Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a hydraulic device that is easy to maintain. Background Technology

[0002] A hydraulic press is a machine that operates on the principle of hydraulic transmission. It mainly consists of a power system, an execution system, and a control system. A hydraulic pump converts the mechanical energy of an electric motor into hydraulic energy, which is then transmitted through pipelines to the hydraulic cylinder to generate linear pressure. It is used in metal forging, stamping, press fitting, and other processing applications, and is characterized by high pressure, high precision, and a high degree of automation.

[0003] Traditional hydraulic presses typically connect the hydraulic cylinder to the equipment using bolts. While this connection is simple and stable, it can easily loosen over time, causing the pressing surface to tilt and reducing hydraulic accuracy. Furthermore, repairing the hydraulic cylinder requires disassembling multiple bolts, which is time-consuming and labor-intensive. Reinstallation also requires repeated operations, significantly reducing operational efficiency. In addition, repeated disassembly can cause wear at the bolt connections, reducing the equipment's durability.

[0004] Based on this, a hydraulic device that is easy to maintain is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic device that is easy to maintain in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydraulic device that is easy to maintain includes a hydraulic cabinet, a hydraulic pump connected to the hydraulic cabinet, a hydraulic cylinder connected to the hydraulic pump via a pipeline, a control console and a workbench connected to the hydraulic cabinet, a connecting plate connected to the workbench via a connecting column, the hydraulic cylinder connected to the connecting plate, a pressing plate connected to one end of the hydraulic cylinder, and a fixing mechanism for fixing the hydraulic cylinder connected to the connecting plate.

[0008] Preferably, the fixing mechanism includes a clamping plate, which is rotatably connected above the connecting plate. The clamping plate is rotatably connected to an abutment plate by bolts, and the lower end of the abutment plate abuts against a hydraulic cylinder.

[0009] Preferably, a hinge frame is connected to the upper end of the connecting plate, a deflection block is rotatably connected to the hinge frame, and the clamping plate is rotatably connected to the deflection block through the hinge frame.

[0010] Preferably, the deflection block is connected to a circular hole block, the clamping plate is connected to a pressing block via a spring, and the pressing block is connected to an insertion rod.

[0011] Preferably, the connecting plate has a cylinder groove, the hydraulic cylinder is placed on the cylinder groove, and a placement block is connected to the outside of the hydraulic cylinder.

[0012] Preferably, the connecting plate has a slot, and the lower end of the abutment plate is inserted into the slot.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a clamping plate structure, which uses the clamping plate to limit the hydraulic cylinder, thereby improving the connection firmness of the hydraulic cylinder and ensuring that the hydraulic cylinder can be stably connected in the cylinder groove. The abutment plate further limits the hydraulic cylinder and the clamping plate, thereby improving the connection stability.

[0015] 2. This application adopts a plug-in structure, which can quickly limit the clamping plate by plugging in the plug, so that the deflection block remains in a vertical state. This connection structure can be quickly disassembled by pressing the pressing block, and only two bolts are needed to fix the hydraulic cylinder, which facilitates the maintenance of the hydraulic cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A hydraulic device that is easy to maintain includes a hydraulic cabinet 1, a hydraulic pump 2 connected to the hydraulic cabinet 1, a hydraulic cylinder 3 connected to the hydraulic pump 2 via a pipeline 4, a control console 7 and a workbench 5 connected to the hydraulic cabinet 1, a connecting plate 8 connected to the workbench 5 via a connecting column 6, the hydraulic cylinder 3 connected to the connecting plate 8, a pressing plate 9 connected to one end of the hydraulic cylinder 3, and a fixing mechanism for fixing the hydraulic cylinder 3 connected to the connecting plate 8.

[0025] Specifically, such as Figure 3 As shown, the fixing mechanism includes a clamping plate 11, which is rotatably connected above the connecting plate 8. When fixing the hydraulic cylinder 3, the two clamping plates 11 abut against the outside of the hydraulic cylinder 3. The clamping plate 11 is rotatably connected to an abutment plate 10 by bolts 18. The lower end of the abutment plate 10 abuts against the hydraulic cylinder 3. By abutting against the lower end of the abutment plate 10, the operation of fixing the hydraulic cylinder 3 in the cylinder groove 14 is completed. The lower end of the abutment plate 10 is limited by the slot 15, and the upper end is limited by the clamping plate 11 by bolts 18.

[0026] Specifically, such as Figure 3 As shown, a hinge frame 13 is connected to the upper end of the connecting plate 8, and a deflection block 16 is rotatably connected to the hinge frame 13. The clamping plate 11 is rotatably connected to the deflection block 16 through the hinge frame 13. After the hydraulic cylinder 3 is fixed, the deflection block 16 will be in a vertical state.

[0027] Specifically, such as Figure 4 As shown, a circular hole block 17 is connected to the deflection block 16, and a pressing block 20 is connected to the clamping plate 11 via a spring 21. A plug rod 19 is connected to the pressing block 20. A through hole is provided on the circular hole block 17. When the pressing block 20 is pressed upward, the plug rod 19 will separate from the circular hole block 17, and the connection limit of the clamping plate 11 will be canceled.

[0028] Specifically, such as Figure 3 As shown, a cylinder groove 14 is provided on the connecting plate 8, and the hydraulic cylinder 3 is placed on the cylinder groove 14. A placement block 12 is connected to the outside of the hydraulic cylinder 3. The lower end of the abutment plate 10 is in contact with the upper end of the placement block 12. The abutment plate 10 is pressed down to restrict the movement of the hydraulic cylinder 3.

[0029] Specifically, such as Figure 3 As shown, a slot 15 is provided on the connecting plate 8, and the lower end of the abutment plate 10 is inserted into the slot 15. The slot 15 is used to limit the lower end of the abutment plate 10 and prevent the abutment plate 10 from shifting position.

[0030] In summary, the hydraulic device provided in this embodiment is easy to maintain. When the hydraulic cylinder 3 needs to be assembled, the hydraulic cylinder 3 can be placed in the cylinder groove 14, the deflection block 16 can be moved from a horizontal state to a vertical state, so that the clamping plate 11 is connected to the outside of the hydraulic cylinder 3, the pressing block 20 can be pressed, so that the insertion rod 19 is inserted into the round hole block 17, the pressing block 20 can be released, and the connection state of the insertion rod 19 can be stabilized by the spring 21.

[0031] Then, the abutment plate 10 is connected to the slot 15, and the upper end of the abutment plate 10 is fastened to one end of the clamping plate 11. Bolt 18 is connected at the joint. Bolt 18 does not play a fixing role, but only a limiting role. Therefore, the connection is completed after the bolt 18 is connected. There is no need to tighten the nut. After the connection is completed, the connection of the hydraulic cylinder 3 structure is completed.

[0032] When the hydraulic cylinder 3 needs to be repaired, only two bolts 18 need to be removed and the pressing block 20 needs to be pressed to quickly disassemble the hydraulic cylinder 3, which improves the convenience of repair. Compared with the traditional structure that requires the removal of a large number of bolts 18 to repair the hydraulic cylinder 3, the repair time is greatly reduced.

[0033] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
