Description

Locking screw for machine tool foot margin

Technical Field

The utility model relates to the technical field of anti-loosening screws, in particular to a machine tool foot anti-loosening screw.

Background

The existing looseness prevention of the foundation leveling screw of the machine tool structure uses a common carbon steel or stainless steel flat-end jackscrew, but due to the material hardness problem of the two jackscrews, the excircle thread of the adjusting screw is often damaged, and the later-stage rotation of the adjusting screw is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a locking screw for a machine tool foundation, and aims to solve the problems that in the prior art, the locking of a machine tool structure foundation leveling screw is realized by using common carbon steel or stainless steel flat-end jackscrews, but due to the hardness of the materials of the two jackscrews, the excircle threads of an adjusting screw are often damaged, and the later-stage rotation of the adjusting screw is influenced.

In order to achieve the purpose, the utility model adopts the following technical scheme: the machine tool foot anti-loosening screw comprises an adjusting screw in threaded connection with the bottom end of a machine tool body, a machine tool gasket is arranged on the lower portion of the adjusting screw, a threaded hole is formed in the side face of the machine tool body, the anti-loosening screw is in threaded connection with the inner thread of the threaded hole, the anti-loosening screw comprises a screw body in threaded connection with the threaded hole and a protective copper pad in threaded connection with the screw body, and the protective copper pad is in contact with the adjusting screw.

According to a further technical scheme, the protective copper pad is made of red copper.

According to a further technical scheme, the tail of the screw body is provided with a hexagonal wrench position.

According to a further technical scheme, the screw body is provided with a threaded hole, and the protective copper pad is provided with an external threaded part which is in matched connection with the threaded hole.

According to a further technical scheme, the machine tool gasket is made of iron.

According to a further technical scheme, the cross section of the protective copper pad is in a T shape.

According to a further technical scheme, the screw body is a countersunk head screw.

The utility model has the beneficial effects that: the outer circle threads of the screw body and the adjusting screw are spaced by the protective copper pads, and due to the material characteristics of copper materials, the screw body is softer relative to the adjusting screw threads and the locking screw, so that the outer circle of the adjusting screw can be effectively protected, the threads of the adjusting screw are prevented from being damaged, and a good locking effect can be achieved.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1-3, a locking screw for machine tool anchor comprises an adjusting screw 2 in threaded connection with the bottom end of a machine tool body 1, wherein a machine tool gasket 4 is arranged on the lower portion of the adjusting screw 2, preferably, the machine tool gasket 4 is made of iron, a threaded hole is formed in the side surface of the machine tool body 1, a locking screw 3 is in threaded connection with the threaded hole, the locking screw 3 comprises a screw body 31 in threaded connection with the threaded hole and a protective copper pad 32 in threaded connection with the screw body 31, preferably, the protective copper pad 32 is made of red copper, and the protective copper pad 32 is in contact with the adjusting screw 31.

In the utility model, the screw body 31 and the excircle threads of the adjusting screw 2 are spaced by the protective copper pads 32, and due to the material property of copper, the screw body 31 is softer than the threads of the adjusting screw 2 and the anti-loosening screw 3, so that the excircle of the adjusting screw 2 can be effectively protected, the threads of the adjusting screw 2 are prevented from being damaged, and a good anti-loosening effect can be achieved.

In a specific embodiment of the present invention, the screw body 31 has a hexagonal wrench position at the tail, and when the locking screw 3 needs to be tightened or disassembled, the hexagonal wrench is manually inserted into the hexagonal wrench position at the tail of the screw body 31, so that the locking screw 3 can be conveniently tightened or disassembled, and the operation is convenient.

In an embodiment of the present invention, the screw body 31 is provided with a threaded hole, and the protective copper pad 32 is provided with an external threaded portion in matching connection with the threaded hole.

In an embodiment of the present invention, the cross-sectional shape of the protection copper pad 32 is a T-shape.

In an embodiment of the present invention, the screw body 31 is a countersunk head screw.
