Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling device for sheet metal used in the production of school basketball hoops. Background Technology

[0002] In applications such as school basketball hoops, due to the high frequency of use and high intensity, the connection stability of the basketball backboard is required to be higher. The use of threaded holes and bolts can form a tight mechanical connection, which can effectively resist the impact and vibration of the basketball backboard during use. The threaded connection method is easy to disassemble and install, which is beneficial to the later maintenance and replacement of the basketball backboard.

[0003] An existing patent (publication number: CN211889115U) discloses a drilling device for sheet metal used in the production of school basketball hoops. The device includes a processing table and a drilling machine. A fixed frame is fixedly connected to the upper surface of the processing table, and a sealing door is hinged to the front surface of the processing table. A drive plate is fixedly connected to the lower surface of the top of the fixed frame, and a connecting plate is slidably connected to the lower surface of the drive plate. The drilling machine is fixedly connected to the lower surface of the connecting plate. Vacuum pumps are fixedly connected to both sides of the lower surface of the connecting plate near the connecting plate, and cylinders are fixedly connected to both sides of the lower surface of the connecting plate near the vacuum pumps. This utility model relates to the field of sheet metal processing technology. This drilling device for sheet metal used in the production of school basketball hoops has a high degree of automation and mechanization, enabling rapid, automated, and continuous processing. During processing, the device maintains good stability with the sheet metal. Through the limiting rollers and vacuum suction cups, the sheet metal can be well fixed, thereby improving the processing quality.

[0004] The aforementioned drilling device can effectively fix the sheet metal using a limiting roller and a vacuum suction cup, thereby improving the processing quality. However, in the production process of basketball backboards, some holes in the backboard need to be threaded. Therefore, after drilling, a tapping mechanism is required. The aforementioned equipment cannot perform the tapping function, and the sheet metal needs to be transferred to a dedicated tapping machine for secondary processing. This not only increases the logistics transfer process and the risk of clamping errors, but also extends the production cycle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling device for sheet metal used in the production of school basketball hoops, which has the advantages of high production efficiency and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for sheet metal used in the production of campus basketball hoops, comprising a processing truss and two adjustable-spacing conveyor plates. The two conveyor plates are located within the processing truss. Supporting protrusions are provided on the side of the two conveyor plates that are close to each other. A set of conveyor shafts is rotatably connected to both ends of the two conveyor plates. A conveyor belt is provided on the side of the two conveyor plates that are close to each other. A pulley is fixedly connected to the outer surface of each conveyor shaft. Each set of pulleys is connected to each other through a conveyor belt that is close to each other. The inner top wall of each conveyor belt is in contact with the upper surface of its adjacent supporting protrusion.

[0007] Both of the conveyor plates are provided with positioning mechanisms for positioning the basketball backboard on their sides that are close to each other.

[0008] One side of each of the two conveyor plates is provided with a fixing mechanism for fixing the basketball backboard;

[0009] The inner bottom wall of the processing truss is equipped with two bottom first straight modules, and a bottom second straight module is slidably connected to the two bottom first straight modules. The bottom second straight modules are arranged parallel to the conveyor plate, and a tapping mechanism is arranged above the bottom second straight modules.

[0010] The inner top wall of the processing truss is equipped with two top first linear modules, and the bottom of the two first linear modules is slidably connected to a top second linear module. A drilling mechanism is provided below the top second linear module.

[0011] Furthermore, each of the positioning mechanisms includes an electric slide rail, each electric slide rail is fixedly connected to a conveyor plate adjacent to it, each electric slide rail is slidably connected to a detection block, and each detection block is equipped with a photoelectric switch.

[0012] The above solution, with the setting of two photoelectric switches, can detect both ends of the backboard. When both photoelectric switches detect the backboard, the external control system can be linked to stop the conveyor belt to ensure that the middle of the backboard is located between the fixed mechanisms.

[0013] Furthermore, the two fixing mechanisms include drive boxes, and cylinders are fixedly embedded in the inner sidewalls of the two drive boxes. Clamping blocks are fixedly connected to the output ends of the two cylinders, and the bottoms of the two clamping blocks are on the same reference plane as the upper surface of the conveyor belts adjacent to them.

[0014] The above solution uses a cylinder to drive two clamping blocks closer together, which can achieve the purpose of fixing and clamping the backboard to avoid shaking during drilling and tapping.

[0015] Furthermore, the tapping mechanism includes a bottom slider, which is slidably connected to the bottom second linear module. A bottom electric push rod is fixedly installed on the upper surface of the bottom slider, and an electric tapping machine is installed at the output end of the bottom electric push rod.

[0016] With the above solution, the bottom second linear module can drive the electric tapping machine to accurately position the tapping position along the X-axis. The bottom electric push rod controls the tapping depth by extending and retracting in the Z-axis direction. After the drilling mechanism completes the current hole processing, the tapping mechanism immediately performs tapping operation on the completed hole, forming a composite processing, which significantly improves the processing efficiency of a single station.

[0017] Furthermore, the drilling mechanism includes a top slider, which is slidably connected to the top second linear module. A top electric actuator is fixedly installed at the bottom of the top slider, and an electric drilling machine is installed at the output end of the top electric actuator.

[0018] Through the above scheme, the top second linear module, together with the top electric push rod, forms a dual-axis motion of X and Z, which enables the electric drilling machine to adjust the hole position along the length of the board and control the drilling depth through vertical feed. This mechanism and the tapping mechanism form a coordinated operation mode between the upper and lower positions, and the drilling and tapping processes are completed simultaneously during the board conveying process, reducing secondary clamping errors.

[0019] Furthermore, a bidirectional lead screw is rotatably connected between the two inner sidewalls of the processing truss, and the bottom ends of the two conveying plates are respectively threaded to the two ends of the bidirectional lead screw. A set of guide rods is provided between the two processing trusses, and each conveying plate is slidably connected to a set of guide rods. One end of the bidirectional lead screw is connected to an external power source.

[0020] With the above scheme, when the power source drives the lead screw to rotate, the two conveyor plates move in opposite directions or away from each other along the guide rod, thereby realizing the adjustment of the width of the conveying channel.

[0021] Furthermore, a motor is installed on one side of each of the two conveyor plates, and the output ends of the two motors are fixedly connected to the conveyor shafts adjacent to them.

[0022] Through the above scheme, the two motors achieve synchronous drive of the conveyor belt through an external differential speed control system. When the photoelectric switch of the positioning mechanism detects the plate arrival signal, the control system can simultaneously pause the two motors, so that the plate stops precisely in the working area of ​​the fixed mechanism.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This device for drilling basketball backboards used in the production of school basketball hoops utilizes adjustable-spacing conveyor plates within the processing truss, along with a conveyor belt, to achieve adaptive conveying of basketball backboards of different specifications. During movement, photoelectric switches in the positioning mechanism can position basketball backboards of different sizes, ensuring that the conveyor belt transports the backboard to the center of the fixing mechanism. The fixing mechanism then stably clamps the backboard, preventing processing deviation and ensuring drilling and tapping accuracy. The combination of drilling and tapping mechanisms enables simultaneous tapping after drilling, eliminating secondary transfer steps, reducing clamping errors, and improving single-piece processing efficiency. The bottom first linear module, bottom second linear module, top first linear module, and top second linear module enable automatic movement of the drilling and tapping mechanisms, facilitating automatic positioning, drilling, and tapping of multiple holes in the backboard.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a drilling device for producing basketball hoops for school use includes a processing truss 1 and two adjustable-spacing conveyor plates 2. The two conveyor plates 2 are located inside the processing truss 1. Supporting protrusions 201 are provided on the side of the two conveyor plates 2 that are close to each other. A set of conveyor shafts 3 are rotatably connected to both ends of the two conveyor plates 2. A conveyor belt 4 is provided on the side of the two conveyor plates 2 that are close to each other. A pulley 5 is fixedly connected to the outer surface of each conveyor shaft 3. Each set of pulleys 5 is connected to each other through the conveyor belts 4 that are close to each other. The inner top wall of each conveyor belt 4 is in contact with the upper surface of its adjacent supporting protrusion 201. By adjusting the spacing between the two conveyor plates 2, the purpose of conveying basketball backboards of different sizes can be achieved, realizing the continuous processing of backboards.

[0041] Please see Figure 1 , Figure 2 and Figure 3 A bidirectional lead screw 14 is rotatably connected between the two inner walls of the processing truss 1. The bottom ends of the two conveying plates 2 are threadedly connected to the two ends of the bidirectional lead screw 14. A set of guide rods 15 is provided between the two processing trusses 1. Each conveying plate 2 is slidably connected to a set of guide rods 15. One end of the bidirectional lead screw 14 is connected to an external power source. When the power source drives the lead screw to rotate, the two conveying plates 2 move towards or away from each other along the guide rods 15 to realize the adjustment of the conveying channel width. A motor 16 is installed on one side of each of the two conveying plates 2.

[0042] Please see Figure 1 , Figure 2 and Figure 4Each of the two conveyor plates 2 has a positioning mechanism 6 on its adjacent side for positioning the basketball backboard, enabling positioning of boards of different sizes. Each of the two conveyor plates 2 also has a fixing mechanism 7 on one side for fixing the basketball backboard, preventing board displacement during drilling, improving drilling accuracy, and improving the assembly accuracy of the backboard and the railing. Each positioning mechanism 6 includes an electric slide rail 601, which is fixedly connected to the conveyor plate 2 adjacent to it. Each electric slide rail 601 is slidably connected to a detection block 602, and each detection block 602 is equipped with a photoelectric switch 603. By setting two photoelectric switches 603, both ends of the backboard can be detected. When both photoelectric switches 603 detect the backboard, the external control system can be linked to stop the conveyor belt 4 to ensure that the middle of the backboard is located between the fixing mechanisms 7.

[0043] Please see Figure 1 , Figure 2 and Figure 5 The two fixing mechanisms 7 include drive boxes 701, and cylinders 702 are fixedly embedded in the inner walls of the two drive boxes 701. The output ends of the two cylinders 702 are fixedly connected to clamping blocks 703. The bottom of the two clamping blocks 703 is on the same reference plane as the upper surface of the conveyor belt 4 that is close to it. By driving the two clamping blocks 703 to move closer to each other through the cylinders 702, the purpose of fixing and clamping the board can be achieved to avoid shaking during drilling and tapping. Two bottom first linear modules 8 are installed on the inner bottom wall of the processing truss 1. Bottom second linear modules 9 are slidably connected to the two bottom first linear modules 8. Bottom second linear modules 9 are arranged parallel to the conveyor plate 2. A tapping mechanism 10 is arranged above the bottom second linear modules 9. The output ends of the two motors 16 are fixedly connected to the conveyor shaft 3 that is close to them. The two motors 16 realize synchronous driving of the conveyor belt 4 through an external differential speed control system. When the photoelectric switch 603 of the positioning mechanism 6 detects the board arrival signal, the control system can synchronously stop the two motors 16, so that the board is accurately stopped in the action area of ​​the fixing mechanism 7.

[0044] Please see Figure 1 , Figure 2 and Figure 3The tapping mechanism 10 includes a bottom slider 1001, which is slidably connected to a bottom second linear module 9. A bottom electric push rod 1002 is fixedly installed on the upper surface of the bottom slider 1001, and an electric tapping machine 1003 is installed at the output end of the bottom electric push rod 1002. The bottom second linear module 9 can drive the electric tapping machine 1003 to accurately position the tapping position along the X-axis. The bottom electric push rod 1002 controls the tapping depth by extending and retracting in the Z-axis direction. After the drilling mechanism 13 completes the machining of the current hole, the tapping mechanism 10 immediately performs tapping operations on the completed drilled hole, forming a composite machining process that significantly improves the single-station machining efficiency. Two top first linear modules 11 are installed on the inner top wall of the machining truss 1. The bottom of the two first linear modules 11 is slidably connected to a top second linear module 12. A drilling mechanism 13 is set below the top second linear module 12. The drilling mechanism 13 and the tapping mechanism 10 can directly tap the holes after drilling, reducing subsequent production steps. During the process of opening subsequent holes, the drilling mechanism 13 can tap the holes in the already drilled area, improving production efficiency. The drilling mechanism 13 includes a top slider 1301, which is slidably connected to the top second linear module 12. A top electric push rod 1302 is fixedly installed at the bottom of the top slider 1301. An electric drilling machine 1303 is installed at the output end of the top electric push rod 1302. The top second linear module 12 and the top electric push rod 1302 form X and Z dual-axis motion, which allows the electric drilling machine 1303 to adjust the hole position along the length of the board and control the drilling depth through vertical feed. This mechanism and the tapping mechanism 10 form a coordinated operation mode, completing the drilling and tapping processes simultaneously during the board conveying process, reducing secondary clamping errors.

[0045] The working principle of the above embodiment is as follows: the bidirectional lead screw 14 rotates under the drive of the power source, driving the two conveyor plates 2 to move towards each other along the guide rod 15. The spacing of the conveyor plates 2 is adjusted so that the support protrusion 201 contacts the side of the plate, forming an adaptive clamping channel. The operator places the basketball backboard between the two conveyor plates 2. The conveyor belt 4 is driven synchronously by the motor 16. Each set of conveyor belts 4 consists of two conveyor shafts 3 and pulleys 5. The support protrusion 201 provides a rigid support surface for the conveyor belt 4, ensuring that the plate remains horizontal during the conveying process. The electric slide rail 601 drives the detection block 602 to move towards the plate. When the two photoelectric switches 603 simultaneously detect the edge signal of the plate, the two conveyor motors 16 are stopped synchronously, so that the plate is accurately stopped in the action area of ​​the fixing mechanism 7. The cylinder 702 drives the clamping block 703 to form a mechanical engagement with the plate. The top second linear module 12 drives the electric drilling machine 1303 to move along the X-axis, the top first linear module 11 drives the electric drilling machine 1303 to move along the Y-axis, and the top electric push rod 1302 controls the Z-axis feed of the drill bit to realize the drilling work on the plate. The bottom first linear module 8 and the bottom second linear module 9 drive the electric tapping machine 1003 to follow the drilling position synchronously, and the bottom electric push rod 1002 pushes the electric tapping machine 1003 to perform tapping work.
