Description

Technical Field

[0001] This utility model relates to the field of tubular clamp technology, and in particular to a clamp for tubular work. Background Technology

[0002] During the processing and use of tubular structures, clamps are generally required for stable clamping to ensure stable installation. Since the surface of the tubular structure is curved, ordinary flat clamps cannot stably clamp the tubular structure.

[0003] Therefore, a clamp for tubular work is proposed to stably hold tubular structures.

[0004] Existing tubular work clamps are prone to damaging or crushing the ends of tubular structures when used to clamp them, failing to provide safe and stable clamping. Furthermore, the clamped position of the tubular structure is relatively fixed during processing or use, making it inconvenient to flexibly adjust the clamping height. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that, when clamping the end face of a tubular structure, easily damage or crush the port of the tubular structure, failing to provide a safe and stable clamping for the tubular structure, and to propose a tubular working clamp.

[0008] Furthermore, the base driving mechanism includes a first driving rod and a second driving rod. A connecting plate is fixed to the outer end of the cylinder, and a connecting block is fixed to the outer side of the connecting plate. The connecting block is hinged to one end of the first driving rod, and the other end of the first driving rod is hinged to one end of the second driving rod. A guide block is fixed to the other end of the second driving rod.

[0009] Furthermore, the surface of the third mounting plate has a guide groove, the guide block slides through the guide groove, a first limiting plate is fixed on the surface of the guide block and at the position inside the guide groove, a first connecting hole is opened at the outer end of the guide block, a second connecting hole is opened on the surface of the moving block, a first bolt is inserted into the second connecting hole and the first connecting hole, and the telescopic rod slides through the reserved hole in the middle of the third mounting plate.

[0010] Furthermore, the base has insertion slots at both ends of its surface, and the bottom end of the first mounting plate is slidably inserted into the insertion slot. The insertion slot has a third connecting hole at both ends. The third connecting hole is a threaded hole structure, and a second bolt passes through the inside of the third connecting hole. The inner end of the second bolt abuts against both sides of the first mounting plate.

[0011] Furthermore, a first sliding groove is formed in the middle of the surface of the first mounting plate, and second sliding grooves are provided on both sides of the first sliding groove. Guide plates are fixed at both ends of the outer side of the second mounting plate. The sliding plate is slidably inserted into the first sliding groove. A rotating hole is formed in the middle of the sliding plate. A rotating rod rotates through the inside of the rotating hole. A motor is installed at the top of the rotating rod.

[0013] Furthermore, both the moving block and the clamping block are fan-shaped structures and are vertically arranged; the guide block is a rectangular groove structure and is horizontally arranged; the connecting plate is a circular plate structure and is vertically arranged; the guide groove is a rectangular groove structure, and the four guide grooves are arranged in a cross shape; and the first connecting hole is a threaded hole structure and is horizontally arranged.

[0016] 1. The clamping mechanism of this utility model is mounted on the base via a lifting and adjusting mechanism. In the clamping mechanism, the cylinder is connected to the clamping block via a driving mechanism. Therefore, when clamping the tubular structure, the cylinder drives the telescopic rod to retract, thereby pulling the third mounting plate closer to the cylinder via the driving mechanism. Through the guide groove and the third mounting plate guiding and limiting the guide block, the moving block and the clamping block move along the guide groove and approach each other, so that one end of the tubular structure abuts against the outside of the moving block, and the inner wall of the tubular structure is engaged with the outside of the engaging block. At the same time, the cylinder drives the telescopic rod to extend, and pushes the third mounting plate to move via the driving mechanism. Through the guide groove and the third mounting plate guiding and limiting the guide block, the moving block and the clamping block move along the guide groove and separate from each other. Therefore, one end of the tubular structure can be firmly connected, avoiding damage or crushing of the end of the tubular structure, and facilitating the disassembly and installation of the tubular structure.

[0017] 2. This utility model is equipped with a lifting and adjusting mechanism on the base. The clamping mechanism is inserted into the first sliding groove and the second sliding groove on the side of the first mounting plate through the sliding plate and the guide plate. The rotating rod is driven by the motor to move forward and backward, so that the height of the clamping mechanism can be adjusted. Thus, the tubular structure can be clamped and placed at different heights for flexible application. Attached Figure Description

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The figure shows a tubular working clamp, including a base 1, a first mounting plate 3 mounted on the top of the base 1, a lifting adjustment mechanism mounted on the side of the first mounting plate 3, and a clamping mechanism mounted on the side of the lifting adjustment mechanism.

[0027] The base 1 has insertion slots 17 at both ends of its surface. The bottom end of the first mounting plate 3 is slidably inserted into the insertion slots 17. The insertion slots 17 have third connecting holes 16 at both ends. The third connecting holes 16 are threaded holes. A second bolt 2 passes through the inside of the third connecting hole 16. The inner end of the second bolt 2 abuts against both sides of the first mounting plate 3.

[0028] Furthermore, the clamping mechanism includes a cylinder 5, a drive mechanism, a third mounting plate 10, and a clamping block 12. The cylinder 5 is mounted on the side of the second mounting plate 4, and a telescopic rod 25 is connected to the outer end of the cylinder 5. The drive mechanism is connected to the outer end of the cylinder 5. The third mounting plate 10 is connected to the outer end of the drive mechanism and is fastened to the telescopic rod 25.

[0029] The base driving mechanism includes a first driving rod 23 and a second driving rod 21. A connecting plate 14 is fixed to the outer end of the cylinder 5.

The other end of the first driving rod 23 is hinged to one end of the second driving rod 21. A guide block 22 is fixed to the other end of the second driving rod 21.

[0030] The surface of the third mounting plate 10 has a guide groove 13, the guide block 22 slides through the guide groove 13, a first limiting plate 20 is fixed on the surface of the guide block 22 and at the position inside the guide groove 13, a first connecting hole 29 is opened at the outer end of the guide block 22, a second connecting hole 18 is opened on the surface of the moving block 11, a first bolt 28 is inserted into the second connecting hole 18 and the first connecting hole 29, and the telescopic rod 25 slides through the reserved hole in the middle of the third mounting plate 10.

[0031] The clamping mechanism is mounted on the base 1 via a lifting and adjusting mechanism. In the clamping mechanism, cylinder 5 is connected to clamping block 12 via a drive mechanism. Therefore, when clamping the tubular structure, cylinder 5 drives the telescopic rod 25 to retract, thereby pulling the third mounting plate 10 closer to cylinder 5 via the drive mechanism. The guide groove 13 and the third mounting plate 10 guide and limit the guide block 22, causing the moving block 11 and clamping block 12 to move along the guide groove 13 and approach each other, bringing one end of the tubular structure abutting against it. The outer side of the moving block 11 and the inner wall of the tubular structure are engaged with the outer side of the clamping block 12. At the same time, the cylinder 5 drives the telescopic rod 25 to extend and pushes the third mounting plate 10 to move through the drive mechanism. The guide block 22 is guided and limited by the guide groove 13 and the third mounting plate 10, so that the moving block 11 and the clamping block 12 move along the guide groove 13 and separate from each other. Therefore, one end of the tubular structure can be fastened to avoid the end of the tubular structure being damaged or crushed, and the tubular structure can be easily disassembled and installed.

[0032] The base 1 is horizontally arranged, the first mounting plate 3 and the second mounting plate 4 are both vertically arranged, the cylinder 5 is horizontally arranged, the third mounting plate 10 is a circular plate structure and is vertically arranged, and the reinforcing rod 9 is horizontally arranged.

The connecting plate 14 is a circular plate structure and is vertically arranged. The guide groove 13 is a rectangular groove structure, and the four guide grooves 13 are arranged in a cross shape. The first connecting hole 29 is a threaded hole structure and is horizontally arranged.

[0034] In detail, the lifting and adjusting mechanism includes a second mounting plate 4 and a sliding plate 15. The sliding plate 15 is fixed on the outside of the second mounting plate 4, and the second mounting plate 4 is slidably mounted on the inside of the first mounting plate 3.

[0035] The first mounting plate 3 has a first sliding groove 8 in the middle of its surface, and second sliding grooves 6 are provided on both sides of the first sliding groove 8. Guide plates 26 are fixed at both ends of the outer side of the second mounting plate 4. The sliding plate 15 is slidably inserted into the first sliding groove 8. The sliding plate 15 has a rotating hole 27 in the middle. A rotating rod 19 rotates through the inside of the rotating hole 27. A motor 7 is installed at the top of the rotating rod 19. The guide plate 26 slides through the second sliding groove 6.

[0036] A lifting and adjusting mechanism is set on the base 1. The clamping mechanism is inserted into the first sliding groove 8 and the second sliding groove 6 on the side of the first mounting plate 3 through the sliding plate 15 and the guide plate 26. The rotating rod 19 is driven by the motor 7 to move forward and backward, so that the height of the clamping mechanism can be adjusted. Thus, the tubular structure can be clamped and placed at different heights for flexible application.

[0037] Both the first sliding groove 8 and the second sliding groove 6 are rectangular structures and are vertically arranged. The rotating hole 27 is a threaded hole structure, and the rotating rod 19 is a threaded rod structure and is vertically arranged, and is rotatably connected to the first mounting plate 3.

[0038] Working principle: The clamping mechanism is mounted on the base 1 via a lifting and adjusting mechanism. In the clamping mechanism, the cylinder 5 is connected to the clamping block 12 via a drive mechanism. Therefore, when clamping the tubular structure, the cylinder 5 drives the telescopic rod 25 to retract, thereby pulling the third mounting plate 10 closer to the cylinder 5 via the drive mechanism. Through the guide groove 13 and the third mounting plate 10 guiding and limiting the guide block 22, the moving block 11 and the clamping block 12 move along the guide groove 13 and move closer to each other, pressing one end of the tubular structure against the guide. The inner wall of the tubular structure is attached to the outer side of the moving block 11, and the inner wall of the tubular structure is engaged with the outer side of the clamping block 12. At the same time, the cylinder 5 drives the telescopic rod 25 to extend, and pushes the third mounting plate 10 to move through the drive mechanism. The guide block 22 is guided and limited by the guide groove 13 and the third mounting plate 10, so that the moving block 11 and the clamping block 12 move along the guide groove 13 and separate from each other. Therefore, one end of the tubular structure can be fastened, avoiding damage or crushing of the end of the tubular structure, and facilitating the disassembly and installation of the tubular structure.

[0039] A lifting and adjusting mechanism is set on the base 1. The clamping mechanism is inserted into the first sliding groove 8 and the second sliding groove 6 on the side of the first mounting plate 3 through the sliding plate 15 and the guide plate 26. The rotating rod 19 is driven by the motor 7 to move forward and backward, so that the height of the clamping mechanism can be adjusted. Thus, the tubular structure can be clamped and placed at different heights for flexible application.
