Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to an automatic calibration device for precision parts processing. Background Technology

[0002] Precision parts refer to individual components used to assemble machines. The processing of these parts involves multiple steps, and positioning and assembly is a crucial one. It requires assembling two parts that do not fit together properly to make them a single unit.

[0003] In existing technologies, the traditional precision parts machining and calibration methods present many challenges due to the small size of the parts, their tiny dimensions, and extremely high precision requirements. Precision parts are widely used in many fields, such as the core components of engines, whose manufacturing precision is directly related to safety and performance.

[0004] However, traditional clamping methods are insufficient for parts with similar shapes but slight differences, such as cylinders and slightly tapered parts. They can only accommodate parts within a specific shape and size range. For example, a common three-jaw chuck can achieve relatively stable clamping of cylindrical parts if the part's diameter is within the chuck's tolerance range. However, when dealing with slightly tapered parts, the chuck cannot automatically adjust its clamping force and position according to the taper, easily leading to uneven force distribution on the part. This not only fails to accurately clamp the part but also causes displacement during machining due to force imbalance. Therefore, we propose an automatic calibration device for precision parts machining. Utility Model Content

[0005] One of the technical problems this application aims to solve is: to be able to adapt to parts with similar but slightly different shapes, so as to facilitate subsequent processing.

[0006] To address the aforementioned technical problems, this application provides an automatic calibration device for precision parts machining, comprising: an adaptation mechanism, an auxiliary mechanism on one side of the adaptation mechanism, the adaptation mechanism including a platform, a conical plate on the inner surface of the platform, the inner surface of the platform being rotatably connected to the top end of the conical plate, a fixing plate on one inner end of the conical plate, the inner end of the conical plate being rotatably connected to the middle end of the fixing plate, a toothed plate on one bottom end of the conical plate, the bottom end of the conical plate being rotatably connected to one end of the toothed plate, and a fixing ring on the outer side of one end of the toothed plate, the outer side of one end of the toothed plate being slidably connected through the inner wall of the fixing ring.

[0007] In some embodiments, the auxiliary mechanism includes a support rod, one end of which is provided with a roller and is rotatably connected to the inner side of the roller. A side plate is provided on the outer side of the roller and slides in contact with the inner wall of the side plate. The other end of the support rod is provided with a guide rod and is fixedly connected to one side of the guide rod.

[0008] In some embodiments, a spring is provided at one end of the toothed plate, one end of the toothed plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the interior of the plate.

[0009] In some embodiments, the inner surface of the platform is provided with an inner plate, the inner surface of the platform and the outer side of the inner plate are slidably connected, a locking frame is provided on the top side of the inner plate, and the top side of the inner plate is fixedly connected to the bottom end of the locking frame.

[0010] In some embodiments, the outer side of the locking frame is connected through to the inner wall of the fixing ring, and the bottom side of the locking frame is slidably engaged with the top side of the toothed plate.

[0011] In some embodiments, a horizontal plate is provided on the bottom side of the platform, and the bottom side of the platform is fixedly connected to one end of the horizontal plate. A lead screw is provided on the inner wall of the horizontal plate, and the inner wall of the horizontal plate is threadedly connected to the outer side of the lead screw. The top end of the lead screw is rotatably connected to the bottom side of the inner plate.

[0012] In some embodiments, one side of the platform is fixedly connected to one end of the guide rod, the bottom side of one end of the guide rod is fixedly connected to one end of the telescopic rod, and the bottom side of the telescopic rod is fixedly connected to one end of the inner side of the side plate.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. Press the part into the fixing plate, which will increase the distance between the bottom ends of the four conical plates, thus increasing the diameter between the four conical plates. At the same time, the four fixing plates will also separate, increasing the diameter. At this time, the toothed plate will pass through the fixing ring and enter the platform. After the part enters, because there are springs designed inside the platform, the springs will immediately release elastically, further increasing the fit between the fixing plate and the part. This can adapt to the processing of various precision parts with similar shapes but different diameters. Whether it is a cylindrical part or a slightly tapered part, it can be accurately calibrated and fixed.

The top of the lead screw is rotatably connected to the inner plate, and the inner plate is fixedly connected to the bottom of the locking frame. At this time, the lead screw is rotated, causing the position of the lead screw in the horizontal plate to move down. At the same time, the inner plate and the locking frame move down a short distance synchronously, so that the locking frame and the toothed plate engage, keeping the position of the toothed plate still, thereby fixing the fixing plate and preventing loosening.

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.

[0026] Example 1: Please refer to Figures 1-6This utility model provides a technical solution: an automatic calibration device for precision parts machining, comprising: an adaptation mechanism 1, an auxiliary mechanism 2 disposed on one side of the adaptation mechanism 1, the adaptation mechanism 1 including a platform 11, a conical plate 12 disposed on the inner surface of the platform 11, the inner surface of the platform 11 being rotatably connected to the top end of the conical plate 12, a fixing plate 13 disposed at one inner end of the conical plate 12, the inner end of the conical plate 12 being rotatably connected to the middle end of the fixing plate 13, and the bottom of the conical plate 12... A toothed plate 14 is provided on one side of the cone plate 12. The bottom end of the cone plate 12 is rotatably connected to one end of the toothed plate 14. A retaining ring 15 is provided on the outer side of one end of the toothed plate 14. The outer side of one end of the toothed plate 14 is slidably connected to the inner wall of the retaining ring 15. A spring piece 16 is provided on one end of the toothed plate 14. One end of the toothed plate 14 is fixedly connected to one end of the spring piece 16. The other end of the spring piece 16 is fixedly connected to the inside of the platform 11. An inner plate 18 is provided on the inner surface of the platform 11. The inner surface of the platform 11 is connected to the inner plate 18. The outer side of the inner plate 18 is slidably connected to the inner plate 18. A locking frame 17 is provided on the top side of the inner plate 18. The top side of the inner plate 18 is fixedly connected to the bottom end of the locking frame 17. The outer side of the locking frame 17 is connected through the inner wall of the fixing ring 15. The bottom side of the locking frame 17 is slidably engaged with the top side of the toothed plate 14. A horizontal plate 19 is provided on the bottom side of the platform 11. The bottom side of the platform 11 is fixedly connected to one end of the horizontal plate 19. A threaded rod 110 is provided on the inner wall of the horizontal plate 19. The inner wall of the horizontal plate 19 is threaded through the outer side of the threaded rod 110. The top of the lead screw 110 is rotatably connected to the bottom side of the inner plate 18. One side of the platform 11 is fixedly connected to one end of the guide rod 111. The bottom side of one end of the guide rod 111 is fixedly connected to one end of the telescopic rod 112. The bottom side of the telescopic rod 112 is fixedly connected to one end of the inner side of the side plate 113. The inner wall of the side plate 113 is in sliding contact with the outer side of the guide rod 111. A processing device 114 is provided at the top of the side plate 113. The top of the side plate 113 is fixedly connected to one side of the processing device 114.

[0027] This type of automatic calibration device for precision parts machining operates by first designing a platform 11, on the inner wall of which are installed four conical plates 12, which are assembled to form a conical tube. Each conical plate 12 has a fixing plate 13 located in the middle of its inner side. The four fixing plates 13 are assembled to form a circular tube, and the inner side of the fixing plates 13 is used to place the part. Furthermore, to automatically calibrate and fix the part according to its diameter, a toothed plate 14 is provided at the bottom of the conical plate 12. A fixing ring 15 is designed on the outer side of the toothed plate 14. Therefore, when placing the part, slight force is required to press it into the fixing plate 13. The distance between the bottom ends of the four conical plates 12 will increase, thus increasing the diameter between the four conical plates 12. At the same time, the four fixed plates 13 will also separate, increasing their diameter. At this time, the toothed plate 14 will pass through the fixed ring 15 and enter the platform 11. After the part enters, since there is a spring 16 designed inside the platform 11, the spring 16 will immediately release elastically, further increasing the fit between the fixed plate 13 and the part. This can adapt to the processing of various precision parts with similar shapes and different diameters. Whether it is a cylindrical part or a slightly tapered part, it can be accurately calibrated and fixed, expanding its application range in the field of precision parts processing.

[0028] To ensure that the fixed plate 13 remains stationary after expansion, a locking frame 17 is designed on the inner wall of the fixing ring 15. Both the locking frame 17 and the toothed plate 14 have toothed grooves. After the fixed plate 13 is adapted to the part, a horizontal plate 19 is designed on the bottom side of the platform 11, and a lead screw 110 is located in the horizontal plate 19. The top end of the lead screw 110 is rotatably connected to the inner plate 18, and the inner plate 18 is fixedly connected to the bottom end of the locking frame 17. At this time, rotating the lead screw 110 causes it to move downward within the horizontal plate 19, simultaneously causing the inner plate 18 and the locking frame 17 to move downward a short distance. This causes the locking frame 17 to engage with the toothed plate 14, keeping the toothed plate 14 stationary and thus fixing the fixed plate 13. This prevents loosening and effectively resists external forces such as severe vibrations and impacts generated during processing, providing a solid and reliable foundation for the processing of precision parts.

[0029] Secondly, four processing positions are provided on the table 11, and each has a conical plate 12 inside. A guide rod 111 is installed on one side of the table 11. The guide rod 111 is located inside the side plate 113. The side plate 113 not only has the guide rod 111, but also the processing equipment 114. Therefore, when the part in the first processing position is processed, the telescopic rod 112 connected to the guide rod 111 is extended in length, so that the guide rod 111 drives the table 11 to move in stages, so that the second processing position on the table 11 corresponds to the processing equipment 114.

[0030] Example 2: Please refer to Figure 1The auxiliary mechanism 2 includes a support rod 21, one end of which is provided with a roller 22, which is rotatably connected to the inner side of the roller 22. The outer side of the roller 22 is provided with a side plate 113, which slides in contact with the inner wall of the side plate 113. The other end of the support rod 21 is provided with a guide rod 111, which is fixedly connected to one side of the guide rod 111.

[0031] A support rod 21 is installed on one side of the guide rod 111, and a roller 22 is designed on the other end of the support rod 21. Therefore, during the movement of the guide rod 111, it slides in the side plate 113 by relying on the roller 22 on the support rod 21, which transforms the traditional sliding friction into rolling friction. Compared with sliding friction, the coefficient of rolling friction is extremely small, which can significantly reduce the resistance encountered by the guide rod 111 when it moves. This means that the power required to drive the guide rod 111 to move is greatly reduced, saving energy consumption. At the same time, the support rod 21 shares part of the pressure on the structure of the guide rod 111. During the processing, the equipment will bear the reaction force generated by the processing of the parts and the inertial force brought about by the movement of its own components. The presence of the support rod 21 changes the force distribution pattern, making the pressure borne by the guide rod 111 more evenly distributed in the entire support system.

[0032] Please see Figures 1-6When placing the part, a slight force is needed to press it into the fixing plate 13. This increases the distance between the bottom ends of the four conical plates 12, thus increasing the diameter between them. Simultaneously, the four fixing plates 13 separate, further increasing their diameter. At this point, the toothed plate 14 passes through the fixing ring 15 and enters the platform 11. Once the part is inside, a spring 16 is designed inside the platform 11, which immediately releases elastically, further increasing the fit between the fixing plate 13 and the part. A locking frame 17 is designed on the inner wall of the fixing ring 15, and both the locking frame 17 and the toothed plate 14 have grooves. After the fixing plate 13 and the part are properly aligned, a horizontal plate 19 is designed on the bottom side of the platform 11, and a lead screw 110 is located in the horizontal plate 19. The top of the lead screw 110 is rotatably connected to the inner plate 18. 18 is fixedly connected to the bottom end of the locking frame 17. At this time, the lead screw 110 is rotated, causing the lead screw 110 to move down within the horizontal plate 19. At the same time, the inner plate 18 and the locking frame 17 move down synchronously by a short distance, thereby engaging the locking frame 17 with the toothed plate 14, keeping the toothed plate 14 in place, thus fixing the fixing plate 13 and preventing loosening. A guide rod 111 is installed on one side of the table 11. The guide rod 111 is located inside the side plate 113. The side plate 113 not only has the guide rod 111, but also the processing equipment 114. Therefore, after the part in the first processing position is processed, the telescopic rod 112 connected to the guide rod 111 is extended in length, causing the guide rod 111 to drive the table 11 to move in stages, so that the second processing position on the table 11 corresponds to the processing equipment 114.

[0033] During the movement of the guide rod 111, it slides within the side plate 113 by relying on the roller 22 on the support rod 21, transforming the traditional sliding friction into rolling friction. Compared to sliding friction, the coefficient of rolling friction is extremely small, which can significantly reduce the resistance encountered by the guide rod 111 when it moves. This means that the power required to drive the guide rod 111 to move is greatly reduced.
