Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a polishing device for automobile castings. Background Technology

[0002] In the automotive manufacturing industry, castings are a common type of component. They are formed by pouring molten metal into a mold and allowing it to cool. While the casting process can quickly mass-produce complex shapes, castings often have defects such as roughness, burrs, and flash on their surface. Therefore, subsequent finishing processes such as polishing and grinding are necessary to meet assembly and appearance requirements.

[0003] Existing automotive casting polishing equipment requires manually placing the castings into iron sand during polishing and manually removing them after polishing. This manual operation is not only cumbersome and reduces work efficiency, but also carries the risk of accidental collisions between different castings during the removal process, resulting in unnecessary scratches or damage to the casting surface and affecting the quality and appearance of the finished product.

[0004] Therefore, there is a need for a polishing device for automotive castings that facilitates material removal. Utility Model Content

[0005] To overcome the cumbersome manual loading and unloading procedures of existing polishing devices, which reduce work efficiency, and the possibility of unintentional collisions between different castings during the extraction process, resulting in unnecessary scratches or damage to the surface of the castings and affecting the quality and appearance of the finished product, this utility model provides a polishing device for automotive castings that facilitates unloading.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a polishing device for automotive castings, comprising a support base, a connecting frame, a connecting frame, a first connecting rod, a second connecting rod, a first elastic element, a first collecting frame, a strainer, a cylinder, and a pusher. The support base is symmetrically connected to the connecting frame, and the two connecting frames are jointly and fixedly connected to the connecting frame. A first connecting rod is slidably disposed inside each of the two connecting frames. A second connecting rod is fixedly connected to one end of each of the two first connecting rods near the connecting frame. The second connecting rod passes through the connecting frame, and two first elastic elements are sleeved on the second connecting rod. The two ends of the first elastic elements are respectively connected to the connecting frame and the second connecting rod. The two first connecting rods are jointly and fixedly connected to the first collecting frame. The first collection frame has a mesh screen at its bottom. A push frame is fixedly connected to one side of the first collection frame. A cylinder is installed on the support near the push frame, and the extension rod of the cylinder can contact the push frame. The frame is characterized by further including a bracket, a rotating plate, a baffle, a moving block, a steel rope, a pin, a buckle, and a second elastic element. The connecting frame has brackets symmetrically arranged. A rotating plate is rotatably connected to the side of the two brackets that are close to each other. A baffle is slidably arranged inside the end of the rotating plate that is close to each other. Two moving blocks are slidably arranged inside the rotating plate. A steel rope is slidably connected to the bottom of the moving block. A pin is provided at the bottom of the steel rope. A buckle is slidably arranged on the pin. Two second elastic elements are connected between the buckle and the pin.

[0007] As a preferred technical solution of this utility model, it also includes a guide frame, steel balls and protective plates. Two protective plates are slidably arranged on the top of the first collection frame. Two steel balls are connected to the left and right sides of each protective plate. Guide frames are installed on the left and right sides of the first collection frame, and the steel balls slide on the guide frames.

[0008] As a preferred technical solution of this utility model, it also includes a guide frame, an air pipe, an air pump, a connecting pipe, a second collection frame, and a sealing frame. The guide frame is installed at the bottom of the first collection frame, and the guide frame passes through the bottom of the connecting frame.

Detailed Implementation

[0023] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Example 1: A polishing device for automotive castings, see reference. Figures 1-3 As shown, the device includes a support base 1, a connecting frame 101, a connecting frame 102, a first connecting rod 2, a second connecting rod 201, a first elastic element 202, a first collecting frame 3, a strainer 301, a cylinder 4, and a pusher 5. The supporting base 1 is symmetrically connected to the connecting frame 101, and the two connecting frames 102 are fixedly connected to each other. The first connecting rod 2 is slidably disposed inside each of the two connecting frames 101. The two ends of the first connecting rods 2 near the connecting frame 101 are fixedly connected to the second connecting rod 201. The second connecting rod 201 passes through the connecting frame 101. Two first elastic elements 202 are sleeved on the second connecting rod 201, with their ends connected to the connecting frame 101 and the second connecting rod 201 respectively. The two first connecting rods 2 are fixedly connected to the first collecting frame 3. The bottom of the first collecting frame 3... The part is equipped with a mesh 301. A pusher frame 5 is fixedly connected to one side of the first collection frame 3. A cylinder 4 is installed on the support base 1 near the pusher frame 5. The telescopic rod of the cylinder 4 can contact the pusher frame 5. The part is characterized by including a bracket 6, a rotating plate 7, a baffle 701, a moving block 8, a steel rope 9, a pin 10, a buckle 11, and a second elastic element 12. The connecting frame 102 is symmetrically equipped with brackets 6. The two brackets 6 are rotatably connected to the side of each other. A baffle 701 is slidably installed in the side of the rotating plate 7 that is close to each other. Two moving blocks 8 are slidably installed in the rotating plate 7. A steel rope 9 is slidably connected to the bottom of the moving block 8. A pin 10 is installed at the bottom of the steel rope 9. A buckle 11 is slidably installed on the pin 10. Two second elastic elements 12 are connected between the buckle 11 and the pin 10.

[0025] When the equipment is needed, first rotate the rotating plate 7 outward, then pour an appropriate amount of iron sand into the first collection frame 3. Next, thread the steel rope 9 through the casting. Then, lift the lower end of the steel rope 9 and insert the pin 10 into the slot on the moving block 8. The second elastic element 12 returns to its original state, causing the buckle 11 to move away from each other, thereby fixing one end of the steel rope 9. Then rotate the rotating plate 7 inward so that the casting is located inside the first collection frame 3. After starting the cylinder 4, the reciprocating motion of the telescopic rod of the cylinder 4 will drive the entire push frame 5 to move up and down, causing the first connecting rod 2 to drive the first collection frame 3 to move up and down. This causes the iron sand in the first collection frame 3 to rub violently against the casting, thereby achieving precision polishing of the casting surface. During polishing, the first elastic element 202 buffers the vibration generated by the up and down movement of the first connecting rod 2. After polishing is completed, the cylinder 4 stops working, and the rotating plate 7 is rotated outward again, causing the moving block 8 to move outward with the rotating plate 7, thereby easily removing the polished casting from the first collection frame 3 and completing the unloading step.

[0026] Example 2: Based on Example 1, refer to Figure 4 As shown, the top of the first collection frame 3 is equipped with two protective plates 15 that slide in a sliding manner. Two steel balls 14 are connected to the left and right sides of each protective plate 15. Guide frames 13 are installed on the left and right sides of the first collection frame 3, and the steel balls 14 slide on the guide frames 13.

[0027] During polishing, the protective plate 15 is moved to the side closer to each other, causing the steel ball 14 to slide the protective plate 15 inward along the guide frame 13, thereby closing the first collection frame 3. This effectively blocks the splashing of iron sand during polishing and ensures the safety of the operator. After polishing is completed, the protective plate 15 is moved to the side further away from each other, causing the steel ball 14 to slide the protective plate 15 outward along the guide frame 13, thus opening the first collection frame 3.

[0028] See Figure 5 and Figure 7 As shown, a guide frame 16 is installed at the bottom of the first collection frame 3. The guide frame 16 passes through the bottom of the connecting frame 102. The bottom of the guide frame 16 is connected to and communicates with an air pipe 17. An air pump 18 is installed on the air pipe 17. A connecting pipe 19 is connected to the end of the air pump 18 away from the air pipe 17. A second collection frame 20 is fixedly connected to the support base 1. One end of the connecting pipe 19 communicates with the second collection frame 20. A sealing frame 21 is provided on the second collection frame 20.

[0029] When the equipment is started to grind the casting, it will generate debris. The debris will fall into the guide frame 16. The air pump 18 is started. The air pump generates airflow through the air pipe 17 and the connecting pipe 19 to suck the debris in the guide frame 16 into the second collection box 20, realizing the centralized collection of debris for subsequent processing. After the second collection box 20 is full of debris, the sealing frame 21 can be opened to process the debris.

[0030] See Figure 3 , Figure 6 and Figure 7 As shown, two wedge blocks 23 are slidably arranged on one end of the two rotating plates 7 that are close to each other. The wedge blocks 23 limit the baffle 701. A push block 22 is slidably arranged on the rotating plate 7. The push block 22 is located between the two wedge blocks 23. The push block 22 can squeeze the wedge blocks 23. A dustproof net 24 is provided on the sealing frame 21. A T-block 25 is slidably arranged on the steel rope 9.

[0031] When it is necessary to remove the movable block 8, rotate the rotating plate 7 outward and push the push block 22 to the side away from each other. This will cause the push block 22 to squeeze the wedge block 23 to move to the side away from each other and no longer limit the baffle 701. Then remove the baffle 701 from the rotating plate 7 to complete the unlocking. Remove the movable block 8 for replacement. In order to prevent debris from splashing out of the second collection box, the dustproof net can block the debris in the second collection box. By pulling the T-block upward and engaging it with the detached steel rope, it is easy to directly replace the steel rope.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
