The invention relates to the technical field of sliding body braking, in particular to a sliding body brake and a linear motor catapult. The sliding body brake comprises a sliding block, insertion parts are arranged on the left side and the right side of the sliding block, a mounting hole is formed in the sliding block, an opening is formed in the mounting hole in the end face of at least one insertion part, and a top block, an elastic piece and a friction block are arranged in the mounting hole; the end surface of the friction block is exposed outside the insertion part to be in frictional contact with the groove wall of the sliding body guide rail groove; the sliding block is in threaded connection with an adjusting screw, and the end of the adjusting screw is matched with the ejector block through a pushing matching structure, so that when the adjusting screw is screwed into the sliding block, the ejector block is pushed to move outwards, and then the end face of the friction block elastically abuts against the groove wall of the sliding body guide rail groove by compressing the elastic piece. The sliding body brake is flexible in installation mode, can be installed in an up-and-down mode and a left-and-right mode, and is convenient to install as long as the insertion parts on the two sides are inserted into the guide rail grooves. And meanwhile, stepless adjustment of the braking force within a certain range can be achieved only by adjusting the screwing-in amount of the adjusting screw, and adaptability is high.

    本发明涉及滑体制动技术领域,具体涉及一种滑体制动器及直线电机弹射器,滑体制动器包括滑块,滑块左右两侧设有插入部,滑块内设有安装孔,安装孔在至少一个插入部端面上有开口,安装孔内装有顶块、弹性件和摩擦块,摩擦块端面露出在插入部外部以与滑体导轨槽的槽壁摩擦接触;滑块上螺纹连接有调节螺钉,调节螺钉端部和顶块之间通过顶推配合结构进行配合,以在调节螺钉向滑块内旋入时推动顶块向外移动进而通过压缩弹性件使摩擦块的端面弹性顶压在滑体导轨槽的槽壁上。本发明的滑体制动器安装方式灵活,不分上下和左右,两侧插入部对准导轨槽插入即可,安装方便。同时只需调整调节螺钉的旋入量,即可实现制动力在一定范围内无级调节,适应性强。
