Description
Technical field
The present invention relates to field of machining, be specifically related to roller gear turning clamp.
Background technology
Gear drive is mechanically operated a kind of primary drive form.The height of the accuracy of gear decides mechanically operated accuracy and stationarity.In Gear Processing.The manufacture of fixture, cooperation and installation accuracy are the key factors affecting the accuracy of gear, clamping apparatus for gear wheel processing whether reasonable in design, are not only related to the precision of gear, have also been related to the efficiency of Gear Processing.For this reason, formulate rational fixture according to the Structure and energy feature of gear and just seem quite important.
After roller gear garland key, normal employing conical core shaft carrys out finish turning tooth base, utilize conical core shaft tensioner two endoporus, effectively can ensure the axiality of workpiece reference for assembling and machining benchmark, and provide good end standard for later process, but need on anvil iron workpiece pier is real when using conical core shaft, clamping, not only work efficiency is low, labour intensity is large, and easy damaged inner hole of workpiece and " ablation " mandrel, positioning precision is caused to decline, add mandrel top two on positioning and rigid poor, therefore process tooth base time end face and circular runout all larger, thus affect following process.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, step up reliable, can machining accuracy be ensured, reducing the roller gear turning clamp of labor strength.
Roller gear turning clamp of the present invention, comprise be located by connecting cover and push rod, the described cover that is located by connecting is in step convex, the center has a step through-hole, a positioning disk is provided with in the through hole be located by connecting bottom overlapping, described positioning disk be arranged on the pull bar overlapped in upper through-hole that is located by connecting and be connected, described rod outer sleeve is connected to one with the tensioner body of boss, described tensioner body is connected with the boss overlapped that is located by connecting by screw, the outside of described tensioner body boss is socketed an arc back-up ring, described arc back-up ring is connected with tensioner body by the sunk screw be arranged on the outer eaves of arc back-up ring, pull bar is provided with an expansion sleeve, described push rod one end and expansion sleeve offset, the other end and positioning disk are fixedly linked.
Preferably, pull bar is socketed with one near 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 is coniform.
Preferably, pull bar stretches out the tapering of tensioner body end is 1:20.
Structure of the present invention is simple, steps up reliable, can ensure machining accuracy, reduce labor strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of roller gear turning clamp.
Reference numeral: 1-positioning disk, 2-is located by connecting cover, and 3-tensioner body, 4-screw, 5-push rod, 6-back-up ring, 7-pull bar, 8-expansion sleeve, 9-pushes away circle, 10-sunk screw, 11-pressing plate, 12-workpiece.
Detailed description of the invention
Roller gear turning clamp, comprise be located by connecting cover 2 and push rod 5, the described cover 2 that is located by connecting is in step convex, the center has a step through-hole, a positioning disk 1 is provided with in the through hole be located by connecting bottom cover 2, described positioning disk 1 be arranged on the pull bar 7 be located by connecting in cover 2 upper through-hole and be connected, one is socketed with the tensioner body 3 of boss outside described pull bar 7, described tensioner body 3 is connected by the boss of screw 4 with the cover 2 that is located by connecting, the outside of described tensioner body 3 boss is socketed an arc back-up ring 6, described arc back-up ring 6 is connected with tensioner body 3 by the sunk screw 10 be arranged on the outer eaves of arc back-up ring 6, pull bar 7 is provided with an expansion sleeve 8, described push rod 5 one end and expansion sleeve 8 offset, the other end and positioning disk 1 are fixedly linked.Pull bar 7 is socketed with one near one end of tensioner body 3 and pushes away circle 9.Pull bar 7 end is connected with a pressing plate 11 by bolt 4.It is coniform that pull bar 7 stretches out tensioner body 3 end, and tapering is 1:20.
This fixture utilizes Driven by Hydraulic Cylinder pull bar, and when pull bar 7 is moved to the left, the taper seat of ringfeder body 3 forces elastic expansion-sleeve outwards to strut, thus tensioner workpiece 12 endoporus; When pull bar moves right, push rod 5 ejects ringfeder, and ringfeder is retracted, and takes out workpiece 12.So both ensure that the machining accuracy of workpiece 12, make again clamping reliable rapidly.
