全苏工业联合公司制造出一系列工作时不排出灰尘的喷砂装置。图1的工业试验装置中,机架1上有能沿导轨2移动的带喷砂枪4的滑架3,它借助皮带5和丝杠副实现水平移动。被加工零件6夹持在夹具上,扁平零件用安装在专用托架上的磁铁板支承,夹具通过三角皮带和减速器9,由直流电动机转动。机架下部有悬浮体调制槽11,由泵12把悬浮体泵给喷砂枪。装置中部有过渡槽13,用来收集用过的悬浮体,以便循环使用。生产率为每小时30件。当对外形复杂、尺寸又特别小的零件进行喷砂时,主要的困难是它们在加工位置上很难固定。如果零件 All-Union Industrial Co., Ltd. to create a series of work does not discharge dust blasting device. In the industrial test apparatus of Fig. 1, the carriage 1 is provided with a carriage 3 with a sandblasting gun 4 which is movable along the guide rail 2 and which is horizontally moved by means of a belt 5 and a screw pair. The part to be machined 6 is clamped to the clamp, the flat part is supported by a magnet plate mounted on a special bracket, and the clamp is rotated by the DC motor through the V-belt and the decelerator 9. The lower part of the rack has a suspension modulation tank 11, and the pump 12 pumps the suspension to a sand blasting gun. The middle of the device has a transition tank 13, used to collect used suspension for recycling. Productivity is 30 pieces per hour. When blasting parts that are complex in shape and small in size, the main difficulty is that they are difficult to fix in the machining position. If parts
