Description

Technical Field

[0001] This utility model relates to a tap, specifically a double-headed spiral groove high-efficiency chip removal tap, belonging to the field of tap technology. Background Technology

[0002] A tap is a tool for machining internal threads. According to its shape, it can be divided into spiral flute taps, angled taps, straight flute taps, and pipe thread taps. According to the environment in which it is used, it can be divided into hand taps and machine taps. According to its specifications, it can be divided into metric, US, and imperial taps. Taps are the most mainstream machining tool used by operators in the manufacturing industry when tapping threads.

[0003] However, most existing taps have various problems. For example, in a tap disclosed in publication number CN104353914A, although a tap sleeve is set to assist and guide the tap during tapping, preventing the internal thread from being tapped crooked, reducing the difficulty of tapping, and improving the quality of tapping, in this technical solution and most taps at present, in order to improve efficiency, a double-ended spiral tap is sometimes used to perform dual-hole milling operations on the workpiece at the same time. However, in the technological development of double-ended spiral taps, the existing structure has the core problems of redundant drive mechanism and insufficient functional integration. Traditional double-ended taps require two sets of independent drive units, which increases the complexity of the equipment and makes synchronous control difficult. This discrete design not only occupies space, but also causes uneven load due to differences in power source characteristics, which affects the thread machining accuracy and may even cause the tap to break. In addition, the design of separating the angle adjustment mechanism from the drive system means that multiple systems need to work together when dynamically adjusting the cutting parameters, which increases mechanical transmission errors and maintenance costs. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a double-headed spiral groove high-efficiency chip removal tap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A double-headed spiral groove high-efficiency chip-removing tap includes a fixed base, a support base, a linkage milling mechanism, and an angle adjustment mechanism. The fixed base is fixed on an external machine tool, the support base is arranged side by side on one side of the fixed base, and the linkage milling mechanism and the angle adjustment mechanism are both arranged between the fixed base and the support base. The linkage milling mechanism includes a driving ball gear, a driven ball gear, a transmission rod, and a milling tap. The driving ball gear is rotatably connected to a fixed base, and the driven ball gear is rotatably connected to a support base. The driving ball gear and the driven ball gear are arranged side by side and mesh with each other. The two transmission rods are respectively fixed at the axis of the driving ball gear and the driven ball gear. The milling tap is coaxially fixed to one end of the transmission rod.

[0006] As a further embodiment of this utility model: the angle adjustment mechanism includes an active gear plate, a driven gear plate, and a docking plate. The active gear plate is rotatably connected to one end of the bottom of the fixed base, the driven gear plate is fixed to one end of the bottom of the support base, and the active gear plate and the driven gear plate mesh with each other. The docking plate is rotatably connected between the fixed base and the support base.

[0007] As a further embodiment of this utility model: the angle adjustment mechanism further includes a worm gear and a worm, the worm gear is located at the bottom of the worm wheel and is coaxially fixed with the drive gear plate, and the worm is rotatably connected to the bottom of the fixed seat and meshes with the worm gear.

[0008] As a further improvement of this utility model: a first servo motor is fixed to the other end of the bottom of the fixed base, and the output shaft of the first servo motor is fixed coaxially with the worm gear.

[0009] As a further improvement of this utility model: a second servo motor is fixed on one side of the top of the fixed base, and the output shaft of the second servo motor is coaxially fixed with the driving ball gear.

[0010] As a further improvement of this utility model: a mounting hole is provided at one end of the transmission rod near the milling tap, the milling tap is mated in the mounting hole, and is detachably connected to the transmission rod by screws provided on the outer wall of the transmission rod.

[0011] The beneficial effects of this utility model are: This invention incorporates a linkage milling mechanism and an angle adjustment mechanism, and replaces the traditional two independent drive units with a spherical gear meshing structure. This allows two milling taps to share a single power source, reducing equipment complexity and manufacturing costs. Furthermore, it ensures that even after changes in the angle between two adjacent transmission rods, the milling taps can still rotate synchronously. A self-locking structure is formed by a combination of worm gears and worm shafts, driving the active gear plate to engage with the driven gear plate, thereby driving the support seat to rotate and achieve angle adjustment. This breakthrough overcomes the technical bottlenecks of traditional double-ended taps in terms of mechanism integration and dynamic adjustment, providing an innovative solution for thread processing equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 4 As shown, a double-headed spiral groove high-efficiency chip removal tap includes a fixed base 1, a support base 2, a linkage milling mechanism 3, and an angle adjustment mechanism 4. The fixed base 1 is fixed on an external machine tool, the support base 2 is arranged side by side on one side of the fixed base 1, and the linkage milling mechanism 3 and the angle adjustment mechanism 4 are both arranged between the fixed base 1 and the support base 2. The linkage milling mechanism 3 includes a driving ball gear 31, a driven ball gear 32, a transmission rod 33, and a milling tap 34. The driving ball gear 31 is rotatably connected to the fixed base 1, and the driven ball gear 32 is rotatably connected to the support base 2. The driving ball gear 31 and the driven ball gear 32 are arranged side by side and mesh with each other. The two transmission rods 33 are respectively fixed at the axis of the driving ball gear 31 and the driven ball gear 32. The milling tap 34 is coaxially fixed to one end of the transmission rod 33. The angle adjustment mechanism 4 includes an active gear plate 41, a driven gear plate 42, and a docking plate 43. The active gear plate 41 is rotatably connected to one bottom end of the fixed base 1, and the driven gear plate 42 is fixed to one bottom end of the support base 2. The active gear plate 41 and the driven gear plate 42 mesh with each other, and the docking plate 43 is rotatably connected between the fixed base 1 and the support base 2. The angle adjustment mechanism 4 also includes a worm gear 44 and a worm 45. The worm gear 44 is located at the bottom of the worm gear 44 and is coaxially fixed with the drive gear 41. The worm 45 is rotatably connected to the bottom of the fixed seat 1 and meshes with the worm gear 44.

[0016] In this invention, by setting up a linkage milling mechanism 3 and an angle adjustment mechanism 4, and by using a spherical gear meshing structure to replace the traditional two independent drive units, the two milling taps 34 can share a single power source, reducing equipment complexity and manufacturing costs. At the same time, even after the angle between two adjacent transmission rods 33 changes, the milling taps 34 can still rotate synchronously. A self-locking structure is formed by the combination of worm gear 44 and worm 45, which drives the active gear plate 41 to drive the driven gear plate 42 to mesh and link, thereby driving the support 2 to rotate to achieve angle adjustment. This invention breaks through the technical bottleneck of traditional double-headed taps in terms of mechanism integration and dynamic adjustment, and provides an innovative solution for thread processing equipment. Example 2

[0017] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: The bottom of the fixed base 1 is fixed with a first servo motor 46. The output shaft of the first servo motor 46 is coaxially fixed with the worm gear 45. The first servo motor 46 drives the worm gear 45 to rotate, thereby driving the worm wheel 44 to quickly mesh and link, and driving the active gear plate 41 to rotate synchronously.

[0018] A second servo motor 47 is fixed on one side of the top of the fixed base 1. The output shaft of the second servo motor 47 is coaxially fixed with the active ball gear 31. The active ball gear 31 is driven to rotate by the second servo motor 47, which in turn drives the driven ball gear 32 to mesh and move together.

[0019] The transmission rod 33 has a mounting hole at one end near the milling tap 34. The milling tap 34 is mated in the mounting hole and is detachably connected to the transmission rod 33 by screws on the outer wall of the transmission rod 33, so that the milling tap 34 can be quickly disassembled and replaced.

[0020] Working principle: When using this tap, first connect and lock the milling tap 34 to the transmission rod 33. Then, drive the driving ball gear 31 to rotate through the second servo motor 47, which in turn drives the driven ball gear 32 to mesh and move together. At this time, the two milling taps 34 rotate synchronously to start milling the workpiece. If it is necessary to adjust the angle between the two milling taps 34 during milling, drive the worm gear 45 to rotate through the first servo motor 46, which in turn drives the worm wheel 44 to mesh and move together, and drives the driving gear 41 to rotate synchronously. At this time, the driven gear 42 meshes and moves the support 2 to rotate, so that the angle between the two milling taps 34 can be adjusted.

[0021] 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.
