Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0030] Example 1

[0031] This embodiment provides Figures 1 to 6 The clamping device shown is used for finishing titanium alloy pipe fittings, including a base 1, a first support column 101 is vertically arranged on the left side of the base 1, a second support column 102 is vertically arranged on the right side of the base 1, a first mounting seat 103 is arranged on the first support column 101, and a second mounting seat 104 is arranged on the second support column 102.

[0032] The machine also includes a horizontally arranged rotating shaft 2, with rotating bearings 3 sleeved on both ends of the rotating shaft 2. The rotating bearings 3 are arranged on the left side of the rotating shaft 2, and a motor 4 is arranged. A clamping mechanism 7 is provided on the rotating shaft 2. The provision of the rotating bearings 3 improves the rotation accuracy of the rotating shaft 2 during operation, which can effectively improve the processing accuracy of the titanium alloy pipe fittings.

[0033] The rotating shaft 2 is provided with a thread 5, which is located between the two rotating bearings 3. The rotating shaft 2 is provided with a rotating wheel 6, which is threadedly connected to the rotating wheel 6. The rotating wheel 6 rotates on the thread 5 to perform axial feed motion. At the same time, due to the characteristics of the thread 5, the rotating shaft 2 will also drive the rotating wheel 6 to rotate during the rotation process, thereby preventing the relative displacement of the rotating wheel 6 from causing axial movement, forming a self-locking structure.

[0034] The clamping mechanism 7 includes a first mounting block 701 arranged on the rotating wheel 6, the first mounting block 701 is rotatably connected to the rotating wheel 6, and a second mounting block 702 is fixedly arranged on the right end of the rotating shaft 2, and a plurality of mounting terminals 703 are arranged on the first mounting block 701 and the second mounting block 702, and a mounting rod 704 is fixedly arranged on the upper end of the mounting terminal 703, and the mounting rod 704 passes through the mounting terminal 703, and a supporting mechanism 705 is arranged on the mounting rod 704, and the lower end of the supporting mechanism 705 is hingedly connected to the mounting rod 704, and a T-shaped support plate 706 is arranged on the upper end of the supporting mechanism 705, and the support plate 706 is hingedly connected to the support mechanism 705.

[0035] Among them, the movement of the rotating wheel 6 drives the first mounting block 701 to move left and right. Since the second mounting block 702 is fixed, when the first mounting block 701 moves to the right, it drives the support mechanism 705 to move, and further drives the support plate 706 to expand outward. Through this structural setting, the axial linear movement of the rotating wheel 6 is converted into the radial linear movement of the support plate 706, thereby realizing the clamping action of the entire clamping mechanism 7.

[0036] Furthermore, the support mechanism 705 includes a plurality of support rods in groups of two, and a group of support rods includes a first support rod 7051 and a second support rod 7052. The left end of the first support rod 7051 is set on the mounting terminal 703 of the first mounting block 701, and the right end is hingedly connected to the right end of the support plate 706. The left end of the second support rod 7052 is hingedly connected to the left end of the support plate 706, and the right end is set on the mounting terminal 703 of the second mounting block 702. The first support rod 7051 and the second support rod 7052 are hingedly connected at the center.

[0037] The structural arrangement of the first support rod 7051 and the second support 7052 enables the support mechanism 705 to form a scissor-type structure, so that the entire clamping device has a stable clamping force while also providing a larger adjustment range to accommodate titanium alloy pipes of different sizes and inner diameters.

[0038] Further, such as Figure 1 and Figure 2 As shown, the mounting terminals 703, mounting rods 704, support mechanisms 705, and support plates 706 are all arranged around the circumference of the rotating shaft 2. Specifically, four groups of mounting terminals 703, mounting rods 704, support mechanisms 705, and support plates 706 are arranged around the rotating shaft 2, which makes the clamping more stable while significantly reducing the support force on the inner diameter of the pipe, thereby avoiding deformation of the pipe during processing.

[0039] Further, such as Figure 4As shown, the thread 5 is located on the right side of the left rotating bearing 3. The starting end of the thread 5 is set to the right side of the rotating bearing 3, and the thread length is set to 10cm-15cm. This is used to control the axial feed of the rotating wheel 6, which actually limits the radial feed of the entire clamping mechanism 7. At the same time, the thread length also serves as a limit to prevent excessive movement of the rotating wheel 6.

[0040] Further, such as Figure 3 As shown, the rotating wheel 6 is configured in an H-shape, with the first mounting block 701 disposed within a groove of the rotating wheel 6. The first mounting block 701 and the second mounting block 702 are arranged at the same height. This H-shaped arrangement prevents the first mounting block 701 from separating from the rotating wheel 6, and does not cause the first mounting block 701 to rotate with the rotating wheel 6. Furthermore, by arranging the first mounting block 701 and the second mounting block 702 at the same height, the support plate 706 is effectively maintained parallel to the rotating shaft 2.

[0041] Furthermore, the first mounting seat 103 is fixedly connected to the first support column 101 , and the second support column 102 is hollow inside and is provided with a lifting mechanism 8 .

[0042] Further, such as Figure 5 As shown, the lifting mechanism 8 includes a horizontally arranged rotating rod 802, one end of which is fixedly provided with a wheel disc 801, and the other end of which is fixedly provided with a first bevel gear 803; it also includes a screw 805 vertically arranged in the second support column 102, the lower end of which is fixedly provided with a second bevel gear 804, the first bevel gear 803 and the second bevel gear 804 are meshed with each other, and the rotating rod 802 and the screw 805 are arranged through the L-shaped fixed plate; the upper end of the screw (805) is fixed A limiting plate 808 is provided, the left end of the limiting plate 808 is fixedly connected to the inner wall of the second support column 102, an L-shaped lifting block 806 is provided on the lead screw 805, the bottom end of the lifting block 806 is threadedly connected to the lead screw 805, the top end of the lifting block 806 is fixedly connected to the second mounting seat 104, the lifting block 806 is provided in the concave-shaped fixing groove 807 and is slidably connected to the fixing groove 807, and the front and rear ends of the fixing groove 807 are fixedly provided to the inner wall of the second support column 102.

[0043] In order to facilitate the disassembly of the pipe fittings and protect the rotating bearing 3 from being damaged, the second support column 102 is hollowed and a lifting mechanism 8 is provided. When replacing the pipe fittings, it is only necessary to rotate the wheel disc 801 counterclockwise to drive the rotating rod 802 to rotate, thereby driving the first bevel gear 803 to rotate, and the second bevel gear 804 rotates accordingly and drives the screw 805 to rotate. Since the screw 805 is fixed, the lifting block 806 will move downward under the restriction of the fixed groove 807, and finally drive the second mounting seat 104 to descend. After the pipe fitting is replaced, the wheel disc 801 is rotated clockwise until the second mounting seat 104 is raised to the top. A limit plate 808 is provided to limit the lifting block 806 from excessive movement and ensure that the second mounting seat 104 maintains the same horizontal height as the first mounting seat 103 when it is raised to the top.

[0044] When in use, first rotate the wheel 801 counterclockwise to activate the lifting mechanism 8, thereby driving the second mounting seat 104 to move downward. After the second mounting seat 104 is lowered to the bottom, the required pipe to be processed is placed horizontally on the clamping mechanism 7, and then the wheel 801 is rotated clockwise again until the second mounting seat 104 is raised to the top.

[0045] The rotating wheel 6 is rotated, and the rotating wheel 6 moves axially on the thread 5, thereby driving the support mechanism 705 to move. The distance between the lower ends of the first support rod 7051 and the second support rod 7052 is reduced, so that the entire support mechanism 705 is expanded, and finally the clamping action of the clamping mechanism 7 is completed. During this process, the pipe is always centered on the rotating shaft 2;

[0046] During operation, the motor 4 is started, and the motor 4 drives the shaft 2 and thus the entire clamping mechanism 7 to rotate at a constant speed. It should be noted that the rotation direction of the shaft 2 is in the same direction as the feed direction of the thread 5, so as to further limit the rotating block 6 so that it does not move relative to the thread 5 during operation.

[0047] After the process is completed, the second mounting seat 104 is lowered, the processed pipe is removed, and the position of the second mounting seat 104 is restored.

[0048] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
