Description

Technical Field

[0001] The utility model relates to the technical field of precision surface grinders, in particular to a closed protective cover for a numerically controlled precision surface grinder. Background Art

[0002] Precision surface grinders can grind various planes and complex shaped surfaces. They are suitable for grinding processes that do not require motorized feed. The spindle uses P4-grade precision rolling bearings and labyrinth seals, which are waterproof and dustproof, with smooth movement and high precision. Ball steel guides are used in the longitudinal direction, which are easy and flexible to operate. The columns use large-span guides with good rigidity and high stability. The whole machine uses a manual oil pump for centralized lubrication. The main purpose of using a closed protective cover on a precision surface grinder is to protect the operator and the environment from harmful substances such as debris, liquid splashes, and dust generated during the grinding process. It can also prevent external impurities from entering the machine and affecting the processing quality.

[0003] The protective covers currently used for precision surface grinders generally have glass plates on their door panels to facilitate operators to observe the grinding process and ensure the position and status of the workpiece and tool. However, when the grinder is working, the glass plate will be affected by pollutants such as dust and liquid splashes generated during grinding, resulting in blurred or unclear vision, affecting the operator's observation and control of the processing process and increasing operational risks. The obstructed field of view will make it difficult for the operator to accurately judge the processing status and adjust the processing parameters, which may affect the processing quality and product accuracy.

At this time, the threaded sleeve 803 will drive the guide plate 804 to move, and then the dust and splashed liquid on the surface of the glass plate 4 are cleaned through the scraper strip 805 and the rag strip 806 on the front side of the guide plate 804.

[0035] Working principle: When the operator observes that the glass plate 4 is blocked by dust or other splashing liquid, the operator turns on the motor 801 to make the first transmission wheel 807 drive the transmission belt 808 to drive the second transmission wheel 809 to rotate. When the second transmission wheel 809 rotates, it will drive the threaded rod 802 to rotate. At this time, the threaded sleeve 803 will drive the guide plate 804 to move.

When the user needs to maintain the sound insulation plate 52, first pull the pull plate 56 to stretch the tension spring 55. At this time, the pull plate 56 will drive the insertion rod 57 to disengage from the inner cavity of the insertion plate 53, and then the sound insulation plate 52 can be taken out through the insertion plate 53.
