This equipment has a high degree of automation, stable and reliable processing, and is suitable for mass production, which can significantly improve the performance and service life of hydraulic cylinders.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an automatic honing machine for hydraulic cylinder barrels, including a tank body 1, a slide rail 2, a sliding frame 3, and a drain pipe 4. The slide rail 2 is symmetrically and fixedly connected to the left side of the tank body 1, and the sliding frame 3 is slidably connected to the left side of the slide rail 2. An automatic honing mechanism is provided on the top of the sliding frame 3. The drain pipe 4 is connected to the right side of the tank body 1. A crossbeam 6 is fixedly connected to the top of the tank body 1, and a limiting mechanism is provided on the top of the crossbeam 6. A support mechanism is provided on one side of the crossbeam 6. The hydraulic cylinder barrel is connected to an externally rotatable three-jaw chuck, and the hydraulic cylinder barrel passes through... The limiting mechanism is connected to the three-jaw chuck and fits against the outer wall of the hydraulic cylinder barrel, which can limit its position and prevent excessive displacement of the hydraulic cylinder barrel during honing, thus affecting the honing effect. The three-jaw chuck drives the hydraulic cylinder barrel to rotate, and works with the automatic honing mechanism to automatically hone the inner wall of the hydraulic cylinder barrel. The support mechanism can be adjusted to provide segmented support for the hydraulic cylinder barrel and also works with the automatic honing mechanism to perform segmented honing, avoiding the problem of the hydraulic cylinder barrel being prone to bending or torsional deformation due to not changing according to the processing position of the hydraulic cylinder barrel.
[0019] The support mechanism includes a limiting frame 11, locking bolts 12, a support frame 13, an arc-shaped plate 14, and ball bearings 15. Limiting frames 11 are symmetrically arranged on both sides of the crossbeam 6, and locking bolts 12 are symmetrically fixedly connected to both sides of the crossbeam 6. The top of the locking bolt 12 penetrates the inner wall of the limiting frame 11 and is threaded with a nut. A support frame 13 is fixedly connected to one end of the limiting frame 11, and an arc-shaped plate 14 is fixedly connected between the two support frames 13. Ball bearings 15 are symmetrically rotatably connected to both ends of the arc-shaped plate 14. Loosening the nuts on the locking bolts 12 allows the limiting frame 11 to move linearly along the outer wall of the locking bolt 12. The arc plate 14 moves back and forth, and is connected to the limit frame 11 by the support frame 13 to drive the arc plate 14 to move. It moves at fixed distances according to the width of the arc plate 14. After each movement, the nut on the locking bolt 12 is tightened to lock the position, which is used to support the hydraulic cylinder barrel in sections. This avoids the problem that the hydraulic cylinder barrel is easy to bend or twist and deform if it does not change according to the processing position of the hydraulic cylinder barrel. The arc plate 14 supports the hydraulic cylinder barrel through the ball bearings 15. The ball bearings 15 can reduce the friction between the hydraulic cylinder barrel and the arc plate 14, making the movement of the hydraulic cylinder barrel smoother.
[0020] The limiting mechanism includes a fixed plate 7, a movable plate 8, a strip groove 9, and fastening bolts 10. A fixed plate 7 is fixedly connected to the top of the crossbeam 6. A movable plate 8 is located on the top of the fixed plate 7. Strip grooves 9 are symmetrically arranged on both sides of the movable plate 8. Fastening bolts 10 are symmetrically fixedly connected to both sides of the top of the fixed plate 7. One end of each fastening bolt 10 passes through the interior of the strip groove 9 and is threaded with a pressure cap. The top of the ball bearing 15 is in contact with the bottom of the hydraulic cylinder barrel. A V-shaped groove is provided between the movable plate 8 and the fixed plate 7. The two V-shaped grooves are respectively in contact with the top and bottom of the hydraulic cylinder barrel. One end of the hydraulic cylinder barrel extends from the fixed plate 7... After passing through the V-shaped groove between the fixed plate 7 and the movable plate 8, the V-shaped groove inside the fixed plate 7 fits against the bottom of the hydraulic cylinder barrel. Loosen the cap on the fastening bolt 10, and the movable plate 8 slides down, its internal V-shaped groove fitting against the top of the hydraulic cylinder barrel. Tighten the cap on the fastening bolt 10, and the cap clamps and locks the fixed plate 7 and the movable plate 8 in a fixed position to restrict the position of the hydraulic cylinder barrel. After the hydraulic cylinder barrel is honed, loosen the cap again to release the locking state of the fixed plate 7 and the movable plate 8. The three-jaw chuck releases one end of the hydraulic cylinder barrel, and the hydraulic cylinder barrel can be taken out of the automatic honing machine.
[0021] The automatic honing mechanism includes a honing roller 16, a lead screw 18, and a second motor 19. The lead screw 18 is rotatably connected to the left side of the pool body 1, and the second motor 19 is fixedly installed on the left side of the slide rail 2. The output end of the second motor 19 is fixedly connected to the left end of the lead screw 18, and the right end of the lead screw 18 passes through the interior of the sliding frame 3 and is threadedly connected to it. The honing roller 16 is fixedly installed on the top of the sliding frame 3. The second motor 19 can drive the lead screw 18 to rotate, and the slide rail 2 restricts the movement of the sliding frame 3. The moving trajectory, the lead screw 18 rotates forward and backward, which can drive the sliding frame 3 to move horizontally back and forth. The honing roller 16 is installed on the top of the sliding frame 3. The sliding frame 3 can drive the honing roller 16 to move back and forth. Adjusting the position of the honing roller 16, so that the sliding frame 3 drives the honing roller 16 to move back and forth at the position supported by the arc plate 14, is used to hone the hydraulic cylinder barrel in sections, so as to avoid the problem that the hydraulic cylinder barrel is easy to bend or twist and deform due to not changing according to the processing position of the hydraulic cylinder barrel.
[0022] The left side of the pool body 1 is symmetrically and fixedly connected with top rods 20. A rotating roller 21 is rotatably connected between the top ends of the two top rods 20. The right end of the honing roller 16 is in contact with the top of the rotating roller 21. The rotating roller 21 is supported by the cylinder of the hydraulic cylinder. The rotating roller 21 can rotate to reduce the friction between itself and the honing roller 16, so that the honing roller 16 moves more smoothly.
[0023] An inclined plate 5 is fixedly connected inside the pool body 1. Coolant is stored on the left side of the inclined plate 5. A pump body 22 is fixedly installed on the left side of the pool body 1. The input end of the pump body 22 is connected to the left side of the pool body 1. The output end of the pump body 22 is connected to a nozzle 24 through a metal hose. A protective cover 25 is fixedly connected to the top of the pool body 1. The pump body 22 and the delivery pipe 23 cooperate to deliver the coolant from the left side of the inclined plate 5 into the nozzle 24. The nozzle 24 sprays the coolant from left to right into the interior of the hydraulic cylinder barrel to automatically flush the hydraulic cylinder barrel and reduce its temperature. The flushing waste liquid flows to the right side of the inclined plate 5. When it is full, it is discharged outward through the drain pipe 4.
[0024] The automatic honing machine for hydraulic cylinder barrels loosens the nut on the locking bolt 12, allowing the limiting frame 11 to reciprocate linearly along the outer wall of the locking bolt 12. The arc plate 14 is connected to the limiting frame 11 via the support frame 13, which drives the arc plate 14 to move. The arc plate 14 moves at fixed intervals according to its width. After each movement, the nut on the locking bolt 12 is tightened to lock the position, thus providing segmented support for the hydraulic cylinder barrel and preventing the hydraulic cylinder barrel from easily bending or twisting due to changes in the processing position. After one end of the hydraulic cylinder barrel passes through the V-shaped groove between the fixed plate 7 and the movable plate 8, the V-shaped groove inside the fixed plate 7 fits against the bottom of the hydraulic cylinder barrel. The pressure cap on the fastening bolt 10 is loosened, and the movable plate 8 slides down, its internal V-shaped groove fitting against the top of the hydraulic cylinder barrel. The pressure cap on the fastening bolt 10 is tightened, clamping the fixed plate 7 and the movable plate 8 to lock the position, thus limiting the position of the hydraulic cylinder barrel.
