Abstract
Description
Technical Field
[0001] This application relates to the field of pipe polishing, and more specifically, to a pipe polishing fixing mechanism. Background Technology
[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, resulting in a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece. During pipe production, the pipe surface needs to be polished to facilitate its use.
[0003] A fixing device for a pipe polishing machine, with publication number CN217122841U, fixes the pipe by inserting contact heads on the supports into both ends of the pipe. In this fixing device, there are two supports, and a linear module is used to adjust the gap between the two supports to place pipes of different lengths between the two supports. Therefore, the length of the linear module in this device determines the distance between the two supports, and its maximum stroke determines the pipe length that can be accommodated, which means that excessively long pipes (such as those exceeding the module's stroke) cannot be placed between the two supports.

[0033] Reference Figure 1-6 ,
[0034] A pipe polishing and fixing mechanism includes: a first fixing frame 1, a second fixing frame 2, a support plate 3, and a positioning element 4. Both the first fixing frame 1 and the second fixing frame 2 have perforated areas for the pipe ends to pass through. The support plate 3 is disposed within the perforated areas. The support plate 3 has a first support portion 31 and a second support portion 32 formed on it. Both the first support portion 31 and the second support portion 32 are plate-shaped structures. The first support portion 31 and the second support portion 32 are used to abut against the outer wall surface of the pipe. When the positioning element 4 is installed on the first fixing frame 1 and the second fixing frame 2, the positioning element 4 abuts against the outer wall surface of the pipe, thereby fixing the pipe to the support plate 3. The positioning element 4 is detachably connected to the first fixing frame 1 and the second fixing frame 2, facilitating the placement of polished or unpolished pipes within the perforated areas formed on the first fixing frame 1 and the second fixing frame 2. In cases where the pipe is long, the operator can allow both ends of the pipe to pass through the perforated areas formed on the first fixing frame 1 and the second fixing frame 2 respectively, and place the pipe on the support plate 3, avoiding the problem of the pipe being unable to be placed due to excessive length. The positioning element 4 forms a three-dimensional clamp by abutting against the top of the pipe and both sides of the support plate 3, preventing the pipe from rotating on the first support part 31 and the second support part 32 during the polishing process, so that the workers can carry out polishing operations on the pipe.
[0035] Specifically, the positioning component 4 includes a first positioning rod 41. The first positioning rod 41 is threadedly connected to the first fixing frame 1 or the second fixing frame 2. One end of the first positioning rod 41 abuts against the outer wall of the pipe, thereby fixing the pipe to the support plate 3, which is simple to operate. The threaded connection between the first positioning rod 41 and the first fixing frame 1 or the second fixing frame 2 is suitable for pipes of different diameters. Two first positioning rods 41 are provided.
[0036] Specifically, the end of the first positioning rod 41 is provided with an abutment block 411, a spring 412, and an abutment rod 413. A straight hole is formed on the abutment block 411 for the abutment rod 413 to pass through, and the abutment rod 413 passes through the abutment block 411 and is slidably connected to it. One end of the abutment rod 413 forms a positioning part 4131, and the other end forms a limiting part 4132. The limiting part 4132 is used to prevent the abutment rod 413 from slipping off the abutment block 411 due to gravity. The positioning part 4131 is a block structure made of silicone. The spring 412 is disposed between the positioning part 4131 and the abutment block 411. If the first positioning rod 41 directly abuts against the polished outer wall surface of the pipe, the first positioning rod 41 may leave scratches on the outer wall surface of the pipe. Therefore, in this embodiment, the positioning part 4131 is provided to prevent damage to the polished pipe. When the first positioning rod 41 is threadedly connected to the first fixing frame 1 or the second fixing frame 2, the first positioning rod 41 can push the abutment block 411, spring 412 and abutment rod 413 to move towards the pipe. When the positioning part 4131 formed by the abutment rod 413 contacts the outer wall surface of the pipe, the spring 412 will be gradually compressed. After the spring 412 is compressed, it will apply a thrust to the positioning part 4131, causing the positioning part 4131 to deform. The area of the positioning part 4131 in contact with the outer wall surface of the pipe will increase, thereby increasing the contact area with the outer wall surface of the pipe and fixing the pipe. Multiple springs 412 and abutment rods 413 are provided on the abutment block 411. The spring 412 is provided to reduce the local concentrated stress of the first positioning rod 41 on the pipe, and to disperse the pressure by multiple abutment rods 413. This is suitable for uneven surfaces or some thin-walled pipes and can prevent indentation of the pipe. When the spring 412 is compressed, multiple abutment rods 413 adapt to the undulations of the pipe surface to ensure uniform force distribution.
[0037] Specifically, the first positioning rod 41 is rotatably connected to the abutment block 411, allowing the first positioning rod 41 to rotate relative to the abutment block 411. The abutment block 411 has a mounting hole 4111 for the first positioning rod 41 to be inserted. The fixing mechanism also includes a fixing plate 7. A fixing hole 71 is formed on the fixing plate 7. A threaded hole 414 is formed at one end of the first positioning rod 41. The first positioning rod 41 passes through the mounting hole 4111, and a bolt passes through the fixing hole 71 and is threadedly connected to the mounting hole 4111. The nut formed by the bolt abuts against the fixing plate 7 to prevent the fixing plate 7 from falling off. If the end of the first positioning rod 41 is fixedly connected to the abutment block 411, the abutment block 411, the abutment rod 413, and the spring 412 will rotate around the center line of the first positioning rod 41. This rotation will affect the pipe fixing effect. For example, only a few of the multiple positioning parts 4131 on the multiple abutment rods 413 will abut against the outer wall of the pipe, while the remaining positioning parts 4131 will be suspended, preventing complete pipe fixing. Therefore, in this embodiment, the first positioning rod 41 is rotatably connected to the abutment block 411.
[0038] Specifically, the positioning component 4 also includes a second positioning rod 42 and a third positioning rod 43. The second positioning rod 42 and the third positioning rod 43 are shown in the attached drawings. Figure 2 The second positioning rod 42 and the third positioning rod 43 support both sides of the support plate 3. The second positioning rod 42 is threadedly connected to the first fixing frame 1 or the second fixing frame 2, and the third positioning rod 43 is threadedly connected to the first fixing frame 1 or the second fixing frame 2. When the worker polishes the pipe placed on the support plate 3, the pipe will produce slight shaking or vibration, and the support plate 3 located below the pipe will also shake or vibrate. When one end of the second positioning rod 42 and the third positioning rod 43 abuts against the support plate 3, the second positioning rod 42 and the third positioning rod 43 can simultaneously apply pressure to both sides of the support plate 3, forming a symmetrical clamping force on the support plate 3, suppressing the lateral displacement of the support plate 3, preventing the support plate 3 from shaking or vibrating, and thus providing better support for the pipe.
[0039] Specifically, one end of both the second positioning rod 42 and the third positioning rod 43 forms an abutment portion 431. The abutment portion 431 has a plate-like structure. The abutment portion 431 forms a first abutment surface 4311 and a second abutment surface 4312; the first abutment surface 4311 is parallel to the first support portion 31 and the second support portion 32, and the second abutment surface 4312 is parallel to the support plate 3. The first abutment surface 4311 is in contact with the first support portion 31 or the second support portion 32, and the second abutment surface 4312 is in contact with the support plate 3, increasing the contact area between the second positioning rod 42 and the third positioning rod 43 and the support plate 3, thereby providing better support for the support plate 3.
[0040] Specifically, both the first fixing bracket 1 and the second fixing bracket 2 form a first positioning hole 21 for the second positioning rod 42 to pass through. Both the first fixing bracket 1 and the second fixing bracket 2 form a second positioning hole 22 for the third positioning rod 43 to pass through. See the attached drawings for details. Figure 5 The axes of the first positioning hole 21 and the second positioning hole 22 coincide. Multiple first positioning holes 21 and second positioning holes 22 are provided on the first fixing bracket 1 and the second fixing bracket 2 in a direction parallel to the horizontal plane. When polishing the outer wall of the pipe, the worker may feel that the distance between the pipe and the ground is too close, that is, too far relative to the distance of the human hand. The worker may need to bend over to polish the pipe, which can easily lead to fatigue. Therefore, multiple first positioning holes 21 and second positioning holes 22 are provided on the first fixing bracket 1 and the second fixing bracket 2 to allow the worker to adjust the distance between the pipe and the ground, so that the worker can polish the pipe without bending over.
[0041] Specifically, the bottoms of the first fixing bracket 1 and the second fixing bracket 2 are connected by a connecting seat 5. A first guide rail and a second guide rail are provided on the connecting seat 5. The bottom of the first fixing bracket 1 is slidably connected to the first and second guide rails, and the bottom of the second fixing bracket 2 is also slidably connected to the first and second guide rails. In cases where there are depressions or protrusions on the pipe surface, the first fixing bracket 1 and the second fixing bracket 2 can be controlled to slide on the connecting seat 5 to avoid the depressions or protrusions, thus preventing the positioning part 4131 formed on the abutment rod 413 from deforming and still failing to fully contact the outer wall of the pipe.
[0042] Specifically, the fixing mechanism also includes: support blocks 6. Two support blocks 6 are provided. Support blocks 6 are used to support both ends of the support plate 3. When some pipes with thick walls are placed on the support plate 3, due to the large weight of the pipes themselves, the second positioning rods 42 and the third positioning rods 43 set on both sides of the support plate 3 may not be able to effectively support the pipes. Therefore, support blocks 6 are set at both ends of the support plate 3 to provide auxiliary support for the pipes.
[0043] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
