Anti-falling bolt for machine tool

Abstract

The invention discloses an anti-falling bolt for a machine tool. The anti-falling bolt comprises a base, extension blocks, a screw rod, a nut, a fixer and a rotary screw rod. The screw rod is welded at a top of the base. The nut in threaded connection is arranged at the top of the screw rod. The base is designed in a hollow state. A sliding groove is arranged in the base. The sliding groove penetrates through the base. There are two extension blocks, the two extension blocks are symmetrically installed in the sliding groove. The extension blocks are connected with a connecting rod through a shaft. The other end of the connecting rod is connected with a lifting lug shaft on a transmission sliding block. The transmission sliding block is in threaded connection with a rotating screw rod. Therotating screw rod extends to an outer side of the base. The rotating screw rod is rotated to drive the transmission sliding block to move so as to achieve contraction and extension of the extension blocks, a fixator is installed at a position, close to an outer edge, of the base, and the extension blocks is fixed through the fixator. The design is reasonable; and the extension blocks can change alength of the base according to conditions so as to adapt to different requirements.

Description

technical field [0001] The invention relates to an anti-falling bolt for a machine tool, which belongs to the field of machinery. Background technique [0002] Bolts are often used in the production of industrial machinery and equipment. For example, T-slot bolts play an important role in machine tools. T-slot bolts are used in occasions where only the nuts are loosened without removing the bolts, so that the connected parts come out or loosen. , and the existing T-slot bolts have the following defects: the fixed size cannot be changed according to the situation, and a certain vibration will be generated during the operation of the machine tool, and the long-term vibration will cause the nut to rotate and fall off, which cannot adapt to industrial production. need. Contents of the invention [0003] The object of the present invention is to provide an anti-falling bolt for machine tools to solve the above technical problems. [0004] To achieve the above object, the pres...
