Description

Technical Field

[0001] This utility model relates to the field of shock absorber inner cylinder processing technology, specifically a deburring and cutting device for processing automotive shock absorber inner cylinders. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of the spring after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride smoothness of the car. When driving over uneven roads, although the shock-absorbing spring can filter out the vibrations from the road surface, the spring itself will still have reciprocating motion. Shock absorbers are used to suppress this spring bounce.

[0003] The inner cylinder is a component of an automotive shock absorber. Internally, it contains a piston, piston rod, and valve structure. The piston moves up and down within the inner cylinder, compressing the oil (shock absorber oil) through precisely designed valves, thereby generating damping force to absorb and dissipate vibration energy. During the machining of the inner cylinder, it requires cutting, leaving small burrs at both ends. Typically, the cut inner cylinder is transferred to a grinding machine for further processing. The clamping mechanism on the grinding machine is then used to clamp and secure the inner cylinder, making the process cumbersome, time-consuming, and labor-intensive, thus affecting the machining efficiency of the inner cylinder. Utility Model Content

[0004] The purpose of this utility model is to provide a deburring and cutting device for processing the inner cylinder of an automotive shock absorber. The cutting disc simultaneously cuts both ends of the inner cylinder, which is more efficient than single-sided cutting and also facilitates deburring of the cut end face. It is simple and convenient to operate and improves the processing efficiency of the inner cylinder, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deburring and cutting device for processing the inner cylinder of an automotive shock absorber, comprising a cutting table and a clamping mechanism connected to the top of the cutting table. The cutting table is connected to two support plates and a fixed seat. The support plates are connected to a grinding mechanism for deburring both ends of the inner cylinder.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a deburring and cutting device for processing the inner cylinder of an automotive shock absorber, including a cutting table 1 and a clamping mechanism connected to the top of the cutting table 1. The cutting table 1 is connected to two support plates 5 and a fixed seat 10. The support plates 5 are connected to a grinding mechanism for deburring both ends of the inner cylinder. The fixed seat 10 is connected to a cutting mechanism for cutting the inner cylinder. The cutting mechanism includes a U-shaped plate 9, two connecting plates 8, two cutting motors 7, and two cutting discs 6. The two ends of the connecting plates 8 are connected to the grinding mechanism and the U-shaped plate 9. The cutting motors 7 are fixed to the U-shaped plate 9, and the power output end of the cutting motors 7 is connected to the cutting discs 6. The U-shaped plate 9 is connected to a cylinder 11 for driving the U-shaped plate 9 to reciprocate.

[0021] When the inner cylinder is placed on the two support seats 2, the cylinder 11 drives the U-shaped plate 9 to move backward. The U-shaped plate 9 applies a pulling force to the two connecting plates 8 simultaneously. The connecting plates 8 pull the fixed frame 13, the grinding motor 3, and the grinding disc 4 to move forward. At this time, the grinding motor 3 is in the stopped state, and the two grinding discs 4 are pressed against the two ends of the inner cylinder, which facilitates the adjustment of the inner cylinder position, so that the inner cylinder is in a suitable processing position, which is convenient for subsequent cutting operations. There is no need for manual operation of the inner cylinder, and the adjustment accuracy is high.

[0022] The clamping mechanism includes two support seats 2, two adjusting bolts 18, two clamping grooves 19, two clamping plates 20, and two guide posts 21. The two support seats 2 are connected to the top of the cutting table 1. The clamping grooves 19 are located on the top of the support seats 2 and the bottom of the clamping plates 20. The guide posts 21 guide the clamping plates 20. The adjusting bolts 18 drive the clamping plates 20 to rise and fall. After the inner cylinder position is adjusted, rotating the adjusting bolts 18 drives the clamping plates 20 to move downward, so that the clamping grooves 19 press against the inner cylinder, thereby locking and fixing the inner cylinder, improving the stability of the inner cylinder, and facilitating subsequent cutting and deburring operations.

[0023] The top of the support base 2 is provided with a V-shaped groove 22. The inner surfaces of the V-shaped groove 22 and the pressing groove 19 are made of rubber, which can not only prevent the inner cylinder from being worn when it comes into contact with the V-shaped groove 22 and the pressing groove 19, but also increase the contact friction and prevent the inner cylinder from slipping when it is pressed.

[0024] One end of the guide post 21 is fixed to the pressure plate 20, and the other end is inserted into the support base 2 and slidably connected. The guide post 21 guides the pressure plate 20 and improves the stability of the pressure plate 20 in raising and lowering.

[0025] The adjusting bolt 18 is rotatably connected to the clamping plate 20, and the adjusting bolt 18 is threadedly connected to the support base 2.

[0026] The grinding mechanism includes two grinding motors 3, two grinding discs 4, two fixed frames 13, two moving columns 14, two springs 15, two guide cylinders 16, and multiple guide columns 17. The guide columns 17 and moving columns 14 are used to guide the grinding discs 4 and grinding motors 3. The fixed frames 13 are fixedly connected to the grinding motors 3. The power output end of the grinding motors 3 is connected to the grinding discs 4. The two ends of the connecting plate 8 are axially connected to the fixed frames 13 and the U-shaped plate 9. The end of the guide cylinder 16 is fixedly connected to the support plate 5. The springs 15 are sleeved on the moving columns 14, and the two ends of the springs 15 are connected to the fixed frames 13 and the guide cylinders 16.

[0027] When the inner cylinder is in the positioning state, the cylinder 11 drives the U-shaped plate 9 to move forward, which in turn drives the cutting motor 7 and the cutting disc 6 to move forward. The cutting motor 7 drives the cutting disc 6 to rotate, which facilitates the cutting operation of the inner cylinder. During the forward movement of the U-shaped plate 9, a pushing force is applied to the two connecting plates 8, so that the two grinding discs 4 are in a state of mutual distance, avoiding contact with the inner cylinder.

[0028] After the inner cylinder is cut, the cylinder 11 drives the U-shaped plate 9 to move backward, the cutting disc 6 separates from the inner cylinder, the U-shaped plate 9 drives the two connecting plates 8 to apply tension synchronously, the connecting plates 8 pull the grinding motor 3, the grinding disc 4 and the fixed frame 13 to move forward synchronously, that is, the two grinding discs 4 move closer to each other, the grinding motor 3 drives the grinding disc 4 to rotate, which facilitates the grinding and deburring of the cut end.

[0029] One end of the movable column 14 is fixedly connected to the fixed frame 13, and the other end is inserted into the guide cylinder 16 and slidably connected. The second guide column 17 is slidably connected to the support plate 5, and the end of the second guide column 17 is fixedly connected to the fixed frame 13. When the fixed frame 13 moves, it synchronously drives the movable column 14 and the second guide column 17 to move, which plays a good guiding role for the fixed frame 13 and improves the stability of the movement of the fixed frame 13, the grinding motor 3, and the grinding disc 4.

[0030] The fixed base 10 is slidably connected with multiple guide posts 12. The ends of the guide posts 12 are connected to the U-shaped plate 9. The guide posts 12 guide the U-shaped plate 9, improve the stability of the movement of the cutting motor 7 and the cutting disc 6, and can accurately cut the inner cylinder.

[0031] Cylinder 11 is fixed to the fixed base 10, and the power output end of cylinder 11 is connected to U-shaped plate 9.

[0032] Working principle: The inner cylinder is placed on top of the two support bases 2 and connected to the V-shaped groove 22. The operating cylinder 11 drives the U-shaped plate 9 to move backward, and with the use of the two connecting plates 8, the two grinding discs 4 are brought closer together, pressing the grinding discs 4 against both ends of the inner cylinder, facilitating the adjustment of the inner cylinder's position to a suitable processing position. After the inner cylinder is adjusted, rotating the adjusting bolt 18 drives the clamping plate 20 to move downward, causing the clamping groove 19 to press against the inner cylinder, achieving locking and fixing of the inner cylinder and improving its stability. Subsequently, the cylinder 11 drives the U-shaped plate 9 to move forward, synchronously driving the two cutting motors 7 and the two cutting discs 6 to move forward. The cutting motors 7 drive the cutting discs 6 to rotate, facilitating simultaneous cutting of both ends of the inner cylinder and improving cutting efficiency. After cutting is completed, cylinder 11 drives U-shaped plate 9 to move backward, separating cutting disc 6 from inner cylinder. U-shaped plate 9 applies tension to two connecting plates 8, and connecting plates 8 pull fixed frame 13, grinding motor 3, and grinding disc 4 forward. Grinding motor 3 drives grinding disc 4 to rotate, which facilitates grinding and deburring of the cutting end, improves the processing efficiency of inner cylinder, and is highly practical.
