The lower support comprises a roller and a first sliding body, the roller is arranged in a groove at the top end of the first sliding body, the roller is connected with the groove through a roller bearing, and the first sliding body is connected with a driving mechanism for enabling the first sliding body to move up and down.
The first sliding body is in threaded connection with the first screw rod, and the tail end of the first screw rod is provided with a handle for rotating the first screw rod.
And the handle and the first screw rod are in transmission through a worm and gear.
The side support comprises a roller and a second sliding body, the roller is arranged in a groove at the top end of the second sliding body, the roller is connected with the groove through a roller bearing, and the second sliding body is connected with a driving mechanism for enabling the second sliding body to move up and down.
The second sliding body is in threaded connection with the second screw rod.
The bottom of the lower support is fixedly provided with a pressing plate for fixing the central frame body.
The utility model has the beneficial effects that:
1. the utility model relates to a two-support roller type center frame, wherein a lower support is a main support, and a structure offset from the center of a main shaft is adopted to meet the stability and processing reliability of a workpiece. The side support adopts an inclined structure, so that the cutting resistance and the deflection of the workpiece are counteracted.
2. The utility model can solve the interference between the auxiliary support of the workpiece and the saddle knife rest, can meet the stability and processing reliability of the workpiece, and has simple operation, reliable work, low price and high efficiency. The integral machining precision of the machine tool is improved.

Detailed Description
Referring to fig. 1, a central frame supporting device comprises a central frame body 1, wherein a supporting surface of the central frame body 1 is an arc surface, a lower support 12 is arranged at the lower part of the central frame body 1, the lower support 12 comprises a first sliding body 2, a roller 6 is arranged in a groove at the top end of the first sliding body 2, and the roller 6 is connected with the groove through a roller bearing. The first sliding body 2 is in threaded connection with the first screw rod 3, the roller 6 moves up and down through rotating the first screw rod 3, transmission is realized between the first screw rod 3 and the handle 8 through the worm gear 4, when the handle 8 is rotated, the handle 8 drives the worm gear 4 to rotate, and then the screw rod 3 drives the sliding body 2 to adjust the first sliding body 2 to move up and down. A pressing plate 9 is fixed at the bottom of the lower support 12 and is used for fixing the central frame body 1.
The lateral part of the center frame body 1 is provided with a lateral support 13, the lateral support 13 comprises a second sliding body 10, a roller 6 is arranged in a groove at the top end of the second sliding body 10, the roller 6 is connected with the groove through a roller bearing, and the second sliding body 10 is in threaded connection with a second screw rod 11. The up-and-down movement of the second slider 10 is achieved by rotating the second screw 11.
The working process of the utility model comprises the following steps: the center frame body 1 moves along the longitudinal position of the lathe bed through the gear rack, when the two rollers 6 contact with the workpiece 7, the pressing plate 9 is fixed on the lathe bed of the workpiece through the screws, and the positioning of the utility model is realized. The worm wheel 4 is driven to rotate by the rotating handle 8 and further transmitted to the screw rod 3, the screw rod 3 rotates and then drives the sliding body 2 to move up and down, and the roller 6 is locked when the roller 6 is supported to the workpiece 7 and is coaxial with the center of the main shaft; the side support 13 drives the sliding body 10 to adjust the range by rotating the screw rod 11, and the roller 6 is locked when the roller 6 is supported to the workpiece 7 to be coaxial with the center of the main shaft. At this time, the saddle rest 5 does not interfere with the C-shaped center rest 1 when the outer circle is machined in a through-length mode.
