The specific embodiment
As shown in Figure 1, drilling machine comprises base 1, column 2, workbench 4, main spindle box 3 and motor D, and column 2 is fixed on the base 1, and workbench 4 is socketed on the column 2, and can be beneficial to workpiece is operated along column 2 oscilaltions.Main spindle box 3 is fixed on the column 2, and main shaft 6 is arranged in the main spindle box 3.The sidepiece of main spindle box 3 has handle 5, and the sidepiece of main shaft 6 connects with handle 5, and by turning handle 5, can drive the bottom oscilaltion of main shaft 6.The lower end of main shaft 6 is a drill chuck 11, is used for clamping drilling bit or screw tap.
As shown in Figure 1, the upper end of main shaft 6 connects with the rotating shaft of motor D by belt pulley 12 and belt 8.In the present embodiment, the upper end of main shaft 6 is provided with a cone pulley 12, and the rotating shaft of motor D is provided with a cone pulley 12 that direction is opposite, and these two cone pulleies 12 connect by belt 8.Because the belt grooves of some roads various outer diameter is arranged on the cone pulley 12, so by regulating the position of belt 8 in belt grooves, can change the rotating ratio of motor D and main shaft 6, regulate the rotating speed of main shaft 6 and drill chuck 11, make this drilling machine carry out tapping or boring with a suitable rotating speed.
As shown in Figure 1, the travel switch J in the circuit for controlling motor is located at the sidepiece of main spindle box 3.As shown in Figures 2 and 3, two travel switch J are set up in parallel in the present embodiment, and the button 9 of travel switch J is positioned at the edge of rotating shaft 50 on the handle 5.Simultaneously, on the edge of arm pivot post 50, be provided with two projections 51,52 that correspond respectively to above-mentioned two travel switch J buttons 9.
As shown in Figure 4, the circuit for controlling motor of this semi-automatic speed governing tapper mechanism comprises a main A.C. contactor JC, one pair of A.C. contactor SC and two travel switch J.The normally open contact switch of main A.C. contactor JC is serially connected with respectively between terminals X, Y, the Z of three phase mains A, B, C and motor D, and the normally open contact switch of paying A.C. contactor SC is serially connected with respectively between terminals Z, the Y of three phase mains A, B, C and motor D, the X.When handle 5 is in initial position, on the button 9 of this trip switch J1, make the first travel switch J1 be in off-state corresponding to projection 51 roof pressures of the first travel switch J1.Therefore, when not pulling the handle 5 of drilling machine, no current passes through on the circuit for controlling motor, and motor D can not be rotated.
When this drilling machine is operated, at first to pull handle 5, utilize the projection 51 at handle 5 rotating shafts 50 edges to leave the first travel switch J1 and make its conducting.Like this, electric current through the first travel switch J1, the second travel switch J2, main A.C. contactor JC coil with after paying A.C. contactor SC normally closed interlock switch, forms a loop to power supply B by power supply C.Because main A.C. contactor JC coil electricity, so three phase mains can rotate motor D by entering the terminals of motor D behind the main A.C. contactor JC normally open contact switch, and the screw tap of drive main shaft 6 and main shaft 6 lower ends rotates together, and workpiece is carried out tapping.Pulling handle 5, after making tapping reach the desired degree of depth, will go to button 9 places of the second travel switch J2 in handle 5 rotating shafts 50 corresponding to the projection 52 of the second travel switch J2, also change with regard to the state that makes the second travel switch J2, its normally closed contact disconnects, and the normal opened contact conducting.Therefore, the current loop by these two travel switch J changes, electric current by the normal opened contact of the second travel switch J2 coil and the normally closed interlock switch of main A.C. contactor JC through paying A.C. contactor SC after, form a loop.Like this, the coil blackout of main A.C. contactor JC and pay the coil electricity of A.C. contactor SC is so three phase mains can make the motor D rotation by paying the terminals that enter motor D behind the A.C. contactor SC normally open contact switch.Because power line by paying A.C. contactor SC and the wiring phase place of motor D and opposite by the wiring phase place of main A.C. contactor JC so motor D will be reversed, make the screw tap counter-rotation on the drill press spindle 6, promptly refund automatically.
In this drilling machine, because the rotational angle of handle 5 is directly proportional with the lifting distance of drill chuck 11, so the degree of depth that can regulate tapping by the position of mobile second projection 52.
As shown in Figure 4, in this circuit for controlling motor, also be provided with change-over switch K and master switch HK.Except travel switch J, other element in the circuit for controlling motor all is positioned in the control box.In the present embodiment, control box is located on the main spindle box 3 side locations relative with handle 5.The profile of control box as shown in Figure 5, master switch HK and change-over switch K are contained in its surface.Have only when master switch HK is in the state of conducting, could carry out various operations this drilling machine.
As shown in Figure 4, change-over switch K then is used for this drilling machine and is in the tapping state and is in conversion between the bore state.When change-over switch K conducting, this drilling machine will be in the tapping state, and its course of work as mentioned above.After change-over switch K disconnected, this drilling machine just was in bore state.Particularly, at first pull handle 5, motor D is rotated, drive main shaft 6 and drill chuck 11 and rotate the operation that drilling machine is holed together.When the degree of depth of bit drills setting extremely, the projection 52 of the second travel switch J2 goes to button 9 places of the second travel switch J2, make the normal opened contact conducting of the second travel switch J2, but because change-over switch K is in off-state, so the coil of the coil of main A.C. contactor JC and pair A.C. contactor SC all can not be switched on, that is to say that three phase mains can't enter the terminals of motor D by main A.C. contactor JC, the SC of paying, motor D shuts down.Like this, as long as, make drill bit withdraw from workpiece, promptly finish drilling operation to workpiece along pulling handle 5 in the other direction.
