Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a polishing and grinding device for metal castings. Background Technology

[0002] Metal castings are basic parts formed by injecting molten metal into a mold. They are widely used in machinery, automobiles and other fields. They have complex geometric shapes, but their surfaces often have defects such as burrs and oxide layers. Polishing and grinding equipment is an automated device used to improve the surface quality of these castings. It removes defects through high-speed rotation or vibration grinding, achieving high-precision surface finish and meeting industrial-grade dimensional tolerance and appearance requirements.

[0003] For example, application number CN202322910989.7 proposes a high-efficiency metal casting polishing machine, including a base, a protective frame on the base, a support plate on one side of the protective frame, a slidable electric slider on the support plate, a first motor fixedly mounted on the electric slider, the output end of the first motor connected to a first rotating shaft, the first rotating shaft passing through the side wall of the protective frame and fixedly connected to a grinding plate, abrasion paper on the grinding plate, a retaining device for holding the metal casting at the upper end of the protective frame, and a rotating device at the lower end of the protective frame. In this metal casting polishing machine, the first motor on the side of the protective frame drives the grinding plate to rotate, causing the abrasion paper on the grinding plate to polish the metal casting. The retaining device and rotating device at the upper end of the protective frame can cooperate to fix the columnar metal casting and allow the metal casting to move up and down and rotate, thereby enabling the grinding plate to completely polish the side of the columnar metal casting.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that polishing machines can only polish one side of a casting, requiring manual flipping for further polishing and thus reducing polishing efficiency, its use in fixing the casting solely on the top and bottom sides is insufficient to provide adequate stability for curved, irregular, or complex-shaped castings. This results in the casting shaking or shifting during polishing, affecting polishing quality and efficiency. Furthermore, the polishing process generates a large amount of dust and noise, which can impact the health of operators and the working environment. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a metal casting polishing and grinding device with the advantages of auxiliary clamping and protection. It solves the problem that fixing the casting only by the upper and lower sides cannot provide sufficient stability for curved, irregular, and complex or irregular castings, resulting in the casting shaking or displacement during the polishing process, affecting the polishing quality and efficiency. In addition, the polishing process generates a lot of dust and noise, which will affect the health of the operators and the working environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal casting polishing and grinding device, comprising a base, a support plate, a grinding device, an upper top plate, and a lower top plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the present invention provides a metal casting polishing and grinding device 3, including a base 1, a support plate 2, a grinding device 3, an upper top plate 4, and a lower top plate 5. The support plate 2 is fixedly connected to the rear side of the top of the base 1, the grinding device 3 is fixedly connected to the left side of the top of the base 1, the upper top plate 4 is fixedly connected to the front side of the top of the support plate 2, and the lower top plate 5 is fixedly connected to the right side of the top of the support plate 2. A protective cover 6 is fixedly connected to the outer side of the top of the base 1, and a circular mounting plate 7 is fixedly connected to the top of the lower top plate 5. The top of the circular mounting plate 7 has a strip groove 8, which has six grooves and is distributed in a ring at equal intervals. A mounting block 9 is provided on the top of the strip groove 8, and an extension clamping mechanism 10 is provided on the top of the mounting block 9.

[0022] refer to Figure 3 The extended clamping mechanism 10 includes a screw sleeve 101, a screw rod 102, a clamping plate 103, and a handwheel 104. The screw sleeve 101 is fixedly connected to the top of the mounting block 9, the screw rod 102 is threadedly connected to the right side of the screw sleeve 101, the clamping plate 103 is fixedly connected to the left end of the screw rod 102, and the handwheel 104 is fixedly connected to the right end of the screw rod 102.

[0023] As a technical optimization of this utility model, by setting an extension clamping mechanism 10, the screw 102 can move left and right within the screw sleeve 101, thereby driving the clamping plate 103 to clamp and fix castings of different sizes. The handwheel 104 allows the operator to operate the screw 102 without other tools, ensuring that the casting remains stable during the polishing process and improving the polishing quality.

[0024] refer to Figure 3The two sides of the strip groove 8 are provided with sliding grooves 11, and the inner side of the sliding groove 11 is movably connected to the slider 12. The top of the slider 12 is fixedly connected to the bottom of the mounting block 9.

[0025] As a technical optimization of this utility model, by setting the sliding groove 11 and the slider 12, the mounting block 9 can slide inward along the strip groove 8 through the cooperation of the slider 12 and the sliding groove 11, thereby facilitating the adjustment of the radial position of multiple clamping stations and improving the flexibility and adaptability of the device.

[0026] refer to Figure 3 An adjustment groove 13 is provided on the rear side of the mounting block 9. An operating block 14 is slidably connected to both sides of the inner side of the adjustment groove 13. A locking groove 15 is provided on the inner side of the slide groove 11. Several locking grooves 15 are provided and are evenly distributed. The outer side of the bottom of the operating block 14 cooperates with the locking groove 15. A spring 16 is fixedly connected to the inner side of the operating block 14.

[0027] As a technical optimization of this utility model, by setting an adjustment groove 13, an operating block, a locking groove 15 and a spring 16, the operating block 14 can compress the spring 16 inward when pressed, thereby disengaging from the locking groove 15, quickly unlocking the position of the mounting block 9, and releasing the operating block 14 after adjusting to the required position, so that the spring 16 resets and locks, thereby improving the convenience of equipment clamping and processing stability.

[0028] refer to Figure 1 An operating window 17 is provided on the front side of the protective cover 6, and a sealing door 18 is movably connected to the bottom of the front side of the operating window 17.

[0029] As a technical optimization of this utility model, by setting up an operation window 17 and a sealing door 18, the operation window 17 and the sealing door 18 form an openable and closable channel. When the casting is loaded or unloaded, the channel is partially opened to reduce dust overflow. When the casting is placed in, the channel is closed to maintain the airtightness of the protective cover 6, thereby reducing the pollution of the operating environment by noise and metal debris.

[0030] refer to Figure 1 An observation port 19 is provided on the front side of the sealed door 18, and a transparent observation window 20 is fixedly connected to the inner side of the observation port 19.

[0031] As a technical optimization of this utility model, by setting an observation port 19 and a transparent observation window 20, the transparent observation window 20 allows operators to conveniently observe the polishing status inside the equipment in real time without opening the sealed door 18, thereby avoiding the risk of dust leakage caused by frequent opening and closing and ensuring the continuity of processing quality.

[0032] refer to Figure 2 The front top of the sealing door 18 is fixedly connected to the two sides of the support column 21, and the rear sides of the sealing door 18 are movably connected to the baffle 22 by the shaft pin.

[0033] As a technical optimization of this utility model, by setting up a support column 21 and a baffle 22, when the sealed door 18 is opened forward, the support column 21 can provide support to prevent the door from directly contacting the ground. Then, after the door is lowered, the baffle 22 slides inward to cover the top of the operating window 17, forming a temporary storage platform, thereby temporarily storing the castings to be processed and the castings that have been processed, reducing secondary pollution caused by the stacking of workpieces on the ground.

[0034] The working principle and usage process of this utility model are as follows: First, open the sealing door 18. The support column 21 will then support the door, preventing it from directly contacting the ground. Next, place the casting on top of the lower top plate 5. Then, press the operating block 14 to compress the spring 16 and disengage it from the locking groove 15, quickly unlocking the mounting block 9. Adjust the mounting block 9 to the desired position according to the size of the casting, then release the operating block 14. The spring 16 will reset and lock, fixing the position of the mounting block 9. Then, rotate the handwheel 104 to move the screw 102 within the screw sleeve 101, adjusting the position of the clamping plate 103. The casting is further clamped to ensure its stability during polishing. After the casting is installed and fixed, the sealing door 18 is closed to maintain the airtightness of the protective cover 6, thereby reducing dust leakage and minimizing noise and metal debris pollution to the environment. During the polishing process, the operator can monitor the polishing status in real time through the transparent observation window 20. When polishing is completed, the sealing door 18 is opened and the baffle 22 at the top of the sealing door 18 is closed inward. Then the casting is taken out. At this time, the baffle 22 can be used as a temporary storage platform to facilitate the operator to place and organize the casting, thereby achieving the effect of auxiliary clamping and fixing.

[0035] In summary, this metal casting polishing and grinding device 3, by setting up a protective cover 6 and an extended clamping mechanism 10, allows the protective cover 6 to prevent dust generated during the grinding process from leaking out, and the extended clamping mechanism 10 to clamp the casting from multiple angles. This solves the problem that fixing the casting only from the top and bottom sides cannot provide sufficient stability for curved, irregular, or complex-shaped castings, which can cause the casting to shake or shift during polishing, affecting the polishing quality and efficiency. Furthermore, the polishing process generates a large amount of dust and noise, which can affect the health of operators and the working environment.
