Example

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An auxiliary casting device for casting processing includes a connecting rod 1, four groups of connecting rods 1 are symmetrically distributed, and a pair of symmetrical positioning frames 2 are connected and fixed by the connecting rods 1. The outer wall of the connecting rod 1 is symmetrically fixedly connected with the positioning frame 2, and also includes:

[0029] The chuck 7 is fixedly connected to the outer wall of the top positioning frame 2, and the chuck 7 is symmetrically distributed;

[0030] A driving gear disc 19 is rotatably connected to the inner wall of the positioning frame 2;

When the locking plate 9 is in the state of rotation, the locking block 11 is pressed and moved outward along the locking tooth direction. At this time, the first strong spring 6 and the second strong spring 12 are deformed and contracted under pressure, and the locking block 11 automatically pops out and re-engages in the locking tooth of the chuck 7 after the locking block 11 moves to the next locking tooth, thereby realizing self-locking. When it is rotated to a suitable angle, you only need to hold the handle 4 and tip it over. If contact self-locking is required, you can squeeze and press the handle 5, thereby driving the lifting rod 8 to move, thereby driving the linkage plate 9 to rotate, and then pushing the linkage rod 10 to slide. During the rotation of the linkage plate 9, it slides and rotates adaptively with the linkage rod 10 and the lifting rod 8. The linkage rod 10 moves in the opposite direction to the lifting rod 8, thereby driving the locking block 11 to move out of the chuck 7, thereby releasing the limit self-locking of the chuck 7, facilitating the return of the position of the handle 4, and the operation is simple.

[0032] A driving assembly is arranged on the outer wall of the bottom positioning frame 2;

[0033] The synchronous clamping assembly is arranged on the inner wall of the positioning frame 2 .

[0034] Reference Figure 4 and Figure 5 The synchronous clamping assembly includes a driven gear plate 13 rotatably connected to the inner wall of the positioning frame 2, and the inner wall of the driven gear plate 13 is rotatably connected with a uniformly distributed sliding sleeve 15, and the inner wall of the sliding sleeve 15 is slidably connected with a slider 16, and the inner wall of the slider 16 is rotatably connected with a fixing pin 14, and the fixing pin 14 is fixedly connected to the positioning frame 2, and the end of the slider 16 away from the fixing pin 14 is rotatably connected with an extrusion wheel 17. The driven gear plate 13 rotates in the positioning frame 2, thereby driving the sliding sleeve 15 to move, and the sliding sleeve 15 will squeeze and drive the slider 16 to slide in the sliding sleeve 15 and adjust the angle through the fixing pin 14, thereby realizing the angle adjustment of the extrusion wheel 17 and squeezing and fixing the molten iron hanging bag 18. Due to the symmetrical arrangement of the driven bevel gear 21, its rotation direction is opposite, and because the positioning frame 2 is symmetrically arranged, the time for the extrusion wheel 17 to contact the molten iron hanging bag 18 is the same.

[0035] Reference Figure 5 The driving assembly includes a motor 22 fixedly connected to the outer wall of the bottom positioning frame 2, and the output end of the motor 22 is fixedly connected to a driving bevel gear 23. The output shaft of the motor 22 can be installed with an electromagnetic brake to prevent external force from rotating, and the driving bevel gear 23 is driven to rotate through the output end of the motor 22.

[0036] Reference Figure 5 The outer wall of the driving toothed disc 19 is fixedly connected with a rotating rod 20, and the rotating rod 20 is rotationally connected with the positioning frame 2. The end of the rotating rod 20 away from the driving toothed disc 19 is fixedly connected with a driven bevel gear 21, and the outer wall of the driven bevel gear 21 is meshingly connected with the outer wall of the driving bevel gear 23. The driving bevel gear 23 rotates, and then the meshing transmission driven bevel gear 21 rotates, thereby driving the rotating rod 20 to rotate, and further driving the driving toothed disc 19 to rotate, thereby meshing the transmission driven toothed disc 13 to rotate in the positioning frame 2.

[0037] Reference Figure 1 and Figure 4 The top wall of the pressing handle 5 is fixedly connected with a first strong spring 6, and one end of the first strong spring 6 away from the pressing handle 5 is fixedly connected to the handle 4. The first strong spring 6 cooperates with the second strong spring 12 to provide a strong thrust for the card block 11, so that the chuck 7 and the card block 11 are squeezed against each other and self-locked.

[0038] Reference Figure 1 and Figure 4 A molten iron ladle 18 is arranged on the inner wall of the bottom positioning frame 2, and the outer wall of the molten iron ladle 18 is against the outer wall of the extrusion wheel 17. The molten iron ladle 18 is squeezed and positioned by the extrusion wheel 17. The symmetrical arrangement of the extrusion wheel 17 can fix the top and bottom of the molten iron ladle 18 to avoid accidents during dumping.

[0039] Specifically, when the auxiliary casting device for casting processing is working / in use: first, put the molten iron ladle 18 into the positioning frame 2, and then start the motor 22. The output shaft of the motor 22 can be equipped with an electromagnetic brake to prevent external force from rotating. The driving bevel gear 23 is driven to rotate through the output end of the motor 22, and then the meshing transmission driven bevel gear 21 is rotated, thereby driving the rotating rod 20 to rotate, and further driving the driving toothed disc 19 to rotate, so that the meshing transmission driven toothed disc 13 rotates in the positioning frame 2, thereby driving the sliding sleeve 15 to move, and the sliding sleeve 15 will squeeze and drive the slider 16 to slide in the sliding sleeve 15 and adjust the angle through the fixing pin 14, thereby realizing the angle adjustment of the extrusion wheel 17 and squeezing and fixing the molten iron ladle 18. Due to the symmetrical arrangement of the driven bevel gear 21, its rotation direction is opposite, and because the positioning frame 2 is symmetrically arranged, the extrusion wheel 17 contacts the molten iron ladle 18 for the same time. If it is necessary to flip and dump, it only needs When the handle 4 is held and the pressing handle 5 is driven to rotate, the connecting frame 3 is driven to rotate. During the rotation of the connecting frame 3, since the locking direction of the chuck 7 is clockwise, the locking block 11 will be squeezed and moved outward along the locking direction. At this time, the first strong spring 6 and the second strong spring 12 are compressed, deformed and contracted, and after the locking block 11 moves to the next locking tooth, it automatically pops out and re-enters the locking tooth of the chuck 7, thereby realizing self-locking. When it is rotated to a suitable angle, you only need to hold the handle 4 and tip it over. If contact self-locking is required, you can squeeze the pressing handle 5 to drive the lifting rod 8 to move, thereby driving the linkage plate 9 to rotate, and then pushing the linkage rod 10 to slide. During the rotation of the linkage plate 9, it slides and rotates adaptively with the linkage rod 10 and the lifting rod 8. The linkage rod 10 moves in the opposite direction to the lifting rod 8, thereby driving the locking block 11 to move out of the chuck 7, thereby releasing the limit self-locking of the chuck 7, facilitating the return of the position of the handle 4, and the operation is simple.
