Abstract

The invention relates to metalworking, in particular to machine tools for machining holes with ejector drills in parts of considerable length. The aim of the invention is to improve the quality of processing by stabilizing the conditions for the supply of coolant and removal of pulp from the drill when processing parts of considerable length. After fixing the part 2 on the table 1, the yoke 3 is moved along the table 1 and the spindle head 5 with the chuck 6 for the drill 7 along the traverse until the drill bit is set to a predetermined position. When moving the yoke 3 through the tank 9, placed along the table 1 and having a length overlapping the length of the table 1, the pump station tO moves, connected by a plate 11 with the yoke 3.

Description

The invention relates to meta-machining, namely to machine tools for machining holes with ejector drills in parts of considerable length.

The purpose of the invention is to improve the quality of processing by stabilizing the conditions for the supply of coolant (coolant) and removal of pulp from the drill when processing children of considerable length,

. The machine contains a table 1 for securing the tank 9 with coolant from getting lazy to work on the parts 2, foreign substances. A branch pipe 15 is supported on the table 1 with the possibility of traverse 3 along it, mounted on the traverse 3 with the possibility of moving along it along the guides 4 the spindle head 5 with the cartridge 6 for the ejector drill 7 and the conductor 8, along the table 1 there is a tank 9 for the coolant the length of the table 1 is selected based on the condition of overlapping of the length of the table 1. In addition, the machine contains a pumping station 10, rigidly connected through the plate 11 to the cross member 3 and mounted on the tank 9 with the possibility of moving it through the wheels 12, the chip conveyor 13 placedbetween the table 1 and the tank 9, the pipes 14 and 15, designed to supply coolant from the pump station 10 to the spindle head 5 and from the tank 9 to the collecting station 10, and the pipe 16 to discharge the pulp with chips to the conveyor 13. On the tank 9 there is a seal 17 nipple 15 „

Claims (1)

Invention Formula A machine for machining holes in 25 parts with ejector drills, containing a table for securing workpieces, placed on the table with the possibility of moving along it to the traverse, was set up on the traverse of the spindle head, coolant pump (Lubricating fluid) tank a coolant station from the tank to the headstock and a chip conveyor that is different 35 processing by stabilizing the conditions of coolant supply and removing the pulp from the drill when machining parts of significant length, the pump station is installed on the tank with the possibility of reciprocating movement along it and rigidly connected to the crosshead, the tank is located along the table and its length is selected of condition The machine works as follows. After securing the part 2 on the table 1 by moving the yoke 3 along the table 1 and the spindle head 5 along the path of 45 the length of the table, and the transport Versions 3 set drill 7 in position. At the same time pump processing due to the stabilization of the conditions for coolant supply and removal of pulp from the drill when processing parts of considerable length, the pumping station is installed on the tank with the possibility of reciprocating movement along it and rigidly connected with the cross-beam, the tank is located along the table and length selected from condition grated chips placed between the tank and the table. station 10 moves along the table 1 on wheels 2, since in this case the length and shape of the nozzles 14-16 does not depend on the location of the pump the station, the length and shape of the nozzles remain unchanged at whatever point relative to table 1 the yoke 3 moves, and the conditions for the supply of coolant to spindle head 5 remain stable. Since the length of the tank is equal to or greater than the length of table 1, the pump station 10 at any point interacts with the tank 9. Seal 17 of the nozzle 15 bakes stable chip discharge and also does not change the total resistance coolant supply protects tank 9 with coolant from ingress of foreign matter. Pipe 15 obes  protects tank 9 with coolant from ingress of foreign matter. Pipe 15 obes Invention Formula A machine for machining holes in 25 parts with ejector drills, containing a table for securing workpieces, placed on the table with the possibility of moving along it to the traverse, was set up on the traverse of the spindle head, coolant pump (Lubricating fluid) tank a coolant station from the tank to the headstock and a chip conveyor that is different  protects tank 9 with coolant from ingress of foreign matter. Pipe 15 obes 35 40 45 cover the length of the table, and transpor processing by stabilizing the conditions of coolant supply and removing the pulp from the drill when machining parts of significant length, the pump station is installed on the tank with the possibility of reciprocating movement along it and rigidly connected to the crosshead, the tank is located along the table and its length is selected of condition overlap the length of the table, and transport grated chips placed between the tank and the table.
