The utility model relates to a fixture, in particular, a welding fixture for a car skylight, which comprises an mounting plate, a back plate, a cylinder and a card head. The top of the mounting plate is welded with a back plate. The back plate is vertically arranged, and a cylinder on one side of the back plate is provided vertically, and the top of the cylinder is passed through the top of the push rod through the top. The rear part of the card head is connected with the top of the back plate through a connecting rod. A telescopic piece is arranged on the position of the mounting plate and located on the side of the back plate. The telescopic member is provided with a top plate through a telescopic rod. The front end of the card head is provided with a position plate for the top plate. The head and the top of the back plate are arranged between the top and the top of the back plate. The gap in the frame of the car's skylight is closed; the gap in the frame of the car skylight is built through the head and back of the car, so that the frame can not move laterally; through the extra support of the telescopic piece, the impact of the groove part of the car's skylight with the grooves is reduced; the guardrail is equipped with a circular cylinder to prevent the entanglement of the welding machine on the outside of the fixture. It is.
【技术实现步骤摘要】
汽车天窗焊接夹具
本技术涉及一种夹具,尤其是汽车天窗焊接夹具。
技术介绍
天窗焊接工序主要是通过夹具夹紧天窗玻璃外周的边框,然后在边框上焊接诸如滑块等部件的过程。现有夹具一般是直接夹取边框外侧,因为边框内侧设有用于卡入玻璃的凹槽,一般的夹具夹持边框内侧可导致凹槽变形。然而现有技术存在一不足,由于只夹住边框外侧,焊接时如果横向敲击(碰焊)边框,可能使得边框在夹具内发生偏移。
技术实现思路
针对现有技术的不足,本技术提供一种可夹紧天窗边框而不会损伤边框凹槽的夹具。本技术的技术方案为:汽车天窗焊接夹具,其特征在于:它包括安装板、背板、气缸和卡头,所述安装板和气缸通过螺栓安装在底座上,所述安装板顶部焊接有背板,所述背板竖直设置,所述背板一侧的底座上设有气缸,所述气缸的推杆竖直朝上设置,所述推杆顶端通过转轴设置有卡头,所述卡头后部通过连杆连接背板顶部,所述安装板上且位于背板一侧的位置上设置有伸缩件,所述伸缩件通过一伸缩杆设置有顶板,所述卡头前端对应顶板设置有一限位板,所述卡头和背板顶部之间设置有配合汽车天窗边框的缺口。所述背板顶部对应卡头底面设置有垫板。所述背板环绕气缸设有护栏。其作用是防止焊接时焊机的电缆和数据线等部件拖动时缠绕气缸。所述缺口对应汽车天窗边框带有凹槽部分的位置上其高度比该部分的汽车天窗边框厚度要大。本技术的使用方法:将伸缩杆收缩,将气缸收缩,将待加工汽车天窗的边框放入缺口处,然后同时开启伸缩杆和气缸,伸缩杆通过伸展顶住边框带有凹槽的部分,由于伸缩杆的动力机构为弹簧,只具有支撑作用而不会夹坏边框,另外所述卡头和背板顶部之间设置有配合汽车天窗边框的缺口使得 ...
