Description

Technical Field

[0001] This utility model relates to the field of tapping guides, and in particular to a tapered guide head for an anti-jamming thread tapping guide. Background Technology

[0002] In machining, tapping is one of the important processes for making internal threads. The cutting tools used to machine internal threads have grooves along the axial direction. According to the thread shape, they are divided into straight flute taps, spiral flute taps, and spiral point taps. Straight flute taps are easy to machine, with slightly lower precision, but higher output. They are generally used for thread machining on ordinary lathes, drilling machines, and tapping machines, and the cutting speed is relatively slow. Spiral flute taps are mostly used for drilling blind holes in CNC machining centers. They have a faster machining speed, higher precision, better chip removal, and better centering. Spiral taps have a chip relief groove at the front and are used for machining through holes. Trapezoidal thread taps often use an unequal diameter design.

[0003] In existing thread tapping processes, when machining deep-hole threads using tapping tools, a drill bit is needed to drill the hole, and then the tapping head is used to tap simultaneously. This process can lead to chip removal and a rapid increase in drill bit temperature, resulting in high resistance and a high risk of drill bit jamming. Consequently, the drill bit's hardness decreases due to its inability to withstand high temperatures, which in turn affects the drilling quality and efficiency, and in severe cases, can even damage and render the drill bit unusable. To address these issues, a tapered guide head for preventing jamming in thread tapping is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tapered guide head for an anti-jamming thread tapping guide, which aims to improve the problem in the prior art that "high resistance leads to rapid temperature rise, causing drill bit jamming, and the drill bit's hardness decreases due to its inability to withstand high temperatures".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tapered guide head for an anti-jamming thread tapping guide, comprising a main body, a tapered head fixedly connected to the bottom of the main body, a spiral drilling edge provided on the surface of the tapered head, a handle fixedly connected to the top of the main body, an oil inlet provided on the top of the handle, a reservoir provided inside the tapered head, an oil passage provided inside the main body, the reservoir communicating with the oil inlet through the oil passage, multiple channels provided inside the tapered head, the multiple channels being arranged in annular and equidistant intervals inside the tapered head, an annular groove provided on the surface of the tapered head, an outlet provided on the surface of the tapered head, and the reservoir communicating with the outlet through the channels.

When the tapping machine drives the tapered head to rotate and rubs against the workpiece, it can reduce frictional resistance, reduce heat accumulation, and prevent the tap from overheating and deforming. Thus, it provides continuous lubrication throughout the tapping process, reduces friction and heat accumulation, and improves tapping quality and efficiency.

[0028] 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.

[0029] Reference Figure 1 - Figure 3 One embodiment of this utility model is a tapered guide head for an anti-jamming thread tapping guide, comprising a main body 1. The surface of the main body 1 is provided with a tapping blade 2 for cutting threads, and a chip removal groove 3 for helping to remove iron filings generated during the cutting process to avoid clogging and jamming. A tapered head 4 is fixedly connected to the bottom of the main body 1 to facilitate guiding and cutting into the workpiece. The tapered head 4 gradually expands the workpiece opening through a tapered angle design to reduce initial resistance and prevent tool jamming. The surface of the tapered head 4 is provided with a spiral drilling blade 5.

[0030] Reference Figure 1 , Figure 2 The top of the main body 1 is fixedly connected to a handle 6. The surface of the handle 6 is provided with a square plane 7 for easy fixing or rotation using tools such as wrenches. The surface of the handle 6 is provided with a mounting groove 8. The main body 1, the conical head 4 and the handle 6 are all integrally forged. The surface of the main body 1 is provided with a connecting sleeve 9 for reinforcing the overall structure and ensuring a tight connection between the components. The connecting sleeve 9 is provided with a screw 10 inside.

[0031] Reference Figure 1 , Figure 3The top of the handle 6 is provided with an oil inlet 11 for injecting lubricating oil. The oil inlet 11 delivers lubricant to the outlet 15 through the reservoir 12, oil passage 13 and channel 14 to form a continuous lubricating film, reduce friction and temperature rise, and reduce the risk of jamming. The conical head 4 is provided with a reservoir 12 inside, and the main body 1 is provided with an oil passage 13 inside. The reservoir 12 is connected to the oil inlet 11 through the oil passage 13. The conical head 4 is provided with a channel 14 inside to deliver the lubricating oil in the reservoir 12 to the outlet 15. The number of channels 14 is set to multiple, and the multiple channels 14 are arranged in a ring at equal angles inside the conical head 4. The surface of the conical head 4 is provided with an annular groove 16. The annular groove 16 helps to further enhance the lubrication effect and also assists in chip removal. The surface of the conical head 4 is provided with an outlet 15. The outlet 15 is evenly distributed in the tapping area to reduce friction and cool the workpiece. The reservoir 12 is connected to the outlet 15 through the channel 14.

[0032] Working principle: When in use, the taper is first fixedly installed on the tapping machine through the mounting slot 8 on the handle 6. When the tapping machine is working, the main body 1 rotates, which drives the tapered head 4 to rotate. The tapered head 4 easily cuts into the workpiece with the spiral drilling edge 5 on its surface. Then the tapping edge 2 on the surface of the main body 1 goes deep into the workpiece. The tapping edge 2 rotates to cut threads in the inner hole of the workpiece. At the same time, the chip removal groove 3 removes the iron chips generated during the cutting process to prevent clogging and tool jamming.

[0033] Before installation, lubricating oil can be injected through the oil inlet 11. The lubricating oil flows into the reservoir 12 through the oil passage 13 and is evenly distributed to multiple outlets 15 on the surface of the tapered head 4 through the channel 14. Coolant or lubricating oil can be directly introduced into the tapping area. When the tapping machine rotates the tapered head 4 and rubs against the workpiece, it can reduce frictional resistance, reduce heat accumulation, and prevent the tap from overheating and deforming. This provides continuous lubrication throughout the tapping process, reduces friction and heat accumulation, and improves tapping quality and efficiency.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
