Description

Technical Field

[0001] The utility model relates to the field of electric power equipment, in particular to an air switch testing fixture. Background Art

[0002] When using the existing air switch test fixture, the air switch is usually placed on the surface of the clamping seat, and the clamping plates on both sides of the clamping seat are moved inward to fit the surface of the air switch, thereby completing the clamping of the air switch. However, in actual use, since the length of the clamping plates is fixed, but the sizes of air switches are different, when the length of the clamping plates is not enough and cannot fit the surface of the air switch, the air switch cannot be clamped, which brings trouble to the staff. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an air switch testing fixture.

[0004] The purpose of the utility model is achieved through the following technical solutions: an air switch test fixture, comprising:

[0005] A primary clamping mechanism, the primary clamping mechanism comprising a mounting housing and two telescopic arm assemblies respectively disposed on both sides of the mounting housing, the two telescopic arm assemblies being disposed opposite to each other;

[0006] A secondary clamping mechanism, the secondary clamping mechanism includes two clamping assemblies corresponding to the two telescopic arm assemblies, the clamping assembly includes a mounting seat arranged at the telescopic end of the telescopic arm assembly, a driving motor and forward and reverse threaded rods arranged on the mounting seat, and two clamping blocks threadedly connected to the two ends of the forward and reverse threaded rods respectively, the forward and reverse threaded rods are arranged perpendicular to the telescopic direction of the telescopic arm assembly and are rotatably connected to the mounting seat, the power output end of the driving motor is transmission-connected to the forward and reverse threaded rods, and the clamping blocks are used to clamp the air switch.

[0007] The utility model is provided with a primary clamping mechanism and a secondary clamping mechanism, and the secondary clamping mechanism is arranged on the primary clamping mechanism, and the spacing between the two clamping assemblies in the secondary clamping mechanism is adjusted by the primary clamping mechanism. After adjusting the spacing between the two clamping assemblies according to the model size of the air switch, the rotation of the driving motor is controlled to rotate the positive and negative threaded rods on the clamping assembly, so that the clamping blocks threadedly connected at both ends of the positive and negative threaded rods move toward the center of the positive and negative threaded rods to clamp the air switch. Through the primary clamping mechanism and the secondary clamping mechanism, the clamp can adapt to air switches of various models and sizes.

[0008] In some embodiments, the telescopic arm assembly includes a telescopic rod and a push rod. The telescopic rod is fixedly mounted within the mounting housing. The push rod is disposed perpendicular to the telescopic rod. The middle portion of the push rod is connected to the telescopic end of the telescopic rod. The mounting base is connected to both ends of the push rod. By disposing the push rod at the end of the telescopic rod and connecting both ends of the push rod to the mounting base, the connection between the mounting base and the telescopic arm assembly is more stable.

[0009] In some embodiments, the push rod is provided with bosses at both ends, and the top plate of the mounting housing is provided with slots corresponding to the bosses. The length of the slots aligns with the extension and retraction direction of the telescopic rod. The bosses extend through the top plate of the mounting housing through the slots, and the ends of the mounting base are connected to the top ends of the two bosses.

[0010] In some embodiments, a first chute is provided on the bottom plate of the mounting housing, the length of the first chute aligning with the extension and retraction direction of the telescopic rod. A first slider is provided at the bottom of the push rod, slidably connected to the first chute. The first chute and the first slider guide the push rod during movement, preventing the telescopic rod from guiding the push rod during extension and retraction, thereby extending the life of the telescopic rod.

[0011] In some embodiments, the mounting base is provided with end plates at both ends, and the ends of the forward and reverse threaded rods are rotatably connected to the two end plates respectively. The drive motor is disposed on the end plates, and the power output end of the drive motor is drivingly connected to the ends of the forward and reverse threaded rods. The end plates at both ends of the mounting base ensure a stable rotational connection between the forward and reverse threaded rods and the mounting base, while also providing a mounting surface for the drive motor.

[0012] In some embodiments, a clamping plate is provided on one side of the clamping block, and flexible pads are provided on opposite sides of the clamping plates of the two clamping blocks threadedly connected at both ends of the same forward and reverse threaded rod. The provision of the clamping plate provides a larger contact surface between the clamping assembly and the air switch, thereby improving the stability of the clamping.

[0013] In some embodiments, a side plate is provided on the mounting base away from the clamping plate of the clamping block, a second slide groove is provided on a side of the side plate facing the clamping block, and a second slider is provided on the clamping block to be slidably connected to the second slide groove. The second slide groove and the second slider serve as guides during the movement of the clamping block, ensuring smooth movement of the clamping block.

[0014] In some embodiments, the device further includes a base comprising a housing and a base motor disposed within the housing. A power output shaft of the base motor is vertically disposed and extends through the top of the housing. The mounting housing is connected to the top end of the power output shaft of the base motor. The base allows the primary and secondary clamping mechanisms to rotate horizontally, thereby rotating the air switch to adjust the test angle of the air switch.

[0015] In some embodiments, the box body is provided with a heat dissipation vent, and a dustproof net is provided on the heat dissipation vent to prevent dust from accumulating in the box body.

[0016] In some embodiments, the bottom of the box is provided with a plurality of support legs, and the bottoms of the support legs are provided with anti-skid pads. By providing the anti-skid pads on the support legs, the test fixture is prevented from sliding and the stability is improved.

[0017] The utility model has the following advantages:

[0018] 1. Through the primary clamping mechanism and the secondary clamping mechanism, the secondary clamping mechanism is set at the action end of the primary clamping mechanism, so that the spacing of the clamping components in the secondary clamping mechanism can be adjusted, so that the secondary clamping mechanism can adapt to air switches of different models and sizes. After adjusting the spacing of the clamping components, use the clamping components to clamp and fix the air switch.

[0019] 2. By setting up the base, the primary clamping mechanism and the secondary clamping mechanism can be rotated as a whole, so that the air switch clamped and fixed by the primary clamping mechanism and the secondary clamping mechanism can be rotated, which is convenient for adjusting the test angle of the air switch and convenient for staff to observe.

[0031] During use of this embodiment, the two telescopic arm assemblies 2 are first extended and retracted to adjust the distance between the two clamping assemblies 3 located at the telescopic ends of the two telescopic arm assemblies 2 to adapt to air switches of different models and sizes. After the distance between the clamping assemblies 3 is adjusted, the driving motor 33 is used to drive the forward and reverse threaded rods 32 to rotate. After the forward and reverse threaded rods 32 rotate, the two clamping blocks 34 threadedly connected to the two ends of the forward and reverse threaded rods 32 move toward each other to clamp the air switch. After the two clamping assemblies 3 clamp the air switch, the clamping of the air switch is completed.
