Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0024] according to Figure 1-6 As shown, an automatic clamping device for hydraulic cylinder processing includes a rotating table 1, a base 2 is rotatably installed on the top of the rotating table 1, a first motor 3 for driving the base 2 to rotate is fixedly installed on the side of the rotating table 1, two groups of first clamping blocks 4 are movably installed on the top of the base 2, and second clamping blocks 5 are respectively provided above the two groups of first clamping blocks 4, the first clamping blocks 4 and the second clamping blocks 5 are connected to each other by connecting rods 6, and the second clamping blocks 5 are movably installed on a lifting mechanism, and the lifting mechanism is fixedly installed on the top of the base 2.

[0025] In the above specific embodiment, when clamping the cylinder 23, the distance between the first clamping blocks 4 is adjusted to adapt to cylinders 23 of different specifications, thereby improving the versatility of the device. The first clamping block 4 and the second clamping block 5 are connected to each other by a connecting rod 6. When the first clamping block 4 is adjusted, the second clamping block 5 will be adjusted synchronously. The second clamping block 5 is driven toward the first clamping block 4 by the lifting mechanism, and the cylinder 23 is clamped and positioned by the cooperation of the first clamping block 4 and the second clamping block 5, thereby shortening the time consumed in the clamping process of the cylinder 23, thereby improving the production efficiency of the product. When adjusting the angle of the cylinder 23, the base 2 is driven to rotate on the rotating table 1 by the first motor 3, so that the angle of the cylinder 23 can be quickly adjusted, further improving the production efficiency of the product.

[0026] In this embodiment, a slide groove 7 is opened inside the base 2, and a bidirectional screw 8 is rotatably installed in the middle of the slide groove 7. Push rods 9 are respectively installed at both ends of the bidirectional screw 8. First clamping blocks 4 are fixedly installed on the top of both ends of the push rods 9. A second motor 10 is fixedly installed on the right side wall of the base 2. The power output shaft of the second motor 10 is connected to the rotating shaft of the bidirectional screw 8 through a coupling. The bidirectional screw 8 is driven to rotate by the second motor 10. Under the action of the bidirectional screw 8, the push rods 9 on both sides of the base 2 move toward each other, and the cylinder 23 is lifted by the first clamping block 4.

[0027] In this embodiment, the lifting mechanism includes a column 11, which is fixedly installed on the left and right sides of the base 2. Support plates 12 are slidably installed on the two groups of the columns 11, and cross beams 13 are fixedly installed at both ends of the bottom of the two groups of support plates 12. A third motor 14 is fixedly installed on the top of the column 11 on the left side of the base 2. A screw 15 is fixedly connected to the power output shaft of the third motor 14 through a coupling. The screw 15 is connected to the support plate 12 in cooperation with the support plate 12. The two groups of support plates 12 are connected to each other through the cross beam 13. The screw 15 is driven to rotate by the third motor 14. One group of support plates 12 moves along the column 11 under the action of the screw 15, and the other group of support plates 12 moves synchronously, so that the cylinder 23 is clamped by the second clamping block 5 in cooperation with the first clamping block 4.

[0028] In this embodiment, two groups of slides 16 are slidably installed at the bottom of the beam 13, and the two groups of slides 16 are symmetrically arranged on the beam 13. Connecting rods 6 are slidably installed on the two groups of slides 16. The bottom end of the connecting rod 6 is fixedly installed on the first clamping block 4. A second clamping block 5 is symmetrically arranged directly above the first clamping block 4. The second clamping block 5 is fixedly installed at the bottom of the slide 16. When the first clamping block 4 moves, the second clamping block 5 will be driven to move synchronously under the action of the connecting rod 6. After the first clamping block 4 lifts the cylinder 23, the third motor 14 drives the beam 13 to descend, and the slide 16 will move along the connecting rod 6, and the cylinder 23 will be clamped and positioned by the cooperation of the second clamping block 5 and the first clamping block 4.

[0029] In this embodiment, a wedge-shaped surface 17 is provided on the side wall of the first clamping block 4 close to the middle of the base 2, and a plurality of groups of longitudinally arranged anti-skid grooves 18 are opened on the wedge-shaped surface 17. The structure of the second clamping block 5 is exactly the same as that of the first clamping block 4. When the cylinder 23 is clamped by the first clamping block 4 and the second clamping block 5, the wedge-shaped surface 17 of the clamping block contacts the side wall of the cylinder 23, and the friction between the wedge-shaped surface 17 and the cylinder 23 is increased by the anti-skid groove 187, so as to prevent the cylinder 23 from sliding along the wedge-shaped surface 17 during processing.

[0030] In this embodiment, a first motor 3 is fixedly installed on the side wall of the rotating table 1, and a power output shaft of the first motor 3 is fixedly connected to a worm 19 through a coupling. A worm wheel 20 that cooperates with the worm 19 is fixedly installed on the rotating shaft of the base 2. The worm 19 is driven to rotate by the first motor 3, and with the cooperation of the worm 19 and the worm wheel 20, the base 2 rotates on the rotating table 1.

[0031] In this embodiment, an electric telescopic rod 21 is fixedly installed on the rear side wall of the base 2, and a reference plate 22 is fixedly installed on the end of the push rod 9 of the electric telescopic rod 21. The top surface of the base 2 plate abuts against the side wall of the connecting seat at the end of the cylinder 23, and the circumferential rotation of the cylinder 23 on the base 2 is limited by the base 2 plate.

[0032] The specific working process of the utility model is as follows: the rotating table is fixed on the working table of the boring and milling machine, and the staff lifts the cylinder to be processed onto the base 2 through the trolley, and then starts the second motor 10, and drives the bidirectional screw 8 to rotate through the second motor 10. Under the action of the bidirectional screw 8, the push rods 9 on both sides of the base 2 move in opposite directions, and the cylinder 23 is lifted from the base 2 through the first clamping block 4. At the same time, under the action of the connecting rod 6, the second clamping block 5 moves synchronously with the first clamping block 4, and the side wall of the end connection seat of the cylinder 23 is made parallel to the reference plate 22 by rotating the cylinder 23, and then the push rod of the electric telescopic rod 21 is extended to push the reference plate 22 to abut against the cylinder 2 3, after the position adjustment of the first clamping block 4 is completed, the third motor 10 is started, and the screw 15 is driven to rotate by the third motor 10. Under the action of the screw 15, the support plate 12 drives the crossbeam 13 to descend, and the cylinder 23 is clamped and positioned by the cooperation of the second clamping block 5 and the first clamping block 4, thereby shortening the time consumed in the clamping process of the cylinder 23, thereby improving the production efficiency of the product, and then the verticality of the cylinder end face and the spindle of the boring and milling machine is detected by a dial indicator. If the verticality does not meet the standard, the first motor 3 is used to drive the base 2 to rotate on the rotating table 1, so that the angle of the cylinder 23 can be quickly adjusted, further improving the production efficiency of the product.
