Definitions
- the body has obviously, time-wasting especially in the later stages when the grinding operation nears completion.
- gauge being and to be moved, in order to test' or gauge the movement of away from into or towards the during a return
- the gauging can thus be performed without stopping the machine, and working spindle, going grinding,
- Fig. 1 is a longitudinal section of a working spindle of a grinding machine provided with a gage in accordance with the invention.
- Fig. 2 isan elevation partly in section ot a portion of a grinding machine embodying my invention, showing the means for moving the caliper gage cut-on or declutching and for operating a device, the grinding ESS OF WORK IN MACHINES FOR OF REVOLUTION.
- Fig. 3 is a similar view showing the grinding wheel free of the work and the caliper gage advanced in engaging relation with the same.
- a sleeve 3 rotating with the spindle but adapted to be moved axially relatively thereto, the connection for permitting time being for instance a pin 1 attachedto the spindle and located in a slot 5 in the sleeve 3 extending parallel to the axis of the sleeve.
- the sleeve 3 at one end carries a cali rgauge consisting, for instance, of :1 ed shoulder arm or abutment 6 and a diametrically opposed shoulder arm or abutment 7 seated in a radial slot in-the ring 8 and ad- 'justable in said slot edativcly to the part 6;
- the adjustment ofthe abutment '7' is .efiected by means of an adjusting. screw 7 threaded 1n the ring. 8, with the head of the screw in position to engage the outer edge of the abutment, which latter is held in its adjusted position by means of a binding screw 7" 8 carried by sleeve 3and engaging the side edge of the abutment.
- the caliper-gauge can be moved body 2 for the purpose of testingits diame ter when the reciprocating grinding disc has moved away from the body and calipercontacting portions of the gauge.
- the work uge are thus carried by the ring 8 and the fitter is permitted a certain amount of radial free threaded in the outer end of a ring the sleeve along the 1 or floating movement relatively to the sleeve 3.
- of the ring 8 is provided with a flange 9, engaging the front end of the sleeve 3 and confined loosely in position bymeans of a flanged sleeve 10, shown as having screwthreaded engagement with the sleeve 3, which sleeve is in turn held in position by a suitable lock nut 11, the distance between the outeiyedge'of the fiange-- 9 and inner
- the back end vface of the. sleeve 10 being such that the ring "also a floating movement in case the work vibrates in relation to the spindle.
- the movement of the caliper-gauge may be controlledhy the feedin mechanism which moves the grinding disc across the body 2, so that the gauge is automatically moved towards or over the bod 2 during the return movement of the grin ing disc away from the body.
- a cut-E or de-clutching device can be operatively connected with the gauge automatically to cut ofi' or arrest the feed movement of the grinding disc, when the loo 2 has attained the desired diameter, when the gauge can be moved past the body
- the mechanism above referred to is illustrated in Figs. 2 and 3 where it will be seen that a swingable frame or slide 12,
- the link 13 which is pivotally and slidahly connected between its ends to the sleeve-3 by means of a pin 13 shown by dottedlines in Figs. 2 and 3, engaging loosely" in a peripheral groove 3 in the slceve'3, is at end pivotally connected with a stationary a l5 scc ured on or forming part of the main frame of the machine.
- the link 13 At its other end the link 13 i'sa-pivotally connected with one end of the linkl t, and theother end of link 14 is pivotally connected to the slide 12.
- the link 14 is preferably made in two parts which slide-endwise relatively to each other, and are connected and normally yieldingly restrained from extension movement by means of a' spring 1 .3
- the spring and the expansiblelink 14 permit swinging movement of the slide 12 and of the grinding disk 9 over the roller even though the caliper gage cannot pass over the roller.
- Fig. 2 shows the relative positions of the parts, for instance for the commencement of the rinding operation.
- the slide 12 is assumed to be moving towards the right in Fig. 2 to carry the grinding disk 9 from.
- the electromagnet is shown as operatingoxLa pawl 19 to withdraw it when the magnet is energized, from a ratchet wheel 20 constituting an element of the main drive of the driving disk feed mechanism. Disengagement of the pawl 19 from the ratchet Wheel cuts oil or declntches the main drive from the driving apparatus and the driving operation is thereby arrested.
- Means for testing the progress of grinding operations in grinding" machines having a rotary spindle to carry the body to be ground, said means comprising a gage, an means for mounting said gage relatively to the spindle to rotate with the body to be ground, said gage being movable into gaging relation to the body to be ground.
- gage In combination with a rotary work holding device, a gage and means forinount ing said gage in relation to said device to rotate in the same dircction thereof, said gagebeing movable into and out of gaging relation to the work to gage the same.
