Description
Technical field
The utility model relates to a kind of machine cut clamp for machining, and specifically, the utility model relates to a kind of fixture for gear shaping, particularly a kind of for ring gear external tooth slotting fixture.
Background technology
Automobile synchronizer tooth ring is a kind of typical thin-walled driving member, the rigidity of this kind of thin-walled driving member is relatively weak, indeformable unavoidably in forming process, the most yielding stage occurs in the Gear Shaping stage, and deflection and ring gear are located in fixture, clamping structure is relevant with slotting impulsive force size.In order to reduce machining distortion, improve workmanship, the industry generally uses swollen dabber clamp to do the processing of ring gear positioning shaper.Swollen dabber clamp is the fixture of a kind of location and clamping integral structure, and its structure is relatively simple, and clamping is easy, and location is reliable, can accomplish accessible Gear Shaping.But the location of swollen dabber clamp mainly relies on built-in expansion set elastic deformation to realize, and the positioning precision of this kind of floating location structure, affects by factors such as the open slot uniformity on expansion set wall, expansion set material and thermal treatment qualities.The positioning precision of swollen dabber clamp can not be very high thus, is difficult to reach the supporting requirement of high-grade car with the ring gear that swollen dabber clamp is processed.
Utility model content
The utility model is mainly for the deficiency of prior art products, a kind of ring gear external tooth slotting fixture adopting radial location, axial grip structure is proposed, this clamp structure is simple, registration, reliable lock, reasonable stress, and ring gear crudy is stable and precision is high.
The utility model is achieved through the following technical solutions technical goal.
Ring gear external tooth slotting fixture, it forms reason jointly by pull bar, pad, axle bed, axle sleeve and pedestal.Described pedestal is that a joint erects the hollow shaft section of putting, and end face is upward provided with recessed seam location and installation axle bed.Described pull bar is the rod member that up-downgoing passes, and pull bar runs through pedestal endoporus, and the annular groove that the rod end outer wall of upper dew is provided with is equipped with pad composition linkage structure.Its improvements are: described axle bed is Multi-section shaft component, and be in two upper and lower nodal axisn sections of evagination shoulder coaxial, a upper nodal axisn section external diameter and inner hole of workpiece matched in clearance form radial positioning structure.Directly and axle bed fit, axle sleeve is between pedestal and workpiece opposing end surface, and workpiece is by with the descending pad axial locking of pull bar for described axle sleeve.
The outside diameter of said structure bottom bracket axle and pad is less than the root diameter 2 ~ 6mm of workpiece external tooth.Axle sleeve axially mounting workpiece, makes workpiece bottom face and axle bed axially alternate 1 ~ 3mm.In order to reach the object of quick dispatch, pad is open washer structure.
The utility model compared with prior art, has following good effect:
1, workpiece is linked on axle bed outer wall, and this kind of location structure is simple, and accurate positioning, the most important thing is that thin-wall workpiece does not have radial load effect when gear shaping, therefore be out of shape minimum;
2, axle sleeve axially mounting workpiece, make workpiece bottom face axially alternate with axle bed, the workpiece increment face of suspension is compressed by the pad dynamic with pull bar, and this kind of axial locking structure accomplishes that workpiece thin-walled does not bear axial force, therefore axial locking structure is reasonable.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Ring gear external tooth slotting fixture shown in Fig. 1, it is made up of pull bar 1, pad 2, axle bed 3, axle sleeve 4 and pedestal 5, and this fixture location and installation is on gear shaper workbench.Described pedestal 5 is main components of fixture, for carrying other supporting component.The perpendicular pedestal 5 put is joint hollow shaft section, and end face is upward provided with recessed seam, and this seam is used for location and installation axle bed 3.Axle bed 3 is Multi-section shaft component, is in two upper and lower nodal axisn sections of evagination shoulder coaxial, is positioned at a beneath nodal axisn section and coordinates with pedestal 5 recessed seam upward, the axle bed of location is rotated with pedestal 5.The shaft part being positioned at a joint is located for workpiece 6, its external diameter and workpiece 6 endoporus matched in clearance, the radial positioning structure of this structure composition workpiece 6.Although radial positioning structure is simple, accurate positioning and reliable, largest benefit is that thin-walled is not by radial load effect when gear shaping for workpiece 6, so workpiece 6 form trait after processing obtains very well, and steady quality, product manufacturing precision meets the supporting requirement of high-grade car.Described axle sleeve 4 directly with axle bed 3 fit, axle sleeve 4 is between pedestal 5 and workpiece 6 opposing end surface, and axle sleeve 4 axially mounting makes workpiece 6 suspend, and its bottom face is alternate with axle bed 3 axis, alternate 1.5mm in the present embodiment.Described pull bar 1 is the rod member of up-downgoing, and pull bar 1 runs through pedestal 5 endoporus, and upper end outer wall is provided with annular groove, and annular groove coordinates with pad 2 and forms linkage structure, and upper behavior is unclamped, lower behavior axial locking.Described pad 2 is a kind of open washers, and can insert from pull bar 1 side or extract, such being combined be beneficial to workpiece 6 quick dispatch.In order to not affect Gear Shaping, the outside diameter of axle sleeve 4 and pad 2 is smaller than the root circle of workpiece 6 external tooth, the little 2mm of the present embodiment bottom bracket axle 4, the little 6mm of pad 2.
During the actual use of the utility model, first temporary removal pad 2, overlaps workpiece 6 and installs on axle bed 3 outer wall and by axle sleeve 4 axially mounting, reinsert pad 2 from pull bar 1 annular groove side, then affect pull bar 1 with power, descending pull bar 1 links packing ring 2 axial locking workpiece 6.External tooth shaping can be implemented after workpiece 6 obtains radial location and axial locking.Just can unload workpiece 6 once complete gear shaping operation, concrete operations are, introduce power and are risen by pull bar 1, remove the axial locking to workpiece 1, then take out pad 2, direct-axis seat 3 unloads the workpiece 6 completed, again the workpiece 6 changing the outfit to be processed, repeats above-mentioned installation process and implements reprocessing.The utility model is not enough for thin-walled ring gear rigidity, the problem that Gear Shaping easily causes thin-walled to be out of shape, adopt radial location and axial locking structure, make the thin-walled of workpiece 6 in fixture neither by radial load effect, also not by responsive to axial force, thus reach reduction machining distortion, improve the object of machining accuracy.
