Description

Technical Field

[0001] This utility model relates to a threaded tap, specifically an adjustable diameter modular threaded tap, belonging to the field of threaded tap technology. Background Technology

[0002] A threaded insert tap, also known as an ST tap, is a tool specifically designed for machining internal threads when installing wire threaded inserts. Its core function is to cut a special pilot hole thread in the base material to fit the wire threaded insert. The threaded hole produced by the threaded insert tap differs from that of a standard tap. The diameter of the threaded insert tap is larger than that of a standard tap of the same specification, leaving room for the wire threaded insert to be assembled. The machining accuracy directly affects the thread quality after the wire threaded insert is installed, and it is necessary to ensure that the pilot hole thread and the external thread of the insert are precisely matched.

[0003] However, most existing thread insert taps have various problems. For example, in the integrated tapping and guiding thread insert tap disclosed in announcement number CN218903883U, although the tap body, composed of a tap shank, a tapping section, and a chip guide groove, has both guiding and tapping functions, it can meet the requirement of guiding and tapping the thread insert without changing the tap, thus enhancing the continuity of thread insert processing and improving the efficiency of tap processing of thread inserts. However, in this technical solution and most current thread insert taps, the existing technology generally adopts a multi-taper synchronous milling process to improve efficiency. However, due to the diversity of workpiece materials and structural differences, the tap spacing must be dynamically adapted. Currently, most taps adopt a fixed spacing design, resulting in poor processing adaptability. Even if some equipment can be adjusted, it still relies on manual disassembly and assembly, such as replacing shims or the entire fixture. Each adjustment takes a lot of time and significantly drags down production efficiency. 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 an adjustable diameter modular threaded tap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable diameter modular threaded tap includes a support base, a driving rod, a limiting groove, a locking block, a driven rod, a threaded tap body, and a transmission adjustment mechanism. The driving rod is rotatably connected to the support base. The limiting groove is disposed through the support base and has an arc-shaped structure. The locking block is slidably engaged in the limiting groove. The driven rod is rotatably connected to the locking block. The two threaded tap bodies are respectively connected to one end of the driving rod and the driven rod.

[0007] The transmission adjustment mechanism is mounted on the support base and includes an adjustment plate, a support rod, a linkage plate, and a lead screw. The adjustment plate is rotatably connected to the driven rod, the support rod is rotatably connected to one side of the support base, the linkage plate is rotatably connected to the support rod, and a through hole is provided through the linkage plate. One end of the lead screw is rotatably connected to the adjustment plate, and the other end passes through the through hole.

[0008] As a further embodiment of this utility model: a nut is rotatably connected to one side of the linkage plate, the nut is coaxially arranged with the through hole, and the lead screw is threadedly engaged with the nut.

[0009] As a further embodiment of this utility model: the transmission adjustment mechanism further includes a driving gear, a driven gear, and a drive gear. The driving gear is coaxially fixed on the driving rod, the driven gear is coaxially fixed on the driven rod, and the drive gear is rotatably connected in the support base. The driving gear and the driven gear are staggered and both mesh with the drive gear.

[0010] As a further embodiment of this utility model: one end of both the driving rod and the driven rod is coaxially fixed with a mating sleeve, and the screw tap body is connected inside the mating sleeve. The screw tap body is detachably connected to the mating sleeve by screws.

[0011] As a further improvement of this utility model, the screw thread tap body is provided in various models, and the diameters of the various models of screw thread tap bodies are all different.

[0012] As a further improvement of this utility model: the top of the support base is provided with a sliding groove, the sliding groove has an arc-shaped structure and is connected to the limiting groove, and a positioning rod is fixed on the locking block, the positioning rod being slidably engaged in the sliding groove.

[0013] The beneficial effects of this utility model are:

[0014] In this utility model, a transmission adjustment mechanism is set up, which drives the active gear and the driven gear to rotate synchronously through the drive gear, and drives the active rod and the driven rod to rotate synchronously. When it is necessary to adjust the distance between two adjacent threaded tap bodies, the screw thread is linked by rotating the nut, and then the driven rod drives the locking block to slide in the limiting groove, thereby realizing the rapid adjustment of the distance between two adjacent threaded tap bodies. It is simple, efficient and practical, and effectively solves the problem that current taps cannot dynamically adapt to the distance requirements between different workpieces, significantly improving production efficiency.

[0020] 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

[0021] like Figures 1 to 4 As shown, an adjustable diameter modular threaded tap includes a support base 1, a driving rod 2, a limiting groove 3, a locking block 4, a driven rod 5, a threaded tap body 6, and a transmission adjustment mechanism 7. The driving rod 2 is rotatably connected to the support base 1. The limiting groove 3 is provided through the support base 1 and has an arc-shaped structure. The locking block 4 is slidably engaged in the limiting groove 3. The driven rod 5 is rotatably connected to the locking block 4. The two threaded tap bodies 6 are respectively connected to one end of the driving rod 2 and the driven rod 5.

[0022] The transmission adjustment mechanism 7 is mounted on the support base 1, and includes an adjustment plate 71, a support rod 72, a linkage plate 73, and a lead screw 74. The adjustment plate 71 is rotatably connected to the driven rod 5, the support rod 72 is rotatably connected to one side of the support base 1, the linkage plate 73 is rotatably connected to the support rod 72, and a through hole is provided through the linkage plate 73. One end of the lead screw 74 is rotatably connected to the adjustment plate 71, and the other end passes through the through hole. A nut 75 is rotatably connected to one side of the linkage plate 73. The nut 75 is coaxially arranged with the through hole, and the lead screw 74 and the nut 75 are threadedly engaged.

[0023] The transmission adjustment mechanism 7 also includes a drive gear 76, a driven gear 77 and a driving gear 78. The drive gear 76 is coaxially fixed on the drive rod 2, the driven gear 77 is coaxially fixed on the driven rod 5, and the driving gear 78 is rotatably connected in the support base 1. The drive gear 76 and the driven gear 77 are staggered and both mesh with the driving gear 78.

[0024] In this utility model, by setting a transmission adjustment mechanism 7, the drive gear 78 synchronously drives the driving gear 76 and the driven gear 77 to rotate synchronously, and drives the driving rod 2 and the driven rod 5 to rotate synchronously. When it is necessary to adjust the distance between two adjacent threaded tap bodies 6, the screw 74 is threadedly linked by rotating the nut 75, and then the driven rod 5 drives the locking block 4 to slide in the limiting groove 3, thereby realizing the rapid adjustment of the distance between two adjacent threaded tap bodies 6. It is simple, efficient and practical, and effectively solves the problem that current taps cannot dynamically adapt to the distance requirements between different workpieces, significantly improving production efficiency. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] Both the driving rod 2 and the driven rod 5 have a mating sleeve 8 fixed coaxially at one end. The threaded tap body 6 is connected inside the mating sleeve 8. The threaded tap body 6 is detachably connected to the mating sleeve 8 by screws, which allows the threaded tap body 6 to be quickly disassembled and assembled.

[0027] The threaded tap body 6 is available in various models, and the diameters of the various models of threaded tap body 6 are different. By setting up various models of threaded tap body 6, the threaded tap can meet the milling requirements of different workpieces.

[0028] The top of the support base 1 is provided with a sliding groove 9. The sliding groove 9 has an arc-shaped structure and is connected to the limiting groove 3. A positioning rod 10 is fixed on the locking block 4. The positioning rod 10 is slidably engaged in the sliding groove 9. The positioning rod 10 further improves the stability of the locking block 4.

[0029] Working principle: When using this threaded tap, first insert the threaded tap body 6 into the mating sleeve 8 and lock it with screws. Then, drive the driving gear 78 to drive the driving gear 76 and driven gear 77 to rotate, which in turn drives the driving rod 2, driven rod 5 and threaded tap body 6 to rotate synchronously and perform milling operations on the workpiece. When it is necessary to adjust the distance between two adjacent threaded tap bodies 6, rotate the nut 75 to make the screw 74 threadedly linked, and drive the driven rod 5 to move through the adjusting plate 71, so that the locking block 4 slides in the locking block 4 until the distance between the two adjacent threaded tap bodies 6 is adjusted to an appropriate distance.
