Description

Technical Field

[0001] This utility model belongs to the field of metal tube processing technology, specifically relating to an adjustable metal tube processing device. Background Technology

[0002] With the continuous development of industrial manufacturing technology, metal pipes are being used more and more widely in various engineering fields, such as construction, energy and transportation.

[0003] According to the published patent CN220313133U: A pipe clamp includes a clamp body, which comprises a base plate and a second side plate and a first side plate disposed opposite to each other. The first side plate has multiple clamping portions, each including a buffer chamber located inside the first side plate. One end of the buffer chamber is connected to a limiting channel, and the diameter of the buffer chamber is larger than the diameter of the limiting channel. The clamping portion also includes an arc-shaped clamping plate, one end of which has a connecting rod. One end of the connecting rod passes through the buffer chamber and is located inside the limiting channel. The portion of the connecting rod inside the buffer chamber has a baffle and a spring. One end of the spring is connected to the baffle, and the other end is connected to the end of the buffer chamber away from the arc-shaped clamping plate. A driving rod is located within the limiting channel, capable of driving the connecting rod to move. The arc-shaped clamping plates in at least two clamping portions have different curvatures. This device can clamp pipes of various diameters.

[0004] However, there are still shortcomings. For example, the patent uses clamping components on two side plates to fix the pipe.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-4 This utility model provides an adjustable metal tube processing device. Its specific implementation will be described in detail with reference to the accompanying drawings and embodiments. The core structure of the device includes a worktable 1, a servo motor 5, a lead screw 6, a guide rod 7, a movable plate 10, a fixed plate 11, a connecting ring 12, a rotating part 13, a fixed clamp 16, a movable clamp 17, a first rubber buffer sleeve 22, a second rubber buffer sleeve 23, and key components such as an adjusting screw 20 and an adjusting screw hole 21. These components, through precise design and reasonable layout, achieve high-precision positioning, flexible angle adjustment, and surface protection functions for the metal tube.

[0025] like Figure 1 and Figure 2 As shown, the worktable 1, as the basic component of the entire fixture, has four support legs 2 welded to its four corners. The height of each support leg 2 is precisely calculated to ensure sufficient stability and balance of the fixture during use. The bottom of the support legs 2 is equipped with anti-slip pads made of high-friction rubber material, which further enhances the anti-slip performance of the fixture during processing. The worktable 1 has two rectangular slots inside, namely the first rectangular slot 3 and the second rectangular slot 4. The first rectangular slot 3 is used to install the lead screw 6, while the second rectangular slot 4 is used to fix the guide rod 7. The lead screw 6 is installed in the first rectangular slot 3 through bearings and is connected to the servo motor 5 through a coupling. The servo motor 5 is detachably fixed to one side of the worktable 1 with cross screws for easy maintenance and replacement. The guide rod 7 is fixed in the second rectangular slot 4, and its outer wall is slidably connected to the guide block 8. The sliding direction of the guide block 8 is parallel to the axis of the lead screw 6, thereby limiting the movement trajectory of the moving block 9 and ensuring that the movable plate 10 moves in a straight line.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the movable plate 10 and the fixed plate 11 are key components in the tooling for initial clamping of the metal tube. A connecting ring 12 is fixedly connected to one side of both the movable plate 10 and the fixed plate 11. A rotating part 13 is rotatably connected inside the connecting ring 12. There are two rotating parts 13; one rotating part 13 has a first connecting shaft 14 fixedly connected to its inner wall, and the other rotating part 13 has a second connecting shaft 15 fixedly connected to its inner wall. The first connecting shaft 14 and the second connecting shaft 15 are respectively connected to the fixed clamp 16 and the movable clamp 17. Both the fixed clamp 16 and the movable clamp 17 are arc-shaped, have the same dimensions, and are suitable for different diameters. The inner wall of the fixed clamp 16 is fixedly connected to a second rubber buffer sleeve 23, and the inner wall of the movable clamp 17 is fixedly connected to a first rubber buffer sleeve 22. The thickness of the first rubber buffer sleeve 22 and the second rubber buffer sleeve 23 are precisely calculated, and the material is selected with an appropriate elastic modulus. This allows for a uniform pressure distribution during clamping, effectively absorbing the impact force generated during clamping and preventing damage to the surface of the metal tube due to excessive clamping force. Both the first rubber buffer sleeve 22 and the second rubber buffer sleeve 23 have arc-shaped openings inside. The design of these arc-shaped openings further enhances the buffering effect during clamping.

[0027] like Figure 3 and Figure 4As shown, the outer wall of the rotating part 13 is provided with four adjusting screw holes 21, which are evenly distributed on the outer wall of the rotating part 13. The adjusting screw 20 passes through the connecting ring 12 and is connected to the adjusting screw hole 21 by thread. The clamp angle can be precisely adjusted by the cooperation of the adjusting screw 20 and the adjusting screw hole 21. The distribution position of the adjusting screw hole 21 is precisely calculated to ensure the uniformity of force on the clamp at different angles and to avoid clamp skew. In addition, a ball bearing 18 is fixedly connected to the outer wall of the rotating part 13. The inner wall of the connecting ring 12 is provided with a rotating groove 19 that matches the ball bearing 18. The ball bearing 18 can rotate freely in the rotating groove 19, thereby realizing the flexible rotation of the clamp. The contact surface between the ball bearing 18 and the rotating groove 19 is precision machined to ensure that the ball bearing 18 has low frictional resistance during rotation and maintains stable rotation performance. The number of balls bearing 18 is reasonably arranged according to the size of the rotating part 13 to ensure that the rotating part 13 is evenly stressed during rotation and to avoid jamming.

[0028] The clamping assembly of this utility model achieves efficient clamping of metal tubes in the following way: the metal tube to be processed is placed between the fixed clamp 16 and the movable clamp 17, the servo motor 5 is started, and the servo motor 5 drives the lead screw 6 to rotate through the coupling. The lead screw 6 drives the moving block 9 to move along the first rectangular groove 3, thereby pushing the movable plate 10 closer to or away from the fixed plate 11, thus achieving initial clamping of the metal tube. According to the processing requirements, the angle of the fixed clamp 16 and the movable clamp 17 is adjusted by adjusting the screw 20 and adjusting the screw hole 21 to put the metal tube in the optimal processing position. During the clamping process, the first rubber buffer sleeve 22 and the second rubber buffer sleeve 23 absorb the impact force generated during the clamping process through their internal arc-shaped openings to avoid damage to the metal tube.

[0029] The working principle and usage process of this utility model are as follows: First, the metal tube to be processed is placed between the fixed clamp 16 and the movable clamp 17. Then, the servo motor 5 is started. The servo motor 5 drives the lead screw 6 to rotate through the coupling. The lead screw 6 drives the moving block 9 to move along the first rectangular groove 3, thereby pushing the movable plate 10 closer to or away from the fixed plate 11 to achieve the initial clamping of the metal tube. According to the processing requirements, the angle of the fixed clamp 16 and the movable clamp 17 is adjusted by adjusting the screw 20 and adjusting the screw hole 21 to make the metal tube in the optimal processing position. During the clamping process, the first rubber buffer sleeve 22 and the second rubber buffer sleeve 23 absorb the impact force generated during the clamping process through their internal arc-shaped openings to avoid damage to the metal tube.

[0030] Although embodiments of the present 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
