Abstract
The utility model discloses a drill press structure capable of improving the operation safety, comprising a base and a working table and a lifting rod which are both arranged on the base. A lifting table is in sleeved connection to the lifting rod, and a motor is fixed on the lifting table; a rotating shaft of the motor penetrates through the lifting table, and a drill bit is fixed on the rotating shaft; a lifting cranking bar is arranged on the lifting table in which a travel switch and a contactor are arranged, and the travel switch and the contactor are connected in series in a control circuit in which the motor is located. By adopting the structure, the safety of drilling holes is improved, and the energy consumption of the drill press is reduced.
Description
Technical field
The utility model relates to field of machining, specifically a kind of drilling machine structure that can improve processing safety.
Background technology
Drilling machine refers to mainly use the lathe of drill bit machining hole on workpiece, and bit is main motion usually, and drill bit moves axially and is feed motion.Drilling machine is simple in structure, and machining accuracy is relatively low, can drill through hole, blind hole, changes special tool, can expand, spot-facing, reams or carries out the processing such as tapping.According to the difference of type, drilling machine can be divided into bench drill, upright drill, radial drilling machine, milling and drilling machine, deep hole drilling machine etc.
The operation principle of drilling machine is also very simple, driven by motor brick High Rotation Speed, turn lifting handle, lifting platform is moved downward, and drill bit also carries out bore operation along with moving downward to workpiece, hole complete after, the turn lifting handle moves upward lifting platform again, and drill bit is away from workpiece.There is certain danger in this course of work, because after boring is complete, as long as be not related to the power down source, motor can rotate always, operating personnel are come to harm because of negligence of operation, and simultaneously, drill bit does not carry out drilling operation and always rotation, certainly will cause the waste of resource, so that power consumption is higher.
The utility model content
The purpose of this utility model provides the drilling machine structure that a kind of security is higher, can reduce energy consumption.
The utility model is that the technical solution problem is achieved through the following technical solutions: the drilling machine structure that can improve processing safety, comprise base and be arranged on workbench and elevating lever on the base, be socketed with lifting platform on the elevating lever, be fixed with motor on the lifting platform, lifting platform is passed in the rotating shaft of motor, be fixed with drill bit in the described rotating shaft, also be provided with the lifting rocking handle on the lifting platform, be provided with travel switch and contactor in the described lifting platform, described travel switch and contactor are serially connected in the control loop at motor place.
Workbench is used for laying workpiece to be holed; Lifting platform can move up and down along elevating lever, and the lifting rocking handle plays the effect of control lifting platform motion state, and by stirring the lifting rocking handle, selecting lifting platform is to rise or descend; By introducing travel switch and contactor, duty to motor is controlled, when the boring end, when lifting platform moves upward, trigger travel switch, contactor is disconnected, and motor quits work, and moves downward and work as lifting platform, in the time of namely will beginning to hole work, trigger travel switch, make contactor closed, motor is started working.
Described elevating lever is perpendicular to base, and elevating lever is also perpendicular to workbench.
Described drill bit be positioned at workbench directly over, and the projection of drill bit on workbench is positioned at the center of workbench.
Described lifting rocking handle is V-shaped.
Described lifting platform is vertical with elevating lever.
The rotating shaft of described motor and drill bit are positioned on the same vertical curve.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is by series connection travel switch and contactor in the control loop at motor place, so that the duty of motor can reasonably be adjusted according to need of work, be bore operation complete after, motor can quit work immediately, and during bore operation, do not affect the normal operation of motor.Like this, the danger when having reduced to a great extent operation, when especially not carrying out bore operation, operator's notice is not very concentrated relatively, carelessness occurs easily, and then may cause the injury of health, so put from this, has improved the security of operation.
(2) the relatively traditional drilling machine of the utility model, motor is not worked always, but just works according to bore operation the time, has therefore reduced the energy consumption of drilling machine, is conducive to reduce production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The name that Reference numeral is corresponding is called: 1, base, 2, workbench, 3, elevating lever, 4, lifting platform, 5, motor, 6, rotating shaft, 7, drill bit, 8, the lifting rocking handle, 9, travel switch, 10, contactor.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, present embodiment comprises base 1 and is arranged on workbench 2 and elevating lever 3 on the base 1, be socketed with lifting platform 4 on the elevating lever 3, be fixed with motor 5 on the lifting platform 4, lifting platform 4 is passed in the rotating shaft 6 of motor 5, is fixed with drill bit 7 in the rotating shaft 6, as preferably, the drill bit 7 of present embodiment be positioned at workbench 2 directly over, and the projection of drill bit 7 on workbench 2 is positioned at the center of workbench 2.
Also be provided with lifting rocking handle 8 on the lifting platform 4 of present embodiment, as preferably, the lifting rocking handle 8 of present embodiment is V-shaped.
Be provided with travel switch 9 and contactor 10 in the lifting platform 4 of present embodiment, travel switch 9 and contactor 10 are serially connected in the control loop at motor 5 places.Contactor 10 is in normally off under normal circumstances, when lifting platform 4 moves upward, triggers travel switch 9, and contactor 10 is disconnected, and the complete rear motor 5 of holing so also quits work thereupon.
The elevating lever 3 of present embodiment is perpendicular to base 1, and elevating lever 3 is also perpendicular to workbench 2.
The lifting platform 4 of present embodiment is vertical with elevating lever 3.
Rotating shaft 6 and the drill bit 7 of the motor 5 of present embodiment are positioned on the same vertical curve.
Operation principle of the present utility model is: workpiece that will be to be holed is fixed on the workbench 2, stir lifting rocking handle 8, lifting platform 4 is moved downward, drill bit 7 begins workpiece is holed, hole complete after, again stir lifting rocking handle 8, lifting platform 4 is moved upward, at this moment, triggered travel switch 9, contactor 10 is disconnected, and namely the control loop of motor 5 also disconnects, and motor 5 quits work.
As mentioned above, then can realize well the utility model.
