[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1-Figure 3, an embodiment provided by the utility model: a mechanical processing device for metal castings, comprising a shell 1, a partition 2 is fixedly connected inside the shell 1, a fixed disk 4 is fixedly connected inside the partition 2, a processing head 3 is arranged inside the shell 1, a support column 5 is fixedly connected to the bottom of the fixed disk 4, a motor 6 is fixedly connected to the bottom of the support column 5, a threaded rod 7 is fixedly connected to the output end of the motor 6, a cross bracket 8 is threadedly connected to the outer wall of the threaded rod 7, a limiting assembly is arranged on one side of the cross bracket 8, a connecting rod 10 is rotatably connected to one end of the cross bracket 8, a limiting groove 13 is provided inside the fixed disk 4, an L-shaped bracket 11 is rotatably connected to one end of the connecting rod 10, the outer wall of the L-shaped bracket 11 is slidably connected to the inside of the limiting groove 13, a clamping plate 12 is fixedly connected to the top of the L-shaped bracket 11, and the limiting assembly comprises a cross bar 9, one end of the cross bar 9 is fixedly connected to one side of the cross bracket 8, and the cross bar 9 is slidably connected to the outer wall of the support column 5;
[0032] Specifically, in the process of fixing the casting, the casting is first placed on the fixing plate 4 to ensure that the position of the casting is stable and accurate. Next, the motor 6 starts the output end to drive the threaded rod 7 to rotate. The rotation speed of the threaded rod 7 can be adjusted according to actual needs to meet the requirements for fixing different castings. As the threaded rod 7 rotates, the cross bracket 8 begins to move. The cross bracket 8 and the threaded rod 7 are interconnected through a certain connection structure. When the threaded rod 7 rotates, the cross bracket 8 is driven to descend in a specific direction. In order to ensure that the descent process of the cross bracket 8 does not deviate from the track, the cross bar 9 plays a limiting role on the outer wall of the support column 5, and a certain distance is maintained between the cross bar 9 and the support column 5, so that the cross bracket 8 will not be affected during the descent process. The L-shaped bracket 11 is connected to the cross bracket 8 and the L-shaped bracket 11. When the cross bracket 8 descends, the L-shaped bracket 11 is driven by the connecting rod 10 to slide in the limit groove 13 in the fixed plate 4. Finally, the splint 12 is driven by the L-shaped bracket 11 to fix the casting. The design of the splint 12 fully considers the shape and size of the casting and can fit closely to the surface of the casting to ensure that the casting does not move or shake during the processing. After the casting is fixed, the processing head 3 starts processing. The processing head 3 can be replaced and adjusted according to the processing requirements to meet the processing requirements of different castings.
[0033] Reference Figure 2 and Figure 4A box body 15 is provided on one side of the shell 1, a sealing cover 16 is provided on the top of the box body 15, a water outlet pipe 14 is fixedly connected inside the box body 15, one end of the water outlet pipe 14 is fixedly connected to the inside of the shell 1, a fixing ring 17 is fixedly connected inside the box body 15, a frame 18 is provided inside the box body 15, the outer wall of the frame 18 is slidably connected to the inside of the box body 15, a collecting net 19 is fixedly connected inside the frame 18, a water outlet pipe 20 is fixedly connected inside the box body 15, one end of the water outlet pipe 20 is fixedly connected to a water pump 21, the input end of the water pump 21 is fixedly connected to one end of the water outlet pipe 20, the output end of the water pump 21 is fixedly connected to an annular water pipe 22, the outer wall of the annular water pipe 22 is fixedly connected to a nozzle 23, and the nozzles 23 are arranged in an annular array and fixedly connected to the outer wall of the annular water pipe 22;
[0034] Specifically, first, a proper amount of cooling water will be pre-injected into the shell 1 of the equipment. The cooling water plays a vital role in the processing process. When the processing head 3 starts to work, a large amount of heat will be generated due to its high-speed operation and friction with the casting. At this time, the cooling water can effectively absorb and take away the heat to prevent the processing head 3 and the casting from being damaged due to overheating. In order to realize the circulation of cooling water, a water pump 21 is equipped in the system. The input end of the water pump 21 is connected to the inside of the shell 1 through a water outlet pipe 14, which can pump cooling water from the shell 1 to the inner shell 1. The output end of the water pump 21 is connected to the annular water pipe 22, which is arranged around the processing head 3 and is provided with a plurality of nozzles 23. When the water pump 21 pumps cooling water into the annular water pipe 22, the cooling water will be sprayed out from the nozzles 23 to form a water curtain to directly cool the processing head 3 and the casting. This cooling method is not only highly efficient, but also can ensure that the cooling water is evenly covered on the surface of the processing head 3 and the casting, thereby avoiding the occurrence of local overheating. At the same time, the design of the nozzle 23 can also be adjusted according to the shape of the processing head 3. The shape and size can be flexibly adjusted to meet different processing requirements. During the processing, a large amount of debris will be generated due to the cutting and grinding of metal materials. If these debris are not removed in time, it will not only affect the processing quality, but also may cause damage to the equipment. Therefore, in the cooling water circulation system, a set of debris collection device is also designed. The device is mainly composed of a partition 2, a box 15 and a collection net 19. The partition 2 is located below the processing head 3 and can separate the processing area from the cooling water area. In this way, when the debris generated by the processing head 3 falls, it will be collected by the partition 2 is blocked and falls into the housing 1. At the same time, due to the flow of cooling water, these debris will be driven and flow with the cooling water. Later, when the water pump 21 pumps the cooling water out of the housing 1, these debris will also be sucked in. After the cooling water and the debris are mixed, they will enter the inside of the box 15. In the box 15, a collecting net 19 is set. The collecting net 19 can filter out the debris in the cooling water and make it fall into the collecting net 19 for collection. In this way, the debris can be effectively prevented from being sucked into the water pump 21, thereby protecting the normal operation of the water pump 21.
[0035] Working principle: When the metal casting machining device is used, the casting is first fixed by placing the casting on the fixed plate 4, and then the output end of the motor 6 drives the threaded rod 7 to rotate. When the threaded rod 7 rotates, the cross bracket 8 is driven to descend. The cross bracket 8 is limited on the outer wall of the support column 5 by the cross bar 9. Then, when the cross bracket 8 descends, the connecting rod 10 drives the L-shaped bracket 11 to slide in the limiting groove 13 in the fixed plate 4, and then the L-shaped bracket 11 drives the clamping plate 12 to fix the casting, and then the cross bracket 8 is driven by the connecting rod 10 to drive the clamping plate 12 to fix the casting. The foreman 3 is processed, and then cooling water is injected into the shell 1. When the processing head 3 is processed, the cooling water inside the shell 1 is discharged from the input end of the water pump 21 through the outlet pipe 14, and is pumped into the nozzle 23 on the annular water pipe 22 through the output end of the water pump 21 to spray out, so as to cool the casting and the processing head 3. The debris generated then falls into the shell 1 through the partition 2. While the cooling water is pumped out, the debris is also sucked into the box 15 and falls into the collecting net 19 for filtration and collection, so as to prevent the debris from being sucked into the water pump 21.
