[0012] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0013] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0014] Example 1:

[0015] This embodiment provides a valve ball surface processing device, including a worktable 1, comprising: The first grinding device includes a grinding wheel 2, a first driving member 3 and a first moving mechanism 4. The grinding wheel 2 is mounted on the output end of the first driving member 3. The first driving member 3 is mounted on the first moving mechanism 4 to control the grinding wheel 2 to rotate. The first moving mechanism 4 is mounted on the worktable 1 to control the driving member to move along the Y direction. The second grinding device includes a fixed frame 5, a grinding belt 6 and a tensioning mechanism 7. The fixed frame 5 is installed on the worktable 1, and the tensioning mechanism 7 is installed on the fixed frame 5 to keep the grinding belt 6 in a taut state. The valve ball positioning device includes a positioning element 8, a second driving element 9, and a second moving mechanism 10. The positioning element 8 is connected to the output end of the second driving element 9. The second driving element 9 is mounted on the second moving mechanism 10 to control the positioning element 8 to rotate. The second moving mechanism 10 is mounted on the worktable 1 to control the second driving element 9 to move along the X direction. The valve ball to be processed is sleeved on the positioning part 8 and located between the abrasive belt 6 and the grinding wheel 2. The abrasive belt 6 and the grinding wheel 2 are in contact with the surface of the valve ball.

[0016] In this technical solution, when the valve ball surface processing equipment is working, the positioning component 8 is first moved to a designated position by controlling and adjusting the second moving mechanism 10. Then, the valve ball to be processed is installed on the positioning component 8, ensuring that the valve ball and the surface of the abrasive belt 6 are in close contact. Next, the grinding wheel 2 is moved to a designated position by controlling and adjusting the first moving mechanism 4, ensuring that the grinding surface of the grinding wheel 2 also contacts the surface of the valve ball. Finally, the first driving component 3 controls the grinding wheel 2 to rotate, and the positioning component 8 is controlled to rotate by the second driving component 9. Both the first driving component 3 and the second driving component 9 can be drive motors. The rotation of the positioning component 8 causes the valve ball to rotate, and the valve ball and the abrasive belt 6 make relative rotational contact. At the same time, the grinding wheel 2 also makes rotational contact with the valve ball, achieving dual grinding processing of the valve ball surface. This eliminates the need for manual hand-held abrasive tools to grind the valve ball, reducing labor input and effectively improving production efficiency.

[0017] Furthermore, the positioning component 8 includes a connecting seat 11, a fixing rod 12, and a locking component 13. The connecting seat 11 is installed on the output end of the second driving component 9 and a fixing groove is provided on the connecting seat 11; the fixing rod 12 is inclined and is inserted into the fixing groove. The locking element 13 is installed on the connecting seat 11 and can be a screw, used to lock the fixing rod 12 into the fixing groove.

[0018] In the above structural design, the connecting seat 11 is composed of two frustum-shaped fixing blocks. The two frustum-shaped fixing blocks are integrally connected together on their periphery. One fixing block is installed on the output shaft of the drive motor, and the other fixing block has a fixing groove at its end, so that the fixing groove is inclined relative to the output shaft of the drive motor. One end of the positioning member 8 is inserted into the fixing groove and locked on the fixing block by setting fasteners. With this structural design, when the drive motor controls the connecting seat 11 to rotate, it can drive the fixing rod 12 to move along the conical surface, thereby driving the valve ball on the positioning rod to deflect, so that various parts of the valve ball surface can fully contact and rub with the grinding wheel 2 and the abrasive belt 6, thereby improving the grinding effect.

[0019] Furthermore, both the first moving mechanism 4 and the second moving mechanism 10 are lead screw modules. In this technical solution, both the first moving mechanism 4 and the second moving mechanism 10 can be lead screw modules controlled by a rotary handle. The first driving component 3 and the second driving component 9 are moved by manually operating the rotary handle to rotate the lead screw, which is simple to operate.

[0020] Furthermore, a "V"-shaped grinding groove 14 is provided on the circumference of the grinding wheel 2. Through this structural design, by providing a "V"-shaped grinding groove 14 on the grinding wheel 2, when the first moving mechanism 4 controls the grinding wheel 2 to move along the Y direction and approach the abrasive belt 6, the valve ball can fall into the grinding groove 14. The grinding groove 14 is used to limit the valve ball along the X direction, preventing the valve ball from detaching during the grinding process, effectively improving reliability.

[0021] Example 2:

[0022] This embodiment provides a valve ball surface processing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] Furthermore, tensioning mechanism 7 includes: An adjustment component is mounted on the fixed frame 5, which is movable along the Z-direction; Positioning roller 15 is mounted on the fixed frame 5 and is arranged along the X direction; A number of tension rollers 16 are mounted on a fixed frame 5; The positioning roller 15 has a positioning groove 17 on its circumference, and the abrasive belt 6 passes through the positioning groove 17.

[0024] Furthermore, the mounting bracket 5 is provided with a sliding groove 18, and the adjustment assembly includes: A fixed base 19 is provided with a slider, which is movable in the slide groove 18 along the Z direction; Adjusting roller 20 is mounted on fixed base 19 and is arranged along the X direction; Adjusting screw 21 is rotatably mounted on fixed frame 5 and threadedly connected to slider; The drive handle 22 is connected to the adjusting screw 21 and is used to control the rotation of the adjusting screw 21.

[0025] In this technical solution, by setting an adjusting roller 20, a positioning roller 15, and several tensioning rollers 16 arranged along the X-direction on the fixed frame 5, the abrasive belt 6 is sequentially routed through the adjusting roller 20, the positioning roller 15, and the tensioning rollers 16, with the abrasive belt 6 located within the positioning groove 17. The positioning groove 17 can limit the abrasive belt 6 along the X-direction, ensuring the stability of the abrasive belt 6 during operation. Depending on the length of the abrasive belt 6, the operator can control the adjusting roller 20 to move and adjust its position along the Z-direction by rotating the drive handle 22, keeping the abrasive belt 6 in a tensioned state.

[0026] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
