Abstract

The utility model relates to a fast fiercer of multiple-position belonging to mechanical field. The fast fiercer mainly comprises a connecting sleeve, a connecting head, an upper rotary plate, a lower rotary plate, Morse tapered main shafts, an indexing sleeve, a compressing shaft, an indexing positioning pin and a compressed cam. Three directions of the lower rotary plate are respectively arranged with Morse tapered main shafts, enabling the common drilling machine to realize fast drill-changing (or knife-changing) without stopping the machine, thereby the integrated process of drilling, amplifying, hinging, scraping, chamfering, tapping and other procedures to the work-piece can be conducted continuously, further being capable of improving the drilling effects by 2-3 times. The utility model really belongs to high-efficiency accessory for matching the machine tool or a duel-purpose drilling-and-tapping machine.

Description

Multidigit rapid drilling device

The utility model is a kind of multidigit rapid drilling device that relates to mechanical field.

At present, the drill press spindle on the market can only be installed a drill chuck, and a kind of drill bit of specification can only be installed when promptly using at every turn, must shut down as bit change more---and this certainly will mistake and influence work efficiency.

The purpose of this utility model is exactly in order to overcome above-mentioned drawback; can not shut down fast quick change and bore (or cutter) for common driller (or bore attack dual-purpose machine) provides a kind of, to workpiece bore continuously, expand, cut with scissors, scrape, the efficient annex of operation comprehensive processes such as chamfering, tapping.

The purpose of this utility model mainly is in three different azimuth of lower rotary table seat bottom surface Mohs awl main shaft to be installed respectively, side at the lower rotary table seat is installed the calibration dowel, and at the middle calibration cover of installing of upper and lower subbase, in the calibration cover compression axis is installed, the adapter sleeve by connector is installed and top bottom-disc seat are right after and realize again.

Specify below in conjunction with the structure of accompanying drawing the utility model multidigit rapid drilling device.Fig. 1 is the structure chart of the utility model multidigit rapid drilling device.：1—— 2—— 3——4—— 5—— 6——7—— 8—— 9——10110——104 11—— 12——13—— 14—— 15——16—— 17—— 18——19—— 20—— 21——22—— 23—— 24——25—— 26—— 27——28——

The technical characterictic of the utility model multidigit rapid drilling device is described in detail in detail below.Lower rotary table seat 23 in the form of annular discs is equipped with three Mohs awl main shafts 13, and three Mohs awl main shafts 13 are mutually 120 ° of angle orientation and install respectively on the disc of lower rotary table seat 23; The upper end of Mohs awl main shaft 13 is fastened with down clutch pawl 8; The top circumference of lower rotary table seat 23 is fastened with down ring gear 17; The following circumference of top rotary table seat 15 is fastened with ring gear 16; Last ring gear 16 coincide mutually with following ring gear 17; Top rotary table seat 15 and the lower rotary table seat 23 middle calibration covers 14 that are equipped with; In the calibration cover 14 compression axis 28 is housed, its lower end is equipped with and compresses cam 26; Compressing cam 26 is connected with to take off and closes handle 20; The top cover inboard of top rotary table seat 15 is pushed up in the upper end of compression axis 28; In the one side hole of lower rotary table seat 23 spring 21 and calibration dowel 22 are installed; The other end of calibration dowel 22 withstands the groove of calibration cover 14; Connector 1 and spring 2 are installed in the adapter sleeve 5, and clutch pawl 6 is equipped with in the lower end of connector 1; Adapter sleeve 5 is fastening with top rotary table seat 15.

The manufacturing of the utility model multidigit rapid drilling device is described in detail in detail below.Top rotary table seat 15 and lower rotary table seat 23 form by aluminium alloy casting or pig iron founding and through machining; Other hardware all with No. 45 steel through lathe or plane, mill, machining such as brill forms, because of manufacture craft is simple, do not repeat them here.

During use, unload the drill chuck on the drill press spindle earlier, again the utility model multidigit rapid drilling device is installed on the drill press spindle, the work of can turning round of the drilling tool of installing drill chuck and required three kinds of different sizes for respectively three Mohs awl main shafts 13; In the running course of work; select another specification drilling tool for use as need; can under not shutdown situation, replace fast; during transposition,, compress 26 on cam and drive compression axis 28 and rising top rotary table seat 15 as long as pulling downwards to take off closes handle 20; clutch pawl 6 and following clutch pawl 8 are broken away from; then rotate lower rotary table seat 23 by counter clockwise direction, can hear " clickly " location sound, transposition promptly comes to an end.

In sum; the utility model multidigit rapid drilling device is rational in infrastructure; manufacturing process is simple; utilize it can make common driller realize not shutting down fast quick change and bore (or cutter); thereby can bore continuously workpiece, expand, cut with scissors, scrape, the comprehensive process of operation such as chamfering, tapping; can improve common driller effect 2-3 doubly, a kind ofly really dispose the efficient annex that drilling machine or brill are attacked dual-purpose machine.
