Description
本發明係關於一種輔助定位裝置，尤其涉及一種應用於精密加工機床中之治具輔助定位裝置。 The invention relates to an auxiliary positioning device, in particular to a fixture auxiliary positioning device applied in a precision machining machine tool.
隨著生產技術之不斷進步，精密加工技術被廣泛應用於各種生產領域，產品之加工精度要求愈來愈高，而在加工過程中各種輔助加工治具之定位精度對產品之製造精度影響非常大，因此對治具進行精確定位在精密加工技術中則顯得尤為重要，如在車削機床中，固定於機床主軸上之治具通常需要採用真空吸附之方式定位於機床主軸之端部，為保證治具與機床主軸之同軸度往往需要使用千分錶等測量儀器測量治具相對於機床主軸之偏心量，之後採用木槌等工具敲打治具進行治具與機床主軸之同軸度校正，然而上述同軸度校正方式非常費時，而且同軸度之校正精度很大程度上與測量儀器以及技術人員之技術水準有關，因此對治具之同軸度校正不夠精確，影響產品之加工精度。 With the continuous advancement of production technology, precision machining technology is widely used in various production fields, and the processing precision of products is becoming higher and higher. The positioning accuracy of various auxiliary processing fixtures in the processing process has a great influence on the manufacturing precision of the products. Therefore, the precise positioning of the fixture is particularly important in precision machining technology. For example, in a turning machine tool, the fixture fixed on the spindle of the machine tool usually needs to be positioned at the end of the spindle of the machine tool by means of vacuum adsorption. The coaxiality with the machine tool spindle often requires the use of a measuring instrument such as a dial gauge to measure the eccentricity of the jig relative to the machine tool spindle, and then the tool is used to hammer the jig to correct the coaxiality of the jig and the machine tool spindle. The degree correction method is very time consuming, and the accuracy of the coaxiality correction is largely related to the technical level of the measuring instrument and the technician. Therefore, the coaxiality correction of the fixture is not accurate enough, which affects the processing precision of the product.
有鑒於此，有必要提供一種可快速定位治具且可保證治具之同軸度之治具輔助定位裝置。 In view of this, it is necessary to provide a jig-assisted positioning device that can quickly position the jig and ensure the coaxiality of the jig.

The fixture auxiliary positioning device further comprises a centering mechanism, which is coaxially connected with the spindle and the fixture, respectively, to ensure the coaxiality between the fixture and the machine tool spindle, and the centering mechanism a cylindrical shape symmetrical along a central axis, including a front end and a rear end, the machine tool spindle includes a shaft end, the shaft end is provided with a plurality of nozzles, and a center of the shaft end is disposed coaxially with the machine tool spindle The jig includes a first surface, and a receiving hole coaxial with the jig is disposed on the first surface of the jig, and the jig is described by the first surface thereof The nozzle of the machine tool spindle is attracted to the shaft end of the machine tool spindle, and the front end and the rear end of the centering mechanism are respectively accommodated in the opening of the machine tool spindle and the receiving hole of the fixture.
