Abstract
The utility model discloses a main spindle box of a radial drilling machine. The main spindle box consists of an input shaft, an output shaft, a transition shaft, a variable-speed shaft and a variable-speed control mechanism, wherein transmission gears are respectively arranged on the input shaft, the output shaft and the transition shaft, a quintuplet sliding gear which can realize five-speed change is arranged on the variable-speed shaft, and a control lever of the variable-speed control mechanism is arranged on the side of the main spindle box. The automatic feed rate of the main spindle box is generated through one speed change of the quintuplet sliding gear, and the variable-speed control mechanism is arranged on the side of the main spindle box, so that the main spindle box has the advantages of simplicity in structure, reliability in performance, convenience in operation, low cost and the like.
Description
Technical field
The utility model relates to a kind of machine tool component, especially a kind of main spindle box of radial drilling machine.
Background technology
The main spindle box of present domestic radial drilling machine, the selection of its main shaft automatic feed quantity will realize by an edge cam shifting fork mechanism usually, the manufacturing of cam mechanism is complicated, cost is higher, only be provided with the tetrad shifting slide gear that to realize four-speed gear shift on the variable-speed shaft, and the gear change of this mechanism partly is arranged on the front of main spindle box, and inconvenience operates.
The utility model content
The purpose of this utility model is to provide a kind of radial drilling machine main spindle box simple in structure, easy to operate, lower-cost.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of main spindle box of radial drilling machine is comprised of power shaft, output shaft, transition axis, variable-speed shaft and selector gear.Be respectively equipped with described travelling gear on described power shaft, output shaft, the transition axis, described variable-speed shaft is provided with the 5-linked shifting slide gear that can realize five grades of speed changes, and the action bars of described selector gear is arranged at the side of main spindle box.
Described variable-speed shaft is provided with the 5-linked shifting slide gear.
The utility model is compared with existing rocking arm bed, only produce through a speed change because automatic feed quantity passes through 5-linked shifting slide gear axle group, and operating mechanism is arranged at the side of main spindle box body, thereby have simple in structure, dependable performance, easy to operate, low cost and other advantages.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is schematic side view of the present utility model.
The specific embodiment
6 are provided with power shaft 4, excess axle 5, variable-speed shaft 8, variable-speed shaft 16, output shaft 15 and selector gear in the main spindle box body of the present utility model.Power shaft 4 is provided with gear 1 and gear 3, transition axis 5 is provided with gear 2 and gear 7. variable-speed shafts 8 are provided with gear 18, gear 17, gear 10 and gear 9, gear 17,18 and gear 9,10 be respectively duplicate gear, variable-speed shaft 16 is provided with the 5-linked shifting slide gear 11,12,13,14 that can realize five grades of speed changes, also is provided with gear 19 on the variable-speed shaft 16.Output shaft 15 is provided with gear 20. above-mentioned all travelling gears and axle is the key transmission, axle 4,5,8,16,15 all support with main spindle box body 6 on.
Selector gear is made of handle 23, fork 22, fork bar 21.Handle 23 is arranged at the front of main spindle box body 6.Fork 22 places between the 5-linked shifting slide gear 12,13 by fork bar 21.Any a pair of gear train is different meshing in the 5-linked shifting slide gear group, can obtain five kinds of obstructed output speeds.When needing speed change, turning handle 23 promotes fork 22 by lever principle, obtaining the meshing of a pair of gear train required in the 5-linked shifting slide gear group, thereby obtains required output feed speed.
The above is embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model application range, feature and principle change or modify, is included in the utility model patent claim.
