Abstract

The utility model relates to a headstand masses drill, which comprises an electromotor (1), a handle wheel (6), a tumbler gear (4), a lead screw (22), a gearbox (27), a mult-spindle box (26), a drill bit (14), a dual guide rail (23), a workpiece holder and other members. The utility model is characterized in that the masses drill is arranged under the workpiece holder, the multi-spindle box (26) is arranged above the gearbox (27), and the multi-spindle box (26) and the gearbox (27) are split and driven by an intermediate shaft (16). Because the masses drill is arranged under the workpiece and the workpiece is guided by the dual guide rail (23) and fed by a sliding plate (24), the metal bits are discharged easily, enabling small friction, no high temperature and high drill precision. Because the multi-spindle box (26) and the gearbox (27) are split, the multi-spindle box (26) can be replaced at will according to number of the drill. The utility model has the advantages of small drive power, convenient operation and applicability to deep-hole processing.

Description

Inverted Ni Zhifu drill

The utility model relates to a kind of processing equipment that is used for holing, a kind of specifically inverted Ni Zhifu drill that can once bore a hole or number hole.

Actual mechanical process in deep hole machining, because the friction of drill bit and workpiece to be machined, particularly the metal fillings of drilling can not in time be discharged, strengthened the friction of drill bit and workpiece, make it produce high temperature, to making coarse, the distortion of Workpiece boring, make drill bit annealing, crooked, wearing and tearing quickening simultaneously, burn, fracture sometimes even with drill bit.Even if the cooling fluid of using is also only cooled off top often, and be can't resolve the bottom, drill bit can only be withdrawed from cooling sometimes, take a part of drilling cuttings out of and bore again.When processing precise part or the workpiece that is not suitable for cooling off, then can only cool off naturally or divide and process for several times, useless like this worker, when useless, waste material.

The purpose of this utility model is to provide a kind of metal fillings that makes easily to discharge, and need not cool off and inverted Ni Zhifu drill that borehole accuracy is high.

The utility model is achieved through the following technical solutions: inverted Ni Zhifu drill mainly is made up of motor, handle wheel, Norton gear, leading screw, gearbox, axles box, drill bit, two guide rail, workpiece clamp etc., it is characterized in that: Ni Zhifu drill places the below of workpiece, axles box places the top of gearbox, and axles box and gearbox are split type and pass through the jackshaft transmission.

The utility model is because Ni Zhifu drill places the below of workpiece, and workpiece is led by two guide rails, the slide plate feeding, and metal fillings can easily be discharged downwards, and it is little to rub, and does not produce high temperature, the borehole accuracy height; Axles box and gearbox are split type, press drilling hole amount, can change axles box at any time; Adapted power power is little, and is easy to operate.

Fig. 1 is a side view of the present utility model.

Fig. 2 is a front view of the present utility model.

The utility model is described in further detail in conjunction with the embodiments will to contrast accompanying drawing below.

The utility model is an example with the template of 6 drill bits.Upright arm (1) top of inverted Ni Zhifu drill drilling machine is equipped with motor (8), and a side of upright arm (1) is equipped with scale of depth (7), handle wheel (6), gear seat (3), Norton gear support (2) successively.The output wheel (9) of motor (8) is connected with handle wheel (6) by the V-belt.On the Samsung support (2), be separately installed with two idle wheels and a feed gear wheel (4), be built-in with leading screw (21) between upright arm (1) and the base (20), the lower end of leading screw (21) is equipped with feeding worm gear (28), feed worm (29) is meshed with it, Samsung feed gear wheel (4) drives feeding worm gear (28), drives leading screw (22) and rotates.

The two guide rails (23) that are parallel to each other place the both sides of upright arm (1), workpiece slide plate (23) is fixed on two guide rails (23) with screw by slide plate pressing plate (11), be built-in with a screw in the middle of the slide plate (23), leading screw (22) passes in screw, depth needle (10) is housed on the slide plate pressing plate (11), match with scale of depth (7), can process the boring of different depth like this.Be connected with a perpendicular flat board (12) on the slide plate (24), two drill jig supporting plates (25) are equipped with in the lower end of slide plate (23), bushing plate (13) places on the drill jig supporting plate (25), and bushing plate (13) is formed workpiece clamp with dull and stereotyped (12), and is fastening by bolt (30).During use, drive handle wheel (6), drive leading screw (22) by feed gear wheel (4) and rotate, workpiece clamp can be moved up and down along two guide rails (23) by motor (8).

Base (21) is built-in with motor (20), gearbox (27) is connected with base (21), the output wheel (19) of motor (20) links to each other with the wheel for inputting (17) of gearbox by the V-belt, axles box (26) mainly is made up of pitch wheel, the number of gear and arrangement position are to be provided with according to the number and the arrangement position of holing, (the utility model is an example with 6 borings), axles box (26) places on the gearbox (27), the two is for split type and be connected by jackshaft (16), on the jackshaft (16), in, under be separately installed with bearing, on, the lower bearing installed inside has input gear (15), output gear (18), the output wheel (17) of jackshaft (16) is positioned at gearbox (27), the input gear (15) of jackshaft (16) is positioned at axles box (26), is meshing 6 gears that link to each other with drill bit around the axles box wheel for inputting (15).Output wheel in the motor drives gearbox, and, the gear that is meshed with it and links to each other with drill bit is rotated thereupon on every side by jackshaft drive axles box wheel for inputting.
