Description
Technical Field
The utility model relates to the field of leveling clamps, in particular to a self-centering manual leveling clamp for a cylinder cover.
Background
Tight control of the thickness of the head fire face is absolutely necessary to prevent cracking when used on high output engines. Too thick a flame face can affect the heat transfer of the cooling water, resulting in a hotter flame face and an elevated operating temperature resulting in cracking from the injector orifice edge to the valve seat. Therefore, in the processing process of the cylinder cover, the size requirement from a machining plane to an inner cavity blank surface needs to be ensured. In order to ensure the machining requirement, after the thickness gauge detects, the positioning plane of the part needs to be finely adjusted so as to control the machining wall thickness difference value. The existing clamp is fixedly adjusted, supported and positioned, and the following problems are mainly generated in the actual production process:
1. under the condition of adopting fixed adjustment support three-point positioning part planes, the consistency of the blank surface of the inner cavity and the positioning plane cannot be ensured due to cylinder cover parts manufactured by different dies, so that the wall thickness detection difference value after the part processing is large in the state, and the requirement of customers cannot be met;
2. because the dead weight of the part is 76.1kg, the adjusting support is tightly meshed with the threads of the tool bottom plate under the condition that the part is not disassembled, the stress is very large, and the adjusting support cannot be adjusted. If the parts are disassembled and then adjusted, various problems exist: (1) the fit clearance between the adjusting support and the tool threaded hole is large, and the manual adjusting value is inconsistent with the actual effective adjusting value and cannot be adjusted in a reference mode. (2) The consistency of the positions of the parts before and after adjustment cannot be ensured by clamping the parts again after adjustment, and the wall thickness detection difference cannot be referred to.
Therefore, the existing clamp cannot be controlled in the processing process, the variables are too many, and after the wall thickness gauge detects, the effective adjustment cannot be formed through comparison of the values, so that the processing size is poor, the material waste is caused, the production cost is greatly increased, and the production efficiency is reduced.
