Compared with the prior art method of threading the pipe by workers holding the head end of the inner pipe and the head end of the sleeve and walking a certain length of pipe threading distance in the preset pipe threading direction, in this embodiment, the first driving structure 4 drives the first positioning structure 1 to move in the preset pipe threading direction, which can drive the head end of the sleeve to move in the preset pipe threading direction, and the second driving structure 5 drives the second positioning structure 2 to move in the preset pipe threading direction, which can drive the head end of the inner pipe to move in the preset pipe threading direction, so that machine threading can replace manual threading, which greatly reduces the labor intensity of workers and the labor cost of water pipe manufacturers.

[0029] like Figure 2 , 5As shown, in some specific embodiments, the first positioning structure 1 includes a first mounting arm 12, and a first positioning assembly 11 disposed on the first mounting arm 12, and the head end of the sleeve can be positioned and connected to the first positioning assembly 11. The first driving structure 4 includes a first conveying member 41 arranged along a preset pipe threading direction, and a first driving member 42 for driving the first conveying member 41 to reciprocate along the preset pipe threading direction. The first mounting arm 12 is positioned and connected to the first conveying member 41, and can drive the first positioning assembly 11 to move synchronously with the movement of the first conveying member 41. Compared with the prior art in which a worker manually threading a pipe, after holding the head end of the inner pipe and the head end of the casing and walking a certain length in a preset threading direction, needs to manually hold the head end of the inner pipe and the head end of the casing and return to the initial position and walk a certain length to replace the next group of inner pipes and casings for threading operations, in this embodiment, since the first conveying member 41 reciprocates along the preset threading direction, the head end of the casing can move along with the first positioning component 11 and the first conveying member 41 in the preset threading direction for threading operations, and can also return to the initial position along with the first positioning component 11 and the first conveying member 41, which is convenient for replacing the next group of inner pipes and casings for threading operations, and further reduces the labor intensity of workers and the labor cost of water pipe manufacturers.

[0030] like Figure 2 As shown, in some specific embodiments, the first positioning component 11 includes a first main clamp 111 and a first auxiliary clamp 112 arranged relatively to each other. The first main clamp 111 and the first auxiliary clamp 112 have an open state that is relatively far apart, and a use state that is relatively close to each other. When they are in the use state, the head end of the sleeve can be clamped and positioned between the first main clamp 111 and the first auxiliary clamp 112, which facilitates the quick installation of the head end of the sleeve on the first positioning component 11, or the quick removal from the first positioning component 11, and the pipe threading efficiency is higher.

[0031] In some specific embodiments, the first positioning assembly 11 further includes a sleeve 113, and a pipe threading channel 1131 is formed inside the sleeve 113 for the inner tube to pass through. The head end of the sleeve can be sleeved outside the sleeve 1131, so that the head end of the sleeve is supported outside the sleeve 113, and the inner tube moves relative to the sleeve by moving along the pipe threading channel 1131, which is conducive to the movement of the inner tube relative to the sleeve for pipe threading. A positioning groove 1111 is recessed on one side of the first main clamp 111 close to the first auxiliary clamp 112, and a positioning groove 2 1121 is recessed on one side of the first auxiliary clamp 112 close to the first main clamp 111 and arranged opposite to the positioning groove 1111. When the first main clamp 111 and the first auxiliary clamp 112 are in use, a clamping channel for clamping the head end of the positioning sleeve can be formed between the sleeve 113, the positioning groove 1111 and the positioning groove 2 1121.

[0032] In some specific embodiments, the socket is made of hard materials such as metal and rubber and has a certain supporting strength so as to stably support the head end of the sleeve outside the socket 113, which is beneficial for the inner tube to move freely and smoothly along the tube passage 1131 and is beneficial for the head end of the sleeve to be more stably clamped and positioned in the clamping channel. The shape of the tube threading channel 1131 is matched with the shape of the inner tube. In the present embodiment, the tube threading channel 1131 is set as a circular structure, which is suitable for the tube threading operation with a circular inner tube. The sleeve 113 is set as a cylindrical structure. At this time, the positioning groove 1111 and the positioning groove 2 1121 can be respectively set as arc groove structures matching the cylindrical structure, so as to stably clamp and position the head end of the sleeve in the clamping channel; as another embodiment of the present utility model, the tube threading channel can also be set as an elliptical structure, which is suitable for the tube threading operation with an oblate inner tube. At this time, the sleeve 113 can be set as an elliptical cylinder structure, and the positioning groove 1 1111 and the positioning groove 2 1121 can be respectively set as elliptical arc groove structures matching the elliptical cylinder structure, so as to stably clamp and position the head end of the sleeve in the clamping channel; in other embodiments, the tube threading channel can also be set as square, triangle or other shaped structures to be suitable for the tube threading operation with inner tubes of other shapes such as square and triangle.

[0033] like Figure 3 , 5 As shown, in some specific embodiments, the second positioning structure 2 includes a second mounting arm 22, and a second positioning assembly 21 disposed on the second mounting arm 22, and the head end of the inner tube can be positioned and connected to the second positioning assembly 21. The second driving structure 5 includes a second conveying member 51 arranged along a preset pipe threading direction, and a second driving member 52 for driving the second conveying member 51 to reciprocate along the preset pipe threading direction, and the second mounting arm 22 is positioned and connected to the second conveying member 51, and can drive the second positioning assembly 21 to move synchronously with the movement of the second conveying member 51. Compared with the prior art in which a worker manually threading a pipe, after holding the head end of the inner pipe and the head end of the casing and walking a certain length in a preset threading direction, needs to manually hold the head end of the inner pipe and the head end of the casing and return to the initial position and walk a certain length to replace the next group of inner pipes and casings for threading operations, in this embodiment, since the second conveying member 51 reciprocates along the preset threading direction, the head end of the inner pipe can move along with the second positioning component 21 and the second conveying member 51 in the preset threading direction for threading operations, and can also return to the initial position along with the second positioning component 21 and the second conveying member 51, which is convenient for replacing the next group of inner pipes and casings for threading operations, further reducing the labor intensity of workers and the labor cost of water pipe manufacturers.

[0034] like Figure 3As shown, in some specific embodiments, the second positioning component 21 includes a second main clamp 211 and a second auxiliary clamp 212 arranged relatively to each other. The second main clamp 211 and the second auxiliary clamp 212 have an open state that is relatively far apart, and a use state that is relatively close to each other. When it is in the use state, the head end of the inner tube can be clamped and positioned between the second main clamp 211 and the second auxiliary clamp 212, which facilitates the quick installation of the head end of the inner tube on the second positioning component 21, or the quick removal from the second positioning component 21, thereby further improving the pipe threading efficiency.

[0035] In some specific embodiments, the third positioning structure 3 includes a third mounting arm 32, the third mounting arm 32 includes a positioning shaft 321 and a positioning wheel 322 connected to the positioning shaft 321, and the outer periphery of the positioning wheel 322 is concavely provided with a traction groove 3221 along its circumferential direction. The third positioning assembly 31 includes a traction member 311 and a clamp 312 connected to the head end of the traction member 311, and the traction member 311 is configured in a hook shape and hung on the traction groove 3221. The end of the inner tube can be positioned and connected to the clamp 312, and the head end of the sleeve can be sleeved toward the head end of the traction member 311 through the end of the traction member 311 and positioned in the clamping channel on the first positioning structure 1. When the sleeve moves toward a preset pipe threading direction with the first positioning structure 1, the positioning wheel 322 can rotate around the axis of the positioning shaft 321 to guide the sleeve to move along the traction groove 3221, so as to keep the traction member 311 hung on the traction groove 3221 while allowing the sleeve sleeved outside the traction member 311 to move relative to the traction groove 3221 to be sleeved outside the inner tube.

[0036] like Figure 4As shown, in some specific embodiments, the clamp 312 includes a connector 3121, a mounting kit 3122 and a telescopic kit 3123, and the connector 3121 has a positioning end that can extend into the inner end of the inner tube, and a connecting end away from the positioning end. The mounting kit 3122 is connected to the head end of the traction member 311, and the connector 3121 is sleeved in the mounting kit 3122 and connected to the mounting kit 3122 through the connecting end. The telescopic kit 3123 is sleeved in the mounting kit 3122 and outside the connector, and can telescopically move relative to the mounting kit 3122 and the connector 3121 between a use state close to the positioning end and an open state away from the positioning end. When it is in the use state, the inner tube end can be clamped and positioned between the positioning end and the telescopic kit 3123, so that the inner tube end can be quickly installed on the third positioning assembly 31 or quickly removed from the third positioning assembly 31, further improving the pipe threading efficiency. A reset member (not shown in the figure) is arranged between the telescopic kit 3123 and the installation kit 3122. The reset member may be an elastic member such as a spring or elastic silicone, which can provide an operating force to keep the telescopic kit 3123 in a use state, and facilitate the quick installation of the inner tube end between the positioning end and the telescopic kit 3123. The installation kit 3122 and the head end of the traction member 311 are detachably connected, and the installation kit 3122 and the connecting end are detachably connected. The detachable connection structure may be a threaded connection structure or a snap connection structure, etc., to facilitate the replacement of the clamp 312. In other embodiments, the head end or the connecting end of the traction member 311 and the installation kit 3122 may also be set as an integral structure or fixedly connected as a whole by welding or other methods to improve the stability of the connection between the clamp 312 and the traction member 311. In other embodiments, the connecting end may also be directly connected to the head end of the traction member 311, or simultaneously connected to the installation kit 3122 and the head end of the traction member 311. As another embodiment of the present invention, the clamp 312 may also only include the connecting head 3121 and the telescopic kit 3123 , and the end of the inner tube may be staggered and positioned between the connecting end and the telescopic kit 3123 .

[0037] In some specific embodiments, the cross section of the traction member 311 is set to a circular structure, which is suitable for the pipe-threading operation of a circular inner pipe. As another embodiment of the utility model, the cross section of the traction member 311 can also be set to an elliptical structure or a combined structure composed of at least two circular structures connected side by side, so as to be suitable for the pipe-threading operation of an oblate inner pipe.

[0038] In other specific embodiments, a spherical expansion portion with a width greater than that of the traction member 311 is further provided at the end of the traction member 311 to expand the interior of the sleeve when the sleeve is sleeved outside the traction member 311, thereby preventing the sleeve from moving smoothly relative to the traction member 311 due to the inner walls of the sleeve sticking together.

[0039] like Figure 1 As shown, in some specific embodiments, the first positioning structure 1 and the second positioning structure 2 are arranged at intervals to form a movable space for the portion of the inner tube between the first positioning structure 1 and the second positioning structure 2 to bend and deform, thereby ensuring that the portion of the inner tube between the first positioning structure 1 and the second positioning structure 2 can be freely bent and deformed as the first positioning structure 1 and the second positioning structure 2 move in a preset pipe penetration direction to smoothly penetrate into the casing, thereby avoiding the smoothness of the pipe penetration operation being affected due to the portion of the inner tube between the first positioning structure 1 and the second positioning structure 2 bending when the first positioning structure 1 and the second positioning structure 2 move in the preset pipe penetration direction. Due to the different materials or shapes used to make the inner tube, the inner tubes of different materials or shapes have different softness, that is, the size of the activity space required for the inner tubes of different softness to bend and deform is also different. In this embodiment, the relative distance between the first positioning structure 1 and the second positioning structure 2 can be adjusted by the first driving structure 4 and the second driving structure 5. For example, the second driving structure 5 drives the second positioning structure 2 toward the direction away from the third positioning structure 3 of the first positioning structure 1 to an appropriate size of the activity space, thereby being able to adapt to the size of the activity space required for inner tubes of different softness, so that the tube-piercing processing device can adapt to the tube-piercing operations of inner tubes of different softness and has a wide range of applications.

The second positioning assembly 21 further includes a second positioning member 213 and a second switch member 214 disposed on the second mounting arm 22, and the second switch member 214 is used to control the second main clamp 211 and the second auxiliary clamp 212 to move away from each other to an open state, and to move closer to each other to a use state. The second mounting arm 22 is configured as a horizontally arranged plate structure, the second positioning member 213 is connected to the lower side of the second mounting arm 22 and extends in a direction close to the first positioning structure 1, the second main clamp 211 and the second auxiliary clamp 212 are installed on the second positioning member 214 at one end close to the first positioning structure 1, and the second positioning member 214 can extend into the accommodating area to make the second main clamp 211 and the second auxiliary clamp 212 close to each other with the first main clamp 111 and the first auxiliary clamp 112, so that after the pipe threading is completed, the head end of the inner pipe and the head end of the casing can be closer, and the completion degree of the pipe threading operation is higher. In other embodiments, the first switch member 115 can also be arranged on the first positioning member 114, or simultaneously arranged on the first mounting arm 12 and the first positioning member 114, or the second switch member 214 can also be arranged on the second positioning member 213, or simultaneously arranged on the second mounting arm 22 and the second positioning member 213.

[0042] In some specific embodiments, a third driving structure 6 is further included for driving the positioning shaft 321 to rotate around the axis of the positioning shaft 321. The positioning wheel 322 is relatively fixedly connected to the positioning shaft 321 and can rotate around the axis of the positioning shaft 321 as the positioning shaft 321 rotates, so that the positioning wheel 322 can rotate relative to the axis of the positioning shaft 321 under the drive of the third driving structure 6 to cooperate with the movement of the sleeve toward the preset pipe-threading direction, which is more conducive to guiding the sleeve to move smoothly in the preset pipe-threading direction. In other embodiments, the third driving structure 6 may not be provided, and the positioning wheel 322 is directly rotatably connected to the positioning shaft 321, so that the positioning wheel 322 can also rotate relative to the axis of the positioning shaft 321 in cooperation with the movement of the sleeve when the sleeve moves toward the preset pipe-threading direction.

[0043] In some specific embodiments, a frame 7 is further included, and the first mounting arm 12 and the second mounting arm 22 are respectively and slidably connected to the frame 7 along the length direction of the frame 7, and the third mounting arm 32 is rotatably connected to the frame 7. The first mounting arm 12 and the second mounting arm 22 are respectively arranged along the width direction of the frame 7 and protrude from both sides of the frame 7. A plurality of first positioning components 11 are respectively arranged at two ends of the first mounting arm 12 protruding from the frame 7, a plurality of second positioning components 21 are respectively arranged at two ends of the second mounting arm 22 protruding from the frame 7, and a plurality of third positioning components 31 are respectively arranged at two ends of the third mounting arm 32 protruding from the frame 7, and the third positioning components 31 are respectively arranged at two ends of the third mounting arm 32 protruding from the frame 7, and the third positioning components 31 are respectively arranged at two ends of the third mounting arm 32 protruding from the frame 7, so that the pipe threading processing device can simultaneously perform pipe threading operations of multiple groups of inner pipes and sleeves. Compared with the prior art in which a worker can only perform pipe threading operations of one group of inner pipes and sleeves at a time, the pipe threading processing device of this embodiment greatly improves the work efficiency, and each group of first positioning components 11, second positioning components 21 and third positioning components 31 are arranged adjacent to each other, and the space arrangement is compact, which can greatly reduce the work space occupied by the pipe threading operation. Moreover, the moving speed of the first positioning structure 1 and the second positioning structure 2 can be set faster than the walking speed of workers in the prior art, so that the machine pipe threading speed is faster than the manual pipe threading speed, which can further improve the pipe threading efficiency and reduce the time cost invested by water pipe manufacturers.
