Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices for valve body processing, specifically a grinding device for valve body processing. Background Technology

[0002] Grinding is a crucial step in valve body manufacturing, aiming to remove burrs, scale, and other imperfections from the valve body surface, improve surface smoothness, and ensure the valve body's sealing performance and overall quality. However, existing valve body grinding equipment generally has certain shortcomings.

[0003] For example, most grinding devices are difficult to adapt to valve bodies of different shapes and sizes. When grinding valve bodies with complex structures, the grinding head cannot be adjusted flexibly, resulting in uneven grinding and affecting the quality of the valve body. Moreover, the grinding components of traditional grinding devices are inconvenient to replace, which increases equipment maintenance costs and downtime, and reduces production efficiency. Therefore, a grinding device for valve body processing is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problems of existing grinding devices being difficult to adapt to different valve bodies, uneven grinding, and inconvenient replacement of grinding components.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A grinding device for valve body processing includes a grinding machine body, a rotating head is rotatably connected to the bottom of the grinding machine body, a fixing mechanism is fixedly connected to the bottom of the rotating head, a rotating rod is clamped inside the fixing mechanism, an adaptive mechanism is fixedly connected to the bottom of the rotating rod, and a grinding mesh is fixedly connected to the outside of the adaptive mechanism.

[0008] The adaptive mechanism includes a mounting head, which is fixedly connected to the bottom of the rotating rod. Multiple first fixing blocks, arranged in a ring and equidistant from each other, are fixedly connected to the outer side of the mounting head. Two first connecting rods, arranged in an alternating vertical arrangement, are rotatably connected to the interior of each of the multiple first fixing blocks. Second fixing blocks are rotatably connected to the outer sides of the first connecting rods on both sides, and are arranged symmetrically vertically. Second connecting rods, arranged in an alternating front-to-back arrangement, are rotatably connected to the interior of each of the second fixing blocks on both sides. The other ends of the two second connecting rods on the same side are rotatably connected to the same third fixing block. The interiors of the second and third fixing blocks on both the upper and lower sides are rotatably connected to the same reinforcing ring.

[0009] The beneficial effects of this utility model are:

[0010] By incorporating an adaptive mechanism, the position and shape of the grinding mesh can be automatically adjusted according to the shape and size of the valve body, achieving uniform grinding of valve bodies of different shapes and sizes. The design of the fixing mechanism facilitates the installation and disassembly of the rotating rod, thereby simplifying the replacement of the grinding mesh and improving the equipment's maintenance and production efficiency.

[0011] This valve body grinding device has the advantages of being adaptable to valve bodies of different shapes and sizes and having convenient grinding parts replacement.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the grinding machine body includes a motor, a gearbox, a switch, a speed controller, and a pressure regulating device, and the rotating head is fixedly connected to the output end of the gearbox.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the motor, gearbox, switch, speed controller, and pressure regulating device are all structures that are already present in the existing grinding machine body.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by rotating the internal hexagonal nut, the screw is driven to move within the threaded ring, thereby causing the limit block to clamp or release the rotating rod, thus realizing the rapid installation and disassembly of the rotating rod.

[0017] Furthermore, the inner side of the sleeve is provided with an embedding groove that matches the limiting block, and the outer side of the rotating rod is provided with a limiting groove that matches the limiting block.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the setting of the embedding groove and the limiting groove makes the limiting block more stable when clamping the rotating rod, and prevents the rotating rod from shaking during the grinding process.

[0019] Furthermore, the two first connecting rods and the second connecting rod on the same side are arranged in a staggered manner, forming a rhomboid frame. The reinforcing ring that is rotatably connected to the third fixed block is telescopic.

[0020] The beneficial effects of adopting the above-mentioned further solution are that the diamond-shaped frame structure and the telescopic reinforcing ring enable the adaptive mechanism to flexibly change its shape, better fit the valve body surface of different shapes, and improve the polishing effect. The telescopic reinforcing ring includes multiple sub-rods combined with the main rod, and the sub-rods can slide and extend freely within the main rod.

[0021] Furthermore, the inner side of the grinding mesh is fixedly connected with a plurality of connecting plates, which are respectively fixedly connected to the second fixing block and the third fixing block, and the grinding mesh is an elastic steel wire mesh.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the connecting plate firmly connects the grinding mesh to the adaptive mechanism. The elastic steel wire mesh has good elasticity and wear resistance, which can effectively remove defects on the valve body surface during the grinding process, and has a long service life.

[0030] The adaptive mechanism 5 includes a mounting head 501, which is fixedly connected to the bottom of the rotating rod 4. Multiple first fixing blocks 502, arranged in a ring and equidistant from each other, are fixedly connected to the outer side of the mounting head 501. Two first connecting rods 503, arranged vertically and alternately, are rotatably connected inside each of the multiple first fixing blocks 502. Second fixing blocks 504 are rotatably connected to the outer sides of the first connecting rods 503 on both sides. The second fixing blocks 504 on both sides are symmetrically arranged vertically.

[0031] The grinding machine body 1 includes a motor, gearbox, switch, speed controller and pressure regulating device, and the rotating head 2 is fixedly connected to the output end of the gearbox.

[0032] The motor, gearbox, switch, speed controller, and pressure regulating device are all existing structures of the existing grinding machine body 1. The motor provides power to the rotating head 2 through the gearbox. The speed controller can adjust the speed of the rotating head 2 according to different grinding needs. The pressure regulating device can control the pressure during grinding, ensuring the grinding effect while avoiding damage to the valve body.

[0033] The fixing mechanism 3 includes a sleeve 301, which is fixedly connected to the bottom of the rotating head 2. A screw ring 302 is fixedly connected to the outside of the sleeve 301. A screw rod 303 is threadedly connected to the inside of the screw ring 302. One end of the screw rod 303 is rotatably connected to a limiting block 304 located inside the rotating rod 4. The other end of the screw rod 303 is fixedly connected to an internal hexagonal nut 305 located outside the sleeve 301.

[0034] By rotating the internal hex nut 305, the screw 303 is moved within the threaded ring 302, thereby causing the limiting block 304 to clamp or release the rotating rod 4, thus enabling the rapid installation and removal of the rotating rod 4.

[0035] The inner side of the sleeve 301 is provided with an embedding groove 7 that is adapted to the limiting block 304, and the outer side of the rotating rod 4 is provided with a limiting groove 8 that is adapted to the limiting block 304.

[0037] The two first connecting rods 503 and the second connecting rod 505 on the same side are arranged in a staggered manner, forming a rhomboid frame. The reinforcing ring 507, which is rotatably connected to the third fixing block 506, is telescopic.

[0038] The diamond-shaped frame structure and the telescopic reinforcing ring 507 enable the adaptive mechanism 5 to flexibly change shape, better fit the valve body surface of different shapes, and improve the polishing effect. The telescopic reinforcing ring 507 includes multiple sub-rods combined with the main rod, and the sub-rods can slide and extend freely within the main rod.

[0042] Step 1: Place the valve body to be polished on an external processing workbench. Based on the shape and size of the valve body, set the speed and polishing pressure of the polishing machine body 1 using the speed controller and pressure regulating device.

[0043] Step 2: Use an Allen wrench to rotate the Allen nut 305 to install the rotating rod 4 in the fixing mechanism 3. Rotate the Allen nut 305 again to make the limit block 304 clamp the rotating rod 4 to ensure that the rotating rod 4 is installed securely.

[0044] Step 3: Start the grinding machine body 1. The motor in the grinding machine body 1 drives the rotating head 2 to rotate through the gearbox. The rotating head 2 drives the fixed mechanism 3, the rotating rod 4, the adaptive mechanism 5 and the grinding mesh 6 to rotate. During the grinding process, the adaptive mechanism 5 automatically adjusts the position and shape of the grinding mesh 6 according to the shape of the valve body surface through the rotation of the first connecting rod 503 and the second connecting rod 505 and the extension and retraction of the reinforcing ring 507, so that it fits tightly against the valve body surface for grinding.
