Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to an end surface spring grinding device for processing disc springs. Background Art

[0002] The butterfly spring is a kind of mechanical accessory that looks like a circular gasket and is made of different metals. It is called a butterfly spring because of its bowl-shaped appearance. Generally speaking, it works by providing sufficient elastic extension through a considerable number of superpositions. Due to its variable stiffness characteristics and compact installation, it is widely used in the fields of mechanical equipment industry, petroleum industry, automobile industry, and aerospace industry, and has largely replaced cylindrical spiral springs. In order to ensure the processing quality of the butterfly spring, its end face will be polished through a spring grinding device to ensure that there will be no sharp corners and burrs on the corners of the spring.

[0003] Common spring grinding devices generally fix the spring through a clamp, and then grind its end face through a grinding mechanism such as a grinding wheel. However, due to the different inner hole diameters of the disc springs, this method requires the use of pads to repeatedly adjust the positioning when clamping different disc springs, making the entire spring grinding process time-consuming and labor-intensive, and cannot meet the working requirements of the spring grinding device. For this reason, an end face spring grinding device for disc spring processing is proposed. Utility Model Content

[0010] The shaft sleeve is screwed onto the outside of the stud, and a connecting sleeve is sleeved on the outside of the stud at the left side of the shaft sleeve. The outer circumference of the connecting sleeve is movably connected to the second transmission connecting rod through a bearing, and the outer ends of the second transmission connecting rod are movably connected to the corresponding positions on the inner side of the arc-shaped clamping plate through bearings.

[0011] Preferably, the number of the first transmission connecting rod, the second transmission connecting rod and the arc-shaped clamping plate is 3-5 groups, and the length of the arc-shaped clamping plate is greater than that of the I-beam, thereby improving the stability of the disc spring clamping.

[0012] Preferably, a snap ring is connected to the right side of the connecting sleeve, and the snap ring is clamped inside the sleeve so that it will not rotate when the connecting sleeve moves left and right. The inner diameter of the connecting sleeve is larger than the stud, preventing interference with the thread when the connecting sleeve moves left and right.
