Description

Technical Field

[0001] The utility model relates to the field of test auxiliary equipment, in particular to a switch test auxiliary tool. Background Art

[0002] The switch test auxiliary tool aims to improve the efficiency and accuracy of switch testing. Through automated operations, precise measurements, and data analysis, it ensures that the switch can achieve the expected performance and lifespan under various conditions.

[0003] For the switch test auxiliary equipment, it is a specific stroke to reciprocally push the roller in an automated control manner to simulate the actual movement of the switch and perform repeated switch operations. Multiple switches are fixed by a fixture for simultaneous testing to improve efficiency. However, there will be a gap between two switches. When the roller reciprocates, there will be a forward and backward force. If no additional fixing measures are taken, the existing gap may cause the two switches to displace within the fixture under the push of the roller. For this reason, a switch test auxiliary tool is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a switch test auxiliary tool. Through the provided interval positioning plate, it presses on one side of the upper surface of the switch cover plate and is located beside the test wheel to restrict the test wheel to move only between the test plate and the interval positioning plate, thereby further fixing each switch and avoiding the problem of switch displacement within the movable clamp and the fixed clamp when there is a gap between two switches.

[0005] In order to solve the above technical problems, the utility model solves the problem that the existing gap may cause the two switches to displace within the fixture when the switch test auxiliary tool operates without taking additional fixing measures.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A switch test auxiliary tool includes a test auxiliary tooling. Multiple test plates with test wheels are arranged on the test auxiliary tooling for testing switches. The switches are fixed by a movable clamp and a fixed clamp, and an interval positioning plate is provided thereon for limiting.

[0008] Preferably, the movable clamp and the fixed clamp are fixed on the test auxiliary tooling through a fixture seat, and an adjusting rotating rod is provided on the fixture seat to make the movable clamp move relatively.

[0009] Preferably, multiple test plates are connected by a push plate, and a control mechanism is provided at one end of the push plate away from the test plate to control the forward and backward movement.

[0010] Preferably, a base is provided at the bottom of the control mechanism for connecting with the test auxiliary tooling, and one end of the control mechanism for controlling the extension of the hydraulic rod is connected to the push plate.

[0011] Preferably, one end of the interval positioning plate can extend from the sides of the test plate and the test wheel to the upper surface of the fixed clamping plate.

[0012] Preferably, a support fixing rod is connected to the other end of the interval positioning plate.

[0013] Preferably, a plurality of adjustment notches are formed inside the push plate to allow the support fixing rod to pass through. One end of the support fixing rod passing through the adjustment notch is provided with a thread and is connected with a nut in a matching manner.

[0014] Preferably, the test plate pushes the test wheel to roll back and forth on the cover plate of the switch. The interval positioning plate can be pressed on the upper surface of the switch cover plate, and the test wheel is located between the test plate and the interval positioning plate to move.

[0015] Preferably, a suction cup with a compression spring is arranged at one end of the interval positioning plate away from the support fixing rod and is pressed on the upper surface of the fixed clamping plate.

[0016] Preferably, a fixing plate and a stable sleeve block are installed at one end of the interval positioning plate away from the support fixing rod. A connecting rod is arranged on the suction cup and can move inside the stable sleeve block. One end of the compression spring is connected to the connecting rod, and the other end is connected to the fixing plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] For the switch test auxiliary tool provided in this application, through the arranged interval positioning plate, it is pressed on one side of the upper surface of the switch cover plate and is located beside the test wheel to limit the test wheel to move only between the test plate and the interval positioning plate, so as to further fix each switch. When there is a gap between two switches, the problem of the switch generating displacement in the movable clamping plate and the fixed clamping plate is avoided.

[0019] In this application, by setting the push plate and the control mechanism, multiple arranged test plates can be installed on the push plate. While forming an integral body, after the extension end of the hydraulic rod of the control mechanism is connected to the push plate, the control mechanism is manipulated to drive the telescopic movement of the hydraulic rod to push the push plate back and forth, thereby driving the test plates with test wheels on the push plate to move simultaneously.

[0020] In this application, by setting the support fixing rod and the adjustment notch, one end of the support fixing rod passing through to the outside of the adjustment notch is provided with a thread, and it is locked on the push plate through a nut. The design that the support fixing rod can pass through and move left and right therein can be used to adjust the left and right positions of the interval positioning plate to meet more requirements.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , the switch test auxiliary tool of the present application mainly consists of structures such as a test auxiliary tooling 1, a test plate 101, a test wheel 102, a movable clamping plate 2, and a fixed clamping plate 201 to complete the test of the switch. The test plate 101 is connected to the test wheel 102 to push the switch button fixed between the movable clamping plate 2 and the fixed clamping plate 201. When controlling the test plate 101 to push the test wheel 102 to press the button and roll on the switch cover plate, through the provided interval positioning plate 103, it presses on one side of the upper surface of the switch cover plate and is located on the side of the test wheel 102 to limit the test wheel 102 to only move between the test plate 101 and the interval positioning plate 103, so as to further fix each switch. When there is a gap between two switches, it avoids the problem of the switch generating displacement in the movable clamping plate 2 and the fixed clamping plate 201.

[0035] In this application, a fixture base 3 and an adjusting rotating rod 301 are also provided. The fixture base 3 has an interval through which the adjusting rotating rod 301 is installed therein through a bearing.
