Portable boring device for site construction of spare and accessory parts

Abstract

The invention belongs to the technical field of machining, and particularly relates to a portable boring device for site construction of spare and accessory parts. The portable boring device for site construction of the spare and accessory parts comprises a boring machine base, wherein a spindle box and a workpiece mounting box are slidably arranged on the left side and the right side of the upper end face of the boring machine base respectively; a first boring cutter motor and a second boring cutter motor are vertically and movably arranged on the end face, directly facing the workpiece mounting box, of the spindle box; and a prefabricated hole boring cutter and a refined hole boring cutter are correspondingly arranged on the first boring cutter motor and the second boring cutter motor respectively. According to the portable boring device for site construction of the spare and accessory parts provided by the invention, through the cooperative use of the prefabricated hole boring cutter and the refined hole boring cutter, pre-boring and fine boring treatment can be carried out on one same workpiece on the same equipment on a spare and accessory part site, and one-step forming of a shaft hole can be ensured; in addition, through the special different arrangement of the prefabricated hole boring cutter and the refined hole boring cutter, the drilling and boring effects and the use strength of the cutters are improved; and on the other hand, a buffering effect is achieved in the boring process, the stability of the whole device in the using process is guaranteed, and the service life of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a portable boring device used for on-site construction of spare parts. Background technique [0002] In industries such as mining, forestry, construction, metallurgy and shipbuilding, large-scale engineering equipment is widely used. Due to the heavy load or pressure of these equipment, the borings of some key parts are easy to cause deformation and wear after a period of operation. If it is not repaired in time, the performance of large-scale engineering equipment will be gradually reduced, so that it cannot be used. The existing mechanical functions for on-site drilling and boring are relatively single. Generally, manual feeding is mainly used for drilling. The rigidity is poor and boring is difficult. For small screw holes processed on site, taps can be installed to tap them, but for slightly larger screw holes, the corresponding taps cannot be move...

Problems solved by technology

However, when the existing boring device is used in the boring operation, the workpiece must be fixed on the base corresponding to the boring tool before the boring, and then the boring tool is started to bore the prefabricated hole. When machining, the precision requirement is very high. If a workpiece needs to use a boring shaft to process multiple shaft holes, it is necessary to process one shaft hole before boring the next shaft hole, so there are several shaft holes. It requires several disassembly and assembly, which affects the processing speed. In addition, when it is necessary to process multiple shaft holes with different diameters, it is necessary to replace different boring tools, which will affect the processing efficiency on site. Therefore, it is urgent to design a tool for zero Portable boring device for on-site construction of accessories to solve the above problems
