Description

Special baffle device for workpiece flush

technical field

The steel pipe with a length of more than 3 meters is limited by the process, and its straightness will have a certain amount of deviation. In addition to the error in the installation of the bottom supporting roller mechanism, when the steel pipe rotates, the steel pipe will move in one direction, and the steel pipe will be damaged. The ratio of the grinding wheel to the forward speed makes the grinding quality unstable. In order to ensure that the steel pipe does not move, the current technology adopts a fixed baffle plate at both ends of the steel pipe to withstand the end face of the steel pipe (as shown in Figure 4). This baffle structure rotates eccentrically synchronously with the steel pipe under the thrust of the rotating steel pipe. , resulting in constant scratching, the baffle has a short life, and damage to the end of the steel pipe.

Detailed ways

Example 1

As shown in Figures 1 and 2, a special baffle device for workpiece flush, which includes a baffle body 1, a rotating shaft 2 and a frame 3, one end of the rotating shaft 2 is connected to the frame 3 through a rolling bearing (not shown in the figure) , and the other end is connected with the baffle body 1 by a key.

The baffle body 1 is in the shape of a disc as a whole, and its end face away from the frame 3 is provided with a plurality of concave spherical surfaces 11, and each concave spherical surface 11 is equipped with a working rolling body 4 that matches its size, preferably the working rolling body 4 is steel. The working rolling element 4 can roll freely on the concave spherical surface 11. In order to prevent the working rolling element 4 from falling out from the concave spherical surface 11, a rolling element pressing plate 5 is installed on the baffle body 1. The body 4 has a through hole with a small diameter, so that the working rolling body 4 is exposed to the rolling body pressing plate 5, but does not fall out and can rotate freely.

For the friction between the working rolling elements 4 and the concave spherical surface 11 , a plurality of supporting rolling elements 41 are installed between them. Preferably, the supporting rolling elements 41 are steel balls smaller than the working rolling elements 4 .

In order to make the supporting rolling element 41 and the working rolling element 4 rotate flexibly and prevent the outside dust from entering the concave spherical surface 11, a dustproof plate is installed between the baffle body 1 and the rolling element pressing plate 5). Working rolling elements 4 free rolling holes.

During operation, as shown in Figure 3, when the end of the rotating steel pipe moves to one end, it bears against the working rolling element 4 on the baffle body 1. The working rolling element 4 is subjected to the extrusion force of the steel pipe, and the working rolling element 4 In the concave spherical surface 11 of the baffle plate 1, it rotates with the supporting rolling body 41 to eliminate the pressure on the baffle body 1 from the end of the steel pipe. Sliding friction is converted into rolling friction, which protects the end of the steel pipe from damage. Since the surfaces of the working rolling element 4 and the supporting rolling element 41 have high wear resistance, and at the same time freely rotate in the concave spherical surface 11, the friction on the concave spherical surface 11 is greatly reduced. The service life of the baffle body 1 is increased.

The above-mentioned embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be realized in other ways, and any obvious replacements are within the protection scope of the present invention without departing from the concept of the technical solution. within.
