Description
Technical field
The utility model relates to engineering machinery field, is specially a kind of multiple-drill press dividing into groups to start.
Background technology
Traditional multiple-drill press, if run into any stratum a little hard, single motor starts resistance of start square required when cannot meet startup, it is excessive again that multiple electric motors starts total current simultaneously, there is larger impact to electrical network, master switch can be caused to trip, then cause complete machine to start.Meanwhile, traditional multiaxis drilling rod, the body of rod of its drilling rod is cylindrical structural, when tackling hardpan, creeping into, cutting operation is very difficult, causing drilling efficiency low, meanwhile, columniform drill bit lacks the structure in aperture, location, therefore easily causes drill bit to depart from center.
Summary of the invention
The purpose of this utility model is, provide a kind of divide into groups start, with taper bit so as with the multiple-drill press that hardpan is holed.
In order to achieve the above object, the utility model is achieved in that
Divide into groups the multiple-drill press started, and it comprises multiple motor, headstock, output shaft, drilling rod, drill bit, drill pipe cage and lifting appliance; Each motor drives one or two output shafts by headstock; The output shaft that each motor drives and the output shaft that other motor drive do not link, and drilling rod comprises the linkage section that is connected with output shaft and stirs drill pipe section; The body of rod of drill bit is cone shape, and it reduces until drill tip from starting body of rod diameter with the junction of stirring drill pipe section gradually; The body of rod external surface stirring drill pipe section and drill bit has spiral trajectory, discontinuous stirring vane, and stirring vane is provided with cutting teeth.
For simplifying the syndeton of output shaft and drilling rod, alleviate the weight of connector and simplify the upkeep operation of syndeton, the multiple-drill press of described divided into groups startup, output shaft and the syndeton of the linkage section of drilling rod are that direct six sides are connected, particularly, output shaft is designed to six side's male joint forms, is provided with six side's female joints in the linkage section of drilling rod, and output shaft realizes the connection with drilling rod by the connection with six side's female joints in drilling rod linkage section; The linkage section of drilling rod and six side's female joints are by being welded and fixed.
The multiaxis taper drilling rod of described divided into groups startup, drill bit tapering is 15 ° ~ 40 °.
The multiple-drill press of described divided into groups startup, motor unit comprises three motor, word order five gears in headstock, gear in headstock is connected with output shaft, wherein, two, left side gear engages each other and is driven by a motor, this motor drives two drilling rods in left side, two gears in right side engage each other and are driven by another motor, this motor drives two drilling rods in right side, the gear of middle is driven by a motor separately, and this motor drives central authorities' drilling rod.
The utility model adopts above-mentioned design, each motor drives at least one drilling rod respectively, but each drilling rod does not link, so, multiple motor can start respectively or start simultaneously, so, reduce and start instantaneously to the impact of electrical network, make the machine start easily, and adopt the drill bit with conical structure, being conducive to drill bit enters in hardpan, uses the discontinuous stirring vane with spiral trajectory, fully can stir hack and not form casting phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of this machinery.
Fig. 2 is the structural representation of this mechanical headstock internal gear interlock.
Fig. 3 is the partial enlarged drawing in Fig. 1.
Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of multiple-drill press dividing into groups to start, it comprises the motor unit, headstock 2, output shaft 10, drilling rod 3 and the drill pipe cage 5 that are made up of three motor 1; Word order five gears in power 2 casees, wherein, two gears 12 in left side engage each other and are driven by a motor 1, two gears 14 in right side engage each other and are driven by another motor 1, the gear 13 of middle is driven by a motor 1 separately, and the gear in headstock 2 is connected with output shaft 10; Drilling rod 3 comprises the linkage section that is connected with output shaft 10 and stirs drill pipe section 4; For ease of being applied to hardpan, improve the cutting power of drill bit and reduce drill bit resistance, the body of rod of drill bit 6 is cone shape, and its diameter reduces until drill tip from body of rod diameter gradually; For ease of stirring the earth of chopping, the body of rod external surface of drill bit 6 is provided with has spiral trajectory, discontinuous stirring vane 15, and stirring vane 15 is provided with cutting teeth 7.
As shown in Figure 3, for simplifying the syndeton of output shaft 10 and drilling rod 3, alleviate the weight of connector and simplify the upkeep operation of syndeton, the multiple-drill press of described divided into groups startup, output shaft 10 and the syndeton of the linkage section of drilling rod 3 are that direct six sides are connected, and particularly, output shaft 10 is designed to six side's male joint forms, be provided with six side's female joints 9 in the linkage section of drilling rod 3, output shaft 10 realizes the connection with drilling rod 3 by the connection with six side's female joints 9 in drilling rod linkage section; The linkage section of drilling rod 3 and six side's female joints 9 are by being welded and fixed.
The multiaxis taper drilling rod of described divided into groups startup, drill bit segment 6 tapering of drilling rod 3 is 15 ° ~ 40 °.
The utility model adopts above-mentioned design, each motor drives at least one drilling rod respectively, but each drilling rod does not link, so, multiple motor can start respectively or start simultaneously, so, reduce and start instantaneously to the impact of electrical network, make the machine start easily, and adopt the drill bit with conical structure, being conducive to drill bit enters in hardpan, uses the discontinuous stirring vane with spiral trajectory, fully can stir hack and not form casting phenomenon.
