Embodiment Construction

[0012] The present invention will be further described below according to accompanying drawing.

[0013] figure 1 The linkage compression multi-hole drilling tool shown is a structural schematic diagram when the workpiece is to be positioned and installed or the processed workpiece is to be taken. It includes a multi-axis drill chuck 1, a template 2, a guide rod 3, a base 4, a pad 5, a positioning Mandrel 6, pressure head 7, drill sleeve 8, small shaft 9, spring 10 and nut 11. Both sides of the base plate 4 at the bottom are respectively provided with vertical guide rods 3, and the middle part is provided with an upward positioning mandrel 6. The outer diameter of the positioning mandrel 6 is equal to the size of the inner hole of the workpiece, and the two are in clearance fit. Both sides of the positioning mandrel 6 are provided with spacers 5 of equal height, and the axis of the positioning mandrel 6 is perpendicular to the upper plane of the spacer 5 . The multi-axis dri...

Abstract

The invention discloses a linkage compressed type multihole drilling tool. The linkage compressed type multihole drilling tool comprises a multishaft drill chuck, a template, a guide rod, a base, a cushion block, a location core shaft, a compressing head, a drill bushing, a small shaft, a spring and a nut; a framework structure consists of a base and the guide rod; the location core shaft and the cushion block are arranged on the middle part of the template; the template is positioned below the multishaft drill chuck and spaced from the multishaft drill chuck in parallel; the spring is arranged between the multishaft drill chuck and the template; and the multishaft drill chuck and the template are connected through the small shaft and the nut to form a linkage mechanism capable of elastically moving along the axial direction of the guide rod. The compressing head on the bottom surface of the template is coaxially opposite to the location core shaft. During use, the template moves up and down with the multishaft drill chuck along the guide rod; when the compressing head is contacted with a workpiece, the template stops moving; the compressed spring compresses the workpiece with an elastic force; and a drilling head performs drilling and cutting under the protection and the guide of the drill bushing. After drilling and cutting, the multishaft drill chuck moves upward and the pressing head gets rid of the workpiece, so the machined workpiece can be taken out; and the operation is repeated to realize mass production. In the linkage compressed type multihole drilling tool, the auxiliary production working period is short and the production efficiency is high.

Description

technical field [0001] The invention relates to a drilling tool used in the machinery manufacturing industry, in particular, the invention relates to a drilling tool which is coupled with pressing and drilling under the condition of workpiece positioning. Background technique [0002] During batch drilling, drilling is usually carried out with the help of special positioning fixtures and drilling templates. After a piece of workpiece has been machined, it must be disassembled in reverse order, and then the workpiece to be processed is installed. Such repeated operations are a feature of the prior art. Obviously, the auxiliary production man-hours of the prior art are longer than the drilling man-hours, resulting in low production efficiency, which does not meet the requirements for mass production. Contents of the invention [0003] The present invention mainly aims at the deficiencies of the prior art, and proposes a linkage-type compaction multi-hole drilling tool. The ...
