DEVICE FOR VERY FINE DISPLAMENET ESPECIALLY OF MACHINE-TOOL'S WORK TABLE

摘要

The device consists of a guide body (5) with the shape of an oblique prism placed on the table (1). The guide body (1) is connected with a regulating bolt and is roller-bearing mounted both on the first pulleys arranged in the groove (7) of the body (5) and on the second pulleys (9), whose pins (12) are connected with the levers (14), which are further swivelling and connected with the feed stop pieces (4) being pivoted between the third pulleys (10), while the pins (11) of the first pulleys (8) and the pins (13) of the third pulleys (10) are firmly connected with the work table (1). The stop pieces (4) are arranged near the ends of the table (1) against the gauge stops (2), which are placed on the bed (3) of the table. The table (1) is firmly connected with a nut (15) of the nodular helical gear, whose bolt is by means of the gears in an alternative connection with the hydraulic motor (21) of the quick feed and with the hydraulic cylinder (25) of the fine feed.<IMAGE>
