Description

Technical Field

[0001] This utility model relates to the field of test vehicles, specifically a vehicle for elasticity testing. Background Technology

[0002] The brush holder is a key component in DC or AC commutator motors, used to secure the brushes and ensure stable contact pressure between them and the commutator (or slip rings). The appropriateness of the spring force directly affects the motor's performance, lifespan, and reliability; therefore, a spring force testing fixture is needed. Current spring force testing fixtures suffer from incompatibility due to differences in the structure of motor brush holders, thus requiring improvement. Utility Model Content

[0003] The purpose of this invention is to provide a vehicle for elasticity testing to solve the problems mentioned in the background art. It has the advantages of being adaptable to various vehicles and having adjustable height.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a carrier for elasticity testing, comprising an upper base, a dovetail base movably connected above the upper base, a limiting member restricting the vertical movement of the dovetail base on the upper base, an adjusting member driving the vertical movement of the dovetail base on the upper base, a dovetail body on the dovetail base, a torque meter fixing mechanism fixedly connected to the upper side of the dovetail body, a carrier hole on the upper base, and a product carrier connected to the upper base through the carrier hole.

[0005] Preferably, the torque meter fixing mechanism includes a connecting plate, a torque frame is fixedly connected to the side of the connecting plate, and a torque meter is disposed below the torque frame.

[0006] Preferably, a support column is fixedly connected to the lower side of the upper base, and a lower base is fixedly connected to the lower end of the support column.

[0007] Preferably, the limiting component includes a linear bearing fixedly connected to the upper base, a linear optical axis passing through the linear bearing, a spring sleeved on the linear optical axis, and a limiting plate fixedly connected to the end of the linear optical axis away from the spring.

[0008] Preferably, the adjusting component includes an adjusting screw, which is threadedly connected to a nut located on one side of the upper base.

[0009] Preferably, a fixing screw is provided at the bottom of the dovetail platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The carrier is designed with a screw fixing method for height adjustment, which can be used to switch between different products for testing. The upper base is provided with carrier holes for the product, which facilitates switching and positioning.

[0012] 2. By utilizing the universality of the carrier hole design on the upper base, the product carrier can be designed using round holes among a wide variety of motor brush holders. Once confirmed by the design center, this solves the problem of the inability to share force measuring carriers due to different structures when measuring force in motor brush holders, greatly improving the product management cost.

[0017] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In this embodiment of the utility model,

[0019] A vehicle for elasticity testing, such as Figures 1-3 As shown, the device includes an upper base 2, on which a dovetail base 10 is movably connected. The upper base 2 is provided with a limiting member to restrict the vertical movement of the dovetail base 10, and an adjusting member to drive the vertical movement of the dovetail base 10. A dovetail body 11 is provided on the dovetail base 10, and a torque meter 14 fixing mechanism is fixedly connected to the upper side of the dovetail body 11. The upper base 2 is provided with a carrier hole 15, and a product carrier 16 is connected to the upper base 2 through the carrier hole 15.

[0020] The torque meter 14 fixing mechanism includes a connecting plate 12, a torque frame 13 is fixedly connected to the side of the connecting plate 12, and a torque meter 14 is disposed below the torque frame 13.

[0021] A support column 3 is fixedly connected to the lower side of the upper base 2, and a lower base 1 is fixedly connected to the lower end of the support column 3.

[0022] The limiting component includes a linear bearing 4 fixedly connected to the upper base 2, a linear optical axis 5 passing through the linear bearing 4, a spring 8 sleeved on the linear optical axis 5, and a limiting plate 17 fixedly connected to the end of the linear optical axis 5 away from the spring 8.
