[0027] In the Chinese patent with authorization announcement number CN211852668U, in actual use, we can know from the design drawings of the existing device that when disassembling and assembling the cylinder, it is necessary to rotate bolts and other fasteners multiple times. This practice will increase the time of the disassembly and assembly process and the workload of the staff, thereby reducing the disassembly and assembly efficiency.

[0028] See also Figure 1-6The utility model provides a technical solution: a hydraulic cylinder for a machine tool, comprising a support leg 1 for placing the hydraulic cylinder of the machine tool, a rubber plate 2 being fixed to the top surface of the support leg 1, a bottom plate 3 being fixed to the top surface of the rubber plate 2, a limit plate 4 being symmetrically fixed to the top surface of the bottom plate 3, a hydraulic cylinder body 5 being engaged between the limit plates 4, a slide groove 6 being provided on the top surface of the limit plate 4, an adjustment component 7 being provided inside the slide groove 6, the adjustment component 7 comprising a bidirectional screw rod 701, a clamping plate 702 and a first bevel gear 703, a lifting structure 8 being provided on the surface of the first bevel gear 703, the lifting structure 8 comprising a second bevel gear 801, a screw rod 802 and a bracket 803, the bracket 803 and the bottom plate 3 They are fixed to each other, and a protective component 9 is provided on the surface of the screw 802. In order to increase the stability of the hydraulic cylinder body 5 during installation, the bearing of the bidirectional screw 701 is connected to the inside of the slide 6, and the splint 702 is threadedly sleeved on the surface of the bidirectional screw 701. The splint 702 and the side wall of the hydraulic cylinder body 5 fit each other, and the end of the bidirectional screw 701 passes through the inside of the base plate 3. The first bevel gear 703 is fixed to the surface of the bidirectional screw 701, and a knob is fixed at one end of the bidirectional screw 701. The internal thread of the knob passes through a bolt, and the bolt is threadedly connected to the side wall of the base plate 3. Two first bevel gears 703 are provided, and the two first bevel gears 703 are symmetrically distributed about the longitudinal center axis of the base plate 3.

[0029] In order to facilitate the protective component 9 to be separated from the area where the hydraulic cylinder body 5 is located, and thus facilitate the disassembly and assembly of the hydraulic cylinder body 5, the second bevel gear 801 is meshed and connected to the surface of the first bevel gear 703, the screw 802 is fixed at the top center of the second bevel gear 801, and the bracket 803 is rotatably sleeved on the surface of the screw 802. The lifting structure 8 is provided with two groups, and the two groups of lifting structures 8 are symmetrically distributed about the longitudinal center axis of the base plate 3. In order to protect the hydraulic cylinder body 5 so that it will not be damaged by collision with external objects, a protective component 9 is provided. The protective component 9 includes a side plate 901 and a cover plate 902. The side plate 901 is threadedly sleeved on the surface of the screw 802, and the cover plate 902 is fixed to the surface of the side plate 901. In order to enhance the fixing effect of the hydraulic cylinder body 5, a crossbeam is provided inside the cover plate 902, and the crossbeam is in contact with the top of the hydraulic cylinder body 5.

[0030] The model of the hydraulic cylinder body 5 is HOB-40 / 1000.

[0031] Working principle or structural principle, during installation, the staff can use screws and other fasteners to fix the support leg 1 to the specified position on the machine tool surface, and then it can be used normally. During use, the rubber plate 2 will reduce the vibration amplitude, so that the device will have the function of shock absorption protection. If the hydraulic cylinder body 5 needs to be disassembled and repaired, the staff can use the knob to drive the two-way screw rod 701 to rotate, and the threads on the surface of the two-way screw rod 701 will drive the splint 702 to move away from each other, thereby releasing the clamping fixation of the hydraulic cylinder body 5. While the two-way screw rod 701 drives the splint 702 to move, it will also drive the screw rod 802 to rotate through the first bevel gear 703 and the second bevel gear 801. Because the screw rod 802 is threadedly connected to the side plate 901, when the screw rod 802 rotates, it will drive the side plate 901 and the surface cover plate 902 to rise, thereby exposing the hydraulic cylinder body 5, making it convenient for the staff to dismantle.

[0032] In summary, the device has the advantages of shock absorption and protection and convenient disassembly and assembly.
