Description

technical field [0001] The invention belongs to the field of fluid polishing processing, and in particular relates to a mechanical structure of a horizontal reciprocating abrasive flow polishing machine, which is suitable for finishing the inner holes of mechanical parts. Background technique [0002] Polishing is an important process in processing. With the gradual development of machinery to precision and refinement, the requirements for processing quality are getting higher and higher. The traditional polishing process cannot complete the polishing process on the inner surface of some complex holes or small holes. , which will seriously affect the performance of the parts. The emerging abrasive fluid polishing technology mainly removes the burrs on the inner wall of complex holes through abrasive extrusion jetting, which can effectively polish the inner walls of complex holes, ensure high processing quality, and meet the precision requirements of products.

Problems solved by technology

[0003] The existing abrasive fluid polishing structure is complicated. The main mechanical structure is composed of the upper material cylinder, the lower material cylinder and the supporting lifting extrusion device. Although this type of polishing machine realizes simple reciprocating motion, it needs two single-acting oil cylinders to cross Reciprocating motion not only increases the cost, but also reduces the processing efficiency

CN201856159U discloses a structure that utilizes the combination of upper and lower mold bases to push abrasives to realize workpiece polishing. This structure realizes the reciprocating motion of fluid on the inner wall of the workpiece, but requires two power devices. On the one hand, it increases the cost of the structure, and on the other On the one hand, it requires higher control accuracy

Compared with it, the patent of the present invention has the advantage of using a double-acting hydraulic cylinder to provide two-way power, which reduces the structural cost, and realizes reciprocating motion, and the control method is simple; CN205674010U discloses a structure for deburring and polishing machine with cross holes in the abrasive fluid. The single-acting hydraulic cylinder and the barrel are placed up and down, and the structural stability is weak. During the machine movement, the vibration is relatively large, which requires high strength of the support. Moreover, the single-acting hydraulic cylinder used in this structure can only move in one direction, and the return stroke of the hydraulic cylinder is at No load, waste of energy, low efficiency

CN204604068U discloses a complex inner hole abrasive fluid automatic polishing structure, the structure utilizes a slope to realize the abrasive backflow to the barrel, and can realize the reciprocating reuse of the abrasive, but the structure cannot be controlled, and the abrasive will flow back to the barrel during the movement The pressure head cannot reach the barrel
