Description

Technical Field

[0001] This invention relates to the field of workpiece inspection technology, and in particular to a comprehensive inspection device and method 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 blanks for other types of workpieces. Secondly, they can be directly used 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 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 size of the hole 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 size and the calibration ring gauge hole size 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 error value of the hole diameter can be read from the dial indicator or micrometer. While traditional testing methods can meet measurement needs to a certain extent, they suffer from problems such as 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. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a comprehensive inspection device for the dimensions of can-shaped parts, which solves the problems of low efficiency, susceptibility to human factors, and 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 the present invention is: a comprehensive inspection device for the dimensions of can-shaped parts, used to inspect the internal and external dimensions of can-shaped parts, comprising:

[0007] The frame has a worktable, a fixed support on the worktable, and a detection opening on the side wall of the fixed support;

[0008] The rotating fixed base includes a fixed component and a rotating component. The fixed component is located on the top of the fixed bracket, and the rotating component is driven to be connected to the fixed component. The rotating component drives the fixed component to rotate around the axis of the fixed component. The can-shaped part is detachably connected to the fixed component and rotates together with the fixed component. In the vertical projection, the center of the can-shaped part coincides with the rotation center of the fixed component.

[0009] The detection mechanism includes a first detection component, a second detection component, and a sensing component. The first detection component is disposed on the side of a fixed support and has a first detection end. The first detection end extends into the fixed support through a detection opening and extends upward from the rotation center of a rotating fixed base into the interior of a 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 support and surrounds the rotating 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, which are used to sense the horizontal and / or vertical movement distance of the first or second detection end.

[0010] The control module is mounted on the workbench and is electrically connected to the rotating fixed base and the detection mechanism.

[0011] 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;

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] In one embodiment, the fixing component includes a fixing base, a rotating shaft cylinder, and a connecting fixture. The fixing base is disposed on the top of the fixing bracket, the rotating shaft cylinder is embedded in the fixing base and rotatably connected to the fixing base, and the connecting fixture is rotatably disposed on the top of the fixing base and detachably connected to the rotating shaft cylinder. A connecting protrusion is provided on the side of the connecting fixture away from the rotating shaft cylinder, and a can-shaped component is disposed on the connecting fixture with the inner wall of the can-shaped component abutting against the connecting protrusion.

[0019] The rotating assembly includes a rotating connecting seat, a telescopic cylinder, a telescopic frame, a rotating motor, and a rotating disk. The rotating connecting seat is mounted on a fixed support, the telescopic cylinder is mounted on the rotating connecting seat, the telescopic frame is mounted on the output end of the telescopic cylinder, the rotating motor is mounted on the telescopic frame, and the rotating disk is mounted on the output end of the rotating motor. The bottom of the rotating disk and the rotating shaft are at the same height. In use, the telescopic frame slides linearly along the rotating connecting seat under the action of the telescopic cylinder, causing the rotating disk to abut against the bottom of the rotating shaft. The rotating motor drives the rotating disk to rotate, and the rotating disk drives the rotating shaft to rotate through friction.

[0020] In one embodiment, at least two connecting protrusions are provided. The connecting protrusions are connected to the connecting fixture via a telescopic motor. The telescopic motor is electrically connected to the control module. The control module controls the telescopic motor to extend and retract synchronously so that the extension and retraction distances of all connecting protrusions are the same.

[0021] The present invention also provides a detection method using any of the above-described comprehensive detection equipment for can-shaped parts dimensions, the steps of which are as follows:

[0022] S1. Place the can-shaped part on the fixed component so that the center of the can-shaped part coincides with the rotation center of the fixed component;

[0023] S2. The control module controls the first detection component and the second detection component to enter the initial position, and at the same time calibrates each sensing component on the first detection component and the second detection component.

[0024] S3. The control module controls the first detection component and / or the second detection component to perform horizontal displacement until they come into contact with the can-shaped part. After the first detection component and / or the second detection component come into contact with the can-shaped part, the rotating component drives the fixed component to rotate.

[0025] S4. The control module controls the first detection component and / or the second detection component to perform vertical displacement. During the movement, the first detection component and / or the second detection component maintain contact with the tank-shaped part. The sensing component transmits the extension and retraction data of the first detection component and the second detection component during the displacement process to the control module. The control module calculates the data and outputs it.

[0026] The beneficial effects of this invention are as follows:

[0027] 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.

[0028] 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, a sensing component detects the magnitude of the horizontal and / or vertical displacement of the first detection 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. By moving the second detection end on the second detection component horizontally and / or vertically, a corresponding sensing component obtains 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.

[0029] 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.

[0030] Meanwhile, since the can-shaped component has a cylindrical structure, if the detection module is only moved vertically or horizontally, it can only detect the dimension along a single vertical line. It cannot detect overall circumferential dimensional changes and cannot adapt to can-shaped components with varying circumferential positions. Therefore, this invention employs a rotating fixed base, which fixes the can-shaped component using a fixed component that can be driven by the rotating component. The rotation axis of the fixed component coincides with the center of the can-shaped component, allowing the can-shaped component to rotate without affecting the accuracy of dimensional detection, thereby effectively improving the practicality and adaptability of the equipment.

[0031] The detection method provided by this invention relies on a comprehensive detection device for can-shaped parts. Through the operation control module, it can quickly and accurately obtain the inner and outer diameter data of can-shaped parts at different positions and heights. At the same time, the obtained data is quickly calculated and output through the control module. The operation is simple, and the detection efficiency and accuracy are high.

[0032] Other features and beneficial effects of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects of the invention and other beneficial effects may be realized and obtained by means of the structures and / or components pointed out in the description and claims.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be noted that all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains, and should not be construed as limiting the invention; it should be further understood that the terms used in this invention should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this invention.

[0049] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0050] Please refer to Figures 1 to 12 A comprehensive inspection device for the dimensions of can-shaped parts, used to inspect the internal and external dimensions of can-shaped parts, comprising:

[0051] The frame 1 has a worktable 11, a fixed bracket 12 is provided on the worktable 11, and a detection opening 121 is provided on the side wall of the fixed bracket 12;

[0052] The rotating fixed base 2 includes a fixed component 21 and a rotating component 22. The fixed component 21 is disposed on the top of the fixed bracket 12. The rotating component 22 is driven to be connected to the fixed component 21, and the rotating component 22 drives the fixed component 21 to rotate around the axis of the fixed component 21. The can-shaped part is detachably connected to the fixed component 21 and rotates together with the fixed component 21. In the vertical projection, the center of the can-shaped part coincides with the rotation center of the fixed component 21.

[0053] The detection mechanism 3 includes a first detection component 31, a second detection component 32, and a sensing component 33. The first detection component 31 is disposed on the side of the fixed bracket 12 and has a first detection end 311. The first detection end 311 extends into the fixed bracket 12 through the detection opening 121 and extends upward from the rotation center of the rotating fixed base 2 into the interior of the can-shaped part. The first detection component 31 drives the first detection end 311 to move horizontally and / or vertically until it abuts against the inner wall of the can-shaped part. The second detection component 32 is disposed on the fixed bracket 12 and surrounds the rotating fixed base 2. The second detection component 32 has a second detection end 321 on the side of the second detection component near the outer wall of the can-shaped part. The second detection component 32 drives the second detection end 321 to move horizontally and / or vertically until it abuts against the outer wall of the can-shaped part. Both the first detection component 31 and the second detection component 32 are provided with sensing components 33, which are used to sense the horizontal and / or vertical movement distance of the first detection end 311 or the second detection end 321.

[0054] The control module 4 is set on the workbench 11 and is electrically connected to the rotating fixed base 2 and the detection mechanism 3.

[0055] To ensure that the displacement of the first detection end 311 and the second detection end 321 does not deviate during the detection process, thereby guaranteeing the accuracy of the detection, in this embodiment, the first detection component 31 further includes a first support 312, a first horizontal cylinder 313, a first connecting slide 314, a first lifting cylinder 315, and a first lifting plate 316; the first support 312 is fixedly connected to the fixed bracket 12, the fixed end of the first horizontal cylinder 313 is disposed on the first support 312, and the output end of the first horizontal cylinder 313... A first connecting slide 314 is provided. A first horizontal cylinder 313 pushes the first connecting slide 314 to slide horizontally along the first support 312. A first lifting cylinder 315 is provided on the top of the first connecting slide 314. A first lifting plate 316 is slidably connected to the side of the first connecting slide 314 near the can-shaped part and is driven by the first lifting cylinder 315. The first lifting cylinder 315 drives the first lifting plate 316 to move vertically along the first connecting slide 314. A first detection end 311 is connected to the first lifting plate 316.

[0056] The second detection assembly 32 also includes a second support 322, a second horizontal cylinder 323, and a second connecting slide 324. The second support 322 is mounted on the top of the fixed bracket 12. The fixed end of the second horizontal cylinder 323 is mounted on the second support 322, and the output end of the second horizontal cylinder 323 is provided with the second connecting slide 324. The second horizontal cylinder 323 pushes the second connecting slide 324 to slide horizontally along the second support 322. The second detection end 321 is located on the side of the second connecting slide 324 near the can-shaped component. This configuration, through the first connecting slide 314 and the first lifting plate 316 forming horizontal and vertical limits, ensures that the displacement of the first detection end 311 is entirely within a vertical plane, thereby guaranteeing the accuracy of the detection. The second connecting slide 324 allows the second detection end 321 to slide back and forth along a straight line, ensuring the stability of the overall structure and the accuracy of the detection.

[0057] In this embodiment, the second detection component 32 further includes a second lifting cylinder 325 and a second lifting plate 326. The second lifting cylinder 325 is disposed on the top of the second connecting slide 324. The second lifting plate 326 is slidably connected to the side of the second connecting slide 324 near the can-shaped component and is drivenly connected to the second lifting cylinder 325. The second lifting cylinder 325 drives the second lifting plate 326 to move vertically along the second connecting slide 324. The second detection end 321 is connected to the second lifting plate 326. After setting the second lifting cylinder 325 and the second lifting plate 326, the second detection end 321 can move vertically. Those skilled in the art can adjust it according to actual needs, without specific limitations.

[0058] Preferably, multiple second detection components 32 are provided, and the second detection ends 321 of different second detection components 32 are different. Specifically, those skilled in the art can select second detection ends 321 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 select according to the actual situation without making specific limitations. More preferably, multiple second detection components 32 can operate simultaneously to detect different positions of the can-shaped parts at the same time, thereby saving detection time and effectively improving detection efficiency.

[0059] The sensing component 33 needs to promptly detect and provide feedback on the displacement of the first detection component 31 and the second detection component 32. Therefore, in this embodiment, the sensing component 33 includes a sensing bracket 331 and a telescopic sensor 332. The sensing bracket 331 has a clamping through hole 333 corresponding to the telescopic sensor 332. The telescopic sensor 332 is disposed within the clamping through hole 333, and the detection end of the telescopic sensor 332 abuts against the first connecting slide 314 or the second connecting slide 324. This configuration limits the telescopic sensor 332 by the sensing bracket 331, ensuring that the telescopic sensor 332 remains in contact with the first connecting slide 314 or the second connecting slide 324 at all times, while preventing the telescopic sensor 332 from falling off or shifting, thereby ensuring the accuracy of the detection. Furthermore, by using the telescopic sensor 332, the displacement of the first connecting slide 314 or the second connecting slide 324 can be converted into the extension and retraction of the telescopic sensor 332. After installation, the sensing component 33 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.

[0060] In this embodiment, each first connecting slide 314 or second connecting slide 324 abuts against two telescopic sensors 332. The telescopic sensors 332 are respectively disposed at the top or bottom of the first connecting slide 314 or second connecting slide 324. The telescopic sensor 332 located at the top of the first connecting slide 314 or second connecting slide 324 is used to detect vertical displacement, and the telescopic sensor 332 located at the bottom of the first connecting slide 314 or second connecting slide 324 is used to detect horizontal displacement. Those skilled in the art can adjust the abutment position of the telescopic sensors 332 as needed, without specific limitation.

[0061] Because different detection heads have different specifications and shapes, and because the overall space at the detection position is limited, it is necessary to prioritize ensuring that all detection heads can contact the can-shaped part. In this case, directly contacting the telescopic sensor 332 with the detection assembly might hinder the operation of other components. Therefore, the sensing assembly 33 also includes a displacement conductor 334, which is disposed between the first lifting plate 316 or the second lifting plate 326 and the telescopic sensor 332, and / or, between the first connecting slide 314 or the second connecting slide 324 and the telescopic sensor 332. Specifically, the displacement conductor 334 can be a combination of an extension plate 3341 or an extension bracket 3342 and an extension connecting rod 3343. Those skilled in the art can select a suitable displacement conductor 334 according to the actual situation to proportionally transmit the displacement of the first lifting plate 316 or the second lifting plate 326 and the first connecting slide 314 or the second connecting slide 324 to the telescopic sensor 332; no specific limitation is made.

[0062] When the first detection component 31 or the second detection component 32 can simultaneously perform horizontal or vertical displacement, if the telescopic sensor 332, which detects the corresponding displacement distance, is set along its original direction, the installation space required for the sensing component 33 will increase significantly, affecting the integration of the detection module. Therefore, the sensing component 33 also includes a direction conversion component 335. The direction conversion component 335 is generally L-shaped, and its middle part is hinged to the end of the first support 312 or the second support 322 away from the can-shaped component. The two ends of the direction conversion component 335 abut against the telescopic sensor 332 and the displacement transmission component 334, respectively. The telescopic sensor 332, the direction conversion component 335, and the displacement transmission component are in the same plane, and the displacement transmission component 334 is perpendicular to the telescopic sensor 332. This configuration converts the horizontal displacement of the first detection component 31 or the second detection component 32 into a vertical displacement proportionally through the displacement transmission component 334, so that the telescopic sensors 332 are all set in the vertical direction. This reduces the overall installation space required, effectively reduces the number of component types of the sensing component 33, increases the versatility of the components, and effectively reduces costs.

[0063] In this embodiment, the first detection end 311 includes a detection ball head 3111, a connecting rod 3112 and a connecting arm 3113. The connecting arm 3113 is L-shaped. One end of the connecting arm 3113 is connected to the first lifting plate 316, and the other end of the connecting arm 3113 is connected to the detection ball head 3111 through the connecting rod 3112.

[0064] Preferably, the connecting rod 3112 is a telescopic pole. By adjusting the length of the connecting rod 3112, the detection distance of the first detection end 311 can be adjusted, further increasing the overall detection range and effectively improving the adaptability of the detection mechanism 3.

[0065] To ensure that the detection ball head 3111 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 3111, which could damage both, a pressure sensor is provided on the connecting rod 3112 in this embodiment.

[0066] Preferably, a pressure sensor is provided on the second detection end 321.

[0067] To ensure the stability of the can-shaped component installation and the controllability of rotation, in this embodiment, the fixing component 21 includes a fixing base 211, a rotating shaft cylinder 212, and a connecting fixture 213. The fixing base 211 is disposed on the top of the fixing bracket 12, the rotating shaft cylinder 212 is embedded in the fixing base 211 and rotatably connected to the fixing base 211, and the connecting fixture 213 is rotatably disposed on the top of the fixing base 211 and detachably connected to the rotating shaft cylinder 212. A connecting protrusion 2131 is provided on the side of the connecting fixture 213 away from the rotating shaft cylinder 212. The can-shaped component is disposed on the connecting fixture 213 and the inner wall of the can-shaped component abuts against the connecting protrusion 2131.

[0068] The rotating assembly 22 includes a rotating connecting seat 221, a telescopic cylinder 222, a telescopic frame 223, a rotating motor 224, and a rotating disk 225. The rotating connecting seat 221 is mounted on the fixed bracket 12, the telescopic cylinder 222 is mounted on the rotating connecting seat 221, the telescopic frame 223 is mounted on the output end of the telescopic cylinder 222, the rotating motor 224 is mounted on the telescopic frame 223, and the rotating disk 225 is mounted on the output end of the rotating motor 224. The rotating disk 225 is at the same height as the bottom of the rotating shaft cylinder 212. In use, the telescopic frame 223 slides linearly along the rotating connecting seat 221 under the action of the telescopic cylinder 222, causing the rotating disk 225 to abut against the bottom of the rotating shaft cylinder 212. The rotating motor 224 drives the rotating disk 225 to rotate, and the rotating disk 225 drives the rotating shaft cylinder 212 to rotate through friction.

[0069] Because the can-shaped component needs to fit tightly with the connecting fixture 213, scratches may occur to the inner wall of the can-shaped component during installation or removal. Furthermore, can-shaped components may exist in different specifications; switching to a different specification requires changing the connecting fixture 213, which is cumbersome and can reduce testing efficiency. Therefore, at least two connecting protrusions 2131 are provided. The connecting protrusions 2131 are connected to the connecting fixture 213 via a telescopic motor 2132, which is electrically connected to the control module 4. The control module 4 controls the telescopic motor 2132 to extend and retract synchronously, ensuring that all connecting protrusions 2131 extend and retract at the same distance. This design, with the telescopically controllable connecting protrusions 2131 abutting and fixing the can-shaped component, facilitates installation and disassembly while effectively improving the adaptability of the connecting fixture 213 to different specifications of can-shaped components, thereby improving testing efficiency. Moreover, because the connecting protrusions 2131 extend and retract synchronously, it ensures that the center of the can-shaped component coincides with the rotation center of the fixing component 21 after fixing. This ensures that the testing can proceed normally and that the testing is accurate.

[0070] The present invention also provides a detection method using any of the above-described comprehensive detection equipment for can-shaped parts dimensions, the steps of which are as follows:

[0071] S1. Place the can-shaped part on the fixed component 21 so that the center of the can-shaped part coincides with the rotation center of the fixed component 21;

[0072] S2, the control module 4 controls the first detection component 31 and the second detection component 32 to enter the initial position, and at the same time calibrates each sensing component 33 on the first detection component 31 and the second detection component 32.

[0073] S3, the control module 4 controls the first detection component 31 and / or the second detection component 32 to perform horizontal displacement until they come into contact with the can-shaped part. After the first detection component 31 and / or the second detection component 32 come into contact with the can-shaped part, the rotating component 22 drives the fixing component 21 to rotate.

[0074] The control module 4 controls the first detection component 31 and / or the second detection component 32 to perform vertical displacement. During the movement, the first detection component 31 and / or the second detection component 32 maintain contact with the can-shaped part. The sensing component 33 transmits the extension and retraction data of the first detection component 31 and the second detection component 32 during the displacement process to the control module 4. The control module 4 calculates the data and outputs it.

[0075] Preferably, in S1, when the can-shaped part is placed on the fixing component 21, the control module 4 controls the telescopic motor 2132 to drive the connecting protrusion 2131 to extend and retract synchronously until the can-shaped part is fixed.

[0076] Preferably, in the overall detection process of S3, taking the first detection component 31 as an example, when the first lifting cylinder 315 is not in operation, the sensing component 33 only detects the diameter of the lower cross-section inside the can-shaped part; when the first lifting cylinder 315 moves, the sensing component 33 detects the overall movement inside the can-shaped part and judges the degree of diameter change; when the first lifting cylinder 315 moves to its position, it detects the diameter of the upper cross-section inside the can-shaped part. The detection process of the second detection component 32 is similar. Those skilled in the art can adjust it according to the specific shape of the second detection end 321 and the type of can-shaped part, without limitation.

[0077] Preferably, during the overall detection process of S3, the control module 4 adjusts the extension and retraction of the first horizontal cylinder 313 and the second horizontal cylinder 323 according to the pressure signals transmitted from the pressure sensors on the first detection end 311 and the second detection end 321, so that the first detection end 311 and the second detection end 321 maintain contact with the can-shaped part within a set range.

[0078] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of the present invention can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or the background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0079] Although this document frequently uses terms such as fixed bracket and rotating fixed base, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention. The terms "first," "second," etc. (if present) in the specification and claims of the embodiments of the invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
