Description

Technical Field

[0002] With the continuous development of society and the continuous advancement of science and technology, mechanized, automated and standardized production has gradually become a development trend. The traditional manual production method has become increasingly unable to adapt to the development requirements of the times.

[0003] Stamping parts generally need to go through multiple different stamping processes to get finished products, and the traditional operation method is to place the stamping parts on one of the stations for stamping, and then transfer the semi-finished stamping parts to another station for stamping by manually operating the transfer equipment semi-automatically. In the process of manually and semi-automatically transferring the semi-finished stamping parts and then stamping them, a lot of time is required, which not only reduces production efficiency, but also the product accuracy cannot be well guaranteed. In particular, the transfer of large stamping parts (such as automobile panels) will consume more manpower and material resources, and the stamping accuracy will be more difficult to guarantee. Moreover, before the stamping parts are transported and loaded to the stamping equipment, if the stamping parts are not first centered and positioned, it is difficult for general loading equipment to load the stamping parts to the corresponding stamping position, resulting in low stamping accuracy.

[0004] However, when the existing automobile cover positioning and centering platform is used to center the semi-finished stamping parts, it is not convenient to adjust the clamping position according to the fixed position of the semi-finished stamping parts, resulting in that the semi-finished stamping parts are not very stable when they are centered. At the same time, since the shape of the semi-finished stamping parts is in an irregular state, the clamping plate used cannot be in contact with the semi-finished stamping parts during centering, resulting in that the positioning of the semi-finished stamping parts is not very precise. In addition, the existing device cannot quickly fix the semi-finished stamping parts according to the size of the semi-finished stamping parts, making the device not very convenient when used. In view of the above problems, it is necessary to provide a positioning and centering platform for automobile cover parts. Summary of the invention
