[0044] Reference Figures 1-2This embodiment provides a PE quick-connect pipe spin-fusion welding device, comprising a mounting platform 1, provided with a clamping module 3 and a rotating propulsion module 4. The clamping module 3 is used to clamp and fix the end of a pipe body 5, while the rotating propulsion module 4 is used to drive a male fastener 7 or female fastener 6 to rotate and move toward the pipe body 5.

[0047] Reference Figure 3 and Figure 4 The inner wall of the lower clamping plate 313 and the inner wall of the upper clamping plate 323 are adapted to each other to clamp the tube body 5; the outer wall of the end of the clamping tube body 5 is cylindrical, so as to adapt to the clamping of the arc-shaped lower clamping plate 313 and the upper clamping plate 323, avoiding scratches at the clamping position, thereby improving product quality.

[0049] With reference to Figure 5 , the lower mounting plate 312 is detachably connected with the lower clamping plate 313 through a first bolt, the end of the lower mounting plate 312 is provided with a first countersunk hole 3121 for accommodating the first bolt; the lower mounting plate 312 is fixedly connected with the lower shell 311 through a second bolt, the middle of the lower mounting plate 312 is provided with a second countersunk hole 3122 for accommodating the first bolt; the upper mounting plate 322 is detachably connected with the upper clamping plate 323 through a third bolt, the end of the upper mounting plate 322 is provided with a third countersunk hole 3221 for accommodating the third bolt; the upper mounting plate 322 is fixedly connected with the upper shell 321 through a fourth bolt, the middle of the upper mounting plate 322 is provided with a fourth countersunk hole 3222 for accommodating the fourth bolt; the lower clamping plate 313 is provided with a first screw hole matched with the first countersunk hole 3121, for the screwing and fixing of the first bolt; the lower shell 311 is provided with a second screw hole matched with the second countersunk hole 3122, for the screwing and fixing of the second bolt; the upper clamping plate 323 is provided with a third screw hole matched with the third countersunk hole 3221, for the screwing and fixing of the third bolt; the upper shell 321 is provided with a fourth screw hole matched with the fourth countersunk hole 3222, for the screwing and fixing of the fourth bolt.

[0050] With reference to Figure 5 , the second countersunk hole 3122 is used for accommodating the head of the second bolt, so as to avoid the head abutting against the lower clamping plate 313, thereby enabling the lower mounting plate 312 and the lower clamping plate 313 to be mutually attached; the fourth countersunk hole 3222 is used for accommodating the head of the fourth bolt, so as to avoid the head abutting against the upper clamping plate 323, thereby enabling the upper mounting plate 322 and the upper clamping plate 323 to be mutually attached, thereby improving the compactness of the structure of the utility model.

[0051] With reference to Figure 5 , the first countersunk hole 3121 is arranged on the outside of the side wall of the lower shell 311, thereby facilitating the mounting and dismounting of the first bolt, and further facilitating the mounting and dismounting of the lower clamping plate 313; the third countersunk hole 3221 is arranged on the outside of the side wall of the upper shell 321, thereby facilitating the mounting and dismounting of the third bolt, and further facilitating the mounting and dismounting of the upper clamping plate 323.

[0053] With reference to Figure 2 and Figure 3The clamping module 3 further comprises a protective plate 33 fixedly installed on the side wall of the upper shell 321 close to the rotary propulsion module 4, the protective plate 33 is arc-shaped and the axis points to the rotary propulsion module 4. In use, the protective plate 33 is buckled above the end of the male fastener 7 / female fastener 6 / tube body 5 and close to the side of the user, so as to avoid the problem of splashing of debris caused by friction.

[0054] With reference to Figure 3 The clamping module 3 further comprises a driving assembly 34, the driving assembly 34 comprises a first linear actuator 341 and a connecting arm 342, the front end of the connecting arm 342 is fixedly connected (for example, fixedly connected by bolts or fixedly connected by welding) with the top surface of the upper shell 321, the rear end of the connecting arm 342 is hingedly connected with the output shaft of the first linear actuator 341, the first linear actuator 341 is vertically arranged, and the bottom end of the shell of the first linear actuator 341 is hingedly connected with the rear side wall of the installation platform 1. When the output shaft of the first linear actuator 341 is elongated, the upper clamping assembly 32 can be driven to rotate towards the lower clamping assembly 31 until the upper clamping assembly 32 clamps the tube body 5; when the output shaft of the first linear actuator 341 is shortened, the upper clamping assembly 32 can be driven to rotate away from the lower clamping assembly 31 until the upper clamping assembly 32 releases the tube body 5.

[0055] With reference to Figure 6 The rotary propulsion module 4 comprises a driving motor 41, a clamping jaw 42 installed on the output shaft of the driving motor 41, and a horizontal movement assembly 43 for driving the driving motor 41 to move close to or away from the clamping module 3. The clamping jaw 42 is used to clamp the male fastener 7 or the female fastener 6; the driving motor 41 is used to rotate the male fastener 7 or the female fastener 6; the horizontal movement assembly 43 is used to drive the driving motor 41 and the male fastener 7 or the female fastener 6 to move in the direction of the tube body 5, so as to realize the rotary fusion.

[0056] With reference to Figure 6The horizontal moving assembly 43 comprises a slide rail 431, a slide block 432, a sliding plate 433, a vertical plate 434 and a second linear driver 435. The slide rail 431 is fixedly installed (for example, fixedly connected by bolts) on the upper surface of the mounting platform 1 and points to the clamping module 3 in the length direction. The slide block 432 is clamped on the slide rail 431 and can reciprocatingly slide along the length direction of the slide rail 431. The sliding plate 433 is transversely and fixedly installed (for example, fixedly connected by bolts) on the upper surface of the slide block 432. The driving motor 41 is fixedly installed (for example, fixedly connected by bolts) on the upper surface of the sliding plate 433. The vertical plate 434 is fixedly installed (for example, fixedly connected by bolts) on the top edge of the mounting platform 1. The outer shell end surface of the second linear driver 435 is fixedly connected (for example, fixedly connected by bolts) with the vertical plate 434. The output shaft of the second linear driver 435 penetrates through the through hole in the vertical plate 434 and is connected with the sliding plate 433. The second linear driver 435 can push the sliding plate 433 and the slide block 432 to reciprocatingly slide along the length direction of the slide rail 431, so as to drive the driving motor 41, the clamping jaw 42, the male fastener 7 or the female fastener 6 to move towards the direction of the pipe body 5, thereby realizing the rotary melting.

[0057] With reference to Figure 9 The surface of the male fastener 7 is integrally and fixedly connected with a supporting fin 711. The supporting fin 711 is hingedly connected with a clamping arm 71. A torsional spring is arranged at the hinged position, so that the tip of the clamping arm 71 has a tendency to rotate inwardly. The surface of the female fastener 6 is provided with a clamping groove 61 adapted to accommodate the clamping arm 71. The clamping groove 61 is provided with a check protrusion 611 for clamping the end portion of the clamping arm 71.

[0058] With reference to Figure 7 , Figure 8 , Figure 9 and Figure 10The clamping claw 42 comprises a cylindrical shell 421, a clamping jaw 422 and a sleeve 423. The cylindrical shell 421 is open at one end and closed at the other end. The clamping jaw 422 is fixedly connected to the side wall of the open end of the cylindrical shell 421 (for example, by integral fixing or by bolt fixing). The number and size of the clamping jaw 422 are matched with the number and size of the clamping groove 61. The sleeve 423 is coaxially arranged with the cylindrical shell 421. The sleeve 423 is fixedly installed at the center of the closed end of the cylindrical shell 421 (for example, by integral fixing). The sleeve 423 can be detachably connected to the output shaft of the driving motor 41 (for example, the side wall of the sleeve 423 is provided with an adjusting screw hole along the radial direction. An adjusting screw is threadedly connected in the adjusting screw hole. By rotating the adjusting screw, the end of the adjusting screw can be inserted into or extracted from the reserved hole in the side wall of the output shaft). When the female fastener 6 is used, the female fastener 6 is inserted into the inner cavity of the cylindrical shell 421 away from one end of the corresponding pipe body 5, so that the clamping jaw 422 is clamped into the clamping groove 61. Then, the female fastener 6 can rotate at the same speed and in the same direction as the clamping claw 42 for threading. When the male fastener 7 is used, the male fastener 7 is inserted into the inner cavity of the cylindrical shell 421 away from one end of the corresponding pipe body 5, so that the clamping jaw 422 is clamped between adjacent support fins 711. Then, the male fastener 7 can rotate at the same speed and in the same direction as the clamping claw 42 (a certain amount of free play is required until the clamping jaw 422 is in contact with the support fin 711) for threading.

[0059] With reference to Figures 7-9 The clamping jaw 422, the clamping arm 71 and the clamping groove 61 are each provided with three, thereby realizing stable clamping.

[0060] The cross section of the sliding block 432 is C-shaped, and the cross section of the sliding rail 431 is gourd-shaped. The sliding block 432 is buckled on the sliding rail 431 to avoid falling off. The sliding block 432 can reciprocally slide along the length direction of the sliding rail 431. The sliding rail 431 is provided with two and arranged in parallel with each other. The sliding block 432 is provided with four and arranged in pairs on the two sliding rails 431, thereby stably supporting the sliding plate 433.

[0061] With reference to Figure 7 With Figure 11The male fastener 7 and the female fastener 6 are respectively provided with a plurality of different sizes to adapt to the installation of the pipe body 5 with different diameters. The male fastener 7 and the female fastener 6 capable of being inserted and buckled together form a fastener group; the clamping claw 42 is provided with different sizes to adapt to different fastener groups. The end of the male fastener 7 and the end of the female fastener 6 are both in a cylindrical shape. The male fastener 7 and the female fastener 6 are inserted and buckled together, and the end of the male fastener 7 is inserted into the inner cavity of the end of the female fastener 6 (since the side wall of the end of the female fastener 6 needs to be arranged between the side wall of the end of the male fastener 7 and the clamping arm 71 to achieve clamping of the female fastener 6), so the radius R1 of the end of the male fastener 7 needs to be smaller than the radius R2 of the end of the female fastener 6, and the difference between the two radii is the wall thickness of the end of the female fastener 6. Therefore, the inner wall of the column shell 421 of the clamping claw 42 adapted to the fastener group is adapted to the outer diameter of the end of the female fastener 6 (that is, after the female fastener 6 is clamped on the clamping claw 42, the outer wall of the end of the female fastener 6 is in close contact with the inner wall of the column shell 421), and the clamping claw 42 further comprises a gasket ring in a ring shape. The outer wall of the gasket ring is adapted to the inner wall of the column shell 421, and the inner wall of the gasket ring is in video with the outer wall of the end of the male fastener 7. When the gasket ring is inserted into the column shell 421, the outer wall of the gasket ring is in close contact with the inner wall of the column shell 421. When the gasket ring is sleeved on the end of the male fastener 7, the inner wall of the gasket ring is in close contact with the outer wall of the end of the male fastener 7. Therefore, when the clamping claw 42 is used to clamp the male fastener 7, the gasket ring needs to be inserted into the inner cavity of the column shell 421 first, and then the end of the male fastener 7 is inserted into the column shell 421, so as to achieve stable clamping of the male fastener 7, and the driving motor 41 drives the male fastener 7 to rotate without eccentricity. Further ensure the reliability of the rotary fusion welding.

[0062] Referring to Figure 7 , Figure 9 and Figure 12 , the inner wall of the clamping claw 422 away from the column shell 421 is provided with a chamfer 4221 structure, the size and inclination angle of the chamfer 4221 are adapted to the inclined surface of the check convex 611, and when the clamping claw 422 is inserted into the clamping groove 61, the inner wall of the clamping claw 422 is in close contact with the outer cylindrical surface of the end of the female fastener 6 away from the pipe body 5, and the chamfer 4221 is in close contact with the inclined surface of the check convex 611, so as to achieve stable clamping of the female fastener 6.

[0063] The first linear driver 341 and the second linear driver 435 are both electric push rods, pneumatic push rods, hydraulic push rods or combinations thereof (for example, electro-hydraulic push rods).

[0064] The utility model further includes an electrical cabinet, which is fixedly installed in the inner cavity of the installation platform 1 through bolts. The first linear driver 341, the second linear driver 435 and the driving motor 41 are respectively connected with the electrical cabinet through wires and signal lines; the electrical cabinet is connected with an external power supply and an external computer through wires and signal lines, and the computer controls the start-stop and other working states of the first linear driver 341, the second linear driver 435 and the driving motor 41 in the utility model through the electrical cabinet, so as to realize rotary fusion.

[0065] The pipe body 5, the male fastener 7 and the female fastener 6 are made of polyethylene (PE), thereby having excellent spin melting property.

[0066] With reference Figure 1 The utility model also includes setting up the auxiliary support platform 2 of installation platform 1 side. Because pipe body 5 usually has greater length-diameter ratio, and clamping module 3 can only clamp the end of pipe body 5, therefore in order to avoid the end of pipe body 5 that is not clamped to be in the state of hanging down, using auxiliary support platform 2 supports the middle and the end of pipe body 5 that is not clamped. Auxiliary support platform 2 is the frame structure of wood or metal, and is all the conventional prior art scheme, and the specific structure will not be repeated.

[0067] The utility model has the advantages of simple structure and reliable function, through clamping module 3 clamping the end of pipe body 5, using the rotation of rotating propulsion module 4 drive male fastener 7 / female fastener 6 and move to the end of pipe body 5, make male fastener 7 / female fastener 6 and pipe body 5 rub and close tightly, realize spin melting, do not need to use the threaded connection to avoid threaded processing procedure, convenient and efficient, improve production and processing efficiency, and can improve the strength of the end of pipe body 5.

[0068] In the description of the utility model, it needs to be explained that the orientation or position relation indicated by the terms "upper", "lower", "left", "right" and the like is the orientation or position relation based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0069] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect" should be understood broadly, for example, can be fixed connection, can be detachable connection, or integrally connected, can be mechanical connection, can be electrical connection, can be direct connection, can be connected through intermediate medium, can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
