Description
Technical field
The utility model relates to a kind of pay-off of lathe, and more particularly, the utility model relates to a kind of automatic feeding device for lathe that is used to carry bar or pipe material.
Background technology
Pay-off is that continuous, the operate as normal of lathe provides guarantee.For the ease of carrying the material of excellent tubulose, people have carried out long-term exploration, have proposed varied technical scheme that is applicable to steel bar automatic feeding.For example: the Chinese patent document discloses a kind of bar gripping mechanism (application number: CN02204098.6), be assembled between the head of bar feeder and automatic lathe, in order to the bar gripping mechanism of rotation amplitude of limitation bar of bar feeder.The somebody applied for the steel bar automatic feeding machine of tool lazy-tongs by name patent (application number: CN200420004795.5), for self-feeding synchronously provides possibility.
The automatic feeding structure of such scheme is comparatively complicated, fluctuation of service, and the processing to lathe impacts easily, and the conveying of bar needs more manual work to participate in.For this reason, the someone has designed a kind of numerically controlled lathe self-feeding and has clamped trip gear (application number: CN022486372), be made up of sliding sleeve, ball, slide block, handle and connecting rod, collet etc., to accomplish the clamping of bar.Through the air pressure or the liquid presses piston pole of solenoid control, reciprocation cycle operation promotes one and clamps the trip gear rectilinear motion automatically, and vertically moves slide block and move forward or backward, thereby has realized that numerically controlled lathe clamps in the front-end of spindle self-feeding.But; When real work, following situation can appear: 1, when the trombone slide inside of a bar at the chuck of lathe, when the back is put a bar again; When bar is low weight, can follow feed mechanism and move forward and backward, can't the material in the trombone slide be sent forward because of frictional force.2, during the main axis rotation of lathe,, cause the vibrations of whole device because bar can cause very big disturbance; The running accuracy and the workpiece quality of main shaft have been influenced; If adopt rigid structure to limit its disturbance, then can significantly increase the living load of lathe, even kill; The waste electric power resource, the service life of shortening lathe motor and power transmitting elements.3, clamp trip gear automatically and directly clamp the bar feeding; Owing to clamp between trip gear and the machined into cutter automatically and can't press close to operation; Keep at regular intervals, make last section of bar can't self-feeding processing, can only artificial feeding; Can reduce operating efficiency like this, increase operating personnel's labour intensity.4, feed length of bar is closed power delivery unit by trigger button and is stopped feeding and realize; Because the power delivery unit stop position receives brake effectiveness, the stability of supply voltage, the inertia of bar, the influences such as damping change of automatic feeding; Can't guarantee that scale is accurate, the utilization rate of bar is lower.
