[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4, a replacement auxiliary device for hydraulic cylinder maintenance, comprising a workbench 1, a clamping assembly and an angle adjustment assembly, the clamping assembly comprising a first motor 2, a positive and negative thread screw 3, a bracket 4, a guide frame 5, a movable plate 6, a guide block 7, a bearing 8 and a chuck 9, two groups of brackets 4 are symmetrically arranged on the left and right sides of the workbench 1, a positive and negative thread screw 3 is also arranged between the two groups of the brackets 4, the output end of the first motor 2 passes through the bracket 4 and is connected to the positive and negative thread screw 3, the guide frame 5 is symmetrically arranged on the front and back sides of the workbench 1, two groups of symmetrically arranged movable plates 6 are also arranged on the workbench 1, a guide block 7 extending into the guide frame 5 is arranged below the movable plate 6, the movable plate 6 is threadedly connected to the positive and negative thread screw 3, a bearing 8 is embedded on the movable plate 6, the chuck 9 is fixedly connected to the inner ring of the bearing 8, and the movable plate 6 is also provided with an angle adjustment assembly that drives the chuck 9 to rotate.

[0023] During actual use, a bracket 4 is provided on the workbench 1 to support the forward and reverse threaded screw 3, the movable plate 6 is threadedly connected to the forward and reverse threaded screw 3, and the guide block 7 of the movable plate 6 is inserted into the guide frame 5 of the workbench 1 to provide stable support for it. According to demand, the motor is started, and the motor drives the forward and reverse threaded screw 3 to rotate. The two groups of movable plates 6 move toward each other to a certain position and then stop. The hydraulic cylinder is clamped by the chuck 9. Since the chuck 9 is connected to the inner ring of the bearing 8, the angle of the hydraulic cylinder can be adjusted in cooperation with the angle adjustment component.

[0024] In actual use, the angle adjustment assembly includes a second motor 10, an auxiliary plate 11, a gear 12 and a ring gear 13. The movable plate 6 is provided with an auxiliary plate 11 at one end away from the center of the workbench 1. The second motor 10 is provided on the auxiliary plate 11. The chuck 9 passes through the movable plate 6 and is provided with a ring gear 13. The output end of the second motor 10 is connected to the ring gear 13. The gear 12 is meshed with the ring gear 13. The second motor 10 drives the gear 12 to rotate under the support of the auxiliary plate 11, and the ring gear 13 drives the chuck 9 to rotate. According to the needs, the angle adjustment assembly can be set on one group of movable plates 6 or on two groups of movable plates 6. If the two groups of chucks 9 clamp the material and need to rotate the material, the electrical control is synchronized: the most direct way is to program the two groups of motors in the control system through PLC (programmable logic controller) or motion controller to ensure that the two groups of motors start at the same time when they receive the start signal. This usually involves setting the same start conditions and control logic to ensure that the two drive circuits receive the start command at the same time. In more advanced applications, a time synchronization protocol (such as EtherCAT, Profinet, etc.) can be used to ensure accurate synchronization of various control points in the network. In this embodiment, both the first motor 2 and the second motor 10 are servo motors with stable operation.

[0025] During the inspection and maintenance of the hydraulic cylinder, leakage is inevitable. For this reason, a collection frame 14 is provided between the two groups of the brackets 4. The collection frame 14 is connected to the workbench 1 in a drawer-like sliding manner. A handle 15 is provided at one end of the collection frame 14 away from the workbench 1. The collection frame 14 can be driven conveniently by the handle 15 so that the collection frame 14 can centrally collect and process the waste liquid.
