Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing, specifically to a deburring machine for valve manufacturing. Background Technology

[0002] Valves are widely used in many fields such as industrial production and building water supply and drainage, and their performance directly affects the safety and stability of the entire system. During the valve manufacturing process, whether through casting, forging, or machining, burrs are inevitably generated on the valve's surface, edges, and internal passages. These burrs not only affect the valve's appearance but, more importantly, can have a serious negative impact on key performance indicators such as sealing performance and fluid flow properties.

[0003] Existing grinding mechanisms are relatively simple for grinding the outer surface of valves when dealing with burrs, but they lack specialized grinding mechanisms when it comes to burr treatment inside the valve passage. This results in differences in burr treatment among valves processed in the same batch, affecting the sealing performance and fluid flow of subsequent valves, which is a shortcoming.

[0005] To address the technical problems existing in the background art, this utility model proposes a burr grinding machine for valve manufacturing, which features convenient grinding of the inside of the valve channel and ensures the yield of valves in the same batch after grinding.

[0010] Preferably, the bracket has an "I" structure, and the two brackets support the valve body to be processed.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-3 As shown, the present invention proposes a burr grinding machine for valve manufacturing, including a base 1, a support mechanism including brackets 21 symmetrically installed on the base 1, a platform 3 installed on the upper part of the brackets 21, and an inner support member 23 that cooperates with the valve being clamped inside the platform 3;

[0025] A platform 3 is provided on one side of the bracket 21. The drive mechanism includes a motor 41 mounted on the platform 3. The output end of the motor 41 is connected to a transmission device 42. The transmission device 42 has a built-in rotatable rotating disk 43. A first cylinder 44 is mounted on the rotating disk 43. A movable first piston rod 45 is mounted on the output end of the first cylinder 44. A support 46 is mounted on the other end of the first piston rod 45.

[0026] The polishing mechanism includes a fill light 51, a distance sensor 52, and a second cylinder 53 mounted side by side on 46. The output end of the second cylinder 53 is equipped with a movable second piston rod 54, and the other end of the second piston rod 54 is connected to a protruding polishing part 55.

[0027] It should be noted that: the bracket 21 has an "I" structure, and the two brackets 21 support the valve body to be processed. The middle part of the valve has a raised structure, and the two ends have pipe structures. When grinding the valve channel inside the valve body, the clamping and supporting of the pipes at both ends can prevent the valve body from loosening during the grinding process. The inner support 23 is a support structure made according to the specifications of the valve body to be processed, which can effectively prevent it from shaking due to vibration during the grinding process and causing damage to the valve channel.

[0028] In this embodiment, the support mechanism is used to support the valve body to be processed. After the valve body is clamped, the drive mechanism works, and the first cylinder 44 drives the support 46 connected to the first piston rod 45 to move into the valve body channel. At this time, the grinding mechanism works, and the distance between the grinding part 55 and the inner wall of the valve channel is monitored by the distance sensor 52. The movement distance of the grinding part 55 is controlled. The grinding part 55 moves synchronously with the second piston rod 54, and its outer edge is always attached to the valve cavity channel of the valve body to be processed. At this time, the motor 41 drives the rotating disk 43 in the transmission device 42 to rotate, which in turn drives the first cylinder 44 and the grinding mechanism to rotate as a whole. The grinding part 55 continuously grinds the valve channel. When the middle of the valve body is ground, the installation direction of the valve body at the support mechanism can be changed to grind the other end face.

[0029] It is understandable that the first piston rod 45 makes a linear displacement along the valve body channel to be processed, and the first piston rod 45 and the valve body channel to be processed are on the same axis, that is, the first piston rod 45 and the grinding mechanism connected thereto can move freely in the valve channel.

[0030] To facilitate the rotation of the first cylinder 44, a gap is left between the first cylinder 44 and the platform 3. The first cylinder 44 rotates in a circle with the rotating disk 43. The transmission device is a gear set, and the rotating disk 43 is rotated by the meshing of the large and small gears.

[0031] To further enable distance detection and observation within the valve channel, the supplementary light 51, the distance sensor 52, and the second cylinder 53 are connected to perform illumination, distance measurement, and position adjustment of the grinding component 55 within the valve channel.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
