Abstract
A small size table drill belongs to the table drill technological art, comprising a work platform, a standing pillar, a nose box, a motor, a drive structure, a main shaft and a drill fixture, a bear, a liner, a feed structure and an electric control system, wherein the motor is a single phase series excitation motor, the shaft of the motor is directly connected by a coupling, the coupling is equipped with fan vanes, the outer edge on the tail end of the motor is equipped with a flange, the upper end of a hole on the liner equipped on the nose box is equipped with a boss, a compress spring is equipped between the flange and the boss, the nose box is also equipped with a starting and stopping switch, a reducing switch, a sudden stop switch and an illuminating lamp, the sudden stop switch is positioned above the nose box, and the illuminating lamp is positioned below the nose box. The drive structure is simple, the speed adjusting is convenient, the knife withdrawing speed is fast, hand motion is not needed, and the knife withdrawing spring is not easy to be damaged. The utility model can be widely used for the drilling process in places of the family, the small mill and the like.
Description
Technical field
The utility model belongs to the bench drill technical field, more particularly relates to the improvement of the structure of small-sized bench drill.
Background technology
Existing bench drill mostly with motor through belt, cone pulley transmission mechanism drive shaft, again with the rotation of main shaft drives drill chuck and drill bit.This belt, the cone pulley kind of drive are complicated, need during speed change belt conversion in the different races of cone pulley is quite bothered, and need often to change the belt of rapid wear.During the boring feeding, need be rotated counterclockwise the feeding handle, drive feed gear wheel, drive the sleeve that has the tooth bar that meshes with feed gear wheel again and down move.When boring finishes to withdraw from drill bit, the feeding handle that then need turn clockwise in the other direction, it is reverse to drive feed gear wheel, drives the sleeve that has tooth bar again and up moves.This feeding mode is simpler, but its feeding, withdraws from all and to need manually, and rate of withdraw is slow.The bench drill that has installs torsion spring additional on feed mechanism, can drive with torsion spring during withdrawing.But the torsion of torsion spring is less, and is fragile.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides a kind of drive mechanism simple, and speed governing is convenient; Withdrawing speed is fast, do not need manually, and the non-damageable small-sized bench drill of withdrawing spring.
Summary of the invention
In order to achieve the above object, the utility model comprises workbench at least, is fixed on column on the workbench, is locked at head box on the column, is installed in the motor on the head box, the transmission mechanism, the main shaft that is connected with transmission mechanism and the drill chuck that are connected with the axle of motor, is contained in sleeve outside the main shaft, is engaged on the feed mechanism on the tooth bar of sleeve and is installed in electric control system on the head box with bearing holder (housing, cover).Motor is a single phase series motivated motor, and the axle of motor directly is connected with shaft joint with main shaft, has fan blade on the shaft joint.
The single phase series motivated motor starting torque is big, and mechanical property is soft, and speed governing is convenient.Be highly suitable for the utility model.Motor shaft and main shaft are quite simple with the direct-connected structure of shaft joint, have in fact saved transmission mechanism, and have improved transmission efficiency.Fan blade directly is fixed on the shaft joint, can cooling motor, save the cooling fan of motor.
The tail end outer rim of motor is equipped with flange, and the upper end in the hole of installing sleeve has boss on the head box.The compression spring is installed between flange and the boss.Boring is rotated counterclockwise the feeding handle during feeding, drives feed gear wheel, drives the sleeve that has with the tooth bar of feed gear wheel engagement again together with the down feeding of motor, drill chuck and drill bit, will compress spring simultaneously and compress.When boring finishes to withdraw from drill bit, only need release handle, under the tension force effect of compression spring, just motor, drill chuck and drill bit can be resetted and return.Withdrawing is very simple, and speed is fast, and does not need manually.Compression spring reliable operation, not fragile.
Guard's valve, speed-regulating switch, emergency stop switch and illuminating lamp also have been installed on the head box.Emergency stop switch be positioned at head box above.In the time of need stopping in emergency, press very convenient.Illuminating lamp be positioned at head box below, be convenient to the illumination, work.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of drive mechanism simple, and speed governing is convenient; Withdrawing speed is fast, does not need manually withdrawing spring reliable operation, non-damageable small-sized bench drill.It can be widely used in the boring processing in places such as family, individual workship.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment 1.A kind of small-sized bench drill, it comprises workbench 1, column 2, head box 3, motor 4, transmission mechanism, main shaft 5 and drill chuck 6, bearing 7, sleeve 8, feed mechanism and electric control system.Motor 4 is a single phase series motivated motor.The axle 9 of motor 4 directly is connected with shaft joint 10 with main shaft 5, has fan blade 11 on the shaft joint 10.The tail end outer rim of motor 4 is equipped with flange 12, and the upper end in the hole of installing sleeve 8 has boss 13 on the head box 3, and compression spring 14 is installed between flange 12 and the boss 13.Guard's valve 15, speed-regulating switch 16, emergency stop switch 17 and illuminating lamp 18 also have been installed on the head box 3.Emergency stop switch 17 be positioned at head box 3 above, illuminating lamp 18 be positioned at head box 3 below.
Embodiment 1 drive mechanism is simple, and speed governing is convenient; Withdrawing speed is fast, does not need manually, and the withdrawing spring is not fragile.It can be widely used in the boring processing in places such as family, individual workship.
