Technical Field
[0001] This invention relates to the field of machining technology, and more specifically, to a handheld tapping device. Background Technology
[0002] In machining, tapping refers to using a certain torque to screw a tap into the hole to be drilled on the workpiece to produce an internal thread. A tapping machine is a machine tool that uses a tap to process internal threads and is widely used in tapping. Tapping machines are generally divided into bench tapping machines, semi-automatic bench tapping machines, vertical tapping machines, and horizontal tapping machines.
[0003] However, in current large-scale equipment manufacturing sites, there are a large number of threaded holes with a size of M16 or smaller, and the assembly structure of the workpieces to be tapped is complex, resulting in a lot of machining interference. For example, during the assembly and machining of large rolling mills, multiple fitters need to simultaneously perform final cleaning around a machine stand, and in some cases, work at height is required. In such cases, the aforementioned tapping machine is not suitable, and fitters need to manually tap the threads, for example, using angle bars. However, in this machining environment, manual tapping often lacks a point of force, making it difficult to control the tapping perpendicularity, and the tap is prone to breakage, resulting in poor safety. Moreover, the debris generated during machining cannot be cleaned up in a timely manner or is inconvenient to remove, making it difficult to guarantee machining accuracy. At the same time, there is also the problem of high manual labor intensity, which affects machining efficiency. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0030] To solve the above technical problems, such as Figure 1 and Figure 2 As shown, this embodiment of the invention provides a handheld tapping device, including an operation plate 1, a motor 2, a tap 3, a slide rod 4, a base plate 5, and a collection box 6. The slide rod 4 is vertically mounted on the base plate 5, and the operation plate 1 is sleeved on the slide rod 4. The motor 2 is driven by the tap 3, and the tap 3 is vertically mounted. The motor 2 is connected to the operation plate 1. The base plate 5 has a first hole 7 for the tap 3 to pass through. The collection box 6 is connected to the base plate 5, and the collection box 6 has an opening 8 facing the tap 3. The collection box 6 is used to collect the debris generated by the tap 3 during tapping through the opening 8.
[0031] Specifically, the motor 2 can be a planetary geared motor. The output shaft of the motor 2 is connected to the tap 3, driving the tap 3 to rotate. This is suitable for controlling the feed speed of the tap 3 during tapping, making the tapping operation more stable. Both the motor 2 and the tap 3 are vertically arranged and perpendicular to the operating plate 1 and the base plate 5, respectively, ensuring the perpendicularity of the tap 3 during tapping. The operating plate 1 can drive the motor 2 and the tap 3 to move vertically and pass through the first hole 7 until they abut against the bottom hole of the workpiece. The motor 2 can drive the tap 3 to rotate around its own axis to perform the tapping feed operation. The number of slide bars 4 can be one or more, without specific limitation. It should be noted that the opening 8 faces the tap 3 to facilitate the entry of debris carried out during the tap 3's rotation into the collection box 6. The collection box 6 has a collection cavity into which debris enters for storage. Alternatively, the collection box 6 can be designed as an openable box structure for easy removal of debris from the collection box 6 to a designated location after processing.
[0032] More specifically, both the operating plate 1 and the base plate 5 are plate structures and are arranged in parallel. For example, the operating plate 1 is a long strip, and the base plate 5 is a circular ring plate. The hollow part in the middle of the circular ring plate is the first hole 7. The structure of the circular ring plate makes it easier to fit and align with the workpiece surface. Multiple sliding rods 4 are spaced apart on the base plate 5. This structure is more stable and makes it easier to ensure the perpendicularity of the tap 3 during tapping, which can further improve the quality of the machining operation. At the same time, in order to further ensure the levelness of the operating plate 1 and the base plate 5, that is, to further ensure the perpendicularity of the tap 3 during tapping, a level can be installed on the operating plate 1. The operator can adjust the angle and position of the operating plate 1 by observing the level, which makes it easier and more accurate to ensure the perpendicularity of the tap 3 during tapping, further improving the quality of the machining operation.
[0033] In this embodiment, by vertically setting the slide bar 4 on the base plate 5 and sleeve the operating plate 1 on the slide bar 4, the operating plate 1 can move vertically towards the base plate 5 along the slide bar 4. By connecting the motor 2 to the operating plate 1 and driving the vertically set tap 3, the operating plate 1 drives the motor 2 and tap 3 to move vertically towards the base plate 5. When the motor 2 drives the tap 3 to perform tapping, it ensures that the feed direction of the tap 3 is along the direction of the vertically set slide bar 4, thus ensuring the verticality of the tapping process. Furthermore, by setting a collection box 6 on the base plate 5 and opening an opening towards the tap 3 in the collection box 6, the debris generated during the tapping process can enter the collection box 6 through the opening 8. With the above structural design, during use, the operator can hold the operating plate 1 and press it down, with the base plate 5 pressed tightly against the workpiece surface. The first hole 7 on the base plate 5 is aligned with the bottom hole to be machined on the workpiece, facilitating machining alignment and improving machining accuracy. Furthermore, the sliding rod 4 restricts and guides the movement direction of the operating plate 1, ensuring the perpendicularity of the tap 3's feed machining, further improving machining accuracy. At the same time, the motor 2 drives the tap 3 for tapping, replacing manual force application via tools such as angle bars, reducing labor intensity, facilitating operation, and improving work efficiency. Additionally, the collection box 6 collects debris, enabling simultaneous tapping and debris cleaning, ensuring machining quality while further improving tapping efficiency.
[0034] Optionally, such as Figure 1 and Figure 2As shown, the handheld tapping device further includes a mounting base 9, a pressure plate 10, a pull rod 11, an elastic telescopic assembly, and a transmission assembly. The mounting base 9 is disposed on the motor 2, and the tap 3 is rotatably connected to the mounting base 9. The pressure plate 10 is located between the operating plate 1 and the base plate 5. The two ends of the elastic telescopic assembly are respectively connected to the base plate 5 and the pressure plate 10. The two ends of the pull rod 11 are respectively hinged to the pressure plate 10 and the transmission assembly, and the pull rod 11 is inclined. The transmission assembly is drivenly connected to the collection box 6, and the collection box 6 is rotatably connected in the first hole 7. When the tap 3 taps, the mounting base 9 is used to abut against the pressure plate 10, and the pull rod 11 is used to drive the transmission assembly to drive the collection box 6 to rotate around the tap 3.
[0035] Specifically, the elastic telescopic component can be a component comprising a spring, for example, such as... Figure 2 The elastic telescopic component consists of an inner rod 21 sleeved inside an outer tube 22, which abuts against a first spring 23 located inside the outer tube 22. Therefore, when the pressure plate 10 is pressed down and the tap 3 retracts during tapping, that is, when the tap 3 faces... Figure 2 When the plate moves upward, the first spring 23 exerts an upward elastic force on the pressure plate 10 through the inner rod 21, allowing the pressure plate 10 to return to its original position. Furthermore, the transmission assembly can be a component that drives the collection box 6 to rotate via linear motion; for example, such as... Figure 2 As shown, the transmission assembly includes a gear 13 and a rack 14. The rack 14 moves linearly, driving the gear 13 to rotate, which in turn drives the collection box 6 connected to the gear 13 to rotate. Of course, the specific composition of the elastic telescopic assembly and the transmission assembly described above is merely an example to more clearly illustrate the working principle. Their specific structures are not specifically limited here and can be other types. For example, the elastic telescopic assembly can be a spring or an elastic component, or a component capable of linear reciprocating motion, such as a hydraulic cylinder. The transmission assembly can also be other types, such as consisting of a rope and a pulley, with the rope connected to the pulley 11, driving the pulley to rotate via the rope. Similarly, the specific structure of the mounting base 9 is not specifically limited here. It can be, for example, a circular tube structure, as long as it can abut against the pressure plate 10, forcing the pressure plate 10 to move downwards, and also serve as an auxiliary mounting point for the tap 3 and the output shaft of the motor 2.
[0036] More specifically, the pressure plate 10 is a circular plate structure with a circular hole in its middle for the tap 3 to pass through. The diameter of the circular hole is smaller than the outline size of the mounting base 9, so as not to hinder the tap 3 from tapping. It can also abut against the mounting base 9 when it moves downward.
[0037] In this embodiment, by setting the mounting base 9, on the one hand, it can assist the installation stability between the tap 3 and the motor 2, protect the tap 3, and make it more vertical. On the other hand, when the motor 2 and the tap 3 are feeding downwards for tapping, the mounting base 9 can abut against the pressure plate 10, so that they move downwards together. Then, the pull rod 11 is set at an angle, with its two ends hinged to the pressure plate 10 and the transmission assembly, respectively. As the pressure plate 10 moves downwards, the tilt angle of the pull rod 11 also changes, thereby driving the transmission assembly to move linearly. The transmission assembly is connected to the collection box 6 through the transmission assembly. The collection box 6 is rotatably connected in the first hole 7, so that when the tap 3 is feeding, the transmission assembly drives the collection box 6 to rotate around the tap 3. This allows the collection box 6 to collect debris around the tap 3 during the tapping process, making the debris cleaning effect cleaner and more thorough, further improving the operation quality of tapping and saving the operation time for cleaning debris. Meanwhile, by setting an elastic telescopic component between the pressure plate 10 and the base plate 5, on the one hand, the elastic telescopic component serves as a support structure for the pressure plate 10, making the overall structure more stable and robust. On the other hand, when tapping, the elastic telescopic component can provide upward elastic feedback to the pressure plate 10, making the downward movement of the pressure plate 10 more stable, thereby making the overall operation more stable. Moreover, when the tap 3 retracts and moves upward, the elastic telescopic component can spring the pressure plate 10 back to its original position. The structure is reasonable, the design is ingenious, it is easy to operate, and the operation is more time-saving and labor-saving.
[0038] Optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, the handheld tapping device also includes a mounting plate 12 disposed on the base plate 5. The transmission assembly includes a gear 13 and a rack 14. The rack 14 is slidably connected to the mounting plate 12. The mounting plate 12 has a stepped hole 15. The gear 13 is engaged with the stepped hole 15. The rack 14 is hinged to the pull rod 11, and the rack 14 is meshed with the gear 13. The collection box 6 is connected to the lower end face of the gear 13.
[0039] Specifically, the stepped hole 15 is a circular hole opened on the mounting plate 12, and a stepped structure is processed on the wall of the circular hole. The gear 13 is engaged in the stepped hole, that is, the lower end edge of the gear 13 abuts against the stepped surface of the stepped structure for support, preventing the gear 13 from falling off, while not hindering the rotation of the gear.
[0040] In this embodiment, by setting the mounting plate 12 on the base plate 5, the transmission component and the collection box 6 can be provided with installation positions and structures. By setting the transmission component to a structure in which the gear 13 and the rack 14 mesh, the structure operates more stably. The stepped hole 15 not only supports the gear 13 but also does not hinder its rotation. At the same time, by hinged to the rack 14, when the pressure plate 10 presses down and moves, causing the angle of the pull rod 11 to decrease, the pull rod drives the rack 14 to move linearly, thereby driving the gear 13 to rotate, which in turn drives the collection box 6 to rotate. This allows for better debris collection, and the structure is stable, operates smoothly, and saves time and effort.
[0041] Optionally, such as Figure 2 , Figure 3 and Figure 6 As shown, the collection box 6 includes an inner tube 16, an outer tube 17, an upper cover 18, and a lower cover 19. The inner tube 16 is disposed inside the outer tube 17, and the inner tube 16, the outer tube 17, and the tap 3 are coaxially arranged. The upper cover 18 is connected to the upper ends of the inner tube 16 and the outer tube 17, and the upper cover 18 is connected to the gear 13. The lower cover 19 is snapped into the lower ends of the inner tube 16 and the outer tube 17. The opening 8 is opened in the inner tube 16. The opening 8 is an elongated hole structure. The length direction of the opening 8 is arranged along the axial direction of the inner tube 16, and the long side of the opening 8 extends towards the tap 3 and is provided with a retaining edge 20.
[0042] Specifically, the inner tube 16 and the outer tube 17 have the same length, the diameter of the outer tube 17 is larger than the diameter of the inner tube 16, and the shape and structure of the upper cover 18 and the lower cover 19 are adapted to the two annular end faces of the cylindrical collection cavity formed by the inner tube 16 and the outer tube 17. That is, the tap 3 can be vertical during the tapping process and is coaxial with the inner tube 16, passing through the middle of the inner tube 16. The upper cover 18 and the lower cover 19 will not hinder the movement of the tap 3. The structure is more reasonable.
[0043] In this embodiment, the inner tube 16, outer tube 17, upper cover 18, and lower cover 19 together form the cavity for collecting debris in the collection box 6, allowing the tap 3 to pass through and rotate coaxially around the tap 3. By snapping the lower cover 19 to the lower ends of the inner tube 16 and outer tube 17, the lower cover 19 can be easily removed to discharge the debris from the collection box 6, making it more reasonable and convenient to use. Furthermore, by providing a retaining edge 20 extending from the long side of the opening 8 toward the tap 3, the retaining edge 20 can be closer to the tap 3. That is, during the tapping process, the retaining edge 20 rotates around the tap 3 and scrapes off the debris generated on it, which then enters the collection box 6, making the debris cleaning more thorough and clean, and further improving the quality of operation.
[0044] Optionally, such as Figure 1 and Figure 2 As shown, the elastic telescopic assembly includes an inner rod 21, an outer tube 22, and a first spring 23. The outer tube 22 is vertically mounted on the mounting plate 12, and the first spring 23 is disposed inside the outer tube 22. The inner rod 21 is sleeved with the outer tube 22, and the first spring 23 abuts against one end of the inner rod 21. The other end of the inner rod 21 is connected to the pressure plate 10.
[0045] Specifically, the bottom end of the outer tube 22 is fixedly connected to the mounting plate 12, and the other end is sleeved with the inner rod 21. One end of the inner rod 21 is sleeved inside the outer tube 22, and the other end is fixedly connected to the lower end face of the pressure plate 10. The first spring 23 is coaxially arranged with both the outer tube 22 and the inner rod 21. The first spring 23 is vertically arranged inside the outer tube 22 and is adapted to the internal space dimensions of the outer tube 22 to ensure the verticality of the first spring 23 when compressed, thereby ensuring the stability of the elastic telescopic component.
[0046] In this embodiment, the elastic telescopic component is configured as a structure consisting of an inner rod 21, an outer tube 22, and a first spring 23. The structure is simple, easy to implement, and saves costs. The pressure plate 10 can be moved downward more stably by the elastic force of the first spring 23 and can be reset to its original position. Furthermore, the verticality of the first spring 23 is limited by the outer tube 22, making the structure more stable.
[0047] Optionally, such as Figure 2 and Figure 5 As shown, the mounting plate 12 has a sliding groove 24 that matches the rack 14. The rack 14 is slidably connected in the sliding groove 24. The number of racks 14, the number of elastic telescopic components, and the number of pull rods 11 are all two, and the two racks 14, the two elastic telescopic components, and the two pull rods 11 are respectively arranged opposite to each other.
[0048] Specifically, the two racks 14 are meshed and connected to the opposite sides of the gear 13, and the tie rod 11 is hinged to the end of the rack 14, which can meet the motion stroke while saving installation space.
[0049] In this embodiment, by providing a groove 24 on the mounting plate 12, the rack 14 can be limited, and the rack 14 can be provided with smoother and more precise linear movement, thereby making the overall operation more stable and accurate. At the same time, by having two racks 14, two elastic telescopic components, and two pull rods 11, and by setting them relative to each other, the overall structure is more stable and robust, and the operation is smoother and more stable.
[0050] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the handheld tapping device also includes a second spring 25, which is sleeved on the slide rod 4, and the two ends of the second spring 25 abut against the operating plate 1 and the base plate 5 respectively.
[0051] In this embodiment, by attaching a second spring 25 to the slide bar 4, with its two ends abutting against the operating plate 1 and the base plate 5 respectively, the second spring 25 can provide a certain elastic feedback to the operating plate 1 during the tapping process, which is performed by moving the motor 2 and the tap downwards by holding the operating plate 1. This makes the downward movement of the motor 2 and the tap 3 by the operating plate 1 smoother, preventing uneven downward pressure from causing tapping defects and further improving the processing quality. At the same time, when the tap 3 needs to be moved upwards to retract, the second spring 25 can also provide a certain rebound force, which is more time-saving and labor-saving.
[0052] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the handheld tapping device also includes a cover plate 26, which is connected to the end of the slide rod 4 away from the base plate 5, and the cover plate 26 has a second hole for the motor 2 to pass through.
[0053] Specifically, the lower end of the slide rod 4 is fixedly connected to the base plate 5, and the upper end of the slide rod 4 is fixedly connected to the cover plate 26, forming a stable overall frame structure. Furthermore, the second hole and the first hole, as well as the holes opened on the pressure plate 10 and the mounting plate 12, are all concentrically set to maximize the perpendicularity of the tap 3 machining.
[0054] In this embodiment, by connecting the cover plate 26 to the end of the slide bar 4 away from the base plate 5, a stable frame structure is formed, preventing the operating plate 1 from sliding off the slide bar 4 and disengaging the connection, thus ensuring the stability and robustness of the overall structure. Furthermore, by providing a second hole on the cover plate 26, on the one hand, the downward movement of the motor 2 is not hindered, and on the other hand, the second hole can also provide a certain radial support to the motor 2, preventing it from shaking excessively, further improving the stability of the overall structure.
[0055] Optionally, such as Figure 1 and Figure 4 As shown, the operation plate 1 has gripping holes 27 at its opposite ends. The motor 2 is vertically connected to the operation plate 1 at the position between the two gripping holes 27. A button 28 is provided on the operation plate 1 near the gripping holes 27. The button 28 is electrically connected to the motor 2.
[0056] Specifically, the shape of the holding hole 27 can be designed according to ergonomics, and the number of buttons 28 can be multiple. For example, multiple buttons 28 can be set to control the forward rotation of the motor 2, control the reverse rotation of the motor 2, control the stop, etc. There is no specific limitation here.
[0057] In this embodiment, by providing a gripping hole 27 on the operation panel 1 and vertically connecting the motor 2 to the position between the two gripping holes 27, it is easier for the operator to grip the operation panel 1 for processing and to lift and move the whole unit.
