Abstract

The utility model discloses a synchronous section bar clamping mechanism which comprises a guiding seat, a clamp capable of performing linear reciprocating motion on the guiding seat and an air cylinder driving the clamp to act. The clamp comprises a left clamp and a right clamp which are oppositely arranged in a matched mode. Sliding seats are arranged under the left clamp and the right clamp and include a left sliding seat and a right sliding seat, parallel racks extending towards each other are respectively arranged on the left sliding seat and the right sliding seat and are respectively a left rack and a right rack. A gear is arranged on the guiding seat, arranged between the left rack and the right rack and meanwhile meshed with the left rack and the right rack. A driving rod of the air cylinder is connected with the outer side of the left sliding seat or the right sliding seat. The air cylinder drives the racks on the sliding seats, the racks push to gear to rotate, and the gear drives the other rack to perform synchronous reverse motion and accordingly achieves synchronous clamping and synchronous loosening. The synchronous section bar clamping mechanism has the advantages of being simple in structure, easy to manufacture, convenient to assemble, low in cost and capable of achieving synchronous clamp actions by using one air cylinder.

Description

The synchronous clamping device of section bar
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of synchronous clamping device of carrying section bar to expect sawing station.
Background technology
In section bar sawing process, because section bar is longer, Saw of section bar need to be cut into some sections, make it meet use length.When sawing device carries out sawing to section bar, need to deliver to sawing station by clamping section bar with the feed mechanism of clamp mechanism, after sawing completes, then unclamp clamp mechanism and reset, after each sawing, need again to clamp section bar and send a defective material, feeding is until cut into whole piece Saw of section bar so repeatedly.
The method of clamping of traditional section bar clamp mechanism is monolateral action, and the stiff end of its fixture maintains static, and movable end drives its action by actuating units such as cylinders, and clamping and unclamping is all by the monolateral action of movable end.This monolateral section bar clamp mechanism exists in sawing reseting procedure, easily occurs that scratch section bar produces burr, makes section bar produce the phenomenons such as distortion, affects outward appearance and the length accuracy of product; In feeding process, answer back to sometimes the fixture at sawing position, make section material section distortion, even can hit pine, break fixture, cause material folding not clamping, loss saw blade, causes saw blade not to be durable, also may quick-fried saw blade, there is potential safety hazard.
Summary of the invention
The defect that the utility model exists for above-mentioned monolateral section bar clamp mechanism, and a kind of safe and reliable section bar clamp mechanism is provided.
For achieving the above object, the scheme that the utility model is taked is: the synchronous clamping device of a kind of section bar, comprises guide holder, can do the fixture of straight reciprocating motion and the cylinder that drives fixture action at guide holder; Fixture comprises left clamp and the right clamp that coupling arranges in opposite directions; It is characterized in that: left clamp and right clamp below are equipped with sliding seat, correspond to respectively left sliding seat and right sliding seat, are respectively provided with the parallel rack extending to the other side mutually on left sliding seat and right sliding seat, correspond to respectively left tooth bar and right tooth bar; On guide holder, establish gear, this gear is located between left tooth bar and right tooth bar and simultaneously and is meshed with left tooth bar and right tooth bar; The drive rod of cylinder is connected to the outside of left sliding seat or right sliding seat.
As further illustrating of technique scheme, described guide holder is U-shaped structure, guide holder the right and left is for supporting limit, between left support limit and right support limit, be provided with two parallel guide rods, left sliding seat and right sliding seat are set on guide rod slidably, described cylinder is located at and is supported outside, limit, and the drive rod of cylinder is through supporting that limit is fixedly connected with sliding seat.
Two tooth bars are separately fixed on two sliding seats, between tooth bar, by gear, mesh, one of them sliding seat is by the effect of air cylinder driven power, drive is fixed on the tooth bar on sliding seat, this tooth bar promotes gear and rotates, and another rack synchronous counter motion of gear driven, thereby realize synchronous clamping, synchronously unclamp.
Or described guide holder is provided with two parallel dovetail slide rails, left sliding seat and right sliding seat bottom are equipped with dovetail groove and pass through dovetail groove slidably on dovetail slide rail.
As further illustrating again of technique scheme, described left clamp and right clamp are that opening level V-arrangement folder is in opposite directions right.
As the improvement of technique scheme, described V-arrangement folder is to being two groups, and these two groups of V-arrangement folders are fixed on sliding seat certain spacing that staggers.
Scheme is known from the above mentioned, the utility model has the advantages that: simple in structure, easily manufacture, easy to assembly, cost is low, only with a cylinder, just can realize fixture synchronization action, thereby avoids in the process of clamping section, crushing section bar, scratch Surface of profile, hit pine and break fixture.
