Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, and in particular to a plastic pipe joint assembly device. Background Technology

[0002] Pipe fittings play an indispensable role in pipe fittings, primarily used to connect two pipes together. Pipe fittings are generally divided into two types: flange fittings and socket fittings. Flanged fittings consist of two semi-circular flanges connected by bolts, and can be used to connect pipes of different diameters. Socket fittings consist of a fitting with a socket and a fitting with a spigot, and can be used to connect pipes of the same diameter. Gaskets are usually placed at the joint to ensure sealing performance and stability. ABS pipe fittings are among the most commonly used pipe connection elements, enjoying a good market share due to their excellent overall performance. However, most ABS pipe fittings also require gaskets at the connection point. Currently, gaskets are typically assembled manually. The worker holds the pipe fitting with one hand and inserts the gasket into the connection groove with the other, then presses it around the groove with a screwdriver or straight rod to complete the assembly. This method is obviously inefficient and labor-intensive. Therefore, it is necessary to design a highly efficient, fully automated plastic pipe fitting assembly device to address the shortcomings of existing technology. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] A plastic pipe fitting assembly device, such as Figure 1 and Figure 7 As shown, the system includes a processing table 1, which comprises an arched support 11 and side baffles 12 disposed on both sides of the upper end face of the arched support 11. The upper end face of the arched support 11 has vertical holes 13 extending from top to bottom, and the side baffles 12 have elongated holes 121. It should be noted that the side baffles 12 can be adjustable and disposed on the upper end face of the arched support 11. By adjusting the distance between the two side baffles 12, more sizes of pipe fittings can be accommodated. The pipe fittings are placed on the upper end face of the arched support 11 and are transferred from one end to the other by a feeding mechanism 2. For details, refer to [reference needed]. Figure 8 The feeding mechanism 2 includes a U-shaped frame 21, a slide rod 22, a push plate 23, and a long spring 24. The U-shaped frame 21 is located between the two side baffles 12 at the feeding end of the arched support 11. The slide rod 22 slides through the U-shaped frame 21 and slides along the feeding direction. The push plate 23 is located at one end of the slide rod 22 and abuts against the pipe joint to be processed. The long spring 24 is sleeved on the slide rod 22, and its two ends abut against the U-shaped frame 21 and the push plate 23, respectively. The long spring 24 mainly serves to store force and can also be replaced by other similar elastic components. The pipe joint placed on the upper surface of the arched support 11 is pushed by the feeding mechanism 2 to move to the other end and is assembled in sequence. When the outermost pipe joint is delivered to the bottom of the pick-and-place mechanism 4, it is just limited by the positioning mechanism 3.

[0024] For details, please refer to the following: Figure 6The positioning mechanism 3 includes a shaft support 31, a vertical shaft 32, a cross stop 33, a pulley 34, a shaft support plate 35, a short shaft 36, a first helical gear 37, and a second helical gear 38. The shaft support 31 is fixedly mounted on one side of the processing table 1. The vertical shaft 32 is rotatably mounted on the shaft support 31. The cross stop 33 is fixedly mounted on the upper end of the vertical shaft 32. The cross stop 33 is horizontally positioned, and when it rotates, it passes through the elongated hole 121 on the side baffle 12. When a pipe joint passes through, the outermost one is limited by the two adjacent intersecting rods of the cross stop 33, while the other pipe joints are blocked by one of the stops of the cross stop 33. The shaft support plate 35 is fixedly mounted on one side of the processing table 1, and the short shaft 36 rotates... The shaft is mounted on the support plate 35; the short shaft 36 is perpendicular to the support plate 35, and the first helical gear 37 is mounted on the short shaft 36 through a one-way bearing; it is particularly important to note that the first helical gear 37 is mounted through a one-way bearing, which allows the first helical gear 37 to rotate freely in one direction, but it will be obstructed when rotating in the opposite direction. The specific transmission method will be described in detail in the subsequent working principle. The second helical gear 38 meshes with the first helical gear 37 and is mounted on the stepped shaft 66 on the release assembly 6. The short shaft 36 and the vertical shaft 32 are connected by a pulley 34. A pulley is mounted on the short shaft 36 and the vertical shaft 32 respectively, and the two pulleys are connected by a belt.

[0025] like Figure 1-4 As shown, the pick-and-place mechanism 4 includes a frame 41, a rodless cylinder 42, a guide rod cylinder 43, a pusher block 431, a chip picker 44, a hopper 45, and a discharge plate 46. The rodless cylinder 42 is located at the upper end of the frame 41, and the piston moves linearly along the longitudinal direction of the guide rail of the rodless cylinder 42. In this embodiment, the rodless cylinder 42 can be replaced by a linear reciprocating mechanism, such as a linear slide rail, a linear motor, a reciprocating screw, etc. The guide rod cylinder 43 is located on one side of the piston of the rodless cylinder 42. The guide rod cylinder 43 is vertically arranged, and the piston rod extends and retracts in the vertical direction. The pusher block 431 is located on... The lower end of the piston rod of the guide rod cylinder 43 is connected to the chip taker 44, which is located on one side of the push block 431. The chip taker 44 is close to the processing table 1. The feeding plate 46 is located on one side of the frame 41. The feeding plate 46 is horizontally set. One end of the feeding plate 46 is provided with a recess 5 that matches the gasket. The hopper 45 is slidably connected to the feeding plate 46. The hopper 45 is open at both the upper and lower ends. The hopper 45 is slidably connected to the push block 431. The side wall of the push block 431 is provided with a vertical groove. A slider is slidably embedded in the groove. One side of the slider is fixedly connected to the outer shell of the hopper 45.

[0026] Figure 4This is a cross-sectional view of the film take-up machine 44, which includes a barrel shell 441, a barrel core 442, a short spring 443, and a pressure ring 444. The barrel shell 441 is fixedly mounted on one side of the push block 431. The barrel shell 441 is hollow inside, open at the lower end, and has an openable end cap at the upper end. The end cap is threadedly connected to the barrel shell 441. The barrel core 442 has an inverted frustum structure and is slidably mounted inside the barrel shell 441. The short spring 443 is mounted inside the barrel shell 441. The upper end of the short spring 443 is fixedly connected to the top of the barrel shell 441, and the lower end of the short spring 443 is fixedly connected to the upper end face of the barrel core 442. The pressure ring 444 is mounted at the lower end of the barrel shell 441 and is threadedly connected to the barrel shell 441.

[0027] like Figure 5 As shown, the release assembly 6 includes a first rack box 61, a push rod 62, a first spur rack 63, a shaft bracket 64, a stepped shaft 66, a spur gear 65, a second rack box 67, a second spur rack 68, a slider 681, a pressure rod 682, and a return spring 69. The upper end of the first rack box 61 is fixedly mounted on the bottom of the processing table 1. The lower end of the push rod 62 is fixedly connected to the upper end of the first spur rack 63 and slides together inside the first rack box 61. The push rod 62 extends upward and passes through the vertical hole 13. The second rack box 67 is fixedly mounted on one side of the frame 41. The lower end of the slider 681 is fixedly connected to the upper end of the second spur rack 68 and slides together inside the second rack box 67. The slider 681 extends upwards out of the second rack box 67. The return spring 69 is located at the bottom of the second rack box 67. The upper end of the return spring 69 abuts against the lower end of the second spur rack 68, and the lower end of the return spring 69 abuts against the bottom wall of the second rack box 67. The shaft frame 64 is located on one side of the processing table 1. The stepped shaft 66 is rotatably located at the lower end of the shaft frame 64. The spur gear 65 is coaxially fixedly connected to the stepped shaft 66. The spur gear 65 is located between the first spur rack 63 and the second spur rack 68. The spur gear 65 meshes with the first spur rack 63 and the second spur rack 68 respectively. A pressure rod 682 is provided directly above the slider 681. The pressure rod 682 is fixedly located at the bottom of the push block 431.

[0028] Working principle: For ease of understanding, it is explained here using... Figure 1 As a reference, the processing table 1 is the front side of the device, the location of the hopper 45 is the rear side of the device, the location of the feeding mechanism 2 is the left side of the device, and the opposite side is the right side.

[0029] After preparing the pipe fitting and gasket, pull the slide bar 22 to the left. The push plate 23 compresses the long spring 24, placing the pipe fitting on the upper surface of the arched support 11. After releasing the slide bar 22, the long spring 24 pushes the push plate 23 with its elastic force, causing the push plate 23 to press against the pipe fitting. The pipe fitting at the rightmost end is blocked by the cross stop bar 33. As the cross stop bar 33 rotates, it moves to the right, placing the gasket in the hopper 45. Then, start the rodless cylinder 42. At this time, the rodless cylinder 42 is active. The plug moves backward first, causing the pusher block 431 to move backward as well. The pusher block 431 then causes the hopper 45 to slide backward along the discharge plate 46. At this time, a washer at the bottom of the hopper 45 falls onto the recess 5. When the hopper 45 moves to the last end, the wafer picker 44 is just above the recess 5. Then, the piston rod of the guide rod cylinder 43 extends downward, causing the pusher block 431 and the wafer picker 44 to move downward. The core 442 of the wafer picker 44 passes through the middle of the washer and fits onto the washer. In the inner ring, the push block 431 and the outer shell of the hopper 45 slide relative to each other in the vertical direction, but do not separate. The piston rod of the guide rod cylinder 43 retracts, driving the chip taker 44 upward. At this time, the chip taker has completed the chip taker operation. Then, the piston of the rodless cylinder 42 moves forward first. When it reaches the front end, the chip taker 44 is just above the pipe joint restricted by the cross stop 33. Then, the piston rod of the guide rod cylinder 43 extends downward, driving the chip taker 44 downward. The barrel core 442 extends into the middle of the pipe joint, and the chip is just located in the installation groove of the pipe joint. When the chip taker 44 continues to move downward, the push rod 62 extends upward, abuts the barrel core 442 and retracts along the barrel shell 441, releasing the chip. The short spring 443 is squeezed and stored. During this process, the pressure ring 444 just presses the chip into the installation groove of the pipe joint. This realizes the automatic assembly of the chip and the pipe joint. Conversely, when the chip taker 44 moves upward, the short spring 443 drives the barrel core 442 to slide out.

[0030] Synchronously, when the wafer picker 44 lowers the pad, the pressure rod 682 presses down the slider 681, the second spur rack 68 slides downward along the second rack housing 67, driving the spur gear 65 to rotate clockwise. The return spring 69 is compressed and stores energy. The spur gear 65 then drives the first spur rack 63 to slide upward along the first rack housing 61, causing the push rod 62 to extend upward and press the barrel core 442 into the barrel shell 441. Simultaneously, the clockwise rotation of the spur gear 65 drives the stepped shaft 66 to rotate, and the clockwise rotation of the second helical gear 38 drives the first helical gear 37 to rotate. When the first helical gear 37 rotates, due to the one-way transmission characteristic of the one-way bearing, the first helical gear 37 rotates freely with the one-way bearing and does not drive the short shaft 36 to rotate. Conversely, when the pressure rod 682 moves upward, the return spring 69 rebounds, causing the second spur rack 68 to move upward, thereby causing the spur gear 65 to rotate counterclockwise and the second helical gear 38 to rotate counterclockwise, causing the first helical gear 37 to rotate clockwise. This, in turn, drives the short shaft 36 to rotate clockwise via the one-way bearing. Then, the vertical shaft 32 rotates clockwise via the pulley 34, which in turn drives the cross stop lever 33 to rotate clockwise. The cross stop lever 33 pushes the pipe joint with the gasket installed to the right, completing the push-away, and simultaneously moves the pipe joint on its left to the processing position. This achieves automated material conveying. This device is fully automated, quick and efficient to assemble, saving manpower and improving efficiency.
