Abstract

The invention discloses an automatic discharge device for a back spindle. The automatic discharge device comprises an elastic chuck, an ejector pin, a chuck sleeve and a bar charge hole, wherein the ejector pin is positioned in the elastic chuck; the elastic chuck is positioned in the chuck sleeve; the ejector pin is in threaded connection with a pushing rod I; the chuck sleeve is in threaded connection with a limiting sleeve; a return spring is arranged between the elastic chuck and the limiting sleeve; one end, close to the bar charge hole, of the chuck sleeve is in contact with a pushing rod II; the other end of the pushing rod II is in contact with a short arm of an opening-closing claw; a long arm of the opening-closing claw is in contact with a pneumatic performer; an ejecting springis arranged between the elastic chuck and the bar charge hole; and one side of the bar charge hole is equipped with an inducting switch. The automatic discharge device realizes an automatic chargingfunction and an automatic discharge function of the back spindle, is simpler and more convenient to operate, and is higher in processing efficiency.

Description

technical field [0001] The invention relates to a discharge device, in particular to an automatic discharge device for a back spindle. Background technique [0002] Today, with the needs of processing, the application of back spindles on machine tools, especially CNC lathes, is becoming more and more extensive. The application of back spindles greatly reduces the clamping time of workpieces, improves the machining accuracy of workpieces, and significantly expands the processing of CNC machine tools. scope. [0003] The Chinese patent authorization announcement number is CN 2659602Y, and the utility model patent with the authorization announcement date on December 1, 2004 discloses an adjustable precision clamping spindle, including a spring chuck used to clamp the workpiece and a clamping chuck connected to the chuck. The mandrel and the support sleeve used to support the clamping mandrel, the large diameter of the clamping mandrel is fixedly connected to a main shaft head,...
