Description

Technical Field

[0001] This application relates to the field of thread raceway quenching technology, and in particular to a thread raceway quenching equipment and processing system. Background Technology

[0002] In the field of mechanical manufacturing, threaded raceways are a key structure in core transmission components such as ball screws and trapezoidal screws. Their surface hardness, wear resistance, and fatigue strength directly affect the transmission accuracy and service life of the equipment. Currently, the commonly used quenching process for threaded raceways employs induction heating technology. This involves generating an alternating magnetic field through an induction coil to induce eddy currents on the raceway surface, thus achieving rapid quenching. However, traditional induction hardening equipment suffers from several problems in practical applications: Firstly, the connection structure between the induction coil and the power supply is complex, making installation and maintenance inconvenient, and prone to uneven heating due to poor contact. Secondly, the layout and fixing methods of the induction coil in existing equipment cannot guarantee a uniform magnetic field distribution, resulting in poor consistency in the quenching depth and hardness of the threaded raceway, especially when processing high-precision, complex-shaped threaded raceways, making it difficult to meet process requirements. Furthermore, the heat dissipation and airflow design of traditional equipment is insufficient, easily causing localized overheating, reducing coil lifespan, and increasing production costs.

[0044] The following reference Figures 1 to 4 This application describes a thread raceway quenching equipment and processing system according to some embodiments.

[0045] See Figures 1 to 3 As shown, an embodiment of the first aspect of this application provides a thread raceway quenching device, which includes a heating assembly. The heating assembly includes a placement guide ring 11 and a heating part. The heating part includes a placement ring 121 and an induction coil 124. The placement guide ring 11 includes a first polar ring 111, a second polar ring 112, and an insulating ring 113 coaxially arranged. The first polar ring 111 and the second polar ring 112 are respectively fixed to both sides of the insulating ring 113. The placement ring 121 includes a first polar seat 1211, a second polar seat 1212, and a connector 122. The first polar seat 1211 and the second polar seat 1212 are connected via the connector 122 to form a placement ring 121 clamped to the placement guide ring 11. The first polarity seat 1211 is attached to the outside of the first polarity ring 111, the second polarity seat 1212 is attached to the outside of the second polarity ring 112, the heating part is disposed inside the guide ring 11, one end of the induction coil 124 is fixed to the first polarity seat 1211, and the other end of the induction coil 124 is fixed to the second polarity seat 1212.

[0046] According to the thread raceway quenching equipment provided by the above technical features, on the one hand, by designing the guide ring 11 as a coaxial arrangement of a first polar ring 111, a second polar ring 112, and an insulating ring 113, and cooperating with the mounting ring 121 composed of a first polar seat 1211, a second polar seat 1212, and a connector 122, a modular assembly structure is formed. This effectively simplifies the connection method between the induction coil 124 and the power supply. During installation, only the polar seat needs to be attached to the polar ring to complete the electrical connection, significantly reducing the assembly complexity. At the same time, the modular design allows for quick disassembly and replacement of faulty parts during equipment maintenance, greatly improving the maintainability and flexibility of the equipment. On the other hand, the two ends of the induction coil 124 are fixed to the first polar seat 1211 and the second polar seat 1212 respectively. This symmetrical layout allows the alternating magnetic field generated by the induction coil 124 to act uniformly on the surface of the thread raceway. The placement of the guide ring 11 optimizes the guidance of the magnetic field, effectively avoiding the problem of uneven magnetic field distribution in traditional equipment that causes differences in quenching depth and hardness. This ensures that the thread raceway surface obtains a consistent hardened layer depth and hardness, significantly improving quenching quality and the overall performance of the parts.

[0047] Preferably, such as Figures 1 to 4 As shown, the aforementioned connector 122 can be a fastener, such as a bolt or screw, connecting the first polarity seat 1211 and the second polarity seat 1212, to facilitate the detachment of the mounting ring 121. Preferably, as... Figures 1 to 4 As shown in the figure, an example of the above-mentioned mounting ring 121 being provided with four of the above-mentioned connectors 122 is presented to ensure the stability of the mounting ring 121.

[0048] Preferably, such as Figures 1 to 4 As shown, the outer edge of the aforementioned mounting ring 121 is cubic in shape, which not only facilitates the processing and manufacturing of the mounting ring 121, but also facilitates the tight fixing of the aforementioned connector 122.

[0049] Preferably, such as Figures 2 to 4 As shown, the aforementioned mounting ring 121 may also be covered with an insulating pad 1213, which may be disposed between the first polarity seat 1211 and the second polarity seat 1212 to ensure the insulation between the first polarity seat 1211 and the second polarity seat 1212.

[0050] Preferably, the cross-sectional shape of the aforementioned placement guide ring 11 can be circular. Correspondingly, the shape of the inner edge of the placement ring 121 formed by the aforementioned placement ring 121 can be adapted to the shape of the cross-sectional shape of the aforementioned placement guide ring 11. In this way, on the one hand, good contact between the first polarity seat 1211 and the first polarity ring 111, and between the second polarity seat 1212 and the second polarity ring 112 is ensured; on the other hand, the included angle of the induction coil 124 relative to the placement guide ring 11 can be finely adjusted within a certain range by the placement ring 121, effectively improving the setting accuracy of the position of the induction coil 124 relative to the workpiece 3, thereby ensuring the processing accuracy of the quenching process.

[0051] It should be noted that, with Figures 1 to 3 Taking the orientation shown as an example, the angle between the induction coil 124 and the placement guide ring 11 can be understood as the angle between the axial direction of the induction coil 124 and the central plane of the placement guide ring 11; in other words, adjusting the angle between the induction coil 124 and the placement guide ring 11 can be understood as adjusting the degree to which the end of the induction coil 124 away from the placement ring 121 is offset upward (or downward) relative to the placement guide ring 11.

[0052] Optionally, the workpiece 3 to be processed can be a trapezoidal screw, ball screw, ordinary triangular thread screw, multi-start screw, or other workpiece with threaded raceways.

[0053] Preferably, such as Figures 1 to 4 As shown, the first polarity seat 1211 may also be provided with a first through hole that passes through itself in the radial direction of the placement guide ring 11. One end of the induction coil 124 can be inserted into the first polarity seat 1211 through the first through hole, so as to realize the fixed connection between the first polarity seat 1211 and one end of the induction coil 124.

[0054] Similarly, such as Figures 1 to 4 As shown, the second polarity seat 1212 may also be provided with a second through hole that passes through itself in the radial direction of the placement guide ring 11. The other end of the induction coil 124 can be inserted into the second polarity seat 1212 through the second through hole to achieve a fixed connection between the second polarity seat 1212 and the other end of the induction coil 124.

[0055] Preferably, such as Figures 2 to 4 As shown, the first polarity seat 1211 may be provided with an internal threaded hole that passes through itself. The aforementioned mounting ring 121 may also include an anti-rotation pin 123, which can be screwed into the internal threaded hole and abut against the mounting guide ring 11, so that the mounting ring 121 is fixed relative to the mounting guide ring 11 through the abutment action of the anti-rotation pin 123 and the first polarity ring 111.

[0056] Optionally, the second polarity seat 1212 may also be provided with a through-hole internally threaded hole, and the aforementioned anti-rotation pin 123 may be screwed into the internally threaded hole to abut against the placement guide ring 11, so as to fix the placement ring 121 relative to the placement guide ring 11 through the abutment action of the anti-rotation pin 123 and the first polarity seat 1211. It should be noted that the aforementioned placement ring 121 may include two anti-rotation pins 123, and the two anti-rotation pins 123 may be screwed into the first polarity seat 1211 and the second polarity seat 1212 respectively. However, it is not limited to this, the aforementioned placement ring 121 may also include only one anti-rotation pin 123, which may be screwed into the internally threaded hole of either the first polarity seat 1211 or the second polarity seat 1212.

[0057] Preferably, such as Figures 1 to 4 As shown, the aforementioned induction coil 124 can be a spiral induction coil 124 extending radially along the placement of the guide ring 11. Thus, by adjusting the pitch of the spiral coil (such as a variable pitch design), the axial magnetic field intensity distribution can be precisely controlled to adapt to the differentiated heating requirements of different tooth profiles (such as trapezoidal and triangular) at the tooth tip, tooth side, and tooth root. This effectively increases the coupling area between the induction coil 124 and the thread raceway surface, improving the energy conversion rate. The rotating magnetic field generated by the spiral coil makes the eddy current distribution closer to the actual stress state of the thread, which can obtain a conformal hardened layer and significantly improve fatigue resistance. The spiral structure can freely expand and contract axially when heated, reducing the risk of coil cracking due to thermal stress concentration and extending the service life of the equipment.

[0058] Preferably, such as Figures 1 to 4 As shown, the heating part may also include a magnetically conductive part 125, which is disposed inside the induction coil 124. The high permeability of the magnetically conductive part 125 (usually made of ferrite or silicon steel sheet, etc.) concentrates the dispersed magnetic lines of force to the surface of the thread raceway, thereby improving the precise heating of the thread raceway surface, enhancing the magnetic field strength of the thread raceway surface, enhancing the induced eddy current density, and accelerating the heating speed.

[0059] Preferably, such as Figure 4 and Figure 5As shown, the magnetically conductive part 125 may include a magnetically conductive post 1251 and a magnetically conductive needle 1252. The magnetically conductive post 1251 may extend in the radial direction of the placement of the flow guide ring 11, and the magnetically conductive post 1251 is fixed inside the induction coil 124. The magnetic needle 1252 is fixed to the end face of the magnetic post 1251 opposite to the guide ring 11. At least a portion of the magnetic needle 1252 can extend into the thread raceway of the workpiece 3. Thus, the magnetic needle 1252, extending into the thread raceway, can effectively guide magnetic lines of force directly to key areas such as the tooth flank and tooth root, increasing the magnetic field strength in these areas. This effectively solves the problem of insufficient hardened layer at the tooth root in traditional quenching, increases the depth of the hardened layer at the tooth root, and ensures the quenching effect of the thread raceway. Furthermore, the combination of the magnetic post 1251 and the magnetic needle 1252 forms a "post-needle" magnetic field distribution, maintaining a moderate magnetic field strength in the tooth tip region (avoiding overheating) while strengthening the magnetic field on the tooth flank and tooth root, achieving uniform distribution of the hardened layer across the entire tooth surface. In addition, the shape of the magnetic needle 1252 can be customized according to the thread groove type (such as trapezoidal or arc-shaped) to match the raceway contour, achieving contour heating along the tooth profile, and ensuring that the hardened layer shape closely matches the thread stress state.

[0060] Preferably, such as Figure 5 As shown, a countersunk hole 1253 can also be provided at the end of the magnetic needle 1252 away from the magnetic post 1251. In this way, the structure of the countersunk hole 1253 can change the current distribution at the tip of the magnetic needle 1252, so that the magnetic field forms a "ring-shaped reinforcement zone" at the tooth root radius, eliminating the hardness trough commonly found at the tooth root radius in traditional quenching, and the hardened layer transitions continuously at the tooth root without soft band defects. The air layer inside the countersunk hole 1253 forms a heat insulation buffer, avoiding overheating caused by magnetic field concentration at the tooth root tip, reducing the temperature difference between the tooth root and the tooth surface, and making the surface stress distribution more uniform after quenching.

[0061] Preferably, such as Figures 1 to 4 As shown, the aforementioned induction coil 124 can be a flow guide tube; in other words, the induction coil 124 has a flow channel for the coolant to flow through. Figures 2 to 4 As shown, a spray hole 1241 can be provided on the side of the guide tube facing the magnetic part 125. In this way, the coolant can be guided to the location of the magnetic part 125 through the guide tube and sprayed onto the magnetic part 125 through the spray hole 1241, so as to achieve timely cooling of the magnetic part 125 and extend the service life of the magnetic part 125.

[0062] Preferably, such as Figures 1 to 4As shown, the aforementioned placement guide ring 11 may include a straight segment 102 and an arc segment 101, which are alternately connected to form the aforementioned placement guide ring 11. The aforementioned heating assembly may include multiple heating elements, and the aforementioned mounting ring 121 may be clamped onto the straight section 102. Thus, on the one hand, by placing the mounting ring 121 on the straight section 102, it is not only effective to facilitate the clamping of the mounting ring 121, ensuring good fit between the mounting ring 121 and the mounting guide ring 11, thereby ensuring the stability of the magnetic field; it also effectively facilitates the rotation of the mounting ring 121 relative to the mounting guide ring 11 within a certain range, thereby facilitating the fine adjustment of the angle between the induction coil 124 and the mounting guide ring 11. On the other hand, by providing multiple heating elements, each positioned on a corresponding straight section 102, if the workpiece 3 has multiple thread raceways, the multiple heating elements can achieve simultaneous quenching of multiple thread raceways; if the workpiece 3 has only one thread raceway, the multiple heating elements can achieve simultaneous quenching of multiple positions of the thread raceway, effectively improving quenching efficiency.

[0063] Optionally, the plurality of arc segments 101 can be arranged on a common circle, and the radial direction of the guide ring 11 can be understood as the radial direction of the circle in which the plurality of arc segments 101 are located.

[0064] like Figures 1 to 4 As shown in the figure, an example of the heating assembly comprising four sets of heating elements is illustrated. The four sets of heating elements can be evenly distributed along the circumferential direction of the guide ring 11 to ensure uniform force distribution on the heating assembly. However, this is not the only limitation. The number of heating elements included in the heating assembly can be adaptively adjusted according to actual needs. For example, the heating assembly can include one, two, three, five, six, or more heating elements.

[0065] In an embodiment, such as Figures 1 to 3 and Figure 6 As shown, the aforementioned thread raceway quenching equipment may further include a cooling assembly, which may include a spray ring 21, an inlet pipe 22, and an outlet pipe 23. The spray ring 21 can be fitted onto the outside of the workpiece 3 to be processed, and a liquid passage space is provided inside the spray ring 21. The inlet pipe 22 and the outlet pipe 23 are respectively connected to the liquid passage space. Furthermore, the inner wall of the spray ring 21 is evenly distributed with multiple spray holes 210. Thus, a portion of the cooling liquid can flow sequentially through the inlet pipe 22 and the liquid passage space from the spray holes 210 on the inner wall of the spray ring 21 and spray onto the workpiece 3 to cool the workpiece 3 heated by the heating assembly in a timely manner, thereby achieving the quenching effect. Another portion of the cooling liquid can flow sequentially through the inlet pipe 22, the liquid passage space, and the outlet pipe 23 to achieve cooling circulation of the cooling liquid within the cooling assembly, thereby ensuring the temperature stability of the cooling assembly and thus ensuring the cooling efficiency of the cooling assembly.

[0066] Preferably, such as Figure 1 As shown, when the thread raceway quenching equipment is in the processing state, the workpiece to be heated can be positioned along the direction of gravity. Correspondingly, the cooling component can be positioned below the heating component to prevent coolant dripping from the cooling component from affecting the heating efficiency of the heating component.

[0067] Optionally, as not shown in the figure, the above-mentioned thread raceway quenching equipment may further include a coolant supply unit, which may include a water pump and a storage tank.

[0068] Preferably, the above-mentioned thread raceway quenching equipment can have two sets of coolant supply units. One of the two coolant supply units can be connected to the induction coil 124 to provide coolant to the induction coil 124; the other of the two coolant supply units can be connected to the cooling assembly to provide coolant to the cooling assembly. This achieves the independence of the coolant circulation of the cooling assembly and the coolant circulation of the induction coil 124, reducing the temperature interference between the two coolant circulations.

[0069] Alternatively, the above-mentioned thread raceway quenching equipment may also have only one coolant supply unit, that is, the induction coil 124 and the cooling components are both connected to the coolant supply unit, which can effectively reduce equipment costs and compress equipment size.

[0070] Preferably, such as Figure 1 As shown, the above-mentioned thread raceway quenching equipment may further include a rotary drive unit 4 for driving the workpiece 3 to rotate. The rotary drive unit 4 may be connected to both ends of the workpiece 3 to drive the rotation of the workpiece 3.

[0071] Optionally, the aforementioned rotary drive can be a rotary motor.

[0072] Preferably, as not shown in the figure, the above-mentioned thread raceway quenching equipment may further include a lifting drive unit, and the heating component and the cooling component are both fixed to the lifting drive unit to drive the heating component and the cooling component to move along the extension direction of the workpiece 3, thereby enabling the heating component and the cooling component to move along the extension direction of the workpiece 3 as the workpiece 3 rotates.

[0073] Optionally, the aforementioned lifting drive unit may include a linear drive device and a mounting bracket that are connected to each other, so as to drive the mounting bracket to move along the direction of gravity via the linear drive device. The aforementioned magnetic guide part 125, mounting guide ring 11 and cooling assembly may all be fixed on the mounting bracket.

[0074] It should be noted that the aforementioned rotary drive unit 4 and lifting drive unit are existing structures in the art and will not be described in detail here.

[0075] The second aspect of this application also provides a processing system including the thread raceway quenching equipment of any of the above embodiments, and thus has all the beneficial technical effects of the thread raceway quenching equipment, which will not be repeated here.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
