[0020] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0021] Please see Figure 1-3 This embodiment provides a valve housing alignment device for positioning a valve housing 100. The valve housing 100 is a hollow cylinder. The top of the cylinder has serrated perforated grooves 101 spaced apart around the cylinder. The serrated perforated groove 101 with the lowest perforation height is the central perforated groove 102 of the valve housing. The valve housing alignment device includes: Rotating mechanism 1, the rotating mechanism 1 includes a rotating motor 11 and a mounting platform 12, the mounting platform 12 is connected to the output end of the rotating motor 11, and the mounting platform 12 is provided with a mounting groove 1231 for limiting the valve housing 100; A laser positioner 2 is connected to the rotary motor 11. The output end of the laser positioner 2 is positioned on the top side of the middle position of the mounting groove 1231. The laser positioner 2 has a preset height, which is higher than the minimum height of the central hollow groove 102 and lower than the minimum height of the other toothed hollow grooves 101 except for the central hollow groove 102. This is so that when the valve housing 100 is installed in the mounting groove 1231, the laser emitted by the output end of the laser positioner 2 irradiates the outer wall of the valve housing 100, or penetrates the central hollow groove 102 and irradiates the inner wall of the valve housing 100.

[0022] Based on the above structure, in practical use, the valve housing 100 can be installed in the mounting groove 1231, so that the horizontal and vertical positions of the valve housing 100 are directly positioned by the mounting groove 1231. Then, the rotating mechanism 1 is started, causing the rotating motor 11 to drive the mounting platform 12 to rotate. Therefore, the mounting groove 1231 drives the valve housing 100 to rotate. At this time, the laser positioner 2 is kept running, so that the laser positioner 2 always projects the laser onto the valve housing 100. When it has not rotated to the position of the central hollow groove 102, the laser beam... When the laser is rotated to the position of the central hollow groove 102 on the outer wall of the valve housing 100, it shines into the inner wall of the valve housing 100. Therefore, the positions of the two sides of the central hollow groove 102 can be determined by the difference between the two laser ranges and the rotation angle of the rotary motor 11. After reading both sides of the central hollow groove 102, the angle is divided by 2 and the rotary motor 11 is rotated in reverse to determine the angle of the valve housing 100. At this time, the central hollow groove 102 of the valve housing 100 is completely centered.

[0023] The output end of the aforementioned rotary motor 11 can be configured as a motor shaft assembly for transmission, which drives the corresponding component to rotate through gears or other components at the end of the motor shaft.

[0024] In this application, positioning can be achieved through laser measurement combined with a rotating mechanism 1, resulting in lower cost and a lower error rate. Specifically, in this embodiment, the valve housing has a toothed perforated groove 101. By rotating the valve housing 100, the positions of the two sides of the central perforated groove 102 can be quickly located and centered using a laser at a preset height position. The determination is mainly based on whether the laser penetrates the valve housing 100. Compared with existing visual positioning, physical positioning has higher accuracy and lower cost.

[0025] Furthermore, the valve housing 100 alignment device also includes a clamping mechanism 3, which includes a clamping cylinder 31 and a gripper 32. The mounting platform 12 includes a first mounting plate 121, a support column 122, and a second mounting plate 123. The first mounting plate 121 is connected to the output end of the rotary motor 11, and the second mounting plate 123 is connected to the first mounting plate 121 through the support column 122. The mounting groove 1231 is disposed on the top of the second mounting plate 123. The clamping cylinder 31 is disposed on the side of the first mounting plate 121 away from the rotary motor 11 and is disposed to avoid the support column 122. The gripper 31 is connected to the output end of the clamping cylinder 31, and the gripper 32 is used to clamp the valve housing 100 installed in the mounting groove 1231. In this application, the space formed by the overlap of the first mounting plate 121, the support column 122, and the second mounting plate 123 is used to install the clamping cylinder 31, and to provide the clamping claw 32 at the end of the clamping cylinder 31 with room to move. During operation, the rotary motor 11 can drive the first mounting plate 121, the support column 122, the second mounting plate 123, the mounting groove 1231, and the clamping mechanism 3 to rotate.

[0026] In practical use, after the operator places the valve housing 100 on the mounting groove 1231, the clamping cylinder 31 is activated, causing the gripper 32 to move from the first position away from the valve housing 100 to the second position that clamps the valve housing 100, so that the valve housing 100 is kept stable during rotation and the valve housing 100 is prevented from shifting or tilting.

[0027] In the above embodiments, such as Figure 1 As shown, there are multiple grippers 32, which are used to simultaneously clamp the valve housing 100 installed in the mounting groove 1231 in the second working state. The multiple grippers 32 are arranged at equal angular intervals around the center of the mounting groove 1231. In this embodiment, three grippers 32 can be used, spaced 120 degrees apart, making the clamping of the valve housing 100 more stable and balanced.

[0028] In another embodiment, the end of the gripper 32 is provided with an arc shape whose size matches the outer wall of the valve housing 100. Therefore, the valve housing 100 can be clamped more stably. Due to the contoured surface, scratches on the valve housing 100 can also be avoided, thus maintaining the yield rate.

[0029] In the above embodiments, there are multiple support columns 122, which are arranged at equal angular intervals around the center of the mounting groove 1231. Specifically, the support columns 122 in this application can be three, which are arranged at 120-degree intervals, so that the second mounting plate 123 can be effectively supported while minimizing interference with the clamping mechanism 3.

[0030] Furthermore, the valve housing alignment device also includes a positioning mechanism 4, which includes a positioning cylinder 41 and a positioning punch 42. The positioning cylinder 41 is disposed on the top of the laser positioner 2, and the positioning punch 42 is connected to the output end of the positioning cylinder 41. The end width of the positioning punch 42 matches the width of the central hollow groove 102. The positioning punch 42 has a third position and a fourth position. In the third position, the positioning punch 42 is disposed on one side of the valve housing 100 installed in the mounting groove 1231 at a horizontal distance. In the fourth position, the end of the positioning punch 42 passes through the central hollow groove 102. Specifically, after the valve housing 100 is positioned by the laser positioner 2 and rotated to the positioning angle, the final step is to physically interfere directly with the valve housing 100 with the positioning punch 42, which has an absolutely precise angle, so that its position is maximized and accurately positioned. After the positioning is completed, the positioning punch 42 is withdrawn.
