Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder processing equipment, and in particular to a surface polishing device for hydraulic cylinder processing. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. This invention focuses on the machining of the piston rod. The piston rod is the connecting component that supports the piston in performing work. The piston rod has high machining requirements, with a surface roughness requirement of Ra0.4~0.8μm and strict requirements for coaxiality and wear resistance. Therefore, the piston rod needs to be polished.

[0003] The existing surface polishing device for machining hydraulic cylinder piston rods has a complex structure, is inconvenient to operate, and has a complicated operation process that results in low processing efficiency. Therefore, it is necessary to improve the existing surface polishing device for machining hydraulic cylinder piston rods. Utility Model Content

Detailed Implementation

[0021] like Figure 1-4 As shown, a surface polishing device for machining hydraulic cylinders includes an equipment box 1 and a receiving table 2 and a feeding table 3 disposed on both sides of the equipment box 1.

[0022] Two symmetrically arranged first motors 4 are connected to the top surface of the equipment box 1 via a sliding assembly. A polishing wheel 5 is connected to the output shaft of the first motor 4. A protective cover 15 is provided on the outer side of the polishing wheel 5 and the protective cover 15 is fixed to the first motor 4.

[0023] The sliding assembly includes a base 16 fixed to the top surface of the equipment housing 1 and a slide 17 disposed above the base 16. A slider 18 is connected to the bottom of the slide 17, and the slider 18 is slidably connected to a slide rail 19 disposed on the base 16. A bearing seat is connected to the top surface of the base 16, and a second lead screw 20 is rotatably connected to the bearing seat. A threaded sleeve is threaded onto the shaft of the second lead screw 20, and the threaded sleeve is fixed to the bottom surface of the slide 17. A second handwheel 21 is connected to the other end of the second lead screw 20. By rotating the second handwheel 21, the two slides 17 drive the two first motors 4 to move closer or further apart, thereby adjusting the distance between the two polishing wheels 5.

[0024] The top surface of the equipment box 1 is provided with pressing components at both ends. The pressing components include a U-shaped frame 6 that is upside down connected to the top surface of the equipment box 1. A first V-shaped wheel 7 is rotatably connected inside the U-shaped frame 6. The first V-shaped wheel 7 is driven by a second motor 8 connected to one side of the U-shaped frame 6. A second V-shaped wheel 9 is provided above the first V-shaped wheel 7. The second V-shaped wheel 9 is rotatably connected to a lifting frame 10. The two ends of the lifting frame 10 are slidably connected to the sliding grooves opened on the U-shaped frame 6. A first lead screw 11 is rotatably connected to the top of the lifting frame 10. The top end of the first lead screw 11 is threaded through the U-shaped frame 6 and connected to a first handwheel 12.

[0025] The feeding platform 3 is equipped with a pushing assembly, which includes a pushing box 22 and a hydraulic cylinder 23 connected to the pushing box 22. The piston end of the hydraulic cylinder 23 passes through a through hole in the pushing box 22 and is connected to a pushing plate 24. The pushing box 22 is provided with a first guiding inclined plate 25 and a second guiding inclined plate 26 connected to each other. The second guiding inclined plate 26 and the pushing box 22 form a guiding channel. The pushing box 22 is provided with a through hole at the position corresponding to the middle groove of the first V-shaped wheel 7. The piston rod, fed into the pusher box 22, falls into the guide channel via the first guide ramp 25 and the second guide ramp 26.

The piston rod is limited by the channel formed between the first V-shaped wheel 7 and the second V-shaped wheel 9. The piston rod is then pushed forward and polished by the two polishing wheels 5. After polishing, the piston rod is pushed forward again, so that the end of the piston rod away from the push plate 24 is placed between the two first V-shaped wheels 7 and the second V-shaped wheel 9 on the other side. The piston rod is pushed forward again until it falls onto the receiving table 2. Then, the hydraulic cylinder 23 drives the push plate 24 to reset and then the next piston rod is placed in the guide channel.

[0026] The bottom of the equipment box 1, the receiving platform 2 and the feeding platform 3 are all connected to adjustable support feet 13. The bottom of the equipment box 1 is connected to universal wheels 14 with brakes. The height of the adjustable support feet 13 at the bottom of the equipment box 1 can be adjusted to control whether the universal wheels 14 touch the ground.

[0027] Several sets of material support components are provided between the two polishing wheels 5. The material support components include two upright plates fixed on the top surface of the equipment box 1. Two symmetrically arranged auxiliary rollers are rotatably connected between the two upright plates. The material support components can support the piston rod being polished.

[0028] The operation process of this utility model is as follows:

[0029] In use, the piston rod is placed in the guide channel, and then the hydraulic cylinder 23 pushes the piston rod to move through the push plate 24, so that the end of the piston rod passes through the through hole on the push box 22 and is placed between the first V-shaped wheel 7 and the second V-shaped wheel 9. The piston rod is limited by the channel formed between the first V-shaped wheel 7 and the second V-shaped wheel 9. Then the piston rod continues to be pushed forward and polished by the two polishing wheels 5. After polishing, it continues to be pushed so that the end of the piston rod away from the push plate 24 is placed between the two first V-shaped wheels 7 and the second V-shaped wheel 9 on the other side. It continues to be pushed until the piston rod falls on the receiving table 2. Then the hydraulic cylinder 23 drives the push plate 24 to reset, and then the next piston rod is placed in the guide channel.
