Description

Technical Field

[0001] The utility model relates to the field of processing mechanisms, and particularly relates to a processing mechanism for the production of steel structure steel beams. Background Art

[0002] Steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to corrosion. Generally, steel structures need to be derusted, galvanized or painted, and need to be maintained regularly.

[0003] In the prior art, after the production of the H-shaped steel beam used in the steel structure is completed, it is necessary to drill holes on the inner bottom surface of the concave groove of the H-shaped steel beam to facilitate the connection of the H-shaped steel beam with other fasteners or other components. However, when drilling holes in some large H-shaped steel beams, due to the large size and heavy weight of the H-shaped steel beam, it is difficult to drill holes in the H-shaped steel beam through a fixed drilling device. Therefore, when drilling holes in the H-shaped steel beam, the staff often carry a portable small drilling machine to the position where the hole needs to be drilled on the H-shaped steel beam and realize the drilling operation by operating the drilling machine. However, in this way, when drilling holes in the H-shaped steel beam, due to the large number of drilling positions, it is necessary for the staff to continuously carry and change the position of the drilling machine according to the opening position to complete the drilling operation, which makes it time-consuming and laborious to drill holes in the H-shaped steel beam. Moreover, after the drilling machine is carried to the drilling position, it is necessary to adjust the position of the drilling machine so that the drill bit is aligned with the opening position, which is rather troublesome to operate, thus reducing the working efficiency and drilling accuracy of drilling holes in the H-shaped steel beam.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figure 1 - Figure 4As shown in the figure, a processing mechanism for the production of steel structure steel beams includes an H-shaped steel beam 1 and a concave groove 2 formed on the top and bottom surfaces of the H-shaped steel beam 1. A moving positioning mechanism 3 is provided inside the concave groove 2 on the top surface of the H-shaped steel beam 1.

A drilling processing mechanism 4 is also provided on the top surface of the moving table 5. The drilling processing mechanism 4 includes a top plate 17, a fixing plate 19, a lead screw 21, a servo motor 23, an L-shaped plate 24, a cylinder 28, a concave seat 29, a driving motor 31 and a drill bit 32.

[0021] As Figure 3 shown, two sets of symmetric first sliding openings 6 are formed on the top surface of the moving table 5, and a set of left and right symmetric mounting seats 7 are fixedly installed on the bottom surface of the moving table 5. The first electric push rods 8 are fixedly installed on the outer side walls of the mounting seats 7, and the output ends of the first electric push rods 8 are fixedly installed with the adjusting plate 9.

[0022] As Figure 3As shown in the figure, a second electric push rod 11 is fixedly installed on the inner side wall of the adjusting plate 9, and a positioning plate 12 is fixedly installed on the output end of the second electric push rod 11. A set of symmetrical bearing seats 13 are fixedly installed on the outer side wall and the bottom surface of the adjusting plate 9 respectively, and a rotating bearing 14 is fixedly installed inside the bearing seat 13. A rotating shaft 16 is fixedly installed on one end wall of the roller 15, and the rotating shaft 16 is fixedly installed through the rotating bearing 14. During the movement of the moving positioning mechanism 3 in the concave groove 2, the symmetrical rollers 15 on the outer side wall and the inner side wall of the adjusting plate 9 will closely roll on the inner side wall and the bottom surface of the concave groove 2, and the rotating shaft 16 will rotate in the rotating bearing 14 installed in the bearing seat 13, so that the moving table 5 can move on the top surface of the H-shaped steel beam 1, so as to drive the drilling mechanism 4 to quickly move to the opening position. There is no need for workers to carry and move it, which is time-saving and labor-saving. At the same time, after moving to the designated position, the second electric push rod 11 can be activated to drive the output end to push the positioning plate 12, so that the positioning plate 12 abuts against the inner side wall of the groove of the concave groove 2. In this way, the moving table 5 can be prevented from moving through the rollers 15 again, and it is ensured that the drilling mechanism 4 will not be displaced when drilling the H-shaped steel beam 1;

[0023] As Figure 4 shown in the figure, the top plate 17 is fixedly installed at the front end of the top surface of the moving table 5, and a horizontal limiting port 18 is opened on the front end wall of the top plate 17. A set of left and right symmetrical fixing plates 19 are fixedly installed on the rear end wall of the top plate 17, and a rotating hole 20 is opened on the side wall of the fixing plate 19. Through the limiting port 18, the connecting plate 25 can pass through the top plate 17 to be connected with the lead screw 21, and play a role in limiting the movement of the connecting plate 25, and the rotating hole 20 opened on the fixing plate 19 enables the rotating rod 22 to rotate in the rotating hole 20;

[0024] As Figure 4As shown in the figure, rotating rods 22 are fixedly installed at the left and right ends of the lead screw 21, and the rotating rods 22 are movably installed in the rotating holes 20. The servo motor 23 is fixedly installed on the outer wall of the right fixing plate 19, and the output end of the servo motor 23 is fixedly installed together with the rotating rod 22 at the right end. The L-shaped plate 24 is in an inverted state, and a connecting plate 25 is fixedly installed on the rear end wall of the vertical part of the L-shaped plate 24. The connecting plate 25 passes through the limiting port 18, and a threaded hole 26 is formed in the side wall of the connecting plate 25 and is threadedly connected to the lead screw 21 through the threaded hole 26. A group of vertically symmetric second sliding ports 27 are also formed in the front end wall of the vertical part of the L-shaped plate 24. After the drilling mechanism 4 to be processed moves to the opening position through the moving and positioning mechanism 3, according to the number of transverse holes to be opened, the servo motor 23 is started. The servo motor 23 drives the output end to drive the rotating rod 22 to rotate in the rotating hole 20. The rotating rod 22 drives the lead screw 21 to rotate, so that the connecting plate 25 drives the L-shaped plate 24 to move horizontally in the limiting port 18 through the threaded hole 26 along the lead screw 21. In this way, the drill bit 32 can be quickly moved directly above the hole position to be opened;

[0025] As Figure 4 shown in the figure, the cylinder 28 is fixedly installed on the top surface of the transverse part of the L-shaped plate 24, and a concave seat 29 is fixedly installed on the output end of the cylinder 28. A group of symmetric second sliders 30 are fixedly installed at the top of the rear end wall of the concave seat 29, and the second sliders 30 are movably installed in the second sliding ports 27. The driving motor 31 is fixedly installed inside the concave seat 29, and the drill bit 32 is fixedly installed on the output end of the driving motor 31. After the drill bit 32 moves directly above the card hole position, the cylinder 28 is started to drive the output end to push the concave seat 29. The concave seat 29 moves downward along the second sliding port 27 through the second slider 30. At the same time, the driving motor 31 is started, and the driving motor 31 drives the output end to drive the drill bit 32 to rotate. After the drill bit 32 moves downward and contacts the opening position in the concave groove 2, drilling operation will be carried out on the H-shaped steel beam 1.

[0026] It should be noted that the utility model is a processing mechanism for producing steel beams for steel structures. When drilling a large H-shaped steel beam 1 for a steel structure, the movable platform 5 is placed above the H-shaped steel beam 1. At this time, the roller 15 located on the inner side wall of the adjustment plate 9 in a horizontal state will contact the bottom surface of the groove of the concave groove 2. Then, the distance between the adjustment plates 9 is adjusted according to the width of the H-shaped steel beam 1 and the groove width of the concave groove 2. The first electric push rod 8 installed on the outer side walls of the mounting seats 7 on both sides of the bottom surface of the movable platform 5 is turned on. The first electric push rod 8 drives the adjustment plate 9 to move outward with the pneumatic output end. During the movement, the first slider 10 installed on the top surface of the adjustment plate 9 will slide in the first sliding opening 6 opened on the top surface of the movable platform 5 until the outer side wall of the adjustment plate 9 is vertical. The roller 15 in the state can be in close contact with the inner side wall of the concave groove 2. Then, according to the hole opening position required for drilling on the inner bottom surface of the concave groove 2, the drill bit 32 on the drilling processing mechanism 4 is moved to the same parallel position as the hole opening position. The movable platform 5 can be manually pushed to move the drilling processing mechanism 4. When moving, the rollers 15 on the inner and outer walls of the adjusting plate 9 will roll in close contact with the inner bottom surface and outer wall of the concave groove 2. When rolling, the rollers 15 will drive the rotating shaft 16 to rotate in the rotating bearing 14 in the corresponding bearing seat 13 installed on the adjusting plate 9, so that the drilling processing mechanism 4 can move to the hole opening position along the H-shaped steel beam 1, and after moving to the hole opening position, the second electric push rod 11 installed on the inner wall of the adjusting plate 9 is turned on, and the second electric push rod 11 will drive The output end of the motor pushes the positioning plate 12 so that the positioning plate 12 is pressed against the two sides of the inner wall of the concave groove 2 to play a positioning role and prevent the drilling mechanism 4 from being displaced when drilling the H-shaped steel beam 1. Subsequently, the servo motor 23 installed on the outer wall of the right fixing plate 19 is turned on. The servo motor 23 will drive the output end to drive the rotating rod 22 to rotate in the rotating hole 20 opened on the side wall of the fixing plate 19, and the rotating rod 22 will drive the screw rod 21 to rotate between the fixing plates 19, and make the connecting plate 25 pass through the screw hole 26 opened on the side wall along the screw rod 21 to realize horizontal movement in the horizontal limit opening 18 opened on the front end wall of the top plate 17 installed on the top surface of the moving platform 5, and the connecting plate 25 will drive the L-shaped plate 24 to synchronously move horizontally on the front end wall of the top plate 17 The L-shaped plate 24 is stopped after the drill bit 32 moves to the position of the opening pre-marked on the bottom surface of the concave groove 2, and then the cylinder 28 installed on the top surface of the lateral part of the L-shaped plate 24 is turned on. The cylinder 28 drives the output end to push the concave seat 29 downward. The second slider 30 installed on the top of the rear end wall of the concave seat 29 slides in the second sliding opening 27 provided on the front end wall of the lateral part of the L-shaped plate 24, so that the drill bit 32 moves downward and gradually approaches the screw hole at the opening position. At the same time, in the process of the drill bit 32 moving downward, the drive motor 31 installed in the concave seat 29 is turned on. The drive motor 31 drives the output end to drive the drill bit 32 to rotate. After the drill bit 32 rotates downward, it will complete the drilling operation at the opening position.After the drilling is completed, move the drill bit 32 upward, then move the drill bit 32 horizontally to the next drilling position for drilling. Finally, after the drilling is completed at this position, move the drilling mechanism 4 to another drilling position for drilling by moving the positioning mechanism 3. Thus, when drilling the large H-shaped steel beam 1, the purpose of facilitating rapid and accurate drilling can be achieved. Moreover, when drilling the H-shaped steel beam 1, there is no need for manual repeated lifting of the drilling equipment according to the drilling positions, and the operation is simple, convenient, fast, time-saving and labor-saving. Furthermore, the working efficiency and drilling accuracy of the drilling of the H-shaped steel beam 1 are improved.
