Description
Technical field
The utility model belongs to speed changer machining tool fixture technical field, is specifically related to a discharge plate class smart car and quickly cuts
Change fixture.
Background technique
It is well known that the gear components inside speed changer are many kinds of, processing must be therefore right by frock clamp
Just need to match different frock clamps in different types of gear, the frock clamp that will lead to processing gear in this way is also numerous
More, frock making is at high cost；In addition, to process the switching that different types of gear just needs to carry out frock clamp, and tooling is pressed from both sides
The switching of tool generally requires 60~70min, will lead to that the gear manufacture period is long in this way, influences the capacity and output of gear.
The first working procedure of Gear Processing is to carry out smart car to disk class raw material, and smart car quality will will have a direct impact on finished gear
Processing quality, therefore its importance is self-evident.Traditional disk class lathe finish fixture is usually used outside for disk-like accessory smart car
The fixture of circle, end face and inner hole, and the smart car process of general disk class be use elder generation using black skin as one end face of positioning surface smart car, then
The mode of smart car other end is reversed end for end to complete the processing of entire workpiece configurations profile.When using black skin as positioning surface smart car one end
When face, the geometric tolerance of end face axial size and inner hole can be guaranteed by cutter and equipment, and when smart car other end, it is full
The processing of foot procedure and design requirement, the requirement on machining accuracy of the relatively previous end face of the machining accuracy of other end are higher；Also
Have, at smart car other end, if workpiece end face is not developed with tooling end face, it will cause position end face axial dimension with it is interior
Hole geometric tolerance is overproof, influences next procedure processing, and overproof serious person will directly scrap, and influences gear quality and qualification rate.
Utility model content
For the above-mentioned prior art, the technical problem to be solved by the present invention is to provide one kind can reduce frock making
Cost shortens the workpiece manufacturing cycle, guarantees that processing quality, the disk class smart car for improving production efficiency are switched fast fixture.
In order to solve the above technical problems, the utility model, which provides a discharge plate class smart car, is switched fast fixture, including installation
Oblique-pulling type chuck on lathe, the positioning base being fixedly mounted on oblique-pulling type chuck bottom surface and circumferential it is evenly arranged on cable-stayed type card
Three claws tried to get to the heart of a matter on face, the shape of the positioning base be set as inverted T shaped and its top be set as can covering be packed into it is described tiltedly
