Description

Technical Field

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

[0002] Castings are shaped metal objects obtained through various casting methods. This involves pouring, injecting, suction, or other casting methods into a pre-prepared mold, cooling it, and then processing it through grinding and other methods to obtain an object with a specific shape, size, and performance. Castings have a long history of application. In ancient times, people used castings to make household utensils. In modern times, castings are mainly used as blanks for machine parts; some precision castings can also be used directly as machine parts. Castings account for a large proportion of mechanical products. For example, in tractors, castings account for about 50-70% of the total weight; in agricultural machinery, 40-70%; and in machine tools and internal combustion engines, 70-90%. Among various types of castings, those for machinery are the most diverse, have the most complex shapes, and are used in the largest quantities, accounting for about 60% of total casting production. Next are steel ingot molds for metallurgy, pipes for engineering, and some tools for daily life. After casting is formed, burrs or scratches may appear on the surface, requiring grinding and polishing.

[0003] A search revealed Chinese patent CN213258838U, which discloses a metal casting grinding and polishing device. The device includes a base; a hydraulic cylinder is installed inside the base, with its piston rod extending through the top of the base. A housing is fixed to the end of the piston rod, and a slot is formed at the top of the housing. An electric push rod is housed within the slot, and a movable clamping block is connected to the end of the push rod. A fixed clamping block is located on the right side of the top of the housing. Support rods are fixed to both sides of the top of the base, with their ends fixed to the bottom of a housing. A grinding groove is formed inside the housing, and a motor is located in the center of the top of the housing. An air hood is located on the right side of the top of the housing. This invention, by incorporating a grinding mechanism and a dust collection mechanism within the grinding groove, ensures that all dust and impurities generated during the grinding and polishing process are completely collected. Furthermore, the forging is positioned on a quick-clamping mechanism, greatly improving the convenience of the overall equipment during operation.

[0004] However, the above design still has shortcomings. In the above design, the support mechanism cannot be effectively adjusted during grinding and polishing, which requires the metal casting to be moved repeatedly to achieve grinding and polishing of different positions of the metal casting, thereby reducing the efficiency of grinding and polishing.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a casting grinding and polishing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a casting grinding and polishing device, comprising a C-shaped plate, a control panel mounted on the front end face of the C-shaped plate, support blocks fixedly connected to the four corners of the bottom of the C-shaped plate, a hydraulic push rod mounted on the top of the C-shaped plate, a grinding motor fixedly mounted on the output end of the hydraulic push rod, a polishing wheel fixedly connected to the output end of the grinding motor, a rotating plate rotatably mounted on the lower right side of the C-shaped plate, a handle fixedly connected to the right side of the rotating plate, a transmission rod fixedly connected to the left side of the rotating plate, a threaded rod fixedly connected to the left side of the transmission rod, a moving block threadedly connected to the outer wall of the threaded rod, a crossbar movably mounted through the lower surface of the moving block, a transmission block fixedly connected to the top of the moving block, and a placement platform fixedly connected to the top of the transmission block.

[0011] As a further embodiment of this utility model: two placement plates are fixedly connected to the left outer wall of the C-shaped plate, and a placement groove is provided on the upper surface of the placement plate.

[0012] As a further embodiment of this utility model: a storage box is movably provided inside the placement slot, a handle is fixedly connected to the left side of the storage box, and multiple partitions are provided inside the storage box.

[0013] This utility model has the following beneficial effects:

[0014] (1) Through the structural design of the C-shaped plate, the placement table, the grip rod, the transmission rod, the rotating plate, the transmission block, the moving block and the threaded rod, it is possible to facilitate grinding and polishing different positions of the metal casting, thereby improving the grinding and polishing efficiency.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 An embodiment of this utility model provides a casting grinding and polishing device, including a C-shaped plate 2, a control panel 1 installed on the front end face of the C-shaped plate 2, support blocks 5 fixedly connected to the four corners of the bottom of the C-shaped plate 2, a hydraulic push rod 3 installed on the top of the C-shaped plate 2, a grinding motor 26 fixedly installed at the output end of the hydraulic push rod 3, a polishing wheel 6 fixedly connected at the output end of the grinding motor 26, a rotating plate 9 rotatably arranged on the lower right side of the C-shaped plate 2, a handle 7 fixedly connected to the right side of the rotating plate 9, a transmission rod 8 fixedly connected to the left side of the rotating plate 9, a threaded rod 24 fixedly connected to the left side of the transmission rod 8, a moving block 23 threadedly connected to the outer wall of the threaded rod 24, a crossbar 25 movably arranged through the lower end surface of the moving block 23, a transmission block 22 fixedly connected to the top of the moving block 23, and a placement table 4 fixedly connected to the top of the transmission block 22.

[0028] Specifically, such as Figure 1, Figure 2 and Figure 5 As shown, when polishing a metal casting, the rotating plate 9 can be rotated by holding the handle 7. The rotation of the rotating plate 9 drives the threaded rod 24 to rotate via the transmission rod 8. The rotation of the threaded rod 24 drives the moving block 23 to move, which in turn drives the transmission block 22 to move. The movement of the transmission block 22 then moves the metal casting on the placement table 4. By reasonably controlling the direction of movement of the metal casting, the purpose of grinding and polishing different positions of the metal casting can be achieved. This solves the problem that during grinding and polishing, the support mechanism cannot be effectively adjusted, requiring repeated movement of the metal casting to achieve grinding and polishing of different positions, thus reducing the efficiency of grinding and polishing.

[0029] The upper surface of the placement platform 4 has two grooves 15, the bottom of the grooves 15 has a sliding groove 21, the inner wall of the sliding groove 21 is slidably connected to a slider 20, the top of the slider 20 is fixedly connected to a transmission plate 19, the middle of the transmission plate 19 is movably connected to a limit rod 16, the side of the two transmission plates 19 that is far apart from each other is fixedly connected to a spring 17 below the limit rod 16, the side of the two transmission plates 19 that is close to each other is fixedly connected to a limit frame 18 above the limit rod 16, the left outer wall of the U-shaped plate 2 is fixedly connected to two placement plates 12, the upper surface of the placement plate 12 has a placement groove 11, the inside of the placement groove 11 is movably connected to a storage box 14, the left side of the storage box 14 is fixedly connected to a handle 10, and the inside of the storage box 14 is provided with multiple partition plates 13;

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when it is necessary to fix the metal casting, first move the two limiting frames 18 in a direction away from each other. When the limiting frames 18 move to the appropriate position, place the metal casting between the two limiting frames 18. Then release the limiting frames 18. At this time, the elasticity of the spring 17 can be used to drive the two limiting frames 18 to move in a direction closer to each other until they contact the outer walls of both sides of the metal casting and effectively clamp and fix it, thereby completing the limiting of the metal casting. At the same time, by reasonably adjusting the distance between the two limiting frames 18, it is possible to avoid limiting metal castings of different widths, thereby improving the practicality of the device.

[0031] The storage box 14 and the partition plate 13 facilitate the temporary storage and separation of polished metal castings, making it easier for staff to process them uniformly later and improving their work efficiency. When the storage box 14 is full, the handle 10 can be lifted to move the storage box 14 upwards until the bottom of the storage box 14 is detached from the placement slot 11. Then, the metal castings in the storage box 14 can be sorted out, and the empty storage box 14 can be put back into the placement slot 11 for temporary storage of polished metal castings later.

[0032] Working principle: In this application, when grinding a metal casting is required, the two limiting frames 18 are first moved away from each other. When the limiting frames 18 move to the appropriate position, the metal casting is placed between the two limiting frames 18. Then, the limiting frames 18 are released. At this time, the elasticity of the spring 17 can be used to drive the two limiting frames 18 to move closer to each other until they contact the outer walls of both sides of the metal casting and effectively clamp and fix them. Then, the hydraulic push rod 3 is activated, which drives the polishing wheel 6 to move downwards through the output end of the hydraulic push rod 3 until it contacts the top of the metal casting. When the grinding motor 26 is started, the polishing wheel 6 can be rotated through the output end of the grinding motor 26, thereby performing grinding and polishing operations on the surface of the metal casting. Secondly, during the grinding process of the metal casting, the rotating plate 9 can be rotated by holding the handle 7. The rotation of the rotating plate 9 drives the threaded rod 24 to rotate through the transmission rod 8. The rotation of the threaded rod 24 drives the moving block 23 to move. The movement of the moving block 23 drives the transmission block 22 to move. The movement of the transmission block 22 drives the metal casting on the placement table 4 to move. By reasonably controlling the movement direction of the metal casting, the purpose of grinding and polishing different positions of the metal casting can be achieved.
