Belt pulley limiting boring device based on machining

Abstract

The invention discloses a belt pulley limiting boring device based on machining. The belt pulley limiting boring device comprises a limiting assembly plate, a limiting adjusting hole is formed in the outer surface of the limiting assembly plate, the middle of the outer surface of the limiting assembly plate is movably sleeved with a fastening sleeve, and one side of the fastening sleeve is movably connected with a communicating elastic piece in a clamped mode. The other side of the communicating elastic piece is movably connected with a boring cutter special-shaped connector in a clamped mode, a limiting clamping groove is formed in the middle of the limiting assembly plate, one side of the limiting assembly plate is movably sleeved with an elastic limiting piece, the other side of the elastic limiting piece is movably sleeved with a threaded rotary knob assembly, and a communicating connector is formed in one side of the fastening sleeve. By arranging the elastic limiting piece, the threaded knob assembly and other assemblies, the boring cutter and a boring rod can be installed at the accurate positions through mutual cooperative work of a rotating connector, a connecting threaded rod, a limiting rectangular block, a movable arc-shaped plate and a stretching shaft rod in the two assemblies, and the cutter body is prevented from inclining, and the situation that the processed surface of the belt pulley hole is damaged by the boring cutter is also prevented.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, more specifically, the invention relates to a limit boring device based on a pulley for mechanical processing. Background technique [0002] The current boring is divided into general boring and deep hole boring. General boring can be done on ordinary lathes, and the boring tool can be fixed on the tailstock of the lathe or on a small tool holder. Deep hole boring requires a special deep hole drilling and boring machine. The boring tool needs to be equipped with a boring stalk, and a hydraulic pump station is added to use the coolant to remove iron filings, and the pulley also needs to be bored. [0003] However, there are still some disadvantages in its actual use, such as: [0004] 1. When the existing belt pulley is bored, components such as the boring tool and the boring bar are needed. When the boring tool is in use, the length of the boring bar is different, so that when the l...

Problems solved by technology

[0004] 1. When the existing belt pulley is bored, components such as the boring tool and the boring bar are needed. When the boring tool is in use, the length of the boring bar is different, so that when the length of the boring tool is longer, its rigidity will be increased. , resulting in bending deformation of the blade, etc., resulting in a taper error in the hole

[0005] 2. The existing boring tool and boring bar are easy to be on the same level as the pulley hole during processing, so that the phenomenon of increased vibration and knife sticking occurs, causing the lower part of the boring tool to damage the hole wall and affect the machining accuracy. In addition, the existing When the boring tool is installed, it is rarely installed to the precise position, so that the tool body is skewed, causing the boring tool to damage the machined surface of the pulley hole
