Abstract
The invention discloses a positioning self-centering main shaft chuck capable of overturning plus or minus 180 degrees. The main shaft chuck comprises a swingable clamping expansion chuck (1), a main shaft rotating mechanism (2), a turnover mechanism (3) and a three-loop swivel joint (1). The positioning self-centering main shaft chuck is characterized in that a hydraulic motor (2-8) drives a driven bull gear (2-3) and the main shaft rotating mechanism to rotate; a blank wheel hub is horizontally clamped through self-centering linked three claws to determine a machining center,; after a dead head is cut through the main shaft chuck in positive rotation, the main shaft chuck stops rotating; a hydraulic anti-gravity valve locks a clamp; after reverse slow 180-degree positioning is performed to the chuck, lateral waste material is machined; and after a sensing block (7) is sensed through a photoelectric switch (6), the chuck is immediately stopped, and the machining is finished. The positioning self-centering main shaft chuck has the advantages that the clamp is not required to be centered and positioned manually, centre positioning and overturning are completely automatic, and plus or minus 180 degrees position are automatically determined during machining. The chuck can be conveniently matched with a magic hand to realize automatic work piece loading and unloading, so that unmanned machining can be implemented.
Description
Technical field
The invention belongs to machining special purpose machine tool technical field, be applied to the heavy castings machining tool, the particularly blank of vehicle hub low pressure or high-pressure casting part processing.
Background technology
The advantages such as aluminum-alloy wheel is lightweight, energy-conservation with it, good heat dissipation, attractive in appearance, corrosion-resistant, processability is good are constantly approved, adopt aluminum-alloy wheel to become the optimal selection that substitutes the steel wheel, so that the sharp increase of aluminium alloy vehicle rim demand.The high speed of automobile forces aluminum-alloy wheel to major diameter, wide wheel rim future development, and at present 14-16in of main flow is progressively replaced by 17-20in, even the 21-28in wheel occurs and be contained on the automobile.So the applicant's application in once 2011 patent of invention: a kind of turnover spindle chuck, application number are: 201210076829.0, to swing expansion chuck the rectilinear motion of spindle chuck is converted into rotatablely moves, to rotatablely move again and be converted into rectilinear motion, can realize many clamping jaw linkeds, make the drive of spindle rotation mechanism and switching mechanism can swing expansion chuck and do the 0-90o upset.The 0-90o upset can only be done but the defective of this structure is spindle rotation mechanism and switching mechanism, and the 0-180o upset can not be realized.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of turning ± 180 ° location self-centering spindle chuck, these anchor clamps are put into the blank wheel hub when horizontal, by self-centering interlock three-jaw wheel hub is clamped simultaneously definite center, then plough under machine tooling, add the quick forward machine tooling of anchor clamps in man-hour center riser, after the completion of processing center riser, anchor clamps carry out processing the side waste material behind 180 ° of location of slow reverse.
Technical scheme of the present invention is achieved in the following ways: a kind of turning ± 180 ° location self-centering spindle chuck, comprise and to swing expansion chuck, spindle rotation mechanism, switching mechanism and three loop swivel couplings, can swing expansion chuck is located on the spindle chuck, two sides of spindle chuck are connected with spindle rotation mechanism and switching mechanism, spindle rotation mechanism and switching mechanism drive can swing expansion chuck and do the 0-90o upset, and described spindle rotation mechanism comprises swing clamping device seat board, passive gear wheel, driving pinion and CD-ROM drive motor; The below of spindle chuck is provided with supporting seat, has a groove at supporting seat, and 180o location inductive switch and sensor block are installed in the groove, it is characterized in that: described hydraulic motor drives passive gear wheel and spindle rotation mechanism rotation; The blank horizontal hub is clamped by self-centering interlock three-jaw determines machining center, behind the forward excision rising head, spindle chuck stops the rotation, the dead anchor clamps of the anti-lotus block of valve of hydraulic pressure, the beginning of chuck location is oppositely processed the side waste material behind 180 ° of location at a slow speed, chuck stops completion of processing at once after sensing sensor block by optoelectronic switch.
Structure of the present invention, anchor clamps need not artificial centering and location, and ± 180 ° position is determined in completely self-centering position and upset automatically in the processing.Reduce difficulty and the labour intensity of employee's workpiece loading and unloading, improved working (machining) efficiency, quality and the yield rate of product.Because anchor clamps have Self-centering Action, can cooperate realization automated handling workpiece very easily with between the manipulator, realize unmanned processing.

Among the figure: 1 can swing expansion chuck, 2 spindle rotation mechanisms, 3 switching mechanisms, 4 three loop swivel couplings, 5 supporting seats, 6 are 180o location inductive switch, 7 sensor blocks, 2-1 swings the clamping device seat board, 2-2 main shaft axle core, the passive gear wheel of 2-3, the 2-4 driving pinion, the 2-5 main shaft bearing, the 2-6 main shaft sleeve, 2-7 three road swivel couplings, the 2-8 CD-ROM drive motor, 3-1 main shaft seat board, 3-2 oil cylinder rod end supporting seat, 3-3 turning-over support seat, the 3-5 base, the 3-6 upset drives oil cylinder, 3-7 oil cylinder supporting seat, the 3-8 Level tune supports.
The specific embodiment
Known by Fig. 1, the spindle chuck of a kind of turnover 180o location, comprise swinging expansion chuck 1, spindle rotation mechanism 2, switching mechanism 3 and three loop swivel couplings 4, can swing expansion chuck 1 and be located on the spindle chuck, two sides of spindle chuck are connected with spindle rotation mechanism 2 and switching mechanism 3.
Known the spindle rotation mechanism cutaway view by Fig. 2.Switching mechanism 3 comprises main shaft seat board 3-1, oil cylinder rod end supporting seat 3-2, turning-over support seat 3-3, base 3-5, upset drives oil cylinder 3-6, oil cylinder supporting seat 3-7, Level tune supports 3-8, main shaft seat board 3-1 is connected on the spindle chuck, the oil cylinder rod end supporting seat 3-2 that the bottom of main shaft seat board 3-1 is provided with, turning-over support seat 3-3 supports 3-8 with Level tune and links to each other with base 3-5, be fixed with upset among cylinder rod end supporting seat 3-2 and the oil cylinder supporting seat 3-7 and drive oil cylinder 3-6, vertical adjusting supports the side that 3-4 is located at main shaft seat board 3-1 and base 3-5, and the spindle chuck below is provided with supporting seat 5.
Known by Fig. 3, fluting is equipped with 180o location inductive switch 6 and sensor block 7 on the supporting seat 5, and spindle rotation mechanism 2 and switching mechanism 3 drives can swing expansion chuck 1 and do the 0-90o upset, drive passive gear wheel 2-3 and spindle rotation mechanism rotation by hydraulic motor 2-8; Chuck stops the rotation, and chuck is backward rotation after the beginning of location, and 180o location inductive switch 6 is sensed sensor block 7 rear chucks and stopped at once the dead chuck of the anti-lotus block of valve of hydraulic system.Chuck location beginning is oppositely processed the side waste material behind 180 ° of location at a slow speed, sense 7 sensor blocks by optoelectronic switch 6 after chuck stop at once completion of processing.
Being known by Fig. 4, is the wheel hub blank figure that low press is produced.Low pressure and high-pressure casting are that side from wheel hub enters aluminium hydraulic pressure at wheel hub blank in when casting.So just stay next cast gate slitter edge in the side of wheel hub blank, before, removing the side slitter edge all is to have wheel hub blank by personnel in arms with hand, on common edge polisher slitter edge is ground off.This method, working (machining) efficiency is low, and the side quality of processing is unstable, and operating personnel are to add the man-hour potential safety hazard larger.Adopt structure of the present invention, can disposable inner edge and side excision with wheel hub blank.
