Abstract

PROBLEM TO BE SOLVED: To provide a tapping device to solve such problems that an object to be tapped can not be tapped if it is larger than an interval between a tap and a worktable, in a normal vertical tapping machine, and if the workpiece is small and if the peripheral part of its tapping part is bent after it is tapped because of a drawing process, an assembling work is not carried out well and many defectives appears in succession because the pitch of a screw thread shifts. SOLUTION: This horizontal moving tapping machine is composed of a driving part, a spindle pulley, a spindle gear and a tap chuck, and the tap moves horizontally on it. It has the feature that the worktable detachable to the horizontally moving front part of the tap and vertically ascendable and descendable is provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tapping machine processing in metal sheet metal work.

[0002]

2. Description of the Related Art Conventionally, as a tapping machine in which a tap is moved up and down (hereinafter referred to as a vertical type), Japanese Utility Model Publication No. Sho 51-30
237, JP-A-5-313718, JP-A-5-38623, and the like.

[0003]

In a general vertical tapping machine, if the tapping object is larger than the distance between the tap and the work table, the tapping operation cannot be performed. In addition, if the tapping product is small, tapping in the sheet metal processing process and then bending the periphery of the tapping part will cause the thread pitch to shift and the assembly work will not be good, and defective products will continue. There is a problem of doing.

An object of the present invention is to solve the above-mentioned problems. That is, it is an object of the present invention to provide a processing apparatus which can quickly and efficiently assemble a tapping process after performing a bending process on a product with a small workpiece and which contributes to a reduction in product cost.

[0005]

Means for achieving the above object are, as described in the claims, composed of a drive unit, a main shaft pulley, a main shaft gear and a tap chuck, and the tap moves horizontally. The horizontal tapping machine is characterized in that a worktable that can be attached to and detached from the front part of the tap and that can be moved up and down is provided.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of one embodiment of the present invention. FIG. 2 is a front view of FIG. 1 of the present invention. FIG. 3 is a representative drawing of the present invention, and is a side view of FIG. The embodiment will be described below in accordance with the operation procedure in FIG.

[0007] 1. Turn on the power. 2. From the transparent window 2 of the gear cover 1, the number of revolutions of the main shaft gear is confirmed. In the present invention, one transparent window 2 made of plastic or glass is provided at the center of the gear cover 1 so that the gear cover 1 is opened each time to check the pitch of the gear cover 1 as in a conventional machine. It has the effect that it is not necessary.

[0008] 3. Check the belt position corresponding to the main shaft gear rotation speed. 4. Attach tap 4 to tap chuck 3. 5. The number of manufactured products is adjusted by the counter 5.

6. The work 7 to be tapped is fixed on the worktable 6 with a vice or the like, and the handle 9 of the elevating shaft 8 of the worktable 6 is fixed.
The tapping position of the workpiece 7 and the height of the tap 4 are adjusted.

[0010] 7. Adjust the tapping depth of the workpiece 7. 8. An oil dropper 11 is fixed on the tap 4 from the oil snake 10 and the dropping speed is adjusted by a cock. 9. The foot switch 12 is depressed for tapping. 10. Check the number of counters with a buzzer. 11. When the power is turned off, the tapping work of the present invention is completed.

According to the present invention, the drive unit 1 is removed by removing the work table 6, which is a main component of the present invention, from the work table base 13.
4 as shown by the dotted arrow in FIG.
It can be used as a general vertical structure tapping machine as shown by. A similar function is also possible with a drilling machine.

Since the caster 15 is attached to the main body, it can be moved anywhere.

The setting of the spindle speed can be changed according to the material to be processed. For example,

[0014]

Since the present invention is configured as described above, it has the following effects. When a tapping process is performed after bending a small workpiece, an assembling operation is quick, efficient, and has an effect of reducing product cost.

[0015] The structure of the present invention can also be used for horizontal tapping.
It can be easily changed to normal vertical tapping. That is, there is an effect that it can be used in a horizontal type or a vertical type as required.
