Description
Technical field
The utility model relates to a kind of machine tool component, particularly a kind of disengagement type safety handwheel.
Background technology
Handle and handwheel on the machine operation handwheel rotate along with the rotation of hand wheel shaft, are easy to scrape the operator, cause personal injury.At present, the method for general using folding handle solves, but handwheel still rotates, and is still dangerous.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the and then danger of rotation of handwheel in the safe handwheel, a kind of disengagement type safety handwheel is provided, when hand wheel shaft rotate, the handwheel wheel shaft that slips out of the hand fully made handwheel not follow hand wheel shaft to rotate together.
The technical solution of the utility model is: hand wheel shaft is supported on the casing, hand wheel shaft is provided with handwheel, it is characterized in that: hand wheel shaft is provided with trundle, be lined with drive sleeve between hand wheel shaft and the handwheel, one end of drive sleeve is provided with the driving groove that can be meshed with trundle, be connected with end cap on the other end of drive sleeve, be connected into the handwheel assembly between end cap, drive sleeve and the handwheel three; Be provided with stepped hole in the one end axle of transmission shaft, be provided with pivot pin in its stepped hole, be with spring on the pivot pin.
One end of pivot pin stretches out outside the end cap, and the axle head of its pivot pin is provided with stop nut.
Link by screw thread between end cap and the drive sleeve, interfixing by the unpacking screw between drive sleeve and the handwheel connects.
Pivot pin is fixed on the hand wheel shaft by trundle.
Trundle is provided with the locating sleeve that it is carried out axial location outward.
Can be provided with the driving groove more than two on the drive sleeve.
The utility model has the advantages that: handwheel assembly and hand wheel shaft are the disengaging type transmission, when handwheel is not worked, can break away from hand wheel shaft fully, make handwheel and not transfer of hand wheel shaft, have improved the security performance of lathe, and simple in structure, low cost of manufacture.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Number in the figure: 1-index dial, 2-casing, 3-trundle, 4-key, 5-hand wheel shaft, 6-back-up ring, 7-locating sleeve, 8-drive sleeve, 9-unpacking screw, 10-end cap, 11-stop nut, 12-adjust screw, 13-pivot pin, 14-spring, 15-handwheel, 16-driving groove.
Embodiment
Providing the utility model embodiment below in conjunction with accompanying drawing also describes in further detail:
Present embodiment is the disengagement type safety handwheel of a kind of use on the lathe slip crate,
Mainly be made up of hand wheel shaft 5, handwheel assembly, trundle 3, pivot pin 13, spring 14 and stop nut 11, hand wheel shaft 5 is supported on the casing 2, and the outside of casing 2 is provided with index dial 1, and index dial 1 is fixed on the hand wheel shaft 5 by key 4 and back-up ring 6.Hand wheel shaft 5 is provided with trundle 3, handwheel assembly, pivot pin 13 and spring 14, and pivot pin 13 is located in the axial step hole of hand wheel shaft 5, and spring 14 is placed on the pivot pin 13.The end of pivot pin 13 also is provided with stop nut 11 and adjusts nut 12.Trundle 3 radially inserts on the hand wheel shaft 5, and pivot pin 13 and hand wheel shaft 5 are cascaded, and carries out axial restraint.
The handwheel assembly is made of end cap 10, drive sleeve 8 and handwheel 15.Link by screw thread between end cap 10 and the drive sleeve 8, interfixing by unpacking screw 9 between drive sleeve 8 and the handwheel 15 connects, and the handwheel assembly is fixedly connected is one.The elastic force of its spring 14 directly acts on the handwheel assembly by end cap 10.
The handwheel assembly is placed on the hand wheel shaft 5, and can endwisely slip on hand wheel shaft 5.Drive sleeve 8 is lining between hand wheel shaft 5 and the handwheel 15, and an end of drive sleeve 8 is provided with the driving groove 16 that can be meshed with trundle 3, makes and realizes the disengaging type transmission between handwheel assembly and the trundle 3.Under the normal condition, the handwheel assembly is in disengaged condition with trundle 3 under the effect of spring 14, and at this moment, hand wheel shaft 5 rotates, and handwheel 15 does not and then rotate together; When needs rotate hand wheel shaft 5 rotations by handwheel 15, promote handwheel 15, overcome the pressure of spring 14, the end face driving groove 16 of drive sleeve 8 is meshed with trundle 3, rotate handwheel 15 then, rotate, carry out the hand feed campaign of lathe thereby drive hand wheel shaft 5; When hand feed finished, under the pressure of spring 14, handwheel 15 can be got back to normal disengaged condition, thus protection operating personnel's safety.
One end of pivot pin 13 stretches out outside the end cap 10, and the axle head of its pivot pin 13 is provided with stop nut 11, when the handwheel assembly is pulled out disengagement trundle 3, plays the effect of axial limiting.Also be provided with in the stop nut 11 and adjust screw 12.
For preventing trundle 3 axial floats, the outside of its trundle 3 is provided with the locating sleeve 7 that it is carried out axial location.
Can be provided with a driving groove on the drive sleeve 8, also can be provided with the driving groove more than two.If driving groove reaches some, the end of its drive sleeve 8 promptly becomes the end face engaging tooth that can mesh with trundle 3.
