Embodiment Construction
[0012] Such as Figure 1 to Figure 3 As shown, a hydraulic control guide rod positioning device is provided with two guide support seats 1 in the vertical direction on the hydraulic cylinder support ear seat 6, and guide rods 2 are respectively slidably connected in the guide support seats 1, and the guide support seats 1 is provided with a positioning hole, and the positioning pin 5 is in contact with the guide rod 2 through the positioning hole; the front ends of the two guide rods 2 are connected to the front connecting plate 3, and the rear ends of the two guide rods 2 are connected to the rear connecting plate 4; On the connecting plate 4, and between the two guide rods 2, a hand wheel 9 is threadedly connected. The end of the hand wheel 9 passes through the rear connecting plate 4 and is connected with the cylinder piston rod 8 in the hydraulic cylinder block 7. The other end passes through the hydraulic cylinder support ear seat 6 and is flexibly connected with the fron...

The invention relates to a hydraulically-controlled guide rod positioning device. According to the hydraulically-controlled guide rod positioning device, two guiding bearing bases are arranged on a hydraulic cylinder support lug base; guide rods are connected in the guiding bearing bases respectively in a sliding mode; positioning holes are formed in the guiding bearing bases; positioning plug pins are contacted with the guide rods by the positioning holes; front ends of the two guide rods are connected with a front connecting plate together, and rear ends of the two guide rods are connected with a rear connecting plate together; a hand wheel is in threaded connection with the rear connecting plate, and the end of the hand wheel is connected with an oil cylinder piston rod in a hydraulic cylinder body; the other end of the hydraulic cylinder body is connected with the front end face of the hydraulic cylinder support lug base; and an oil pipe A and an oil pipe B are arranged on the hydraulic cylinder body and are connected with a hydraulic pump assembly which is arranged externally. According to the hydraulically-controlled guide rod positioning device, the advantages of smooth motion and reliable positioning in the conventional guide rod positioner are kept, and the problems of the clamping stagnation of the motion of a hand wheel screw rod pair, inconvenience for operation of space and the like which are caused by the limit of manufacturing accuracy, the long-term pollution of dust and impurities and the like are solved by the high environmental suitability of the hydraulic cylinder and the micro compressibility of hydraulic oil.
Description
technical field [0001] The invention relates to a hydraulic control guide rod positioning device, which is applied in the fields of mechanical manufacturing and mechanical processing. Background technique [0002] In the prior art, ordinary handwheel screw pairs are usually used for power drive, and it is difficult or inconvenient to perform manual operation when the operating space is small, the power demand is large, and the large stroke is in motion; in actual production, especially due to Dust particle pollution exists at the work site, which makes the secondary thread section of the screw rod mixed and stuck and difficult to clean, which seriously hinders the efficiency and quality of motion operation and product positioning. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic control guide rod positioning device, which retains the advantages of smooth movement and reliable positioning of the traditi...
