Description

Technical Field

[0001] The invention belongs to the field of aluminum busbar processing equipment, and in particular relates to a multi-hole drilling machine. Background Art

[0002] The aluminum busbar is the conductor for the current to enter and exit the electrolytic cell. The current is transmitted from the aluminum busbar to the anode guide rod through the contact surface. It sends high-power direct current, so that the high direct current passes through the electrolysis link from the positive electrode, and finally comes out from the electrolysis negative electrode to the rectifier cabinet. In the aluminum busbar processing and construction work, it is often necessary to prefabricate and process the busbar according to the actual installation location. According to the needs, some parts of the busbar will be drilled. The location of the busbar drilling varies depending on the application site and design requirements.

[0003] Ordinary drilling machines cannot directly set the drilling position and size. They need to use auxiliary tools such as steel tape measures to operate directly. When the workload is large, the measurement accuracy deviation often leads to large drilling position errors. At the same time, it is time-consuming and laborious to calibrate the drilling position size each time, and the operation efficiency is low, which is not suitable for mass production. Summary of the invention

[0004] The present invention aims to provide a multi-hole drilling machine to solve the problem that the drilling machinery in the prior art cannot be directly adjusted according to the difference in hole positions on the aluminum busbar conveniently and quickly, and the use of auxiliary tools for adjustment is time-consuming and inefficient.

[0005] A multi-hole drilling machine in this scheme includes a guide column, a lifting mechanism, a power mechanism, a transmission mechanism, a drilling mechanism and a conveying mechanism; the transmission mechanism includes a driving gear and a plurality of driven gears connected by shafts arranged in a gear box, the driving gear and the driven gear are respectively connected to a universal coupling, and the power mechanism drives the driving gear to rotate and transmits power to the universal coupling through the driven gear;

[0006] The drilling mechanism comprises a hole spacing adjustment plate and a drill clamping tube connected to the lower end of each universal coupling, the drill clamping tube is rotatably connected to the prefabricated hole set on the hole spacing adjustment plate, the drill clamping tube is connected to a drill, and there are multiple prefabricated holes on the hole spacing adjustment plate; the hole spacing adjustment plate is slidably arranged on the guide column in a detachable connection manner, and the lifting mechanism is connected to the hole spacing adjustment plate for lifting and lowering adjustment during drilling;

[0007] The conveying mechanism is located below the hole spacing adjustment plate and is used for conveying the aluminum busbar to below the drill bit.

[0008] The working principle of this scheme is: according to the number and hole spacing of the holes on the aluminum busbar, the corresponding hole spacing adjustment plate is replaced. The common number of holes currently includes 2, 3, 4 and 6 holes. The positions of these numbers of holes are set in the same row, or arranged in two rows obliquely, and there are also rectangular arrays in two rows. In this scheme, the number of universal couplings is set to 6 accordingly, and multiple universal couplings are operated simultaneously in a synchronous driving manner. The number of drill bits is installed according to the number of holes to be drilled. After replacing the hole spacing adjustment plates with the corresponding number and arrangement, the lower end of the universal coupling is connected to the drill clamping tube and then drilling is carried out.

[0009] The beneficial technical effect of this scheme is: when processing aluminum busbars of the same batch and specification, this scheme only requires replacing the hole spacing adjustment plate once, thereby achieving the effect of rapid mass production, without the need to use auxiliary tools such as tape measures for positioning each time, reducing hole position errors, and achieving the function of a drilling machine being suitable for processing a variety of hole positions and hole quantities, thereby improving production quality and efficiency as a whole.

[0010] Furthermore, the power mechanism includes a first motor and a belt transmission group driven by the first motor, and the belt transmission group is connected to the driving gear. The belt transmission can realize transmission over a long distance, has good transmission stability, and has a good buffering and shock absorbing effect. It is very suitable for processing products such as aluminum busbars that require high processing precision, and will not cause noise pollution that has a significant impact on the processing site.

[0011] Furthermore, the lifting mechanism adopts a turbine screw lifting mechanism, which has a compact structure, good transmission stability, high strength and long service life.

[0012] Furthermore, the conveying mechanism includes a drilling platform and a power-assisted roller rotatably arranged on the upper surface of the drilling platform. The aluminum busbar can be up to 14 meters in length, with a maximum cross-sectional size of 550х250mm and a large weight. When conveying it to the bottom of the drill bit, the power-assisted roller is used to assist, thereby reducing the labor output during manual pushing.

[0013] Furthermore, the conveying mechanism also includes a conveying track connected to both ends of the drilling platform, and a power-assisted roller is also rotatably arranged on the conveying track. The aluminum busbar to be drilled is placed at one end of the drilling platform, and the processed aluminum busbar is output at the other end, which reduces the waiting time when replacing the aluminum busbar to be processed, and further helps to improve the processing efficiency.

[0014] Furthermore, the conveying mechanism also includes a transmission assembly and a clamping assembly located on both sides of the aluminum busbar, the transmission assembly includes a transmission roller arranged to rotate vertically and a transmission motor driving the transmission roller to rotate; the clamping assembly includes a clamping roller arranged to rotate vertically, and the clamping roller is connected to a power cylinder driving it away from or close to the aluminum busbar. The above-mentioned use of the power-assisting roller is to assist the lower surface of the aluminum busbar, and this scheme is combined with the power-assisting on both sides of the aluminum busbar, the clamping roller and the transmission roller arranged to rotate vertically, and then combined with the transmission motor to drive, which further saves manpower for transportation and improves the comprehensive performance of the drilling machine.

[0015] Furthermore, the hole spacing adjustment plate includes an outer frame and an inner plate, the inner plate is detachably connected to the outer frame, the prefabricated holes are arranged on the inner plate, and the outer frame is slidably connected to the guide column. To customize inner plates of the same size, it is only necessary to set holes of different requirements on the independent inner plates, and bolt connection can be adopted to improve the convenience of replacing the inner plates on the outer frame.
