Description

TECHNICAL FIELD

[0001] The utility model relates to detection technical field, specifically, relate to a special-shaped workpiece positioning detection probe. BACKGROUND

[0002] In the field of shaft parts processing and detection, due to the unique arc part and plane part alternately existing structure of special-shaped shaft parts, it brings significant problems to accurate positioning and quality control work. The device or probe used for traditional shaft part positioning detection is often single in design and poor in universality, which is difficult to effectively cope with the complex and variable shape characteristics of special-shaped shaft parts.

[0003] Most conventional positioning detection equipment is based on fixed structure mode, and the detection element lacks flexible adjustment capability. In the face of the diversity of the shape and size of special-shaped shaft parts, it is difficult to realize close and stable abutment positioning. For example, when the size of the plane part has a slight deviation, and the shape is not standard flat, the traditional probe often causes positioning deviation because it cannot flexibly change its position according to the actual situation, thereby affecting the subsequent processing precision and detection result accuracy. At the same time, in actual production, different industries such as aerospace and automobile manufacturing have great differences in shaft part specifications (including diameter and length) and quality requirements. The aerospace field pursues extreme precision, and the control of shaft part flatness error is extremely strict. The traditional detection method is difficult to realize real-time and accurate monitoring of key quality indicators such as plane flatness. Once there is an out-of-tolerance situation, it is difficult to detect and adjust in time, resulting in high scrap rate, causing resource waste and delaying production progress. SUMMARY

[0004] The utility model provides a special-shaped workpiece positioning detection probe, solve the problem of poor detection effect and single function of special-shaped workpiece positioning probe in relevant technology.

[0005] The technical scheme of the utility model is as follows:

[0007] A mounting frame has a first mounting part and a second mounting part,

[0008] A detection part is two, two detection parts are respectively arranged on the first mounting part and the second mounting part, and two detection parts are respectively arranged on the first mounting part and the second mounting part.

[0009] The first mounting part and the first mounting part form a V-shaped space, and the V-shaped space is used for accommodating the shaft part.

[0012] a positioning member, which is arranged on the sealing member and penetrates the sliding slot, has a clamping groove, and the clamping groove is arranged in a plurality of circumferential rows,

[0013] a locking member, which is slidingly arranged on the mounting frame, has a clamping portion, and the clamping groove is used for accommodating the clamping portion.

[0014] As a further technical scheme, one end of the clamping groove has a fixing portion, the clamping portion is an elastic clamping portion, and after the locking member is slid, the fixing portion is clamped into the clamping groove.

[0015] As a further technical scheme, the detection member further comprises:

[0016] a detection tube, which is arranged in the mounting cavity and located at one side of the through hole, has an air outlet,

[0017] a blocking member, which is slidingly arranged in the detection tube and blocks or unblocks the air outlet after sliding,

[0018] a resilient member, which is arranged at one end on an inner wall of the mounting cavity and at the other end on the blocking member, and provides a force for blocking the air outlet by the blocking member.

[0019] As a further technical scheme, the blocking member has a closed portion, a spherical abutting portion, an annular groove, and a gas guide groove, the spherical abutting portion and the closed portion are respectively located at two ends of the blocking member, the resilient member acts on the closed portion, the annular groove is located at a middle portion of the blocking member, the gas guide groove is in communication with the annular groove, the gas guide groove penetrates the spherical abutting portion and is directed to the air outlet.

[0020] As a further technical scheme, the detection member further comprises:

[0021] a gas pipe, which is directed to the mounting cavity and is used for introducing pressure gas into the mounting cavity,

[0022] a flow rate sensor, which is arranged on the gas pipe and is used for detecting a flow rate of gas in the gas pipe,

[0023] an alarm, which is arranged on the mounting frame and is used for alarming when the flow rate of gas in the gas pipe is relatively large.

[0024] The working principle and beneficial effects of the utility model are as follows:

[0025] In the utility model, in the embodiment, two detection pieces are respectively slidingly and rotatably arranged on the first mounting portion and the second mounting portion of the mounting rack, and are used for abutting against the adjacent two plane portions.

[0028] The V-shaped space formed between the first mounting portion and the second mounting portion is used for accommodating the shaft parts, and this design of V-shaped space can well adapt to shaft parts of different diameters and lengths. For shaft parts with smaller diameters, the V-shaped space can provide sufficient accommodation space, so that they can be stably placed therein; for shaft parts with larger diameters, the opening shape and size of the V-shaped space can also be adapted by appropriate adjustment of the mounting rack, such as changing the distance between the mounting portions, to ensure that the shaft parts can be smoothly entered and accurately detected and positioned. For example, in the production of automobile parts, shaft parts of different specifications need to be processed, including small-diameter transmission shafts and large-diameter crankshafts, and the device can easily cope with these different specifications of parts thanks to the adaptability of the V-shaped space, which widens the application range of the device and enables it to meet the needs of shaft part processing in different industries.

[0038] Reference Figs. 1-3 For the first embodiment of the utility model, a special-shaped workpiece positioning detection probe is proposed, which is used for positioning detection of special-shaped shaft parts 1. The shaft parts 1 have arc-shaped parts 101 and plane parts 102, and the arc-shaped parts 101 and the plane parts 102 are alternately arranged. It comprises a mounting frame 11, the mounting frame 11 has a first mounting part 1101 and a second mounting part 1102, two detection pieces 12 are arranged on the first mounting part 1101 and the second mounting part 1102 respectively, and the two detection pieces 12 are respectively in sliding and rotating connection with the adjacent two plane parts 102. The first mounting part 1101 and the first mounting part 1101 form a V-shaped space 1103, and the V-shaped space 1103 is used for accommodating the shaft parts 1.

[0039] In this embodiment, two detection pieces 12 are respectively slidingly and rotatably arranged on the first mounting part 1101 and the second mounting part 1102 of the mounting frame 11, and are used for abutting with the adjacent two plane parts 102. This multi-directional abutting mode positions the shaft parts 1 from different angles, forming a more stable positioning system. At the same time, the sliding and rotating arrangement characteristics of the detection piece 12 make it better adapt to shaft parts 1 of different shapes and sizes. For some plane parts 102 with special shape or size deviation, the detection piece 12 can adjust its position by sliding and rotating to realize close abutment with the plane part 102, further enhancing the adaptability of the device to special-shaped workpieces and ensuring the accuracy and stability of positioning.

[0040] The detection pieces 12 are not only used for positioning, but also have detection functions. When in contact with the flat part 102, they can monitor in real time whether the shaft part 1 is in place and can monitor the surface quality of the shaft part 1. In the process of machining, it is crucial to judge whether the shaft part 1 meets the quality requirements. When producing high-precision shaft parts 1 for the aerospace field, the flatness requirement of the parts is extremely high, and the error needs to be controlled within a very small range. The detection pieces 12 can measure and feedback the flatness information of the flat part 102, and once the deviation exceeds the allowed range, the processing technology can be adjusted in time or the parts can be repaired, so as to ensure that the quality of the produced shaft parts 1 completely meets the high-standard requirements, reduces the scrap rate, and improves the product qualification rate.

[0041] The mounting frame 11 has a first mounting part 1101 and a second mounting part 1102. By reasonably distributing the settings of the detection pieces 12 on the two mounting parts, the space utilization is further optimized. The two detection pieces 12 slide and rotate on different mounting parts and do not interfere with each other, and can effectively position and detect the shaft part 1 in a limited space, so that the device realizes the maximization of space utilization while ensuring the integrity of the functions.

[0042] The V-shaped space 1103 formed between the first mounting part 1101 and the second mounting part 1102 is used to accommodate the shaft part 1. This design of V-shaped space 1103 can well adapt to shaft parts 1 of different diameters and lengths. For shaft parts 1 with smaller diameters, the V-shaped space 1103 can provide sufficient accommodation space so that they can be stably placed therein; for shaft parts 1 with larger diameters, the opening shape and size of the V-shaped space 1103 can also be adapted by appropriate adjustment of the mounting frame 11, such as changing the distance between the mounting parts, to ensure that the shaft part 1 can smoothly enter and be accurately detected and positioned. For example, in the production of automobile parts, shaft parts 1 of different specifications need to be machined, including small-diameter transmission shafts and large-diameter crankshafts, etc. The device can easily cope with these different specifications of parts thanks to the adaptability of the V-shaped space 1103, which widens the application range of the device and enables it to meet the needs of shaft part 1 machining in different industries.

[0043] Further, the mounting frame 11 has a sliding groove 1104, the detection piece 12 includes a sealing piece 1201, the sealing piece 1201 is rotationally and slidingly arranged in the sliding groove 1104, the sealing piece 1201 has a mounting cavity 1202, the mounting cavity 1202 has a through hole 1203, the through hole 1203 faces the flat part 102, a positioning piece 1204 is arranged on the sealing piece 1201 and penetrates the sliding groove 1104, the positioning piece 1204 has a clamping groove 1205, the clamping groove 1205 is arranged in a plurality of circumferential rows, a locking piece 1206 is slidingly arranged on the mounting frame 11, the locking piece 1206 has a clamping part, and the clamping groove 1205 is used to accommodate the clamping part.

[0044] In this embodiment, the sealing member 1201 is rotatably and slidably arranged in the sliding groove 1104, and the through hole 1203 of the mounting cavity 1202 of the sealing member 1201 faces the flat portion 102. This design can form a relatively sealed environment during detection, thereby reducing the interference of external factors on detection. The positioning member 1204 is arranged on the sealing member 1201 and penetrates the sliding groove 1104. When abutting against the flat portion 102, the positioning member 1204 can accurately determine the position of the shaft part 1, thereby providing an accurate reference for subsequent detection. The clamping grooves 1205 of the positioning member 1204 are arranged in a plurality of circles. This design increases the flexibility and accuracy of positioning. Different positions of the clamping grooves 1205 can correspond to different positioning requirements. When fine positioning of the shaft part 1 is required, the positioning member 1204 can be abutted against the flat portion 102 more accurately by selecting a suitable clamping groove 1205, thereby further improving the positioning accuracy and laying a solid foundation for subsequent machining or detection operations.

[0045] The locking member 1206 is elastically clamped with the clamping groove 1205 of the positioning member 1204. After sliding, the fixing portion 1207 of the locking member 1206 is clamped into the clamping groove 1205, thereby stably locking the positioning member 1204. During machining, the shaft part 1 can be subjected to external forces such as cutting force and vibration. The locking effect of the locking member 1206 can ensure that the positioning member 1204 always remains in an accurate positioning position and will not be displaced due to external interference. For example, during grinding of the shaft part 1, the vibration generated by grinding is large. However, since the positioning member 1204 is firmly locked by the locking member 1206, the positioning state of the shaft part 1 is maintained, the machining accuracy is ensured, the waste rate is reduced, and the qualified rate of products is improved.

[0046] Further, the locking member 1206 has a fixing portion 1207 at one end, and the clamping portion is an elastic clamping portion. After sliding, the fixing portion 1207 of the locking member 1206 is clamped into the clamping groove 1205.

[0047] In this embodiment, the rotation and sliding arrangement of the sealing member 1201 and the adjustability of the positioning member 1204 enable the device to easily adapt to shaft parts 1 of different specifications and shapes. When encountering flat portions 102 of different sizes, the relative position of the sealing member 1201 and the flat portion 1202 can be changed by rotating and sliding the sealing member 1201. In combination with the selection of the positioning member 1204 in different clamping grooves 1205, the shaft part 1 can be quickly and accurately positioned. For example, in the production of automobile parts, shaft parts 1 of various models need to be machined, and the sizes and shapes of the flat portions 102 thereof are different. The device can complete the positioning preparation work of different parts in a short time by flexible operation of the sealing member 1201 and the positioning member 1204, thereby improving the production efficiency and meeting the diversified production requirements.

[0048] In addition, when the shaft part 1 is detected or processed locally, the sealing member 1201 and the positioning member 1204 can be adjusted to achieve accurate positioning and detection of specific parts, further expanding the application range of the device and making it better adapt to different processing requirements.

[0049] The locking member 1206 is relatively simple to operate. When the positioning member 1204 needs to be locked, the locking member 1206 is simply slid so that the fixed part 1207 of the elastic clamping part is clamped into the clamping groove 1205 to complete the locking. When unlocking is needed, the fixed part 1207 is removed from the clamping groove 1205 by applying appropriate external force. This simple locking and unlocking operation does not require the operator to have high professional skills, reducing the training cost of the operator.

[0050] Further, the detection member 12 further comprises a detection tube 1208, which is arranged in the mounting cavity 1202 and located on one side of the through hole 1203. The detection tube 1208 has a gas outlet 1218. A sealing member 1209 is slidably arranged in the detection tube 1208 and blocks or unblocks the gas outlet 1218 after sliding. An elastic member 1210 is arranged on one side of the mounting cavity 1202 and on the other side of the sealing member 1209, providing a force for the sealing member 1209 to block the gas outlet 1218.

[0051] In this embodiment, the detection tube 1208 is arranged in the mounting cavity 1202 and located on one side of the through hole 1203. It has a gas outlet 1218 and can be used to spray gas to the surface of the shaft part 1 to assist in detection. For example, when detecting whether the shaft part 1 is in place, the shaft part 1 pushes the sealing member 1209 to open the gas outlet 1218. At this time, a specific gas such as clean compressed air can be sprayed through the detection tube 1208. Whether the gas is sprayed from the gas outlet 1218 determines whether the workpiece is in place. The sealing member 1209 slides in the detection tube 1208 to block or unblock the gas outlet 1218, achieving precise control of gas spraying. The elastic member 1210 provides a force for the sealing member 1209 to block the gas outlet 1218, ensuring that the gas outlet 1218 can be reliably blocked when gas spraying is not needed, preventing gas leakage and foreign matter from entering the detection tube 1208. This synergistic effect makes the detection process more accurate and controllable, and can improve the detection accuracy to a higher level.

[0052] When detecting whether the shaft part 1 is in place, the gas injection can be controlled by the pushing state of the shaft part 1 on the blocking piece 1209. The reliable blocking and accurate control of the blocking piece 1209 on the gas outlet 1218 of the detection tube 1208 ensure the stability of the gas supply. After the detection is completed, if the gas outlet 1218 cannot be effectively blocked or the opening degree control is inaccurate, it may cause unstable gas supply, affecting the accuracy of the detection result and the continuity of the detection process. For example, when a batch of shaft parts 1 are continuously detected, stable gas injection is needed to obtain consistent detection data. Through the accurate control of the blocking piece 1209, the flow, pressure and other parameters of the gas injected from the detection tube 1208 can be kept stable during each detection, making the detection result more comparable and reliable, ensuring the smooth progress of the detection work and improving the production efficiency.

[0053] At the same time, the presence of the elastic piece 1210 further enhances the reliability of the blocking piece 1209 blocking the gas outlet 1218. Even in the case of vibration, external force impact and other situations, the elastic piece 1210 can continuously exert force to keep the blocking piece 1209 in the blocking state, preventing the gas outlet 1218 from opening accidentally and avoiding gas leakage and other problems, maintaining the normal operating state of the device, reducing the number of detection failures and re-detection caused by abnormal gas supply, reducing production costs and improving the reliability of the device.

[0054] When the shaft part 1 is positioned and detected, if the detection piece 12 continuously alarms, the shaft part 1 can be manually adjusted to the positioning position. At this time, the detection tube 1208 plays an important role in quality detection. When the detection tube 1208 continuously leaks, this phenomenon can directly reflect the surface machining precision of the shaft part 1. If the surface machining precision of the part is high, the surface flatness and roughness meet the requirements, and the gas outlet hole of the detection tube 1208 cannot leak, and there will be no obvious continuous leakage. On the contrary, if there is continuous leakage, it is likely that the part surface has protrusions, depressions, roughness out-of-tolerance, etc., causing the gas to be unable to be blocked. In the scene of high-precision machining, the surface machining precision of some shaft parts used in the field of aerospace is extremely high, and even a small surface defect may affect the performance of the entire component. Through this leakage detection method of the detection tube 1208, it can quickly and accurately find out whether the part surface meets the precision requirements, providing a strong basis for subsequent processing decisions.

[0055] Moreover, this detection through the detection tube 1208 is carried out simultaneously in the positioning detection stage without the need for additional complex detection procedures. Compared with traditional post-sampling detection methods, it can timely find problems during the machining process, avoiding unnecessary machining of parts with precision problems in subsequent machining processes, greatly improving the machining efficiency and reducing resource waste.

[0056] In the traditional machining process of shaft parts, if there is no such real-time quality detection means, the final quality detection is often carried out after a series of machining processes are completed. Once it is found that the quality of the part does not meet the requirements, a large amount of processing time, manpower, material resources and other resources invested before will be wasted, and the unqualified parts need to be reworked or scrapped. By using the detection tube 1208 for quality detection in the positioning detection stage, when it is found that continuous air leakage indicates that the surface machining precision of the part is poor, the subsequent meaningless machining of the part can be stopped in time, and the machining resources can be transferred to other qualified parts or new machining tasks. For example, in a workshop for batch production of shaft parts, if there is no such early detection mechanism, a large number of parts may not be qualified until after going through multiple machining processes, resulting in low efficiency of the entire production process and a substantial increase in production cost. However, with the detection of the detection tube 1208, such a situation can be effectively avoided, and the utilization efficiency of production resources is improved.

[0057] In addition, timely stopping of meaningless machining can also reduce unnecessary wear and tear of the machining equipment. Because continuing to machine parts with unqualified quality cannot obtain qualified products, and the machining equipment will be additionally worn and torn in the invalid machining process, shortening the service life of the equipment. Through the quality detection of the detection tube 1208, the machining equipment can be protected, the equipment maintenance cost can be reduced, and the production cost can be further saved.

[0058] The use of the detection tube 1208 to realize the quality detection of the shaft part 1 makes the entire production process more optimized. It advances the quality detection link to the positioning detection stage, realizes the organic combination of machining and detection, and makes the production process more compact and efficient. In terms of production management of enterprises, this method helps to better arrange production plans, adjust the allocation of machining tasks in time according to the detection results, and ensure that resources are reasonably utilized.

[0059] Further, the plugging piece 1209 has a closed portion 1211, a spherical abutting portion 1212, an annular groove 1213 and a gas guide groove 1214, the spherical abutting portion 1212 and the closed portion 1211 are located at two ends of the plugging piece 1209 respectively, the elastic piece 1210 acts on the closed portion 1211, the annular groove 1213 is located in the middle of the plugging piece 1209, the gas guide groove 1214 communicates with the annular groove 1213, the gas guide groove 1214 penetrates through the spherical abutting portion 1212 and leads to the gas outlet 1218.

[0060] In this embodiment, the closing part 1211 of the blocking piece 1209 can reliably block the gas outlet 1218 of the detection tube 1208 under the action of the elastic piece 1210. This design ensures that the gas outlet 1218 can be tightly blocked when gas detection is not needed, effectively preventing gas leakage and external impurities from entering the detection tube 1208 through the gas outlet 1218 and affecting the internal device. At the same time, through the action of the elastic piece 1210 on the closing part 1211, the blocking control of the gas outlet 1218 is more accurate.

[0061] The gas guide groove 1214 on the blocking piece 1209 communicates with the annular groove 1213 and penetrates the spherical abutting part 1212 to the gas outlet 1218. This unique structure design provides a flexible conduction path for gas detection. When gas detection is needed, the gas can smoothly flow to the gas outlet 1218 through the gas guide groove 1214 and the annular groove 1213, and then be sprayed to the surface of the shaft part 1 for detection. Through the existence of the annular groove 1213, the gas can be buffered and distributed to a certain extent, making it more uniform and stable in the process of flowing to the gas outlet 1218, so as to better adapt to different detection scenes. The penetration design of the gas guide groove 1214 enables the gas to flow to the gas outlet 1218 in a more direct path, reducing the resistance of the gas inside the blocking piece 1209 and improving the flow efficiency of the gas. This is particularly important for scenarios that require rapid acquisition of detection results, as it can speed up detection and improve production efficiency. At the same time, by adjusting the sliding position of the blocking piece 1209 in the detection tube 1208, the relative positional relationship between the gas guide groove 1214 and the gas outlet 1218 can be further changed, thereby realizing precise control of the gas spraying direction and angle, meeting more delicate detection needs, and further improving the detection flexibility and precision of the device.

[0062] When the blocking piece 1209 abuts against the shaft part 1, the spherical abutting part 1212 plays a crucial role. Its round and spherical design makes the contact with the outer surface of the shaft part 1 a point contact or a small-area curved surface contact, which is much softer than other possible sharp or flat contact modes. In the positioning detection process of the shaft part 1, especially when the blocking piece 1209 is needed to assist in judging the positioning of the part, the blocking piece 1209 will frequently interact with the surface of the shaft part 1. The presence of the spherical abutting part 1212 ensures that no scratches or wear and tear will occur on the outer surface of the shaft part 1 during these frequent contacts. This soft contact mode not only avoids wear and tear during a single abutment, but also ensures that the outer surface of the shaft part 1 remains in good condition even after multiple abutments between the blocking piece 1209 and the shaft part 1 during long-term detection operations. This is particularly important for production scenarios that require repeated positioning detection of a large number of shaft parts 1, as it effectively reduces the scrap rate of the parts caused by the detection process, improves the production qualification rate, saves production costs for the enterprise, and enhances economic benefits.

[0063] Further, the detection piece 12 further comprises an air pipe 1215 which is connected to the installation cavity 1202 and is used to introduce pressure gas into the installation cavity 1202. A flow rate sensor 1216 is arranged on the air pipe 1215 and is used to detect the flow rate of the gas in the air pipe 1215. An alarm 1217 is arranged on the mounting frame 11 and is used to alarm when the flow rate of the gas in the air pipe 1215 is too high.

[0064] In this embodiment, the flow rate sensor 1216 is arranged on the air pipe 1215 and can accurately detect the flow rate of the gas in the air pipe 1215 in real time. When the shaft part 1 is subjected to positioning detection or surface machining precision detection by the detection pipe 1208, the stability and specific value of the gas flow rate are crucial to the accuracy of the detection result. The presence of the flow rate sensor 1216 enables the operator to know the gas flow rate in real time. If the flow rate deviates from the pre-set reasonable range, the operator can determine the problems in the positioning and surface machining precision of the shaft part 1 in a timely manner, thereby improving the detection precision of the shaft part 1 and ensuring that the product quality meets the high standard requirements.

[0065] When the gas flow rate in the gas pipe 1215 is large, the alarm 1217 will issue a warning. This abnormal alarm mechanism is of great significance to ensure the smooth progress of the detection process. In actual detection operations, sudden changes in gas flow rate may be caused by factors such as mispositioning of the shaft part 1, insufficient machining accuracy of the shaft part 1, faults in the gas supply equipment, blockage or leakage of the gas pipe 1215, and abnormalities in the sealing element 1209 in the detection pipe 1208. If such a situation occurs and is not promptly discovered and addressed, it will not only affect the accuracy of the detection results of the current shaft part 1, but also may cause damage to the device itself, such as excessive gas flow rate that may impact the detection pipe 1208 and its internal components, leading to problems such as wear and deformation. The alarm 1217 can issue a warning at the first time of abnormal gas flow rate, reminding the operator to promptly investigate the problem and take appropriate measures such as checking the gas supply equipment, checking whether the connection of the gas pipe 1215 is normal, checking the state of the sealing element 1209, etc., to ensure that the detection process can continue to proceed normally, avoid the negative consequences of a large amount of invalid detection data due to failure to promptly discover the problem, increase the maintenance cost of the device, and improve the reliability and detection efficiency of the device.

[0066] The cooperation of the flow rate sensor 1216 and the alarm 1217 provides a strong guarantee for stable gas supply of the device. During the entire detection process of the shaft part 1, continuous and stable gas supply to the detection pipe 1208 is required to achieve accurate detection function. The flow rate sensor 1216 monitors the gas flow rate in real time, and once it finds fluctuations or abnormal changes in the flow rate, the alarm 1217 will respond in time and issue a warning. The operator can quickly take measures to adjust the gas supply according to the warning prompt to ensure that the gas flow rate remains within the appropriate range, thereby maintaining the stability of the detection process. For example, when a batch of shaft parts 1 is being continuously detected, stable gas supply is crucial for obtaining consistent and reliable detection data. Through the cooperation of the flow rate sensor 1216 and the alarm 1217, deviations in detection results caused by unstable gas flow rate can be effectively avoided, ensuring the smooth progress of the detection work and improving production efficiency.
