Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a motor testing tool. Background Art

[0002] In the manufacturing process of new energy motors, self-inspection after assembly is an indispensable step. It helps to promptly detect problems that may occur during the installation process, such as bore scraping or foreign objects, and ensures that the motor has good initial quality before delivery and testing.

[0003] The prior art discloses a new energy motor detection device, the publication number of which is CN220730273U. The device includes components such as a main board, a card strip, a slide groove, a positioning plate, a clamping plate, a positioning groove and a positioning block. Through the interaction of these components, stable clamping and positioning of the motor are achieved.

[0004] The design of this device allows workers to pull the adjustment block to drive the positioning rod and positioning block to move, thereby removing the positioning plate, making it easier to replace and maintain the clamping plate.

[0005] However, although this design shows a certain convenience in clamping and positioning the motor, it does not involve the detection of problems such as bore sweeping or foreign objects during the motor self-inspection process. In order to solve this problem, a new type of tooling needs to be designed. Utility Model Content

[0006] In order to solve the above-mentioned technical problem or one of the technical problems existing in the prior art, the utility model discloses a motor testing tool, including a handle and a connecting shaft, one end of the connecting shaft is fixedly connected to one end of the handle, and the other end is fixedly connected to a test head, the test head is cylindrical, and a circular array of tooth-like protrusions on its outer circumference is provided, the tooth-like protrusions are arranged along the length direction of the shaft, and grooves are provided between the tooth-like protrusions.

[0007] Furthermore, the tooth-shaped protrusion is rectangular.

[0008] Furthermore, the handle, the connecting shaft and the test head are all coaxially connected.

[0009] Furthermore, the handle is in the shape of a hexagonal column.

[0010] Furthermore, a groove is provided at the center of the top of the test head, a vibration sensor is installed in the groove, and a screw is provided above the vibration sensor and is screwed to the side wall of the groove.

[0011] Furthermore, a warning light is provided on the handle, and the warning light is electrically connected to the vibration sensor.

[0012] Furthermore, there are two warning lights, including a red warning light and a green warning light, both of which are fixed to the outer side wall of the handle.

[0013] Compared with the existing technology, the present invention firmly fixes the handle and the test head together to form an integrated test tool. This design not only provides the stability and force transmission efficiency required during operation, but also ensures that the test head can accurately match the internal splines of the motor.

[0014] The cylindrical design of the test head and the tooth-like protrusions on the outer surface enable it to be tightly inserted into the internal splines of the motor. The tooth-like protrusions are arranged in an orderly manner along the length of the shaft. This layout can effectively grasp the internal splines of the motor and achieve stable rotation.

[0015] The operator can simply turn the handle to make the motor perform a simple rotation test. This rotation test is an intuitive and effective method to determine whether there is a bore scraping or other adverse conditions inside the motor. If the motor has abnormal vibration, noise or resistance during rotation, it may indicate that there is a problem inside the motor and further inspection or repair is required.

[0016] Furthermore, the tooling is simple and intuitive, easy to operate, and requires no complex setup or adjustments, allowing even non-professionals to quickly master and perform motor inspections. Its ease of use and efficiency make it particularly suitable for batch inspections on production lines, significantly improving inspection speed and efficiency while also reducing labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 The technical solution adopted by the utility model shown is: a motor testing tool, including a handle 1 and a connecting shaft 2, one end of the connecting shaft 2 is fixedly connected to one end of the handle 1, and the other end is fixedly connected to a test head 3, the test head 3 is cylindrical, and a circular array of tooth-like protrusions 4 on its outer circumference is arranged along the length direction of the shaft, and grooves 5 are provided between the tooth-like protrusions 4.

[0020] Preferably, the tooth-shaped projections 4 are rectangular, providing a larger contact area and more uniform stress distribution. They also correspond to the shape of the motor's internal splines, making the fit between the projections and the internal splines more precise, helping to improve the reliability and repeatability of rotation testing. The rectangular tooth-shaped projections' right-angled edges also provide better positioning on the motor's internal splines, reducing errors caused by improper clamping.

[0021] Preferably, the handle 1, connecting shaft 2, and test head 3 are all coaxially connected. This coaxial connection ensures linear force transmission, reducing force offset and torque loss. This design allows the operator's force applied to the handle to be directly and effectively transmitted to the test head, thereby achieving more precise control during motor rotation testing. The coaxial structure also helps maintain the stability of the tooling, avoiding unnecessary vibration or offset during testing, which is crucial for accurately detecting the motor's rotational performance.

[0022] Preferably, the handle 1 is in the shape of a hexagonal column, which provides a larger gripping area and better grip comfort. This shape of handle can provide uniform gripping force in multiple directions, allowing the operator to more stably control the tooling when performing motor testing. In addition, the edge of the hexagonal column handle can serve as a fulcrum for a lever, allowing the operator to apply force more effectively when needed.

[0023] Preferably, a groove 31 is provided at the center of the top of the test head 3, which is an installation space so that the vibration sensor can be fixed at the center position inside the test head. The vibration sensor is installed in the groove 31 to detect and measure the vibration generated during the test, which is crucial for evaluating the performance and stability of the test object. The battery is located below the vibration sensor, and a screw 32 is provided above the vibration sensor, which is screwed to the side wall of the groove 31 and is used to limit and protect the vibration sensor.

[0024] Preferably, a warning light 11 is provided on the handle 1, and a battery cavity and a battery are provided at the bottom of the handle 1. The battery is electrically connected to the warning light 11, which can quickly remind the operator to pay attention to problems that may occur during the test, so that timely measures can be taken. The warning light 11 is electrically connected to the vibration sensor, ensuring that the warning light can be activated according to the vibration signal detected by the vibration sensor, realizing a real-time feedback mechanism, so that the operator can judge whether the test is normal according to the signal of the warning light.

[0025] Preferably, there are two warning lights 11, including a red warning light and a green warning light. The color change can be triggered by the signal detected by the vibration sensor to achieve real-time feedback. Through lights of different colors, the operator can quickly identify the status of the test head without complicated interpretation or additional information. They are all fixed to the outer wall of the handle 1, making the warning lights easy to observe, because the handle is the part that the operator most often touches and checks when operating the test head.

[0026] How to use: insert the top into the spline inside the motor, then the worker turns the bottom to make the motor rotate simply. When the vibration is within the normal range, the green warning light is activated by the vibration sensor. When the vibration is abnormal, the red warning light is activated by the vibration sensor to determine whether there are any defects such as bore scraping inside the motor. After the test, the motor is handed over for testing to perform a system test.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
