[0035] Pipe fittings 100

[0036] The pipe fitting 100 in the present invention includes a workpiece with a tubular structure such as a stainless steel pipe.

[0037] Example 1

[0038] like Figure 1-Figure 3 As shown, this embodiment provides a cutting and clamping structure for stainless steel pipes, including: a base, a positioning seat 1, a clamping plate 2, an end clamping seat 3, a clamping plate 4,

[0039] See also Figure 1, a positioning groove is provided on the upper surface of the positioning seat 1, and the positioning groove is arc-shaped and is used to position the pipe 100;

[0040] The clamping plate 2 is provided on one side of the positioning seat 1. In this embodiment, the clamping plate 2 is provided above the positioning seat 1. The pipe fitting 100 is placed between the positioning seat 1 and the clamping plate 2. The clamping plate 2 can be raised and lowered relative to the positioning seat 1 to move closer to and away from the positioning seat 1, thereby cooperating with the positioning seat 1 to clamp and release the pipe fitting 100.

[0041] As a preferred embodiment of this invention, please refer to Figure 1 A fixing frame 6 is provided on one side of the positioning seat 1, and the splint 2 is connected to the fixing frame 6 by sliding in the vertical direction. The splint 2 approaches and moves away from the positioning seat 1 during the sliding process. A first threaded hole 7 is opened on the upper end of the fixing frame 6 in the vertical direction. A first screw rod 8 is threadedly connected to the first threaded hole 7. One end of the first screw rod 8 is rotatably connected to the splint 2. When the first screw rod 8 is rotated, the first screw rod 8 will perform a vertical spiral motion relative to the fixing frame 6. In this process, the first screw rod 8 will lift and lower the splint 2 on the fixing frame 6.

[0042] The end clamping seat 3 is located on one side of the positioning seat 1, and the base is used to support the positioning seat 1, the fixing seat and the end clamping seat 3;

[0043] See also Figure 2 The clamping disc 4 is rotatably mounted on the end clamping seat 3. The clamping disc 4 is coaxially distributed with the pipe 100. The clamping disc 4 is provided with a plurality of abutment blocks 5 which can be adjusted in the radial direction of the clamping disc 4. The plurality of abutment blocks 5 are spaced apart along the circumference of the clamping disc 4. One end of the abutment block 5 extends out from the clamping disc 4;

[0044] The end of the pipe 100 can be sleeved on the outside of the clamping plate 4 and the abutment block 5, and the plurality of abutment blocks 5 can be tightly abutted against the inner wall of the pipe 100 to clamp the end of the pipe 100;

[0045] Figure 3 A schematic diagram of the clamping structure of this embodiment clamping a pipe 100 is shown. The clamping plate 2 cooperates with the positioning seat 1 to clamp the outer wall of one end of the pipe 100, and the clamping plate 4 cooperates with the plurality of abutment blocks 5 to clamp the inner wall of the other end of the pipe 100.

[0046] In this embodiment, the clamping structure and the cutting structure (not shown in the figure) are used in combination to clamp and cut the pipe fitting 100. The cutting structure can adopt the structure in the prior art. The cutting structure is located between the positioning seat 1 and the end clamping seat 3. When clamping the pipe fitting 100, the pipe fitting 100 is first placed on the positioning seat 1 for positioning, and one end of the pipe fitting 100 is sleeved on the outside of the clamping disk 4 and the abutment block 5. Then, one end of the pipe fitting 100 is clamped by cooperating with the clamping plate 2 and the positioning seat 1, and then the radial position of the multiple abutment blocks 5 on the clamping disk 4 is adjusted so that the multiple abutment blocks 5 are tightly against the inner wall of the pipe fitting 100, thereby clamping the end of the free end of the pipe fitting 100. At this time, the cutting structure is started to cut the pipe fitting 100.

[0047] Example 2

[0048] This embodiment provides a cutting and clamping structure for stainless steel pipes. In addition to the technical solutions of the above embodiments, the clamping structure is also optimized.

[0049] See also Figure 1 In this embodiment, an adjustment seat 9 is provided on the end clamping seat 3 so as to slide in the vertical direction, and the clamping disk 4 is rotatably provided on the adjustment seat 9. A second threaded hole 10 is provided on the upper end of the end clamping seat 3 in the vertical direction. A second screw 11 is threadedly connected to the second threaded hole 10. One end of the second screw 11 is connected to the adjustment seat 9. When the second screw 11 is rotated, the second screw 11 will perform a vertical spiral motion relative to the end clamping seat 3. In this process, the second screw 11 will bring the adjustment seat 9 to adjust the vertical position on the end clamping seat 3, thereby adjusting the vertical position of the clamping disk 4.

[0050] Through the technical solution of this embodiment, when clamping pipes 100 of different diameters, the clamping disk 4 can be adjusted to be coaxial with the pipe 100, thereby effectively clamping the inner wall of the pipe 100, thereby improving the applicability of the clamping structure of the embodiment.

[0051] Example 3

[0052] This embodiment provides a cutting and clamping structure for stainless steel pipes. In addition to the technical solutions of the above embodiments, it also discloses a method for adjusting the position of the abutment block 5 on the clamping plate 4.

[0053] See also Figure 4 The abutment block 5 is connected to the clamping disk 4 by sliding along the radial direction. The clamping disk 4 is coaxially provided with an adjusting wheel 12. The outer peripheral wall of the adjusting wheel 12 is provided with multiple groups of protrusions 13. One end of the protrusion 13 is spaced from the other end in the radial direction of the adjusting wheel 12, so that one end of the protrusion 13 is the proximal point of the center of the adjusting wheel 12, and the other end of the protrusion 13 is the distal point of the center of the adjusting wheel 12. One end of the protrusion 13 is smoothly connected to the other end. Please refer to Figure 5The outer surface of the raised portion 13 is an arc-shaped inclined surface, and each group of raised portions 13 corresponds to an abutment block 5, and the end of the abutment block 5 close to the adjusting wheel 12 is connected to the raised portion 13;

[0054] For details, please refer to Figure 5 , one end of the abutment block 5 close to the adjusting wheel 12 contacts the protrusion 13, an elastic member 14 is provided between the abutment block 5 and the clamping disk 4, a first mounting block 1501 is provided on the clamping disk 4, and a second mounting block 1502 is provided on the abutment block 5. The two ends of the elastic member 14 are respectively connected to the first mounting block 1501 and the second mounting block 1502. When the abutment block 5 is pushed toward the outside of the clamping disk 4, the elastic member 14 is deformed;

[0055] In this embodiment, changing the angle of the adjusting wheel 12 can change the position of the contact point between the abutment block 5 and the protrusion 13. In the process of the contact point between the abutment block 5 and the protrusion 13 moving from the proximal point to the distal point, the abutment block 5 is pushed toward the outside of the clamping disk 4, and the elastic member 14 is stretched during this process; in the process of the contact point between the abutment block 5 and the protrusion 13 moving from the distal point to the proximal point, a short gap appears between the abutment block 5 and the protrusion 13. At this time, the elastic force of the elastic member 14 drives the abutment block 5 to move toward the inside of the clamping disk 4, so that the abutment block 5 is always in contact with the protrusion 13.

[0056] As a preference of this embodiment, the end surface of the abutment block 5 away from the adjusting wheel 12 is arc-shaped, which can increase the contact area between the abutment block 5 and the inner wall of the pipe 100 and improve the clamping effect of the abutment block 5 on the inner wall of the pipe 100.

[0057] Example 4

[0058] This embodiment provides a cutting and clamping structure for stainless steel pipes. In addition to the technical solutions of the above embodiments, it also discloses a method for adjusting the angle of the adjusting wheel 12.

[0059] In this embodiment, please refer to Figure 1 , a main shaft 16 is coaxially provided on the adjusting wheel 12, and the main shaft 16 extends to the outside of the end clamping seat 3, and the main shaft 16 is used to drive the adjusting wheel 12 to rotate;

[0060] In this embodiment, the worm gear 17 and worm 18 drive the main shaft 16 to adjust the angle. For details, please refer to Figure 6 , a worm gear 17 is provided on the main shaft 16, and a worm 18 is provided on the end clamping seat 3. The worm 18 is connected to the worm gear 17. Rotating the worm 18 can drive the worm gear 17 to rotate, thereby driving the main shaft 16 to adjust the angle;

[0061] The advantages of the worm wheel 17 and worm 18 are that they are self-locking and have a large reduction ratio. The self-locking property means that only the worm 18 can drive the worm wheel 17 to rotate, while the worm wheel 17 cannot drive the worm 18 to rotate, which can ensure the overall stability of the clamping structure after the clamping structure clamps the pipe 100; the large reduction ratio means that when the worm 18 is rotated at a large angle, the worm wheel 17 will only rotate a small angle, which makes it easy to fine-tune the position of the abutment block 5 and achieve precise clamping of the inner wall of the pipe 100.

[0062] The embodiments of the present invention are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
