[0022] Example 1 like Figures 1 to 2 As shown, this utility model provides an angle converter, including a panel 100, a base plate 200, a rotating mechanism, and an adjusting limit mechanism; One end of the panel 100 and one end of the base plate 200 are rotatably connected by a rotating mechanism, and the grinding machine is installed on the side of the panel 100 that is away from the base plate 200; One end of the adjusting limit mechanism is fixedly connected to the base plate 200, and the other end is slidably connected to the panel 100. The panel 100 can move along the extension direction of the adjusting limit mechanism to drive the panel 100 to rotate and adjust the angle between the axis of the panel 100 and the axis of the base plate 200. The adjusting limit mechanism can limit the panel 100.

[0023] In this embodiment, the angle converter includes a panel 100, a base plate 200, a rotating mechanism, and an adjusting limit mechanism. One end of the panel 100 and one end of the base plate 200 are rotatably connected by the rotating mechanism. The grinding machine is installed on the side of the panel 100 facing away from the base plate 200. In order to allow the panel 100 to rotate relative to the base plate 200 around the connection point, one end of the adjusting limit mechanism is fixedly connected to the base plate 200, and the other end is slidably connected to the panel 100. By moving the panel 100 along the extension direction of the adjusting limit mechanism, the angle between the axis of the panel 100 and the axis of the base plate 200 can be adjusted. After adjustment, the adjusting limit mechanism limits the panel 100, keeping it in the adjusted position. This allows the output end of the grinding machine installed on the panel 100 to be in contact with the valve seat sealing surface after adjustment. The adjustment process is clear in principle and has high adjustment accuracy. Furthermore, the limiting mechanism after adjustment prevents the grinding machine from being covered during grinding, effectively ensuring the efficiency of the work.

[0024] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjusting limit mechanism includes an adjusting bolt 101, an adjusting plate 300, and an adjusting assembly; The adjusting bolt 101 is fixed to the bottom wall of the panel 100. One end of the adjusting plate 300 is fixedly connected to the base plate 200, and the other end is slidably connected to the adjusting bolt 101. The adjusting bolt 101 can slide along the extension direction of the adjusting plate 300.

[0025] In this embodiment, an adjusting bolt 101 is fixedly provided on the bottom wall of the panel 100. In order to cooperate with the adjusting bolt 101, an adjusting plate 300 is also provided. One end of the adjusting plate 300 is fixedly connected to the base plate 200, and the other end is slidably connected to the adjusting bolt 101. That is, by sliding the adjusting bolt 101 along the extension direction of the adjusting plate 300, the panel 100 can be moved synchronously, thereby achieving the effect of adjusting the angle between the axis of the panel 100 and the axis of the base plate 200, so that the output end of the grinder installed on the panel 100 is in a state of being in contact with the valve seat sealing surface after adjustment.

[0026] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjusting plate 300 has a waist-shaped hole 301, and the adjusting bolt 101 can slide along the extension direction of the waist-shaped hole 301.

[0027] In this embodiment, the adjusting plate 300 is also provided with a waist-shaped hole 301 to facilitate the movement of the adjusting bolt 101. That is, the end of the adjusting bolt 101 can be slidably connected in the waist-shaped hole 301, that is, the adjusting bolt 101 can slide along the extension direction of the waist-shaped hole 301, thereby driving the panel 100 to move synchronously.

[0028] According to one embodiment provided by this utility model, such as Figure 1 As shown, the adjusting limit mechanism also includes a first mounting base 102 and a second mounting base 201; The first mounting base 102 is provided on the bottom wall of the panel 100. The first mounting base 102 has a first mounting hole. The inner wall surface of the first mounting hole has an internal thread. The end of the adjusting bolt 101 can be threaded into the internal thread to be fixed inside the first mounting base 102. The second mounting base 201 is located on the top wall of the base plate 200. The second mounting base 201 has a second mounting hole. The side wall of the adjusting plate 300 facing the base plate 200 has a connecting post 302, which is installed in the second mounting hole.

[0029] In this embodiment, a first mounting base 102 is installed on the bottom wall of the panel 100, and a second mounting base 201 is installed on the top wall of the base plate 200. The adjusting bolt 101 is fixed at one end in the first mounting base 102 by threaded engagement, and the other end is slidably connected in the waist-shaped hole 301. A connecting post 302 is provided on the side wall of the adjusting plate 300 facing the base plate 200. The connecting post 302 is installed in the second mounting hole. At this time, one end of the adjusting plate 300 can be fixed relative to the base plate 200. Then, the adjusting screw can be moved along the extension direction of the waist-shaped hole 301 to drive the panel 100 to move synchronously.

[0030] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjustment and limiting mechanism also includes a limiting nut 303. The end of the adjusting bolt 101 that is away from the first mounting base 102 protrudes from the waist-shaped hole 301. The limiting nut 303 and the adjusting bolt 101 are threadedly engaged to limit the panel 100.

[0031] In this embodiment, one end of the adjusting bolt 101 is fixed in the first mounting base 102 provided on the panel 100, and the other end is inserted into the oblong hole 301. The end of the adjusting bolt 101 away from the first mounting base 102 protrudes out of the oblong hole 301. That is to say, a part of the adjusting bolt 101 is located outside the oblong hole 301. This makes it easy to limit the panel 100 by threading the limiting nut 303 with the adjusting bolt 101 after adjustment, so as to ensure that the panel 100 does not move after accurate adjustment.

[0032] Preferably, the limiting nut 303 is a wing nut, which makes it easy to use.

[0033] According to one embodiment provided by this utility model, such as Figure 1 As shown, the rotating mechanism includes a first rotating assembly, a second rotating assembly, and a rotating shaft 400; The first rotating component is located on the bottom wall of the panel 100, and the second rotating component is located on the top of the base plate 200. The first rotating component and the second rotating component are rotatably connected by a rotating shaft 400 to drive the panel 100 to rotate.

[0034] In this embodiment, in order to ensure that the panel 100 can rotate relative to the base plate 200, a first rotating component is provided on the bottom wall of the panel 100 and a second rotating component is provided on the top of the base plate 200. The first rotating component and the second rotating component are driven to rotate synchronously through the rotating shaft 400, so that the panel 100 can be rotated to adjust the position of the grinder installed on the panel 100 so that the output end of the grinder can fit against the surface of the valve seat being ground.

[0035] According to one embodiment provided by this utility model, such as Figure 1 As shown, the first rotating assembly includes a first rotating seat 103, and the second rotating assembly includes a second rotating seat 202; Both the first rotating seat 103 and the second rotating seat 202 have rotating holes, and the rotating shaft 400 passes through the rotating holes of the first rotating seat 103 and the second rotating seat 202.

[0036] In this embodiment, by providing a first rotating seat 103 on the side of the panel 100 facing the base plate 200 and a second rotating seat 202 on the side of the base plate 200 facing the panel 100, and by passing a rotating shaft 400 through the rotating holes of the first rotating seat 103 and the second rotating seat 202, the panel 100 can be rotated relative to the base plate 200.

[0037] According to one embodiment provided by this utility model, such as Figure 1 As shown, there are two first rotating seats 103 and two second rotating seats 202. The two second rotating seats 202 are arranged at intervals, and the first rotating seat 103 is provided on the side of the two second rotating seats 202 that is away from each other.

[0038] In this embodiment, in order to ensure the stability of the rotation of the rotating shaft 400, two first rotating seats 103 and two second rotating seats 202 are provided. The two first rotating seats 103 are installed at intervals on the side of the panel 100 facing the bottom plate 200, and are located at the end where the panel 100 is connected to the bottom plate 200, and in the middle position, so as to reserve the position for installing the second rotating seats 202. Then, the first rotating seats 103 are respectively installed on the bottom plate 200 positions corresponding to the sides of the two second rotating seats 202 that are away from each other. By inserting the rotating shaft 400 into the rotating holes opened in the first rotating seats 103 and the second rotating seats 202, the panel 100 can rotate relative to the bottom plate 200.

[0039] According to one embodiment provided by this utility model, such as Figure 1 As shown, the panel 100 has a threaded hole 104 for connecting to a grinding machine.

[0040] In this embodiment, during use, the angle converter is placed on a fixed surface, and the panel 100 is connected and fixed to the base of the grinder by passing hexagonal bolts through the threaded hole 104. A motor is installed on the base, and a machine arm is also provided. The machine arm is perpendicular to the base, and a grinding end is connected to the end of the machine arm. The motor is connected to the grinding end for transmission. Therefore, by adjusting the base of the grinder through the panel 100, the grinding end can be moved synchronously until the grinding end is in contact with the valve seat sealing surface, and then it is limited to facilitate subsequent grinding operations.

[0041] According to one embodiment provided by this utility model, such as Figure 1 As shown, there are multiple threaded holes 104 arranged in two rows, with each row of threaded holes 104 evenly spaced along the length of the panel 100.

[0042] In this embodiment, in order to ensure the connection stability between the panel 100 and the grinding machine base, and to accommodate different types of grinding machines, two rows of threaded holes 104 are provided on the panel 100, and each row of threaded holes 104 is evenly spaced along the length of the panel 100, so as to correspond to the reserved holes of different types of grinding machine bases, thereby improving the applicability of the angle converter provided in this embodiment.
