CS258037B1 - Portable Drilling Equipment - Google Patents

Abstract

The solution relates to the field of metalworking by cutting, in particular portable drilling machines for machining holes in hard-to-reach places for assembly and construction of large-sized sets. The solution is a drilling device equipped with a device for limiting the depth of drilling holes, formed by a spring-loaded rotating sleeve β of the pin and a spring-loaded fixator arranged inside the sleeve and holes for positioning the pins. The sleeve is kinematically connected to a nut, which is mounted with the possibility of displacement. The gear wheel braking device with a threaded hole is designed as an additional multi-rotor third clutch, mounted coaxially with the base. The sliding member is spring-loaded and connected to the additional clutch by means of an additional elastic element introduced into the device.

Claims (1)

OBJECT OF THE INVENTION A portable drilling device in which the housing and a spindle displacement device are disposed in the shape of a toothed gear disposed on the drive shaft coupled to the toothed openings to interlock with a groove and a threaded spindle. Possibility of cooperating with a toothed wheel by a threaded hole. A displacement member disposed in a hollow shaft by one end kinematically connected with a coupling by means of a resilient element and a second end with a pressing device in the form of a screw and a nut and a gear of the gear with a threaded bore. is provided with a device for limiting the depth of drilling * formed coaxially with the spindle (4) by the spring-loaded rotatable sleeve (28) provided with pins (35) kinematically coupled to the nut (22) which is disposed with displacement and within the sleeve (* 28) ) arranged the spring-loaded fixator (33) with the pin-dispensing apertures (35), wherein the gear-wheel braking device (3) with the threaded bore is formed by an additional multi-disc friction clutch (14) disposed coaxially with the base with the ability to interact with the gear with the threaded hole (3), the displacement member (17) is spring-loaded and coupled to the auxiliary coupling (14) by an additional spring element (16) introduced into the device. 258037
