Description

Technical Field

[0001] The present invention relates to the technical field of rotary joint production, and more specifically, to a punching device for rotary joint production. Background Art

[0002] A rotary joint, also known as a rotary seal or swivel joint, is a special connection device that allows fluid (such as water, oil, steam, etc.) or gas to be transmitted between two relatively rotating parts while maintaining good sealing performance. Rotary joints are widely used in many industries, including machinery manufacturing, chemical industry, oil extraction, food processing, etc.

[0003] The outer shell of the rotary joint is usually made of metal material. It is the basic frame of the entire rotary joint, responsible for protecting the internal components and providing necessary support. In order to allow the medium to enter or flow out of the rotary joint from the side, radial side holes are usually opened on the outer periphery of the outer shell. The radial side holes are perpendicular to and connected to the axial through hole in the center. These radial side holes facilitate changing the flow direction of the medium during rotation. One end of the outer shell is also rotatably connected to a water outlet pipe.

[0004] In order to facilitate the rotation adjustment, the existing technology adopts the method of placing the rotary joint horizontally, fixing the water outlet pipe with a clamp at one end, and adjusting the punching position by driving the outer shell to rotate with a motor at the other end. When a plurality of radial side holes are opened on the outer periphery of the rotary joint outer shell, since the radial side holes are connected with the axial through holes, the waste chips generated by the punching will accumulate on the core shaft inside the outer shell. The core shaft is an important component for providing rotation. The accumulation of waste chips will hinder the subsequent rotation adjustment. In severe cases, the position after the rotation adjustment will be inaccurate.

[0005] The prior art uses blowing or flushing from one end to clean the waste chips at the core shaft. In order to avoid the cleaned waste chips from being discharged randomly, the prior art sets a collection mechanism at the other end. As the number of radial side holes that have been opened increases, some of the waste chips will be discharged from the opened radial side holes, causing pollution to the processing site. Summary of the invention

[0006] The present invention provides a punching device for producing rotary joints, and aims to solve the problem that when the existing punching device for producing rotary joints is cleaned, as the number of radial side holes that have been punched increases, some waste chips will be discharged from the punched radial side holes, causing contamination of the processing site.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual Figures 1 to 12A punching device for producing a rotary joint includes a processing box 1, a drilling machine 2 is installed on the processing box 1, a processing table 3 is installed inside the processing box 1, when a joint shell 36 is placed horizontally on the processing table 3, the outer periphery of the joint shell 36 is processed into a radial side hole 362 by the drilling machine 2, and a blocking mechanism 6 is passed through the radial side hole 362, and a partition 7 is provided at the output end of the blocking mechanism 6, and the partition 7 is movably arranged inside the joint shell 36; the blocking mechanism 6 includes a blocking cylinder 61, one end of the blocking cylinder 61 A shaft seat 62 is fixedly provided, and both sides of the partition 7 are rotatably connected to the shaft seat 62. An operating rod 63 is rotatably connected to one end of the partition 7, and the operating rod 63 passes through the interior of the blocking tube 61; air bags 71 are provided on both sides of the partition 7, and an air cylinder 65 is fixedly provided at one end of the blocking tube 61. One end of the air cylinder 65 is connected to an air pipe 651, and the interior of the air cylinder 65 is connected to the partition 7. When air is inflated into the interior of the air cylinder 65 through the air pipe 651, the air bag 71 expands and blocks one end of the core shaft 361.

[0037] It should be noted that one end of the blocking cylinder 61 corresponding to the shaft seat 62 is open, which is convenient for the connecting end of the partition 7 and the operating rod 63 to enter and exit. The shaft seat 62 is two sets of opposite vertical plates, and a relatively vertical rotating shaft is installed on the vertical plate. The vertical plate is connected to the outer side of the partition 7 through the rotating shaft to support the rotation of the partition 7. When the partition 7 rotates, the rotating shaft is the center. The end of the operating rod 63 away from the partition 7 is located outside the blocking cylinder 61, and the moving trajectory of the operating rod 63 inside the blocking cylinder 61 is from obliquely downward to obliquely upward, or a group of connecting rods are arranged between the partition 7 and the operating rod 63, and the two ends of the connecting rod are respectively rotatably connected to the partition 7 and the operating rod 63, so that the operating rod 63 can drive the partition 7 to flip by moving vertically, and the end of the air pipe 651 away from the air cylinder 65 is connected to an external air pump.

[0038] In this embodiment, the implementation scenario is specifically as follows: when processing the second radial side hole 362, the partition 7 is parallel to the plugging tube 61, and the sealing mechanism 6 is placed inside the first radial side hole 362. By pulling the operating rod 63 toward the outside of the plugging tube 61, the partition 7 is flipped to one side 15-90 degrees, and the air is inflated into the air cylinder 65 through an external air pump and an air pipe 651, and then the air is inflated into the partition 7 to expand the airbag 71. At this time, the inflated airbag 71 blocks the core shaft 361 inside the joint housing 36. When cleaning, the opened radial side hole 362 can be sealed by the sealing mechanism 6 to prevent the cleaned waste from being discharged from the opened radial side hole 362 and causing the processing site to be contaminated.

[0039] Furthermore, a handle 631 is fixedly provided at one end of the operating rod 63 away from the partition 7, an elastic block 72 is fixedly provided at one end of the partition 7 away from the air cylinder 65, an air inlet hole 73 is opened at one end of the partition 7 close to the air cylinder 65, the air inlet hole 73 is connected to the air cylinder 65 by a hose, and the elastic block 72 is made of rubber or foam material.

[0040] It should be noted that by pulling the operating rod 63 through the handle 631, the hose between the air inlet 73 and the air cylinder 65 is displaced accordingly, and the elastic block 72 is convenient to contact the inner wall of the joint shell 36 and deform, thereby preventing the partition 7 from being blocked when flipping, and the air inlet 73 is connected to the airbag 71.

[0041] Furthermore, a blocking block 64 is fixedly provided inside the end of the blocking tube 61 away from the shaft seat 62, a slot 611 is opened inside the blocking block 64, and both ends of the slot 611 are open, and blocking pieces 632 are fixedly provided on both sides of the handle 631, and the blocking pieces 632 are movably arranged inside the slot 611.

[0042] It should be noted that the slot 611 is a three-dimensional "cross-shaped" component, including a transverse slot and a vertical slot. The two ends of the transverse slot are open and the vertical height is less than the height of the plugging tube 61. The vertical slot runs through the inside of the plugging tube 61 and is open at both ends, providing space for the operating rod 63 to drive the blocking piece 632 to move diagonally upward or downward. The blocking piece 632 can pass through the two transverse ends of the slot 611 and always separate the upper and lower halves of the vertical slot to prevent waste chips from leaking out of the vertical slot. When cleaning waste chips, the plugging tube 61 is tilted to clear the waste chips from the transverse slot. The slot 611 is a long slot type, which can adapt to the transverse movement trajectory of the operating rod 63, and is used to limit the movement of the operating rod 63 to prevent the operating rod 63 from driving the partition 7 to over-flip and get stuck.

[0043] Furthermore, a sealing ring 66 is sleeved on the outer periphery of the plugging tube 61 , and the sealing ring 66 is movably disposed inside the radial side hole 362 . A sealing gasket 67 is sleeved on the outer periphery of the sealing ring 66 , and the sealing gasket 67 is located outside the radial side hole 362 .

[0044] It should be noted that the sealing ring 66 is in the shape of a long cylinder. The sealing ring 66 follows the plugging tube 61 to slide inside the radial side hole 362. The sealing gasket 67 slides along the outside of the sealing ring 66 and can be sealed from the outside of the radial side hole 362. When the partition 7 is flipped to an angle of about 30 degrees, a space is left between one end of the partition 7 and the inner wall of the joint shell 36. By pushing the plugging tube 61 into the joint shell 36, the space is reduced, which can better play a blocking role. The sealing ring 66 is convenient for playing a blocking role when the plugging tube 61 is pushed into the joint shell 36.

[0045] Furthermore, a processing chamber 11 is opened inside the processing box 1, and the drilling machine 2 is installed inside the processing chamber 11.

An adjustment screen 16 is installed on one side of the processing box 1, and the adjustment screen 16 is used to adjust the working parameters of the drilling machine 2.

[0046] It should be noted that the processing chamber 11 is used to place the processing table 3, and a chamber door is hinged on the processing chamber 11. The chamber door can be closed during processing to prevent debris from splashing. The adjustment screen 16 is used to adjust the working parameters of the drilling machine 2. The drilling machine 2 adopts the drilling equipment of the prior art, and its working circuit and working mode are common technologies for people in this field.

[0047] Furthermore, a support frame 13 is installed at the bottom of the processing box 1, a cleaning box 14 is installed on the support frame 13, and the cleaning box 14 is connected to one end of the joint shell 36 through a pipe, and a power box 15 is installed on one side of the support frame 13, and the power box 15 is used to provide power to the cleaning box 14.

[0049] Furthermore, a placement seat 31 is installed on the processing table 3, and the joint shell 36 is movably placed on the placement seat 31. An adjusting cylinder 2 38 is installed at the bottom of the processing table 3. The output end of the adjusting cylinder 2 38 is connected to the adjusting arm 33, and a clamping claw 34 is installed on the adjusting arm 33. The adjusting cylinder 2 38 pushes the adjusting arm 33 to rotate so that the clamping claw 34 is close to the joint shell 36. An opening 32 is opened at the position of the processing table 3 corresponding to the adjusting arm 33.

[0050] It should be noted that the placement seat 31 is a prior art, and its specifications are designed according to the size and shape of the joint shell 36. The side of the placement seat 31 is L-shaped, so that one end and both sides of the joint shell 36 are unobstructed. One end of the adjusting arm 33 is rotatably connected to the inner wall of the opening 32 through a support seat. The support seat has the same function as the shaft seat 62, and is used to support the adjusting arm 33 to flip. The adjusting cylinder 38 pushes one end of the adjusting arm 33 to flip it, so that the clamping claw 34 abuts against one side of the joint shell 36.

[0051] Furthermore, a control console 12 is installed at the front end of the processing box 1, and a positioning cylinder 1 4 and a positioning cylinder 2 41 are installed on the processing table 3, and the positioning cylinder 1 4 is located above the positioning cylinder 2 41, and the output ends of the positioning cylinder 1 4 and the positioning cylinder 2 41 are both provided with a positioning column 42, and the positioning column 42 is located on the side of the joint housing 36 away from the clamp 34.

[0052] It should be noted that the control console 12 is used to install the controllers of the positioning cylinder 1 4 and the positioning cylinder 2 41. The positioning cylinder 2 41 and the clamping claw 34 are arranged on both sides of the joint shell 36 opposite to each other. The positioning cylinder 1 4 is arranged on the upper inclined part of the joint shell 36 to form a three-claw positioning, so that the joint shell 36 is firmly positioned.

[0053] Furthermore, a driving motor 5 is installed at one end of the placement seat 31, and the output end of the driving motor 5 is detachably connected to one end of the joint housing 36. A control console 2 35 is installed on the processing table 3, and the control console 2 35 is used to control the switch of the driving motor 5.

[0054] It should be noted that a controller for the drive motor 5 is installed on the console 2 35, and the drive motor 5 is connected to one end of the joint housing 36 through a movable connecting piece, and the movable connecting piece can meet the following conditions: after the joint housing 36 moves horizontally, it can automatically or manually detach from or dock with the output end of the drive motor 5, such as a manual flange or an automatically expanding clamp 34, which can drive the joint housing 36 to rotate after docking.

[0056] It should be noted that the adjusting cylinder 37 drives the placement seat 31 to move axially along the joint shell 36 to facilitate position adjustment. The adjusting cylinder 37 drives the placement seat 31 away from the drive motor 5, and the joint shell 36 can be placed or removed, and drives the placement seat 31 to approach the drive motor 5 and dock with it, so that subsequent drilling processing can be carried out.
