Problems solved by technology
On the one hand, in order to drive pinching or excessive resistance, the fit gap between the guide column and the sliding seat must be artificially enlarged, which systematically reduces the stamping accuracy of the precision press; on the other hand, due to the two sets of guide mechanisms Incomplete parallelism will cause hydraulic cylinder or cylinder front seals to fail prematurely due to wear
[0006] In summary, the deficiencies in the prior art can be attributed to the following: one is the low transmission precision, and the other is the short service life of the hydraulic cylinder or the front seal of the cylinder

The invention relates to the processing technology of fine presses, in particular to a self-alignment connecting device for a fine press, which comprises a guide part, a drive part and a sliding seat, wherein one end of the guide part is fixedly connected with a fixed seat; the drive part further comprises a fixed body and a movable executing element, the fixed body is fixedly connected with the fixed seat; and the sliding seat is connected with the guide part in a movable manner. The self-alignment connecting device is characterized in that a self-alignment connecting device is arranged between the executing element and the sliding seat. The self-alignment connecting device has the advantages of high transmission precision and durability.
Description
technical field [0001] The invention relates to precision press processing technology, in particular to a self-aligning connection device for a precision press. Background technique [0002] Precision presses place higher demands on the punching movement than conventional punching machines. [0003] A precision press generally includes a fixed seat, a sliding seat, and a set of guide pillars. The sliding seat can slide guided by the guide pillars. Some are crank sliders or other mechanical transmission structures. [0004] For hydraulic cylinders or cylinder precision presses, most of them have two sets of guide mechanisms, one is the aforementioned guide post and sliding seat, and the other is the guide mechanism of the hydraulic cylinder or cylinder itself. The stamping precision of the precision press is mainly determined by the precision of the sliding between the guide post and the sliding seat. [0005] In the precision presses in the prior art, the connection betwe...
