Abstract
The utility model provides a special auxiliary tool which is widely used to disassemble all kinds of disks, flanges, gears, bearings and belt pulleys etc., the utility model adopts a thrust bearing device, a thrust bearing is installed on a screw, a centre is installed on the other side of the bearing, the centre and the screw can rotate at random therebetween to make the former sliding friction mode between the top of the screw and workpieces become the rolling friction mode, which can reduce friction greatly, furthermore the utility model can achieve saving labor, reduce labor intensity greatly, operate conveniently, save time and labor, enhance the production efficiency greatly.
Description
The utility model relates to one of specific purpose tool normal in the flight-line maintenance process.
Drawing horse is purposes one of instrument more widely in the flight-line maintenance industry, existingly draws horse generally to adopt its push rod head circular cone directly to head in the centre bore that is drawn object institute noncoupled axle, the pulling of the object that rotating screw bolt is realized.
Having now draws horse in use to have following defective: 1. be sliding friction between push rod conical head surface and the centre bore surface, frictional force is very big, the rotating screw bolt effort; 2. easily cause the screw rod vertex of a cone and the damage of axle centre bore two circular cone rubbing surfaces, very the person draws horse to scrap or makes a centre bore ineffective because of serious wear makes.And centre bore is the camber that is used for measuring axle, the important anchor point of beating and repairing of axle, therefore also makes the reparation of axle increase difficulty.Thereby in the machine repair procedures, press for a kind of not only durable laborsaving, but also easy damaged axle centre bore specific purpose tool not.
The purpose of this utility model just is, draws horse to be improved to existing, and a kind of novel horse of drawing is provided.
The purpose of this utility model is to realize like this.Drawing horse conch bar 1 middle or head installed thrust bearing arrangement 3, movable head (top) 4 is bumped into thrust bearing 3, with trivial jack panel thrust bearing is fixed again.
Accompanying drawing 1 is the novel structural representation that draws horse that the utility model proposes.
Describe the utility model-novel concrete structure that draws horse in detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the structural representation of embodiment.At first thrust bearing device 3 is welded in and draws in the middle of the horse conch bar, during use movable head 4 centerings are drawn the centre bore of object place axle, adjust pulling claw, rotating screw bolt, carry out work.
Outstanding characteristics of the present utility model and advantage are:
1, easy to process need of manufacturing are welded in thrust bearing device to have now and draw the horse conch club head to use.
2, laborsaving owing to adopted thrust bearing, make original sliding friction mode become the rolling friction mode, frictional force is reduced greatly, thereby reach the labour-saving purpose, labour intensity reduces greatly.
3, safety durable has been eliminated because of sliding friction causes and has been drawn the possibility that horse conch masthead point damages or the axle centre bore lost efficacy.
Claims (1)
