[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0035] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "horizontal", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0036] On the assembly line of the valve body, when the valve body is assembled, after the valve stem of the semi-finished valve body is assembled, the valve stem connecting holes on the valve stem are not oriented in a uniform direction. In the subsequent process, the handle needs to be installed on the valve stem. Therefore, before this, the valve stem needs to be rotated and the valve stem connecting holes need to be adjusted to a uniform direction to facilitate assembly line assembly. However, the existing valve stem connecting hole adjustment is generally performed manually, which is time-consuming and labor-intensive. In order to solve this problem, the utility model provides a valve body hole positioning device.

[0037] like Figures 1-2 As shown, the valve body hole positioning device described in this embodiment includes a valve body hole positioning component 1 and a valve body hole position adjustment component 2 which are arranged on two adjacent workstations on the valve body assembly line. The valve body hole positioning component 1 is located at the first workstation upstream, and the valve body hole position adjustment component 2 is located at the second workstation downstream.

[0038] During the valve body assembly process, the semi-finished valve body (such as Figure 3 As shown in the figure, the semi-finished valve body flows on the valve body assembly line. When the semi-finished valve body flows to the first station, the valve body hole positioning component 1 positions the hole to be positioned on the semi-finished valve body, and determines the angle between the axis of the hole to be positioned and the preset first reference plane. Then the semi-finished valve body flows to the second station, and the valve body hole position adjustment component 2 rotates the rod where the hole to be positioned on the semi-finished valve body is located according to the angle, so that the axis of the hole to be positioned is rotated to the second reference plane parallel to the first reference plane, thereby completing the adjustment of the direction of the hole to be positioned.

[0039] Specifically, if Figure 4 As shown, the valve body hole positioning assembly 1 includes:

[0040] The laser emitting device 101 and the laser receiving device 102 are both arranged on a first plane, which refers to the plane of the cross section of the rod member where the hole to be positioned on the semi-finished valve body in the first station is located. The axis of the hole to be positioned on the semi-finished valve body in the first station is located in the first plane. The laser emitting device 101 and the laser receiving device 102 are arranged on opposite sides of the rod member where the hole to be positioned is located along the radial direction of the rod member;

[0041] The first rotating mechanism, the laser emitting device 101 and the laser receiving device 102 are arranged on the first rotating mechanism, the first rotating mechanism is used to drive the laser emitting device 101 and the laser receiving device 102 to rotate around the axis of the rod where the hole to be positioned is located, and record the angle of rotation of the first rotating mechanism from the initial to the current when the laser receiving device 102 receives the laser.

[0042] In the above embodiment, the vertical plane where the laser emitting device 101 and the laser receiving device 102 are initially located can be set as a first reference plane, and then the laser emitting device 101 and the laser receiving device 102 are turned on. If the laser emitting device 101 and the laser receiving device 102 are not at the two ends of the hole to be positioned, the laser emitted by the laser emitting device 101 will be blocked by the rod where the hole to be positioned is located. When the laser receiving device 102 receives the laser, it means that the laser emitting device 101 and the laser receiving device 102 are just at the two ends of the hole to be positioned. Based on the reception status of the laser receiving device 102 for the laser, the first rotating mechanism records the angle of the first rotating mechanism from the initial to the current rotation when the laser receiving device 102 receives the laser, and the angle between the axis of the hole to be positioned and the first reference plane can be obtained.

[0043] Specifically, if Figure 5 As shown, the valve body hole position adjustment component 2 includes:

[0044] The needle 201 is arranged on a second plane, which refers to the plane of the cross section of the rod member where the hole to be positioned on the semi-finished valve body in the second station is located. The axis of the hole to be positioned on the semi-finished valve body in the second station is located in the second plane. The needle 201 is arranged along the radial direction of the rod member where the hole to be positioned is located;

[0045] A telescopic mechanism, on which the needle 201 is disposed, is used to drive the needle 201 to move radially along the rod where the hole to be positioned is located, thereby allowing the needle 201 to penetrate into or exit from the hole to be positioned;

[0046] The second rotating mechanism, the telescopic mechanism is provided on the second rotating mechanism, and the second rotating mechanism is used to drive the telescopic mechanism and the needle 201 to rotate around the axis of the rod where the hole to be positioned is located according to the angle.

[0047] In the above embodiment, the vertical plane on which the needle 201 is initially located can be set as a second reference plane, and the second reference plane needs to be parallel to the first reference plane. When the semi-finished valve body flows to the second workstation, since the second reference plane is parallel to the first reference plane, the angle between the axis of the hole to be positioned and the first reference plane is the same as the angle between the axis of the hole to be positioned and the second reference plane. The second rotating mechanism can control the rotation of the needle 201 based on the angle obtained by the aforementioned valve body hole positioning assembly 1. The needle 201 will rotate to the extension line of the axis of the hole to be positioned. The telescopic mechanism drives the needle 201 to extend so that it passes through the hole to be positioned. Then the second rotating mechanism controls the needle 201 to return to the second reference plane. The telescopic mechanism then drives the needle 201 to contract so that it withdraws from the hole to be positioned. In this way, the axis of the hole to be positioned is adjusted to the second reference plane.

[0048] More specifically, if Figure 4 As shown, the first rotating mechanism includes:

The first servo controller can accurately obtain the rotation angle of the output shaft of the first servo motor based on a given signal. In the above embodiment, the given signal is a signal triggered when the laser receiving device 102 receives the laser. After the first servo controller collects the angle between the axis of the hole to be positioned and the first reference plane, it controls the output shaft of the first servo motor to reset, so that the laser emitting device 101 and the laser receiving device 102 return to their initial positions.

[0053] More specifically, if Figure 4As shown, the first bracket includes: a first column 105 arranged on the valve body assembly line, and a first platform 106 arranged on the top of the first column 105; the first platform 106 extends to above the rod where the hole to be positioned is located on the valve body in the first workstation, and the first motor 103 is arranged on the top surface of the first platform 106.

[0057] Here, the second motor 202 can be a second servo motor with a second servo controller, which can control the output shaft of the second servo motor to rotate at a set angle. In the above embodiment, the set angle is the angle collected by the first servo controller.
