Description

Technical Field

[0001] This invention relates to the field of aircraft model parts processing technology, specifically a chamfering device for processing nuts for aircraft model engines. Background Technology

[0002] Nuts for model aircraft engines are critical components in the assembly process. Their structural precision directly affects the assembly stability and operational safety of the model aircraft engine. Chamfering is an important process in the production of these nuts, mainly used to remove burrs and sharp corners from the edges of the nut, making the edges smooth for subsequent assembly operations, while also improving the overall structural integrity of the nut. Because model aircraft products have high requirements for the dimensional accuracy and structural characteristics of components, model aircraft engine nuts often adopt a thin-walled structure design and need to adapt to the assembly requirements of different model aircraft engines, resulting in various size specifications. Therefore, higher requirements are placed on the clamping method and processing adaptability of the nut chamfering process.

[0003] Currently, when processing nuts for model aircraft engines, existing chamfering devices mostly use fixed fixtures to hold and position the nuts. The structure of these fixed fixtures is fixed and can only be used for nuts of a single size. When chamfering is required for nuts of different sizes, workers need to manually disassemble the original fixture, reinstall a fixture that is compatible with the new size nut, and repeatedly adjust the tool angle. The operation process is cumbersome, consumes a lot of time and labor costs, and affects processing efficiency. Meanwhile, due to the thin-walled nature of nuts used in model aircraft engines, the clamping force of the fixing fixture cannot be flexibly adjusted, which can easily cause extrusion on the nut surface, leading to clamping deformation of the nut and subsequent deviation in chamfer dimensions, thus failing to meet the high-precision machining requirements of nuts used in model aircraft engines. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a chamfering device for machining nuts for model aircraft engines, which solves the problem of using fixed fixtures in existing technologies, which requires disassembling fixtures, adjusting tool angles, and is cumbersome when changing models.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chamfering device for machining nuts for model aircraft engines, comprising: The base has support platforms fixedly connected to the top left and right sides of the base. Pushing mechanisms are provided on opposite sides of the two support platforms. A pad is fixedly connected to the center of the top of the base. A pushing mechanism is provided on the rear side of the pad. An extrusion strip is fixedly connected to the groove at the top of the pad. A nut is provided on the top of the extrusion strip. An extrusion mechanism is provided on the top of the pad. The transfer module has a groove at the center of its bottom, and evenly distributed placement slots on both the left and right sides of the groove. The left side of the transfer module has two engaging slots. The clamping mechanism includes several limiting bars, several clamping posts are slidably arranged inside the several limiting bars, springs are sleeved on the top of each of the several clamping posts, and corresponding plates are arranged between the tops of the several springs.

[0006] Preferably, the pushing mechanism includes a first fixing strip, which is fixedly connected to the pad. First support members are rotatably connected to both the front and rear sides of the right side of the first fixing strip. Arc-shaped connectors are rotatably connected to one side of each of the two first support members. Second support members are rotatably connected to one side of each of the two arc-shaped connectors. A pushing plate is provided between the centers of the two arc-shaped connectors.

[0007] Preferably, the extrusion mechanism includes a support plate, which is fixedly connected to the support protruding around the pad, and a first hydraulic cylinder is fixedly connected to the center of the top of the support plate.

[0008] Preferably, the pushing mechanism includes a second hydraulic cylinder, which is fixedly connected to the support platform. A sliding plate is fixedly connected to the output end of the second hydraulic cylinder, and the sliding plate is slidably connected to the support platform.

[0009] Preferably, the pusher plate and the extrusion strip are slidably connected, a second fixing strip is rotatably connected to the left side of the second support member at the rear, a connecting strip is provided between the other sides of the two arc-shaped connecting members, and the second fixing strip is fixedly connected to the pad.

[0010] Preferably, the output end of the first hydraulic cylinder passes through the support plate and is fixedly connected to the transfer module. The top left and right sides of the transfer module are fixedly connected to sliding columns, and the top ends of the two sliding columns pass through and are slidably connected to the support plate.

[0011] Preferably, the limiting strip is composed of two corresponding strips with the same shape, and the two strips are fixed together by screws. Limiting blocks are fixedly connected to both sides of one of the strips, and the limiting blocks are slidably connected to the placement groove.

[0012] Preferably, each of the two engagement slots is slidably connected with an engagement strip, and the engagement slots and placement slots on adjacent sides of the engagement strips are interleaved.

[0013] Preferably, a cutting mechanism is fixedly connected to the top of both sliding plates.

[0014] Preferably, the corresponding plate is located at the top of the groove opened on the transfer module, and the corresponding plate is fixedly connected to the groove opened on the transfer module.

[0015] Working principle: Before operation, the model engine to be processed should be neatly arranged vertically on the extrusion strip in the groove at the top of the pad with nuts. At this time, each mechanism is in the initial standby state. The pushing mechanism, extrusion mechanism, pushing mechanism and cutting mechanism are not started. The clamping mechanism is in a high position with the transfer module and does not contact the nuts. Once preparation is complete, the feeding mechanism starts, and the drive motor on its left side begins to operate. The drive motor outputs power to rotate the second support member on the front side. Because the second support member is rotatably connected to the arc-shaped connecting member, and the second support member on the front side performs an eccentric movement, it causes the two arc-shaped connecting members to move synchronously. The movement of the arc-shaped connecting members, in turn, drives the two first support members rotatably connected to them to move in conjunction. Since the first fixing strip is fixedly connected to the pad, and the first support member is rotatably connected to the first fixing strip, the two arc-shaped connecting members, during their movement, cause the feeding plate at their center to move linearly forward. The pusher plate is slidably connected to the extrusion strip and always fits the surface of the extrusion strip during the movement. While pushing the nuts arranged on the extrusion strip upward, it is smoothly pushed forward to the processing station at the top of the pad to complete the feeding and positioning. At this time, the pusher plate remains in its original position and waits for subsequent reset. Once the nut is pushed to the designated processing station, the feeding mechanism stops working, and the extrusion mechanism starts operating. The first hydraulic cylinder in the extrusion mechanism is fixed at the top center of the support plate, and the support plate is fixedly connected to the protruding support structure around the pad. After the first hydraulic cylinder starts, its output end extends downwards, driving the transfer module fixedly connected to it to move downwards synchronously. The transfer module has a groove at its bottom center, and evenly distributed placement slots on both sides of the groove. The clamping mechanism is installed in the groove of the transfer module through a sliding connection between the limiting strip and the placement slot. The limiting strip is composed of two identical strips, fixed with screws. Limiting blocks are fixedly connected to both sides of one of the strips. The limiting blocks slide in the placement slot. As the transfer module moves downward, the bottoms of several clamping posts in the clamping mechanism gradually contact the tops of the nuts on the processing station. Because the nut is placed vertically and there may be slight differences in size, when the clamping post comes into contact with the nut, the clamping post that comes into contact with the nut will be pushed upward by the nut, and the spring sleeved at its top will be compressed and deformed. The clamping posts that do not contact the nuts remain in place and do not move. Meanwhile, the corresponding plate is fixed to the top of the transfer module groove and is located at the top of the clamping posts. In addition, two locking slots on the left side of the transfer module are slidably connected with locking strips, and the locking slots on adjacent sides are staggered with the placement slots. After the nut is clamped and fixed, the chamfering process is started. The two pushing mechanisms work synchronously. The second hydraulic cylinder in the pushing mechanism is fixedly connected to the support platform. The support platform is symmetrically fixed on the left and right sides of the top of the base. After the second hydraulic cylinder is started, its output end extends towards the center of the device, driving the sliding plate fixedly connected to it to slide along the support platform. The cutting mechanism fixedly connected to the top of the sliding plate moves towards the center synchronously with the sliding plate until the two cutting mechanisms are aligned with the left and right ends of the nut respectively. At the same time, the two servo motors in the two cutting mechanisms start simultaneously. The servo motors transmit power to the reducer at the bottom of the motor through belt drive. After the reducer reduces the power and increases the torque, it drives the cutting tool to rotate at high speed. The two cutting mechanisms move synchronously towards the center under the drive of the pushing mechanism, and the two reducers work synchronously. The two cutting tools simultaneously perform chamfering operations on the left and right ends of the same nut. During the chamfering process, the clamping mechanism always keeps the nut clamped and fixed. After the chamfering of the nut is completed, the servo motor in the cutting mechanism stops working, the cutting tool stops rotating, the output ends of the two second hydraulic cylinders retract, driving the sliding plate and the cutting mechanism to reset to both sides and return to the initial position. Subsequently, the output end of the first hydraulic cylinder retracts, driving the transfer module and the clamping mechanism to move upward, and the clamping column resets under the elastic force of the spring, releasing the clamping of the processed nut. Finally, the pushing mechanism starts again, driving the pushing plate to continue moving forward, pushing the finished nut out of the processing station, and at the same time pushing the next nut to be processed to the processing station, starting the next processing cycle.

[0016] This invention provides a chamfering device for machining nuts used in model aircraft engines. It has the following advantages: 1. This invention achieves the technical effect of stably clamping model nuts of different sizes without damaging them by adopting an adaptive clamping technology solution that uses a clamping mechanism and a transfer module in sliding cooperation and a spring sleeve on the clamping column. Compared with the existing technology that uses a fixed clamp, this invention solves the problems of disassembling the clamp, adjusting the tool angle, and cumbersome operation when changing models. At the same time, it avoids the clamping deformation problem caused by the thin-walled characteristics of the model nut by the fixed clamp.

[0017] 2. The present invention adopts an automated feeding technology solution through the linkage of the pusher mechanism with the support component, the arc-shaped connecting component and the pusher plate, which achieves the technical effect of continuous, stable and automatic feeding and resetting of nuts. Compared with the existing technology of manual feeding or cumbersome feeding mechanism, it solves the problems of low feeding efficiency, high manual operation intensity, inaccurate feeding position and easy to affect the smoothness of chamfering process.

[0018] 3. This invention adopts a bidirectional automated chamfering technology solution that uses a pushing mechanism to drive the cutting mechanism to move precisely and a servo motor to drive the tool rotation through a belt and pulley in conjunction with a reducer. This achieves the technical effect of bidirectional synchronous chamfering of nuts, precise processing, and convenient operation. Compared with the existing technology of chamfering in a single direction and requiring manual adjustment of the chamfering angle, this invention solves the problems of low chamfering efficiency, cumbersome angle adjustment, and easy deviation of chamfering dimensions due to human operation errors.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 3 and attached Figure 5 - Appendix Figure 8 This invention provides a chamfering device for machining nuts for model aircraft engines, comprising: The base 1 has a support platform 3 fixedly connected to the top left and right sides of the base 1. The two support platforms 3 are provided with a pushing mechanism 6 on opposite sides. The base 1 has a pad 2 fixedly connected to the top center. The pad 2 has a pushing mechanism 9 on the rear side. The pad 2 has an extrusion strip 7 fixedly connected to the groove on the top of the pad 2. The extrusion strip 7 has a nut 8 on the top of the extrusion strip 7. The pad 2 has an extrusion mechanism 5 on the top. The transfer module 501 has a groove at the center of its bottom, and evenly distributed placement slots 5012 are provided on both the left and right sides of the groove. The transfer module 501 has two engaging slots 5011 on its left side. The clamping mechanism 505 includes several limiting bars 5052, several clamping posts 5051 are slidably arranged inside the several limiting bars 5052, and springs 5053 are sleeved on the top of each of the several clamping posts 5051. Corresponding plates 5055 are arranged between the tops of the several springs 5053. The extrusion mechanism 5 includes a support plate 502, which is fixedly connected to the support protruding around the pad 2, and a first hydraulic cylinder 503 is fixedly connected at the center of the top of the support plate 502. The output end of the first hydraulic cylinder 503 passes through the support plate 502 and is fixedly connected to the transfer module 501. The top left and right sides of the transfer module 501 are fixedly connected to sliding columns 504, and the top ends of the two sliding columns 504 pass through and are slidably connected to the support plate 502.

[0023] Specifically, the bottom of the clamping column 5051 is a hemispherical structure, and the hemispherical structure is made of rubber. The clamping mechanism 505 is installed by sliding connection between the limiting strip 5052 and the placement slot 5012 of the transfer module 501. The limiting strip 5052 consists of two corresponding long strips fixed by screws. The limiting blocks 5054 on both sides of the limiting strip 5052 slide with the placement slot 5012, which can adjust the position of the clamping mechanism 505 in the groove of the transfer module 501, or add or remove the clamping mechanism 505 as needed. The engaging strip 5056 slides in the engaging groove 5011 and intersects with the placement slot 5012 to limit the limiting blocks 5054 and prevent the clamping mechanism 505 from shifting. The corresponding plate 5051 is fixed to the top of the groove of the transfer module 501 and supports the spring 5053. The clamping post 5051 is slidably set on the limiting strip 5052. Inside plate 52, a spring 5053 is fitted at the top and engages with the corresponding plate 5055. When the transfer module 501 moves downward, the bottom of the clamping column 5051 contacts the nut 8 and is lifted up. The spring 5053 is compressed to generate elastic force, and the clamping column 5051 that is not in contact with the nut 8 remains in its original position. This adaptive engagement achieves clamping and fixing of the nut 8. This clamping mechanism can achieve adaptive clamping of nuts 8 of different sizes without manual adjustment. The clamping position is adjusted by the sliding engagement of the limiting strip 5052 and the placement groove 5012. The engagement of the locking strip 5056 and the limiting block 5054 ensures clamping stability. The engagement of the spring 5053 and the clamping column 5051 achieves adaptive clamping, effectively ensuring that the nut 8 does not shift during processing and guaranteeing the reliability of clamping. Please see the appendix Figure 2 - Appendix Figure 4 and attached Figure 9 The limiting strip 5052 is composed of two corresponding strips with the same shape. The two strips are fixed together by screws. Limiting blocks 5054 are fixedly connected to both sides of one strip. The limiting blocks 5054 are slidably connected to the placement groove 5012.

[0024] Both locking slots 5011 are slidably connected with locking strips 5056, and the locking slots 5011 and placement slots 5012 on adjacent sides are interleaved. The corresponding plate 5055 is located at the top of the groove opened on the transfer module 501, and the corresponding plate 5055 is fixedly connected to the groove opened on the transfer module 501.

[0025] The pushing mechanism 9 includes a first fixing strip 903, which is fixedly connected to the pad 2. The first fixing strip 903 is rotatably connected to the front and rear sides of the right side of the first fixing strip 903. The two first supporting members 902 are rotatably connected to one side of each of the two first supporting members 902. The two arc-shaped connecting members 904 are rotatably connected to one side of each of the two arc-shaped connecting members 904. The pushing plate 901 is arranged between the centers of the two arc-shaped connecting members 904. The pusher plate 901 is slidably connected to the extrusion strip 7. The second support member 905 on the rear side is rotatably connected to the second fixing strip 906. A connecting strip 907 is provided between the other sides of the two arc-shaped connecting members 904. The second fixing strip 906 is fixedly connected to the pad 2.

[0026] Specifically, the pushing mechanism 9 is fixedly installed to the pad 2 via a long strip-shaped first fixing strip 903. The first fixing strip 903 is fixed to the rear extension of the pad 2 by several countersunk bolts. The countersunk bolts are embedded inside the first fixing strip 903 to avoid the protruding surface affecting the movement of other parts. The first support member 902 is rotatably connected to the front and rear sides of the right side of the first fixing strip 903. The arc-shaped connector 904 has an L-shaped structure with rounded corners. It has three circular through holes, the diameter of which matches the pin shaft, and the curvature matches the movement trajectory of the pushing plate. The connecting ears at both ends of the connector have through holes that match the first support member 902 and the second support member 905. The inner wall of the through holes is provided with wear-resistant parts to reduce wear during rotation. The pin shaft is provided with retaining rings at both ends to prevent the pin shaft from falling off. The other side of the arc-shaped connector 904 is rotatably connected to the second support 905 via a pin. The rear second support 905 is fixed to the pad 2 via a second fixing strip 906 with the same structure as the first fixing strip 903. The second fixing strip 906 is fixed to the pad 2 via a countersunk bolt and is rotatably connected to the second support 905 via a pin. A rotation auxiliary component is provided between the pin and the rotating seat to improve the smoothness of rotation. Two arc-shaped connectors 904 are connected by a connecting strip 907. A rectangular plate-shaped pusher plate 901 is set at the center. The pusher plate 901 is perfectly matched with the cross-sectional shape of the extrusion strip 7 and is slidably connected. When the drive motor drives the second support member 905 on the front side to rotate eccentrically, it drives the arc-shaped connectors 904 to move, which in turn drives the first support member 902 to move in conjunction, causing the pusher plate 901 to move linearly along the extrusion strip 7, pushing the nut 8 to the processing station. After cleaning, the drive motor rotates in the opposite direction, driving all components to reset. This feeding mechanism can automatically feed and reset the nut 8 without manual pushing. Through the rotational cooperation of each support and arc-shaped connector, the rotational motion of the motor is converted into the linear motion of the pusher plate 901. The connecting bar 907 ensures the synchronous movement of the two arc-shaped connectors 904. The sliding cooperation between the pusher plate 901 and the extrusion bar 7 ensures smooth pushing, effectively realizing continuous and precise feeding of the nut 8 and ensuring the smoothness of the processing flow.

[0027] Please see the appendix Figure 1 and attached Figure 2 The pushing mechanism 6 includes a second hydraulic cylinder 601, which is fixedly connected to the support platform 3. A sliding plate 602 is fixedly connected to the output end of the second hydraulic cylinder 601, and the sliding plate 602 is slidably connected to the support platform 3. Both sliding plates 602 are fixedly connected to the top of the cutting mechanism 4.

[0028] Specifically, the second hydraulic cylinder 601 is fixedly connected to the top surface of the support platform 3 via a flange. A sealing component is provided between the flange and the support platform 3 to prevent cutting fluid from seeping into the connection and causing corrosion during the machining process. The sliding plate 602 is a rectangular plate structure with a thickness that is adapted to the requirements of the cutting mechanism 4. The T-shaped slider at its bottom is fitted with the T-shaped groove at the top of the support platform 3 with a reasonable gap. The slider surface is coated with high-temperature grease to ensure smooth sliding and prevent jamming. The cutting mechanism 4 includes a mounting base, a servo motor, a reducer, a tool holder, a cutting tool, and a protective cover. The mounting base is an L-shaped plate structure, which is fixed to the top of the sliding plate 602 by bolts. The output shaft of the servo motor is connected to the pulley and the input shaft of the reducer by a belt. The reducer is a planetary gear reducer, and its output shaft is fixedly connected to the tool holder through an elastic collet. The tool holder is an elastic collet tool holder that is compatible with the cutting tool, which can quickly clamp and change the cutting tool. The cutting tool is a special chamfering tool, and the cutting edge angle is adapted to the chamfering requirements of nut 8. This pusher and cutting mechanism can achieve automated bidirectional chamfering of nut 8 without manual operation. The second hydraulic cylinder 601 drives the cutting mechanism 4 to move precisely. The servo motor controls the speed of the cutting tool through the belt and pulley in conjunction with the reducer. It can also ensure uniform chamfering of nut 8 by repeating the movement and processing steps, effectively ensuring the accuracy and safety of processing.
