Abstract

The utility model discloses a lid behind cylinder disjunctor, lid and edge the outside piston rod that extends in lid one side, the lid with as an organic whole the moulding plastics of piston rod forms for the lid reaches coaxial effect with the piston rod, and it is rapid to reduce the processing work step, and can avoid other connected modes to make lid and piston rod decentraction or is connected the waste that the lower and cost of cylinder work efficiency was brought to factor such as unstability, and is equipped with the inspection hole and drives the hole on the lid, can realize that a drive function can detect the sucking disc or the locking device that are connected with the cylinder again and whether absorb or embrace the object.

Description

Cylinder disjunctor bonnet

Technical field

The utility model is related to a kind of cylinder, more particularly, to the cylinder back cover in a kind of cylinder.

Background technology

Commonly use cylinder in industry to carry out the carrying of workpiece, position and drive other devices.Existing cylinder can be installed To in manipulator jig, the crawl of product is completed with manipulator jig cooperation, existing cylinder mostly is single-action type cylinder, general Sucker can be installed additional and tool head is embraced, and transfer block then need to be separately installed additional on cylinder when sucker is installed.Under the promotion of external gas source, inhale Disk and an armful tool head can only do elastic motion, so as to the absorption to product and gripping can only be realized under the drive of manipulator, The function of realization is relatively simple；And the detection Multi-purpose mechanical switch detection of existing cylinder.And connection lid and the work of cylinder back cover The connection great majority of stopper rod are using connected modes such as gluing or screw threads.

The applicant applied for an entitled cylinder, Application No. CN201410289222.X on June 25th, 2014 Utility model patent disclose cylinder back cover, including lid and the piston rod that is fixed on the lid are opened on the lid Drive hole and detection hole are provided with, the drive hole runs through the lid, and the piston rod is interior to be offered and institute along its axial direction The sense channel that detection hole communicates is stated, the piston rod is fixed on the lid by gluing mode.This cylinder back cover Lid is linked together with piston rod by the mode for then passing through gluing, plus man-hour is more time-consuming, if the improper appearance of injecting glue Easy to stick eccentric or distortion, such cylinder thrust when left linear thrust is acted on concentrates certain position and does not reach cylinder and normally run Effect.

Utility model content

The purpose of this utility model is the defect for overcoming prior art, there is provided a kind of cylinder disjunctor bonnet, by piston Bar is made to improve the operating efficiency of cylinder with the integral type injection of lid.

For achieving the above object, the utility model proposes following technical scheme：It is including lid and lateral along the lid one The piston rod of outer extension, the cross section of the lid and piston rod is concentric circles, and the lid is integrated with the piston rod It is molded.

Preferably, the upper end of the lid is provided with a drive hole and detection hole.

Preferably, the drive hole is through the whole lid.

Preferably, the piston rod inner is provided with the passage coaxial with the piston rod, and described passage one end is to open Mouthful, the other end is passed through lid portion inside.

Preferably, the detection hole is attached by a cross-drilled hole vertical with the passage with the passage and is passed through It is logical.

Preferably, the first seal groove is additionally provided with the lid, for placing sealing ring.

Preferably, the piston rod with the lid opposite side is provided with the second seal groove, for placing sealing ring.

The beneficial effects of the utility model are：Lid and piston rod integrated injection forming, it is possible to reduce tooling step is rapid, And other connected modes can be avoided so that lid and piston rod decentraction or being connected the factor such as unstable and bringing cylinder operation to imitate Rate is relatively low and waste of cost.

Specific embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out clear, complete Description.

With reference to Fig. 1, Fig. 2, the cylinder disjunctor bonnet disclosed in the utility model is connected to the end of the cylinder body of cylinder, is used for Closed cylinder and to cylinder cylinder interior Input gas so as to the motion of drive cylinder internal piston part.Cylinder disjunctor bonnet bag Lid 1 and piston rod 2 are included, the piston rod 2 by way of injection, arranges the parameter and required mould for needing with lid 1 By both single injection-moldeds, piston rod 2 is coaxial with lid 1 to tool, need not carried out both using injection moulding integrated molding Follow-up connection, and be not in easily occur both when split connects to depart from or connect eccentric problem.

As shown in Figure 1 drive hole 11 and detection hole 12 are provided with the upper end of lid, ventilation nozzle is connected on drive hole 11, 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 to install detection vacuum noz(zle), Use for air-breathing detection when the head of cylinder installs sucker or embraces tool.

As shown in Fig. 2 being provided with passage 21 inside piston rod 2, the one end therein of passage 21 is passed through inside lid 1, The inside of lid 1 is provided with cross-drilled hole 13, passage 21 is formed into path with detection hole 12 by cross-drilled hole 13, so in cylinder head Sucker or armful tool detect that vacuum noz(zle) is able to detect that whether article is embraced or held when article is touched in back pressure.

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, on the first seal groove 14 install sealing ring when lid 1 is connected with cylinder block, better seal cylinder cylinder Body.Sealing ring is installed in the second seal groove 22, one is but the passage of closed interior in order to preferably be connected with piston piece 21, the effect of internal path and space outerpace sealing is reached, more favorably detect the testing result accuracy of judgement of vacuum noz(zle).

Technology contents of the present utility model and technical characteristic have revealed that as above, but those of ordinary skill in the art still may be used A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement, therefore, this Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model And modification, and covered by present patent application claim.
