كيفية اختيار موضع التركيبات المناسب

In order to ensure that the same batch of workpieces remain at the same level in the fixture, a reasonable positioning method and design must be selected. In practical applications, it is generally not allowed to directly contact the positioning base surface of the workpiece with the fixture, but the positioning is achieved by contacting the working surface on the positioning element with the positioning base surface of the workpiece. The positioning base surface and the working surface of the positioning element are collectively called the positioning pair.

1. Sufficient accuracy Since the positioning of the workpiece is completed by the contact of the positioning pair. The accuracy of the working surface of the positioning element directly affects the positioning accuracy of the workpiece, so the accuracy of the working surface of the positioning element should be relatively clear to ensure the processing accuracy requirements.

2. Sufficient strength and rigidity The positioning element should not only consider the degree of freedom of the workpiece, but also support the workpiece, bear the clamping force and cutting force. Therefore, it should also have sufficient strength and rigidity to avoid deformation problems in the application

3. Have high wear resistance The loading and unloading of the workpiece will wear the surface of the positioning element workpiece, resulting in defects on the surface of the positioning element workpiece, which will cause a decrease in positioning accuracy. When the positioning accuracy drops to the point where the processing accuracy cannot be guaranteed, the positioning element should be replaced. In order to extend the replacement cycle of positioning elements and increase the service life of fixtures, the working surface of positioning elements should have high wear resistance.

4. Good processability The structure of positioning elements should be simple, reasonable, easy to process, assemble and replace.

Only with quality can there be a market. The horizontal fixtures supplied can also be customized if necessary. The horizontal fixtures supplied by Wuxi Shunxiang Precision Machinery Co., Ltd. can be directly wholesaled in small quantities, and can also be customized if necessary.
