Abstract
The utility model provides a circular arc dresser which is a key component of a cut-in shaping internal grinding type grinding machines. The dresser is used for dressing the circular arc of the outer diameter of grinding wheels, and for the grinding the outer ring channel of ball bearings. The circular arc dresser comprises a diamond pen holder, a rotary oil cylinder, a bearing seat, an initial tool setting shaft, diamond pen fine turning and locking device. The double-supporting diamond pen holer is used to replace a traditional single-supporting cantilever structure to ensure enough rigidity of dressing without staggered cut with high dressing precision. Compared with traditional circular arc dressers, the utility model is additionally provided with finial top supporting initial tool setting shaft, and the diamond pen fine turning and locking device so as to regulate the dressing radius R of grinding wheels rapid and reliable.
Description
The utility model relates to a kind of grinding wheel arc dresser, and it is the critical component of mill pattern grinding machine in cut-in type is shaped, and trimmer is used for the grinding of ball bearing outer ring raceway groove to the circular arc finishing of emery wheel external diameter.
At present, the traditional structure of domestic and international the type lathe grinding wheel arc dresser is shown in figure one.It is made up of Buddha's warrior attendant penholder 2, bearing block 3,140 ° of angling cylinders 4, latch plate 5, micrometer adjusting screw 6, diamond pen 7 and locking nails 8.1 is emery wheel to be repaired, and grinding wheel diameter is D, and R is the finishing radius.It adopts cantilever rotary oscillation finishing structure, and the Buddha's warrior attendant penholder is a cantilever support, and utilizes the adjustment of micrometer adjusting screw, makes the latch plate distortion to reach the purpose of fine setting, decides the final dimensional accuracy of work piece raceway groove in the journey grinding thereby finish.
The drawback of tradition trimmer is that the golden pen frame of cantilever support itself just exists a little less than the rigidity and the problem of repairing cutter relieving.When grinding wheel diameter D was big with the finishing radius R, because cantilever is long, the problem that reflects was more obvious, can seriously reduce dressing accuracy, the coarse rill that finishing back wheel face exists will duplicate on the workpiece channel surface in grinding process fully, and crudy is obviously reduced.The finishing radius R of tradition trimmer realizes by staff's operating technology that fully special under the situation of small quantities of many specifications, it is time-consuming and difficult mixing up the finishing radius R.Traditional trimmer is in deciding the journey grinding, the distortion that utilizes micrometer adjusting screw to adjust latch plate guarantees the final size precision of work piece, because lever ratio is the relation of amplifying, micrometer adjusting screw is transferred a bit slightly, the Buddha's warrior attendant nib just moves forward and backward bigger distance, it is quite difficult wanting to be transferred to just right, if it is not enough that latch plate gives tight power, then the whole system of diamond pen un-wheeling repair is in the elastomer state, finishing can be trembleed during penetration of a cutting tool, seriously reduces dressing accuracy, and is excessive if spring gives tight power, adjustment power also can strengthen, and trace is adjusted just more difficult the grasp.
The ball bearing outer ring raceway groove grinding machine grinding wheel arc dresser that the purpose of this utility model will provide is a kind of novel, easy and simple to handle, rigidity is strong, precision is high.

The utility model is so to realize:
1. adopt dual-gripper Buddha's warrior attendant penholder.As shown in Figure 2.The Buddha's warrior attendant penholder contact ball bearing through giving tight high accuracy mounted in pairs that has respectively up and down 8. supports.The straight line oil cylinder
7. reach back shaft by piston rod, steel band and roller and 5. drive dual-gripper Buddha's warrior attendant penholder 8., make reciprocally swinging around upper and lower centre of support, to finish the circular arc finishing to emery wheel, 9. finishing nozzle simultaneously can provide sufficient cooling fluid automatically.
2. increase top initially cutter shaft and diamond pen being finely tuned and locking device of holding.As shown in Figures 2 and 3.Initial to cutter shaft diameter d=2R 4., it is intended for the scale of adjusting the finishing radius R.It by down top 1. with the last top work of adjustment that 6. holding.When needs adjustment finishing radius R, unclamp locking nail earlier 2., rotation hand wheel
3. diamond pen is retreated, abdicate the space, will 4. aim at earlier and ask cutter shaft then and press toply, aim at toply down again, make cutter shaft is contained on the back shaft centre of gyration 5. steadily.After initially cutter shaft being installed, rotation hand wheel again
To forward and backward mobile diamond pen, transfer to nib and just contacted on the cutter shaft d diameter 4., allow to use paper as thin as a wafer between nib and d diameter, to try to transfer, 2. twist locking nail dead at last.Emery wheel is repaiied in examination again, checks tool setting radius R quality, after the finishing radius R is adjusted, can utilize fine setting and locking device, realizes the accurate adjustment of trimmer diamond pen convergence emery wheel.Fine setting and locking device are by trimming hand wheel
, the fine setting push rod
, lock sleeve

Form.Middle casing
, 8. 10. upper box be connected as a single entity middle casing with the Buddha's warrior attendant penholder
Trace move and just can realize the 3. accurate adjustment of convergence emery wheel of diamond pen.The working procedure of fine setting and locking device is as carrying out: because supporting plate
Be fixed on nog plate by T type groove
On, the coarse adjustment rear supporting plate
Be motionless, and support
Be fixed by bolts on the supporting plate again, so lever
Lower end and support
At the contact point place even at the cost of one's life, when unclamping lock sleeve
And check lock lever
, the rotary fine adjustment handwheel
The time, pass through lever
Effect, make middle casing
10. 8. do the trace adjustment of convergence emery wheel with diamond pen together with upper box.Because lever ratio is bigger, the lever ratio that this device adopts is 1:3, and promptly when the rotary fine adjustment handwheel, the fine setting push rod moves bigger distance, and the displacement of diamond pen is less, therefore can realize meticulous adjustment.
Characteristics of the present utility model are:
After adopting dual-gripper Buddha's warrior attendant penholder to replace the Buddha's warrior attendant penholder of traditional single supporting cantilever structure, because 8. upper and lower of Buddha's warrior attendant penholder has the contact ball bearing through giving tight high accuracy mounted in pairs to support respectively, thereby guarantee to repair rigidity foot, cutter relieving not, dressing accuracy height.
Dual-gripper diamond pen shelf structure makes the contour adjustment simplification of Buddha's warrior attendant nib and emery wheel center, can avoid because the traditional structure level is many, and accumulated error causes the difficult difficulty of adjusting greatly.
The utility model is compared with traditional trimmer, set up top hold initially 4. to cutter shaft, make the adjustment of circular arc finishing radius R that foundation arranged, can accomplish not only accurate, not only fast but also reliable.The utility model has been equipped with fine setting and locking device again, it can make the fine setting of trimmer convergence emery wheel accurate, reliable lock, the repetitive positioning accuracy height, can satisfy machine tool feed and compensation high-precision requirement to this fine setting, in deciding the journey grinding, can increase substantially the final dimensional accuracy of work piece raceway groove, facts have proved that result of use is good.
