[0026] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present utility model:
[0027] A test tooling for a motor bench of a new energy vehicle, including a workbench 1. On both sides of the center of the top of the workbench 1, there are fixedly connected guiding frames 2. The top of the guiding frame 2 is provided with sliding grooves 3. The inner wall of the sliding groove 3 is movably connected with a moving block 4. The top of the moving block 4 is fixedly connected with a connecting plate 5; on both sides of the top of the connecting plate 5, there are fixedly connected supporting plates 6. The inner wall of the supporting plate 6 is threadedly connected with an adjusting bolt 7. One end of the adjusting bolt 7 is rotatably connected with a clamping plate 8. The inner wall of the clamping plate 8 is fixedly connected with an anti-slip pad 9. The inner wall of the anti-slip pad 9 is fixedly connected with a test motor 10; through the settings of the workbench 1, the guiding frame 2, the sliding groove 3, the moving block 4 and the connecting plate 5, when in use, after the staff fixes the position of the test motor 10, only need to move the moving block 4 in the sliding groove 3 of the guiding frame 2, and let the moving block 4 drive the connecting plate 5 to move towards the fixing plate 11. At this time, the connecting plate 5 will drive the test motor 10 above to approach the dynamometer 12. The staff can extend the extension rod 22 on the measuring rod 21 and compare the height of the test motor 10 with the height of the dynamometer 12 to make the heights of the docking ports of the test motor 10 and the dynamometer 12 consistent. There is no need for the staff to carry out cumbersome docking work, reducing the workload of the staff. Through the settings of the connecting plate 5, the supporting plate 6, the adjusting bolt 7, the clamping plate 8, the anti-slip pad 9 and the test motor 10, when in use, the staff places the test motor 10 to be tested between the clamping plates 8. The staff rotates the adjusting bolt 7 according to the scale on the connecting plate 5, making the adjusting bolt 7 drive the clamping plate 8 to move inwards while ensuring that the moving lengths of the adjusting bolts 7 on both sides are the same, ensuring that the test motor 10 is in the middle position of the connecting plate 5 and can be perfectly docked with the dynamometer 12. The staff needs to adjust the height of the supporting plate 6 in the base cylinder 19 according to the height measured by the measuring rod 21 and fix it with the positioning bolt 20. There is an anti-slip pad 9 on the inner wall of the clamping plate 8. When the test motor 10 and the dynamometer 12 are being tested, it can not only prevent the test motor 10 from falling off, but also prevent the test motor 10 from being damaged by collision due to shaking during the test.
[0028] In this embodiment, preferably, one end of the top of the guiding frame 2 is fixedly connected with a fixing plate 11. The center of the top of the fixing plate 11 is fixedly connected with a dynamometer 12; through the settings of the guiding frame 2, the fixing plate 11 and the dynamometer 12, when in use, there is a dynamometer 12 on the fixing plate 11 for carrying out detection work with the test motor 10.
[0029] In this embodiment, preferably, the side of the dynamometer 12 is fixedly connected with a fixing frame 13. The bottom of the fixing frame 13 is fixedly connected to the top of the fixing plate 11 near both sides of the dynamometer 12; through the settings of the dynamometer 12, the fixing frame 13 and the fixing plate 11, when in use, the fixing frame 13 fixes the dynamometer 12 on the fixing plate 11.
[0030] In this embodiment, preferably, a clamping block 14 is fixedly connected to the top edge of the connecting plate 5, and a positioning plate 15 is fixedly connected to one end of the clamping block 14; through the settings of the connecting plate 5, the clamping block 14 and the positioning plate 15, during use, after the connecting plate 5 contacts the fixing plate 11, the staff fixes the clamping block 14 and the positioning plate 15 to prevent them from falling off and separating during the subsequent testing of the motor 10 and the dynamometer 12.
[0031] In this embodiment, preferably, a support block 16 is fixedly connected to the bottom of the workbench 1, and a soft pad 17 is fixedly connected to the bottom of the support block 16; through the settings of the workbench 1, the support block 16 and the anti-slip pad 9, during use, the support block 16 and the soft pad 17 provide stability for the device.
[0032] In this embodiment, preferably, a plug rod 18 is fixedly connected to the top of the positioning plate 15, and one end of the plug rod 18 is fixedly connected to the inner wall of the clamping block 14; through the settings of the positioning plate 15, the plug rod 18 and the clamping block 14, during use, the staff uses the plug rod 18 to fix the positioning plate 15 and the clamping block 14.
[0033] In this embodiment, preferably, a measuring rod 21 is fixedly connected to the side of the fixing plate 11 close to the fixing frame 13, and an extension rod 22 is movably connected to the bottom of the front surface of the measuring rod 21; through the settings of the fixing plate 11, the measuring rod 21 and the extension rod 22, during use, the staff can lengthen the extension rod 22 until it reaches the connecting plate 5 to correct the heights of the tested motor 10 and the dynamometer 12 and ensure the accurate docking of their interfaces.
[0034] When the test tooling of a new energy vehicle motor bench in this embodiment is in use, the staff places the test motor 10 to be tested between the clamping plates 8. The staff rotates the adjusting bolt 7 according to the scale on the connecting plate 5, so that the adjusting bolt 7 drives the clamping plates 8 to move closer inward while ensuring that the moving lengths of the adjusting bolts 7 on both sides are the same, ensuring that the test motor 10 is in the middle position of the connecting plate 5 and can be perfectly docked with the dynamometer 12. The staff needs to adjust the height of the support plate 6 in the base cylinder 19 according to the height measured by the measuring rod 21 and fix it with the positioning bolt 20. The inner wall of the clamping plate 8 is provided with an anti-slip pad 9. When the test motor 10 and the dynamometer 12 are being tested, it can not only prevent the test motor 10 from falling off, but also prevent the test motor 10 from being damaged by collision due to shaking during the test. After the staff fixes the position of the test motor 10, they only need to move the moving block 4 in the sliding groove 3 of the guiding frame 2, so that the moving block 4 drives the connecting plate 5 to move towards the fixed plate 11. At this time, the connecting plate 5 will drive the test motor 10 above towards the dynamometer 12. The staff can extend the extension rod 22 on the measuring rod 21 to compare the height of the test motor 10 with the height of the dynamometer 12, so that the heights of the docking ports of the test motor 10 and the dynamometer 12 are the same, eliminating the need for the staff to perform cumbersome docking work and reducing the workload of the staff.
