Detailed Description

The principles and features of the present invention will be described with reference to fig. 1 to 5, which are provided for illustration only and are not intended to limit the scope of the present invention.

A multi-station drilling machine comprises a shell 1, a driving shaft 2, a driving gear 3, two driven shafts 4, two driven gears 5 and two fixing sleeves 6. One end of the driving shaft 2 is connected with the driving gear 3, and the other end is connected with a driver (not shown in the figure). The driver can be a servo motor or a hydraulic motor, and the driver can drive the driving gear 3 to rotate in the inner cavity of the shell 1 to form a driving transmission system. The driven shaft 4, the driven gear 5 and the fixed sleeve 6 form a set of driven transmission system. The two driven gears 5 are symmetrically distributed on two sides of the driving gear 3. The upper half part of the driven shaft 4 is connected with a driven gear 5, and the lower half part of the driven shaft 4 is rotationally connected with a fixed sleeve 6. The driven gear 5 is in meshing transmission with the driving gear 3, and the bottom of the driven shaft 4 is connected with a drill bit 7. The whole transmission system comprises the following processes: the driver drives the driving shaft 2 to rotate, the driving shaft 2 drives the driving gear 3 to rotate, the driving gear 3 drives the driven gear 5 to rotate, the driven gear 5 drives the driven shaft 4 to rotate, and the driven shaft 4 drives the drill bit 7 to complete the drilling process. The fixing sleeve 6 is connected with the shell 1 in a sliding mode and can be fixed relative to the fixing sleeve 6. The fixed sleeve 6 can drive the driven shaft 4 to move upwards or downwards in a sliding mode, so that the relative height of the drill bit 7 can be adjusted, and holes with different depths can be machined.

Casing 1 includes upper portion 8, middle part 9 and lower part 10, upper portion 8, middle part 9 and upper portion 10 are fixed connection in proper order from top to bottom. A first bearing 11 is connected in the upper part 8, and the driving shaft 2 is connected with the first bearing 11. The drive shaft 2 is connected in rotation to the housing 1 via a first bearing 11. The lower part 10 is provided with guide holes 12, the guide holes 12 correspond to the fixing sleeves 6 one by one, and the fixing sleeves 6 are connected with the guide holes 12. Specifically, the guiding hole 12 is provided with a transmission internal thread, the fixing sleeve 6 is provided with an external thread, and the fixing sleeve 6 forms a sliding connection with the housing 1 through the matching of the transmission internal thread and the transmission external thread. When drilling, the axial force that drill bit 7 received is transmitted to on transmission internal thread and the transmission external screw thread to make fixed cover 6 lock, guarantee fixed cover 6 and casing 1 relatively fixed.

The top of driven shaft 4 is connected with locking nut 13, the top of driven shaft 4 still is connected with backing plate 14, backing plate 14 is circular, and sets up with driven shaft 4 is coaxial, backing plate 14 sets up in the below of last locking nut 13. The bottom of the harness 6 is provided with a flange 15, the harness 6 being slidable up to the bottom of the housing 1. The backing plate 14 serves as a lower limit and the flange 15 serves as an upper limit. When the fixed sleeve 6 slides upwards to make the flange 15 contact with the bottom surface of the shell 1, the driven shaft 4 rises to the maximum position; when the fixing sleeve 6 is slid down to bring the pad 14 into contact with the top surface of the driving gear 3, the driven shaft 4 is lowered to the maximum position.

A second bearing 16 is arranged in the fixed sleeve 6, and the driven shaft 4 penetrates through the fixed sleeve 6 and is connected with the second bearing 16. The driven shaft 4 is connected in rotation to the fixed sleeve 6 by means of a second bearing 16. Under the action of the second bearing 16, the driven shaft 4 can move up and down along with the fixed sleeve 6 and can rotate relative to the fixed sleeve 6.
