[0029] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-8This invention provides a technical solution: a cutting device for processing nickel-titanium alloy tubes, comprising a cutting device body 1; an adjustment mechanism 2 is installed on the upper end of the cutting device body 1, a support base 3 is fixedly installed on the upper end of the adjustment mechanism 2, a fixed sleeve 4 is rotatably connected to the inner wall of the upper end of the support base 3, a round tube clamping mechanism 5 is fixedly connected to one end of the inner side of the fixed sleeve 4, the round tube clamping mechanism 5 is used to clamp the nickel-titanium alloy tube, an electric telescopic rod 7 is fixedly connected to the outer surface of the end of the fixed sleeve 4 away from the round tube clamping mechanism 5, and a mounting round plate is fixedly connected to the outer surface of the piston rod at the output end of the electric telescopic rod 7. 8. The mounting circular plate 8 has a cross-shaped plate structure. A connecting frame plate 9 is movably connected to the other side of the mounting circular plate 8. A convenient assembly mechanism is provided between the mounting circular plate 8 and the connecting frame plate 9. A circular tube top support mechanism is installed at the end of the connecting frame plate 9 away from the mounting circular plate 8 for pressing against the inner wall of the nickel-titanium alloy tube. A drive assembly is provided on the outer surface of the support base 3. The drive assembly includes a drive motor 6, which is fixedly installed on the outer surface of the support base 3. A drive gear 61 is fixedly connected to the output shaft of the support base 3. A driven gear 61 meshes with the upper outer surface of the drive gear 61. The inner surface of the driven gear 62 is fixedly connected to the outer surface of the fixed sleeve 4. The round tube clamping mechanism 5 is mounted on the upper end of the cutting equipment body 1, clamping both ends of the nickel-titanium alloy tube according to its dimensions. At this time, the two ends of the round tube are threaded through the round tube support mechanism. When the telescopic rod 11 extends and retracts synchronously, the sliding sleeve 12 slides on the surface of the limiting slide post 10, thereby achieving outward support of the support sleeve plate 14, pressing the inner wall of the round tube tightly to prevent deformation of the cut. The horizontal position is adjusted according to the cutting position of the round tube by extending and retracting the electric telescopic rod 7. When clamping and fixing is required... When the nickel-titanium alloy tube rotates, the drive motor 6 is turned on, causing its output shaft to rotate as the central hub for power transmission. At this time, the active rotating gear 61 rotates, and under the action of meshing gear force, the driven rotating gear 62 rotates synchronously. At the same time, the round tube clamping mechanism 5 connected to the driven rotating gear 62 and the round tube clamping mechanism 5 rotate as a whole, realizing the rotation of the clamped round tube. This facilitates the cutting of the round tube at the cutting position and further solves the problem that the cutting position of the nickel-titanium alloy tube is prone to deformation after being cut into two sections. It can support the inner diameter of the cut round tube to prevent deformation of the cutting position.

[0032] Example 2

[0033] Based on Embodiment 1, this embodiment adds a convenient assembly mechanism:

[0034] The convenient assembly mechanism includes a retaining plate 19, with a triangular plate 20 fixedly attached to one end of the retaining plate 19. The triangular plate 20 is an equilateral triangular plate structure. Both the retaining plate 19 and the triangular plate 20 are provided in two sets. The retaining plates 19 and the triangular plate 20 are symmetrically distributed about the piston rod of the electric telescopic rod 7. The end of the retaining plate 19 away from the triangular plate 20 passes through the inner wall of the mounting circular plate 8 and slides through the inner wall of the pre-set retaining groove 81 on the inner surface. Two sets of retaining grooves 81 are provided, and they are symmetrically distributed about the central axis of the mounting circular plate 8. The inner surface of the connecting frame plate 9 is provided with auxiliary limiting grooves 91. Two sets of limiting grooves 91 are provided, and they are symmetrically distributed about the central axis of the connecting frame plate 9. The inner wall of the limiting groove 91 slides into the outer surface of the retaining plate 19. The inner wall of the end of the card strip 19 away from the triangular plate 20 is provided with a receiving groove 21. The inner wall of the outer side of the receiving groove 21 is provided with a limiting groove 22 for auxiliary limiting. The receiving groove 21 and the limiting groove 22 are both set in two sets, and the receiving groove 21 and the limiting groove 22 are symmetrically distributed about the central axis of the card strip 19. An elastic component is provided on the inner wall of the receiving groove 21. The elastic component includes a spring 23. One end of the spring 23 is fixedly connected to the inner wall of the receiving groove 21. The other end of the spring 23 is fixedly connected to a moving block 24. The outer surface of the moving block 24 is slidably connected to the inner wall of the spring 23. A paddle 241 is fixedly added to the outer surface of the moving block 24. The outer surface of the paddle 241 is slidably connected to the inner wall of the limiting groove 22. A locking assembly is installed on the outer surface of the moving block 24 away from the spring 23.

[0035] With the convenient assembly mechanism, the piston rod at the output end of the electric telescopic rod 7 is connected to the mounting circular plate 8, and an auxiliary limiting groove 81 is preset on the surface of the mounting circular plate 8. At this time, the triangular plate 20 added to one end of the locking strip 19 is locked with the limiting groove 91. Then, the end of the locking strip 19 away from the triangular plate 20 passes through the groove 81. The user manually moves the lever 241 inward. At this time, the lever 241 slides on the inner wall of the limiting slide groove 22. The spring 23 is compressed by the pushing force generated by the movement of the moving block 24. At this time, the metal spring 25 connecting the moving block 24 and the fitting plate 251 move into the inner groove of the receiving groove 21. The fitting plate 251 is hidden in the receiving groove. Inside the receiving groove 21, the opening of the slot 81 is avoided. When one end of the locking strip 19 is fully inserted into the slot 81, the user releases the lever 241 with their finger, causing the spring 23 to return to its original position. This allows the metal spring 25 and the mating plate 251 to extend out, blocking the opening of the slot 81 and preventing the locking strip 19, the triangular plate 20, and the connecting frame plate 9 from separating. This enables the quick assembly of the connecting frame plate 9 and the round tube support mechanism on the side, replacing the traditional welding fixing method. This facilitates disassembly and assembly and further solves the problem that the cut end of the existing nickel-titanium alloy tube is prone to deformation after being cut into two sections. It can support the inner diameter of the cut round tube to prevent deformation of the cut end.

[0036] Example 3

[0037] Based on Embodiment 2, this embodiment adds a circular tube top support mechanism:

[0038] The circular tube top support mechanism includes a limiting sliding column 10 and a telescopic rod 11. One end of the limiting sliding column 10 and the telescopic rod 11 are evenly connected to the outer side of the connecting frame plate 9 and fixedly connected. The telescopic rod 11 is configured in four sets. A sliding sleeve 12 is fixedly added to the end of the telescopic rod 11 away from the connecting frame plate 9. The sliding sleeve 12 has a "T"-shaped annular structure. The inner wall of the sliding sleeve 12 is slidably connected to the outer surface of the limiting sliding column 10. A hinge rod 13 is hinged to the outer surface of the sliding sleeve 12. The other end of the hinge rod 13 is hinged to a support tube sleeve plate 14. An anti-slip component is fixedly added to the outside of the support tube sleeve plate 14. One end of the limiting slide column 10 away from the connecting frame plate 9 is fixedly sleeved with an I-shaped sleeve 15. The I-shaped sleeve 15 has an overall "I"-shaped ring structure. The outer surfaces of the two ends of the I-shaped sleeve 15 are respectively hinged with hinge rod 2 16 and hinge rod 3 17. There are four sets of hinge rod 2 16 and hinge rod 3 17 respectively, and hinge rod 2 16 and hinge rod 3 17 always remain parallel. The other end of hinge rod 2 16 and hinge rod 3 17 is rotatably connected to the inner surface of the support tube sleeve plate 14. The inner cavity of the support tube sleeve plate 14 is provided with a squeezing cavity 18, and the inside of the squeezing cavity 18 is provided with an elastic pushing component.

[0039] At this time, the round tube is outside the supporting assembly, and the limiting slide column 10 is on the central axis of the round tube. Control the extension and retraction of the electric telescopic rod 7 to move the round tube supporting mechanism to both sides of the cutting opening. When it is necessary to tighten the inner wall of the round tube, control the extension and retraction of the telescopic rod 11 simultaneously. The sliding sleeve 12 slides on the surface of the limiting slide column 10. At this time, the angles of the first hinge rod 13 and the second hinge rod 16 are changed. When the sliding sleeve 12 moves towards the I-shaped sleeve 15, multiple sets of supporting sleeve plates 14 are pushed outward simultaneously. Conversely, when the sliding sleeve 12 retracts towards the connecting frame plate 9, the supporting sleeve plates 14 retract inward. This can support the inner diameter of the cut position of the nickel-titanium alloy tube, avoid deformation of the cut position during cutting, and further solve the problem that the cut position is prone to deformation after the existing nickel-titanium alloy tube is cut into two sections. It can support the inner diameter of the cut round tube and prevent deformation of the cut.

[0040] Example 4

[0041] Based on Embodiment 3, this embodiment adds a locking component:

[0042] The locking assembly includes a metal spring 25 and a T-shaped seat 26. One end of the metal spring 25 is fixedly connected to the end of the moving block 24 away from the spring 23. The other end of the metal spring 25 is fixedly provided with a mating plate 251. The mating plate 251 is in the shape of a triangular block. The T-shaped seat 26 is fixedly installed on the outside of the mounting circular plate 8. The lower end of the T-shaped seat 26 is fixedly connected with a hook plate 27, and the lower inner wall of the hook plate 27 is provided with a groove that fits with the mating plate 251.

[0043] By adding a locking component, the locking of the locking strip 19 and the connecting frame plate 9 after they overlap is achieved, preventing slippage. At this time, the metal spring 25 is pressed down slightly. At this time, the mating plate 251 at one end of the metal spring 25 passes through the groove inside the hook plate 27 while the spring 23 is pushed back. When the hand is removed, the metal spring 25 is reset, thereby achieving the locking between the mating plate 251 and the hook plate 27 and preventing slippage. This further solves the problem that the cut end of the existing nickel-titanium alloy tube is prone to deformation after being cut into two sections. It can support the inner diameter of the cut tube to prevent deformation of the cut end.

[0044] Example 5

[0045] Based on Example 4, this example adds an anti-slip component:

[0046] The anti-slip component includes rubber anti-slip contact pieces 141, which are evenly distributed on the outer curved surface of the support sleeve plate 14, and all rubber anti-slip contact pieces 141 are circular sheet-like structures.

[0047] By adding evenly distributed rubber anti-slip contact pieces 141 to the surface of the support sleeve 14, the inner wall of the nickel-titanium alloy tube can be stably supported. When the round tube is rotated, the friction between the support sleeve 14 and the inner wall of the round tube is increased, which further solves the problem that the cut end is prone to deformation after the existing nickel-titanium alloy tube is cut into two sections. It can support the inner diameter of the cut round tube and prevent the cut end from deforming.

[0048] Example 6

[0049] Based on Embodiment 5, this embodiment adds an elastic pushing component:

[0050] The elastic pushing assembly includes a trapezoidal central pressure plate 181, which is located at the center of the extrusion chamber 18 and is fixedly connected to the inner wall of the extrusion chamber 18. The trapezoidal central pressure plate 181 has an overall trapezoidal structure. Arc-shaped elastic winglets 182 are fixedly connected to both sides of the trapezoidal central pressure plate 181. The arc-shaped elastic winglets 182 are mirror-distributed about the vertical center line of the trapezoidal central pressure plate 181. A support diagonal strip 183 is fixedly connected to the inner side of the arc-shaped elastic winglet 182. The support diagonal strip 183 has a square strip structure.

[0051] An elastic pushing component is added to the inner cavity of the support sleeve 14. When the outside of the support sleeve 14 contacts the inner wall of the round tube, the trapezoidal central pressure plate 181 and the arc-shaped elastic wing 182 are compressed and deformed, which will generate a certain reverse elastic force, thereby enhancing the clamping force of the support sleeve 14 on the nickel-titanium alloy tube. The reason for adding the obliquely arranged support strips 183 between the arc-shaped elastic wing 182 is to strengthen the support force of the support sleeve 14 and further solve the problem that the cut position is prone to deformation after the existing nickel-titanium alloy tube is cut into two sections. It can support the inner diameter of the cut round tube and prevent the cut from deforming.

[0052] In actual use, firstly, the round tube clamping mechanism 5 is mounted on the upper end of the cutting equipment body 1, and the two ends of the nickel-titanium alloy tube are clamped according to its size. At this time, the two ends of the round tube are inserted with the round tube top support mechanism. When it is necessary to rotate the clamped nickel-titanium alloy tube, the drive motor 6 is turned on, so that its output shaft rotates as the central hub of power transmission. At this time, the active rotating gear 61 rotates, and under the action of the meshing gear force, the driven rotating gear 62 rotates synchronously. At this time, the round tube clamping mechanism 5 connected to the driven rotating gear 62 and the round tube clamping mechanism 5 rotate as a whole, realizing the rotation of the clamped round tube. The electric telescopic rod 7 extends and retracts, moving the round tube support mechanism to both sides of the cutting opening. When it is necessary to tighten the inner wall of the round tube, the telescopic rod 11 extends and retracts synchronously, and the sliding sleeve 12 slides on the surface of the limiting slide column 10. At this time, the angles of the first hinge rod 13 and the second hinge rod 16 are changed. When the sliding sleeve 12 moves towards the I-shaped sleeve 15, multiple sets of support sleeve plates 14 are pushed outwards synchronously. Conversely, when the sliding sleeve 12 retracts towards the connecting frame plate 9, the support sleeve plates 14 retract inwards. This can support the inner diameter of the cut position of the nickel-titanium alloy tube and avoid deformation of the cut position during cutting.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
