Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0048] Example 1

[0049] like Figure 1-Figure 5 As shown, this embodiment provides a high-speed cutting device for stainless steel pipes, including: a base 1, a clamping assembly 4, a top frame 5, a cutting assembly 6, a position adjustment assembly 7, a lifting assembly 9, a gear seat 10,

A positioning hole 201 is opened in the middle of the positioning seat 2 for the pipe 100 to pass through. The aperture of the positioning hole 201 is larger than the diameter of the pipe 100. The end positioning member 3 is provided on one side of the positioning seat 2 in the axial direction of the positioning hole 201. When positioning, one end of the pipe 100 passes through the positioning hole 201 and abuts against the end positioning member 3.

[0051] See also Figure 1 The clamping assembly 4 is provided on a side of the middle positioning member away from the end positioning member 3. The clamping assembly 4 can clamp the pipe 100. The clamping assembly 4 can be selected from components in the prior art. The components for clamping the pipe 100 in this field are well known to those skilled in the art and will not be described in detail herein.

[0052] The top frame 5 is L-shaped, the vertical section of the top frame 5 is connected to the base 1, and the horizontal section of the top frame 5 is located above the base 1;

[0053] The cutting assembly 6 includes a cutting blade 601 and a power source 602. The power source 602 is used to drive the cutting blade 601 into a cutting state. The power source 602 is generally a motor. The cutting blade 601 and the power source 602 can also be commercially available components.

[0054] The position adjustment component 7 is used to adjust the horizontal position of the cutting component 6. In this embodiment, the position adjustment component 7 includes: a horizontal axis 701, a horizontal displacement seat 702, a vertical axis 703, and a vertical displacement seat 704.

[0055] The two ends of the horizontal shaft 701 are horizontally connected to the horizontal section of the top frame 5; a first through hole is opened on the transverse seat 702, and the transverse seat 702 is slidably mounted on the transverse shaft 701 through the first through hole. The transverse seat 702 can slide along the axial direction of the transverse shaft 701. Figure 1 There are two transverse shafts 701, which are distributed in parallel. Correspondingly, two transverse seats 702 are also provided. Each transverse seat 702 cooperates with one transverse shaft 701, and there is sufficient clearance between the two transverse seats 702.

[0056] The two ends of the longitudinal axis 703 are horizontally connected to the two transverse movement seats 702, and the longitudinal axis 703 is perpendicular to the transverse axis 701. A second through hole is opened on the longitudinal movement seat 704, and the longitudinal movement seat 704 is slidably sleeved on the longitudinal axis 703 through the second through hole. The longitudinal movement seat 704 can slide along the axial direction of the longitudinal axis 703. The lifting assembly 9 is arranged at the bottom of the longitudinal movement seat 704.

[0057] In this embodiment, the sliding cooperation between the transverse movement seat 702 and the transverse shaft 701, and the sliding cooperation between the longitudinal movement seat 704 and the longitudinal shaft 703 can generate a certain friction force, so that after the transverse movement seat 702 and the longitudinal movement seat 704 are moved to the appropriate position, the transverse movement seat 702 and the longitudinal movement seat 704 will not move without external force.

[0058] The lifting assembly 9 is used to drive the cutting assembly 6 to move closer to and away from the pipe 100. In this embodiment, please refer to Figure 1 The lifting assembly 9 includes a lifting cylinder 901, which is mounted on the longitudinal displacement seat 704. The output rod 902 at the bottom of the lifting cylinder 901 is provided with a mounting seat 903. The cutting assembly 6 is mounted on the mounting seat 903. When the lifting cylinder 901 is activated, it can drive the output rod 902 to move vertically, thereby driving the mounting seat 903 to move up and down, thereby driving the cutting assembly 6 to move up and down.

[0059] See also Figure 6 The gear seat 10 is provided on the top frame 5. The gear seat 10 can locate the final position of the position adjustment assembly 7. In this embodiment, the gear seat 10 is L-shaped. The gear seat 10 can fit with the two adjacent side walls of the longitudinal movement seat 704, thereby locating the final position of the longitudinal movement seat 704.

[0060] In this embodiment, the middle of the pipe fitting 100 is positioned by the middle positioning piece, and the end of one end of the pipe fitting 100 is positioned by the end positioning piece 3, and then the positioned pipe fitting 100 is clamped by the clamping assembly 4, and then the gear seat 10 is adjusted to a suitable position according to the required cutting length, and then the cutting assembly 6 is adjusted to the cutting position by the position adjustment assembly 7, and the power source 602 drives the cutting blade 601 to enter the cutting state, and the lifting assembly 9 drives the cutting assembly 6 close to the pipe fitting 100, so that the cutting blade 601 contacts the pipe fitting 100 to cut the pipe fitting 100.

[0061] In this embodiment, the structure of the pipe 100 is clamped. Figure 4 and Figure 5 .

[0062] Example 2

[0063] This embodiment provides a high-speed cutting device for stainless steel pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0064] See also Figure 1 A retreat groove 101 is opened on the base 1 along the radial direction of the pipe 100, and the end positioning member 3 is horizontally slidably connected to the retreat groove 101. The end positioning member 3 can approach and move away from the axis of the pipe 100 in the radial direction of the pipe 100.

[0065] In this embodiment, Figure 1 What is shown is the situation where the power source 602 is located on the side away from the end positioning member 3. During the actual assembly process, the power source 602 may also be installed in other directions. In this embodiment, the end positioning member 3 is designed to be positionally adjustable in the radial direction of the pipe 100. In this way, after the pipe 100 is clamped by the clamping assembly 4, the end positioning member 3 can be away from the pipe 100, leaving enough space near the end of the pipe 100, and the cutting assembly 6 will not interfere with the end positioning member 3 during operation.

[0066] Example 3

[0067] This embodiment provides a high-speed cutting device for stainless steel pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0068] The difference from Example 1 is that in this embodiment, the sliding fit between the transverse seat 702 and the transverse shaft 701, and the sliding fit between the longitudinal seat 704 and the longitudinal shaft 703 are smooth, which can reduce the difficulty of operation for workers. In addition, a locking assembly 8 is provided on both the transverse seat 702 and the longitudinal seat 704. The locking assembly 8 is used to lock the transverse seat 702 in its current position on the transverse shaft 701, and to lock the longitudinal seat 704 in its current position on the longitudinal shaft 703.

[0069] Specific examples Figure 7 and Figure 8 As shown, the positioning assembly 8 includes: a mounting plate 801, two clamping plates 802, a bidirectional screw 803, a rotary rod 804,

[0070] See also Figure 7 , the mounting plate 801 is provided on the transverse movement seat 702 or the longitudinal movement seat 704; two card plates 802 are slidably provided on the mounting plate 801, with a spacing between the two card plates 802, and two coaxial screw holes 8021 are provided on the two card plates 802;

[0071] The bidirectional screw 803 passes through the two screw holes 8021 in sequence. Figure 8 , two opposite external threads are respectively formed at both ends of the bidirectional screw 803, and the two external threads are respectively threadedly connected to the two screw holes 8021; the rotating rod 804 is provided at the end of the bidirectional screw 803 for rotating the bidirectional screw 803;

[0072] Taking the transverse shift seat 702 as an example, the two clamping plates 802 are respectively located on both sides of the transverse axis 701. When the transverse shift seat 702 needs to be moved, the worker applies a rotational force to the rotary rod 804 to drive the bidirectional screw 803 to rotate, so that the two clamping plates move away from the transverse axis 701. At this time, the transverse shift seat 702 can be easily moved; after the transverse shift seat 702 moves to the appropriate position, the worker applies a rotational force to the rotary rod 804 to drive the bidirectional screw 803 to rotate, so that the two clamping plates move toward each other to clamp the transverse axis 701. At this time, the sliding of the transverse axis 701 seat on the transverse axis 701 is restricted, thereby improving the stability of the pipe fitting 100 during the cutting process.

[0073] Example 4

[0074] This embodiment provides a high-speed cutting device for stainless steel pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0075] See also Figure 3 An adjustment seat 11 is provided on the top frame 5, and an adjustment rod 12 is provided on the end of the gear seat 10 away from the longitudinal movement seat 704. The adjustment rod 12 can adjust the horizontal position of the gear seat 10 on the adjustment seat 11. The horizontal position here refers to the position in the axial direction of the pipe 100. By adjusting the horizontal position of the gear seat 10, it can adapt to the cutting requirements of pipes of different lengths 100, making the cutting device more applicable.

[0076] 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.
