Description

Technical Field

[0001] This utility model relates to the field of coaxial machining technology, and in particular to an auxiliary guiding mechanism for coaxial machining of the deep hole and outer circle of a gear shaft. Background Technology

[0002] The auxiliary guiding mechanism for coaxial machining of deep holes and outer diameters of gear shafts is based on a high-precision guide sleeve that can be precisely adjusted. By being mounted on the machine tool and strictly aligned, the tool (such as a boring bar) receives radial support and guidance that is completely consistent with the machine tool spindle (i.e., the workpiece rotation center) before it enters the workpiece. This forces and constrains the tool's trajectory during deep hole machining, effectively overcoming the problems of tool deflection, vibration, and skew caused by the slenderness of the tool. It fundamentally ensures extremely high coaxiality between the deep hole axis and the finishing outer diameter reference surface.

[0003] Existing auxiliary guidance mechanisms rely on a closed-loop system of perception, calculation, and execution to achieve precise guidance through the collaboration of multidisciplinary technologies. However, due to the difficulty in adjusting the spacing between the clamping devices according to actual conditions, they can only adapt to workpieces of a single size or a very small size range, resulting in low adaptability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary guiding mechanism for coaxial machining of the deep hole and outer circle of the gear shaft. The existing auxiliary guiding mechanism aims to improve the problem of low adaptability caused by the difficulty in adjusting the spacing between the clamping devices according to the actual situation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An auxiliary guide mechanism for coaxial machining of a deep hole and an outer circle of a gear shaft includes a base, a slide rail fixedly connected to the top of the base, a locking groove provided inside the slide rail, a sliding plate slidably connected inside the slide rail, a locking rod provided inside the locking groove, the locking rod slidably connected to the inside of the sliding plate, a support assembly provided inside the sliding plate, and the support assembly being disposed at one end of the locking rod.

[0006] Through the above technical solution: the base, as the core load-bearing component of the auxiliary guide mechanism, has a slide rail fixed at its top that provides a precise linear guide reference for the entire mechanism. By pulling the support component and the locking rod, the locking force between the sliding plate and the slide rail can be eliminated, thereby improving the adaptability of the device.

[0007] Preferably, the support assembly includes a first support spring, one end of which is disposed inside the sliding plate, and the other end of which is provided with a pull ring. The pull ring is slidably connected to the outside of the sliding plate, and the other end of the pull ring is fixedly connected to one end of the locking rod.

[0008] Preferably, the support assembly further includes a pull plate, the outside of which is disposed inside the sliding plate, a support rod is disposed inside the pull plate, and a locking block is fixedly connected to the bottom end of the pull plate, the outside of which is disposed inside the slide rail.

[0009] Preferably, the two ends of the support rod are fixedly connected to the inside of the sliding plate, and the outside of the pull plate is disposed inside the sliding plate.

[0010] Preferably, a protective shell is fixedly connected to the top of the sliding plate, and a pull handle is fixedly connected to the outside of the protective shell.

[0011] Preferably, the protective shell has a clamping assembly inside, and the bottom end of the clamping assembly is located at the top of the sliding plate.

[0012] Preferably, the clamping assembly includes a sliding rod, the outer side of which is slidably connected to the inside of the protective housing, the inner side of which is rotatably connected to a first rotating wheel, the outer side of which is fixedly connected to a sliding ramp, the inner side of which is slidably connected to a guide rod, the bottom end of which is provided with a second support spring, the outer side of which is provided with a second rotating wheel, the outer side of which is rotatably connected to a rotating rod, and the inner side of which is rotatably connected to a third rotating wheel.

[0013] Preferably, the bottom end of the guide rod is fixedly connected to the top end of the sliding plate, the outside of the sliding inclined plate is slidably connected to the inside of the protective shell, the outside of the guide rod is disposed inside the second support spring, the bottom end of the second support spring is disposed at the top end of the sliding plate, the outside of the second rotating wheel is disposed inside the protective shell, and the outside of the rotating rod is rotatably connected to the inside of the protective shell.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pulling the support component and driving the locking rod to slide, the sliding plate can be pushed to slide, and finally the effect of moving the clamping device is achieved. This allows the same set of auxiliary guide clamping devices to cover a wider range of workpiece sizes, eliminating the need to configure separate equipment for different specifications and effectively improving adaptability.

[0015] 2. In this utility model, the first rotating wheel, sliding rod and sliding inclined plate will slide under the compression of the gear shaft, and the second support spring will be compressed under the drive of the sliding rod, and then the guide rod will assist the sliding rod to slide. At the same time, the sliding inclined plate will drive the second rotating wheel to rotate and make the rotating rod rotate. Then the third rotating wheel will rotate outside the gear shaft, and finally the gear shaft will be locked. The dynamic stability of the gear shaft during the processing is significantly improved, reducing processing defects caused by external forces and reducing rework rate and scrap rate.

[0018] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figures 1-3 The present invention provides an embodiment of an auxiliary guide mechanism for coaxial machining of a deep hole and an outer circle of a gear shaft, comprising a base 1, a slide rail 2 fixedly connected to the top of the base 1, a locking groove 3 provided inside the slide rail 2, a sliding plate 4 slidably connected inside the slide rail 2, a locking rod 5 provided inside the locking groove 3, the locking rod 5 being slidably connected to the inside of the sliding plate 4, a support component 6 being provided inside the sliding plate 4, and the support component 6 being provided at one end of the locking rod 5. Specifically, the base 1 is used to support and fix the slide rail 2, and the slide rail 2 is used to assist the sliding plate 4 in sliding. The sliding plate 4 can be firmly locked inside the slide rail 2 by the locking rod 5 and the support component 6. At the same time, a baffle is fixed at the tail end of the slide rail 2, and a locking groove 3 is opened inside the slide rail 2. The locking groove 3 allows the locking rod 5 to slide in, and the baffle effectively prevents the sliding plate 4 from sliding out of the slide rail 2.

[0020] Reference Figure 1 and Figure 2 The support assembly 6 includes a first support spring 61. One end of the first support spring 61 is disposed inside the sliding plate 4, and the other end of the first support spring 61 is provided with a pull ring 62. The outside of the pull ring 62 is slidably connected to the inside of the sliding plate 4, and the other end of the pull ring 62 is fixedly connected to one end of the locking rod 5. Specifically, in this embodiment, the sliding plate 4 is used to support the first support spring 61 for stretching, and the sliding plate 4 is used to assist the pull ring 62 and the locking rod 5 in sliding. At the same time, pulling the pull ring 62 is used to drive the first support spring 61 to stretch, and the pull ring 62 is used to drive the locking rod 5 to slide from the inside of the slide rail 2 to the inside of the sliding plate 4, thereby moving the sliding plate 4. Then, releasing the pull ring 62 will cause the first support spring 61 to drive the locking rod 5 and the pull ring 62 to slide back to their original positions, thereby achieving the effect of moving the clamping device without the need to configure separate equipment for different specifications.

[0021] Example 2: Reference Figure 3 The support assembly 6 also includes a pull plate 63, the outside of which is disposed inside the sliding plate 4. A support rod 64 is disposed inside the pull plate 63. A locking block 65 is fixedly connected to the bottom end of the pull plate 63, and the outside of the locking block 65 is disposed inside the slide rail 2. The two ends of the support rod 64 are fixedly connected to the inside of the sliding plate 4, and the outside of the pull plate 63 is disposed inside the sliding plate 4. A protective shell 7 is fixedly connected to the top end of the sliding plate 4, and a pull handle 8 is fixedly connected to the outside of the protective shell 7. Specifically, in this embodiment, the sliding plate 4 is used to support and fix the support rod 64, and the sliding plate 4 is used to assist the pulling plate 63 in sliding. Pushing the pulling plate 63 upward will cause the locking block 65 to be squeezed out from the inside of the slide rail 2. Pulling the pulling plate 63 again will cause the locking block 65 to slide. With the assistance of the support rod 64, the pulling plate 63 slides and prevents the pulling plate 63 from being taken out from the inside of the sliding plate 4, effectively preventing the loss of the pulling plate 63, thereby achieving the effect of a movable clamping device and effectively improving adaptability.

[0022] Example 3: Reference Figure 1 and Figure 4The protective housing 7 has a clamping assembly 9 inside, with its bottom end positioned at the top of the sliding plate 4. The clamping assembly 9 includes a sliding rod 91, which is slidably connected to the outside of the protective housing 7. A first rotating wheel 92 is rotatably connected inside the sliding rod 91. A sliding inclined plate 93 is fixedly connected to the outside of the sliding rod 91. A guide rod 94 is slidably connected inside the sliding rod 91. A second support spring 95 is located at the bottom of the sliding rod 91. A second rotating wheel 96 is located outside the sliding inclined plate 93. A rotating rod 97 is rotatably connected to the outside of the second rotating wheel 96. A third rotating wheel 98 is rotatably connected inside the rotating rod 97. The bottom end of the guide rod 94 is fixedly connected to the top of the sliding plate 4. The outside of the sliding inclined plate 93 is slidably connected to the inside of the protective housing 7. The outside of the guide rod 94 is located inside the second support spring 95. The bottom end of the second support spring 95 is located at the top of the sliding plate 4. The outside of the second rotating wheel 96 is located inside the protective housing 7. The outside of the rotating rod 97 is rotatably connected to the inside of the protective housing 7. Specifically, in this embodiment, the sliding plate 4 is used to support and fix the guide rod 94, and also to support and compress the second support spring 95. Simultaneously, the sliding plate 4 supports and fixes the protective shell 7, and the protective shell 7 assists the sliding rod 91 in sliding and the rotating rod 97 in rotating. Driven by the gear shaft, the first rotating wheel 92, the sliding rod 91, and the sliding inclined plate 93 slide together. The sliding rod 91 compresses the second support spring 95 and causes the guide rod 94 to slide into the sliding rod 91. The guide rod 94 provides guidance for the sliding rod 91 and effectively prevents the second support spring 95 from deforming during operation. The second rotating wheel 96 rotates outside the sliding inclined plate 93, and the rotating rod 97 rotates under the drive of the second rotating wheel 96. The rotating rod 97 supports the third rotating wheel 98, which rotates outside the gear shaft, thus locking the gear shaft and effectively reducing rework and scrap rates.

[0023] Working principle: When the clamping assembly 9 needs to be moved according to the length of the gear shaft, the first pull ring 62 is pulled to stretch the first support spring 61. Under the action of the pull ring 62, the locking rod 5 slides, which causes the locking rod 5 to slide out from the inside of the locking groove 3. Then, the connection between the slide rail 2 and the sliding plate 4 is loosened. The locking block 65 can also be moved by lifting the pull plate 63 upward. The locking block 65 can be moved by pulling the pull plate 63 upward again. Then, the support rod 64 assists the pull plate 63 to slide and provides a guiding function. This can achieve the effect of moving the clamping device. The same set of auxiliary guide clamping devices can cover a wider range of workpiece sizes without the need to configure separate equipment for different specifications, effectively improving adaptability. When it is necessary to lock the gear shaft, the first rotating wheel 92 slides with the sliding rod 91 under the drive of the gear shaft. At the same time, the sliding rod 91 drives the sliding inclined plate 93 to slide and compresses the second support spring 95. Then the guide rod 94 slides into the sliding rod 91. Subsequently, the sliding inclined plate 93 drives the second rotating wheel 96 to rotate and causes the rotating rod 97 and the third rotating wheel 98 to rotate, thereby achieving the effect of locking the gear shaft. The dynamic stability of the gear shaft is significantly improved during the processing, reducing processing defects caused by external forces and reducing rework rate and scrap rate.

[0024] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
