Bearing pin processing automatic machine tool
The utility model relates to a kind of device for machine tool, especially a kind of bearing pin processing automatic machine tool.
At present; Bearing pin lathe for machining work in-process can not automatic charging, automated exchanged cutter, self-tapping, discharging automatically; Material loading, discharging are wasted time and energy, and the clamping device feed is unstable, and the motor that is adopted can not be adjusted rotating speed automatically according to the performance of material; The product of producing like this, very difficult precision and the quality that guarantees product.
Summary of the invention
The purpose of the utility model is to provide a kind of simple and practical, safe and reliable bearing pin processing automatic machine tool, and it comprises pay-off, hold down gag, tapping main spindle box assembly, device for discharging, bedstead assembly, drill spindle box assembly, feed arrangement, outer cover, cooling device.Pay-off connects hold down gag; The hold down gag lower left side is provided with tapping main spindle box assembly, and bedstead assembly upper right is connected with device for discharging and drill spindle box assembly, and the middle part is provided with outer cover above the bedstead assembly; Be provided with feed arrangement in the outer cover, bedstead assembly the inside is provided with cooling device.The utility model is the fully automatic machine of automatic charging, automated exchanged cutter, automatic drilling, self-tapping, automatic discharging; Speed is fast, high efficiency, has saved process time, has alleviated labour intensity; And product processed is superior in quality, is particularly suitable for requirements of mass production.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Bearing pin processing automatic machine tool comprises pay-off 1, hold down gag 2, tapping main spindle box assembly 3, device for discharging 4, bedstead assembly 5, drill spindle box assembly 6, feed arrangement 7, outer cover 8 and cooling device 9; Pay-off 1 connects hold down gag 2; Hold down gag 2 lower left side are provided with tapping main spindle box assembly 3; Bedstead assembly 5 upper right are connected with device for discharging 4 and drill spindle box assembly 6; The middle part is provided with outer cover 8 above the bedstead assembly 5, is provided with feed arrangement 7 in the outer cover 8, and bedstead assembly 5 the insides are provided with cooling device 9.
The workflow of the utility model is: workpiece is arranged on delivery chute in order; Control by the backgauge cylinder; Receive instruction when the backgauge cylinder and automatically open, workpiece gets into through chute feeder and compresses in the counterdie, press cylinder with 2 tons pressure with firm being pressed in the upper and lower mould of workpiece.Saddle fast moving under the effect of longitudinal feed cylinder then, when workpiece will touch drill bit, saddle transformed microinching under the effect of damping in gas-liquid, and this moment, bore motor was opened the processing of holing automatically.The boring big palette fast return original position that finishes; This moment, little supporting plate was horizontal entering on the tapping station under the effect of horizontal inlet casing; Saddle fast moving under the effect of longitudinal feed cylinder again then; When workpiece soon touched tapping, saddle is microinching under the effect of gas-liquid conversion damping, carried out tapping processing.After the tapping completion of processing, the tapping motor is auto-reverse, and big palette is the fast return original position under the effect of longitudinal feed cylinder; This moment, little supporting plate moved to the centre position of boring station and tapping station under the effect of horizontal inlet casing and positioning cylinder; This moment, clamping cylinder loosened automatically, and the discharging cylinder is worked automatically, shifted workpiece onto discharging in the upper and lower mould and rested on the plate; Workpiece is being rolled on the vehicle frame through blowpit under the effect of horizontal inlet casing then, and whole procedure finishes.The supply that workpiece does not stop, the program Infinite Cyclic.
