Description
Technical Field
The invention belongs to the technical field of automobile water pump manufacturing, and particularly relates to a hydraulic clamp for machining a pump body of an engine cooling water pump.
Background
At present, most of automobile engine cooling water pumps are cast, cast blanks need further processing, and when the water pump bodies are processed, the water pump bodies are fixed by using a tool clamp. Along with the development of the automobile industry, the requirement on the machining precision of the water pump body is higher and higher, and the water pump body needs to be subjected to finish machining by using numerical control machining equipment such as a machining center or a numerical control lathe, so that the water pump body needs to be accurately positioned when the water pump body is fixed by the tool clamp so as to meet the requirement on finish machining. At present, a lot of tool fixtures for fixing a water pump body still adopt a manual locking mode, for example, bolts are used for pressing the water pump body through a pressing plate, but the method has poor flexibility and low working efficiency, the consistency of manual clamping is poor, and the locking is not firm and errors occur in positioning. Therefore, a tooling clamp capable of quickly positioning and fixing the pump body of the water pump is needed.
For example, patent document CN210255279U proposes a composite machining fixture for an automobile water pump, which comprises a workbench, wherein three mutually matched pump cover clamping assemblies are assembled on the workbench; the top center of workstation is equipped with central support column, three pump cover centre gripping subassembly is around the periphery of central support column, the top of workstation be equipped with pump cover centre gripping subassembly complex pump cover extrusion subassembly, pump cover centre gripping subassembly is all including the first cylinder of assembly at the workstation top, the top of first cylinder articulates there is the stripper plate, the stripper plate can follow the flexible rotation of first cylinder, be equipped with on the workstation top with stripper plate complex cylindricality piece, the side of stripper plate and cylindricality piece cooperation centre gripping pump cover. However, the machining clamp only considers clamping and locking the pump cover, does not consider the problem of accurate positioning, cannot realize accurate positioning of the water pump cover, and cannot adopt numerical control machining equipment to perform fine machining on the water pump cover.
For another example, patent document CN107971792A proposes a clamping tool for a front cover of a volute chamber of an engine water pump, which includes a frame, wherein a mounting bottom plate is arranged on the frame, and a limiting mechanism, a pressing mechanism and an ejection mechanism are arranged on the mounting bottom plate; the limiting mechanism is fixedly arranged on the mounting base plate and comprises an inserting positioning column and a top leaning column, the inserting limiting column is used for inserting and limiting a preset through hole in the scroll chamber front cover, and the top leaning column is used for leaning against the lower bottom surface of the scroll chamber front cover. This press from both sides tight frock utilizes the through-hole grafting cooperation on spacing post of pegging graft and the volute chamber protecgulum, can realize accurate positioning, nevertheless should press from both sides tight frock and set up a plurality of spacing posts of pegging graft, all need insert the through-hole of water pump volute chamber protecgulum with the spacing post of all pegging graft when using at every turn in, therefore the location installation is inconvenient.
