Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, and in particular to a comprehensive inspection mechanism for the dimensions of can-shaped parts. Background Technology

[0002] Can-shaped or cylindrical workpieces are widely used in the mechanical field. Firstly, they can serve as raw materials for other types of workpieces. Secondly, they can be directly applied in bearing transmissions. For example, cylindrical bearing bushes, as the core component of radial sliding bearings, achieve sliding support through the inner surface mating with the journal; or flange-type sleeve bearings integrate thrust resistance, suitable for equipment such as hydraulic pumps; drum couplings use cylindrical intermediate connecting parts, absorbing vibration deviations through elastic bodies, adapting to shaft transmission systems; cylindrical workpieces are used in conjunction with flat keys to achieve circumferential fixation of shafts, gears, and pulleys, bearing shear forces and bending moments. All these applications require precise fit between the can-shaped workpieces and bearings, making the dimensions of the can-shaped workpieces extremely important.

[0003] Traditional dimensional inspection of can-shaped parts mainly relies on direct measurement methods, such as the two-point or three-point positioning method: using two-point or three-point positioning, the hole diameter is directly measured. Commonly used measuring tools include vernier calipers, inside micrometers, inside dial indicators, and dial gauges. Depending on the accuracy level, size, and quantity of the hole being measured, more specialized measuring tools can be selected, such as inside micrometers and electronic plug gauges. Lever mechanism hole measurement: commonly used in handheld hole measuring tools, such as inside dial indicators and inside micrometers. The difference between the measured hole diameter and the calibration ring gauge hole diameter is read from the dial indicator or micrometer through the lever mechanism. Wedge principle hole measurement: also commonly used in handheld hole measuring tools, such as inside dial indicators for measuring small holes. When the measured hole compresses the probe, causing the measuring rod with a cone to move, the hole diameter error can be read from the dial indicator or micrometer. While traditional inspection methods can meet measurement needs to a certain extent, they suffer from low efficiency and susceptibility to human factors.

[0004] Currently, there are also methods that use industrial cameras for high-precision visual inspection. However, these solutions are costly, and because industrial cameras require a certain height and focusing distance, they are difficult to insert into the interior of can-shaped parts. Different types of can-shaped parts may have different inner and outer diameters at different heights, making visual inspection difficult to adapt to the inspection of these can-shaped parts, resulting in inaccurate dimensional measurements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a comprehensive inspection mechanism for the dimensions of can-shaped parts, which solves the problems of low efficiency, susceptibility to human factors, or poor adaptability of industrial vision inspection methods to different types of can-shaped parts, resulting in inaccurate inspection.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a comprehensive detection mechanism for can-shaped parts, used to detect the inner and outer dimensions of can-shaped parts placed on a fixed base, the fixed base being disposed on top of a fixed support, comprising: In the vertical projection, the center of the can-shaped part coincides with the center of the fixed base; The system comprises a first detection component, a second detection component, and a sensing component. The first detection component is disposed on the side of a fixed bracket and has a first detection end. The first detection end extends into the fixed bracket through a detection opening and extends upward from the center of the fixed base into the interior of the can-shaped component. The first detection component drives the first detection end to move horizontally and / or vertically until it abuts against the inner wall of the can-shaped component. The second detection component is disposed on the fixed bracket and surrounds the fixed base. The second detection component has a second detection end on the side near the outer wall of the can-shaped component. The second detection component drives the second detection end to move horizontally and / or vertically until it abuts against the outer wall of the can-shaped component. Both the first and second detection components are equipped with sensing components for sensing the horizontal and / or vertical movement distance of the first or second detection end.

[0007] In one embodiment, the first detection component further includes a first support, a first horizontal cylinder, a first connecting slide, a first lifting cylinder, and a first lifting plate; the first support is fixedly connected to a fixed bracket, the fixed end of the first horizontal cylinder is disposed on the first support, the output end of the first horizontal cylinder is provided with a first connecting slide, the first horizontal cylinder pushes the first connecting slide to slide horizontally along the first support, the first lifting cylinder is disposed on the top of the first connecting slide, the first lifting plate is slidably connected to the side of the first connecting slide near the can-shaped component and driven by the first lifting cylinder, the first lifting cylinder drives the first lifting plate to move vertically along the first connecting slide, and the first detection end is connected to the first lifting plate; The second detection assembly also includes a second support, a second horizontal cylinder, and a second connecting slide. The second support is located on the top of the fixed bracket. The fixed end of the second horizontal cylinder is located on the second support. The output end of the second horizontal cylinder is provided with a second connecting slide. The second horizontal cylinder pushes the second connecting slide to slide horizontally along the second support. The second detection end is located on the side of the second connecting slide near the can-shaped part.

[0008] In one embodiment, the second detection component further includes a second lifting cylinder and a second lifting plate. The second lifting cylinder is disposed on the top of the second connecting slide. The second lifting plate is slidably connected to the side of the second connecting slide near the can-shaped component and is driven by the second lifting cylinder. The second lifting cylinder drives the second lifting plate to move vertically along the second connecting slide. The second detection end is connected to the second lifting plate.

[0009] In one embodiment, the sensing component includes a sensing bracket and a telescopic sensor. The sensing bracket has a clamping through hole corresponding to the telescopic sensor. The telescopic sensor is disposed in the clamping through hole, and the detection end of the telescopic sensor abuts against a first connecting slide or a second connecting slide.

[0010] In one embodiment, each of the first connecting slides or the second connecting slides abuts against two telescopic sensors, which are respectively disposed at the top or bottom of the first connecting slide or the second connecting slide.

[0011] In one embodiment, the sensing component further includes a displacement conductor disposed between the first or second lifting plate and the telescopic sensor, and / or, the displacement conductor disposed between the first or second connecting slide and the telescopic sensor.

[0012] In one embodiment, the sensing component further includes a direction conversion element, which is generally L-shaped. The middle part of the direction conversion element is hinged to the end of the first or second support away from the can-shaped component. The two ends of the direction conversion element abut against the telescopic sensor and the displacement transmission element, respectively. The telescopic sensor, the direction conversion element, and the displacement transmission element are in the same plane, and the displacement transmission element is perpendicular to the telescopic sensor.

[0013] In one embodiment, the first detection end includes a detection ball head, a connecting rod, and a connecting arm. The connecting arm is L-shaped, with one end connected to the first lifting plate and the other end connected to the detection ball head via the connecting rod.

[0014] In one embodiment, a pressure sensor is provided on the connecting rod.

[0015] In one embodiment, a pressure sensor is provided on the second detection end.

[0016] The beneficial effects of this utility model are as follows: Traditional methods for measuring the dimensions of can-shaped parts rely primarily on manual operation of measuring tools. While this can meet measurement needs to some extent, it suffers from low efficiency and susceptibility to human error, resulting in poor measurement accuracy. High-precision visual inspection, on the other hand, is not only more expensive but also has stricter requirements regarding the type of can-shaped part, exhibiting poor adaptability to workpieces with varying inner and outer diameters.

[0017] Therefore, the first detection component of this invention extends vertically upwards from the bottom of the can-shaped part along its center. A first detection end is provided at the end of the first detection component, which moves horizontally and / or vertically until it abuts against the inner wall of the can-shaped part. Simultaneously, the horizontal and / or vertical displacement of the first detection component is detected by a sensing component, thus obtaining the inner diameter of the can-shaped part at different heights. Furthermore, a second detection component is arranged around the outside of the can-shaped part. The horizontal and / or vertical movement of the second detection end on the second detection component allows the corresponding sensing component to obtain the outer diameter of the can-shaped part at different positions. Through the cooperation of the first and second detection components, the overall size of the can-shaped part can be obtained, making it convenient to use.

[0018] Furthermore, the first and second detection components move bidirectionally, and data acquisition is achieved by measuring the displacement distance through the sensing components, resulting in high data accuracy and precision. Attached Figure Description

[0024] Please refer to Figures 1 to 10 A comprehensive inspection mechanism for can-shaped parts is provided for inspecting the internal and external dimensions of can-shaped parts placed on a fixed base 2. The fixed base 2 is located on top of a fixed support 1 and includes: In the vertical projection, the center of the can-shaped part coincides with the center of the fixed base 2; The detection module includes a first detection component 3, a second detection component 4, and a sensing component 5. The first detection component 3 is disposed on the side of the fixed bracket 1 and has a first detection end 31. The first detection end 31 extends into the fixed bracket 1 through a detection opening and extends upward from the center of the fixed base 2 into the interior of the can-shaped component. The first detection component 3 drives the first detection end 31 to move horizontally and / or vertically until it abuts against the inner wall of the can-shaped component. The second detection component 4 is disposed on the fixed bracket 1 and surrounds the fixed base 2. The second detection component 4 has a second detection end 41 on the side near the outer wall of the can-shaped component. The second detection component 4 drives the second detection end 41 to move horizontally and / or vertically until it abuts against the outer wall of the can-shaped component. Both the first detection component 3 and the second detection component 4 are provided with sensing components 5, which are used to sense the horizontal and / or vertical movement distance of the first detection end 31 or the second detection end 41.

[0025] To ensure that the displacement of the first detection end 31 and the second detection end 41 does not deviate during the detection process, thereby ensuring the accuracy of the detection, in this embodiment, the first detection component 3 further includes a first support 32, a first horizontal cylinder 33, a first connecting slide 34, a first lifting cylinder 35, and a first lifting plate 36; the first support 32 is fixedly connected to the fixed bracket 1, the fixed end of the first horizontal cylinder 33 is set on the first support 32, the output end of the first horizontal cylinder 33 is provided with the first connecting slide 34, the first horizontal cylinder 33 pushes the first connecting slide 34 to slide horizontally along the first support 32, the first lifting cylinder 35 is set on the top of the first connecting slide 34, the first lifting plate 36 is slidably connected to the side of the first connecting slide 34 near the can-shaped part and driven by the first lifting cylinder 35, the first lifting cylinder 35 drives the first lifting plate 36 to move vertically along the first connecting slide 34, and the first detection end 31 is connected to the first lifting plate 36; The second detection assembly 4 also includes a second support 42, a second horizontal cylinder 43, and a second connecting slide 44. The second support 42 is mounted on the top of the fixed bracket 1. The fixed end of the second horizontal cylinder 43 is mounted on the second support 42, and the output end of the second horizontal cylinder 43 is provided with the second connecting slide 44. The second horizontal cylinder 43 pushes the second connecting slide 44 to slide horizontally along the second support 42. The second detection end 41 is located on the side of the second connecting slide 44 near the can-shaped part. This configuration, through the first connecting slide 34 and the first lifting plate 36 forming horizontal and vertical limits, ensures that the displacement of the first detection end 31 is entirely within a vertical plane, thereby guaranteeing the accuracy of the detection. The second connecting slide 44 allows the second detection end 41 to slide back and forth along a straight line, ensuring the stability of the overall structure and the accuracy of the detection.

[0026] In this embodiment, the second detection component 4 further includes a second lifting cylinder 45 and a second lifting plate 46. The second lifting cylinder 45 is disposed on the top of the second connecting slide 44. The second lifting plate 46 is slidably connected to the side of the second connecting slide 44 near the can-shaped component and is drivenly connected to the second lifting cylinder 45. The second lifting cylinder 45 drives the second lifting plate 46 to move vertically along the second connecting slide 44. The second detection end 41 is connected to the second lifting plate 46. After setting the second lifting cylinder 45 and the second lifting plate 46, the second detection end 41 can move vertically. Those skilled in the art can adjust it according to actual needs, without specific limitations.

[0027] In this embodiment, multiple second detection components 4 are provided, and the second detection ends 41 of different second detection components 4 are different. Specifically, those skilled in the art can select second detection ends 41 of different shapes as needed to adapt to different types of can-shaped parts. For example, plate-shaped, wedge-shaped, or flat plates with grooves or protrusions can be used to perform dimensional detection on different types of can-shaped parts, so as to accurately measure the grooves, protrusions, and transition structures of the can-shaped parts. Those skilled in the art can choose according to the actual situation without making specific limitations. Preferably, multiple second detection components 4 can operate simultaneously to detect different positions of the can-shaped parts at the same time, thereby saving detection time and improving detection efficiency.

[0028] The sensing component 5 needs to promptly detect and provide feedback on the displacement of the first detection component 3 and the second detection component 4. Therefore, in this embodiment, the sensing component 5 includes a sensing bracket 51 and a telescopic sensor 52. The sensing bracket 51 has a clamping through hole 53 corresponding to the telescopic sensor 52, and the telescopic sensor 52 is disposed in the clamping through hole 53. The detection end of the telescopic sensor 52 abuts against the first connecting slide 34 or the second connecting slide 44. This configuration limits the telescopic sensor 52 by the sensing bracket 51, ensuring that the telescopic sensor 52 remains in contact with the first connecting slide 34 or the second connecting slide 44 at all times, while preventing the telescopic sensor 52 from falling off or shifting, thereby ensuring the accuracy of the detection. Furthermore, by using the telescopic sensor 52, the displacement of the first connecting slide 34 or the second connecting slide 44 can be converted into the extension and retraction of the telescopic sensor 52. After installation, the sensing component 5 as a whole does not move; only the detection end part extends and retracts, improving integration while avoiding interference with the operation of other components.

[0029] Preferably, each of the first connecting slide 34 or the second connecting slide 44 abuts against two telescopic sensors 52, which are respectively disposed at the top or bottom of the first connecting slide 34 or the second connecting slide 44. The telescopic sensor 52 located at the top of the first connecting slide 34 or the second connecting slide 44 is used to detect vertical displacement, and the telescopic sensor 52 located at the bottom of the first connecting slide 34 or the second connecting slide 44 is used to detect horizontal displacement. Those skilled in the art can adjust the abutment position of the telescopic sensors 52 as needed, without specific limitation.

[0030] Because different detection heads have different specifications and shapes, and because the overall space at the detection position is limited, it is necessary to ensure that all detection heads can contact the can-shaped part. In this case, directly contacting the telescopic sensor 52 with the detection assembly may hinder the operation of other components. Therefore, the sensing assembly 5 also includes a displacement conductor 54, which is disposed between the first lifting plate 36 or the second lifting plate 46 and the telescopic sensor 52, and / or, between the first connecting slide 34 or the second connecting slide 44 and the telescopic sensor 52. Specifically, the displacement conductor 54 can be a combination of an extension plate 541 or an extension bracket 542 and an extension connecting rod 543. Those skilled in the art can select a suitable displacement conductor 54 according to the actual situation to proportionally transmit the displacement of the first lifting plate 36 or the second lifting plate 46 and the first connecting slide 34 or the second connecting slide 44 to the telescopic sensor 52, without specific limitations.

[0031] When the first detection component 3 or the second detection component 4 can simultaneously perform horizontal or vertical displacement, if the telescopic sensor 52, which detects the corresponding displacement distance, is set along its original direction, the installation space required for the sensing component 5 will increase significantly, affecting the integration of the detection module. Therefore, the sensing component 5 also includes a direction conversion component 55. The direction conversion component 55 is generally L-shaped, with its middle section hinged to the end of the first support 32 or the second support 42 away from the can-shaped component. The two ends of the direction conversion component 55 abut against the telescopic sensor 52 and the displacement transmission component 54, respectively. The telescopic sensor 52, the direction conversion component 55, and the displacement transmission component are all in the same plane, and the displacement transmission component 54 is perpendicular to the telescopic sensor 52. With this configuration, the horizontal displacement of the first detection component 3 or the second detection component 4 is proportionally converted into vertical displacement through the displacement transmission component 54, so that the telescopic sensors 52 are all set along the vertical direction. This reduces the overall installation space required, effectively reduces the number of component types in the sensing component 5, increases the versatility of components, and effectively reduces costs.

[0032] In this embodiment, the first detection end 31 includes a detection ball head 311, a connecting rod 312 and a connecting arm 313. The connecting arm 313 is L-shaped. One end of the connecting arm 313 is connected to the first lifting plate 36, and the other end of the connecting arm 313 is connected to the detection ball head 311 through the connecting rod 312.

[0033] Preferably, the connecting rod 312 is a telescopic pole. By adjusting the length of the connecting rod 312, the detection distance of the first detection end 31 can be adjusted, further increasing the overall detection range and effectively improving the adaptability of the detection mechanism.

[0034] To ensure that the detection ball head 311 remains in contact with the can-shaped part during the detection process, and to avoid excessive pressure on the can-shaped part caused by the detection ball head 311, resulting in damage to both, a pressure sensor is provided on the connecting rod 312 in this embodiment.

[0035] Preferably, a pressure sensor is provided on the second detection end 41.

[0036] Although this document uses terms such as fixed bracket and fixed base frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
