Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a disc-type positioning fixture based on the motor end cover of a new energy vehicle. Background Technology

[0002] Motor end covers are an important component of motors, usually installed at both ends. They protect the internal components from dust, moisture, corrosion, and physical damage, thus extending the motor's service life. They also provide support and fixation for the rotor and bearings, enabling them to operate stably and maintaining a certain and uniform gap between the stator and rotor, thereby ensuring the normal operation of the motor.

[0003] Existing motor end caps require clamping and fixing during manufacturing. Traditional clamps typically clamp the motor end cap directly from the outside or support it from the inside, making it impossible to pre-position and fix it. This results in inconsistent precision during the manufacturing process. Regardless of whether the clamping is from the outside in or from the inside out, improper force control can lead to unstable clamping or damage to the motor end cap. Therefore, this invention proposes a disc-type positioning clamp for new energy vehicle motor end caps. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a disc-type positioning fixture for the end cover of a new energy vehicle motor. By setting a disc-type clamping component, it can stably press and fix the motor end cover placed on the worktable, ensuring the stability of the motor end cover during processing. At the same time, an auxiliary structure with a center hole for the motor end cover is provided on the top of the worktable, which can center the motor end cover of different sizes, improving the positioning and installation efficiency during the processing of the motor end cover.

[0013] Through the above technical solution, the movable plate is pressed against the slip ring at its bottom by the connecting rod, thereby pressing multiple springs A. The restoring elasticity of multiple springs A is used to ensure that the adjusted movable plate can be stably pressed against the bottom of the adjusting nut, and to achieve stable clamping and fixing of the motor end cover.

[0014] The present invention is further configured such that the slip ring and the positioning ring are respectively sleeved on the central column and are smoothly fitted to the outer wall.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figures 1-4 As shown, a disc-type positioning fixture based on the end cap of a new energy vehicle motor includes a worktable 1. The worktable 1 includes a central column 11. The inner wall of an adjusting nut 2 is threadedly connected to the outer wall of the central column 11. A base plate 12 is fixedly connected to the bottom of the central column 11. Multiple mounting slots 13 are evenly provided on the outer wall of the base plate 12. A top plate 14 is fixedly connected to the top of the central column 11. An auxiliary structure 5 is installed at the top center of the top of the top plate 14, which facilitates the positioning and fixing of the entire worktable 1 using the base plate 12 and the mounting slots 13. The top plate 14 facilitates the placement and fixing of the motor end cap. An adjusting nut 2 is threadedly connected to the middle of the worktable 1. A clamping assembly 3 is slidably connected to the middle of the worktable 1 and abuts against the bottom of the adjusting nut 2. The clamping assembly 3 includes a movable plate 31 sleeved on the outer wall of the central column 11. Multiple clamping rods 32 are evenly movably connected to the outer wall of the movable plate 31. Multiple clamping rods 32 are rotatably connected to multiple positioning pins 15 at the bottom of the top plate 14 near the top position. By rotating the adjusting nut 2, the movable plate 31 is pressed, causing the clamping rods 32 to rotate on the positioning pins 15, thereby pressing and fixing the motor end cover. Multiple movable grooves 311 are evenly opened on the outer wall of the movable plate 31. Positioning shafts 312 are fixedly connected inside the multiple movable grooves 311. The end faces of the multiple clamping rods 32 are movably connected to the positioning shafts 312 through their auxiliary grooves 321. A clamping block 322 is provided on the top of the clamping rod 32. When the movable plate 31 is pressed and adjusted, it can be pressed by the positioning shaft 312 at the end of the clamping rod 32 with the auxiliary groove 321, so that the clamping rod 32 can drive the clamping block 322 to adjust the angle, thereby pressing and fixing the motor end cover after placement.

[0029] like Figure 4As shown, the bottom of the clamping assembly 3 is bolted to an elastic assembly 4. The elastic assembly 4 includes multiple connecting rods 41 connected to the bottom of the movable plate 31. The bottom of the multiple connecting rods 41 is bolted to a slip ring 42. The slip ring 42 and the positioning ring 44 are respectively sleeved on the central column 11 and are smoothly fitted to the outer wall. This allows the elastic assembly 4 to slide on the central column 11 through the slip ring 42 and the positioning ring 44 when it is squeezed, ensuring stability during operation. Multiple springs A43 are evenly fixedly connected to the bottom of the slip ring 42 near the outer wall. The bottom of the multiple springs A43 is fixedly connected to the positioning ring 44, so that the movable plate 31 squeezes the slip ring 42 at its bottom through the connecting rods 41, thereby squeezing the multiple springs A43. The return elasticity of the multiple springs A43 is used to make the adjusted movable plate 31 stably press against the bottom of the adjusting nut 2, and to achieve stable clamping and fixing of the motor end cover.

[0030] like Figure 5 As shown, an auxiliary structure 5 is detachably installed at the top center of the workbench 1. The auxiliary structure 5 includes a positioning post 51. Multiple positioning grooves 52 are evenly opened on the outer wall of the positioning post 51. Adjusting plates 53 are rotatably connected to the inner walls of the multiple positioning grooves 52 near the top. Springs B54 are fixedly connected to the side walls of the multiple adjusting plates 53 near the bottom. The other end of the springs B54 is engaged with the inside of the positioning grooves 52, so that when the motor end cover is installed, it can be pre-positioned and fixed by the positioning post 51. During the continuous pressing process, the adjusting plate 53 is pressed. At the same time, under the action of the springs B54 inside the adjusting plate 53, the adjusting plate 53 presses and fixes the externally fitted motor end cover, thereby cooperating with the external clamping assembly 3 to fix the motor end cover.

[0031] In use, the motor end cover is first fitted onto the positioning post 51 through the central shaft hole. As it moves downward, it presses against the adjusting plate 53. Under the restoring elasticity of the compression spring B54, the adjusting plate 53 can position and fix the motor end cover. Then, the adjusting nut 2 is rotated to press against the bottom movable plate 31. The movable plate 31 is pressed against the end of the clamping rod 32 with the auxiliary groove 321 via the positioning shaft 312. This allows the clamping rod 32 to adjust the angle of the clamping block 322, thus pressing and fixing the edge of the placed motor end cover. The movable plate 31 is pressed against the slip ring 42 at its bottom via the connecting rod 41, which in turn presses against multiple springs A43. The restoring elasticity of the multiple springs A43 ensures that the adjusted movable plate 31 is stably pressed against the bottom of the adjusting nut 2, achieving stable clamping and fixing of the motor end cover.
