Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The boring drilling machine of a kind of grinder, as shown in Figure 1, comprise drill-bit installing seat 1, support 2, the motor 3 being installed on support 2, the transmission component be connected with motor 3 output shaft 4, transmission component outside are provided with protective cover 5, sliding is arranged at sleeve 7 on support 2 in installing hole 6, is rotatably installed in main shaft 8 in sleeve 7 and drive sleeve 7 along installing hole 6 feed arrangement 8 in axial sliding; Described main shaft 8 one end is connected with transmission component, and the other end arranges drill-bit installing seat 1.
Wherein, described transmission component comprises the geared sleeve 10 being arranged on travelling gear 9 on motor 3 output shaft 4 and be arranged on support 2 by bearing and the idle wheel 11 engaged with the two respectively between travelling gear 9 with geared sleeve 10; Described geared sleeve 10 is coaxial with installing hole 6.
In actual production, be preferably fixed on support 2 by axle of carrier pulley 19 end installing described idle wheel 11, like this, idle wheel 11 is firmly located, and ensure that the reliable and stable of this drilling machine transmission process.
Wherein, feed arrangement 8 comprises the driven wheel 13 of hand lever 12 and the connection of hand lever 12 end as described in Figure 3; As shown in Figure 2, described sleeve 7 is provided with the straight-tooth section 14 engaged with this driven wheel 13.It should be noted that, driven wheel 13 is by being arranged on flat key and the hand lever 12 of hand lever 12 end, and easy accessibility, stable connection is reliable.Hand lever 12 differs from the one end of installing driven wheel 13 can arrange handle 20, is more convenient for the operation of rotation manual bar 12.
