Description

Embrace tool head

Technical field

The utility model is related to a kind of part of cylinder, takes for embracing installed in cylinder head more particularly, to a kind of Embracing for article has head.

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.

Manipulator can imitate some holding functions of staff and arm, to by fixed routine crawl, carrying object or operation The automatic pilot of instrument.Manipulator is the earliest industrial robot for occurring, and is also the earliest modern machines people for occurring.It can Replace the heavy labor of people to realize the mechanization and the automation that produce, can operate under hostile environment to protect personal safety, Thus it is widely used in the departments such as machine-building, metallurgy, electronics, light industry and atomic energy.

Cylinder is installed in the head of cylinder for armful function of realizing cylinder and embraces a tool head, but the ventilation of existing armful of tool head Groove needs to set certain height due to needing to play cushioning effect, and due to embracing, to take the anti-applying power of article less during contact article When, the upper surface of air channel cannot block passage, not reach the purpose of vacuum, and do not have whether detect embrace get article Effect, if height it is less and less than buffering effect.

Utility model content

The purpose of this utility model is the defect for overcoming prior art, there is provided one kind embraces tool head, sets on air channel top There is elongated projection, the elongate recesses matched with elongated projection are provided with the bottom of air channel, to avoid groove height mistake of ventilating High detection has the article that head armful takes less than embracing, the too low effect for not having buffering.

For achieving the above object, the utility model proposes following technical scheme：Including tool head body is embraced, described armful has head sheet In vivo portion is provided with air channel, for buffering and playing suggesting effect；The top of the air channel is provided with elongated projection, the ventilation The bottom of groove is provided with the elongate recesses matched with the elongated projection, elongated under external force raised with the elongate recesses Engagement.

Preferably, described air channel one end is openend.

Preferably, mounting groove is additionally provided with described armful of tool head body, for installed in the head of cylinder.

Preferably, the upper end of the mounting groove is additionally provided with the passage coaxial with the mounting groove, the passage and institute State elongate recesses to communicate.

Further, diameter of the diameter of the passage less than mounting groove.

Preferably, described armful of tool head is made up of strong flexible polymer material.

Preferably, the strong flexible polymer material is elastomeric material.

The beneficial effects of the utility model are：By designing elongated raised and elongate recesses, ventilation groove height mistake is solved Height affects an armful tool head to can't detect armful article for taking, and the effect of buffering is not had when too low.

Description of the drawings

Fig. 1 is of the present utility model armful of tool head schematic perspective view；

Fig. 2 is the cross-sectional schematic of of the present utility model armful of tool head.

Reference：1st, tool head body is embraced, 11, air channel, 111, elongated projection, 112, elongate recesses, 12, mounting groove, 13rd, passage.

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 shown in Fig. 1, Fig. 2, the tool head of embracing disclosed in the utility model is arranged on the cylinder head of cylinder and in cylinder Head installs an intermediate plate, and intermediate plate is fixed on the cylinder body of cylinder, have certain gap between tool head with embracing, when object is reached Cylinder promotes embrace tool head so that article is embraced and taken forward during gap.Embracing tool head includes embracing tool head body 1, is internally provided with air channel 11, the top of air channel 11 is provided with elongated convex 111, and the bottom of air channel 11 is provided with and matches with described elongated convex 111 Elongate recesses 112, elongated raised 111 have certain gap in the presence of external force is not received with elongate recesses 112, in outer masterpiece Elongated raised 111 move down and are engaged with elongate recesses 112 with.Mounting groove 12 is additionally provided with the lower end for embracing tool head body 1, is led to Cross mounting groove 12 and will embrace tool head installed in the front end of cylinder block, passage 13 is provided between mounting groove 12 and elongate recesses 112, And form path.When an armful tool head embraces object, object has a head reaction force to embracing so that the upper table of air channel 11 is towards an armful tool The internal pressure of head, elongated raised 111 move down engaged with elongate recesses 112 under force, now, elongated raised 111 Upper surface closure passage 13, and show to have embraced to vacuum generator input signal and get article.It is long in normal state There is a less gap (not shown) between shape raised 111 and elongate recesses 112, this less gap can play one Fixed cushioning effect, while having drawn in the distance of buffering, needs less power to be capable of achieving elongated when embracing tool head and embracing article The closure of raised 111 pairs of passages 13, and make cylinder interior form vacuum state so that being connected to the test side of tail cylinder Vacuum generator receive signal and point out to have embraced and take article.

As shown in Figure 2 the diameter of passage 13 is ventilated less than the diameter of mounting groove 12 so as to reach elongated raised 111 closure The purpose in hole.

Of the present utility model armful of tool head is preferably adopted, and there is strong flexible polymer material to make, such as rubber material.Energy Preferably the article for taking is embraced in protection enough to have certain elasticity.

The utility model avoids air channel excessive height and can't detect to embrace has the article that head armful takes, too low not have buffering Effect.

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.
