Problems solved by technology

The current drilling method (especially the flange holes of valves, which are generally equidistant) is to draw the hole positions on the workpiece with a template with pre-designed hole positions, and then place the workpiece on the drilling machine On the working table or the drill bit goes through the template to drill on the product, and finally move the rocker arm of the radial drilling machine to align with the hole position to drill. Every time a hole is drilled, it has to be moved once and then re-aligned again. The working efficiency is slow. And the positioning error is large

Embodiment 1

[0018] like figure 1 , figure 2 , image 3 A turntable is shown, which consists of a base 1, a positioning device arranged on the side of the base 1, an indexing body 2 arranged on the base 1, a thrust bearing 41 arranged on the upper middle of the indexing body 2, and a mandrel 4 arranged on the base 1 It is composed of a rotating tray 3 arranged on the indexing body 2. The pallet 3 above the indexing body 2 can be equipped with a three-jaw chuck or product positioning.

[0019] The periphery of indexing body 2 bottoms is provided with 2 layers of positioning holes 5, and the number of holes 5 of each layer of positioning holes 5 is all different, which can be determined according to the number of holes to be drilled. This positioning hole 5 is a trapezoidal hole, which can play a role in dividing. blocking effect. The upper edge of the indexing body 2 is larger than the upper edge of the base 1, and there is a groove 21 under the upper part of the indexing body 2 corres...

Abstract

The invention discloses an accurately-positioned rotating disc for a rocker arm drill press, which is particularly suitable for the special use of a flange hole of a drill valve or a flange piece hole and other products. The accurately-positioned rotating disc comprises a base, a positioning device which is arranged on the side of the base, an inner middle part of an index body which is arranged on the base and a base mandrel, wherein the index body can be matched with a rotating tray and a spiral chuck. The periphery on the lower part of the index body is provided with at least two layers of positioning holes, and the number of each layer of the positioning holes are different. The lower side of the upper part of the index body is provided with a groove which is corresponding to a convex ring arranged on the base, and the upper part of the index body is locked with the rotating tray through a screw nail. The mandrel is provided with a thrust bearing, and the base is provided with at least two hollow projections which are corresponding to the positioning holes on the index body, wherein springs are arranged in the hollow projections, and positioning bolts pass through the hollow projections and are inserted in the positioning holes. The inner bottom surface of the base is particularly provided with a circle of steel balls. The accurately-positioned rotating disc has the characteristics of reasonable structure, accurate positioning and high speed, and has light weight and large carrier capacity.

Description

technical field [0001] The invention relates to a turntable, in particular to a special turntable for drilling valve flange holes and other products on a radial drilling machine. Background technique [0002] The radial drilling machine is a machine tool with a wide range of uses. It can be used for drilling, reaming, reaming and tapping holes for small and medium-sized parts. It mainly includes a worktable, a spindle, and a column on one side of the workbench. , a rocker arm that can be raised and lowered along the column is arranged on the column, and a spindle case that can slide laterally along the rocker arm is arranged on the rocker arm. The current drilling method (especially the flange holes of valves, which are generally equidistant) is to first draw the hole positions on the workpiece with a template with pre-designed hole positions, and then place the workpiece on the drilling machine On the working table or the drill bit goes through the template to drill on the...
