Description

A kind of gear teeth clamp
Technical field
The utility model relates to a kind of to use when carrying out gear hobbing process to disc type gear, workpiece can be carried out quickly, The tooling of reliable location, belongs to technical field of mechanical processing.
Background technique
When carrying out gear hobbing process to disc type gear, the positioning mechanism of workpiece should have enough clamping forces and higher positioning Precision, to prevent workpiece from occurring to loosen under the action of hobboing cutter and deviate.Traditional localization method is positioned using larger gap Seam allowance is processed by dial gauge centering, the disadvantage is that alignment time is long and clamping force not can guarantee, is easy to appear workpiece and is loosened now As causing gear teeth axial deviation, not only reducing the processing quality of workpiece, and repeat centering and also affect adding for workpiece Work efficiency rate.Therefore it is very necessary for designing one kind and can carrying out quick, reliable location tooling to disc type gear part.
Utility model content
The purpose of this utility model is that aiming at the disadvantages of the prior art, a kind of gear teeth clamp is provided, to improve disk The processing quality and processing efficiency of type gear.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of gear teeth clamp, includes pedestal, mandrel, tensioner, tapered sleeve, pressing ring and opening pressure pad in composition, described Mandrel is fixedly connected by the way that the horizontal location disk of its lower end is arranged in pedestal, and mandrel upper end is threaded, the tensioner It is sleeved on mandrel and is located above positioning disk, the workpiece to gear hobbing is covered in the outside of tensioner, and the tapered sleeve is sleeved on mandrel On, the taper end of tapered sleeve downward and is inserted into tensioner, and butt end is compressed by the tensioner nut being spun on mandrel, the pressing ring and opening Pressure pad is placed sequentially on the workpiece to gear hobbing and the clamp nut by being spun on mandrel compresses.
The lower end of said gear gear-hobbing clamp, the tensioner is cooperated by positioning spigot and mandrel, and upper end is equipped with multiple Around the equally distributed longitudinal gap of mandrel, be equipped on the inside of upper end with the matched conical surface of tapered sleeve, outside be equipped with it is multiple with to gear hobbing The corresponding Contact Tooth of workpiece, the Contact Tooth are uniformly distributed around axis of workpiece.
Said gear gear-hobbing clamp, the positioning disk of the mandrel and between the workpiece of gear hobbing be equipped with support sleeve.
Said gear gear-hobbing clamp is connected between the lower end and mandrel of the tensioner by fastening screw.
Said gear gear-hobbing clamp, the tensioner nut and clamp nut are band shoulder nut.
Said gear gear-hobbing clamp, transition fit between the tapered sleeve and mandrel.
The utility model is positioned using the workpiece that the tensioner and tapered sleeve that are assembled on mandrel treat gear hobbing, not only may be used To guarantee the positioning accuracy and clamping force of workpiece, workpiece is avoided loose phenomenon occur, and easy to operate, locating speed is fast, from And effectively increase the processing quality and processing efficiency of disc type gear.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is tapered sleeve structural schematic diagram;
Fig. 3 is opening pressure pad structural schematic diagram;
Fig. 4 is tensioner structural schematic diagram;
Fig. 5 is core shaft structure schematic diagram.
Each label in figure are as follows: 1, pedestal;2, mandrel;2-1, positioning disk;2-2, screw thread;2-3, bolt hole;3, bolt;4, it props up Support set;5, tensioner;5-1, longitudinal gap;5-2, Contact Tooth;6, fastening screw;7, tapered sleeve;8, tensioner nut;9, pressing ring;10, Be open pressure pad;11, clamp nut.
Specific embodiment
Referring to FIG. 1 to FIG. 5, the utility model mainly by pedestal 1, mandrel 2, support sleeve 4, tensioner 5, tapered sleeve 7, pressing ring 9, Be open the compositions such as pressure pad 10.Wherein pedestal 1 is connected by T-slot with platen, and pedestal 1 and mandrel 2 pass through axis and hole It is connected with merging with four hexagon socket head cap screws 3;Support sleeve 4 and mandrel 2 form workpiece adjustable positioning mechanism, and the two is covered in mandrel On 2, and connected by tensioner nut 8 and mandrel 2;Tensioner 5 is matched with mandrel 2 by positioning spigot, and is fastened with fluting Screw 6 is fixed;Pressing ring 9 is pressed on workpiece (double dot dash line is workpiece to be processed in Fig. 1);Opening pressure pad 10 is pressed on pressing ring 9; Clamp nut 11 is connected through a screw thread with mandrel.When tensioner nut 8 is adjusted downwards, tapered sleeve 7 is driven to move down, tapered sleeve 7 supports 5 deformable segment of tensioner deforms outward, realizes that location dimension is adjusted.
The application method of the utility model: first according to the requirement in technical papers to fixture location dimension, pass through adjusting The location dimension (i.e. the external dimensions of tensioner 5) of positioning mechanism is adjusted to required value by tensioner nut 8, realizes the accurate of workpiece Positioning;Then workpiece blank to be processed is placed on 4 top of support sleeve, and passes through pressing ring 9, opening pressure pad 10 and clamp nut 11 Clamp workpiece;After the processing is completed, unclamping clamp nut 11 can be realized the disassembly of workpiece.When other workpiece to be processed repeat with Upper step only needs to change corresponding tensioner when location dimension difference is too big.
The utility model positions workpiece by the inner hole on workpiece, has and designs small and exquisite, easy to operate, positioning accurate The advantages that degree is high, speed is fast, has well solved gear teeth centering problem.The utility model greatly improves disc type gear Processing efficiency, it is ensured that processing quality and machining accuracy, meet product batch metaplasia production requirement.
