在光学仪器生产中,有图1所示的螺纹压卷(a),内螺纹(b)、外螺纹内锥面(c)等不同规格的螺纹压圈。材料以铝合金最多,因此铣缺口槽时,产生变形大、废品率高,如果设计专用铣槽夹具,则规格较多,工装成本较高。所以,我们设计了如图夹具。夹具结构如图2所示,钩形压板7用T形螺栓13固定在底座1上,随压圈规格不同可以调换。因工件厚度的变化,安放零件的垫板9可用调整螺母6上下调节,并用螺母5锁紧定位。夹紧是由凸轮3完成的。为防止夹紧时零件变形,因此两个钩形压板中间间距取最小值,使零件端面夹
In the production of optical instruments, thread pressure rolls (a), internal thread (b), external thread internal conical surface (c) shown in FIG. Material to the largest aluminum, so milling notch slot, resulting in large deformation, high rejection rate, if the design of milling slot fixture, the more specifications, higher tooling costs. So, we designed the picture fixture. Fixture structure shown in Figure 2, Hook plate 7 with T-bolts 13 fixed on the base 1, with the pressure ring size can be exchanged. Due to changes in the thickness of the workpiece, the mounting plate 9 parts can be adjusted with the adjustment nut 6 up and down, and locked with a nut 5 positioning. Clamping is done by cam 3. In order to prevent parts deformation when clamping, so the two hook-shaped platen to take the minimum distance between the middle, so that part of the end clip
