Technical Field
[0001] This invention relates to the field of lamp post verticality testing technology, and more specifically, to a verticality testing system and method for welded lamp posts. Background Technology
[0002] Welded light poles are an important component of lighting fixtures. They are formed by welding a supporting pole and a flat connecting flange. Their overall verticality directly affects the post-installation stability, aesthetic consistency, and subsequent assembly precision.
[0003] Existing patent CN213067415U discloses a device for detecting the perpendicularity of metal workpieces. It uses a clamping mechanism to fix the workpiece to a base, and then a moving mechanism drives a probe to scan the surface of the workpiece. The contact state between the probe and the workpiece determines whether the perpendicularity of the workpiece surface meets the requirements. However, in the actual inspection of welded light poles, because welded light poles are usually long, hollow at both ends, and have an irregular structure formed by welding the support pole to the flange, the probe scanning of the outer surface is affected by the morphology of the weld and flange, making it difficult to accurately reflect the true perpendicular relationship between the welded flange and the light pole axis.
[0004] Therefore, it is necessary to design a verticality detection system and method for welding light poles to solve the problems existing in the current technology. Summary of the Invention
[0005] In view of this, the present invention proposes a verticality detection system and method for welded light poles, aiming to solve the problem that the detection process of the outer surface of welded light poles is affected by the morphology of the weld and flange, making it difficult to accurately reflect the true vertical relationship between the welded flange and the axis of the light pole.
[0006] In one aspect, the present invention proposes a verticality detection system for welded light poles, comprising: a base, a support mechanism, and a detection mechanism; The support mechanism includes a lamp post support block, a geared motor, a cylinder, a conical positioning column, and a conical telescopic positioning column; the lamp post support block is used to place the welding lamp post to be inspected; the geared motor and the cylinder are used to drive the conical positioning column and the conical telescopic positioning column to clamp the welding lamp post to be inspected placed on the lamp post support block; the geared motor is also used to drive the clamped welding lamp post to be inspected to rotate. The detection mechanism includes a metal induction switch, a data processing module, and an alarm module. The metal induction switch is used to collect the sensing distance data of the welding light pole to be tested during rotation. The data processing module is used to determine the end face runout of the welding light pole to be tested based on the sensing distance data; compare the end face runout with a runout threshold; and determine whether the verticality of the welding light pole to be tested is qualified based on the comparison result. The alarm module is used to generate an alarm signal when the verticality of the welding light pole to be tested is determined to be unqualified.
[0007] Furthermore, the geared motor and the cylinder are fixed at both ends on the base; the lamp post support block is fixed on the base and located between the geared motor and the cylinder.
[0008] Furthermore, the conical positioning post is located at the output end of the geared motor; the conical telescopic positioning post is located at the output end of the cylinder.
[0009] Furthermore, the lamp post support block includes a first lamp post support block and a second lamp post support block; the second lamp post support block is equipped with the inductive switch.
[0010] Furthermore, the cylinder drives the conical telescopic positioning column to translate axially, causing the conical positioning column and the conical telescopic positioning column to be inserted into the inner holes at both ends of the welding lamp post to be tested for centering and clamping; the reduction motor drives the conical positioning column to rotate, causing the welding lamp post to be tested and the conical telescopic positioning column to rotate synchronously.
[0011] Furthermore, when the metal induction switch collects the sensing distance data of the welding lamp post to be detected during the rotation process, it includes: The metal induction switch collects the sensing distance data of the welding lamp pole to be tested rotating one revolution based on a preset sampling frequency.
[0012] Furthermore, when the data processing module determines the end face runout of the welding light pole to be detected based on the sensing distance data, it includes: Acquire the sensing distance data of the welding light pole to be tested rotating one revolution to construct an original data sequence; perform data cleaning on the original data sequence, identify and remove outliers in the original data sequence whose adjacent value changes by more than abrupt change threshold, and obtain an effective data sequence; traverse all distance values in the effective data sequence, and filter peak distances and valley distances; calculate the difference between the peak distance and the valley distance, and use the difference as the end face runout of the welding light pole to be tested.
[0013] Furthermore, when the data processing module determines whether the verticality of the welded light pole to be inspected is qualified based on the comparison result, it includes: When the end face runout is less than or equal to the runout threshold, the verticality of the welded light pole to be tested is deemed qualified. When the end face runout exceeds the runout threshold, the verticality of the welded light pole to be tested is deemed unqualified.
[0014] Furthermore, the welding pole to be inspected includes a supporting pole and a flat connecting flange; the supporting pole and the flat connecting flange are welded perpendicularly.
[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting up a support mechanism and a detection mechanism to cooperate with each other, the lamp post support block stably supports the welded lamp post to be inspected, and the automatic positioning and clamping of both ends of the lamp post is achieved through a geared motor, cylinder, conical positioning column, and conical telescopic positioning column. This ensures that lamp posts of different specifications can be kept coaxially fixed with the rotation axis, avoiding measurement errors caused by clamping offset during the inspection process, and improving the consistency and repeatability of the inspection. The geared motor drives the welded lamp post to be inspected to rotate at a uniform speed after clamping. During the rotation, the metal induction switch continuously collects the sensing distance data of the lamp post end. The data processing module automatically calculates the end face runout based on the sensing distance data and compares the end face runout with a preset runout threshold to automatically determine whether the verticality of the welded lamp post meets the requirements. The inspection efficiency is high, the inspection results are objective and reliable, and the impact of human factors on the inspection accuracy is reduced. When the inspection result determines that the verticality of the welded lamp post is unqualified, the alarm module can output an alarm signal in a timely manner to remind the operator to rework or reject the lamp post, realizing online rapid judgment of the quality of the welded lamp post.
[0016] On the other hand, this application also provides a method for detecting the verticality of welded light poles, applied to the aforementioned verticality detection system for welded light poles, comprising: The driving conical positioning column and the conical telescopic positioning column clamp the welding light pole to be tested placed on the light pole support block, and drive the clamped welding light pole to be tested to rotate; Collect sensing distance data of the welding light pole to be tested during the rotation process; determine the end face runout of the welding light pole to be tested based on the sensing distance data; compare the end face runout with the runout threshold; and determine whether the verticality of the welding light pole to be tested is qualified based on the comparison result. An alarm signal is generated when the verticality of the welded light pole to be tested is determined to be unqualified.
[0017] It is understandable that the above-mentioned verticality detection system and method for welding light poles have the same beneficial effects, and will not be elaborated further here. Attached Figure Description

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] In some embodiments of this application, see Figure 1-2 As shown, a verticality detection system for welded light poles is proposed, comprising: a base 1, a support mechanism, and a detection mechanism; The support mechanism includes a lamp post support block, a geared motor 3, a cylinder 4, a conical positioning column 5, and a conical telescopic positioning column 6; the lamp post support block is used to place the lamp post to be inspected; the geared motor 3 and the cylinder 4 are used to drive the conical positioning column 5 and the conical telescopic positioning column 6 to clamp the lamp post to be inspected placed on the lamp post support block; the geared motor 3 is also used to drive the clamped lamp post to be inspected to rotate. The testing mechanism includes a metal induction switch 7, a data processing module 9, and an alarm module 8. The metal induction switch 7 is used to collect the sensing distance data of the welding light pole to be tested during rotation. The data processing module 9 is used to determine the end face runout of the welding light pole to be tested based on the sensing distance data. The end face runout is compared with the runout threshold. Based on the comparison result, it is determined whether the verticality of the welding light pole to be tested is qualified. The alarm module 8 is used to generate an alarm signal when the verticality of the welding light pole to be tested is determined to be unqualified.
[0022] Specifically, the support mechanism is used for placing, centering, clamping, and rotating the welding light pole to be inspected; the inspection mechanism is used to collect, process, and output the verticality judgment result of the end face runout of the welding light pole during rotation. Specifically, the support mechanism includes a light pole support block, a geared motor 3, a cylinder 4, a conical positioning column 5, and a conical telescopic positioning column 6. The light pole support block supports the welding light pole to be inspected, placing it at a preset inspection height and maintaining its initial placement posture. The geared motor 3 and the cylinder 4 are fixed to both ends of the base 1, and the light pole support block is fixed to the base 1 and located between the geared motor 3 and the cylinder 4, thus forming a stable clamping and inspection space on the base 1. The conical positioning column 5 is located at the output end of the geared motor 3, and the conical telescopic positioning column 6 is located at the output end of the cylinder 4; the two form an axial centering support structure in the inner holes at both ends of the welding light pole to be inspected.
[0023] Furthermore, the lamp post support includes a first lamp post support 21 and a second lamp post support 22. The first lamp post support 21 and the second lamp post support 22 are respectively disposed at support positions along the length of the lamp post to be inspected, for segmented support of the welded lamp post. A metal induction switch 7 is installed on the second lamp post support 22. The position of the metal induction switch 7 is preferably set in the detection area corresponding to the planar connecting flange 11 of the welded lamp post to be inspected, so that it can continuously monitor the radial position change of the flange end face during the rotation of the welded lamp post to be inspected.
[0024] In this embodiment, the welded light pole to be inspected includes a supporting light pole 10 and a flat connecting flange 11, which are welded perpendicularly. Since the flat connecting flange 11 is a critical connection point in the subsequent assembly of the entire lamp, if there is a welding misalignment between the flat connecting flange 11 and the supporting light pole 10, the entire light pole will easily tilt after assembly, resulting in significant misalignment of the lamp after installation and failing to meet the verticality requirements of the entire lamp. For scenarios with high lamp heights, the overall lamp misalignment is typically required to be no more than 0.7% of the lamp height. Therefore, this embodiment automatically detects the welding verticality before assembling the light pole assembly, enabling timely rejection of unqualified products and preventing unqualified light poles from entering subsequent assembly processes.
[0025] In a preferred embodiment, cylinder 4 drives the conical telescopic positioning post 6 to translate axially. After the welding lamp post to be inspected is placed on the lamp post support block, cylinder 4 is activated, causing the conical telescopic positioning post 6 to extend forward and cooperate with the conical positioning post 5 located at the output end of the geared motor 3, inserting into the inner holes at both ends of the welding lamp post to be inspected. Since both the conical positioning post 5 and the conical telescopic positioning post 6 have conical guide structures, they can automatically correct their orientation during insertion, gradually guiding the welding lamp post to a position coaxial with the rotation axis, thus achieving centering and clamping of the lamp post.
[0026] After clamping, the geared motor 3 drives the conical positioning column 5 to rotate. The conical positioning column 5 drives the welding lamp post to be inspected to rotate synchronously. While the cylinder 4 remains extended, the conical telescopic positioning column 6 rotates synchronously with the welding lamp post to be inspected, thus enabling the welding lamp post to be inspected to complete a full rotation inspection in a stable clamping state. Since the welding lamp post to be inspected is supported and positioned through the inner holes at both ends, its rotation reference is consistent with the actual axis, which can avoid the clamping eccentricity problem caused by external clamping support and improve the verticality detection accuracy.
[0027] The testing mechanism includes a metal induction switch 7, a data processing module 9, and an alarm module 8. The metal induction switch 7, data processing module 9, and alarm module 8 are electrically connected. The metal induction switch 7 is used to collect the sensing distance data of the welding light pole under test during rotation; the data processing module 9 is used to determine the end face runout of the welding light pole under test based on the sensing distance data, compare the end face runout with a runout threshold, and determine whether the verticality of the welding light pole under test is qualified based on the comparison result; the alarm module 8 is used to generate an alarm signal when the verticality of the welding light pole under test is determined to be unqualified.
[0028] Specifically, the metal sensor switch 7 is mounted on the second lamp post support block 22 and located at the flange detection position of the lamp post to be inspected. The metal sensor switch 7 employs a non-contact detection method, continuously sensing the flange face or the metal end face adjacent to the flange during the rotation of the lamp post to be inspected, outputting sensing distance data reflecting the change in distance between the lamp post and the metal sensor switch 7. Since a vertical deviation exists between the flange welding surface and the lamp post axis, the distance between the flange edge or end face and the metal sensor switch 7 will periodically fluctuate during one rotation of the lamp post. Therefore, by collecting the sensing distance data for one rotation, the end face fluctuation state can be reflected.
[0029] Furthermore, when the metal induction switch 7 collects the sensing distance data of the welding light pole under test during rotation, it includes: the metal induction switch 7 collects the sensing distance data of the welding light pole under test for one revolution based on a preset sampling frequency. The preset sampling frequency can be set according to the rotation speed of the welding light pole under test, the flange size, and the allowable runout range to ensure that a sufficient number of distance sampling points can be obtained within one revolution of the light pole. The sampling frequency is determined according to the actual working conditions. Generally, the higher the sampling frequency, the better it is to capture subtle distance changes caused by flange welding misalignment, thereby improving the accuracy of end face runout calculation.
[0030] In this embodiment, the welding light pole to be inspected is held and rotated by the geared motor 3 and the cylinder 4, while the metal induction switch 7 is always positioned corresponding to the flange detection area. As the welding light pole rotates around its own axis, the metal induction switch 7 synchronously records the change curve of its sensing distance during the entire rotation, forming a complete set of sensing distance data. This set of sensing distance data reflects the spatial position change of the flange relative to the metal induction switch 7 at different angular positions, and can be used to further analyze the perpendicularity deviation of the flange welding surface.
[0031] Furthermore, when the data processing module 9 determines the end face runout of the welding light pole to be inspected based on the sensing distance data, it includes: acquiring the sensing distance data of the welding light pole to be inspected rotating one revolution, and constructing an original data sequence; cleaning the original data sequence, identifying and removing outliers in the original data sequence whose adjacent values change by more than the mutation threshold, and obtaining an effective data sequence; traversing all distance values in the effective data sequence, and filtering the peak distance and valley distance; calculating the difference between the peak distance and the valley distance, and using the difference as the end face runout of the welding light pole to be inspected.
[0032] Specifically, the data processing module 9 first receives the raw sensing distance signal output by the metal induction switch 7 and organizes it into a raw data sequence according to the sampling time sequence. Since the raw data sequence may contain abnormal sampling points due to factors such as electromagnetic interference, mechanical vibration, local surface burrs, or transient jitter during on-site detection, data cleaning is necessary. The data processing module 9 identifies sampling points with a change in distance greater than a mutation threshold by comparing the distance changes between adjacent sampling points, and removes these as outliers to avoid errors in the calculation results of the fluctuation amount caused by abnormal data. The mutation threshold is determined based on historical statistical data.
[0033] After data cleaning, the data processing module 9 traverses and analyzes the valid data sequences, filtering out the peak and valley distances. The peak distance represents the maximum distance between the welded light pole under test and the metal induction switch 7 during one rotation; the valley distance represents its minimum distance. Since end face runout causes periodic ups and downs on the flange face during rotation, the difference between the peak and valley distances directly reflects the degree of deviation of the welded flange from the axis of the supporting light pole 10. The data processing module 9 determines the difference between the peak and valley distances as the end face runout, and uses this as the basis for determining perpendicularity.
[0034] Furthermore, based on the comparison results, the data processing module 9 determines whether the verticality of the welded light pole under inspection is qualified. This includes: if the end face runout is less than or equal to the runout threshold, the verticality of the welded light pole under inspection is deemed qualified; if the end face runout is greater than the runout threshold, the verticality of the welded light pole under inspection is deemed unqualified. The runout threshold can be preset according to product standards, process requirements, and allowable deviations in light pole height. For example, in some implementation scenarios, the corresponding allowable end face runout range can be calculated based on the control requirement that the overall lamp tilt after assembly does not exceed 0.7% of the lamp height, and this range can be used as the runout threshold.
[0035] In one specific workflow, the welded flange lamp post is first placed on two lamp post supports. These supports provide initial support to prevent the lamp post from falling or wobbling. Then, the equipment is started, and cylinder 4 drives the conical telescopic positioning pin 6 forward, causing it and the conical positioning pin 5 at the output of the geared motor 3 to insert into the inner holes at both ends of the welded lamp post to be inspected. Because both ends are conical, automatic center correction is achieved during insertion, ensuring the welded lamp post is coaxially clamped. After clamping, the welded lamp post is suspended and partially detached from the support of the lamp post supports to reduce external interference during rotation.
[0036] Subsequently, the geared motor 3 starts and drives the conical positioning column 5 to rotate, causing the welding light pole to be inspected to rotate synchronously around its own axis. Simultaneously, the metal induction switch 7 installed on the second light pole support block 22 continuously detects the flange position, collecting real-time sensing distance data during one rotation of the welding light pole. The data processing module 9 cleans, analyzes, and calculates the collected results to obtain the end face runout, which is then compared with a preset runout threshold.
[0037] When the test results show that the end face runout does not exceed the runout threshold, it indicates that the welding perpendicularity between the welded flange and the supporting light pole 10 meets the requirements, and the system outputs a qualified result. When the end face runout exceeds the runout threshold, it indicates that the welded flange has obvious skewing or welding deviation, and the system immediately outputs an alarm signal from the alarm module 8. The alarm signal can be an audible and visual alarm, flashing light, buzzer prompt, or control command output to prompt the operator to rework, re-inspect, or reject the unqualified welded light pole.
[0038] In one specific embodiment, the welding pole to be tested is a common household lighting pole with an overall height of 1m. The welding pole to be tested includes a supporting pole 10 and a flat connecting flange 11, which are vertically welded to form an integral structure.
[0039] Since this type of light pole is 1m high, if there is a significant welding misalignment between the welded flange and the supporting light pole 10, the entire light pole is prone to tilting after installation. According to the lighting installation requirements, in this embodiment, the allowable vertical deviation is converted to a maximum offset of 7mm at the top of the light pole; that is, 7mm is used as the corresponding runout threshold in this embodiment. In other words, when the detected end-face runout is greater than 7mm, the welded light pole is deemed to be unqualified for verticality; when the end-face runout is less than or equal to 7mm, its verticality is deemed acceptable.
[0040] During testing, the 1m lamp post, after welding, is first placed on the lamp post support block on the base 1. The lamp post support block provides initial support for the middle of the lamp post, keeping it horizontal. Then, cylinder 4 is activated, causing the conical telescopic positioning pin 6 at the output end of cylinder 4 to move forward axially. Simultaneously, the conical positioning pin 5 and the conical telescopic positioning pin 6 at the output end of the geared motor 3 are inserted into the inner holes at both ends of the lamp post, centering and clamping it. Because the conical structure has a guiding function, it can automatically correct minor offsets during lamp post clamping, thus keeping the lamp post axis as coaxial as possible with the rotation axis of the geared motor 3.
[0041] After clamping, the lamp post is suspended and lifted, detached from the partial support of the lamp post support block. The geared motor 3 drives the conical positioning column 5 to rotate, causing the lamp post to be inspected to rotate uniformly around its own axis for one revolution. At this time, the metal induction switch 7 installed on the second lamp post support block 22 corresponds to the outer side or end face of the welding flange and continuously collects sensing distance data at a preset sampling frequency. For example, if the sampling frequency is set to 20 times per second and the time for the lamp post to complete one revolution is 3 seconds, approximately 60 sets of sensing distance data can be obtained for subsequent analysis.
[0042] After receiving the sensing distance data output by the metal induction switch 7, the data processing module 9 first sorts and cleans the data. If the distance between a certain sampling point and its adjacent sampling points changes too much, exceeding a preset abrupt change threshold, the point is identified as an outlier and removed to avoid instantaneous interference affecting the detection results. Then, in the remaining valid data sequence, all distance values are traversed, the maximum and minimum distance values are selected, and the difference between the two is calculated. This difference is the end face runout obtained in this detection.
[0043] For example, when inspecting a 1m light pole, the maximum value in the effective sensing distance sequence is 18.6mm and the minimum value is 12.1mm, then the end face runout is 6.5mm. Since 6.5mm is less than or equal to the 7mm runout threshold set in this embodiment, the data processing module 9 determines that the verticality of the welded light pole is qualified, the alarm module 8 does not issue an alarm signal, and the system outputs a qualified result.
[0044] For example, when inspecting another 1m light pole, the maximum value in the effective sensing distance sequence was 20.4mm and the minimum value was 11.8mm, so the end face runout was 8.6mm. Since 8.6mm is greater than the 7mm runout threshold, the data processing module 9 determined that the verticality of the welded light pole was unqualified, and the alarm module 8 immediately output an alarm signal, prompting the operator to rework or remove the light pole.
[0045] Based on another preferred embodiment described above, see [link to preferred embodiment]. Figure 3 As shown, this embodiment provides a method for detecting the verticality of welded light poles, applied to the aforementioned verticality detection system for welded light poles, including: S100: Drive the tapered positioning column and tapered telescopic positioning column to clamp the welding light pole to be tested placed on the light pole support block, and drive the clamped welding light pole to be tested to rotate. S200: Collects sensing distance data of the welding light pole to be inspected during the rotation process; determines the end face runout of the welding light pole to be inspected based on the sensing distance data; compares the end face runout with the runout threshold; and judges whether the verticality of the welding light pole to be inspected is qualified based on the comparison result. S300: An alarm signal is generated when the verticality of the welded light pole to be inspected is determined to be unqualified.
[0046] In summary, by setting up a support mechanism and a testing mechanism that work together, the lamp post support block provides stable support for the welded lamp post to be tested. Automatic positioning and clamping of both ends of the lamp post are achieved through a geared motor, cylinder, conical positioning column, and conical telescopic positioning column. This ensures that lamp posts of different specifications remain coaxially fixed with the rotation axis, avoiding measurement errors caused by clamping misalignment during testing and improving the consistency and repeatability of the test. The geared motor drives the welded lamp post to be tested to rotate at a uniform speed after clamping. During rotation, the metal induction switch continuously collects the sensing distance data at the end of the lamp post. The data processing module automatically calculates the end face runout based on the sensing distance data and compares it with a preset runout threshold to automatically determine whether the verticality of the welded lamp post meets the requirements. This method has high testing efficiency, objective and reliable test results, and reduces the impact of human factors on testing accuracy. When the test results indicate that the verticality of the welded lamp post is unqualified, the alarm module can promptly output an alarm signal to remind the operator to rework or reject the post, achieving rapid online quality assessment of the welded lamp post.
[0047] 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 it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
