Description

Technical Field

[0001] The utility model relates to the technical field of cotter pin production, in particular to a double-end surface grinding cotter pin device. Background Art

[0002] A cotter pin is a metal hardware part, commonly known as a spring pin. It is a mechanical part used to prevent threaded connections from loosening. After the nut is tightened, the cotter pin is inserted into the nut slot and the hole at the end of the bolt, and the tail of the cotter pin is pulled apart to prevent the nut and bolt from rotating relative to each other. High-quality steel and rigid materials with good elasticity are required to make this part.

[0003] Existing Chinese patent document CN202221637315.3 discloses a cotter pin processing device for high-voltage line porcelain bottles, including a mounting frame, a fixing device for fixing a steel cap, and an angle-dividing device for opening the tail of the cotter pin; the mounting frame includes a mounting base, a mounting rod installed on the mounting base, and a mounting upper plate installed on the mounting rod; the fixing device is installed on the mounting base; the angle-dividing device includes a mechanical arm suspended on the mounting upper plate and an angle-dividing steel sheet installed on the mechanical arm, and the angle-dividing device is located above the fixing device. When the tail of the cotter pin for the high-voltage line porcelain bottle needs to be separated, the steel cap with the cotter pin placed on it is placed on the fixing device, and the end with the opening at the top of the mounting groove is placed upwards, and then the mechanical arm located above the fixing device and suspended on the mounting upper plate moves downward, so that the angle-dividing steel sheet installed on the mechanical arm is pressed against the tail of the cotter pin, thereby separating the tail of the cotter pin, which is beneficial to saving manpower.

[0004] However, the above patent has certain defects when used. Since the tail of the split pin needs to be broken apart during use, and the device does not have a process for grinding the burrs on the end surface during the production of the split pin, burrs are likely to remain, which makes it inconvenient during subsequent use.

[0005] For this reason, a double-end surface ground cotter pin device is proposed to solve the above-mentioned problems. Utility Model Content

[0025] A fixing plate 62 is provided on the front of the top plate 6, and the fixing plate 62 is fixedly connected to the top plate 6. The fixing plate 62 provides an installation base for the electric hydraulic telescopic cylinder 7. The upper surface of the fixing plate 62 is provided with an electric hydraulic telescopic cylinder 7, and the output end of the electric hydraulic telescopic cylinder 7 is provided with a telescopic rod, and the end of the telescopic rod is provided with a mounting plate 5. A bending die 8 is provided at the bottom of the mounting plate 5, and a die cavity 81 is provided inside the bending die 8. The bending die 8 is used to bend the cotter pin; by providing the die cavity 81 inside the bending die 8, when the electric hydraulic telescopic cylinder 7 pushes the mounting plate 5 to move downward, the die cavity 81 of the bending die 8 contacts the cotter pin raw material 9 and applies pressure, causing it to undergo plastic deformation to form the required bending angle.

[0026] A bending column 21 is provided on the front of the processing table 2, and the bending column 21 is arranged directly below the bending die 8 for supporting the cotter pin during the bending process. The bending column 21 provides a reaction force during the bending process to prevent the raw material from shifting or deforming during the bending process. A connecting block 22 is provided below the processing table 2, and a motor 31 is provided on the back of the connecting block 22. A rotating shaft 32 is provided at the output end of the motor 31, and the rotating shaft 32 passes through the connecting block 22 and extends to the front of the processing table 2. A cleaning brush 3 is provided on the rotating shaft 32, and the cleaning brush 3 is used to grind the two end faces of the bottom of the cotter pin to remove burrs.

The adjustment block 42 can move within the chute and is fixedly connected to the processing table 2 by bolts. When cotter pins of different sizes need to be produced, only the position of the conveying block 4 and the cutter 82 needs to be adjusted to accommodate cotter pin raw materials 9 of different lengths for cutting and bending, thereby improving the versatility and flexibility of the equipment.

[0031] The working principle of the present invention is as follows: when in use, the split pin raw material 9 is placed in the conveying block 4, the split pin raw material 9 is moved to the processing table 2 through the transmission groove on the conveying block 4, the adjusting block 42 is adjusted in the chute according to the length of the raw material, and is fixed by bolts to ensure that the raw material can be accurately in place;

[0032] The electric hydraulic telescopic cylinder 7 is activated, pushing the mounting plate 5 and the bending die 8 at the bottom downward, so that the die cavity 81 of the bending die 8 contacts the two ends of the split pin raw material 9. The cutter 82 on the right side of the mounting plate 5 is then activated to cut and separate the split pin to form a separate finished product. The electric hydraulic telescopic cylinder 7 continues to push the bending die 8, so that the split pin raw material 9 is bent in the die cavity 81 to form the required bending angle.

[0033] After the bending is completed, the mounting plate 5 does not move, the motor 31 is started, and the cleaning brush 3 driven by the motor 31 starts to work. The cleaning brush 3 starts to rotate and grinds the two end surfaces of the cotter pin to remove burrs and debris to ensure safety in subsequent use.
