ドリル作業等における連続する長い切屑を短尺化
する自動切屑処理装置などとすることができる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for rotating a rotating shaft and reciprocating an operating shaft that is integral with the rotating shaft or separate from the rotating shaft. By applying this principle, it can be used as an operating source for a fine reciprocating device for a grinding wheel in super finishing in machining, or as an automatic chip processing device that shortens continuous long chips in turning, drilling, etc.
以下に、自動切屑処理装置の例をとつて説明す
る。作業の妨碍となる連続する長い切屑を自動的
に処理することの必要性は周知である。 An example of an automatic chip disposal device will be explained below. The need to automatically handle long continuous chips that interfere with operations is well known.

具後退に与えられる作動時間は数十分の一秒など
の短時間である。 The method of these devices incorporates the operation of retracting the cutting tool a short distance, approximately the thickness of the chip, at regular intervals during the mutual rotation of the workpiece and the cutting tool, while the cutting tool moves forward at a constant speed due to machine feed. ,result,
Each time the cutting tool moves forward in cutting a certain distance, it retreats and interrupts the cutting, and the continuous chips are divided into groups of chips corresponding to the cutting length between the retreating steps of the cutting tool. The length of the chip to be separated is approximated by dividing the cutting speed by the number of times the cutting tool retracts per unit time, and the retracting distance of the cutting tool is calculated by dividing the cutting speed by the number of times the cutting tool retreats per unit time.
It is determined in terms of the feed distance per revolution. In order to shorten the number of chips to be separated, the number of retractions of the cutting tool should be increased per unit time in accordance with the cutting speed. In practical applications, there are cases where the cutting tool is retracted more than 300 times per minute when cutting steel materials, and in such cases, the operating time given to retract the cutting tool is a short time, such as several tenths of a second.

後退である。 When the rotating shaft rotates in this manner, the bearing ring rotates together with the collar 11 that is in surface contact with the roller 13.
is a spring 1 between the rolling surface of the bearing ring and the cam surface of the cam ring.
It is sandwiched under the tension of 6, and rotates and revolves together with the retainer without slipping. Due to this revolution, the rollers 13 move to the low points a, b, and c of the cam surface.
To reach heights A, B, and C, the rotating shaft is pushed down along a spiral staircase-like slope along with a series of working parts such as bearing rings and sliding bodies, and the cam surfaces A, B, and
From C to a, b, and c, the spring tension causes the robot to descend from a high place to a low place in a short time. This descent of the roller from a high place to a low place is a retreat with respect to the forward direction of the rotating shaft.

In this structure, the number of reciprocating movements of the rotary shaft, that is, the number of retreats, is 1.5 times the number of rotations of the rotary shaft, but it is possible to change the number of rollers and the configuration of the cam surface as desired depending on the general purpose. It is.

They are mounted concentrically, and the drive shaft and rotary shaft are connected inside the mounting tube using a method such as a slide key that enables short distance reciprocation in the axial direction of the rotary shaft, and a drill chuck 2 is attached to the operating shaft end of the rotary shaft.

By repeatedly moving forward and backward, the chips are shortened and discharged. That is, it is an automatic chip disposal device for drilling work.

To explain using the example shown in FIG. 5, an angular ball bearing 31 is replaced in the position of the thrust bearing 17 installed between the rotating shaft and the sliding body in FIG.
A rotating shaft is fitted into the inner diameter and brought into contact with the collar 11, and the outer ring is held by the sliding body 4.

構成は第１図の通りとする。 The retainer of the angular ball bearing 31 is extended upward to form a reduction frame 32, a radial bearing 34 is provided between the inner diameter portion of the frame 32 and the rotating shaft to enable mutual rotation of the two, and a thrust bearing 33 is installed on the upper surface of the collar 11. The thrust force acting between the rotary shaft and the reduction frame is rotatably supported. The cam mechanism is installed between the upper end surface of the reduction frame and the inner upper surface 10 of the cylindrical body. The other configuration is as shown in Figure 1.

ギユラ形ころがり軸受であれば、その形式に制限
はない。 Now, when the rotating shaft rotates, the reduction frame 32 rotates at the same rotation speed as the retainer of the angular ball bearing.
Since the rotation is the revolution of the ball, it is a rotation speed that is slower than the rotation speed of the rotating shaft, and is the rotation speed of the bearing ring of the cam mechanism. Since the reduction frame can be rotated independently of the rotating shaft by the radial bearing 34 and the thrust bearing 33, it can be rotated at a rotation speed different from that of the rotating shaft. The other operations are the same as in the case of FIG. As a result, the number of retraction operations relative to the rotational speed of the drill is smaller than in the case of FIG. 1, and the chips to be separated are longer. In commercially available angular ball bearings, the revolution speed of the balls is approximately 1/2.5. The type of bearing used for this purpose is not limited as long as it is an angular roller bearing that supports rotation and thrust.

The operating shaft is fitted into the cylindrical body, and is prevented from rotating by a slide key 43 or the like so as not to rotate during reciprocating movement in the left and right direction. A necessary cutting tool is attached to the cutting tool mounting portion at the left end of the operating shaft, and a motor 41 for driving and rotating the rotary shaft is attached to the right end surface of the cylindrical body, and the motor 41 is connected to the shaft.

The cutting operation is carried out by repeating this process alternately, and each time the cutting tool retreats, the chips are separated and shortened. That is, this device is an automatic chip disposal device in which the operating shaft does not rotate.
