Abstract

The invention relates to instrument making and can be applied when adjusting and unilaterally fixing two parts together without their relative movement. The goal is to facilitate the assembly of the parts to be joined. The part 8 is symmetrically mounted along the axis of the joint relative to the part 10. Then the cam 1 is installed in the radial grooves on the screws 13 and 14, without turning it to the stop. Then screw the screw 13 until it stops, while the conical head of this screw rests on the conical grinding, moving the cam into the sample 9. This movement of the cam 1 occurs with sliding on the end face 15 of the sample 9 with contact between them around the circumference and ends with the abutment of the cam 1 into the surface 16 samples 9 with contacting between them also on a circle. When the cam 1 is located within the conical sample, the part 10 is wedged against the part 8. A wedge-shaped gap 17 is formed between the cam 1 and the end 7 of the radial groove. After jamming, the cam 1 is additionally secured with an additional screw 14 with a cylindrical head. For a more rigid fixation of the cam 1, a screw 14 is inserted between the screw 13 and the sample 9. The use of the invention makes it possible to adjust the alignment twice as fast due to the possibility of one-side fixation of the part from one of its ends. 2 Il.

Claims (1)

Claim A device for fixing parts, containing fixing elements evenly spaced around the gun with axial holes and end bevel sharpeners installed in the radial grooves of the base part with the possibility of interaction of their outer surfaces with an internal conical selection of the part to be attached, and screws with supporting conical installed in the holes of the fixing elements surfaces of the heads in contact with the end face conical sharpening of the corresponding locking element, characterized by we note that, in order to facilitate installation, it is equipped with additional screws installed in additional axial holes made in each fixing element above its end conical sharpening, while the fixing elements are made in the form of cams with end conical surfaces and are installed with the stop of one of these surfaces at the end of the inner conical selection of the joining part, which is offset in the axial direction relative to the plane of the ends of the radial 10 grooves, the outer diameter ulachkov and angle of the cone cams equal diameter and angle of the conical inner generatrix sample attachable parts.
