DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] like Figure 1-Figure 13 As shown, a fixed-length cutting device for processing a heat exchange module pipeline proposed in one embodiment of the present application includes: A carrier frame 1, a cutting frame 2 is rotatably mounted on the carrier frame 1, and a cutting blade 3 is rotatably mounted on the cutting frame 2; the cutting frame 2 is an existing structure, and the movement of the cutting frame 2 can be driven by a motor or manually; The clamping mechanism 4 includes two moving plates 401 vertically slidably mounted on the carrier 1, and a holding member 402 is mounted on the moving plate 401 for holding the pipe. A transmission assembly 403 for driving the moving plate 401 to move is mounted on the carrier 1; the two moving plates 401 are driven to approach each other by the transmission assembly 403, so that the two holding members 402 hold the pipe to be cut; The limiting mechanism 6 includes a driving plate 601 horizontally slidably mounted on the carrier 1, and a limiting baffle 602 is vertically constructed at the free end of the driving plate 601. The side of the limiting baffle 602 close to the cutting disc 3 is a contact surface, which is used to contact one end of the pipe. That is to say, before use, the limiting baffle 602 is first moved to adjust the distance between the limiting baffle 602 and the cutting disc 3. After the limiting baffle 602 is moved, the pipe is passed through the two holding members 402 until one end of the pipe contacts one side of the limiting baffle 602. In this way, after the pipe is cut by the cutting disc 3, it only needs to be moved again to fit with one side of the limiting baffle 602. The conveying mechanism 5 is installed on the moving plate 401. When the holding member 402 holds the pipeline and moves a distance away from the pipeline, the conveying mechanism 5 drives the pipeline to move in the direction of the limit baffle 602. The pipeline is placed between the two holding members 402 and one end of the pipeline abuts against the limit baffle 602. At this time, the two moving plates 401 are driven to approach each other through the transmission component 403, so that the two holding members 402 are pressed on the pipeline. Because the moving plate 401 will also drive the conveying mechanism 5 installed thereon to move when it moves, so at this time, after the holding member 402 is pressed on the pipeline, the conveying mechanism 5 also contacts the pipeline. After the cutting disc 3 completes one cut on the pipe, the moving plate 401 is driven away from the pipe by the transmission component 403, and the pipe is driven to move in the direction of the limit baffle 602 by the conveying mechanism 5, so that one end of the pipe to be cut is again in contact with the limit baffle 602, and then the pressing member 402 is pressed on the pipe by the transmission component 403, so that the pipe is quickly positioned and fixed-length cutting is achieved. There is no need for the staff to repeatedly move the pipe and measure the length of the extended pipe, which is more convenient to use, indirectly improving work efficiency and reducing the workload of the staff.

[0020] like Figure 1 and Figure 5As shown, in some embodiments, the conveying mechanism 5 includes a moving frame 501 vertically slidably mounted on a moving plate 401, wherein a plurality of guide rollers 502 are mounted in a horizontal array on one of the moving frames 501, and two transmission rollers 503 are rotatably mounted on the other moving frame 501, and both transmission rollers 503 are provided with transmission wheels 504, and a transmission belt 505 for contacting the outer side of the pipeline is installed between the two transmission rollers 503, and a resistance spring piece 506 is installed between the moving frame 501 and the moving plate 401, and a driving component 7 for driving one of the transmission rollers 503 to rotate is installed on the supporting frame 1. The design of the resistance spring piece 506 is that when the two holding members 402 hold the pipeline, the transmission belt 505 guides the roller 502 to contact the pipeline, and the resistance spring piece 506 is in a compressed state, and when the pipeline needs to be moved after completing one cutting, the moving plate 401 is away from one end of the pipeline so that The holding member 402 is no longer in contact with the pipe, and the interfering spring piece 506 is still in a compressed state, that is, the guide roller 502 and the transmission belt 505 are still in contact with the pipe, and then the driving component 7 will drive one of the transmission rollers 503 to rotate, and the rotation of the transmission roller 503 will drive the transmission wheel 504 to rotate. Because a transmission belt 505 is installed between the two transmission wheels 504, the transmission belt 505 will move at this time. Because the transmission belt 505 is in contact with the pipe, the movement of the transmission belt 505 will drive the pipe to move in the direction of the limit baffle 602 until the pipe is in contact with the limit baffle 602 again. Multiple guide rollers 502 play a guiding role, making the pipe move more smoothly. The use of the transmission belt 505 to push the pipe to move can be more convenient when moving a longer pipe, and the way the transmission belt 505 drives the pipe occupies less space.

[0021] like Figure 1-Figure 5As shown, in some embodiments, the transmission assembly 403 includes a driving sleeve 4031 vertically and rotatably mounted on the carrier 1, and a bidirectional thread is symmetrically opened on the outer circumference of the driving sleeve 4031, and two movable plates 401 are symmetrically threaded on the driving sleeve 4031, and a driving shaft 4032 is horizontally and rotatably mounted on the carrier 1, and a motor for driving the driving shaft 4032 to rotate is installed on the carrier 1, and a linkage assembly 8 acting on the driving shaft 4032 and the driving sleeve 4031 is installed on the carrier 1. When the driving shaft 4032 rotates, the driving sleeve 4031 is driven to rotate through the linkage assembly 8, wherein, after the holding member 402 holds the pipe, the driving shaft 4032 rotates in the opposite direction to drive the driving assembly 7 to drive one of the driving rollers 503 to rotate. In this embodiment, the rotation of the motor will drive the driving shaft 4032 to rotate, and the driving shaft 4032 will rotate when rotating. The linkage assembly 8 will drive the driving sleeve 4031 to rotate. Since the movable plate 401 is symmetrically threaded on the driving sleeve 4031, the rotation of the driving sleeve 4031 will drive the two movable plates 401 to move closer to and away from each other. Specifically, when the driving shaft 4032 rotates forward to drive the driving sleeve 4031 to rotate, the two movable plates 401 move closer to each other, and when the driving shaft 4032 rotates reversely to drive the driving sleeve 4031 to rotate, the two movable plates 401 move away from each other. When it is necessary to push the pipe in the clamped state, the motor drives the driving shaft 4032 to reverse so that the two movable plates 401 move away from each other. At the same time, the reversal of the driving shaft 4032 can also drive one of the transmission rollers 503 to rotate, thereby realizing the movement of the transmission belt 505 to move the conveying pipe, thereby ensuring the overall continuity and further reducing the time required to move the pipe.

[0022] like Figure 1 , Figure 3 , Fig. 9 and Fig.12As shown, in some embodiments, the driving assembly 7 includes two driving rollers 701 rotatably mounted on the carrier 1, and the two driving rollers 701 are provided with driving wheels 702, and the two driving wheels 702 are distributed up and down and a driving belt 703 is installed therebetween, a first bevel gear 704 is slidably mounted on one of the driving rollers 701, a second bevel gear 705 for meshing with the first bevel gear 704 is installed on the driving shaft 4032, a driving screw 706 is threadedly inserted into the driving roller 701, and a pressure cover 707 for contacting the end face of the first bevel gear 704 is constructed at the free end of the driving screw 706, and a connecting spring 708 is installed between the first bevel gear 704 and the driving roller 701, wherein one The transmission roller 503 is provided with an execution wheel 709 for meshing with the driving belt 703, that is to say, when the pressure cover 707 is twisted, the pressure cover 707 will contact the first bevel gear 704, thereby driving the first bevel gear 704 to move. At this time, the connecting spring 708 is compressed, so that the first bevel gear 704 and the second bevel gear 705 are no longer meshed. In this state, the rotation of the driving shaft 4032 will not drive the driving roller 701 to rotate, thereby not causing the execution wheel 709 to rotate. Therefore, at this time, the driving shaft 4032 will only drive the driving sleeve 4031 to rotate regardless of forward or reverse rotation. When the pipe is placed on the two holding members 402, the first bevel gear 704 will not mesh with the second bevel gear The first bevel gear 704 and the second bevel gear 705 are meshed, so the pressing member 402 can be pressed on the pipeline by the driving shaft 4032 and the driving belt 703 will not move to affect the pressing of the pipeline. After the pressing of the pipeline is completed, the first bevel gear 704 and the second bevel gear 705 can be meshed by screwing the pressure cover 707. In this way, when the driving shaft 4032 rotates in the opposite direction, the two pressing members 402 move away from each other. As the driving shaft 4032 rotates in the opposite direction, the first bevel gear 704 rotates, thereby realizing the rotation of the second bevel gear 705. When the second bevel gear 705 rotates, it drives the driving roller 701 to rotate. When the driving roller 701 rotates, it drives the driving wheel 702 installed thereon to rotate. Thereby, the driving belt 703 is moved, and when the driving belt 703 moves, it will drive the execution wheel 709 meshing with it to rotate. Specifically, the driving belt 703 can be an existing chain, and the execution wheel 709 and the driving wheel 702 can be existing sprockets. When the execution wheel 709 rotates, it will drive one of the transmission rollers 503 to rotate, thereby realizing the movement of the transmission belt 505 to push the pipeline to move (at this time, the transmission belt 505 still maintains a state of conflict with the pipeline). After the movement, the pressure cover 707 is screwed so that the first bevel gear 704 and the second bevel gear 705 are no longer meshed, and then the drive shaft 4032 is rotated forward so that the holding member 402 is pressed on the pipeline again to complete the pressing of the pipeline.

[0023] like Figure 1 , Figure 2 and Figure 7As shown, in some embodiments, the linkage assembly 8 includes a transmission sleeve 801 and a transmission rod 802 rotatably mounted on the carrier 1, the transmission sleeve 801 and the transmission rod 802 are distributed up and down and are both equipped with a synchronous wheel 803, a synchronous belt 804 is installed between the two synchronous wheels 803, one vertical section of the synchronous belt 804 passes through the driving sleeve 4031, a spiral guide groove 805 is opened on the inner circumference of the driving sleeve 4031, a guide block 806 located in the spiral guide groove 805 is installed on the synchronous belt 804, and the driving shaft 4032 is connected to the transmission sleeve 801, that is, when the driving shaft When the rod 4032 rotates, it will drive the transmission sleeve 801 to rotate, and as the transmission sleeve 801 rotates, it will drive the synchronous wheel 803 installed thereon to rotate. Because a synchronous belt 804 is installed between the two synchronous wheels 803, the synchronous belt 804 will move at this time. As the synchronous belt 804 moves, the guide block 806 installed thereon will move. At this time, the guide block 806 will move in the spiral guide groove 805, thereby forcing the driving sleeve 4031 to rotate. The rotation of the driving sleeve 4031 will drive the two moving plates 401 to move closer to or away from each other, so as to realize the movement of the holding member 402.

[0024] like Figure 2 and Figure 7As shown, in some embodiments, a plurality of mounting grooves 9 are provided in a circular array on the outer circumference of the driving shaft 4032, a driving block 10 is slidably installed in the mounting groove 9, and two opposite edges of the free end of the driving block 10 are respectively constructed with a first inclined surface 11 and a second inclined surface 12, the angle between the first inclined surface 11 and the outer sectional surface of the driving shaft 4032 is smaller than the angle between the second inclined surface 12 and the outer sectional surface of the driving shaft 4032, and a plurality of triangular grooves 13 are provided on the inner circumference of the transmission sleeve 801 for inserting the free end of the driving block 10, Specifically, when the driving shaft 4032 rotates forward, the first inclined surface 11 contacts the inclined surface corresponding to the triangular groove 13, and when the driving shaft 4032 rotates reversely, the second inclined surface 12 contacts the inclined surface corresponding to the triangular groove 13. Because the angle between the first inclined surface 11 and the outer tangent surface of the driving shaft 4032 is smaller than the angle between the second inclined surface 12 and the outer tangent surface of the driving shaft 4032, the driving force provided by the driving shaft 4032 to the transmission sleeve 801 in the reverse direction is greater than the driving force provided by the driving shaft 4032 to the transmission sleeve 801 in the forward direction. 1 provides a driving force, so that when the driving shaft 4032 rotates forward so that the holding piece 402 contacts the pipe, if the holding piece 402 needs to move away from the pipe, the reverse rotation of the driving shaft 4032 has enough force to overcome the threaded fastening force provided by the driving sleeve 4031. The support frame 1 is provided with a limiting member 14 for limiting the rotation angle of the transmission sleeve 801. That is to say, after the holding piece 402 is pressed in the pipe, if the pipe needs to be extended for a certain distance, the reverse rotation of the driving shaft 4032 will cause the driving block 10 on the driving shaft 4032 to be inserted into the triangular groove 13, thereby driving the transmission sleeve 801 to rotate. Due to the restriction of the limiting member 14, the transmission sleeve 801 will only rotate a small amount and then stop rotating. At this time, if the driving shaft 4032 continues to rotate, multiple driving blocks 10 will be repeatedly inserted and disengaged from the triangular groove 13, thereby preventing the transmission sleeve 801 from continuing to rotate, ensuring that the holding piece 402 needs to move a larger distance when it is pressed on the pipe again.

[0025] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the limiting member 14 includes a driving ring plate 1401 rotatably mounted on the carrier 1, the driving ring plate 1401 is coaxial with the transmission sleeve 801, a plug-in screw 1402 is threadedly inserted on the driving ring plate 1401, a plurality of limiting plug holes 1403 for plugging the plug-in screw 1402 are provided in a circular array around the axis of the driving ring plate 1401 on the carrier 1, a first stopper 1404 located inside the driving ring plate 1401 is constructed at one end of the transmission sleeve 801, and a second stopper 1405 for contacting the first stopper 1404 is constructed on the inner side of the driving ring plate 1401, when the pressing member After 402 presses the pipe, the driving ring plate 1401 can be rotated at this time so that the second stop bar 1405 is at a certain distance from the first stop bar 1404, and then the plug-in screw 1402 is screwed so that the plug-in screw 1402 is inserted into the limiting socket 1403 to prevent the driving ring plate 1401 from rotating. When the driving shaft 4032 reverses to drive the transmission sleeve 801 to rotate, the first stop bar 1404 will contact the second stop bar 1405, thereby preventing the transmission sleeve 801 from continuing to rotate, effectively reducing the pressure holding member 402 from moving a long distance due to the reversal of the driving shaft 4032.

[0026] like Figure 1 , Figure 8 and Fig.10As shown, in some embodiments, a rotating shaft 15 is rotatably mounted on the carrier 1, the second bevel gear 705 is rotatably mounted on the rotating shaft 15, the rotating shaft 15 is coaxially rotatably mounted on one end of the driving shaft 4032, a mounting cylinder 16 is mounted on the carrier 1, a wedge plate 17 is elastically slidably mounted on the mounting cylinder 16, a wedge groove 18 for inserting the wedge plate 17 is opened on the outer peripheral side of the rotating shaft 15, and a plurality of arc grooves 19 are opened in a circular array at one end of the driving shaft 4032, and the arc groove 19 is elastically slidably mounted on the mounting cylinder 16. The arc-shaped slide plate 20 is inserted into the pipe for sliding, and one end of the arc-shaped slide plate 20 is located outside and is configured as an inclined surface. A plurality of arc-shaped inclined grooves 21 for inserting the arc-shaped slide plate 20 are provided in a circular array on one end of the rotating shaft 15. When the pressing member 402 is pressed on the pipe and the cutting blade 3 has cut the pipe, the driving shaft 4032 rotates in the opposite direction, which makes the plane of one end of the arc-shaped slide plate 20 contact the arc-shaped inclined groove 21, thereby making the rotating shaft 15 rotate together (at this time, the inclined surface of the wedge plate 17 and the wedge groove 18 are in contact with each other). The inclined surface of the rotating shaft 15 does not affect the rotation of the rotating shaft 15). When the rotating shaft 15 rotates, it will drive the second bevel gear 705 to rotate, thereby realizing the movement of the transmission belt 505. As the transmission belt 505 moves and drives one end of the pipeline to contact the limit baffle 602, the driving shaft 4032 rotates forward so that the holding members 402 approach each other and hold the pipeline again. When the driving shaft 4032 rotates forward, the inclined surface of the arc-shaped slide plate 20 contacts the inclined surface of the arc-shaped inclined groove 21, and at this time, the wedge plate 17 The plane just conflicts with the plane of the wedge groove 18, so the rotating shaft 15 will not rotate at this time, so the second bevel gear 705 installed on the rotating shaft 15 will not rotate either, so there is no need for the staff to twist the pressure cover 707 to separate the first bevel gear 704 from the second bevel gear 705, which further reduces the workload of the staff and is more convenient to use. It is only necessary to separate the first bevel gear 704 from the second bevel gear 705 when clamping the pipe for the first time to prevent the transmission belt 505 from moving.

[0027] like Figure 5 and Fig.10As shown, in some embodiments, the holding member 402 includes a holding plate 4021 symmetrically and rotatably mounted on the moving plate 401, a transmission plate 4022 is slidably mounted on the moving plate 401, and hinge rods 4023 are symmetrically hinged on the transmission plate 4022. The free ends of the two hinge rods 4023 are respectively hinged on the two transmission plates 4022, and elastic pull rods 4024 are horizontally slidably inserted on the transmission plate 4022. A plurality of positioning holes 4025 for inserting the elastic pull rods 4024 are vertically opened on the moving plate 401, and the holding plate 402 can be controlled according to the diameter of the pipe. 1 angle, which improves the applicability.
