Description

Technical Field

[0001] The utility model relates to the technical field of equipment manufacturing, in particular to a main shaft front driving transmission structure for single-hole deep hole drilling. Background Art

[0002] The current deep hole boring machine, such as a deep hole blind hole boring machine disclosed in patent number CN214488938U, includes a processing machine tool, a first fixed part, a fixing fixture, a gear box and a second fixed part are provided above the processing machine tool, and a horizontal slide rail is provided on the upper surface of the processing machine tool, a hydraulic cylinder is fixedly installed on the first fixed part, a positioning pin is provided at the end of the piston rod of the hydraulic cylinder, the fixing fixture includes an annular frame and a support frame, a number of fasteners are provided on the annular frame, the gear box is slidably connected to the horizontal slide rail through a sliding part, a plurality of blow pipes are provided at the lower part of the left side wall of the gear box, a motor is installed on the right side wall of the gear box, the output shaft of the motor is transmission-connected to the input shaft of the gear box, the output shaft of the gear box is connected to the cutter shaft through a universal joint, two synchronous cylinders are fixedly installed on the second fixed part, and the piston rods of the two synchronous cylinders are fixedly connected to the outer box body of the gear box.

[0003] That is, the current transmission structure in the boring machine is a gearbox transmission structure. When the processing aperture changes from 40 to 200mm, the speed also needs to change. To control the speed, it is necessary to manually turn the gearbox shift paddle to adjust the meshing relationship of the gears, thereby changing the spindle speed. When the gear reaches a certain fatigue strength and is damaged, the entire gear set needs to be removed for maintenance, and the replacement time of a single gear often exceeds 16 working hours.

[0004] Moreover, there are many parts involved in the production and processing of gearboxes. A gearbox is composed of nearly 100 parts. The quality control requirements in the production process are relatively high. In the assembly process, the assembly of more than 100 parts requires relatively high requirements for assembly workers, and the assembly time is also relatively high. 3. During use, when switching gears, if the speed has not completely stopped, the shift gear will play, thereby damaging the gear, and the requirements for users are also relatively high.

The structure adopts a drive structure in which the drive motor 20 and the spindle 40 are connected and driven, and stepless speed change is performed by changing the motor rate to meet the processing requirements.

[0028] Specifically, the base 10 has an upper mounting surface 11 and a side mounting surface 12, and the upper mounting surface 11 and the side mounting surface 12 are arranged on two different planes. The upper mounting surface 11 and the side mounting surface 12 can be arranged vertically, that is, the upper mounting surface 11 is arranged horizontally and the side mounting surface 12 is arranged vertically. The drive motor 20 and the drive assembly are arranged in parallel on the upper mounting surface 11, and the main shaft 40 is arranged on the side mounting surface 12.

[0029] Here, the driving motor 20 has an output end 21 , and a synchronous pulley is provided on the output end 21 .

[0030] Correspondingly, the linkage assembly 30 includes a linkage base 31 and an input member 32 and an output member 33 arranged at opposite ends of the linkage base 31. The linkage base 31 is a box structure, and the input member 32 and the output member 33 are exposed on the outside of the linkage base 31. The input member 32 and the output member 33 are connected through a shaft transmission, and the shaft is located inside the linkage base 31. The input member 32 and the output member 33 use synchronous pulleys.

[0031] Here, the output end 21 of the driving motor 20 is connected to the input part 32 through a synchronous belt transmission, and the output part 33 is connected to the main shaft 40 through a synchronous belt transmission.
