Description

Technical Field

[0001] This utility model relates to the field of pipe and profile cutting technology, and in particular to a pipe and profile rear end clamping device. Background Technology

[0002] Currently, in metal processing, aluminum profile cutting, and pipe blanking, it is usually necessary to clamp and fix the tail of the pipe or profile to ensure processing accuracy and safety. Existing clamping mechanisms mostly adopt a symmetrical structure, using a motor or cylinder to lower the upper clamping plate to cooperate with the lower clamping plate for clamping and fixation. However, in practical applications, when the tail of the profile is long or heavy, its free end is prone to drooping due to its own weight, causing interference or collision with the lower clamping plate when entering the clamping area. This not only affects clamping accuracy but may also cause scratches on the workpiece surface or deformation of the clamp.

[0003] Secondly, in some traditional clamping mechanisms, the lower clamping plate is fixed in position, and clamping is achieved only by the downward pressing action of the upper clamping plate. This results in the clamping surface not being able to fully fit when the end of the pipe is slightly tilted, causing unstable clamping or uneven force, which affects the accuracy of subsequent cutting and feeding, and may even cause vibration or slippage during processing.

[0004] Furthermore, existing clamping structures are mostly single linear drive mechanisms, whose clamping process involves simple movements and poor coordination, making it impossible to achieve dynamic process control of "support first, then clamp". For pipes and profiles of different diameters or shapes, it is usually necessary to manually adjust the clamp spacing or replace the clamping plate structure, which is cumbersome, inefficient, and not conducive to the continuous operation of automated production lines.

[0005] Therefore, there is an urgent need to provide a pipe and profile rear end clamping device with a reasonable structure, controllable action sequence, and stable and reliable clamping process. This device can first lift and support the pipe during the clamping process, and then achieve coordinated clamping by the upper and lower clamping plates to avoid interference and sagging problems under traditional structures, thereby improving processing accuracy and automation adaptability. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pipe and profile rear end clamping device.

[0007] The purpose of this utility model is achieved as follows: a pipe and profile rear end clamping device includes a driving mechanism, a connecting member is provided at the front end of the driving mechanism, an upper connecting plate and a lower connecting plate are rotatably provided on the connecting member, the upper connecting plate and the lower connecting plate move under the action of the driving mechanism, the driving mechanism drives the front side of the lower connecting plate to rotate upward first, and then drives the front side of the upper connecting plate to rotate downward, an upper clamping plate is detachably provided at the front end of the upper connecting plate, and a lower clamping plate is provided at the front end of the lower connecting plate.

[0008] A connecting shaft is rotatably installed through the middle of the upper and lower connecting plates, and a connecting member is rotatably installed through the connecting shaft. The upper and lower connecting plates are rotatably connected via the connecting shaft and the connecting member. A guide block is provided at the output end of the drive mechanism. The drive mechanism drives the guide block to move back and forth. The left and right sides of the guide block are connected to the lower and upper connecting plates respectively. The drive mechanism drives the upper and lower connecting plates to rotate around the connecting shaft through the guide block.

[0009] The guide block has a lower guide groove and an upper guide groove on its left and right sides, respectively. A lower guide rod is located on the inner side of the lower connecting plate, within the lower guide groove, and moves along it. An upper guide rod is located on the inner side of the upper connecting plate, within the upper guide groove, and moves along it. The front of the lower guide groove is a forward-and-upward inclined groove, while the rear is a horizontal groove. The front of the upper guide groove is a horizontal groove, while the rear is a backward-and-upward inclined groove. Housings are provided on both the left and right sides of the connector.

[0010] In use, the drive mechanism is fixed on the profile cutting bracket, and the tail of the profile is placed between the upper clamping plate and the lower clamping plate. By controlling the drive mechanism to extend forward (the drive mechanism is a telescopic mechanism such as an electric cylinder or a pneumatic cylinder), the drive mechanism drives the front side of the lower connecting plate to rotate upward first, and then drives the front side of the upper connecting plate to rotate downward. Thus, the lower clamping plate first lifts and supports the pipe and profile, and then the upper clamping plate clamps the pipe and profile together with the lower clamping plate.

[0011] The drive mechanism extends forward, causing the guide block to move forward. As the guide block moves forward, the upper guide rod on the upper connecting plate moves horizontally in front of the upper guide groove, without rotating the upper connecting plate. Meanwhile, the lower guide rod on the lower connecting plate moves downward in front of the lower guide groove, causing the lower connecting plate to rotate around the connecting shaft. This, in turn, causes the front of the lower connecting plate to rotate upward, lifting the lower clamping plate on the lower connecting plate to support the profile, until the lower guide rod on the lower connecting plate is located in the horizontal groove at the rear of the lower guide groove. The guide block continues to move forward, with the lower guide rod moving within the horizontal groove at the rear of the lower guide groove, without rotating the lower guide plate. At this point, the upper guide rod on the upper guide plate is located in the upward-sloping groove structure on the rear side of the upper guide groove, causing the upper guide plate to rotate along the connecting shaft, and causing the front end of the upper guide plate to rotate downward. This allows the upper clamping plate on the upper guide plate to work with the lower clamping plate to clamp the pipe or profile. The above technical solution can first place the pipe or profile between the upper and lower clamping plates, and then move the lower clamping plate upward to support it. This avoids the traditional method of fixing the lower clamping plate, where the rear end of the profile tilts downward or bends slightly due to its own weight, causing the pipe or profile to interfere with the lower clamping plate when it moves toward the clamping mechanism, i.e., the lower clamping plate collides with the lower part of the profile.

[0012] Beneficial effects: This utility model has the following technical effects when used:

[0013] This application achieves step-by-step movement and coordinated clamping of the upper and lower clamping plates by setting rotatable upper and lower connecting plates on the connector, and controlling their rotation by a drive mechanism through the cooperation of guide blocks, guide grooves, and guide rods. When the drive mechanism extends forward, it first drives the front side of the lower connecting plate to rotate upward, so that the lower clamping plate lifts and supports the tail of the pipe or profile. Then, it drives the front side of the upper connecting plate to rotate downward, so that the upper and lower clamping plates cooperate to clamp the pipe or profile, thus realizing the motion logic of "support first, then clamp". This action sequence can effectively prevent the profile from sagging or shifting due to gravity before clamping, avoid the problem of collision and interference between the tail end of the profile and the lower clamping plate, and improve the stability and accuracy of clamping.

[0014] Secondly, this application features differentiated upper and lower guide grooves on both sides of the guide block. The lower guide groove has a forward-upward inclined groove on the front side, while the upper guide groove has a backward-upward inclined groove on the rear side. This makes the rotation trajectory of the upper and lower connecting plates under different stages of force controllable and smooth, ensuring stable and reliable movement and reducing mechanism jamming and impact. The matching connecting shaft allows the upper and lower connecting plates to rotate around a unified axis, resulting in coordinated overall transmission, a compact structure, and convenient assembly.

[0015] Furthermore, the clamping mechanism of this application can complete complex rotation and clamping actions through linear drive by a drive mechanism (such as an electric cylinder or a pneumatic cylinder), without the need for complex coordination by an external control system, resulting in a simplified structure and smooth operation. This device is applicable to clamping various specifications of pipes and profiles, exhibiting good versatility and compatibility.

[0016] The pipe and profile rear end clamping device of this application can realize automated and step-by-step support and clamping operations during the clamping process, which significantly reduces the difficulty of manual adjustment, improves clamping accuracy and safety of use, and is suitable for various working environments such as profile cutting, conveying and processing positioning. It has good promotional value and practical effect. Attached Figure Description

[0029] Example 1, as Figure 1-10 As shown, the purpose of this utility model is to achieve a pipe and profile rear end clamping device, including a driving mechanism 1. A connecting member 2 is provided at the front end of the driving mechanism 1. An upper connecting plate 4 and a lower connecting plate 7 are rotatably provided on the connecting member 2. The upper connecting plate 4 and the lower connecting plate 7 move under the action of the driving mechanism 1. The driving mechanism 1 drives the front side of the lower connecting plate 7 to rotate upward first, and then drives the front side of the upper connecting plate 4 to rotate downward. An upper clamping plate 5 is detachably provided at the front end of the upper connecting plate 4, and a lower clamping plate 6 is provided at the front end of the lower connecting plate 7.

[0030] A connecting shaft 10 is rotatably connected through the middle of the upper connecting plate 4 and the lower connecting plate 7. The connecting shaft 10 rotatably passes through the connecting member 2, and the upper connecting plate 4 and the lower connecting plate 7 are rotatably connected to the connecting member 2 via the connecting shaft 10. A guide block 9 is provided at the output end of the drive mechanism 1. The drive mechanism 1 drives the guide block 9 to move back and forth. The left and right sides of the guide block 9 are connected to the lower connecting plate 7 and the upper connecting plate 4, respectively. The drive mechanism 1 drives the upper connecting plate 4 and the lower connecting plate 7 to rotate around the connecting shaft 10 via the guide block 9.

[0031] The guide block 9 has a lower guide groove 13 and an upper guide groove 12 on its left and right sides, respectively. A lower guide rod 8 is located on the inner side of the lower connecting plate 7, within the lower guide groove 13, and moves along the lower guide groove 13. An upper guide rod 11 is located on the inner side of the upper connecting plate 4, within the upper guide groove 12, and moves along the upper guide groove 12. The lower guide groove 13 has a forward-upward inclined groove structure on its front side and a horizontal groove structure on its rear side. The upper guide groove 12 has a horizontal groove structure on its front side and a backward-upward inclined groove structure on its rear side. The connector 2 has a housing 3 on both its left and right sides.

[0032] In use, the drive mechanism 1 is fixed on the profile cutting bracket, and the tail of the profile is placed between the upper clamping plate 5 and the lower clamping plate 6. By controlling the drive mechanism 1 to extend forward (the drive mechanism 1 is a telescopic mechanism such as an electric cylinder or a pneumatic cylinder), the drive mechanism 1 drives the front side of the lower connecting plate 7 to rotate upward first, and then drives the front side of the upper connecting plate 4 to rotate downward. Thus, the lower clamping plate 6 first lifts and supports the pipe and profile, and then the upper clamping plate 5 clamps the pipe and profile together with the lower clamping plate 6.

[0033] The drive mechanism 1 extends forward, driving the guide block 9 to move forward. When the guide block 9 moves forward, the upper guide rod 11 on the upper connecting plate 4 moves horizontally in front of the upper guide groove 12, and the upper connecting plate 4 does not rotate. Meanwhile, the lower guide rod 8 on the lower connecting plate 7 moves downward in front of the lower guide groove 13, and the lower connecting plate 7 rotates around the connecting shaft 10, thereby driving the front of the lower connecting plate 7 to rotate upward. The lower clamping plate 6 on the lower connecting plate 7 lifts upward to support the profile until the lower guide rod 8 on the lower connecting plate 7 is located in the horizontal groove at the rear of the lower guide groove 13. The guide block 9 continues to move forward, and the lower guide rod 8 moves within the horizontal groove at the rear of the lower guide groove 13, without rotating. At this time, the upper guide rod 11 on the upper guide plate is located in the rearward and upward inclined groove structure on the rear side of the upper guide groove 12, thereby driving the upper guide plate to rotate along the connecting shaft 10, driving the front end of the upper guide plate to rotate downward, so that the upper clamping plate 5 on the upper guide plate cooperates with the lower clamping plate 6 to clamp the pipe and profile. The above technical solution can first place the pipe or profile between the upper clamping plate 5 and the lower clamping plate 6, and then drive the lower clamping plate 6 to move upward to support it. This avoids the traditional method where the lower clamping plate 6 is fixed, and the rear end of the profile tilts downward or bends slightly due to its own weight, causing the pipe or profile to interfere with the lower clamping plate 6 when it moves toward the clamping mechanism, i.e., the lower clamping plate 6 collides with the lower part of the profile.
