The invention provides an ejecting type jig for grabbing workpiece. The ejecting type jig is used for grabbing the workpiece on a mold and drives the workpiece to move away from the mold under the thrust action of a plurality of pushing ejector pins of the mold in the process of ejecting the workpiece by the separated ejector pins of the mold. The jig comprises a jig plate and an ejecting mechanism, wherein a plurality of through holes are formed in the jig plate; the jig plate is arranged on a fixing mechanism; the ejecting mechanism comprises a ejecting plate, a plurality of connecting shafts and a plurality of springs; one ends of the connecting shafts are fixedly connected with one side face of the ejecting plate respectively; the other ends of the connecting shafts penetrate through the through holes in the jig plate respectively; the connecting shafts are sleeved with the springs; the two ends of each spring abut against the jig plate and the ejecting plate respectively in a loosening state; and the other side face of the ejecting plate corresponds to one face provided with the pushing ejector pins on the mold. According to the technical scheme, the ejecting plate grabs the workpiece at the beginning and then compresses the springs to drive the workpiece to move together, so that the damage to the workpiece due to the change of the relative position between the ejecting plate and the workpiece is reduced.

The invention discloses an iron filings cleaning device for mechanical processing, which comprises a frame, a hopper, a screening mechanism, an oil guide plate, an iron filings collection mechanism and a screw baffle; the hopper is erected on the frame, and a screening groove is set at the center of the hopper ;The screening mechanism is arranged on the lower side of the screening tank, and the bottom of the screening mechanism is provided with an oil guide plate and a blanking guide plate. On the contrary; the chip collecting mechanism is detachably connected with the oil deflecting plate, and the lower end of the oil guiding plate faces the feeding port of the chip collecting mechanism. In the present invention, the processed workpiece falls into the hopper and falls into the screening mechanism from the screening trough, and the iron filings on the surface of the workpiece are shaken off and separated with the operation of the screening mechanism to complete the cleaning of the workpiece surface and ensure the quality of the workpiece; After being transported to the blanking guide plate, the iron chips and cooling oil slide down from the oil guide plate into the iron filings collection mechanism, and the cooling oil is recycled to avoid environmental pollution and waste of resources.

The invention discloses an aerostatic electric spindle and a cooling device thereof. The aerostatic electric spindle comprises a shell, a sleeve, a radial bearing, a revolving shaft, a rotor and the like, wherein the inner wall of the shell is provided with at least one groove; the groove axially extends on the inner wall of the shell; the outer wall of the sleeve and the inner wall of the shell are fixed and bound; the groove forms a path for containing a coolant; the inner wall of the sleeve and the outer wall of a radial bearing are bound; the radial bearing is cylindrical; the revolving shaft is contained in the radial bearing; the radial bearing is used for forming an air film between the inner wall of the radial bearing and the revolving shaft; the revolving shaft is supported by the air film; and in addition, one end of the revolving shaft is fixedly connected with the rotor. According to the invention, the radial bearing, the revolving shaft and other components can be effectively cooled so as to avoid the problem that the precision is affected because components such as the revolving shaft and the like in the aerostatic electric spindle are subjected to thermal deformation because of lacking of the heat radiation measures to the radial bearing part.

The invention relates to the technical field of laser machining and provides a laser deburring method which comprises the following steps of: acquiring an actual outline of a workpiece and a burr outline through a workpiece image, determining a start point coordinate and an end point coordinate according to a distance between the actual outline of the workpiece and the burr outline, and cutting the burr according to the start point coordinate and the end point coordinate of the burr of the workpiece. With the adoption of the method, a part with the burr is only required to be cut, and deburring treatment is not required to be performed on the whole outline of an object, so that the deburring efficiency is improved. Simultaneously, the workpiece quality is ensured since parts without the burrs on the workpiece are not influenced by laser heat.
