Embodiment

[0017] Example: Circular workpieces are usually divided into two types: circular workpieces with inner holes and circular workpieces without inner holes. The present invention is applied to a circular workpiece with an inner hole such as a flange for drilling and positioning such as figure 1 , figure 2 Shown; The present invention is applied to a circular workpiece without inner hole such as pipeline end cover drilling processing positioning such as image 3 , Figure 4 shown. Such as Figure 1 to Figure 4 As shown, the bottom plate 1 is made of 30mm~40mm thick steel plate. According to the size and thickness of the outer diameter of the bearing 4, a circular groove is milled in the middle of the steel plate, and two-thirds of the outer diameter of the bearing 4 is clamped on the circle of the bottom plate 1. In the shaped groove, due to the tight fit, there will be no relative rotation. There is a circular boss in the middle of the upper and lower sides of the turntab...

Abstract

The invention discloses a circumferential drilling hole positioning device for a round workpiece. The circumferential drilling hole positioning device comprises a bottom plate, a positioning mechanism, a turntable, a bearing, a pressing mechanism and a support ring, wherein the bearing is arranged in a round groove of the bottom plate in a clamping way, the turntable is annularly clamped and arranged in the bearing, the pressing mechanism is arranged on the turntable, the support ring is arranged under the turntable, the positioning mechanism is arranged on the bottom plate, and the front end of a positioning rod of the positioning mechanism is in butt joint with equant V-shaped notches formed in the outer edge of the turntable. The circumferential drilling hole positioning device has the advantages that a drilling hole can be positioned through directly selecting the V-shaped notch corresponding to a bisectrix marked on the turntable, the line drawing or template manufacturing is not needed, the work efficiency is high, the processing cost is reduced, the universality is good, and the product processing precision is high.

Description

technical field [0001] The invention relates to an auxiliary device for drilling a mechanical part, in particular to a peripheral drilling positioning device for a circular workpiece. Background technique [0002] For the processing of the equally divided holes distributed on the circumference of the circular workpiece, the scribing or the 15mm-20mm thick steel plate is used to make the template, and then the drilling is positioned according to the scribing or the template. Scribing and positioning drilling requires marking and positioning for each specification of the workpiece, which is inefficient, and the scoring and positioning drilling accuracy is not high. Set of template positioning drilling means that a template can only correspond to one type of workpiece, and its versatility is not good. For workpieces of different specifications, templates must be made, which increases the manufacturing cost and workload of circular workpiece drilling. Contents of the invention...
