Description
Technical Field
The utility model relates to a pressure equipment frock, a rubber bush pressure equipment frock specifically says so.
Background
At present, the production mode of rubber bushings at two ends of a bottom beam body assembly of a rubber chassis suspension system is that a framework (core shaft) and rubber are vulcanized and molded, the vulcanized and molded bushings are low in rigidity, fatigue resistance and other performances, the technology is upgraded later, the rubber bushings are changed from the vulcanization molding process to a press-fitting assembly process to improve the rigidity, fatigue resistance and other mechanical performances of the rubber bushings, but a tool for press-fitting the rubber bushings and the core shaft together is lacked at present.
Disclosure of Invention
In order to solve the problem, the utility model aims at providing a rubber bush pressure equipment frock.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a rubber bush pressure equipment frock, including last pressure head, circular cone guide pillar and lower pressure head, it is the cylinder with lower pressure head main part to go up the pressure head, and go up pressure head length and be less than pressure head down, the upper and lower both ends diameter of dabber is less than the major diameter of intermediate part, and the upper end of dabber inserts in last pressure head, still be provided with the rubber bush standing groove that the diameter is greater than dabber lower extreme diameter in the upper end opening of pressure head down, bush rubber is vertical to be inserted in the rubber bush standing groove, the lower extreme of circular cone guide pillar is the hemisphere, and the upper end is provided with and is used for entangling the connection slot of dabber lower extreme, circular cone guide pillar external diameter is less than the internal diameter of bush rubber.
Furthermore, the upper end of the upper pressure head and the lower end of the lower pressure head are respectively and fixedly connected with a horizontal annular blocking edge extending outwards, the top of the upper pressure head is closed, and the lower pressure head is communicated up and down.
Further, the lower pressure head is fixed on a lower sliding block of the press-fitting machine through a bolt.
Further, the diameter of the annular retaining edge of the upper pressure head is larger than that of the annular retaining edge of the lower pressure head.
The utility model provides a rubber bush pressure equipment frock has not only improved production efficiency, and through circular cone guide pillar with the expansion of bush rubber internal diameter during pressure equipment moreover, avoid the dabber to damage bush rubber inner wall, fully guaranteed product quality.
