Description

Technical Field

[0001] The utility model relates to the technical field of vertical turntables, and particularly relates to a vertical turntable for reducing dust adhesion on the inner wall of a cam workpiece. Background Technique

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into machining and pressing. The technological process can be further divided into processes such as casting, forging, stamping, welding, machining, assembly, etc. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines, and other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequentially arranged working procedures, and one working procedure is composed of several machining steps. Especially in the machining process, for example, in the machining process of a milling machine or a grinding machine, a turntable is often required. The turntable realizes intermittent rotation of the workpiece by a certain angle to facilitate workpiece machining. The commonly used turntables are divided into horizontal turntables and vertical turntables. Due to their good structural properties and economy, vertical turntables are widely used in equipment.

[0003] After retrieval, a servo vertical turntable with the publication number CN202221935228.6 includes a main shaft and a motor arranged on the main shaft. The motor includes a rotor sleeved on the main shaft and a stator sleeved outside the rotor. The stator is sleeved with a motor housing. An upper bearing is arranged at the upper end of the main shaft, and several lower bearings are arranged at the lower end of the main shaft. The upper bearing and the several lower bearings jointly support the main shaft for rotation on the motor housing. The upper bearing is connected with a workpiece mounting plate. An encoder and a braking device are arranged in the motor housing. The braking device includes a brake disc sleeved at the lower end of the main shaft and a brake caliper for controlling the braking of the brake disc. By integrating the motor and the main shaft, the structure is simple, the transmission effect is ensured, and the disadvantages of the traditional transmission method are avoided. The encoder is used to realize the closed-loop control of the turntable. The brake disc and the brake caliper cooperate to apply an external mechanical braking force when the main shaft stops rotating, thereby greatly increasing the braking stiffness of the turntable to avoid affecting the rotation of the main shaft by external forces. When the existing vertical turntable sprays the inner wall of a cam, a large amount of powder will accumulate inside the workpiece and cannot be discharged. A large amount of dust adheres to the inside of the coating, which will not only seriously affect the coating quality, but also may cause the coating to fall off. Content of the Utility Model
