[0002] Ball linear guides are commonly used linear motion mechanical structures in the machining industry. Rolling steel balls are used as the medium between the moving and fixed elements. Therefore, they have the advantages of high precision, good rigidity, small motion resistance, smooth operation, large load, and automatic self-alignment. They are widely used in the equipment manufacturing industry.

[0003] Linear guides are generally fixed to a solid equipment foundation using hexagon socket head screws. In order to prevent the screws from rusting and clogging with oil and to maintain their appearance, a round plastic cover with a taper at the front end is used to seal the guide screw holes. Due to the interference fit between the two, and the small size and light weight of the hole covers, it is not conducive to batch installation using mechanized equipment. Currently, only the traditional method of manual placement and hammering can be used. Not only is the noise loud, but the installation is uneven and it is easy to damage the guide surface, thereby reducing the installation accuracy. Especially when installing the hole covers in the horizontal direction, the manually placed hole covers are easy to fall. If the guide rail is in a low position, manual operation is even more inconvenient and the production efficiency is very low. Therefore, the market has an urgent need for devices that can automatically place and quickly install hole covers. Summary of the invention

The operator holds the rotating pressure handle 16 and pushes it to one side of the ball linear guide 1. The steel ball 11 meets the ball linear guide 1 When the screw hole is drilled, it rolls into the hole and automatically positions. After the operator senses the vibration and resistance, he stops pushing and turns to press the rotating pressure handle 16 around the hinge shaft 17. The rotating pressure handle 16 drives the push rod cover 18 to push the push rod 8. The push rod 8 pushes the current hole cover 4.

The middle part of the lower end of the upper adjacent hole cover 5 is pushed and rises along the chamfered arc surface of the push rod 8 to separate from the current hole cover 4. When the current hole cover 4 is pushed, the conical surface is automatically positioned in the hole. The operator uses the lever principle to press the current hole cover 4 into the screw hole of the ball linear guide 1. The front of the current hole cover 4 is aligned with the roller When the ball linear guide 1 is flush, the rotating pressure handle 16 reaches the limit position, the operator stops pressurizing, lifts the rotating pressure handle 16, the push rod reset spring 21 drives the push rod pressure cover 18 and the push rod 8 to reset and retract, and the upper adjacent hole cover 5 falls along the chamfered arc surface of the push rod 8 to become the next current hole cover 4, and the push rod 8 stops moving when it is pressed against the mounting plate 7. The operator continues to push the rotating pressure handle 16 toward one side of the ball linear guide 1 with force, pushes the steel ball 11 out of the screw hole of the ball linear guide 1 and continues to move forward. The linear guide hole cover installation and flattening device has a scientific and reasonable structure, is safe and efficient to use, and provides great help to people.
