Further improved technical solution, when the knife tower needs uplink, the hydraulic drive are created as the utility model The oil cylinder driving piston in dynamic portion moves down, and piston driving drive block moves down on the path that the first, second guide rail limits, Drive block moves down so that the first, second chain being fixedly connected with drive block is tensed and moved down, so that with One, the knife tower that the second chain is fixedly connected up moves.
Further improved technical solution is created as the utility model, when the knife tower needs downlink, opens solenoid valve, Pressure difference caused by self weight using knife tower, flows back into hydraulic oil in hydraulic oil container, realizes the downward movement of knife tower.
Compared to the prior art, the hydraulic counterweight device that the utility model is created is compared to traditional clump weight, greatly The weight for reducing complete machine tool keeps lathe less heavy, is easily portable and transports.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model creates hydraulic counterweight device.
Fig. 2 is the structural schematic diagram that the utility model creates another visual angle of hydraulic counterweight device.
Specific embodiment
In being described below, defining direction perpendicular to the ground is up and down direction, in the same plane, vertical with up and down direction Direction be left and right directions.Term of space correlation such as "upper", "lower", "left", "right", "top" etc. can be used herein to describe Positional relationship between element makes one element of description and the explanation of the positional relationship of another element become simple.Make herein Descriptor " parallel " is not absolute parallel, the inclination for allowing to have certain angle in mathematical meaning, in addition, in present disclosure In, when mentioning an element in another element "upper", " being connected to " or " being fixed to " another element, except non-specifically saying It is bright, otherwise the element can be directly or indirectly on another element, be directly or indirectly connected to or be fixed to that this is another A element.
Join shown in Fig. 1, Fig. 2, the utility model creation discloses a kind of hydraulic counterweight device 100, in knife tower 30 During capable and downlink, the load of 30 gravity of knife tower is balanced, reduces the load of motor and screw rod.
Join shown in Fig. 1, hydraulic counterweight device 100 includes body part 10, the hydraulic-driven portion 20 on body part 10, root The knife tower 30 moved up and down according to process requirements and the first, second chain 40 being connected between hydraulic-driven portion 20 and knife tower 30, 50。
As shown in connection with fig. 2, body part 10 substantially in a rectangular parallelepiped shape, is equipped with first end face 101 and first end face 101 is opposite Second end face 102, positioned at 101 lower end of first end face for fixed hydraulic driving portion 20 oil cylinder fixed part 11, be set to oil cylinder First, second anticollision fixed block 12 of the left and right sides of fixed part 11,13, set on 13 lower section of the second anticollision fixed block valve group 14, The first, second guide rail 15,16 for arranging vertically set on the left and right sides of oil cylinder fixed part 11 and along the vertical direction and positioned at body part 10 top is used to support the first, second counterweight support 17,18 of the first, second chain 40,50.First, second guide rail 15, 16 are parallel to each other, and in the lateral direction, the first anticollision fixed block 12 is between the first guide rail 15 and oil cylinder fixed part 11, and second Between the second guide rail 16 and oil cylinder fixed part 11, knife tower 30 is located in second end face 102 anticollision fixed block 13.Valve group 14 is wrapped Solenoid valve and hydraulic valve, electromagnetism Vavle switching both forward and reverse directions are included, hydraulic valve controls flow and flow rate.
Hydraulic-driven portion 20 includes the oil cylinder 21 on oil cylinder fixed part 11, the piston 22 in oil cylinder 21 and lives The drive block 23 that the top of plug 22 is fixedly connected.23 two sides of drive block are equipped with and the first, second guide rail 15,16 on body part 10 First, second sliding slot 231,232 of cooperation.
One end of first, second chain 40,50 is fixedly connected with the both ends of the drive block 23 in hydraulic-driven portion 20, the other end It is fixedly connected with knife tower 30.
When knife tower 30 needs uplink, the oil cylinder 21 in hydraulic-driven portion 20 drives piston 22 to move down, and piston 22, which drives, to be driven Motion block 23 moves down on the path that the first, second guide rail 15,16 limits, and drive block 23 is moved down so that with drive block 23 The first, second chain 40,50 being fixedly connected is tensed and is moved down, so that fixed with the first, second chain 40,50 The knife tower 30 of connection up moves, and the first, second anticollision fixed block 12,13 is for preventing drive block 23 from excessively moving down.Knife When tower 30 needs downlink, solenoid valve is opened, pressure difference caused by the self weight using knife tower 30 makes hydraulic oil flow back into hydraulic oil container In, realize the downward movement of knife tower 30.
The utility model replaces traditional clump weight using hydraulic counterweight device, and the weight of complete machine tool greatly reduces Amount, keeps lathe less heavy, is easily portable and transports.
