Abstract
A center frame of roll grinder relates to a center frame structure of a machine tool, and comprises a framework, a lateral telescopic supporting mechanism and a lower telescopic supporting mechanism.The center frame is characterized in that a columnar roller is movably matched and sleeved on the excircle of a columnar pin on a U-shaped frame before the column bodies of the two telescopic supporting mechanisms, and the excircle surface of the columnar roller is higher than the U-shaped frame. The center frame has the advantages that the sliding friction is changed into the rolling abrasion, and the surface of a roller can not be damaged during the grinding of a supporting neck roller surface, thereby improving the precision.
Description
Technical field:
The utility model relates to lathe centre frame structure.
Background technology:
At present centre frame generally adopts arc watt formula centre frame on the roll grinder, and roll two ends operated by rotary motion has the supporting neck cylinder, and the centre frame arc watt contacts supporting with the roll bearing neck face of cylinder.The arc form centre frame is by frame, the side supporting device that stretches, down flexible supporting device is formed, the flexible supporting device of side is by cylinder, cylinder the place ahead U-shaped frame, the straight pin of fixing on the U-shaped frame, the arc frame of the outer fit of straight pin, screwed hole is set in the cylinder, the adjusting rod that the screwed hole internal thread connects is formed, the arc frame structure is curved of top, the below is a circular hole, this circle hole sleeve is combined on the straight pin of U-shaped frame, position-limiting action is played for the raised step cylinder in the adjusting rod middle part, the adjusting rod rear portion is the tetragonal prism that exposes, rotate for rocking arm, rely on adjusting rod to implement the flexible of cylinder with being threaded of cylinder.Down flexible supporting device by cylinder, adjusting rod, transiting rod, tiltedly carve piece and form, cylinder middle part, superstructure and the side supporting device that stretches is identical, the cylinder lower flat is fitted in one and tiltedly carves on the piece, tiltedly carve the middle part screwed hole is arranged, transiting rod front threads fit wherein, the transiting rod middle part is linked in the interior circular hole of frame, a gear is fixed in the transiting rod rear end, these gear both ends of the surface are by cod and nut longitudinal spacing, the terminal gears engaged of this gear and adjusting rod, adjusting rod other end cover merges spacing on the screwed hole of frame, and its end is a tetragonal prism.Just can implement the flexible of arc frame on the cylinder as long as shake two adjusting rod tetragonal prisms.Friction between arcwall face on the arc frame and the roll bearing neck cylinder is sliding friction.
When roll to be ground does not have supporting neck, when centre frame must be bearing on the roll exterior circular column, or workpiece is long, and when centre frame need be established in addition in the middle part, the sliding friction meeting between centre frame arcwall face and the roll cylindrical scratched roll crown.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of roll grinder centre frame is provided.
Scheme of the present utility model is: comprise frame, the flexible supporting device of side, following flexible supporting device, it is characterized in that on two flexible supporting device cylinder the place ahead U-shaped framves the straight pin cylindrical movingly fit cylindrical roller, this cylindrical roller periphery is higher than the U-shaped frame.
Advantage of the present utility model is: change sliding friction into the wearing and tearing of rolling, can not scratch roll crown when the supporting neck roll dressing, improve precision.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
Structure of the present utility model comprises frame (3), the flexible supporting device (4) of side, following flexible supporting device (5), it is characterized in that on two flexible supporting device cylinder the place ahead U-shaped framves (1) straight pin outward movingly fit cylindrical roller (2), this cylindrical roller periphery is higher than U-shaped frame (1).
Changing arc frame into cylindrical roller (2) realizes that centre frame contacts with roll and is rolling friction.
Claims (1)
1, a kind of roll grinder centre frame, comprise frame (3), the flexible supporting device (4) of side, following flexible supporting device (5), it is characterized in that on two flexible supporting device cylinder the place ahead U-shaped framves (1) straight pin outward movingly fit cylindrical roller (2), this cylindrical roller periphery is higher than U-shaped frame (1).
