Description

technical field [0001] The invention relates to the technical field of laser marking machines, in particular to an encoder fixing device. Background technique [0002] Since the laser marking machine came out, it has been favored by the majority of manufacturers with its unique advantages and excellent performance, and it has been more and more widely used in various fields. Laser marking does not touch the workpiece during the marking process. It is superior to traditional methods such as chemical corrosion, mechanical stamping, electric spark writing, etc. Laser marking does not have any special requirements for the processed material except for the laser that can effectively absorb this wavelength, and it has no loss, no disturbance, no deformation to the workpiece, and the processing pattern is also flexible and diverse due to the use of computer control. The automation degree of laser marking is high, and the processing process has no pollution to the environment. Chan...

Problems solved by technology

However, the coding wheel of the existing laser marking machine is directly installed on the encoder through a shaft coupling. During use, most of the impact on the coding wheel is transmitted to the encoder, which is very easy to damage the encoder and reduce the loss of the encoder. The service life, the price of the encoder is high, which increases the production cost. Because the encoder is fixed, the tube sometimes fluctuates, especially when the machine is just started and used, the tube will hit the code wheel, which will reduce the service life of the machine and affect the work efficiency.
