Description

Technical Field

[0001] This invention relates to the field of switch component testing technology, and in particular to a switch component testing fixture and testing method. Background Technology

[0002] In the manufacturing process of switchgear, the dimensional accuracy and inter-component fit of core components such as the upper and lower switch housings directly determine the assembly quality and reliability of the entire switchgear. Currently, the industry commonly uses conventional measuring tools, such as vernier calipers and go / no-go gauges, to inspect these components. However, core switchgear components are often large and complex in structure, requiring the inspection of numerous critical dimensions and multiple three-dimensional spatial fit relationships. Conventional measuring tools can only measure individual dimensions in isolation, failing to comprehensively capture the overall form and position tolerances of components and the fit tolerances between components. This results in insufficient inspection accuracy and easily leads to the problem of "individual dimensions being qualified but mismatched during assembly."

[0003] To improve inspection accuracy, some companies use high-end inspection equipment such as three-station measuring instruments. While these devices can perform multi-dimensional dimensional measurements, they have significant drawbacks: First, they are expensive, significantly increasing production and inspection costs. Second, the operation process is complex, requiring highly skilled inspectors with strong drawing recognition and operational proficiency, and the measurement process is time-consuming, making it difficult to meet the efficient inspection needs of mass production scenarios. Furthermore, neither conventional measuring tools nor high-end inspection equipment can achieve a "simulated actual assembly environment" inspection mode; the inspection benchmark deviates from the actual assembly benchmark, further affecting the reliability of the inspection results and ultimately leading to high product rework rates and production delays.

[0004] The aforementioned shortcomings of existing technologies have made accurate, efficient, and low-cost testing of large-volume, complex-structure switch components a pressing technical challenge in the industry, necessitating a testing solution that balances testing accuracy, ease of operation, testing efficiency, and cost control. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to solve the technical problems of insufficient detection accuracy, complex operation, low efficiency, high cost, and inability to effectively verify the matching between components for large-volume, complex-structured switch components with multi-dimensional matching relationships.

[0009] Preferably, the support includes an upright frame, a base frame, a fixing plate, and diagonal braces;

[0010] The base frame is located at the bottom, the upright frame is installed on the base frame, and the diagonal brace is installed between the upright frame and the base frame to maintain the stability of the upright frame and the base frame; the fixing plate is installed on the upright frame on the side opposite to the diagonal brace, and the fixing plate is used to install the slide rail module.

[0013] The sliding mounting plate is mounted on the active slider and the passive slider. The power device drives the rotating shaft to rotate, and the rotation of the rotating shaft is converted into the up and down movement of the active slider. The up and down movement of the active slider drives the sliding mounting plate to move up and down along the guide rail through the passive slider.

[0014] Preferably, the substrate has mounting holes for detecting whether the mounting holes on the upper and lower housings of the switch match.

[0015] Preferably, the tooling sleeve is used to detect the position of the wire outlet hole on the switch housing; the top of the tooling sleeve has a groove for detecting the angle of the anti-foolproof protrusion on the wire outlet hole of the switch housing.

[0016] Preferably, the mechanism plate and the tooling shaft are used to detect the lower housing of the switch; the tooling shaft is used to detect whether the operating hole of the lower housing matches the operating hole of the switch unit.

[0017] Preferably, the orientation of the tooling assembly is adjusted by adjusting the orientation of the clamping plate on the sliding mounting plate.

[0018] Preferably, by adjusting the height of the slide module, the component to be tested is placed directly on the tray.

[0019] Another aspect of the present invention provides a detection method based on the aforementioned switch component detection fixture, comprising the following steps:

[0020] S1: Reference positioning, the substrate is mounted on the sliding mounting plate by clamping plate, and the direction of clamping plate is adjusted according to the type of switch component to be tested to determine the detection direction of the tooling assembly, so that the reference surface of the substrate is adapted to the reference surface of the component to be tested.

[0021] S2: Height adaptation, start the power unit of the automatic slide assembly, drive the sliding mounting plate to move up and down through the slide module, adjust the height of the tooling assembly, so that the detection part of the tooling assembly corresponds and adapts to the test part placed on the tray.

[0022] S3: Component installation and inspection. The upper or lower housing of the switch under test is attached to the base plate. The positional matching of the mounting holes of the component under test is verified through the mounting holes of the base plate. If it is the upper housing of the switch, the position of its outlet hole is detected through the tooling sleeve, and the angle of the anti-foolproof protrusion on the outlet hole is detected through the groove at the top of the tooling sleeve. If it is the lower housing of the switch, the matching of its operating hole and the operating hole of the switch unit is detected through the tooling shaft on the mechanism plate.

[0023] S4: Result determination: If the tested component can stably fit the substrate, and the mounting holes, cable outlet / operation holes, and anti-foolproof protrusion angles are all adapted to the corresponding tooling parts, the tested component is deemed qualified; if there is misalignment, dimensional deviation, or poor adaptation, it is deemed unqualified.

[0024] The invention also provides a matching detection method for the upper and lower housings of a switch, based on the aforementioned switch component detection fixture, including the following steps:

[0025] A1: Fixture debugging, install the base plate on the sliding mounting plate through the clamp, adjust the clamp according to the testing requirements to make the fixture assembly in the preset direction, start the power unit to adjust the slide rail module, so that the fixture assembly height is adapted to the placement height of the tested parts on the tray.

[0026] A2: Individual inspection of the upper housing: Attach the upper housing of the switch to the side of the base plate with the tooling sleeve, verify the positional accuracy of the mounting holes of the upper housing through the mounting holes of the base plate, check the positional tolerance of the cable outlet hole of the upper housing through the tooling sleeve, and verify the angle tolerance of the anti-foolproof protrusion through the groove. Confirm that the individual inspection of the upper housing is qualified.

[0027] A3: Individual inspection of the lower housing. Adjust the clamping plate to flip the base plate to the side with the mechanism plate, attach the switch lower housing to the base plate, verify the matching of the mounting holes of the lower housing with the base plate reference through the mounting holes, and check the size and position of the operating holes of the lower housing through the tooling shaft to confirm that the individual inspection of the lower housing is qualified.

[0028] A4: Upper and lower housing matching verification. Keeping the base plate position unchanged, simulate the actual assembly state of the switch. Install the upper and lower housings that have passed the inspection in steps S2 and S3 on the two sides of the base plate respectively. Verify the coaxiality and fitting clearance of the mounting holes through the mounting holes. Verify the three-dimensional fitting accuracy of the upper housing outlet hole and the lower housing operation hole through the spatial position correspondence of the tooling sleeve and the tooling shaft.

[0029] A5: Comprehensive judgment. If the test results of steps A2-A4 all meet the preset requirements, then the upper and lower switch housings and their matching are deemed qualified; otherwise, they are deemed unqualified.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) High detection accuracy: The substrate adopts a reference design consistent with the actual assembly, eliminating the reference conversion error; each detection part (tooling sleeve, tooling shaft, etc.) is precisely matched with the design parameters of the parts, which can realize the synchronous detection of key dimensions, geometric tolerances and fitting accuracy, and the detection results are more in line with the actual assembly requirements.

[0032] (2) Easy to operate: No complicated equipment debugging and data processing are required. Inspectors can quickly determine the results by the compatibility of parts and tooling. It has low requirements for professional skills and can be learned quickly.

[0033] (3) High inspection efficiency: It can simultaneously complete the inspection of multiple key dimensions of a single part, and can also realize the matching verification between multiple parts. Compared with the isolated measurement of conventional measuring tools and the step-by-step measurement of high-end equipment, the inspection efficiency is improved by more than 50%.

[0034] (4) Low cost: The tooling structure is simple, the manufacturing cost is far lower than that of high-end testing equipment such as three-position measuring instruments, and no professional maintenance is required, which reduces the production and testing costs;

[0035] (5) High versatility: By changing the tooling shaft, adjusting the direction of the clamping plate and the type of power unit, it can be adapted to the testing of switch parts of different models and specifications, and has a wide range of applications;

[0047] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0048] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0049] Example 1

[0050] like Figures 1-5As shown, this embodiment provides a switch component testing fixture, including an automatic slide assembly 1, a fixture assembly 2, and a sliding mounting plate 3. The components work together to achieve accurate testing and compatibility verification of the switch components.

[0051] The bracket 12 of the automatic slide assembly 1 forms a stable support structure through the integrated design of the upright 121, base frame 122, fixing plate 123, and diagonal brace 124. This not only ensures the overall stability of the tooling during the testing process but also adapts to the installation and fixing requirements of different sites. The power unit 111 of the slide module 11 can be selected as pneumatic or electric drive according to the actual working conditions. The pneumatic method is suitable for scenarios with high adjustment speed requirements and no power supply, while the electric method is suitable for scenarios with higher adjustment accuracy requirements and remote control. The adaptability design of the two drive methods expands the application range of the tooling. The threaded engagement structure between the active slider 113 and the rotating shaft 112 accurately converts the rotational motion of the power unit 111 into linear motion. At the same time, the sliding engagement between the passive slider 114 and the guide rail 115 effectively restricts the degree of freedom of movement of the sliding mounting plate 3, avoiding swaying or offset during the up and down movement, and ensuring the accuracy and stability of the height adjustment of the tooling assembly 2.

[0052] The base plate 21 of the tooling assembly 2 adopts a design datum that is completely consistent with the actual assembly datum of the switch. Its surface roughness, flatness, and other geometric tolerances are strictly processed according to the requirements of the switch assembly datum, so that the datum in the inspection process is completely consistent with the actual use datum, eliminating the inspection error caused by datum conversion at the source. The mounting holes 211 on the base plate 21 are not only used to inspect the matching of the mounting holes of the components, but their hole walls are also treated with high-precision grinding. By measuring the degree of fit with the mounting holes of the components being tested, the hole diameter tolerance and roundness of the mounting holes can be indirectly verified, realizing the dual inspection of "position + size".

[0053] The number of tooling sleeves 22 can be designed to match the number of wire outlet holes on the switch housing 4. The outer diameter of the tooling sleeve and the design size of the wire outlet hole are in clearance fit, and the clearance value is strictly controlled within the allowable error range. By checking whether the tooling sleeve 22 can be smoothly inserted into the wire outlet hole, it is possible to quickly determine whether the position and diameter of the wire outlet hole are qualified. The angle, depth and width of the groove 221 at the top of the tooling sleeve 22 are precisely matched with the design parameters of the anti-mistake protrusion. It can not only detect the angle of the anti-mistake protrusion, but also verify the height and width dimensional tolerances of the protrusion by checking the tightness of the groove 221 and the protrusion, thus realizing multi-dimensional detection of a single structure.

[0054] The connection between the mechanism plate 23 and the tooling shaft 24 adopts a detachable design. The tooling shaft 24 of the corresponding specification can be replaced according to the operating hole parameters of different models of switch lower housing 5, which improves the versatility of the tooling. The length, diameter and installation height of the tooling shaft 24 simulate the actual assembly parameters of the switch unit operating mechanism. By checking whether the tooling shaft 24 can be smoothly inserted into the operating hole of the lower housing 5 and match the mounting hole of the simulated switch unit, the dimensional accuracy and positional accuracy of the operating hole can be directly verified.

[0055] The connection between the clamping plate 25 and the sliding mounting plate 3 is marked with an angle scale, which makes it easy for inspectors to accurately adjust the direction of the tooling assembly 2. The connection between the clamping plate 25 and the base plate 21 is fastened with high-strength bolts to ensure that the base plate 21 will not be displaced during the test. By adjusting the installation direction of the clamping plate 25, the tooling assembly 2 can be installed horizontally, vertically, or at any angle, adapting to the testing needs of switch components of different models and installation positions.

[0056] Example 2

[0057] This embodiment provides a detection method for switch components based on Embodiment 1.

[0058] 1. Tooling setup

[0059] Bracket installation: Fix the base frame 122 of the automatic slide assembly 1 to a flat ground in the testing area. The upright frame 121 is vertically installed on the base frame 122. The diagonal brace 124 is installed between the upright frame 121 and the base frame 122. Tighten the bolts to ensure that the bracket 12 is stable and does not shake. Install the fixing plate 123 on one side of the upright frame 121, ensuring that the surface of the fixing plate 123 is perpendicular to the ground.

[0060] Slide module assembly: The guide rails 115 are symmetrically installed on both sides of the fixed plate 123, and the passive slider 114 is slidably installed on the guide rails 115; the power unit 111 (a pneumatic cylinder is used in this embodiment) is installed on the top of the fixed plate 123, the rotating shaft 112 is connected to the output end of the power unit 111, and the active slider 113 is threadedly installed on the rotating shaft 112; the sliding mounting plate 3 is fixedly installed on the active slider 113 and the passive slider 114, ensuring that the sliding mounting plate 3 is parallel to the fixed plate 123.

[0061] Tooling assembly and installation: Install the tooling sleeve 22 on the front side of the base plate 21. There are 6 tooling sleeves 22, corresponding to the 6 cable outlet holes of the switch housing 4. Install the mechanism plate 23 and tooling shaft 24 on the back side of the base plate 21. Install the clamping plate 25 on both sides of the base plate 21. Fix the base plate 21 to the sliding mounting plate 3 through the clamping plate 25. Adjust the direction of the clamping plate 25 so that the front side of the base plate 21 faces the detection operation side, that is, the tooling assembly 2 is in the horizontal detection direction.

[0062] 2. Working principle and testing process

[0063] Reference positioning: The front side of the substrate 21 serves as the detection reference surface, and its flatness error is controlled within 0.02mm. It is fully compatible with the mounting reference surface of the switch housing 4, ensuring that the detection reference is consistent with the assembly reference.

[0064] Height Adaptation: Place the switch housing 4 to be tested on the tray 6, which is located below the tooling assembly 2; start the pneumatic power unit 111, which drives the rotating shaft 112 to rotate. The rotation of the rotating shaft 112 is converted into the downward movement of the active slider 113 through the threaded engagement. The active slider 113 drives the sliding mounting plate 3 and the tooling assembly 2 to move downward. The passive slider 114 slides synchronously along the guide rail 115 to ensure smooth movement; when the height of the tooling sleeve 22 corresponds to the height of the cable outlet hole of the switch housing 4, turn off the power unit 111 to complete the height adaptation.

[0065] Installation and Testing: Place the mounting reference surface of the switch housing 4 against the front of the substrate 21 and observe whether the mounting holes of the housing can be precisely aligned with the mounting holes 211 of the substrate 21. If the positioning pin can be inserted smoothly, the mounting hole position is considered to be matched. Align the tooling sleeve 22 with the cable outlet hole of the housing. If the tooling sleeve 22 can be inserted smoothly into the cable outlet hole without obvious looseness, the cable outlet hole position and diameter are considered to be qualified. Observe whether the anti-foolproof protrusion on the cable outlet hole of the housing can be fully embedded in the groove 221 at the top of the tooling sleeve 22 and fit tightly without gaps. The anti-foolproof protrusion angle and size are considered to be qualified.

[0066] Result determination: If all the above test items meet the requirements, the switch box 4 is deemed qualified; if any item has a poor fit, it is deemed unqualified.

[0067] Example 3

[0068] This embodiment provides a matching detection method for the upper and lower switch housings based on Embodiment 1.

[0069] 1. Tooling setup

[0070] The tooling setup in this embodiment is basically the same as that in embodiment 2, except that: the power unit 111 is an electric motor, which is convenient for precise height adjustment; the tooling shaft 24 is selected to be compatible with the operating hole of the switch unit to be tested.

[0071] 2. Working principle and testing process

[0072] Tooling debugging: Mount the substrate 21 onto the sliding mounting plate 3 via the clamp 25, and adjust the clamp 25 so that the front of the substrate 21 faces upward and is horizontal; start the electric power unit 111, and adjust the slide module 11 through the control system so that the height of the tooling assembly 2 is adapted to the placement height of the tray 6, ensuring that when the switch upper housing 4 is placed on the tray 6, its wire outlet hole can correspond to the tooling sleeve 22.

[0073] Individual inspection of the upper housing: Following the steps in Example 2, complete the inspection of the mounting holes, cable outlet holes, and anti-foolproof protrusions of the upper housing 4 of the switch to confirm that the upper housing is qualified.

[0074] Lower housing inspection: Loosen the fastening bolts of clamp plate 25, rotate the base plate 21 180 degrees so that the back of the base plate 21 faces upward, and re-tighten clamp plate 25; place the switch lower housing 5 on tray 6, adjust slide module 11 so that the height of tooling shaft 24 corresponds to the operating hole of lower housing 5; attach the mounting reference surface of lower housing 5 to the back of base plate 21, observe whether the mounting hole of lower housing is aligned with the mounting hole 211 of base plate 21, and insert positioning pin to verify the matching of mounting holes; align tooling shaft 24 with the operating hole of lower housing 5. If tooling shaft 24 can be smoothly inserted into the operating hole and extends to the mounting hole position of analog switch unit and matches, then lower housing 5 is deemed qualified.

[0075] Upper and lower housing matching verification: Keeping the position of the base plate 21 unchanged, install the qualified upper housing on the front of the base plate 21 and the qualified lower housing on the back of the base plate 21. Verify the coaxiality of the three by passing the positioning pin through the mounting hole of the upper housing, the mounting hole 211 of the base plate and the mounting hole of the lower housing. If the positioning pin can pass smoothly without jamming, the matching of the mounting holes is qualified. Observe the spatial position relationship between the cable outlet hole of the upper housing and the operating hole of the lower housing. Verify the three-dimensional matching accuracy of the two by simulating the fit of the conductive rod of the switch unit through the cable outlet hole of the upper housing and the operating hole of the lower housing. If the conductive rod can be assembled smoothly, the matching is qualified.

[0076] Overall judgment: If all the above test items are qualified, the upper box 4, the lower box 5 and their matching are deemed to meet the design requirements; otherwise, they are deemed unqualified.

A method for detecting the matching of an upper box and a lower box of a switch, based on the switch component detection tool according to any one of claims 1-8, characterized in that, The steps include: A1: tool debugging, the substrate (21) is installed on the sliding mounting plate (3) through the clamping plate (25), the clamping plate (25) is adjusted to make the tool assembly (2) in a preset direction, the power device (111) is started to adjust the sliding track module (11), and the height of the tool assembly (2) is adapted to the placement height of the measured parts on the tray (6). A2: The upper box body is detected alone. The switch upper box body (4) is attached to one side of the base plate (21) provided with a tool sleeve (22). The position accuracy of the upper box body mounting hole is verified through the mounting hole (211) of the base plate (21). The position tolerance of the upper box body outlet hole is detected through the tool sleeve (22). The angle tolerance of the foolproof protrusion is verified through the groove (221). It is confirmed that the upper box body alone detection is qualified. A3: The lower box body is detected alone. The clamping plate (25) is adjusted to flip the base plate (21) to one side provided with the mechanism plate (23). The switch lower box body (5) is attached to the base plate (21). The matching of the lower box body mounting hole and the base plate reference is verified through the mounting hole (211). The size and position of the lower box body operation hole are detected through the tool shaft (24). It is confirmed that the lower box body alone detection is qualified. A4: The upper and lower box bodies are matched and verified. The position of the base plate (21) is kept unchanged. The actual assembly state of the switch is simulated. The upper box body and the lower box body which have passed the detection of steps S2 and S3 are respectively installed on both sides of the base plate (21). The coaxiality and the fitting gap of the mounting holes of the two are verified through the mounting hole (211). The three-dimensional fitting accuracy of the upper box body outlet hole and the lower box body operation hole is verified through the spatial position corresponding relationship of the tool sleeve (22) and the tool shaft (24). A5: Comprehensive judgment. If the detection results of steps A2-A4 all meet the preset requirements, it is judged that the switch upper box body (4), the lower box body (5) and their matching are all qualified. Otherwise, it is judged as unqualified.
