Abstract

The utility model discloses a grinding type pulverizer which is especially suitable for the drilling process of various parts. The utility model is composed of a power case which is composed of a plurality of drill bits and driving parts, and a slip drill plate which moves along a guide post depending on the spring action. The grinding type pulverizer can carry out the multihole drilling and realize the functions of self-holding and self-resetting. Therefore, the work efficiency is high, and the work efficiency is improved 3-10 times, compared with the ordinary drill press. In addition, a stretching hinge axis used for regulating the pitch of holes and a tail clamping plate used for fixing the principal axis location of the drill bits are arranged in the power case. Therefore, workpieces with different pitches of holes can be processed only by replacing the different drill plates.

Description

Grinding type pulverizer

The utility model relates to the drilling equipment in a kind of machining, is specially adapted to the boring processing of part in addition of various dish classes.

In existing technology, in order to improve the dish class drilling efficiency of part in addition, what generally adopt all is specific drilling tool." the 476th page of Metal Cutting Machine Tool jig Design handbook." jig atlas " the 20th page goes up porous drill bit device of introducing, its complex structure, and the manufacturing cost height, and also the pitch-row of drill bit is fixing and nonadjustable, and its unicity is strong, and the scope of application is little.

The purpose of this utility model is at the deficiencies in the prior art, for the scope of application that enlarges its bull drilling equipment is designed a kind of Universal adjustable bull drilling equipment.

The purpose of this utility model realizes that by following scheme a headstock and a dependence spring action that it is made up of several drill bits and drive disk assembly are formed along the slip bushing plate that guide pillar moves.Connect in order to transmit moment of torsion by the main shaft of a power transmission shaft that has a trough with drilling machine.During work, this device can directly be fixedly mounted on the workbench of upright drill, drill press spindle moves downward, snap in the groove of headstock power transmission shaft, it is downward along two guide pillars with the lathe main shaft to drive headstock and slip bushing plate, borrow spring force to make the bushing plate workpiece pressing, workpiece can be located (not drawing among the figure) with v block.In headstock, drive a central gear and several satellite gears by power transmission shaft, each satellite gear connects the hinge axis that can stretch, and drives the drill bit rotation by fixed bearing block, carries out the porous drilling.After the process finishing, under the effect of spring force, headstock moves upward, drill bit is withdrawed from from processed part in addition and bushing plate, and under the effect of additional springs and support ring, bushing plate moves upward then, form the space of clamping workpiece, the centre bore of adjusting drill bit when needs apart from the time, unclamp the screw of bearing block afterbody clamping plate earlier, by the stretching hinge axis drill bit is moved in the corresponding drill bushing hole that can insert bushing plate freely.And then the bridge screw of bearing block afterbody is fastening, just can reach the purpose of adjusting.So, for different workpiece, only need to be equipped with different brill plates and get final product.

Utilize accompanying drawing to further describe embodiment of the present utility model below:

Fig. 1 is a structure cutaway view of the present utility model;

Fig. 2 is the cutaway view of headstock;

Fig. 3 is that the A of Fig. 2 is to structure chart.

In Fig. 1, label (2) is a headstock; Label (3) is that guide pillar and adopt with base (9) is rigidly connected, be with slip bushing plate (8) on the guide pillar (3), spring (5) is housed between it, additional springs (6), and support ring (7), be fixed with the pull bar (4) that has the shaft shoulder on the slip bushing plate (8), thereby under the motionless condition of guide pillar (3), make drill bit and bushing plate when work, can realize that oneself starts building into.Can automatically reset after having worked.

In Fig. 2, power is passed to headstock power transmission shaft (1) by drill press spindle, power transmission shaft (1) drives a central gear (10) and several satellite gears (11), all connect a stretchable hinge axis (12) on the axle of each satellite gear, universal joint (13) is equipped with at the two ends of hinge axis (12), the lower end connects the bearing block (14) of buried bearing, the auger axis (15) of bearing block (14) bottom is assembled according to known bull brill technology with drill bit (17), and has the locking nut (16) that can regulate the drill bit high and low position.

In Fig. 3, label (18) is a headstock housing base plate, makes to have the double adjustment hole or the groove of different five equilibriums on it, adjusts the position of fixed drill bit pitch-row by several bearing block afterbody clamping plate (19) screws (20) that have groove.

Grinding type pulverizer of the present utility model, line and clamping time have been removed from, shortened process time, can improve 3～10 times of work efficiency than common driller, the position that utilizes simultaneously stretching hinge axis in the transmission case and bearing block afterbody clamping plate to adjust the required centre bore distance of drill bit, make bull fixedly drilling equipment be improved to grinding type pulverizer, thereby enlarged the scope of application.

Claims

1, a kind of Universal adjustable bull drilling equipment relies on spring (5) (6) effect and forms along the slip bushing plate (8) and the base (9) of guide pillar (3) motion by a headstock (2) that several drill bits and drive disk assembly form and one are housed, and it is characterized in that:

A) headstock (2) is by housing (18), central gear (10), and several satellite gears (11), stretching hinge axis (12), bearing block (14) is formed.

B) a pair of additional springs (6) and support ring (7) have been increased on the guide pillar.

C) slip bushing plate (8) is gone up with the fixing a pair of pull bar (4) that has the shaft shoulder of securing member.

2, Universal adjustable bull drilling equipment according to claim 1, it is characterized in that: universal joint (13) is equipped with at the two ends of stretching hinge axis (12), and the upper end connects satellite gear (11), lower end connecting axle bearing (14).

3, Universal adjustable bull drilling equipment according to claim 1 is characterized in that: bearing block (14) is fixed on housing (18) bottom with the afterbody clamping plate (18) that have groove with the securing member that is easy to dismantle.
