Automatic-adjustment air hammer

Abstract

The invention discloses an automatic-adjustment air hammer which comprises a hammer body, a hammer core, a hammer core collision block, a hammer head and a hammer body end cover. The hammer head and the hammer body end cover are fixedly arranged at the two ends of the hammer body respectively, the hammer core is arranged in the hammer body in a sliding mode, and the hammer core collision block is fixed to one end of the hammer core. An air inlet, a first exhaust port and a second exhaust port are formed in the outer wall of the hammer body, a first annular groove connected with the air inlet, a second annular groove communicated with the first exhaust port and a third annular groove communicated with the second exhaust port are formed in the inner wall of the hammer body, a first airflow hole is formed in one end of the hammer core, a second airflow hole is formed in the other end of the hammer core and the first airflow hole and the second air flow hole are alternately communicated with the air inlet in the process of realizing movement of the hammer core. The automatic-adjustment air hammer is simple and reasonable in structure, continuous impact force can be obtained simply by leading airflow with pressure into the hammer body, and therefore the automatic-adjustment air hammer is higher in reliability and more convenient to use.

Description

technical field [0001] The invention relates to an air hammer, in particular to an automatically adjusting air hammer, which can automatically adjust its own linear reciprocating motion by feeding gas, and belongs to the field of test equipment. Background technique [0002] Air hammers are widely used in industrial equipment, especially in casting equipment, where the impact force of air hammers can be used to clean residues on castings. With the continuous expansion of the application of air hammer, it has been applied to the field of test equipment. In the field of test equipment, people use the impact force of the air hammer to excite a work table to generate a certain acceleration, so as to realize the accelerated test of the product life. If the impact force of the air hammer is adjusted, the work can be realized. The change of the acceleration value of the table surface, in this way, can realize different levels of accelerated life tests on the product by using diffe...

Problems solved by technology

[0007] The first type of air hammer relies on electromagnetic drive to realize the movement of the hammer core. In addition, the air pressure at the air inlet needs to be adjusted to change the size of the impact force, which makes the control of the air hammer more complicated; the second type of air hammer Continuously change the intake or discharge of the two air ports through the air circuit control to realize the linear reciprocating movement of the hammer core, which also makes the control of the air hammer more complicated

Therefore, the movement speed of the hammer core of the above two types of air hammers is limited to a certain extent due to complex control, which directly affects the impact force of the air hammer.
