DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary tool table for a lathe, and more particularly, to an auxiliary tool table for a lathe capable of easily and easily performing a center operation, a drilling operation, a tapping operation and a boring operation on a workpiece.

[0002]

2. Description of the Related Art As shown in FIG. 1, a lathe generally comprises a headstock 10, a bed 20, a carriage 30, and a tailstock 4.
0 and accessory devices. The headstock 10 includes a main spindle that rotates by receiving the power of an electric motor, and a chuck 11 that fixes a workpiece to a thread portion of the main spindle. The number of revolutions of the main spindle that rotates the workpiece is adjusted by a transmission gear device. The bed 20 supports the headstock 10, the carriage 30, and the tailstock 40, and the carriage 30 moves along the guide surface of the bed. The carriage 30 is composed of a carriage transfer handle 30a, a saddle 31, a lateral transfer table 32, a compound tool table 33, and the like.
The carriage 30 is moved along the bed 20 by the carriage transfer handle 30a. The tailstock 40 is used to support a workpiece by fitting a center to the spindle, and a drilling operation can be performed by using a drill instead of the center.

[0003] The lathe thus constructed can perform various cutting operations. In particular, in the lathe work, center work, hole processing and thread cutting work are performed after the worker moves the tailstock 40 located on one side of the lathe to the work position,
After the center drill (not shown) is mounted on the tailstock 40, the center base drill for fixing the work using the lock lever of the tailstock 40 and searching for the exact center of the workpiece is performed. . After the center drill work, tailstock 4
After the center drill is removed by retracting the center drill, a drill having a standard to be machined is further mounted on the tailstock 40, and then fixed using a lock lever. Perform drilling work on the workpiece.
In order to thread the hole formed in this manner, it is necessary to remove the drill from the tailstock 40 and then thread the hole instead of the tap.

However, in order to perform a center work on a workpiece and make a tap by making a hole as described above, the operator must repeatedly move the heavy tailstock to the work position, In addition, each work process involves the inconvenience of having to change tools with the tailstock, and therefore, there is a problem that the work efficiency is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. As shown in FIG. 3, the lathe assist tool table 100 of the present invention includes a support bracket 110 fixedly installed on a lateral transfer table 32 of the lathe.
A rotating plate 120 coupled to the lock handle 130 so as to be rotatable discontinuously with respect to the support bracket 110;
A plurality of tool connecting arms 121a, 121b, 121c formed extending from the rotary plate, and tool connecting means 122a, 12 provided in each of the tool connecting arms.
2b and 122c.

Preferably, the tool connecting means includes a drill chuck 122a, a center drill holder 122b,
And tap chuck or boring bar holder 122
The center work, drilling, tapping work and boring work can be performed efficiently.

Referring to FIG. 4 and FIG. 6, the support bracket 110 has a hole 111 formed on a lower side thereof for fixing the horizontal transfer table 32 of a lathe with bolts, and a rotating plate 120 on the upper side. Since the shaft 131 and the lock handle 130 are provided so that the rotating plate 120 can be rotated or fixed, an operator operates the lock handle 130 to rotate the rotating plate 120 or fix the rotating plate 120. be able to.

The support bracket 110 has an insertion hole into which a stopper 123 on which a spring S is resiliently inserted is inserted so that the rotating plate 120 can be rotated discontinuously in one direction. 112 are formed, and the spring S and the stopper 123 are inserted. Referring to FIGS. 6 and 7,
The rotating plate 120 facing the insertion hole 112 of the support bracket 110 has a guide slot 124 inclined along an arc shape corresponding to the rotation radius of the spring S and the stopper 123, and a stopper such that the stopper 123 is seated. A stop claw 125 is formed. Preferably, the rotating plate 1
The position of the stopper 123 formed on the center 20 of the lathe chuck 11 is positioned at the center of the lathe chuck 11.
The stopper stop claw 125 is formed at a position where the center of 22c coincides. When the rotating plate 120 and the support bracket 110 are configured as described above, the operator rotates the lock handle 130 to operate the rotating plate 120 so that the rotating plate 120 can be rotated. When the stopper 123 having elasticity in the axial direction rotates along the guide slot 124 and is applied to the stopper stop claw 125, that is, at a position where the center of the tool coupling means coincides with the center of the chuck 11 of the lathe. Is seated on the stopper stop claw 125, the rotation plate 120 stops rotating discontinuously, and the operator can select a desired work tool and perform work.

The working process using the auxiliary tool table of the present invention thus configured is as follows. First, the auxiliary tool table 100 of the present invention is fixedly installed on the lateral transfer table 32 such that when the lateral transfer table 32 of the lathe moves to the leftmost side, the center of the tool coupling means coincides with the center of the chuck 11, Next, the workpiece to be machined is fixed to a chuck 11 of a lathe, and a center drill (not shown) and a drill and tap or boring bar of a size to be machined are respectively provided with a center drill holder, a drill chuck and a tap chuck. Or fix it to a boring bar holder. next,
The center is displayed on the workpiece using a center drill fixed to the center drill holder 122b. When the center drill operation is completed, the operator rotates the rotary plate 120 to position the drill chuck 122a at the center of the lathe chuck 11. After that, a drilling operation is performed using a drill. Then
When a tap is to be made, the rotary plate 120 is rotated to position the tap chuck 122c at the center of the lathe chuck 11, and then a tapping operation is performed. When a boring operation is performed, a tap chuck is attached to the rotary plate tool coupling arm. Instead of using a boring bar holder to carry out boring.

[0013]

As described above, the auxiliary tool table of the present invention is installed on the lateral transfer table of a lathe to perform center work, drilling,
Tapping operation and boring operation can be performed more efficiently. Unlike the conventional manual operation using only the tailstock, the automatic and manual operation using the automatic and manual transfer functions of the carriage is available. Therefore, not only the quality of the processed product can be improved, but also the working time can be shortened and the working efficiency can be improved.
