Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of part detection, specifically relates to a detection device for the space size of aluminium alloy special-shaped part. BACKGROUND

[0002] With the improvement of the demand of light weight in the field of aerospace, automobile manufacturing and the like, the space size detection of aluminium alloy special-shaped part becomes the key link of quality control because of its complex curved surface, asymmetric structure and high precision requirement. The traditional detection device adopts rigid fixed clamp and single direction measurement structure, and has the following technical bottlenecks: firstly, the fixed mechanism is based on the design of plane positioning or fixed radian groove, and cannot adapt to the clamping requirement of multidirectional special-shaped contour, especially for the part with radial distribution characteristics or space twisted structure, the clamping is unstable, and the local stress concentration leads to micro deformation, which seriously affects the measurement authenticity; secondly, the part angle needs to be repeatedly disassembled and adjusted to realize multidirectional measurement in the detection process, and the operation is tedious and the repeated positioning error accumulates, which leads to low detection efficiency; thirdly, the existing three-dimensional detection equipment relies on multi-axis mechanical arm to drive the contact probe to scan, which can realize space measurement but the system is complex and expensive, and it is difficult to popularize and apply in small and medium-sized processing sites.

[0003] In recent years, although some researches use adjustable chuck to improve the clamping mode by cooperating with a rotary workbench, the radial adjusting mechanism of the traditional chuck is mostly linear slide rail layout, which is difficult to realize the synchronous adaptation of complex radian trajectory, and lacks self-locking stability structure after rotary positioning, and is easy to deviate due to vibration. In addition, the linkage between the measurement module and the clamping mechanism is insufficient, and the vertical direction adjustment mostly relies on manual lifting, and it is difficult to realize the rapid alignment of the detection reference surface and the special-shaped feature surface. Therefore, it is urgent to develop a special detection device integrating multidirectional flexible fixing, space angle self-locking and three-dimensional measurement linkage to solve the technical problems of high-precision and high-efficiency detection of special-shaped parts.

[0016] Due to the adoption of the above technical scheme, the utility model has the beneficial effects that:

[0017] 1. By setting the rotating seat and the fixing seat, a multi-directional adjustment fixing mode is provided, so that complex special-shaped parts can be stably clamped. The design of the arc-shaped grooves allows the fixing assembly to slide in multiple directions, adapts to the fixing needs of different shaped parts, and avoids the problem of micro-deformation caused by local stress concentration. The setting of the rotating seat allows the part to be conveniently adjusted in angle during detection, reduces the tedious operation of repeated disassembly and assembly, and improves the measurement efficiency.

[0018] By the design of the rotating seat and the fixed seat, the device can conveniently adjust the angle of the part during the detection process, reduce the repeated disassembly and assembly operations, and improve the measurement efficiency. The design of the arc-shaped groove and the fixing assembly ensures the stability of the part during clamping, avoiding the problem of micro-deformation caused by local stress concentration. Compared with traditional detection devices, the device has significant advantages in fixing method and measurement efficiency.

[0019] 2. By the sliding fit of the positioning column and the arc-shaped groove, it is ensured that the positioning column can freely slide in the arc-shaped groove, thereby realizing flexible adjustment of the position of the part. The limiting nut threadedly connected on the positioning column can effectively fix the position of the positioning column, avoiding loosening during sliding, and ensuring the stability of the part during detection. Through this design, the fixing assembly of the present application can adapt to parts of different shapes and sizes, especially for parts with complex curved surfaces and asymmetric structures, and has good adaptability.

[0020] 3. By providing a rubber fixing ball at the upper end of the positioning column, the problem that the fixing mechanism of traditional detection devices cannot adapt to the clamping requirements of multi-directional special-shaped profiles is solved. Specifically, the rubber fixing ball can provide flexible support when fixing the part, avoiding the problem of local stress concentration and micro-deformation caused by rigid fixing. Therefore, the application of the rubber fixing ball improves the authenticity and stability of the measurement.

[0021] 4. The rotating seat and the base are relatively rotated through rotating connection, the limiting plate is used to limit the rotation range of the rotating seat, the rotating seat can be fixed at a specific angle through the tightening nut, avoiding the deviation of the rotating seat caused by vibration or external force during detection, thereby ensuring the stability and precision of detection. The limiting plate design of the rotating seat side wall simplifies the structure of the device, facilitates the angle adjustment and fixation of the operator, and improves the convenience of operation and the reliability of detection.

[0022] 5. By fixedly connecting the driving gear on the base and setting the driven gear meshing with the driving gear at the bottom of the rotating seat, the rotating motion of the rotating seat is realized. In order to further control the rotation of the rotating seat, a self-locking motor is also provided at the bottom of the base for driving the driving gear to rotate. The use of the self-locking motor ensures that the driving gear can remain at the set position when the driving is stopped, and will not rotate due to external force, thereby ensuring the stability of the rotating seat.

[0023] 6. The vertical guide rail is provided to enable the C-shaped fixing frame to be flexibly adjusted in the vertical direction, facilitating the measurement of parts of different heights. The two arms of the C-shaped fixing frame are symmetrically arranged, further improving the stability of the overall structure. The size measurement assembly is installed on one of the arms and can be flexibly adjusted in position through sliding connection to adapt to the measurement requirements of different parts.

[0024] 7. The technical solution of the size measurement assembly can effectively realize accurate detection of the spatial size of the part by arranging the size detector on the mounting base and providing the detection probe at the detection end. The mounting base is provided with a bushing, a push rod is slidably connected in the bushing, and the push rod is fixedly connected with the mounting base. This design ensures that the detection probe can remain stable during detection, avoiding measurement errors caused by vibration or other factors.

[0025] 8. By arranging the size detector and the detection probe on the mounting base and through the sliding fit design of the bushing and the push rod, high-precision detection of the spatial size of the part is realized. Compared with the prior art, the technical solution of the present application can effectively solve the problems of unstable fixation, large measurement error and complicated operation of the traditional detection device, and improve the detection accuracy and efficiency.

[0026] 9. By using the vertical guide rail, screw rod and rotating cap in cooperation, flexible adjustment of the position of the C-shaped fixing frame is realized. Compared with the manual lifting method in the prior art, this scheme is more convenient to operate and more accurate to adjust, effectively solving the problem of difficult vertical adjustment in the prior art, and improving the practicality and operation efficiency of the detection device.

[0027] 10. The arc-shaped grooves are at least four, and the four arc-shaped grooves are in a rotational symmetry structure, and the front and rear ends of adjacent two arc-shaped grooves are on the same radius line of the fixing seat. This structure design makes the fixing assembly more evenly distributed around the fixing seat, so that it can better adapt to complex part shapes, especially those with radial distribution characteristics or spatially twisted structures. Through this rotational symmetric arc-shaped groove layout, the fixing assembly can provide stable support and fixation in different directions, avoiding the micro-deformation problem caused by unstable clamping or local stress concentration in the traditional clamping method.

[0028] In specific implementation, the number and layout of the arc-shaped grooves can be adjusted according to actual needs, such as determining the number and distribution of the arc-shaped grooves according to the size and shape of the part. By reasonably designing the radius and position of the arc-shaped grooves, the fixing assembly can always be in the best working state during clamping, thereby improving the accuracy and stability of detection.

By setting the rotating seat 2 and the fixed seat 3, a multi-directional adjustment fixing mode is provided, so that complex special-shaped parts can be stably clamped. The design of the arc grooves 31 allows the fixing assembly to slide in multiple directions, adapting to the fixing needs of different shaped parts and avoiding the problem of micro-deformation caused by local stress concentration. The setting of the rotating seat 2 allows the part to be easily adjusted in angle during the detection process, reducing the tedious operation of repeated disassembly and assembly and improving the measurement efficiency.

The design of the rotating seat 2 and the fixed seat 3 allows the parts to be adjusted at multiple angles and directions, adapting to the detection needs of complex special-shaped parts. The design of the arc-shaped grooves 31 allows the fixing assembly to slide in multiple directions, ensuring that the parts are stable and not easily deformed during clamping.

[0043] Through the design of the rotating seat 2 and the fixed seat 3, the device can conveniently adjust the angle of the parts during detection, reducing repeated disassembly and assembly operations and improving measurement efficiency. The design of the arc-shaped grooves 31 and the fixing assembly ensures that the parts are stable during clamping, avoiding the problem of micro-deformation caused by local stress concentration. Compared with traditional detection devices, the device has significant advantages in fixing method and measurement efficiency.

[0044] In summary, the aluminum alloy special-shaped part space size detection device provides a multi-directional adjustment fixing method through the design of the rotating seat 2 and the fixed seat 3, and the design of the arc-shaped grooves 31 and the fixing assembly ensures that the parts are stable during clamping, avoiding the problem of micro-deformation, improving measurement efficiency, and solving the technical bottleneck in traditional detection devices.

[0045] The fixing assembly includes a positioning column 4 that slidably fits with the arc-shaped grooves 31, and a limiting nut 41 that is threadedly connected to the positioning column 4.

[0046] The fixing assembly in this application ensures that the positioning column 4 can freely slide within the arc-shaped grooves 31 through the sliding fit of the positioning column 4 and the arc-shaped grooves 31, thereby achieving flexible adjustment of the position of the parts. The limiting nut 41 threadedly connected to the positioning column 4 can effectively fix the position of the positioning column 4, avoiding loosening during sliding and ensuring that the parts are stable during detection. Through this design, the fixing assembly of the present application can adapt to parts of different shapes and sizes, especially for parts with complex curved surfaces and asymmetric structures, and has good adaptability.

[0047] Specifically, the positioning column 4 can be made of high-strength material to ensure that it does not deform or break during use. The limiting nut 41 can be selected in different specifications as needed to adapt to positioning columns 4 of different sizes. The sliding fit of the positioning column 4 and the arc-shaped grooves 31 can be achieved through precision machining to ensure smooth and stable sliding. The thread connection of the limiting nut 41 can use standard threads or special threads to ensure the firmness and reliability of the connection.

[0048] By means of the technical scheme, the technical problems of the traditional detection device, such as the fixing mechanism being unable to adapt to the clamping requirement of multi-directional special-shaped profiles, unstable clamping, and micro-deformation caused by local stress concentration, are solved, and the detection efficiency and accuracy are improved. Compared with the prior art, the fixing assembly of the present application is more flexible and stable, and can adapt to the detection requirement of complex special-shaped parts, thereby significantly improving the performance and application range of the detection device.

[0049] The upper end of the positioning column 4 is provided with a rubber fixing ball 42. It is mentioned in the background art that the aluminum alloy special-shaped part has complex curved surfaces, asymmetric structure and high precision requirement, and the spatial size detection becomes a key link of quality control. The traditional detection device usually adopts rigid fixing clamps and single-direction measurement structure, and has significant technical bottlenecks, such as the fixing mechanism being based on plane positioning or fixed arc groove design, being unable to adapt to the clamping requirement of multi-directional special-shaped profiles, especially for parts with radial distribution characteristics or spatially twisted structure, unstable clamping, local stress concentration and micro-deformation often occur, which seriously affects the measurement authenticity. In addition, the part angle needs to be repeatedly disassembled and adjusted during the detection process to realize multi-directional measurement, which is tedious and repetitive positioning error accumulates, resulting in low detection efficiency.

[0050] The technical scheme of the present application solves the problem of the fixing mechanism of the traditional detection device being unable to adapt to the clamping requirement of multi-directional special-shaped profiles by providing a rubber fixing ball 42 at the upper end of the positioning column 4. Specifically, the rubber fixing ball 42 can provide flexible support when fixing the part, avoiding local stress concentration and micro-deformation caused by rigid fixing. Therefore, the application of the rubber fixing ball 42 improves the authenticity and stability of the measurement.

[0051] The rubber fixing ball 42 can be made of different hardness of rubber materials to adapt to the fixing requirement of different types of parts. Further, the diameter of the rubber fixing ball 42 can be adjusted according to the size and shape of the part to ensure the best fixing effect. For example, for larger size parts, a rubber fixing ball 42 with larger diameter can be used to provide larger support area and more stable fixing effect. As a preferred embodiment, the rubber fixing ball 42 can be connected with the positioning column 4 through threads or buckle structure, which is convenient for replacement and adjustment.

[0052] The technical scheme of the present application solves the problem of the fixing mechanism of the traditional detection device being unable to adapt to the clamping requirement of multi-directional special-shaped profiles, avoids local stress concentration and micro-deformation caused by rigid fixing, improves the authenticity and stability of the measurement. Compared with the prior art, the technical scheme of the present application simplifies the operation steps and improves the detection efficiency while ensuring high-precision measurement.

[0053] The side wall of the rotating seat 2 is provided with an upward limiting plate 23, and a top nut 24 adjacent to the side wall of the fixed seat 3 is threadedly connected to the limiting plate 23.

[0054] The rotating seat 2 is relatively rotatable with the base 1 through a rotating connection, and the limiting plate 23 is used to limit the rotation range of the rotating seat 2. The rotating seat 2 can be fixed at a specific angle through the top nut 24, so as to avoid the deviation of the rotating seat 2 due to vibration or external force during detection, thereby ensuring the stability and accuracy of detection. The limiting plate 23 on the side wall of the rotating seat 2 simplifies the structure of the device, facilitates the angle adjustment and fixation of the operator, and improves the convenience of operation and the reliability of detection.

[0055] Further, the design of the limiting plate 23 and the top nut 24 provides a simple and effective way to fix the angle of the rotating seat 2. The height and position of the limiting plate 23 can be adjusted according to actual needs to adapt to parts of different sizes and shapes. The top nut 24 is threadedly connected with the limiting plate 23, and when it is necessary to fix the rotating seat 2, the top nut 24 can be quickly fixed by being tightened, which is simple and reliable in fixing effect.

[0056] The application solves the problem of measurement error caused by unstable angle of the rotating seat 2 during multi-directional measurement of the traditional detection device by providing the limiting plate 23 on the side wall of the rotating seat 2 and fixing it through the top nut 24. This design not only improves the stability and measurement accuracy of the detection device, but also simplifies the operation steps and improves the detection efficiency. Compared with the prior art, the application provides a simple, convenient and low-cost solution with obvious technical advantages.

[0057] The base 1 is fixedly connected with a driving gear 22, the bottom of the rotating seat 2 is provided with a driven gear 21 engaged with the driving gear 22, and the bottom of the base 1 is provided with a self-locking motor for driving the driving gear 22 to rotate.

[0058] The application realizes the rotary motion of the rotating seat 2 by fixedly connecting the driving gear 22 on the base 1 and providing the driven gear 21 engaged with the driving gear 22 at the bottom of the rotating seat 2. In order to further control the rotation of the rotating seat 2, the base 1 is also provided with a self-locking motor at the bottom for driving the driving gear 22 to rotate. The use of the self-locking motor ensures that the driving gear 22 can remain at the set position when the driving is stopped, and will not rotate due to external force, thereby ensuring the stability of the rotating seat 2.

[0059] The self-locking motor can be realized by a conventional motor plus a self-locking device, such as a stepper motor or a motor with a mechanical brake. The number of teeth and the module of the driving gear 22 and the driven gear 21 can be selected according to the specific transmission ratio requirement to ensure that the rotating seat 2 can realize accurate angle adjustment. The gear transmission not only ensures the smooth rotation of the rotating seat 2, but also simplifies the driving structure and reduces the manufacturing cost.

[0060] Therefore, the application realizes accurate control and stable positioning of the rotating seat 2 through the meshing transmission of the driving gear 22 and the driven gear 21 and the driving of the self-locking motor. Compared with the prior art, the scheme of the application can effectively avoid the deviation problem caused by vibration and improve the measurement accuracy and operation stability of the overall device.

[0062] The technical scheme of the application sets the vertical guide rail 5 above the base 1, and slidably connects the C-shaped fixing frame 501 to the vertical guide rail 5, so that the C-shaped fixing frame 501 can freely slide on the vertical guide rail 5, facilitating the adjustment of the position of the C-shaped fixing frame 501. The C-shaped fixing frame 501 has two symmetrical arms, and the fixed seat 3 is located directly below the region between the two arms, which helps to maintain stability when fixing parts on the fixed seat 3. One of the arms is provided with a size measurement assembly, which can measure the size of the parts fixed on the fixed seat 3.

[0063] The setting of the vertical guide rail 5 enables the C-shaped fixing frame 501 to be flexibly adjusted in the vertical direction, facilitating the measurement of parts of different heights. The two arms of the C-shaped fixing frame 501 are symmetrically arranged, further improving the stability of the overall structure. The size measurement assembly is installed on one of the arms, and can be flexibly adjusted in position through the sliding connection, adapting to the measurement requirements of different parts.

[0064] Through the above technical scheme, the application solves the problem of insufficient linkage of the fixing mechanism and the measurement mechanism in the prior art, so that the measurement reference surface and the feature surface of the special-shaped part can be quickly aligned, improving the detection accuracy and efficiency. Compared with the traditional detection device, the scheme of the application is more flexible and stable during the fixing and measuring process, avoiding the deviation problem caused by vibration, and is suitable for detecting parts of various complex shapes.

[0066] The technical scheme of the size measuring assembly can effectively realize accurate detection of the space size of the part by arranging the size detector 7 on the mounting seat 6 and arranging the detection probe 71 on the detection end. The arm of the mounting seat 6 is provided with a bushing, the push rod 61 is slidably connected in the bushing, and the push rod 61 is fixedly connected with the mounting seat 6. This design ensures that the detection probe 71 can remain stable during detection, avoiding measurement errors caused by vibration or other factors. Specifically, the size detector 7 can adopt a high-precision laser range finder or a contact-type measurement probe, and through contact or non-contact measurement of the detection probe 71 with the surface of the part, high-precision detection of the complex curved surface and asymmetric structure of the part can be realized.

[0067] Further, the push rod 61 can be made of high-strength alloy material to ensure its durability and stability during use. The sliding fit between the bushing and the push rod 61 can be achieved through high-precision machining process to reduce friction and wear, and to ensure the smoothness and accuracy of the push rod 61 during sliding. The connection between the mounting seat 6 and the size detector 7 can be screw connection or buckle connection to facilitate the installation and removal of the size detector 7, and to improve the maintenance and use convenience of the device.

[0068] The present application realizes high-precision detection of the space size of the part by arranging the size detector 7 and the detection probe 71 on the mounting seat 6 and through the sliding fit design of the bushing and the push rod 61. Compared with the prior art, the technical scheme of the present application can effectively solve the problems of unstable fixation, large measurement error and complicated operation of the traditional detection device, and improve the detection precision and efficiency. Therefore, the present application provides an aluminum alloy special-shaped part space size detection device which is simple in structure, convenient to operate and high in measurement precision, and has wide application prospect.

[0069] The vertical guide rail 5 is rotationally connected with a screw rod 51, the screw rod 51 is threadedly connected with a C-shaped fixing frame 501, and the screw rod 51 is fixedly connected with a rotating cap 52 at the upper end.

[0070] The technical scheme adjusts the position of the C-shaped fixing frame 501 on the vertical guide rail 5 by rotating the connecting screw rod 51 and screwing the screw rod 51 with the C-shaped fixing frame 501. The rotating cap 52 is fixedly connected to the upper end of the screw rod 51. By rotating the screw rod 51, the C-shaped fixing frame 501 can move up and down along the vertical guide rail 5, thereby adjusting the position of the size measurement assembly. This design enables the detection device to adapt to parts of different heights, improving the flexibility and applicability of detection.

[0071] Further, the rotation of the screw rod 51 can be realized by manual or electric means. For example, the manual means can be operated by rotating the cap 52, and the electric means can drive the screw rod 51 to rotate by connecting a motor. Regardless of the method, accurate adjustment of the C-shaped fixing frame 501 can be realized to ensure the stability and accuracy of the measurement process.

[0072] The technical scheme of the present application realizes flexible adjustment of the position of the C-shaped fixing frame 501 by cooperation of the vertical guide rail 5, the screw rod 51 and the rotating cap 52. Compared with the manual lifting method in the prior art, the present application is more convenient and accurate to operate, effectively solves the problem of difficult vertical adjustment in the prior art, and improves the practicality and operation efficiency of the detection device.

[0074] The present application realizes stable fixation of the mounting seat 6 by slidingly connecting at least two groups of limiting rods 62 to one of the arms of the C-shaped fixing frame 501, and the limiting rods 62 are fixedly connected to the mounting seat 6. This design can effectively prevent the mounting seat 6 from shifting during detection, thereby improving the accuracy of detection. At the same time, the sliding connection of the limiting rods 62 allows the mounting seat 6 to be fine-tuned as needed, further ensuring the accuracy of measurement.

[0075] The limiting rods 62 can be made of high-strength materials such as stainless steel or alloy steel to ensure sufficient strength and durability during use. The sliding connection of the limiting rods 62 can be realized by guide rails or sliding blocks to ensure smoothness and stability of sliding. In addition, a locking device can be provided at the connection of the limiting rods 62 to prevent loosening during use.

[0076] Through the above design, the present application solves the problem that the mounting seat 6 of the traditional detection device is prone to shifting during detection, improving the stability and accuracy of detection. Compared with the prior art, the design of the present application is more simple and efficient, reducing the complexity and cost of the equipment, while improving the reliability and accuracy of detection.

[0077] The arc-shaped grooves 31 are arranged in a rotationally symmetrical manner, and the front and rear ends of adjacent two arc-shaped grooves 31 are located on the same radius line of the fixing seat 3.

[0078] This structure design makes the fixing assembly more evenly distributed around the fixing seat 3, so that it can better adapt to complex part shapes, especially those with radial distribution characteristics or spatially twisted structures. Through this rotationally symmetrical arc-shaped groove 31 layout, the fixing assembly can provide stable support and fixation in different directions, avoiding the micro-deformation problem caused by unstable clamping or local stress concentration in traditional clamping methods.

[0079] In specific implementation, the number and layout of the arc-shaped grooves 31 can be adjusted according to actual needs, such as the size and shape of the part to determine the number and distribution of the arc-shaped grooves 31. By reasonably designing the arc and position of the arc-shaped grooves 31, it can ensure that the fixing assembly is always in the best working state during clamping, thereby improving the accuracy and stability of detection.

[0080] This design solves the problem that the traditional detection device cannot adapt to the clamping needs of multi-directional irregular profiles, avoiding the micro-deformation problem caused by unstable clamping or local stress concentration. Further, through the rotationally symmetrical arc-shaped groove 31 layout, the fixing assembly can provide stable support in multiple directions, ensuring the stability of the part during detection and the accuracy of measurement.
