Technical Field
[0001] The utility model relates to a motor clamping tooling for a dynamometer. Background Art
[0002] In the prior art, the dynamometer test of the motor is sometimes arranged before riveting the fuselage and the motor cover.

[0016] Unless otherwise defined, the meanings of all technical and scientific terms used herein are the same as those commonly understood by those of ordinary skill in the art. In case of conflict, the description and definition herein shall prevail.
[0017] In order to meet the trend that the existing motor will be riveted to the body and the cover before dynamometer testing, and to solve the defect that the cover will become loose from the body in this dynamometer testing method, the present utility model provides a motor clamping tooling for a dynamometer, which is used to clamp the body and the cover of the motor. Its structure mainly includes:
[0018] A base, the base has an abutting part for abutting against the surface of the cover, the abutting part has a test hole, and the dynamometer performs dynamometer testing on the motor through the test hole.
[0019] A pushing device, which is used to push the body, and the pushing device cooperates with the abutting part to clamp the body and the cover.
[0020] During dynamometer testing, the pushing device and the base can cooperate to clamp the body and the cover. Specifically, the cover abuts against the abutting part of the base, and the pushing device pushes the body towards the cover, so that the body and the cover are clamped before being riveted. And the connecting head of the dynamometer is connected to the motor through the test hole on the abutting part for dynamometer testing. During the dynamometer testing process, the abutting part and the pushing device keep clamping the body and the cover, thereby preventing the cover from falling off during the dynamometer testing process.
[0021] Hereinafter, the present utility model will be further described in conjunction with specific embodiments.
[0022] Figure 1 Shows a specific structure of the motor clamping tooling for a dynamometer, and its structure includes a base and a cylinder mechanism. The base structure includes a bottom plate 7 that can be fixed by the dynamometer workbench. The bottom plate 7 is a rectangular metal table body, and there are edges reserved on both sides of the metal table body for fastening with the bolt fasteners of the dynamometer workbench. Refer to Figure 2 , when fixing, place the edge of the metal table body under the bolt fastener, and after tightening the bolt, the bottom plate can be clamped and fixed together with the surface of the workbench. On the other side symmetric to the bottom plate, according to Figure 2In the same way, fastening can also be carried out. A supporting member 4 is arranged above the bottom plate. The supporting member 4 is a relatively small metal table body, and its upper part has a surface that fits the side surface of the motor body. In this embodiment, the supporting member has a concave arc surface for fitting a motor with a cylindrical body. The motor lies horizontally on this surface of the supporting member and is thus limited and placed relatively stably, providing a good basis for subsequent clamping. A butting member 5 is arranged on the front side of the bottom plate. The butting member is a metal plate body. A circular test hole 6 is opened on the butting member. The butting member is also provided with a first limiting surface that fits and limits the surface of the motor cover. When the motor lies horizontally on the supporting member 4, the motor cover can be restricted by the first limiting surface on the butting member, and the output end of the motor is located in the test hole. A connecting member 9 is arranged on the rear side of the bottom plate. The connecting member is a metal plate body and is used to fix the pushing device. The pushing device includes a cylinder mechanism and a pushing member 3. When the motor lies horizontally on the supporting member 4, the driving member can push the body of the motor towards the butting member 5 from the end of the motor to press the body and the cover together. Among them, the cylinder mechanism includes a cylinder 2 and a manual valve 1. Operating the manual valve can control the movement of the cylinder. The piston rod in the cylinder passes through the through hole 10 and is connected to the pushing member 3. After the cylinder is fixed on the connecting member 9, its reciprocating direction is fixed to be the same as the axial direction of the motor shaft.
[0023] Thus, when it is necessary to measure the power of an unriveted motor, first fix the motor clamping tooling structure on the workbench of the dynamometer according to the Figure 2 method. Then, referring to the state when the motor is riveted, hold the motor by the surface of the motor cover and the end of the body, place the motor horizontally on the supporting member 4, insert the front end with the output shaft into the test hole 6, and the motor cover is cooperatively limited by adjusting the overall position of the motor to closely lean against the limiting surface of the butting part. At this time, operate the manual valve to make the piston rod 11 extend. The piston rod pushes the pushing member 3 until it touches the end of the body, and then continue to finely adjust the manual valve to make the piston rod extend further by 11 to ensure that the body and the cover are in a pressed state. Then, the connector of the dynamometer can be installed on the motor output shaft for power measurement. Only the motors that pass the power measurement are subjected to subsequent riveting of the motor cover and the body. This saves costs.
[0024] The embodiments in the present utility model are only used to illustrate the present utility model and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be thought of by those skilled in the art are all within the protection scope of the present utility model.
