Two-point press crankshaft synchronization adjusting structure

Abstract

The invention discloses a two-point press crankshaft synchronization adjusting structure, which comprises a drive wheel mechanism and a driven wheel mechanism. The driven wheel mechanism comprises a bearing, a transmission shaft and a driven gear; a gear sleeve is sleeved and fixed to the circumferential direction of the transmission shaft; the driven gear is also sleeved on the periphery of the circumference of the gear sleeve; an adjusting pin is connected onto the end face of the driven gear; two adjusting screws parallel to the end face of the driven gear are arranged on the gear sleeve; the end parts of the two adjusting screws are opposite; the adjusting pin is located between the two adjusting screws; and the driven gear and the gear sleeve are connected through bolts. According to the two-point press crankshaft synchronization adjusting structure provided by the invention, the angle of the driven gear in the circumferential direction can be conveniently adjusted, the movement synchronization of two crankshafts is ensured, the two-point press crankshaft synchronization adjusting structure is convenient to adjust, high in accuracy, simple in structure, easy to process and low in manufacturing cost, the processing accuracy requirement on equipment parts is reduced, correction can be carried out to recover the processing accuracy when equipment is worn, and the maintenance and replacement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of double-point presses, in particular to a synchronous adjustment structure for crankshafts of double-point presses. Background technique [0002] The two-point press converts the rotational motion of the motor into the linear reciprocating motion of the slider through two crank-slider mechanisms, so as to shape the blank. The synchronization of the two crankshafts is the main factor affecting the accuracy of the press. The two The eccentricity error of the crankshaft is an important factor affecting the synchronization of the crankshaft. The synchronous adjustment structure of the two crankshafts of the double-point press is to reverse the processing accuracy of each part according to the final performance requirements of the press, that is, to achieve the purpose of crankshaft synchronization by improving the precision of the parts. Simply relying on improving the precision of the parts to achieve the pu...
