Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and specifically relates to a feeding mechanism for a key grinding machine. Background Technology

[0002] Keys are a common unlocking tool in people's lives. The main materials for making keys are copper, zinc, aluminum, iron and other metals. The feeding mechanism of the key grinding machine is designed for ordinary door lock key grinding machines, and the front and back of the key blank are completely identical.

[0003] Traditional key grinding machine feeding mechanisms cannot guarantee consistent feeding direction, resulting in random orientation of the key grinding surfaces. This increases the workload of manual adjustment or secondary positioning, reducing production efficiency. At the same time, key blanks are prone to jamming due to accumulation or misalignment during feeding, affecting positioning accuracy. Multiple keys may be stacked vertically, causing channel blockage, frequent machine shutdowns for cleaning, and further reducing production efficiency.

[0004] To address the problems mentioned in the background above, a feeding mechanism for a key grinding machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a key grinding machine, which has the advantages of calibrating the orientation and preventing blockage.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a key grinding machine feeding mechanism includes a base, a motor is embedded in the middle of the top of the base, a turntable is fixedly sleeved on the top of the output end of the motor, the top of the turntable has an opening, the bottom of the turntable is provided with a fixed plate, the rear end of the right side of the top of the fixed plate has a calibration port, the front end of the right side of the top of the fixed plate has a channel, a hopper is bolted to the top of the right side of the base, a conveying pipe is bolted to the top of the hopper, a slot is opened through the center of the top of the fixed plate, and the surface of the output end of the motor penetrates the interior of the slot, and an anti-blocking mechanism is provided on the left side of the top of the conveying pipe.

[0007] The above technical solution involves placing a collection box at the bottom of the calibration port. Key blanks are placed into the inlet, enter the conveyor pipe, and then into the hopper. The key blanks are placed horizontally inside the hopper, with their orientation unknown. A motor drives a turntable to rotate, which in turn rotates the opening. When the opening reaches the bottom of the hopper, the key blank naturally slides into it. The opening then rotates the key blank, passing it through the calibration port. If the handle of the key blank faces the inside of the turntable, it matches the calibration port. Matched key blanks fall from the calibration port into the collection box at the bottom and are placed back into the opening for re-feeding. If the orientation does not match the calibration port, the key blank is rotated to the rightmost opening of the turntable and slides down the channel to the grinding machine. This consistent feeding direction significantly improves processing efficiency and accuracy, corrects key orientation, avoids adjustment errors and wasted time, ensures the grinding surface of each key aligns with the tool, reduces scrap rate, and simplifies subsequent sorting processes, reducing production costs. It is particularly suitable for mass production of standardized keys.

[0008] The present invention is further configured such that the anti-blocking mechanism includes a second motor, which is embedded in the left side of the top of the conveying pipe. A cam is fixedly sleeved on the top of the second motor, and a pulley is slidably connected to the right side of the cam surface. A spring is bolted to the right side of the pulley, and an inlet is bolted to the right side of the spring.

[0009] The above technical solution employs an anti-blocking mechanism. The key blank is poured into the inlet and then enters the delivery pipe. The bottom of the inlet and the inside of the delivery pipe are flattened, requiring the key blank to slide vertically against the wall into the delivery pipe. Motor two drives a cam to rotate, which in turn drives a pulley. During rotation, the raised part of the cam compresses and moves the pulley. As the pulley moves, a spring contracts. When the recessed part of the cam contacts the pulley during rotation, the spring rebounds. This spring contraction and rebound causes the inlet to vibrate left and right, preventing the key blank from clogging the bottom. At the outlet of the part, after the key blank slides into the conveying pipe from the inlet, the magnet attracts the key blank, preventing damage from collisions between key blanks. At the same time, the key blank slowly slides into the hopper. After contacting the key blanks inside the hopper, it is placed horizontally. The vibration anti-blocking and magnet attraction design can effectively avoid the problem of key jamming during turntable calibration, ensuring accurate positioning of a single key. The design of the key lying flat after unloading further prevents vertical blockage caused by multiple keys stacking, making the entire feeding process smoother, reducing downtime for adjustment, and improving production continuity and processing stability.

[0010] The present invention is further configured such that a slider is bolted to the left side of the bottom of the inlet, and a groove is provided in the middle of the top of the conveying pipe, and the inside of the groove is slidably connected to the surface of the slider.

[0011] The above technical solution uses sliders and grooves to limit the movement of the inlet.

[0012] The present invention is further configured such that a magnet is embedded in the front end of the inner wall of the conveying pipe.

[0013] The above technical solution involves using magnets to prevent damage from collisions between key blanks while allowing the key blanks to slowly slide into the hopper.

[0014] The present invention is further configured such that a damper is sleeved inside the spring.

[0015] The above technical solution involves setting a damper to limit the movement of the spring.

[0016] The present invention is further configured such that there is a gap between the turntable and the fixed plate.

[0017] The above technical solution, by setting a gap, can prevent the turntable from rubbing against the fixed plate when rotating.

[0018] The present invention is further configured such that support columns are bolted to both sides of the top of the base, and the top of the support columns is bolted to both sides of the bottom of the fixing plate.

[0019] The above technical solution, by setting up support pillars, can stabilize and fix the plate.

[0020] The present invention is further configured such that a support leg is bolted to the bottom of the base.

[0021] The above technical solution, by setting out support legs, can stabilize the mechanism.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model can significantly improve processing efficiency and accuracy by achieving consistent feeding direction, correcting the key orientation, avoiding adjustment errors and wasted time, ensuring that the grinding surface of each key is aligned with the cutting tool, reducing the scrap rate, and simplifying the subsequent sorting process by feeding in a uniform direction, thus reducing production costs. It is especially suitable for mass production of standardized keys.

[0024] 2. This utility model effectively avoids the problem of keys getting stuck during turntable calibration through vibration anti-blocking and magnetic adsorption design, ensuring accurate positioning of a single key. The design of placing the key flat after feeding further prevents vertical blockage caused by multiple keys stacking, making the entire feeding process smoother, reducing downtime for adjustment, and improving production continuity and processing stability.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1:

[0036] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8A key grinding machine feeding mechanism includes a base 1, a motor 2 embedded in the center of the top of the base 1, a turntable 4 fixedly sleeved on the top of the output end of the motor 2, an opening 6 on the top of the turntable 4, a fixed plate 5 at the bottom of the turntable 4, a calibration port 7 at the rear end of the right side of the top of the fixed plate 5, a channel 8 embedded in the front end of the right side of the top of the fixed plate 5, a hopper 9 bolted to the top of the right side of the base 1, a conveying pipe 10 bolted to the top of the hopper 9, a slot 11 penetrating the center of the top of the fixed plate 5, and the surface of the output end of the motor 2 penetrating the interior of the slot 11, an anti-blocking mechanism on the left side of the top of the conveying pipe 10, and a collection box placed at the bottom of the calibration port 7. Key blanks are placed into the inlet. 15. The key blank enters the conveying pipe 10 from the inlet 15, and then enters the hopper 9. The key blank is placed horizontally inside the hopper 9 with an unknown orientation. The motor 2 drives the turntable 4 to rotate, and the rotation of the turntable 4 drives the opening 6 to rotate. When the opening 6 reaches the bottom of the hopper 9, the key blank naturally slides into the opening 6. The opening 6 drives the key blank to rotate and first pass through the calibration port 7. If the handle of the key blank faces the inside of the turntable 4, it matches the calibration port 7. The matched key blank falls from the calibration port 7 into the collection box at the bottom and is put back into the opening 6 for re-feeding. If the orientation does not match the calibration port 7, the key blank is rotated to the rightmost opening 6 of the turntable 4 and slides down the channel 8 to feed the grinding machine, achieving consistent feeding in the same direction.

[0037] refer to Figure 1 , Figure 2 There is a gap between the turntable 4 and the fixed plate 5. By setting the gap, the friction between the turntable 4 and the fixed plate 5 can be prevented when the turntable 4 rotates.

[0038] refer to Figure 2 The base 1 has two support columns 20 bolted to the top of the base 1, and the top of the support columns 20 is bolted to the two sides of the bottom of the fixed plate 5. By setting the support columns 20, the fixed plate 5 can be stabilized.

[0039] refer to Figure 1 , Figure 2 The bottom of the base 1 is bolted with a support leg 21, which can stabilize the mechanism.

[0040] Brief description of the usage process: Place a collection box at the bottom of calibration port 7, put the key blank into inlet 15, the key blank enters the conveying pipe 10 from inlet 15, and then enters the hopper 9. The key blank is placed horizontally inside the hopper 9 with an unknown orientation. Motor 2 drives turntable 4 to rotate, and the rotation of turntable 4 drives opening 6 to rotate. When opening 6 reaches the bottom of hopper 9, the key blank naturally slides into the opening 6. Opening 6 drives the key blank to rotate and first pass through calibration port 7. If the handle of the key blank faces the inside of turntable 4, it matches calibration port 7. The matched key blank falls from calibration port 7 into the collection box at the bottom, and is put into opening 6 again for re-feeding. If the orientation does not match calibration port 7, the key blank is rotated to the rightmost opening 6 of turntable 4 and slides down through channel 8 to feed the grinder, achieving consistent feeding in the same direction.

[0041] Example 2:

[0042] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 A key grinding machine feeding mechanism includes an anti-blocking mechanism comprising a second motor 3, which is embedded on the left side of the top of a conveying pipe 10. A cam 12 is fixedly sleeved on the top of the second motor 3. A pulley 13 is slidably connected to the right side of the surface of the cam 12. A spring 14 with an elastic coefficient of 10 N / m is bolted to the right side of the pulley 13. An inlet 15 is bolted to the right side of the spring 14. The key blank is poured into the inlet 15 and needs to enter the conveying pipe 10 from the inlet 15. The bottom of the inlet 15 and the inside of the conveying pipe 10 are set as flat openings, requiring the key blank to slide vertically against the wall into the conveying pipe 10. The second motor 3 drives the cam 12. As the cam 12 rotates, it drives the pulley 13 to slide. During the rotation, the protruding part of the cam 12 will squeeze and move the pulley 13. When the pulley 13 moves, the spring 14 contracts. When the concave part of the cam 12 contacts the pulley 13 during the rotation, the spring 14 rebounds. During the contraction and rebound of the spring 14, the inlet 15 vibrates left and right to prevent the key blank from blocking the bottom outlet. After the key blank slides into the conveying pipe 10 from the inside of the inlet 15, the magnet 18 attracts the key blank to prevent it from colliding and being damaged. At the same time, the key blank slowly slides into the hopper 9 and is placed horizontally after contacting the key blank inside the hopper 9.

[0043] refer to Figure 2 , Figure 3 A slider 16 is bolted to the left side of the bottom of the inlet 15, and a groove 17 is opened in the middle of the top of the conveying pipe 10. The inside of the groove 17 is slidably connected to the surface of the slider 16. By setting the slider 16 and the groove 17, the movement of the inlet 15 can be limited.

[0044] refer to Figure 7A magnet 18 is embedded in the front end of the inner wall of the conveying pipe 10. By setting the magnet 18, the key blanks are prevented from colliding and being damaged, while the key blanks are slowly slid into the hopper 9.

[0045] refer to Figure 2 , Figure 3 , Figure 6 A damper 19 is fitted inside the spring 14, which can limit the movement of the spring 14.

[0046] Brief description of the usage process: Pour the key blank into the inlet 15. The key blank needs to enter the delivery pipe 10 from the inlet 15. The bottom of the inlet 15 and the inside of the delivery pipe 10 are set as flat openings. The key blank needs to slide vertically against the wall into the delivery pipe 10. Motor 2 3 drives the cam 12 to rotate. The cam 12 drives the pulley 13 to slide. During the rotation of the cam 12, the raised part will squeeze and move the pulley 13. When the pulley 13 moves, the spring 14 will contract. During the rotation of the cam 12, the concave part will contact the pulley 13. When the spring 14 rebounds, the damper 19 limits the spring 14, with a damping coefficient of 5 N·s / m. During the spring 14's contraction and rebound, the inlet 15 vibrates left and right. The slider 16 and the slide 17 limit the movement of the inlet 15 to prevent the key blank from blocking the bottom outlet. After the key blank slides into the conveying pipe 10 from inside the inlet 15, the magnet 18 attracts the key blank, preventing damage from collisions between key blanks, while causing the key blank to slowly slide into the hopper 9. After contacting the key blank inside the hopper 9, it is placed horizontally.
