Description

Technical Field

[0001] The invention relates to the technical field of short-circuit ring assembly, and in particular to automatic assembly equipment for stator short-circuit rings for motors. Background Art

[0002] The existing stator short-circuit ring assembly equipment is an automated equipment specially designed for the assembly of motor stator short-circuit rings. The equipment usually includes multiple installation stations and is equipped with a stator clamping mechanism, a short-circuit ring conveying mechanism, a receiving mechanism, a material picking mechanism and a material pressing mechanism, etc., to realize a series of operations such as automatic conveying, receiving, picking up, and pressing the short-circuit ring into the stator hole.

[0003] However, compared with the prior art, the following defects still exist in specific use: 1. During the feeding process of the stator short-circuit ring, since the staff manually assembles and loads the materials before feeding, when multiple stator short-circuit ring assemblies are placed on the conveyor belt, the assemblies will be congested at the conveyor belt port. Only after the subsequent pushing cylinder completes the single loading can the subsequent stator short-circuit ring assembly feeding and pressing steps be continued. In this process, the stator short-circuit ring assemblies are congested at the conveyor belt port, which will cause the entire feeding process to stagnate. In addition, the stator short-circuit ring assemblies are relatively precise components. Excessive congestion will cause mutual extrusion and collision between multiple stators, thereby causing wear on their outer surfaces, affecting the accuracy of subsequent pressing and installation of the stator short-circuit ring assemblies.

[0004] 2. In the prior art, in the stator short-circuit ring pressing and assembly process, in order to ensure the accuracy of the short-circuit ring pressing, a single stator short-circuit ring assembly is placed on a pressing platform and needs to rotate around for one circle. During this period, it will be pressed in turn by multiple pressing cylinders, and during each pressing operation, it has to rely on additional clamping cylinders for positioning, so as to prevent the stator short-circuit ring assembly from being displaced and ensure the accuracy of pressing. However, this pressing method will greatly increase the complexity and cost of the equipment. The use of multiple pressing cylinders and clamping cylinders not only makes the equipment structure complicated, but also increases the workload of equipment maintenance.

[0005] 3. During the pressing process of the stator short-circuit ring, since the pressing mold exerts a force every time it contacts the stator short-circuit ring, the stator short-circuit ring assembly will also generate a reaction force on the mold when the mold applies pressure to the stator short-circuit ring assembly to form it. The interaction of these forces will cause slight deformation, displacement and friction of the material on the contact surface. As the number of pressings increases, this slight friction accumulates, which will eventually affect the accuracy of the mold and the pressing quality of the stator short-circuit ring assembly, and leave scratches or uneven marks on the surface of the stator short-circuit ring assembly, which will require more frequent adjustments or replacements, reducing equipment production efficiency.

[0006] In view of this, the present invention proposes an automatic assembly device for stator short-circuit rings for motors to make up for and improve the deficiencies of the prior art. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides an automatic assembly device for stator short-circuit rings for motors to solve the technical problems raised in the above background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the present invention is: an automated assembly equipment for stator short-circuit rings for motors, including an operating machine, a controller is installed on the upper surface of the operating machine, a supply conveyor belt is installed on the front side of the controller, a feeding cylinder is installed on the conveying end of the supply conveyor belt, an assembly component is installed on the rear side of the feeding cylinder, an interval distribution mechanism is provided on the surface of the supply conveyor belt, and an anti-damage centering mechanism is provided inside the assembly component; the interval distribution mechanism is used to evenly separate and convey the stator short-circuit rings for supply; the anti-damage centering mechanism is used for integrated centering pressing and processing of short-circuit rings and reducing pressing wear.

[0009] Furthermore, the interval distribution mechanism includes a reciprocating wire shaft rotatably connected to the outer wall of the transmission shaft in the supply conveyor belt, a rectangular block is installed above the reciprocating wire shaft, the side wall of the rectangular block is fixedly connected to a barrier frame, the barrier frame is slidably connected to the side wall of the supply conveyor belt, and the end of the barrier frame away from the rectangular block is fixedly connected to an elastic gasket.

[0010] Furthermore, a roller ring is fixedly connected to the lower surface of the rectangular block corresponding to the outer wall of the reciprocating wire shaft, and the reciprocating wire shaft and the rectangular block are slidably connected via the roller ring.

[0011] Furthermore, the left side wall of the barrier frame has two branch shafts, the right side wall of the barrier frame has one branch shaft, and the spacings between the branch shafts on the left and right side walls of the barrier frame are equal.

[0012] Furthermore, the elastic gaskets are in the shape of an isosceles triangle as a whole, every two adjacent inclined edges of the elastic gaskets are kept parallel, and the elastic gaskets are made of rubber material.

[0013] Furthermore, the damage-proof centering mechanism includes a center column shaft fixedly connected to the output shaft end of the driving cylinder in the assembly component, the bottom of the center column shaft is threadedly connected with a turntable buckle, and the surface of the turntable buckle is evenly installed with linkage bent rods, and the end of the linkage bent rod away from the turntable buckle is fixedly connected with a splint, the bottom of the assembly component is fixedly connected with a liquid refilling tank, and the top of the liquid refilling tank is connected with a piston cylinder, and the piston cylinder is connected to the outer wall of the base placed in the assembly component, the interior of the piston cylinder is slidably connected with a piston rod, and the outer wall of the piston rod is sleeved with a reset spring, and the outer wall of the center column shaft is fixedly connected with a magnetic ring group.

[0014] Furthermore, the outer wall of the center column shaft is divided into two parts at the center point, the upper part of the center column shaft is a smooth outer wall, and the lower part of the center column shaft is a threaded outer wall, and a ball screw structure is formed between the threaded part of the center column shaft and the turntable buckle.

[0015] Furthermore, bending grooves are evenly formed on the surface of the turntable buckle, and the turntable buckle and the linkage bent rod are slidably connected via the bending grooves.

[0016] Furthermore, the two ends of the return spring are fixedly connected to the piston rod and the piston cylinder respectively, the piston rod is initially located at one end of the piston cylinder near the output port, lubricating oil is stored inside the liquid refilling tank, and a one-way valve is installed inside the connecting pipe between the liquid refilling tank and the piston cylinder.

[0017] Furthermore, the magnetic ring group is composed of a combination of no less than six magnetic plates, the end of the piston rod close to the magnetic ring group is made of iron material, the magnetic plates in the magnetic ring group and the piston rod are in the same horizontal plane, and the magnetism of the magnetic ring group gradually increases from bottom to top.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to improve the friction problem caused by the pressing process in the prior art, the present device prompts the piston cylinder to spray lubricating oil to the contact interface between the pressing mold and the placement base in an intermittent manner. In this process, the oil is sprayed out by using pressure, and then the suction force generated by the reaction force is cleverly used to ensure that the lubricating oil is evenly distributed between the mold and the base to form a thin oil film, thereby achieving an efficient boundary lubrication effect. First, through continuous and uniform oil film lubrication, the direct contact friction between the mold and the stator short-circuit ring assembly during the pressing process is effectively reduced, thereby delaying the decline in mold accuracy and extending the service life of the mold. Secondly, the existence of the oil film also greatly reduces the friction coefficient between the contact surfaces, reduces material deformation and displacement caused by friction, ensures the pressing accuracy and surface finish of the stator short-circuit ring assembly, and improves the overall quality of the product.

[0019] Compared with the scenario in which the stator short-circuit ring is subjected to multiple pressing processes in the prior art, the anti-friction lubrication by the device through suction to form a uniform oil film lubrication effect has the following advantages: First: the oil film lubrication of the device can evenly disperse the pressure during the pressing process, so that the force applied to the mold is more uniform, and can effectively prevent the mold from being deformed due to excessive local force, thereby maintaining the shape accuracy of the mold, and then ensuring that the size and shape of each stator short-circuit ring meet high standards.

[0020] Second: The presence of the oil film allows the surface of the assembly to smoothly contact the mold surface during pressing, and a higher surface finish helps to improve the electrical performance of the stator short-circuit ring, reduce surface resistance, and reduce power loss.

[0021] Third: The lubrication method of this device avoids fluctuations in the production process caused by problems with molds and assembly parts. It can ensure the stability of product quality and production speed during the production process, reduce the probability of interruption due to equipment failure, thereby greatly reducing equipment downtime and improving equipment utilization.

[0022] (2) Compared with the prior art that uses multiple cylinders to clamp the stator short-circuit ring assembly, the present device utilizes the up and down working state of the pressing cylinder itself to drive the linkage crankshaft to contract and move, so that the clamping plate can synchronously limit the stator short-circuit ring assembly, thereby reducing the additional clamping cylinder component. This limiting method significantly reduces the complexity of the equipment. From the perspective of cost investment, the present device simplifies the overall architecture of the equipment, reduces unnecessary coupling of mechanical and pneumatic subsystems, and makes the equipment structure more compact and simple, which is convenient for equipment installation, commissioning and subsequent upgrades and renovations. From the perspective of spatial layout, the present device is conducive to the reasonable arrangement of more equipment in a limited factory space, and also provides a more spacious working space for operators and maintenance personnel around the equipment, which helps to improve work efficiency and reduce safety hazards.

[0023] (3) In order to solve the problem of blockage in the conveying of stator short-circuit ring assemblies in the prior art, the present device relies on the self-rotation of the transmission shaft to evenly separate the stator short-circuit ring assemblies and intermittently convey the materials one by one without the need for an additional driving source, thereby ensuring that the stator short-circuit ring assemblies can be conveyed at a stable rhythm, avoiding stagnation of material conveying due to congestion, and ensuring that each stator short-circuit ring assembly can maintain a good initial state when entering the pressing process, so that the evenly separated and undamaged stator short-circuit ring assemblies can be more accurately matched with the pressing mold, reducing the pressing error caused by factors such as surface unevenness or shape deformation, thereby improving the accuracy of the pressing and installation of the stator short-circuit ring assemblies.

[0024] Compared with the prior art which only relies on the conveyor belt for feeding, the improved device adopts the intermittent feeding method one by one, which makes the feeding process of each stator short-circuit ring assembly smoother and more efficient, thereby reducing the time consumption of the feeding link, helping to improve the rhythm of the entire production process, and the evenly separated feeding method makes the load of the pushing cylinder more stable. It only needs to push a single stator short-circuit ring assembly at a fixed rhythm, which helps to reduce vibration and pressure fluctuations during equipment operation.

[0025] Among them, by installing an elastic gasket at the end of the branch shaft, when the subsequent stator short-circuit ring assembly contacts it, physical damage such as scratches and dents caused by hard contact can be avoided, and the elastic gasket is used to absorb the impact force between the stator short-circuit ring assembly and the structure, ensuring that the external force applied to the stator short-circuit ring assembly during the feeding process is relatively uniform and gentle, thereby protecting the overall integrity of the stator short-circuit ring assembly.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that the structures and working principles of the above-mentioned operating machine 1, controller 11, supply conveyor belt 12, feeding cylinder 13 and assembly component 14 belong to the prior art and will not be repeated here.

[0041] Example 1: Please refer to Figure 1 As shown, an automatic assembly device for stator short-circuit rings for motors includes an operating platform 1, a controller 11 is installed on the upper surface of the operating platform 1, a supply conveyor belt 12 is installed on the front side of the controller 11, a feeding cylinder 13 is installed on the conveying end of the supply conveyor belt 12, an assembly component 14 is installed on the rear side of the feeding cylinder 13, a spacing distribution mechanism 2 is arranged on the surface of the supply conveyor belt 12, and an anti-damage centering mechanism 3 is arranged inside the assembly component 14.

[0042] The replenishing conveyor belt 12 is composed of a transmission belt and a transmission shaft, and the assembly component 14 is composed of a driving cylinder, a plurality of pressing cylinders, a pressing mold, a placement base and other components.

[0043] Please refer to Figures 2 to 5 As shown, the spacing distribution mechanism 2 includes a reciprocating wire shaft 21 rotatably connected to the outer wall of the transmission shaft in the supply conveyor belt 12, a rectangular block 22 is installed above the reciprocating wire shaft 21, and the side wall of the rectangular block 22 is fixedly connected to a blocking frame 23, the blocking frame 23 is slidably connected to the side wall of the supply conveyor belt 12, and the end of the blocking frame 23 away from the rectangular block 22 is fixedly connected to an elastic gasket 24.

[0044] It should be noted that the lower surface of the rectangular block 22 is fixedly connected to the outer wall of the reciprocating wire shaft 21 with a roller ring, the reciprocating wire shaft 21 and the rectangular block 22 are slidably connected through the roller ring, the left side wall of the barrier frame 23 has two branch shafts, the right side wall of the barrier frame 23 has one branch shaft, and the spacing between the branch shafts on the left and right side walls of the barrier frame 23 is equal.

[0045] Specifically, Figure 3 As shown, the branch shafts of the side wall of the barrier frame 23 are initially separated on the surface of the supply conveyor belt 12. When the stator short-circuit ring is transmitted to the output port position through the supply conveyor belt 12, during this process, the reciprocating wire shaft 21 will keep synchronous rotation with the transmission shaft in the supply conveyor belt 12. Since the reciprocating wire shaft 21 and the rectangular block 22 are slidably connected through the roller ring, and the thread groove on the outer wall of the reciprocating wire shaft 21 is cross-convoluted, the roller ring will move back and forth along the thread groove on the outer wall of the reciprocating wire shaft 21, and then through the subsequent reciprocating movement of the barrier frame 23, The stator short-circuit rings on the surface of the supply conveyor belt 12 are evenly separated, and the stator short-circuit rings are conveyed one by one in an intermittent manner, ensuring that the short-circuit rings can be conveyed at a stable rhythm, avoiding material stagnation caused by congestion, and through the uniform spacing of the barrier frame 23, each short-circuit ring can maintain a good initial state when entering the pressing process, so that the evenly separated and undamaged short-circuit rings can be more accurately matched with the pressing mold, reducing the pressing error caused by factors such as surface unevenness or shape deformation, thereby improving the accuracy of the short-circuit ring pressing and installation.

[0046] It should be noted that the elastic gasket 24 is in the shape of an isosceles triangle as a whole, every two adjacent inclined sides of the elastic gasket 24 are kept parallel, and the elastic gasket 24 is made of rubber material.

[0047] Specifically, by installing an elastic gasket 24 at the end of the branch shaft of the side wall of the barrier frame 23, physical damage such as scratches and dents caused by hard contact can be avoided when the subsequent short-circuit ring contacts it, and the elastic gasket 24 absorbs the impact force between the short-circuit ring and the structure, ensuring that the external force on the short-circuit ring during the feeding process is relatively uniform and gentle, thereby protecting the overall integrity of the short-circuit ring.

[0048] Example 2: Based on Example 1, please refer to Figure 6 and Fig.12As shown, the damage-proof centering mechanism 3 includes a center column shaft 31 fixedly connected to the output shaft end of the driving cylinder in the assembly component 14, the bottom of the center column shaft 31 is threadedly connected with a turntable buckle 32, and the surface of the turntable buckle 32 is evenly installed with a linkage bent rod 33, and the end of the linkage bent rod 33 away from the turntable buckle 32 is fixedly connected with a clamping plate 34, the bottom of the assembly component 14 is fixedly connected with a liquid refilling tank 3401, and the top of the liquid refilling tank 3401 is connected with a piston cylinder 35, and the piston cylinder 35 is connected to the outer wall of the base placed in the assembly component 14, the interior of the piston cylinder 35 is slidably connected with a piston rod 36, and the outer wall of the piston rod 36 is sleeved with a reset spring 37, and the outer wall of the center column shaft 31 is fixedly connected with a magnetic ring group 38.

[0049] It should be noted that the two ends of the reset spring 37 are fixedly connected to the piston rod 36 and the piston cylinder 35 respectively. The piston rod 36 is initially located at one end of the piston cylinder 35 near the output port. Lubricating oil is stored inside the liquid refilling tank 3401. A one-way valve is installed inside the connecting pipe between the liquid refilling tank 3401 and the piston cylinder 35. The magnetic ring group 38 is composed of a combination of no less than six magnetic plates. The end of the piston rod 36 near the magnetic ring group 38 is made of iron material. The magnetic plates in the magnetic ring group 38 are on the same horizontal plane as the piston rod 36, and the magnetism of the magnetic ring group 38 gradually increases from bottom to top.

[0050] Specifically, Figure 8 and Fig. 9As shown, when the stator short-circuit ring is transported by the supply conveyor belt 12 and is pushed to the placement base in the assembly component 14 by the feeding cylinder 13, the driving cylinder in the assembly component 14 will drive the pressing mold to move downward together to press the stator short-circuit ring. The lower surface of the pressing mold in the assembly component 14 is installed with a sealing plate. When the sealing plate contacts the placement base, a relatively sealed space will be formed between the pressing mold and the placement base. When the driving cylinder in the above-mentioned assembly component 14 moves downward, the middle column shaft 31 will move downward synchronously with it. At this time, with the magnetic attraction between the magnetic ring group 38 and the piston rod 36, the piston rod 36 will gradually move toward the direction of the magnetic ring group 38. At this time, the space inside the piston cylinder 35 gradually becomes larger, and in this process, the air pressure inside the piston cylinder 35 is less than the air pressure outside the piston cylinder 35, thereby generating suction inside the piston cylinder 35. Since a one-way valve is installed inside the connecting pipe between the refilling tank 3401 and the piston cylinder 35, when the suction acts on the surface of the one-way valve, it will cause it to move from The closed state is changed to the open state, thereby ensuring that the refilling tank 3401 and the piston cylinder 35 are connected to each other, and in the process of generating suction, the suction will continuously draw the lubricating oil inside the refilling tank 3401 into the piston cylinder 35. At the same time, when the piston rod 36 relies on the rebound force of the return spring 37 to return to its original position, at this time, the space inside the piston cylinder 35 gradually becomes smaller, and at this time the air pressure inside the piston cylinder 35 is greater than the air pressure outside the piston cylinder 35, thereby generating thrust inside the piston cylinder 35, and when the thrust acts on the surface of the one-way valve, it will cause it to change from the open and closed state during the suction process to the closed state, and in the process of generating thrust, the lubricating oil inside the piston cylinder 35 is synchronously sprayed between the pressing mold and the placement base, and then the pressure is used to drive the oil to spray, and then the suction generated by the reaction force is cleverly used to ensure that the lubricating oil is evenly distributed between the mold and the base, forming a thin oil film, achieving an efficient boundary lubrication effect, and effectively reducing the direct contact friction between the mold and the stator short-circuit ring assembly during the pressing process.

[0051] It should be noted that the outer wall of the center column shaft 31 is divided into two parts at the center point. The upper part of the center column shaft 31 is a smooth outer wall, and the lower part of the center column shaft 31 is a threaded outer wall. A ball screw structure is formed between the threaded part of the center column shaft 31 and the turntable buckle 32. The surface of the turntable buckle 32 is evenly penetrated with curved grooves, and the turntable buckle 32 and the linkage curved rod 33 are slidingly connected through the curved grooves.

[0052] Specifically, Fig.10 and Fig.11As shown, when the middle column shaft 31 moves downward synchronously with the driving cylinder in the assembly component 14, since the structure between the middle column shaft 31 and the turntable buckle 32 is similar to that of a ball screw, and the pitch of the lower half of the middle column shaft 31 is equal to the inner diameter of the turntable buckle 32, and the angle between the tangent of the thread and the cylinder and the horizontal plane is greater than 45 degrees, when the middle column shaft 31 moves downward, the vertical downward force can be smoothly transmitted to the turntable buckle 32, thereby driving it to rotate. During the rotation of the turntable buckle 32, the curved groove on its surface will continuously squeeze the outer wall of the linkage bent rod 33 due to its own rotation, thereby The extrusion force drives the linkage bent rod 33 to move linearly along the lower surface of the assembly component 14 until it drives the clamping plate 34 to move and fit against the outer wall of the short-circuit ring, thereby clamping it to prevent deviation. Compared with the prior art that uses multiple cylinders to clamp the short-circuit ring, the present device utilizes the up and down working state of the pressing cylinder itself to drive the linkage bent rod 33 to contract and move, so that the clamping plate 34 synchronously limits the short-circuit ring, thereby reducing the additional clamping cylinder component, thereby reducing unnecessary coupling of mechanical and pneumatic subsystems, making the equipment structure more compact and simple, and facilitating the installation, commissioning and subsequent upgrading of the equipment.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
