Description

The rotation clamping device of fully automatic cutting machine bed

Technical field

The utility model is related to cutting equipment field, more particularly to a kind of rotation clamping device of fully automatic cutting machine bed.

Background technology

It is very frequent in the use of auto parts and components manufacturing enterprise, cutting machine, there are hand-powered cutter and automatic gas cutting machine, It can meet production needs using hand-powered cutter when yield can reach requirement and save purchase automatic gas cutting machine Cost, but when output demand is higher, hand-powered cutter is just unable to meet production needs, especially in cutting accuracy On, the precision of manual cutting is relatively low, is unable to reach the requirement of modern production.And the rotation of fully automatic cutting machine bed in the prior art It is that cutting is inaccurate to turn clamping device not, is exactly complicated for operation, and working efficiency is low, causes a portion of these defects former Because being because the feeder structure of fully automatic cutting machine bed is unreasonable, working efficiency is low.

Utility model content

Purpose of utility model：For problems of the prior art, the utility model provides a kind of fully automatic cutting machine The rotation clamping device of bed, can not only be accurately positioned and be clamped to workpiece, and is easy to operate, work efficiency is high.

Technical solution：The utility model provides a kind of rotation clamping device of fully automatic cutting machine bed, including level is set The workbench and pedestal set, the pedestal are fixed on the workbench, further include elastic handgrip, swingle, telescopic, rotation The end of driving mechanism and telescopic driving mechanism, the elasticity handgrip is fixed on the front end of the swingle and coaxially sets It sets, the swingle is driven by the rotary drive mechanism to be rotated；The telescopic is sleeved on the swingle periphery, described to stretch Contracting set driving mechanism drives the telescopic to be slid back and forth along the swingle.

Further, the rotary drive mechanism is made of motor, shaft, driving gear and driven gear, the motor It is rotatablely connected by the shaft and the driving gear, the driving gear is engaged with the driven gear, the driven tooth Fixing sleeve is taken turns on the lateral wall of the swingle.After electric motor starting, driving gear rotation is driven by shaft, to driven tooth Wheel rotation drives swingle rotation, the rotation band dynamic elasticity handgrip of swingle to rotate.

Further, the telescopic driving mechanism is made of pull rod and the 5th cylinder, the front end of the pull rod with it is described Base rotation connects, and middle part is rotatablely connected with the telescopic, and end and the telescopic end of the 5th cylinder are rotatablely connected, described The fixing end of 5th cylinder is fixedly connected with the pedestal.By the end of pull rod, in the telescopic drive pull rod of the 5th cylinder Portion is rotated around telescopic, and around base rotation, the middle part of such pull rod and the connection bolt of telescopic being capable of bands for the front end of pull rod Dynamic telescopic slides back and forth along swingle, and when sliding into the front end of swingle, there are one from four to elastic handgrip for telescopic The extruding force at circumferential center forces elastic handgrip to shrink, to realize firmly grasping to the workpiece in elastic handgrip；It is revolved when sliding into When the least significant end of bull stick, above-mentioned extruding force disappears, and elastic handgrip is restored to open configuration again, to unclamp its internal work Part.

Further, the open end of the elastic handgrip is made of multiple shrapnels of circle distribution, and end is conus elasticus Platform structure, the heavy caliber end of the circular cone structure and each shrapnel seamless connection, small-caliber end and the seamless rank of the swingle It connects.At circular cone structure, open end is designed to be made of a plurality of circumferentially spaced shrapnel the tip designs of elastic handgrip, when flexible When set is moved forward along swingle, telescopic applies an extruding from the four circumferential centers of circle to the circular cone structure of elastic handgrip Power, this extruding force make multiple shrapnels of elastic handgrip also be shunk from the four circumferential centers of circle, and this makes it possible to be placed in shrapnel Workpiece clamping to be cut, the location of workpiece is unstable when preventing from subsequently cutting, and influences cutting accuracy.

Advantageous effect：In the utility model, after workpiece to be cut is put into elastic handgrip, start telescopic driving machine Structure drives telescopic to be moved to close to the direction of elastic handgrip, and after the elastic handgrip of end extruding of telescopic, elastic handgrip is shunk By Workpiece clamping to be cut, starts rotary drive mechanism and drive swingle high speed rotation, the high speed rotation band dynamic elasticity of swingle Then cutter are moved in the open end of elastic handgrip and are contacted with workpiece to be cut by the high speed rotation of handgrip, cutter Blade contacts the cutting that can be realized as treating cutting workpiece with high-speed rotating workpiece to be cut in elastic handgrip；Cutting finishes Afterwards, cutter are removed, is then moved telescopic to one end far from elastic handgrip along swingle by telescopic driving mechanism Dynamic, elastic handgrip opens, and elastic handgrip is still in high speed rotation at this time, so the work that the elastic handgrip opened can finish cutting Part pops up while unclamping, and finally closes rotary drive mechanism, and swingle stops rotating, i.e., elastic handgrip also stops rotating, The cutting process of one workpiece terminates.As it can be seen that in this equipment, the clamping action of telescopic can ensure elastic handgrip to be cut The clamping and positioning of workpiece, high-speed rotating elasticity handgrip are used cooperatively with opposing stationary cutter, the workpiece being cut into Accurate size, and this equipment operation is convenient, and clamping and positioning effect is good, and working efficiency is higher.
