Description

[Detailed description of the invention] The present invention relates to a working table for a drilling machine, in which the working table for a drilling machine is formed into a prismatic body with a plurality of surfaces, and the axis perpendicular to the guide post of the drilling machine body is the rotation axis. It has a rotatable structure and is designed to greatly improve the work efficiency of drilling machines.

Conventional drilling machines require a single work table to drill holes in parts or products of various shapes. To do this, a variety of jigs and tools that can be used for multiple purposes are required.If the workpiece is of the same shape, one type of jig or tool can handle the problem, but when drilling irregularly shaped workpieces regardless of the number of holes, has the following drawbacks: In other words, it is necessary to select the necessary jigs and tools according to the workpiece, set them on the work table, and then return them to the regular position from the table after use, which must be repeated two or three times, resulting in a decrease in efficiency. It also takes a lot of man-hours. Furthermore, when a general vise is used as a tool attached to a drilling machine, it is mainly used for fixing flat workpieces, and cannot be used for many purposes. Furthermore, frequent replacement of jigs and tools on the limited table board has drawbacks such as lowering work efficiency and increasing the degree of danger.

This invention solves the conventional problems as mentioned above,
In addition, the work efficiency of the drilling machine has been greatly improved, making it possible to drill holes in various processed products safely and quickly.

Next, a detailed explanation will be given based on the drawings.

In Figure 1, the drilling machine has guide post 1
A work table board 3 is provided via a guide bush 2 that slides up and down along the same direction, and further includes a hole drill part 4 and a fixing device 5 for fixing the work table board 3 in a fixed state. The fixing device 5 appropriately fixes the work table board 3 via a wire 7 supported by a bracket 7' by stepping on a foot pedal 6. To explain the working table machine 3 of the present invention in detail, as shown in Fig. 2, a guide bush 2 is fitted to the guide post 1 of the drilling machine so that it can slide up and down, and a step is attached to the guide bush 2 by bolts and nuts. A fixed platen 8 is fixed. A flanged rotating body 10 is rotatably supported on the central protrusion 8' of the stepped fixed disc 8 via a bearing 9.
A spacer 17 is interposed on the flange part 10' of the flanged rotating body 10 to make it flush, and the rotary disk 11 is fixed with bolts and nuts.
0, a table support plate 12 is fixed with bolts and nuts, and a triangular prism-shaped work table board is fixed to this table support plate 12 with bolts and nuts 18. Although the work table board 3 in the illustrated example has a triangular prism shape, it goes without saying that it may also have a quadrangular prism shape. In addition, the code|symbol 13 is a handle for rotation.

As shown in FIG. 3, the rotary disk 11 is provided with a recessed portion 14 at a location corresponding to each work surface of the work table 3 on its circumference, and is fixed to the recessed portion 14. A locking pin 15 of the device 5 is retractably engaged. This lock pin 15 is provided at the tip of the wire 7, and is always pressed toward the recessed portion 14 by a spring 16. The fixing device 5 is fixed to the guide bush 2 by suitable means.

Next, to explain the action, each work plate surface 3 ₁ , 3 of the work table board 3 is
₂ and ₃ , each of the jigs and tools shown as A, B, and C in FIG. 4 are fixed in advance. When working with the necessary tools, step on the foot pedal 6, and the lock pin 15 at the tip of the wire 7 is released.
is caused to escape from the recessed notch 14 against the force of the spring 16.
As a result, the rotary disk 11 of the work table board 3 becomes free, so the work table board 3 is rotated by the rotation handle 13, the necessary jigs and tools are brought directly under the hole drill part 4, and the foot pedal 6 is released. , the lock pin 15 enters the recessed part 14, and the work table board 3 is automatically fixed.

In this way, the present invention rotatably supports a work table with multiple work surfaces, and can fix the required surface of the work table with a single touch operation.This improves work efficiency and improves safety. ,
It allows you to work quickly.

Claims (1)

[Scope of utility model registration request] The work table board is a multi-sided prismatic body, and each face of the prism is used as a work board surface, and each work board surface is rotated about an axis orthogonal to the guide post as the rotation axis so that each work board surface can be selectively fixed directly below the drill part of the drilling machine. Drilling machine work table machine that can be attached to the drilling machine main body.
