This invention relates to the field of self-centering grinding fixtures, and discloses a universal self-centering fixture for grinding small cylindrical parts. The fixture includes a mandrel assembly, an externally mounted locking block, an externally mounted locking cover, and a set of limit screws evenly distributed between the locking cover and the locking block. The mandrel assembly is externally threaded with locking screws. A roller guide is mounted on the left side of the mandrel assembly, and pins are mounted at both ends of the roller guide. A second spring is externally connected to the push rod. This universal self-centering fixture for grinding small cylindrical parts avoids the limitations of traditional fixtures in providing high-precision machining conditions for the roller guide. Furthermore, the added set of limit screws automatically locks the position of the limit screws when fixing the locking cover and locking block, avoiding the need for pins to lock the position of the limit screws in traditional fixtures. This reduces the fixing steps and increases the machining speed of the workpiece.

The utility model provides a mounting assembly and power distribution equipment, the mounting assembly is applied to the power distribution equipment, the power distribution equipment comprises a busbar and a plurality of functional modules electrically connected with the busbar, the mounting assembly comprises an outer shell, an inner shell, a first insulating column and a second insulating column, and the outer shell is provided with a mounting inner wall; the inner shell is configured to accommodate a plurality of functional modules, and the inner shell is arranged in the outer shell; one end of the first insulating column is fixed with the mounting inner wall, the other end of the first insulating column is configured to be fixed with the busbar, and a first preset distance is formed between the busbar and the mounting inner wall; the second insulating column and the first insulating column are arranged at an interval, one end of the second insulating column is fixed to the mounting inner wall, the other end of the second insulating column is fixed to the inner shell, a second preset distance is formed between the inner shell and the mounting inner wall, and the second preset distance is larger than the first preset distance. The above arrangement can simplify the structure of the power distribution equipment, reduce the production cost of the power distribution equipment, and meet the insulation requirements between the busbar and the outer shell and between the inner shell and the outer shell.
