DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0024] Depend on Figure 1-4 The utility model provides a pressing device for processing a hydraulic oil filter cartridge, comprising a cylinder 10, a pressure plate 20 and a riveting mechanism 30. The pressure plate 20 is fixed at the front end of the cylinder 10 and is used to press the filter cartridge cover 40 to the outer side of the end of the filter cartridge 50. The riveting mechanism 30 is arranged on the surface of the pressure plate 20 and is used to rivet the filter cartridge cover 40 and the filter cartridge 50. Pressing the filter cartridge cover 40 to the end of the filter cartridge 50 by the pressure plate 20 is a prior art. Different from the prior art, the utility model is further provided with a riveting mechanism 30 on the pressure plate 20 for processing a hydraulic oil filter cartridge. The riveting mechanism 30 can be used to rivet the wall surface of the filter cartridge cover 40 and the wall surface of the filter cartridge 50 together, thereby preventing the filter cartridge cover 40 from falling off.

[0025] In this embodiment, the riveting mechanism 30 includes a protruding block 31 fixed on the surface of the pressure plate 20, a riveting punch 32 horizontally slidably arranged on the side of the protruding block 31, and a driving mechanism 33 arranged in the protruding block 31 for driving the riveting punch 32 to move. The diameter of the protruding block 31 is smaller than the diameter of the through hole on the filter cartridge cover 40. When in use, the filter cartridge cover 40 is first aligned with the end of the filter cartridge 50, and then the pressure plate 20 is driven by the oil cylinder 10 to press the filter cartridge cover 40 down to the outside of the end of the filter cartridge 50. At the same time, the protruding block 31 enters the filter cartridge 50, and the riveting punch 32 is driven to move outward by the driving mechanism 33, so that the side wall of the filter cartridge 50 is deformed outward and riveted to the inner wall of the filter cartridge cover 40, so that the filter cartridge cover 40 is firmly limited at the end of the filter cartridge 50 to prevent loosening and falling off.

[0026] In some embodiments, the driving mechanism 33 includes a movable groove 331 arranged in the protruding block 31, a return spring 332 connected between the movable groove 331 and the riveting punch 32, and an oil inlet pipe 333 connected to the movable groove 331. The movable groove 331 is horizontally arranged, and its length direction points to the center of the circle of the protruding block 31. The riveting punch 32 is slidably arranged in the movable groove 331. The oil inlet pipe 333 is used to connect hydraulic oil. Hydraulic oil is introduced into the movable groove 331 through the oil inlet pipe 333, which can push the riveting punch 32 to slide outward and punch the inner wall of the filter cartridge 50, so that the wall surface of the filter cartridge 50 is riveted with the wall surface of the filter cartridge cover 40.

[0027] In some embodiments, the oil cylinder 10 includes an oil cylinder body 11, oil inlet joints 12 connected to both ends of the oil cylinder body 11, and a hydraulic rod 13 movably disposed in the oil cylinder body 11. The hydraulic rod 13 is fixed with a piston, and the piston divides the interior of the oil cylinder body 11 into the following parts: Figure 1 The chambers Ⅰ and Ⅱ shown in the figure, the pressure plate 20 and the hydraulic rod 13 are fixedly connected. When in use, the hydraulic oil is introduced into the two oil inlet joints 12 to control the hydraulic rod 13 to perform telescopic activities in the cylinder body 11. This is the prior art. Furthermore, the hydraulic rod 13 is penetrated by a connecting groove 14, and the connecting groove 14 coincides with the axis of the hydraulic rod 13. The upper end of the connecting groove 14 is connected to the inside of the chamber Ⅰ, and the lower end of the connecting groove 14 is connected to the oil inlet pipe 333, and a solenoid valve 15 is provided between the connecting groove 14 and the oil inlet pipe 333. When in use, the hydraulic oil enters the chamber Ⅰ to push the hydraulic rod 13 downward. The pressure plate 20 moves to press the filter cartridge cover 40 onto the filter cartridge 50, and then the solenoid valve 15 is energized, so that the hydraulic oil in chamber I enters the connecting groove 14, enters the oil inlet pipe 333 through the connecting groove 14, enters the movable groove 331 through the oil inlet pipe 333, and then pushes the riveting punch 32 to punch outward. It can be understood that after the filter cartridge cover 40 presses on the filter cartridge 50, the hydraulic rod 13 reaches the maximum stroke. At this time, the hydraulic oil continues to be introduced into chamber I, and the hydraulic oil will automatically flow into the connecting groove 14. When the stamping is completed, the hydraulic oil in chamber I is discharged, and hydraulic oil is introduced into chamber II, so that the hydraulic rod 13 moves upward.

[0028] In some embodiments, a clamp 60 for clamping the filter cartridge cover 40 is provided on the surface of the pressure plate 20 .

[0029] The clamp 60 includes a clamping plate 61 slidably arranged on the surface of the pressure plate 20, a motor 62 fixed on the surface of the pressure plate 20, and a screw 63 fixedly connected to the output shaft of the motor 62. The screw 63 is threadedly connected to the clamping plate 61. When in use, the filter cartridge cover 40 can be placed on the surface of the pressure plate 20. By connecting the external power supply of the motor 62, the screw 63 can be driven to rotate. When the screw 63 rotates, it drives the clamping plate 61 to move and clamp the filter cartridge cover 40.

[0030] Preferably, the contact surface between the clamping plate 61 and the filter cartridge cover 40 is a curved surface structure, so that the surface of the clamping plate 61 can make better contact with the surface of the filter cartridge cover 40.

[0031] The number of the riveting punches 32 and the clamping plates 61 is not less than two and their positions correspond to each other.

[0032] The inner surface of the clamping plate 61 is provided with a clearance groove 64 .

[0033] In some embodiments, a heating wire 70 is installed in the riveting punch 32. The purpose of providing the heating wire 70 is that when the material of the filter is plastic, the riveting punch 32 can be heated by the heating wire 70. In this way, the filter cartridge cover 40 and the filter cartridge 50 can be riveted together by hot melting.

[0034] The working process of the pressing device for processing hydraulic oil filter cartridge of the utility model is as follows:

[0035] 1. Place the filter cartridge cover 40 to be pressed onto the pressure plate 20 and secure it with the clamp 60.

[0036] 2. The hydraulic rod 13 is extended by the hydraulic oil, and the hydraulic rod 13 drives the pressure plate 20 to descend when extended, so that the filter cartridge cover 40 is pressed onto the outer side of the upper end of the filter cartridge 50.

[0037] 3. Open the solenoid valve 15, the hydraulic oil flows from chamber I through the connecting groove 14, and enters the movable groove 331 through the connecting groove 14, driving the riveting punch 32 to punch outwards to form a riveted connection between the inner wall of the filter cartridge 50 and the inner wall of the filter cartridge cover 40. When the filter to be pressed is made of plastic, it is necessary to connect the external power supply of the heating wire 70 inside the riveting punch 32 before opening the solenoid valve 15, and heat the riveting punch 32 through the heating wire 70. In this way, when the riveting punch 32 punches outwards, the filter cartridge cover 40 and the filter cartridge 50 can be riveted together by hot melting.

[0038] 4. Release the fixture 60, introduce hydraulic oil into chamber II, reset the riveting punch 32, and raise the hydraulic rod 13 to complete a pressing cycle.

[0039] This new pressing method not only improves the working efficiency, but also effectively prevents the filter cartridge cover 40 from falling off, thereby ensuring the quality of the product.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
