One side of the first heat shield 12 is fixedly connected to the first jig body 11, and the other side of the first heat shield 12 is fixedly connected to the first fixed plate 13. The first heat shield 12 is used to insulate the first jig body 11 from the first fixed plate 13. The first driver 14 of this embodiment is preferably a cylinder. The cylinder body of the first driver 14 is fixedly connected to the top of the installation box 6, and the piston rod of the first driver 14 is fixedly connected to the first fixed plate 13. The first driver 14 is used to drive the first fixed plate 13 to move up and down in the vertical direction. Three heating rods 5 are inserted at intervals in the first jig body 11 of this embodiment to heat the first jig body 11.

[0029] The second jig assembly 2 includes a second jig body 21, a second heat shield 22, and a second fixing plate 23. The bottom surface of the first jig body 11 is arranged toward the top surface of the second jig body 21. One side of the second heat shield 22 is fixedly connected to the second jig body 21, and the other side of the second heat shield 22 is fixedly connected to the second fixing plate 23.

[0033] Furthermore, if Figure 4As shown, in this embodiment, two first limiting grooves 112 and two second limiting grooves 113 are respectively defined on both sides of the bottom surface of the first jig body 11. One first limiting groove 112 and one second limiting groove 113 are respectively located at both ends of a corresponding first contoured groove 111 and are both connected to the first contoured groove 111. The first limiting groove 112 is close to the first limiting rod 33, and the second limiting groove 113 is close to the third limiting rod 43. Two third limiting grooves 212 and two fourth limiting grooves 213 are respectively defined on both sides of the bottom surface of the second jig body 21. The second jig body 21 also defines two through grooves 214 parallel to the first limiting groove 112, extending from one side close to the second limiting rod 34 to the other side. The third limiting slot 212 corresponds to the first limiting slot 112, and the fourth limiting slot 213 corresponds to the second limiting slot 113. A third limiting slot 212 and a fourth limiting slot 213 are respectively located at both ends of a corresponding second contoured slot 211 and are both connected to the second contoured slot 211.

A second limiting slot 113 and a corresponding fourth limiting slot 213 are used to accommodate the end of a third limiting rod 43. A through slot 214 is used to accommodate the end of a second limiting rod 34. Under the driving action of the second driver 35, the first limiting rod 33 is driven to extend into the first limiting groove 112 and the third limiting groove 212 at the same time until it rests against one end of the oil pipe, and the second limiting rod 34 is driven to extend into the through groove 214 until it rests against the bottom of the oil pipe; under the driving action of the third driver 44, the third limiting rod 43 is driven to extend into the second limiting groove 113 and the fourth limiting groove 213 at the same time until it rests against the other end of the oil pipe. Under the joint action of the first limiting rod 33, the second limiting rod 34 and the third limiting rod 43, the oil pipe in the accommodating groove is limited and fixed, so that the oil pipe cannot move left and right.

[0034] The following briefly describes the working process of the repair tool in this embodiment:

[0035] First, the first jig body 11 and the second jig body 21 are heated to a specified temperature using the heating rod 5. The unqualified oil pipe product is then placed in the second contoured groove 211 of the second jig body 21. The first actuator 14 then drives the first jig body 11 downward, causing the first jig body 11 and the second jig body 21 to jointly press the unqualified oil pipe. Subsequently, the second actuator 35 and the third actuator 44 move the first limiting rod 33, the second limiting rod 34, and the third limiting rod 43 until they abut the unqualified oil pipe, preventing it from moving vertically or horizontally. The unqualified oil pipe is then reheated to a fixed temperature in the holding tank to minimize stress without melting. By squeezing the first jig body 11 and the second jig body 21, any deviations from the desired geometric tolerances can be corrected, converting the unqualified oil pipe from a defective product to a qualified one.

[0036] When the specified heating time is reached, the second driver 35 and the third driver 44 respectively drive the first limiting rod 33, the second limiting rod 34 and the third limiting rod 43 to be pulled out, and the first driver 14 drives the first fixture body 11 to move up to the initial position, and the qualified oil pipe product is taken out and naturally cooled to room temperature.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention.
