The support is L-shaped, and a slideway is arranged on one - leg of the support, while the rotating shaft seat is arranged on the other right-angle side of the support. The upper compact heap is arranged on the slideway of the support; the indexing rotating shaft is arranged on the rotating shaft seat, wherein the chuck is arranged on the upper end of the indexing rotating shaft, and the lower end of the indexing rotating shaft is connected with the electromagnetic brake; a crankshaft is clamped on the chuck and is compressed by using the upper compact heap; the indexing rotating shaft is driven by a synchronous belt wheel and a synchronous belt through the indexing motor; under the driving of the indexing motor, the chuck is driven to rotate by a predetermined angle and is locked by the electromagnetic brake. The crankshaft automatic indexing holddown device provided by the present invention has the advantages of compact structure, reliable positioning, efficient compacting motion and low labor intensity so that the crankshaft automatic indexing holddown device is especially suitable for the indexing compaction when drilling crankshaft flange holes.
Description
Technical field
The present invention relates to a kind of calibration hold down gag, specifically a kind of bent axle automatic indexing hold down gag that in the Production of Crankshaft process, bores bent axle deep bid flange hole with radial drill.
Background technology
We know, are uniform-distribution with one group of circular hole on the deep bid end face of flange of bent axle.When drilling should be organized circular hole on radial drill, need to use bushing plate carry out calibration.Promptly move the gear-box of radial drill, make the pilot hole on the drill bit bushing plate, carry out drilling then.This calibration mode, not only indexing accuracy is low, and is difficult in the automation that realizes boring on the radial drill.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, and a kind of compact conformation is provided, and calibration, location reliably compress the efficiency of movement height, the bent axle automatic indexing hold down gag of the brill bent axle deep bid flange hole that operator's working strength is low.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of bent axle automatic indexing hold down gag, and it comprises support, goes up compact heap, chuck, electromagnetic brake, calibration rotating shaft, shaft seat, indexing motor, and it is characterized in that: said support is L-shaped; The one of which right-angle side is provided with slideway, on another right-angle side shaft seat is installed, and last compact heap is installed on the slideway of support; Can slide up and down, the calibration rotating shaft is installed in the shaft seat, and its upper end is equipped with chuck; The lower end is connected with electromagnetic brake, and bent axle is clamped on the chuck, and uses compact heap and compress; The calibration rotating shaft by indexing motor through small synchronous pulley, synchronously with and the big synchronous pulley that is installed in the calibration rotating shaft drive; Under indexing motor ground drives, drive chuck and rotate predetermined angle, and lock by electromagnetic brake.
The back side of the said slideway of the present invention is provided with the flat board of a support leading screw; Last compact heap one end is top to having; The other end has and outwards is provided with outstanding screw plate, and the breach that screw plate passes support is connected cooperation with leading screw, and rotational lead screw can drive compact heap and slide up and down.After last compact heap compresses bent axle, it is locked through clamping screw.
The said indexing motor of the present invention is stepper motor or servomotor.
When the present invention works, the workpiece bent axle is clamped on the chuck, and uses compact heap and compress.Chuck drives the angle that turns over regulation down together with workpiece on indexing motor ground, make the position alignment drill bit of desire boring on the bent axle deep bid flange, accomplishes calibration and moves.Then by electromagnetic brake with calibration rotating shaft and chuck braking and locking, drill bit carries out bore operation.
The present invention adopts said structure, against existing technologies, and its compact conformation; Calibration, location reliably compress the efficiency of movement height, have shortened the non-cutting time of process; Reduced operator's labour intensity, be particularly suitable for boring bent axle deep bid flange hole calibration and compress use.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further description.
Fig. 1 is a structural representation of the present invention.
Label among the figure is: go up compact heap, 2. leading screw, 3. clamping screw, 4. support, 5. chuck 1.; 6. shaft seat, 7. calibration rotating shaft, 8. electromagnetic brake, 9. big synchronous pulley is 10. near switch; 11. round nut, 12. flat keys, 13. circlips for shaft, 14. signal panels, 15. are with synchronously; 16. small synchronous pulley, 17. bolts, 18. motor mounts, 19. indexing motors, 20. bent axles.
The specific embodiment
As can be seen from Figure 1, a kind of bent axle automatic indexing hold down gag, it comprises compact heap 1, leading screw 2, clamping screw 3, support 4, chuck 5, shaft seat 6, calibration rotating shaft 7, electromagnetic brake 8, indexing motor 19 etc.
Said support 4 is " L " square, and an one of which right-angle side is provided with slideway, and shaft seat 6 installing holes and indexing motor 19 installing holes are arranged on another right-angle side.Last compact heap 1 is installed on the slideway of support 4, can slide up and down.Calibration rotating shaft 7 is installed in the shaft seat 6, and indexing motor 19 is installed on the motor mount 18 that is fixed on the support 4 through bolt 17.Specifically be to have a flat board to be used to support leading screw 2 at the back side of slideway; Last compact heap 1 one ends are top to having; The other end has and outwards is provided with outstanding screw plate, and the breach that screw plate passes support 4 is connected cooperation with leading screw, and rotational lead screw 2 can drive compact heap 1 and slide up and down.After last compact heap 1 compresses bent axle 20, it is locked through clamping screw 3.
Said shaft seat 6 is fixed on the shaft seat installing hole of support 4, and calibration rotating shaft 7 is installed in the shaft seat 6, and its upper end is equipped with the chuck 5 that is used to tighten bent axle 20, and the lower end is connected with electromagnetic brake 8, and with round nut 11 lockings.Bent axle 20 is clamped on the chuck 5, and uses compact heap 1 and compress.Calibration rotating shaft 7 by indexing motor 19 through small synchronous pulley 16, synchronously with 15 and the big synchronous pulley 9 that is installed in the calibration rotating shaft 7 drive.Big synchronous pulley 9 is installed in calibration rotating shaft 7 lower ends through flat key 12.
Under indexing motor 19 drove, after turning over the angle of regulation, indexing motor 19 stopped operating, electromagnetic brake 8 energising braking calibration rotating shafts 7.And lock by electromagnetic brake.Below calibration rotating shaft 7, also signal panels 14 are installed and, are used to control the feed motion of radial drill main shaft near switch 10 through circlip for shaft 13.
The said indexing motor 19 of the present invention is stepper motor or servomotor.
When the present invention works, the workpiece bent axle is clamped on the chuck, and uses compact heap and compress.Chuck drives the angle that turns over regulation down together with workpiece on indexing motor ground, make the position alignment drill bit of desire boring on the bent axle deep bid flange, accomplishes calibration and moves.Then by electromagnetic brake with calibration rotating shaft and chuck braking and locking, drill bit carries out bore operation.Its compact conformation, calibration, location reliably compress the efficiency of movement height, have shortened the non-cutting time of process, have reduced operator's labour intensity, are particularly suitable for boring bent axle deep bid flange hole calibration and compress use.
