Therefore, the direction word does not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, and only has a relative limiting effect.

[0035] The utility model provides a kind of high-pressure oil pipe flaring machine, such as Figures 1 to 9As shown, it comprises a rack 01, a clamp 04 fixedly connected to the rack 01, a rotary power device 02 slidingly connected to the rack 01, a feeding mechanism 03 for driving the rotary power device 02 to approach and move away from the clamp 04, and a machining assembly 06 rotated by the rotary power device 02, wherein the machining assembly 06 comprises a rotary head 1 and a flaring head 2, the rotary head 1 is rotated by the rotary power device 02, the flaring head 2 is installed at a non-circular center position of the rotary head 1, the flaring head 2 is in the shape of a circular truncated cone and a part of the outer surface of the flaring head 2 forms a flaring camber surface 21, the flaring head 2 is further provided with a through hole 23 penetrating through the flaring head 2, the through hole 23 is perpendicular to the outer surface of the flaring head 2, a milling block 3 is slidingly connected in the through hole 23, a first end of the milling block 3 is provided with a milling cutter 31 and the first end can extend out of the outer surface of the flaring head 2, and the flaring head 2 is further connected with a abutting mechanism for abutting the milling block 3 and making the milling block 3 tend to extend out of the outer surface of the flaring head 2; the flaring head 2 can be installed at the rotary head 1 in a first state and a second state, the outer side of the area crossed by the flaring head 2 when the machining assembly 06 rotates is a working surface, the flaring camber surface 21 is located at the working surface in the first state, and the milling cutter 31 is located at the working surface in the second state.

[0036] Based on the above structure, the high-pressure oil pipe flaring machine first sets the machining assembly 06 in the first state to machine the flaring structure 71 on the high-pressure oil pipe 05, then sets the machining assembly 06 in the second state and makes the flaring head 2 closely contact the flaring structure 71, under the action of the abutting mechanism, the milling block 3 tends to extend out of the outer surface of the flaring head 2, that is, the milling cutter 31 will exert force on the flaring structure 71, then the machining assembly 06 is continuously rotated by the rotary power device 02 after being re-rotated, the milling cutter 31 mills the annular positioning structure 72 on the flaring structure 71, and the annular positioning structure 72 extends in the thickness direction of the flaring structure 71, which is good for the positioning effect of the subsequently installed sealing ring.

[0037] In the embodiment, the abutting mechanism comprises a spring 4, an abutting block 5 and an abutting screw 6; the length of the milling block 3 is less than the length of the through hole 23, the milling block 3, the spring 4, the abutting block 5 and the abutting screw 6 are sequentially arranged in the through hole 23 from the first end to the second end of the through hole 23, the milling block 3 and the abutting block 5 are both slidingly connected in the through hole 23, and the abutting screw 6 is screwed at the second end of the through hole 23; when the abutting screw 6 is screwed into the through hole 23, the spring 4 is compressed and the spring 4 abuts the milling block 3 to tend to extend out of the outer surface of the flared head 2. Based on the above structure, before the annular positioning structure 72 is processed, the rotary power device 02 is in a stopped state, the abutting screw 6 is loosened by the worker to make the milling block 3 retract into the through hole 23, and then the rotary power device 02 is pushed by the feeding mechanism 03 to make the flared head 2 again abut against the flared structure 71, and then the abutting screw 6 is screwed by the worker, at this time the spring 4 is compressed and provides a rebound force, under the action of the rebound force, the milling block 3 tends to extend out of the through hole 23, at this time the rotary power device 02 is started to make the processing assembly 06 rotate, and the milling cutter 31 continuously scrapes the inner surface of the flared structure 71 in the process of the rotation of the processing assembly 06, and the scraping is deeper and deeper until the annular positioning structure 72 is formed; finally, after the rotary power device 02 is stopped, the abutting screw 6 is screwed out, the milling block 3 is retracted, and the flared head 2 is withdrawn from the high-pressure oil pipe 05.

[0038] In the embodiment, the through hole 23 is provided with a sliding groove 231, the milling block 3 is provided with a first sliding block 32, the abutting block 5 is provided with a second sliding block 51, and the first sliding block 32 and the second sliding block 51 are both slidingly connected in the sliding groove 231. Based on the above structure, the cooperation of the first sliding block 32 and the second sliding block 51 with the sliding groove 231 can make the milling block 3 and the abutting block 5 slide smoothly, and can prevent the milling block 3 from rotating, thereby ensuring the accuracy of the position of the milling cutter. Preferably, the sliding groove 231 is communicated to the outside from the second end of the through hole 23 and is blocked at the first end of the through hole 23. Based on the above structure, the milling block 3, the spring 4 and the abutting block 5 are sequentially loaded into the through hole 23 from the second end of the through hole 23, and the milling block 3 is limited by the blocking structure and cannot fall out of the through hole 23, which can also prevent the milling block 3 from cutting too deep.

[0040] In this embodiment, the rotating head 1 is provided with a socket, and the flaring head 2 has a plug 22 at its position. The plug 22 is inserted into the socket to mount the flaring head 2 onto the rotating head 1. This structure allows for quick and convenient installation and removal of the flaring head 2 from the rotating head 1. Preferably, the rotating head 1 is provided with a first positioning hole 12 extending from the outside to the socket 11, and the plug 22 is provided with at least two circumferentially distributed second positioning holes 221. A positioning screw 13 passes through the first positioning hole 12 and is screwed into the second positioning hole 221. When the first positioning hole 12 is aligned with one of the second positioning holes 221, the flaring head 2 is mounted on the rotating head 1 in a second state; when the first positioning hole 12 is aligned with the other second positioning hole 221, the flaring head 2 is mounted on the rotating head 1 in a first state. Based on the above structural design, the installation angle of the flaring head 2 can be quickly positioned to switch states. More preferably, the insert rod 22 is provided with four circumferentially distributed second positioning holes 221; when the first positioning hole 12 is opposite to one of the second positioning holes 221, the flaring head 2 is installed in the rotating head 1 in a second state; when the first positioning hole 12 is opposite to the other three second positioning holes 221, the flaring head 2 is installed in the rotating head 1 in a first state. Based on the above structural configuration, when the flaring arc surface 21 at one angle of the flaring head 2 is severely worn, it can be rotated to another angle, and another section of the flaring arc surface 21 can be used for flaring, thus extending the service life of the flaring head 2; as for the milling block 3, the milling cutter can be replaced after wear, so only one second positioning hole 221 needs to be matched for it.

[0041] In summary, this type of high-pressure oil pipe flaring machine can complete the flaring and processing of the annular positioning structure 72, and the high-pressure oil pipe 05 it produces is as follows: Figure 10 As shown, the flaring structure 71 and the annular positioning structure 72 can improve the sealing performance of the sealing joint composed of this type of high-pressure oil pipe 05. Furthermore, this high-pressure oil pipe flaring machine has a simple structure, low manufacturing cost, and is easy to operate.
