25 is a rotary cylinder. When pressing down, the pressing cylinder drives the pressing plate to rotate and descend, pressing against the top of the cylinder body.

[0030] like Figure 1-4 As shown, the pressing mechanism 1 includes a pressing cylinder 11, a pressure plate 12, and an upper pressing head 13. The pressing cylinder 11 is fixed on the top of the pressing bracket 14, and the pressure plate 12 is provided at its output end. The pressing bracket 14 is fixedly connected to the worktable 4. The pressure plate 12 is slidably connected to the pressing bracket 14 through multiple guide rods. The upper pressing head 13 is located in the middle of the pressure plate 12 and is coaxially arranged with the positioning shaft 32. The upper pressing head 13 is movably connected to the rotor. Specifically, during pressing, the upper pressing head 13 abuts against the top surface of the rotor, thereby applying pressing force.

[0031] like Figure 3 As shown, the pressing mechanism 1 also includes a clamping assembly 15. The clamping assembly 15 includes a clamping seat 151 that can move elastically along the pressing direction. A clamping cylinder 152 is provided on the clamping seat 151. Two clamping plates 153 are provided at the output end of the clamping cylinder 152. A clamping hole adapted to at least part of the rotor shape is provided between the two clamping plates 153. In this embodiment, the clamping hole is adapted to the shape of the upper end of the rotor. During pressing, the two clamping plates 153 clamp and fix the upper end of the rotor. When the clamping hole is closed, it is coaxially set with the upper pressing head 13, so that the pressing is accurate.

[0032] The clamping assembly 15 also includes an upper pressure seat 154 and slide rails 155 and springs 156 that can drive the clamping seat 151 to move elastically along the pressing direction. The upper pressure seat 154 is located on one side below the pressure plate 12. On the side of the upper pressure seat 154 near the clamping seat 151, there are multiple slide rails 155 arranged along the pressing direction. The slide rails 155 are slidably connected to the sliders on the clamping seat 151. Multiple springs 156 are provided between the top of the clamping seat 151 and the upper pressure seat 154. The clamping seat 151 is elastically connected to the upper pressure seat 154 through the slide rails 155 and the springs 156. In addition, the upper pressure seat 154 is also provided with a stop to limit the movement stroke of the clamping seat 151 in the pressing direction to prevent the clamping seat 151 from detaching from the upper pressure seat 154.

[0033] In addition, such as Figure 1-2 and Figure 4 As shown, the pressing mechanism 1 also includes an adjustment component 16, which includes at least one adjustment plate. The adjustment plate is used to adjust the position of the upper pressing head 13 so that the upper pressing head 13, the closed clamping hole and the positioning shaft 32 are aligned to ensure alignment and improve pressing quality. Example 2

[0034] Based on the structure of Example 1, such as Figure 1-2 and Figure 4 As shown, the assembly device for the air pump rotor also includes a loading mechanism 5 located above the workbench 4. The loading mechanism 5 is used for loading and unloading cylinders and includes a conveying assembly. The conveying assembly is used to convey cylinders between the loading station and the pressing station. It includes a conveying electric cylinder 51, a guide rail 52, and a conveying seat 53. The conveying electric cylinder 51 is located above the workbench 4, and its output end is connected to the conveying seat 53 located above the conveying electric cylinder 51. Multiple guide rails 52 are provided on one side of the conveying electric cylinder 51 and are slidably connected to a slider located at the bottom of the conveying seat 53. The positioning fixture of the positioning mechanism 2 for loading cylinders is provided on the conveying seat 53, thereby conveying cylinders between the loading station and the pressing station. In this embodiment, the bottom of the conveyor seat 53 is provided with two slide plates 54 and two guide rails 52, which are slidably connected to the sliders provided at the bottom of the two slide plates 54 respectively. A groove is provided between the two slide plates 54, and the load-bearing slide 36 is located in the groove and is fitted with the groove with a gap, so that the positioning fixture does not conflict with the load-bearing slide when loading and unloading, making the whole equipment more compact and saving space.

[0035] The feeding mechanism 5 also includes a feeding assembly for feeding the rotor. The feeding assembly includes a gripper seat 55 and a feeding gripper 56. The gripper seat 55 is located on the conveyor seat 53, and the feeding gripper 56 is located on the top of the gripper seat 55. A loading hole that is adapted to at least part of the rotor's shape is provided between the two grippers of the feeding gripper 56. When the loading hole is closed, it is coaxially arranged with the positioning shaft 32, thereby ensuring the centering of the rotor feeding.

[0036] When loading the cylinder body, both the positioning fixture and the loading assembly are located on the conveyor seat 53 at the loading station. The cylinder body is placed onto the positioning fixture manually or by a robot, and the rotor is placed into the loading hole of the loading gripper 56. The loading gripper 56 clamps and fixes the rotor, completing the loading of the cylinder body and rotor. Then, the conveying assembly transports the cylinder body and rotor to the pressing station. The clamping assembly 15 descends, the clamping cylinder 152 engages with the loading gripper 56, the loading gripper 56 opens, and the rotor is transferred from the loading gripper 56 to the clamping cylinder 152, awaiting pressing. After pressing, the conveying assembly transports the assembled cylinder body to the loading station, awaiting unloading. The loading mechanism of this invention can simultaneously load the cylinder body and rotor, allowing the cylinder body and rotor to share the loading and conveying structure, saving costs.

[0037] The working principle of this invention is as follows: At the loading station, the cylinder body and rotor are respectively loaded into the loading holes of the positioning fixture and the loading gripper 56, and then transported to the pressing station. At the pressing station, the rotor on the loading gripper 56 is transferred to the clamping assembly 15 of the pressing mechanism 1. Then, the load-bearing locking mechanism 3 is activated, and the support rod 31 and the positioning shaft 32 move upward synchronously. When the pressure sensor on the load-bearing locking mechanism 3 detects that the lifting pressure reaches the set value, the support rod 31 and the positioning shaft 32 stop moving upward, and the positioning shaft... Insert the lower end of the eccentric shaft into the positioning support eccentric shaft. At this time, the load-bearing locking block 33 moves horizontally under the action of the locking cylinder 34. The locking part 331 moves to the bottom of the roller 35. When the pressure sensor detects a change in pressure value, the locking part 331 abuts against the roller 35. The two work together to lock the support rod 31, that is, to lock the support and positioning state of the positioning shaft 32, and distribute the pressure of pressing to the load-bearing locking block 33. At the same time, the pressing cylinder 11 continues to press downward until the rotor reaches the assembly position and the assembly is completed.

[0038] This invention enables the automatic assembly of the air pump rotor, which has a compact structure and is easy to operate. During pressing, the lower positioning state is locked by a load-bearing locking mechanism, which has a large and stable locking force. This not only reduces damage to parts and workpieces set along the pressing direction on the equipment and extends the service life of the equipment, but also ensures pressing stability and improves pressing quality.
