在机床修理过程中,经常需要调换拖板楔铁,我们可以用图中所示夹具加工拖板楔铁。它可以达到既快又好的目的,大大地减少了钳工的铲刮量。从左视图中可看出,夹具右边可加工楔铁1∶50或1∶100斜度面,斜面垫铁2可按标准1∶50或1∶100斜度事先调整好,可用定位销3固定,楔铁厚度尺寸可按拖板装配后实测控制、夹具左边可加工楔铁的燕尾角,△型垫铁的截面如放大图所示,与夹具吻合角为60°,而燕尾角做成55°。如果楔铁较长,伸出部分可用小千斤顶顶住,以防加工变形。
In the machine repair process, often need to change the wedge iron wedge, we can use the fixture shown in the wedge wedge processing iron. It can achieve fast and good purpose, greatly reducing the fitter’s scraping amount. As can be seen from the left view, the right side of the fixture can be processed wedge iron 1:50 or 1: 100 slope surface, the bevel 2 can be adjusted according to the standard 1:50 or 1: 100 slope can be fixed pin 3 , The thickness of the wedge iron can be measured and controlled after the pallet assembly. The left side of the fixture can be processed with the dovetail angle of the wedge iron. The cross section of the △ horn is enlarged as shown in the figure, the angle of coincidence with the fixture is 60 °, °. If the wedge iron longer, protruding part of the jack can withstand a small jack to prevent deformation.
