Abstract

The utility model discloses a manual automatic changing device for cutter feed for a drill-milling machine. The utility model belongs to the class of a metal cutting machine tool. A middle shaft is supported in parallel on a headstock. A worm gear fixed to the upper part of the middle shaft is engages with a worm which extends from the upper part of the headstock and is connected with power. A gear fixed to the end of the middle shaft is engaged with a gear which is sheathed in a sliding mode on a shaft neck on a sharing shaft and is supported in parallel by the gear fixed to the end of the middle shaft. The gear fixed to the sharing shaft is engaged with a rack on a main shaft. A handle seat is fixed to the end of the sharing shaft. An electromagnetic clutch is arranged on a shaft neck of the inner side of the handle seat. One half of the electromagnetic clutch can slide in a shaft direction on the shaft neck of the sharing shaft. The other half of the electromagnetic clutch is fixed to the end surface of the gear sheathed in a sliding mode on the sharing shaft. When a cutter enters and is withdrawn manually, the main shaft and the cutter on the main shaft can move up and down by rotating a handle. The power supply of the electromagnetic clutch is switched on, the two halves of the electromagnetic clutch are attracted. The cutter is driven to move up and down by dynamic force through the middle shaft, the sharing shaft and the main shaft. Manual operation and automatic feed can be optionally transformed by pressing a button. The utility model has the advantages of simple operation, low labor intensity, and high work efficiency.

Description

The manual-automatic change-over device of drilling and milling machine tool feeding

Technical field

The utility model belongs to the Metal Cutting Machine Tool class, especially a kind of device that is used for the manual-automatic change-over of drilling and milling machine feed part.

Background technology

With drilling and milling machine workpiece is processed, generally be to stir gear in the case by rotating handle on the headstock, thereby moving up and down, finishes the vertical tooth bar on the main shaft of drive and its engagement, if have automatic feed mechanism, also need coupled clutch to be separated with main transmission with pulling fixed handle, rotate another handle again, stir the shifting slide gear on the stub, make, reach the purpose of autofeed withdrawing from the power transmission gear of headstock and the gears engaged on its common axis.The said structure troublesome poeration, labour intensity is big, and work efficiency is low.

The utility model content

When solving in the above-mentioned prior art manual-automatic change-over tool feeding, troublesome poeration, the problem that labour intensity is big, work efficiency is low, the technical solution of the utility model is: the jackshaft that level is arranged at the left and right sides of drilling and milling machine headstock tank wall upper support, worm engaging on it on fixing worm gear and the vertical worm shaft that stretches out from headstock top, join with power, the gear that jackshaft one end is fixing and the gears engaged of common axis upper sliding sleeve on axle journal of supporting in parallel, the tooth bar engagement on gear of fixing on the common axis and the vertical main shaft; One termination of common axis is installed with handle set, on the axle journal between the gear of handle set and this upper sliding sleeve, electromagnetic clutch is installed, its half can be on the axle journal of common axis axial slip, second half is fixed in the gear face that slides on the common axis.

When manual forward and back cutter, the electromagnetic clutch no power, its two halves separate, and turning handle drives common axis and rotates, and because of gear fixing it on and the tooth bar on the main shaft mesh, can drive main shaft and move up and down, and the cutter of installing on the main shaft also moves up and down; When the need auto-feed, start button is connected the power supply of electromagnetic clutch, its two halves adhesive, and gear and electromagnetic clutch on the common axis are integral, and the gear of power on jackshaft, common axis reaches main shaft, main shaft moved up and down drive the cutter servo-actuated.

A button can make manually because the conversion of said structure only need be pressed, arbitrarily conversion automatically, so simple to operate, labour intensity is little, the work efficiency height.

Description of drawings

Fig. 1 is the right view of the utility model drilling and milling machine headstock and column connecting portion;

Fig. 2 is the A-A profile of Fig. 1.

The specific embodiment

Among Fig. 1, headstock 1 is fixed on the front of the column 2 of drilling and milling machine, and the lower side of headstock 1 is equipped with handle set 3.

Among Fig. 2, on the tank wall of the left and right sides of headstock 1, be supported with jackshaft 5 with bearing, worm engaging on worm gear of fixing on it 6 and the vertical worm shaft 4, worm shaft 4 joins with the power on headstock top, and an end of jackshaft 5 is fixed with gear 7, and common axis 9 is supported on two tank walls of headstock 1 abreast with jackshaft 5, slide over gear 8 and gear 7 engagements on its axle journal, with tooth bar 11 engagements on the main shaft 12 of the fixing gear 10 of common axis 9 and mounting cutter; One end of common axis 9 is installed with handle set 3, can be equipped with between the tank wall of seat and headstock 1 and cover 14, its end face is fixed on the external box wall, on lid 14 the axle journals with interior common axis 9, electromagnetic clutch 13 is installed, second half is installed in spline or feather key on the axle journal of common axis 9, and one is semifixed on the end face of gear 8.

In order to make the more convenient to operate of electromagnetic clutch 13, can make the handle of installing on the handle set 3 17 hollow, its top is equipped with button 18, one end of guide rod 19 and knob 18 are fixing, the hollow hole that the other end passes handle 17 inserts in the handle set 3, is with compression spring 20 on the axle journal of the hole interstation on pillow block on the guide rod 19 and the handle 17; Pass on the annular distance wall that covers 14 holes at common axis 9 and to be fixed with dead ring 15, its ring stretches into the annular space of handle set 3, and the ring end is fixed with conducting ring 16, and guide rod 19 its end when nature does not contact with conducting ring 16; In the side of conducting ring 16 binding post 21 is arranged, have through wires hole 22 near the dead ring the binding post 21 15, lead one terminates on the binding post 21, and the other end passes through wires hole 22 and links to each other with electrical interface.

When inching button 18, guide rod 19 compression springs 20, its termination and conducting ring 16 connected, and conductor and electromagnetic clutch 13, brush 23, the electrical interface that constitutes by handle set 3, common axis 9 constitutes a closed-loop path again, thus the suction of realization electromagnetic clutch 13 from.
