Automatic cylinder body feed device of thin-wall drill welding machine frame

Abstract

The invention provides an automatic cylinder body feed device of a thin-wall drill welding machine frame, which belongs to the technical field of machine tools. The problem that an existing automaticfeeding and discharging device of a thin-wall drill welding machine is suitable for a small diameter range of thin-wall drills is solved. The automatic cylinder body feed device includes a turntable and a holding plate, a plurality of first receding notches are formed in the outer edge of the turntable, and a plurality of groups of cylinder body clamping assemblies are fixed on the turntable; thefirst receding notches are distributed in the circumferential direction around a shaft axis, and the groups of cylinder body clamping assemblies are arranged in one-to-one correspondence with the first receding notches; and the holding plate is located under the turntable, a positioning sleeve is fixed to the holding plate, and the holding plate and a machine frame body are connected by a third driving mechanism capable of moving the holding plate in lifting and lowering modes. According to the automatic cylinder body feed device of the thin-wall drill welding machine frame, the horizontal position of a thin-walled drill cylinder body is positioned through the positioning sleeve, and both a turntable thin-wall drill and the holding plate can determine the height of the thin-walled drill cylinder body; and thereby the consistency of the installation positions of cylinder bodies of different diameters is ensured.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and relates to a thin-wall drill welding machine, in particular to an automatic supply device for a cylinder body of a thin-wall drill welding machine frame. Background technique [0002] Thin-wall drill welding frame is a special equipment for positioning cylinder and cutter head when welding thin-wall drill. The inventor has proposed many relevant documents about thin-wall drill welding, a cutter head clamping and positioning device and a thin-wall substrate welding device (application number 200820038094.1), which are used to clamp and position the cutter head and adjust the position of the cutter head so that the cutter head and the barrel The body is right. A barrel positioning device in a thin-wall drilling and welding machine (application number 201010173633.4), which is used to clamp and position the barrel and improve the consistency of the clamping state of the barrel. The thin-...

Problems solved by technology

There are some weak points in this technical scheme, 1, the diameter of thin-walled drill is 28mm-350mm, and the cylinder bottom size of small-diameter thin-walled drill is greater than or equal to the diameter of top, the diameter of the cylinder top of large-diameter thin-walled drill It will be larger than the bottom size, that is, the small-diameter thin-walled drill cannot be placed on the table, or the small-diameter thin-walled drill cylinder placed on the table is not conducive to automatic pick-and-place, so there is a problem of poor versatility ; 2. The workpiece placed on the platen is usually positioned through the side of the positioning slot. Because there are many models of thin-walled drills, the number of positioning plates with positioning slots installed on the platen is also large. This not only Increases manufacturing costs and affects ease of use
