Description

Technical Field

[0001] This utility model relates to the testing of power metering instruments, and in particular to a single-board testing fixture for three-phase energy meters, belonging to the technical field of single-board testing equipment. Background Technology

[0002] The three-phase energy meter circuit board testing fixture is a specialized testing device designed for the core printed circuit board of a three-phase energy meter. Its core function is to simulate actual working conditions, apply standard test signals, and collect key electrical parameters and functional responses of the circuit board as a production and quality inspection tool.

[0003] CN222734272U discloses a single-board testing fixture for electricity meters, involving a single board. The fixture includes a receiving base on the outside of a mounting frame, a clamping assembly on a test bench, and a moving assembly on the test bench. The single board is placed face up on the receiving base. The clamping assembly can lift the single board and flip it over. The moving assembly can reciprocate between the clamping assembly and a probe plate. This single-board testing fixture, by setting a receiving base, first places the single board outside the mounting frame. The clamping assembly then lifts it, and the moving assembly moves it, automatically placing the single board onto the probe plate. After testing, the clamping assembly lifts it again, and the moving assembly removes it. This mechanical approach replaces manual alignment, speeding up the process and improving work efficiency. Furthermore, placing the single board face up avoids damage to the front components caused by compression.

[0004] The single-board inspection fixture is not equipped with corresponding top-loading and bottom-loading mechanisms. In actual operation, the inspected single boards need to be removed manually to restore the inspection station to empty. Although the bottom-loading process is simple to operate, when facing a large number of single-board inspection needs, the manual bottom-loading process will become an efficiency bottleneck. If this process can be eliminated, the inspection efficiency can be significantly improved. Therefore, the automated bottom-loading design of this fixture needs to be improved.

[0005] To address this, a single-board testing fixture for three-phase energy meters is proposed. Utility Model Content

[0006] In view of this, the present invention provides a single-board testing fixture for three-phase energy meters to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A single-board testing fixture for a three-phase energy meter includes a testing platform, a top plate mounted on the testing platform, a cylinder mounted on the top plate, a connecting plate mounted on the output end of the cylinder, a buffer rod inserted into the connecting plate, a testing plate connected below the buffer rod via a quick-release mechanism, a buffer spring sleeved on the buffer rod, a slotted seat mounted on the testing platform, a limit groove provided inside the testing platform, a top plate slidably mounted in the limit groove, a bottom plate mounted below the top plate, a support plate mounted on the output end of the cylinder, a horizontal plate mounted below the support plate, a guide rod slidably mounted inside the horizontal plate, a lifting plate connected above the guide rod, a spring sleeved on the guide rod, and a discharge mechanism integrated on the testing platform.

[0008] More preferably, the inner wall of the limiting groove is provided with a vertical sliding groove, and the two sides of the top plate are equipped with protrusion structures adapted to the sliding groove, the protrusion structures being slidably disposed in the sliding groove.

[0009] More preferably, one end of the buffer spring is mounted on the buffer rod, and the other end of the buffer spring is mounted above the connecting plate, and the buffer spring drives the buffer rod to have a vertical downward tendency.

[0010] More preferably, one end of the spring is installed below the lifting plate, and the other end of the spring is installed above the horizontal plate, and the spring drives the lifting plate to have a vertical upward tendency.

[0011] More preferably, the material discharge mechanism includes a fixed rod, a dial plate, a side plate, and an electric push rod. The fixed rod is installed above the detection table, the dial plate is rotatably installed on the fixed rod, the side plate is installed on the dial plate, and the side plate is hinged to the output end of the electric push rod via a rotating shaft.

[0013] More preferably, the T-shaped block and the T-shaped groove are adapted to each other.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. In this utility model, not only can the single board inspection operation be completed efficiently, but the material ejection mechanism and the material discharge mechanism integrated inside the device can work together. During the cylinder retraction process, the material ejection plate can be linked to automatically eject the inspected single board out of the slot. At the same time, the hinge structure between the electric push rod and the deflector plate in the material discharge mechanism can accurately drive the deflector plate to rotate, quickly push the ejected single board away, so that the inspection station in the slot can be quickly restored to an empty state, ready for the next inspection operation, eliminating the manual material unloading process and greatly improving the inspection efficiency.

[0016] Second, in this utility model, by setting up a quick-release mechanism for the detection plate, when the detection plate is damaged or needs replacement and maintenance, simply tighten the four sets of locking nuts to release the clamping limit at the connection between the T-block and the T-slot, and then pull out the detection plate along the T-slot direction for individual maintenance.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model embodiment provides a single-board testing fixture for a three-phase energy meter, including a testing platform 1, a top plate 2 mounted on the testing platform 1, a cylinder 3 mounted on the top plate 2, a connecting plate 4 mounted on the output end of the cylinder 3, a buffer rod 5 inserted into the connecting plate 4, a testing plate 6 connected below the buffer rod 5 via a quick-release mechanism, a buffer spring 7 sleeved on the buffer rod 5, a slot seat 8 mounted on the testing platform 1, a limit groove 9 provided inside the testing platform 1, a top plate 10 slidably mounted inside the limit groove 9, a bottom plate 11 mounted below the top plate 10, a support plate 12 mounted on the output end of the cylinder 3, a horizontal plate 13 mounted below the support plate 12, a guide rod 14 slidably mounted inside the horizontal plate 13, a lifting plate 15 connected above the guide rod 14, a spring 16 sleeved on the guide rod 14, and a discharge mechanism integrated on the testing platform 1.

[0029] In one embodiment, a vertical groove is provided on the inner wall of the limiting groove 9, and protrusion structures adapted to the groove are installed on both sides of the top plate 10. The protrusion structures are slidably disposed in the groove. The groove on the inner wall of the limiting groove 9 and the protrusion structures on both sides of the top plate 10 form a sliding fit, which plays a vertical guiding and limiting role for the top plate 10, ensuring the stability of the initial placement position of the single plate.

[0030] In one embodiment, one end of the buffer spring 7 is mounted on the buffer rod 5, and the other end of the buffer spring 7 is mounted above the connecting plate 4. The buffer spring 7 drives the buffer rod 5 to have a vertical downward tendency. The buffer spring 7 can effectively weaken the contact impact force, avoid damage to the single board components, and at the same time ensure that the detection board 6 and the detection contacts of the single board are in close contact, so as to achieve stable detection of the single board's electrical performance.

[0031] In one embodiment, one end of the spring 16 is installed below the lifting plate 15, and the other end of the spring 16 is installed above the horizontal plate 13. The spring 16 drives the lifting plate 15 to have a vertical upward tendency. The spring 16 not only serves as a load-bearing element but also acts as a buffer, preventing the device from being damaged due to excessive retraction of the cylinder 3.

[0032] In one embodiment, the discharge mechanism includes a fixed rod 17, a lever 18, a side plate 19, and an electric push rod 20. The fixed rod 17 is mounted above the detection table 1, the lever 18 is rotatably mounted on the fixed rod 17, and the side plate 19 is mounted on the lever 18. The side plate 19 is hinged to the output end of the electric push rod 20 via a pivot. When the electric push rod 20 retracts, the lever 18 rotates around the fixed rod 17 due to the hinge with the side plate 19. The rotating lever 18 pushes the ejected single plate away from above the slot seat 8.

[0033] In one embodiment, the quick-release mechanism includes a T-block 21, a stud 22, a T-slot 23, and a locking nut 24. The T-block 21 is installed below the buffer rod 5, the stud 22 is installed above the detection plate 6, the T-slot 23 is disposed within the stud 22, and the locking nut 24 is threaded onto the stud 22. When the detection plate 6 is damaged, the locking nut 24 is turned and moved downwards along the stud 22 to release the clamping limit at the connection point. Then, the detection plate 6 can be pulled out along the T-slot 23 for maintenance.

[0034] In one embodiment, the T-shaped block 21 and the T-shaped slot 23 are adapted to each other. The T-shaped connection not only has high stability, but also makes the insertion method more convenient.

[0035] In operation, the three-phase power supply single board is placed in the slot 8 of the testing platform 1. The cylinder 3 above the top plate 2 is activated, and the output of cylinder 3 synchronously moves the connecting plate 4 and the support plate 12 downwards. As the connecting plate 4 moves downwards, the buffer rod 5 moves downwards simultaneously. The testing plate 6 below the buffer rod 5 gradually approaches the single board in the slot 8. When the testing plate 6 contacts the single board, the buffer spring 7 effectively weakens the contact impact force, preventing damage to the single board components. Simultaneously, it ensures a tight fit between the testing plate 6 and the testing contacts of the single board, achieving stable testing of the single board's electrical performance. After the single board testing is completed, the output of cylinder 3 drives the connecting plate 4 and the support plate 12 to rise synchronously upwards. When the support plate 12 rises, the horizontal plate 13 moves upwards accordingly, and simultaneously drives the lifting plate 15 to move vertically upwards. The lifting plate 15 pushes the bottom plate 11 upwards, and the bottom plate 11 drives the top plate 10 to move vertically upwards along the sliding groove of the limiting groove 9. The top plate 10 pushes the single board that has been inspected in the slot 8 upwards, so that the single board is removed from the limiting position of the slot 8. Then the discharge mechanism is started. The output end of the electric push rod 20 drives the side plate 19 to move through the rotating shaft. The electric push rod 20 retracts. Under the hinge action with the side plate 19, the lever 18 will rotate around the fixed rod 17. The rotating lever 18 pushes the ejected single board away from above the slot 8, so that the inspection position in the slot 8 is quickly restored to empty, which is convenient for the inspection operation of the next single board.

[0036] When the detection plate 6 is damaged or needs to be replaced, tighten the locking nut 24 on the stud 22. The locking nut 24 moves downward along the stud 22 under the action of the thread, releasing the tightness limit at the connection between the T-block 21 and the T-slot 23. Then, the detection plate 6 can be pulled out along the direction of the T-slot 23 for separate maintenance. After maintenance, insert the T-block 21 into the T-slot 23, and then tighten the locking nut 24 in the opposite direction, so that it moves upward along the stud 22 under the action of the thread and re-tightens the connection between the T-block 21 and the T-slot 23, thereby completing the installation and fixing of the detection plate 6.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
