Magnet mounting equipment for linear motors and mounting method of magnet mounting equipment

Abstract

The invention discloses magnet mounting equipment for linear motors. The magnet mounting equipment comprises auxiliary fixing plates, magnet assembly baseplates and a positioning plate. Positioning pins are arranged on the left side and the right side of the positioning plate symmetrically. A stator baseplate is arranged in the middle of the positioning plate. A limiting baseplate is arranged on one lateral side of the stator baseplate. The magnet assembly baseplates are arranged on the upper side of the limiting baseplate. Each auxiliary fixing plate is arranged on one side, away from the stator baseplate, of the corresponding magnet assembly baseplate. A magnet is arranged in the middle of each auxiliary fixing plate. The magnet mounting equipment has the advantages that a mounting method of the magnet mounting equipment is not related to the design structure of the stator baseplate, can be applied to different dimension structures of the stator baseplate and different position relations between the magnets and the stator baseplate, and does not influence performance and application of the motors completely; during magnet mounting, position relying relations for relative assemblyof the magnets are avoided, so that accumulated errors are not generated, and uniformity in assembly is high.

Description

technical field [0001] The invention belongs to the technical field of linear motors, and in particular relates to a magnet installation device for a linear motor and an installation method thereof. Background technique [0002] Linear motor is a transmission device that converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Due to the use of "zero transmission", it has obvious advantages over traditional transmission methods, such as simple structure, no contact, and no wear. , low noise and fast speed, etc. With the improvement of industrial processing quality and motion positioning accuracy, linear motors have received extensive attention. [0003] Linear motors generally include motor rotors and motor stators. Multiple magnets need to be installed on the motor stators. Among them, the precise positioning of magnets during installation has always been one of the important reasons hindering the development of linear m...

Problems solved by technology

[0004] In order to provide a superior distribution of magnetic force lines for the linear motor, the space between adjacent magnets plays a role in isolating the magnetic force lines in the opposite direction. The existing magnet installation methods for linear motors mainly include the following three methods: 1. Process the positioning structure on the motor stator base plate, Then install the magnets one by one on the stator substrate through this positioning structure. The disadvantage of this magnet installation method is that the stator substrate is a magnetic material, and the prominent positioning structure affects the structure of the magnetic circuit, which in turn affects the performance and use of the entire motor; 2 1. Use the side of the motor stator base plate to position and install the first magnet, and then install the second magnet in sequence. In the middle, use a standard feeler gauge that meets the design interval as a limit, and install in sequence. The shortcomings of this magnet installation method are all The installation should be based on the sequence of the installation position of the first magnet. Accumulative errors will occur during the sequential installation of each magnet, resulting in uneven distribution of the final magnets, which will affect the performance and use of the motor; 3. Make a limit substrate, the middle Reserve the limit slot for magnet installation, install the limit base plate on the stator base plate first, and then install the magnets one by one. After all the magnets are installed, remove the limit base plate. The shortcomings of this magnet installation method: ①The stator is long In the application case of linear motors, the limit substrate is easy to warp and deform, which affects the assembly accuracy; ②The magnet is installed obliquely, and during the process of pushing the magnet to the limited position, the front end of the magnet will be adsorbed on the stator substrate due to the suction force, and rub the stator substrate, which will cause coating Injury; and the glue pre-applied on the stator substrate to fix the magnet and the stator substrate will be scraped off, which will affect the fixing effect of the magnet
