When adjusting, the workpiece is placed on the top of the adjustment bracket, and the workpiece can be adjusted by rotating the adjustment bracket, thus efficiently and conveniently solving the problem of grinding taper.
[0006] Specifically, the middle part of the adjustment bracket is rotatably mounted on the mounting block through a bearing, a roller is mounted on the top of the adjustment bracket, and an adjustment mechanism is arranged on the bottom. The adjustment bracket can rotate around the bearing under the action of the adjustment mechanism; the roller directly rolls in contact with the workpiece to make it adjust smoothly, and during grinding, the front end of the workpiece can rotate smoothly with the rear end of the workpiece under the action of the grinder without affecting the grinding effect.
[0007] Specifically, the adjustment mechanism includes an adjustment screw and an adjustment nut, wherein the adjustment nut is fixedly arranged on the outside of the adjustment bracket, and the adjustment screw and the adjustment nut are threadedly matched and passed through the adjustment bracket and rotatably installed on the mounting block. Rotating the adjustment screw can change the position of the adjustment nut on the adjustment screw, so that the adjustment bracket can be rotated.
[0008] Specifically, the bottom ends of the two corresponding adjustment brackets are connected by a tension spring. The tension spring acts on the bottom end of the adjustment bracket, and the upper part of the adjustment bracket always remains in an open state to facilitate the placement of the workpiece.
[0009] Specifically, the mounting block is slidably mounted on the fixed bracket, and a locking bolt is arranged on the side of the mounting block. Loosening the locking bolt can change the mounting position of the mounting block on the fixed bracket to adapt to workpieces of different lengths and improve its adaptability.
[0010] Specifically, a mounting seat is provided at the rear end of the fixed bracket, and the mounting seat is fixedly connected to the centerless grinder via bolts.
[0011] Specifically, a through groove is provided at the lower portion of the mounting block, and the fixing bracket passes through the barrel groove.
[0012] It can be seen from the above technical solution that the utility model has the following beneficial effects:
[0013] The utility model provides a quick adjustment bracket for the plunge grinder of a centerless grinder. The adjustment bracket can be rotated by adjusting the screw rod by turning the knob, so as to quickly adjust the placement position and angle of the workpiece and play a role in supporting the workpiece. The quick adjustment bracket for the plunge grinder of a centerless grinder has a simple structure, low manufacturing cost, short adjustment time and simple adjustment method, and greatly improves the grinding quality of long-axis workpieces.
