Description
Technical field
The utility model belongs to the grinding attachment technical field, relates to a kind of fixture, particularly a kind of fixture for bore processing.
Background technology
The processing technology of mill is generally taked in the processing of the endoporus of gear, and due to gear, after Overheating Treatment, some all can occur for tooth-formation of gear and teeth directional changes, and in order to recover the precision of gear, the position of generally taking to do the reference circle of fixture clip tooth wheel is processed.The batch machining endoporus is lower by the method production efficiency of mill, and localization method is more loaded down with trivial details, and the fixture manufacturing cost is also higher, and fixture easily weares and teares and is not easy to management.Therefore, people improve this class fixture.
As Chinese utility model patent (application number: 201120441541.X, Granted publication number: CN 202292313 U) a kind of gear circular hole grinding fixture is disclosed, by rivet, pad, soket head cap screw, formed, it is characterized in that pitch cylinder is enclosed within the Ringent elastic cannula ring seat, with rivet, fix, to be no less than the quantity of three, uniform riveting is on collar inner face.This fixture adopts pitch circle centering form, utilize the contraction elasticity of Ringent elastic cannula ring seat, by pitch cylinder, gear centering is fixed in elastic collar, the magnetic force of recycling internal grinder for bearing race main shaft, be adsorbed on elastic collar and gear on main shaft and carry out grinding out processing.Due to elastic collar to inside contract power less, gear shifting quadrant texturing is less, therefore, after unloading, endoporus changes little, thereby has guaranteed the requirement of installing and using of interior hole dimension and cylindricity.
But, in this fixture, its process is: be pressed into part, tighten screw, determine that part puts in place and with the collar, pitch cylinder close contact non-loosening after, the processing of can installing.After processing, unclamp screw and take off part, complete part operation process.Because this fixture adopts the preliminary retaining element of screw position, its process is comparatively complicated.In addition, the clamping of its part is that the mechanically deform by the Ringent elastic cannula ring seat realizes, the long-time use, and the phenomenon of the easy fracture of Ringent elastic cannula ring seat, its course of work is unstable.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the fixture for bore processing that a kind of structure is comparatively simple and work is comparatively stable.
The purpose of this utility model can realize by following technical proposal: a kind of fixture for bore processing, comprise the retainer that is flat bulk, on one side of described retainer, circumferential ring is provided with several locating dowels for the locating element position, it is characterized in that, the same side of described retainer is provided with several clamps, described locating dowel can be to the inside under the extruding of clamp against, also be provided with the location structure that can make clamp and retainer locate mutually on described retainer, described clamp retainer relatively slides, described clamp and locating dowel axial location.
One end of locating dowel is fixed on retainer with iron wire, and therefore, locating dowel can swing to the inside under the extruding of clamp.Add man-hour, gear is put into to this fixture, locating dowel is fastened between adjacent two gear teeth of gear.Now, the locating dowel that circumferential ring is located on retainer can be by the gear Primary Location.The fixture that to put into again after gear is placed on the chuck of lathe, and the action of the claw of chuck, act on clamp.Due to the setting of location structure, clamp can only slide with respect to retainer.Clamp, toward medial movement, pushes locating dowel, and locating dowel is resisted against on gear to the inside, and gear is located.Afterwards, start gear is ground to processing or turning processing.
At the above-mentioned fixture for bore processing, described location structure comprises and is arranged on clamp away from cover plate and screw on a side of retainer, described cover plate in the form of a ring, there is the strip through hole on described clamp, described screw through the strip through hole and be connected in cover plate and retainer on.The effect that strip through hole and screw are set is that clamp is moved along the radial position of the formed circle of locating dowel.The set-up mode of screw is that through retainer, clamp and cover plate, the head of screw is positioned on retainer successively.The another kind of mode of screw setting is that through cover plate, clamp and retainer, the head of screw is positioned on cover plate successively.Cover plate is located by screw mutually with retainer, and clamp slides between cover plate and retainer.
At the above-mentioned fixture for bore processing, described location structure comprises screw, has the strip through hole on described clamp, and described screw passes the strip through hole and is connected on retainer.The head of screw is greater than the width of strip through hole, and the end away from head on screw is helicitic texture.Screw is connected on retainer, so has certain space between screw head and retainer, for clamp, slides.
The fixture for bore processing above-mentioned, be provided with hollow sleeve in described strip through hole, and described screw is through hollow sleeve.Sheathed hollow sleeve on screw, make the clamp can only be along the radially sliding of the formed circle of locating dowel, and can not swing to other direction, make the work of this fixture comparatively stable.
The fixture for bore processing above-mentioned, have outstanding limiting section on the side of described clamp away from retainer, and described limiting section is positioned at the inboard of cover plate.Limiting section is the surface away from retainer one side higher than clamp, for limiting the initial position of clamp.
At the above-mentioned fixture for bore processing, the middle part of described retainer is provided with manhole, the formed circular coaxial setting of described manhole and locating dowel.Gear is placed on this fixture and carries out turning, and the endoporus of machining gears, arrange manhole, moves for cutter, avoids the cutter fixture of damaging.
At the above-mentioned fixture for bore processing, described retainer has the limited step of the protrusion that limits clamp displacement near a side of clamp.Limited step, for limiting the position after clamp clamps, prevents that clamp from clamping excessive to gear.
At the above-mentioned fixture for bore processing, the quantity of described clamp is three and evenly is arranged on retainer, and is circumference.Corresponding to the quantity of clamp, for the chuck that clamps clamp, be scroll chuck.
At the above-mentioned fixture for bore processing, described locating dowel is provided with spigot surface away from an end of retainer.Spigot surface is tapered, is more convenient for gear is put into to this fixture.
Compared with prior art, this fixture for bore processing has the following advantages:
1, the clamping of gear has been adopted the mode of clamp, the course of work is comparatively stable.
2, limited step is set on retainer, prevents that clamp from clamping excessive.
The accompanying drawing explanation
