Description

Technical Field

[0001] This utility model relates to a folding arm tapping machine, and more particularly to a multi-station folding arm tapping machine, belonging to the related technical field of folding arm tapping machines. Background Technology

[0002] A folding arm tapping machine, also known as a rocker arm tapping machine or a universal tapping machine, is an automated or semi-automated device specifically designed for processing internal threads. Its core advantage lies in its foldable and rotatable folding arm structure, which allows for flexible tapping of workpieces in different positions and with different specifications. It is widely used in machinery manufacturing, automotive parts, hardware processing, and other fields. The folding arm tapping machine is a special tapping device developed from traditional tapping machines, such as vertical tapping machines and benchtop tapping machines. Its core feature is that it has a folding arm frame that can be adjusted at multiple angles, which, together with the spindle unit, enables tapping operations in non-fixed positions.

[0003] However, during operation, a single-station folding arm tapping machine typically operates on a one-to-one basis. The working logic of a single-station folding arm tapping machine is a single cycle of loading, tapping, and unloading, and it can only process one workpiece at a time. In practice, multiple stations are arranged irregularly or linearly, with a single worker operating one station. However, this arrangement requires reserving transport space for the folding arm tapping machine before and after each station. In addition, with multiple stations, this arrangement will occupy a significant amount of space when factory space is limited. Furthermore, this method also results in a longer and more cumbersome workpiece transport distance, which is not conducive to tapping large batches of workpieces or maintaining the folding arm tapping machine.

[0004] Therefore, it is urgent to improve the multi-station articulated arm tapping machine to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-station folding arm tapping machine to solve the problem of the inconvenience of using single-station folding arm tapping machines.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a fixed base, a lifting base located above the fixed base, and several folding arm tapping machine bodies disposed on the lifting base. The lifting base moves longitudinally along the fixed base via a lifting assembly. Several extension tracks are arranged around the axis of the lifting base. Mounting bases suitable for mounting the folding arm tapping machine bodies are slidably connected to the extension tracks. A drive mechanism for driving the mounting bases to move along the extension direction of the extension tracks is provided on the extension tracks.

[0007] Preferably, the lifting assembly includes a sleeve longitudinally connected to a fixed base and a lifting column longitudinally connected to the bottom of the lifting base. One end of the lifting column extends into the interior of the sleeve and is axially slidably connected to the sleeve. A bearing base is connected to the inner side wall of the sleeve near the fixed base. A longitudinal threaded rod is rotatably connected to the bearing base along the axial direction of the sleeve. A threaded hole suitable for threaded connection of the longitudinal threaded rod is opened on the lifting column along its axial direction.

[0008] Preferably, the lifting assembly further includes a rotary motor, a drive shaft, and a transmission gear assembly. The rotary motor is mounted on a fixed base, the end of the drive shaft is connected to the output end of the rotary motor, and the transmission gear assembly consists of two meshing bevel gears, which are respectively connected to the longitudinal threaded rod and the end of the drive shaft.

[0009] Preferably, the lifting base has a plurality of radial grooves suitable for installation on the extension track, the extension track has a sliding groove, the mounting base is slidably connected to the sliding groove, the mounting base has a longitudinal through-hole mounting groove, the mounting groove is provided with a stabilizing shaft, and the main body of the folding arm tapping machine is mounted on the stabilizing shaft.

[0010] Preferably, the drive mechanism includes a rotating base mounted on the bottom of the extension track, a radial threaded rod rotatably connected to the rotating base, a threaded block connected to the bottom of the mounting base, and a drive motor mounted on the rotating base; wherein, one end of the radial threaded rod passes through the rotating base and is connected to the output end of the drive motor, and the threaded block is threadedly connected to the radial threaded rod.

[0011] Preferably, sliding blocks are connected to both side walls at the bottom of the mounting base, and a sliding rod is connected to the bottom of the extension track, with the sliding blocks slidably connected to the sliding rod.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-5 As shown, the multi-station folding arm tapping machine provided in this embodiment includes a fixed base 1, a lifting base 2 located above the fixed base 1, and several folding arm tapping machine bodies 3 disposed on the lifting base 2, as follows: Figure 1 As shown, the main body 3 of the folding arm tapping machine is a common device for processing internal threaded holes. It has a handle and a motor at its end, and a pre-installed drill bit is connected to the end of the motor. When using the main body 3 of the folding arm tapping machine, the worker can hold the end of the main body 3 and move the position of the end of the folding arm tapping machine 3 freely under the action of the mechanical arm. A switch for controlling the motor is set on the handle for easy operation by the worker. The specific details are not described in detail.

[0024] To improve workpiece processing efficiency and worker convenience, a lifting base 2 is longitudinally moved along a fixed base 1 via a lifting assembly. Several extension rails 4 are arranged around the axis of the lifting base 2. Mounting bases 5, suitable for mounting the folding arm tapping machine body 3, are slidably connected to the extension rails 4. It should be noted that, depending on the number and size of the workstations, at least one folding arm tapping machine body 3 can be aligned with a single workstation. In this case, at least two folding arm tapping machine bodies 3 can be mounted close together on adjacent mounting bases 5. If several folding arm tapping machine bodies 3 need to be equidistantly arranged, they should be evenly distributed on the mounting bases 5 of the extension rails 4. There is no limitation on this arrangement. The extension rails 4 are equipped with driving mechanisms. The drive mechanism that moves the mounting base 5 along the extension direction of the extension track 4 is used. When in use, a workstation is set at the corresponding position on the outside of the device. When it is necessary to process and tap the workpiece, the workpiece is placed on the workstation table. The worker can hold the output end of the folding arm tapping machine body 3 to tap the workpiece. Since several folding arm tapping machine bodies 3 are installed on the lifting base 2, one worker can operate at least one folding arm tapping machine body 3 to tap the workpiece. Moreover, the lifting base 2 has a circular structure, and the workstations are set around the lifting base 2. Compared with the irregular or linear arrangement of workstations, this method occupies less space and can accommodate more workstations in the same space. Secondly, it also reduces the time for transferring workpieces between different workstations and increases the workpiece conveying efficiency.

[0025] It should be noted that the main application scenarios for this device are to handle large batches of round workpieces or workpieces with circumferentially distributed threaded holes, such as flanges, gears, valves, and motor end caps, especially those requiring multi-process integration, such as tapping, inspection, and deburring. Based on existing mature control technology, a controller can be installed on this device to facilitate workers in opening, closing, and controlling the electrical equipment such as the main body 3 of the folding arm tapping machine, the drive mechanism, and the lifting components.

[0026] Among them, such as Figure 1 as well as Figure 3As shown, in order to facilitate the adaptation of the lifting base 2 to the workstation height and the use of the main body 3 of the folding arm tapping machine, the lifting assembly mentioned above includes a sleeve 6 longitudinally connected to the fixed base 1 and a lifting column 7 longitudinally connected to the bottom of the lifting base 2. One end of the lifting column 7 extends into the interior of the sleeve 6 and is axially slidably connected to the sleeve 6. A bearing base 8 is connected to the inner wall of the end of the sleeve 6 near the fixed base 1. A longitudinal threaded rod 9 is rotatably connected to the bearing base 8 along the axial direction of the sleeve 6. A threaded hole suitable for threaded connection of the longitudinal threaded rod 9 is opened on the lifting column 7 along its axial direction. When the longitudinal threaded rod 9 is rotated, the longitudinal threaded rod 9 will rotate in the threaded hole. Then, through the screwing action between the longitudinal threaded rod 9 and the threaded hole, the lifting column 7 is moved. Depending on the rotation direction of the longitudinal threaded rod 9, the lifting column 7 can be moved up or down, and finally the lifting base 2 can be moved up or down.

[0027] The lifting assembly described above also includes a rotary motor 10, a drive shaft 11, and a transmission gear assembly 12. The rotary motor 10 is mounted on the fixed base 1. The end of the drive shaft 11 is connected to the output end of the rotary motor 10. The rotary motor 10 drives the drive shaft 11 to rotate, which in turn drives the longitudinal threaded rod 9 to rotate within the sleeve 6 via the rotating gear assembly. The transmission gear assembly 12 consists of two meshing bevel gears 13. The two bevel gears 13 are respectively connected to the ends of the longitudinal threaded rod 9 and the drive shaft 11. The rotary motor 10 outputs torque, which drives the drive shaft 11 to rotate. The rotating drive shaft 11 drives the bevel gear 13 connected to it to rotate, which in turn drives the other bevel gear 13 to rotate, which in turn drives the longitudinal threaded rod 9 to rotate within the sleeve 6. When the longitudinal threaded rod 9 rotates, it drives the lifting column 7 to slide along the axial direction of the sleeve 6. When the lifting column 7 slides upward, it drives the lifting base 2 to move upward, thus adapting to work surfaces of different heights.

[0028] Furthermore, such as Figure 1 as well as Figure 4As shown, when a workstation is set up in the outer area of ​​the lifting base 2, if the gap between the workstation and the lifting base 2 is large, the robotic arm on the main body 3 of the folding arm tapping machine needs to extend a long distance before its output end can be driven by the worker. This will reduce the flexibility of the main body 3 of the folding arm tapping machine. Therefore, to facilitate the movement and installation of the main body 3 of the folding arm tapping machine, several radial grooves 14 suitable for the installation of extension rails 4 are radially opened on the lifting base 2. The extension rails 4 are connected in the radial grooves 14, which can be connected by bolts or welding, without limitation. Furthermore, the number of radial grooves 14 is not less than the number of extension rails 4, so that several folding arm tapping machine bodies 3 can be connected together. The flexible installation allows for the installation of the extension track 4, which has a sliding groove 15. The mounting base 5 is slidably connected to the sliding groove 15. The mounting base 5 has a longitudinally penetrating mounting groove 16, and a stabilizing shaft 17 is installed in the mounting groove 16. The main body 3 of the folding arm tapping machine is mounted on the stabilizing shaft 17. At this time, the mounting base 5 can be driven to move along the extension track 4 through the drive mechanism, which can move the main body 3 of the folding arm tapping machine radially closer to the work station, increasing the usable range of the output end of the main body 3 of the folding arm tapping machine. Furthermore, the stabilizing shaft 17 and the mounting base 5 can be connected by bolts, and the mounting end of the main body 3 of the folding arm tapping machine can also be connected to the stabilizing shaft 17 by bolts, which facilitates subsequent disassembly and maintenance.

[0029] like Figure 4 As shown, the drive mechanism includes a rotating base 18 mounted on the bottom of the extension track 4, a radial threaded rod 19 rotatably connected to the rotating base 18, a threaded block 21 connected to the bottom of the mounting base 5, and a drive motor 20 mounted on the rotating base 18. One end of the radial threaded rod 19 passes through the rotating base 18 and is connected to the output end of the drive motor 20. The threaded block 21 is threadedly connected to the radial threaded rod 19. When the drive motor 20 is started, it drives the radial threaded rod 19 to rotate, which in turn drives the threaded block 21 to move, which in turn drives the mounting base 5 connected to the threaded block 21 to move. Finally, it can move the main body 3 of the folding arm tapping machine. Depending on the rotation direction of the radial threaded rod 19, the main body 3 of the folding arm tapping machine can be moved away from or closer to the work position.

[0030] To ensure greater stability when the radial threaded rod 19 drives the mounting base 5 to move linearly, sliding blocks 22 are connected to both side walls at the bottom of the mounting base 5, and a sliding rod 23 is connected to the bottom of the extension track 4. The sliding blocks 22 are slidably connected to the sliding rod 23. When the mounting base 5 moves, the sliding blocks 22 slide on the sliding rod 23. The sliding rod 23 guides and supports the sliding of the mounting base 5, preventing the mounting base 5 from getting stuck when sliding in the sliding groove 15. Furthermore, before using this device, the contact surfaces between the mounting base 5 and the sliding groove 15, and the contact surfaces between the sliding rod 23 and the sliding blocks 22, need to be lubricated.

[0031] like Figure 2 As shown, in order to facilitate the storage and organization of the main body 3 of the folding arm tapping machine and improve the aesthetics of the workstation, a protective cover 24 is provided on the lifting base 2. The protective cover 24 has several through holes 25 suitable for the main body 3 of the folding arm tapping machine to pass through. After the drive mechanism drives the main body 3 of the folding arm tapping machine to be retracted into the protective cover 24 through the mounting base 5, the protective cover 24 can reduce the impact of external debris on the main body 3 of the folding arm tapping machine and form protection for the main body 3 of the folding arm tapping machine.
