Description

Technical Field

[0001] The utility model relates to the technical field of steel plate connection, in particular to a positioning mechanism of an I-beam assembling machine. Background Technique

[0002] The I-beam is also called an I-shaped steel beam, which is a long steel bar with an I-shaped cross-section. It is widely used in the construction of buildings, bridges, tunnels, highways, etc. For the convenience of transportation, the length of the I-beam is generally not more than 12m. In practical applications, such as in the construction of large-span bridges, I-beams with longer lengths are often required for splicing, which requires multiple I-beams to be assembled. The assembling machine is one of the equipment for steel structure production, responsible for assembling steel structures, facilitating welding, and increasing work efficiency.

[0003] Currently, when carrying out I-beam assembling and processing, it is necessary to position and splice the I-beams. For example, the assembling and positioning structure of the I-beam disclosed in Chinese Patent Publication No. "CN214117233U" includes: a base, which has a connection area thereon; two cushion blocks, arranged on the base and located at both ends of the connection area in the length direction respectively; two I-beams, extending along the length direction of the connection area and arranged on the two cushion blocks respectively, and the projections of the ends of the two I-beams on the base are spaced apart from each other within the connection area; a plurality of limit blocks, arranged on the base along the length direction of the connection area to limit the two I-beams on one side of the two I-beams; and a first splicing plate, arranged in the connection area and connected to the ends of the two I-beams respectively at both ends.

[0004] The current positioning mechanism requires a whole I-beam to be placed in the mold for positioning. This positioning method needs to be used one by one according to the size, which not only has poor general performance and high cost, but also requires the use of the whole I-beam, affecting other processing operations on the I-beam. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art, such as poor general performance, high cost, and the need to use the whole I-beam, which affects other processing operations on the I-beam, and to propose a positioning mechanism of an I-beam assembling machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Design a positioning mechanism for an I-beam assembling machine, which includes an installation frame and an I-beam body. On both sides of the inner wall of the installation frame, there are rotatably connected two-way screws. A clamping mechanism is arranged between the two-way screw and the installation frame. On both sides of the surface of the two-way screw, there are movably connected moving plates. At the bottom of the moving plate, there is an L-shaped plate fixed. Inside the L-shaped plate, there is a strip-shaped plate fixed. A clamping mechanism is arranged on the surface of the strip-shaped plate.

[0008] Further, the clamping mechanism includes a positioning gear fixed on the surface of the two-way screw. On the surface of the installation frame, there is a fixed plate fixed. Inside the fixed plate, there is a movable column slidably connected. At the top of the movable column, there is a clamping tooth fixed. On the surface of the movable column, there is a spring sleeved and the spring abuts and is clamped with the clamping tooth and the fixed plate respectively.

[0009] Further, at the top of the movable column, there is a round plate fixed. At the edge of the round plate, there is a chamfer structure.

[0010] Further, at the top of the L-shaped plate, there is a fixed strip fixed. The fixed strip is slidably connected with the bottom of the installation frame.

[0011] Further, the clamping mechanism includes a clamping plate slidably connected inside the L-shaped plate. At the bottom of the clamping plate, there is a threaded column rotatably connected. On the surface of the strip-shaped plate, there is a threaded sleeve communicated. The threaded column is threadedly connected with the threaded sleeve. At the bottom of the threaded column, there is a knob fixed.

[0012] Further, on the surface of the L-shaped plate, there is a through groove opened. Inside the through groove, there is a guide post fixed. The guide post is slidably connected with the clamping plate.

[0013] For the positioning mechanism of the I-beam assembling machine proposed by the present utility model, the beneficial effects are as follows: Through the two-way screw, the present utility model can drive two L-shaped plates to clamp on both sides of the I-beam. The strip-shaped plate at the bottom cooperates with the clamping plate to clamp the I-beam, thereby realizing the positioning of I-beams with different sizes, greatly improving the versatility of the positioning mechanism, reducing the use cost, and when positioning, only need to fix the mechanism on one side of the I-beam, greatly reducing the shielding area and facilitating other processing operations.

[0020] Referring to Figures 1-4 , a positioning mechanism for an I-beam assembly machine includes an installation frame 1 and an I-beam body 2. Both sides of the inner wall of the installation frame 1 are rotatably connected with a bidirectional screw 3. A clamping mechanism 4 is arranged between the bidirectional screw 3 and the installation frame 1. Both sides of the surface of the bidirectional screw 3 are threadedly connected with a movable plate 5. The bottom of the movable plate 5 is fixed with an L-shaped plate 6. The inner side of the L-shaped plate 6 is fixed with a strip-shaped plate 7. A clamping mechanism 8 is arranged on the surface of the strip-shaped plate 7; through the bidirectional screw 3, the positioning mechanism can drive two L-shaped plates 6 to clamp on both sides of the I-beam, and the strip-shaped plate 7 at the bottom cooperates with the clamping plate 81 to clamp the I-beam, thereby realizing the positioning of I-beams with different sizes, greatly improving the versatility of the positioning mechanism, reducing the use cost, and only needing to fix the mechanism on one side of the I-beam during positioning, greatly reducing the shielding area and facilitating other processing operations.

[0021] In this embodiment, the clamping mechanism 4 includes a positioning gear 41. The surface of the positioning gear 41 is provided with a plurality of positioning teeth. The positioning gear 41 is fixed on the surface of the bidirectional screw 3. The surface of the installation frame 1 is fixed with a fixed plate 42. The inner side of the fixed plate 42 is slidably connected with a movable column 43. The top of the movable column 43 is fixed with a tooth 44. The pitch of the teeth of the tooth 44 corresponds to the teeth of the positioning gear 41. A spring 45 is sleeved on the surface of the movable column 43, and the spring 45 abuts and is clamped with the tooth 44 and the fixed plate 42 respectively. The bidirectional screw 3 can be positioned at any angle through the cooperation of the tooth 44 and the positioning gear 41.

[0022] Furthermore, a circular plate 9 is fixed on the top of the movable column 43, and the edge of the circular plate 9 is provided with a chamfered structure. The circular plate 9 can fit the fingers to facilitate pulling the movable column 43, and the circular plate 9 can also play a role of limiting.

[0023] Furthermore, a fixing strip 10 is fixed to the top of the L-shaped plate 6, and the fixing strip 10 is slidably connected to the bottom of the mounting frame 1. One side of the fixing strip 10 is connected to the movable plate 5. A groove fitting with the fixing strip 10 is provided at the bottom of the mounting frame 1, and the L-shaped plate 6 can be guided by the fixing strip 10.

[0024] In addition, the clamping mechanism 8 includes a clamping plate 81 with the same length as the L-shaped plate 6, and the clamping plate 81 is slidably connected to the inner side of the L-shaped plate 6. The bottom of the clamping plate 81 is rotatably connected to a threaded column 82. The surface of the strip plate 7 is connected to a threaded sleeve 83. The threaded column 82 is threadedly connected to the threaded sleeve 83. A knob 84 is fixed to the bottom of the threaded column 82.

[0025] It should be noted that a through groove 11 is provided on the surface of the L-shaped plate 6, a guide column 12 is fixed on the inner side of the through groove 11, a protrusion is provided on the outer side of the clamping plate 81 and the protrusion is slidably connected to the through groove 11, and the guide column 12 is slidably connected to the clamping plate 81. The guide column 12 on the inner side of the through groove 11 can guide the clamping plate 81.

[0026] Working method: When splicing I-beams, the staff only needs to place the two I-beams between the two L-shaped plates 6 respectively, and then pull the circular plate 9 and the movable column 43 by hand. The movable column 43 will drive the locking tooth 44 to disengage the positioning gear 41. Then the staff can rotate the bidirectional screw 3, and the bidirectional screw 3 can drive the two L-shaped plates 6 to move toward each other. The L-shaped plate 6 will clamp the transverse plate of the I-beam. After clamping, the staff can loosen the movable column 43, and the movable column 43 rebounds and clamps under the action of the spring 45. Then, the threaded column 82 is tightened by hand. The threaded column 82 drives the clamping plate 81 to press against the surface of the I-beam to fix the I-beam. The two I-beams can be positioned as a whole through this mechanism, which is convenient for other processing. During processing, the entire I-beam needs to be placed on the assembly machine for processing operations.
