Abstract
Description
Technical Field
[0001] This invention relates to the field of automatic tapping rod reset mechanism technology, and in particular to an automatic tapping rod reset mechanism and a tapping machine. Background Technology
[0002] Most existing automated tapping machines are large-scale devices, and they need to retract after tapping before the nut can be replaced and the next tapping process can begin. There is also another type of small tapping machine where the tapping rod is movable. Manual loading and unloading is required, and the dropped tapping rod is inserted into the nut to be tapped. Then, the tapping drive shaft slowly rotates down and engages with the tapping rod to perform tapping. After tapping, the tapping rod falls off. Although this type of tapping machine saves the retraction time and improves efficiency, the manual insertion of the tapping rod and the manual replacement of the nut result in a lower overall precision standard of the produced nuts and a reduction in production efficiency. Summary of the Invention
[0003] Therefore, it is necessary to provide an automatic tapping rod reset mechanism and a tapping machine to address the technical problems of low product accuracy and low production efficiency.
[0004] To achieve the above objectives, the present invention provides an automatic tapping rod reset mechanism, comprising: Rotating disk; The rotating mechanism includes a rotating ring, which is rotatably mounted on a rotating disk. A guide frame is mounted on the rotating ring, and a clamping block is slidably engaged inside the guide frame. Two clamping blocks are slidably engaged on the same rotating ring. A lever is rotatably mounted on the rotating disk. The fixed mechanism includes an arc-shaped plate, which drives the lever to swing, thereby causing the rotating ring to rise and fall.
[0005] By adopting the above technical solution, when the rotating disk rotates, the dial plate can rotate accordingly. When the dial plate rotates to the arc plate, the arc plate can press down the end of the dial plate that is away from the rotating disk and is tilted down due to its smaller weight. Thus, the tilted end of the dial plate can lift the clamping block that is slidably locked in the guide frame by abutting against the rotating ring. The rotating ring needs to rotate synchronously with the tapping rod so that after the tapping rod falls, it can be accurately locked between the two clamping blocks without inaccurate clamping position due to rotational deviation. The large distance between the bottom of the two guide frames results in a large initial distance between the two clamping blocks. As the clamping blocks rise, the two clamping blocks can gradually approach and finally clamp the bottom square of the tapping rod before continuing to rise, lifting the tapping rod for reset. Thus, by automatically resetting the tapping rod, the tapping accuracy is improved while also increasing production efficiency.
[0006] Optionally, it also includes a feeding mechanism, which includes several fixed rings, which are fixedly mounted on the rotating disk. The fixed rings and the rotating rings are concentrically arranged. A feeding plate is rotatably mounted on the rotating disk. Two pairs of separation plates are slidably engaged on the feeding plate. The two separation plates are connected by an elastic component.
[0007] By adopting the above technical solution, the fixing ring is used to place and limit the nut to be tapped. Since the fixing ring and the rotating ring are concentrically set, the tapping rod can accurately fall between the clamping blocks in the guide frame after tapping. When the clamping blocks drive the tapping rod to rise, the tapping rod can lift the tapped nut together through the contact between the upper thread of the tapping rod and the inner thread of the nut. At this time, the blanking plate can be driven to deflect, so that the two separation plates located on both sides of the fixing ring can be lifted initially. After being lifted, due to the pulling of the elastic component, the two symmetrically set separation plates can move towards the center. When the plates are brought close together, the separating plate can come into contact with the tapped nut as the cutting plate deflects. This allows the nut to detach from the tapping rod, ultimately causing it to slide down the cutting plate and completing the automatic unloading of the tapped nut. When the cutting plate is not driven to deflect, the separating plate can slide to both sides of the fixing ring due to its own weight and the rounded corners below, thus not affecting the nut loading and tapping. After the separating plates are lifted and brought close together, there is still a certain distance between them to avoid the tapping rod that rises and resets, but the distance is not enough to cause the nut to deflect and fall.
[0008] Optionally, the feeding mechanism further includes a tapping rod with a lifting groove, and a lifting block is hinged in the lifting groove. When the lifting block deflects, one end of the lifting block abuts against the lifting groove.
[0009] By adopting the above technical solution, when the tapping rod is moved upward by the clamping block, the lifting block can tilt and deflect due to its own weight. The inner end of the deflected block can then abut against the inner wall of the lifting groove, so that the outer end of the lifting block can abut against the bottom edge of the tapped nut and lift it up, reducing thread wear caused by thread contact. When the tapping rod falls normally after tapping, the lifting block will retract into the lifting groove due to the collision with the nut, without affecting the normal descent of the tapping rod.
[0010] Optionally, the fixing mechanism further includes a guide plate, which has a guide groove and a discharge port, and a guide block is installed on the unloading plate, with the guide block cooperating with the guide groove.
[0011] By adopting the above technical solution, when the unloading plate passes the guide plate, it will be deflected due to the limit of the guide block by the guide groove on its upper part. When the deflected unloading plate passes the discharge port, the nuts carried on it can be discharged from the discharge port by tilting. The unloading plates are all fixedly installed with baffles to prevent the nuts from sliding out from the side.
[0012] Optionally, the bottom of the separating plate is provided with rounded corners, and the shape of the separating plate is adapted to the fixing ring.
[0013] By adopting the above technical solution, the separation plates can separate from each other by their own weight, and the rounded corners can reduce the friction between them and the fixing ring. When the separation plates separate and are stuck on both sides of the fixing ring, the edges of the separation plates and the hexagonal grooves inside the fixing ring are aligned, so that the two separation plates can better abut against the nut after shrinking.
[0014] Optionally, a drive shaft is rotatably mounted on the rotating disk, and a lifting shaft is slidably engaged inside the drive shaft. The bottom of the lifting shaft is provided with a square slot adapted to a tapping rod, and an electromagnet is installed in the square slot. The electromagnet's connection circuit is connected to the outside world through a conductive slip ring.
[0015] By adopting the above technical solution, the drive shaft can be driven to rotate, thereby driving the tapping rod to rotate and tap. The lifting shaft can be driven to rise and fall, thereby cooperating to drive the tapping rod to rise and fall for tapping. When the clamping block lifts the tapping rod and the separating plate removes the nut, the lifting shaft can descend, allowing the tapping rod to be locked into the square slot at the bottom of the lifting shaft. After being locked in, the electromagnet set on the inner wall of the square slot can be energized to attract and fix the tapping rod and drive it to rise and reset to the state of waiting to descend for tapping. The connection circuit of the electromagnet can be uniformly connected to the wires at the central shaft of the rotating disk, and connected to the external power supply at this point through a conductive slip ring.
[0016] Optionally, a gear is mounted on the drive shaft, a drive gear is rotatably mounted on the rotating disk, the gear meshes with the drive gear, a synchronous shaft is mounted on the drive gear, a synchronous gear is mounted on the synchronous shaft, and a driven gear is mounted on the rotating ring, the synchronous gear meshes with the driven gear.
[0017] By adopting the above technical solution, the drive gear can be rotated, thereby driving the gear and drive shaft to rotate for tapping. At the same time, in order to achieve synchronous rotation of the drive shaft and the rotating ring, when the drive gear rotates, the synchronous gear can drive the driven gear to rotate through the transmission of the synchronous shaft. Thus, the drive gear and synchronous gear of the same specification can drive the gear and driven gear of the same specification to rotate.
[0018] Optionally, the guide frame is provided with a lifting groove, and the distance between the lifting grooves on the two guide frames is larger at the top and bottom and smaller in the middle. The clamping block is slidably engaged in the lifting groove, and the clamping block is L-shaped.
[0019] By adopting the above technical solution, the distance between the two lifting slots is larger at the top and bottom and smaller in the middle. When the clamping blocks are driven to rise, the two clamping blocks can first approach each other to clamp the bottom square of the tapping rod and continue to be conveyed upward. When the rod is conveyed to a certain height, the top of the tapping rod can be attracted and clamped by the lifting shaft. The two clamping blocks can continue to rise to the top of the guide frame. During the continued rise, the two clamping blocks gradually separate, thus avoiding affecting the attraction and clamping effect of the lifting shaft. The L-shaped clamping block has a small gap between its side and the tapping rod, which reduces the possibility of deflection when the tapping rod rises.
[0020] Optionally, a fixed shaft is installed on the rotating ring, and both clamping blocks are slidably engaged with the fixed shaft.
[0021] By adopting the above technical solution, the clamping blocks can remain stable by sliding and engaging with the fixed shaft when they move closer or further apart due to the lifting groove.
[0022] The present invention also provides a tapping machine using the above-mentioned tapping rod automatic reset mechanism, comprising: a frame, a rotating disk rotatably mounted on the frame, a fixing mechanism fixedly mounted on the frame, a spray head mounted on the frame, and the spray head cooperating with a clamping block.
[0023] By adopting the above technical solution, the rotating disk can be driven to rotate on the frame. During rotation, the dial plate and the feed plate can collide with and deflect the fixing mechanism. The spray head can spray cleaning fluid to clean the debris adhering to the tapping rod and the clamping block, preventing debris from affecting the inaccurate reset. The preferred ratio of the positions occupied by the tapping rod rising again after tapping, removing the nut raised along with the tapping rod after rising, and manually reloading is 3:1:2 or 2:1:1.
[0024] This technical solution has at least the following beneficial effects: 1. By clamping and lifting the tapping rod with clamping blocks, the tapping rod can be automatically lifted and reset after tapping, thereby reducing the impact of manual insertion reset on accuracy and improving production efficiency; 2. By using a separation plate to guide the nut lifted by the tapping rod, automatic unloading of the nut after tapping is achieved, thereby further improving production efficiency.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Please see Figures 1 to 6 This application provides an automatic reset mechanism for a tapping rod, comprising: Rotating disk 1; The rotating mechanism 2 includes a rotating ring 21, which is rotatably mounted on the rotating disk 1. A guide frame 22 is fixedly mounted on the rotating ring 21. A clamping block 23 is slidably engaged in the guide frame 22. Two clamping blocks 23 are slidably engaged in the same rotating ring 24. A lever plate 25 is rotatably mounted on the rotating disk 1. The fixed mechanism 3 includes an arc-shaped plate 31, which drives the lever 25 to swing, thereby driving the rotating ring 24 to rise and fall.
[0028] When the rotating disk 1 rotates, the dial plate 25 can rotate accordingly. When the dial plate 25 rotates to the arc plate 31, the arc plate 31 can press down the end of the dial plate 25 that is away from the rotating disk 1 and is tilted down due to its smaller weight. Thus, the tilted end of the dial plate 25 can lift the clamping block 23 that is slidably locked in the guide frame 22 by abutting against the rotating ring 24. The rotating ring 21 needs to rotate synchronously with the tapping rod so that after the tapping rod falls, it can be accurately locked between the two clamping blocks 23, and the clamping position will not be inaccurate due to rotational deviation. The bottom distance of the two guide frames 22 is large, so that the initial distance between the two clamping blocks 23 is large. Thus, during the process of the clamping blocks 23 rising, the two clamping blocks 23 can gradually approach and finally clamp the bottom block of the tapping rod before continuing to rise, lifting the tapping rod for reset work. Thus, by automatically resetting the tapping rod, the tapping accuracy is improved and the production efficiency is also improved.
[0029] In one embodiment, please refer to Figure 1 and Figure 3 It also includes a feeding mechanism 4, which includes several fixed rings 41. The fixed rings 41 are fixedly installed and spaced apart on the rotating disk 1. The fixed rings 41 and the rotating rings 21 are concentrically arranged. A feeding plate 42 is rotatably installed on the rotating disk 1. Two pairs of separation plates 43 are slidably engaged on the feeding plate 42. The two separation plates 43 are connected by an elastic component 44. The elastic component 44 can be a durable and long-lasting spring.
[0030] By adopting the above technical solution, the fixing ring 41 is used to place and limit the nut to be tapped. Since the fixing ring 41 and the rotating ring 21 are concentrically set, the tapping rod can accurately fall between the clamping blocks 23 in the guide frame 22 after tapping. When the clamping blocks 23 drive the tapping rod to rise, the tapping rod can lift the tapped nut together through the contact between the upper thread of the tapping rod and the inner thread of the nut. At this time, the feeding plate 42 can be driven to deflect, so that the two separation plates 43 located on both sides of the fixing ring 41 can be lifted initially. After being lifted, due to the pulling of the elastic component 44, the two symmetrically set separation plates 43 can move towards When the plates are close together, the separating plate 43 can come into contact with the tapped nut during the deflection of the feeding plate 42, and pull it away from the tapping rod. Finally, the nut can slide down the feeding plate 42, thus completing the automatic feeding of the tapped nut. When the feeding plate 42 is not driven to deflect, the separating plate 43 can slide to both sides of the fixing ring 41 due to its own weight and the rounded corners below, so as not to affect the feeding and tapping of the nut. After the separating plates 43 are lifted and brought close together, there is still a certain distance between the two separating plates 43 to avoid the tapping rod that rises and resets, but the distance is not enough to make the nut deflect and fall.
[0031] In one embodiment, please refer to Figure 4The feeding mechanism 4 also includes a tapping rod 45, on which a lifting groove 46 is provided, and a lifting block 47 is hinged in the lifting groove 46. When the lifting block 47 deflects, one end of the lifting block 47 abuts against the lifting groove 46.
[0032] By adopting the above technical solution, when the tapping rod 45 is moved upward by the clamping block 23, the lifting block 47 can tilt and deflect due to its own weight. The inner end of the deflected block 47 can abut against the inner wall of the lifting groove 46, so that the outer end of the lifting block 47 can abut against the bottom edge of the tapped nut and lift it up, reducing the thread wear caused by the thread abutment. When the tapping rod falls normally after tapping, the lifting block 47 will retract into the lifting groove 46 due to the collision with the nut, which will not affect the normal descent of the tapping rod.
[0033] In one embodiment, please refer to Figure 1 The fixing mechanism 3 also includes a guide plate 32, on which a guide groove 33 and a discharge port 34 are provided. A guide block 35 is fixedly installed on the unloading plate 42, and the guide block 35 is configured to cooperate with the guide groove 33.
[0034] By adopting the above technical solution, when the unloading plate 42 passes the guide plate 32, it will be deflected by the guide groove 33 on the guide block 35. When the deflected unloading plate 42 passes the discharge port 34, the nuts it carries can be discharged from the discharge port 34 by tilting. The unloading plate 42 is fixedly installed with baffles to prevent the nuts from sliding out from the side.
[0035] In one embodiment, the bottom of the separating plate 43 is provided with rounded corners, and the shape of the separating plate 43 is adapted to the fixing ring 41.
[0036] By adopting the above technical solution, the separation plate 43 can separate from each other by its own weight, and the friction between the two separation plates 43 and the fixing ring 41 can be reduced by the rounded corners. When the separation plate 43 separates and is stuck on both sides of the fixing ring 41, the separation plate 43 is aligned with the edge of the hexagonal groove inside the fixing ring 41, so that the two separation plates 43 can better abut against the nut after shrinking.
[0037] In one embodiment, a drive shaft 11 is rotatably mounted on the rotating disk 1, and a lifting shaft 12 is slidably engaged inside the drive shaft 11. A square slot adapted to a tapping rod is provided at the bottom of the lifting shaft 12, and an electromagnet is fixedly installed inside the square slot. The connection circuit of the electromagnet is connected to the outside through a conductive slip ring.
[0038] By adopting the above technical solution, the drive shaft 11 can be driven to rotate, thereby driving the tapping rod to rotate and tap. The lifting shaft 12 can be driven to rise and fall, thereby cooperating to drive the tapping rod to rise and fall for tapping. When the clamping block 23 lifts the tapping rod and the separating plate 43 removes the nut, the lifting shaft 12 can descend, so that the tapping rod can be locked into the square slot at the bottom of the lifting shaft 12. After being locked, the electromagnet set on the inner wall of the square slot can be energized to attract and fix the tapping rod and drive it to rise and reset to the state of waiting to descend for tapping. The connection circuit of the electromagnet can be uniformly connected to the wires at the central shaft of the rotating disk 1, and connected to the external power supply at this point through the conductive slip ring.
[0039] In one embodiment, a gear 13 is fixedly mounted on the drive shaft 11, a drive gear 14 is rotatably mounted on the rotating disk 1, the gear 13 and the drive gear 14 are meshed together, a synchronous shaft 15 is fixedly mounted on the drive gear 14, a synchronous gear 16 is fixedly mounted on the synchronous shaft 15, and a driven gear 17 is fixedly mounted on the rotating ring 21, the synchronous gear 16 and the driven gear 17 are meshed together.
[0040] By adopting the above technical solution, the drive gear 14 can be driven to rotate, thereby driving the gear 13 and drive shaft 11 to rotate for tapping. At the same time, in order to achieve synchronous rotation of drive shaft 11 and rotating ring 21, when drive gear 14 rotates, through the transmission of synchronous shaft 15, synchronous gear 16 can drive driven gear 17 to rotate, so that drive gear 14 and synchronous gear 16 of the same specification can drive gear 13 and driven gear 17 of the same specification to rotate.
[0041] In one embodiment, please refer to Figure 7 The guide frame 22 has a lifting groove 26 inside. The distance between the lifting grooves 26 on the two guide frames 22 is larger at the top and bottom and smaller in the middle. The clamping block 23 is slidably engaged in the lifting groove 26. The clamping block 23 is L-shaped.
[0042] By adopting the above technical solution, the distance between the two lifting grooves 26 is larger at the top and bottom and smaller in the middle. When the clamping blocks 23 are driven to rise, the two clamping blocks 23 can first approach each other to clamp the bottom square of the tapping rod and continue to be conveyed upward. When the rod is conveyed to a certain height, the top of the tapping rod can be attracted and clamped by the lifting shaft 12. The two clamping blocks 23 can continue to rise to the top of the guide frame 22. During the continued rise, the two clamping blocks 23 gradually separate, thereby avoiding affecting the attraction and clamping effect of the lifting shaft 12. The L-shaped clamping block 23 has a smaller gap between its side and the tapping rod, which reduces the possibility of deflection when the tapping rod rises.
[0043] In one embodiment, a fixed shaft 27 is fixedly installed on the rotating ring 24, and both clamping blocks 23 are slidably engaged with the fixed shaft 27.
[0044] By adopting the above technical solution, the clamping blocks 23 can remain stable by sliding and engaging with the fixed shaft 27 when they move closer or further apart due to the lifting groove 26.
[0045] Please see Figure 7 This application also provides a tapping machine using an automatic tapping rod reset mechanism, comprising: The frame 5 has a rotating disk 1 rotatably mounted on it, and the fixing mechanism 3 is fixedly mounted on it. Spray heads are installed on the frame 5, and the spray heads are configured to cooperate with the clamping block 23.
[0046] By adopting the above technical solution, the rotating disk 1 can be driven to rotate on the frame 5. During rotation, the push plate 25 and the feeding plate 42 can collide with and deflect the fixing mechanism 3. The spray head can spray cleaning fluid to clean the debris adhering to the tapping rod and the clamping block 23, so as to avoid the debris affecting the inaccuracy of reset. The ratio of the workstations for tapping rod rising again after tapping, removing the nut raised together after tapping rod rises, and manual reloading is preferably 3:1:2 or 2:1:1.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
