Abstract
The utility model provides a third point fixed holding assembling structure for a clamping apparatus, comprising a base. The base is provided with an open first holding space, a closed second holding space and a closed third holding space. A push rod is provided between the second holding space and the third holding space, and two channels of the first holding space are communicated to the second holding space and the third holding space. In addition, both sides of the base are provided with an oil port. The two oil ports are controlled to feed oil with each other. The push rod can be driven to move, and the second holding space and the third holding space are controlled to communicate or not. Thus, the oil feeding amount in the first holding space is adjusted. The first holding space can be closed by an arresting stop apparatus. A sliding apparatus is provided with a sliding rod which is arranged in the arresting stop apparatus. The axial displacement can be controlled by the sliding rod depending on the oil amount in the first holding space. Thus, the sliding apparatus can be driven to move. The utility model has the advantages of that when two symmetric bases are arranged oppositely, the in-and-out oil amount can be controlled to drive the sliding apparatus; the work piece can obtain a stable holder between the two bases.
