Abstract
The utility model discloses a kind of lining fixture of drill centers, it comprises and is enclosed within machining shaft (1) lining outward (2), be enclosed within lining (2) overcoat outward (3), inlay the guiding drill bushing (4) being arranged on overcoat (3) top, be arranged on the centre drill (5) in guiding drill bushing (4); Described overcoat (3) is provided with first trip bolt (6) of stationary bushing (2).The lining fixture of the drill centers that the utility model provides, reasonable in design, easy to operate, clamp reliable and stable, can be used for the larger different size of diameter shaft-like workpiece clamping, can keep drilling machine axis and shaft-like workpiece section perpendicular, working (machining) efficiency is higher, and the axle centre bore precision processed is high, and quality is high, practical.
Description
Technical field
The utility model relates to a kind of mechanical device, is specifically related to a kind of lining fixture of drill centers.
Background technology
Lathe when processing work, as working shaft-like workpiece centre bore.The diameter of different shaft-like workpiece is 40 ~ 80mm, length 1000mm, and the diameter due to axle is greater than lathe spindle internal taper hole diameter, shaft extension cannot be entered in taper hole, so centering is more difficult on lathe.Machining center hole on rocking arm lathe is adopted in prior art.But because drilling machine axis is not easily perpendicular with shaft-like workpiece section, on inclined-plane, drill centers is just not easily being beaten, and greatly affects the quality of processing.
Therefore, on the basis of existing technology necessary, research and develop a kind of reasonable in design, easy to use, clamp reliable and stable, and carry out the lining fixture of drill centers after can be used for diameter larger axis class piece-holder.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, a kind of reasonable in design is provided, easy to use, clamp reliable and stable, and can be used for diameter larger axis class piece-holder, can keep drilling machine axis and shaft-like workpiece section perpendicular, the lining fixture of the drill centers that working (machining) efficiency is higher.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A lining fixture for drill centers, it comprises the lining be enclosed within outside machining shaft, is enclosed within the overcoat outside lining, inlays the guiding drill bushing being arranged on overcoat top, is arranged on the centre drill in guiding drill bushing; Described put the first trip bolt being provided with stationary bushing outward.By screwing the first trip bolt, lining is locked.
Preferably, the lining fixture of above-described drill centers, described lining and put outward and offer screw hole, the second trip bolt locks machining shaft through after the screw hole of lining and overcoat.
Preferably, the lining fixture of above-described drill centers, described lining inwall offers groove.
As being more preferably scheme, the lining fixture of above-described drill centers, described lining inwall offers toroidal cavity.It is the local distortion's part going for shaft blank may exist that the utility model offers toroidal cavity on lining inwall.Facilitate the insertion of shaft-like workpiece and fix.
Preferably, the lining fixture of above-described drill centers, the internal diameter of described lining is 40 ~ 80mm.May be used for the axle gripping different-diameter size.
The lining fixture of the drill centers that the utility model provides, during actual use, axle to be processed is inserted in lining, then by the first trip bolt, lining is locked, and lock machining shaft passed the screw hole of lining and overcoat by the second trip bolt after.Then carry out drill centers by the centre drill in guiding drill bushing to the axle gripped, operation is very easy.
Beneficial effect: compared to the prior art the lining fixture of the drill centers that the utility model provides has the following advantages:
The lining fixture of the drill centers that the utility model provides, reasonable in design, easy to operate, clamp reliable and stable, can be used for the larger different size of diameter shaft-like workpiece clamping, can keep drilling machine axis and shaft-like workpiece section perpendicular, working (machining) efficiency is higher, and the axle centre bore precision processed is high, and quality is high, practical.
Accompanying drawing explanation
The structural representation of the lining fixture of the drill centers that Fig. 1 provides for the utility model.
Fig. 2 is the cross section structure schematic diagram along A-A direction.
