Abstract
The invention discloses an integrated rear cover of an air cylinder. The rear cover comprises a cover body and a piston rod extending outwards along one side of the cover body, wherein the cover body and the piston rod are integrally molded through injection, so that the cover body and the piston rod can have a coaxial effect, processing steps can be reduced, lower working efficiency and cost waste cause by eccentricity, or connection instability and other factors of the cover body and the piston rod due to adoption of other connection ways can be voided, and by means of a detection hole and a drive hole formed in the cover body, whether a suction disc or a holding tool connected with the air cylinder absorbs or holds an object can be detected while a one-time driving function is realized.
Description
Technical field
The present invention relates to a kind of cylinder, especially relate to the cylinder back cover in a kind of cylinder.
Background technology
In industry, conventional cylinder is carrying out the carrying of workpiece, positioning and to drive other devices.Existing cylinder can be installed
To in manipulator jig, coordinate to complete the crawl of product with manipulator jig, existing cylinder mostly is single-action type cylinder, general
Sucker can be installed additional and embrace tool head, and install and transfer block then need to separately be installed additional during sucker on cylinder.Under the promotion of external gas source, inhale
Disk and an armful tool head can only do elastic motion, thus the absorption to product and gripping can only be realized under the drive of mechanical hand,
The function of realizing is more single；And the detection Multi-purpose mechanical switch detection of existing cylinder.And the connection lid of cylinder back cover and work
The connection great majority of stopper rod are using connected modes such as gluing or screw threads.
The applicant has applied for an entitled cylinder, Application No. cn201410289222.x on June 25th, 2014
Patent of invention disclose cylinder back cover, including lid and the piston rod that is fixed on described lid, described lid offers
Drive hole and detection hole, described drive hole runs through described lid, offers and described inspection along its axial direction in described piston rod
The sense channel that gaging hole communicates, described piston rod is fixed on described lid by way of gluing.This cylinder back cover due to
It is by way of gluing, lid to be linked together with piston rod, more time-consuming during processing, if injecting glue is improper easily gluing
Bias or distortion, such cylinder thrust when left linear thrust acts on concentrates certain position not reach the normal effect run of cylinder
Really.
Content of the invention
It is an object of the invention to overcoming the defect of prior art, provide a kind of cylinder disjunctor bonnet, by piston rod with
The integral type injection of lid is made, and to improve the work efficiency of cylinder.
For achieving the above object, the present invention proposes following technical scheme: includes lid and along described lid one epitaxial lateral overgrowth
The piston rod stretched, described lid is concentric circular with the cross section of piston rod, and described lid is integrated injection with described piston rod
Form.
Preferably, the upper end of described lid is provided with a drive hole and detection hole.
Preferably, described drive hole runs through entirely described lid.
Preferably, described piston rod inner is provided with the passage coaxial with described piston rod, and described passage one end is to open
Mouthful, the other end is passed through lid portion inside.
Preferably, described detection hole is attached passing through by a cross-drilled hole vertical with described passage with described passage
Logical.
Preferably, described lid is additionally provided with the first seal groove, for placing sealing ring.
Preferably, described piston rod be provided with the second seal groove with described lid opposite side, for placing sealing ring.
The invention has the beneficial effects as follows: lid and piston rod integrated injection forming, it is possible to reduce tooling step is rapid, and energy
Enough avoid other connected modes so that lid and piston rod decentraction or be connected the factor such as unstable and bring cylinder operation efficiency relatively
The waste of low and cost.

Specific embodiment
Below in conjunction with the accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
In conjunction with Fig. 1, Fig. 2, disclosed cylinder disjunctor bonnet is connected to the end of the cylinder body of cylinder, for closing
Cylinder body and to the cylinder interior Input gas of cylinder thus the motion of driving cylinder internal piston part.Cylinder disjunctor bonnet includes covering
Body 1 and piston rod 2, by way of injection, the parameter that setting needs and required mould will for described piston rod 2 and lid 1
Both single injection-moldeds, piston rod 2 is coaxial with lid 1, does not need carrying out subsequently both using injection moulding integrated molding
Connection, and be not in easily to occur both when split connects to depart from or connect eccentric problem.
It is provided with drive hole 11 and detection hole 12 in the upper end of lid as shown in Figure 1, drive hole 11 connects ventilation nozzle, and
Drive hole runs through lid 1, and when lid 1 is arranged on cylinder block, ventilation nozzle conveys gas by drive hole 11 into rigid body, from
And the piston piece in rigid body is done relative motion, realize the impetus of cylinder.Detection hole 12 is used for installing detection vacuum noz(zle),
Use for air-breathing detection when the head of cylinder is installed sucker or embraced tool.
As shown in Fig. 2 being provided with passage 21 inside piston rod 2, passage 21 one end therein is passed through inside lid 1,
The inside of lid 1 is provided with cross-drilled hole 13, by cross-drilled hole 13, with detection hole 12, passage 21 is formed path, so in cylinder head
Sucker or armful tool detection vacuum noz(zle) in back pressure when touching article are able to detect that whether article are embraced or held.
In order to reach the effect of sealing, be respectively equipped with lid 1 and piston rod 2 as shown in Figure 1 the first seal groove 14 and
Second seal groove 22, the first seal groove 14 is installed sealing ring when lid 1 is connected with cylinder block, better seal cylinder cylinder
Body.In the second seal groove 22, sealing ring is installed, one is to preferably be connected with piston piece, but the passage of closed interior
21, reach the effect of internal path and space outerpace sealing, more favorably detect the testing result accuracy of judgement of vacuum noz(zle).
The technology contents of the present invention and technical characteristic have revealed that as above, but those of ordinary skill in the art still may base
Make a variety of replacements without departing substantially from spirit of the present invention and modification, therefore, the scope of the present invention in teachings of the present invention and announcement
The content disclosed in embodiment should be not limited to, and the various replacements without departing substantially from the present invention and modification should be included, and be this patent Shen
Please claim be covered.
