MACHINE FOR BEARING SHELL GROOVES DRILLING

摘要

Usage: machine tools, particularly boring machines for grooving inserts of the bearings. SUMMARY OF THE INVENTION: Tool machine head includes a housing 2, a spindle 3 and incisal mandrel 6. At one end of the spindle 3 is fastened a pulley 4 coupled to the motor, and the other - the faceplate 5, a guide mounted yuschih.koto- swarm Reztsova mandrel 6. The spindle 3, an axial hole. clip and supplying inserts mechanism includes a base member 18c mounting seat 23 for the insert 17, the actuator 22, a support 30, made in the form of two parallel strips, the stop 31, kronsh16 theine 27 with a bevel 29, rack 35 and power cylinder 38 with the clamping device. The focus 31 is formed as a wide strap with turned down at right angles and ends spring-loaded relative to the frame 1 by a spring 33. The mechanism disables the cutter radial feed rod 7 .; mounted in the axial bore of the spindle 3 and the two-armed lever 12. At one end of the rod 7 is mounted on bearing sleeve 10, is pivotally associated with the lever 12 and at the other end of the chamfer 8 is formed, cooperating with the bevel 9 of the cutting mandrel 6. After the treated liner 17 in the socket 23 and clamping will be effected displacement of the base member 18 to accommodate the cutting insert 17 over the mandrel 6. at this point, the bracket 27, a bevel 29 acts on the roller 16 of the lever 12, the latter is rotated and moves the rod 7, which impacts on the bevel 8 bevel 9, the cutting mandrel 6 moves it in the radial direction of the cutter vreza- performed to a predetermined depth. Upon further movement of the base member 18 manufactured by the axial feed of the liner 17 and boring groove width. 4 yl. 38 f 27 / E 00 with w ate
