Description

Technical Field

[0001] The invention relates to the technical field of parts processing equipment, in particular to an automatic loading and unloading finishing machine. Background Art

[0002] There are significant bottlenecks in current metal parts finishing technology:

[0003] First, the sorting process relies on manual intervention. Traditional equipment lacks online screening capabilities, requiring manual pre-selection of qualified parts. This results in low efficiency and a high rate of missed inspections. This can lead to abnormal mold wear or equipment jamming when out-of-tolerance parts enter the finishing process.

[0004] Second, the synergy between stamping precision and lubrication is poor. Conventional single-stage stamping structures are prone to surface damage due to insufficient lubrication during high-speed operation. If an independent lubrication system is added, it is difficult to accurately control the oil volume, resulting in fluctuations in processing precision (especially when finishing at the micron level) and accelerated wear of the punch.

[0005] Third, the production process is fragmented. Loading and unloading, stamping, unloading, and counting require multiple machines to complete the process in stages. Repeated part transfers lead to cumulative positioning errors, and manual production records lead to statistical bias, which hinders automated closed-loop management.

[0006] Therefore, there is an urgent need for an automatic loading and unloading finishing machine that can solve the above problems, so as to realize the integration of the whole process of sorting-processing-output-counting, improve sorting efficiency, enhance finishing accuracy and reduce equipment wear rate.

[0038] When this solution performs automatic loading and unloading finishing, the vibrating base 14 is first activated to vibrate the sieve plate 15, causing the parts to be processed to move within the screening chamber 20.

[0039] Then, the drive shaft 27 drives the discharge push plate 28 to rotate, pushing the qualified parts in the feed channel 24 into the part stop groove 33 of the pressure base 30.
