Embodiment 1

[0018] Such as figure 1 As shown, this embodiment includes a clamping unit, a slideway 4 and a frame 1, the slideway 4 and the clamping unit are placed on the frame 1, the clamping unit includes a movable plate 3 and a fixed plate 2, and the movable plate 3 slides Set on the slideway 4, the fixed plate 2 is set on the frame 1, and also includes a driving mechanism and a positioning mechanism, the driving mechanism is connected to the bottom of the movable plate 3, and the positioning mechanism is arranged in parallel with the clamping unit. On the frame 1, the movable plate 3 and the fixed plate 2 constitute a clamping unit that can change the clamping gap according to the shape and size of the rod material. The fixed plate 2 provided can limit the rod material, and the movable plate 3 can Under the push of the driving mechanism, it advances and retreats quickly to clamp or loosen the rod material; during the material cutting process, the rod material is close to the inner wal...

Embodiment 2

[0020] Such as figure 1 As shown, the present embodiment is based on Embodiment 1. The driving mechanism includes a hydraulic cylinder 6 and a hydraulic motor. The hydraulic cylinder 6 is arranged on the same level as the movable plate 3. The slideway 4 is a U-shaped groove, and the hydraulic cylinder outputs One end of the end 5 passing through the U-shaped groove is connected with the bottom end of the movable plate 3 , and the other end of the U-shaped groove is connected with the fixed plate 2 . In view of defects such as unstable clamping of mechanical clamping and easy noise generation of pneumatic clamping, on the same horizontal plane, the hydraulic motor converts hydraulic energy into mechanical energy output, and the output end 5 of the hydraulic cylinder drives the movable plate 3 to maintain a stable and fast speed to achieve reciprocation Linear motion works; the movable plate 3 is slidably arranged on the U-shaped groove, and the opening of the U-shaped groove ca...

Embodiment 3

[0022] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes a plurality of studs arranged on the side of the movable plate 3 facing the fixed plate 2 and a plurality of shockproof feet 7 arranged at the bottom of the frame 1 . During the clamping process, in order to better ensure the clamping efficiency, the studs set on the inner wall of the movable plate 3 can engage the rod material, increase the friction between the movable plate 3 and the rod material, and avoid cutting when the cutting mechanism cuts. Cause the mutual collision between the bar material and the baffle plate; when cutting, a large interaction force will be generated between the cutting mechanism and the bar material, and between the bar material and the frame 1, and the shockproof set at the bottom of the frame 1 The pad 7 can offset the generated interaction force, further protect the clamping mechanism and prolong its service life.

Abstract

The invention discloses a rod clamping mechanism which comprises a clamping unit, a sliding way and a machine frame. The sliding way and the clamping unit are both arranged on the machine frame, the clamping unit comprises a movable plate and a fixed plate, the movable plate is arranged on the sliding way in a sliding mode, and the fixed plate is arranged on the machine frame. The rod clamping mechanism further comprises a driving mechanism and a positioning mechanism, the driving mechanism is connected with the bottom end of the movable plate, and the positioning mechanism and the clamping unit are arranged in parallel. The problems of the instability of traditional mechanical clamping and large noise caused by clamping of a pneumatic clamping mechanism are solved through the adoption of the driving mechanism, the good operating environment is maintained while the clamping reliability is guaranteed, and the working efficiency is improved; due to the arrangement of the positioning mechanism, it is guaranteed that a rod can be kept in the correct movement direction before entering the clamping mechanism, and the rod can further be fixed when being cut, so that large-amplitude vibration of the rod is avoided.

Description

technical field [0001] The invention relates to a clamping device, in particular to a rod material clamping mechanism. Background technique [0002] During the cutting process of the bar material, the position of the guide rail changes or vibrates due to the cutting force, inertial force and other forces, which destroys the original accurate positioning and needs to be clamped and fixed. Traditional clamping devices, such as mechanical clamps Clamping mechanism, pneumatic clamping mechanism, but its transmission force is small, unstable when working, and the bolt-fixed mechanical clamping is easy to cause the vibration of the rod material due to cutting, and the collision with the mechanism will eventually make the clamping loose, and the reliability drops sharply; the most Seriously, the noise generated by the pneumatic clamping mechanism is large, which affects the work efficiency to a large extent. Contents of the invention [0003] The invention solves the problem of ...
