Technical field
The utility model relates to a kind of calibration hold down gag, specifically a kind of bent axle automatic indexing hold down gag that bores bent axle deep bid flange hole in the Production of Crankshaft process 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 the gear-box of mobile radial drill makes the pilot hole on the drill bit bushing plate, carries 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 in the utility model is to overcome above-mentioned the deficiencies in the 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 in the invention for solving the above technical problem is: a kind of bent axle automatic indexing hold down gag, it comprises support, last compact heap, chuck, electromagnetic brake, the calibration rotating shaft, shaft seat, indexing motor, it is characterized in that: described support is L-shaped, the one right-angle side is provided with slideway, on another right-angle side shaft seat is installed, 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, 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 is passed through small synchronous pulley by indexing motor, 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 utility model 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 by clamping screw.
The said indexing motor of the utility model is stepper motor or servomotor.
In the utility model when work, be clamped in the workpiece bent axle on the chuck, and use compact heap and compress.Chuck turns over the angle of regulation together with workpiece under indexing motor ground drives, make the position alignment drill bit of desire boring on the bent axle deep bid flange, finishes the calibration action.Then by electromagnetic brake with calibration rotating shaft and chuck braking and locking, drill bit carries out bore operation.
The utility model 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
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Label among the figure is: go up compact heap, 2. leading screw, 3. clamping screw, 4. support 1., 5. chuck, 6. shaft seat, 7. calibration rotating shaft, 8. electromagnetic brake, 9. big synchronous pulley, 10. near switch, 11. round nuts, 12. flat key, 13. circlips for shaft, 14. signal panels, 15. be with 16. small synchronous pulleys, 17. bolts synchronously, 18. motor mount, 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.
Described support 4 is " L " square, and an one 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 by 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 by 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 locks with round nut 11.Bent axle 20 is clamped on the chuck 5, and uses compact heap 1 and compress.Calibration rotating shaft 7 by indexing motor 19 by 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 by flat key 12.
