Description
Technical field
The utility model is related to cylinder technical fields, refer in particular to a kind of high accuracy positioning cylinder.
Background technology
Cylinder generally includes cylinder body, piston and piston rod, and piston can move back and forth in cylinder body, and cylinder body is divided by piston
Two chambers drive movement of the piston in inner chamber of cylinder block by adjusting the pressure differential of two chambers.Since piston rod is in work
Make in motion process, generally push load (workpiece) carry out straight reciprocating, therefore piston rod its in moving process
It is easy to generate deformation, piston rod is caused to stretch and is obstructed, and cause piston rod positioning inaccurate, so as to influence determining for positioning cylinder
Bit function, for the piston rod of big stroke, straightness of the piston rod during stretching operation just seems very heavy
It will.
Invention content
For the deficiency for having technology, the utility model provides a kind of high accuracy positioning cylinder, which can protect
The piston rod demonstrate,proved in it does not shake during telescopic moving, can realize positioning function to exactly.
To achieve the above object, technical solution provided by the utility model is：A kind of high accuracy positioning cylinder, including cylinder
Body, is done the piston rod of stretching motion by piston drives edge inner chamber of cylinder block and is installed respectively the piston in inner chamber of cylinder block
Protecgulum and rear cover on cylinder body rear and front end have further included copper sheathing, and the copper sheathing is arranged between the piston rod and protecgulum,
Wherein described copper sheathing inner wall is slidably connected with piston rod composition, forms guide support effect.
Further, the spacer being sleeved on the piston rod outer end face is further included.
Further, the spacer its close on and be also equipped with rubber material on the one end on the piston rod top and be made
Bumper.
Further, the cylinder body is additionally provided with the adjustable mounting hole being finely adjusted for installation site thereon.
Compared with prior art, this programme is used and is determined by what cylinder body, piston, piston rod, protecgulum, rear cover and copper sheathing formed
Position cylinder structure, by mutual effective cooperation between piston rod, piston, protecgulum and copper sheathing and high manufacturing accuracy, to protect
Demonstrate,prove piston rod has excellent positioning performance during stretching motion, and shaking will not be generated during running fix, ensures
The accurate and reliability of positioning；In addition this programme can be made also by being set with spacer in piston rod periphery by being set with spacer
Positional cylinder is obtained in practical work process according to stroke needs, selects the spacer of appropriate length to ensure that it is suitable that piston rod has
Movement travel.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
The utility model be directed to piston rod of the existing positional cylinder in it exist during telescopic moving shake and then
The problem of guide-localization is inaccurate, and a kind of high accuracy positioning cylinder proposed, can ensure the piston in it using the positional cylinder
Bar does not shake during telescopic moving, can realize positioning function to exactly.
Referring to shown in attached drawing 1 to 4, the present embodiment provides a kind of high accuracy positioning cylinder, which includes cylinder body 1, installation
Piston 5 in 1 inner cavity of cylinder body is done the piston rod 4 of stretching motion by 5 drives edge cylinder body of piston, 1 inner cavity and is separately mounted to
Protecgulum 2 and rear cover 6 on 1 rear and front end of cylinder body.In order to during the work time can be to being in the piston rod 4 of stretching motion state
Guide support effect is formed, the present embodiment is also equipped with copper sheathing 3 between piston rod 4 and protecgulum 2.Piston rod 4 its movement stretch
During contracting, piston rod 4 forms linear slide with 3 inner wall of copper sheathing and connect.It is understood that in order to have to piston rod 4
Certain support function, copper sheathing 3 its length in the present embodiment can extend as possible, to increase being bonded for copper sheathing 3 and piston rod 4
Area so that copper sheathing 3 has piston rod 4 certain support function.It should be noted why the present embodiment uses
The copper sheathing structure being made of copper material, mainly in view of copper material itself wearability preferably and its material of copper material into
This is relatively low, and the tube-in-tube structure of the composition of other materials may be used during actual fabrication.
Positional cylinder in the present embodiment is also equipped with spacer 7 in it, spacer 7 its be mainly used for row to adjust piston rod 4
Journey.Specifically, be exactly by being set with spacer 7 in 4 periphery of piston rod, piston rod 4 its during stretching is displaced outwardly,
It is contacted with keeping out for protecgulum 2 by spacer 7, continues to move forward so as to limit piston rod 4.On this basis, in order to avoid spacer 7
Directly be in contact (due to spacer 7, its general making material is harder, and impact force is larger when being in contact with other objects) with protecgulum 2,
Has certain buffer capacity, the present embodiment is equipped on the front end face (end face being in contact with protecgulum 2) of spacer 7 by rubber
The bumper 8 that glue material matter is made.During actual fabrication, other materials with cushion performance can also be used to make
It forms.
Referring to shown in attached drawing 5, the present embodiment is provided with for the ease of the installation of entire positional cylinder on the both sides of cylinder body 1
For finely tuning the adjustable mounting hole 9 of installation site, this is adjustable mounting hole 9 can be made using the waist type structure of mounting hole of strip
The screw being mounted in the adjustable mounting hole 9 is obtained to be finely adjusted along its length.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore the variation that all shape, principles according to the utility model are made, should all cover in the scope of protection of the utility model
It is interior.
