Description

Technical Field

[0001] The invention relates to a metal tube type brake resistor testing station. Background Art

[0002] Metal tube type brake resistors need to be tested after production before they can leave the factory. During the factory test, the metal tube type brake resistors need to be fixed with a special bracket before they can be powered on for testing. However, a special bracket can only be adapted to one type of metal tube type brake resistor. Since there are many types of metal tube type brake resistors, multiple brackets are required to correspond to multiple types. On the one hand, this increases the testing cost, and on the other hand, it takes up space in the factory. Summary of the invention

[0003] The present invention aims to improve the deficiencies in the prior art and provides a universal testing station suitable for metal tube type brake resistors of different lengths and shapes.

[0004] To this end, a metal tube type brake resistor testing station is provided, comprising a plurality of linear guide rails arranged at equal intervals, each linear guide rail being equipped with a plurality of horizontal sliders capable of sliding horizontally along the linear guide rails, a fixed column and a vertical slider being arranged above each horizontal slider, the fixed column standing on the horizontal slider, a vertically arranged dovetail groove being opened on the side wall of the fixed column, the vertical slider being provided with a dovetail tenon, a metal fixing hook for supporting the metal tube type brake resistor being arranged at the bottom of the vertical slider, the dovetail tenon and the dovetail groove being interference fit, so that when the metal fixing hook supports the metal tube type brake resistor, the vertical slider can remain stationary by relying on the friction between the fixed column and the fixed column and can slide along the fixed column only under external force operation, and the side wall of the vertical slider has a metal connector extending out of the wall surface, and the metal connector is electrically connected to the metal fixing hook.

[0005] Furthermore, the bottom of the linear guide rail is attached and fixed to the external test tabletop to prevent the middle section from sinking and bending.

[0006] Furthermore, the horizontal sliding block is vertically placed on the top of the linear guide rail and is embedded in the linear guide rail through a dovetail structure.

[0007] Furthermore, the opening of the metal fixing hook faces a direction away from the fixing column.

[0008] Furthermore, the metal connecting piece is specifically a screw.

[0009] Furthermore, there are multiple vertical sliders above each horizontal slider, and each vertical slider is provided with a dovetail to be inserted into a dovetail slot of the same fixed column.

[0010] Furthermore, an insulating base is fixedly attached to the top of the horizontal sliding block, and the fixing column stands upright on the top of the insulating base.

[0011] Furthermore, the linear guide rail has a plurality of mounting holes along its length direction.

[0012] Beneficial effects:

[0013] The test station of the present invention can fix the metal tube type brake resistor without screws, so as to achieve the purpose of convenient placement and removal. By arranging horizontal and vertical guide rail sliders, it can adapt to metal tube type brake resistors of different lengths and shapes, so as to achieve universal use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is further described using the accompanying drawings, but the embodiments in the accompanying drawings do not constitute any limitation to the present invention. A person skilled in the art can obtain other drawings based on the following drawings without creative work.

[0015] Figure 1 It is a structural schematic diagram of the test station of the present invention;

[0016] Figure 2 This is an enlarged view of the structure above the horizontal slider in the test station. DETAILED DESCRIPTION

[0017] The present invention is further described in conjunction with the following examples.

[0018] The test station of this embodiment is as follows Figure 1 As shown, it includes a plurality of linear guide rails 1, each linear guide rail 1 is arranged at equal intervals and placed horizontally, so as to facilitate the adjustment of the length of the work station and adapt to metal tube type brake resistors A of different lengths.

[0019] The bottom of each linear guide 1 is tightly fixed to the test table to prevent the middle section from sinking and bending. Each linear guide 1 is equipped with multiple horizontal sliders 2, which are vertically placed on the top of the linear guide 1 and fit with the linear guide 1 through a dovetail structure, so that they can slide horizontally along the linear guide 1. The linear guide 1 has multiple mounting holes along its length. After the horizontal slider 2 is moved to different mounting holes, the horizontal slider 2 can be fixed to the corresponding mounting holes by bolts, so that the distance between each horizontal slider 2 on the same linear guide 1 is fixed to each other, so as to adapt to supporting metal tube brake resistors of different lengths.

[0020] See Figure 2 The top of the horizontal slider 2 is flush with the top, and an insulating base 3 is fixed on it. A fixing column 4 is erected on the insulating base 3. The side wall of the fixing column 4 is provided with a vertical dovetail groove 41. The vertical slider 5 is provided with a dovetail tenon (not shown in the figure) which is inserted into the dovetail groove 41 to achieve embedding.

[0021] A metal fixing hook 51 is provided at the bottom of the vertical slider 5 . The opening of the metal fixing hook 51 faces a direction away from the fixing column 4 . The metal fixing hook 51 is used to support the tap or fin of the metal tube type brake resistor A.

[0022] The dovetail tenon of the vertical slider 5 is interference fit with the dovetail slot 41, so that when the metal fixing hook 51 supports the metal tube type brake resistor A, the vertical slider 5 can remain stationary by relying on the friction between the fixing column 4, and can only slide vertically along the dovetail slot 41 under a certain degree of external force, so as to adapt to metal tube type brake resistors A of different widths. The width refers to the distance between the upper and lower segments of the metal tube type brake resistor A.

[0023] The side wall of the vertical slider 5 has a screw 52 extending out of the wall as a metal connector. The screw 52 is electrically connected to the metal fixing hook 51. The screw 52 is connected to the test end of the test instrument with an electric wire, so that the test end can be electrically contacted with the tap of the metal tube type brake resistor A.

[0024] The test station of this embodiment can fix the metal tube type brake resistor A without screws, so as to achieve the purpose of convenient placement and removal. By setting horizontal and vertical guide rail sliders, it can adapt to metal tube type brake resistors A of different lengths and shapes, so as to achieve universal use.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, rather than to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present application.
