Description
Technical field
The utility model belongs to mechanical field of locating technology, refers in particular to a kind of novel driving top.
Background technology
The development of clamp technology comes from user to machined precision and the higher requirement of working (machining) efficiency.Nowadays, in Machining of Shaft-type Parts, traditional clamping chuck mode can not meet user to part machining high-precision and high efficiency requirement, drives top advantage in Machining of Shaft-type Parts further obvious.Drive the top and top positioning workpieces of tailstock tool in top dependence Qi Shang center, driving moving tooth to embed workpiece end face makes it rotate with machine tool chief axis, can complete axle part cylindrical, grooved and screw thread processing, in turning milling center, also can once complete the processing of keyway and oilhole, thereby working (machining) efficiency significantly improves, axiality and position degree are more guaranteed, are applied to more and more widely turning, grinding and the gear hobbing processing of axial workpiece.
It is top that Chinese patent ZL200720106495.1 discloses a kind of driving, there is following defect in this technology: top being arranged in main body pilot hole, top 60 ° of tips must be through the moving tooth part of driver plate upper end, this structure makes main body targeting part and top 60 ° of tips exist larger distance, conventionally the top relative driver plate inner via hole of outer diameter of round spindle is less, conventionally rigidity is not strong, there is certain gap in top outer circular shaft and driver plate inner via hole, therefore in the time that top tip is subject to radial stress, due to the drag effect that do not lead, top by flexural deformation certain generation, directly affect the machining accuracy of workpiece.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, safe and reliable, and the driving that can position is accurately top.
The purpose of this utility model is achieved in that
A kind of novel driving is top, comprise main base and the driver plate that is fixedly mounted on main base upside, the upper surface of described driver plate is evenly provided with several moving teeth, moving tooth and driver plate are one-body molded, the center of driver plate forms axially extending bore, in axially extending bore, be provided with top, the inwall of described top cylindrical axial plane and driver plate axially extending bore is for being slidably matched, its fit tolerance is less than 0.01mm, in the Morse taper shank inner via hole of described main base, is provided with the spring spiro rod assembly of described top upwards jack-up.
Preferably, the corresponding end face of described driver plate and main base is respectively arranged with the ring flange of working in coordination, and two ring flanges connect by fastening bolt.
Preferably, on the flange of described driver plate, form central counterbore, on the flange of main base, form the cylinder that embeds described central counterbore.
Preferably, the sidewall of described main base has the Mohs conical surface matching with machine tool chief axis Morse's taper hole.
Preferably, described spring spiro rod assembly comprises spring, guide spiro rod, hex nut and setscrew nut; The shaft of described guide spiro rod is connected with hex nut through after setscrew nut; Described spring housing is contained on the shaft of guide spiro rod, nut and the hex nut location that is positioned respectively, the upper and lower two ends of spring, and making it can only be flexible along guide spiro rod direction; Described setscrew nut is screwed in the vertical core of main base, and top lower end is against on guide spiro rod.
The utility model compared to existing technology outstanding and useful technique effect is:
Driver plate of the present utility model is connected by ring flange with main base, its stable connection, driver plate and moving tooth are one-body molded, both can not produce displacement, the axially extending bore of described top cylinder cylindrical axial plane and driver plate is for being slidably matched, fit tolerance is less than 0.01, and driver plate and main base are connected to each other by their ring flanges separately, and stability and rigidity are higher like this.Therefore solved to a certain extent moving tooth and top while being subject to radial load, moving tooth and toply cause the workpiece of processing cannot meet the requirements of precision because producing radial missing; The shaft of guide spiro rod is connected with nut through after setscrew nut; Nut and the hex nut location that is positioned respectively, the upper and lower two ends of spring, making it can only be flexible along screw rod direction; Described setscrew nut is screwed in the vertical core of main base, and top lower end is against on guide spiro rod, is easy to adjust.
