Abstract
The utility model provides a shell drilling machine for metal-shell hazardous articles. The shell drilling machine is composed of a drilling machine spindle, a spindle driving device, a drill, a workpiece die clamp and a spindle feeding device, and is characterized in that a spindle moving guide rail is arranged on one side of the drilling machine spindle, the spindle feeding device comprises a feeding gearbox connected with the drilling machine spindle, a feeding motor connected with the feeding gearbox, a pressure sensor and a limiting baffle, and the pressure sensor and the limiting baffle are located on the two sides of the feeding motor. The shell drilling machine is fast to brake and convenient to adjust, reduces the probability that cuttings enter a metal shell and ignite powder in the metal shell, lowers working difficulty, reduces working risk factors and guarantees the safety of workers.
Description
Technical field
The utility model relates to Machining Technology field, relates in particular to a kind of metal-back dangerous material shell drilling machine.
Background technology
Be full of the metal-back product of inflammable dangerous material for inside, during for the burning of test inflammable thing, the pressure changing of metal-back inside need to process through hole on housing.All adopt at present common bench drilling machine as drilling machine, use standard fluted drill, complete bore operation by artificial execute-in-place.In the time that drill bit drills through housing wall, if feed-disabling at once, drill bit will be charged into enclosure interior, its inner inflammable thing of drilling, drill bit is charged into enclosure interior and also can be caused smear metal to fall into inflammable thing, because cutting temperature is far above the burning-point of inflammable thing, drill bit is charged into housing or smear metal and is fallen into inflammable thing and all probably cause the inflammable thing of igniting, and then explosion caused.Adopt although also have at present the safety measure that installs shoulder guard on drilling machine additional,, owing to fundamentally not solving drill bit and charge into the problem of enclosure interior, so, cannot guarantee operating personnel's safety, personal safety accident happens occasionally.The drilling safe of this series products has become problem demanding prompt solution in testing experiment.
Given this, be necessary to provide a kind of new metal-back dangerous material shell drilling machine to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of braking quick, safe and reliable, easy to adjust metal-back dangerous material shell drilling machine.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of metal-back dangerous material shell drilling machine, by drill spindle, be positioned at the main shaft driving device of drill spindle top, be positioned at drill bit and the workpiece die clamp of drill spindle below, be positioned at the main shaft proceeding equipment composition of drill spindle one side, it is characterized in that: described drill spindle one side is provided with main axle moving guide rail, described main shaft proceeding equipment comprises the feed gear box being connected with drill spindle, the feeding motor being connected with feed gear box, be positioned at pressure sensor and the postive stop baffle of feeding motor both sides.
As the further improvement of the technical program, worm gear, worm screw that described feed gear box comprises feeding spur gear, is connected with feeding spur gear, described worm screw one end is provided with hand feed wheel, and the other end is connected with feeding motor.
Compared with prior art, the utility model metal-back dangerous material shell drilling machine, by pressure sensor being set in feeding motor side, torsion when being used for monitoring feeding motor and driving drill spindle to move up and down fades to the pressure of feeding motor side, in the time that drill bit drills through housing, pressure reduces rapidly, the running of feeding motor automatic stop, braking is quick, easy to adjust, reduce smear metal and entered the ignite possibility of its internal charge of metal-back inside, reduce work difficulty, reduce work risk factor, guaranteed staff's safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of metal-back dangerous material shell drilling machine described in the utility model.
The specific embodiment
Refer to shown in Fig. 1, the utility model provides a kind of metal-back dangerous material shell drilling machine, by drill spindle 1, be positioned at drill spindle top main shaft driving device 2, be positioned at drill spindle below drill bit 3 and workpiece die clamp 4, be positioned at the Zhu Zhou Jin Give installation composition of drill spindle one side, described drill spindle one side is provided with main axle moving guide rail 5, and described Zhu Zhou Jin Give device comprises the feed gear box 6 being connected with drill spindle, the feeding motor 7 being connected with feed gear box, the pressure sensor 8 that is positioned at feeding motor both sides and postive stop baffle 9.Worm gear 62, worm screw 63 that described feed gear box comprises feeding spur gear 61, is connected with feeding spur gear, described worm screw one end is provided with hand feed wheel 10, and the other end is connected with feeding motor.
The utility model in use, drill spindle 1 drives by main shaft driving device 2, utilize Zhu Zhou Jin Give device drive into, in the time that feeding motor drives drill spindle 1 feeding, feed gear box 6 can be to reverse torsion of feeding motor, and torsion changes pressure conduction feeding motor 7 sides into, utilize the variation of pressure sensor 8 monitoring pressures, in the time that drill bit 3 drills through the housing of metal-back dangerous material 100, pressure reduces rapidly, the running of feeding motor automatic stop.
The above, be only most preferred embodiment of the present utility model, utilizes the method for above-mentioned announcement in the variation slightly and the modification that do not depart from technical solutions of the utility model scope situation, all belongs to the scope of claims protection.
