The invention belongs to the technical field of watch machining, and particularly relates to rear shell grinding equipment for watch production. In order to solve the problems that existing watch rearshell grinding equipment does not have a clamping function, so that during watch rear shell grinding, a watch rear shell can be quite prone to being loosened, inconvenience is brought to the machining process, the efficiency is low, and the labor cost is increased, the following scheme is provided presently. According to the scheme, the rear shell grinding equipment comprises a fixing seat, a fixing column is fixedly arranged at the top of the fixing seat, a fixing plate is fixedly arranged at the top end of the fixing column, a fixing rod is fixedly arranged at the bottom of the fixing plate, and a fixing block is fixedly arranged at the bottom end of the fixing rod. According to the rear shell grinding equipment, the structure is simple, a watch rear shell body can be rapidly and conveniently fixed and clamped when the watch rear shell body is ground, so that shaking of the watch rear shell body is prevented, the automation is realized, the grinding quality is improved, meanwhile, different sizes or different types of grinding discs can be replaced through screws, then the different sizes and types of watch rear shell bodies can be conveniently ground, so that the requirements of people are met.
