Description

Technical Field

[0001] This utility model relates to the field of plastic parts and pipe fittings pressing technology, specifically to a pneumatic plastic parts and pipe fittings pressing device. Background Technology

[0002] In current plastic component and pipe fitting connection and installation operations, the traditional method involves first fitting the plastic component onto one end of the pipe fitting, and then having workers use tools such as rubber mallets to strike the plastic component, thus forcing it into the pipe fitting and achieving the connection. Manually striking the plastic component with a rubber mallet is a slow process, especially in mass production situations. The repetitive striking motion over extended periods is labor-intensive and fails to meet production demands. Furthermore, workers rely on the sound and feel of the striking action to determine if the plastic component is properly fitted, which is highly subjective. Different workers, and even the same worker at different times, may have different judgments, leading to inconsistent product quality and affecting the overall quality and stability of the product. Therefore, there is an urgent need to provide a pneumatic plastic component and pipe fitting pressing device to solve these problems. Utility Model Content

[0019] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0020] A pneumatic plastic part and pipe fitting pressing device includes a base 1, a baffle 2 installed at one top end of the base 1, and a translation component installed at the other top end of the base 1. A cylinder 3 is installed on the translation component, and a pressure plate 4 is installed at the output end of the cylinder 3. A placement and positioning mechanism is installed on the top of the base 1 between the pressure plate 4 and the baffle 2. The placement and positioning mechanism includes a clamping plate 5, a replacement component, and a clamping component. The replacement component is used to replace the clamping plate 5, and the clamping component is used to drive the clamping plate 5 to clamp the pipe fitting. In use, the device can replace the clamping plate 5 through the replacement component, and the clamping component drives the clamping plate 5 to clamp the pipe fitting. The structure is simple and the operation is convenient. There is no need for the operator to use a rubber hammer to knock and press the plastic part that is initially connected to the end of the pipe fitting. The cylinder 3 can be used to directly push and press the plastic part. The device can also replace the appropriate clamp with the corresponding pipe fitting size for positioning operation according to actual needs, which further improves its practicality.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly includes multiple sets of fixed frames 6 arranged and installed on the top of the base 1. A first motor 7 is installed on one end of the inner wall of the fixed frame 6, and a first threaded rod 8 is rotatably connected to the other end of the inner side of the fixed frame 6. The driving end of the first motor 7 is fixedly connected to the other end of the first threaded rod 8. A connecting plate 9 is threadedly connected to the outer side of the first threaded rod 8. A sliding groove is opened on one side of the inner wall of the fixed frame 6 located on the first threaded rod 8. A sliding plate that is slidably connected to the sliding groove is installed on one side of the connecting plate 9. First, the pipe is placed on the inner side of the lower clamping plate 5, so that one end of the pipe abuts against the outer wall of the baffle 2. The first motor 7 is started to drive the first threaded rod 8 to rotate. With the help of the sliding plate and the sliding groove, the connecting plate 9 is moved smoothly. The component at the other end of the connecting plate 9 can drive the upper clamping plate 5 to move down to clamp the pipe.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the translation assembly includes a connecting frame installed on the other end of the outer wall of the base 1. An adjusting cylinder 19 is installed on one end of the inner side of the connecting frame. A second threaded rod 20 is rotatably connected to the inner side of the adjusting cylinder 19. An adjusting plate 21 is threadedly connected to the outer side of the second threaded rod 20. The adjusting plate 21 and the adjusting cylinder 19 are slidably connected. A second motor is installed at the top of the connecting frame. The driving end of the second motor extends to the inner side of the adjusting cylinder 19 and is fixedly connected to one end of the second threaded rod 20. The other end of the adjusting plate 21 is fixedly connected to one side of the cylinder 3. Then, the plastic part is sleeved on the end of the pipe. Starting the second motor can drive the second threaded rod 20 to rotate, so that the adjusting plate 21 slides inside the adjusting cylinder 19, thereby adjusting the height position of the cylinder 3 and the pressure plate 4 to a suitable pushing height. Starting the cylinder 3 drives the pressure plate 4 to move closer to the pipe and the plastic part, squeezing them together to achieve the pressing operation.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the replacement assembly includes multiple sets of mating seats 10 respectively installed on the other end of the connecting plate 9 and the inner wall of the protruding end of the fixing frame 6. A rubber pad 11 is embedded in the top of the mating seat 10. A locking groove is opened on one side of the top of the rubber pad 11. A locking plate 12 that is slidably connected to the locking groove is installed on one end of the bottom of the clamping plate 5. A movable groove is opened inside the mating seat 10 on one side of the locking groove. A movable block 13 is slidably connected inside the movable groove. Corresponding inclined surfaces are opened on the opposite ends of the movable block 13 and the locking plate 12. A pushing groove is opened on the outer wall of the movable block 13 at its inclined surface. A rotating rod is rotatably connected to one end of the inner side of the pushing groove. A pushing plate 14 is fixedly sleeved on one end of the outer wall of the rotating rod. A torsion spring 15 is installed between the other end of the rotating rod and the pushing groove. A splicing groove that is slidably connected to the pushing plate 14 is opened on the outer wall of the movable block 13 at its inclined surface. A first spring is installed between one end of the outer wall of the movable block 13 and the inner wall of the movable groove. A limiting groove is provided inside the docking seat 10 on the other side of the movable groove. A limiting block 16 that is slidably connected to the limiting groove is installed on the outer wall of the movable block 13 on one side of the first spring. The cross-section of the limiting block 16 and the limiting groove is T-shaped. Further, the clamping plate 5 is overlapped on the surface of the rubber pad 11, so that the locking plate 12 is inserted into the inner side of the locking groove. The locking plate 12 contacts the movable block 13, and the inclined surfaces contact and abut against each other. The movable block 13, together with the limiting groove and the limiting block 16, moves back stably to squeeze the first spring back. When the locking plate 12 moves, it will also press the push plate 14 to drive the rotating rod and the torsion spring 15 to twist and compress. The rubber pad 11 is compressed in this process. After the splicing groove on the locking plate 12 is close to the push groove, the torsion spring 15 can drive the push plate 14 to pop out to the inner side of the splicing groove. At this time, after the clamping plate 5 is released, the rebound of the rubber pad 11 and the first spring makes the push plate 14 tightly abut against the inner wall of the splicing groove, thus completing the combined use of the clamping plate 5.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a pull rod 17 is installed at the other end of the limiting block 16. A groove extending to the inside of the limiting groove is opened on one side of the outer wall of the docking seat 10. The groove and the pull rod 17 are slidably connected. A pull ring is rotatably connected to the end of the pull rod 17 that extends to the outside of the groove. The pull ring is made of rubber. A hook rod 18 is installed on the other side of the groove on the outer wall of the docking seat 10. Furthermore, after assembly, the pull ring body can be stretched and hung obliquely on the hook rod 18 to enhance the positioning effect. When the clamping plate 5 needs to be replaced, the pull ring can be fastened to drive the pull rod 17 to slide inside the groove, thereby pulling the limiting block 16 to drive the movable block 13 to retract again inside the movable groove. The push plate 14 can be directly dragged out from the inside of the splicing groove laterally. At this time, the reset of the rubber pad 11 can lift the clamping plate 5 and the locking plate 12 a certain distance. Then the pull ring can be released to remove the clamping plate 5.

[0025] The implementation principle of the pneumatic plastic and pipe fitting pressing device in this application embodiment is as follows: The pipe fitting is placed inside the lower clamping plate 5, with one end of the pipe fitting abutting against the outer wall of the baffle 2. The first motor 7 is started to drive the first threaded rod 8 to rotate, which, together with the sliding plate and sliding groove, drives the connecting plate 9 to move smoothly. The component at the other end of the plate can drive the upper clamping plate 5 to move down, clamping the pipe fitting. Then, the plastic part is placed on the end of the pipe fitting. The second motor is started to drive the second threaded rod 20 to rotate, causing the adjusting plate 21 to slide inside the adjusting cylinder 19, thereby adjusting the height of the cylinder 3 and the pressure plate 4 to a suitable pushing height. The cylinder 3 is started to drive the pressure plate 4 to move closer to the pipe fitting and the plastic part, squeezing them together to achieve the pressing operation. The clamping plate 5 is placed on the surface of the rubber pad 11, so that the locking plate 12 is inserted into the locking groove. The locking plate 12 contacts the movable block 13, with the inclined surfaces contacting and abutting each other. The movable block 13 is equipped with The stable return movement of the limiting groove and limiting block 16 compresses and retracts the first spring. The movement of the locking plate 12 also presses against the push plate 14, causing the rotating rod and torsion spring 15 to twist and compress. The rubber pad 11 is compressed during this process. Once the splicing groove on the locking plate 12 is close to the push groove, the torsion spring 15 can push the push plate 14 out to the inside of the splicing groove. At this point, after releasing the clamping plate 5, the rebound of the rubber pad 11 and the first spring causes the push plate 14 to press tightly against the inner wall of the splicing groove, completing the process. The clamping plate 5 can be used in combination. After combination, the pull ring body can be stretched and hung diagonally on the hook rod 18 to enhance the positioning effect. When the clamping plate 5 needs to be replaced, the pull ring can be fastened to drive the pull rod 17 to slide inside the groove, thereby pulling the limit block 16 to drive the movable block 13 to retract again inside the movable groove. The push plate 14 can be directly pulled out from the inside of the splicing groove laterally. At this time, the reset of the rubber pad 11 can lift the clamping plate 5 and the locking plate 12 a certain distance. Then the pull ring can be released to remove the clamping plate 5.

The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
