Abstract
A bench drill rotational speed display device belongs to drill machine technical field, which at least comprises a counting scale fixed under a follower pulley of the drill machine, a sensor rack fixed on a spindle box, a photoelectric sensor fixed on the sensor rack and straddled on the outer rim of the counting scale, a digital displayer connected with the photoelectric sensor by wire and mounted in front of the spindle box and a control circuit of the digital displayer. The outer rim of the counting scale is provided with a counting hole or a notch. The digital displayer is a four-figure nixie tube displayer or a four-figure liquid crystal display, which can display the rotational speed of the bench drill especially of continuous change bench drill clearly, accurately and instantaneously, and can be widely applied in bench drill or other drill machines.
Description
Technical field
The utility model belongs to the drilling machine technical field, more specifically to the improvement of the mensuration display device of drilling machine rotating speed.
Background technology
Existing bench drill does not have the mensuration display device of rotating speed mostly, indicates the different rotating speeds under the different gear stages at the most on a nameplate.The operator can select different gear stages according to desired rotating speed.Though this display mode is simple and crude, can be said to be suitable for the drilling machine that grade transmission is arranged.
The rotating speed of stepless change drilling machine is the important parameter that the operator should know.Being convenient to the operator is selected according to the difference of part material.The rotating speed of stepless change drilling machine in the past can not show intuitively that the operator can only estimate by rule of thumb.This estimation varies with each individual, and is very inaccurate.This just processes particularly to brill, and the brill processing of the degree of precision of strength member has brought difficulty.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides a kind of and can clear, accurately, immediately show the particularly numeric display unit of the bench drill rotating speed of stepless change drilling machine rotating speed of drilling machine.
Summary of the invention
In order to achieve the above object, the utility model is installed in by base, column, selective headstock, motor, main shaft, rack sleeve, drill chuck, driving pulley, is installed on the drilling machine that driven pulley, belt wheel cover and motor switch on the main shaft form.Which comprises at least the counting scale that is fixed on below the driven pulley, be fixed on sensor frame on the selective headstock, be fixed on the digital indicator that is installed in the selective headstock front and the control circuit thereof that straddle the outer intermarginal photoelectric sensor of counting scale on the sensor frame, be connected with photoelectric sensor with lead.Have counting on the outer rim of counting scale with hole or breach.
Photoelectric sensor straddles on the outer rim of counting scale.The one side emits beam, and opposite side receives light.During drilling machine work, main shaft drives counting scale and constantly rotates.Counting scale whenever rotates a circle, and its counting is just passed certain number of times (being hole or breach number uniform on the counting scale) by light with hole or breach, forms the light pulse of some.This light pulse number is electric signal by conversion of photoelectric sensor and sends digital indicator to and control circuit, finally is displayed on the digital indicator.Counting can be one with hole or breach, and photoelectric sensor whenever detects a light pulse and is a commentaries on classics; Counting also can be N (N is a positive integer) that is uniformly distributed along the circumference with hole or breach, and photoelectric sensor whenever detects N light pulse and is a commentaries on classics.
Digital indicator can be group of four figures tube display or four LCD.Charactron display and liquid crystal display displays are clear, low price, and effect is fine.The rotating speed of general drilling machine mostly is 1,000 most more to be changeed, enough with four demonstrations, very reasonable.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of can clear, accurately, immediately show the particularly numeric display unit of the bench drill rotating speed of stepless change drilling machine rotating speed of drilling machine.It can be widely used on bench drill and other drilling machine.

Embodiment
The numeric display unit of 1. 1 kinds of bench drill rotating speeds of embodiment.As Fig. 1～shown in Figure 3.It is installed in by base, column 1, selective headstock 2, motor 3, main shaft 4, rack sleeve 5, drill chuck 6, driving pulley 7, is installed on the drilling machine that driven pulley 8, belt wheel cover 9 and motor switch 10 on the main shaft 4 form.At least comprise the counting scale 11 that is fixed on below the driven pulley 8, be fixed on sensor frame 17 on the selective headstock 2, be fixed on the digital indicator 14 and the control circuit thereof that are installed in selective headstock 2 fronts that straddle the outer intermarginal photoelectric sensor 12 of counting scale 11 on the sensor frame 17, be connected with photoelectric sensor 12 with lead 13.Have a counting on the outer rim of counting scale 11 and use hole 15.Digital indicator 14 is a group of four figures display.
The numeric display unit of 2. 1 kinds of bench drill rotating speeds of embodiment.As shown in Figure 4.Have counting breach 16 on the outer rim of its counting scale 11.Digital indicator 14 is four LCD.Surplus with embodiment 1.
Embodiment 1～2 can clear, accurately, immediately show the particularly rotating speed of stepless speed change bench drill of bench drill.It can be widely used on bench drill and other drilling machine.
Claims (2)
1. the numeric display unit of a bench drill rotating speed, it is installed in by base, column, selective headstock, motor, main shaft, rack sleeve, drill chuck, driving pulley, be installed in the driven pulley on the main shaft, on the drilling machine that belt wheel cover and motor switch are formed, it is characterized in which comprises at least the counting scale that is fixed on below the driven pulley, be fixed on the sensor frame on the selective headstock, be fixed on and straddle the outer intermarginal photoelectric sensor of counting scale on the sensor frame, with digital indicator that is installed in the selective headstock front and the control circuit thereof that lead is connected with photoelectric sensor, have counting on the outer rim of counting scale with hole or breach.
