我厂生产的组合夹具的材料大都是合金钢锻件。由于锻件铣削量较大,所需夹紧力也较大,故劳动强度较高。同时平口钳和压板螺钉经常损坏。为解决上述问题,我们采用了以柱塞泵为液压源的简易液压夹具。在三年来的使用中,收到了较好效果。 液压夹具由油箱、柱塞泵、工作油缸和夹具体 I plant the production of composite fixture materials are mostly alloy steel forgings. Due to the large amount of milling forgings, the required clamping force is larger, so higher labor intensity. Flat-nose pliers and plate screws are often damaged at the same time. In order to solve the above problems, we adopted a simple hydraulic clamp with plunger pump as the hydraulic source. In three years of use, received good results.
