Abstract
A kind of fluted disc slides pawl machining spiral groove device and technique, processing unit (plant) is mainly by main body, eccentric shaft, ejector pin, spring, positioning pin forms, the T-slot of four radial directions is provided on the front end face of main body, in T-slot pawl is slided for clamping workpiece fluted disc, there are four radial eccentric shafts for setting in the middle part of main body, the position of eccentric shaft is corresponding with T-slot, matched ejector pin is provided with before eccentric shaft, it is provided with positioning pin at eccentric shaft and main body cooperation, lead plug two axial the fabrication hole A and B on the back side that workpiece fluted disc slides pawl, when ejector pin is withstood on respectively in fabrication hole A and B, pawl helicla flute is slided to fluted disc by same feed parameter and carries out twice of turning.The present invention slides fluted disc the processing of pawl helicla flute, and a station two procedures can be completed, high in machining efficiency, and high precision machining.
Description
Technical field
The present invention relates to a kind of mechanical technique, specially a kind of fluted disc slides pawl machining spiral groove device.
Background technology
In intermetallic composite coating, woodenware processing, there are many having chuck on the main shaft of equipment, it is used for clamping workpiece.Chuck
Major part is fluted disc and fluted disc slides pawl, is machined with uniform pitch end face helical tooth on the end face of fluted disc, end face helical tooth is radially
Screw pitch be fixed value, the radius of curvature of whole helical tooth is variation, and closer to the fluted disc center of circle, radius of curvature is smaller, remoter
From the fluted disc center of circle, radius of curvature is bigger.Part with fluted disc cooperation is that fluted disc slides pawl, and fluted disc is slided and is machined with helicla flute, spiral shell on pawl
Spin slot coordinates with the helical tooth on fluted disc end face.In use, while fluted disc slides pawl and fluted disc relative rotation, fluted disc is slided
Pawl will also be moved radially along fluted disc, the workpiece of different-diameter is clamped.Since the helical tooth on fluted disc is uniform pitch, variable curvature half
Diameter, so, fluted disc slides the helicla flute on pawl, it is necessary to assure can at fluted disc center, the cooperation of helical tooth that radius of curvature is small,
Can and fluted disc periphery at, the big helical tooth cooperation of radius of curvature, and fluted disc end face helical tooth fit clearance is too small can influence to slide,
The final precision of chuck is influenced with the too conference of fluted disc end face helical tooth fit clearance, so, the helicla flute that fluted disc is slided on pawl has
Certain particularity, appearance and size and processing method are all at the principal element for influencing chuck processing.Fluted disc slides the spiral shell on pawl
Spin slot usually by CNC milling machine, takes single-piece reparation again after analogy method single-piece work or more than one piece turning, not only processing effect
Rate is low, and machining accuracy is poor.
Invention content
The purpose of the present invention is to provide a kind of processing unit (plant), clamped one time more than one piece fluted disc slides pawl, more than one piece fluted disc slide pawl at
Group processing, by same turning track, the machining spiral groove on fluted disc cunning pawl is completed in successively turning twice, not only high in machining efficiency,
And the fit clearance that fluted disc slides pawl and fluted disc can also be efficiently controlled.
To achieve the above object, present invention employs following technical schemes：
Fluted disc slides pawl machining spiral groove device, is mainly made of main body, eccentric shaft, ejector pin, spring, positioning pin, main body
It is provided with the T-slot of four radial directions on front end face, clamping workpiece fluted disc is used in T-slot and slides pawl, there are four the settings of main body middle part
Radial eccentric shaft, the position of eccentric shaft is corresponding with T-slot, is provided with matched ejector pin before eccentric shaft, outside ejector pin
Disc is equipped with spring, is provided with positioning pin at eccentric shaft and main body cooperation, two axis are arranged on the back side that workpiece fluted disc slides pawl
To fabrication hole A and B, the distance of two fabrication holes is equal to helicla flute（Tooth）The multiple of screw pitch, when ejector pin is withstood in fabrication hole B,
Fluted disc is slided at minimum grip diameter when pawl should be at work, and when ejector pin is withstood in fabrication hole A, fluted disc slides pawl and should be at work
When maximum grip diameter at.
When processing fluted disc cunning pawl helicla flute, the rear portion clamping of main body slides pawl in lathe chuck, by fluted disc and is inserted into T-slot
Interior, ejector pin is withstood in fabrication hole B, rotating eccentricity shaft locking ejector pin, and sliding pawl helicla flute design requirement by fluted disc is arranged lathe tool feed
Parameter, turning fluted disc slide pawl helicla flute, and then ejector pin is withstood on again in fabrication hole A, and pawl helicla flute is slided to fluted disc by former feed parameter
The 2nd time turning is carried out, processing is completed.
The present invention slides fluted disc the processing of pawl helicla flute, and a station two procedures can be completed, high in machining efficiency, and
High precision machining.
