Such parts are usually called die castings. Generally, die castings have problems such as gate residue, flash, burr and the like after demolding, and often need to be processed subsequently.

The surface finishing control mechanism is arranged directly below the surface finishing mechanism and is used to control the automatic dynamic rotation and automatic reset of the finished flash punching die casting 2; The edge processing transmission mechanism is arranged between the bidirectional driving unit and the edge processing mechanism and is used for power conversion between the bidirectional driving unit and the edge processing mechanism; The edge processing control mechanism is arranged on the side of the edge processing mechanism and is used to control the automatic dynamic rotation and automatic reset of the finished surface processing die casting 2; The bidirectional driving unit intermittently drives the single-speed transmission unit, and the synchronous driving power conversion mechanism and the edge processing transmission mechanism; The single-speed transmission unit synchronously drives the positioning platform; The single-speed transmission unit intermittently synchronously drives the surface finishing control mechanism; The edge processing mechanism intermittently drives the edge processing control mechanism; The punching mechanism, the surface finishing mechanism, and the edge processing mechanism are sequentially and uniformly arranged along the circumference of the driving mechanism; the punching mechanism, the surface finishing mechanism, the surface finishing control mechanism, and the edge processing control mechanism are all located on the rotation track of the positioning platform in space; the punching mechanism and the surface finishing mechanism are located above the rotation track of the positioning platform; the surface finishing control mechanism and the edge processing control mechanism are located below the rotation track of the positioning platform.

[0020] Specifically, the automatic processing box group is composed of a main installation box body 1 and a base installation box body 3, the main installation box body 1 is fixedly arranged on the base installation box body 3, and the bottom of the main installation box body 1 is located inside the base installation box body 3; More specifically, the sidewall of the main installation box body 1 is provided with a placing avoidance groove 4, which provides avoidance space for the placement of the die casting 2 and facilitates the subsequent maintenance of the structure in the main installation box body 1.

[0021] The placing avoidance groove 4, the punching mechanism, the surface finishing mechanism, and the edge processing mechanism are sequentially and uniformly arranged along the circumference of the driving mechanism in space; When the driving mechanism is in a static state, the placing avoidance groove 4, the punching mechanism, the surface finishing mechanism, and the edge processing mechanism are all in a corresponding state with the positioning platform.

[0022] In the actual application process of the embodiment, when the driving mechanism is in a stationary state, the placement avoidance groove 4, the punching mechanism, the surface finishing mechanism, and the edge processing mechanism are all in a corresponding state with the positioning platform.

Therefore, any one of the remaining to-be-processed die castings 2 is placed on the positioning platform through the placement avoidance groove 4 again. The previous to-be-processed die casting 2 rotates to the position directly below the punching mechanism at this time. In this way, the cycle is repeated, the to-be-processed die castings 2 are effectively and continuously put in, and each to-be-processed die casting 2 can be sequentially and orderly moved to the corresponding position of the punching mechanism, the surface finishing mechanism, and the edge processing mechanism, and then sequentially and orderly and synchronously subjected to the deburring punching, surface cleaning, and deburring and polishing processing, thereby achieving the purpose of simultaneously performing different metal processing under the action of the same driving mechanism, combining different metal processing in a specific way, and effectively and reasonably realizing resource integration. Specifically, the bidirectional driving unit rotates one circle to drive the unidirectional speed change transmission unit to rotate one quarter of a circle, at this time, different to-be-processed die castings 2 are rotated to the corresponding positions of the punching mechanism, surface finishing mechanism and edge processing mechanism, respectively, and the die castings 2 whose burrs have been polished are returned to the positions opposite to the placement avoiding grooves 4 again, then the processed die castings 2 are taken out and new to-be-processed die castings 2 are put in, in the process of one circle rotation of the bidirectional driving unit, the bidirectional driving unit synchronously drives the unidirectional speed change transmission unit, the unidirectional speed change transmission unit not only synchronously drives the positioning platform to dynamically change the positions of the to-be-processed die castings 2, but also drives the surface finishing control mechanism to store energy for dynamic surface processing of the corresponding to-be-processed die castings 2 and automatic resetting of itself; after one circle rotation of the bidirectional driving unit, the bidirectional driving unit reversely rotates one circle, at this time, the unidirectional speed change transmission unit remains in a static state, at this time, the surface finishing control mechanism is in an automatic energy releasing state to dynamically clean the surface of the to-be-processed die castings 2 corresponding to the surface finishing control mechanism and synchronously reset itself; in the process of reverse rotation of the bidirectional driving unit, the bidirectional driving unit synchronously drives the power conversion mechanism and the edge processing transmission mechanism, wherein the power conversion mechanism first drives the surface finishing mechanism to synchronously perform dynamic surface cleaning processing of the die castings 2 corresponding to the surface finishing mechanism by external force, then the power conversion mechanism drives the punching mechanism to perform punching and burr removing processing of the die castings 2 corresponding to the punching mechanism; and the edge processing transmission mechanism synchronously drives the edge processing mechanism to perform burr removing processing of the die castings 2 corresponding to the edge processing mechanism, at this time, the edge processing mechanism synchronously drives the edge processing control mechanism to perform dynamic burr removing processing of the to-be-processed die castings 2 whose surface processing has been completed and automatically stores energy for automatic resetting of the edge processing control mechanism itself; after one circle reverse rotation of the bidirectional driving unit, the bidirectional driving unit restores the original rotation direction, so as to continuously and repeatedly perform synchronous different metal processing of different to-be-processed die castings 2, innovatively, the highly integrated pure mechanical linkage is adopted to specifically combine different metal processing, the PLC controller, a large number of sensors, electromagnetic valves, pneumatic / hydraulic elements and pipelines / circuits are abandoned, the automatic control of different metal processing combination operation is realized by relying on a single driving mechanism, the operation is stable, the structure is substantially simplified, the manufacturing cost, procurement cost, installation and debugging cost and maintenance difficulty and cost are greatly reduced, the control of the single driving mechanism avoids unnecessary resource waste, multiple different processing operations are integrated, multiple processes are completed by one clamping, the production efficiency of specific die castings which have relatively fixed structure and need to be produced in large quantities is effectively improved.

[0037] Specifically, the sliding connection between the punching connecting rod 24 and the general mounting plate 9 is elastically connected through a spring, so as to realize the elastic sliding of the punching connecting rod 24.

[0038] In the actual application process, when the punching and deburring processing of the to-be-processed die casting 2 is performed, a suitable punching die 25 is selected according to the shape of the to-be-processed die casting 2, and then the punching die 25 is detachably arranged at the bottom of the punching connecting rod 24. When the driving motor 5 reversely drives the bidirectional driving shaft 6 to rotate reversely for one circle, the first clamping plate 14 and the first clamping sawtooth gear 13 are in the state of existing clamping interaction force, and then the unidirectional speed change transition shaft 7 is in the synchronous rotation state, that is, the power transmission exists between the bidirectional driving shaft 6 and the unidirectional speed change transition shaft 7 at this time. Then, under the mutual meshing action of the fixed gear ring 15, the center driving gear 16 and the plurality of transmission gears 17, when the unidirectional speed change transition shaft 7 rotates for one circle, the unidirectional driving shaft 8 is synchronously driven to rotate for one quarter of a circle, so that the unidirectional driving shaft 8 drives the positioning platform support 19 to rotate for one quarter of a circle, and therefore the four positioning mounting seats 21 are sequentially driven to rotate for one quarter of a circle. The to-be-processed die casting 2 opposite to the punching die 25 is located directly below the punching die 25. Then, the driving motor 5 drives the bidirectional driving shaft 6 to rotate forwardly for one circle. At this time, the first clamping plate 14 and the first clamping sawtooth gear 13 are in the state of no clamping, and the unidirectional speed change transition shaft 7 is in the state of static, that is, there is no power transmission between the bidirectional driving shaft 6 and the unidirectional speed change transition shaft 7 at this time, that is, the to-be-processed die casting 2 located directly below the punching die 25 is in the state of static at this time. The bidirectional driving shaft 6 is driven to rotate forwardly, and the power conversion mechanism acts on the punching connecting rod 24 to drive the punching die 25 to punch and deburr the to-be-processed die casting 2 corresponding thereto. When the power conversion mechanism and the punching connecting rod 24 are removed from the interaction force, the punching connecting rod 24 drives the punching die 25 to automatically reset so that the punching die 25 and the to-be-processed die casting 2 are away from each other, and the to-be-processed die casting 2 completes the punching and deburring processing. In addition, when the bidirectional driving shaft 6 reversely rotates, the power conversion mechanism and the punching connecting rod 24 are also interacted, but because the bidirectional driving shaft 6 rotates for one circle and the unidirectional driving shaft 8 only rotates for one quarter of a circle, that is, when the bidirectional driving shaft 6 reversely rotates to drive the power conversion mechanism and the punching connecting rod 24 to interact, the to-be-processed die casting 2 does not reach the punching track range of the punching die 25 at this time.

[0039] As a preferred embodiment of the present application, the surface finishing mechanism comprises: The positioning mounting ring 26 is fixedly arranged on the total mounting plate 9. The rotating arc groove 27 is arranged on the side wall of the positioning mounting ring 26.

[0040] In actual application, when the driving motor 5 reverses to change the position of the die casting 2 after the punching process to the position directly below the cleaning brush 32, the surface finishing control mechanism stores energy for dynamic surface treatment of the die casting 2 and automatic reset of the surface finishing control mechanism. When the driving motor 5 reverses for one circle and stops, the dynamic base 20 corresponding to the die casting 2 is elastically clamped and connected with the surface finishing control mechanism. Then the driving motor 5 rotates for one circle. In this process, the surface finishing control mechanism is in an automatic energy release state to dynamically clean the surface of the die casting 2 after the punching process and simultaneously reset itself. That is, the surface finishing control mechanism drives the corresponding dynamic base 20 to rotate to clean the surface of the die casting 2. That is, the die casting 2 is rotated to shake off the punching scraps to clean the surface. At the same time, the driving motor 5 rotates to drive the power conversion mechanism to drive the surface treatment driving rod 28 to move downward. Under the joint action of the rotating guide rod 29 and the rotating arc slot 27, the surface treatment driving rod 28 rotates. At this time, the reset spring 31 is in a stretched state. The surface treatment driving rod 28 drives the cleaning brush 32 to rotate on the die casting 2 directly below the cleaning brush 32 to clean the surface of the die casting 2. That is, the die casting 2 is rotated to clean the surface, and at the same time, the cleaning brush 32 is rotated to clean the surface to clean the surface of the die casting 2. The scraps produced by the punching burr are prevented from interfering with the polishing process. When the power conversion mechanism and the surface treatment driving rod 28 are disconnected, the surface treatment driving rod 28 drives the cleaning brush 32 to reset to move away from the die casting 2. In this process, the surface finishing control mechanism is automatically reset. That is, the die casting 2 is cleaned and at the same time is in a static state. Then the driving motor 5 reverses for one circle. In this process, the dynamic base 20 and the surface finishing control mechanism are automatically disconnected.
