压扣组件

Abstract

本申请涉及自动化技术领域，旨在解决一些已知的压扣机构存在难以兼顾低成本和高精度的技术问题，提供压扣组件，其包括安装件、驱动件、输出轴及抵压件。驱动件设于安装件。输出轴沿第一方向的一端传动连接驱动件，输出轴的另一端设有滑动部。抵压件的一端设有滑槽，滑动部滑动配合于滑槽内，抵压件的中部设有枢接部，枢接部可转动地连接安装件，抵压件的另一端凸设有抵压头。驱动件用于驱动输出轴沿第一方向运动，以使滑动部沿滑槽的长度方向运动，进而带动抵压件绕安装件转动，进而使抵压头绕枢接部转动，以在第一方向靠近或远离安装件。本申请的有益效果是兼顾降低压扣组件的成本及提高压合精度。

Claims

1. A press stud assembly, characterized in that, include: Installation components; A driving component, wherein the driving component is disposed on the mounting component; An output shaft, one end of which is connected to the driving member along a first direction, and the other end of which is provided with a sliding part; A pressing member, one end of which is provided with a sliding groove, the sliding part being slidably fitted in the sliding groove, the middle part of which is provided with a pivot part, the pivot part being rotatably connected to the mounting part, and the other end of which is provided with a pressing head; The driving member is used to drive the output shaft to move along the first direction, so that the sliding part moves along the length direction of the groove, thereby driving the pressing member to rotate around the mounting member, and thereby causing the pressing head to rotate around the pivot part, so as to move closer to or further away from the mounting member in the first direction.

2. The snap-fit ​​assembly according to claim 1, characterized in that: The pressing member includes a connecting part and a pressing part. One end of the connecting part is provided with the sliding groove. The pressing part is bent and connected to the other end of the connecting part. The end of the pressing part away from the connecting part is connected to the pressing head. The connecting part and the pressing part are provided with the pivot part at the connection.

3. The snap-fit ​​assembly according to claim 1, characterized in that: The end of the pressing head away from the pivot portion defines a pressing arc surface, and the axis of the pressing arc surface is perpendicular to the first direction.

4. The snap-fit ​​assembly according to claim 3, characterized in that: The pressing head also has a guide surface, one end of which is connected to the pressing arc surface, and the other end of which is inclined in the direction close to the pivot.

5. The snap-fit ​​assembly according to claim 1, characterized in that: The length of the groove is greater than the width of the sliding part, and the groove has a first end and a second end disposed along its length direction; The pressing member has an initial position and a pressing position. When the pressing member is in the initial position, the sliding part abuts against the first end, and the pressing head is located on one side of the mounting member along the second direction. When the pressing member is in the pressing position, the sliding part abuts against the second end, and the pressing head is directly opposite the mounting member along the first direction. The second direction is perpendicular to or intersects the first direction at an angle.

6. The snap-fit ​​assembly according to claim 1, characterized in that: The mounting component has a clearance groove, and the pivot part is located in the clearance groove. The pivot part is rotatably connected to the mounting component so as to drive the middle part of the pressing member to rotate in the clearance groove.

7. The snap-fit ​​assembly according to claim 6, characterized in that: The sliding part is located on one side of the mounting component; The snap fastener assembly further includes a first limiting part, which is located on the side of the mounting member away from the driving member. The first limiting part covers the clearance groove and is used to limit the pressing member to prevent the pressing head from rotating toward the side of the mounting member away from the driving member.

8. The snap-fit ​​assembly according to claim 1, characterized in that: The snap-fit ​​assembly also includes a base component; The mounting component is movably disposed on the base component along the first direction.

9. The snap-fit ​​assembly according to claim 8, characterized in that: The base component has multiple scale sections on its side, and the multiple scale sections are distributed at equal intervals along the first direction; The snap fastener assembly also includes a guide member, one end of which is connected to the mounting member and the other end of which points to the plurality of scale portions. The extension direction of the guide member is parallel to the extension direction of the scale portions.

10. The snap-fit ​​assembly according to claim 8, characterized in that: The snap fastening assembly further includes a first guide and a second guide. The first guide is connected to the base component and extends along the first direction. The second guide is connected to the mounting component and is slidably disposed on the first guide along the first direction. The snap fastening assembly further includes a second limiting portion, one end of which is connected to the base member, and the other end of which extends in a direction close to the mounting member. A portion of the orthographic projection of the second guide member along the first direction is located on the portion of the second limiting portion that extends out of the base member.
