Abstract
Description
Technical Field
[0001] This utility model application belongs to the field of T-iron drilling technology, specifically relating to a device for drilling T-iron. Background Technology
[0002] A loudspeaker, also known as a "horn," is a transducer that converts electrical signals into sound signals. The T-iron is the base of the loudspeaker, also called electrical iron, and is a crucial component of the speaker enclosure. Its quality directly affects the sound quality of the speaker. It is made of pure iron and is a component of the sound unit.
[0003] In the machining process of T-iron, drilling is a step that involves drilling holes. To improve drilling efficiency, designers in this field often install multiple drill bits on each drilling machine, increasing the number of workstations to enhance efficiency. However, the design of multiple drill bits per machine also results in significant power consumption for the entire machine during machining operations, as each drill bit needs to reach a high rotational speed.
[0004] Therefore, there is an urgent need to design a new T-iron drilling device to solve the current technical problems. While ensuring the drilling efficiency of each machine, it can also greatly reduce the power consumption of the whole machine, so as to achieve the technical effect of keeping each drilling machine at a low power consumption level during normal operation. This will fully meet the requirements of low energy consumption for mass production of T-irons in industry, thereby reducing the production cost of enterprises and ultimately improving economic efficiency. Utility Model Content
[0005] This utility model application discloses a device for drilling holes in T-iron, in order to solve the problems existing in the prior art.
[0006] To achieve the above objectives, this utility model provides a device for drilling T-iron, including a fixed platform for placing and fixing the T-iron, and a lifting platform fixedly mounted on the fixed platform, on which a horizontally arranged lifting plate is installed, the lifting plate being capable of vertical reciprocating lifting and lowering along the lifting platform; a drilling mechanism mounted on the lifting plate, including: a plurality of drill bits rotatably disposed at the bottom of the lifting plate; a motor, one of which is disposed above the lifting plate; and a transmission structure mounted on the lifting plate between the motor and the plurality of drill bits, for transmitting the kinetic energy of the motor to each drill bit.
[0007] Furthermore, the transmission structure includes: a drive shaft, vertically mounted on the lifting plate, with its top fixedly connected to the output end of the motor, and a drill bit at its bottom; a drive wheel, coaxially fixedly mounted on the drive shaft; two driven wheels, meshing with the two ends of the drive wheel respectively, with a horizontal driven shaft coaxially connected to the outer end of each driven wheel, and a first bevel gear coaxially fixedly mounted on the outer end of each horizontal driven shaft; and two second bevel gears, meshing with the lower ends of the two first bevel gears respectively, with a vertical driven shaft coaxially fixedly mounted on each second bevel gear, and a drill bit at the bottom of each vertical driven shaft.
[0008] Furthermore, all driven gears are bevel gears.
[0009] Furthermore, all driven gears are crown gears.
[0010] Furthermore, the driven gear is a curved crown gear, and the driving gear is a curved bevel gear that matches the curved crown gear.
[0011] Furthermore, the device also includes several material handling mechanisms installed on one side of the fixed platform; the material handling mechanism includes a mounting platform on which an operating arm is mounted for feeding and picking up materials.
[0012] Furthermore, the operating arms are mounted on the mounting platform on the side opposite to the fixed platform. One end of each operating arm is connected to the mounting platform, and the other end is equipped with an electromagnetic chuck. A drive cylinder is mounted on the other side of the mounting platform, and the mounting platform is fixedly connected to the telescopic end of the drive cylinder.
[0013] Furthermore, a telescopic cylinder is installed on the mounting platform, and the mounting platform is connected to the operating arm through the telescopic cylinder; the telescopic end of the telescopic cylinder is fixedly connected to the operating arm, allowing the operating arm to extend or retract.
[0014] Furthermore, the device also includes gratings, which are fixedly mounted on both sides of the fixed platform.
[0015] Furthermore, a lifting cylinder is installed on the lifting platform to drive the lifting plate to rise and fall.
[0016] The advantages and positive effects of this utility model are:
[0017] 1. The T-iron drilling device disclosed in this utility model application requires only one motor. The motor uses a transmission structure to transfer kinetic energy to each drill bit, thereby driving several drill bits to rotate clockwise for drilling. In this technical solution, one motor can drive several drill bits, eliminating the need for a corresponding motor for each drill bit. This solution, while ensuring drilling efficiency, greatly reduces the power consumption of the entire device, achieving the technical effect of maintaining a low power consumption level during normal operation of each drilling device. This fully meets the low energy consumption requirements of large-scale T-iron processing in industry, thereby reducing enterprise production costs and ultimately improving economic efficiency.
[0018] 2. The T-iron drilling device disclosed in this utility model application typically uses a bevel gear as the driving wheel. Utilizing the characteristic of bevel gears to change the transmission direction, the driving wheel transmits kinetic energy to the driven wheels on both sides. With the shaft angle being 90 degrees, the driven wheels rotate in the horizontal direction, thereby driving the drill bits on both sides of the driving wheel to rotate clockwise. A single motor can drive the rotation of three drill bits, thus achieving the effect of saving energy.
[0019] 3. The T-iron drilling device disclosed in this utility model application uses a curved tooth structure for the drive wheel. When meshing, multiple teeth mesh simultaneously, resulting in a large contact area and extremely smooth transmission. At the same time, the progressive meshing connection method can reduce vibration during transmission compared to straight tooth structure transmission, thus minimizing noise. The tooth surface wear is uniform, making it more durable, with less wear and high transmission efficiency, making it suitable for transmissions with higher speeds or heavier loads.
[0020] 4. The T-iron drilling device disclosed in this utility model application uses a helical gear structure for the drive wheel. This results in a larger contact area during meshing, leading to a smoother transmission compared to a spur gear structure, which provides a more gradual meshing connection. It also reduces vibration and noise during transmission, and the tooth surface wear is more uniform, making it more durable than spur gears. Furthermore, it is easier to manufacture than curved bevel gears, resulting in lower production costs. Therefore, the helical gear structure offers performance between spur and curved gear structures and is the most cost-effective option.
[0021] 5. The T-iron drilling device disclosed in this utility model application is also equipped with a material handling mechanism, which makes the device more automated and saves more manpower.
[0022] 6. The T-iron drilling device disclosed in this utility model application is equipped with optical gratings, which are fixedly mounted on both sides of the fixed platform. The optical gratings serve as a mistake-proof design, further protecting the safety of the operator.
[0023] 7. The technical solution disclosed in this utility model application has the advantages of simple structure, low energy consumption, strong connection, sturdy and durable, stable performance, easy to use, easy to manufacture, low cost, and safe and reliable. Attached Figure Description

[0031] The specific embodiments of this utility model application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.
[0032] In the technical solutions disclosed in this utility model application, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to those defined based on the drawing direction of the corresponding figures, while "inner" and "outer" refer to those inside and outside relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the figures, the same reference numerals in different figures denote the same element.
[0033] According to this utility model application, a device for drilling holes in T-iron is disclosed, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes a fixed platform 8 for placing and fixing the T-iron 7, and also includes a lifting platform 1, which is fixed on the fixed platform 8. A horizontally set lifting plate 4 is installed on the lifting platform 1, and the lifting plate 4 can move vertically back and forth along the lifting platform 1.
[0034] The drilling mechanism, mounted on the lifting plate 4, includes:
[0035] Several drill bits 11 are rotatably mounted at the bottom of the lifting plate 4;
[0036] Motor 3, one in number, is located above the lifting plate 4;
[0037] The transmission structure 6 is installed on the lifting plate 4 between the motor 3 and several drill bits 11, and is used to transmit the kinetic energy of the motor 3 to each drill bit 11.
[0038] In the above technical solution, only one motor 3 is required. The motor 3 can transmit kinetic energy to each drill bit 11 through the transmission structure 6, thereby driving several drill bits 11 to rotate clockwise (clockwise refers to the observation angle from the operator looking down at the T-iron, which is also a conventional requirement of the processing technology in this field). Regarding drilling holes in the T-iron 7, it should be specifically noted that there are several drill bits 11, including two, three, or even more if the motor 3 has sufficient power, while only one motor 3 is required at most. In this scheme, a motor 3, several drill bits 11, and a transmission structure 6 constitute a basic drilling unit. In actual work, the designer can also set more than one drilling unit on a device according to the working conditions, that is, set more than one motor 3, so as to drive more drill bits 11 to rotate and drill. The drilling mechanism is installed on the lifting plate 4, which can realize the function of vertical reciprocating lifting and lowering along the lifting platform 1. During the drilling process, the drilling mechanism moves downward through the lifting platform 1 to drill the T-iron 7. After the drilling is completed, the drilling mechanism moves upward through the lifting platform 1 so that the relevant operators or material handling equipment can take out the processed T-iron 7. This technical solution uses a single motor 3 to drive several drill bits 11, eliminating the need for a separate motor 3 for each drill bit 11. This significantly reduces the overall power consumption of the device while maintaining drilling efficiency, achieving the technical effect of keeping each drilling machine at a low power consumption level during normal operation. This fully meets the low energy consumption requirements for mass production of T-iron in industry, thereby reducing enterprise production costs and ultimately improving economic efficiency.
[0039] In this embodiment, such as Figure 3 , Figure 4 As shown, the transmission structure 6 includes:
[0040] The drive shaft 607 is vertically mounted on the lifting plate 4, and the top of the drive shaft 607 is fixedly connected to the output end of the motor 3. The bottom of the drive shaft 607 is provided with a drill bit 11.
[0041] The drive wheel 601 is coaxially fixed on the drive shaft 607;
[0042] There are two driven wheels 602, which mesh with the two ends of the driving wheel 601 respectively. Each driven wheel 602 has a horizontal driven shaft 606 coaxially connected to its outer end. Each horizontal driven shaft 606 has a first bevel gear 603 coaxially fixed to its outer end.
[0043] There are two second bevel gears 604, which mesh with the lower ends of the two first bevel gears 603 respectively. Each second bevel gear 604 has a vertical driven shaft 605 that is coaxially fixed on it and passes through the lifting plate 4. Each vertical driven shaft 605 has a drill bit 11 below it.
[0044] In this design, the driving gear 601 is typically a bevel gear. Utilizing the bevel gear's ability to change the transmission direction, the driving gear 601 can transmit kinetic energy to the driven gears 602 on both sides. The shaft angle is 90 degrees, allowing the driven gears 602 to rotate horizontally. This, in turn, drives the drill bits 11 on both sides of the driving gear 601 to rotate clockwise. The drill bit 11 at the bottom of the driving shaft 607 can also rotate clockwise with the driving shaft 607. Ultimately, all drill bits 11 achieve clockwise drilling. The specific design is as follows:
[0045] like Figure 3 As shown, the driving gear 601 is a bevel gear, and the driven gear 602 is also a bevel gear.
[0046] Example (1)
[0047] The driving gear 601 is a straight bevel gear, and the two driven gears 602 are both straight bevel gears that match the driving gear 601, with a shaft intersection angle of 90 degrees;
[0048] Example (2)
[0049] The driving gear 601 is a curved bevel gear, and both driven gears 602 are also curved bevel gears that match the driving gear 601, with a shaft intersection angle of 90 degrees. By changing the tooth groove to a curved tooth structure, multiple teeth mesh simultaneously during engagement, resulting in a large contact area and extremely smooth transmission. At the same time, the progressive meshing connection method reduces vibration during transmission compared to straight bevel gears, minimizing noise. The uniform tooth surface wear makes it more durable, with less wear consumption and high transmission efficiency, making it suitable for high-speed or heavy-load transmissions.
[0050] Example (3)
[0051] The driving gear 601 is a helical bevel gear, and both driven gears 602 are helical bevel gears matched with the driving gear 601, with a shaft intersection angle of 90 degrees. By changing the tooth groove to a helical tooth structure, the contact area during meshing is larger, resulting in a smoother meshing connection compared to straight bevel gear transmissions. It also reduces vibration and noise during transmission; tooth surface wear is more uniform, making it more durable than spur gears; furthermore, it is easier to manufacture than curved bevel gears, resulting in lower production costs. Therefore, helical bevel gears, with performance falling between straight bevel gears and curved bevel gears, represent the most cost-effective choice.
[0052] like Figure 4 As shown, the driving gear 601 is a bevel gear, and the driven gear 602 is a crown gear.
[0053] Example (4)
[0054] The driving gear 601 is a straight bevel gear, and the two driven gears 602 are straight crown gears that match the driving gear 601, with a shaft intersection angle of 90 degrees;
[0055] Example (5)
[0056] The driving gear 601 is a curved bevel gear, and the two driven gears 602 are curved crown gears that match the driving gear 601, with a shaft angle of 90 degrees. Changing the tooth groove to a curved tooth structure has a similar principle and beneficial effect to embodiment (2), that is, multiple teeth mesh simultaneously during meshing, resulting in the largest contact area and extremely smooth transmission; at the same time, the progressive meshing connection method can reduce vibration during transmission compared to straight crown gears, and can minimize noise; the tooth surface wear is uniform, making it more durable, and the wear consumption is small, resulting in high transmission efficiency, which is suitable for transmissions with higher speeds or heavier loads.
[0057] Example (6)
[0058] The driving gear 601 is a helical bevel gear, and the two driven gears 602 are both helical bevel gears that match the driving gear 601, with a shaft intersection angle of 90 degrees. The tooth groove is changed to a helical tooth structure, and the principle and beneficial effects are similar to those of embodiment (3): the contact area is larger during meshing, and the relatively progressive meshing connection method is smoother than the straight crown gear transmission; at the same time, it can reduce vibration and noise during transmission; the tooth surface wear is more uniform, making it more durable than the straight gear; and the processing difficulty is less than that of the curved crown gear, resulting in a relatively lower production cost. It can be seen that the helical crown gear is between the straight crown gear and the curved crown gear in terms of performance, and is the most cost-effective choice.
[0059] In other implementations, such as Figure 2 , Figure 5As shown, this device also includes several material handling mechanisms 9, installed on one side of the fixed platform 8; each material handling mechanism 9 includes a mounting platform 903, on which an operating arm 901 is mounted for material handling and unloading (i.e., for T-iron 7). In this design, the material handling mechanisms 9 enhance the automation level of the device and further reduce manpower costs. The specific design is as follows:
[0060] Example (7)
[0061] like Figure 2 , Figure 5 As shown, the operating arm 901 is mounted on the mounting platform 903 and is on the side opposite to the fixed platform 8. One end of each operating arm 901 is connected to the mounting platform 903, and the other end is equipped with an electromagnetic chuck.
[0062] A drive cylinder 904 is installed on the other side of the mounting platform 903, and the mounting platform 903 is fixedly connected to the telescopic end of the drive cylinder 904.
[0063] In this embodiment, the number of material handling mechanisms 9 corresponding to the number of drill bits 11 can be set for the operating arm 901. The operating arm 901 is mounted on the mounting table 903 and can achieve reciprocating lifting and lowering motion in the horizontal direction using the drive cylinder 904. During drilling, the drive cylinder 904 retracts, the operating arm 901 moves away from the fixed table 8, and the T-iron 7 is drilled. After drilling is completed, the drive cylinder 904 extends, the operating arm 901 moves horizontally towards the fixed table 8, and the processed T-iron 7 is removed using an electromagnetic chuck. In addition, a slide rail can be installed on the mounting table 903 to ensure that the operating arm 901 is accurately positioned relative to the T-iron 7, thus ensuring the accuracy of the drilling process.
[0064] Example (8)
[0065] like Figure 2 , Figure 5 As shown, based on embodiment (7), a telescopic cylinder 902 is also installed on the mounting platform 903, and the mounting platform 903 is connected to the operating arm 901 through the telescopic cylinder 902.
[0066] The telescopic end of the telescopic cylinder 902 is fixedly connected to the operating arm 901, allowing the operating arm 901 to extend or retract. The dual-drive design of the telescopic cylinder 902 and the drive cylinder 904 increases the mobility and flexibility of the material handling mechanism 9, enabling the device to have more usage options: a material conveyor belt can be set between the fixed platform 8 and the material handling mechanism 9. The mounting platform 903 is first moved to the side of the conveyor belt using the drive cylinder 904, and the T-iron 7 is taken off the conveyor belt by the operating arm 901. Then, the telescopic cylinder 902 is used to transport the T-iron 7 to the fixed platform 8, making the operation more convenient.
[0067] In some other implementations, such as Figure 1 , Figure 2 As shown, the device also includes gratings 10, which are fixedly mounted on both sides of the fixed platform 8. The gratings 10 serve as a fault-prevention design, further protecting the safety of the operator.
[0068] There are also other implementation methods, such as Figure 1 , Figure 2 As shown, a lifting cylinder 2 is installed on the lifting platform 1 to drive the lifting plate 4 to rise and fall.
[0069] It is worth mentioning that this utility model application focuses on solving how to achieve high-efficiency drilling at multiple stations with low energy consumption. Some other technical details can refer to and adopt designs in existing technologies. For example, the T-iron 7 can be fixed by the fixed platform 8 using existing clamps, and the T-iron 7 can be clamped by tightening the bolts on the clamps. There are many other methods besides these, which will not be elaborated here.
[0070] This utility model application exemplarily describes the operation steps of the device, as follows:
[0071] S1. When the lifting cylinder 2 is working, the drilling mechanism rises with the lifting plate 4, and the operator / material handling mechanism 9 places several T-irons 7 on the fixed platform 8 at the corresponding positions.
[0072] S2. The operator / material handling mechanism 9 moves away from the fixed platform 8, the drilling mechanism descends with the lifting plate 4, and at the same time each drill bit 11 rotates clockwise to drill holes;
[0073] S3. After drilling is completed, the drilling mechanism rises with the lifting plate 4, and the operator / material handling mechanism 9 takes the processed T-iron 7 from the fixed table 8, and the operation is completed.
[0074] S4. Repeat the above operation to drill holes in the next batch of T-iron.
[0075] The preferred embodiments of this utility model application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the disclosed technical concept, various simple modifications can be made to the technical solution of this utility model application, and these simple modifications all fall within the protection scope of this application. For example, a housing 5 is installed on the outside of the transmission structure 6.
[0076] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction, such as replacing the pneumatic cylinder with a hydraulic cylinder. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.
[0077] Furthermore, various different embodiments of this utility model application can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this utility model application.
