Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] The expansion fixture for the joint surface of the natural section of the part includes an upper expansion beam 2 and a lower expansion beam 9, and an expansion tie rod 6 is arranged between the upper expansion beam 2 and the lower expansion beam 9, and the upper expansion beam 2 and the lower expansion beam Expansion blocks 3 are arranged on the expansion beam 9, and expansion platforms 17 are provided on both sides of the expansion tie rod 6. The top surface I16 of the expansion block 3 is tangent to the top surface II of the expansion platform 17, and the top surface I16 Both have an inclination angle and are opposite to the top surface II.
[0031] The expansion block 3 is fixed on the upper expansion beam 2 and the lower expansion beam 9 through bolts 5 and nuts 4;
[0032] One end of the upper expansion broken beam 2 and the lower expansio...

A fracture splitting fixture for natural fracture surface joint surfaces of parts is characterized by comprising fracture splitting beams which comprise an upper fracture splitting beam and a lower fracture splitting beam, the upper and lower fracture splitting beams are provided with fracture splitting bocks of different fracture surface angles respectively, and the fracture splitting blocks are arranged according to sizes of top surface angles of the fracture splitting blocks and fixed on the upper and lower fracture splitting beams sequentially; and a fracture splitting pull rod is arranged between the upper and lower fracture splitting beams, and the fracture splitting pull rod is provided with fracture splitting tables matched with the fracture splitting blocks on the upper and lower fracture splitting beams. The fracture surface joint surfaces are uneven, tightly attached and capable of stopping relative sliding between the joint surfaces and reducing bolt shearing force. According to the fracture surface joint surfaces, small local deformation can be resisted, entering of moisture can be reduced, the defect of corrosion on joint surfaces in the prior art is overcome, and service lives of the parts can be prolonged.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and relates to an expansion fixture for a joint surface of a natural section of a part, and also relates to an expansion breaking method of the joint surface. Background technique [0002] The joint surface of the parts in the existing mechanical structure is generally a plane, and the connection of the joint surface is realized through the flange. Therefore, the two joint surfaces must be flat, and the connecting bolts used in the flange must have a certain shear resistance. Need to be free from dust and water. This joint surface is generally obtained by milling, the process is simple, and the installation is convenient, but its effective joint area is small, and it is easy to produce slippage between planes in a vibrating environment, resulting in wear of the joint surface, causing moisture to enter the joint surface to cause corrosion, affecting Connection effect.
