Lower grinding head tray structure of vertical grinder

Abstract

A lower grinding head tray structure of a vertical grinder comprises a tray, a frame, a gear beam barrel, a bearing pedestal and a long shaft; the tray and a grinding wheel are concentrically mounted; the external diameter of the tray is 1mm to 5 mm smaller than the internal diameter of the grinding wheel; the tray is fixed at the upper end of the long shaft; the lower end of the long shaft is fixed on the frame; a seal ring and bearings are sleeved at the upper part of the long shaft to fix the vertical part of the long shaft to be prevented from wobble; the gear beam barrel is sleeved outside the long shaft, and the seal ring and the bearings are arranged between the gear beam barrel and the long shaft; the bearings are sleeved on the outer walls at the upper part and the lower part of the gear beam barrel, and are mounted on the bearing pedestal to ensure that the gear beam barrel rotates smoothly; the grinding wheel is fixed at the upper end of the gear beam barrel; a gear is arranged at the lower end of the gear beam barrel; and when the gear transmits the torque of a motor, the grinding wheel can rotate. The tray is flush with the upper end surface of the grinding wheel, and when an abrasive disk drives parts to slide through the grinding wheel, the parts are moved to the upper end surface of a lower grinding wheel smoothly under the supporting action of the tray or the grinding wheel, and cannot fall into the gap in the middle of the gear, so that all parts are ground at the same time.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to a lower grinding head tray structure of a vertical grinding machine. Background technique [0002] Bearings (such as rollers, bearing rings), cylindrical pins, automotive (such as valve springs, clutch springs) compression springs, nozzle oil pump compression springs, etc. are the most widely used mechanical parts in mechanical equipment and automobiles. These mechanical parts not only require The two ends are parallel, the two ends are perpendicular to the axis, and the production quantity is large. At present, most of the two ends of the bearing are processed by a surface grinder. This processing method has low production efficiency because each part is not ground by the grinding wheel at the same time, and the ground parts have to be picked up manually. There is also a method of double-end grinding machine processing. A plurality of holes or sleeves suitable for the outer diamete...

Problems solved by technology

Unloading parts one by one is time-consuming and labor-intensive, which affects the production efficiency of the grinding machine

[0003] The patent application number is 201110158483.4 "the millstone parallel movement mechanism of spring grinding machine" discloses a kind of new device that can allow all parts on the whole millstone to participate in grinding at the same time, but before it is realized, it must be solved before the millstone is moved into the In the middle of the grinding wheel, when the parts pass through the gap in the middle of the grinding wheel, some parts will fall due to the loss of the support below, and this case occurred.
