For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Reference Figures 1-3 According to an embodiment of the present invention, a high-efficiency valve ball polishing machine includes a base 11, on which a support component and a polishing component are provided. The support component is used to support the valve ball, and the polishing component is used to polish the supported valve ball.

[0021] Specifically, the support assembly includes a lifting platform 21 that is slidably connected to the base 11, and the base 11 is equipped with a lifting cylinder 22 for controlling the lifting platform 21 to move up and down. The side of the lifting platform 21 is equipped with a support rod 23, and a valve ball can be fitted over the support rod 23.

[0022] The polishing assembly includes a cover frame 41 mounted on the base 11, a first rotating shaft rotatably connected inside the cover frame 41, and a polishing motor 42 for driving the first rotating shaft to rotate on the cover frame 41. A polishing part is mounted on the first rotating shaft. In addition, it also includes a speed limiting assembly for controlling the rotation speed of the valve ball sleeved on the support rod 23.

[0023] During polishing, the operator can insert the valve ball through the first rotating shaft, and then control the lifting platform 21 to descend through the lifting cylinder 22 until the valve ball outside the support rod 23 contacts the polishing part. At the same time, the speed limiting component can limit the rotation speed of the valve ball outside the support rod 23 and create a speed difference between it and the polishing part so that the valve ball can be polished by the polishing part.

[0024] like Figure 1 As shown, the polishing part is a polishing and drawing wheel 43, and the polishing and drawing wheel 43 is provided with multiple wheels evenly distributed at front and back, and the outer curved surface of the polishing and drawing wheel 43 is provided with annular grooves.

[0025] The polishing component may also include a fixed wheel fixed on the first rotating shaft and multiple sandpapers arranged at equal angles outside the fixed wheel. The outer end of the sandpaper may also be provided with an annular groove, which can also perform polishing work.

[0026] The groove surface of the annular groove can fit against the curved surface of the valve ball. Through the setting of the annular groove, the polishing wheel 43 can perform a complete polishing of the outer curved surface of the valve ball, improve the polishing effect, and also play a positioning role for the valve ball, preventing the valve ball located on the support rod 23 from shifting back and forth.

[0027] The speed limiter includes a mounting bracket 51 mounted on the base 11, a second rotating shaft is rotatably connected inside the mounting bracket 51, and a speed limiting motor 52 for driving the second rotating shaft to rotate is mounted on the mounting bracket 51. A rubber sleeve 53 is mounted on the second rotating shaft. The rubber sleeve 53 and the polishing and wire drawing wheel 43 are located on the left and right sides of the support rod 23, respectively.

[0028] The speed-limiting motor 52 can drive the rubber sleeve 53 to rotate at a speed less than that of the polishing and wire drawing wheel 43. When the lifting platform 21 descends and the valve ball outside the support rod 23 contacts the polishing and wire drawing wheel 43 for polishing, the valve ball will stick to the rubber sleeve 53, and the friction between the valve ball and the rubber sleeve 53 is large. This causes the valve ball to be driven to rotate by the rubber sleeve 53, and thus there is a speed difference between it and the polishing and wire drawing wheel 43, so as to facilitate polishing.

[0029] In the second embodiment of the high-efficiency valve ball polishing machine, in order to adapt the high-efficiency valve ball polishing machine to valve balls of different specifications, the mounting bracket 51 and the cover frame 41 are both designed to slide left and right on the base 11. The left and right sides of the base 11 are respectively equipped with positioning cylinders 61 for controlling the left and right positions of the mounting bracket 51 and the cover frame 41. In this embodiment, the support rod 23 and the polishing wheel 43 can also be replaced to change the diameter of the support rod 23 and the size of the polishing wheel 43. The method of fixing and disassembling the support rod 23 is a conventional setting in the prior art and will not be described in detail here.

[0030] When the diameter of the valve ball changes, the operator selects and installs the support rod 23 and the polishing wheel 43 that are compatible with the inner diameter of the valve ball. Then, the operator adjusts the left and right positions of the 41 and the mounting bracket 51 according to the outer diameter of the valve ball and the positioning cylinder 61 so that they can be refitted to the size of the valve ball.

[0031] In a third embodiment of the high-efficiency valve ball polishing machine, in order to enable the valve ball to be positioned when it is sleeved on the support rod 23 without relying entirely on the observation of the operator, the curved surface of the support rod 23 is provided with a plurality of positioning plates 24 distributed at equal distances in the front and back, and also includes a telescopic mechanism for controlling the inner and outer positions of the positioning plates 24.

[0032] In this third embodiment, the telescopic mechanism includes a slot 25 disposed in the support rod 23, a push plate 26 is slidably connected in the slot 25, and the push plate 26 is connected to the bottom surface of the slot 25 by a spring. Multiple triangular plates 27 are distributed at equal distances on the side of the push plate 26, and the positioning plate 24 is slidably connected to the inclined surface in each of the triangular plates 27 in sequence.

[0033] Whenever the operator presses the push plate 26, the triangular plate 27 pushes the positioning plate 24 outward, causing the positioning plate 24 to extend to the upper side of the support rod 23 and position the valve ball. When the push plate 26 is released, the push plate 26 moves forward under the action of the first spring, and the positioning plate 24 retracts inward to avoid contact with the polishing and brushing wheel 43 and to avoid interfering with the operator's handling of the valve ball.

[0034] Furthermore, the positioning plate 24 includes a slide 71 and a telescopic plate 72 that is slidably connected to the slide 71. The telescopic plate 72 is also connected to the slide 71 by a second spring, and the slide 71 is slidably connected to the inclined surface inside the triangular plate 27.

[0035] With the above settings, when the user presses the push plate 26, only the telescopic plate 72 can extend beyond the support rod 23.

[0036] Specific valve ball polishing process: First, the worker places the valve balls, matching the number of polishing and wire drawing wheels 43, onto the support rod 23. Then, the worker presses the push plate 26 inward, causing the positioning plate 24 to protrude outward. Specifically, the telescopic plate 72 inside the positioning plate 24 pops out, allowing the worker to push each valve ball backward against the telescopic plate 72 to complete the valve ball positioning. Afterward, the worker can release the push plate 26, allowing the positioning plate 24 to retract inward.

[0037] During the above process, even if the valve ball is outside the positioning plate 24, the telescopic plate 72 can retract to avoid interfering with the push plate 26 being pressed inward. The telescopic plate 27, which is in the retracted state, can pop out again after the valve ball is adjusted and play a positioning role.

[0038] After the valve ball is installed, the operator controls the lifting cylinder 22 to move the lifting platform 21 downward until the valve ball outside the support rod 23 simultaneously contacts the polishing wheel 43 and the rubber sleeve 53. At this time, the valve ball will be rotated by the rubber sleeve 53 and polished by the polishing wheel 43. During this process, the support rod 23 remains stationary. After polishing is completed, the operator can raise the lifting platform 21 and remove the valve ball.

[0039] Of course, the above process can also be that after the lifting platform 21 is lowered into place, the mounting frame 51 and the cover frame 41 are brought close to each other and polished.

[0040] It should be noted that if there is a process requirement for polishing the inner hole of the valve ball, the process of polishing the outer curved surface of the valve ball using the aforementioned high-efficiency valve ball polishing machine should be performed before the process of polishing the inner hole of the valve ball. The outer diameter of the support rod 23 is slightly smaller than the inner diameter of the valve ball, so that the valve ball can rotate relative to the support rod 23 and the valve ball can be disassembled and assembled without being too stuck. The curved surface of the support rod 23 can also be provided with a vertically insertable pin (not shown in the figure). During polishing, the pin can prevent the valve ball from being thrown out in a very small probability. This is a redundant safety measure. When it is necessary to disassemble or assemble the valve ball, the pin needs to be removed.

[0041] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
