Problems solved by technology
[0002] There are many types of boom parts. Due to the large size and complex shape of the workpiece, it is greatly affected by the previous welding process during the processing, and the processing involves milling and drilling of thin-walled parts, which is not easy holding
[0003] At present, it is usually processed on a special machine tool. Each specification of the workpiece corresponds to a set of special fixtures. The workpiece must be leveled and aligned before each machining, and the fixtures are heavy and difficult to disassemble and install. Therefore, the clamping time is long and the processing efficiency is low. It is difficult to meet the current customer requirements for high-efficiency clamping and processing.

The invention discloses a special fixture for arm support parts. The special fixture comprises a working table and further comprises a guide track, a plurality of sliders, a large-end part adjusting and clamping device, a small-end part adjusting and clamping device and a middle part adjusting and clamping device, wherein the guide track is fixed on the working table, the sliders are arranged on the guide track, the large-end part adjusting and clamping device is fixed on the first slider through bolts and used for adjusting and clamping the large end part of a work piece, the small-end part adjusting and clamping device is fixed on the second slider through bolts and used for adjusting and clamping the small end part of the work piece, and the middle adjusting and clamping device is fixed on the third slider through bolts and used for adjusting and clamping the middle part of the work piece. The special fixture for arm support parts can adjust and clamp work pieces, so as to achieve the purpose of sharing the same one fixture during the machining process of different specifications of arm support parts, completely solve the problem that one fixture is special for one specification of arm support parts and save the cost.
Description
technical field [0001] The invention relates to a clamping device and method for parts, in particular to a special fixture for boom parts and an adjustment method thereof. Background technique [0002] There are many types of boom parts. Due to the large size and complex shape of the workpiece, it is greatly affected by the previous welding process during the processing, and the processing involves milling and drilling of thin-walled parts, which is not easy clamping. [0003] At present, it is usually processed on a special machine tool. Each specification of the workpiece corresponds to a set of special fixtures. The workpiece must be leveled and aligned before each machining, and the fixtures are heavy and difficult to disassemble and install. Therefore, the clamping time is long and the processing efficiency is low, and it is difficult to meet the requirements of current customers for high-efficiency clamping and processing. [0004] Therefore, it is particularly impor...
