Multi-station self-centering rotary clamp for bearing cap

Abstract

The invention discloses a multi-station self-centering rotary clamp for a bearing cap. The multi-station self-centering rotary clamp comprises a bridge plate, wherein a plurality of working units are arranged on the bridge plate in parallel; each working unit sequentially comprises a first hydraulic main pressing mechanism, a first hydraulic self-centering mechanism, a hydraulic auxiliary pressing mechanism, a second hydraulic self-centering mechanism and a second hydraulic main pressing mechanism; the first hydraulic self-centering mechanism comprises a self-centering oil cylinder which can be used for automatically centering and clamping workpieces; the hydraulic auxiliary pressing mechanism sequentially comprises a hydraulic swing clamping cylinder, a swing clamping cylinder pressing plate and two pressure heads; the swing clamping cylinder pressing plate is arranged at the upper end of a piston rod of the hydraulic swing clamping cylinder; the pressure heads are arranged at two ends of the hydraulic swing clamping cylinder pressing plate. According to the multi-station self-centering rotary clamp disclosed by the invention, stations are more, the production efficiency can be greatly improved, and the production cost is reduced; all processing contents can be finished by clamping the workpieces to be processed at one time, so that the processing precision is high; meanwhile, the requirement on high symmetrical degree of the workpieces can be met, and the qualification rate of the products is at least improved by 10 percent.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a multi-station self-centering rotary fixture for bearing caps. Background technique [0002] The original fixture has a large volume and is cumbersome to use, and cannot meet the requirements for the upper and lower fixtures, and cannot complete the processing at one time. The original one uses a chuck self-centering mechanism, which is bulky and the lower part of the workpiece is covered and cannot be processed. VOLVO belongs to the world's top brands, so its workpiece requirements are higher. However, traditional fixtures are not only difficult to meet the tolerance requirements of drawings, but also can only produce one fixture at a time, resulting in low production efficiency and high manufacturing costs, which seriously restrict the development of the industry. [0003] Therefore, a new fixture needs to be designed. Contents of the invention [0004] In order to solve the above...
