Description

Technical Field

[0001] The present invention is a tapping device for pipe fittings joints, belonging to the field of tapping devices. Background Art

[0002] Tapping is a common metal processing technique used to create internal threads on workpieces. By machining internal threads in the pipe joints of pipe fittings joints, it is convenient to install the pipe fittings joints at one end of the pipeline by means of threaded connection. To improve the tapping efficiency, multiple fixtures are often used to limit the position of the pipe fittings joints, and then a driving member is used to drive multiple motors with tapping heads to synchronously descend, so that the rotating tapping heads simultaneously process the internal threads of the pipe joints in multiple pipe fittings joints. During the tapping process of multiple tapping heads on multiple pipe joints respectively, if a certain tapping head malfunctions, it is necessary to make multiple tapping heads stop working synchronously. At this time, the non-faulty tapping heads will get stuck in the corresponding pipe joints, and the subsequent processing is rather troublesome. Summary of the Invention

A plurality of motors are evenly installed on the lower surface of the cross beam. A tapping head is installed at the output end of the motor. A base is provided directly below each of the plurality of motors. The base is in sliding contact with the carrier plate. A V-shaped seat for restricting the position of the spherical head is installed at the lower part of the front surface of the base.

A rotary cylinder is installed on one side surface of the base. A pressing arm for pressing the pipe joint is installed at the movable end of the rotary cylinder. A soft rubber head is installed at the end of the pressing arm away from the rotary cylinder. A driving member for controlling the downward movement of the base is installed on the side of the carrier plate facing away from the base.

[0005] Specifically, the driving member includes a cross plate. The cross plate is installed on the side of the carrier plate facing away from the base through a positioning member. A plurality of vertically arranged air cylinders are evenly installed on the lower surface of the cross plate. The movable ends of the plurality of vertically arranged air cylinders are all installed with connecting seats. The connecting seats are of L-shaped structure. The vertical part of the connecting seat is in sliding contact with the carrier plate. A vertically arranged long circular hole is formed in the area of the carrier plate covered by the base. Two connecting columns are inserted into the long circular hole. The two ends of the connecting columns are respectively connected and fixed to the connecting seat and the base.

[0006] Specifically, the positioning member includes a positioning plate. A positioning plate arranged parallel to the horizontal plate is provided on the upper side of the horizontal plate. The positioning plate is in sliding contact with the carrier plate. The positioning plate is connected and fixed to the carrier plate through a connecting member. Two sets of adjusting members are installed between the positioning plate and the horizontal plate.

[0007] Specifically, the connecting member includes an L-shaped plate. A plurality of L-shaped plates are slidably installed on the upper surface of the positioning plate. A perforation is provided at the lower position of one side surface of the L-shaped plate. A transverse screw is inserted into the channel formed by the plurality of perforations. Both ends of the transverse screw are connected to the positioning plate. First nuts are provided on both sides of the perforation along the length direction of the transverse screw. The first nuts are threadedly connected to the transverse screw. A plurality of fixing holes are evenly provided on the surface of the L-shaped plate facing the carrier plate. Connecting screws are inserted into the fixing holes. The connecting screws are threadedly connected to the carrier plate.

[0008] Specifically, two supporting ears are symmetrically connected and fixed to the upper surface of the positioning plate. Through holes are provided on the opposite surfaces of the two supporting ears. The end of the transverse screw penetrates through the through hole. Second nuts are provided on both sides of the through hole along the transverse screw. The second nuts are threadedly connected to the transverse screw.

[0009] Specifically, the adjusting member includes a vertical screw. Vertical holes are provided at both ends of the positioning plate. Vertical screws are inserted into the two vertical holes. The lower end of the vertical screw is connected and fixed to the horizontal plate. Limiting nuts are provided on both sides of the vertical hole along the length direction of the vertical screw.

[0010] Specifically, two straight threaded cylinders are symmetrically installed on the upper surface of the horizontal plate. The lower end of the vertical screw is threadedly connected to the straight threaded cylinder.

[0011] Specifically, a chassis is installed at the bottom of the housing. Adjusting feet are installed at the four corners of the bottom of the chassis.

[0012] Advantages of the present invention:

[0013] 1. When a certain motor fails and cannot drive the corresponding tapping head to rotate normally, control the corresponding vertical cylinder to extend and control the corresponding rotary cylinder to work, so that the pressing arm is separated from the corresponding pipe joint. Thus, the vertical cylinder drives the connecting column to move downward along the long circular hole through the connecting seat. At this time, the base moves downward, and the pipe joint formed by the spherical head and the pipe joint is separated from the fixture structure formed by the base and the V-shaped seat. Other motors without failures can continue to work for tapping operations, avoiding the tapping heads without failures getting stuck in the corresponding pipe joints when multiple motors stop working simultaneously, and reducing the workload of separating the tapping heads from the pipe joints.

[0014] 2. Adjust the spacing between multiple L-shaped plates along the horizontal screw as needed. At this time, the relative position between the L-shaped plate and the carrier plate changes. After the L-shaped plate moves to the desired position, use the first nut to limit the relative position between the L-shaped plate and the horizontal screw, so as to adjust the relative position between the L-shaped plate and the carrier plate as needed. Connect the L-shaped plate and the carrier plate with connecting screws, thereby increasing the connection range between the vertical cylinder and the carrier plate and improving the stability of the structure.

[0015] 3. Pass the end of the horizontal screw through the through hole on the support ear, and then use the second nut to limit the relative position between the horizontal screw and the support ear to complete the assembly of the horizontal screw and the positioning plate. On the one hand, it is convenient to increase the number of L-shaped plates on the horizontal screw, and on the other hand, it realizes the convenient disassembly and assembly of the horizontal screw and the positioning plate.

[0016] 4. Pass the two vertical screws on the cross plate through the two vertical holes on the positioning plate respectively. According to the installation height of the positioning plate, adjust the position of the vertical screw along the vertical hole. At this time, the spacing between the cross plate and the positioning plate changes, that is, the spacing between the positioning plate and the vertical cylinder changes. Use the limit nut to limit the relative position between the vertical screw and the positioning plate to complete the limitation of the relative position between the positioning plate and the vertical cylinder, so as to adjust the installation position of the positioning plate on the carrier plate without changing the layout position of the vertical cylinder, and at the same time facilitate adjusting the height of the base and the vertical cylinder according to the length of the pipe joint to meet the needs of tapping different pipe joints. And because the height of the base is adjustable, that is, the spacing between the base and the tapping head in the initial state is adjustable. When the base moves downward, when the hydraulic cylinder is fully extended, the depth of the tapping head moving into the pipe joint becomes shorter, and vice versa, the depth of the tapping head moving into the pipe joint increases, so as to achieve the purpose of adjusting the tapping depth in the pipe joint as needed.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figure 1 , the present invention provides a technical solution: a pipe fitting tapping device, including a housing 1, an underframe 7 is installed at the bottom of the housing 1, adjusting feet 8 are installed at the four corners of the bottom of the underframe 7, a rectangular opening is provided on the front surface of the housing 1, a vertically arranged carrier plate 11 is installed on one side of the housing 1 close to the rectangular opening, a vertically arranged hydraulic cylinder 2 is installed on one side of the top of the housing 1 close to the rectangular opening, the movable end of the hydraulic cylinder 2 extends into the housing 1 and is installed with a cross beam in sliding contact with the carrier plate 11, a plurality of motors 3 are evenly installed on the lower surface of the cross beam, the output end of the motor 3 is installed with a tapping head 4, during the telescopic process of the hydraulic cylinder 2, the hydraulic cylinder 2 drives the plurality of motors 3 to move up or down synchronously through the cross beam.

[0027] Refer to Figure 1 and Figure 4, a base 6 is provided directly below each of the multiple motors 3. The base 6 is in sliding contact with the carrier plate 11. At the lower position on the front surface of the base 6, a V-shaped seat 5 for restricting the position of the spherical head 27 is installed. On the upper side of the V-shaped seat 5, two clamping seats 26 for restricting the position of the pipe joint 25 are provided. The clamping seats 26 are connected and fixed to the base 6 by screws. A rotary cylinder 23 is installed on one side surface of the base 6. A pressing arm 24 for pressing the pipe joint 25 is installed at the movable end of the rotary cylinder 23. A soft rubber head is installed at the end of the pressing arm 24 away from the rotary cylinder 23. Place the spherical head 27 in the V-shaped seat 5 and make the pipe joint 25 located between the two clamping seats 26. Then control the rotary cylinder 23 to rotate so that the soft rubber head on the pressing arm 24 comes into contact with the pipe joint 25, realizing the restriction of the position of the pipe joint formed by the pipe joint 25 and the spherical head 27.

[0028] Refer to Figures 1-5 , on the surface of the carrier plate 11 facing away from the base 6, a cross plate 13 is installed through a positioning member. A plurality of vertical cylinders 12 are evenly installed on the lower surface of the cross plate 13. A connecting seat 9 is installed at the movable end of each of the plurality of vertical cylinders 12. The connecting seat 9 is of an L-shaped structure. The vertical part of the connecting seat 9 is in sliding contact with the carrier plate 11. A vertically arranged long circular hole 10 is opened in the area of the carrier plate 11 covered by the base 6. Two connecting columns 22 are inserted into the long circular hole 10. The two ends of the connecting column 22 are respectively connected and fixed to the connecting seat 9 and the base 6. When a certain motor 3 fails and cannot drive the corresponding tapping head 4 to rotate normally, control the corresponding vertical cylinder 12 to extend and control the corresponding rotary cylinder 23 to work so that the pressing arm 24 is separated from the corresponding pipe joint 25. Thus, the vertical cylinder 12 drives the connecting column 22 to move downward along the long circular hole 10 through the connecting seat 9. At this time, the base 6 moves downward, and the pipe joint formed by the spherical head 27 and the pipe joint 25 is separated from the fixture structure formed by the base 6 and the V-shaped seat 5. The other motors 3 without failures can continue to work for tapping operations, avoiding the tapping heads 4 without failures being stuck in the corresponding pipe joints 25 when multiple motors 3 stop working simultaneously, and reducing the workload of separating the tapping heads 4 from the pipe joints 25.

[0029] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6, a positioning plate 16 parallel to the horizontal plate 13 is provided on the upper side of the horizontal plate 13. The positioning plate 16 is in sliding contact with the carrier plate 11. A plurality of L-shaped plates 21 are slidably mounted on the upper surface of the positioning plate 16. A perforation 32 is formed at the lower position of one side surface of the L-shaped plate 21. A transverse screw 18 is inserted into the channel formed by the plurality of perforations 32. Both ends of the transverse screw 18 are connected to the positioning plate 16. First nuts 20 are provided on both sides of the perforation 32 along the length direction of the transverse screw 18. The first nuts 20 are threadedly connected to the transverse screw 18. A plurality of fixing holes 28 are evenly formed on the surface of the L-shaped plate 21 facing the carrier plate 11. A connecting screw 19 is inserted into the fixing hole 28. The connecting screw 19 is threadedly connected to the carrier plate 11. According to the need, the distance between the plurality of L-shaped plates 21 is adjusted along the transverse screw 18. At this time, the relative position between the L-shaped plate 21 and the carrier plate 11 is changed. When the L-shaped plate 21 moves to the required position, the relative position between the L-shaped plate 21 and the transverse screw 18 is restricted by the first nut 20, so as to realize the adjustment of the relative position between the L-shaped plate 21 and the carrier plate 11 according to the need. The L-shaped plate 21 and the carrier plate 11 are connected by the connecting screw 19, thereby increasing the connection range between the vertical cylinder 12 and the carrier plate 11 and improving the stability of the structure.

[0030] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , two support ears 31 are symmetrically connected and fixed to the upper surface of the positioning plate 16. Through holes 30 are formed on the opposite surfaces of the two support ears 31. The end of the transverse screw 18 penetrates through the through hole 30. Second nuts 29 are provided on both sides of the through hole 30 along the transverse screw 18. The second nuts 29 are threadedly connected to the transverse screw 18, so that the end of the transverse screw 18 penetrates through the through hole 30 on the support ear 31, and then the relative position between the transverse screw 18 and the support ear 31 is restricted by the second nut 29, completing the assembly of the transverse screw 18 and the positioning plate 16. On the one hand, it is convenient to increase the number of L-shaped plates 21 on the transverse screw 18, and on the other hand, the convenient disassembly and assembly of the transverse screw 18 and the positioning plate 16 are realized.

[0031] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6, vertical holes 33 are provided at both ends of the positioning plate 16, and vertical screw rods 15 are inserted into both of the two vertical holes 33. The lower end of the vertical screw rod 15 is fixedly connected to the cross plate 13. Among them, two straight thread cylinders 14 are symmetrically installed on the upper surface of the cross plate 13, so that the lower end of the vertical screw rod 15 is threadedly connected in the straight thread cylinder 14, which is convenient for the disassembly and assembly of the vertical screw rod 15 and the cross plate 13. Limit nuts 17 are provided on both sides of the vertical hole 33 along the length direction of the vertical screw rod 15. The limit nuts 17 are threadedly connected to the vertical screw rod 15, so that the two vertical screw rods 15 on the cross plate 13 respectively penetrate through the two vertical holes 33 on the positioning plate 16. According to the installation height of the positioning plate 16, the position of the vertical screw rod 15 is adjusted along the vertical hole 33. At this time, the distance between the cross plate 13 and the positioning plate 16 changes, that is, the distance between the positioning plate 16 and the vertical cylinder 12 changes. The relative position of the vertical screw rod 15 and the positioning plate 16 is restricted by the limit nut 17, and the relative position of the positioning plate 16 and the vertical cylinder 12 is restricted, realizing the adjustment of the installation position of the positioning plate 16 on the carrier plate 11 without changing the layout position of the vertical cylinder 12. At the same time, it is convenient to adjust the heights of the base 6 and the vertical cylinder 12 according to the length of the pipe joint 25 to meet the needs of tapping different pipe joints 25. And because the height of the base 6 can be adjusted, that is, the distance between the base 6 and the tapping head 4 in the initial state can be adjusted. When the base 6 moves downward, when the hydraulic cylinder 2 is fully extended, the depth of the tapping head 4 moving into the pipe joint 25 becomes shorter. On the contrary, the depth of the tapping head 4 moving into the pipe joint 25 increases, realizing the purpose of adjusting the tapping depth in the pipe joint 25 as needed.
