[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0044] The structure and function of this utility model are as follows:

[0045] like Figures 1-10As shown, a performance testing device for power equipment includes a test bench mechanism 1. A drive motor 3 is mounted on the top of the test bench mechanism 1 via a lifting seat mechanism 2. A test seat mechanism 6 for supporting a test piece 8 is also mounted on the top of the test bench mechanism 1. Driven by the lifting seat mechanism 2, the drive motor 3 moves vertically upwards or downwards, ensuring that the output shaft of the drive motor 3 is at the same height as the output shaft of the test piece 8. A coupling 7 connects the output shaft of the drive motor 3 to the output shaft of the test piece 8. The drive motor 3 drives the output shaft of the test piece 8 to rotate via the coupling 7, thereby performing performance testing on the test piece 8. By setting up the lifting seat mechanism 2 and the test seat mechanism 6, the output shaft of the drive motor 3 can be ensured to be at the same height as the output shaft of test pieces 8 of different specifications, thereby improving the compatibility of the testing device and effectively increasing production and testing efficiency. Simultaneously, it can reduce production costs and improve testing flexibility.

[0046] like Figures 2-3 As shown, the structure of the test bench mechanism 1 includes a frame 101, with a platform 102 mounted on the top of the frame 101 via several shock absorbers 103. The test bench mechanism 1 supports and mounts the lifting seat mechanism 2 and the test seat mechanism 6, providing a stable, accurate, and reliable testing environment. By setting the frame 101 as the main support structure of the test bench mechanism 1, the overall stability and load-bearing capacity of the testing device can be guaranteed. The platform 102 provides an mounting surface for the lifting seat mechanism 2 and the test seat mechanism 6, thereby improving the accuracy and reliability of the test results. The shock absorbers 103 absorb and disperse vibration energy, thus maintaining the stability of the platform 102 and improving the precision and accuracy of the test.

[0047] In addition, a cover plate 9 is installed on the outside of the frame 101 to protect the components installed inside the frame 101. An electrical control cabinet 4 for controlling the operation of the drive motor 3 is arranged on one side of the frame 101. An energy recovery base plate 104 is installed at the bottom of the frame 101, and an energy recovery device (not shown in the figure) is installed on the energy recovery base plate 104. By setting the energy recovery device, the vibration mechanical energy generated during the testing of the test piece 8 can be recovered, thereby improving the energy utilization efficiency of the testing device.

[0048] like Figures 5-6As shown, the structure of the lifting seat mechanism 2 is: including a driving cylinder 201 fixed on the test bench mechanism 1, and a lifting plate 202 for installing the driving motor 3; the output end of the driving cylinder 201 is connected with the lifting plate 202, and the driving cylinder 201 is extended or retracted, so that the driving motor 3 is driven to move up or down in a straight line along the vertical direction through the lifting plate 202. By arranging the lifting seat mechanism 2, the driving motor 3 can be driven to move up and down along the vertical direction, so that the arrangement height of the output shaft of the driving motor 3 can be adjusted to match the arrangement height of the output shaft of the measured part 8.

[0049] A plurality of guide assemblies are arranged between the lifting plate 202 and the test bench mechanism 1, and the guide assemblies are used for guiding the lifting plate 202 to move up and down along the vertical direction; by arranging the guide assemblies, the movement stability of the lifting plate 202 can be improved. As shown, Figure 6 In the utility model, four groups of guide assemblies are arranged, and a single guide assembly comprises a guide rod seat 203 fixed on the top of the test bench mechanism 1 and a guide rod 205 fixed on the bottom of the lifting plate 202, and the guide rod 205 is slidably arranged with the guide rod seat 203 through a copper sleeve 204. A central hole is formed in the middle of a single guide rod seat 203, and the guide rod 205 is arranged in the central hole in a matched mode, and the copper sleeve 204 is arranged between the outer circumferential surface of the guide rod 205 and the inner side wall surface of the central hole, and the copper sleeve 204 is made of graphite brass sleeve, which can reduce the friction coefficient of the contact surface and ensure the smooth sliding of the guide rod 205 along the guide rod seat 203.

[0050] When the driving cylinder 201 is extended, an equal-height pad 5 is arranged between a single guide assembly and the lifting plate 202, and the gap between the top end surface of the guide rod seat 203 and the bottom end surface of the lifting plate 202 is filled through the equal-height pad 5, so that the lifting plate 202 can stably support the driving motor 3. In the utility model, three groups of equal-height pad assemblies are arranged, and a single equal-height pad assembly comprises four equal-height pads 5 with equal thickness, and by arranging the equal-height pad 5, the lifting plate 202 can be prevented from shaking after the driving cylinder 201 drives the lifting plate 202 to move to the position, so that the working stability of the driving motor 3 in the subsequent test process can be improved.

[0051] The lifting plate 202 is fixed with a mounting seat 206, as shown, Figures 4-5 , Figure 7 As shown, the mounting seat 206 can be fixed on the top of the lifting plate 202, or, as shown, Figure 6 The mounting seat 206 can be fixed on the bottom of the lifting plate 202, and a pull wire sensor 207 is arranged between the mounting seat 206 and the shell of the driving motor 3 in a matched mode. By arranging the pull wire sensor 207, the displacement of the driving motor 3 during the test process can be monitored, so that the displacement and offset problems of the driving motor 3 during the test process can be fed back in time, so as to ensure the accuracy of the test result.

[0052] AsFigures 4-6 As shown, one end of the pull-wire sensor 207 is fitted with a first spherical bearing 208, which is mounted to the housing of the drive motor 3 via a first connecting bolt 209. The other end of the pull-wire sensor 207 is hinged to the mounting base 206 via a hinge shaft 210. By setting the first spherical bearing 208 and the hinge shaft 210, displacement compensation can be performed to ensure that the relative position between the pull-wire sensor 207 and the housing of the drive motor 3 and the mounting base 206 remains unchanged, thereby accurately monitoring the amount of displacement.

[0053] like Figure 5 As shown, during the installation of the draw wire sensor 207, it is calibrated by the calibration weight assembly 211 to ensure the working accuracy of the draw wire sensor 207.

[0054] like Figures 7-8 As shown, this utility model provides another installation method for the pull-wire sensor 207. Both ends of the pull-wire sensor 207 are fitted with second joint bearings 212. One second joint bearing 212 is installed in conjunction with the housing of the drive motor 3 via a second connecting bolt 213, and the other second joint bearing 212 is installed in conjunction with the mounting base 206 via another second connecting bolt 213. By setting the second joint bearings 212, displacement compensation is performed on the pull-wire sensor 207.

[0055] like Figures 9-10 As shown, the structure of the test seat mechanism 6 includes a first pad 601 and at least two pressure plates 603. The end face of the first pad 601 has a symmetrically arranged group of positioning holes. Each pressure plate 603 has an adjustment hole 605 on its end face, with each adjustment hole 605 corresponding to one of the positioning hole groups. Adjusting bolts 607 are installed in both the individual adjustment hole 605 and the corresponding positioning hole group, thereby fixing the corresponding pressure plate 603 onto the first pad 601, and thus causing both pressure plates 603 to simultaneously press against the workpiece 8 to be tested. Each group of positioning holes includes several positioning holes 606. Each positioning hole 606 can be an oval hole. By setting the positioning hole 606, it is used to cooperate with the adjustment hole 605 to position the pressure plate 603.

[0056] In this invention, by setting two pressure plates 603, the two side walls of the test piece 8 can be pressed tightly at the same time, thereby limiting and fixing the test piece 8 and preventing it from shifting during the test.

[0057] In addition, several shims 604 are arranged at the bottom of the first pad 601, which are used to elevate the first pad 601.

[0058] The top of the first base plate 601 is matched with the installation of the second base plate 602, and the second base plate 602 is pressed on the first base plate 601 through two pressing plates 603. Two groups of arc-shaped slot groups are symmetrically arranged on the end face of the second base plate 602, and each group of arc-shaped slot groups comprises a plurality of arc-shaped slots 608. In the utility model, the arc-shaped slots 608 are arranged in one-to-one correspondence with the positioning holes 606, the installation position of the second base plate 602 is accurately positioned by aligning the arc-shaped slots 608 with the corresponding positioning holes 606, and the arrangement height of the to-be-tested part 8 is matched with the arrangement height of the driving motor 3 by further increasing the to-be-tested part 8 through the second base plate 602.

[0059] In the utility model, the to-be-tested part 8 is a diesel engine, a gasoline engine or a rotating motor.

[0060] The working process of the utility model is as follows:

[0061] Firstly, the to-be-tested part 8 is placed on the second base plate 602, the driving cylinder 201 extends a set stroke, so that the driving motor 3 is driven to ascend to a specified position along the vertical direction through the lifting plate 202, and then the output shaft of the driving motor 3 is level with the output shaft of the to-be-tested part 8.

[0062] Subsequently, an equal-height pad 5 is inserted between each guide rod seat 203 and the lifting plate 202;

[0063] Then, the driving cylinder 201 is retracted, so that the lifting plate 202 is tensioned and tightly attached to the equal-height pad 5;

[0064] Then, the output shaft of the driving motor 3 and the output shaft of the to-be-tested part 8 are connected through the shaft coupling 7, and then the two adjusting bolts 607 are tightened, so that the two pressing plates 603 simultaneously tightly press the to-be-tested part 8, thereby limiting and fixing the to-be-tested part 8;

[0065] Finally, the driving motor 3 is started to drive the output shaft of the to-be-tested part 8 to rotate, so that the torque and the rotating speed of the to-be-tested part 8 are tested in the rotating process of the output shaft of the to-be-tested part 8, and the performance of the to-be-tested part 8 is tested.
