Description
Technical field
The utility model relates to double-ended grinding machine feeding field, and specifically the special feeding of a kind of vertical paralleled surface grinding machine gets stuck slipping device.
Background technology
At present, vertical disc formula double-ended grinding machine is all adopt feed mechanism to drive feeding disc rotary, in the side of feeding disk, upper and lower emery wheel is installed, the hole that feeding disk pre-sets put into by workpiece, then follow feeding disk rotational, enter the grinding that upper and lower two end faces of workpiece are carried out in grinding area.Feeding disk is caused to stop operating owing to there will be a lot of problem in actual process, the unexpected wide-angle tilt of such as workpiece blocks feeding disk, upper and lower emery wheel feeding is excessive causes feeding disk asphyxia by external pressure on the chest and abdomen etc., so must ensure when feeding disk stops operating suddenly, feeding structure also must stop simultaneously, or feeding structure is rotated further, but there is relative sliding between feeding disk and feeding structure, otherwise generation is damaged by feeding motor and feeding structure related components.
Summary of the invention
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, simple to operate, and can not cause the slipping device that gets stuck of damage when can ensure that feeding disk gets stuck to lathe.
The utility model taked technical scheme that solves the problem is: the special feeding of a kind of vertical paralleled surface grinding machine gets stuck slipping device, be provided with feeding disk, bakelite pad, top cover, spring, front nut, back nut, screw mandrel, silk seat, round nut, base, driving shaft, key, upper emery wheel, lower grinding wheel, it is characterized in that: described feeding disk is in laterally placing, base is provided with in the bottom of feeding disk, described driving shaft is in the center of base, key is provided with between driving shaft and base, driving shaft drives base rotation by key, a round nut is provided with outside the top of driving shaft, round nut is for ensureing the invariant position of base on driving shaft, a bakelite pad is provided with on feeding disk top, bakelite pad top is provided with top cover, top cover lower end is fixed on chassis interior by keyway, and can slide up and down at chassis interior, in the central upper groove of top cover, be provided with spring, spring top is provided with front nut, front nut top is provided with back nut, be provided with a screw mandrel vertically placed at the center of spring, front nut, back nut, screw mandrel lower end is provided with silk seat, and silk seat is fixed on driving shaft, emery wheel on being provided with on the right side of feeding disk, is provided with lower grinding wheel below right side, and workpiece is placed in the hole that feeding disk is preset, and along with feeding disk rotational enters the space between upper emery wheel and lower grinding wheel, completes the grinding of upper and lower two end faces of workpiece.
The utility model is owing to taking said structure, and the slip structure that feeding got stuck eliminates the potential safety hazard that gets stuck, ensure that the security of feeding structure, ensure that the service life of lathe after introducing the pay-off of vertical paralleled surface grinding machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is feeding disk of the present utility model and emery wheel position top view.
Be labeled as in figure: 1. feeding disk, 2. bakelite pad, 3. top cover, 4. spring, nut 5., 6. back nut, 7. screw mandrel, 8. a seat, 9. round nut, 10. base, 11. driving shafts, 12. keys, emery wheel on 13., 14. lower grinding wheels.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As Fig. 1, shown in Fig. 2, the utility model relates to the special feeding of a kind of vertical paralleled surface grinding machine and to get stuck slipping device, be provided with feeding disk 1, bakelite pad 2, top cover 3, spring 4, front nut 5, back nut 6, screw mandrel 7, silk seat 8, round nut 9, base 10, driving shaft 11, key 12, upper emery wheel 13, lower grinding wheel 14, it is characterized in that: described feeding disk 1 is in laterally placing, base 10 is provided with in the bottom of feeding disk 1, described driving shaft 11 is in the center of base 10, key 12 is provided with between driving shaft 11 and base 10, driving shaft 11 drives base 10 to rotate by key 12, a round nut 9 is provided with outside the top of driving shaft 11, round nut 9 is for ensureing the invariant position of base 10 on driving shaft 11, a bakelite pad 2 is provided with on feeding disk 1 top, bakelite pad 2 top is provided with top cover 3, it is inner that top cover 3 lower end is fixed on base 10 by keyway, and can slide up and down in base 10 inside, in the central upper groove of top cover 3, be provided with spring 4, spring 4 top is provided with front nut 5, front nut 5 top is provided with back nut 6, be provided with a screw mandrel 7 vertically placed at the center of spring 4, front nut 5, back nut 6, screw mandrel 7 lower end is provided with silk seat 8, and silk seat 8 is fixed on driving shaft 11, emery wheel 13 on being provided with on the right side of feeding disk 1, lower grinding wheel 14 is provided with below right side, workpiece is placed in the hole that feeding disk 1 is preset, and along with feeding disk 1 rotates the space entered between upper emery wheel 13 and lower grinding wheel 14, completes the grinding of upper and lower two end faces of workpiece.
The utility model in use, feeding disk 1 is arranged on base 10, successively bakelite pad 2, top cover 3, spring 4, front nut 5, back nut 6 are arranged on leading screw 7, nut 5 before downward adjustment, making the elastic force of spring 4 can extrude top cover 3 drives bakelite pad 2 and feeding disk 1 to rotate, then regulate back nut 6, make back nut 6 can ensure can not move, to ensure the elasticity stable of spring 4 in the process that front nut 5 rotates at feeding structure.When getting stuck appears suddenly in lathe in process, feeding disk 1 cannot rotate because fault is stuck, and driving shaft 11 is rotated further under the drive of feeding motor, driving shaft 11 drives base 10 and top cover 3 to be rotated further, spring 4 forced compression, top cover 3 upwards does small distance and slides, the thrust of top cover 3 pairs of feeding disks 1 weakens, finally make to produce relative sliding between bakelite pad 2 and feeding disk 1, effectively reduce the load of parts in feeding motor and feeding structure, guarantee that each parts can not cause the excessive generation of load to damage because getting stuck, bakelite pad 2 between feeding disk 1 and top cover 3 effectively can reduce the wearing and tearing of top cover 3 and feeding disk 1.
