Embodiment Construction
[0022] The embodiment of the present invention discloses a compression spring device for gears to avoid the inefficient operation of manually clamping and pressing the springs, improve the convenience of the process of pressing the springs into the gears, and at the same time ensure that the springs are pressed in. The depth in the gear remains consistent.
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The invention discloses a spring compression device for gears. The spring compression device comprises a base and a vertical positioning shaft fixedly connected to the base and further comprises a mold plate movably inserted into the positioning shaft. The mold plate is provided with multiple through holes for limiting springs to the length smaller than the length of grooves of the springs mounted on the gears from the natural length. The through holes correspond to the grooves in position. Compression blocks used for penetrating the through holes are movably connected to the upper portion of the positioning shaft. The compression blocks move in the vertical direction of the positioning shaft. The compression blocks penetrate the through holes downward to compress the springs so that the length of the springs can be smaller than the length of the grooves in the gears. The through holes are aligned with the grooves in the gears. The compression blocks further move to compress the springs into the grooves in the gears. By the adoption of the structural design, the operations of compressing the springs into the gears can be conducted at the same time, the low efficiency operations of sequentially clamping the springs through spring pliers and putting the springs into the grooves are avoided, the working efficiency of mounting the springs on the gears is improved greatly, the convenience is improved greatly, the labor saving degree is increased greatly, and meanwhile the depths of compressing the springs into the gears are kept unified.
Description
Technical field [0001] The invention relates to the technical field of mechanical tools, and more specifically, to a compression spring device for gears. Background technique [0002] The balance shaft technology is a widely used technology in motorcycle engines. The structure of the balance shaft is simple and practical, which can effectively reduce the vibration of the motorcycle and improve the driving comfort. [0003] A gear is provided on the balance shaft of a motorcycle engine, and a plurality of springs are embedded on the side of the gear, and the installation depth of the spring in the gear groove must be uniform and not higher than the end face of the gear. Since the length of the spring in the free state is greater than the length of the six grooves of the gear, it is an interference fit. In the process of installing the spring into the gear groove, the length of the spring must be compressed to less than the width of the gear groove before it can be installed. The cu...
