Please note that, to clearly demonstrate the structure of the components in the embodiments of this utility model, the figures are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0022] Example 1: A grinding device for machining mechanical parts includes a support 1, a material platform 2 on the support 1, and a side frame 3 fixed on one side of the support 1. A grinding motor 4 for grinding drive is provided on the side frame 3, and a grinding disc 5 for grinding mechanical parts is fixed to the output shaft of the grinding motor 4. A shifting component for shifting the mechanical parts on the material platform 2 is provided in the middle of the side frame 3. The shifting component includes a T-shaped rotating groove 6 annularly opened on the top of the support 1, and a T-shaped rotating frame 7 fixed to the material platform 2 rotates annularly in the T-shaped rotating groove 6. A tooth 8 is fixed on the outer circumference of the material platform 2, and a stepper motor 9 for shifting drive of the shifting component is embedded in the middle of the side frame 3. A drive gear 10 that meshes with the tooth 8 is fixed to the output shaft of the stepper motor 9.
[0023] Specifically, this utility model, by setting up a repositioning component, firstly, the T-shaped rotating groove 6 and the T-shaped rotating frame 7 provide rotational support between the material platform 2 and the support 1. Then, by activating the stepper motor 9, the drive gear 10 is driven to rotate linearly. The linearly rotating drive gear 10 drives the material platform 2 to rotate linearly on the support 1 through the convex teeth 8. Subsequently, it performs a repositioning operation on several mechanical parts on the material platform 2, satisfying the repositioning and grinding requirements of several mechanical parts by the grinding disc 5 on the grinding motor 4. This replaces frequent manual intervention. Based on linear repositioning, it achieves a highly efficient grinding effect on multiple mechanical parts, with high efficiency, meeting the grinding needs of large batches of mechanical parts, and reducing manual labor intensity, saving time and effort.
[0024] The material platform 2 has a circumferential groove 11 for placing mechanical parts, and a permanent magnet 12 for electromagnetic positioning of the mechanical parts is embedded in the groove 11.
[0025] Specifically, this utility model uses a material trough 11 and a permanent magnet 12 to perform preliminary electromagnetic positioning on several mechanical parts placed on the material platform 2, thereby achieving the preliminary positioning effect of several mechanical parts to prevent displacement.
[0026] An electric suction nozzle 13 for adsorbing and positioning mechanical parts is fixed on the bottom circumference of the material platform 2, and the negative pressure nozzle of the electric suction nozzle 13 penetrates through the material groove 11 of the material platform 2 to the middle of the permanent magnet 12.
[0027] Specifically, this utility model uses an electric suction nozzle 13 to re-adsorb and position several mechanical parts, ensuring that the initially positioned mechanical parts are firmly adsorbed to prevent shaking or displacement during polishing and to improve the polishing quality of the mechanical parts.
[0028] The top of the side frame 3 is fixed with a lifting cylinder 14 for adjusting the height of the grinding disc 5 on the grinding motor 4.
[0029] Specifically, this utility model uses a lifting cylinder 14 to adjust the height and stroke of the grinding disc 5 on the grinding motor 4, so as to meet the grinding needs of the grinding motor 4 driving the grinding disc 5 to grind mechanical parts of different heights. It also ensures that the grinding disc 5 accurately reaches the grinding surface of the mechanical parts, so as to prevent the grinding from being too light and not meeting the roughness requirements, or from being over-grinded and causing damage to the mechanical parts.
[0030] A pusher cylinder 15 is horizontally placed on one side of the top of the support 1, and a pusher head 16 for pushing mechanical parts is fixed to the piston rod of the pusher cylinder 15. The head of the pusher head 16 is made of flexible silicone. A material box 17 for temporarily storing mechanical parts after pushing is fixed on the other side of the support 1, and a protective pad is wrapped inside the material box 17.
[0031] Specifically, this utility model uses a pusher cylinder 15 and a pusher head 16 to push and unload the polished mechanical parts. Before this, the electric suction nozzle 13 at the bottom of the polished mechanical parts in the material trough 11 needs to be closed to release its main positioning measures. A flexible silicone design is used to prevent the pusher head 16 from causing damage to the polished mechanical parts. A material box 17 is set up to temporarily place the pushed mechanical parts. The mechanical parts pushed into the material box 17 are picked up one by one to prevent collisions between materials. A protective pad is used to provide flexible buffering for the mechanical parts pushed into the material box 17 to prevent them from bumping into the polishing surface and affecting the polishing quality.
[0032] The material platform 2 is fixed with rim rings 18 that slide with the side frame 3 on both the upper and lower sides near the tooth 8. A dust pump 19 is fixed on the other side of the top of the support 1. The dust suction port of the dust pump 19 is connected to a dust suction hood 20 for adsorbing dust in the grinding area of the grinding disc 5 and mechanical parts. The dust discharge port of the dust pump 19 is connected to a dust discharge pipe 21. A dust storage chamber 22 is opened in the support 1 and is connected to the dust discharge pipe 21. A cleaning port is opened on the support 1 and is connected to the dust storage chamber 22. A cover is snapped onto the cleaning port.
[0033] Specifically, this utility model protects the protruding teeth 8 by setting the edge ring 18, and also ensures the stable rotation of the material platform 2 on the side frame 3, thereby improving the rotational stability of the material platform 2. This utility model also adsorbs the dust generated by the grinding disc 5 and the grinding area of mechanical parts by setting the dust pump 19 and the dust hood 20, thereby improving the cleanliness of the processing environment of the grinding disc 5 and the grinding area of mechanical parts, which is also conducive to the health of workers. By setting the dust discharge pipe 21 and the dust storage chamber 22, the adsorbed dust is discharged and stored, and the dust temporarily stored in the dust storage chamber 22 is periodically cleaned by opening the cover.
[0034] The specific usage process is as follows: First, several groups of mechanical parts to be polished are placed in the material troughs 11 on the material platform 2. Then, several groups of permanent magnets 12 electromagnetically attract the bottom of the mechanical parts. Next, several groups of electric suction nozzles 13 apply negative pressure to the electromagnetically attracted mechanical parts to achieve secondary positioning. After the positioning of several groups of mechanical parts to be polished is completed, the lifting cylinder 14 is controlled to drive the polishing disc 5 on the polishing motor 4 to move down to the polishing surface of the first group of mechanical parts. Then, the polishing motor 4 is controlled to drive the polishing disc 5 to polish the polishing surface of the first group of mechanical parts. After the polishing surface of the first group of mechanical parts is finished, the polishing disc 5 moves up to reset. Then, the stepper motor 9 is controlled to start and drive the drive gear 10 to rotate linearly. The T-shaped rotating groove 6 and the T-shaped... With the rotating frame 7 providing rotational support for the material platform 2 and the support 1, the linearly rotating drive gear 10 drives the material platform 2 to rotate via the convex tooth 8. The linearly rotating material platform 2 rotates and positions the grinding surface of the second group of mechanical parts directly below the grinding disc 5. Then, the grinding disc 5 is controlled to move down to grind the grinding surface of the second group of mechanical parts. This process is repeated until all grinding surfaces of several groups of mechanical parts have been ground. During this period, when the mechanical parts that have completed grinding on the material trough 11 rotate to the front of the pusher head 16, the electric suction nozzle 13 at the corresponding material trough 11 is first controlled to close, and then the pusher cylinder 15 is controlled to open and push the mechanical parts that have rotated into position and completed grinding into the material box 17 through the pusher head 16. This process is repeated until all grinding surfaces of the mechanical parts have been ground. Several sets of mechanical parts for grinding are pushed and unloaded one by one. At the same time, the dust pump 19 is turned on and the dust suction hood 20 applies negative pressure to adsorb the dust generated during the grinding of the grinding disc 5 and several sets of mechanical parts. Then, the dust adsorbed is discharged into the dust storage chamber 22 in the support 1 through the dust discharge pipe 21 for temporary storage. The cover is opened periodically to remove the dust in the dust storage chamber 22. This utility model sets up a displacement component. First, the T-shaped rotating groove 6 and the T-shaped rotating frame 7 provide rotational support between the material platform 2 and the support 1. Then, the stepper motor 9 drives the drive gear 10 to rotate linearly. The linearly rotating drive gear 10 drives the material platform 2 to rotate linearly on the support 1 through the convex teeth 8, thereby displacing several mechanical parts on the material platform 2. The operation satisfies the grinding disc 5 on the grinding motor 4 to perform repositioning and grinding of several mechanical parts, replacing frequent manual intervention. Based on linear repositioning, it achieves efficient grinding of multiple mechanical parts, with high efficiency, meeting the grinding needs of large batches of mechanical parts, and reducing manual labor intensity, saving time and effort. This utility model uses a material trough 11 and a permanent magnet 12 to perform preliminary electromagnetic positioning of several mechanical parts placed on the material platform 2, achieving a preliminary positioning effect to prevent displacement. This utility model uses an electric suction nozzle 13 to perform secondary adsorption and positioning of several mechanical parts, so that the mechanical parts after preliminary positioning are firmly adsorbed to prevent shaking and displacement during grinding, thereby improving the grinding quality of mechanical parts.This invention uses a lifting cylinder 14 to adjust the height and stroke of the grinding disc 5 on the grinding motor 4, meeting the grinding needs of the grinding motor 4 driving the grinding disc 5 to grind mechanical parts of different heights. This also ensures the grinding disc 5 accurately reaches the grinding surface of the mechanical parts, preventing under-grinding that fails to meet roughness requirements or over-grinding that damages the mechanical parts. The invention also uses a pushing cylinder 15 and a pushing head 16 to push the ground mechanical parts out of the machine. Before this, the electric suction nozzle 13 at the bottom of the ground mechanical parts in the material trough 11 must be closed to release its main positioning mechanism. A flexible silicone design is used to prevent the pushing head 16 from damaging the ground mechanical parts. A material box 17 is used to temporarily hold the pushed-out mechanical parts. The mechanical parts pushed into the material box 17 are removed one by one to prevent collisions between materials. Protective pads provide flexible cushioning to prevent impacts on the grinding surface and affecting grinding quality. The invention also features an edge ring 18 to protect the protruding teeth 8 and ensure stable rotation of the material platform 2 on the side frame 3, improving the rotational stability of the material platform 2. Furthermore, a dust pump 19 and a dust hood 20 are used to absorb dust generated in the grinding area of the grinding disc 5 and the mechanical parts grinding area, improving the cleanliness of the processing environment and contributing to worker health. A dust discharge pipe 21 and a dust storage chamber 22 are used to discharge and store the absorbed dust, and the dust temporarily stored in the dust storage chamber 22 is periodically cleaned by opening the cover.
[0035] In summary, this grinding device for machining mechanical parts, by setting up a shifting component, firstly, the T-shaped rotating groove and T-shaped rotating frame provide rotational support between the material table and the support, and then the stepper motor drives the drive gear to rotate linearly. The linearly rotating drive gear drives the material table to rotate linearly on the support through the convex teeth, thereby performing a shifting operation on several mechanical parts on the material table, satisfying the shifting and grinding requirements of several mechanical parts by the grinding disc on the grinding motor.
[0036] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
