Abstract
Description
Technical Field
[0001] The present invention particularly relates to a limiting device for an anti-slip machine tool. Background Art
[0002] Machine tools are mechanical equipment used to process materials such as metals, plastics, and ceramics. They can process raw materials into workpieces with specific shapes, sizes, and surface quality through processes such as cutting, grinding, sawing, and drilling. During processing, the workpiece to be processed is generally moved to a predetermined position by a transport pallet, which is driven by a motor to rotate the lead screw to cause it to move horizontally.
[0003] When the existing machine tool transport pallet is moving, in order to limit the excessive movement of the transport pallet, some will use a proximity switch and a positioning baffle to perform real-time detection of the position of the transport pallet, so as to stop the motor drive after the transport pallet is moved into place. However, due to vibration during machine tool processing or loose clamping of the positioning baffle, the positioning baffle position may slide and cannot be stably maintained in a specific position. After movement occurs, it is very easy to cause the transport pallet to move excessively, affecting the safety during processing. For this reason, we propose a limit device for anti-slip machine tools. Summary of the Invention
[0004] The object of the present invention is to provide a limiting device for an anti-slip machine tool to solve the problems raised in the above background technology.

[0037] A vibration damping assembly is provided on the rear surface of the mounting base plate 1 so as to contact the machine tool during installation, thereby reducing the transmission of vibration to the mounting base plate 1;
[0038] The guide slide plate 2 is detachably fixed to the front surface of the mounting base 1, and an assembly space is formed between the guide slide plate 2 and the mounting base 1. The guide slide plate 2 has anti-slip teeth 202 to better limit and fix the left baffle 5 and the right baffle 3 to prevent the two from sliding;
[0039] Left baffle 5;
[0040] The right baffle 3 is arranged at one end of the inner side of the assembly space, and the left baffle 5 and the right baffle 3 are arranged side by side.

[0041] At least two sets of bolt assemblies are respectively arranged on the left baffle 5 and the right baffle 3 to stop the movement of the moving part of the machine tool when the bolt assembly corresponds to the proximity switch 4, so as to better prevent the moving part of the machine tool from moving excessively when moving left and right.
[0042] Preferably, the cross-section of the anti-slip tooth pattern 202 is an isosceles triangle, and the left baffle 5 and the right baffle 3 are both provided with oblique tooth patterns that mesh with the anti-slip tooth patterns 202, so as to prevent the left baffle 5 and the right baffle 3 from sliding when the distance between the guide slide plate 2 and the mounting base plate 1 increases through the cooperation of the tooth patterns.
[0043] Preferably, the tip angle of the anti-slip tooth pattern 202 is 50° to 60°.
[0044] Preferably, the upper surface of the left baffle 5 is provided with a first oblique tooth pattern 501 guiding to the left side, and the tooth tip angle of the first oblique tooth pattern 501 is 25° to 30°, so that when the distance between the guide slide 2 and the mounting base 1 increases, the left baffle 5 can only be guided to the left side.
