Background technology:
Gear-hobbing machine is most widely used a kind of lathe in the gear cutting machine, machinable straight-tooth, helical gears on gear-hobbing machine, but also machining worm wheel, sprocket wheel etc.; Be applicable in batch, small quantities of single-piece production cylindric spiral gear and worm gear of reaching, still but rolling cut certain parameter scope spends strong, easy to adjust, reliable safety device and automatic lubricating system, as the frock clamp mechanism adopting, as: cutter one end is fixedly mounted on the cutter chuck, the other end does not have fixture, and the mandrel of workpiece suit is also fixed by the heart clamping, and its processing mode is to cutter, the installation requirement of equipment and cutter is higher, and need frequent detection in the process, existence is than mistake, and product quality is not easy to guarantee, the while troublesome poeration, inefficiency has influenced productivity effect.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of gear-hobbing machine frock clamp is provided, solved in the process higher to the required precision of cutter, equipment and cutter, also need frequent detection, product quality is not easy to guarantee, troublesome poeration, problems such as inefficiency have improved productivity effect.
The utility model is achieved through the following technical solutions:
A kind of gear-hobbing machine frock clamp, include gear-hobbing machine, it is characterized in that: be installed with annular base on the rotary table of described gear-hobbing machine, described annular base is provided with the guide groove that the cross section is a T shape, on the described annular base bearing is installed, on the described bearing bolt is installed, described bolt moves in T shape guide groove, realizes bearing position adjustments on annular base; On the described bearing mandrel is installed, described mandrel is a multidiameter, its small end is thread spindle up, described mandrel upper surface is provided with centre bore, it is top on the gear-hobbing machine cantilever of described rotary table top liftable to be installed, the described top mandrel top of being positioned at, and in the top centre bore that heads into the mandrel end face; The described gear-hobbing machine chuck the place ahead of fixing a cutting tool is equipped with axle bed, and hobboing cutter one end is installed on the cutter chuck, and the other end rotates and is installed in the axle bed.
Described a kind of gear-hobbing machine frock clamp, it is characterized in that: the suit processing work that cogs on the described mandrel, and fix by the nut that screws on its small end thread spindle, the described top mandrel top that is positioned at is fixed workpiece, described hobboing cutter is packed into behind the cutter chuck, the other end is fixed by annular sleeve, makes hobboing cutter more stable in process.
The utility model has the advantages that:
The utlity model has simple in structure, easy to use, do not need characteristics such as frequent detection, constant product quality, operating efficiency height, improved productivity effect, can be widely used in the gear teeth processing of industries such as automobile, motorcycle.
The specific embodiment:
A kind of gear-hobbing machine frock clamp, include gear-hobbing machine 1, be installed with annular base 3 on the rotary table 2 of described gear-hobbing machine 1, described annular base 3 is provided with radially T shape guide groove 4, on the described annular base 3 bearing 5 is installed, on the described bearing 5 bolt is installed, described bolt is motion in the guide groove 4 of T shape in the cross section, on the described bearing 5 mandrel 6 is installed, described mandrel 6 is a multidiameter, and its upper end is small end and is thread spindle, described mandrel 6 upper surfaces are provided with centre bore, liftable top 8, described top 8 is installed on the gear-hobbing machine cantilever 7 of described rotary table 2 tops is positioned at mandrel 6 tops, and top 8 head in the centre bore of mandrel 6 end faces; Described gear-hobbing machine 1 chuck 9 the place aheads of fixing a cutting tool are equipped with axle bed 10, between described axle bed 10 and the cutter chuck 9 hobboing cutter are installed; The suit processing work that cogs on the described mandrel 6, and fix by the nut that screws on its small end thread spindle.Hobboing cutter one end is held on the cutter chuck, and the other end rotates and is installed on the axle bed 10.
