Description

Technical Field

[0001] This utility model relates to the field of metal processing chip technology, specifically to a spiral groove tap device with multi-segment arc-shaped groove features. Background Technology

[0002] In the field of metal processing, internal threads are a key structure for connecting and fixing components and are widely used in industries such as machinery manufacturing, automotive parts, and aerospace devices. As the core tool for machining internal threads, the performance of taps directly determines the thread machining accuracy, surface quality, and production efficiency. In order to optimize the performance of taps, multiple helical grooves are usually opened on the outside of the tap to enable the tap to remove chips more smoothly during the tapping process.

[0003] During tapping operations, especially under high-speed rotation conditions, the waste generated by the tap cutting often carries a high temperature and splashes everywhere at extremely high speeds. This upward-splashing high-temperature waste has a strong impact force and is dangerous. Without effective protection, it can easily come into direct contact with the operator. This splashing waste may scratch the operator's hands, arms and other exposed skin, and in more serious cases, it may splash onto the face and eyes, causing scratches, burns or even more serious eye damage, posing a direct and serious threat to the operator's personal safety. Therefore, those skilled in the art provide a spiral groove tap device with multi-segment arc-shaped groove features to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a spiral groove tap device with multi-segment arc-shaped grooves, which solves the problem in the prior art that upward-splashing waste may accidentally injure workers during tapping operations.

[0005] This utility model provides the following technical solution: a spiral groove tap device with multi-segment arc-shaped groove features, including an installation section, a transition section and a tapping section, wherein the transition section is provided with a protective component for blocking splashed waste, and the transition section is provided with an elastic connecting component for elastically supporting the protective component.

[0006] As a preferred embodiment of the above technical solution, the transition section includes a housing, a sliding rod is slidably sleeved at one end of the housing near the installation section, a connecting plate is fixedly connected to one end of the sliding rod near the installation section, the connecting plate is fixedly connected to the installation section, and two first limiting grooves are formed on the inner wall of the housing, a first limiting block is slidably sleeved inside each of the two first limiting grooves, and both first limiting blocks are fixedly connected to the sliding rod.

[0007] As a preferred embodiment of the above technical solution, the tapping section includes a tapping rod, which is fixedly connected to the end of the housing away from the mounting section. The tapping rod has tapping threads on its outer side and spiral grooves arranged in an array on its outer side.

[0008] As a preferred embodiment of the above technical solution, the protective component includes a trapezoidal connecting block, which is fixedly connected to a sliding rod. A sliding groove is provided on the outer side of the trapezoidal connecting block, and a through-hole is provided on the outer shell. A protective plate is slidably fitted inside the through-hole, and a sliding block is fixedly connected to the side of the protective plate near the trapezoidal connecting block. The sliding block is slidably fitted inside the sliding groove.

[0009] As a preferred embodiment of the above technical solution, a groove is provided on the side of the protective plate near the installation section, and a fixing block is slidably fitted inside the groove, and the fixing block is fixedly installed on the inner wall of the opening.

[0010] As a preferred embodiment of the above technical solution, the elastic connection assembly includes a support rod, and the trapezoidal connecting block has an inner groove on the side near the tapping rod. The support rod is slidably sleeved inside the inner groove, and a spring located inside the inner groove is fixedly connected to the end of the support rod away from the tapping rod. A second limiting groove is provided on the outer side of the inner groove, and a second limiting block is slidably sleeved inside the second limiting groove. The second limiting block is fixedly connected to the support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This spiral groove tap device, featuring multi-segment arc-shaped grooves, causes the mounting section to press downwards during tapping. This causes the sliding rod fixed on the mounting section to slide downwards, which in turn drives the trapezoidal connecting block to slide inside the outer casing. The relative movement between the trapezoidal connecting block and the outer casing causes the trapezoidal connecting block to push the protective plate to slide, allowing the protective plate to extend outwards along the opening. When tapping, the protective plate rotates at high speed, forming a protective barrier around the tap. This causes the flying iron filings to hit the protective plate and fall down, preventing waste from flying upwards and providing safety for the operator. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-5 As shown, this utility model provides a technical solution: a spiral groove tap device with multi-segment arc-shaped groove features, including an installation section 1, a transition section 2 and a tapping section 3. The transition section 2 is provided with a protective component 4 for blocking splashed waste material, and the transition section 2 is provided with an elastic connecting component 5 for elastically supporting the protective component 4.

[0016] When using this device for tapping, the end of the tapping section 3 will first come into contact with the material. As the installation section 1 and the transition section 2 move downward, the protective component 4 will be pushed out. During the tapping operation, the high-speed rotation of the device will block the waste material that splashes upward from the protective component 4, thereby achieving a protective function.

[0017] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the transition section 2 includes a housing 21. A sliding rod 22 is slidably sleeved on one end of the housing 21 near the installation section 1. A connecting plate 23 is fixedly connected to one end of the sliding rod 22 near the installation section 1. The connecting plate 23 is fixedly connected to the installation section 1. Two first limiting grooves 24 are opened on the inner wall of the housing 21. A first limiting block 25 is slidably sleeved inside each of the two first limiting grooves 24. Both first limiting blocks 25 are fixedly connected to the sliding rod 22.

[0018] When the tapping section 3 contacts the workpiece and begins cutting, the axial force applied by the machine tool spindle causes the tapping section 3 to move the outer shell 21 toward the mounting section 1. At this time, the outer shell 21 slides axially along the sliding rod 22. The sliding rod 22 is kept relatively fixed to the mounting section 1 through the connecting plate 23. During the sliding process of the outer shell 21, the sliding of the first limiting block 25 inside the first limiting groove 24 limits and guides the outer shell 21 and the sliding rod 22 to avoid deviation and make the device more stable.

[0019] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the tapping section 3 includes a tapping rod 31, which is fixedly connected to the end of the housing 21 away from the mounting section 1. The tapping rod 31 has tapping teeth 32 on its outer side and spiral grooves 33 arranged in an array on its outer side.

[0020] As the tapping section 3 rotates and embeds itself into the material, the material is threaded through the setting of the tapping teeth 32. The centrifugal force and axial feed force of the rotating tap are used to transport the chips upward along the spiral groove 33, thereby achieving rapid separation of the chips from the machined surface.

[0021] For one implementation method described in this embodiment, please refer to [link / reference]. Figures 1-4 As shown, the protective component 4 includes a trapezoidal connecting block 41, which is fixedly connected to the sliding rod 22. A sliding groove 42 is provided on the outer side of the trapezoidal connecting block 41. A through-hole 43 is provided on the outer shell 21. A protective plate 44 is slidably fitted inside the through-hole 43. A sliding block 45 is fixedly connected to the side of the protective plate 44 near the trapezoidal connecting block 41. The sliding block 45 is slidably fitted inside the sliding groove 42. A sliding groove 46 is provided on the side of the protective plate 44 near the installation section 1. A fixing block 47 is slidably fitted inside the sliding groove 46. The fixing block 47 is fixedly installed on the inner wall of the through-hole 43.

[0022] When the tap begins tapping, the tapping section 3 is pushed by the axial force to move the outer shell 21 toward the mounting section 1. Since the sliding rod 22 is stationary relative to the outer shell 21, the trapezoidal connecting block 41 and the outer shell 21 have an axial relative displacement. As the trapezoidal connecting block 41 slides, when the sliding block 45 slides along the inclined trajectory of the sliding groove 42, the axial displacement is converted into radial thrust, which pushes the protective plate 44 to extend outward along the opening 43 of the outer shell 21. When machining the threaded hole, the iron filings generated by the high-speed rotation hit the protective plate 44 and fall down, preventing the waste from splashing upward. When the protective plate 44 slides, the fixed block 47 slides inside the sliding groove 46 to guide and limit the protective plate 44, preventing the protective plate 44 from getting stuck due to uneven force, and preventing the protective plate 44 from slipping, making the device more stable.

[0023] As one implementation method in this embodiment, please refer to Figures 1-5As shown, the elastic connection assembly 5 includes a support rod 51, a trapezoidal connecting block 41 with an inner groove 52 on the side near the tapping rod 31, the support rod 51 is slidably sleeved inside the inner groove 52, a spring 53 located inside the inner groove 52 is fixedly connected to the end of the support rod 51 away from the tapping rod 31, a second limiting groove 54 is provided on the outer side of the inner groove 52, a second limiting block 55 is slidably sleeved inside the second limiting groove 54, and the second limiting block 55 is fixedly connected to the support rod 51.

[0024] When tapping is completed, the elastic thrust applied to the trapezoidal connecting block 41 by the spring 53 pushes the sliding rod 22 to slide away from the tapping section 3, so that it automatically resets. At the same time, during the sliding of the sliding rod 22, the sliding block 45 slides inside the sliding groove 42, so that the two protective plates 44 slide towards each other and are hidden in the through opening 43, ensuring that the protective plates 44 are flush with the outer shell 21. The sliding of the second limiting block 55 inside the second limiting groove 54 limits the sliding of the support rod 51 inside the inner groove 52, preventing the support rod 51 from slipping off.

[0025] Working principle: Before the device is started, the outer shell 21 is stably sleeved on the outside of the sliding rod 22 through the cooperation of the first limiting block 25 and the first limiting groove 24. The sliding rod 22 is relatively fixed to the installation section 1 by means of the connecting plate 23. The protective plate 44 of the protective component 4 is retracted inside the opening 43 of the outer shell 21. The sliding block 45 is located at the initial end of the sliding groove 42 of the trapezoidal connecting block 41. At the same time, the spring 53 of the elastic connecting component 5 is in a natural extension and contraction state. Under the limitation of the second limiting block 55 and the second limiting groove 54, the support rod 51 is stably fitted into the inner groove 52 of the trapezoidal connecting block 41. When the drive device starts tapping, the end of the tapping rod 31 of the tapping section 3 first contacts the material to be processed. The axial force applied by the machine tool spindle pushes the tapping section 3 and drives the housing 21 to move towards the mounting section 1. At this time, since the sliding rod 22 remains stationary due to being fixed to the mounting section 1, the housing 21 slides axially along the sliding rod 22. The sliding of the first limiting block 25 in the first limiting groove 24 provides guidance and limitation for the movement of the housing 21, preventing the housing 21 from deviating and ensuring the stability of the device operation. As the outer shell 21 and the sliding rod 22 generate relative displacement, the protective component 4 starts to activate. The trapezoidal connecting block 41 remains stationary with the sliding rod 22, forming an axial relative movement with the outer shell 21. The sliding block 45 slides along the inclined trajectory of the sliding groove 42 of the trapezoidal connecting block 41, converting the axial displacement into radial thrust, pushing the protective plate 44 to extend outward along the opening 43. During this process, the sliding groove 46 on the protective plate 44 slides and engages with the fixing block 47 on the inner wall of the opening 43, which not only prevents the protective plate 44 from being stuck due to uneven force, but also prevents it from slipping off, ensuring that the protective plate 44 unfolds stably and forms a waste blocking barrier. Simultaneously, the tapping rod 31 of the tapping section 3 rotates at high speed under the drive of the spindle, and the tapping teeth 32 perform thread processing on the material. The generated chips are conveyed upward along the spiral grooves 33 arrayed on the outer side of the tapping rod 31 under the combined action of the centrifugal force of the rotating tap and the axial feed force, realizing the rapid separation of chips from the machined surface. When the chips splash upward, the deployed protective plate 44 blocks them, causing the chips to fall after impacting the protective plate 44, effectively preventing waste from splashing and causing damage to operators or equipment. When the tapping operation is completed, the machine tool spindle stops applying axial force, and the spring 53 in the inner groove 52 releases elastic potential energy, applying elastic thrust to the trapezoidal connecting block 41, pushing the sliding rod 22 to slide away from the tapping section 3, causing the connecting plate 23 to move synchronously with the mounting section 1, so that the outer shell 21 gradually returns to its initial position. During the reset process of the sliding rod 22, the relative displacement between the trapezoidal connecting block 41 and the outer shell 21 is reversed, and the sliding block 45 slides in the opposite direction along the sliding groove 42, pulling the protective plate 44 to retract inward along the through-hole 43 until the protective plate 44 is hidden in the through-hole 43 and flush with the surface of the outer shell 21. At the same time, the second limiting block 55 of the elastic connecting component 5 slides in the second limiting groove 54, limiting the reset movement of the support rod 51, preventing the support rod 51 from slipping out of the inner groove 52, and finally returning the entire device to its initial state, preparing for the next tapping operation.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
