DETAILED DESCRIPTION

[0024] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious variants can be thought of by those skilled in the art.

[0025] Reference Figures 1-5As shown, a pipe joint inserting mechanism with a locating function comprises an operation table 1, a back plate 2 arranged at the rear end of the top surface of the operation table 1, and a notch arranged at the front end of the top surface of the operation table 1, one side of the inside of the notch is provided with a pipe clamping tool 3 for fixing the pipe, and the other side of the inside of the notch is provided with a flaring and inserting mechanism for installing the end joint of the pipe;

[0026] Through the arrangement of the flaring and inserting mechanism, the flaring and inserting mechanism can perform flaring and joint inserting operations on the end of the pipe in sequence in a short time after the pipe clamping tool 3 completes the fixation of the pipe to be processed, so that the flaring and inserting mechanism integrates the flaring machine and the joint inserting machine in the prior art, making the flaring and joint inserting of the pipe more convenient, improving the work efficiency and enhancing the practicability;

[0027] In addition, the pipe clamping tool 3 is a conventional automatic pipe clamping tool in the prior art, and its technical features have been disclosed in the prior art and are well known by the public. The specific structure and operating principle of the pipe clamping tool 3 will not be described in detail, and the operating principle is similar to that of the flaring and inserting integrated machine for pipe assembly disclosed in the prior art with the publication number CN117920874A.

[0028] Specifically, referring to Figures 1-5 As shown, it is worth noting that the flaring and inserting mechanism comprises a traveling frame 4 arranged in a sliding manner at the bottom of the operation table 1, an active seat 5 is arranged above the vertical surface of the traveling frame 4, one side of the active seat 5 facing the pipe clamping tool 3 is respectively provided with a flaring shaft 8 and an inserting shaft 6, the end of the flaring shaft 8 is elastically stretched with a flaring plug 9, the end of the inserting shaft 6 is pulled and inserted with a product joint 7, the side of the traveling frame 4 away from the pipe clamping tool 3 is provided with a pushing component, and the lower surface of the traveling frame 4 is provided with a reversing component;

[0029] After the pipe to be processed is fixed by the pipe clamping tool 3, first, the pushing component is used to slide the traveling frame 4 towards the pipe clamping tool 3, so that the flaring plug 9 is inserted into the end of the pipe, expanding the end of the pipe, then the pushing component resets the traveling frame 4, and the active seat 5 slides to one side under the action of the reversing component, moving the product joint 7 to the position of the original flaring plug 9, and then the pushing component is used again to slide the traveling frame 4 towards the pipe clamping tool 3, so that the product joint 7 is inserted into the end of the pipe, thereby realizing the inserting cooperation between the product joint 7 and the end of the pipe, and facilitating the flaring and inserting forming of the pipe.

[0030] Further, referring to Figure 2 As shown, it is worth noting that the pushing component comprises a mounting seat 14 mounted on the outer side of the bottom surface of the operation table 1, an electric cylinder 15 is mounted on the inner side wall of the mounting seat 14, and the telescopic end of the electric cylinder 15 is fixedly connected with the traveling frame 4;

[0031] When the electric cylinder 15 is turned on, the telescopic end of the electric cylinder 15 drives the traveling frame 4 to slide on the bottom surface of the operating table 1, thereby conveniently controlling the traveling frame 4 to slide toward or away from the pipe clamping tool 3.

[0032] Further, refer to Figure 1 and Figure 4 As shown, it is worth noting that a C-shaped mounting frame 16 is fixedly embedded on the top surface of the operating table 1, and second slide rails 18 are horizontally installed on both sides of the bottom surface of the mounting frame 16. A second slide seat 17 fixedly connected to the top surface of the traveling frame 4 is slidably provided on the second slide rail 18;

[0033] Through the arrangement of the second slide rail 18 and the second slide seat 17, when the electric cylinder 15 is started and the traveling frame 4 moves on the bottom surface of the operating table 1, the second slide seat 17 can synchronously slide in the same direction on the second slide rail 18, and then the second slide seat 17 cooperates with the second slide rail 18 to effectively limit the propulsion trajectory and direction of the traveling frame 4, thereby ensuring the stability of the traveling frame 4 during movement.

[0034] Further, refer to Figures 3-5 As shown, it is worth noting that an active cavity 22 is formed at the end of the flaring shaft 8, and a contraction column 24 is slidably arranged in the active cavity 22. One end of the contraction column 24 passes through the flaring shaft 8 and is fixedly connected to the flaring plug 9. A return spring 26 is arranged between the other end of the contraction column 24 and the innermost inner wall of the active cavity 22.

[0035] The flaring shaft 8 is equipped with a contact component that cooperates with the flaring plug 9. The contact component is a pressure sensor 21. A mounting groove 20 for accommodating the pressure sensor 21 is provided on the outer wall of the flaring shaft 8. A through-shrinkage hole 23 communicating with the mounting groove 20 is also provided on the innermost inner wall of the active cavity 22. A pressure column 25 is slidably provided in the through-shrinkage hole 23. One end of the pressure column 25 corresponds to the pressure sensor 21, and the other end of the pressure column 25 passes through a reset spring 26 and is fixedly connected to the contraction column 24.

[0036] An alarm 19 is installed on the back panel 2;

[0037] By setting the reversing component, the contact component and the alarm 19, when the electric cylinder 15 is started and the advancing frame 4 is pushed toward the pipe clamping tool 3, the flaring plug 9 contacts the end of the pipe in advance and is forced to retract toward the side of the traveling frame 4, and then the retraction column 24 retracts the inner side of the movable chamber 22 and acts on the pressure column 25 to touch the pressure sensor 21, so that the pressure sensor 21 is pressurized to send a signal to the reversing component to record the current position, so that after the flaring of the flaring plug 9 is completed, the reversing component acts on the movable seat 5 to move to the specified position, so that the product joint 7 and the pipe end are aligned, ensuring the accuracy of the connection between the product joint 7 and the pipe end and avoiding errors. If the flaring plug 9 is not obstructed after feeding and plugging, the pressure sensor 21 is not pressed, and then it is determined that no pipe is placed in the pipe clamping tool 3 or the diameter of the placed pipe is too large, and the alarm 19 is activated to sound an alarm to the outside so that manual inspection is timely.

[0038] In addition, the flaring plug 9 is obstructed when inserted into the end of the pipe, causing the shrinkage column 24 to shrink the inner side of the active cavity 22. During this process, the shrinkage column 24 can simultaneously compress the reset spring 26 to deform. When the flaring plug 9 completes the expansion and withdraws from the end of the pipe, the shrinkage column 24 can quickly reset the flaring plug 9 under the elastic force of the reset spring 26, which is convenient for secondary use.

[0039] Further, refer to Figure 3 As shown, it is worth noting that the reversing component includes a linear servo motor 10 installed laterally below the vertical surface of the traveling frame 4, and a slider 11 assembled and connected with the movable seat 5 is slidably provided on the linear servo motor 10. A first guide rail 12 is also fixed laterally above the vertical surface of the traveling frame 4, and a first slide 13 fixedly connected with the movable seat 5 is slidably provided on the first guide rail 12;

[0040] The pressure sensor 21 is electrically connected to the linear servo motor 10 and the alarm 19 through the PLC controller;

[0041] When the flaring plug 9 contacts the end of the pipe during its movement, the action pressure column 25 touches the pressure sensor 21. The pressure sensor 21 is pressurized and sends a signal to the linear servo motor 10, so that the linear servo motor 10 records the current position. When the flaring plug 9 is started after flaring is completed, the action slider 11 carries the movable seat 5 to the position so that the product joint 7 is aligned with the pipe end.

[0042] During the sliding process of the movable seat 5 , the first slide 13 can slide synchronously on the first guide rail 12 , so that the first guide rail 12 cooperates with the first slide 13 to define the moving trajectory of the movable seat 5 , thereby ensuring the smooth movement of the movable seat 5 .

[0043] Further, refer to Figure 5As shown, it is worth mentioning that the outer wall of the end of the flared shaft 8 is symmetrically provided with a waist-shaped hole slot communicating with the movable cavity 22, one of the waist-shaped hole slots is provided with a locking screw rod 27, the locking screw rod 27 penetrates the contraction column 24 and is outwardly threaded from the other waist-shaped hole slot, the locking screw rod 27 is externally provided with a locking nut 28 abutting against the shaft body of the flared shaft 8;

[0044] Through the arrangement of the locking screw rod 27, the locking nut 28 and the waist-shaped hole slot, when the flared plug 9 is blocked in the insertion process, the locking screw rod 27 can be synchronously slid in the waist-shaped hole slot during the contraction of the contraction column 24 inside the movable cavity 22, thereby reducing the movement resistance of the flared plug 9, in addition, only a simple knob is needed to lock the locking nut 28, so that the locking nut 28 is pushed out of the shaft body of the locking screw rod 27 under the threaded structure, and the locking screw rod 27 is pulled out of the flared shaft 8, that is, the flared plug 9 can be quickly replaced when it is worn out.

[0045] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
