Abstract

The utility model discloses a radial feeding device of a boring mill, belonging to the technical field of boring mills. A radial transmission case is fixedly arranged on a gear box; a motor is arranged on one side of the radial transmission case; a gear on the motor is connected with a gear I on a shaft of a worm gear; a shaft II is arranged in a worm gear shaft hole in the worm gear; a gear VII and a gear VI are arranged on the shaft II; an electromagnetic clutch is arranged at each of the side ends of the gear VI and the gear VII; a shaft I is arranged on the parallel side of the shaft II; a gear II, a gear III and a gear IV are arranged on the shaft I; the gear II is meshed with the gear VII, the gear III is meshed with the gear VI, and the gear IV is meshed with a gear V; a shaft III penetrates through the gear box to be arranged in a boring tool rod; a screw is arranged at the other end of the shaft III and is meshed with a screw sleeve; an inclined-tooth plate is arranged on the other end of the screw sleeve and is in sliding fit with inclined teeth on a tool rest; a tool is arranged at the front end of the tool rest so as to lead the tool to be fed in the radial direction rapidly; and a transmission part passes by a spindle and the interior of a boring rod to be in transmission with a boring head. For the radial feeding device, the structure is compact, the transmission is stable, and the rigidity is good.

Description

The boring machine radial feeding device

Technical field

the utility model relates to a kind of boring machine radial feeding device, belongs to the boring machine technical field.

Background technology

are present, and the radial feed of boring machine apparatus processing cutter generally adopts cantilevered, and the drive mechanism mode is that AC servomotor drives, ball-screw and a pair of bevel gear transmission, and complex structure, cost is high.

Summary of the invention

in order to overcome above-mentioned technical deficiency, the utility model provides a kind of boring machine radial feeding device, and this boring machine radial feeding device can not only move to assigned address with cutter accurately, and machining accuracy rational in infrastructure is high.

the utility model solves the technical scheme that its technical problem adopted: the boring machine radial feeding device is made up of the helical teeth panel assembly in radially transmission case and the boring bar, and radially transmission case fixedly is positioned on the gearbox, and radially transmission case one side is equipped with motor; Gear on the motor connects the gear one on the worm and gear axle; Be equipped with electromagnetic clutch on the worm gear on the worm and gear, be equipped with two in the worm gear axis hole on the worm and gear, be equipped with gear seven, gear six on two; The side of gear seven, gear six is respectively equipped with electromagnetic clutch; A parallel side of two is provided with one, and one is provided with gear two, gear three, gear four, gear two and gear seven engagements; Gear three and gear six engagements, gear four meshes with gear five on three; Three are passed gearbox and insert in the boring cutter bar, and three the other end is provided with leading screw and silk braid engagement, and the helical teeth that the silk braid other end is provided with on helical teeth plate and the knife rest is slidingly matched, and the knife rest front end is provided with cutter.

The beneficial effect of the utility model is: the work flexibility and reliability, and easy to operate, can make the quick radial feed of cutter; Drive disk assembly is through main shaft and boring bar is inner and the boring head transmission, compact conformation, stable drive; Rigidity is good, and the range of work is big, and machining accuracy is high.

Description of drawings

Fig. 1 is the utility model boring machine radial feeding device structure chart.

Among figure 1, motor, 2, gear one, 3, worm and gear, 4, gear two, 5, one; 6, two, 7, gear three, 8, gear four, 9, three, 10, gearbox; 11, silk braid, 12, leading screw, 13, cutter, 14, knife rest, 15, the helical teeth plate; 16, boring cutter bar, 17, gear five, 18, gear six, 19, gear seven.

The specific embodiment

are as shown in Figure 1, and the boring machine radial feeding device is made up of the helical teeth panel assembly in radially transmission case and the boring bar, and radially transmission case fixedly is positioned on the gearbox 10; Radially transmission case one side is equipped with motor 1, and gear on the motor 1 connects the gear 1 on 3 of the worm and gears, is equipped with electromagnetic clutch on the worm gear on the worm and gear 3; Be equipped with two 6 in the worm gear axis hole on the worm and gear 3; Be equipped with gear 7 19, gear 6 18 on two 6, the side of gear 7 19, gear 6 18 is respectively equipped with electromagnetic clutch, and a parallel side of two 6 is provided with one 5; Be provided with gear 24, gear 37, gear 48 for one 5; Gear 24 and gear 7 19 engagements, gear 37 and gear 6 18 engagements, gear 48 meshes with gear 5 17 on three 9; Pass gearbox 10 for three 9 and insert in the boring cutter bar 16, three 9 the other end is provided with leading screw 12 and silk braid 11 engagements, and the helical teeth that silk braid 11 other ends are provided with on helical teeth plate 15 and the knife rest 14 is slidingly matched, and knife rest 14 front ends are provided with cutter 13.

its course of work is: set radial feed distance and speed; Connect the selected gear that connects of electromagnetic clutch, the leading screw 12 on connection motor 1 drives three 9, three 9 through gear with transmission of power rotates silk braid 11 displacements that cooperate with it; 15 displacements of pulling helical teeth plate; Helical teeth slide displacement on helical teeth plate 15 and the knife rest 14 makes knife rest 14 drive cutters 13 and helical teeth plate 15 do the displacement of vertical direction, reaches the effect of radial feed.
