[0033] like Figure 1 As shown, the present invention provides a screw seat positioning device, which includes a screw seat body 1 , a first positioning member 2 , a connecting member 3 and a second positioning member 4 .

[0034] Among them, the first positioning member 2 is used for positioning and connecting with the positioning eyelet; the connecting member 3 is fixedly connected to the screw seat body 1 at one end and connected to the first positioning member 2 at the other end; the second positioning member 4 is provided on the screw seat body 1.

[0035] The screw seat positioning device provided in the embodiment of the present invention is a combination of a first positioning member 2, a connecting member 3, a second positioning member 4 and a screw seat body 1. The screw seat body 1 is positioned and installed in the positioning eyelet on the vehicle body through the first positioning member 2, the connecting member 3, and the second positioning member 4. That is to say, the screw seat positioning device includes a screw seat body 1.

[0036] Specifically, one end of the connecting member 3 is fixedly connected to the screw seat body 1, and can be fixedly connected by welding or integral molding, and the other end of the connecting member 3 is connected to the first positioning member 2. The first positioning member 2 is positioned and connected to the positioning eyelet on the vehicle body, so that the screw seat body 1 can be assembled into the positioning eyelet. The second positioning member 4 is installed on the screw seat body 1, and during the assembly process, the second positioning member 4 is used to achieve precise positioning of the screw seat body 1 and the positioning eyelet. Generally, the second positioning member 4 can be positioned in conjunction with the positioning groove / positioning hole next to the positioning eyelet or fit and clamped on the outer wall of the positioning eyelet to achieve precise positioning connection; in short, the second positioning member 4 is processed according to the peripheral structure of the positioning eyelet to ensure that the screw seat body 1 and the positioning eyelet are precisely positioned, that is, the requirements are met, such as: the two positioning cone structures described in the following embodiments can be positioned with the positioning grooves on both sides of the positioning eyelet, or clamped and fit on the outer wall of the positioning eyelet mounting structure to achieve positioning.

[0037] When the screw seat body 1 and the positioning eyelet are positioned, the screw seat body 1 can be installed in place by knocking the screw seat body 1. Specifically, the other end of the connecting piece 3 is interference fit with the positioning eyelet by knocking, so that the screw seat body 1 is installed in place.

[0038] It can be seen that the connecting member 3 of the present application realizes the connection between the screw seat body 1 and the first positioning member 2, and utilizes the positioning connection between the first positioning member 2 and the positioning eyelet, and realizes the precise positioning of the screw seat body 1 and the positioning eyelet through the second positioning member 4. Through the cooperation of the above two positioning members and the connecting member 3, the screw seat body 1 and the positioning eyelet are quickly positioned without manual linear positioning, which can meet the needs of fast and accurate positioning of the screw seat body 1, thereby improving assembly efficiency and assembly accuracy.

[0039] In one embodiment of the present invention, the first positioning member 2 includes: a screw sleeve, which is inserted into the positioning eyelet, and the outer wall of the screw sleeve forms an interference fit with the inner wall of the positioning eyelet. In this embodiment, the first positioning member 2 adopts a commonly used screw sleeve to achieve its positioning connection with the positioning eyelet. Specifically, the outer diameter of the screw sleeve needs to meet the requirements of achieving an interference fit with the positioning eyelet. In this embodiment, after the screw seat body 1 and the positioning eyelet are positioned, the screw sleeve is gradually inserted into the positioning eyelet by tapping the screw seat body 1 (if the buffer seat 6 is assembled according to the following embodiment, the buffer seat 6 is tapped). The interference fit is achieved by tapping, thereby ensuring a stable fit between the screw sleeve and the positioning eyelet.

[0040] In one embodiment of the present invention, the connecting member 3 includes a stud, one end of which is fixedly connected to the screw base body 1 and bolted to the screw sleeve. Specifically, the screw sleeve has an internal thread, and the stud has a matching external thread. One end of the stud is fixedly connected to the screw base body 1 or integrally formed, and the stud and the screw sleeve are bolted together, so that the screw base body 1 is positioned and connected via the stud and the screw sleeve. Thereafter, the screw sleeve is pressed into the positioning eyelet by hammering, completing the assembly of the screw base body 1 to the positioning eyelet.

[0041] The connection and positioning methods of the threaded sleeve and the stud are both made of existing parts, and it is sufficient to ensure that the inner and outer diameters and the threads match each other. There is no need to design and process new parts. The structure is simple and can be assembled and used on site.

[0042] In one embodiment of the present invention, a mounting hole is formed in the screw base body 1; the second positioning member 4 includes a positioning cone, which is positioned above the mounting hole and extends parallel to the direction of extension of the first positioning member 2. Specifically, the mounting holes are machined in the screw base body 1, and the positioning cones are inserted into the mounting holes one by one, with the tips of the positioning cones exposed on the side facing the positioning eyelet. When the screw base body 1 is assembled, the positioning cones can achieve precise positioning.

[0043] In one embodiment of the present invention, at least two second positioning members 4 are provided, and the at least two second positioning members 4 are centrally symmetrically arranged with the connecting member 3 as the center of symmetry. Preferably, in this embodiment, two second positioning members 4 are provided, and are symmetrically arranged on the left and right sides of the connecting member 3, respectively, so that precise positioning is achieved through the cooperation of the two second positioning members 4.

[0044] In one embodiment of the present invention, the screw seat positioning device further comprises a level detection device 5, disposed on the screw seat body 1, for detecting the levelness of the screw seat body 1 when the screw seat body 1 is assembled into the positioning eyelet. Preferably, the level detection device 5 comprises a spirit level, which serves as an auxiliary positioning means for the screw seat positioning device, capable of determining levelness and ensuring horizontal assembly of the screw seat body 1. Specifically, by observing the spirit level, precise leveling can be maintained during the positioning process, thereby completing the positioning preparation for the screw seat body 1 before installation.

[0045] In one embodiment of the present invention, the screw seat positioning device further comprises: a buffer seat 6, which is provided on a side of the screw seat body 1 away from the connector 3 and is used to mitigate the impact of knocking on the screw seat body 1 when the screw seat body 1 is assembled into the positioning eyelet. In this embodiment, by installing the buffer seat 6, the buffer seat 6 is used to withstand the knocking effect, thereby providing a buffer for the screw seat body 1 and preventing damage to parts. Preferably, the buffer seat 6 can be an elastomeric buffer seat, a metal spring buffer seat, a hydraulic buffer seat, an air spring buffer seat, or a composite buffer seat, to mitigate the impact on the screw seat body 1.

[0046] Among the above-mentioned buffer seats, the elastomeric buffer seat refers to one made of elastic materials such as rubber and polyurethane, which can provide good vibration reduction effect; the metal spring buffer seat refers to one that uses metal spring elements such as coil springs or leaf springs to absorb vibration energy; the hydraulic buffer seat refers to one that controls vibration through liquid damping, and may include air pressure or oil pressure systems to adjust the vibration reduction characteristics; the air spring buffer seat refers to one that uses an inflatable bladder as a vibration reduction element, and the pressure can be adjusted as needed to change its vibration reduction performance; the composite buffer seat refers to one that combines one or more of the above technologies to achieve better vibration reduction effect.
