The invention discloses a clamp for machining of end faces of cam shafts. The clamp is used for clamping the cam shafts so that the end faces of the cam shafts can be machined. The clamp comprises a side plate and two groups of clamp bodies. The two groups of clamp bodies are used for assembly of the cam shafts and are arranged on the side plate. The assembly directions of the cam shafts on the two groups of clamp bodies are opposite. Each group of clamp bodies comprise two clamp stations. Each clamp station is provided with a stabilizing frame and two V-shaped block seats in the axial direction of the corresponding cam shaft, wherein every two V-shaped block seats are used for clamping the shaft necks at the two ends of the corresponding cam shaft. Each stabilizing frame is arranged between the two corresponding V-shaped block seats and is close to one V-shaped block. Each stabilizing frame is used for clamping the shaft necks of the corresponding cam shaft. Compared with an existing clamp for machining of the end face of the cam shaft, two groups of clamp bodies located at the head end and the tail end are combined into one group of clamp bodies, in this way, cost is reduced, and the machining efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of workpiece clamping, in particular to a clamp for machining the end face of a camshaft. Background technique [0002] At present, the fixing mode of the domestic automobile engine camshaft on its cylinder head is generally to be installed on the top of the engine cylinder head by an integral frame, and it is completed by fixing with some bolts. A half camshaft bearing hole corresponding to the cylinder head is cast on the whole frame. After the bearing hole and the corresponding bearing cover are fixed with bolts, it needs to be precisely processed to ensure that the entire camshaft hole meets the performance requirements of the engine. Generally, the bearing cover needs to be bored before finishing, and then the finishing process can be carried out; but most of the boring processes often use the general combination fixture on the machine tool to realize the clamping of the tooling, which is Operators are...
