Description
Technical field
The present invention relates to field of machining, and in particular to roller gear turning clamp.
Background technology
Gear drive is a kind of mechanically operated primary drive form.The height of the accuracy of gear decides mechanically operated essence
True property and stationarity.In Gear Processing.An important factor for manufacture, cooperation and the installation accuracy of fixture are the influence accuracies of gear,
Clamping apparatus for gear wheel processing it is whether reasonable in design, be not only related to the precision of gear, be also related to the efficiency of Gear Processing.For
This, formulates rational fixture according to the structure and process characteristic of gear and just seems quite important.
After roller gear garland key, carry out smart car gear blank frequently with conical core shaft, can using two endoporus of conical core shaft tensioner
So that the axiality of workpiece reference for assembling and machining benchmark is effectively ensured, and good end standard is provided for later process, but made
With needed during conical core shaft on anvil iron by workpiece pier it is real, clamp, not only work efficiency is low, labor intensity is big but also easy damaged workpiece
Endoporus and " ablation " mandrel, cause positioning precision to decline, plus mandrel two it is top on positioning rigidity it is poor, therefore process gear blank
When end face and circular runout it is larger, so as to influence following process.
The content of the invention
In order to solve the above problems, present invention offer is a kind of simple in construction, steps up reliable, it is ensured that machining accuracy, reduce
The roller gear turning clamp of labor strength.
Roller gear turning clamp of the present invention, including be located by connecting set and push rod, the set that is located by connecting are raised in step
Shape, the center are provided with a step through-hole, are located by connecting in the through hole of set bottom and are provided with a positioning disk, the positioning disk is with setting
Put and be connected in the pull bar being located by connecting in set upper through-hole, the rod outer sleeve is connected to a tensioner body for carrying boss, described to rise
Tight body is connected by screw with the boss for the set that is located by connecting, the one arch back-up ring of outside socket of the tensioner body boss, the bow
Shape back-up ring is connected by being arranged on the sunk screw outside arch back-up ring on eaves with tensioner body phase, and an expansion sleeve, institute are provided with pull bar
State push rod one end to offset with expansion sleeve, the other end is fixedly linked with positioning disk.
Preferably, pull bar is socketed with one close to one end of tensioner body and pushes away circle.
Preferably, pull bar end has been bolted a pressing plate.
Preferably, pull bar stretches out tensioner body end in coniform.
Preferably, the taper that pull bar stretches out tensioner body end is 1：20.
The present invention is simple in construction, steps up reliable, it is ensured that machining accuracy, reduce labor strength.
Brief description of the drawings
Fig. 1 is the structural representation of roller gear turning clamp.
Reference：1- positioning disks, 2- are located by connecting set, 3- tensioner bodies, 4- screws, 5- push rods, 6- back-up rings, 7- pull bars,
8- expansion sleeves, 9- push away circle, 10- sunk screws, 11- pressing plates, 12- workpiece.
Embodiment
Roller gear turning clamp, including be located by connecting set 2 and push rod 5, the set 2 that is located by connecting is in step convex,
The center is provided with a step through-hole, is located by connecting in the through hole of 2 bottoms of set and is provided with a positioning disk 1, the positioning disk 1 is with setting
Put and be connected in the pull bar 7 being located by connecting in 2 upper through-holes of set, a tensioner body 3 for carrying boss, institute are socketed with outside the pull bar 7
State tensioner body 3 by screw 4 with the boss for the set 2 that is located by connecting to be connected, the one arch back-up ring of outside socket of the boss of tensioner body 3
6, the arch back-up ring 6 is connected by the sunk screw 10 being arranged on 6 outer eaves of arch back-up ring with tensioner body 3, is set on pull bar 7
There is an expansion sleeve 8, described one end of push rod 5 offsets with expansion sleeve 8, and the other end is fixedly linked with positioning disk 1.Pull bar 7 is close to tensioner
One end of body 3 is socketed with one and pushes away circle 9.The end of pull bar 7 is connected with a pressing plate 11 by bolt 4.Pull bar 7 stretches out the end of tensioner body 3
It is coniform, and taper is 1：20.
The fixture utilizes Driven by Hydraulic Cylinder pull bar, and when pull bar 7 is moved to the left, the circular conical surface of ringfeder body 3 forces elastic expanding
Set outwards struts, so as to the endoporus of tensioner workpiece 12；When pull bar moves right, push rod 5 ejects ringfeder, and ringfeder is retracted, and takes out workpiece
12.The machining accuracy of workpiece 12 had so both been ensure that, has made clamping reliable rapidly again.
