Abstract
The invention relates to a core-less grinding processing device for the external diameter of a cylindrical roller, and the device comprises two cast-iron grinding rollers, wherein the radius of one of the cast-iron grinding rollers is larger while the radius of the other cast-iron grinding roller is smaller; the circle centers of the two grinding rollers are in a same horizontal line; a gap is formed between the grinding rollers; a feeding chute is mounted above the gap; an upper pressing plate is arranged above the feeding chute; a pressing hammer is additionally arranged above the upper pressing plate; and the contact surface of the upper pressing plate and the roller is arc-shaped. The core-less grinding processing device for the external diameter of the cylindrical roller provided by the invention can be used for greatly reducing the circular deviation, increasing the linear degree, realizing the bath processing of the cylindrical roller, increasing the efficiency, reducing the processing cost and increasing the processing quality and accuracy. The upper pressing plate in the core-less grinding processing device can be moveably adjusted, thereby meeting the processing demands of the cylindrical rollers with different diameters and realizing the external diameter fine polishing processing for the cylindrical rollers in different sizes by using the same grinding device.
Description
Technical field
The present invention relates to a kind of cylindrical roller external diameter abrasive working appts.
Background technology
The use of cylindrical roller on plant equipment is very many, especially for the axial workpiece of bearing installation.Problem is, under the prior art external diameter fine finishining of cylindrical roller very complicated, and circular deviation is bigger, linearity is low, and then influences the installation of bearing.
Summary of the invention
The present invention aims to provide a cover cylindrical roller external diameter centreless grinding processing unit (plant), thereby realizes the batch machining of cylindrical roller, reduces the cost of traditional diamond-making technique, improves crudy and precision.And equipment provided by the invention can be adjusted the top board position in actual use as required, satisfying the processing request of different-diameter cylindrical roller, and reaches best processing effect.
A kind of cylindrical roller external diameter centreless grinding processing unit (plant) comprises small one and large one cast iron casting mixing roll of two radiuses, and the center of circle of two mixing rolls is on same horizontal linear; Have between the said grinding rod at interval, the top is equipped with chute feeder at interval, and the chute feeder top is provided with top board, and the top board top adds the pressurization weight, and wherein the contact-making surface of top board and roller is a circular arc.
Cylindrical roller external diameter centreless grinding processing unit (plant) provided by the invention not only can reduce circular deviation greatly, improve linearity, and can realize the cylindrical roller batch machining, raises the efficiency, and cuts down finished cost, and can improve crudy and precision.And the movable adjusting of the top board among the present invention, can satisfy the processing request of the cylindrical roller of different-diameter by structure, thereby under same equipment for grinding, realize the external diameter correct grinding processing of different size cylindrical roller.
Description of drawings
Fig. 1 is a cylindrical roller external diameter centreless grinding processing unit (plant) sketch map of the present invention;
Fig. 2 be among Fig. 1 A to schematic side view.
The specific embodiment
As illustrated in fig. 1 and 2; Cylindrical roller external diameter centreless grinding processing unit (plant) of the present invention comprises small one and large one cast iron casting mixing roll 11 and 12 of two radiuses, and wherein mixing roll 11 radiuses are big; The mixing roll 11 and 12 the two the centers of circle are on same horizontal linear; And the two is separated by a distance, and the chute feeder 4 that is used to carry cylindrical roller workpiece 6 is installed in the spacing of mixing roll 11 and 12, and the chute feeder top is provided with the top board 2 that is used to limit roller; Add the pressurization weight directly over the top board 2, auxiliary top board 2 limits cylindrical roller.Mixing roll 11 and 12 belows are connected on the motor 5, provide a power to drive its running through motor 5.
Cylindrical roller external diameter centreless grinding processing unit (plant) of the present invention adopts small one and large one two mixing roll designs, adopts the mode of top board restriction simultaneously, and cylindrical roller is ground.Wherein, top board provides grinding pressure for whole device, and plays the abrasive action of trace, and the contact-making surface of this top board and cylindrical roller is an arc surface, plays the cornerite effect, and can repair the circular deviation of cylindrical roller.Two mixing rolls have identical angular velocity of rotation; Because the two diameter is different; So the external diameter peripheral speed of the two is different; Make to produce relatively between cylindrical roller and the mixing roll and slide, because the angle adjustment of little mixing roll at vertical and horizontal level arranged, make roller feed motion to be arranged simultaneously along axis direction.Mixing roll not only can grind the effect of roller like this, can also play the effect of drive balls.
Claims (2)
1. a cylindrical roller abrasive working appts is characterized in that, comprises mixing roll (11) and (12); Have between said grinding rod (11) and (12) at interval; The top, interval of said mixing roll (11) and (12) is equipped with chute feeder (4); Said chute feeder top is provided with top board (2); Said top board (2) top adds pressurization weight (3);
Mixing roll (11) and (12) are the cast iron casting material; Between the mixing roll (11) greater than mixing roll (12); The center of circle of mixing roll (11) and (12) is on same horizontal linear; Mixing roll (11) and (12) all are connected on the motor (5).
2. cylindrical roller abrasive working appts according to claim 1 is characterized in that, said top board (2) is a circular arc with the contact-making surface of roller.
