The invention discloses a front fork steel bowl assembly of a battery car and a bicycle. The assembly is composed of a steel bowl, a steel ball and ball frame and a check ring, and is characterized inthat two symmetrical clamping blocks are arranged at the inner side of an opening of the steel bowl, the steel ball and ball frame is placed in the steel bowl, the check ring is placed on the steel ball and ball frame, and when the steel ball and ball frame is horizontally placed in the steel bowl, the clamping blocks can prevent the steel ball and ball frame from moving outwards, and the clamping blocks are formed together when the steel bowl is punched. The front fork steel bowl assembly has the beneficial effects that an accessory of a clamping ring is saved, and the product cost is reduced; and meanwhile, a procedure of placing the clamping ring is omitted, so that the production efficiency is improved. Compared with the process that an electric welding machine is used for spot welding of three convex points , three times of electric welding are needed, and smoke can be generated, the existing steel bowl with the clamping blocks is simple to assemble, smoke cannot be generated, and the quality control is more stable.
本发明公开了一种电瓶车自行车的前叉钢碗组件,由钢碗、钢珠及球架和挡圈组成,其特征在于:所述的钢碗的口内侧有对称的二个卡块,在钢碗内放有钢珠及球架,在钢珠及球架上放有挡圈,钢珠及球架在钢碗内平放时,卡块会挡住钢珠及球架向外移动,所述的卡块是在冲压钢碗时一起成型的。有益效果是节省一个卡圈的配件,降低了产品的成本;同时少了一道放置卡圈的工序,提高了生产效率;比较用电焊机点焊上去三个凸点的工艺,需要三次电焊,还会产生烟雾,现在用带卡块的钢碗,装配简单、不会产生烟雾,在质量控制上也比较稳定。
