DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figures 1-5 A device for shaping a casting of an automobile motor housing comprises a frame 1, a support plate 2 is rotatably connected to the inside of the frame 1, and a grinder 4 is arranged on the top of the inner wall thereof through a driving member 3, a displacement assembly 5 for moving the motor housing is arranged at the bottom of the support plate 2, and a receiving plate 6 is arranged on the top thereof, and an electric clamp for clamping the motor housing is fixedly installed in the receiving plate 6;

[0023] The grinder 4 includes a grinding head 41 , and is detachably connected to the grinding head 41 via a fixing member 7 .

[0024] It should be supplemented that the driving member 3 includes a driving motor fixedly installed in the frame 1, and a guide rod fixedly installed on the top of the driving motor, and a ball screw is fixedly installed on the shaft end of the driving motor;

[0025] It also includes a cylinder, the shaft end of which is fixedly connected to the grinder 4, and the top of which is fixedly connected to a fixed seat, the fixed seat is threadedly connected to the ball screw and slidably connected to the guide rod, so as to drive the grinding head 41 to move axially.

[0026] Furthermore, the displacement assembly 5 includes a motor 51, a support frame 52 is fixedly installed in the frame 1, the motor 51 is fixedly installed in the support frame 52, and is rotatably connected to a rotating shaft 53, and a transmission gear 54 is fixedly installed between the shaft end of the motor 51 and the rotating shaft 53, and a pair of the transmission gears 54 are engaged and rotated.

[0027] Furthermore, several cams 55 are fixedly installed at the end of the rotating shaft 53. One end of the support plate 2 is rotatably connected to the frame 1, and a pulley 56 is rotatably connected to the bottom of the other end thereof. An annular groove is formed on the periphery of the pulley 56 and abuts against the cam 55 for rotation.

[0028] It is worth mentioning that the volume of the transmission gear 54 fixedly connected to the shaft end of the motor 51 is smaller than that of the other transmission gear 54. The advantage is that when the small gear is engaged with the large gear, the rapid rotation of the small gear can be converted into a larger torque output of the large gear through the gear ratio, ensuring that the rotating shaft 53 can drive the cam 55 to rotate, and then play the role of changing the inclination angle of one end of the support plate 2.

[0029] More specifically, a chute 57 is formed on the end face of the support frame 52. A receiving plate 6 is slidably connected in the chute 57 through a guide rod 58. A cylinder 59 is fixedly installed at the bottom of the support frame 52, and the shaft end of the cylinder 59 is fixedly connected to the bottom of the receiving plate 6.

[0030] Generally speaking, the fixing member 7 includes a mounting seat 71 fixedly connected to the grinding head 41. A convex portion 72 extends upward from the top of the mounting seat 71. A cavity is formed in the convex portion 72 and is inserted into the shaft end of the grinding machine 4.

[0031] Finally, a locking bolt 73 is further included. A stepped hole 74 is formed in the outer wall of the convex portion 72. A through hole 75 matching the stepped hole 74 is formed in the shaft end of the grinding machine 4. The locking bolt 73 is threadedly connected in the stepped hole 74, and the locking bolt 73 passes through the through hole 75.

[0032] It is worth mentioning that the locking bolt 73 matches the stepped hole 74, and the stepped hole 74 is used to limit the locking bolt 73 to prevent the locking bolt 73 from detaching from the mounting seat 71.

[0033] Working mode: During work, the convex portion 72 is inserted into the shaft end of the grinding machine 4, and then the locking bolt 73 is threadedly connected through the stepped hole 74. The locking bolt 73 passes through the through hole 75 and cooperates with the mounting seat 71 to fix the grinding head 41.

[0034] After that, the electric gripper is used to fix the motor housing. When the position of the motor housing needs to be adjusted, the motor 51 drives the rotating shaft 53 to rotate by using a pair of transmission gears 54. While the rotating shaft 53 rotates, the cam 55 abuts against the pulley 56 to achieve the effect of adjusting the inclination angle of the support plate 2, and the cylinder 59 drives the shaft end to extend and retract to drive the receiving plate 6 to move, so as to adjust the position of the motor housing.

[0035] Finally, cooperate with the grinding machine 4 to perform shaping processing on the motor housing.

[0036] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
