Abstract

Multifunctional electric rubber-stopper puncher The multifunctional electric rubber-stopper puncher relates to a tool applied in chemical experiment and official work. The puncher adopts drill and clamp that fit to perforate the straight and slant holes with different diameters on the rubber cork and books and bills. The utility model has the advantages of simple structure, convenient operation, saving time and labour and easy assembly and disassembly and easy desquamation, so it is fit for punching holes applied in such areas for binding and punching as follows: middle schools, academies, technological institute, petrochemical industry, medical and sanitary undertakings, pulic institution and industrial and mining enterprises.

Description

Multifunctional electric rubber-stopper puncher

The utility model provides a kind of rubber stopper multifunctional motor-driven card punch used when chemical experiment and document bookbinding.

Utility model patent 87205359 discloses the electronic card punch of a kind of rubber stopper, it has changed the method that traditional craft is punched on rubber, it is laborsaving not only to punch, and can also beat straight hole, inclined hole, but this electronic card punch still exists drill bit to pack, take off effort into, and drill bit is damaged the precision that drill bit grips the position because of folder does not tightly skid; The drill bit endoporus is difficult to furfur for educating the hole, and the method that also handy traditional usefulness is disclosed bar is disclosed it; Only be suitable for beating weak points such as rubber consent.

The purpose of this utility model is that a kind of rubber stopper that is not only applicable to of design punches, but also be suitable for the rubber stopper multifunctional motor-driven card punch that the bookbinding of document subpoena is punched, this card punch can not only be beaten straight hole, inclined hole, and the loading, unloading drill bit is convenient, and furfur is easy.

The purpose of this utility model realizes in the following manner, rubber stopper multifunctional motor-driven card punch is by base 1, compositions such as anchor clamps 2, drill bit 3, drill chuck 4, motor 5, rack slide 6, gear 7, handle 8, support 9, angular adjustment apparatus.Top board 16, the lower platen 18 of anchor clamps 2 are fused by bolt 15, have the different elongate slots of width on the lateral attitude of upper and lower pressing plate, drill chuck 4 is made up of end cap 11, bolt 12, collet body 13, and bolt 12 is fixed together end cap 11, collet body 13.The angle adjuster of anchor clamps 2 is installed in rotary support 19 on the supporting plate 21, bearing pin 20, angle adjustment bearing 24, forms with the angle adjustment support 25 of top board 18 hinge joints.Supporting plate 21 is connected with base 1 slide rail.The upper end of drill bit 3 has the microscler flange of garden arc.

Below in conjunction with accompanying drawing structure of the present utility model and operating position are illustrated.

Fig. 1. the positive schematic diagram of the utility model complete machine structure.

Fig. 2. the utility model complete machine structure left side schematic diagram.

Fig. 3. drill bit 3 among Fig. 2, drill chuck 4 assembling schematic diagrames.

Fig. 4. the A of the assembling schematic diagram of drill chuck and drill bit is to schematic diagram.

Fig. 5. the structural representation of anchor clamps.

Fig. 6. on, schematic diagram that lower platen is slotted.

With reference to Fig. 1-4, the power of motor 5 is 250 watts, and voltage is 220 volts, and rotating speed is 1400 rev/mins.Motor 5 usefulness bolted are moved handle 8 on rack slide 6, handle 8 is by gear shaft 10, and tooth bar 7 slides up and down rack slide 6, drives motor 5 simultaneously and moves up and down.Drill chuck 4 directly is fixed on the motor shaft by trip bolt 14.Bolt 12 is fixed together end cap 11 collet bodies 13.

Drill bit 3 adopts cold drawn light-wall pipe to make, and is slightly larger than following aperture apart from the aperture of cutting edge more than 10 millimeters, so that furfur.The upper end of drill bit 3 has the microscler flange of garden arc, the effect that has arc location, garden and transmit moment of torsion, and drill chuck 4 bottoms correspondingly have the elongate slots of band garden arc, during the dress drill bit.The elongate slots of the microscler flange that has the garden arc of drill bit being aimed at band garden, drill chuck bottom arc upwards pushes away.And the inhour rotation when unloading, as long as clockwise rotate drill bit, can take off the elongate slots of the microscler flange aligning band garden arc of band garden arc until getting final product work near screw 14.Aluminium head 3 lower end Wai Yuan are 30 ° of chamferings, so that cutting edge is sharp.

With reference to Fig. 5, Fig. 6, the bolt 15 that top board 16, lower platen 18 usefulness are with spring 17 fuses.Have the different elongate slots of width on the upper and lower pressing plate, to satisfy the straight hole of beating different-diameter, the requirement of inclined hole or document subpoena bookbinding punching.

Supporting plate 21 is connected with base 1 slide rail, can move horizontally along horizontal.Supporting plate can be fixed on needed operating position under the effect of the fastener on the base.Angle adjustment bearing 24 is fixed on the left end of supporting plate 21, angle adjustment support 25 and the inboard hinge joint of lower platen 18 left ends.When anchor clamps 2 are in level, beat straight hole.When extracting lower platen 18, upper and lower pressing plate is along rotary support 19, bearing pin 20 is upwards mentioned, when again the coupking shaft of angle adjustment support 25 being put into the different tipper of angle adjustment bearing 24, can change the angle of inclination of anchor clamps 2, can beat inclined hole this moment.

Two ejector pins 23 are housed on the relevant position of slotting with upper and lower pressing plate on the supporting plate 21, and edge and two corresponding positions of ejector pin are marked with " 1,2 " label within it.Rubber stopper when punching, as the diameter of the thin end of rubber stopper during, then will " 1 " aim at " 0 " on the base greater than 25 millimeters, the thick groove aligning " 0 " that is about in the middle of the supporting plate punches again; ,, be about to stria aligning " 0 " and punch again less than 25 millimeters as diameter then with " 2 " aligning " 0 ".Then not limited to document subpoena bookbinding punching.

On supporting plate 21, beat the corresponding center of rubber consent " 1,2 ", two ejector pins 23 are housed with two.After punch in the hole, motor 5 stops operating, the drill bit 3 that will contain bits this moment heads on ejector pin 23 to be continued toward pressing down, till touching valve rubber 22, ejector pin can be considered the rubber in the drill bit to be worth doing upwards jack-up one segment distance, when again to another rubber stopper punching, its bits that newly get out then eject the bits of front in drill bit bore.

In the support 9 back-moving spring is housed, when off working state, can makes motor 5 remain on raised position.

This rubber plug multifunctional motor-driven card punch is reasonable in design, simple in structure, easy to use, time saving and energy saving, this electric perforator can be beaten at rubber straight hole and the oblique hole of different-diameter beyond the Great Wall, can satisfy again the requirement of document subpoena bookbinding punching, and go out bits easily, be suitable for chemical laboratory or other administrative institutions in industries such as secondary school, universities and colleges, scientific research institute, institute's oil chemical industry, medical and health, use in the document subpoena bookbinding of industrial and mining enterprises.
