[0037] Please refer to Figure 1-8A stable-running telescopic casting machine material receiving mechanism shown in the figure includes a column 1 arranged on one side of the casting machine. A rotating assembly 2 is provided on the column 1. A transfer assembly 3 is provided on the rotating assembly 2. A material receiving assembly 4 is provided on the transfer assembly 3. The material receiving assembly 4 can move back and forth driven by the transfer assembly 3, and the rotating assembly 2 can drive the transfer assembly 3 to move up and down. Driving the material receiving assembly 4 to move back and forth by the transfer assembly 3 adapts to the adjustment of the position of the material receiving assembly 4 when producing products of different specifications. The rotating assembly 2 controls the transfer assembly 3 and the material receiving assembly 4 to rotate in the horizontal position to enter and leave the material receiving area.

[0038] The rotating assembly 2 includes a set of pedestal bearings 201 connected to the column 1, a rotating shaft 202, a driving motor 203, and a rotating arm 204. The set of pedestal bearings 201 are respectively arranged at both ends of the column 1. The rotating shaft 202 is connected to the pedestal bearings 201 and can rotate. At the same time, one end close to the driving motor 203 is also connected to the rotating shaft of the driving motor 203 through a coupling. And the driving motor 203 is connected to the side of the pedestal bearing 201 close to the driving motor 203 through a connecting piece. One end of the rotating arm 204 is connected to the rotating shaft 202 and can rotate with the rotation of the rotating shaft 202. The driving motor 203 rotates to provide rotational power to the rotating shaft 202, and then drives the transfer assembly 3 to rotate synchronously with the rotating shaft 202.

[0039] The transfer assembly 3 includes a hydraulic cylinder 301, a connecting block 302, a roller mounting plate 303, a sliding side plate 304, a connecting bottom plate 305, rollers 306, bull's eye wheels 307 and a linear guide pair 308. The cylinder body of the hydraulic cylinder 301 is connected to the rotating arm 204, and the telescopic rod of the hydraulic cylinder 301 is connected to the connecting block 302. The upper end of the connecting block 302 is also fixedly connected to the connecting bottom plate 305. A set of roller mounting plates 303 are respectively arranged on both sides of the rotating arm 204, and a linear guide pair 308 is provided at the upper end of each roller mounting plate 303. The slider on the linear guide pair 308 is connected to the connecting bottom plate 305. A plurality of rollers 306 and bull's eye wheels 307 are arranged on the roller mounting plate 303 at intervals. The roller 306 is arranged on the roller mounting plate 303 through a roller 306 shaft. The base of the bull's eye wheel 307 is fixedly connected to the roller mounting plate 303. A set of sliding side plates 304 are respectively arranged on both sides of the connecting bottom plate 305, and a rectangular groove 309 and an arc groove 310 are provided on the sliding side plate 304. The rectangular groove 309 is matched with the roller 306, and the arc groove 310 is matched with the ball on the bull's eye wheel 307. When the transfer assembly 3 works, the hydraulic cylinder 301 works, and its telescopic rod drives the connecting block 302 to move linearly, thereby driving the material receiving assembly on the connecting bottom plate 305 to move. When the connecting bottom plate 305 moves, the cooperation between the roller 306 and the sliding side plate 304 improves the stability of the movement, and the cooperation between the ball on the bull's eye wheel 307 and the arc groove 310 reduces the inclination and shaking of the connecting bottom plate 305, further ensuring the stability of the operation. A set of linear guide pairs 308 are added between the connecting bottom plate 305 and the roller mounting plate 303, which increases the connection strength between the connecting bottom plate 305 and the roller mounting plate 303 while providing stable guiding ability, and is more conducive to the stability of the movement of the connecting bottom plate 305.

[0040] The material receiving assembly 4 includes a material receiving chassis 401, buffer springs 402 and T-shaped guide rods 403. The buffer springs 402 are sleeved on the T-shaped guide rods 403.

A plurality of buffer springs 402 and T-shaped guide rods 403 are provided and divided into two groups and arranged on both sides of the material receiving chassis 401. In order to reduce the damage to the casting caused by the impact between the casting and the material receiving chassis 401, the material receiving chassis 401 realizes the function of absorbing the impact force of the casting falling onto the material receiving chassis 401 through the designed buffer springs 402 and T-shaped guide rods 403. When the casting falls into the material receiving chassis 401, the material receiving chassis 401 presses down the buffer spring 402 due to the combined action of the self-gravity and impact force of the casting. The buffer spring 402 is compressed, and at the same time, the T-shaped guide rod 403 moves in the guide sleeve to transfer the impact force caused by the casting to the material receiving chassis 401.

[0041] Specifically, an installation cavity 205 is provided at one end of the rotating arm 204 away from the rotating shaft 202. The hydraulic cylinder 301 and the connecting block 302 are both arranged in the installation cavity 205, and a protective cover for protecting the hydraulic cylinder 301 is provided at the upper part of the installation cavity 205. An anti-collision block 206 is also provided in the installation cavity 205, and the anti-collision block 206 is fixedly connected to an inner side edge of the installation cavity 205 away from the rotating shaft 202.

[0042] Specifically, in order to increase the load-bearing capacity of the rotating arm 204, a load-bearing plate 207 is provided on the rotating arm 204. A set of the load-bearing plates 207 are respectively arranged on both sides of the installation cavity 205, and a set of roller mounting plates 303 are fixedly connected to the load-bearing plate 207. At the same time, in order to improve the load-bearing capacity and overall rigidity of the connecting bottom plate 305, a first reinforcement plate 311 and a second reinforcement plate 312 are provided on the upper end surface of the connecting bottom plate 305. A plurality of the first reinforcement plates 311 and the second reinforcement plates 312 are arranged perpendicular to each other.

[0043] Specifically, a snap ring for preventing the T-shaped guide rod 403 from falling off is provided at one end of the T-shaped guide rod 403 away from the material receiving tray.

[0044] Specifically, a top block 5 is further provided on the lower end surface of one side edge of the connecting bottom plate 305. A limiting mounting plate 6 is provided on the side edge of the load-bearing plate 207 on the same side, and a set of travel switches 7 are provided on the limiting mounting plate 6. Adjusting holes 8 corresponding to the positions of the set of travel switches 7 are provided on the limiting mounting plate 6. The adjusting holes 8 are in a waist-shaped structure, and the travel switches 7 are connected to the limiting mounting plate 6 by passing through the adjusting holes 8 in a manner of being connected by bolts and nuts.

[0045] In this embodiment, the cooperation of two travel switches 7 and the top block 5 controls the operation of the hydraulic cylinder 301 through an external control device, so as to realize the control of the transfer distance of the transfer assembly 3.

[0046] Working principle: When receiving materials is required, the rotating component 2 operates to drive the transfer component 3 and the material receiving component 4 to rotate to the blanking position. Then, the transfer component 3 pushes the material receiving component 4 to the accurate area where the castings are blanked. After the castings are blanked, when the castings fall onto the material receiving chassis 401, the material receiving chassis 401 presses down the buffer spring 402 due to the gravity and impact force of the castings themselves. The buffer spring 402 is compressed, and at the same time, the T-shaped guide rod 403 moves out of the guide sleeve to achieve the transfer of the impact force caused by the castings to the material receiving chassis 401. Then, the transfer component 3 moves the material receiving component 4 away from the blanking position. The hydraulic cylinder 301 operates to drive the connecting block 302 to drive the connecting bottom plate 305 to move, thereby driving the material receiving component 4 to move. During this process, the roller 306 rolls in the rectangular groove 309 on the sliding side plate 304, and the ball of the bull's eye wheel 307 contacts the arc surface of the arc groove 310 to form relative movement. In addition, the linear guide pair 308 is also connected to the connecting bottom plate 305. In such a movement situation, the shaking of the connecting bottom plate 305 and the material receiving component 4 provided thereon can be reduced, and the operating stability can be improved.
