Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically a tapping machine with tapping head switching. Background Technology

[0002] A tapping machine is a mechanical device used to process threads on workpieces. It typically creates threaded holes in the material by rotating a cutting tool. Widely used in machinery manufacturing, automotive, and aerospace industries, it can efficiently and accurately process threads of various specifications. Tapping machines can be categorized into manual, semi-automatic, and fully automatic types based on their level of automation, and are characterized by ease of operation, high processing accuracy, and high production efficiency.

[0003] Different sizes of threaded holes require different types of tapping heads for processing. Therefore, when using a traditional tapping machine to process different threaded holes, it is necessary to replace the tapping head, remove the tapping head, and then reinstall the required type of tapping head. The disassembly and assembly process is time-consuming, labor-intensive, and inefficient. In addition, the tapping head is usually fastened with screws, and the disassembly and assembly of screws further increases the complexity of the operation. Utility Model Content

[0004] The purpose of this invention is to provide a tapping machine with tapping head switching, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A tapping machine with tapping head switching includes a mounting base. A drive rod is rotatably mounted on the bottom of the mounting base, and a bearing seat is mounted on the side of the mounting base. A shaft is rotatably mounted vertically through the bearing seat, and a rotating disk is fixed at the bottom of the shaft. Multiple tapping heads are rotatably mounted in a circular array around the axis of the rotating disk. Each tapping head has a different model. A first drive mechanism for driving the drive rod to rotate is provided on the top of the mounting base, and a second drive mechanism for driving the shaft to rotate is provided on the side of the mounting base, so as to realize the rotation switching of the tapping heads. A drive component is provided at the bottom end of the drive rod, and a transmission component is provided at the top end of each tapping head. The drive component and the transmission component cooperate accordingly to drive the corresponding tapping head to rotate for tapping when the drive rod rotates.

[0007] Therefore, by arranging different types of tapping heads on the rotating disk, when machining different threaded holes, it is only necessary to rotate and adjust the rotating disk to switch the required type of tapping head to the working position. There is no need to disassemble and replace the tapping heads, which saves time and effort and is highly efficient.

[0008] Furthermore, the driving component uses a driving gear, and each transmission component uses a driven gear. The driving gear can mesh with each driven gear.

[0009] Furthermore, during one rotation cycle of the shaft, the drive gear can sequentially mesh with each driven gear.

[0010] Furthermore, the first drive mechanism includes a first mounting bracket and a first drive device. The first mounting bracket is fixed to the top of the mounting base, and the first drive device is mounted on the first mounting bracket. The first drive device is used to drive the drive rod to rotate.

[0011] Furthermore, the first drive device uses a servo motor, which is fixed on the first mounting bracket. The drive rod extends through to the top of the mounting base and is fixedly connected to the output shaft of the servo motor.

[0012] Furthermore, the second drive mechanism includes a second mounting bracket, a worm, a second drive device, and a worm wheel. The second mounting bracket is fixed to the rear side of the mounting base, the worm is rotatably mounted on the second mounting bracket, the second drive device is mounted on the rear side of the second mounting bracket and is used to drive the worm to rotate and adjust, and a worm wheel is fixed to the top of the shaft and meshes with the worm.

[0013] Furthermore, the second drive device uses a stepper motor, which is fixedly mounted on the rear side of the second mounting bracket, and its output shaft is fixedly connected to one end of the worm gear.

[0014] Furthermore, the shaft and the rotating disk are arranged coaxially.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention arranges different types of tapping heads on a rotating disk. When machining different threaded holes, simply rotate the rotating disk to adjust the tapping head of the required type to the working position. There is no need to disassemble or replace the tapping head, which saves time and effort and is highly efficient.

[0017] When the required tapping head is switched to the working position, the present invention utilizes the meshing of the drive gear and the driven gear to achieve the transmission effect. Thus, when the first drive mechanism drives the drive rod to rotate, it can drive the tapping head in the working position to rotate, so that different models of tapping heads can share a common drive source after switching, thereby reducing equipment cost investment.

[0018] This invention utilizes the unidirectional transmission effect of worm gear and worm wheel to achieve a self-locking function. After the required tapping head is adjusted to the working position, it helps maintain the position of the tapping head when not adjusted, preventing the shaft from rotating randomly and causing the driven gear and drive gear to misalign and lose the transmission effect, thus effectively ensuring the stability during tapping.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-4This utility model provides a tapping machine with tapping head switching, including a mounting base 1, a drive rod 2 rotatably mounted on the bottom of the mounting base 1, a bearing seat 11 mounted on the side of the mounting base 1, a shaft 3 rotatably mounted vertically through the bearing seat 11, a rotating disk 4 fixed at the bottom of the shaft 3, the shaft 3 and the rotating disk 4 are arranged coaxially, and multiple tapping heads 5 are rotatably mounted in a ring array around the axis of the rotating disk 4, each tapping head 5 having a different model.

[0028] The top of the mounting base 1 is provided with a first drive mechanism 6 for driving the drive rod 2 to rotate, and the side of the mounting base 1 is provided with a second drive mechanism 7 for driving the shaft rod 3 to rotate, so as to realize the rotation switching of the tapping head 5. The bottom end of the drive rod 2 is provided with a drive component 21, and the top end of each tapping head 5 is provided with a transmission component 51. The drive component 21 and each transmission component 51 cooperate accordingly to drive the corresponding tapping head 5 to rotate for tapping when the drive rod 2 rotates.

[0029] The drive component 21 uses a drive gear, and each transmission component 51 uses a driven gear. The drive gear can mesh with each driven gear, and in one rotation cycle of the shaft 3, the drive gear can mesh with each driven gear in turn, ensuring that when each tapping head 5 switches to the working position, the driven gear on it can mesh with the drive gear.

[0030] The second drive mechanism 7 works to drive the shaft 3 and the rotating disk 4 to adjust the rotation, thereby switching the tapping head 5. During the rotation adjustment of the rotating disk 4, the rotation adjustment can be canceled when the driven gear at the top of the required tapping head 5 meshes with the drive gear. Then, the first drive mechanism 6 works to drive the drive rod 2 and the drive gear to rotate. The drive gear meshes with the driven gear and drives the required tapping head 5 to rotate, thus performing tapping.

[0031] This tapping machine arranges different types of tapping heads 5 on a rotating disk 4. When machining different threaded holes, it is only necessary to rotate and adjust the rotating disk 4 to switch the required type of tapping head 5 to the working position. There is no need to disassemble or replace the tapping head 5, which saves time and effort and is highly efficient.

[0032] When the required tapping head 5 is switched to the working position, the meshing of the drive gear and the driven gear is used to realize the transmission action. Then, when the first drive mechanism 6 drives the drive rod 2 to rotate, the tapping head 5 in the working position can be driven to rotate, so that different models of tapping heads 5 can share a common drive source after switching, reducing equipment cost investment.

[0033] Specifically, the first drive mechanism 6 includes a first mounting bracket 61 and a first drive device 62. The first mounting bracket 61 is fixed to the top of the mounting base 1, and the first drive device 62 is mounted on the first mounting bracket 61. The first drive device 62 is used to drive the drive rod 2 to rotate.

[0034] The first drive device 62 uses a servo motor, which is fixed on the first mounting bracket 61. The drive rod 2 extends through to the top of the mounting base 1 and is fixedly connected to the output shaft of the servo motor.

[0035] The servo motor operates, and its output shaft drives the drive rod 2 to rotate, thereby providing drive for the tapping head 5 to rotate and tap. In addition, the servo motor as the first drive device 62 has high position and speed control accuracy, ensuring the accuracy of the tapping process. It has a fast response speed and can quickly adjust the speed and torque when needed to adapt to different processing requirements. It can provide high torque at low speeds, making it suitable for tapping operations that require large cutting forces.

[0036] Specifically, the second drive mechanism 7 includes a second mounting bracket 71, a worm 72, a second drive device 73, and a worm wheel 74. The second mounting bracket 71 is fixed to the rear side of the mounting base 1. The worm 72 is rotatably mounted on the second mounting bracket 71. The second drive device 73 is mounted on the rear side of the second mounting bracket 71 and is used to drive the worm 72 to rotate and adjust. The top end of the shaft 3 is fixed with a worm wheel 74, which meshes with the worm 72.

[0037] The second drive device 73 uses a stepper motor, which is fixedly installed on the rear side of the second mounting bracket 71, and its output shaft is fixedly connected to one end of the worm gear 72.

[0038] The stepper motor operates, and its output shaft drives the worm gear 72 to rotate. The rotating worm gear 72 meshes with and drives the worm wheel 74, which in turn drives the shaft 3 and the rotating disk 4 to rotate, providing drive for the rotation switching of the tapping head 5. In addition, the stepper motor can precisely control the rotation angle and position, ensuring that the tapping head 5 can accurately switch to the required position, improving the machining accuracy and reliability. The stepper motor is controlled by pulse signals and can be easily integrated with the CNC system to realize the automated switching of the tapping head 5 and improve production efficiency.

[0039] By utilizing the unidirectional transmission effect of the worm 72 and worm wheel 74, a self-locking function can be achieved. After the required tapping head 5 is adjusted to the working position, it helps to maintain the position of the tapping head 5 when not adjusted, preventing the shaft 3 from rotating arbitrarily and causing the driven gear and drive gear to misalign and lose the transmission effect, thus effectively ensuring the stability during tapping.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
