Description

Technical Field

[0001] The invention relates to the technical field of three-way pipe fitting processing, in particular to an automatic processing device for the inner wall of a special-shaped pipe fitting. Background Art

[0002] The tee is a pipe connector, also known as a tee joint, which is used at the branch pipe of the main pipe. It is generally in a "T" shape and can achieve the flow effects of one in, one out, one closed, one in, two out, and two in, one out. However, when the tee is produced, its inner wall may be uneven. In this way, in actual use, some debris is likely to remain in the uneven places. Over time, these residues will affect the use of the tee. Chinese patent CN114310518B discloses a Y-type tee cast pipe grinding device, including a base, an upper end face of the base is fixedly connected to a bearing platform through a fixing column, a Y-shaped placement groove for placing the tee is opened on the upper end face of the bearing platform, an L-shaped frame is fixedly connected to the upper end face of the base behind the bearing platform, a sliding seat is fixedly connected to the end face of the T-shaped mounting block on the side away from the arc-shaped guide track, and the sliding seat slides inside A sliding mounting block is connected, and a grinding roller is rotatably connected to the end face of the slider mounting block away from the sliding seat, and a tension spring is fixedly connected between the side end face of the sliding mounting block and the inner groove wall of the slide groove. Although this invention can grind the three pipes of the three-way pipe at the same time, it can only grind the pipe mouth of the tee and cannot grind the inside, which cannot meet the grinding needs. Although Chinese patent application CN117300778A can grind the inside of the three-way pipe, it can only grind the three pipes of the tee one by one, resulting in low efficiency. Moreover, since the three grinding components grind the three pipes of the tee at the same time, if they move to the junction of the tee synchronously, the three grinding components will collide with each other, which will not only fail to achieve the grinding effect, but may also cause damage to the grinding components. Summary of the invention

The present invention drives three grinding components to rotate simultaneously through a toothed disk, and drives the three grinding components to slide along the three pipes of the tee through a transmission frame, thereby grinding the inner wall of the pipe of the tee through the grinding components.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 5 and Figures 8 to 10As shown: an automatic processing device for the inner wall of a special-shaped pipe fitting, comprising a circular workbench 1 and a positioning mechanism 11 arranged on the workbench 1, the workbench 1 is provided with a toothed disc 16, a fixed slide rail 12, a transmission frame 13, a driving mechanism 14, two adjustment arms 15 and three grinding components 2; the toothed disc 16 is rotatably arranged on the workbench 1, and the toothed disc 16 is coaxially arranged with the axis of the workbench 1; the fixed slide rail 12 extends along the radial direction of the workbench 1 and is located inside the toothed disc 16; the two adjustment arms 15 are arranged on both sides of the fixed slide rail 12 in a mirror-symmetrical state, and the two adjustment arms 15 can be relatively moved around the axis of the workbench 1 Rotate, the two adjusting arms 15 are each provided with a first slide rail 151 extending along the length direction thereof; the three grinding assemblies 2 are respectively slidably arranged on the fixed slide rail 12 and the two first slide rails 151, and the three grinding assemblies 2 are all transmission-connected with the gear disk 16; the transmission frame 13 is slidably arranged below the workbench 1 along the axial direction of the workbench 1, and the transmission frame 13 is used to simultaneously drive the three grinding assemblies 2 to slide along the fixed slide rail 12 and the two first slide rails 151; the driving mechanism 14 is rotatably arranged above the workbench 1, and the driving mechanism 14 is used to sequentially drive the three grinding assemblies 2 to slide along the three-way pipe.

[0032] The workpiece is first placed on the positioning mechanism 11 of the workbench 1 so that one of the pipes in the tee is parallel to the fixed slide rail 12. After the tee is positioned by the positioning mechanism 11, the two adjusting arms 15 are adjusted so that the two adjusting arms 15 can be aligned with the other two pipes in the tee, thereby facilitating the subsequent three grinding assemblies 2 to grind the pipes of the tee. The positioning mechanism 11 is relatively common in the prior art and will not be described in detail again. It should be noted that in order to ensure that the grinding rod 211 can better grind the pipe of the tee, the positioning mechanism 11 also has a lifting function to ensure that the three pipes of the tee can be coaxial with the three grinding assemblies 2. At this time, the toothed disc 16 is started to drive the three grinding assemblies 2 to rotate at the same time, and the transmission frame 13 is used to slide along the axial direction of the workbench 1 to drive the three grinding assemblies 2 to slide along the fixed slide rail 12 and the two first slide rails 151, so that the three grinding assemblies 2 slide along the three pipes of the tee respectively, thereby 2 For grinding the inner wall of the tee pipe, since the three grinding assemblies 2 grind the three pipes of the tee at the same time, if they move to the junction of the tee synchronously, the three grinding assemblies 2 will collide with each other, which will not only fail to achieve the grinding effect, but also may cause damage to the grinding assemblies 2. After the three grinding assemblies 2 move to a certain position, the three grinding assemblies 2 are driven in sequence by the driving mechanism 14 to slide along the tee pipe, so that when one of the grinding assemblies 2 grinds the junction of the pipe, the other two grinding assemblies 2 are away from it, so that the three grinding assemblies 2 can grind the junction of the pipe respectively. In this way, not only the grinding efficiency of the tee can be improved, but also the grinding effect of the junction of the tee can be improved. Through the rotation of the two adjusting arms 15, the equipment can achieve grinding for the angle of the tee pipe of 45 degrees or 90 degrees, so that the equipment can achieve grinding operations for special-shaped pipes with different angles, thereby improving the adaptability of the equipment.

[0033] like Figures 2 to 7 As shown: the three grinding components 2 all include a sliding frame 21, a grinding rod 211, a limiting ring 212 and an elastic member 213. The sliding frames 21 of the three grinding components 2 can be slidably arranged on the fixed slide rail 12 and the two first slide rails 151 respectively. The three sliding frames 21 are all transmission-connected to the transmission frame 13. The grinding rod 211 can be slidably arranged on the sliding frame 21, and the axial direction of the grinding rod 211 is parallel to its sliding direction. The limiting ring 212 is fixedly connected to the side of the grinding rod 211 away from the axis of the workbench 1. The elastic member 213 is sleeved on the grinding rod 211, and the two ends of the elastic member 213 are respectively fixedly connected to the limiting ring 212 and the sliding frame 21.

[0034] Through the setting of the sliding frame 21, it is convenient for the grinding assembly 2 to slide on the fixed slide rail 12 and the first slide rail 151. Through the setting of the elastic member 213, the limit ring 212 and the grinding rod 211, the grinding rod 211 can be slidably set on the sliding frame 21, so that after the grinding rod 211 moves to the grinding position in the tee, it is convenient to cooperate with the rotation of the grinding rod 211 to better grind the inner wall of the pipeline by sliding, thereby improving the grinding effect of the tee, and it helps the subsequent driving mechanism 14 to drive the three grinding assemblies 2 in turn to grind the junction of the three-way pipeline, thereby improving the grinding effect of the junction of the tee.

[0035] like Figures 2 to 7 and Fig.10 As shown: a mounting plate 121 is provided on one side of the fixed slide rail 12 and the two adjustment arms 15 close to the toothed disc 16, a rotatable and horizontal transmission shaft 123 is provided on the mounting plate 121, and the transmission shafts 123 on the three mounting plates 121 are parallel to the fixed slide rail 12 and the first slide rail 151, a bevel gear 1232 meshingly connected to the toothed disc 16 is provided on the transmission shaft 123 close to the toothed disc 16, a hexagonal prism 1231 is provided on one side of the transmission shaft 123 close to the polishing rod 211, the interior of the polishing rod 211 is a hollow structure, and the hexagonal prism 1231 is slidably provided in the polishing rod 211.

[0036] By configuring the mounting plate 121, the transmission shaft 123, and the bevel gear 1232, the rotation of the toothed disc 16 can simultaneously drive the rotation of the three bevel gears 1232 meshing with it, and the rotation of the bevel gear 1232 drives the rotation of the transmission shaft 123, thereby driving the rotation of the grinding rod 211 slidably matched with it through the portion of the hexagonal prism 1231 on the transmission shaft 123. By configuring the hexagonal prism 1231 structure, when the sliding frame 21 drives the grinding rod 211 to move, the grinding rod 211 can always maintain the transmission effect with the toothed disc 16, ensuring that the grinding rod 211 can maintain power when sliding, so as to grind the inner wall of the three-way pipe with it.

[0037] like Figures 2 to 7 and Fig.10As shown: each sliding frame 21 is provided with a driving assembly 22 that is transmission-connected to the driving mechanism 14, and the three driving assemblies 22 all include a fixed plate 221, a rotating disk 222, a transmission rod 2222, a connecting column 2221, a sliding ring 223 and a sliding rod 2231. The fixed plate 221 is fixedly connected to the top of the sliding frame 21 in a horizontal state, and the rotating disk 222 is rotatably arranged on the fixed plate 221, and the fixed plate 221 is provided with a second slide rail 2211 extending along its length direction, and the sliding ring 223 is sleeved on the limiting ring 212, and the sliding rod 2231 is fixedly connected to the sliding ring 223, and the sliding rod 2231 is slidably arranged on the second slide rail 2211, and the connecting column 2221 is fixedly connected to the rotating disk 222, and the two ends of the transmission rod 2222 are respectively hinged to the connecting column 2221 and the sliding rod 2231, and the rotating disks 222 of the three driving assemblies 22 are all transmission-connected to the driving mechanism 14.

[0038] The rotation of the driving mechanism 14 drives the turntables 222 on the three driving components 22 to rotate in turn, and the rotation of the turntable 222 drives the connecting column 2221 to rotate around its axis, thereby driving the transmission rod 2222 hinged thereto through the connecting column 2221, driving the sliding rod 2231 hinged thereto through the transmission rod 2222, and driving the sliding ring 223 to move through the sliding rod 2231. Since the sliding rod 2231 can be slidably arranged on the second slide rail 2211, the sliding rod 2231 can only slide along the second slide rail 2211, and the sliding ring 223 The movement of drives the movement of the limit ring 212, and the limit ring 212 pulls the polishing rod 211 to perform reciprocating motion, so that the polishing rod 211 can slide along the axial direction of the pipeline while rotating, thereby improving the polishing effect. In the above manner, when one of the polishing components 2 is polishing the junction of the pipeline, the other two polishing components 2 are away from it, thereby making the three polishing components 2 can respectively polish the junction of the pipeline. In this way, not only the polishing efficiency of the tee can be improved, but also the polishing effect of the junction of the tee can be improved.

[0039] like Figures 1 to 7 , Fig. 9 and Fig.10As shown: the driving mechanism 14 includes a mounting frame 141, a first rotary drive motor 1412, a first rack 1421 and a rotating arm 142. The mounting frame 141 is located above the workbench 1. A rotating shaft 1411 coaxial with the axis of the workbench 1 is provided in the center of the mounting frame 141. The first rotary drive motor 1412 is located at the top of the mounting frame 141. The rotating shaft 1411 is drivingly connected to the output shaft of the first rotary drive motor 1412. The rotating arm 142 is sleeved on the rotating shaft 1411. The rotating arm 142 is an adjustable telescopic structure. The first rack 1421 is fixedly connected to one end of the rotating arm 142 away from the rotating shaft 1411. The turntables 222 of the three driving components 22 are all provided with latching teeth 2223 matching the first rack 1421.

[0040] By starting the first rotary drive motor 1412, the first rotary drive motor 1412 drives the rotary shaft 1411 connected thereto to rotate, the rotary shaft 1411 drives the rotary arm 142 to rotate, the rotary arm 142 drives the first rack 1421 to rotate, and the first rack 1421 drives the turntables 222 on the three drive assemblies 22 to rotate, so that the first rack 1421 can drive the turntable 222 of one of the drive assemblies 22 to grind the junction of the three links when passing through it, and after the first rack 1421 moves away from the turntable 222, the turntable 222 will be elastically moved under the action of the elastic member 213 of the grinding rod 211. The first rack 1421 is preferably arranged in an arc-shaped structure, so that it can better drive the turntable 222 to rotate. The structure of the rotating arm 142 can be retracted, so that the sliding frame 21 drives the grinding rod 211 to move. The first rack 1421 can always maintain a transmission relationship with the turntable 222 by adjusting the length of the rotating arm 142 to ensure the grinding effect.

[0041] like Figures 1 to 5 As shown: a second gear ring 152 and a third gear ring 153 are respectively provided on one end of the two adjusting arms 15 away from the axis of the workbench 1, and the second gear ring 152 and the third gear ring 153 are both incomplete gear rings. A first gear 154 for meshing with the second gear ring 152 and the third gear ring 153 and a second rotary drive motor 155 for driving the first gear 154 to rotate are provided below the workbench 1.

[0042] By starting the second rotary drive motor 155, the second rotary drive motor 155 drives the first gear 154 connected thereto to rotate, and the rotation of the first gear 154 simultaneously drives the second gear ring 152 and the third gear ring 153 meshing therewith, so that the second gear ring 152 and the third gear ring 153 rotate in opposite directions, thereby driving the two adjusting arms 15 to rotate relative to each other. Since most tees are symmetrically structured, this method can more quickly align the grinding assembly 2 with the tee pipe, thereby improving efficiency.

[0043] like Figures 1 to 7 As shown: a fixing assembly 156 is provided on the edge of the adjusting arm 15 close to the workbench 1, and the fixing assembly 156 includes an abutment plate 1561 that can slide along the length direction of the adjusting arm 15 and a linear driver 1562 for driving the abutment plate 1561 to slide.

[0044] After the position of the adjusting arm 15 is adjusted, it is necessary to fix the position of the adjusting arm 15. The linear driver 1562 is started to drive the abutment plate 1561 to slide toward the edge of the workbench 1 along the length direction of the adjusting arm 15, so that the abutment plate 1561 abuts against the edge of the workbench 1, thereby fixing the adjusting arm 15. The linear driver 1562 is preferably a cylinder. An anti-slip groove may be further provided between the abutment plate 1561 and the edge of the workbench 1, thereby further increasing the friction between the two and improving the stability of the fixation of the adjusting arm 15.

[0045] like Figures 1 to 3 As shown: a fourth gear ring 161 fixedly connected to the gear disc 16 is also provided at the bottom thereof, a second gear 162 meshingly connected to the fourth gear ring 161 is provided beside the fourth gear ring 161 , and a third rotary drive motor 163 for driving the second gear 162 is provided below the workbench 1 .

[0046] By starting the third rotary drive motor 163, the third rotary drive motor 163 drives the second gear 162 connected thereto to rotate, and the rotation of the second gear 162 drives the fourth gear ring 161 to rotate, and the rotation of the fourth gear ring 161 drives the gear plate 16 to rotate, and the rotation of the gear plate 16 drives the three grinding assemblies 2 to rotate, thereby facilitating the grinding assembly 2 to grind the tee.

[0047] like Figures 2 to 4 and Figure 8As shown: a rotatable vertical screw rod 131 is arranged at the bottom of the workbench 1, three guide rods 132 which are parallel to the axis of the screw rod 131 are arranged on the circumferential side of the screw rod 131, a transmission frame 13 is sleeved on the screw rod 131 and the three guide rods 132, the transmission frame 13 is threadedly matched with the screw rod 131, the transmission frame 13 is slidingly matched with the three guide rods 132, a fourth rotary drive motor 1311 which can drive the screw rod 131 to rotate is arranged at the bottom of the workbench 1, a slider 133 which is rotatably connected to the transmission frame 13 is arranged on the transmission frame 13, a connecting rod 1331 is arranged between the slider 133 and the bottom of the sliding frame 21, and the two ends of the connecting rod 1331 are respectively hinged to the slider 133 and the bottom of the sliding frame 21.

[0048] By starting the fourth rotary drive motor 1311, the fourth rotary drive motor 1311 drives the rotation of the screw rod 131 connected thereto, and the rotation of the screw rod 131 drives the movement of the transmission frame 13 threadedly matched therewith, so that the transmission frame 13 slides along the axial direction of the three guide rods 132, and the sliding of the transmission frame 13 drives the movement of the slider 133, and the movement of the slider 133 drives the movement of the connecting rod 1331, and the movement of the connecting rod 1331 drives the movement of the sliding frame 21. When the transmission frame 13 moves to the top of the screw rod 131, the three sliding frames 21 move away from each other, and vice versa. Since the slider 133 is rotatably connected to the transmission frame 13, the two adjusting arms 15 are at any angle, and the transmission frame 13 can always drive the sliding frame 21 on the adjusting arm 15 to move. In this way, the grinding assembly 2 on the sliding frame 21 can be driven to enter the inner walls of the three pipes of the tee at the same time, thereby improving the grinding efficiency.

[0049] like Figures 3 to 7 and Fig.10 As shown: the mounting plate 121 is provided with a limiting block 122 which matches the fixing plate 221 .

[0050] Since the fixed plate 221 is fixedly connected to the sliding frame 21, and a driving assembly 22 is provided on the fixed plate 221, if the fixed plate 221 is not supported, it is easy to be damaged. Through the setting of the limit block 122, it can support the fixed plate 221. At the same time, when the sliding frame 21 drives the fixed plate 221 to move, the fixed plate 221 can be better limited by the limit block 122, thereby improving the stability of the sliding frame 21 and extending the service life of the fixed plate 221.

[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
