Description

Technical Field

[0001] This utility model relates to the field of rectangular tube processing technology, and specifically to a drilling device for rectangular tube processing. Background Technology

[0002] Rectangular tubes are hollow, square-section, lightweight, thin-walled steel pipes, also known as cold-formed steel profiles. It is a square-section steel profile made from Q235 hot-rolled or cold-rolled strip steel or coil as the base material, which is cold-bent and then high-frequency welded. Except for the increased wall thickness, the corner dimensions and edge straightness of hot-rolled extra-thick-walled square tubes reach or even exceed the level of resistance-welded cold-formed square tubes. Rectangular tubes, being long steel strips, are lighter in weight while maintaining the same bending and torsional strength, and are therefore widely used in manufacturing mechanical parts and engineering structures. In the processing of rectangular tubes, drilling equipment is required to drill holes in their surface. Some existing drilling equipment for rectangular tube processing can clamp and limit the two sides of the rectangular tube to prevent displacement during continuous drilling and thus affect drilling accuracy. However, in actual use, after continuous drilling, the rectangular tube gradually moves away from the worktable. Due to the lack of a downward limiting structure, the rectangular tube may tilt, requiring the operator to hold it to maintain its flatness, increasing the operator's workload and affecting the drilling quality. Utility Model Content

[0003] In view of this, the present invention provides a drilling device for processing rectangular tubes, which can press down and limit the rectangular tubes to prevent them from warping, reduce the workload of operators, and ensure the drilling quality of the rectangular tubes.

[0004] To solve the above-mentioned technical problems, this utility model provides a drilling device for processing rectangular tubes, including a worktable, on which a rectangular tube is disposed and a drilling machine is disposed. The worktable is provided with a pressing mechanism for preventing the rectangular tube from tilting up. The pressing mechanism includes a pressing plate for pressing down on the rectangular tube, a transmission component for driving the pressing plate to move, and a square frame for the drilling machine to pass through. A sliding member is connected to the square frame to facilitate the stable movement of the pressing plate. The pressing mechanism can prevent the rectangular tube from tilting up by limiting the pressing.

[0005] A fixed frame is provided on the workbench. The transmission assembly includes a bracket mounted on the fixed frame, a connecting box mounted on the bracket, a rotary motor mounted on the connecting box, a rotating rod connected to the output end of the rotary motor, a gear mounted on the rotating rod, and a rack plate slidably mounted on the bracket and connected to the lower pressure plate. The gear and rack plate mesh with each other. The rotary motor can be started, causing the rotating rod to drive the gear to rotate. Under the meshing action, the rack plate will drive the lower pressure plate to move downward until it contacts the upper surface of the rectangular tube.

[0006] The sliding component includes two corresponding sliding grooves on the fixed frame. Each sliding groove is equipped with a support rod, and a connecting plate connected to the square frame is slidably mounted on the support rod. During the movement of the lower pressure plate, the connecting plate slides on the support rod, which can ensure the stability of the movement of the lower pressure plate and ensure that the lower pressure plate is in full contact with the upper surface of the rectangular tube.

[0007] The fixed frame has two corresponding cylinders. The telescopic ends of the cylinders are connected to limit plates, which are used to adjust and limit the two sides of the rectangular tube. The operator can start the cylinders to extend the limit plates and limit the two sides of the rectangular tube.

[0008] A second cylinder is installed on the workbench. A push plate is connected to the telescopic end of the second cylinder to push the rectangular tube to move. The operator can start the second cylinder to make the push plate push the rectangular tube to move back and forth between the limit plate and the lower pressure plate, and then perform drilling operations again.

[0009] The workbench has discharge holes. The drill bit and square frame of the drilling machine correspond one-to-one with the discharge holes. The operator can start the drilling machine, pass through the square frame to drill holes in the rectangular tube, and the material drilled from the rectangular tube can be discharged through the discharge holes.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. When using this utility model, the rectangular tube can be pressed down and limited to prevent it from tilting up, thus reducing the workload of the operator and ensuring the drilling quality of the rectangular tube.

[0012] 2. When this utility model is in use, the connecting plate slides on the support rod during the movement of the lower pressure plate, which can ensure the stability of the movement of the lower pressure plate and ensure that the lower pressure plate is in full contact with the upper surface of the rectangular tube.

[0013] 3. When using this utility model, the operator can start cylinder one to extend the limiting plate and adjust and limit the two sides of the rectangular tube.

[0014] 4. When using this utility model, the drill bit, square frame and discharge hole of the drilling machine correspond one-to-one. The operator can start the drilling machine, pass through the square frame to drill the rectangular tube, and the material drilled from the rectangular tube can be discharged through the discharge hole.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] According to one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown: This embodiment provides a drilling device for processing rectangular tubes, including a worktable 10, on which a rectangular tube 30 is disposed, and a drilling machine 60 is also disposed. The worktable 10 is provided with a pressing mechanism 20 for preventing the rectangular tube 30 from tilting up. The pressing mechanism 20 includes a pressing plate 22 for pressing down and contacting the rectangular tube 30. The pressing plate 22 is provided with a transmission component 21 for driving the pressing plate 22 to move. The pressing plate 22 is provided with a square frame 23 for the drilling machine 60 to pass through. A sliding member 24 is connected to the square frame 23 to facilitate the stable movement of the pressing plate 22. The pressing mechanism 20 can prevent the rectangular tube 30 from tilting up by pressing down and limiting it.

[0025] Furthermore, such as Figure 3 and Figure 4As shown, a fixed frame 241 is provided on the workbench 10. The transmission assembly 21 includes a bracket 211 provided on the fixed frame 241, a connecting box 212 provided on the bracket 211, a rotary motor 213 provided on the connecting box 212, a rotating rod 214 connected to the output end of the rotary motor 213, a gear 215 provided on the rotating rod 214, and a rack plate 216 slidably provided on the bracket 211 and connected to the lower pressure plate 22. The gear 215 meshes with the rack plate 216, which can start the rotary motor 213, causing the rotating rod 214 to drive the gear 215 to rotate. Under the meshing action, the rack plate 216 will drive the lower pressure plate 22 to move downward until it contacts the upper surface of the rectangular tube 30.

[0026] Furthermore, such as Figure 5 As shown, the sliding member 24 includes two sliding grooves 242 corresponding to those opened on the fixed frame 241. Each sliding groove 242 is provided with a support rod 243. A connecting plate 244 connected to the square frame 23 is slidably disposed on the support rod 243. During the movement of the lower pressure plate 22, the connecting plate 244 slides on the support rod 243, which can ensure the stability of the movement of the lower pressure plate 22 and ensure that the lower pressure plate 22 is in full contact with the upper surface of the rectangular tube 30.

[0027] Furthermore, two corresponding cylinders 41 are provided on the fixed frame 241. The telescopic ends of the cylinders 41 are connected to limit plates 42 for adjusting and limiting the two sides of the rectangular tube 30. The operator can start the cylinders 41 to extend the limit plates 42 and limit the two sides of the rectangular tube 30.

[0028] According to another embodiment of the present invention, such as Figure 1 and Figure 5 As shown, a second cylinder 51 is provided on the workbench 10. The telescopic end of the second cylinder 51 is connected to a push plate 52, which is used to push the rectangular tube 30 to move. The operator can start the second cylinder 51, so that the push plate 52 pushes the rectangular tube 30 to move back and forth between the limit plate 42 and the lower pressure plate 22, and then perform drilling operations again.

[0029] Furthermore, the workbench 10 is provided with a discharge hole 70. The drill bit of the drilling machine 60 and the square frame 23 correspond one-to-one with the discharge hole 70. The operator can start the drilling machine 60 and drill through the square frame 23 to drill the rectangular tube 30. The material drilled from the rectangular tube 30 can be discharged through the discharge hole 70.

[0030] The method of using this utility model is as follows: During the drilling operation of the rectangular tube 30, the operator can place the rectangular tube 30 to be drilled on the workbench 10 until one end of the rectangular tube 30 contacts the push plate 52. Then, the operator can activate the cylinder 41 to extend the limiting plate 42 to limit the two sides of the rectangular tube 30. After that, the operator can activate the rotary motor 213 to make the rotating rod 214 drive the gear 215 to rotate. Under the meshing action, the rack plate 216 will drive the lower pressure plate 22 to move downward until it contacts the upper surface of the rectangular tube 30. During the movement, the connecting plate 244 slides on the support rod 243. This design ensures stable movement of the lower pressure plate 22 and guarantees full contact between the lower pressure plate 22 and the upper surface of the rectangular tube 30. The operator can then start the drilling machine 60, which passes through the square frame 23 to drill through the rectangular tube 30. The drilled material can be discharged through the discharge hole 70. Afterward, the operator can activate cylinder 51, causing the push plate 52 to push the rectangular tube 30 back and forth between the limiting plate 42 and the lower pressure plate 22, and perform drilling again. This invention can limit the downward movement of the rectangular tube 30, preventing it from tilting, reducing the operator's workload, and ensuring the drilling quality of the rectangular tube 30.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
