DETAILED DESCRIPTION

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In the event of a conflict, the descriptions and definitions herein shall prevail.

[0025] In view of the fact that the motor clamping tooling in the prior art is large in size and difficult to adjust the angle during noise detection, as well as the problem of complicated clamping process, the present invention provides a detachable motor clamping tooling, comprising:

[0026] The clamp comprises a first clamping arm, a second clamping arm and an elastic mechanism, wherein the first clamping arm and the second clamping arm clamp the motor by elastic force provided by the elastic mechanism,

[0027] The driving device has a connecting mechanism that can move in the same direction or in the opposite direction along the elastic force,

[0028] in,

[0029] The first clamping arm has a rod portion, and a limited end is arranged on the rod portion.

[0030] The connecting mechanism has a movable groove, the movable groove has an opening and a limiting surface, the rod and the limiting end are placed in the movable groove through the opening and can move along the rod in the movable groove to abut against or leave the limiting surface.

[0031] When the connecting mechanism moves in the opposite direction relative to the elastic force, the limiting end is abutted against the limiting surface by the elastic force; when the connecting mechanism moves in the same direction relative to the elastic force, the limiting end stops moving and leaves the limiting surface after the first clamping arm contacts the motor.

[0032] In the above structure, the clamp can be separated from other parts as a separate part after clamping the motor. The cleverness lies in that when the connecting mechanism in the driving mechanism moves in the reverse direction along the elastic force, the limit end in the first clamping arm abuts against the abutment surface in the movable groove of the connecting mechanism, thereby realizing the connection between the clamp and the driving device, and when the connecting mechanism moves in the forward direction along the elastic force, once the second clamping arm contacts the surface of the motor, it stops moving. At this time, the connecting mechanism continues to move, and the limit end leaves the abutment surface. At this time, the clamp can be taken out from the opening of the movable groove and the angle can be adjusted separately for noise detection. This makes the clamping operation easier and also makes it easier to detect noise.

[0033] The present invention is further described below in conjunction with specific embodiments.

[0034] Figure 1 The specific structure of a detachable motor clamping tool is shown. The bottom part is a stop base 300, which includes a stop part 310. The clamp body is placed on Figure 1 The middle stop base is located at the left side of the stop portion, and the driving device is fixed at the right side of the stop portion.

[0035] The clamp clamps the motor along the motor axis. The bottom of the clamp is the motor base 130, which has a supporting portion 131. In the figure, a second clamping arm 110 is fixed on the left side of the motor base, and a connecting plate for connecting an elastic mechanism 140 is fixed on the right side. The elastic mechanism is connected to a first clamping arm 120. A first opening 111 is provided on the first clamping arm 110. The first clamping arm is provided with a limiting surface 112 that matches the surface of the motor cover along the circumference of the first opening. The motor can be placed horizontally on the supporting portion 131. The elastic mechanism 140 pushes the first clamping arm along the motor axis to move closer to the first clamping arm through elastic force to clamp the motor between the first clamping arm 120 and the first clamping arm 110. When clamping, the output shaft at the front end of the motor is inserted into the first opening 111, and the limiting surface is fitted with the surface of the motor cover to achieve limiting.

[0036] The driving mechanism includes a cylinder 210 , a manual valve 220 and a connecting mechanism 230 . The manual valve 220 is used to control the operation of the cylinder. The piston rod in the cylinder 210 is connected to the connecting mechanism 230 .

[0037] The connecting mechanism is connected to the first clamping arm, and the structure of the connection is as follows: Figure 2As shown. The end of the first clamping arm 120 has a rod 121 arranged along the axial direction of the motor, and a limit end 122 is arranged on the rod. The connecting mechanism has an upwardly open movable groove 231, and the movable groove 231 also has a limit surface 233. The rod 121 and the limit end 122 are placed in the movable groove through the opening of the movable groove 231 and can move along the rod 121 in the movable groove to abut or leave the limit surface 233. Figure 2 The connecting mechanism is directed toward Figure 2 When the right side moves, the limit end 122 is elastically abutted against the limit surface 233. At the same time, due to the action of the stop portion 310 in the stop base, the second clamping arm 110 remains stationary, the first clamping arm moves away from the second clamping arm, and the clamp is in a state of loosening the clamp, and the clamp remains connected to the connecting mechanism. Figure 3 The connecting mechanism is directed toward Figure 3 When moving to the left, the limit end 122 stops moving and leaves the limit surface 233 after the first clamping arm contacts the motor. At this time, the first clamping arm and the second clamping arm clamp the motor through the elastic force of the elastic mechanism, and the clamp can be removed from the connecting mechanism.

[0038] When in use, the manual valve 220 is operated to control the cylinder to move to the right. At this time, due to the reverse elastic force of the elastic mechanism 140 connected to the first clamping arm, the limit end 122 on the first clamping arm abuts against the abutment surface 233 in the connecting mechanism 230, so that the movement of the cylinder can drive the first clamping arm 120 away from the first clamping arm 110. At this time, the clamp is in a loosened clamping state and the clamp remains connected to the connecting mechanism. Then, the motor is placed horizontally on the supporting part 131 of the clamp, with the front end of the motor with the output shaft facing the second clamping arm 110, and then the manual valve is operated to move the cylinder to the left. During the movement, the first clamping arm keeps approaching until the end of the motor is released. The motor is thrust by the first clamping arm 120 and fits with the first clamping arm. At this time, the first clamping arm no longer moves, and the connecting mechanism can continue to move, so that the limit end 122 on the first clamping arm leaves the abutment surface 233 of the connecting mechanism 230. At this time, the clamping force of the motor is provided by the elastic force of the elastic mechanism, and the clamp can be removed from the connecting mechanism. After taking out the clamp that clamps the motor, the motor is powered on to test its noise. During the test, the clamp can be held and the angle can be continuously changed, making the noise test easier.

[0039] The embodiments of the present invention are only used to illustrate the present invention 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 invention.
