Abstract
The utility model discloses a flexible gear positioning tool. The flexible gear positioning tool comprises a mandrel with a taper surface, a reduction sleeve arranged on the taper surface of the mandrel in a sleeved mode, and a pressing mechanism used for pressing the reduction sleeve to enable the reduction sleeve to slide axially along the mandrel. According to the flexible gear positioning tool, a flexible gear cylinder can be fixed in an expansion mode based on the expansion sleeve principle, then a whole flexible gear can be positioned, the positioning accuracy is high, the flexible gear can be effectively prevented from deforming in the machining process, the machining quality of the flexible gear can be improved, and therefore the product can meet design requirements.
Description
Technical field
The utility model relates to a kind of frock, relates in particular to a kind of flexbile gear positioning tool.
Background technology
It is large that harmonic drive has gearratio, volume is little, lightweight, precision is high, the advantages such as return difference is little, be widely used in aviation, space flight, on the equipment such as boats and ships, harmonic drive mechanism is generally by the flexbile gear that is provided with external toothing, the rigid wheel and the wave producer that are provided with ring gear form, can utilize flexbile gear when rotating, to produce continuous modification and the motion of rigid wheel generation side set, realize and slowing down and transmission, wherein flexbile gear consists of end cap and flexbile gear cylinder, flexbile gear cylinder is thin-walled parts, can deform, end cap and flexbile gear cylinder mostly are integrative-structure, flexbile gear location difficulty in process, easily distortion, be difficult to reach designing requirement.
Therefore, for addressing the above problem, need a kind of flexbile gear positioning tool, for flexbile gear is located reliably, improve positioning precision, prevent that in process, flexbile gear deforms, improve flexbile gear crudy, to reach designing requirement.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of flexbile gear positioning tool, can locate reliably flexbile gear, and positioning precision is high, can effectively prevent that in process, flexbile gear deforms, and improves flexbile gear crudy, makes product reach designing requirement.
Flexbile gear positioning tool of the present utility model, comprise be provided with tapering face mandrel, be set in the drill holder of mandrel tapering face and make it along mandrel hold-down mechanism in axial sliding for compressing drill holder;
Further, described hold-down mechanism comprise clamp nut and be supported in clamp nut and drill holder between lining; Described mandrel front end extends axially the installation shaft that is formed for installing clamp nut and lining; In described installation shaft, corresponding clamp nut is provided with external screw thread;
Further, described lining is step nested structure, its endoporus and installation shaft interference fits, and its small end outside diameter is consistent with flexbile gear end cap central bore aperture;
Further, the large end end face of described lining is provided with for being supported in the ring platform of drill holder.
The beneficial effects of the utility model are: flexbile gear positioning tool of the present utility model, utilized the principle of expansion set, can carry out swelling to flexbile gear cylinder fixes, and then the location of realization to whole flexbile gear, positioning precision is high, can effectively prevent that in process, flexbile gear deforms, be beneficial to and improve flexbile gear crudy, make product reach designing requirement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the flexbile gear positioning tool of the present embodiment, comprise be provided with tapering face mandrel 1, be set in the drill holder 2 of mandrel 1 tapering face and make it along mandrel 1 hold-down mechanism in axial sliding for compressing drill holder 2; Drill holder 2 peripheries are provided with anti-skidding striped, anti-skidding striped is by forming in drill holder 2 periphery machined grooves, groove comprises the cannelure (not shown) arranging around drill holder 2 excircle directions, easy to process, directly processing on drill holder 2 in the prior art; Described cannelure is axially evenly arranged a plurality of along drill holder 2; Groove also comprises the straight trough (not shown) axially arranging along drill holder 2; Described straight trough is evenly arranged a plurality of along drill holder 2 excircle directions, by cannelure and straight trough, interlocked and be combined to form netted anti-skidding striped, and non-skid property is good, can improve the positioning precision of flexbile gear 6.
In the present embodiment, described hold-down mechanism comprise clamp nut 3 and be supported in clamp nut 3 and drill holder 2 between lining 4; Described mandrel 1 front end extends axially the installation shaft 5 that is formed for installing clamp nut 3 and lining 4; In described installation shaft 5, corresponding clamp nut 3 is provided with external screw thread; Mandrel 1 front end refers to one end that on mandrel 1, corresponding tapering face cone point points to, reasonable in design, and each modular construction is simple, easily processing and fabricating; The corresponding normal line (not shown) that is provided with on clamp nut 3 and mandrel 1, the position of normal line is rationally set, while making clamp nut 3 screw in certain tooth in installation shaft 5 to count, normal line on normal line on clamp nut 3 and mandrel 1 over against time be position that the tension force of flexbile gear is of moderate size, the size of convenient operation and unified tension force.
In the present embodiment, described lining 4 is step nested structure, its endoporus and installation shaft 5 interference fits, and its small end outside diameter is consistent with flexbile gear 6 end cap central bore apertures; Small end refers to step cover relatively little one end of external diameter, and large end refers to step cover relatively large one end of external diameter; During clamping flexbile gear 6, can make lining 4 small ends be stretched out by flexbile gear 6 end cap central bore, can carry out radial location to flexbile gear 6 end caps, flexbile gear 6 positioning precisions and position stability more can be improved in swelling location in conjunction with 2 pairs of flexbile gear cylinders of drill holder, effectively prevent that flexbile gear 6 from deforming in process.
In the present embodiment, the large end end face of described lining 4 is provided with for being supported in the ring platform of drill holder 2, ring platform radially inner side hollow space forms the bit space that allows of being stepped down in tapering face end, can guarantee the axial promotion function of 3 pairs of drill holders 2 of clamp nut, avoids constructive interference.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
