Description

Technical Field

[0001] This application relates to the field of threading machine technology, and in particular to a threading machine for low-voltage engineering. Background Technology

[0002] Low-voltage electrical engineering is increasingly widely used in modern buildings, communications, security and other fields. Low-voltage electrical engineering mainly involves low-voltage electronic systems, such as communications, computer networks, security systems, and building automation. The normal operation and efficient connection of these systems are crucial to ensuring the functionality of the entire building or system. In low-voltage electrical engineering, threading machines are an important tool and equipment used to precisely process threads on materials such as cables and pipes to achieve stable connections between devices.

[0003] However, existing threading machines only clamp and fix the outside of the pipe to be threaded, without supporting the inner wall of the pipe. Since the pipes used in low-voltage engineering have thin walls, they are easily crushed by the die during the threading process, which affects the subsequent connection of the pipe and reduces the effectiveness of the device. Therefore, a threading machine for low-voltage engineering is proposed. Utility Model Content

[0004] To address the issue of insufficient support for the inner wall of pipes during threading, this application provides a threading machine for low-voltage electrical engineering.

[0005] The threading machine for low-voltage engineering provided in this application adopts the following technical solution:

[0006] A threading machine for low-voltage electrical engineering includes a base. A drive motor is mounted on the surface of the base. A rotating housing is fixedly connected to the output end of the drive motor. A connecting rod arranged at equal intervals in a circle is fixedly connected to the side of the rotating housing away from the output end of the drive motor. A threading disc is fixedly connected to the end of the connecting rod away from the rotating housing. An adjusting block arranged at equal intervals in a circle is slidably connected to the surface of the threading disc. A die is fixedly installed inside the adjusting block. A connecting pipe communicating with the rotating housing is fixedly connected to the surface of the rotating housing. The end of the connecting pipe near the rotating housing is threaded. The end of the connecting pipe away from the rotating housing is threaded. The connecting tube is fixedly connected to a second fixed ring and a first fixed ring. An inner support plate arranged equidistantly in a circle is provided on the outside of the connecting tube. A movable ring is slidably connected to the surface of the connecting tube. A third connecting rod is rotatably connected between the inner support plate and the movable ring. A second connecting rod and a first connecting rod are rotatably connected between the inner support plate and the second and first fixed rings. The third connecting rod, the second connecting rod and the first connecting rod are all in an inclined state. A driving bolt is threadedly connected to the surface of the connecting tube. An installation rod is fixedly connected to the side of the driving bolt near the movable ring. The end of the installation rod away from the driving bolt is rotatably connected to the surface of the movable ring.

[0007] By adopting the above technical solution, the inner wall of the pipe to be threaded can be supported by the internal support plate, thereby avoiding the pipe being crushed during the threading process and improving the threading quality of the pipe.

[0008] Preferably, a return spring is fixedly connected between the adjusting block and the threading disc, and a screw-in disc with a conical inner wall is threadedly connected to the surface of the threading disc. The surface of the screw-in disc is provided with through grooves arranged circumferentially at equal intervals.

[0009] By adopting the above technical solution, the protruding length of the die can be adjusted using the rotary disc, thereby enabling the die to process pipes of different diameters and thus improving the applicability of the device.

[0010] Preferably, the surface of the inner support plate is provided with a hidden groove, and the inner wall of the hidden groove is fixedly connected with nozzles arranged at equal intervals.

[0011] By adopting the above technical solution and utilizing the concealed groove, the nozzle can be hidden, avoiding wear between the nozzle and the inner wall of the pipe, which could lead to nozzle damage and thus improve the service life of the device.

[0012] Preferably, a second corrugated pipe is fixedly connected between the connecting pipe and the inner support plate, and the two ends of the second corrugated pipe are respectively connected to the inner support plate and the connecting pipe.

[0013] By adopting the above technical solution and utilizing the second corrugated pipe, the second corrugated pipe can expand and contract accordingly after the inner support plate moves, so that the coolant can always be delivered into the inner support plate, ensuring the smooth operation of the device.

[0014] Preferably, a support plate is fixedly connected to the inner wall of the base, a liquid storage tank is fixedly connected to the surface of the support plate, a water pump is installed inside the liquid storage tank, and a drain pipe that penetrates the surface of the liquid storage tank is fixedly connected inside the liquid storage tank. One end of the drain pipe located inside the liquid storage tank is fixedly connected to the outlet end of the water pump.

[0015] By adopting the above technical solution and using a water pump, the coolant in the storage tank can be transported to the outside, thereby cooling the pipeline and preventing the pipeline from being in a high-temperature state, which would affect the pipeline processing quality.

[0016] Preferably, the inner wall of the rotating shell is rotatably connected to an annular cover, and an injection pipe penetrating the surface of the annular cover is fixedly connected inside the annular cover. A first corrugated pipe is fixedly connected between the injection pipe and the drainage pipe.

[0017] By adopting the above technical solution, the rotating shell can be sealed using a ring cover.

[0018] Preferably, a mounting shell is fixedly connected to the surface of the base, and two clamping blocks are slidably connected to the inner wall of the mounting shell. The opposite sides of the two clamping blocks are V-shaped, and rubber pads are provided on the opposite sides of the two clamping blocks.

[0019] By adopting the above technical solution, two clamping blocks are used to fix the pipe to be threaded, thereby ensuring the stability of the pipe during threading.

[0020] Preferably, the mounting housing is rotatably connected to a bidirectional threaded rod, which passes through the surfaces of the two clamping blocks and is threadedly connected to the interior of the two clamping blocks. The threads at both ends of the bidirectional threaded rod are respectively matched with the threads inside the two clamping blocks.

[0021] By adopting the above technical solution, the two clamping blocks can be driven to move relative to each other using a bidirectional threaded rod, thereby achieving clamping and fixing of the pipeline.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The internal support plate can support the inner wall of the pipe to be threaded, thus preventing the pipe from being crushed during threading and affecting its subsequent use. This improves the effectiveness of the device and is worth promoting.

[0024] 2. The nozzle can spray coolant onto the inner wall of the pipe, thereby cooling the pipe and preventing the pipe from overheating during threading, which would reduce the quality of pipe processing and further improve the effectiveness of the device. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] This application discloses a threading machine for low-voltage electrical engineering.

[0037] Reference Figures 1-6 A threading machine for low-voltage engineering includes a base 1. A drive motor 6 is provided on the surface of the base 1 to provide power for the operation of the device. A moving mechanism is provided between the drive motor 6 and the base 1 to drive the drive motor 6 to move on the base 1, so that the drive motor 6 can move back and forth on the base 1. The movement of the drive motor 6 can be driven by electric or manual means, which is a conventional technical means in the field and will not be discussed here.

[0038] A rotating housing 21, serving as a coolant delivery channel, is fixedly connected to the output end of the drive motor 6. An annular cover 23, which seals the rotating housing 21, is rotatably connected to the inner wall of the rotating housing 21. A connecting rod 22, arranged equidistantly in a circle, is fixedly connected to the side of the rotating housing 21 away from the output end of the drive motor 6, connecting the rotating housing 21 to the threading disc 14. A threading disc 14, providing an installation position for the die 13, is fixedly connected to the end of the connecting rod 22 away from the rotating housing 21. Adjusting blocks 12, arranged equidistantly in a circle, are slidably connected to the surface of the threading disc 14, providing installation space for the die 13. A die for threading pipes is fixedly installed inside the adjusting block 12. 13. The die 13 can be connected to the adjusting block 12 by bolts. The adjusting block 12 and the threading disc 14 are fixedly connected by a return spring 30 for resetting the adjusting block 12. The surface of the threading disc 14 is threaded with a screw-in disc 11 that can adjust the protrusion length of the adjusting block 12. The surface of the screw-in disc 11 is provided with through grooves 27 arranged circumferentially. Through the setting of the through grooves 27, the operator can insert his hand into the through grooves 27 to drive the screw-in disc 11 to rotate, which facilitates the operation of the operator. The inner wall of the screw-in disc 11 is conical to squeeze and push the adjusting block 12, thereby adjusting the protrusion length of the adjusting block 12.

[0039] The rotating housing 21 is fixedly connected to a connecting pipe 15 for conveying coolant. The rotating housing 21 and the connecting pipe 15 are interconnected. The end of the connecting pipe 15 near the rotating housing 21 is threaded. The end of the connecting pipe 15 away from the rotating housing 21 is fixedly connected to a second fixing ring 19 and a first fixing ring 16 that provide installation points for the second connecting rod 20 and the first connecting rod 18. The outside of the connecting pipe 15 is provided with inner support plates 17 arranged circumferentially at equal intervals to support the inner wall of the pipe. This prevents the pipe from being crushed when the device is threading the pipe, which would affect the subsequent use of the pipe and improve the threading quality of the pipe.

[0040] The surface of the connecting tube 15 is slidably connected to a movable ring 26 that provides an installation point for the third link 28. The inner support plate 17 is rotatably connected to the movable ring 26 via a third link 28 that connects the inner support plate 17 and the movable ring 26. The inner support plate 17 is rotatably connected to the second fixed ring 19 and the first fixed ring 16 via a second link 20 and a first link 18 that connect the second fixed ring 19 and the first fixed ring 16. The third link 28, the second link 20, and the first link 18 are all in an inclined state. The surface of the connecting tube 15 is threadedly connected to a drive bolt 25 that can drive the movable ring 26 to move. The side of the drive bolt 25 near the movable ring 26 is fixedly connected to an installation rod 24 that connects the drive bolt 25 and the movable ring 26. The end of the installation rod 24 away from the drive bolt 25 is rotatably connected to the surface of the movable ring 26.

[0041] The inner support plate 17 has a hidden groove 31 on its surface that separates the nozzle 32 from the inner wall of the pipe. The inner wall of the hidden groove 31 is fixedly connected to the nozzles 32 arranged at equal intervals, which are used to spray coolant to cool the inner wall of the pipe. The nozzles 32 are in communication with the interior of the inner support plate 17, so that the coolant in the inner support plate 17 can be sprayed out through the nozzles 32.

[0042] A second corrugated pipe 29 is fixedly connected between the connecting pipe 15 and the inner support plate 17, connecting the inner support plate 17 and the connecting pipe 15. The two ends of the second corrugated pipe 29 are respectively connected to the inner support plate 17 and the connecting pipe 15. At the same time, the second corrugated pipe 29 can expand and contract accordingly with the expansion degree of the inner support plate 17, thereby ensuring the smooth operation of the device.

[0043] A support plate 7 is fixedly connected to the inner wall of the base 1 to support the liquid storage tank 5. The surface of the support plate 7 is fixedly connected to the liquid storage tank 5, which stores coolant. A water pump is installed inside the liquid storage tank 5 to deliver the coolant from the liquid storage tank 5 to the outside. A drain pipe 9 is fixedly connected inside the liquid storage tank 5, penetrating the surface of the liquid storage tank 5. One end of the drain pipe 9 inside the liquid storage tank 5 is fixedly connected to the outlet of the water pump, so that the coolant in the liquid storage tank 5 can be output to the outside. A through-hole drain pipe 9 is fixedly connected inside the ring cover 23. The injection pipe 10 on the surface of the ring cover 23 is fixedly connected to the drainage pipe 9 by a first corrugated pipe 8, which connects the drainage pipe 9 and the injection pipe 10. This allows the coolant in the storage tank 5 to be input into the rotating shell 21. At the same time, the first corrugated pipe 8 can expand and contract accordingly as the rotating shell 21 moves, so that the coolant in the storage tank 5 can be smoothly delivered to the rotating shell 21, ensuring the smooth operation of the device.

[0044] The surface of the base 1 is fixedly connected to a mounting shell 2 that provides installation space for two clamping blocks 4. The inner wall of the mounting shell 2 is slidably connected to two clamping blocks 4 for clamping and fixing the pipe. The opposite sides of the two clamping blocks 4 are V-shaped, and rubber pads are provided on the opposite sides of the two clamping blocks 4, so that the clamping blocks 4 and the pipe are in soft contact, avoiding the pipe from being crushed and ensuring the quality of the device.

[0045] The mounting housing 2 has a rotatable internal connection for a bidirectional threaded rod 3 that drives the two clamping blocks 4 to move. The bidirectional threaded rod 3 passes through the surface of the two clamping blocks 4 and is connected to the internal threads of the two clamping blocks 4. The threads at both ends of the bidirectional threaded rod 3 are matched with the internal threads of the two clamping blocks 4, so as to ensure that the bidirectional threaded rod 3 can smoothly drive the two clamping blocks 4 to move relative to or away from each other when rotating, thus ensuring the smooth operation of the device.

[0046] The implementation principle of a threading machine for low-voltage electrical engineering in this embodiment is as follows: When threading a pipe, the pipe is placed between two clamping blocks 4. Then, by rotating the bidirectional threaded rod 3, the two clamping blocks 4 are driven to move relative to each other, so that the two clamping blocks 4 clamp and fix the pipe. Then, the operator can drive the drive motor 6 to move closer to the pipe, so that the end of the pipe to be threaded is inserted between the dies 13, and the inner support plate 17 is inserted into the inside of the pipe. Then, by rotating the threading disc 11, the inner wall of the threading disc 11 is pressed against the surface of the adjusting block 12, thereby pushing the adjusting block 12 closer to the center of the threading disc 14. The return spring 30 is compressed, causing the die 13 to contact the outer surface of the pipe. Then, the drive bolt 25 is rotated to move on the connecting pipe 15, thereby pushing the moving ring 26 closer to the second fixed ring 19. This drives the third connecting rod 28, the second connecting rod 20, and the first connecting rod 18 from an inclined state to a vertical state, causing the inner support plate 17 to expand outward and its surface to contact the inner wall of the pipe, thus supporting the inner wall of the pipe. This prevents the pipe from being crushed when the subsequent device is threading the pipe, improving the effectiveness of the device.

[0047] Subsequently, the staff can start the water pump in the liquid storage tank 5, so that the coolant is injected into the rotating shell 21 through the drain pipe 9, the first corrugated pipe 8 and the injection pipe 10, and then injected into the connecting pipe 15 through the rotating shell 21. After that, it is sprayed onto the inner wall of the pipe through the second corrugated pipe 29 and the nozzle 32 to cool the pipe and avoid the pipe temperature from being too high, which would affect the pipe quality and thus improve the processing quality of the pipe.

[0048] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
