Technical Field

[0001] This utility model relates to the field of pipe beveling machine locking technology, specifically, to a pipe beveling machine locking device. Background Technology

[0002] Pipe beveling machines are specialized tools for beveling pipes or plates at the welding front end. They solve the shortcomings of flame cutting, grinding, and other processes, such as non-standard angles, rough bevels, and high noise. They have the advantages of simple operation, standard angles, and smooth surfaces. When processing pipes, the beveling machine first needs to fix the pipe.

[0003] Existing pipe beveling machine locking devices typically use multiple clamping components to clamp the pipe sidewall simultaneously, thereby increasing the contact area between the device and the pipe and achieving the purpose of firmly locking the pipe. However, in actual production, there is a problem that workers need to manually adjust multiple clamping components, which is quite inconvenient.

[0004] Therefore, this utility model provides a locking device for a pipe beveling machine. Utility Model Content

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1 to 6As shown, a pipe beveling machine locking device according to an embodiment of the present invention includes a limiting platform 1, a fixed shaft 11 fixedly connected to the side wall of the limiting platform 1; a slide cylinder 12 slidably connected to the side wall of the fixed shaft 11; a rotating block 18 rotatably connected to the side wall of the slide cylinder 12, and limiting blocks 17 rotatably connected to the side walls of multiple rotating blocks 18; multiple limiting blocks 17 are arranged in a circumferential array; a clamping block 19 is fixedly connected to the end of the limiting block 17; a push block 13 is fixedly connected to the side wall of the slide cylinder 12, and two push blocks 13 are arranged correspondingly; a hydraulic cylinder 14 is provided on the side wall of the push block 13; a hydraulic platform 15 is fixedly connected to the bottom of the two hydraulic cylinders 14 respectively, and the two hydraulic platforms 15 are fixedly connected to the side wall of the support platform 16 respectively; during operation, the operator can place the pipe to be locked between the multiple clamping blocks 19, and lock the pipe between the multiple clamping blocks 19 by simultaneously driving the two hydraulic cylinders 14. During the process, each When the hydraulic cylinder 14, which is fixed to the top of the hydraulic platform 15, is driven, the push block 13 is fixedly connected to both the slide cylinder 12 and the output end of the hydraulic cylinder 14. The slide cylinder 12 and the push block 13 will slide on the side wall of the fixed shaft 11 under the action of the hydraulic cylinder 14. Subsequently, since the slide cylinder 12 is rotatably connected to the limit block 17 by a rotating block 18, and the limit block 17 is limited by the limit platform 1, the multiple limit blocks 17 will drive the corresponding clamping blocks 19 to move along with the movement of the slide cylinder 12, and clamp the pipe placed between the multiple clamping blocks 19. The support platform 16 serves to fix the hydraulic cylinder 14. Through the above structure, the hydraulic cylinder 14 drives the slide cylinder 12, thereby clamping the multiple clamping blocks 19 on the side wall of the pipe. This facilitates the automatic and rapid locking of the pipe, provides convenience for the pipe locking action of the workers, reduces the physical exertion of the workers, and improves work efficiency.

[0034] like Figures 1 to 4As shown, a buffer plate 2 is provided on the side wall of the limiting platform 1; a first limiting rod 21 is fixedly connected to the side wall of the buffer plate 2, and multiple first limiting rods 21 are arranged in a circumferential array; a first buffer spring 22 is fixedly connected between the limiting platform 1 and the buffer plate 2; a second buffer spring 23 is fixedly connected between the limiting platform 1 and the buffer plate 2; a buffer platform 24 is fixedly connected to the side wall of the limiting platform 1; a fixed panel 25 is fixedly connected to the side wall of the limiting platform 1, and the fixed panel 25 is fixedly connected to the support platform 16; during operation, the fixed panel 25 fixed to the side wall of the support platform 16 is simultaneously fixedly connected to the limiting platform 1, and the support platform 16 can provide support for the limiting platform 1 through the fixed panel 25. During the process of the operator placing the pipe between multiple clamping blocks 19, whenever the pipe is about to hit the side wall of the limiting platform 1, the pipe will first contact the buffer plate 2. At this time, the force of the pipe will act on the buffer. On plate 2, since a first buffer spring 22 and a second buffer spring 23 are fixedly connected between buffer plate 2 and limiting platform 1, after buffer plate 2 is impacted by the pipeline, the stress will be further transmitted to the first buffer spring 22 and multiple second buffer springs 23, causing it to contract until buffer plate 2 contacts the side wall of buffer platform 24. When the pipeline is stabilized or the pipeline processing is completed, the second buffer spring 23 and multiple first buffer springs 22 will release the elastic force to return buffer plate 2 to its position. Among them, multiple first limiting rods 21 fixed on the side wall of buffer plate 2 can restrict the posture of buffer plate 2. Through the above structure, the buffer plate 2 is set to contact the side wall of the pipeline, thereby avoiding the pipeline from impacting the side wall of the device during the locking process, enhancing the risk resistance of the device, which is conducive to protecting the structural stability of the device, reducing the maintenance requirements of the device, and extending the service life of the device.

[0035] like Figure 3 and Figure 5 As shown, a second limiting rod 3 is fixedly connected to the side wall of the push block 13, and the two second limiting rods 3 are arranged correspondingly; a limiting frame 31 is fixedly connected to the side wall of the support platform 16, and the two limiting frames 31 are respectively arranged to correspond to the size and position of the second limiting rod 3; during operation, the second limiting rod 3 fixed to the side wall of the push block 13 is slidably connected to the inside of the limiting frame 31, and the two limiting frames 31 are respectively fixedly connected to the support platform 16. The second limiting rod 3 and the limiting frame 31 can restrict the push block 13 by contact; through the above structure, the second limiting rod 3 and the limiting frame 31 restrict the posture of the push block 13, thereby preventing it from tilting during the force process, enhancing the stability of the device, which is conducive to extending the service life of the device and reducing maintenance requirements.

[0036] like Figure 3As shown, a fixing ring 4 is fixedly connected to the side wall of the limiting platform 1; a return spring 41 is fixedly connected to the side wall of the fixing ring 4, and the end of the return spring 41 away from the fixing ring 4 is fixedly connected to the side wall of the slide cylinder 12; during operation, whenever the device stops working, the return spring 41 fixed between the fixing ring 4 and the slide cylinder 12 can apply a pulling force to the fixing ring 4 and the slide cylinder 12 by its own elastic force, keeping their positions stable, thereby preventing the limiting block 17 and the clamping block 19 from moving under their own gravity; through the above structure, the fixing ring 4 and the return spring 41 are set so that the relative position of the slide cylinder 12 and the limiting platform 1 is constant when the device stops working, thereby preventing multiple limiting blocks 17 and clamping blocks 19 from moving under their own gravity, which is conducive to maintaining the position stability of multiple clamping blocks 19 and providing convenience for workers to lock the pipes.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, a clamping gasket 5 is provided on the side wall of the clamping block 19; a fixing stud 51 is fixedly connected to the side wall of the clamping block 19, and multiple fixing studs 51 are arranged in a corresponding manner; the clamping gasket 5 is made of rubber; during operation, the operator can use the fixing studs 51 to install the rubber clamping gasket 5 on the side wall of the clamping block 19, so that the clamping gasket 5 replaces the clamping block 19 to contact the side wall of the pipe; through the above structure, the clamping gasket 5 made of rubber replaces the clamping block 19 to contact the side wall of the pipe, so that it can make a tight contact with the side wall of the pipe through deformation under force, which is beneficial to optimize the contact relationship between the device and the pipe and improve the stability of the pipe.

[0038] like Figure 6 As shown, a buffer pad 6 is fixed to the side wall of the fixed panel 25, and the buffer pad 6 is made of rubber. During operation, whenever the buffer plate 2 is subjected to the impact of the pipeline, multiple first limit rods 21 will move synchronously with the buffer plate 2. The buffer pad 6, which is fixed to the side wall of the fixed panel 25 and is made of rubber, can stop the movement of the buffer plate 2 and the first limit rod 21 by contacting the first limit rod 21, thereby preventing the first buffer spring 22 and multiple second buffer springs 23 from being over-compressed. Through the above structure, the buffer pad 6 stops the movement of the buffer plate 2 and the first limit rod 21, thereby preventing the first buffer spring 22 and multiple second buffer springs 23 fixed between the limit platform 1 and the buffer plate 2 from being over-compressed. This helps to protect the structural stability of the first buffer spring 22 and the second buffer spring 23 and extend their service life.

[0039] like Figure 3As shown, reinforcing blocks 7 are fixedly connected to the side wall of the slide cylinder 12, and multiple reinforcing blocks 7 are arranged correspondingly. During operation, the multiple reinforcing blocks 7 fixed to the side wall of the slide cylinder 12 increase the surface structure of the slide cylinder 12 and enhance its structural strength. Through the above structure, the reinforcing blocks 7 enhance the structural strength of the slide cylinder 12, thereby preventing the slide cylinder 12 from deforming under stress, which is beneficial to enhancing the structural stability of the device and extending its service life.

[0040] like Figure 1 and Figure 5 As shown, a connecting block 8 is fixedly connected to the side wall of the support platform 16. During operation, the connecting block 8 fixed between the corresponding side walls of the support platform 16 connects the two parts of the support platform 16 together. Through the above structure, the connecting block 8 connects the two parts of the support platform 16, thereby preventing them from shifting during operation and helping to maintain the structural stability of the device.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the limiting platform 1, fixed shaft 11, slide cylinder 12, limiting block 17, rotating block 18, and clamping block 19 are made of stainless steel. During operation, the use of stainless steel in the limiting platform 1, fixed shaft 11, slide cylinder 12, limiting block 17, rotating block 18, and clamping block 19 allows them to leverage the advantages of high structural strength and strong corrosion resistance. The use of stainless steel in the limiting platform 1, fixed shaft 11, slide cylinder 12, limiting block 17, rotating block 18, and clamping block 19 enhances their structural strength and corrosion resistance, which helps reduce maintenance requirements and extend the service life of the device.

[0042] like Figure 5 As shown, the surface of the support platform 16 is coated with an anti-rust coating; during operation, the anti-rust coating can increase the surface oxidation resistance of the support platform 16; through the above, the surface of the support platform 16 is coated with an anti-rust coating to enhance its surface oxidation resistance, thereby slowing down its corrosion rate.

[0043] During operation, the operator can place the pipe to be locked between multiple clamping blocks 19 and lock it between the clamping blocks 19 by simultaneously driving two hydraulic cylinders 14. During this process, whenever the hydraulic cylinder 14, fixed to the top of the hydraulic platform 15, is driven, the push block 13, being fixedly connected to both the slide cylinder 12 and the output end of the hydraulic cylinder 14, will slide on the side wall of the fixed shaft 11 under the action of the hydraulic cylinder 14. Subsequently, because a rotating block 18 is rotatably connected between the slide cylinder 12 and the limiting block 17, and the limiting block 17 is limited by the limiting platform 1, the multiple limiting blocks 17 will drive the corresponding clamping blocks 19 to move along with the movement of the slide cylinder 12, thus locking the pipe placed between the multiple clamping blocks 19. The pipe is clamped, in which the support platform 16 serves to fix the hydraulic cylinder 14. The fixing panel 25, which is fixed to the side wall of the support platform 16, is also fixed to the limiting platform 1. The support platform 16 can provide support for the limiting platform 1 through the fixing panel 25. During the process of the operator placing the pipe between multiple clamping blocks 19, whenever the pipe is about to hit the side wall of the limiting platform 1, the pipe will first come into contact with the buffer plate 2. At this time, the force of the pipe will act on the buffer plate 2. Since the first buffer spring 22 and the second buffer spring 23 are fixed between the buffer plate 2 and the limiting platform 1, after the buffer plate 2 is subjected to the impact from the pipe, it will further transmit the stress to the first buffer spring 22 and the multiple second buffer springs 23, causing them to contract until the pressure is released. The impact plate 2 contacts the side wall of the buffer platform 24. After the pipeline stabilizes or is processed, the second buffer spring 23 and multiple first buffer springs 22 release their elastic force to return the buffer plate 2 to its original position. Multiple first limiting rods 21 fixed to the side wall of the buffer plate 2 can restrict the posture of the buffer plate 2. The second limiting rod 3 fixed to the side wall of the push block 13 is slidably connected inside the limiting frame 31, and the two limiting frames 31 are respectively fixed to the support platform 16. The second limiting rod 3 and the limiting frame 31 can restrict the push block 13 through contact. Whenever the device stops working, the return spring 41 fixed between the fixed ring 4 and the slide cylinder 12 can apply tension to the fixed ring 4 and the slide cylinder 12 using its own elastic force to maintain their stable positions. To prevent the limiting block 17 and clamping block 19 from moving under their own weight, the operator can use the fixing stud 51 to install the rubber clamping pad 5 on the side wall of the clamping block 19, so that the clamping pad 5 replaces the clamping block 19 in contact with the side wall of the pipe. Whenever the buffer plate 2 is impacted by the pipe, the multiple first limiting rods 21 will move synchronously with the buffer plate 2. The rubber buffer pad 6, which is fixed to the side wall of the fixed panel 25, can stop the movement of the buffer plate 2 and the first limiting rods 21 by contacting the first limiting rods 21, thereby preventing the first buffer spring 22 and multiple second buffer springs 23 from being over-compressed. The multiple reinforcing blocks 7 fixed to the side wall of the slide cylinder 12 increase the surface structure of the slide cylinder 12.The structural strength of the slide cylinder 12 is enhanced. The connecting block 8, fixed between the corresponding side walls of the support platform 16, connects the two parts of the support platform 16 together. The use of stainless steel for the limiting platform 1, fixed shaft 11, slide cylinder 12, limiting block 17, rotating block 18, and clamping block 19 leverages the advantages of high structural strength and strong corrosion resistance of stainless steel. The application of an anti-rust coating increases the surface oxidation resistance of the support platform 16.
