Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a balance holding device for a processing machine having a function capable of preventing saddles from being tilted by the weight of a head when saddles are fed from the base of the processing machine.

The processing machine shown in Fig. 1 is basically composed of a base, a saddle, a head, and a table. As shown in the figure, the saddle is transported back and forth from the base, and the head is vertically transported from the saddle.

Such a processing machine causes the saddle to hear the back of the bird due to the weight of the head when the saddle is moved away from the base.

This causes the parallelism of the birds to collapse, leading to the problem of machining errors.

Conventionally, a method has been used in which a pulley is provided at the rear portion of a bird to pull down the rear portion of the bird by weight, or the angles at which the birds are inclined are measured, and the values are taken into consideration.

However, in the former case, due to the weight load, the saddle is disadvantageously disturbed and the front of the saddle can be heard when the saddle is located at the rear of the base. In the latter case, There is a problem that the machining speed is slow because the condition is limited and the error is severe and the machining zero point must be checked from time to time. Both of them have a problem that the number of components is high and the cost is increased due to the complexity of the apparatus.

Patent No. 10-0454301.

The present invention has been developed in order to solve the problem of inclination of birds as mentioned in the background art, and in particular, it is intended to maintain the balance of birds in a simpler, simpler and more efficient manner than in the past.

In order to achieve the above-mentioned object, the present invention provides a method of mounting a roller on both sides of a rear portion of a saddle, mounting a rail in a cross shape on both sides of a rear portion of a base, I suggest.

According to the above-described means, even if the saddle moves away from the base, the rails on both sides of the base rear portion can be supported by the rollers on both sides of the saddle rear portion to prevent the rear portion of the saddle from being lifted. Therefore, the balance of the saddle can be easily, There is an effect.

Further, the leaf spring 226 for exerting the elastic force by the adjusting means has an effect that the elastic force is not changed even if it is used for a longer time than the coil spring, and can be held by a strong pressure.

Hereinafter, the present invention will be described in further detail as follows.

The present invention may also be configured such that the rail 20 is in a simple cross-linked form. That is, the rails 20 can be mounted parallel to the surface of the base A1 by a simple bracket-like mounting portion without the pivoting means of the pivoting portion 21, the height adjusting means of the adjusting portion 22, and the elastic means. However, when the rear end of the saddle A2 is lifted, the force of the rear end of the saddle A2 is not generated, and the rail 20 may be bent or the mounting portion may be torn from the base A1. This configuration is preferably applied to a machining machine having a very weak force to catch the rear end of the saddle A2.

The leaf spring 226 included in the present invention may be replaced with a coil spring. However, in the case of the coil spring, since the elastic force may be deteriorated by the repetitive force, it is preferable that the coil spring is applied to a machining machine in which the force to tilt the rear portion of the saddle A2 is very weak, as described above.

On the other hand, the application field of the present invention is not limited to a non-cutting machine. For example, it is applicable wherever the opposite side is linearly fed from one side and it is necessary to maintain parallelism with respect to the other side.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. And can be industrially usefully used.
