[0079] In this embodiment, the rack 16 is in two groups; when the spur gear 17 rotates, the two groups of racks 16 will move horizontally in opposite directions; the rack 16 simultaneously drives the support base 15 to move.

[0080] The output end of the first electric push rod 18 is fixedly connected with the rack 16.

[0081] In this embodiment, the model of the first electric push rod 18 is selected according to actual needs, which meets the working conditions; the output end of the first electric push rod 18 can drive a group of racks 16 to move.

[0082] The aluminum magnesium alloy casting size detection device further comprises a support 3; the support 3 is arranged above the scale plate 2 and is fixedly connected with the scale plate 2; the surface of the support 3 is provided with a sliding rail.

[0083] The aluminum magnesium alloy casting size detection device further comprises a circumference detection structure; the circumference detection structure is connected with the support 3 and is used for detecting the circumference of the casting.

[0084] As shown in Figure 2 and Figure 3 , the circumference detection structure comprises a moving block 19, a connecting plate 20, a first rotating wheel 21, a second rotating wheel 22 and a second electric push rod 23.

[0085] The moving block 19 is arranged in the sliding rail and is slidingly connected with the support 3 through the sliding rail.

[0090] In this embodiment, a flexible ruler is wound around the surfaces of the first rotating wheel 21 and the second rotating wheel 22, and the zero mark of the flexible ruler is located on the first rotating wheel 21. Since the first rotating wheel 21 does not rotate, the zero mark is always located close to the casting. When the connecting plate 20 rotates, the second rotating wheel 22 is driven to rotate around the axis of the first rotating wheel 21, and the flexible ruler is wound around the casting to measure the circumference of the casting.

[0091] The output end of the second electric push rod 23 is fixedly connected with the moving block 19.

[0092] In this embodiment, the model of the second electric push rod 23 is selected according to actual needs, as long as the working conditions are met; the output end of the second electric push rod 23 can drive the moving block 19 to move, so that the zero mark on the first rotating wheel 21 is attached to the casting.

[0093] Working principle:

[0094] When the aluminum-magnesium alloy casting size detection device is in use, the casting is placed on the detection workbench 1, and the fixed abutting piece 4 is located inside the casting. At this time, the user rotates the hand wheel 14 to drive the threaded rod 11 to rotate, and the threaded rod 11 drives the moving piece 10 to move horizontally. The moving piece 10 drives the rotating piece 7 to rotate through the sliding movement between the cylindrical pin and the sliding groove, and the rotating piece 7 simultaneously drives the fixed abutting piece 4 to rotate along the connection between the supporting piece 8, so as to change the inclination angle of the fixed abutting piece 4, so that the fixed abutting piece 4 is closely attached to the casting without gaps, thereby ensuring the accuracy of the detection result.

[0095] Subsequently, the first electric push rod 18 is adjusted, so that the output end of the first electric push rod 18 drives a group of racks 16 to move outward. The group of racks 16 drives the spur gears 17 to rotate, and the spur gears 17 drive another group of racks 16 to also move outward, and the movement directions of the two groups of racks 16 are opposite. The racks 16 drive the fixed abutting piece 4 to move through the angle adjusting device, so that the fixed abutting piece 4 contacts the inner wall of the casting. At this time, the inner diameter size of the casting is calculated by observing the scale of the fixed abutting piece 4 on the scale plate 2, and vice versa, so as to measure the outer diameter size of the casting.

[0096] When the peripheral circumference of the casting needs to be detected, the second electric push rod 23 is adjusted so that the output end of the second electric push rod 23 pushes the moving block 19 to move horizontally; the moving block 19 drives the first rotating wheel 21 to move at the same time, so that the zero scale on the first rotating wheel 21 is attached to the casting; at this time, the second rotating wheel 22 is driven to revolve by rotating the connecting plate 20, and the second rotating wheel 22 will wind the flexible ruler on the casting; the circumference of the casting is obtained by observing the scale on the flexible ruler, and the use of the device is completed.

[0097] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
