[0016] Please see Figure 1-2 This utility model provides a technical solution: a jig for machining a turbocharger housing that facilitates angle adjustment, comprising a base plate 1, a pair of upright plates 2 on the base plate 1, a pair of limiting rods 5 fixedly disposed between the pair of upright plates 2 and a threaded rod 4 rotatably disposed therebetween, a first motor 3 disposed on the base plate 1, the output shaft of the first motor 3 being connected to the threaded rod 4, a threaded sleeve 8 being threadedly connected to the threaded rod 4, a pair of sliders 7 being horizontally slidably connected to the pair of limiting rods 5, a transmission plate 9 being connected to the top of the pair of sliders 7 and the threaded sleeve 8, a support plate 10 being rotatably connected to the top of the transmission plate 9, a pair of transmission rods 6 being hinged to the upright plate 2 on the side near the first motor 3, the other end of the pair of transmission rods 6 being hinged to the support plate 10, an angle adjustment assembly disposed on the support plate 10, a fixing assembly disposed on the top of the angle adjustment assembly, the angle adjustment assembly enabling the fixing assembly to tilt along the width direction of the support plate 10.

[0017] In this embodiment, a pair of upright plates 2 are arranged parallel to each other on the base plate 1; the threaded rod 4 is located between a pair of limiting rods 5 and its two ends are rotatably mounted on the pair of upright plates 2 through bearings; the first motor 3 is a servo motor and its output shaft passes through the upright plates 2 that are close to each other and is connected to the end of the threaded rod 4. The servo motor can precisely control the angle of inclination of the support plate 10 along its length direction; a pair of transmission rods 6 are hinged to the support plate 10 near the middle position.

[0018] As an embodiment of this utility model, the angle adjustment assembly includes multiple uprights 11, a hemispherical shell 12, a rotating shaft 13, a rotating plate 14, a fixing rod 15, and a locking nut 16. The multiple uprights 11 are arranged on the support plate 10, the hemispherical shell 12 is arranged on the multiple uprights 11, the rotating shaft 13 is rotatably arranged on the top of the hemispherical shell 12, the rotating plate 14 is arranged on the rotating shaft 13, the hemispherical shell 12 has a through groove 12-1 along the width direction of the support plate 10, the fixing rod 15 is arranged at the center position of the bottom of the rotating plate 14, the fixing rod 15 passes through the through groove 12-1 and is threaded near the bottom, and the locking nut 16 is threadedly connected to the fixing rod 15 near the bottom.

[0019] In this embodiment, the number of uprights 11 is preferably four and arranged in a square, and the rotating plate 14 is circular in shape and can rotate within the hemispherical shell 12.

[0020] As an embodiment of this utility model, the fixing assembly includes a groove 17, a second motor 18, a bidirectional lead screw 19, a pair of slide rods 20, and a pair of arc-shaped fixing blocks 21. The groove 17 is disposed on the top of the rotating plate 14, and a sliding groove is provided on the groove 17. The bidirectional lead screw 19 is rotatably disposed in the sliding groove. The second motor 18 is disposed on the outer wall of the groove 17 and its output shaft is connected to the bidirectional lead screw 19. The pair of slide rods 20 are slidably disposed in the sliding groove and are threadedly connected to the bidirectional thread of the bidirectional lead screw 19. The pair of arc-shaped fixing blocks 21 are disposed facing each other on the pair of slide rods 20.

[0021] In this embodiment, the second motor 18 is preferably a servo motor to enable precise control of a pair of slide rods 20. The output shaft of the second motor 18 passes through the side wall of the groove 17 and is connected to the end of the bidirectional lead screw 19. The arc-shaped fixing block 21 has a certain width and the opening matches the shape of the turbocharger housing, so that the pair of arc-shaped fixing blocks 21 can firmly fix the turbocharger housing when they move towards each other.

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0023] The working principle and usage process of this utility model are as follows: When in use, the turbocharger housing is first placed between a pair of arc-shaped fixing blocks 21. The second motor 18 is started. The output shaft of the second motor 18 drives the connected bidirectional lead screw 19 to rotate. The bidirectional lead screw 19 drives a pair of sliding rods 20 threaded to it to move towards each other in the sliding groove. The pair of sliding rods 20 drive a pair of arc-shaped fixing blocks 21 to move towards each other, so that the pair of arc-shaped fixing blocks 21 abut against both sides of the turbocharger housing for fixing.

[0024] Secondly, the operator manually moves the fixing rod 15 to move it within the through groove 12-1. Since the top of the fixing rod 15 is fixedly located at the center of the bottom of the rotating plate 14, the movement of the fixing rod 15 within the through groove 12-1 causes the rotating plate 14 and the rotating shaft 13 to rotate. When the rotating plate 14 rotates, it drives the groove 17 to rotate, which in turn drives a pair of sliding rods 20 to rotate. The sliding rods 20 then drive a pair of arc-shaped fixing blocks 21 and the turbocharger housing to rotate, thereby adjusting the angle of inclination of the turbocharger housing along the width of the support plate 10. Once the specified angle is reached, the locking nut 16 is threaded onto the fixing rod 15 near the bottom, causing the locking nut 16 to abut against the outer wall of the hemispherical housing 12, thus fixing the position of the fixing rod 15.

[0025] Finally, the first motor 3 is started. The output shaft of the first motor 3 drives the connected threaded rod 4 to rotate. The threaded rod 4 drives the threaded sleeve 8 to move. The threaded sleeve 8 drives the transmission plate 9 to move. The transmission plate 9 drives the connected pair of sliders 7 and support plate 10 to move. When the pair of sliders 7 move, a pair of limit rods 5 limit them to prevent the transmission plate 9 from deviating when it moves. When the support plate 10 moves, it tilts and causes the pair of transmission rods 6 to rotate around the hinge point with the vertical plate 2. When the angle of the support plate 10 tilts, the hemispherical shell 12 also tilts, which in turn causes the pair of arc-shaped fixing blocks 21 to tilt the turbocharger shell along the length of the support plate 10, thereby adjusting the angle of the turbocharger machining.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
