DETAILED DESCRIPTION

[0027] 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 belong to the scope of protection of the utility model.

[0028] like Figures 1 to 8 As shown, a quick-change pipe spinning device comprises a spinning processing head 1 and a pipe clamping die 2. The pipe clamping die 2 is used to clamp the pipe, and the pipe clamping die 2 is driven by a cylinder, and the pipe clamping die 2 corresponds to the processing head.

[0029] The spinning processing head 1 comprises a rotating disk 3, a mandrel seat 8, a mandrel 10, and a roller shaft 5. A roller 6 is rotatably connected to the roller shaft 5. A roller bearing 7 is provided between the roller 6 and the roller shaft 5. The roller 6 can be flexibly rotated on the roller shaft 5 through the roller bearing 7. A sliding seat 4 is provided on the rotating disk 3 and can move radially along the rotating disk 3. One end of the roller shaft 5 is threadedly connected to the sliding seat 4.

[0030] The roller shaft 5 is divided into a single-support roller shaft and a double-support roller shaft. The length of the double-support roller shaft is greater than that of the single-support roller shaft. The width of the roller 6 connected to the double-support roller shaft is also greater than that of the roller 6 connected to the double-support roller shaft 5. The roller 6 on the double-support roller shaft can withstand greater pressure. The roller shaft 5 is provided with a bearing mounting ring surface 20 for mounting the roller bearing 7. The roller bearing 7 is sleeved on the bearing mounting ring surface 20. The inner ring of the roller bearing 7 is interference fit with the bearing mounting ring surface 20.

[0031] A roller shaft mounting stud 21 is provided at one end of the roller shaft 5, and a roller shaft mounting screw hole matching the roller shaft mounting stud 21 is provided on the sliding seat 4; the roller shaft mounting stud 21 is threadedly connected in the roller shaft mounting screw hole. When the pipe fitting is subjected to spinning, the rotation direction of the roller 6 is consistent with the tightening direction of the ball shaft mounting stud. Since the rotation direction of the roller 6 is consistent with the tightening direction of the ball shaft mounting stud, the roller shaft 5 can be effectively prevented from loosening.

[0032] When the double-support roller shaft is installed on the sliding seat 4, a support member 18 is installed on the sliding seat 4, and the end of the double-support roller shaft away from the sliding seat 4 is supported by the support member 18. The support member 18 is connected to the sliding seat 4 through the support member 18 connecting screw. The support member 18 is provided with an axial hole, and the end of the double-support roller shaft away from the sliding seat 4 is connected to the axial hole. The support member 18 is provided with a second support member connecting screw hole 19, and the sliding seat 4 is provided with a first support member connecting screw hole 15 corresponding to the second support member connecting screw hole 19. The support member 18 connecting screw passes through the second support member connecting screw hole 19 and is connected to the first support member connecting screw hole 15 on the sliding seat 4. Further, a positioning pin 16 is provided on the sliding seat 4, and a pin hole corresponding to the positioning pin 16 is provided on the support member 18. When the support member 18 is installed, the support member 18 is positioned by the cooperation between the positioning pin 16 and the pin hole.

[0033] Since the double-support roller shaft is relatively long, when one end of the double-support roller shaft is mounted on the sliding seat 4, the other end of the double-support roller shaft will bend due to the overhanging length; in the present invention, by installing the support member 18 and supporting the end of the double-support roller shaft, the bending degree of the double-support roller shaft can be effectively reduced. The single-support roller shaft itself is relatively short, so when installing the single-support roller shaft, there is no need to install the support member 18 for support.

[0034] The mandrel seat 8 is rotatably connected to the center of the rotating disk 3. A mandrel seat bearing 9 is provided between the mandrel seat 8 and the rotating disk 3. The mandrel seat 8 can be flexibly rotated around its own central axis through the mandrel seat bearing 9. The mandrel 10 is detachably connected to the mandrel seat 8.

[0035] Among them, the mandrel seat 8 is provided with a mandrel mounting screw hole 22, and one end of the mandrel 10 is provided with a mandrel mounting stud 23 that matches the mandrel mounting screw hole 22; a tightening screw hole 24 is provided on one side of the mandrel mounting screw hole 22, and the mandrel tightening screw 12 is connected in the tightening screw hole 24; the mandrel mounting stud 23 is provided with a tightening groove 13 corresponding to the mandrel tightening screw 12. When installing the mandrel 10, it is only necessary to screw the mandrel mounting stud 23 on the mandrel 10 into the mandrel mounting screw hole 22 on the mandrel seat 8. After the mandrel 10 is tightened and the tightening groove 13 on the mandrel 10 is aligned with the tightening screw hole 24, the mandrel tightening screw 12 in the tightening screw hole 24 is tightened so that the front end of the mandrel tightening screw 12 presses against the mandrel mounting stud 23.

[0036] A spanner connector 25 is provided at one end of the mandrel 10 away from the mandrel mounting stud 23. The spanner connector 25 has a rectangular or regular hexagonal cross section and can be connected to a spanner through the spanner connector 25. The spanner connector 25 plays a role in transmitting torque, making it convenient to install and tighten the mandrel 10 through a spanner.

[0037] The rotating disk 3 is provided with an oil spraying component 11; when the pipe is spun, the oil spraying component 11 sprays oil on the surface of the roller 6. The following benefits can be achieved by spraying oil on the outer surface of the roller 6: 1. The surface of the roller 6 can be cooled; 2. The roller 6 and the outer surface of the pipe can be lubricated.

[0038] The utility model has the following advantages:

[0039] 1. The utility model can conveniently install and disassemble the roller shaft 5 and the mandrel 10, thereby facilitating the replacement of the roller 6 and the mandrel 10. The required roller 6 and mandrel 10 can be conveniently replaced according to different processing requirements, which greatly shortens the changeover time and is conducive to improving production efficiency.

[0040] 2. In view of the problem that the double-support roller shaft is relatively long and prone to overhang bending, the utility model supports the end of the double-support roller shaft through the support member 18 when installing the double-support roller shaft, which effectively reduces the bending of the double-support roller shaft, thereby improving the spinning processing accuracy.

[0041] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
