Embodiment Construction

[0023] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 and figure 2 As shown, it is the drilling and reaming sleeve template used in the present invention, including template 1. In this embodiment, the processed workpiece is a stacker-reclaimer rotary disk with a diameter of 7.5m, and the radial drilling machine is used to pass the indexing of the drilling and reaming sleeve template on the rotary disk. 248 sets of holes with a diameter of Φ50mm are processed on the end surface of the circumference. The shape of the template and the upper holes are completed by laser cutting. The template is arc-shaped, and the diameter of the outer arc 1-2 is equal to the diameter of the outermost circle of the turntable , the diameter of the inner arc 1-1 of the arc template is equal to the diameter of the inner circle of the walking track surface 4-1 on the rotary disk 4, which is conven...

Abstract

The invention discloses a method for processing large workpiece boring hole by using a drilling machine, comprising the following steps: 1. placing a processing workpiece on a supporting component, centering and fixing the processing workpiece, and reserving drilling machine base storing position below the processing workpiece; 2. lining out a hole line on the processing workpiece according to the position of a boring hole to be processed; 3. manufacturing a template according to the boring hole to be processed, and installing a drilling and reaming sheath on the template so as to manufacture a drilling and reaming sheath template; 4. fixing the drilling and reaming sheath template with the processing workpiece by a fixing component, and putting the drilling machine at a proper position, and then drilling and reaming the hole at different times. By using the method to process end face holes of large workpieces, the processing cost is low, the speed is high and the precision is high. For enterprises without large-sized boring machines, the method can be utilized to extend the business scope of general machine processing enterprises, reduce the cost and increase the economic benefits of the enterprises.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a method for mechanically processing large workpiece bores by using a drilling machine. Background technique [0002] At present, the equipment required for boring holes on the end face of large workpieces is usually a large boring machine, but for machining companies with general machining capabilities, there is no large boring machine. : 248 groups of Φ50mm holes with a distance of 168mm between the upper and lower crotch), due to the limitation of the type and capacity of the enterprise's equipment, it is often necessary to seek an enterprise with processing capabilities to carry out outsourcing processing, and the processing and transportation costs that occur are very high, increasing the cost of the enterprise The production cost has brought great difficulties and losses to the production and operation of the enterprise. Contents of the invention [0003] The technical p...
