[0002] Aluminum alloy profiles are metal structural materials made by adding alloying elements to aluminum. They belong to the category of non-ferrous metals and are mainly used in machinery manufacturing, transportation machinery, aerospace industry and construction.

[0003] In aluminum profile tapping, the tapping head is a single unit. Therefore, a single tapping operation can only produce one threaded hole. If multi-hole tapping is required, multiple tapping operations are necessary, and a two-axis device is required as the drive source. The time consumed by the drive stroke plus the time of multiple tapping operations will lead to low production efficiency. To avoid the above situation, it is necessary to provide an automated aluminum profile tapping device with higher efficiency. Summary of the Invention

[0004] This utility model provides an automated aluminum profile tapping device, which aims to solve the problem that in the aluminum profile tapping process, the tapping head is a single unit, so a single tapping operation can only produce one screw hole. If multi-hole tapping is required, multiple tapping operations are required, and a two-axis device is needed as the drive source. The time consumed by the drive stroke plus the time of multiple tapping operations will lead to low production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automated aluminum profile tapping device includes an outer operating frame assembly and a crossbar: the outer wall of the crossbar is provided with a tapping assembly, the tapping assembly includes a horizontal slide seat slidably disposed on the outer wall of the crossbar, the bottom of the horizontal slide seat is fixedly connected to an upper hanger, the bottom of the upper hanger is fixedly connected to a drive motor, the bottom of the upper hanger is fixedly connected to a connecting platform, the inner wall of the connecting platform is provided with a main tapping mechanism and a secondary tapping mechanism, and a transmission chain connects the main tapping mechanism and the secondary tapping mechanism; The main tapping mechanism includes a connecting rod, the lower end of which is threaded with a transverse pin, which passes through the tapping drill bit and securely connects the tapping drill bit and the connecting rod.

[0006] Preferably, the output shaft of the drive motor is fixedly connected to the top of the main tapping mechanism via a coupling.

[0007] Preferably, the connecting rod includes a connecting rod, a transmission gear is fixedly connected to the top of the connecting rod, and a limit ring is fixedly connected to the outer wall of the connecting rod.

[0008] Preferably, there are multiple auxiliary tapping mechanisms, and the internal structure of the auxiliary tapping mechanisms is the same as that of the main tapping mechanism.

[0009] Preferably, the outer wall of the connecting platform is provided with several connecting slots, and the several connecting slots are arranged in an equidistant array.

[0010] Preferably, the inner wall of the connecting groove is embedded with several balls, and the inner wall of the connecting groove is rolledly connected to the outer wall of the limiting ring through the balls.

[0011] Preferably, there are two external operating frame assemblies, and the two external operating frame assemblies are symmetrically arranged on both sides of the crossbar; The external operating frame assembly includes a chassis, a vertical frame fixedly connected to the top of the chassis, a lifting hydraulic cylinder fixedly connected to the top of the chassis, a vertical slide seat slidably connected to the outer wall of the vertical frame, one end of the lifting hydraulic cylinder being fixedly connected to the bottom of the vertical slide seat, and a positioning hole provided on the outer wall of the chassis.

[0012] Preferably, a telescopic hydraulic cylinder is fixedly connected to the outer wall of the vertical slide block, and one end of the telescopic hydraulic cylinder is fixedly connected to the outer wall of the horizontal slide block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By designing the tapping assembly: This utility model's tapping assembly achieves synchronous tapping operations with multiple drill bits under a single motor drive through a chain drive combination of a main tapping mechanism and multiple auxiliary tapping mechanisms. The drive motor rotates the main tapping mechanism, which in turn drives all auxiliary tapping mechanisms synchronously via the transmission chain, enabling multiple tapping drill bits to work simultaneously and complete the machining of multiple threaded holes in one operation. This completely solves the problem of low efficiency and multiple operations required by traditional single-head tapping. The connecting platform adopts a modular design, flexibly configuring the number of auxiliary tapping mechanisms through equidistant array connecting slots to adapt to different hole spacing requirements. The cooperation between the limiting ring and the ball bearings ensures smooth transmission, balancing high efficiency and flexibility, and significantly improving the production efficiency of multi-hole tapping of aluminum profiles. The external operating frame assembly in this invention achieves rapid and precise positioning of the tapping assembly in both the horizontal and vertical directions through symmetrically arranged vertical frames, lifting hydraulic cylinders, and telescopic hydraulic cylinders. Specifically, the telescopic hydraulic cylinder drives the horizontal slide block to move along the horizontal frame rod, completing the horizontal position adjustment; the lifting hydraulic cylinder pushes the vertical slide block to rise and fall along the vertical frame, achieving vertical feed control. This bidirectional adjustment mechanism significantly shortens the alignment time before tapping, overcoming the problems of long drive strokes and long time consumption in traditional two-axis equipment. Simultaneously, the chassis is fixed to the external platform through positioning holes, ensuring overall operational stability, further improving tapping accuracy and repeatability, and providing a fundamental guarantee for efficient continuous processing.

[0020] An automated aluminum profile tapping device includes an outer operating frame assembly 1 and a crossbar 3. A tapping assembly 2 is provided on the outer wall of the crossbar 3. The tapping assembly 2 includes a horizontal slide seat 201 slidably disposed on the outer wall of the crossbar 3. An upper hanger 204 is fixedly connected to the bottom of the horizontal slide seat 201. A drive motor is fixedly connected to the bottom of the upper hanger 204. A connecting platform 206 is fixedly connected to the bottom of the upper hanger 204. A main tapping mechanism 203 and a secondary tapping mechanism 205 are provided on the inner wall of the connecting platform 206. A transmission chain 202 connects the main tapping mechanism 203 and the secondary tapping mechanism 205. The main tapping mechanism 203 includes a connecting rod 2032. The lower end of the connecting rod 2032 is threaded with a transverse pin, which passes through the tapping drill bit 2031 and fastens the tapping drill bit 2031 and the connecting rod 2032.

[0021] The output shaft of the drive motor is fixedly connected to the top of the main tapping mechanism 203 via a coupling.

[0022] The connecting rod 2032 includes a connecting rod 2032-a, a transmission gear 2032-b fixedly connected to the top of the connecting rod 2032-a, and a limit ring 2032-c fixedly connected to the outer wall of the connecting rod 2032-a.

[0023] There are multiple auxiliary tapping mechanisms 205, and the internal structure of the auxiliary tapping mechanism 205 is the same as that of the main tapping mechanism 203.

[0024] The outer wall of the connecting platform 206 has several connecting slots, and the connecting slots are arranged in an equidistant array.

[0025] Several balls are embedded in the inner wall of the connecting groove, and the inner wall of the connecting groove is connected to the outer wall of the limiting ring 2032-c by the balls in a rolling connection.

[0026] It should be noted that, in the current tapping process for aluminum profiles, the tapping head is a single unit. Therefore, a single tapping operation can only produce one screw hole. If multi-hole tapping is required, multiple tapping operations are necessary, and a two-axis device must be used as the drive source. The time consumed by the drive stroke, plus the time spent on multiple tapping operations, will lead to a decrease in production efficiency.

[0027] Specifically, in this embodiment, the solution mainly utilizes the setup and coordination of the external operating frame assembly 1, the tapping assembly 2, and the crossbar 3. During use, according to the tapping requirements, the auxiliary tapping mechanism 205 is installed on the connecting base 206 via the connecting groove. The transmission gears 2032-b on the main tapping mechanism 203 and the auxiliary tapping mechanism 205 are meshed together via the transmission chain 202, completing the setup of the tapping assembly 2. The aluminum material to be tapped is placed below the tapping assembly 2 and fixed in place. Then, the telescopic hydraulic cylinder 104 is started and controlled. At this time, one of the telescopic cylinders... One hydraulic cylinder 104 extends outward, while another hydraulic cylinder 104 retracts, thereby allowing for lateral adjustment of the tapping assembly 2 so that it aligns with the hole to be drilled on the aluminum material. The lifting hydraulic cylinder 103 controls the synchronous vertical adjustment of the tapping assembly 2. When the drive motor rotates the main tapping mechanism 203, it simultaneously rotates the auxiliary tapping mechanism 205, which in turn rotates the drill bit on the auxiliary tapping mechanism 205 to perform the tapping operation. The main tapping mechanism 203 and multiple auxiliary tapping mechanisms 205 perform the tapping operation simultaneously.

[0028] In this embodiment, the tapping assembly 2 achieves synchronous tapping of multiple drill bits under a single motor drive through a chain drive combination of a main tapping mechanism and multiple auxiliary tapping mechanisms. The drive motor rotates the main tapping mechanism, which in turn drives all auxiliary tapping mechanisms synchronously via the transmission chain, enabling multiple tapping drill bits to work simultaneously and complete the processing of multiple threaded holes at once. This completely solves the problem of low efficiency and multiple operations required by traditional single-head tapping. The connecting platform adopts a modular design, flexibly configuring the number of auxiliary tapping mechanisms through equidistant array connecting slots to adapt to different hole spacing requirements. The cooperation between the limiting ring and the ball bearings ensures smooth transmission, balancing high efficiency and flexibility, and significantly improving the production efficiency of multi-hole tapping of aluminum profiles.

[0029] In a further preferred embodiment of this utility model, there are two external operating frame assemblies 1, and the two external operating frame assemblies 1 are symmetrically arranged on both sides of the crossbar 3. The external operating frame assembly 1 includes a chassis 105, a vertical frame 101 fixedly connected to the top of the chassis 105, a lifting hydraulic cylinder 103 fixedly connected to the top of the chassis 105, a vertical slide seat 102 slidably connected to the outer wall of the vertical frame 101, one end of the lifting hydraulic cylinder 103 fixedly connected to the bottom of the vertical slide seat 102, and a positioning hole is provided on the outer wall of the chassis 105.

[0030] A telescopic hydraulic cylinder 104 is fixedly connected to the outer wall of the vertical slide seat 102, and one end of the telescopic hydraulic cylinder 104 is fixedly connected to the outer wall of the horizontal slide seat 201.

[0031] In this embodiment, the external operating frame assembly 1 achieves rapid and precise positioning of the tapping assembly in both the horizontal and vertical directions through symmetrically arranged vertical frames, lifting hydraulic cylinders, and telescopic hydraulic cylinders. Specifically, the telescopic hydraulic cylinder 104 drives the horizontal slide block to move along the horizontal frame rod, completing the horizontal position adjustment; the lifting hydraulic cylinder pushes the vertical slide block to rise and fall along the vertical frame, achieving vertical feed control. This bidirectional adjustment mechanism significantly shortens the alignment time before tapping, overcoming the problems of long drive strokes and long time consumption in traditional two-axis equipment. At the same time, the chassis is fixed to the external platform through positioning holes, ensuring overall operational stability, further improving tapping accuracy and repeatability, and providing a basic guarantee for efficient continuous processing.
