Technical Field

[0002] A nut tapping machine is a mechanical processing equipment that processes internal threads, screws or threads on the inner side of holes of various specifications of parts such as nuts and flanges with through holes or blind holes; a nut tapping machine is also called a nut tapping machine, a nut tapping machine, an automatic nut tapping machine, a fully automatic nut tapping machine, a tapping machine, and a tapping machine. It is called a nut tapping machine in the south and a nut tapping machine in the north.

[0003] In the tapping of nuts, there is a flat-push automatic tapping machine. When in use, the flat-push automatic tapping machine uses the operation of the cylinder to drive various structures to realize the operation of loading, pushing and other links. At present, in the use of flat-push automatic tapping machines, there are often multiple drive devices for operation, which will increase the cumbersomeness and inconvenience of subsequent maintenance, and also increase the cost of early synchronization debugging. In addition, when the cylinder drives the push rod to push the nut, the push rod pushes the nut to the desired position, and only relies on the moving range of the push rod to achieve the position of the nut under the drill bit. This link lacks a positioning structure for the nut, and it is necessary to calculate the inertia of the nut during the movement of the push rod, which brings inconvenience to the use of the tapping mechanism. Summary of the invention

[0004] The purpose of the present invention is to provide a high-precision positioning tapping mechanism for nut tapping, which has the advantage of being conducive to synchronizing the operation of the push rod and the cross bar, reducing the use of driving equipment, and at the same time reducing the cumbersome synchronization debugging before the use of the mechanism, thereby increasing the convenience of use of the tapping mechanism; realizing the positioning use of the tapping mechanism for the nut, increasing the stability and positioning accuracy in the tapping of the nut, and distinguishing it from the inconvenience of using the unlimited structure after the existing push rod pushes the nut to the required range.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a high-precision positioning tapping mechanism for nut tapping, comprising a tapping mechanism, the tapping mechanism comprising a supporting assembly and a tapping assembly, the supporting assembly comprising a base, the tapping assembly comprising a supporting frame, a moving mechanism is provided on the inner side of the base, the moving mechanism comprises a reciprocating mechanism, a rotating assembly and a driving assembly, a positioning mechanism is provided on one side of the moving mechanism, the positioning mechanism comprises an abutment assembly and a positioning assembly, the abutment assembly comprises an abutment block, and the positioning assembly comprises a transmission gear 1.

[0006] By adopting the above technical solution, when using the high-precision positioning tapping mechanism for nut tapping, the external vibrating feeder is preferably placed on one side of the base. Through the operation of the driving assembly, the rotating assembly will be driven to rotate, thereby driving the reciprocating mechanism to operate. The push rod and the cross bar will realize alternating movement. After the cross bar moves, the external vibrating feeder is used to feed the nut between the two limit blocks, and the cross bar returns to the initial position. Then the push rod pushes the nut between the limit blocks, pushing the untapped nut to the bottom of the drill bit, and pushing the nut that has been tapped in the previous round to a position close to the outside of the base, and the tapped nut that was originally close to the outside of the base will be pushed to achieve unloading. Then, with the use of the support assembly, a new round of tapping will be performed on the nut at the bottom of the drill bit. This setting is conducive to synchronizing the operation of the push rod and the cross bar, reducing the use of driving equipment, and at the same time reducing the cumbersome synchronization debugging before the use of the mechanism, and increasing the convenience of using the tapping mechanism. At the same time, when the high-precision positioning tapping mechanism is used for tapping the nut, the abutment assembly will be driven to operate in the process of the push rod pushing the nut, so that the positioning assembly cooperates with the tapped nut close to the outside of the base for positioning, and the push rod performs contact limit on the untapped nut. At this time, the tapping mechanism can be used to position the nut, thereby increasing the stability and positioning accuracy in nut tapping, which is different from the inconvenience of using the existing unlimited structure after the push rod pushes the nut to the required range.

The movement of the crossbar will drive the limit block to move, and an external vibrating feeder is set on one side of the base.

The rotation of vertical rod 1 and vertical rod 2 will drive half gear 1 and half gear 2 to rotate respectively. Half gear 1 and half gear 2 will intermittently drive full gear 1 and full gear 2 to rotate through teeth, wherein full gear 1 will drive rotating rod 1 to rotate, and full gear 2 will drive rotating rod 2 to rotate.

[0017] The present invention is further configured as follows: the driving assembly includes a rotating motor 2, the rotating motor 2 is fixedly connected to the inner side of the base, the output end of the rotating motor 2 is fixedly sleeved with a driving rod 1 through a coupling, the surface of the driving rod 1 is fixedly sleeved with a driving gear 1, the surface of the driving gear 1 is respectively meshed with a driving gear 2 and a driving gear 3, the interior of the driving gear 2 is fixedly sleeved with a driving rod 2 rotatably connected to the inside of the base, the surface of the driving gear 3 is meshed with a driving gear 4, the interiors of the driving gear 3 and the driving gear 4 are respectively fixedly sleeved with a support rod 1 and a support rod 2 rotatably connected to the base, the tops of the support rod 1 and the support rod 2 are respectively fixedly sleeved with a half gear 3 and a half gear 4, and the half gear 3 and the half gear 4 are mutually meshed with meshing gears fixedly sleeved with a connecting rod.

[0018] By adopting the above technical solution, the operation of the rotating motor 2 will drive the driving rod 1 to rotate, the driving rod 1 will drive the driving gear 1 to rotate synchronously, the driving gear 1 will drive the driving gear 2 to rotate through meshing, the driving rod 2 will support the driving gear 2, and cooperate with the driving gear 2 to rotate smoothly. The driving gear 1 and the driving gear 2 will respectively drive the driving gear 2 and the driving gear 3 to rotate. Among them, the driving gear 3 and the driving gear 4 will respectively drive the support rod 1 and the support rod 2 to rotate, and the support rod 1 and the support rod 2 will respectively drive the half gear 3 and the half gear 4 to rotate. And through the meshing of the gears, the meshing transmission of the meshing gears of the half gear 1 and the half gear 2 will be alternately staggered. And through the gear transmission characteristics, the rotation direction of the support rod 1 and the support rod 2 will be in the opposite state. In the transmission of the meshing gears of the half gear pair, the meshing gear and the connecting rod will rotate in the forward direction, and in the rotation of the meshing gears of the half gear 2 pair, the meshing gear and the connecting rod will rotate in the reverse direction.

[0019] The present invention is further configured as follows: there are two abutment blocks, which are respectively fixedly connected to both sides of the push rod, and one side of the side plate, the limit block and the template are all provided with a clamping groove for cooperating with the abutment block, the inner side of the template is provided with an abutment rod, the surface of the abutment rod is fixedly sleeved with a spring 1 fixedly sleeved with the inside of the base, one end of the abutment rod is fixedly installed with a fixing plate fixedly connected to the inside of the base, one side of the fixing plate is provided with a moving plate, one end of the moving plate is provided with a fixing block fixedly connected to the fixing plate, one side of the moving plate is provided with a guide rod penetrating the fixing block, and the surface of the guide rod is fixedly sleeved with a spring 2 fixedly connected to the fixing block.

[0020] By adopting the above technical solution, the abutment block will be driven to move during the movement of the push rod, and the abutment block is guided by the clamping groove, and during the movement of the abutment block, the push rod will preferentially contact the nut. Two nuts are placed in the middle of the template, one is the nut to be tapped, and the other is the tapped nut. After the tapping of the untapped nut is completed, the push rod pushes the nut waiting for feeding in the limit block, and pushes the nut close to the outside of the base to the unloading. During the movement of the push rod, the abutment block will contact the abutment rod, thereby causing the movement of the abutment rod, and the spring one cooperates with the abutment rod to return to the initial position after the movement, so as to facilitate the next use. The abutment rod will drive the fixed plate to move. In the subsequent movement of the shifting plate, the movement and guidance of the shifting plate will be realized by the guide rod, and the spring two cooperates with the movement of the shifting plate to shrink and stretch.

[0021] The present invention is further configured as follows: a slider is fixedly installed on one side of the movable plate, a sliding groove is opened on one side of the fixed plate for cooperating with the sliding of the slider, the other end of the movable plate is provided with a vertical rod one rotatably connected to the inner side of the base, an abutment plate is fixedly installed on the surface of the vertical rod one, a torsion spring fixedly connected to the inner side of the base is fixedly sleeved on the top of the vertical rod one, a clamping strip one is fixedly installed on one side of the abutment plate, and a clamping strip two for cooperating with the clamping strip one is fixedly installed on the other side of the movable plate.

[0022] By adopting the above technical solution, when the movable plate is moved by the fixed plate, the second clamping strip will contact the first clamping strip and abut against each other, and at the same time, the movable plate will have a movement tendency to approach the fixed block. At this time, the fixed plate continues to move under the influence of the abutment rod, and at the same time, the second spring is in a contracted state, and the abutment plate also approaches the fixed block. The abutment plate and one side of the fixed block both form mutually fitting inclined surfaces. When the inclined surfaces of the abutment plate and the fixed block contact each other, the angle of the abutment plate will slide. At this time, the abutment plate will adjust its angle around the vertical pole 1 as the center of the circle, and the rotation of the vertical pole 1 will cause the torsion spring to stretch. At the same time, the abutment strip 1 and the second clamping strip will cancel the abutment, and the force on the movable plate will be cancelled, which will cause the abutment plate to be ejected.

[0023] The present invention is further configured as follows: the transmission gear 1 and the vertical pole 1 are fixedly sleeved with each other, the surface of the transmission gear 1 is meshed with a transmission gear 2, the interior of the transmission gear 2 is fixedly sleeved with a vertical pole 2 rotatably connected to the inner side of the base, the surface of the transmission gear 2 is meshed with a transmission gear 3, the interior of the transmission gear 3 is fixedly sleeved with a vertical pole 3 that penetrates through the top of the base, the vertical pole 3 and the base are rotatably connected with each other, and a positioning plate is fixedly installed on the surface of the vertical pole 3.

[0024] With the above technical solution, the rotation of the vertical rod 1 will drive the transmission gear 1 to rotate, and the transmission gear 1 will drive the transmission gear 2 to rotate, wherein the vertical rod 2 supports the transmission gear 2 and rotates smoothly by cooperating with the transmission gear 2. The transmission gear 2 drives the transmission gear 3 to rotate, and the transmission gear 3 drives the vertical rod 3 and the positioning plate to rotate, so that the positioning plate limits the nut that is pushed to the outside of the base immediately after unloading, thereby realizing the positioning of the two nuts between the templates.

[0025] In summary, the present invention has the following beneficial effects: When using the high-precision positioning tapping mechanism for nut tapping, it is preferred to place the external vibrating feeder on one side of the base, and by rotating the operation of motor one, the push rod and the cross bar will be driven to achieve alternating movement. After the cross bar moves, the external vibrating feeder feeds the nut between the two limit blocks, and the cross bar returns to its initial position. The push rod then pushes the nut between the limit blocks, pushing the untapped nut to the bottom of the drill bit, and pushing the nut that has been tapped in the previous round to a position close to the outside of the base, while the tapped nut that was originally close to the outside of the base will be pushed to achieve unloading. This setting is conducive to synchronizing the operation of the push rod and the cross bar, reducing the use of drive equipment, and at the same time reducing the cumbersome synchronization debugging before the use of the mechanism, and increasing the convenience of using the tapping mechanism; When using the high-precision positioning tapping mechanism for tapping nuts, the positioning plate cooperates with the tapped nut near the outside of the base for positioning, and the push rod performs contact limit on the untapped nut. At this time, the tapping mechanism can be used to position the nut, thereby increasing the stability and positioning accuracy in nut tapping. This is different from the inconvenience of using the existing unlimited structure after the push rod pushes the nut to the required range. BRIEF DESCRIPTION OF THE DRAWINGS

When the push rod 1014 moves, the abutment block 3011 will be driven to move, and the abutment block 3011 is guided by the clamping groove 30116. When the abutment block 3011 moves, the push rod 1014 contacts the nut first. Two nuts are placed in the middle of the template 1012, one is a nut to be tapped, and the other is a tapped nut. After the untapped nut is tapped, the push rod 1014 pushes the nut waiting for feeding in the limit block 1016, and pushes the nut near the outside of the base 1011 to unload.

[0041] Brief description of the use process: When the high-precision positioning tapping mechanism for nut tapping is used, in the process of the push rod 1014 pushing the nut, the movement of the push rod 1014 will drive the abutment block 3011 to move, and the abutment block 3011 is clamped and guided in the clamping groove 30116, and in the movement of the abutment block 3011, the push rod 1014 preferentially contacts the nut, and two nuts are placed in the middle of the template 1012, one is the nut to be tapped, and the other is the tapped nut. After the tapping of the untapped nut is completed, the push rod 1014 pushes the nut waiting for feeding in the limit block 1016, and pushes the nut near the outside of the base 1011 to the unloading. In the movement of the push rod 1014, the abutment block 3011 will contact the abutment rod 3012, thereby causing the movement of the abutment rod 3012, and the spring 1 3013 cooperates with the abutment rod 3012 to return to the initial position after the movement, so as to facilitate the next use. The abutment rod 3012 will drive the fixed plate 3014 to move. In the subsequent movement of the moving plate 3015, the moving plate 3015 will be guided by the guide rod 3017, and the second spring 3018 will be contracted and extended in coordination with the movement of the moving plate 3015.

At this time, the fixed plate 3014 continues to move under the influence of the abutment rod 3012, and at the same time, the spring 2 3018 is in a contracted state, and the abutment plate 30112 also approaches the fixed block 3016. The abutment plate 30112 and one side of the fixed block 3016 form mutually fitting inclined surfaces. When the abutment plate 30112 and the inclined surface 30115 of the fixed block 3016 contact each other, the angle of the abutment plate 30112 will be caused to slide. At this time, the abutment plate 30112 will adjust the angle around the vertical pole 1 30111 as the center of the circle, and the rotation of the vertical pole 1 30111 will cause the torsion spring 30115 to stretch.

The transmission gear 2 3023 drives the transmission gear 3 3024 to rotate, and the transmission gear 3 3024 drives the vertical pole 3025 and the positioning plate 3026 to rotate, so that the positioning plate 3026 limits the nut that is pushed to the outside of the base 1011 immediately after the material is unloaded, thereby realizing the positioning of the two nuts between the templates 1012.Thus, the positioning plate 3026 cooperates with the tapped nut near the outside of the base 1011 for positioning, and the push rod 1014 contacts and limits the untapped nut. At this time, the tapping mechanism can be used to position the nut, increasing the stability and positioning accuracy in the nut tapping, which is different from the inconvenience of the existing push rod 1014 having an unlimited position structure after pushing the nut to the required range.
