[0019] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present utility model provides a valve positioning ring automatic grooving machine, as Figures 1-3As shown in the figure, the automatic grooving machine for valve positioning rings includes: a support plate 1, on which two strip-shaped holes are symmetrically arranged about the center; two electric push rods 2 fixedly installed on the top of the support plate 1, and a top plate 3 is fixedly installed between the output rods of the two electric push rods 2; a clamping mechanism assembled on the support plate 1 for fixing the valve positioning ring; and a grooving mechanism installed on the top plate 3 for processing the valve positioning ring.

[0021] In this embodiment, when using this device to process the valve positioning ring, first place the valve positioning ring to be processed at the central position of the support plate 1, and then use the clamping mechanism to clamp and fix it. After fixing, it is necessary to adjust the distance between the milling cutter 15 and the brush 16 in the grooving mechanism according to the size of the valve positioning ring, so as to facilitate the grooving process of valve positioning rings of different specifications by this device. When the milling cutter 15 and the brush 16 are adjusted to the corresponding positions, the grooving mechanism can be used to process the valve positioning ring. During the grooving process, it is also necessary to start the electric push rod 2 to drive the top plate 3 to move vertically. The top plate 3 will drive the grooving mechanism to move vertically, so that the milling cutter 15 and the brush 16 in the grooving mechanism can contact the valve positioning ring, enabling the milling cutter 15 to cut out a groove with a corresponding depth according to requirements, and enabling the brush 16 to clean the debris accumulated on the valve positioning ring, with good use effect.

[0022] In a further preferred embodiment of the present invention, the clamping mechanism includes: a double-shaft motor 4 fixedly installed at the center of the bottom of the support plate 1, and horizontal lead screws 5 are fixedly installed on both output shafts of the double-shaft motor 4; two L-shaped brackets 6 respectively threadedly installed on the two lead screws 5, and the two L-shaped brackets 6 are respectively slidably connected to the inner walls of the two strip-shaped holes, and the horizontal sections of the two L-shaped brackets face each other; and two clamping plates 7 respectively welded to the horizontal sections of the two L-shaped brackets 6.

[0023] In this embodiment, the clamping mechanism is used to fix the valve positioning ring. When in use, start the double-shaft motor 4, and the double-shaft motor 4 will drive the two lead screws 5 to rotate. The two lead screws 5 will drive the two L-shaped brackets 6 to move away from or close to each other. When the two L-shaped brackets 6 move close to each other, the two clamping plates 7 can slowly approach the valve fixing ring placed on the support plate 1 until the two clamping plates 7 tightly clamp the valve positioning ring, thus completing the fixing work of the valve positioning ring.

[0024] In a further preferred embodiment of the present utility model, the grooving mechanism includes: a first servo motor 8 fixedly installed at the center of the bottom of the top plate 3, a cross plate 9 fixedly installed on the output shaft of the first servo motor 8, and both ends of the cross plate 9 extending downward and provided with sliding grooves; a bidirectional screw 10 rotatably installed in the sliding grooves, with one end of the bidirectional screw 10 extending outside the cross plate 9; a second servo motor 11 fixedly installed on one side of the cross plate 9, and the output shaft of the second servo motor 11 fixedly connected to one end of the bidirectional screw 10; two sliders 12 threadedly installed on two threaded sections of the bidirectional screw 10, and a third servo motor 13 and a support rod 14 are respectively fixedly installed at the bottoms of the two sliders 12; a milling cutter 15 fixedly installed on the output shaft of the third servo motor 13; and a brush 16 fixedly installed at the bottom end of the support rod 14.

[0025] In this embodiment, the grooving mechanism is used to process the valve positioning ring. Before grooving, it is necessary to first start the second servo motor 11. The second servo motor 11 will drive the bidirectional screw 10 to rotate, and the bidirectional screw 10 will drive the two sliders 12 to approach or move away from each other, thereby adjusting the distance between the milling cutter 15 and the brush 16. Since the position of the milling cutter 15 can be adjusted, the device can perform grooving on valve positioning rings of different sizes. After the adjustment is completed, grooving work can be carried out. During grooving, it is necessary to start the first servo motor 8. The first servo motor 8 will drive the cross plate 9 to rotate, first rotate one full circle forward, and then rotate one full circle backward, so that the milling cutter 15 and the brush 16 can rotate continuously. At this time, it is also necessary to start the third servo motor 13. The third servo motor 13 will drive the milling cutter 15 to rotate. In this way, as long as multiple electric push rods 2 are started to drive the top plate 3 to move vertically, the milling cutter 15 can perform grooving work on the valve positioning ring below, and can open a groove with a corresponding depth according to requirements. At the same time, the brush 16 can also clean the debris accumulated on the valve positioning ring, and the use effect is better.

[0026] In a further preferred embodiment of the present utility model, anti-slip pads are fixedly installed on both of the two clamping plates 7, and both of the two clamping plates 7 are arranged in an arc shape.

[0027] In this embodiment, by using the two anti-slip pads, the friction between the two clamping plates 7 and the valve positioning ring can be increased, and the fixing effect of the two clamping plates 7 on the valve positioning ring can be effectively improved.

[0028] In a further preferred embodiment of the present utility model, an annular groove is opened at the bottom of the top plate 3, a plurality of steel balls 18 are slidably installed on the inner wall of the annular groove, a limiting rod 17 is fixedly installed at the bottom of each of the plurality of steel balls 18, and the bottom ends of the plurality of limiting rods 17 are fixedly connected to the top of the cross plate 9.

[0029] In this embodiment, through the cooperation of the annular groove, multiple steel balls 18 and multiple limiting rods 17, a good supporting effect can be achieved on the cross plate 9, and the supporting force of the first servo motor 8 on the cross plate 9 can be reduced. When the first servo motor 8 drives the cross plate 9 to rotate, the cross plate 9 will drive multiple limiting rods 17 to rotate, and multiple limiting rods 17 will drive multiple steel balls 18 to slide in the annular groove.

[0030] In a further preferred embodiment of the present utility model, two supporting blocks are fixedly installed at the bottom of the supporting plate 1. The two supporting blocks are respectively rotatably connected to the two lead screws 5. A protective shell is fixedly installed at the bottom of the supporting plate 1. The protective shell is located outside the dual-axis motor 4, and the protective shell is rotatably connected to the two lead screws 5.

[0031] In this embodiment, through the use of the two supporting blocks, a good supporting effect can be achieved on the two lead screws 5, enabling the two lead screws 5 to maintain good stability during operation. Through the protective shell, an effective protective effect can be achieved on the dual-axis motor 4, preventing moisture and dust from eroding the dual-axis motor 4.

[0032] In a further preferred embodiment of the present utility model, sliding rods 19 are fixedly installed on the inner walls of the two strip-shaped holes. The two sliding rods 19 are respectively slidably connected to the two brackets 6.

[0033] In this embodiment, through the use of the two sliding rods 19, a supporting effect can be achieved on the two brackets 6, strengthening the stability of the two brackets 6 during horizontal movement.

[0034] In summary, compared with the related art, through the use of the clamping mechanism in this solution, it is convenient for the staff to stably fix the valve positioning ring to be processed on the supporting plate 1. It can be used to fix valve positioning rings of various specifications, and the fixing effect is good. Through multiple electric push rods 2, the top plate 3 can be driven to move vertically, enabling the top plate 3 to drive the operating grooving mechanism to perform grooving and cleaning processes on the lower valve positioning ring, and corresponding-depth grooves can be opened according to requirements. Since the distance between the milling cutter 15 and the brush 16 in the grooving mechanism can be adjusted, the device can perform grooving processes on valve positioning rings of different specifications, and the versatility is good.
