Specific embodiments
[0023] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0024] As Figures 1-7 Shown is a highly protective AGC oil cylinder dust-proof sealing structure, which includes an oil cylinder body 1 and a connecting bolt 2. An anti-collision structure 3 is provided on the oil cylinder body 1. The anti-collision structure 3 includes a plurality of shock absorbers 4 fixedly installed on the oil cylinder body 1. One end of the shock absorber 4 is fixedly installed with adjacent first protective plates 5 and second protective plates 6. A connecting column 7 is fixedly installed at the interval between the first protective plate 5 and the second protective plate 6. The front baffle 8 and the rear baffle 9 connected to the connecting column 7 are respectively installed at the front and rear ends of the oil cylinder body 1. Through the setting of the anti-collision structure 3, on the basis of the good dust-proof sealing performance of the oil cylinder body 1, it has an anti-collision effect, avoiding the risk of collision in the working environment of the AGC oil cylinder due to the movement, vibration of mechanical components or personnel operation; after a plurality of shock absorbers 4 are installed on the side of the oil cylinder body 1, one end of the shock absorber 4 is respectively installed with the first protective plate 5 and the second protective plate 6. When the impact force acts on the first protective plate 5 and the second protective plate 6, the plurality of shock absorbers 4 can slow down the impact force, so that the vibration of the impact will not be transmitted to the oil cylinder body 1; the design of the plurality of first protective plates 5 and second protective plates 6 not only avoids the oil cylinder body 1 from being collided, but also prevents personnel from being injured when touching the machine during operation; the front baffle 8 and the rear baffle 9 can play a role in closing the two ends of the oil cylinder body 1, avoiding dust or other sundries from entering and adhering to the oil cylinder body 1, resulting in its failure; the design of the anti-collision structure 3 enables the precision parts inside the oil cylinder body 1 not to loosen due to collision, and can reduce the probability of the oil cylinder body 1 being damaged by collision.
[0025] As Figure 3As shown in the figure, a plurality of sliding grooves 10 are formed in the connecting column 7. Inside the sliding grooves 10, sliding blocks 11 connected to the first protective plate 5 and the second protective plate 6 are movably installed. The arrangement of the sliding grooves 10 and the sliding blocks 11 can reduce the friction between the first protective plate 5 and the second protective plate 6, reduce the wear of both, and increase the service life of the first protective plate 5 and the second protective plate 6.
[0026] As Figure 2 shown in the figure, a limiting hole 12 is formed at one end of the connecting column 7. On one side of the rear baffle 9, a plurality of limiting rods 13 adapted to the limiting hole 12 are fixedly installed. After aligning the plurality of limiting rods 13 and inserting them into the limiting hole 12, the rear baffle 9 can be fixed on the connecting column 7 to prevent it from falling off. Pulling the rear baffle 9 can also disassemble it, so as to facilitate the maintenance of the oil cylinder body 1 without the need to disassemble the entire anti-collision structure 3.
[0027] As Figure 4 and Figure 5 shown in the figure, a nut 14 is fixedly installed at one end of the oil cylinder body 1. A threaded hole 15 is formed in the rear baffle 9. A screw rod 16 connected to the nut 14 is movably installed on the rear baffle 9. After the rear baffle 9 is fixed on the connecting column 7, inserting the screw rod 16 into the threaded hole 15 and tightening it until it is fastened to the nut 14 can further improve the stability of the rear baffle 9.
[0028] As Figure 5 shown in the figure, a plurality of insertion rods 17 are fixedly installed at one end of the screw rod 16. The arrangement of the insertion rods 17 can increase the force-bearing area at one end of the screw rod 16, so that the hand is not easily slipped when the operator rotates the screw rod 16, facilitating the disassembly and installation of the screw rod 16.
[0029] As Figure 6 shown in the figure, a plurality of fixing plates 18 are fixedly installed on the front baffle 8. An electric telescopic rod 19 is fixedly installed on one side of the fixing plate 18. A clamping block 20 is installed at the output end of the electric telescopic rod 19. After the oil cylinder body 1 is connected to the mechanical transmission part and fixed by the connecting bolt 2, then start the operation of the plurality of electric telescopic rods 19 to drive the clamping block 20 to approach and clamp the connecting bolt 2, so as to fix the connecting bolt 2 and prevent the connecting bolt 2 from loosening due to vibration.
[0030] As Figure 7As shown, a fixed block 21 is fixedly installed on the electric telescopic rod 19. A plurality of mounting holes 22 are formed in the fixed block 21. A spring 23 is fixedly installed inside the mounting hole 22. One end of the spring 23 is fixedly installed with a clamping ball 24. A plurality of clamping holes 25 for cooperating with the clamping ball 24 are formed inside the clamping block 20. The clamping ball 24 is clamped in the clamping hole 25 under the elastic action of the spring 23 to fix the clamping block 20 and prevent it from falling off. Pull the clamping block 20 so that the clamping ball 24 is squeezed and contracted into the inside of the mounting hole 22. When the clamping ball 24 disengages from the inside of the clamping hole 25, the clamping block 20 can be disassembled, thus facilitating the disassembly and replacement of the clamping block 20.
[0031] The working process of the highly protective AGC oil cylinder dust-proof sealing structure provided in this embodiment is as follows:
[0032] After a plurality of shock absorbers 4 are installed on the side of the oil cylinder body 1, a first protective plate 5 and a second protective plate 6 are respectively installed at one end of the shock absorbers 4. When an impact force acts on the first protective plate 5 and the second protective plate 6, the plurality of shock absorbers 4 can slow down the impact force, so that the impact vibration will not be transmitted to the oil cylinder body 1. The design of the plurality of first protective plates 5 and second protective plates 6 not only prevents the oil cylinder body 1 from being collided, but also prevents personnel from being injured when operating the machine. The front baffle 8 and the rear baffle 9 can seal the two ends of the oil cylinder body 1 to prevent dust or other sundries from entering and adhering to the oil cylinder body 1. The design of the anti-collision structure 3 makes the precision parts inside the oil cylinder body 1 not loosen due to collision, reducing the probability of the oil cylinder body 1 being damaged by collision.
[0033] It should be understood that the present invention is not limited to the form disclosed herein. Modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
