Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and specifically relates to an automatic detection mechanism for sleeves. Background Technology

[0002] In mechanical manufacturing, sleeves are commonly used structural components, typically hollow cylindrical parts used to support shaft components, guide movement, or serve as positioning elements. Common sleeve structures include, but are not limited to, features such as a centrally located conical hole. The machining accuracy of the conical hole directly impacts subsequent assembly quality and equipment operational stability, thus imposing high requirements on its geometric dimensions and surface quality.

[0003] In actual production, to ensure that the finished casing meets design and usage requirements, its key dimensions must be rigorously inspected. In particular, parameters such as the taper and diameter of the conical bore directly affect assembly accuracy and fit performance.

[0004] However, current technologies for inspecting bushings, especially those with tapered bores, still primarily rely on manual operation. Methods include plug gauge measurement, optical projector comparison, or coordinate measuring machine sampling. These traditional inspection methods have the following shortcomings:

[0005] The detection efficiency is low, and the detection time for a single workpiece is long, making it difficult to meet the needs of large-scale continuous operation in modern production lines.

[0006] Human error is significant, and the consistency and accuracy of test results are difficult to guarantee due to factors such as the operator's experience and visual judgment.

[0007] The detection accuracy is unstable, especially for complex structures such as conical holes. Traditional methods are difficult to achieve stable measurements with high precision and good repeatability. Utility Model Content

[0065] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0066] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0067] like Figure 1 and Figure 11 As shown, this solution provides an automatic inspection mechanism for sleeves. The sleeve 1 has a conical hole 2. The automatic inspection mechanism includes: an operating table 6; a feeding unit 7 located on the side of the operating table 6; a conveying unit 8 disposed on the operating table 6 for conveying the sleeve 1; a first inspection unit 9 disposed on the operating table 6 for inspecting the outer diameter of the sleeve 1; a second inspection unit 10 disposed on the operating table 6, having a movable inspection rod 11 and a pressure block 12. When the inspection rod 11 is movably inserted into the conical hole 2, it is used to inspect the conical hole 2. The pressure block 12 movably abuts against one end of the sleeve 1 to fix the sleeve 1 on the operating table 6; a third inspection unit 13 disposed on the operating table 6 for visual inspection of the sleeve 1; and a sorting unit 14 disposed on one side of the operating table 6 for sorting the inspected sleeves 1.

[0068] During operation, the feeding unit 7 transports the sleeve 1 to be inspected to a preset position, whereupon the conveying unit 8 picks it up and transports it to the location of the first inspection unit 9. The first inspection unit 9 measures the outer diameter of the sleeve 1 to ensure that its dimensions meet the standard. After the outer diameter inspection is completed, the conveying unit 8 transports the sleeve 1 to the location of the second inspection unit 10. At this time, the inspection rod 11 is located below the sleeve 1, and the pressure block 12 is located above the sleeve 1. The inspection rod 11 is inserted axially into the conical hole 2 from the lower end of the sleeve 1, and the inspection can be performed during the initial insertion process. The sleeve 1 is positioned and guided to ensure it maintains a stable posture during subsequent testing. Simultaneously, the pressure block 12 rotates and moves downwards until it contacts one end of the sleeve 1 and applies appropriate clamping force, thus firmly fixing the sleeve 1 in the testing position and preventing displacement due to vibration or uneven force during testing. Subsequently, the testing rod 11 continues to penetrate into the conical hole 2, and, in accordance with pre-set standards, performs precise measurements on the conical hole 2. After testing is completed, the testing rod 11 and pressure block 12 synchronously reset, releasing the sleeve 1; the transport unit 8 then grabs it again. The sleeve 1 is transported to the location of the third inspection unit 13; the third inspection unit 13 performs visual inspection on the sleeve 1; finally, the transport unit 8 transports the sleeve 1, which has completed all inspection tasks, to the sorting unit 14; the sorting unit 14 sorts the sleeve 1 according to the data information fed back by each inspection unit; during the inspection of the conical hole 2, the coordinated action of the inspection rod 11 and the pressure block 12 is an important link to ensure the inspection accuracy and stability; the inspection rod 11 is not only used to realize the insertion measurement of the conical hole 2, but also plays a positioning role in the inspection process; the pressure block 12 achieves stable clamping of the workpiece without damaging the surface of the sleeve 1 through the optimized clamping force distribution; compared with the traditional manual inspection method, the automatic inspection mechanism in this solution greatly improves the inspection accuracy and repeatability, especially suitable for high-precision measurement of complex structures such as the conical hole 2; it not only greatly improves the inspection accuracy and repeatability, but also has high inspection efficiency and good result consistency, which can meet the high efficiency and stability requirements of quality control in the mass production environment of modern manufacturing.

[0069] In order to provide stable support for the sleeve 1 during the testing process, a support platform 15 is also provided on the operating table 6. The support platform 15 is used to support the sleeve 1 to be tested. The support platform 15 is provided with a through hole 16 corresponding to the position of the testing rod 11. The testing rod 11 is located below the support platform 15 and can be inserted into the conical hole 2 of the sleeve 1 through the through hole 16 to achieve accurate testing of the conical hole 2.

[0070] Furthermore, the second detection unit 10 also includes: a first driving member 17, located below the support platform 15, with a support frame 18 at the output end of the first driving member 17, and a slider 19 slidably mounted on the support frame 18, one end of the detection rod 11 inserted into the slider 19, the first driving member 17 driving the detection rod 11 to rise and fall via the support frame 18; an elastic member 20, one end of which abuts against the support frame 18, and the other end against the slider 19; a first measuring member 21, mounted on the support frame 18, with a lifting rod 22 at the sensing end of the first measuring member 21, the end of the lifting rod 22 away from the first measuring member 21 inserted into the slider 19 and abutting against the detection rod 11, the first measuring member 21 being used to measure the depth of the detection rod 11 inserted into the conical hole 2; and a second driving member 23, with the pressure block 12 connected to the output end of the second driving member 23, the second driving member 23 being used to drive the pressure block 12 to move.

[0071] During operation, when the conveying unit 8 transports the sleeve 1, whose outer diameter has been measured, to the testing position on the support platform 15 corresponding to the through hole 16, the testing rod 11 is located directly below the sleeve 1, and the pressure block 12 is located above the sleeve 1. Then, the first driving member 17 is activated, driving the support frame 18 to rise, so that the testing rod 11 passes through the through hole 16 and is inserted axially into the conical hole 2 from the lower end of the sleeve 1. At the same time, the second driving member 23 drives the pressure block 12 to rotate and descend until the pressure block 12 contacts the top of the sleeve 1 and applies an appropriate clamping force, thereby stabilizing and fixing the sleeve 1 in the testing position. The first driving member 17 continues to drive the support frame 18 to rise, driving the testing rod 11 to penetrate further into the conical hole 2. During the rising process, the support frame 18 applies pressure to the elastic member 20, causing it to compress and deform.

[0072] If the diameter of the conical hole 2 is acceptable, when the first driving member 17 drives the support frame 18 to the preset stroke end point, the detection rod 11 will just reach the set depth, and the data recorded by the first measuring member 21 at this time will meet the standard value. If the diameter of the conical hole 2 is too large, when the support frame 18 reaches the preset stroke end point, since the detection rod 11 has not been fully inserted into the conical hole 2, the elastic member 20 will recover its deformation, pushing the slider 19 to continue rising, driving the detection rod 11 to be further inserted into the hole. At the same time, the lifting rod 22 will be driven by the slider 19 to move upward relative to the first measuring member 21. This process is identified by the first measuring member 21 as exceeding the allowable range. If the diameter of the conical hole 2 is too small, during the rising process of the support frame 18, the detection rod 11 will be detected... Rod 11 contacts the inner wall of the conical hole 2 in advance and stops moving forward. At this time, slider 19 is subjected to a reaction force and moves downward. Elastic element 20 is further compressed, and lifting rod 22 is displaced downward relative to the first measuring element 21. The first measuring element 21 judges that the hole diameter does not meet the requirements. In summary, through the precise control of the first driving element 17, the buffer compensation mechanism of the elastic element 20, and the feedback detection of the first measuring element 21, high-precision detection of the size of the conical hole 2 is achieved. Among them, the first driving element 17 can be a motor, hydraulic cylinder, or pneumatic cylinder; the second driving element 23 is preferably a motor; the first measuring element 21 can be a measuring element such as an electronic ruler or sensor; and the elastic element 20 is preferably a spring.

[0073] Furthermore, the feeding unit 7 includes: a first conveyor belt 24, located on the side of the support platform 15, for transporting the sleeve 1 to be inspected; and an inspection element 25, which is disposed on the movement path of the sleeve 1 for detecting whether the sleeve 1 has moved to a preset position. The sleeve 1 can be placed on the first conveyor belt 24 by manual or automatic feeding device and transported to the preset position by the first conveyor belt 24. When the sleeve 1 reaches the preset position, the inspection element 25 inspects it to determine whether the sleeve 1 has been accurately positioned, thereby providing signal feedback for subsequent processes. The inspection element 25 is preferably a displacement sensor.

[0074] Furthermore, the conveying unit 8 includes: a pneumatic gripper 26, which is movably disposed above the operating table 6 for conveying the sleeve 1; a third drive member 27, the output end of which is connected to a first movable seat 28, the pneumatic gripper 26 being connected to the first movable seat 28, and the third drive member 27 driving the pneumatic gripper 26 to move vertically through the first movable seat 28; and a fourth drive member 29, the third drive member 27 being connected to the fourth drive member 29, and the fourth drive member 29 driving the third drive member 27 to move horizontally; the third drive member 27 and the fourth drive member 29 are arranged in a cross configuration, forming a two-dimensional conveying platform that can move collaboratively in both vertical and horizontal directions; wherein, the third drive member 27 can be a motor, a hydraulic cylinder, or a pneumatic cylinder, and the fourth drive member 29 is preferably a linear guide rail.

[0075] Furthermore, the sleeve 1 also has a frustum body 3, and the first detection unit 9 includes: a first clamping block 30, a second movable seat 31 is provided on the side of the support platform 15, and two opposing first clamping blocks 30 are provided on the second movable seat 31. The two first clamping blocks 30 respectively move against the upper sides of the frustum body 3 for detecting the outer diameter of the upper part of the frustum body 3; a fifth driving member 32 is provided on the second movable seat 31, and a first driving rod 33 is provided at the output end of the fifth driving member 32. The first driving rod 33 passes through the two first clamping blocks. On the sleeve 1, the fifth driving member 32 drives the two first clamping blocks 30 to move closer or further apart through the first driving rod 33; the second measuring member 34 has a first moving rod 35 at its sensing end, which passes between the two first clamping blocks 30, and the second measuring member 34 measures the distance between the two first clamping blocks 30 through the first moving rod 35; the sixth driving member 36 has a second moving seat 31 connected to it, and the sixth driving member 36 drives the two first clamping blocks 30 to move closer or further away from the sleeve 1 in the horizontal direction through the second moving seat 31.

[0076] During operation, the pneumatic gripper 26, driven by the third drive member 27 and the fourth drive member 29, transports the sleeve 1 to be tested, located at a preset position on the first conveyor belt 24, to the support platform 15 at the position corresponding to the first clamping block 30. Subsequently, the sixth drive member 36 is activated, driving the second moving seat 31 to move horizontally, so that the two first clamping blocks 30 approach the sleeve 1 and finally reach the set detection position. Then, the fifth drive member 32 is activated, pushing the two first clamping blocks 30 towards the center through the first drive rod 33 until they contact the two sides of the upper part of the frustum body 3. During this process, the first moving rod 35 moves synchronously with the first clamping blocks 30, and the second measuring member 34 calculates the distance between the two first clamping blocks 30 based on the displacement change of the first moving rod 35, thereby measuring the outer diameter of the upper part of the frustum body 3. By comparing this measured value with the standard value, it is determined whether it meets the outer diameter tolerance requirements, thus completing the automatic detection of the outer diameter. The fifth drive member 32 and the sixth drive member 36 can be a motor, a hydraulic cylinder, or a pneumatic cylinder.

[0077] Furthermore, the first detection unit 9 also includes: a second clamping block 37, a third movable seat 38 is provided on the side of the support platform 15, and two opposing second clamping blocks 37 are provided on the third movable seat 38. The first clamping block 30 is higher than the second clamping block 37 in the vertical direction. The two second clamping blocks 37 move and abut against the lower sides of the frustum body 3, respectively, for detecting the outer diameter of the lower part of the frustum body 3; and a seventh driving member 39, the output end of which is provided with a second driving rod 40, which passes through the two second clamping blocks 37. The seventh driving member 39 drives the two second clamping blocks 37 to move closer or further away from each other via the second driving rod 40; the third measuring member 41 has a second moving rod 42 at its sensing end, which passes through the two second clamping blocks 37, and the third measuring member 41 measures the distance between the two second clamping blocks 37 via the second moving rod 42; the eighth driving member 43 has a third moving seat 38 connected to it, and the eighth driving member 43 drives the second clamping blocks 37 to move closer or further away from the sleeve 1 in the horizontal direction via the third moving seat 38.

[0078] During operation, the pneumatic gripper 26, driven by the third drive unit 27 and the fourth drive unit 29, transports the sleeve 1, whose outer diameter of the upper part of the frustum body 3 has been measured, to the support platform 15 at the position corresponding to the second clamping block 37. Subsequently, the eighth drive unit 43 is activated, driving the third moving seat 38 to move horizontally, so that the two second clamping blocks 37 approach the sleeve 1 and finally reach the set measurement position. Then, the seventh drive unit 39 is activated, pushing the two second clamping blocks 37 towards the center through the second drive rod 40 until they are respectively aligned with the outer diameter of the frustum body 3. The two sides of the lower part of the platform body 3 contact and apply a certain clamping force; during this process, the second moving rod 42 moves synchronously with the second clamping block 37, and the third measuring element 41 calculates the distance between the two second clamping blocks 37 according to the displacement change of the second moving rod 42, thereby measuring the outer diameter of the lower part of the frustum body 3; by comparing the measured value with the standard value, it is determined whether the part meets the outer diameter tolerance requirements, thereby completing the automatic detection of the lower outer diameter of the sleeve 1; the seventh driving element 39 and the eighth driving element 43 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0079] Furthermore, the sleeve 1 also has a cylindrical hole 4 and an annular boss 5. The cylindrical hole 4 is connected to the conical hole 2, and the annular boss 5 is integrally formed with the frustum body 3. The third detection unit 13 includes: a first visual inspection element 44, which is located above the support platform 15 and is used to perform visual inspection on the cylindrical hole 4; and a second visual inspection element 45, which is located on the side of the support platform 15 and is used to perform visual inspection on the annular boss 5.

[0080] After the second detection unit 10 completes the detection of the conical hole 2, the transport unit 8 transports the sleeve 1 to the detection position on the support platform 15 corresponding to the third detection unit 13. At this time, the first visual inspection component 44 is located directly above the sleeve 1 and performs visual inspection on the diameter of the cylindrical hole 4. At the same time, the second visual inspection component 45 is located to the side of the sleeve 1 and measures the height and outer diameter of the annular boss 5 through visual inspection to determine whether it meets the design requirements. Both the first visual inspection component 44 and the second visual inspection component 45 can be industrial cameras or other visual inspection equipment.

[0081] Furthermore, the sorting unit 14 includes: a second conveyor belt 46, which is disposed on the side of the support platform 15 for receiving and transporting the sleeves 1 that have completed inspection; a first collector 47 and a second collector 48 are disposed opposite to each other on both sides of the second conveyor belt 46, the first collector 47 for receiving qualified sleeves 1 and the second collector 48 for receiving unqualified sleeves 1.

[0082] Furthermore, the sorting unit 14 also includes: a sorting plate 49, which is movably disposed on the moving path of the sleeve 1 for sorting the sleeve 1 on the second conveyor belt 46; and a ninth driving member 50, which is disposed on the first collecting member 47, and the sorting plate 49 is connected to the output end of the ninth driving member 50, the ninth driving member 50 being used to drive the sorting plate 49 to move.

[0083] During operation, the conveying unit 8 transports the sleeve 1, which has completed all inspection steps, to the second conveyor belt 46; the control system determines whether the sleeve 1 is qualified based on the inspection results fed back by each inspection unit, and controls the sorting action accordingly:

[0084] When the sleeve 1 is a qualified product, the ninth drive unit 50 first drives the material distribution plate 49 to move away from the first collection unit 47, so that it avoids the passage path of the qualified product; when the second conveyor belt 46 transports the qualified sleeve 1 to the feed end of the first collection unit 47, the ninth drive unit 50 starts again, drives the material distribution plate 49 to move closer to the first collection unit 47, and accurately pushes the qualified product into the first collection unit 47.

[0085] When the sleeve 1 is a defective product, the sorting plate 49 remains stationary on the side closest to the first collecting member 47; when the second conveyor belt 46 transports the defective sleeve 1 to the feed end of the second collecting member 48, the ninth driving member 50 is activated, driving the sorting plate 49 to move towards the second collecting member 48, pushing the defective sleeve 1 into the second collecting member 48; through the above structure and control method, the automatic sorting and classification collection of the sleeve 1 is realized, improving the automation level and detection efficiency of the equipment.

[0086] Furthermore, the second collecting component 48 is provided with at least one material channel 51. The number of material channels 51 can be set to two or three according to production needs, so as to classify and collect different types of non-conforming products, thereby improving the efficiency of subsequent processing. If the second collecting component 48 has multiple material channels 51, these material channels 51 are arranged side by side on the side of the second conveyor belt 46. When the second conveyor belt 46 transports the non-conforming sleeve 1 to the feed end of a certain material channel 51, the ninth driving component 50 drives the material distribution plate 49 to move, pushing the non-conforming products into the corresponding material channel 51, thereby realizing the refined classification and management of non-conforming products.
