Abstract
The utility model relates to a lathe center frame for clamping a roller, which comprises a base, wherein the base is connected with a lower frame body; the lower frame body is fixedly connected with an upper frame body through fastening pieces to form a circular body; and centering devices are uniformly distributed at the circumference of the circular body. With the adoption of the lathe center frame, supporting for the roller with the larger diameter at the middle part and the smaller diameters at the two ends can be achieved easily; an acting force of the roller on the lathe center frame is dispersed, so that a locating and supporting device is stressed uniformly; the stiffness of the lathe center frame is improved; stable and gapless rotation of the roller on the lathe center frame and on a lathe is ensured; and the cutting speed and accuracy are improved greatly.
Description
Technical field
The utility model relates to the lathe center frame field, relates in particular to a kind of lathe center frame for the clamping roll.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, and the pressure that produces when utilizing a pair of or one group of roll rolling rolls the stone roller steel.It mainly bears the Dynamic And Static Loads when rolling, the impact of wearing and tearing and variations in temperature.Existing roll and general axle class part comparison, its shape mostly is the middle part diameter of roll greater than the two ends diameter, and its weight is greater than general axial workpiece.Can't process for such roll engine lathe, need to coordinate centre frame to use, class relates to but traditional centre frame mostly is processing smallclothes axle, can't bear larger weight, therefore in the urgent need to a kind of centre frame that can adapt to this type of roll.
The utility model content
The applicant provides a kind of simple in structure for these shortcomings in above-mentioned existing production, the easy to operate lathe center frame that is used for the clamping roll, and weight capacity is good, has guaranteed the support strength of breaker roll.
The technical scheme that the utility model adopts is as follows:
A kind of lathe center frame for the clamping roll comprises base, and base is connected with lower frame, and described lower frame and upper frame are on average arranged centering machine by the affixed formation round of securing member on the circumference of described round.
Its further technical scheme is:
Described centering machine comprises turning rolls, and turning rolls is set in the inside of fairlead, and an end and the end cap of fairlead are affixed, and drive screw sequentially runs through end cap, fairlead and turning rolls; An end returning apparatus supporting device in turning rolls.
Described supporting device comprises the axle of pegging graft with turning rolls, installs respectively bearing and roller in the periphery of axle.
Described centering machine is 3, and the position is mutually on 120 ° of circumference that are arranged in round.
Described bearing is deep groove ball bearing.
The beneficial effects of the utility model are as follows:
Utilize the utility model can easily realize the supporting of the roll large to the middle part diameter, that the two ends diameter is little, the active force of roll on the utility model disperses, make locating and supporting device stressed evenly, improved rigidity of the present utility model, guarantee the steady gapless rotation of roll on the utility model and lathe, cutting speed and precision have greatly been improved, its weight capacity is good simultaneously, but load capacity is not less than the roll of 4 tons, guarantee simultaneously the support strength of roll, solved the problem that engine lathe in the past can't be processed such roll.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the work schematic diagram of the utility model clamping roll on lathe.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises base 313, base 313 is connected with lower frame 311 ', lower frame 311 ' and upper frame 313 are by the affixed formation round of securing member 310, be mutually the centering machine 3 of 120 ° on the circumference of round by guide screw 312 positions, centering machine 3 is 3.Centering machine 3 comprises turning rolls 306, and turning rolls 306 is set in the inside of fairlead 307, and an end of fairlead 307 is affixed by soket head cap screw 304 and end cap 303.Owing to all having installing hole on end cap 303, fairlead 307 and turning rolls 306, drive screw 301 runs through end cap 303, fairlead 307 and turning rolls 306 by above-mentioned installing hole and nut 302 orders, in the periphery of drive screw 301, the junction returning apparatus that is positioned at end cap 303 and fairlead 307 has thrust ball bearing 305.As shown in Figure 1, an end that is positioned at turning rolls 306 also is provided with supporting device, and supporting device comprises the axle 316 of pegging graft with roller man 306, and in periphery device bearing 308 and the roller 309 of axle 316, bearing 308 is deep groove ball bearing.
Specific works process of the present utility model is as follows:
as Fig. 1, shown in Figure 2, utilize pressing plate 304 and hang tight screw 315 the utility model is installed on Lathe bench, as shown in Figure 2, utilize the suspender roll 2 of slinging, one end of roll 2 fills house by lathe chuck, open upper frame 311 of the present utility model this moment, after by suspender, roll 2 being winched to the center of centre frame, unclamp the nut 302 of the utility model centering machine 3 this moment, rotate drive screw 301, due to being threaded of drive screw 301 and turning rolls 306, can drive thus turning rolls 306 moves back and forth in the inside of fairlead 307, after the roller 309 that utilizes lower frame 311 ' to go up centering machine 3 supports roll, movable tail frame top 4 contacts with roll 2, in order to adjust the center of roll 2, until top 4 be in same position with the center of roll 2 after, upper frame 311 is closed, fixing by securing member 310, repeat above-mentioned action and adjust the centering machine of upper frame 311, make roller 309 contact and compress roll with the periphery of roll 2, guaranteed the axiality of roll 2 with lathe chuck 1, add to rotate by lathe chuck 1 man-hour and drive roll 2 rotations, the roller 309 of the utility model centering machine 3 carries out servo-actuated, complete thus the cutting of lathe breaker roll.
Utilize the utility model can easily realize the supporting of the roll large to the middle part diameter, that the two ends diameter is little, the height of roller can be by the adjustment to drive screw, to adapt to the roll of different-diameter spindle nose.The active force of roll on the utility model disperses, make locating and supporting device stressed evenly, improved rigidity of the present utility model, guarantee the steady gapless rotation of roll on the utility model and lathe, greatly improved cutting speed and precision, its weight capacity is good simultaneously, but load capacity is not less than the roll of 4 tons, guarantee simultaneously the support strength of roll, solved the problem that engine lathe in the past can't be processed such roll.
Above-mentioned securing member 310 is comprised of screw and nut for existing known features.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to basic structure of the present utility model, the utility model can be done any type of modification.
