Conventionally, when performing surface polishing treatment operations on some stainless steel special material steel pipes with non-extra-large specifications, they are usually manually transferred to the clamping structure in the processing equipment. Among them, in order to ensure the accuracy and consistency of the butt joint between the steel pipe and the clamping structures at both ends, more time needs to be spent on position alignment and trial and error, thus affecting the production rhythm of the surface treatment of a large number of steel pipes.

[0018] Embodiment 1

[0019] In order to effectively solve the problem of the long time-consuming when the steel pipe is docked with the clamping structures at both ends in the surface treatment device before surface treatment, please refer to Figures 1-7 , the present invention proposes a surface treatment device for stainless steel special materials processing, including a steel pipe special material 2 arranged above a slide rail seat 1, a surface treatment component 3 is arranged above the steel pipe special material 2, and an electric slide rail structure 4 for driving the surface treatment component 3 to move horizontally along the surface of the steel pipe special material 2 is installed between both sides of the slide rail seat 1. The principle of the electric slide rail structure 4 is basically the same as that of the prior art, aiming to drive the surface treatment component 3 to move horizontally and expand the range of surface treatment of the steel pipe special material 2. An end clamping mechanism 5 for driving the steel pipe special material 2 to rotate at a constant speed is installed on the slide rail seat 1, and a loading mechanism 6 for lifting steel pipe special materials 2 with different length specifications to the docking height of the end clamping mechanism 5 while keeping them in a balanced state is installed on the slide rail seat 1. By placing the steel pipe special material 2 on the loading mechanism 6 and operating the loading mechanism 6 to lift the steel pipe special material 2 upward to a position where the centers of both ends are at the same height as the set position in the end clamping mechanism 5, and then cooperating with the operation of the end clamping mechanism 5 itself to clamp both ends of the steel pipe special material 2 and drive it to rotate at a constant speed. After that, the surface treatment component 3 is driven by the electric slide rail structure 4 to perform polishing operations along the surface of the rotating steel pipe special material 2. By using the loading mechanism 6 to lift it upward to the set position according to the diameter size of the steel pipe special material 2 and dock it with both ends of the end clamping mechanism 5, the docking accuracy and efficiency can be effectively improved.

[0020] Among them, as Figure 1 and Figure 2As shown in the figure, the slide rail base 1 of this embodiment includes a workbench frame and two rack slide rails installed on the top surface of the workbench frame. The two rack slide rails are arranged in a front-back mirror image. The end clamping mechanism 5 includes a carrier 501 fitted on the opposite sides of the two rack slide rails. A servo motor 502 is installed on the carrier 501. The output end of the servo motor 502 is installed with a spur gear 503 that meshes with one of the rack slide rails through tooth grooves. Four-jaw chucks 504 are rotatably installed on one side of the workbench frame and on the carrier 501. A drive motor 505 for driving connection with the four-jaw chuck 504 is also installed on the carrier 501. Continuing from the above, after the loading mechanism 6 lifts the steel pipe special material 2 to a set height position, the servo motor 502 is operated to drive the spur gear 503 to rotate relative to the rack slide rail, thereby driving the carrier 501 and its related structures to move horizontally along the slide rail base 1, so as to finally adjust the distance between the two four-jaw chucks 504 according to the length of the steel pipe special material 2 to be processed. And during this process, the two ends of the steel pipe special material 2 are clamped by the four-jaw chuck 504. At this time, the loading mechanism 6 returns to its original state to avoid hindering the subsequent horizontal movement of the surface treatment assembly 3. Among them, when the drive motor 505 is operated to drive one of the four-jaw chucks 504 to rotate, the clamped steel pipe special material 2 and the other four-jaw chuck 504 rotate accordingly, so that the steel pipe special material 2 rotates relative to the surface treatment assembly 3, thereby ensuring that all positions on the circumference of the surface of the steel pipe special material 2 can be processed.

[0021] Embodiment 2

[0022] In actual processing, there are various types of length specifications for the steel pipe special material 2. When the long-specification steel pipe special material 2 is placed on the loading mechanism 6 and the loading mechanism 6 drives it to rise, this steel pipe special material 2 may change from a horizontal placement state to an inclined state due to unstable center of gravity or insufficient friction with the loading mechanism 6, thus affecting the subsequent docking accuracy and efficiency between the two four-jaw chucks 504 in the end clamping mechanism 5. To effectively solve the above problems, as Figure 1 , Figures 3-5As shown in the figure, the bearing mechanism 6 includes a hydraulic cylinder 601 installed on the slide rail base 1. Above the slide rail base 1, there are two U-shaped support rings 602 located below the special steel pipe 2. The U-shaped support rings 602 are equipped with sensors for sensing the special steel pipe 2, and preferably gravity sensors, optical sensors, etc. At the free end of the hydraulic cylinder 601, there is a connecting rod 603 connected to the bottoms of the two U-shaped support rings 602. At both ends of the top of the U-shaped support ring 602, there are rotatably connected limit pressing plates 604. On one of the U-shaped support rings 602, there is an adjustment component 605 for controlling the adjustment between the vertical state and the inclined state of the two limit pressing plates 604. After the special steel pipe 2 is placed in the two U-shaped support rings 602, when the sensors in the U-shaped support rings 602 sense the special steel pipe 2, they will feedback signals to the adjustment component 605, prompting the adjustment component 605 to drive the two limit pressing plates 604 on the U-shaped support ring 602 to incline towards the relative direction. Finally, the relative sides of the two limit pressing plates 604 are attached to the upper surface of the special steel pipe 2, and together with the U-shaped support ring 602 itself, they generate a clamping effect on the special steel pipe 2, thereby effectively avoiding the stability and balance of the placement of the special steel pipe 2 with a length specification greater than twice the distance between the two U-shaped support rings 602, and ensuring that it will not tilt.

[0023] Among them, the surface of the limit pressing plate 604 is provided with an embedded chute. On the relative sides of the limit pressing plates 604 arranged in a pairwise front-back mirror image, anti-slip gaskets are bonded. The anti-slip gaskets are used to increase the friction when the limit pressing plate 604 contacts the surface of the special steel pipe 2, and at the same time avoid scratching the surface of the special steel pipe 2 by the limit pressing plate 604.

[0024] Specifically, the adjustment component 605 includes a steel plate structure 6051 installed at the bottom of one of the U-shaped support rings 602. Inside the embedded chute, there is a cylindrical bar 6052. An L-shaped steel plate 6053 is sleeved on the outer surface of the cylindrical bar 6052. On the steel plate structure 6051, there is a driving structure 6054 for driving the two L-shaped steel plates 6053 arranged in a front-back mirror image to adjust the distance, so as to adjust the arrangement state of the front and back two limit pressing plates 604. The driving structure 6054 is basically the same as the prior art, mainly composed of a motor, a bidirectional lead screw and a guide rod, aiming to control the L-shaped steel plates 6053 sleeved at both ends of the bidirectional lead screw to move towards the relative or opposite direction by running the motor. When the L-shaped steel plate 6053 moves, it correspondingly generates a thrust or a pulling force on the limit pressing plate 604, aiming to control it to rotate a set angle forward and backward with the connection point with the U-shaped support ring 602 as the center.

[0025] More specifically, the adjustment component 605 further includes an integral rod 6055 installed between the two horizontally arranged L-shaped steel plates 6053, aiming to make the limit pressing plates 604 on the left and right U-shaped support rings 602 maintain the same frequency and speed adjustment.

[0026] Continuing from the above, it can be seen that in this embodiment, the setting of the adjusting component 605 can, after placing the special steel pipe 2 on the U-shaped supporting ring 602, control the limiting pressing plates 604 rotatably connected to both ends of the top of the two U-shaped supporting rings 602 to tilt and adjust towards the opposite direction, so as to apply a downward oblique pressing force on the upper surface of the special steel pipe 2 while supporting the special steel pipe 2 at two places, for maintaining the balance of the special steel pipe 2, thereby ensuring the accuracy during subsequent docking with the two four-jaw chucks 504.

[0027] Embodiment III

[0028] In the operation of surface polishing treatment of the special steel pipe 2, the time required for polishing a single special steel pipe 2 is relatively long. Therefore, in order to improve the overall processing efficiency to a certain extent, as Figure 1 and Figures 6-7 shown, the surface treatment component 3 includes a slider structure 301 sleeved on the electric slide rail structure 4. An electric telescopic rod 302 is installed at the bottom of the slider structure 301, and a polishing structure 303 is detachably installed at the free end of the electric telescopic rod 302. The polishing structure 303 includes an arc-shaped frame 3031 installed at the free end of the electric telescopic rod 302. Three polishing rollers 3032 arranged in an isosceles triangle are rotatably installed on the arc-shaped frame 3031, and the circular diameter of the circle drawn by the three points on the outer surface of the three polishing rollers 3032 is adapted to the minimum diameter size of the special steel pipe 2 to be processed. When processing the special steel pipe 2 with the minimum size, the outer surfaces of the three polishing rollers 3032 are all in contact with it. On the contrary, as the diameter size of the special steel pipe 2 to be processed increases, the surfaces of the two equal-height polishing rollers 3032 always remain in a state of being in contact with the surface of the special steel pipe 2, so as to better ensure the polishing uniformity and efficiency of the entire surface of the special steel pipe 2.

[0029] Continuing from the above, only the special steel pipe 2 rotates relative to the polishing rollers 3032, which usually causes the wear of the polishing rollers 3032 to be concentrated in a specific area in contact with the surface of the special steel pipe 2, resulting in uneven wear of the polishing rollers 3032 and shortening their service life. To solve this problem, as Figure 6 and Figure 7As shown in the figure, a transmission belt 3033 sleeving one end of three polishing rollers 3032 is arranged on one side of the arc-shaped frame 3031, and a stepping motor 3034 drivingly connected to one of the polishing rollers 3032 is installed on the other side of the arc-shaped frame 3031. The stepping motor 3034 is used to drive one of the polishing rollers 3032 to rotate. Subsequently, the other two polishing rollers 3032 are driven to rotate synchronously and in the same direction via the transmission belt 3033. Moreover, the rotation direction of the stepping motor 3034 is opposite to the rotation direction of the end clamping mechanism 5 for controlling the rotation of the special steel pipe 2, which can effectively reduce the scratches and irregular marks generated during the polishing process. At the same time, the polishing rollers 3032 and the special steel pipe 2 rotate in opposite directions, which can evenly distribute the wear and reduce the situation of excessive wear of the polishing rollers 3032 in some local areas, thereby prolonging their service life. In addition, due to the complex relative motion generated by the reverse rotation, the contact angle and direction during the polishing process are more diverse, which helps to remove tiny irregular protrusions and defects, thereby improving the surface finish and brightness.

[0030] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
