Description

one

The invention relates to metal working.

The purpose of the invention is to increase the reliability of fastening the cutting plate due to the additional pressing of this plate to the movable element when securing the cutting plate by inserting an elastic element into the cutting tool located in the holder slot between the movable and the supporting elements.

Figure 1 shows the cutting tool, top view; figure 2 - section aa in Fig, 1; on fig.Z - section bb in figure 1; Ia figure 4 - the elastic element, the view in the plan.

The cutting tool consists of a holder 1, a movable element 2, a pin 3, a cutting plate 4, a support element 5, an elastic element 6 and a spring 7, the Holder 1 is provided with a socket, a supporting wall 8 and a protrusion 9. The movable element 2 is made flat, located in the slot the holder 1 and provided with a hole and two grooves, one of which is the protrusion of the support element 5 with a spring 7, and the other (S) - the protrusion 9 of the holder 1. 3 is cylindrical and located in the holes of the movable element 2 and the cutting plate 4. The cutting plate 4 is made triangular oh and located on the movable member 2 .. The support member 5 is provided with a wedge portion in contact with the support wall 8 of the holder 1 and the cutting plate 4 and the elastic member 6. The elastic member 6 is corrugated (undulating). In general, he may also have a friend.

curved shape, the spring 7 is made cylindrical helical, located in the hole of the protrusion of the support element

5i is designed to hold the last 5 on the holder in the absence of a cutting insert. The protrusion 9 and the groove 10 are located at an angle to the support wall 8. Elastic element

6 is located between the movable element 2 and the supporting element 5. The distance between the protrusion of the supporting element 3 and the supporting wall 8 ho is made equal to the height of the elastic element 6 h.

The clamping of the cutting plate 4 is carried out by pressing on the movable element 2 in the direction of the RE force. In this case, the cutting plate 4 and the support element 5 move

 right parallel to the support wall 8, and the movable element 2 with the pin 3 parallel to the protrusion 9. As a result, the cutting plate 4 and the elastic parts are wedged on the holder 1. When jammed, the height of the elastic element bhr decreases, due to which the supporting element 5 moves down and provides pressure the cutting plate 4 to the rolling element 30.

The unwinding of the cutting plate 4 is carried out by pressing on the movable element 2 in the direction opposite to the direction of the force Pj.

35 Assembling the cutting tool as follows. A pin 3 is placed on the movable element 2, a plate 4, a supporting element 5, an elastic element 6 and a spring 7i

40 Then, the movable element 2 with the indicated parts is inserted from the side into the holder 1.
