Automatic drilling equipment used for machining radial holes of sleeve parts

Abstract

The invention relates to the technical field of sleeve part machining, in particular to automatic drilling equipment used for machining radial holes of sleeve parts. The automatic drilling equipment comprises a dual-station sliding assembly, a first rotating assembly, a second rotating assembly, three-claw elastic positioning assemblies, adjustable expansion claws, a gantry suspension assembly and a drilling assembly. The first rotating assembly and the second rotating assembly are arranged at the dual working ends of the dual-station sliding assembly correspondingly. The three-claw elastic positioning assemblies are coaxially arranged at the working ends of the rotating assemblies. The adjustable expansion claws are evenly distributed at the working ends of the three-claw elastic positioning assemblies along the axis, the adjustable expansion claws comprise expansion rods, first kidney-shaped grooves in the radial direction are formed in the expansion rods, abutting joint pieces are further arranged on the expansion rods along the axes, mounting rods capable of vertically ascending and descending in the axial direction are arranged at the working ends of the abutting joint pieces, and drill bushings which can slide and are arranged in the radial direction of the sleeve parts are also arranged on the mounting rods in a sliding manner. The gantry suspension assembly is arranged on one side of the dual-station sliding assembly. The drilling assembly is arranged at the working end of the gantry suspension assembly. The equipment can accurately and stably position sleeve parts of different sizes.

Description

technical field [0001] The invention relates to the technical field of sleeve parts processing, in particular to an automatic drilling device for machining radial holes of sleeve parts. Background technique [0002] Sleeve parts are a common workpiece. According to different uses, the outer wall of some sleeve parts has multiple holes along the radial direction of the sleeve parts. After turning the main body of the sleeve parts, it needs to be drilled Drilling usually uses a chuck to fix the sleeve parts and then turns the hole. However, no matter whether internal fixation or external fixation is adopted, the contact range between the chuck and the sleeve parts is limited. The impact force will cause the deformation of the sleeve parts. For the sleeve parts with high precision requirements, the sleeve parts need to be corrected after drilling, which leads to low manufacturing efficiency and high cost.

[0002] Sleeve parts are a common workpiece. According to different uses, the outer wall of some sleeve parts has multiple holes along the radial direction of the sleeve parts. After turning the main body of the sleeve parts, it needs to be drilled Drilling usually uses a chuck to fix the sleeve parts and then turns the hole. However, no matter whether internal fixation or external fixation is adopted, the contact range between the chuck and the sleeve parts is limited. The impact force will cause the deformation of the sleeve parts. For the sleeve parts with high precision requirements, the sleeve parts need to be corrected after drilling, which leads to low manufacturing efficiency and high cost.

[0003] Chinese patent CN202010512662.2 discloses a drilling machine positioning fixture for sleeve parts, mainly related to the technical field of machine tool fixtures; including a support plate, one side of the support plate is centered on the center of the side of the support plate, and the annular array is equipped with A plurality of chute, each of which is provided with a first slider and a second slider, the middle part of the side of the first slider away from the support plate is horizontally provided with an inner support plate, the inner The middle part of the support plate is provided with a waist-shaped hole along the length direction of the inner support plate, and a lead screw is provided in each of the chute, and a nut suitable for the lead screw is inlaid on the first slider. The middle part of the support plate is horizontally equipped with a rotating shaft and a hollow shaft; this device only relies on the inner support plate to locate and fix sleeve parts, which is prone to breakage during drilling
