Description
Technical field
The utility model belongs to the cylindrical roller processing unit (plant) in industrial production, especially a kind of precision machine tool main shaft bearing
Cylindrical roller grinding device.
Background technique
The superfinishing of cylindrical roller is the skin processing for realizing micro cutting to roller by the reciprocating motion of oilstone
Method, due to not only needing also to need to roller axial pressure reciprocating motion in processing.The reciprocating motion of high frequency is to entire
The stability requirement of equipment is very high, the unstable loss that can all lead to lathe of any position of lathe, so that the dimension of lathe
It is high to protect cost.Simultaneously because shutting down the decline for also resulting in production efficiency caused by maintenance.
Utility model content
To solve the above problems, the utility model provides, one kind is stable, can guarantee the accurate machine of processing for a long time
Bed main shaft bearing cylindrical roller grinding device.
In order to achieve the above object, precision machine tool main shaft bearing cylindrical roller grinding device designed by the utility model,
Including pedestal, pedestal is equipped with front guide roll and rear deflector roll, is chute feeder between front guide roll and rear deflector roll, is additionally provided on pedestal vertical
Column, column are equipped with guide rail, and guide rail is equipped with liftable rack, is equipped with reciprocating mechanism, the reciprocal fortune in rack
Cantilever is connected on motivation structure, oilstone clamping device is arranged in cantilever bottom, and chute feeder is arranged in the oilstone clamping device
Surface；The reciprocating mechanism includes the sliding rail and sliding block being laterally arranged, and sliding rail is fixed with rack, and cantilever and sliding block are solid
It is fixed, and pressure spring is equipped between the both ends and rack of the sliding block.The characteristics of this structure is that sliding block is moved back and forth bring
Vibration passes to rack by pressure spring, so that reciprocating reversing is more gentle, while limiting the movement position of sliding block, improves lathe
Working time.
Further embodiment is to be the sliding block equipped with motor, and the motor is equipped with eccentric wheel.Pass through bias
Wheel moves back and forth to realize, mechanism is simple, easy to maintain.
Another implementation is, the sliding block it is upper and lower it is monosymmetric be fixed with rack gear, be fixed with horse in rack
It reaches, the output end of motor connects the cambered sector gear less than 100 °, and sector gear can be engaged with the rack gear.Pass through fan
Motor can be directly anchored in rack by the cooperation of shape gear and upper and lower rack gear, to reduce the load on cantilever, be provided reciprocal
The stability of movement.Due to the effect of the pressure spring at cooperation both ends, rigidity when rack-and-pinion is engaged for the first time when can be reduced commutation is touched
It hits, to reduce the loss of sector gear.
Compared with prior art, precision machine tool main shaft bearing cylindrical roller grinding device designed by the utility model leads to
The use of pressure spring is crossed, so that the part energy moved back and forth is stored in pressure spring, is made in the case where not reducing motion frequency
It must commutate more smooth gentle.Different reciprocating drive mechanisms is designed simultaneously, is further cooperated with pressure spring, equipment damage is reduced
Consumption reduces use cost, improves the time of continuous service, is finally reached the purpose for improving production efficiency.
Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of embodiment.
Fig. 2 is the structural schematic diagram of 1 reciprocating mechanism of embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment 1.
As shown in Figs. 1-2, the precision machine tool main shaft bearing cylindrical roller grinding device of the present embodiment description, including pedestal 1,
Pedestal 1 is equipped with front guide roll 2 and rear deflector roll 3, is chute feeder 4 between front guide roll 2 and rear deflector roll 3, is additionally provided with column 5 on pedestal 1,
Column 5 is equipped with guide rail, and guide rail is equipped with liftable rack 6, is equipped with reciprocating mechanism 7, the reciprocal fortune in rack 6
Cantilever 8 is connected on motivation structure 7, oilstone clamping device 9 is arranged in 8 bottom of cantilever, and the oilstone clamping device 9 is arranged in feeding
The surface of slot 4；The reciprocating mechanism 7 includes the sliding rail 10 and sliding block 11 being laterally arranged, and sliding rail 10 and rack 6 are solid
Fixed, cantilever 8 and sliding block 11 are fixed, and pressure spring 12 is equipped between the both ends and rack 6 of the sliding block 11.The sliding block 11
It is monosymmetric up and down to be fixed with rack gear 13, motor 14 is fixed in rack 6, the output shaft of motor 14 passes through sliding rail 10 and sliding block
11, and export the tip of the axis and be connected with the sector gear 15 that arc length is 90 °, sector gear 15 can be engaged with the rack gear, together
The sliding block 11 of Shi Suoshu is equipped with the output shaft that slotted hole 16 makes way for motor 14.Turning for sector gear 15 is driven by motor 14
It is dynamic, so that being engaged respectively with upper and lower rack gear 13 in the time that sector gear 15 rotates a circle, to realize 15 turn one of sector gear
Mono- process back and forth formed of Zhou Shixian.And since 15 arc length of sector gear only has 90 °, time for being engaged with upper and lower rack gear 13
It is the period of a quarter, within the off time that sector gear 15 is engaged with rack gear 13, is realized by the elasticity of pressure spring 12
The commutation of reciprocating motion, while but also the fatigue point of the tooth of sector gear 15 is evenly distributed on gear.
Embodiment 2.
The present embodiment description precision machine tool main shaft bearing cylindrical roller grinding device, described in reciprocating mechanism 7
