Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for the production of steel structural components. Background Technology

[0002] Utility model publication CN222740358U relates to the field of steel structure component processing technology, and more particularly to a drilling device for steel structure component production. The device includes a vertical adjustment mechanism with two sets of electromagnets mounted at its bottom. A horizontal adjustment mechanism is movably connected to the right side of the vertical adjustment mechanism, and a longitudinal adjustment mechanism is movably mounted on the upper side of the horizontal adjustment mechanism. A drilling mechanism is mounted on the upper side of the longitudinal adjustment mechanism. This utility model uses electromagnets to fix the entire device to the steel structure, facilitating drilling of the steel structure components and greatly reducing the labor intensity of operators. Furthermore, through the coordinated operation of the various adjustment mechanisms, the drilling position can be quickly adjusted, improving operational convenience and significantly increasing drilling efficiency and accuracy.

[0003] After searching, it was found that the existing technology uses an electromagnet to connect and fix the steel structure to the surface. Since the required drilling position for the steel structure is usually at the end of the web, while the electromagnet in the existing technology is connected to the side of the flange of the steel structure, the connection surface area is small and the fixing effect is poor. In addition, there is a positioning deviation between the drilling device and the steel structure. Although the drilling device itself can move horizontally, the tilt deviation between the installation and the steel structure can easily lead to the drilling position deviation. Therefore, a drilling device for steel structure production is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for the production of steel structural components, 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 drilling device for producing steel structural components, comprising a support plate, on which a bidirectional screw is rotatably connected, and a first moving block and a second moving block are threadedly connected to the bidirectional screw. The first and second moving blocks are symmetrically arranged between the two side flanges of the steel structural component. Clamping plates are provided at the bottom ends of both the first and second moving blocks. A first screw is rotatably connected to the support plate, and the first screw is parallel to the bidirectional screw. A third moving block is threadedly connected to the first screw. A connecting bracket is provided at the top end of the third moving block. A mounting bracket is vertically slidably connected within the connecting bracket. A motor is mounted on the mounting bracket, and a drill chuck is mounted on the output shaft of the motor. A drill bit is installed inside the drill chuck. A positioning bracket is provided at the bottom end of the third moving block. The positioning bracket is U-shaped, with parallel branches on both sides arranged above and below the web of the steel structural component, and a vertical branch on one side arranged on the outside of the web of the steel structural component. The drill bit can penetrate the parallel branches on both sides of the positioning bracket.

[0006] Preferably, the first movable block has a positive thread hole that matches the positive thread section of the bidirectional screw, and the second movable block has a negative thread hole that matches the negative thread section of the bidirectional screw.

[0007] Preferably, the pallet has a first sliding groove, and both the first moving block and the second moving block are slidably connected within the first sliding groove.

[0008] Preferably, rubber pads are provided on both sides of the two clamping plates that are far apart from each other.

[0009] Preferably, the pallet has a second groove, and the third moving block is slidably connected in the second groove.

[0010] Preferably, the connecting bracket is provided with a vertically arranged guide rod, and a slider is slidably connected to the guide rod, the slider being connected to the mounting bracket.

[0011] Preferably, a second screw is rotatably connected to the vertical branch of the positioning bracket, and a fourth moving block is threadedly connected to the second screw. The fourth moving block is vertically slidably connected inside the positioning bracket, and a support plate is provided on one side of the fourth moving block. The support plate is arranged below the bottom branch of the positioning bracket and the web of the steel structure, and the drill bit can penetrate through the support plate.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the cooperation between the bidirectional screw, the first moving block, the second moving block, and the clamping plate enables the bidirectional screw to rotate, thereby achieving relative movement between the first and second moving blocks. This causes the two clamping plates to move away from the two side flanges of the steel structure, thus achieving the fixing effect of the support plate and the drilling device. Furthermore, the first screw drives the third moving block to move, and the drill bit moves horizontally with the web of the steel structure, which is always perpendicular to it, thereby improving the accuracy of the drilling position and reducing deviation.

[0014] In this invention, the arrangement of two clamping plates at the flange of the steel structure and the arrangement of the positioning bracket at the web position make the drilling device more stable on the steel structure, while ensuring stability and safety during the drilling process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A drilling device for producing steel structural components includes a support plate 1, a bidirectional screw 2 rotatably connected to the support plate 1, a first moving block 3 and a second moving block 4 threadedly connected to the bidirectional screw 2, the first moving block 3 and the second moving block 4 being symmetrically arranged between the two side flanges of the steel structural component, and a clamping plate 5 being provided at the bottom end of each of the first moving block 3 and the second moving block 4; a first screw 6 rotatably connected to the support plate 1, the first screw 6 being parallel to the bidirectional screw 2, and a third moving block 7 threadedly connected to the first screw 6; the third moving block 7... A connecting bracket 8 is provided at the top, and a mounting bracket 9 is vertically slidably connected inside the connecting bracket 8. A motor 10 is provided on the mounting bracket 9, and a drill chuck 11 is provided on the output shaft of the motor 10. A drill bit 12 is provided inside the drill chuck 11. A positioning bracket 13 is provided at the bottom of the third moving block 7. The positioning bracket 13 is U-shaped, with two parallel branches arranged above and below the web of the steel structure member, respectively, and one vertical branch arranged on the outside of the web of the steel structure member. The drill bit 12 can penetrate the two parallel branches of the positioning bracket 13.

[0022] The drilling device is placed on both sides of the flange plate of the steel structure. It is pushed inwards along the longitudinal direction of the steel structure, causing the two parallel branches of the positioning bracket 13 to be positioned at the upper and lower ends of the web plate. The handwheel at the bidirectional screw 2 is rotated, causing the first moving block 3 and the second moving block 4 to move away from each other, so that the two clamping plates 5 are in contact with the inner sides of the two side flange plates. The handwheel at the first screw 6 is rotated, causing the third moving block 7 to drive the connecting bracket 8 and the positioning bracket 13 to move synchronously, aligning the drill bit 12 with the desired drilling position and driving the drilling... The motor 10 causes the drill chuck 11 to rotate, driving the drill bit 12. The handle at the mounting bracket 9 is used to move the mounting bracket 9 downward, thereby moving the motor 10, drill chuck 11, and drill bit 12 downward to perform drilling operations on the web of the steel structure. Compared with the prior art, the arrangement of the two clamping plates 5 at the flange of the steel structure and the arrangement of the positioning bracket 13 at the web position make the drilling device more stable on the steel structure, while ensuring the stability and safety of the drilling process, effectively reducing deviation and improving the accuracy of the drilling position.

[0023] Specifically, in this embodiment, the first moving block 3 is provided with a positive thread hole that matches the positive thread section of the bidirectional screw 2, and the second moving block 4 is provided with a negative thread hole that matches the negative thread section of the bidirectional screw 2, thereby achieving the effect of synchronous relative movement of the first moving block 3 and the second moving block 4.

[0024] Specifically, in this embodiment, a first sliding groove 14 is provided on the pallet 1, and the first moving block 3 and the second moving block 4 are both slidably connected in the first sliding groove 14, which ensures the horizontal stability of the relative movement of the first moving block 3 and the second moving block 4.

[0025] Specifically, in this embodiment, rubber pads 15 are provided on both sides of the two clamping plates 5 that are far apart from each other, which improves the friction efficiency between the two clamping plates 5 and the flange of the steel structure and ensures the stability of the installation and fixing.

[0026] Specifically, in this embodiment, a second sliding groove 16 is provided on the pallet 1, and the third moving block 7 is slidably connected in the second sliding groove 16, which improves the horizontal movement stability of the third moving block 7.

[0027] Specifically, in this embodiment, a vertically arranged guide rod 17 is provided inside the connecting bracket 8, and a slider 18 is slidably connected to the guide rod 17. The slider 18 is connected to the mounting bracket 9, which improves the connection effect between the mounting bracket 9 and the connecting bracket 8, and at the same time ensures the vertical movement stability of the mounting bracket 9.

[0028] Specifically, in this embodiment, a second screw 19 is rotatably connected to the vertical branch of the positioning bracket 13, and a fourth moving block 20 is threadedly connected to the second screw 19. The fourth moving block 20 is vertically slidably connected inside the positioning bracket 13. A support plate 21 is provided on one side of the fourth moving block 20. The support plate 21 is arranged below the bottom branch of the positioning bracket 13 and the web of the steel structure. The drill bit 12 can penetrate the support plate 21. By using the knob at the second screw 19, the fourth moving block 20 drives the support plate 21 to move towards the bottom of the web of the steel structure, thereby providing support for the reaction force generated between the drill bit 12 and the web during drilling, preventing the drilling device from overturning, and further improving the stability of the drilling device.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
