technical field

The utility model relates to the technical field of flat-nose pliers, in particular to an anti-shake and anti-shock mobile flat-nose pliers.

Background technique

Flat-nose vise, also known as machine vise, is a general-purpose fixture that is often used to install small workpieces. It is a random accessory for milling machines and drilling machines. It is fixed on the machine table to clamp the workpiece for cutting. The assembly structure of the flat-nose pliers is detachable threaded connection and pin connection; the linear motion of the movable pliers body is transformed by the helical motion; the working surface is the friction surface of the screw pair, the guide rail pair and the clearance fit shaft and hole. Flat-nose pliers are simple in composition and compact in structure.

When the existing milling machine and drilling machine process the workpiece, it is necessary to use the flat-nose pliers on the machine tool to fix the workpiece. Therefore, it is easy to cause the screw of the flat-nose pliers to rotate due to its own vibration, which in turn causes the unsteady fixation of the workpiece, which affects the processing of the workpiece by the lathe. Therefore, we propose an anti-shake, anti-shock Mobile flat-nose pliers to solve the problems raised above.

Utility model content

The purpose of this utility model is to solve the problem that the existing lathe in the prior art will generate large vibration when processing the workpiece, so it is easy to cause the screw of the flat jaw to rotate due to its own vibration, thereby causing the workpiece to be not firmly fixed. The situation affects the shortcomings of the lathe's processing of the workpiece, and a kind of anti-shake and anti-shock mobile flat-nose pliers is proposed.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
