Description

Technical Field

[0001] This utility model relates to the technical field of I-beam clamping equipment, specifically a clamping mechanism that can be used to cut multiple I-beams simultaneously. Background Technology

[0002] Often, I-beams are used as the basic components of supports, but before they can be processed into supports, the I-beams need to be cut. Reciprocating saws are a common cutting tool for I-beams.

[0003] When reciprocating saws cut, they need to use a clamping mechanism to hold the I-beams. Currently, the clamping mechanism used for cutting I-beams generally only uses two opposing hydraulic cylinders and clamping plates to hold the I-beams. However, it can usually only hold one I-beam at a time, resulting in low cutting efficiency. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping mechanism that can be used to cut multiple I-beams simultaneously, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for simultaneously cutting multiple I-beams, comprising a worktable, vertical plates, hydraulic cylinders, clamping plates, horizontal plates, screws, pressure plates, and bosses. Vertical plates are symmetrically arranged on the upper surface of the worktable. Hydraulic cylinders are arranged on the outer sides of each vertical plate. The piston rods of the hydraulic cylinders pass through the vertical plates and are connected to the clamping plates. A horizontal plate is arranged at the top of the inner side of the clamping plates. A threaded hole is formed through the horizontal plate in the vertical direction. A screw is connected to the threaded hole of the horizontal plate. A pressure plate is installed at the bottom of the screw via bolts. A slot is formed at the bottom of the inner side of the clamping plates. A boss is inserted into the clamping plate at the slot. Grooves are formed on both sides of the boss. The boss engages with the slot through the grooves. The boss and the lower surface of the clamping plates are slidably disposed on the upper surface of the worktable.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a clamping mechanism for simultaneously cutting multiple I-beams, including a worktable 1, a vertical plate 2, a hydraulic cylinder 3, a clamping plate 4, a horizontal plate 5, a screw 6, a pressure plate 7, and a boss 8. Several support frames 14 are provided at the bottom of the worktable 1 to raise and support the worktable. Vertical plates 2 are symmetrically arranged on the upper surface of the worktable 1. First reinforcing plates 12 are provided at both ends of the outer sides of the vertical plates 2, with their bottoms connected to the upper surface of the worktable 1 to ensure structural strength between the vertical plates 2 and the worktable 1. Hydraulic cylinders 3 are provided on the outer sides of the vertical plates 2, with their piston rods passing through the vertical plates 2 and connected to the clamping plates 4. A horizontal plate 5 is provided at the top of the inner side of the clamping plate 4. Several second reinforcing plates 13 are provided at the connection points between the horizontal plate 5 and the corresponding vertical plate 2 to ensure structural strength between the horizontal plate 5 and the vertical plate 2. The horizontal plate 5 has a threaded hole running through it vertically. A screw 6 is connected to the threaded hole of the horizontal plate 5. A handle 11 is provided at the top of the screw 6 to facilitate rotation of the screw 6, thereby facilitating the adjustment of the height of the pressure plate 7. The pressure plate 7 is installed at the bottom of the screw 6 by bolts. A countersunk hole is provided at the center of the pressure plate 7. The countersunk hole of the pressure plate 7 cooperates with the bolt to realize the connection and disassembly of the pressure plate 7 and the screw 6. At the same time, the countersunk hole prevents the bolt from protruding from the bottom of the pressure plate 7. A slot 9 is provided at the bottom of the inner side of the clamping plate 4. The slot 9 adopts a "convex" structure. A boss 8 is inserted into the clamping plate 4 at the slot 9. Grooves 10 are provided on both sides of the boss 8. The boss 8 cooperates with the slot 9 through the grooves 10. The boss 8 and the lower surface of the clamping plate 4 are slidably set on the upper surface of the workbench 1 to ensure the support of the boss 8. The top of the inner side of the boss 8 is provided with a bevel angle.

[0017] Installation method and operating principle: Weld the two upright plates 2 and the first reinforcing plates 12 on both sides to the workbench 1. Then, install the hydraulic cylinder 3 on the outside of the upright plate 2 and pass the piston rod of the hydraulic cylinder 3 through the upright plate 2. Subsequently, fasten the clamping plate 4, with the horizontal plate 5 welded to the top, to the corresponding piston rod of the hydraulic cylinder 3 with multiple bolts. The clamping plate 4 has countersunk holes to prevent the bolts from protruding. Weld the second reinforcing plates 13 on both sides of the horizontal plate 5 to ensure structural strength. Pass the screw 6 through the threaded hole of the horizontal plate 5, and then install the pressure plate 7 coaxially on the bottom of the screw 6 with bolts. Then, select whether to install the boss 8 according to the number of I-beams to be cut. When there is only one I-beam, such as Figure 4 As shown, neither of the two side plates 4 has a boss 8 installed; when there are two I-beams, as Figure 5 As shown, the flange of one I-beam is supported on the flange of another I-beam. The bottom of the clamping plate 4 on the side of the higher I-beam is inserted laterally into the boss 8 through the slot 9. The other side does not need to be installed. When clamping, the two clamping plates 4 are brought closer together by the hydraulic cylinder 3 and clamped on both sides of the two I-beams, while the boss 8 is supported on the bottom of the outer end of the higher I-beam. Rotating the two screws 6 causes the pressure plates 7 at the bottom of the two screws 6 to press down on the two I-beams respectively, completing the clamping of the two I-beams. When there are three I-beams, as shown... Figure 6 As shown, the flanges of the two outer I-beams are supported on the flange of the middle I-beam. The slots 9 at the bottom of the clamping plates 4 on both sides are into which bosses 8 are inserted. During clamping, the two clamping plates 4 are brought closer together by the hydraulic cylinder 3 and clamped to the outer sides of the two outer I-beams. The bosses 8 are supported at the bottom of the outer ends of the two I-beams. Rotating the two screws 6 causes the pressure plates 7 at the bottom of the two screws 6 to press against the two outer I-beams, thus completing the clamping of the three I-beams. It should be noted that the thickness of the bosses 8 is no greater than the thickness of the I-beam flanges. This utility model has a reasonable structure. Each clamping plate 4 has a horizontal plate 5 at its top, a screw 6 on the horizontal plate 5, and a pressure plate 7 at the bottom of the screw 6. The bottom of the inner side of the clamping plate 4 has a slot 9, which can be used to install a boss 8 laterally. When two or three I-beams are cut at the same time, the boss 8 can be installed on the corresponding clamping plate 4 to support the bottom of the stacked I-beam. The clamping plate 4 is used to clamp the side, and the screw 6 and pressure plate 7 are used to clamp the top of the I-beam. This allows for the clamping of multiple I-beams and ensures their stability, thereby improving the overall cutting efficiency.
