Description

Technical Field

[0001] The present invention belongs to the technical field of linear guide rails, and in particular relates to an anti-jamming linear guide rail. Background Art

[0002] Linear guides, also known as linear rails, slides, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion applications, and can bear a certain amount of torque. They can achieve high-precision linear motion under high load conditions. They can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, and other types.

[0003] In actual use, the existing linear guide rails rely on steel balls to make the slider slide on the guide rail body. The steel balls are easily worn out during long-term use. The existing linear guide rails are not convenient to replace the steel balls, resulting in a short service life of the linear guide rails. At the same time, in actual use, the existing linear guide rails are easily affected by foreign debris between the steel balls and the guide rail body, resulting in the debris being stuck between the steel balls and the guide rail body. Since the distance between the steel balls and the guide rail body is fixed, it is inconvenient for users to remove the debris, which easily causes the steel balls and the guide rail body to get stuck. Summary of the Invention

[0004] The object of the present invention is to provide a linear guide rail that prevents jamming, wherein the fixed motor rotates to rotate the fixed gear, and the toothed belt drives the installation gear to rotate the bidirectional threaded rod. The fixed clip can be separated from the installation slot by the limiting position of the fixed rod, and then the user can take the installation block and the steel ball out of the fixed frame, and then take the buckle out of the connecting piece, and then take the clamp out of the connecting piece, and then open the two installation blocks to make the docking rod disengage from the docking hole, and then after taking out the steel ball, a new steel ball can be replaced between the two installation blocks, and then the installation block can be restored to its original state, which can facilitate the user to replace and repair the steel ball. The worm can be rotated by rotating the connecting rod, and the worm gear can be engaged with the worm and the worm wheel, so that the fixed bidirectional threaded rod can be rotated. The fixed bidirectional threaded rod is rotated and the limiting position of the limiting rod can make the fixed block move and drive the fixed frame to move, so that the installation block drives the steel ball away from the guide rail body, so that the object stuck in the guide rail body can be taken out, and the installation block drives the steel ball to restore its original state by rotating the connecting rod, which can prevent the guide rail body from being stuck.

[0022] (1) In the present invention, the fixed motor rotates to rotate the fixed gear, and the toothed belt drives the installation gear to drive the installation bidirectional threaded rod to rotate.

Anti-stuck guide rail: When the slider (2) is stuck in the guide rail body (1), the connecting rod (301) is rotated. The rotation of the connecting rod (301) can cause the worm (303) to rotate. Through the meshing of the worm (303) and the worm wheel (304), the worm wheel (304) can drive the fixed bidirectional threaded rod (305) to rotate. Through the rotation of the fixed bidirectional threaded rod (305) and the limiting of the limiting rod (306), the fixed block (307) can be moved to drive the fixed frame (401) to move, so that the installation block (402) drives the steel ball (409) away from the guide rail body (1), so that the object stuck in the guide rail body (1) can be removed. Then, by rotating the connecting rod (301), the installation block (402) drives the steel ball (409) to restore the original state, thereby preventing the guide rail body (1) from being stuck. S2. Disassembly and maintenance: When the steel ball (409) needs to be disassembled and replaced, the user first turns on the fixed motor (403), and the fixed motor (403) rotates, thereby rotating the fixed gear (404), and through the transmission of the toothed belt, the mounting gear (405) drives the mounting bidirectional threaded rod (406) to rotate, and through the limit of the fixing rod (407), the fixing clip (408) can be disengaged from the mounting groove (411), and then the user can remove the mounting block (402) and the steel ball (409) from the fixing frame (401); S3, replacement and maintenance: After removing the mounting block (402) and the steel ball (409), remove the buckle (418) from the connecting piece (414), then remove the clamp (416) from the connecting piece (414), then open the two mounting blocks (402), so that the docking rod (412) is separated from the docking hole (413), and then remove the steel ball (409). Then, replace the new steel ball (409) between the two mounting blocks (402), and then restore the mounting block (402) to its original state to complete the replacement of the steel ball (409).
