Description

Technical Field

[0001] This application relates to the field of valve body processing technology, and in particular to a grinding device for valve body forging production. Background Technology

[0002] With the development of valve body forging processing technology, the requirements for grinding precision and efficiency of valve body surfaces and connecting parts are increasing. Especially in the production of irregularly shaped valve body forgings, their complex structure and irregular gaps at pipe joints make it difficult for traditional grinding methods to achieve uniform, efficient, and safe processing. Therefore, the industry has successively proposed various specialized grinding devices for valve body forgings to improve processing quality and automation levels.

[0003] A search revealed a grinding device for irregularly shaped valve body forgings (Chinese Patent Publication No. CN119526192B). This device includes a reciprocating horizontally rotating turntable, a clamping mechanism, a dustproof mechanism, and a grinding mechanism. The clamping mechanism, mounted on the turntable, is used to fix the irregularly shaped valve body. The dustproof mechanism has a retractable dust cover to seal and protect the valve opening, preventing grinding dust from entering. The grinding mechanism uses an adaptive grinding roller to grind the gaps at the valve opening connection on the side wall of the valve body. This solution achieves multi-angle processing through turntable rotation, improving adaptability to complex structures.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing grinding mechanisms rely solely on the adaptive adjustment of the grinding rollers, lacking precise control over grinding depth and pressure. When faced with valve body forgings of different materials or with significant size differences, uneven grinding or over-grinding is likely to occur. Furthermore, the entire device has a fixed structure, and the relative position between the platform and the grinding components is not adjustable, making it impossible to flexibly adjust the working space according to the size of the workpiece, resulting in poor versatility.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a grinding apparatus for valve body forging production. For example... Figure 1As shown, the basic frame of the entire device consists of a T-shaped frame 1, whose bottom is fixed to the ground by supports, and whose top is welded to a column 2. The column 2 is vertically installed on the top of the T-shaped frame 1, providing support for the first horizontal square steel 3 and ensuring the stability of the overall structure. The first horizontal square steel 3 is horizontally welded to the top of the column 2, and a first inner square steel 51 is inserted inside it. The first electric push rod 52 enables telescopic adjustment, thus providing an adjustable support structure for the platform 5. The first inner square steel 51 is integrally connected to the corner of the platform 5 near the first horizontal square steel 3. The first inner square steel 51 is inserted into the first horizontal square steel 3, and the first electric push rod 52 is bolted to the end of the first horizontal square steel 3 away from the platform 5. The output end of the first electric push rod 52 is bolted to the first inner square steel 51 to enable the platform 5 to move horizontally along the first horizontal square steel 3. This design allows the platform 5 to be adjusted forward and backward according to the workpiece size, accommodating valve body forgings of different lengths.

[0031] Please see Figure 3 A second horizontal square steel 4 is welded to the top of the first horizontal square steel 3. The second horizontal square steel 4 extends horizontally and provides installation space for the grinding assembly 6. A second inner square steel 41 is inserted into the end of the second horizontal square steel 4 near the platform 5. A triangular plate 42 is provided on the side of the second inner square steel 41 near the platform 5. The middle of the triangular plate 42 is rotatably connected to the second inner square steel 41 through a rotating shaft, and an arc-shaped adjustment groove 43 is formed along the rotating shaft. The arc-shaped adjustment groove 43 is tightened and fixed to the second inner square steel 41 by a tightening bolt, thereby realizing the angle adjustment of the grinding assembly 6. This design allows the grinding assembly 6 to be flexibly adjusted according to the tilt angle of the workpiece surface, ensuring that the grinding belt 601 and the workpiece surface always maintain the best contact state.

[0032] Please see Figure 4 The design of the arc-shaped adjustment groove 43 allows the triangular plate 42 to rotate within a certain range. The angle can be fixed by tightening the bolts. The operation is simple and the precision is high.

[0033] Please see Figure 4 , 5The grinding assembly 6 includes a grinding belt 601, a first pulley 61, a second pulley 62, a tension roller 64, and a third pulley 63. The grinding belt 601 is driven at both ends by the first pulley 61 and the second pulley 62, respectively. Both the first pulley 61 and the second pulley 62 are rotatably connected to the top and bottom of the triangular plate 42 via bearings. The tension roller 64 and the third pulley 63 are respectively installed at the inner top and bottom of the end of the grinding belt 601 furthest from the platform 5. The support of the tension roller 64 is mounted on the top of the second horizontal square steel 4 and is used to adjust the tension of the grinding belt 601. The position of the tension roller 64 can be finely adjusted using the adjusting bolts on the support, ensuring that the grinding belt 601 maintains proper tension during operation and preventing slippage or wear due to loosening. The shaft of the third pulley 63 is rotatably connected to a transmission rod 65 via bearings. The transmission rod 65 is rotatably mounted on one side of the column 2 via a bearing seat, thereby transmitting power from the drive assembly 7 to the grinding assembly 6.

[0034] Please see Figure 1 , 5 The drive assembly 7 includes a drive motor 71, a gearbox 72, a first synchronous pulley 73, and a second synchronous pulley 74. The drive motor 71 is bolted to the top of the T-shaped frame 1. The gearbox 72 connects the output end of the drive motor 71 to the first synchronous pulley 73. The first synchronous pulley 73 is connected to the second synchronous pulley 74 via a synchronous belt. The second synchronous pulley 74 is mounted on the transmission rod 65, thereby achieving efficient power transmission from the drive motor 71 to the grinding assembly 6. The design of the gearbox 72 allows the output speed of the drive motor 71 to be adjusted according to actual processing requirements, thereby improving grinding efficiency and precision. For example, when processing valve body forgings with high hardness, the speed can be reduced to increase torque, ensuring a smooth and uniform grinding process; while when processing softer materials, the speed can be appropriately increased to improve processing efficiency.

[0035] The implementation principle of a grinding device for valve body forging production according to an embodiment of this application is as follows: The valve body forging to be processed is placed on platform 5. According to the size and shape of the workpiece, the relative position between platform 5 and grinding assembly 6 is adjusted by first electric push rod 52. The extension and retraction of first electric push rod 52 causes first inner square steel 51 to slide along first horizontal square steel 3, thereby realizing the front and back adjustment of platform 5. According to the tilt angle of workpiece surface, the angle of triangle plate 42 is adjusted by tightening bolts to keep grinding belt 601 in optimal contact with workpiece surface. Then, drive motor 71 is started. Drive motor 71 transmits power to first synchronous pulley 73 through gearbox 72. First synchronous pulley 73 drives second synchronous pulley 74 to rotate through synchronous belt. Second synchronous pulley 74 transmits power to third pulley 63 through transmission rod 65, thereby driving grinding belt 601 to rotate. Tension roller 64 adjusts the tension of grinding belt 601 to ensure efficient and uniform grinding process. Throughout the processing, the user can adjust the position of platform 5 and the angle of grinding component 6 at any time according to actual needs to adapt to valve body forgings of different sizes and shapes.

[0036] Furthermore, the first horizontal square steel 3 and the second horizontal square steel 4 provide telescopic adjustment pull-out structures for the platform 5 and the grinding component 6, respectively. Combined with the adjustment mechanism of the first electric push rod 52 and the triangular plate 42, flexible adjustment between the platform 5 and the grinding component 6 is realized. This is suitable for grinding various types of valve body forgings. Through the adjustment mechanism of the first electric push rod 52 and the triangular plate 42, precise control of grinding depth and pressure is achieved, avoiding uneven grinding or over-grinding caused by material or size differences in traditional grinding methods.

[0037] Furthermore, the grinding assembly 6 employs a grinding belt 601 in conjunction with a pulley and tension roller 64 to ensure efficient and uniform grinding. The drive assembly 7 transmits power via a gearbox 72 and a synchronous pulley, improving the automation level of the device. The overall structure is compact and rationally designed, with components securely installed through welding, bolting, and other methods, ensuring the stability and durability of the device. In particular, the telescopic and angle adjustment mechanisms make operation more convenient, enhancing the versatility and practicality of the device.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
