[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0022] Combination Figure 1-3 As shown, the automotive air conditioning pipe processing equipment includes a base 1, a main body 2 mounted on the base 1, a pipe expander 3 mounted at the front end of the main body 2, and a hydraulic cylinder 4 for driving the pipe expander 3 to expand.
[0023] The main body 2 is provided with a through hole, and a sliding sleeve 5 is provided at the rear end of the through hole. A push rod 6 is slidably connected to the sliding sleeve 5. An arm 7 is sway-connected to the rear end of the seat body 1. A waist hole is provided at the upper end of the arm 7. The rear end of the push rod 6 is slidably connected to the waist hole through a connecting rod 8. The hydraulic cylinder 4 is sway-connected to the bottom of the seat body 1. The piston rod of the hydraulic cylinder 4 is rotatably connected to the lower end of the arm 7.
[0024] The expansion head 3 includes multiple sector blocks 9, each sector block 9 having an expansion section 10 at its front end. The front end of the main body 2 is provided with a circular mounting groove, which is connected to a through hole. Each sector block 9 is radially extended and retracted within the mounting groove.
[0025] When the push rod 6 is inserted between the sector blocks 9, each sector block 9 moves outward from the mounting groove, thereby expanding the tube head 3; when the push rod 6 is pulled out from between the sector blocks 9, each sector block 9 returns to its original disc shape, thereby shrinking the tube head 3; when the tube head 3 shrinks, each of the tube expansion sections 10 abuts against each other to form a column.
[0026] The working principle of the above structure is as follows: Initially, the expander head 3 is in a contracted state, and the end of the automotive air conditioning pipe is aligned with the column composed of each expander section 10, with the column being fitted inside. Then, the hydraulic cylinder 4 is activated, causing the lower end of the arm 7 to swing backward toward the seat 1. The arm 7 drives the push rod 6 to slide forward, and the front end of the push rod 6 is inserted between each sector block 9 until the front end of the push rod 6 is flush with the front end of each expander section 10. At this time, each sector block 9 and the expander section 10 open under the action of the push rod 6, thereby realizing the expansion of the end of the automotive air conditioning pipe. After the expansion is completed, the push rod 6 is reset, and each sector block 9 and the expander section 10 retracts, allowing the end of the automotive air conditioning pipe to be easily removed from the expander head 3, completing the processing.
[0027] The advantages of the above structure are: it is simple and compact in construction, occupies little space, and has low manufacturing cost. By using the lever principle to push the sliding of the push rod 6, it can realize the rapid expansion of the end of the automotive air conditioning pipe.
[0028] In another embodiment, combined Figure 1-3 As shown, the base 1 is composed of a base plate 11 and wall panels 12 respectively disposed on both sides of the base plate 11.
[0029] In another embodiment, combined Figure 1 and Figure 2 As shown, the arm body 7 is composed of a left arm body and a right arm body. The middle and lower ends of the left arm body and the right arm body are connected by a first connecting shaft 13 and a second connecting shaft 14, respectively. The piston rod of the hydraulic cylinder 4 is rotatably connected to the second connecting shaft 14.
[0030] In another embodiment, a connecting seat is provided on the inner side of each of the two wall panels 12, and the two ends of the first connecting shaft 13 pass through the left arm body 7 and the right arm body 7 respectively and are rotatably connected to the corresponding connecting seat, so as to avoid the first connecting shaft 13 being too long and thus having insufficient strength.
[0031] In another embodiment, combined Figure 1 and Figure 2 As shown, the distance between the waist hole and the first connecting shaft 13 is smaller than the distance between the second connecting shaft 14 and the first connecting shaft 13, so as to achieve a lever effect.
[0032] Optionally, the arm 7 is a straight arm.
[0033] Optionally, the arm 7 is a curved arm.
[0034] In another embodiment, combined Figure 1 and Figure 2 As shown, the lower end of the main body 2 is also provided with a corresponding clearance part for the hydraulic cylinder 4 to avoid affecting the swing of the hydraulic cylinder 4.
[0035] In another embodiment, combined Figure 1-3 As shown, the base 1 is also provided with a support 15 corresponding to the main body 2. The bottom of the main body 2 abuts against the support 15. The two sides of the main body 2 are respectively fixed to the two wall panels 12 by fixing bolts to ensure the reliability of the main body 2 and prevent displacement.
[0036] In another embodiment, combined Figure 1 and Figure 2 As shown, each of the sector blocks 9 has a chamfer at its rear end, and the front end of the push rod 6 is shaped like a frustum of a cone, so that the push rod 6 can be inserted between the sector blocks 9.

[0038] In another embodiment, combined Figure 1-3 As shown, a disc body 16 is fixed at the front end of the main body 2, the mounting groove is disposed in the disc body 16, and each of the sector blocks 9 is disposed on the disc body 16 to facilitate the assembly of each sector block 9.
