Reciprocating motion device

Abstract

The invention provides a reciprocating motion device which comprises a shell, a driving assembly and a functional assembly. An electromagnet is arranged on the shell. When the electromagnet is powered on, the driving assembly can be driven to move so as to enable the functional assembly to move from a first position to a second position. When the electromagnet is powered off, the driving assembly can be driven by the driving assembly to move so as to enable the functional assembly to move from the second position to the first position. Or the functional assembly can be driven by the functional assembly to move from the second position to the first position, the first position is the initial position, and the second position is the target position. In the reciprocating motion device, the electromagnet is used for generating a magnetic field, the reciprocating impact action of a functional head of the reciprocating motion device is achieved through magnetic force, accuracy is high, and the speed is high; and compared with an existing automatic reciprocating motion device, the reciprocating motion device has the advantages of being simpler in structure, time-saving, labor-saving and high in accuracy and is beneficial to application and popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a reciprocating device. Background technique [0002] In mechanical motion, reciprocating motion is a very common type of motion, which can achieve multiple functions, such as drilling, cutting, grinding, workpiece transfer, etc. A series of operations involve reciprocating motion, even in medical equipment. involves. [0003] Punching is a common process, and the depth and accuracy of the punching position are very high on some precision instruments or equipment, but the existing punching equipment has the defects of low efficiency and low accuracy, and at the same time Manual punching is time-consuming and labor-intensive, so it is urgent to develop a device with high punching efficiency, high accuracy, and time-saving and labor-saving.

[0003] Punching is a common process, and the depth and accuracy of the punching position are very high on some precision instruments or equipment, but the existing punching equipment has the defects of low efficiency and low accuracy, and at the same time Manual drilling is time-consuming and labor-intensive, so it is urgent to develop a device with high drilling efficiency, high accuracy, and time-saving and labor-saving

[0004] Patent document CN 208584621U discloses a hand-operated hole puncher, which includes a support frame, a vertical shaft assembly, and a drive mechanism; the vertical shaft assembly is installed on the support frame and passes through the support frame to complete axial movement, and the drive mechanism is installed on the support frame On the frame and in contact with the vertical shaft assembly, it drives the corresponding components of the vertical shaft assembly; by operating the driving mechanism, the rotational motion of the driving mechanism is converted into the vertical shaft assembly’s up and down reciprocating motion; the vertical shaft assembly generates the impact force of the reciprocating motion, and The corresponding components of the support part cooperate to punch holes in the article, but this design is time-consuming and laborious and the accuracy is not high
