Description

Technical Field

[0001] This invention belongs to the technical field of wave washer assembly, and relates to an auxiliary assembly device for wave washers. Background Technology

[0002] In mechanical connection structures, corrugated washers are widely used in assembly systems with high reliability requirements, such as those in the automotive, aerospace, and heavy machinery industries, due to their unique elastic compensation properties and excellent anti-loosening effect. These washers typically have a wavy outer contour, providing stable preload in the axial direction and effectively preventing loosening of threaded connections caused by vibration or temperature changes. Furthermore, corrugated washers are usually added inside the coil during the coil manufacturing process.

[0003] Currently, the assembly of wave washers inside coils is usually done using an assembly line approach. During operation, a robotic arm transports the motor coil to the designated installation position, and then uses a suction cup structure to assemble the wave washer into the coil. The entire assembly is then transported to the lubrication oil filling station for further processing. In actual operation, the assembly of the wave washer and the filling of the lubricating oil are carried out separately, with an additional transfer process in between, making the operation more cumbersome and the assembly efficiency lower. Summary of the Invention

[0004] In view of this, the present invention provides a wave washer auxiliary assembly device.

[0005] The technical solution is as follows: A wave-shaped washer auxiliary assembly device includes a base, a rotating disk, a vibrating feeding disk, a drive motor, a feeding mechanism, and an oil injection mechanism. The rotating disk is rotatably connected to the top center of the base, and the vibrating feeding disk is installed on the top of the base. Multiple discharge ports are evenly spaced on the rotating disk, and the feeding holes of the vibrating feeding disk are aligned with the discharge ports. The drive motor is installed inside the top of the base, and the output shaft of the drive motor is connected to the rotating disk. The base is provided with a feeding mechanism for adding wave-shaped washers, and the rotating disk is provided with an oil injection mechanism for adding lubricating oil.

[0006] Furthermore, the feeding mechanism includes a guide plate, a sliding sleeve, a top sleeve, a fixed air bladder, and an elastic element two.

[0007] Furthermore, the feeding mechanism also includes an air guide cylinder, an air supply pipe, a piston rod, and an elastic element. Multiple air guide cylinders are evenly spaced along the circumference at the bottom of the rotating disk. An air supply pipe is connected to the air guide cylinder. The air supply pipe passes through the lower part of the sliding sleeve and communicates with the groove of the sliding sleeve. A piston rod is slidably connected inside the air guide cylinder. The end of the piston rod contacts the outside of the guide disk. An elastic element is connected between the piston rod and the sliding sleeve.

[0008] Furthermore, it also includes a magnet one and a magnet two. The bottom of the sliding sleeve is connected to a magnet one, and the top of the base is connected to a magnet two near the vibrating feeding plate. The downward-facing position of the magnet one and the upward-facing position of the magnet two have the same magnetic poles. The magnet one can be rotated to align with the magnet two.

[0009] Furthermore, the oil injection mechanism includes a liquid collection frame, an oil injection pipe, a sliding cylinder liner, a pusher ring, a piston block, an elastic element, and an injection pipe. The liquid collection frame is connected to the top center of the rotating disk. A recessed platform is provided in the bottom center of the liquid collection frame. Multiple oil injection pipes are evenly spaced at the bottom of the recessed platform. The number of oil injection pipes is the same as the number of sliding sleeves. A sliding cylinder liner is slidably connected inside the sliding sleeve. The sliding cylinder liner is connected to the rotating disk. An oil injection chamber is provided inside the sliding cylinder liner. The end of the oil injection pipe extends into the oil injection chamber inside the sliding cylinder liner. A piston block is slidably connected inside the sliding cylinder liner. An elastic element is connected between the piston block and the sliding cylinder liner. A pusher ring is connected to the lower part of the sliding sleeve. Multiple injection pipes are evenly spaced at the upper part of the sliding cylinder liner. The end of the injection pipe extends out of the sliding sleeve.

[0010] Furthermore, it also includes a feeding mechanism, which includes a support, a fixed arc plate, a movable arc plate, and a magnet. The support is connected to the top of the base, and the fixed arc plate is connected to the support. The movable arc plate is rotatably connected to the fixed arc plate. The fixed arc plate and the movable arc plate can store coils. The magnet is connected to the front side of both the fixed arc plate and the movable arc plate.

[0011] Furthermore, it also includes a discharge mechanism, which includes a guide frame, a pusher plate, and an extrusion column.

The threaded sleeve is threadedly engaged with the guide screw.

[0013] The beneficial effects are as follows: 1. In the process of assembling the wave washer, the present invention clamps the wave washer with a fixed airbag and inserts the wave washer into the coil. Then, the piston block squeezes the sliding cylinder liner, thereby injecting lubricating oil into the coil through the oil injection pipe. The lubricating oil and wave washer can be assembled at the same time, making the operation simpler and the assembly efficiency higher.

[0014] 2. In operation, the present invention only requires placing the coil between the fixed arc plate and the movable arc plate. Then, when the feeding port on the rotating disk rotates to the area below the fixed arc plate and the movable arc plate, the coil can fall into the feeding port, thereby realizing automatic coil addition without manual addition, making the operation more convenient.

Detailed Implementation

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0029] A wave washer auxiliary assembly device, such as Figures 1-9 As shown, the device includes a base 1, a rotating disk 2, a vibrating feeding disk 3, a drive motor 4, a feeding mechanism, and an oiling mechanism. The rotating disk 2 is rotatably connected to the top center of the base 1. The vibrating feeding disk 3 is installed on the left rear side of the top of the base 1. The rotating disk 2 has multiple discharge ports evenly spaced on it. The feeding holes of the vibrating feeding disk 3 are aligned with the discharge ports. The drive motor 4 is installed inside the top of the base 1. The output shaft of the drive motor 4 is connected to the rotating disk 2 so that the drive motor 4 can drive the rotating disk 2 to rotate. The base 1 is provided with a feeding mechanism for adding wave washers, and the rotating disk 2 is provided with an oiling mechanism for adding lubricating oil.

[0030] like Figures 2-5As shown, the feeding mechanism includes a guide plate 51, a sliding sleeve 52, a top sleeve 53, an air guide cylinder 54, an air supply pipe 55, a piston rod 56, an elastic element 57, a fixed air bladder 58, and an elastic element 59. The guide plate 51 is connected to the center of the top of the base 1. A break is provided on the rear side of the guide plate 51, and an arc-shaped transition is provided between the break and the edge of the guide plate 51. The sliding sleeve 52 is slidably connected to the discharge port of the rotating disk 2, and the sliding sleeve 52 can slide up and down along the rotating disk 2. The top sleeve 53 is slidably connected to the groove of the sliding sleeve 52. A fixed air bladder 58 is provided around the upper periphery of the top sleeve 53, and the interior of the top sleeve 53 communicates with the interior of the fixed air bladder 58. An elastic element 59, which is a connecting spring, is connected between the sliding sleeve 52 and the top sleeve 53. Multiple air guide cylinders 54 are evenly spaced around the bottom of the rotating disk 2. An air supply pipe 55 is connected to the air guide cylinder 54. The air supply pipe 55 passes through the lower part of the sliding sleeve 52 and connects to the groove of the sliding sleeve 52. A piston rod 56 is slidably connected inside the air guide cylinder 54. The piston rod 56 can move inside the air guide cylinder 54 to inject the gas in the air guide cylinder 54 into the groove and the top sleeve 53 through the air supply pipe 55. The end of the piston rod 56 contacts the outside of the guide disk 51. An elastic element 57, which is a connecting spring, is connected between the piston rod 56 and the sliding sleeve 52.

[0031] like Figure 2 and Figure 5 As shown, it also includes a magnet 61 and a magnet 62. The bottom of the sliding sleeve 52 is connected to the magnet 61, and the middle of the rear side of the top of the base 1 is connected to the magnet 62. The downward position of the magnet 61 and the upward position of the magnet 62 have the same magnetic poles. The magnet 61 can be rotated to align with the magnet 62.

[0032] When a wave-shaped washer needs to be inserted inside the coil, this device can be used for assembly. Initially, the piston rod 56 abuts against the guide plate 51, and the elastic element 57 is in a stretched state. During assembly, the coil is first placed at the feeding port, and then the wave-shaped washer is added to the vibrating feeding plate 3. The vibrating feeding plate 3 adds the wave-shaped washer to its feeding end. Then, the drive motor 4 is controlled to rotate the rotating plate 2. When the rotating plate 2 rotates the coil to below the feeding end of the vibrating feeding plate 3, magnet 61 also aligns with magnet 62. At this time... Magnet 61 and magnet 62, being of the same polarity, repel each other, causing magnet 61 and sliding sleeve 52 to move upwards. As sliding sleeve 52 moves upwards, it drives top sleeve 53 and fixed airbag 58 to move upwards as well. Top sleeve 53 and fixed airbag 58 extend into the feeding end of vibrating feed plate 3 and pass through the corrugated washer. At this time, piston rod 56 also moves to align with the break point of sliding sleeve 52. Then, under the action of elastic element 57, piston rod 56 resets. During reset, piston rod 56 compresses the gas in air guide cylinder 54, injecting the gas into the groove through air delivery pipe 55. Inside, after the gas enters the groove, it first passes through the top sleeve 53 into the fixed air bladder 58, causing the fixed air bladder 58 to expand and press against the inner wall of the wave-shaped washer. After the fixed air bladder 58 expands to its limit, more gas is injected into the top sleeve 53, causing the top sleeve 53 and the fixed air bladder 58 to move upward. The elastic element 59 is stretched, and the fixed air bladder 58 can move the wave-shaped washer upward as it moves upward. After moving upward, the control of the rotating disk 2 to continue rotating will cause the top sleeve 53 to detach from the feeding end of the vibrating feeding disk 3. At this time, the magnet 61 is no longer aligned with the magnetic field. Under the influence of gravity, the sliding sleeve 52 resets, which in turn drives the top sleeve 53 to reset. The reset of the top sleeve 53 then drives the fixed airbag 58 to add the waveform washer into the coil. At the same time, the piston rod 56 moves along the arc transition position of the guide plate 51. The movement of the piston rod 56 draws the gas from the groove and the fixed airbag 58 back into the air guide cylinder 54. In this way, the waveform washer can be added into the coil. There is no need for manual placement of the waveform washer during operation, making the operation more convenient.

[0033] like Figures 6-9As shown, the oil injection mechanism includes a liquid collection frame 81, an oil injection pipe 82, a sliding cylinder liner 83, a pusher ring 84, a piston block 85, an elastic element 86, and an oil injection pipe 87. The liquid collection frame 81 is connected to the top center of the rotating disk 2. A recessed platform is provided at the bottom center of the liquid collection frame 81. Multiple oil injection pipes 82 are evenly spaced at the bottom of the recessed platform. The number of oil injection pipes 82 is the same as the number of sliding sleeves 52. A sliding cylinder liner 83 is slidably connected inside the sliding sleeve 52. The sliding cylinder liner 83 is connected to the rotating disk 2. An oil injection chamber is provided inside the sliding cylinder liner 83. The end of the oil injection pipe 82... At the oil injection chamber extending into the sliding cylinder liner 83, a piston block 85 is slidably connected inside the sliding cylinder liner 83. An elastic element 86, which is a compression spring, is connected between the piston block 85 and the sliding cylinder liner 83. A pusher ring 84 is connected to the lower part of the sliding sleeve 52. The pusher ring 84 can move upward to contact the piston block 85 and push the piston block 85 to move. Multiple oil injection pipes 87 are evenly spaced on the upper part of the sliding cylinder liner 83. The ends of the oil injection pipes 87 protrude out of the sliding sleeve 52. When the sliding sleeve 52 moves upward, it can drive the ends of the oil injection pipes 87 to move upward into the coil.

[0034] During assembly, lubricating oil can be added to the sump 81. The lubricating oil in the sump 81 will be injected into the oil injection chamber in the sliding cylinder liner 83 through the oil injection pipe 82. When the sliding sleeve 52 moves upward, it can drive the pusher ring 84 to move upward, and at the same time, it can drive the upper part of the oil injection pipe 87 into the coil. When the pusher ring 84 moves upward, it can contact the piston block 85 and squeeze the piston block 85 to move upward. The elastic element 86 is compressed. When the piston block 85 moves upward, it can squeeze the oil injection chamber, thereby spraying the oil in the oil injection chamber into the coil through the oil injection pipe 87, thus achieving the effect of spraying lubricating oil into the coil. There is no need for manual lubricating oil spraying, making the operation more convenient.

[0035] like Figure 10 As shown, it also includes a feeding mechanism, which includes a support 71, a fixed arc plate 72, a movable arc plate 73, and a magnet 74. The support 71 is connected to the top left side of the base 1, and the fixed arc plate 72 is connected to the left side of the support 71. The movable arc plate 73 is rotatably connected to the fixed arc plate 72. The fixed arc plate 72 and the movable arc plate 73 can store coils. The front side of the fixed arc plate 72 and the movable arc plate 73 are both connected to magnets 74. The magnets 74 on the fixed arc plate 72 and the movable arc plate 73 attract each other and can fix the fixed arc plate 72 and the movable arc plate 73 together.

[0036] When it is necessary to add coils, the coils can be stacked between the fixed arc plate 72 and the movable arc plate 73. Then, the fixed arc plate 72 and the movable arc plate 73 are magnetically attracted together by the magnet 74. When the feeding port on the rotating disk 2 is rotated to be aligned with the bottom of the fixed arc plate 72 and the movable arc plate 73, the coils fall into the feeding port under the action of gravity, thus automatically adding coils and making the operation more convenient.

[0037] like Figure 11 As shown, it also includes a discharge mechanism, which includes a guide frame 91, a pusher plate 92 and an extrusion column 93. The guide frame 91 is connected to the top front side of the base 1. The pusher plate 92 is slidably connected to the discharge port of the rotary disk 2. The extrusion column 93 is connected to the pusher plate 92. Inclined surfaces are provided on both sides of the guide frame 91. The inclined surfaces of the guide frame 91 are located at the movement trajectory of the extrusion column 93.

[0038] After the wave washer is assembled, the rotating disk 2 continues to rotate, which can drive the extrusion column 93 to continue to move. When the extrusion column 93 moves, it can contact the guide frame 91 and be pushed upward by the guide frame 91. When the extrusion column 93 moves upward, it can drive the pusher plate 92 to move upward. When the pusher plate 92 moves upward, it can push out the assembled coil, making it more convenient to remove the coil without having to manually pry it out.

[0039] like Figure 12 As shown, it also includes a squeezing mechanism, which includes a guide screw 101, a squeezing disc 102 and a threaded sleeve 103. The guide screw 101 is connected to the middle of the recess of the liquid collection frame 81. The squeezing disc 102 is slidably connected to the guide screw 101. The threaded sleeve 103 is rotatably connected to the top of the squeezing disc 102. The threaded sleeve 103 is threadedly engaged with the guide screw 101.

[0040] When it is necessary to inject lubricating oil into the sliding cylinder liner 83, the threaded sleeve 103 can be rotated. The rotation of the threaded sleeve 103 drives the extrusion plate 102 to move downward through the thread. When the extrusion plate 102 moves, it can squeeze the lubricating oil in the accumulator 81 and inject the lubricating oil in the accumulator 81 into the sliding cylinder liner 83 through the oil injection pipe 82, so as to avoid the lubricating oil from depositing in the accumulator 81 due to its poor fluidity.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
