[0003] However, the adjustment function of existing motor housing machining fixtures has obvious limitations: most fixtures only have the ability to adjust in one direction, or can only achieve horizontal circumferential rotation to adapt to side machining, or can only be fixed in a vertical plane and cannot be adjusted, making it difficult to switch to the orientation suitable for machining. The direction needs to be switched by disassembly and reassembly, which is cumbersome and time-consuming, resulting in excessive machining auxiliary time and low efficiency. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-5As shown, this utility model provides a fixture for processing automotive motor housings, including an L-shaped base 1. A middle plate 2 is horizontally rotatably mounted on the upper vertical part of the L-shaped base 1, and a plug-in assembly 4 for fixing the position of the middle plate 2 is provided on the upper vertical part of the L-shaped base 1. A flip plate 3 is rotatably connected to the upper end of the middle plate 2, and a fixing limiting structure 5 for vertically fixing the flip plate 3 above the middle plate 2 is provided on the lower side of the flip plate 3. A top support limiting member is provided on the upper end of the middle plate 2 for fixing the flip plate 3 to a horizontal state. A shaft 11 is rotatably connected to the upper end of the flip plate 3, and a three-phase plate 12 is fixedly connected to the end of the shaft 11. Clamping plates 13 are provided on all three sides of the three-phase plate 12, and adjusting assemblies 6 for moving the clamping plates 13 are provided on all three sides of the three-phase plate 12. A turntable 14 for rotating the shaft 11 is provided on the other side of the flip plate 3, and a bolt plug-in member 7 for fixing the rotation position of the turntable 14 is provided on the upper end of the flip plate 3.

[0028] Reference Figure 2 As shown, a disc 8 is fixedly connected to the upper vertical part of the L-shaped base 1, and the middle plate 2 is rotatably connected to the axis of the disc 8. Top blocks 9 are fixedly connected to both sides of the upper vertical part of the L-shaped base 1, and the thickness of the top blocks 9 is adapted to the gap between the middle plate 2 and the upper part of the L-shaped base 1. The insertion assembly 4 includes a pin sleeve 401 fixedly connected to the side wall of the middle plate 2, and a pin 402 is inserted into the pin sleeve 401. Positioning holes 403 for insertion into the pin 402 are opened on both sides of the disc 8. A magnetic plate 404 is fixedly connected to the end of the pin 402. 4. The iron pin sleeve 401 is magnetically connected. By rotating the middle plate 2 180 degrees, the clamped motor housing can be positioned above the horizontal part of the L-shaped base 1, making the clamping and placement more stable. When it is necessary to process the circumferential surface of the motor housing, the middle plate 2 is rotated to drive the pin sleeve 401 to the other side of the disc 8. The orientation of the middle plate 2 and the flip plate 3 is adjusted by inserting the pin 402 into the pin sleeve 401 and the positioning hole 403 at the same time. At the same time, the magnetic plate 404 can prevent the pin 402 from falling off accidentally through magnetic force. The top block 9 can provide stable support for the middle plate 2.

[0029] As an optional implementation, the top support limiting member includes four triangular plates 10, and the four triangular plates 10 are distributed in pairs on both sides of the middle plate 2. When the flip plate 3 is flipped to a horizontal state, the upper side of the triangular plates 10 abuts against it. The triangular plates 10 can provide stable support when the flip plate 3 is placed horizontally, making the flip plate 3 more stable.

[0030] Reference Figure 3As shown, the fixed limiting structure 5 includes a through groove 501 that passes through the lower side of the flip plate 3. A threaded rod 502 is rotatably connected in the through groove 501. A U-shaped clamp 503 is provided in the through groove 501, and the closed end of the U-shaped clamp 503 has a threaded hole 504 that is threadedly connected to the threaded rod 502. The opening of the U-shaped clamp 503 faces the middle plate 2, and the inner thickness of the U-shaped clamp 503 is adapted to the middle plate 2. There is a clearance fit between the U-shaped clamp 503 and the through groove 501. The flip plate 3 is rotated upward to make it perpendicular to the middle plate 2. The threaded rod 502 is rotated to drive the U-shaped clamp 503 to move downward until the U-shaped clamp 503 is inserted above the middle plate 2, thus completing the fixation of the flip plate 3. The clearance fit between the U-shaped clamp 503 and the through groove 501 makes the U-shaped clamp 503 more stable when moving. At the same time, when the U-shaped clamp 503 is inserted into the upper end of the middle plate 2, the flip plate 3 will be restricted from rotating left and right, thus achieving the fixing effect.

[0031] Reference Figure 4 As shown, the adjustment assembly 6 includes movable slots 601 on three sides of the three-phase plate 12. Threaded rods 602 are rotatably connected to the movable slots 601, and square sleeves 603 are threaded onto the threaded rods 602. Clamping plates 13 are fixedly connected to the square sleeves 603. There is a clearance fit between the square sleeves 603 and the movable slots 601. Each of the three sides of the three-phase plate 12 is provided with a scale bar 604 that matches the length of the movable slots 601. When the motor housing is placed on the surface of the three-phase plate 12, the three threaded rods 602 are rotated respectively, causing the square sleeves 603 to move in the movable slots 601 until the clamping plates 13 contact and clamp the motor housing. The scale bars 604 can be used to check the movement position of the three clamping plates 13 to ensure the relative stability of the three clamping plates 13 when clamping the motor housing.

[0032] Reference Figure 5 As shown, the bolt connector 7 includes a threaded sleeve 701 fixedly connected to the upper end of the flip plate 3. The threaded sleeve 701 is threaded with a bolt 703. The turntable 14 has several fixing holes 702 for inserting the bolt 703. After the turntable 14 rotates to a suitable processing position, the bolt 703 is inserted into the fixing holes 702 and the threaded sleeve 701 and rotated to fix the position of the turntable 14, thus preventing the motor housing from deflecting and shaking during the processing.

[0033] The working principle of this utility model:

[0034] In use, rotate the flip plate 3 to place it horizontally, at which point it presses down on the triangular plate 10, while the three-phase plate 12 is positioned above. Then, place the motor housing on the three-phase plate 12 and rotate the three threaded rods 602 respectively, causing the square threaded sleeve 603 to move in the movable groove 601 until the clamping plate 13 contacts and clamps the motor housing. At this time, rotating the turntable 14 can drive the motor housing to rotate and process its end face. When it is necessary to process the circumferential surface of the motor housing, rotate the middle plate 2 to drive the pin sleeve 401 to the other side of the disc 8, and adjust the orientation of the middle plate 2 and the flip plate 3 by simultaneously inserting the pin 402 into the pin sleeve 401 and the positioning hole 403. Then, rotate the flip plate 3 upward to make it perpendicular to the middle plate 2, and rotate the threaded rod 502 to drive the U-shaped clamp 503 downward until the U-shaped clamp 503 is inserted above the middle plate 2, thus fixing the flip plate 3. At this time, the fixed motor housing is placed horizontally, and the circumferential surface can be processed.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
