Description

The frock clamp of gear system tooth
Technical field
The utility model relates to a kind of frock clamp of Gear Processing, is specifically related to a kind of frock clamp that can be used for the gear system tooth of gear hobbing and shaving.
Background technology
At present, the motorcycle initiating gear need carry out clamping by the frock clamp that is installed on the gear-hobbing machine when the system tooth, the frock clamp of clamping starter receiver comprises mandrel 4, bearing 2, bearing is fixedly connected on the gear-hobbing machine rotary table 1, the workpiece 5 of need processing is enclosed within on the mandrel also by locking nut 6 lockings, mandrel one end passes the through hole that is provided with on the bearing and passes through nut 3 fixedlys connected with bearing, and the mandrel other end holds out against (as shown in Figure 1) by post top 7.Because the required precision of motorcycle initiating gear reaches eight grades, above-mentioned frock clamp generally all needs combined high precision gear-hobbing machine and hobboing cutter with slower feed, processes by the mode of rolling two cuttves, just can reach required precision.The processing mode of the said equipment, too high to cutter, equipment and cutter installation requirement, when not reaching this requirement, the frequent out-of-size of the profile of tooth after the processing, roughness does not reach requirement, and easily the flank of tooth is pulled; In the process, also need be equipped with frequent checks of profile of tooth instrument voluntarily, it is very loaded down with trivial details to operate; In addition, as the precision of hobboing cutter, require inspection machine more, the inspection machine of hobboing cutter generally is reluctant to dispose in order to save cost by producer, specifically by what reason is caused for the profile of tooth out-of-size, is difficult to investigate.In addition, workpiece such as need through the said equipment gear hobbing are reprocessed by the shaving that gear shaving machine improves precision, just have only the workpiece that is enclosed within on the mandrel is pulled down successively, then the single-piece clamping workpiece is carried out shaving on the frock clamp of gear shaving machine, adopt this mode can only the single-piece shaving on gear shaving machine, efficiency in shaving is lower, and the workpiece variation is easily overproof; And adopt and to disassemble from the gear-hobbing machine frock the mandrel that is with workpiece of existing gear-hobbing machine frock clamp is whole, be installed in shaving on the gear shaving machine, this mode is because mandrel location transformation of criterion, the workpiece variation is easily overproof, the mounting or dismounting of frock are proofreaied and correct very loaded down with trivial details, and equally machining accuracy are impacted.Therefore existing gear-hobbing machine frock clamp working (machining) efficiency in gear system tooth process quality low, product is also relatively poor, is unfavorable for improving the machining accuracy of gear.
Summary of the invention
The purpose of this utility model is, a kind of frock clamp of gear system tooth is provided, by it processed workpiece is processed with bigger feed, and the mandrel integral body that is with workpiece can be unloaded to reinstall to and carry out fine finishining on the gear shaving machine, precision, efficient and the quality of starter receiver processing are improved, and processing cost also is reduced.
The purpose of this utility model is achieved like this: a kind of frock clamp of gear system tooth, comprise bearing, mandrel, mandrel is a multidiameter, its small end be provided with threaded journal, bearing is provided with through hole, the top small end of a band multidiameter passes the through hole of bearing, the top shaft shoulder is limited in bearing, and lock by nut, a fixedly connected annular dial on the bearing, top center point passes the circle center hole of annular dial, fixedly connected heart folder on the annular dial, the axle journal of the big end of mandrel passes the hole of heart folder, by the top centre bore that withstands the mandrel end face fixed in, mandrel is circumferentially located by the screw that radially is provided with on the heart folder, bearing is fixedly connected on the gear-hobbing machine rotary table, the centre bore of mandrel small end axle journal end face and post is top offsets holds out against mandrel between at post top and band multidiameter top.
Adopted such scheme, mandrel is circumferentially located by the screw that radially is provided with on the heart folder, bearing is fixedly connected on the gear-hobbing machine rotary table, and the internal point of mandrel small end axle journal end face and post is top offsets holds out against mandrel between at post top and band multidiameter top.Use the advantage of above-mentioned frock clamp to be: at first need not be too high to the reconditioning requirement of hobboing cutter and hobboing cutter, and can pass through bigger feed, and workpiece is carried out roughing, can shorten process time, improve working (machining) efficiency; Secondly, the required precision to hobboing cutter during owing to roughing reduces, and need not dispose measuring equipment for hobboing cutter, to save manufacturing cost; Be to put a plurality of workpiece the mandrel last time to carry out gear hobbing simultaneously once more, make production efficiency improve.After gear hobbing is finished, the mandrel integral demounting that is with workpiece can be got off directly to be installed to and carry out shaving on the gear shaving machine, the location benchmark of mandrel and workpiece can be maintained in the unloading process, be installed in workpiece variation on the mandrel in allowed band, its machining accuracy can be affected, therefore, efficiency in shaving is not only high, and the shaving precision also is improved, and obtains meeting the starter receiver of required precision, and production cost is minimized simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
