In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] Such as Figures 1-3As shown, in this embodiment, the impact test tooling is used to fix the pump or motor 100. The pump or motor 100 includes a transmission shaft. The impact test tooling includes a plurality of shaft locking members 1, a tooling plate 2, a first connecting member 3, a support member 4, and a second connecting member 5. Among them, the tooling plate 2 is provided with kidney-shaped mounting holes 21. A plurality of shaft locking members 1 are arranged on the tooling plate 2 and are used to lock the transmission shaft. The shaft locking members 1 are provided with through holes 11. The first connecting member 3 is used to selectively fix one of the plurality of shaft locking members 1 to the tooling plate 2. The first connecting member 3 can pass through the through hole 11 of any shaft locking member 1 and be fixed at any position of the kidney-shaped mounting hole 21. The support member 4 is used to support the pump or motor 100 on the tooling plate 2. The support member 4 is provided with a communication hole. The second connecting member 5 passes through the connection hole of the pump or motor 100 and the communication hole and is connected to the tooling plate 2. Specifically, the first connecting member 3 and the second connecting member 5 are fixing bolts. The support member 4 and the shaft locking members 1 are both arranged between the pump or motor 100 and the tooling plate 2, and the support member 4 is located beside the shaft locking members 1. Before performing an impact test on the pump or motor 100, the transmission shaft of the pump or motor 100 needs to be locked. The pump or motor 100 is provided with a connection hole. First, the shaft locking member 1 matching the transmission shaft is installed on the tooling plate 2 through the first connecting member 3. Then, the transmission shaft is inserted and clamped into the locking hole of the shaft locking member 1 so that the transmission shaft is relatively locked. At the same time, the pump or motor 100 is installed on the tooling plate 2 through the support member 4 and the second connecting member 5, which is convenient for performing an impact test on the pump or motor 100. When different models and sizes of pumps or motors 100 need to be installed on this tooling for impact testing, the shaft locking members 1 matching the corresponding transmission shaft sizes are replaced. That is, the number of teeth and the diameter of the transmission shafts corresponding to different models of pumps or motors 100 are different, so the diameter of the locking holes and the tooth grooves of the shaft locking members 1 need to correspond and be consistent, and the overall thickness and outer diameter between different shaft locking members 1 are also different. Therefore, the first connecting member 3 can pass through the through hole 11 of any shaft locking member 1 and be fixedly connected to any position of the kidney-shaped mounting hole 21 of the tooling plate 2 to adapt to the different radial positions of the corresponding through holes 11 of different shaft locking members 1, enabling the same tooling plate 2 to be adapted to a plurality of shaft locking members 1, solving the problem that one type of pump or motor 100 can only use one type of impact test tooling, thereby reducing the number of impact test toolings and lowering the cost. Finally, in order to ensure that the connection end at the top of the pump or motor 100 is at the same height as the external device, that is, the axial dimensions between different models of pumps or motors 100 are different, the axis of the pump or motor 100 coincides with the central axis direction of the shaft locking members 1. The support member 4 is detachably connected to the tooling plate 2 through the second connecting member 5, and different lengths of support members 4 can be replaced for adaptation. At the same time, since the thicknesses corresponding to different models of shaft locking members 1 are different, the height is adjusted by replacing the support member 4 so that different shaft locking members 1 can be arranged between the pump or motor 100 and the tooling plate 2, with strong versatility.

[0040] Further, continue to refer to Figures 1-3, the impact test tooling further includes a first washer 6. The first washer 6 is located between the support member 4 and the tooling plate 2. The second connecting member 5 sequentially passes through the connection hole, the communication hole of the pump or motor 100, and the first washer 6 and is connected to the tooling plate 2. There are multiple first washers 6, and the multiple first washers 6 are stacked. Specifically, in order to ensure that the connection end at the top of the pump or motor 100 is at the same height as the external device, in addition to replacing the support member 4 with different lengths, the number of first washers 6 can also be increased or decreased to raise or lower the pump or motor 100 relative to the tooling plate 2, so as to adjust the axial dimension of the pump or motor 100 installed on the support member 4.

[0041] Further, continue to refer to Figures 1-3 , the impact test tooling further includes a second washer. The second washer is located between the support member 4 and the pump or motor 100. The second connecting member 5 sequentially passes through the connection hole of the pump or motor 100, the second washer, and the communication hole and is connected to the tooling plate 2. There are multiple second washers, and the multiple second washers are stacked. The principle of adjusting the number of the first washers 6 to ensure that the connection end at the top of the pump or motor 100 is at the same height as the external device is the same here, so it will not be elaborated too much.

[0042] Further, continue to refer to Figures 1-3 , there are multiple kidney-shaped mounting holes 21. The multiple kidney-shaped mounting holes 21 are radially and spaced apart along the circumferential direction of the locking shaft member 1. There are multiple first connecting members 3, and the multiple first connecting members 3 are arranged in one-to-one correspondence with the multiple kidney-shaped mounting holes 21. Specifically, the locking shaft member 1 is installed on the tooling plate 2 through the multiple first connecting members 3 respectively passing through the corresponding through holes 11 and the kidney-shaped mounting holes 21 of the tooling plate 2. The kidney-shaped mounting holes 21 are in a kidney-shaped structure. The positions of the through holes 11 corresponding to different locking shaft members 1 are different in the radial direction. The center line direction of the kidney-shaped mounting holes 21 coincides with the radial direction of the locking shaft member 1. Through the connection and cooperation of the first connecting member 3 and the kidney-shaped mounting holes 21 of the kidney-shaped structure, locking shaft members 1 of different sizes can be installed on the same tooling plate 2.

[0043] Further, continue to refer to Figures 1-3 , the tooling plate 2 is further provided with a clearance hole 25. The clearance hole 25 is located at the central position surrounded by the multiple kidney-shaped mounting holes 21 along the circumferential direction. Specifically, before performing an impact test on the pump or motor 100, the transmission shaft of the pump or motor 100 needs to be locked. The locking shaft member 1 is installed on the tooling plate 2 through the first connecting member 3, and then the transmission shaft is inserted and clamped into the locking hole of the locking shaft member 1 to relatively lock the transmission shaft. Since the lengths of the transmission shafts of different pumps or motors 100 are different, when the transmission shaft is clamped into the locking hole of the locking shaft member 1, the transmission shaft extending outwards relative to the locking shaft member 1 can pass through the clearance hole 25 without affecting the normal use of the impact test tooling.

[0044] Further, continue to refer toFigures 1-3 The tooling plate 2 is further provided with a plurality of first positioning holes 22, and the second connecting member 5 passes through the connecting holes and the communication holes of the pump or the motor 100 and is connected to the first positioning holes 22. The plurality of first positioning holes 22 are arranged in a matrix, and there are a plurality of second connecting members 5. The plurality of second connecting members 5 are arranged in one-to-one correspondence with the plurality of first positioning holes 22. The pump or the motor 100 is installed and fixed on the tooling plate 2 through the plurality of second connecting members 5, the corresponding first positioning holes 22 and the support member 4.

[0045] Further, with continued reference to Figures 1-3 The tooling plate 2 is further provided with second positioning holes 23 and adjustment holes 24. The adjustment holes 24 are in an arc-shaped structure. There are a plurality of second connecting members 5. The plurality of second connecting members 5 pass through the connecting holes and the communication holes of the corresponding pump or motor 100 and are respectively connected to the second positioning holes 23 and the adjustment holes 24. Specifically, there are two second positioning holes 23 and two adjustment holes 24. Along the circumferential direction of the locking shaft member 1, the two second positioning holes 23 and the two adjustment holes 24 are opposite and spaced apart. Since the distances between the plurality of connecting holes corresponding to pumps or motors 100 of different models are different, the positions of the two diagonally arranged second positioning holes 23 are fixed, and the other two diagonally arranged waist-shaped adjustment holes 24 can install and fix pumps or motors 100 of different models through the second connecting members 5, with strong versatility. Optionally, the second positioning holes 23 are in an arc-shaped structure or a strip-shaped structure, and cooperate with the arc-shaped adjustment holes 24 to be able to install pumps or motors 100 of different sizes.

[0046] Further, with continued reference to Figures 1-3 The locking shaft member 1 includes a locking portion 12 and a connecting portion 13. The connecting portion 13 is in an annular structure. Along the circumferential direction of the connecting portion 13, the inner ring of the connecting portion 13 is connected to the outer peripheral surface of the locking portion 12. The connecting portion 13 is provided with a plurality of through holes 11, and there are a plurality of first connecting members 3. The plurality of first connecting members 3 are arranged in one-to-one correspondence with the plurality of through holes 11. Specifically, the number of teeth of the transmission shafts corresponding to pumps or motors 100 of different models is different, and thus it is necessary to ensure that the number of tooth grooves in the lock holes of the corresponding locking portion 12 is the same as that. The plurality of through holes 11 are arranged at intervals along the circumferential direction of the annular connecting portion 13 and are fixed to the tooling plate 2 through the first connecting members 3.

For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
