Description

Technical Field

[0001] The utility model relates to the technical field of piston processing, in particular to a top-type device for piston processing. Background Art

[0002] In the field of piston processing technology, the top device is a key auxiliary tool. Its main function is to push the pre-clamped piston transported into the machine tool by a robotic arm into the working area of ​​the fixture, so that the fixture clamps the piston to start processing.

[0003] For a fully automated production line, processing different piston workpieces to meet varying production requirements is inevitable. When processing these different piston workpieces, the pressing position of the push-on device on the piston often misaligns with the piston machining positioning point on the fixture chuck. This misalignment can easily cause the piston workpiece's radial centerline to not coincide with the ideal machining centerline, affecting machining accuracy, resulting in suboptimal piston machining, and even causing the piston to be scrapped. This not only reduces product quality but also significantly reduces production line efficiency.

[0004] To address this issue, current top-type devices usually require the removal of the fixing plate on the cylinder body, and the adjustment of the top pressure position of the top-type device on the piston according to the piston processing positioning point on the fixture chuck. After the adjustment is completed, it needs to be re-fixed and locked with screws. This adjustment process is relatively complicated and tedious, which is not conducive to application in large-scale production.

[0005] Therefore, there is an urgent need for a new type of piston processing pressing device that can easily and quickly adjust the pressing position of the pressing device on the piston. Utility Model Content

[0039] Please refer to the attached Figure 1 To the attached Figure 3As shown, an embodiment of the present invention provides a top-type device for piston processing. The top-type device for piston processing includes a cylinder 10, a base 20, a movable seat 30 and a buffer damper 40. Among them, the base 20 is firmly mounted on the output end of the cylinder 10; the movable seat 30 is mounted on the base 20 and is rotatable relative to the base 20; the buffer damper 40 includes a mounting end 401 and a pressing end 402 that are relatively arranged, the mounting end 401 is mounted on the movable seat 30, and the pressing end 402 is used to press the piston to be processed.
