Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation, in particular to a quick-release bearing seat. Background Art

[0002] The bearing seat is a common component in various mechanical equipment. Its main function is to fix and support the bearing, bear the pressure, and make the shaft and the connecting parts have a certain positional relationship. A large number of bearing seats are used in the composite board production line. For example, rollers or rubber coating rollers are used in the composite board production line. These are easy-to-wear parts and need to be replaced. Since the composite board is produced continuously, the replacement of these easy-to-wear parts needs to be replaced as soon as possible. Traditional bearing seats are often difficult to disassemble and take a long time to disassemble and assemble, which affects the production efficiency of the equipment. Utility Model Content

[0008] As a preferred solution, the positioning structure includes a positioning block, which is fixed on the bearing seat body. The positioning block is provided with a positioning step raised surface, and the corresponding bearing cover is provided with a positioning groove surface that cooperates with the positioning step raised surface.

[0009] As a preferred solution, a first hinge pin is provided at one end of the bearing seat body, a support connecting rod is rotatably mounted on the first hinge pin, and the other end of the support connecting rod is hinged to one end of the bearing cover through a second hinge pin.

[0010] After adopting the above technical scheme, the effect of the utility model is as follows: due to a quick-release bearing seat, including a bearing seat body and a bearing cover, one end of the bearing cover is hinged to one end of the bearing seat body, the other end of the bearing seat is hinged with a connecting screw, the other end of the bearing cover is provided with an open slot for convenient insertion of the connecting screw, a locking screw seat is provided on the connecting screw, the locking screw seat presses the upper end surface of the open slot of the bearing cover, an operating structure for convenient operation of the locking screw seat is provided on the locking screw seat, a positioning structure for convenient positioning and matching of the bearing cover and the bearing seat is provided between the bearing seat and the bearing cover, and a locking screw seat is provided on the bearing cover There is a semicircular arc-shaped pressing surface for pressing the outer surface of the bearing, and the diameter of the pressing surface is smaller than the outer diameter of the bearing. Therefore, when disassembly is required, the worker only needs to use the operating structure to rotate the locking nut seat to loosen it, and then rotate the connecting screw to separate it from the open slot. In this way, the bearing cover can be turned over, making it convenient to replace the internal bearing. When the replacement is completed, the bearing cover and the bearing seat body can be locked and fixed by reverse operation. The quick-release bearing seat does not require the use of tools, and only needs to use the operating structure to complete disassembly and assembly. Disassembly is faster and more convenient. At the same time, the positioning structure can also make the bearing cover and the bearing seat reliably matched.

[0011] Since the operating rod is threadedly connected to the locking screw seat, a connecting screw hole is also provided on the locking screw seat, and a threaded section is provided at one end of the operating rod, and the threaded section is threadedly installed in the connecting screw hole. Therefore, when the bearing seat is used normally, the operating rod can be disassembled, which does not take up space. When disassembly and assembly are required, the operating rod can be directly threaded into the connecting screw hole, which is simple and convenient to operate.

[0012] Furthermore, since the locking screw seat includes a screw seat body, a downwardly protruding portion is provided at the bottom of the screw seat body, and a locking screw hole axially penetrating the protruding portion is provided on the screw seat body, the lower end of the protruding portion cooperates with the upper end surface of the open slot, and the connecting screw hole is provided on the screw seat body. The protruding portion can lift the screw seat body, thereby facilitating the connection of the operating rod.

[0013] Furthermore, since the positioning structure includes a positioning block, the positioning block is fixed on the bearing seat body, the positioning block is provided with a positioning step raised surface, and the corresponding bearing cover is provided with a positioning groove surface that cooperates with the positioning step raised surface. The bearing seat and the bearing cover can be accurately positioned through this positioning structure.

[0014] Since a first hinge pin is provided at one end of the bearing seat body, a support connecting rod is rotatably mounted on the first hinge pin, and the other end of the support connecting rod is hinged to one end of the bearing cover through a second hinge pin. Therefore, after adopting this structure, the support connecting rod will also be deflected when the bearing cover is opened, so that the bearing cover can be opened at a larger angle, which is more convenient for the insertion of the bearing.
