Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] The invention converts the rotary motion of the motor into the rotary motion of the roller through two turns and three decelerations, so as to realize the feeding of workpieces. A plurality of rollers are respectively in contact with the two surfaces of the plate with static friction, and the rollers rotate in opposite directions to realize the linear motion of the plate. Change the magnitude of the feed static friction according to the magnitude of the applied normal pressure.
[0022] The feed power of each station is calculated according to the formula, and the power required by all stat...

The invention relates to a series-connection configurable synchronous feeding driving mechanism which comprises a prime mover assembly, a connecting mechanism and feeding module assemblies. The prime mover assembly is connected with the feeding module assemblies through the connecting mechanism. The feeding module assemblies are connected through the connecting mechanism. The prime mover assembly is connected with one end of a universal coupling in the connecting mechanism through a turbine shaft, a flat key transfers torque to tighten screws so that positioning can be achieved. The other end of the universal coupling is connected with one end of a worm in a worm and gear assembly in each feeding module assembly, and the other end of the worm of the worm and gear assembly is connected with one end of a worm of a worm and gear assembly in the next feeding module through a universal coupling. The series-connection configurable synchronous feeding driving mechanism can feed large plates, support multi-station simultaneous machining and machining feeding of the plates of different lengths, widths and heights, and adjust the number of stations. A foundation is laid for simple, efficient and flexible machining feeding of the large plates.
Description
technical field [0001] The invention relates to a feed drive mechanism of a machine tool, in particular to a feed mechanism driven by friction force, which is combined in series with feed modules, and multi-stations are processed simultaneously. Background technique [0002] In mechanical manufacturing and processing, the manufacture of a part often requires multiple processes, and each process has multiple stations. In the processing of super-long plate parts, the use of rotary table or rotary fixture makes the machine tool bulky and the mass production efficiency is low. With the continuous development of science and technology and the continuous improvement of mechanization level, super-long workpieces are used in transportation, military and other fields. It is of great significance to design a serial, combined and synchronous feed mechanism to provide a technical basis for the batch automation production of large-scale plate processing.
