Embodiment
[0013] A hydraulic drive mechanism with linear reciprocating motion. The trolley is driven by a hydraulic cylinder. The left support shaft 3-1 and the right support shaft 3-2 are installed on the left and right sides of the drive trolley. The left support shaft is equipped with a circumferential belt. The left side round wheel 4-2 of circular groove, the right side round round wheel 4-3 that circumference has round groove is housed on the right support shaft, totally four round wheels with the same diameter, two left side round round wheels The round wheel and the two right side circular round wheels all have one on the inside of the mobile frame, and the other round wheel is on the outside of the mobile frame. The left circular wheel is in contact with the right steel wire rope, the right circular wheel is in contact with the left steel wire rope, and the right circular wheel is in contact with the left steel wire rope. There are four steel wire ropes in total. on the fixed s...

The invention belongs to the field of hydraulic drive, and particularly relates to a linearly reciprocating hydraulic drive mechanism. The linearly reciprocating hydraulic drive mechanism is characterized in that: the linearly reciprocating hydraulic drive mechanism comprises a hydraulic cylinder, a drive trolley, four support shafts, round pulleys and wire ropes, the four support shafts are respectively fixedly connected with the left and the right sides of a carriage, a round pulley is mounted on each support shaft, the circumferences of the round pulleys are provided with round grooves, one end of each wire rope is fixed on a machining tool body, the other ends of the wire ropes are fixed on a movable working table, the round grooves on the circumferences of the four round pulleys of the four support shafts are respectively in contact with the four wire ropes, the fixed points of the two wire ropes moving to the left are on the left, and round the round pulleys on the right support shafts, the fixed points of the two wire ropes moving to the right are on the right, and round the round pulleys on the left support shafts, and thereby a left pair of drive hair wires and a right pair of drive hair wires are formed. The linearly reciprocating hydraulic drive mechanism has the advantage that: the drive trolley is driven by the hydraulic cylinder, and by means of the two pairs of hair wires, the drive trolley ensures that the movable working table not only can move along with the drive trolley but also can move relative to the drive trolley. The linearly reciprocating hydraulic drive mechanism achieves the purpose of increasing the moving distance of the working table.
Description
technical field [0001] The invention belongs to the drive field of hydraulic linear motion, in particular to a hydraulic drive mechanism for linear reciprocating motion with short-stroke input and long-distance output. Background technique [0002] Reciprocating linear motion with hydraulic drive is used in a wide range of applications. In the transmission of reciprocating motion, its movement distance is the length of the cylinder piston. If it is required to increase the length of the reciprocating motion, it can only be the piston length of the large oil cylinder. It not only increases the manufacturing cost, but also lengthens the whole machine tool because the oil cylinder is too long. Leading to a decline in the comprehensive economic indicators of machine tools. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a linear reciprocating hydraulic drive mechanism, to reduce the moving ...
