Description

Technical Field

[0001] This invention relates to the field of metal nail turning technology, specifically to a metal nail turning device. Background Technology

[0002] The automatic ejector metal nail turning equipment is a device that integrates automation technology and turning processes. It can automatically eject and fix metal nails during the turning process, thereby improving processing accuracy and production efficiency. Before processing, the equipment first places the metal nail raw material in a designated position and uses an automatic ejector device to eject and fix it. Then, the turning system starts working and performs precise turning of the metal nail according to the preset program and parameters. During the processing, the control system monitors the equipment's operating status and processing quality in real time to ensure the stability and accuracy of the processing process. Through automated control and a precise turning system, the processing accuracy and dimensional consistency of the metal nails can be ensured. Automated production reduces manual intervention and waiting time, improving production efficiency and output. This equipment can be widely used in the production of hardware products, fasteners, automotive parts and other industries.

[0003] In actual turning processes, the hardness of metal nail raw materials varies between different batches and for different needs. High-hardness materials have a strong resistance to cutting, requiring greater resistance to be overcome during the cutting process. As the material hardness increases, the cutting force also increases accordingly, which may increase the load on the machine tool and cutting tool, affecting cutting stability and tool life. High-hardness materials also generate more cutting heat during the cutting process because the cutting force is large, and more energy is required for material deformation. Most of this energy is converted into heat. The increase in cutting temperature may lead to thermal deformation of the workpiece, accelerated tool wear, and reduced cooling effect of the cutting fluid. In order to maintain the stability of the cutting process and reduce tool wear, it is necessary to appropriately reduce the cutting speed. This can reduce heat and wear during the cutting process. When cutting high-hardness materials, if the cutting speed is too high, it may lead to increased vibration of the machine tool and cutting tool, thereby affecting the machining accuracy and even creating certain safety hazards. Therefore, we propose an automatic ejector metal nail turning device. Summary of the Invention

The fixing base has stepped grooves, each layer of which is groove-like, with the depth gradually increasing from top to bottom. Vibration-detecting balls are located within the stepped grooves. A rotating rod is rotatably mounted within the fixing base, and a connecting rope is wound around the rotating rod. One end of the connecting rope is fixedly connected to the end of the rotating rod, and the other end is fixedly connected to the vibration-detecting balls. A reset knob is fixedly mounted at one end of the rotating rod. An adjustment knob for controlling the operating speed of the power base and motor is slidably mounted within the fixing base. One end of the adjustment knob is rotatably connected to the rotating rod, and the other end is fixedly connected to the inner wall of the fixing base by a third spring.

[0007] Preferably, each platform in the stepped groove is fixedly installed with a sensor plate at its bottom, and a second cylinder whose extension and retraction are controlled by the sensor plate is fixedly installed on the tool holder. Each turning tool has a reinforcing plate on both sides, and a telescopic column is fixedly installed at one end of each reinforcing plate.

The tool holder has several stepped plates that cooperate with the wedge blocks, and each stepped plate is fixedly installed at the output end of the second cylinder.

[0008] Preferably, an electromagnetic block is slidably mounted on the sleeve, and the electromagnetic block corresponds one-to-one with the fixed block. Each electromagnetic block is provided with an electromagnetic groove, and a limit post is slidably mounted in each electromagnetic groove. Each limit post is fixedly connected to the inner wall of the corresponding electromagnetic groove with a first spring. Each fixed block is provided with a slot for limiting the limit post. A limit ring for limiting the electromagnetic block is slidably mounted in the fixed seat.

[0009] Preferably, a cooling device is fixedly installed on the lathe, and a plurality of nozzles with liquid output controlled by an adjustment knob are fixedly installed on the cooling device. A bracket for fixing the nozzles is fixedly installed on the lathe, and a collection frame is slidably installed on the cooling device. A plurality of filter holes for filtering coolant are provided at the bottom of the collection frame.

[0010] Preferably, the fixed base is provided with a receiving card, a pusher rod is fixedly installed at one end of the receiving card, a storage tray for storing metal nail raw materials is fixedly installed on the fixed base, the outlet of the storage tray corresponds to the inlet of the receiving card, and a baffle is fixedly installed on the receiving card to prevent the raw materials in the storage tray from rolling off.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention utilizes stepped grooves and vibration detection balls to detect vibrations during the turning process. When the hardness of the metal nail raw material is high, the vibration generated by the fixed seat increases. The vibration detection ball will be vibrated and detach from the top of the stepped groove, and fall into different steps of the corresponding stepped groove according to the vibration amplitude. Pulling the pull rod and its end adjustment knob will reduce the speed of the power seat driving the tool holder, thus slowing down the turning speed. At the same time, the cooling device sprays more coolant, improving the cooling effect.

[0018] This invention utilizes an adjustment knob to control the second cylinder to push the stepped block to different degrees of movement, and controls the movement position of the stepped block according to the position of the vibration detection ball falling into the stepped groove. The cooperation between the different inclined surfaces of the stepped block and the wedge block causes the telescopic column to be compressed to different degrees, applying different pressures to the reinforcing plate, and reinforcing the tool to different degrees, thereby improving turning stability and preventing the tool from being damaged due to continuous excessive pressure.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-13This invention provides a technical solution: a metal nail turning device, including a lathe 1, a fixed seat 7 fixedly mounted on the lathe 1, a motor 12 fixedly mounted on the fixed seat 7, a sleeve 13 fixedly mounted at the output end of the motor 12, a first cylinder 14 fixedly mounted on the inner wall of the sleeve 13, and several fixed blocks 22 fixedly mounted at the output end of the first cylinder 14. A clamping block 28 for holding metal nails is slidably mounted between each pair of adjacent fixed blocks 22. During turning, the motor 12 starts, driving the sleeve 13 at its output end to rotate, and driving the first cylinder 14 and the fixed blocks 22 to rotate synchronously. The clamping blocks 28 are limited by the fixed blocks 22, causing the clamping blocks 28 to hold the metal nail material and rotate for turning. Each clamping block 28 has a sliding column 30 fixedly mounted on both sides, and each fixed block 22 has a sliding groove 31 on both sides for limiting the sliding column 30. Several wedge-shaped seats 26 are fixedly mounted on the inner wall of the sleeve 13. Each seat 26 corresponds to a locking block 28, and one end of each locking block 28 is set in a wedge shape to cooperate with the wedge seat 26. A guide strip 27 is fixedly installed on the inclined surface of each wedge seat 26. One end of each locking block 28 is provided with a guide groove 29 for limiting the guide strip 27. A slide cylinder 24 for ejecting material is slidably installed at the output end of the first cylinder 14. A second spring 25 is fixedly installed inside the slide cylinder 24, and one end of the second spring 25 is fixedly connected to the first cylinder 14. At the output end, when the turning is completed and the material is unloaded, the motor 12 stops working, and then the first cylinder 14 starts, pushing the fixed block 22 and the clamping block 28 outward. Through the cooperation between the inclined surface of the wedge seat 26 and the end of the clamping block 28, the clamping block 28 moves along the slide groove 31 while moving outward from the sleeve 13, and releases the clamping of the metal nail material. The elastic force of the second spring 25 pushes the slide cylinder 24 outward from the sleeve 13 and pushes out the metal nail material, realizing automatic material ejection.

[0035] A receiving card 9 is provided on the fixed base 7, and a pusher rod 10 is fixedly installed at one end of the receiving card 9. A storage tray 8 for storing metal nail raw materials is fixedly installed on the fixed base 7. The outlet of the storage tray 8 corresponds to the inlet of the receiving card 9. A baffle 11 is fixedly installed on the receiving card 9 to prevent the raw materials in the storage tray 8 from rolling off. When feeding, the metal nail raw materials in the storage tray 8 will roll off into the receiving card 9 under gravity, and only one metal nail raw material can be stored in the receiving card 9 at a time. Then the receiving card 9 will descend and align with the center position of the sleeve 13. The baffle 11 will descend with the receiving card 9 to prevent the metal nail raw materials in the storage tray 8 from rolling off. The pusher rod 10 will then push the metal nail raw materials out of the receiving card 9 and into the sleeve 13. The metal nail raw materials will first contact the sliding cylinder 24 and make the sliding cylinder... As the slide cylinder 24 moves into the sleeve 13, the second spring 25 will also be compressed. When the slide cylinder 24 moves to the bottom of the output end of the first cylinder 14, it will cause the first cylinder 14 to retract, driving the fixed block 22 and the clamping block 28 to move into the sleeve 13. At the same time, the guide groove 29 limits the guide bar 27, causing the clamping block 28 to move along the slide groove 31 and clamp the metal nail material. Due to the limiting of the metal nail material by the clamping block 28, the elastic force of the second spring 25 cannot push the slide cylinder 24 and the metal nail material out. The feeding is completed. Electromagnetic blocks 15 are slidably installed on the sleeve 13. The electromagnetic blocks 15 correspond one-to-one with the fixed blocks 22. Each electromagnetic block 15 is provided with an electromagnetic groove 19. Each electromagnetic groove 19 is slidably installed with a limit post 21. Each limit post 21 Each fixed block 22 is fixedly connected to the inner wall of the corresponding electromagnetic groove 19 with a first spring 20. Each fixed block 22 is provided with a slot 23 for limiting the limiting post 21. A limiting ring 16 for limiting the electromagnetic block 15 is slidably installed in the fixed base 7. Each electromagnetic block 15 is provided with a ball 17 at both ends. Each limiting ring 16 is provided with annular grooves 18 on both sides of its inner wall for limiting the ball 17. When no material is loaded, the position of the limiting ring 16 is adjusted according to the size of the metal nail material. The limiting ring 16 limits the electromagnetic block 15, and the position of the electromagnetic block 15 on the sleeve 13 is adjusted synchronously. The slot 23 on the fixed block 22 limits the limiting post 21 in the electromagnetic block 15. The retraction range of the fixed block 22 and the slot 28 is adjusted to allow the metal nail material to be loaded. It can be firmly clamped, and the fixing block 22 and the locking block 28 are not easy to slide. When the fixing block 22 needs to slide, the limiting post 21 is driven by electromagnetic induction to slide into the electromagnetic groove 19, and the first spring 20 is compressed. When the fixing block 22 moves to the appropriate position, the electromagnetic force is released, the limiting post 21 is ejected by the elastic force of the first spring 20 and inserted into the locking groove 23, and the positions of the fixing block 22 and the locking block 28 are fixed. When the motor 12 drives the sleeve 13 to move, the electromagnetic block 15 will rotate synchronously with the sleeve 13. Through the cooperation of the ball 17 and the annular groove 18, the friction between the electromagnetic block 15 and the inner wall of the limiting ring 16 during the rotation is reduced. A cooling device 2 is fixedly installed on the lathe 1 (the cooling device 2 is a known existing structure).Therefore, this invention will not be described in detail further. Several nozzles 3 are fixedly installed on the cooling device 2. A bracket 4 for fixing the nozzles 3 is fixedly installed on the lathe 1. A collection frame 5 is slidably installed on the cooling device 2. Several filter holes 6 for filtering coolant are provided at the bottom of the collection frame 5. During the turning process, the nozzles 3 spray coolant to cool the machine. After turning, the ejected metal nails fall into the collection frame 5 below. Excess coolant returns to the cooling device 2 through the filter holes 6 at the bottom of the collection frame 5 for recycling.

[0036] A power base 43 is fixedly mounted on the lathe 1. A tool post 44 is slidably mounted on the power base 43. The tool post 44 has several tool slots 49, each containing a different turning tool 47. Each turning tool 47 has anti-slip pads 48 fixedly mounted on both sides. Each turning tool 47 also has fixing plates 45 on both sides, each fixing plate 45 being fixedly mounted on the tool post 44. Each fixing plate 45 has several screws 46 threaded onto it for fixing the turning tool 47. After placing the turning tool 47 and the pads 48 into the corresponding tool slots 49, the screws 46 are tightened. The turning tool 47 is fixed to the tool post 44 by the clamping of the screws 46 on both sides. A stepped groove 32 is provided in the fixing seat 7. Each layer of the stepped groove 32 is designed in a trench-like pattern, with the depth gradually increasing from top to bottom. Vibration-detecting balls 34 are installed within the stepped groove 32. A rotating rod 35 is rotatably mounted within the fixed base 7, with a connecting rope 36 wound around it. One end of the connecting rope 36 is fixedly connected to the end of the rotating rod 35, and the other end is fixedly connected to the vibration-detecting balls 34. A knob 42 for resetting the rotating rod 35 is fixedly installed at one end. An adjusting knob 38 for controlling the operating speed of the power base 43 and the motor 12 is slidably installed within the fixed base 7. One end of the adjusting knob 38 is rotatably connected to the rotating rod 35, and the other end is fixedly connected to the inner wall of the fixed base 7 by a third spring 39. A protrusion 40 is fixedly installed at one end of the rotating rod 35, and a threaded groove 4 is provided within the fixed base 7 for limiting the movement of the protrusion 40. 1. The rotating rod 35 is provided with a spiral groove 37 for limiting the connecting rope 36. The pitch of the spiral groove 37 is the same as the pitch of the threaded groove 41. Depending on the hardness of the metal nail material, the fixed seat 7 will vibrate to different degrees during the turning process. According to the amplitude of the vibration, the vibration detection ball 34 will move randomly in the stepped groove 32. When the vibration reaches a certain amplitude, the movement amplitude of the vibration detection ball 34 will cause it to move away from the limit of the top platform of the stepped groove 32, and fall into different platforms in the stepped groove 32 according to the vibration amplitude of the fixed seat 7. When the vibration detection ball 34 moves downward in the stepped groove 32, it will drive one end of the connecting rope 36 to move and cause the rotating rod 35 to rotate. Through the limitation of the protrusion 40 by the threaded groove 41, the rotating rod 35 drives the knob 42 to rotate. While moving outward from the fixed base 7, the adjusting knob 38 slides within the fixed base 7, stretching the third spring 39. The elasticity of the third spring 39 keeps the connecting rope 36 taut, preventing the vibration detection ball 34 from pulling out too much of the connecting rope 36 during movement, making it impossible to retract. According to the sliding distance of the adjusting knob 38, the operating speed of the power base 43 and the motor 12 decreases successively, reducing the turning speed, reducing the wear of the turning tool 47, and the heat generated during the turning process. At the same time, the cooling device 2 is controlled to spray more coolant from the nozzle 3 for cooling. When a batch of metal nails is turned and the next batch is processed, the knob 42 is rotated inward from the fixed base 7. Since the pitch of the spiral groove 37 is the same as the pitch of the thread groove 41, when the knob 42 drives the rotating rod 35 to reverse,The connecting rope 36 is also retrieved and re-wound along the spiral groove 37. Simultaneously, the vibration detection ball 34 is pulled back to the top of the stepped groove 32. The adjusting knob 38 and the third spring 39 are reset. A sensor plate 33 is fixedly installed at the bottom of each platform in the stepped groove 32. A second cylinder 50, whose extension and retraction amplitude is controlled by the sensor plate 33, is fixedly installed on the tool holder 44. Reinforcing plates 54 are provided on both sides of each turning tool 47. A telescopic column 53 is fixedly installed at one end of each reinforcing plate 54. A through groove 56 is provided on the tool holder 44, and the telescopic column 53 passes through the through groove 56. Several limiting holes 55 are provided inside the tool holder 44 to limit the telescopic column 53. Each limiting hole 55 corresponds one-to-one with a telescopic column 53. A wedge block 51 is fixedly installed at one end of each telescopic column 53. Several stepped grooves that cooperate with the wedge blocks 51 are provided inside the tool holder 44. Each step plate 52 is fixedly installed at the output end of the second cylinder 50. After the vibration detection ball 34 falls into different platforms within the step groove 32, the corresponding sensing plate 33 will be sensed, causing the second cylinder 50 to extend a corresponding distance. Through the cooperation of different inclined surfaces of the step plate 52 with the inclined surface of the wedge block 51, and the limiting hole 55 limiting the telescopic column 53, the wedge block 51 is pushed towards the reinforcing plate 54 and the telescopic column 53 is compressed. Depending on the different movement amplitudes of the step plate 52, the telescopic column 53 will be compressed to different degrees. The reinforcing plate 54 reinforces the turning tool 47 with different forces. The higher the hardness of the metal nail material, the greater the vibration, and the greater the reinforcing force applied by the reinforcing plate 54. This can effectively improve the stability of turning and avoid continuously applying excessive reinforcing force to the turning tool 47, which could lead to damage to the turning tool 47.

[0037] Specifically, firstly, the turning tool 47 and the backing plate 48 need to be placed into the corresponding tool slot 49, and then the screw 46 is tightened. The turning tool 47 is fixed to the tool holder 44 by the clamping of the screws 46 on both sides. At the same time, when no material is loaded, the position of the limiting ring 16 is adjusted according to the size of the metal nail material. The limiting ring 16 limits the electromagnetic block 15, and the position of the electromagnetic block 15 on the sleeve 13 is adjusted synchronously. When loading material, the metal nail material in the storage tray 8 will roll down into the receiving card 9 under gravity. Only one metal nail material can be stored in the receiving card 9 at a time. Then the receiving card 9 will descend and align with the center position of the sleeve 13. The baffle 11 will descend with the receiving card 9 to prevent the metal nail material in the storage tray 8 from rolling down. The push rod 10 then... The metal nail material is ejected from the receiving card 9 and pushed into the sleeve 13. The metal nail material will first contact the slide cylinder 24, causing the slide cylinder 24 to move into the sleeve 13. The second spring 25 will also be compressed. When the slide cylinder 24 moves to the bottom of the output end of the first cylinder 14, it will cause the first cylinder 14 to retract, driving the fixing block 22 and the clamping block 28 to move into the sleeve 13. At the same time, the guide groove 29 limits the guide bar 27, causing the clamping block 28 to move along the slide groove 31 and clamp the metal nail material. Due to the clamping block 28 limiting the metal nail material, the elastic force of the second spring 25 cannot eject the slide cylinder 24 and the metal nail material. At the same time, the clamping groove 23 on the fixing block 22 limits the limiting post 21 in the electromagnetic block 15. Adjusting the fixing block 22 and the clamping block 28... The 8-degree retraction range ensures the metal nail material is firmly clamped, preventing slippage between the fixing block 22 and the locking block 28. When the fixing block 22 needs to slide, the limiting post 21 slides into the electromagnetic groove 19 under electromagnetic force through electromagnetic induction, compressing the first spring 20. When the fixing block 22 reaches the appropriate position, the electromagnetic force is released, and the limiting post 21 pops out under the elastic force of the first spring 20 and inserts into the locking groove 23, fixing the positions of the fixing block 22 and the locking block 28. When the motor 12 drives the sleeve 13 to move, the electromagnetic block 15 rotates synchronously with the sleeve 13. During turning, the motor 12 starts, driving the output sleeve 13 to rotate, and driving the first cylinder 14 and the fixing block 22 to rotate synchronously, thus limiting the locking block 28 through the fixing block 22. The clamping block 28 holds the metal nail material and rotates it for machining. During the machining process, the fixed seat 7 will vibrate to varying degrees. Depending on the amplitude of the vibration, the vibration detection ball 34 will move randomly within the stepped groove 32. When the vibration reaches a certain amplitude, the movement of the vibration detection ball 34 will cause it to move away from the limit of the top platform of the stepped groove 32 and fall into different platforms within the stepped groove 32 according to the vibration amplitude of the fixed seat 7. When the vibration detection ball 34 moves downwards in the stepped groove 32, it will drive one end of the connecting rope 36 to move and cause the rotating rod 35 to rotate. Through the limit of the protrusion 40 by the threaded groove 41, the rotating rod 35 drives the knob 42 to rotate and move outwards from the fixed seat 7, and causes the adjusting knob 38 to slide within the fixed seat 7. The third spring 39 is stretched.Furthermore, the elasticity of the third spring 39 keeps the connecting rope 36 taut, preventing the vibration detection ball 34 from pulling out too much of the connecting rope 36 during its movement and making it impossible to retract. According to the sliding distance of the adjusting knob 38, the operating speed of the power seat 43 and the motor 12 decreases successively, reducing the turning speed. Simultaneously, the cooling device 2 controls the nozzle 3 to spray more coolant for cooling. After the vibration detection ball 34 falls into different platforms within the stepped groove 32, the corresponding sensing plate 33 will be sensed, causing the second cylinder 50 to extend a corresponding distance. Through the cooperation of different inclined surfaces of the stepped plate 52 with the inclined surface of the wedge block 51, and the limiting hole 55 limiting the telescopic column 53, the wedge block 51 is pushed against the reinforcing plate 54, and the telescopic column 53 is compressed. Depending on the different movement amplitudes of the stepped plate 52, the telescopic column 53 will be compressed to varying degrees. The reinforcing plate 54 reinforces the turning tool 47 with different forces. The higher the hardness of the metal nail material, the more vibration is generated. The greater the movement, the greater the reinforcing force applied by the reinforcing plate 54. When the turning is completed, the motor 12 stops working, and then the first cylinder 14 starts, pushing the fixed block 22 and the clamping block 28 outward. Through the cooperation between the inclined surface of the wedge seat 26 and the end of the clamping block 28, the clamping block 28 moves along the slide groove 31 while moving outward from the sleeve 13, releasing the clamping of the metal nail material. The elastic force of the second spring 25 pushes the slide cylinder 24 outward from the sleeve 13 and pushes out the metal nail material. The pushed-out metal nail falls into the collection frame 5 below. When processing the next batch, the knob 42 is rotated inward from the fixed seat 7. Since the pitch of the spiral groove 37 is the same as the pitch of the thread groove 41, when the knob 42 drives the rotating rod 35 to reverse, the connecting rope 36 is also retracted and re-wound along the spiral groove 37.
