Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing, and in particular is a pipe processing support device with elastic support and fixation. Background Art

[0002] The elastically fixed pipe processing support device is a key supporting device in the pipe processing process. It provides stable and adaptable support for the pipe through elastic support elements and is widely used in multiple industries and scenarios.

[0003] According to the publication number CN108098384B, a flexible support and fixed pipe processing support device is provided, which includes a base plate, a fixed vertical plate, a sliding vertical plate, a placement plate, a support plug, a limiting sliding block, and a motor. The base plate is provided with a horizontal movable groove, a threaded adjustment rod, a crank handle, a fixed vertical plate, and a sliding vertical plate. The lower end of the base plate is provided with a support bottom rod, a placement sleeve, a rotating bearing, a bottom cover, a sliding square rod, a threaded support rod, a universal wheel, an internally threaded annular plate, and an anti-slip washer. The fixed vertical plate and the sliding vertical plate are provided with placement plates on the inner sides relative to each other. The placement plates on both sides are provided with support plugs on the inner sides relative to each other. The support plugs are provided with strip grooves, springs, limiting sliding blocks, and a motor. The present invention can adapt to various sizes of pipes according to their diameters. At the same time, the limiting sliding block at the end slides on the strip groove under the push of the edge of the pipe. The limiting sliding block can cooperate with the clamping and fixing of the end of the pipe, making processing more stable and flexible.

[0004] According to the aforementioned document, during use, the support plug utilizes a conical design, intended to conform to the inner wall of the pipe using this tapered structure to accommodate pipes of varying diameters. However, the inner wall shape and roughness of pipes of varying specifications and materials vary significantly, making the conical support plug difficult to perfectly adapt to all situations. When encountering pipes with irregular inner walls or large dimensional deviations, it cannot provide stable and uniform support, making the pipe susceptible to shaking or shifting during processing. Furthermore, the grooves and springs on the support plug are designed to allow the limiting sliding block to slide within the grooves, pushed by the edge of the pipe, thereby clamping the end of the pipe. However, the spring's fixed spring constant and stroke may result in inadequate clamping force for pipes of varying weights and materials. Excessive clamping force can damage thinner or softer pipes; too little clamping force fails to effectively secure the end of the pipe, causing it to shift during processing, impacting processing stability and safety.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a flexible support and fixed pipe processing support device, including a base plate 1 and a mounting plate 2, and further comprising:

[0031] The interference mechanism 3 is provided on one side of the mounting plate 2;

[0032] The interference mechanism 3 includes a square tube 301 fixedly connected to one side of the mounting plate 2, a mounting block 302 fixedly installed on one side of the interior of the square tube 301, four sliding blocks 303 are provided inside the square tube 301, and each two sliding blocks 303 form a group, the mounting blocks 302 are rotatably connected to four hinged rods 306 located inside the sliding blocks 303, a connecting block 307 located inside the hinged rods 306 is fixedly installed inside the sliding blocks 303, a conflict plate 304 located on the outer surface of the square tube 301 is fixedly installed on one end of the sliding blocks 303, and the two sliding blocks 303 are elastically connected by an elastic member 305;

[0033] The driving assembly 4 is disposed on the other side of the square tube 301 and can drive the hinge rod 306 to rotate.

[0034] The above scheme is adopted: the operator inserts the pipe into the surface of the square tube 301, and then the driving component 4 can be driven to make the hinged rod 306 rotate inside the mounting block 302. During the rotation, the connecting block 307 will slide inside the hinged rod 306, and the hinged rod 306 will push the connecting block 307, the sliding block 1 303 and the contact plate 304 to move. When the sliding block 1 303 moves, the elastic member 1 305 will be stretched, and then the contact plate 304 will move toward the inner wall of the pipe, and the contact plate 304 will contact the inner wall of the pipe. After the four contact plates 304 pass through the inner wall of the contact pipe, the pipe can be fixed. Finally, the driving component 4 is driven to make the hinged rod 306 push the contact plate 304 to contact the inner wall of the pipe, thereby avoiding shaking or deviation during the processing and improving the stability and safety of the processing.

[0035] like Figure 3 、 Figure 4 and Figure 5 As shown, the driving assembly 4 includes a motor 401 fixedly connected to the other side of the square tube 301, a screw 402 is fixedly installed on the output end of the motor 401, and an extrusion plate 403 is threadedly sleeved on the surface of the screw 402.

[0036] The above solution is adopted: through the design of the driving component 4, the motor 1 401 can be driven to rotate the screw rod 1 402. Since the screw rod 1 402 is threadedly connected to the extrusion plate 403, the extrusion plate 403 will slide on the surface of the screw rod 1 402, and the surface of the extrusion plate 403 will contact the four hinge rods 306 and squeeze the hinge rods 306 to rotate. The rotating hinge rods 306 will push the contact plate 304 to contact the inner wall of the pipe.

[0037] like Figure 5 and Figure 6 As shown, it also includes:

[0038] The driving mechanism 5 is provided on one side of the mounting plate 2 and includes four square shells 501 fixedly connected to the mounting plate 2. Four second sliding blocks 502 are slidably connected to the interior of the four square shells 501. The second sliding blocks 502 are elastically connected to the square shells 501 via second elastic members 503. An extrusion block 505 is slidably connected to the interior of the square shells 501. A connecting rod 504 is fixedly installed on one side of the extrusion block 505, and one end of the connecting rod 504 is fixedly connected to the extrusion plate 403.

[0039] The fixing mechanism 6 is disposed at the bottom end of the second sliding block 502 and is capable of contacting the surface of the pipe.

[0040] The above solution is adopted: through the design of the driving mechanism 5, when the extrusion plate 403 moves, it will drive the connecting rod 504 to move, and the connecting rod 504 will drive the extrusion block 505 to move to the side of the sliding block 2 502, and then the extrusion block 505 will resist and push the sliding block 2 502. When the sliding block 2 502 moves, the elastic part 2 503 will be stretched, and then the sliding block 2 502 will push the fixing mechanism 6 to move toward the outer surface of the pipe, and then the fixing mechanism 6 will contact the surface of the pipe, thereby assisting the fixing of the contact plate 304. Finally, the connecting rod 504 is linked by the extrusion plate 403 to make the fixing mechanism 6 resist the outer surface of the pipe, and cooperate with the contact plate 304, and cooperate from different angles or strengths. The two cooperate with each other to greatly increase the fixing effect, effectively ensuring that the pipe is stable and does not shake during processing.

[0041] like Figure 5 As shown, the fixing mechanism 6 includes a mounting shell 601 fixedly connected to the bottom end of the second elastic member 503 , and a resisting block 602 is slidably connected inside the mounting shell 601 . The resisting block 602 is elastically connected to the mounting shell 601 through the third elastic member 603 .

[0042] The above solution is adopted: through the design of the fixing mechanism 6, when the extrusion block 505 pushes the sliding block 2 502 to move, the sliding block 2 502 will push the mounting shell 601 down, and the mounting shell 601 will drive the resistance block 602 to move toward the surface of the pipe, and the surface of the resistance block 602 will resist the outer surface of the pipe. During the resistance process, the elastic member 3 603 will be compressed, and the resilience of the elastic member 3 603 will be utilized to improve the resistance effect of the resistance block 602, and then cooperate with the resistance plate 304 to increase its fixing effect.

[0043] like Figure 7 and Figure 8 As shown, it also includes:

[0044] The supporting mechanism 7 is arranged at the top of the base plate 1. The supporting mechanism 7 includes a protective shell 701 fixedly connected to the top of the base plate 1. A square plate 702 is arranged inside the protective shell 701. A presentation plate 703 is fixedly installed on the top of the square plate 702. A sliding hole 706 is provided on the surface of the square plate 702. A second motor 704 located inside the protective shell 701 is fixedly installed on the top of the base plate 1. A second screw rod 705 is fixedly installed on the output end of the second motor 704. The surface of the second screw rod 705 is threadedly connected to a driving block 707 located inside the sliding hole 706.

[0045] The above scheme is adopted: through the design of the supporting mechanism 7, while the interference mechanism 3 and the fixing mechanism 6 fix the pipe, the motor 2 704 can be driven to rotate the screw rod 2 705. Since the screw rod 2 705 is threadedly connected to the driving block 707, when the screw rod 2 705 rotates, the driving block 707 will move on the surface of the screw rod 2 705, and then the driving block 707 will move along the inner wall of the sliding hole 706, and push the square plate 702 and the presentation plate 703 to move, and the surface of the presentation plate 703 will contact the surface of the pipe, thereby supporting the pipe, and finally, by driving the motor 2 704, the driving block 707 pushes the presentation plate 703 to move, thereby supporting the pipe, thereby improving the accuracy and stability of the support, effectively reducing the shaking and deviation during pipe processing, and providing reliable guarantee for high-quality pipe processing.

[0046] like Figure 7 and Figure 8 As shown, it also includes:

[0047] The limiting assembly 8 is arranged on one side inside the protective shell 701. The limiting assembly 8 includes a slide rail 801 fixedly connected to one side inside the protective shell 701. The surface of the slide rail 801 is slidably connected to the limiting block 802, and one side of the limiting block 802 is fixedly connected to the surface of the driving block 707.

[0048] Adopting the above solution: through the design of the limiting component 8, when the driving block 707 moves, it will drive the limiting block 802 to slide on the surface of the slide rail 801, and during the sliding process, the driving block 707 can be limited, and during the limiting process, the driving block 707 can move normally.

[0049] like Figure 3 、 Figure 5 and Figure 8 As shown, a limiting rod 9 located inside the square plate 702 is fixedly installed on the top of the base plate 1, and the limiting rod 9 can slide inside the square plate 702. There are two limiting rods 9, and they are mirror-image designs. A square hole is opened on the surface of the square tube 301, and the connecting rod 504 can slide inside the square hole.

[0050] The above-mentioned solution is adopted: through the design of the limiting rod 9, when the square plate 702 moves, it will slide on the surface of the limiting rod 9, thereby being able to limit the presentation plate 703, and the limiting rod 9 is a mirror image design, thereby improving its limiting effect. Through the design of the square tube 301, since a square hole is provided on the surface of the square tube 301, when the connecting rod 504 slides, it can slide inside the square tube 301, and thus will not interfere with the movement of the connecting rod 504, and the surface of the connecting rod 504 fits with the inner wall of the square hole, thereby being able to limit the connecting rod 504, ensuring that the extrusion plate 403 can move stably.

[0051] like Figure 3 、 Figure 4 and Figure 5 As shown, the contact plate 304 and the contact block 602 are both arc-shaped, and are made of rubber material. There are two elastic members 305, and the two elastic members 305 are staggered.

[0052] The above solution is adopted: through the design of the contact plate 304 and the contact block 602, since the contact plate 304 and the contact block 602 are both arc-shaped, it is ensured that the contact plate 304 and the contact block 602 are fully fitted with the inner wall and outer surface of the pipe, ensuring the fixing effect, and the contact plate 304 and the contact block 602 are both made of rubber material, which can buffer and absorb energy through elastic deformation when the pipe is affected by external force or its own gravity, maintain the stable position and posture of the pipe, and ensure processing accuracy and quality. Through the design of the elastic member 305, since the two elastic members 305 are staggered, the two elastic members 305 will not interfere with each other when stretched, and the two elastic members 305 can pull the four sliding blocks 303 and the contact plate 304 to reset.

[0053] The working principle and use process of the present invention:

[0054] First, the operator needs to insert the pipe into the surface of the square cylinder 301, and then drive the motor 1 401 to rotate the screw rod 1 402, and the extrusion plate 403 will slide on the surface of the screw rod 1 402. The extrusion plate 403 will squeeze the hinge rod 306 to rotate so that the hinge rod 306 rotates inside the mounting block 302. During the rotation, the connecting block 307 will slide inside the hinge rod 306, and the hinge rod 306 will push the connecting block 307, the sliding block 1 303 and the contact plate 304 to move. When the sliding block 1 303 moves, the elastic member 1 305 will be stretched, and then the contact plate 304 will contact the inner wall of the pipe. After the four contact plates 304 contact the inner wall of the pipe, the pipe can be positioned and fixed.

[0055] When the extrusion plate 403 moves, it drives the connecting rod 504 to move, and the connecting rod 504 drives the extrusion block 505 to move toward the side of the second sliding block 502, and then the extrusion block 505 will resist and push the second sliding block 502. When the second sliding block 502 moves, the second elastic member 503 will be stretched, and the second sliding block 502 will install the shell 601 and the resistance block 602 to the surface of the pipe, and the surface of the resistance block 602 will resist the outer surface of the pipe. During the resistance process, the third elastic member 603 will be compressed, and the resilience of the third elastic member 603 will be utilized to improve the resistance effect of the resistance block 602, and then the resistance block 602 cooperates with the resistance plate 304 to increase its fixing effect.

[0056] While the resistance mechanism 3 and the fixing mechanism 6 are fixing the pipe, the motor 2 704 can be driven to rotate the screw 2 705, and the driving block 707 will move on the surface of the screw 2 705, and the driving block 707 will move along the inner wall of the sliding hole 706, and push the square plate 702 and the presentation plate 703 to move, and the surface of the presentation plate 703 will contact the surface of the pipe, thereby supporting the pipe, and then the operator can process the pipe and finally complete the operation process.

[0057] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
