Description

Technical Field

[0001] The invention relates to the technical field of machine tool accessories, in particular to a machine tool protective door with a self-adaptive adjustment function. Background Art

[0002] The machine tool protective door is an important protective device for machine tools, which provides an important barrier between the operator and the machine tool. When the machine tool stops running, open the protective door before the workpiece can be loaded and unloaded. When the machine tool is running, close the protective door to prevent the operator from being injured, and at the same time observe the real-time status of the workpiece processing. Existing machine tool protective doors generally adopt a rigid connection structure, and the assembly flatness of the door frame and the machine tool guide rail must be controlled within ±0.3mm, otherwise it is easy to cause the door body to get stuck or the seal to fail. In order to ensure the installation accuracy, gaskets or wedge blocks are usually used for gap adjustment, but this method can only be adjusted during the installation stage and cannot adapt to the mechanical deformation or foundation settlement of the protective door during long-term use. In addition, the vibration and thermal deformation during the operation of the machine tool will also aggravate the deviation of the protective door body. Traditional protective doors lack real-time compensation capabilities, and the protective door seals are severely worn.

[0003] In the prior art, three methods are commonly used to improve the compensation capacity of protective doors: elastic material compensation, mechanical adjustment compensation, or intelligent compensation system. The elastic material compensation method is to embed a rubber strip in the door frame and use the deformation of the material to absorb the error. However, rubber is prone to aging due to long-term pressure and has a limited deformation amount (maximum compression rate ≤ 15%), making it difficult to compensate for installation deviations exceeding 1.5mm. Mechanical adjustment compensation uses a threaded top screw to fine-tune the position of the door body. Although this method can improve the adjustment accuracy, it requires repeated manual operation, and the adjustment range is limited by the screw stroke. The intelligent compensation system introduces a servo motor to drive the door body displacement for adjustment, but the intelligent compensation system is highly complex, costly, and relies on external sensors. External sensors are easily contaminated by cutting fluid and fail, and have high maintenance costs. Summary of the invention

[0004] Based on this, it is necessary to provide a machine tool protective door with adaptive adjustment function to address the above technical problems.
