Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spindle quenching devices, specifically to a local high-frequency quenching device for compressor spindles. Background Technology
[0002] As the core transmission component of the compressor, the compressor spindle must withstand continuous torque, radial force, and cyclic loads during operation. This places extremely high demands on the overall mechanical properties of the spindle, especially the hardness, wear resistance, and fatigue strength of key stress-bearing parts. Local quenching, a key technology for improving the performance of specific parts of shaft components, involves targeted heating and cooling of easily worn and high-stress areas of the spindle. This significantly enhances local properties while maintaining the overall toughness of the spindle, thereby extending its service life and improving the reliability of the compressor.
[0003] However, current local quenching devices used in compressor spindles generally suffer from numerous technical challenges. Regarding spindle driving and positioning, traditional devices often employ a fixed clamping drive structure. This structure not only struggles to adapt to spindles of different lengths and diameters, resulting in poor equipment versatility, but also suffers from insufficient spindle centering accuracy during drive, causing eccentric wobbling during spindle rotation and consequently shifting the quenching zone position, thus affecting quenching accuracy. While some devices utilize a sliding drive structure, their sliding stability is insufficient, and they lack the ability to precisely control the spindle rotation speed. This prevents them from achieving uniform rotation according to the quenching process requirements of spindles made of different materials, further exacerbating the instability of quenching quality. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a local high-frequency quenching device for compressor spindle, which can effectively solve the problems in the existing technology.
[0005] This utility model provides a local high-frequency quenching device for compressor spindles, including an operating table. Multiple sets of sliding grooves are equidistantly formed at the top of the operating table. Multiple sets of slide rails are fixed to the top of the operating table. An active drive structure is provided on the slide rails. A quenching structure is provided within the sliding grooves, and a spindle is provided within the quenching structure. The two sides of the spindle are mounted on the top of the active drive structure. The active drive structure includes a sliding table, an upper platform fixed to the top of the sliding table, two sets of servo motors located inside the upper platform, and rollers fixedly connected to the output ends of the two sets of servo motors. The quenching structure includes a mounting frame, a control device fixed to the mounting frame, and a slider. One end of the control device is electrically connected to a high-frequency heating copper ring, and the high-frequency heating copper ring is located on the outside of the spindle.
[0006] Furthermore, a sliding groove is provided at the bottom center of the slide table, and the sliding groove slides with the slide rail. A groove is provided at the center of the upper platform, and the servo motor is installed in the groove.
[0007] Furthermore, the output end of the servo motor is fixedly connected to the bottom of the turntable, the top end of the turntable is fixedly connected to the rollers, and the middle part of a set of rollers is fixedly connected to the driven wheel. One end of the driven wheel is meshed with the driving gear of the motor, and the bottom end of the motor is fixed on the turntable.
[0008] Furthermore, the slider is fixed to the bottom end of the mounting bracket, and the slider is disposed within the slide groove.
[0009] Furthermore, the top of the operating table is provided with multiple sets of quenching structures, and each set of quenching structures is fitted at different positions on the spindle.
[0010] The beneficial effects of this utility model are as follows: The active drive structure of this device adopts a sliding design with a slide rail and a slide table. The sliding groove at the bottom of the slide table is precisely matched with the slide rail at the top of the operating table, ensuring excellent guidance and stability of the slide table during sliding. The spacing between the two sets of active drive structures can be flexibly adjusted according to the spindle length to adapt to the support requirements of different spindle specifications, significantly improving the versatility of the device. At the same time, the active drive structure drives the corresponding rollers through two sets of servo motors. The servo motors have high-precision angle control capabilities, which can achieve precise control of the roller speed, thereby ensuring that the spindle rotates stably at a set uniform speed. In conjunction with the motor, the rollers are driven by the meshing transmission between the driven wheel and the active gear, further improving the stability of the driving power, effectively avoiding eccentric wobbling during spindle rotation, ensuring the coaxiality of the high-frequency heating copper ring and the spindle, making the quenching area heated evenly, and greatly improving the quenching accuracy and quality stability. The roller structure with a rotation function can adjust the angle with the spindle. When rotating in contact with the spindle, the spindle can be moved to one side to facilitate the next operation.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the embodiments.
[0016] Example: A local high-frequency hardening device for compressor spindles, see attached figure. Figure 1 - Appendix Figure 4The device includes an operating table 1, with multiple sets of sliding grooves 11 evenly spaced at the top of the operating table 1. Multiple sets of slide rails 2 are fixed to the top of the operating table 1, and an active drive structure 3 is installed on the slide rails 2. A quenching structure 5 is installed in the sliding groove 11, and a main shaft 4 is installed in the quenching structure 5. The two sides of the main shaft 4 are mounted on the top of the active drive structure 3. The active drive structure 3 of this device adopts a sliding design in which the slide rail 2 and the sliding table 31 cooperate. The sliding groove 311 at the bottom of the sliding table 31 is precisely matched with the slide rail 2 at the top of the operating table 1, ensuring that the sliding table 31 has excellent guidance and stability during sliding. The spacing between the two sets of active drive structures 3 can be flexibly adjusted according to the length of the main shaft 4 to adapt to the support requirements of different specifications of main shaft 4, which significantly improves the versatility of the device. Meanwhile, the active drive structure 3 drives the corresponding rollers 32 through two sets of servo motors 352. The servo motors 352 have high-precision angle control capabilities, which can accurately control the rotation speed of the rollers 32, thereby ensuring that the spindle 4 rotates stably at the set uniform speed. In conjunction with the motor 34, the rollers 32 are driven by the meshing transmission between the driven wheel 33 and the active gear 341, which further improves the stability of the driving power, effectively avoids the eccentric wobbling when the spindle 4 rotates, ensures the coaxiality of the high-frequency heating copper ring 52 and the spindle 4, makes the quenching area heat up evenly, and greatly improves the quenching accuracy and quality stability.
[0017] The active drive structure 3 includes a slide table 31, an upper platform 35 fixed to the top of the slide table 31, two sets of servo motors 352 located inside the upper platform 35, and rollers 32 fixedly connected to the output ends of the two sets of servo motors 352. The quenching structure 5 includes a mounting bracket 54, a control device 51 fixed on the mounting bracket 54, and a slider 53. One end of the control device 51 is electrically connected to the high-frequency heating copper ring 52, and the high-frequency heating copper ring 52 is located on the outside of the spindle 4. Multiple sets of quenching structures 5 are equidistantly arranged along the slide groove 11 at the top of the operating table 1. The position of each set of quenching structures 5 can be adjusted by sliding the slider 53 in the slide groove 11, so that the high-frequency heating copper rings 52 of each set of quenching structures 5 are accurately fitted onto different key parts of the spindle 4, realizing multi-area synchronous quenching treatment. Compared to the traditional single-group quenching mechanism that requires multiple positioning and quenching operations, this device eliminates the need for multiple disassembly and reassembly of the spindle 4. It can complete the quenching operations of multiple local areas of the spindle 4 in one go, which not only greatly shortens the production cycle and improves production efficiency, but also avoids the cumulative errors caused by multiple positioning, ensuring that the positional accuracy of each quenching area remains consistent, and effectively improving the uniformity of the overall performance of the spindle 4.
[0018] A sliding groove 311 is provided in the middle of the bottom end of the slide table 31. The sliding groove 311 slides with the slide rail 2. A groove 351 is provided in the middle of the upper platform 35. The servo motor 352 is installed in the groove 351. The output end of the servo motor 352 is fixedly connected to the bottom of the turntable 353. The top of the turntable 353 is fixedly connected to the roller 32. The middle of a set of rollers 32 is fixedly connected to the driven wheel 33. One end of the driven wheel 33 is meshed with the driving gear 341 of the motor 34. The bottom end of the motor 34 is fixed on the turntable 353.
[0019] The slider 53 is fixed to the bottom of the mounting bracket 54 and is located in the slide groove 11.
[0020] The sliding adjustment of the slide table 31 along the slide rail 2 in the active drive structure 3, and the sliding adjustment of the slider 53 along the slide groove 11 in the quenching structure 5, form a two-dimensional flexible adjustment system. This system can quickly adapt the drive support position to the quenching area position according to compressor spindles 4 of different diameters and lengths, without requiring the replacement of special fixtures or molds, significantly improving the device's adaptability to different specifications of spindles 4. Furthermore, by controlling the heating power of the high-frequency heating copper ring 52 through the control device 51, it can adapt to the local quenching process requirements of spindles 4 made of different materials (such as carbon steel, alloy steel, etc.), further expanding the device's applicability and reducing the cost of enterprises purchasing separate dedicated quenching equipment for different models of spindles 4.
[0021] Multiple sets of quenching structures 5 are installed at the top of the operating table 1, with each set of quenching structures 5 positioned at different locations on the spindle 4. This device adopts an integrated layout of "active drive structure 3 + multiple sets of quenching structures 5." The active drive structure 3 supports and rotates the spindle 4, forming a highly efficient synergy with the position adjustment and high-frequency heating of the quenching structures 5. The integrated design of the slide table 31 and the upper platform 35 provides a stable mounting base for drive components such as the servo motor 352 and rollers 32. The mounting bracket 54 provides an integrated mounting carrier for quenching components such as the control device 51 and the high-frequency heating copper ring 52, making the overall structure of the device compact and rationally laid out. Simultaneously, the direct electrical connection between the control device 51 and the high-frequency heating copper ring 52 enables rapid adjustment of heating parameters. Combined with the precise speed adjustment of the active drive structure 3, this allows operators to centrally set and adjust drive and heating parameters according to the different quenching process requirements of the spindle 4, reducing operational complexity and workload, and providing favorable conditions for the automated control of the quenching process.

Although this utility model 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 of the technical features.
