技术领域technical field
本实用新型涉及一种用于鼓式制动蹄的加工设备，尤其是一种鼓式制动蹄立卧外弧磨床。The utility model relates to a processing device for drum brake shoes, in particular to a vertical and horizontal outer arc grinding machine for drum brake shoes.
背景技术Background technique
2015年7月15日公开的“立卧式制动蹄外弧磨床”（公开号：CN2047471149U）专利，为本专利申请人申请，其包括：机架上分别设有卧式磨头、立式磨头和回转固定装置，回转固定装置包括：工件轴，工件轴的一端连接夹具，另一端连接旋转驱动电机；立式磨头包括：立式磨头垂直进给装置和立式磨头水平进给装置，立式磨头垂直进给装置上连接立式磨头总成，立式磨头总成包括：刀座，刀座内设刀轴，刀轴的一端连接刀头驱动电机；卧式磨头包括：卧式磨头水平进给装置上连接水平驱动电机和传动箱。该专利在固定装置加紧制动蹄后，由立式磨头和卧式磨头分别进行粗磨和精磨，其极大的提高了磨削的精度，有效避免了人工误差的出现，从而提高了产品的生产质量。但是立式磨头包括水平进给装置和垂直进给装置，其进给装置结构较复杂。且垂直进给装置位于机架的上方，高度较大不便于对立式磨头总成进行维护。第三，在更换垂直研磨刀盘时，需要将垂直研磨刀盘向上固定在立式磨头总成上，由于需要将垂直研磨刀盘向上举升然后再固定，往往需要机械辅助或多人才能完成更换。The patent of "Vertical and Horizontal Brake Shoe Outer Arc Grinding Machine" (publication number: CN2047471149U) published on July 15, 2015 was applied by the applicant of this patent, which includes: the frame is equipped with horizontal grinding head, vertical Grinding head and rotary fixing device, the rotating fixing device includes: workpiece shaft, one end of the workpiece shaft is connected to the fixture, and the other end is connected to the rotary drive motor; the vertical grinding head includes: vertical grinding head vertical feeding device and vertical grinding head horizontal feeding device Feeding device, the vertical grinding head assembly is connected to the vertical feeding device, and the vertical grinding head assembly includes: a knife seat, a knife shaft is installed inside the knife seat, and one end of the knife shaft is connected to the knife head driving motor; horizontal type The grinding head includes: the horizontal feeding device of the horizontal grinding head is connected with a horizontal driving motor and a transmission box. In this patent, after the fixing device tightens the brake shoes, the vertical grinding head and the horizontal grinding head perform rough grinding and fine grinding respectively, which greatly improves the grinding accuracy and effectively avoids the occurrence of manual errors, thereby improving the production quality of the product. However, the vertical grinding head includes a horizontal feed device and a vertical feed device, and the structure of the feed device is relatively complicated. And the vertical feeding device is positioned at the top of the frame, and the height is too large to be convenient for maintaining the vertical grinding head assembly. Third, when replacing the vertical grinding cutter head, it is necessary to fix the vertical grinding cutter head upwards on the vertical grinding head assembly. Since the vertical grinding cutter head needs to be lifted upwards and then fixed, it often requires mechanical assistance or multiple people. Complete the replacement.
