轉(zhuǎn)臺(tái)式拋丸機(jī)主要適合中小型工件的表面清理的生產(chǎn)，這規(guī)格的設(shè)備適合于發(fā)動(dòng)機(jī)連桿，齒輪，膜片彈簧等，廣泛應(yīng)用于鑄造和汽車制造業(yè)，具有生產(chǎn)效率高，密封效果好，結(jié)構(gòu)緊湊，裝卸件方便技術(shù)含量高等特點(diǎn)。為保證清理效果、提高生產(chǎn)率，在本機(jī)的設(shè)計(jì)中，采用直聯(lián)曲線葉片拋頭，而且在原有設(shè)計(jì)的基礎(chǔ)上重新調(diào)整了拋頭位置，首先拋頭與水平垂直有一定夾角，以利于工件內(nèi)腔的清理；其次轉(zhuǎn)臺(tái)支承完全改觀，便于維修、裝卸。
轉(zhuǎn)臺(tái)式拋丸機(jī)的特點(diǎn)：
(1)轉(zhuǎn)臺(tái)式拋丸機(jī)主要由室體、轉(zhuǎn)臺(tái)、傳動(dòng)系統(tǒng)、分離器、提升機(jī)、輸丸裝置、拋丸器等部分組成，在室頂一臺(tái)高速旋轉(zhuǎn)的拋丸器，對(duì)工件進(jìn)行佳方位的拋射，工件隨著轉(zhuǎn)臺(tái)轉(zhuǎn)出室體時(shí)，可直接看到清理效果，以便進(jìn)行下一步工作。
(2)通過傳動(dòng)系統(tǒng)帶動(dòng)刮丸板回轉(zhuǎn)，將丸砂通過流丸管送到提升機(jī)下部，再由提升機(jī)提到分離器進(jìn)行分離，完好的彈丸通過輸丸管及閘門供拋丸器連續(xù)使用，破碎彈丸及灰塵再分別進(jìn)入其它相應(yīng)管道，以進(jìn)行二次分離。
(3)傳動(dòng)機(jī)構(gòu)由擺線針輪減速器帶動(dòng)磨擦輪，通過一個(gè)離合機(jī)構(gòu)與轉(zhuǎn)臺(tái)發(fā)生磨擦傳動(dòng)，使轉(zhuǎn)臺(tái)平穩(wěn)轉(zhuǎn)動(dòng)。當(dāng)工件轉(zhuǎn)出室外可用于直接翻動(dòng)調(diào)整及被清理好的工件；也可隨時(shí)根據(jù)被清理工件的不同和裝卸翻動(dòng)工件的難易程度，來扳動(dòng)離合手柄，使磨擦輪和轉(zhuǎn)臺(tái)脫離，即轉(zhuǎn)臺(tái)停轉(zhuǎn)調(diào)好工件再改變手柄位置，轉(zhuǎn)臺(tái)再開始轉(zhuǎn)動(dòng)。

Rotary table type shot blasting machine is mainly suitable for small workpiece surface cleaning production, the specifications of the equipment for engine connecting rod, gear, such as diaphragm spring, widely used in casting and automobile manufacturing industry, has the advantages of high production efficiency, good sealing effect, compact structure, convenient loading and unloading of a high technological content. In order to ensure the cleaning effect, improve productivity, in the machine design, adopts a direct curve blade grinding head, and in the original design based on a realignment of the polishing head position, the first polishing head and the horizontal and vertical has a certain angle, in order to facilitate the cleaning of workpiece lumen; secondly the turntable bearing changed completely, easy to repair, loading and unloading.
Rotary table type shot blasting machine features:
(1) Rotary table type shot blasting machine is mainly composed of a chamber body, turntable, transmission system, separator, hoist, transportation pill device, shot blasting and other components, in the chamber top high-speed rotating impeller device, to carry out work on the optimum range of the projectile, the workpiece with the turntable transfer chamber body, can directly see the cleaning effect, in order to carry out the next step.
(2) Through the transmission system drives the wiper pill plate rotating balls, will flow through the pipe to the lower part of pill hoist, hoist mentioned by the separator, intact of the projectile through the transmission tube and the gate for pill Shotblast continuous use, breaking projectile and dust respectively into other corresponding pipeline, with separated for the two time.
(3) The transmission mechanism is composed of cycloid pin wheel speed reducer drives the friction wheel, through a clutch mechanism and rotary friction drive, make the turntable rotate smoothly. When the workpiece is transferred outside can be used to directly turning adjustment and is made up of the workpiece; also may at any time according to the cleaning and handling different workpieces turning workpiece difficulty level, to the clutch handle, so that the friction wheel and the turntable from the turntable stops, i.e. modulation good workpiece changing handle position, then begin to rotate the turntable.
