Abstract
The utility model relates to a multipoint clamping mechanism which comprises a workbench, a main clamp oil cylinder, a main movable clamp, a fixed clamp, an upper clamp and an upper clamp oil cylinder. The fixed clamp is fixedly connected above the workbench. The main movable clamp is in guidance connection with the workbench and disposed opposite to the fixed clamp. The upper clamp is located above a position between the main movable clamp and the fixed clamp. The rod end of the main clamp oil cylinder is in transmission connection with the main movable clamp. The rod end of the upper clamp oil cylinder is in transmission connection with the upper clamp. The multipoint clamping mechanism has the advantages that the mechanism is simple in structure, firm in clamping and convenient to use; workpieces are clamped in a multi-direction and multipoint way, the contact surface of the clamps and the workpieces is large, and the problems that the workpieces cannot be clamped firmly and are prone to rotation in traditional one-way clamping are solved; the mechanism is highly universal for the shapes of the workpieces, and both circular tubes and rectangular tubes can be firmly clamped; saw blade damage caused by infirm workpiece clamping in the prior art is avoided.
Description
Technical field
The utility model relates to a kind of frock clamp, particularly a kind of multipoint clamping mechanism.
Background technology
Along with the future development of Modern Manufacturing Industry towards efficient, high accuracy and economy, the starting point of processing is cut in sawing machine sawing as gold, become integral link important in part process.Sawing can save material, reduces secondary operations amount and enhance productivity, thus sawing machine particularly automation sawing machine be widely used in the national economy every field such as iron and steel, machinery, automobile, shipbuilding, oil, mine and Aero-Space.Sawing machine comprises clamp for sawing machine, clamp for sawing machine of the prior art comprises positioning fixture and feed clamp, for holding workpiece, to locate the positioning fixture of processing, be arranged on sawing machine lathe bed upper end, sawing machine lathe bed rear side is provided with feeding and drives bed, feed clamp is arranged on feeding and drives bed upper end, positioning fixture consists of fixed clamp plate and movable grip block, movable grip block completes and the laminating of fixed clamp plate or separated by external driver device, its weak point is: the one, because positioning fixture adopts one-sided clamping force holding workpiece, its chucking power is less, cannot firmly clamp workpiece, the 2nd, be that feed clamp holding workpiece is unreliable, easily occur skidding off feed clamp clamping zone, and the phenomenon of spinning easily appears in workpiece, thereby the saw blade causing damages.
Summary of the invention
The purpose of this utility model is exactly for fear of the weak point in background technology, and a kind of multipoint clamping mechanism is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of multipoint clamping mechanism, comprise workbench, main folder oil cylinder, active clamp, clamp pincers, upper clamp, upper folder oil cylinder, clamp pincers are fixedly connected on workbench top, initiatively clamp is connected with workbench guiding and is oppositely arranged with clamp pincers, upper clamp is above between active clamp and clamp pincers, and the rod end of described actuating cylinder is in transmission connection in active clamp, and the rod end of upper folder oil cylinder is in transmission connection in upper clamp.
For a kind of optimization of the present utility model, on workbench, be equipped with respectively left holder, right holder, be placed on the built-in beam between left holder and right holder, described active clamp is placed in left holder, clamp pincers are placed in right holder, upper clamp is placed in built-in beam below, the cylinder body of described main folder oil cylinder is connected with left holder, and the cylinder body of upper folder oil cylinder is connected with built-in beam.
The utility model is compared with background technology, has simple in structurely, and clamping firmly, easy to use; By multi-direction, multipoint system holding workpiece, the contact-making surface of clamp and workpiece is larger, efficiently solves the not clamping of traditional one direction clamping, the phenomenon that workpiece easily spins; Profile versatility to workpiece is stronger, no matter be to pipe or rectangular tube, and can firm grip; Avoided in the past because piece-holder is insecure, and the phenomenon that the saw blade causing damages.
Accompanying drawing explanation
The perspective view of Tu1Shi multipoint clamping mechanism.
Tu2Shi multipoint clamping mechanism dislikes structural representation.
The specific embodiment
Embodiment 1: with reference to Fig. 1 and 2.A kind of multipoint clamping mechanism, comprise workbench 1, main folder oil cylinder 2, active clamp 5, clamp pincers 10, upper clamp 7, upper folder oil cylinder 6, clamp pincers 10 are fixedly connected on workbench 1 top, initiatively clamp 5 is connected with workbench 1 guiding and is oppositely arranged with clamp pincers 10, upper clamp 7 is above between active clamp 5 and clamp pincers 10, the rod end of described actuating cylinder 2 is in transmission connection in active clamp 5, and the rod end of upper folder oil cylinder 6 is in transmission connection in upper clamp 7.On workbench 1, be equipped with respectively left holder 4, right holder 9, be placed on the built-in beam 8 between left holder 4 and right holder 9, described active clamp 5 is placed in left holder 4, clamp pincers 10 are placed in right holder 9, upper clamp 7 is placed in built-in beam 8 belows, the cylinder body of described main folder oil cylinder 2 is connected with left holder 4, and the cylinder body of upper folder oil cylinder 6 is connected with built-in beam 8.
It is to be understood that: although the present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation, all fall in protection domain of the present utility model.
