Abstract
The utility model discloses a steel rail boring machine drill bit quick change device which comprises a boring machine main spindle 1, characterized in that a binding ring 2 is fixedly connected on the boring machine main spindle 1, the front end of the main spindle 1 is arranged with a fixture 3 that connected with the main spindle 1 through a key 6, a compression spring 4 surrounded the main spindle 1 is arranged between the fixture 3 and the binding ring 2, a groove 5 is arranged on the front of fixture 3, a hole 8 is arranged on the main spindle 1, the hole 8 is equipped with jamming ball lumps 7. The utility model has the advantages of quick change of the drill bit and high efficiency.
Description
Technical field
The utility model relates to a kind of rail bonding drill drill bit handler, especially a kind of drill bit fast assembling and disassembling device.
Background technology
At present, the rail bonding drill drill bit locking device that generally uses is at drill bit and main shaft junction one screens bolt to be set on the market, though this structure is simple, but impracticable, mainly show two aspects: the one, dismounting is slow, because the drilling machine anchor clamps are when the folder rail, the spacing of drill bit and rail is very little, therefore when bit change more, must be with anchor clamps Panasonic from the rail, so more bit change need be spent the time of growing; On the other hand, if foramen primum has not bored, drill bit damages, still to continue to bore foramen primum after this means bit change, will be during owing to replacing with anchor clamps from rail Panasonic, when clamping rail so once more, so not only lost time but also error easily in the hole that must more accurate again anchor clamps drill bit has not been bored.
Technology contents
The purpose of this utility model is to provide a kind of drill bit fast assembling and disassembling device, can effectively overcome the shortcoming of prior art.
The purpose of this utility model is achieved through the following technical solutions, it comprises the drilling machine main shaft, it is characterized in that: on the drilling machine main shaft, be fixedly connected with snap ring, at front-end of spindle one chuck is set, be connected by key between this chuck and the main shaft, a stage clip around main shaft is set between this chuck and the snap ring, be provided with groove in the front portion of chuck, on main shaft, also be provided with porosely, the screens steel ball is installed in the hole.
The utility model is owing to adopt technique scheme, when needs more during bit change, only need to promote chuck, the extruding stage clip, simultaneously outwards extracting bad drill bit gets final product, after inserting green bit, unclamp chuck, the stage clip resilience, chuck extruding steel ball, green bit is clamped, and whole process need not unloaded the rail anchor clamps, and dismounting simultaneously is simply quick.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1-drilling machine main shaft, 2-snap ring, 3-chuck, 4-stage clip, 5-groove, 6-key, 7-screens steel ball, 8-hole, 9-drill bit.
The specific embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
The utility model comprises drilling machine main shaft 1, on drilling machine main shaft 1, be fixedly connected with snap ring 2, at main shaft 1 front end one chuck 3 is set, be connected by key 6 between this chuck 3 and the main shaft 1, one stage clip 4 around main shaft 1 is set between this chuck 3 and the snap ring 2, be provided with groove 5 in the front portion of chuck 3, on main shaft 1, also be provided with porosely 8, screens steel ball 7 is installed in the hole 8.When dismounting drill bit 9, only need to promote chuck 3, extruding stage clip 4, after when screens steel ball 7 enters chuck 3 grooves 5 positions, bad drill bit 9 can take off from main shaft easily, and install green bit 9 and get final product this moment, unclamp chuck 3 then, stage clip 4 resilient depression screens steel balls 7 are fixing with green bit 9.Whole dismounting process is very simple and need not to dismantle the rail anchor clamps.
Zong the above, Yu Xian You technology Xiang ratio, the utlity model has the fast and efficiently characteristics of Zuan head that change the outfit.
