Description
Technical Field
[0001] This utility model relates to the field of electricity meter testing technology, and in particular to a guide rail meter testing fixture. Background Technology
[0002] Rail-mounted energy meters are gradually expanding their market application due to their small size, high accuracy, good reliability, and convenient installation. Like other types of energy meters, rail-mounted energy meters need to undergo a full-meter live-line test before final assembly, sealing, or ultrasonic welding.
[0003] In related technologies, when conducting live-line testing of rail-mounted energy meters, the process of inserting the connector lug into the meter's terminals and tightening the screws is cumbersome. Furthermore, when the host computer connects to the infrared head to set data and control the meter's internal relays, manual operation requires aligning the infrared head with the meter's infrared communication window each time, resulting in low communication testing efficiency. If the infrared head is not accurately aligned with the meter's infrared communication window, communication between the host computer and the meter may fail. Utility Model Content

[0029] The following is combined Figures 1-3This invention describes a guide rail gauge testing fixture, comprising a fixture housing 10, a displacement driving assembly 20, and a positioning detection assembly 30. The fixture housing 10 has a testing platform 11, and an installation space 13 is formed inside the fixture housing 10. A sliding through hole 111 is provided on the testing platform 11. The displacement driving assembly 20 includes a support frame 21, a linear driving device 22, and a connecting pad 23. The support frame 21 is disposed within the installation space 13, the linear driving device 22 is connected to the support frame 21, and the connecting pad 23 is connected to the linear driving device 22. The linear driving device 22 is used to drive the connecting pad 23 to reciprocate within the sliding through hole 111. The positioning detection assembly 30 includes a fixed abutment seat 31 and a movable tray 32. The fixed abutment seat 31 is disposed on the testing platform 11 and is located on the movable tray 32. On one side of the fixed abutment 31 facing the movable tray 32, there is an electric spring probe 313 and a test spring probe 314. The movable tray 32 has a fixed station for fixing the guide rail. The movable tray 32 is fixedly connected to the connecting pad 23 to drive the movable tray 32 to move toward or away from the fixed abutment 31. It is configured such that in the initial working condition, the electric spring probe 313 and the test spring probe 314 are disengaged from the guide rail. In the test working condition, the electric spring probe 313 and the test spring probe 314 abut against the guide rail. The movable tray 32 is also provided with a probe support structure 33 and an infrared probe 34. The infrared probe 34 is movably connected to the probe support structure 33. The probe support structure 33 is used to make the infrared probe 34 face the guide rail in the fixed station in the test working condition. The guide rail meter requires live testing, which necessitates connecting wires to the terminals inside the meter. In this embodiment, the displacement drive component 20 moves the movable tray 32, thereby enabling the guide rail meter to contact and disengage from the fixed abutment seat 31. This achieves automatic connection and disconnection of the terminals. Furthermore, by setting a fixed station on the movable tray 32 to fix the conductive meter, the stability and efficiency of the test are improved. Automated alignment can be achieved through the infrared probe 34, increasing the automation level of the detection, avoiding the risk of electric shock during manual operation, and improving the operational safety of the test personnel.
[0030] Specifically, the test platform 11 can be equipped with multiple test assemblies, each test assembly including the displacement drive component 20 and the positioning detection component 30 mentioned above, such as... Figure 1As shown, two sets of test assemblies are arranged side by side on the test platform 11, and the two sets of test assemblies have the same structure. The tooling box 10 is a box structure with a right-angled trapezoidal shape on the side. Its box structure is formed by a top plate, a bottom plate and a side plate fixedly enclosing it (such as by bolts to fix the top plate, bottom plate and side plate). Since the side of the box is trapezoidal, a sloping structure is formed on one side of the tooling box 10. An installation space 13 for component installation is formed inside the box. When connected, the support frame 21 is connected to the bottom plate of the installation space 13 to support the linear drive device 22, the connecting pad 23 and the positioning detection component 30, and to provide a basic support for the stable operation of the moving pallet 32.
[0031] like Figure 2 , Figure 3 As shown, the linear drive device 22 has a fixed part for connection to the outside and a drive part for movement under the action of a driving force. The fixed part is connected to the support frame 21, and the drive part is connected to the connecting pad 23, so that the connecting pad 23 can be moved when the drive part moves. For example, in a specific configuration, the linear drive device 22 includes a slide cylinder. The cylinder body of the slide cylinder is connected to the support frame 21, and the piston rod of the slide cylinder is provided with a sliding block. The sliding block is connected to the connecting pad 23, so that when the sliding block reciprocates under the drive of the piston rod, it simultaneously drives the connecting pad 23 and the moving tray 32 to move.
[0032] Of course, the above should be understood as an example of the linear drive device 22, not a limitation thereof. The linear drive device 22 can be other devices, such as electric actuators, linear motors, ball screw drive systems, etc. In this specification, a slide cylinder is used as an example.
[0033] The probe support structure 33 and the infrared probe 34 are movably connected, allowing the infrared probe 34 to be selectively positioned on the ground guide rail. Any method that enables the movable connection between the infrared probe 34 and the probe support structure 33 is acceptable. For example, it can be achieved through a universal joint, telescopic movement, or a rotating shaft. This movable connection allows the infrared probe 34 to have an initial position and a test position. In the initial position, the infrared probe 34 can face away from the guide rail, facilitating installation of the guide rail in a fixed location. In the test position, the infrared probe 34 can be adjusted to face the guide rail. The infrared probe 34 can be driven manually or by a drive device. For example, in the initial state, the detection end of the infrared probe 34 faces away from or away from the guide rail. In the test state, the infrared probe 34 can be manually rotated or folded to turn or bring its detection end closer to the guide rail, thus achieving detection.
[0034] Understandably, compared to traditional manual connection of terminals, the solution in this embodiment, by setting a spring probe on one side of the fixed abutment 31 and a movable tray 32 on one side of the fixed abutment 31, allows the terminals inside the guide rail meter to abut against the spring probe under the drive of the displacement drive component 20. This enables live testing of the guide rail meter, avoiding the cumbersome steps of manual connection, reducing the risk of electric shock during manual connection, and improving the operational safety of testers. Furthermore, by setting an infrared probe 34 on the movable tray 32, communication testing of the guide rail meter can be achieved, improving its testing efficiency and accuracy.
[0035] In specific settings, the stroke of the linear drive device 22 and the sliding through hole 111 is such that after the moving tray 32 moves to the predetermined position, the wiring terminal inside the guide rail table abuts against the spring probe, and the position of the infrared probe 34 is such that when the spring probe abuts against the wiring terminal inside the guide rail table, the detection end of the infrared probe 34 is exactly located at the infrared communication window position of the guide rail table.
[0036] Furthermore, such as Figure 1 , Figure 3 As shown, the fixture housing 10 is also equipped with a self-locking button 12 and an interface 14. The interface 14 is used to connect an external power consumption tester, a power supply, and a gas source. The power supply provides power to the entire fixture, and the gas source provides pressurized gas to the sliding platform. The self-locking button 12 is electrically connected to the power supply through a structure, and is used to start or stop the fixture. For example, pressing the self-locking button 12 starts the fixture test, and pressing the self-locking button 12 again after the test is completed stops the test.
[0037] In specific implementation methods, such as Figure 1 As shown, the self-locking button 12 is located on the inclined side of the tooling housing 10, which facilitates operation. The power-on spring probe 313 and the test spring probe 314 inside the fixed abutment 31 are connected to the power supply via wires.
[0038] In some embodiments, such as Figure 3 As shown, the linear drive device 22 is also equipped with a baffle 222, which is located within the installation space 13. A fixing block 40 is provided at the top of the installation space 13, located on one side of the linear drive device 22. The fixing block 40 is equipped with a self-reset button 41, and the fixing abutment 31 is electrically connected to the self-reset button 41. The self-reset button 41 is located on the surface facing the baffle 222, so that the baffle 222 and the self-reset button 41 are spaced apart in the initial working condition. In the test working condition, the baffle 222 and the self-reset button 41 abut against each other to achieve electrical conduction. The power-on spring probe 313 and the test spring probe 314 are exposed in the initial state. In this embodiment, the cooperation between the self-reset button 41 and the baffle 222 ensures that the power-on spring probe 313 and the test spring probe 314 are in a non-conductive state in the initial state, and are only electrically conductive in the test working condition, further avoiding the safety risks caused by accidental contact.
[0039] Specifically, such as Figure 2 As shown, a through hole 112 is provided on the test platform 11 at the connection position of the fixed abutment 31. The wire is electrically connected to the self-reset button 41 through the through hole 112. The self-reset button 41 is connected to an external power source through the interface 14 on the tooling housing 10, thereby enabling the self-reset button 41 to control the on / off of the power supply on the fixed abutment 31, further improving safety performance. In specific connection, the baffle 222 is connected to the slider on the linear drive device 22 and is located on the side of the slider facing the fixed block 40. The slider moves under the drive of the linear drive device 22.
[0040] The self-reset button 41 is a conventional button that is electrically conductive only when pressed and disconnected when released. This allows it to be linked with the displacement drive assembly 20. Specifically, in the initial operating condition, the baffle 222 moves away from the self-reset button 41, and the guide rail gauge also moves away from the fixed abutment seat 31. During testing, the guide rail gauge, driven by the linear drive device 22, moves towards the fixed abutment seat 31, achieving contact between its connection terminal and the spring probe. Simultaneously, the baffle 222 moves accordingly and contacts the self-reset button 41, achieving electrical conductivity. This results in the linkage control of the spring probe contacting the guide rail gauge and the baffle 222 contacting the self-reset button 41.
[0041] It is understood that in this embodiment, the power-on spring probe 313 and the test spring probe 314 are exposed structures, which pose a risk of accidental electric shock in the initial state. In this embodiment, the automatic reset button and the spring probe on the fixed abutment seat 31 are mechanically linked to reduce the risk of accidental electric shock and improve safety performance.
[0042] In some embodiments, such as Figure 4 , Figure 5 As shown, the probe support structure 33 includes a support column 331 and a movable arm 333. One end of the support column 331 is fixedly connected to the movable tray 32, and the other end of the support column 331 is provided with a rotation drive unit 332. One end of the movable arm 333 is connected to the rotation drive unit 332, and the infrared probe 34 is fixedly connected to the movable arm 333. When detecting, the infrared probe 34 is located above the guide rail gauge, which may hinder the installation of the guide rail gauge in the initial working condition. In this embodiment, the rotation drive unit 332 allows the infrared probe 34 to rotate at a certain angle to avoid obstruction, thus facilitating the installation of the guide rail gauge.
[0043] Specifically, the support column 331 is arranged vertically, and a rotary drive motor is connected to the top of the support column 331. A movable arm 333 is connected to the output shaft of the rotary drive motor, and an infrared probe 34 is located at the end of the movable free extension end, so as to achieve avoidance in the initial state.
[0044] In specific settings, such as Figure 4 , Figure 5 As shown, the rotary drive unit 332 uses a rotary cylinder, which is set to rotate 90° periodically. In the initial state, the movable arm 333 is parallel to the length direction of the moving tray 32, as shown. Figure 4 As shown, during the test, the movable arm 333 is driven to rotate 90° by the rotary drive unit 332, so that the movable arm 333 is perpendicular to the length direction of the moving tray 32, as shown. Figure 5 As shown, this positions the infrared probe 34 directly above the fixed position of the moving tray 32, enabling testing of the guide rail gauge. Alternatively, the rotary drive unit 332 can also utilize a stepper motor or other methods to achieve rotation.
[0045] Understandably, in the initial state, the test workpiece (guide rail) needs to be installed at a fixed station. If the infrared probe 34 is located above the fixed station, this will increase the difficulty of installing the test workpiece and is not conducive to improving testing efficiency. In this embodiment, through the setting of the movable arm 333 and the rotary drive unit 332, the position of the infrared probe 34 can be automatically adjusted, which is beneficial to the installation of the test workpiece and improves testing efficiency.
[0046] In conjunction with the above embodiments, the free extension end of the movable arm 333 is provided with a fixed cylinder 334, and the infrared probe 34 is fixedly installed inside the fixed cylinder 334. The infrared probe 34 is used to detect the guide rail table within the fixed workstation. The infrared probe 34 needs to have a stable connection structure during the position adjustment process. In this embodiment, the infrared probe 34 is fixed by means of the fixed cylinder 334, which improves the stability of the connection of the infrared probe 34.
[0047] Specifically, the infrared probe 34 is housed within the fixing cylinder 334, and the fixing cylinder 334 is used to fix the infrared probe 34. In practice, the infrared probe 34 can be fixed within the fixing cylinder 334 using a fixing connector. For example, the outer housing of the infrared probe 34 can be fixed within the fixing cylinder 334 by bonding or welding, thus achieving the fixation of the infrared probe 34.
[0048] In a specific embodiment, the inner diameter of the fixing cylinder 334 is slightly larger than the outer diameter of the infrared probe 34, which facilitates the installation of the infrared probe 34. At least one threaded hole is provided on the outer wall of the fixing cylinder 334, and a self-locking screw 335 is provided in the threaded hole. The self-locking screw 335 extends into the fixing cylinder 334 through the threaded hole, and the end of the self-locking screw 335 abuts against the outer wall surface of the infrared probe 34 to fix the infrared probe 34.
[0049] Understandably, using the fixing cylinder 334 makes the installation of the infrared probe 34 more convenient and facilitates subsequent adjustments and maintenance of the infrared probe 34.
[0050] In conjunction with the above embodiments, such as Figure 3 As shown, a sensor switch 221 is fixedly installed on the linear drive device 22. The sensor switch 221 is electrically connected to the rotary drive unit 332. The sensor switch 221 is used to control the rotation of the rotary drive unit 332 under test conditions so that the infrared probe 34 faces the guide rail. The infrared probe 34 is rotated by the rotary drive unit 332. In this embodiment, the sensor switch 221 is set to be linked with the infrared probe 34 for control, realizing automatic position adjustment of the infrared probe 34 and improving the degree of automation.
[0051] Specifically, the inductive switch 221 is located on the side wall of the linear drive device 22. In the initial state, the moving tray 32 is not moving, and the inductive switch 221 is not triggered. Under test conditions, the linear drive device 22 operates and drives the moving tray 32 to move. During this movement, the inductive switch 221 is triggered, thereby actuating the rotary drive device. The inductive switch 221 can be a magnetic inductive switch 221, a capacitive inductive switch 221, an infrared inductive switch 221, etc. The following explanation uses a magnetic inductive switch 221 as an example.
[0052] A magnetic induction switch 221 is mounted on the side wall of a linear drive unit 22, which is a slide cylinder and is located entirely within the installation space 13. The magnetic induction switch 221 is electrically connected to the control solenoid valve of the rotary drive unit 332. After the piston rod on the slide cylinder moves a certain distance, it triggers the magnetic induction switch 221. The magnetic induction switch 221 controls the rotary drive unit 332 to rotate the infrared probe 34 by 90° via the solenoid valve, so that the infrared probe 34 is directly above the guide rail gauge. In specific triggering, a trigger block (such as a magnet) can be set on the piston rod of the slide cylinder. The magnetic induction switch 221 is located at a specific position on the side wall of the slide cylinder. This position allows the moving tray 32 to move until the spring probe abuts against the terminal of the guide rail gauge, at which point the magnetic induction switch 221 triggers to control the rotation of the infrared probe 34, thereby achieving linkage control.
[0053] Understandably, by setting the inductive switch 221, the linkage control of the position adjustment of the infrared probe 34 is realized, thereby improving the automation level of tooling inspection.
[0054] In some embodiments, such as Figure 4 , Figure 5 As shown, the movable tray 32 has a limiting groove 321, and a clamping structure 322 is provided at one end of the limiting groove 321 away from the fixed abutment seat 31. The clamping structure 322 is used to contact and abut with the guide rail gauge. The guide rail gauge needs to have a stable connection position during testing. In this embodiment, the cooperation between the limiting groove 321 and the clamping structure 322 achieves stable installation of the guide rail gauge and improves the stability of the test.
[0055] Specifically, the clamping structure 322 and the end of the limiting groove 321 near the fixed abutment 31 form a limiting space. The guide rail is placed within the limiting space, and a certain pre-tightening force is applied to the guide rail through the action of the clamping structure 322, thereby giving the guide rail a stable connection structure. The clamping structure 322 can be a conventional low-tightness component, such as a pin connection for clamping, or an elastic component such as a spring for clamping.
[0056] In its specific configuration, the clamping structure 322 includes a movable block and a spring positioning pin. The spring positioning pin is fixedly connected to the side wall of the limiting groove 321, and the movable block is connected to the spring positioning pin. The top edge of the movable block facing the fixed abutment seat 31 has a chamfered structure. The combination of the movable block and the spring positioning pin achieves the clamping operation on the guide rail gauge, improving the stability of the guide rail gauge connection.
[0057] Specifically, the spring positioning pin is a telescopic pin shaft, and a return spring is sleeved on the outside of the telescopic pin shaft. The fixed end of the spring positioning pin is connected to the side wall of the limiting groove 321, and the telescopic end of the spring positioning pin is connected to the movable block. Under the action of external force, the movable block can move in the telescopic direction of the spring positioning pin.
[0058] Understandably, the chamfered structure on the movable block facilitates the installation of the guide rail gauge. Specifically, during the installation of the guide rail gauge, it can cooperate with the chamfered structure to push the movable block, causing the movable block to move along the direction of the spring positioning pin, thereby compressing the return spring and achieving stable limiting of the guide rail gauge.
[0059] In conjunction with the above embodiments, such as Figure 6 As shown, a mating groove 312 is provided on the side wall of the fixed abutment 31 facing the movable tray 32, and the power-on spring probe 313 and the test spring probe 314 are disposed in the mating groove 312. The exposure of the spring probes may pose a risk of accidental electric shock. In this embodiment, the mating groove 312 provides a structural barrier, thereby improving the overall safety performance.
[0060] Specifically, both the power-on spring probe 313 and the test spring probe 314 are located within the mating groove 312. The mating groove 312 prevents the spring probes from being exposed during testing, thus improving the safety performance of the fixture. In other words, during testing, the spring probes abut against the terminals inside the guide rail meter, and at this time, part of the guide rail meter's housing is located within the mating groove 312, thereby preventing the spring probes from being exposed.
[0061] In conjunction with the above embodiments, a limiting block 323 is provided at the end of the movable tray 32 facing the fixed abutment seat 31, and the limiting block 323 cooperates with the mating groove 312 to limit the movement. The setting of the limiting block 323 makes the guide rail more stable when it is engaged with the fixed abutment seat 31.
[0062] Specifically, the width of the limiting block 323 matches the width of the groove of the docking groove 312, so that when the moving pallet 32 moves, the limiting block 323 can be inserted into the groove of the docking groove 312 to achieve guidance and prevent the moving pallet 32 from shaking in the width direction, thereby improving the stability of docking.
[0063] In some embodiments, such as Figure 1 , Figure 6 As shown, an indicator light 311 is provided on the fixed abutment 31. The indicator light 311 is used to detect the open / closed status of the relay of the test rail meter. The setting of the indicator light 311 facilitates the feedback of the test results and improves the convenience of the test.
[0064] Specifically, the illumination and deactivation of indicator light 311 can effectively provide feedback on the opening and closing status of the rail meter relay, thereby improving the feedback efficiency of the test.
[0065] The following describes the specific testing steps using the aforementioned guide rail gauge testing fixture.
[0066] Connect an external power consumption tester to the interface 14 on the rear side of the tooling housing 10, turn on the tooling power supply and air supply, connect the infrared probe 34 to the computer host and open the test software, and turn on the tooling power switch.
[0067] Step 1: Place the guide rail meter in the movable tray 32. The back side of the guide rail meter slides down through the chamfer on the movable block. The spring positioning pin retracts and pushes the movable block to press against the back side of the guide rail meter to limit and fix it. Step 2: Press the self-locking button 12. The piston rod inside the linear drive device 22 extends, pushing the moving tray 32 to move, and causing the guide rail meter's wiring terminals to abut against the power-on spring probe 313 and the test spring probe 314. The power-on spring probe 313 and the test spring probe 314 retract and enter the docking groove 312 together with the guide rail meter's wiring terminals. At the same time, the magnetic induction switch 221 on the side of the linear drive device 22 triggers the rotating shaft of the rotary drive unit 332 to rotate 90°. The rotating shaft of the rotary drive unit 332 drives the movable arm 333 to rotate synchronously. This aligns the infrared probe 34 with the guide rail meter's infrared communication window. Simultaneously, the baffle 222 presses against the self-reset button 41, and the power supply inside the tooling box 10 powers the guide rail meter through the power-on spring probe 313. The power consumption tester displays the power consumption current of the guide rail meter. Step 3: Use a handheld barcode scanner to scan the QR code on the guide rail and activate the computer testing software. The testing software establishes communication with the guide rail through the infrared communication window of the infrared probe 34, reads the guide rail information, and performs comparison. Step 4: The test software sets the rail meter relay to close via infrared probe 34, and the rail meter voltage output terminal is connected to the test spring probe 314 to provide voltage to indicator light 311, which then lights up. The test software sets the rail meter relay to open via infrared probe 34, and the rail meter voltage output terminal is connected to the test spring probe 314 without voltage, which then turns off indicator light 311. Step 5: After the guide rail meter test is completed, press the self-locking button 12. The piston rod in the linear drive device 22 retracts and pushes the moving tray 32 to reset. The guide rail meter wiring terminals are disconnected from the power-on spring probe 313 and the test spring probe 314. At the same time, the magnetic induction switch 221 controls the rotary drive unit 332 to reset. The rotation axis of the rotary drive unit 332 rotates the movable arm 333 and the infrared probe 34 back to the edge of the moving tray 32, parallel to its length direction. At the same time, the baffle 222 disengages from the self-reset button 41, the power-on spring probe 313 is de-energized, and the power consumption tester displays that the power consumption current of the guide rail meter is zero.
[0068] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment, through the cooperation of the displacement drive component 20 and the positioning detection component 30, achieves automatic engagement of the power-on spring probe 313 and the test spring probe 314, avoiding manual connection of the guide rail meter terminals. Furthermore, by setting a fixed station on the moving tray 32 for fixing the conductive meter, the stability and efficiency of the test are improved. Automated alignment can be achieved through the infrared probe 34, increasing the degree of automation in the detection, avoiding the risk of electric shock during manual operation, and improving the operational safety of the test personnel. Furthermore, by setting the spring probe within the docking groove 312, rapid docking of the guide rail meter terminals and the spring probe is achieved. Simultaneously, the live metal parts of the tooling are hidden within the docking groove 312, preventing accidental contact by the test personnel. Furthermore, while the guide rail meter's wiring terminals are in contact with the spring probe, the baffle 222 presses against the self-reset button 41 to conduct power to the guide rail meter via the power-on spring probe 313. When the guide rail meter's wiring terminals are no longer in contact with the spring probe, the baffle 222 releases the self-reset button 41, and the power supply to the power-on spring probe 313 is cut off, effectively ensuring the operational safety of the test personnel and improving the testing efficiency of the guide rail meter.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
