Abstract
The utility model discloses a roller holder mechanism for roll-threading machine, mainly comprising a base (1), a fixed bearing seat (2) and a movable bearing seat (3). The upper end and the lower and of the movable bearing seat (3) are respectively provided with a movable L-shaped press plate (4). The press plate (4) is connected with the base (1) through a bolt (5). The stress of the movable bearing seat of the utility model is homogeneous. The movable bearing seat is connected with the connected firmly. The stability is good. The connecting strength is big. The stiffness is good. The movable bearing seat is not easily deformed. The machining precision is high.
Description
Technical field:
The utility model relates to a kind of roller mount mechanism that produces part screw-rolling machines such as long bolt, bolt.
Background technology:
The roller mount of two traditional main shaft screw-rolling machines mainly is to be made of base, fixed bearing block and movable axis bearing, and the movable axis bearing is that the screw by the one side is connected with base.Because adopt screw to connect, it is little to connect contact area, connects poor rigidity, and, this syndeton has departed from the bearing block center, causes the bearing block single load bearing, so unbalance stress, poor stability, easy deformation, mismachining tolerance is big, and the product precision that processes is lower, uniformity is poor.
The utility model content:
The purpose of this utility model just is to overcome and avoid the shortcoming of prior art, and a kind of screw-rolling machine roller mount mechanism is provided, and this mechanism can make that being connected firmly of movable axis bearing and base is durable, good rigidly, converted products error are little.
The utility model screw-rolling machine roller mount mechanism mainly comprises base, fixed bearing block and movable axis bearing, and the upper/lower terminal of movable axis bearing is respectively equipped with movable L shaped pressing plate, is connected by bolt between pressing plate and base.
As a kind of improvement of the present utility model, the bottom surface of the end face of base and movable axis bearing is provided with corresponding positioning spline.
Because movable axis bearing of the present utility model is connected by between L shaped pressing plate, bolt and base, pressing plate is positioned at the two ends up and down of movable axis bearing, has increased the connection distance, and tie point is in the center of bearing block, therefore the movable axis bearing is stressed evenly, be connected firmly with base, good stability, bonding strength is big, good rigidly, not yielding, machining accuracy height, good product consistency.
Description of drawings:
Fig. 1 is for using the front view of screw-rolling machine of the present utility model.
Fig. 2 is the utility model front view shown in Figure 1.
Fig. 3 is the utility model schematic perspective view shown in Figure 1.
The specific embodiment:
As shown in Figure 1, use roller mount mechanism is installed on the fuselage 6 of screw-rolling machine of the present utility model, as Fig. 2, shown in Figure 3, roller mount mechanism mainly comprises base 1, fixed bearing block 2, movable axis bearing 3, and movable axis bearing 3 links to each other with base 1 by bolt 5, pressing plate 4, and pressing plate 4 is L shaped buckle, a face of buckle 4 is buckled on the movable axis bearing 3, another face is buckled on the base 1, and pressing plate connecting bolt 5 preferably adopts tommyhead bolt, has T-slot 15 correspondingly on base 1.To be connected better in order making between movable axis bearing and base, to increase connection stability, is that the end face of base 1 and the bottom surface of movable axis bearing 3 have corresponding positioning spline 7 at joint face, and the two connects by positioning key 71.
Claims (2)
1, a kind of screw-rolling machine roller mount mechanism, mainly comprise base (1), fixed bearing block (2) and movable axis bearing (3), it is characterized in that: the upper/lower terminal of described movable axis bearing (3) is respectively equipped with movable L shaped pressing plate (4), is connected by bolt (5) between pressing plate (4) and base (1).
2, screw-rolling machine roller mount according to claim 1 mechanism, it is characterized in that: the bottom surface of the end face of described base (1) and movable axis bearing (3) is provided with corresponding positioning spline (7).
