[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 6As shown, the present invention is a new energy drive axle assembly torque detection device, comprising a workbench 1, a support plate 2, a rotating shaft 21 and a placement bin 19; and also comprising a fixed pushing unit arranged on the workbench 1;

[0044] The support plate 2 is fixedly arranged at one end of the top of the workbench 1;

[0045] One end of the rotating shaft 21 is rotatably disposed on the supporting plate 2;

[0046] The placement bin 19 is fixedly disposed at the other end of the rotating shaft 21;

[0047] The fixed pushing unit is arranged on the workbench 1, and comprises a driving component, a fixing component and a pushing component; the driving component is used to drive the fixing component to move; the driving component is used to drive the pushing component to move;

[0048] The drive axle assembly is placed on the pushing component, and then the driving component is driven to move the pushing component toward the inside of the workbench 1. The driving component drives the pushing component and also moves the fixing component downward to fix the drive axle assembly. Then, one end of the drive axle assembly is installed in the placement bin 19. After installation, the drive component drives the fixing component to fix the drive axle assembly firmly.

[0049] By placing the drive axle assembly on the pushing component, starting the driving component to move the pushing component, and making the pushing component drive the drive axle assembly to move into the workbench 1, when it moves to a certain position, insert one end of the drive axle assembly into the placement bin 19, and use the rotating shaft 21 to rotate the placement bin 19 to detect the torque of the drive axle assembly. This setting is to allow the drive axle assembly to be placed better and save manual transport back and forth to align it into the placement bin 19;

[0050] When the pushing component moves the drive axle assembly toward the inside of the workbench 1, the fixing component will also move driven by the driving component to firmly lock the drive axle assembly on the top of the workbench 1. This arrangement is to prevent the drive axle assembly from sliding and breaking free during rotation when the rotating shaft 21 drives the placement bin 19 to rotate to detect the drive axle assembly, causing the drive axle assembly to detach from the workbench 1, causing damage to the drive axle assembly, and also easily causing injuries to the staff who are detecting the torque nearby.

[0051] See also Figure 1 , Figure 2 and Figure 5 As shown, the driving assembly includes a driving motor 10, a support frame 9, a driving rod 11 and a moving block 12;

[0052] The fixing assembly includes a support rod 8, a placement block 5 and a fixing block 7;

[0053] The support frame 9 is fixedly arranged on one side of the workbench 1; the drive motor 10 is fixedly arranged on the top of the support frame 9; the drive rod 11 is rotatably arranged in the support frame 9, and the drive rod 11 is connected to the drive motor 10; the moving block 12 is rotatably arranged on the drive rod 11;

[0054] The support rods 8 are provided with two and are symmetrically fixed on the moving block 12; the fixed block 7 is fixedly provided at one end of the support rod 8 away from the moving block 12; the placement blocks 5 are provided with two and are symmetrically fixed on the top of the workbench 1;

[0055] The driving motor 10 drives the driving rod 11 on the supporting frame 9 to rotate. When the driving rod 11 rotates, the moving block 12 moves up and down. The moving moving block 12 drives the supporting rod 8 and the fixed block 7 to move up and down. When the fixed block 7 moves downward, it cooperates with the placement block 5 on the workbench 1 to firmly fix the drive axle assembly, so that the drive axle assembly will not slide or break free during torque detection.

[0056] See also Figure 2 , Figure 3 and Figure 4 As shown, the driving assembly further includes a rotating gear 27, a moving platform 17, a U-shaped groove 18, a supporting block 25 and a toothed plate 26;

[0057] The pushing assembly includes a limiting column 15, a sliding block 16, a fixing plate 14 and a supporting plate 13;

[0058] The rotating gear 27 is fixedly arranged at the bottom of the driving rod 11; the U-shaped groove 18 is fixedly arranged at the bottom of the workbench 1; the support block 25 is slidably arranged in the U-shaped groove 18; the moving platform 17 is fixedly connected to the support block 25; the tooth plate 26 is fixedly arranged at the bottom of the moving platform 17;

[0059] The limiting column 15 is fixedly arranged on the top of the moving platform 17; the sliding block 16 is slidably arranged on the limiting column 15; the fixing plate 14 is fixedly arranged on the top of the sliding block 16; the supporting plate 13 is fixedly arranged on the top of the fixing plate 14;

[0060] The driving rod 11 is rotated to drive the rotating gear 27 to rotate. Since the rotating gear 27 is in meshing state with the tooth plate 26, the rotating gear 27 will cause the tooth plate 26 to move forward or backward. The movement of the tooth plate 26 will drive the support block 25, the limiting column 15, the sliding block 16, the fixed plate 14 and the pallet 13 to move. In this way, the pallet 13 will send the drive axle assembly out of the workbench 1 or move it into the workbench 1, so that the drive axle assembly can be stuck in the placement bin 19, which reduces the handling work of the staff and avoids the problem of collision of the drive axle assembly caused by alignment and handling.

[0061] See also Figure 1 , Figure 3 and Figure 4 As shown, the pushing assembly further includes a sliding slot 23 and a sliding column 24;

[0062] The sliding groove 23 is provided in the workbench 1; the sliding column 24 is fixedly arranged on the sliding block 16; the sliding column 24 slides in the sliding groove 23;

[0063] By moving the movable table 17 and the limiting column 15 on the movable table 17, the sliding block 16 is pushed to move, which makes the sliding column 24 on the sliding block 16 slide in the sliding groove 23 on the workbench 1. Because the sliding groove 23 is set to a track shape from low to high, the sliding column 24 slides in the sliding groove 23 to make the sliding block 16 rise or fall on the limiting column 15. This setting is to avoid that when the drive axle assembly performs torque detection, the support plate 13 will hinder the rotation of the drive axle assembly, affecting its detection results and causing accidents due to the slippage of the drive axle assembly caused by the lifting.

[0064] See also Figure 2 , Figure 5 and Figure 6 As shown, a rotating motor 3 is fixedly connected to the support plate 2; the rotating motor 3 is connected to the rotating shaft 21; a fixed screw rod 4 is rotatably connected to the placement bin 19; two fixed screw rods 4 are provided and symmetrically arranged on the placement bin 19; a clamping block 20 is fixedly connected to one end of the fixed screw rod 4 located in the placement bin 19; a through hole 22 is opened on one side of the workbench 1 located on the support plate 2;

[0065] The rotating shaft 21 is driven to rotate by rotating the motor 3, so that the rotating shaft 21 drives the placement bin 19 to rotate, and the staff rotates the fixed screw 4 to move the fixed screw 4 into the placement bin 19, and the clamping block 20 at one end of the fixed screw 4 fixes the drive axle assembly, so that the placement bin 19 can better drive the drive axle assembly to rotate for torque detection. The through hole 22 is opened on the workbench 1 to prevent the extended fixed screw 4 from contacting and colliding with the workbench 1.

[0066] See also Figure 1 , Figure 2 and Figure 5 As shown, the top of the placing block 5 is fixedly connected to a limiting rod 6; the fixing block 7 is slidably arranged on the limiting rod 6;

[0067] By sliding the fixing block 7 on the limiting rod 6, the fixing block 7 can only slide up and down in one direction, thereby ensuring that the drive axle assembly can be fixed and limited.

[0068] See also Figures 1 to 6 As shown, two U-shaped grooves 18 are provided and symmetrically arranged at the bottom of the workbench 1; two support blocks 25 are provided and symmetrically arranged on both sides of the moving platform 17;

[0069] The two U-shaped grooves 18 and the support block 25 are provided so that the support block 25 can be symmetrically placed in the U-shaped groove 18 so that the moving platform 17 can remain stable and will not deflect or fall.

[0070] See also Figures 1 to 6 As shown, a new energy drive axle assembly torque detection method, the detection method comprises the following steps: S1: placing the drive axle assembly on the pallet 13, and then driving the motor 10 to drive the moving platform 17 to move into the workbench 1; S2: After the support plate 13 brings the drive axle assembly to the designated position, one end of the drive axle assembly is clamped into the placement bin 19, and the fixing screw 4 is rotated to fix one end of the drive axle assembly. At this time, the fixing block 7 also moves downward to clamp the drive axle assembly between the placement block 5 and the fixing block 7; S3: By rotating the rotating motor 3, the placement bin 19 is rotated to drive the drive axle assembly to rotate accordingly, thereby performing torque detection of the drive axle assembly.

[0074] The working principle of the present invention is as follows: by placing the drive axle assembly on the pushing assembly, starting the drive assembly to move the pushing assembly, and making the pushing assembly drive the drive axle assembly to move into the workbench 1, and when it moves to a certain position, inserting one end of the drive axle assembly into the placement bin 19, and using the rotating shaft 21 to rotate the placement bin 19 to detect the torque of the drive axle assembly. This arrangement is to allow the drive axle assembly to be placed better and save the manual back and forth movement to align it into the placement bin 19;

[0075] When the pushing component moves the drive axle assembly toward the inside of the workbench 1, the fixing component will also move driven by the driving component to firmly lock the drive axle assembly on the top of the workbench 1. This arrangement is to prevent the drive axle assembly from sliding and breaking free during rotation when the rotating shaft 21 drives the placement bin 19 to rotate to detect the drive axle assembly, causing the drive axle assembly to detach from the workbench 1, causing damage to the drive axle assembly, and also easily causing injuries to the staff who are detecting the torque nearby.

[0076] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
