Description

Technical Field

[0001] The invention relates to a tube grinding device, in particular to a tube grinding device for producing and processing branch nozzles. Background Art

[0002] A branch nozzle, also known as a nozzle branch, is a short tube located in front of the nozzle that supplies water to it. A common branch nozzle is the snap-in type. To use it, a slot is drilled in the main pipe where the branch pipe is to be connected. The snap-in nozzle is then inserted into the slot and connected by welding. As fluid flows through a piping system, friction occurs between the fluid and the inner wall of the pipe. As the pipe ages, the inner wall wears due to friction, resulting in a decrease in the pipe's inner diameter, a reduction in flow rate, and increased energy consumption. Therefore, before installing the snap-in branch nozzle, the end face where it is inserted into the slot needs to be polished, typically using a pipe grinding device.

[0003] In order to improve the grinding efficiency, the existing tube grinding device usually grinds the end faces of multiple embedded branch nozzles at one time. However, this grinding method has a great defect. If there are a few workpieces that fail to be polished in one grinding process, they are usually removed and then re-grinded, or they are not removed and re-grinded together with the workpieces that pass the grinding. However, either method will cause a waste of manpower and material resources. Therefore, how to adjust the unqualified workpieces together as much as possible for re-grinding during the grinding of the end faces of multiple embedded branch nozzles at one time is a difficult problem that we urgently need to solve.

[0004] Therefore, those skilled in the art provide a tube grinding device for producing and processing branch nozzles to solve the problems raised in the above background technology. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] As mentioned in the background of this application, the inventors have found that Figure 9 and Figure 10 As shown, when using the existing embedded branch pipe nozzle 23, a hole groove is opened on the main pipe 54 to which the branch pipe is to be connected, and then the embedded branch pipe nozzle 23 is inserted into the hole groove and connected together by welding. It should be noted that during the flow of fluid in the pipeline system, friction will be generated between the fluid and the inner wall of the pipeline. As the pipeline is used for a longer time, the inner wall of the pipeline will wear due to friction, which will lead to a decrease in the inner diameter of the pipeline, a decrease in flow rate, and an increase in energy consumption. The embedded branch pipe nozzle 23 is different from ordinary pipelines. It has a relatively large end face connected to the main pipe 54. Therefore, before installation, the embedded branch pipe nozzle 23 needs to be polished on the end face of the embedded branch pipe nozzle 23 inserted into the hole groove, usually using a pipe grinding device. In order to improve the grinding efficiency, the existing tube grinding device usually grinds the end faces of multiple embedded branch nozzles 23 at one time. However, this grinding method has a great defect. If there are a few workpieces that fail to be polished in one grinding process, they are usually removed and then re-grinded, or they are not removed and re-grinded together with the workpieces that pass the grinding. However, no matter which method is used, it will cause a waste of manpower and material resources. Therefore, how to adjust the unqualified workpieces together and re-grind them as a group as possible during the grinding of the end faces of multiple embedded branch nozzles 23 at one time is a difficult problem that we urgently need to solve.

[0033] In order to solve the above-mentioned defects, the present application discloses a tube grinding device for the production and processing of branch nozzles, which adopts a plurality of rotary feeding assemblies, and each rotary feeding assembly can be placed on four embedded branch nozzles 23. During the grinding process, the camera 37 collects images of the grinding conditions of each embedded branch nozzle 23, transmits the collected images to the background control terminal, and determines which workpiece is unqualified and the position of the unqualified workpiece through image recognition. After completing the first grinding of all embedded branch nozzles 23, the driving mechanism drives each rotary feeding assembly to rotate, and then adjusts the unqualified workpieces into a group side by side as much as possible, and then performs grinding on this group of workpieces. A second grinding is performed, and after the grinding is completed, image collection and recognition are performed again to determine the unqualified workpieces again. Subsequently, the driving mechanism is used to drive the various rotating feeding components to rotate, and the unqualified workpieces are adjusted to a group side by side as much as possible, and this group of workpieces is ground for the third time, and finally all the workpieces are sent out. In this way, during the one-time grinding of the end faces of multiple embedded branch nozzles 23, the unqualified workpieces can be adjusted together and put into a group for re-grinding, thereby saving manpower and material resources. At the same time, the grinding of qualified workpieces is minimized without the need for early unloading, and the loss of the ceramic grinding roller 42 by the qualified workpieces is reduced.

[0040] In this embodiment: the intermittent pushing component specifically includes: a box body 43 fixed to one side of the ceramic grinding roller 42, a pushing chamber 44 is opened inside the box body 43, and the inside of the pushing chamber 44 is rotatably connected to a rotating disk 45, the outer side of the rotating disk 45 is fixedly connected to a rotating arm 46, and the end of the rotating arm 46 is rotatably connected to a roller 47, one side of the rotating disk 45 is movably connected to a transmission block 49, and one side of the transmission block 49 is fixedly connected to a push rod 50, one end of the push rod 50 passes through the box body 43 and contacts the end of the ceramic grinding roller 42, and the outside of the push rod 50 is sleeved with a fourth spring column 51, the two ends of the fourth spring column 51 are respectively fixedly connected to the inner wall of the pushing chamber 44 and the side of the transmission block 49, the position of the inner wall of the pushing chamber 44 corresponding to the rotating disk 45 is fixedly connected to a rotating motor 48, and the output shaft of the rotating motor 48 is fixedly connected to the rotating disk 45. The intermittent pushing component of the present application adopts push-pull grinding, which can better fit the arc-shaped end face of the embedded branch nozzle 23 compared with the traditional rolling grinding. At the same time, in addition, this grinding method does not require the ceramic grinding roller 42 to be fixed, which is convenient for timely replacement of the ceramic grinding roller 42 when needed.

[0041] In this embodiment, a support plate 52 is fixedly connected to the top of the transmission block 49, and an optical axis 53 is fixedly connected above the transmission block 49, and the optical axis 53 passes through the support plate 52. The use of the support plate 52 and the optical axis 53 not only provides support for the transmission block 49, but also improves the stability of the movement of the transmission block 49.

[0042] In this embodiment, the top surface of the machine body 1 is provided with a strip groove 55 communicating with the processing chamber 2. The strip groove 55 is used to put in or take out the embedded branch nozzle 23.

[0043] The working principle of the present invention is as follows: when in use, first, the staff puts the embedded branch nozzle 23 to be polished into the clamping mechanism of each guide rod 5 through the strip groove 55, specifically: insert one end of the embedded branch nozzle 23 into the clamping groove 11 until one end of the embedded branch nozzle 23 moves toward the insulating plate 14 against the electromagnet 13 and contacts the conductive connector 15. At this time, the electromagnet 13 is energized to generate magnetism to firmly adsorb the embedded branch nozzle 23, and the first spring column 17 is compressed. During the movement of the electromagnet 13, the second spring column Under the elastic force of 20, the electromagnet 13 and the lower support plate 22 produce an inclined surface effect, and the lower support plate 22 continues to move closer to the electromagnet 13 until the inclined surface of the electromagnet 13 is completely in contact with the inclined surface of the lower support plate 22. At this time, the electromagnet 13 is also energized to generate magnetism, thereby adsorbing the lower support plate 22. At the same time, as the lower support plate 22 moves, the vertical plate 19 and the upper support plate 21 also move with it. The upper support plate 21 extends into the slot 11 to clamp the embedded branch nozzle 23 from both sides, further improving the stability of the entire embedded branch nozzle 23.

[0044] After all the embedded branch nozzles 23 are placed on the clamping mechanisms, the cylinder 40 under the main shaft 3 drives the U-shaped plate 41 to rise, so that the ceramic grinding roller 42 in the U-shaped plate 41 rises until the ceramic grinding roller 42 contacts the end surface to be ground of the embedded branch nozzle 23. Then, the intermittent pushing component runs to push the ceramic grinding roller 42 to move back and forth to grind the embedded branch nozzle 23. The specific process is: the rotating motor 48 drives the rotating disk 45 to rotate, and then drives the rotating arm 46 and the roller 47 to rotate. The rotating roller 47 hits the step of the transmission block 49 to push As it moves forward, the fourth spring column 51 is compressed, and the support plate 52 and the optical axis 53 are displaced relative to each other. The transmission block 49 is pushed forward to drive the push rod 50 to extend, and the extended push rod 50 pushes the ceramic grinding roller 42 to move. After the roller 47 is separated from the transmission block 49, the fourth spring column 51 releases its elastic potential energy to cause the push rod 50 to retract. It should be noted that the states of the push rods 50 of the two intermittent pushing assemblies are inconsistent. When one push rod 50 is pushed forward, the other push rod 50 is retracted backward. The two push rods 50 are always in contact with the end of the ceramic grinding roller 42.

[0045] After completing the grinding of one group of multiple embedded branch nozzles 23, each stepper motor 8 runs synchronously, driving each disc 4 and the corresponding guide rod 5 to rotate ninety degrees. At this time, the next group of multiple embedded branch nozzles 23 enters the grinding station, and repeats three times until the four groups of embedded branch nozzles 23 have completed the first grinding. When the embedded branch nozzles 23 that have completed grinding follow the disc 4 to rotate until they are aligned with the camera 37, the camera 37 collects images of the grinding conditions of each embedded branch nozzle 23, and transmits the collected images to the background control terminal. Through image recognition, it is determined which workpiece is unqualified and the position of the unqualified workpiece. After completing the first grinding of all embedded branch nozzles 23, the stepper motors 8 of each driving mechanism drive the corresponding rotary feeding assembly to rotate, and then the unqualified workpieces are adjusted to be side by side as much as possible. A group, that is, the guide rod 5 where the unqualified workpiece is located is rotated to the same group, and then this group of workpieces is polished for the second time. After polishing, image collection and recognition are performed again to determine the unqualified workpieces again. Then, the driving mechanism drives each rotary feeding assembly to rotate, and then the unqualified workpieces are adjusted to a group side by side as much as possible, and then this group of workpieces is polished for the third time. Finally, all the workpieces are sent out, that is, the staff pulls out each embedded branch nozzle 23 from the strip groove 55 from the card slot 11. It should be noted that when the embedded branch nozzle 23 is pulled out, the electromagnet 13 moves slightly upward due to inertia, and this slight movement will separate the electromagnet 13 from the conductive connector 15, which will cause the electromagnet 13 to lose its magnetism. Under the action of the first spring column 17, the electromagnet 13 returns to its initial position, which is convenient for the next discharge. In this way, when grinding the end faces of multiple embedded branch nozzles 23 at one time, unqualified workpieces can be adjusted together and re-grinded as a group as possible, thereby saving manpower and material resources. At the same time, the grinding of qualified workpieces can be minimized without the need for early unloading, and the loss of the ceramic grinding roller 42 by the qualified workpieces can be reduced.

[0046] When the stepper motor 8 of the drive mechanism is running, the stepper motor 8 drives the first gear plate 9 and the fourth gear plate 24 to rotate, and the first gear plate 9 drives the second gear plate 7 to rotate synchronously under the transmission action of the first chain 10, thereby driving the disc 4 to rotate. At the same time, the fourth gear plate 24 drives the third gear plate 28 to rotate under the transmission action of the second chain 25, thereby driving the cam 27 to rotate. Under the elastic force of the third spring column 33, the cam 27 moves left and right against the transmission rod 31 during rotation, thereby driving the movable plate 32 to move left and right in the oil chamber 30. When the movable plate 32 moves to the side where the oil outlet 35 is close to the third spring column 33, the oil outlet 35 is exposed, and the lubricating oil drips along the oil outlet 35 onto the first chain 10 below. When the movable plate 32 moves to the side where the oil outlet 35 is away from the third spring column 33, the oil outlet 35 is blocked and the lubricating oil cannot drip, thereby achieving the purpose of intermittently supplying oil to the first chain 10, which can ensure the lubrication of the first chain 10 without causing waste of lubricating oil. It should be noted that the gear ratio between the first and second sprockets 9 and 7 is 1:4. Therefore, when the first sprocket 9 rotates one revolution, the second sprocket 7 rotates ninety degrees, that is, the guide rod 5 rotates ninety degrees. The fourth sprocket 24 is coaxial with the first sprocket 9 and is driven by the same stepper motor 8. Therefore, the fourth sprocket 24 rotates synchronously with the first sprocket 9 and at the same angle. The gear ratio between the fourth sprocket 24 and the third sprocket 28 is 1:1. Therefore, when the fourth sprocket 24 rotates one revolution, the third sprocket 28 also rotates one revolution. Finally, when the third sprocket 28 rotates one revolution, the second sprocket 7 rotates ninety degrees. In addition, every time the guide rod 5 rotates ninety degrees to reach a new workstation, the cam 27 rotates one revolution to complete an intermittent oil discharge. In addition, it should be noted that the intermittent oil supply mechanism matches the number of first chains 10. Each first chain 10 has a corresponding oil outlet 35 directly above it, so that the lubricating oil dripping from the oil outlet 35 can directly fall on the corresponding first chain 10.

[0047] In addition, after a period of time, when the ceramic grinding roller 42 is severely worn and can no longer effectively complete the grinding work, the cylinder 40 under the ceramic grinding roller 42 lowers the U-shaped plate 41, and then the linear motor 39 slowly moves along the linear guide rail 38 to send another ceramic grinding roller 42 to the bottom of the main shaft 3. Immediately afterwards, the cylinder 40 under the main shaft 3 runs to send the U-shaped plate 41 and the new ceramic grinding roller 42 between the two push rods 50.
