Description

A kind of elastic packing positioning device
Technical field
The invention belongs to Machine Design manufacturing technology field, especially belong to the design and manufaction technical field of mechanism hand, particularly mechanism hand captures the elastic packing positioning device of fixing device.
Background technique
When mechanism hand captures fixed object, before needing mechanism hand, terminal tentacle has some specific functions.As in catalyst production process; usually can carry out the catalyst-coated processing of carrier; existing carrier generally adopts mechanism hand to capture; and need to seal carrier end face in coating procedure; and existing carrier sealing adopts the end face seal of rubber extruded formula; cause complex structure; and sealing is poor; the needs that carrier applies steady production fast can not be met; common Expansion sealing circle is adopted to carry out capturing and sealing; also because Expansion sealing circle is poorly sealed, non-homogeneous expansion is even, bulge, the phenomenons such as exhaust recoverability is poor cause effectively using for a long time.
Summary of the invention
The present invention discloses a kind of elastic packing positioning device according to the deficiencies in the prior art.The problem to be solved in the present invention is to provide one and is applied in catalyst carrier coating processing and uses, and has the elastic packing positioning device of better sealing, fixed performance.
The invention provides following technological scheme to realize:
Elastic packing positioning device, comprise the O-ring seal that elastic material is made and the annular brace seat installing seal ring, it is characterized in that: described seal ring cross section is outwardly open " U " shape structure, " U " shape both sides press seal of seal ring is also fixed by top board and press table by supporting base, and supporting base has vent.
The inwall on described seal ring " U " shape structure both sides all has the step convexed to form.
The groove that described supporting base two surface has the step convexed to form with seal ring " U " shape structure both sides inwall to mate.
The area of described groove cross section is not more than the area of the step cross section convexed to form.
Described supporting base and top board or press table are fixed by " U " shape both sides of bolt presses seal ring.
Above-mentioned elastic packing positioning device can be applicable to mechanism hand hand touch end, for catalyst carrier being fixed in catalyst cupport process.Seal ring in elastic packing positioning device adopts elastic material to make, and usually can adopt as the materials processing such as rubber, elastomeric plastics is made, seal ring is an annulus, and cross section is outwardly open " U " shape structure; The supporting base mated with seal ring is also a circle structure, when supporting base and seal ring combine, seal ring " U " shape structure both sides are conveniently enclosed within supporting base upper and lower two on the surface, and enough spaces are reserved in the bottom of " U " shape structure, the top board of two rings and press table are compressed respectively the both sides of " U " shape seal ring, fix by bolt presses, the space that " U " shape structural base is reserved forms the hollow ring of sealing, supporting base is provided with and is communicated with hollow ring and outside vent, usual vent can be communicated with external high pressure gas.
When carrying out catalyst carrier coating processing, carrier is placed in the annular seal circle of upper and lower two groups of elastic packing positioning devices, after being inflated by vent, carrier is fixed and is compressed carrier outer wall and forms carrier to external sealed by seal ring expansion, and after coating processing completes, in discharge seal ring, gas can take out carrier.
In order to ensure that the hollow ring volume that elastic packing positioning device headspace is formed is fixed, the inwall on seal ring " U " shape structure both sides is provided with the step convexed to form by the present invention, match and groove is set on supporting base two surface, the step convexed to form forms annulus at seal ring " U " shape inner structural wall, groove also forms the annulus of corresponding coupling on supporting base surface, and the area of usual groove cross section is not more than the area of step cross section.When supporting base and seal ring combine, step embeds in groove, and location is convenient, accurately, the elastic space size uniformity that hollow ring is formed, and it is better that the step formed at upper and lower pressing plate extruding lower convexity fills up groove sealability.
Helpfulness of the present invention: the present invention adopts " U " shape ring structure, fixing by the sealing of rigid support seat, the hollow ring formed is not yielding, carrier is fixing reliable, sealability is better, the further accurate stable of groove structure of protruding and coupling hollow ring volume is set, install and catalyst-coated process more convenient, sealability is better.

Embodiment
Below by embodiment, the present invention is conducted further description; the present embodiment is only for being further detailed the present invention; but can not be interpreted as limiting the scope of the invention, those skilled in the art can make some nonessential improvement according to the content of the invention described above and adjustment belongs to the scope of protection of the invention.
Composition graphs 1 to Fig. 5.
As shown in the figure, elastic packing positioning device, comprise the O-ring seal 1 that elastic material is made and the annular brace seat 4 installing seal ring 1, seal ring 1 cross section is outwardly open " U " shape structure, " U " shape both sides press seal of seal ring 1 is also fixed by top board 2 and press table 3 by supporting base 4, and supporting base 4 has vent 6.
The inwall on seal ring 1 " U " shape structure both sides can be provided with the step 1b convexed to form.The groove 4a that supporting base 4 liang of surfaces have the step 1b convexed to form with seal ring 1 " U " shape structure both sides inwall to mate.The area of groove 4a cross section is not more than the area of step 1b cross section.
Supporting base 4 is fixed by " U " shape both sides of bolt 5 press seal circle 1 with top board 2 or press table 3.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the seal ring 1 in elastic packing positioning device adopts elastic material to make, and usually can adopt as the materials processing such as rubber, elastomeric plastics is made, seal ring 1 is an annulus, and cross section is outwardly open " U " shape structure, the supporting base 4 mated with seal ring 1 is also a circle structure, seal ring 1 " U " shape structure both sides are enclosed within supporting base 4 when combining by supporting base 4 and seal ring 1, lower two on the surface, and enough spaces are reserved in the bottom of " U " shape structure, the top board 2 of two rings and press table 3 are distinguished two " U " shape limit of press seal circle 1, be fixed by bolt 5, the space that " U " shape structural base is reserved forms the hollow ring of sealing, supporting base 4 is provided with and is communicated with hollow ring and outside vent 6, usual vent 6 can be communicated with external high pressure gas.
As shown in Figure 5, when carrying out catalyst carrier 7 load process, carrier 7 is placed in the annular seal circle 1 of upper and lower two groups of elastic packing positioning devices, after being inflated by vent 6, seal ring 1 expands to be fixed by carrier 7 and compress carrier 7 outer wall and forms carrier to external sealed, and after load process completes, in discharge seal ring 1, gas can take out carrier 7.
In order to ensure that the hollow ring volume that elastic packing positioning device headspace is formed is fixed, also further the inwall on seal ring 1 " U " shape structure both sides can be provided with the step 1b convexed to form, match and groove 4a is set on supporting base 4 liang of surfaces, step 1b forms annulus at seal ring 1 " U " shape inner structural wall, groove 4a also forms the annulus of corresponding coupling on supporting base surface, and the area of usual groove 4a cross section is not more than the area of step 1b cross section.When supporting base 4 and seal ring 1 combine, the step 1b convexed to form embeds in groove 4a, and location is convenient, accurately, the elastic hollow annulus of formation is fixed, and forms sealability better under top board 2, press table 3 extruding.
