[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example

[0022] Please refer to Figure 1-Figure 5 , a flip fixture for a new energy powertrain control box includes a main board 1, which is arranged in a cross shape, and side clamping parts are arranged at both ends along the width direction of the main board 1, and a vertical limiting part is arranged at the bottom of one end along the length direction of the main board 1. When the main board 1 is moved to the top of the control box 6 after horizontal lifting, one end of the side clamping part is used to limit the surface parts on both sides of the control box 6, and the bottom end of the vertical limiting part is limited at the top of one end of the control box 6. A positioning shaft 12 is rotatably connected to the middle of the top of the main board 1 through a rotating member. The positioning shaft 12 has a certain weight. When the positioning shaft 12 is flipped to a side close to the top of the main board 1 and close to the vertical limiting part, the positioning shaft 12 provides downward pressure on the main board 1 to force the bottom end of the positioning pin 7 to be tightly attached to the top of one end of the control box, so that the control box can be stably limited in the vertical direction through the vertical limiting part, preventing the control box 6 from shaking in the up and down directions when installing the control box 6, avoiding shaking when installing the control box 6, and improving the installation quality of the control box 6.

[0023] In an optional embodiment: the side clamping portion includes a limit support 8, a Z-shaped connecting plate 9, a spring pin 10, and a limit shaft 11. The limit support 8 is installed at the bottom of the main board 1 through the Z-shaped connecting plate 9, the spring pin 10 is arranged in the axial direction of the limit support 8, the limit shaft 11 is installed at the end of the spring pin 10 close to the main board 1, and the end of the limit shaft 11 close to the main board 1 is U-shaped, so the surface areas on both sides of the control box 6 can be limited by the limit shaft 11.

[0024] In an optional embodiment: a copper sleeve 15 is provided inside the limit support 8, and the spring pin 10 is inserted in the axial direction of the copper sleeve 15. The copper sleeve 15 facilitates the spring pin 10 to move in the axial direction of the limit support 8. A movable groove 81 is provided on the top of the limit support 8, and a cantilever pin 18 is inserted on the top of the spring pin 10. The top of the cantilever pin 18 passes through the movable groove 81 and is then installed with a limit buckle 16. The top of the limit support 8 has a convex portion 80 that matches the limit buckle 16. When the limit shaft 11 does not limit the two sides of the control box 6, the cantilever pin 18 is used to move the spring pin 10 in the axial direction of the limit support 8. 8 Pull the spring pin 10 in the direction away from the main board 1, and then insert the cantilever pin 18 downward into the spring pin 10, so that the limit buckle 16 moves downward, and one end of the limit buckle 16 is limited on one side of the protrusion 80, thereby locking the spring pin 10 on the limit support 8. When the limit shaft 11 limits the control box 6, pull the cantilever pin 18 upward again, so that the protrusion 80 no longer limits the limit buckle 16, and then the limit shaft 11 moves toward the control box 6 through the elastic force of the spring pin 10, so that one end of the limit shaft 11 limits the two sides of the control box 6.

[0025] In an optional embodiment: the rotating part includes a U-shaped connecting part 2 fixedly mounted on the top of the main board 1, one end of the positioning shaft 12 is rotatably mounted on the U-shaped connecting part 2 through a joint bearing 13 and a pin shaft 17, and the end of the positioning shaft 12 away from the U-shaped connecting part 2 is connected to a lifting ring 14, which facilitates the overall flipping of the heavy-weight positioning shaft 12 through the lifting ring 14.

[0026] In an optional embodiment: the vertical limiting portion includes a positioning pin 7, which is fixedly installed at the bottom end of the main board 1, and an L-shaped positioning block 19 is installed at the bottom of one end of the main board 1 away from the positioning pin 7. Specifically, the positioning pin 7 and the L-shaped positioning block 19 are adapted to the control box 6, and the rear end top of the control box 6 is limited by the L-shaped positioning block 19, and the positioning pin 7 is used to limit the front end top of the control box 6, so that the front and rear end tops of the control box 6 are stably limited up and down.

[0027] In an optional embodiment: it also includes a locking member for locking the positioning shaft 12, the locking member includes a locking seat 5 fixedly installed on the top of the mainboard 1 close to the positioning pin 7 and a dividing pin 22 installed on one side of the positioning shaft 12, the locking seat 5 is arranged in a convex shape, and a wire clamping groove 21 adapted to the locking seat 5 is opened on the positioning shaft 12, and a positioning hole 50 adapted to the dividing pin 22 is opened on the top of the locking seat 5. When the wire clamping groove 21 on the positioning shaft 12 is flipped and inserted into the locking seat 5, one end of the dividing pin 22 is inserted into the positioning hole 50 to lock the positioning shaft 12 to the locking seat 5. Then, the flipped positioning shaft 12 can be locked on the mainboard 1 through the locking member to avoid shaking of the positioning shaft 12 on the mainboard 1 when the control box 6 is installed.

[0028] In an optional embodiment: a handle 4 is provided on the top of the main board 1, and the handle 4 facilitates the movement of the entire clamp of the present application.

[0029] Specifically, before installing the control box 6, first, hoist the control box horizontally to the bottom of the main board 1, pull the cantilever pin 18 upward, so that the protrusion 80 no longer limits the limit buckle 16, and then use the elastic force of the spring pin 10 to move the limit shaft 11 in the direction of the control box 6, so that one end of the limit shaft 11 is close to the control box 6, and one end of the limit shaft 11 is used to limit the two sides of the control box 6, thereby stably limiting the two side surface parts of the control box 6, and then flip the positioning shaft 12 90 degrees, so that one side of the positioning shaft 12 is close to the main board 1, and then the flipped positioning shaft 12 can be locked on the main board 1 through the locking piece, so that the positioning shaft 12 provides downward pressure on the main board 1 to force the bottom end of the positioning pin 7 to be close to the front end top of the control box, so that the control box can be stably limited in the vertical direction through the vertical limiting part, preventing the control box 6 from shaking in the up and down directions when installing the control box 6, avoiding shaking when installing the control box 6, and improving the installation quality of the control box 6.

[0030] After the control box 6 is installed, the limit shaft 11 is reset to allow the spring pin 10 to be locked by the limit buckle 16, and then the fixture is removed, the flip positioning shaft 12 is reset, and the control box is waited for the next hoisting.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
