The rack is meshed with the hinged end of the push rod, and its bottom surface is slidably connected with the adjustment block. The free end of the push rod is slidably connected with the adjustment plate. The design of the rack allows the push rod to move with the adjustment block when in use, and cooperates with the stationary rack, so that the free end of the push rod is lifted, and the adjustment plate is lifted by linear motion, so as to adapt to the purpose of multi-angle adaptation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Reference Figure 1-7 An angle adjustment device for expanding a three-way pipe fitting is shown, comprising a base 1, a hydraulic cylinder 2, and a power head 12. A fixed mold for fixing the three-way pipe fitting is provided in the middle of the base 1, and power heads 12 are provided in front and behind the fixed mold with the fixed mold as the center. Due to different needs of different customers, in order to be able to meet a variety of different inclination angles of the three-way pipe fitting ends, the hydraulic cylinder 2 installed on the base 1 is used to adjust the lifting height of the power head 12, so that the power head 12 can be directly adapted to the inclined end by adjusting the angle adjustment mechanism.

[0024] A fixed seat 3 is provided on the top surface of the telescopic end of the hydraulic cylinder 2. A groove 31 for installing an angle adjustment mechanism is provided on the top surface of the fixed seat 3. An adjusting rod 4 is rotatably connected in the groove 31. The adjusting rod 4 is a threaded rod, on which an adjusting block 5 is threadedly connected. The driving mechanism is connected to the adjusting rod 4, so that under the cooperation of the groove 31, the adjusting rod 4 rotates to control the adjusting block 5 to move. The cross section of the adjusting block 5 is a U-shaped piece, on which a push rod 8 is hinged. There is a gap between the push rod 8 and the top surface of the adjusting block 5, so a rack 7 is provided between the gaps, and both ends of the rack 7 are connected to the groove 31. The front and rear ends are fixed, so when the adjusting block 5 and the push rod 8 move, the rack 7 is in a stationary state. In order to control the free end of the push rod 8 to be lifted during the movement, an adjusting tooth 81 is provided at the hinged end of the push rod 8. The adjusting tooth 81 is meshed with the rack 7 to achieve the purpose of lifting the push rod 8. The lifted push rod 8 pushes the bottom surface of the adjusting plate 9 upward, and then the adjusting plate 9 takes the hinged end as the center of the circle, driving the power head 12 provided on its top surface to tilt, so that the power head 12 can adapt to the end heads with various tilt angles, thereby improving its practicality.

[0025] The auxiliary block 91 provided on the bottom surface of the adjusting plate 9 cooperates with the push rod 8 to extend the inclination angle of the adjusting plate 9 through its arc surface design.

[0026] In order to facilitate the use of the driving angle adjustment mechanism, a mounting plate 10 is hoisted on the bottom surface of the fixing seat 3. The adjustment motor 11 installed on the mounting plate 10 is connected to the end of the adjustment rod 4 through a gear set 6. The gear set 6 is a bevel gear set.

[0027] The adjusting gear 61 is coaxially arranged with the adjusting rod 4 and meshes with the driving gear 62. The two cooperate with each other, and the driving gear 62 is controlled to rotate by the adjusting motor 11, thereby driving the entire angle adjustment mechanism to start.

[0028] Working principle of the utility model: after confirming the inclination angle of the end of the three-way pipe fitting, use the corresponding fixed mold to fix the three-way pipe fitting, then start the hydraulic cylinder 2 on the base 1 to make the hydraulic cylinder 2 work, and after raising the fixed seat 3 on its telescopic end to a suitable height, start the adjustment motor 11 on the mounting plate 10, and the driving gear 62 provided on the driving shaft of the adjustment motor 11 drives the adjustment gear 61 meshed with it to rotate on the fixed seat 3, thereby driving the adjustment rod 4 coaxially arranged therewith to rotate in the groove 31, and under the limit of the groove 31, the adjustment rod 4 is threadedly connected with the adjustment block 5 to control the movement of the adjustment block 5 in the groove 31. The adjusting tooth 81 at the end of the push rod 8 is meshed with the rack 7, so that the other end of the push rod 8 is lifted and slides on the bottom surface of the adjusting plate 9, and cooperates with the auxiliary block 91 to change the adjusting plate 9, which is in a parallel relationship with the fixing seat 3, from a parallel relationship to an angle relationship, so that the power head 12 installed on the adjusting plate 9 is completed. The angle tilting is then completed, and the power head 12 works to process the end of the three-way pipe fitting. After completing the above operation, if it needs to be reset, the adjusting motor 11 is reversed, and the power head 12 presses down the adjusting plate 9 under the action of gravity to restore it to its original state.
