Description

Technical Field

[0001] This application relates to the field of bolt processing technology, and in particular to a bolt tapping machine with automatic feeding function. Background Technology

[0002] A bolt is a mechanical part consisting of a head and a shank (a cylinder with external threads). It is used in conjunction with a nut to fasten two parts with through holes. It is widely used in electronic products, mechanical products, digital products, power equipment, etc. In the production process of bolts, the most common method of tapping the shank is to process the thread of the bolt by the interaction of a moving thread rolling plate and a fixed thread rolling plate. During the tapping process, the moving thread rolling plate reciprocates parallel to the bolt axis and interacts with the fixed thread rolling plate, thereby creating threads on the bolt. Before the shank is tapped, it is usually placed randomly, and an automatic feeding device is required to enable the shank to feed at a uniform speed and discharge in a quantitative manner.

[0003] Existing automatic feeding devices use stepped devices of varying widths to feed scattered bolt blanks step by step, which are then received by tilting hoppers. To ensure synchronization during feeding, the stepped plates and tilting hoppers are often driven by multiple sets of gears. The number of bolts received by the hopper each time is not fixed, so the load on the gears is different each time they rotate. After long-term operation, this will accelerate the wear of the gear shafts or teeth. In mild cases, it may cause asynchronous feeding time, affecting production efficiency. In severe cases, it may lead to damage to the mechanical structure or even cause production accidents. Summary of the Invention

As described above, the lubricating oil can be reused and recycled during operation.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention utilizes a feed assembly with recirculating lubrication. Three trapezoidal plates move synchronously upward within two baffles. The rightmost trapezoidal plate lifts multiple screws, and with the stroke of two additional hydraulic rods, the sliding plate moves away, causing the three trapezoidal plates to fall. Some screws are transported via the right-hand inclined plate to the middle trapezoidal plate of the next step. As the hydraulic rods reciprocate multiple times, the bolts are progressively transported to the leftmost inclined plate. The lubricating fluid collected in the second collection box continuously rises in level, lubricating the sliding plate, pulley, and the three trapezoidal plates. This solves the problem of gear wear caused by the different load weights in existing gear-driven equipment.

[0018] 2. This invention, through the installation of a newly designed transport component, allows the rotating groove to tilt clockwise along the front end of the right-side baffle. At this time, the screw slides into the curved groove via the rubber connector, activating multiple electric shafts to rotate clockwise, which in turn drives the track to rotate clockwise. The screw that reaches this point can move evenly to the other side of the curved groove. If there is a gap between two screws, the travel of the telescopic rod can be increased to block the head of the bolt, allowing the subsequent screws to fit tightly, thereby reducing the gap and ensuring uniform feeding in the subsequent tapping steps.

[0019] 3. This invention, by installing a separator component, allows the first motor to rotate the rhombus block clockwise. When the position of the rhombus block and the L-shaped block opposite each other is rotated to the short side, the spring will pull the L-shaped block away from the fixed seat, thereby allowing the bolt blocked in the groove to continue to the right. The separation time of the separator component is exactly the same as the tapping time of the tapping component, thus ensuring that only one bolt is tapped at a time, ensuring the synergy between the two components, thereby improving the tapping yield.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1-9 This embodiment of a bolt tapping machine with automatic feeding function includes a feeding assembly 1, which includes three support seats 11. A storage box 12 is fixedly installed on the top of the three support seats 11. The interior of the storage box 12 is a sloping design with one end higher than the other. Two baffles 13 are fixedly installed on the left end of the storage box 12. Three trapezoidal plates 14 are movably engaged between the two baffles 13. Three inclined plates 15 are fixedly installed between the three trapezoidal plates 14. A curved plate 16 is fixedly installed on the outer wall of the front baffle 13.

[0034] It also includes a linkage lubrication tapping mechanism, which includes a pushing component 2, which is fixedly installed at the bottom of the feeding component 1. The front and rear sides of the pushing component 2 are the discharge end and the feeding end, respectively. A transport component 3 is fixedly installed at the discharge end of the pushing component 2. A separating component 4 is fixedly installed at the tail end of the transport component 3. A lubrication component 5 is fixedly installed on the right side of the separating component 4. A tapping component 6 is fixedly installed on the front side of the lubrication component 5. A circulation component 7 is fixedly installed at the bottom of the tapping component 6. Three trapezoidal plates 14 are equidistantly and movably engaged within two baffles 13. The top of the three trapezoidal plates 14 is flat, and the bottom is an inclined surface with one end lower than the other. The width of the three trapezoidal plates 14 and the three inclined plates 15 gradually decreases from right to left at the top, while the longitudinal height continuously increases.

[0035] Under the influence of gravity, the screw will roll towards the trapezoidal plate 14. At this time, the stroke of the two hydraulic rods 21 is shortened. Through the two columns 22, the sliding plate 23 will move towards the direction of the transport component 3. The three trapezoidal plates 14 will move upward synchronously within the two baffles 13. The rightmost trapezoidal plate 14 will lift up multiple screws. After increasing the stroke of the two hydraulic rods 21, the sliding plate 23 will move away, and the three trapezoidal plates 14 will fall down. Some screws will be transported to the middle trapezoidal plate 14 of the next step through the right inclined plate 15. When the hydraulic rods 21 move back and forth multiple times, the bolts will be transported step by step to the leftmost inclined plate 15 until they fall into the rotating groove 25. The bolts that fall into the rotating groove 25 will be suspended due to the center of gravity, presenting a state where the screw is in the groove and the head is out. The lubricating fluid in the second liquid collection box 73 will continuously rise in level, which can also lubricate the operation of the sliding plate 23, pulley 24 and the three trapezoidal plates 14.

[0036] The pushing component 2 includes two first hydraulic rods 21, both of which are fixedly installed on the front side of the baffle 13. The telescopic ends of the two first hydraulic rods 21 are fixedly connected to columns 22. The bottom of the two columns 22 is fixedly connected to a sliding plate 23. The sliding plate 23 has an upper sloping surface design with one end higher than the other and abuts against the bottom surface of the three trapezoidal plates 14. A pulley 24 is fixedly installed on the top of the sliding plate 23. A rotating groove 25 is fixedly installed on the top of the pulley 24. The rotating shaft of the rotating groove 25 is movably hinged to the front baffle 13.

[0037] At this time, shortening the stroke of the two hydraulic rods 21 will cause the sliding plate 23 to move towards the direction of the transport component 3 via the two columns 22. The three trapezoidal plates 14 will move upward synchronously within the two baffles 13, increasing the stroke of the two hydraulic rods 21. The sliding plate 23 will move away, and the three trapezoidal plates 14 will fall.

[0038] The transport component 3 includes a base 31, which is fixedly installed on the front side of the rotating groove 25. A curved groove 32 is opened on the top of the base 31. Multiple electric shafts 33 are fixedly installed on the left side of the curved groove 32. Tracks 34 are sleeved on the outer edges of the multiple electric shafts 33. A fixing block 35 is fixedly installed on the right wall of the base 31. A telescopic rod 36 is inserted into the fixing block 35. The base 31 and the curved groove 32 are both L-shaped. A rubber connector 37 is fixedly connected to one end of the base 31 near the rotating groove 25. The other end of the rubber connector 37 is fixedly connected to the rotating groove 25.

[0039] The rotating groove 25 will tilt clockwise along the front end of the right side baffle 13. At this time, the screw will slide into the curved groove 32 through the rubber connector 37, and start multiple electric shafts 33 to rotate clockwise, which can drive the track 34 to rotate in the same clockwise direction. The screw that reaches this point can move evenly to the other side of the curved groove 32. If there is a gap between two screws, the travel of the telescopic rod 36 can be increased to block the head of the bolt once, so that the screws behind can be tightly attached to reduce the gap.

[0040] The separator component 4 includes a fixed base 41, which is fixedly installed on the right side of the base 31. A spring 42 is fixedly connected to the top of the fixed base 41, and an L-shaped block 43 is elastically connected to the other end of the spring 42. A first motor 44 is fixedly installed on the left side of the spring 42, and a rhombus-shaped block 45 is fixedly connected to the output shaft of the first motor 44. The contact position between the fixed base 41 and the L-shaped block 43 has a protrusion, and the L-shaped block 43 is slidably installed on the top of the protrusion. The rhombus-shaped block 45 is divided into a long side and a short side, and its outer edge abuts against the L-shaped block 43, which can change the position of the L-shaped block 43 under the rotational drive of the first motor 44.

[0041] The first motor 44 drives the diamond block 45 to rotate clockwise. When the diamond block 45 and the L-shaped block 43 are rotated to the short side, the spring 42 will pull the L-shaped block 43 away from the fixed seat 41, so that the bolt blocked in the groove 32 can continue to move to the right. The separation time of the separating component 4 is exactly the same as the tapping time of the tapping component 6, so that only one bolt is tapped each time.

[0042] The lubrication assembly 5 includes a first vertical plate 51, which is fixedly installed on the right side of the fixed base 41. A nozzle 52 is fixedly installed on the top of the first vertical plate 51, and a fixed groove plate 53 is fixedly installed on the inner wall of the first vertical plate 51.

[0043] During tapping, nozzle 52 sprays lubricant onto the bolt from top to bottom, serving two purposes: cooling and lubrication.

[0044] The tapping assembly 6 includes a second vertical plate 61, which is fixedly installed on the back of the first vertical plate 51. A collection box 62 is fixedly installed on the front side of the second vertical plate 61. A second motor 63 is fixedly installed on the top right side of the second vertical plate 61. The output shaft of the second motor 63 is fixedly connected to a rotating wheel 64. The eccentric shaft of the rotating wheel 64 is movably hinged to a connecting rod 65. A track 66 is fixedly installed on the inner left side of the second vertical plate 61. A movable slot plate 67 is slidably installed in the track 66. The back of the movable slot plate 67 is movably hinged to the other end of the connecting rod 65. Tapping slots are opened on the inner sides of both the fixed slot plate 53 and the movable slot plate 67.

[0045] The second motor 63 drives the rotating wheel 64 to rotate clockwise. The eccentrically driven connecting rod 65 can pull the movable slot plate 67 to move back and forth in the track 66. Through the grooves in the fixed slot plate 53 and the movable slot plate 67, the bolt is tapped. After tapping, it falls into the collection box 62 under the inertial motion of the movable slot plate 67 to complete the collection. The separation time of the separating component 4 is exactly the same as the tapping time of the tapping component 6, so it can be ensured that only one bolt is tapped each time.

[0046] The circulation component 7 includes a first liquid collection box 71, which is fixedly installed on the inner wall of the first vertical plate 51 and the second vertical plate 61. A first connecting pipe 72 is fixedly connected to the bottom of the first liquid collection box 71, and the other end of the first connecting pipe 72 is connected to a second liquid collection box 73. The second liquid collection box 73 is fixedly installed at the bottom of the sliding plate 23 and the curved plate 16. A second connecting pipe 74 is fixedly installed at the upper part of the middle of the right wall of the second liquid collection box 73. A filter 75 is fixedly installed at the middle of the second connecting pipe 74, and the tail end of the second connecting pipe 74 is fixedly connected to the first vertical plate 51.

[0047] The used lubricant is collected in the first collection box 71 and enters the second collection box 73 through the first connecting pipe 72. Also entering the second collection box 73 are the debris generated when the bolt is tapped. The debris will continuously settle in the second collection box 73, while the lubricant level in the second collection box 73 will continuously rise. It can also lubricate the operation of the sliding plate 23, pulley 24 and the three trapezoidal plates 14 until it flows into the second connecting pipe 74 installed at the top. After being filtered again by the filter 75, it is circulated to the nozzle 52 again.

[0048] Working principle;

[0049] When using this invention, the bolt blank is first placed in the storage box 12. Because the inside of the storage box 12 is designed with a slope that is higher at one end and lower at the other, the screw will roll towards the trapezoidal plate 14 under the influence of gravity. At this time, the stroke of the two hydraulic rods 21 is shortened. Through the two columns 22, the sliding plate 23 will move towards the direction of the transport component 3. The three trapezoidal plates 14 will move upward synchronously within the two baffles 13. The rightmost trapezoidal plate 14 will lift up multiple screws. After increasing the stroke of the two hydraulic rods 21, the sliding plate 23 will move away, and the three trapezoidal plates 14 will fall down. Some of the screws will be transported to the middle trapezoidal plate 14 of the next step through the right inclined plate 15. When the hydraulic rods 21 move back and forth multiple times, the bolts will be transported step by step to the leftmost inclined plate 15 until they fall into the rotating groove 25. The bolts that fall into the rotating groove 25 will be suspended due to the center of gravity, presenting a state where the screw is in the groove and the head is out.

[0050] The bottom of the rotating groove 25 is equipped with a pulley 24. When the hydraulic rod 21 moves the sliding plate 23 away, the rotating groove 25 will tilt clockwise along the front end of the right side baffle 13. At this time, the screw will slide into the curved groove 32 through the rubber connector 37, and start multiple electric shafts 33 to rotate clockwise, which can drive the track 34 to rotate in the same clockwise direction. The screw that reaches this point can move evenly to the other side of the curved groove 32. If there is a gap between two screws, the travel of the telescopic rod 36 can be increased to block the head of the bolt once, so that the screws behind can be tightly attached to reduce the gap.

[0051] When the bolt is transported to the separator assembly 4, it is blocked by the L-shaped block 43. The first motor 44 drives the diamond block 45 to rotate clockwise. When the diamond block 45 and the L-shaped block 43 are rotated to the short side, the spring 42 pulls the L-shaped block 43 away from the fixed seat 41, so that the bolt blocked in the groove 32 can continue to move to the right. When the screw reaches between the fixed groove plate 53 and the movable groove plate 67, the second motor 63 drives the rotating wheel 64 to rotate clockwise. The eccentrically driven connecting rod 65 can pull the movable groove plate 67 to move back and forth in the track 66. The bolt is tapped by the grooves in the fixed groove plate 53 and the movable groove plate 67. After tapping, the bolt falls into the collection box 62 under the inertial motion of the movable groove plate 67 to complete the collection. The separation time of the separator assembly 4 is exactly the same as the tapping time of the tapping assembly 6, so it can be ensured that only one bolt is tapped each time.

[0052] During tapping, nozzle 52 sprays lubricant onto the bolt from top to bottom, serving two purposes: cooling and lubrication. The used lubricant is collected in the first collection box 71 and flows through the first connecting pipe 72 into the second collection box 73. Also entering the second collection box 73 are the debris generated during the tapping process. The debris settles continuously in the second collection box 73, causing the lubricant level to rise. This lubrication also lubricates the operation of the sliding plate 23, pulley 24, and the three trapezoidal plates 14. Finally, the lubricant flows back into the second connecting pipe 74 installed at the top, where it is filtered again by the filter 75 and then circulated back to nozzle 52.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
