Abstract

The invention discloses a clamp for examining the air tightness of an end cover part. The clamp comprises a base, a pressure head and a connecting rod, wherein a cavity for accommodating an end cover part to be examined is formed in the base, the end cover part to be examined penetrates through the connecting rod through a center hole to be arranged on the base, one end of the connecting rod is connected to the base, the other end of the connecting rod is connected with the pressure head, an air inlet nozzle communicated with the cavity is arranged on the side face of the base and is connected with an inflation device, and a sealing ring which is in sealed connection with the end cover part to be examined when pressed is arranged on the bottom of the pressure head. By the adoption of the clamp, assembly and disassembly can be achieved at one time without repetition, clamping is convenient, and examination gas is supplied from the side face so that air leakage of the part can be observed conveniently.

Description

A kind of for detecting the bubble-tight fixture of end cap part
Technical field
The present invention relates to a kind of fixture, particularly relating to a kind of for detecting the bubble-tight fixture of end cap part.
Background technology
At present, carry out air-leakage test at end cap part and make to be generally be positioned in clamp body by part, then clamp body is put into water, clamp body carries out air-leakage test from bottom inflow to part.Existing end cap part clamp for detecting air tightness is in concrete use procedure, and the problem that ubiquity may cause bubble normally to overflow fast because of the pressure of water, the accuracy that impact detects, causes the quality of part to there is certain hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of for detecting the bubble-tight fixture of end cap part, it has and facilitates parts fixation and detect feature accurately and reliably, to solve the problems referred to above that in prior art, end cap part air-leakage test exists.
For reaching this object, the present invention by the following technical solutions:
A kind of for detecting the bubble-tight fixture of end cap part, it comprises base, pressure head and connecting rod, wherein, described base offers the die cavity for accommodating detected end cap part, described detected end cap part be arranged on described base by centre bore through described connecting rod, one end of described connecting rod is connected on described base, the other end connects described pressure head, the side of described base is provided with the suction nozzle be connected with described die cavity, described suction nozzle connects aerating device, when being provided with compression bottom described pressure head and the sealing ring that is tightly connected of detected end cap part.
Especially, described pressure head connects described connecting rod by helicitic texture, and described pressure head offers internal thread, and the top of described connecting rod offers external screw thread.
Especially, the top of described pressure head offers preformed hole, can assemble boosting-rod carry out clamping to make pressure head.
Especially, when the end face of described base being provided with compression and the sealing ring that seals of detected end cap part.
Beneficial effect of the present invention is, only needing first time handling without the need to repeating, convenient mounting and clamping, and feeding detection gas from the side, putting into and being convenient to observe part gas leakage compared with prior art for detecting the bubble-tight fixture of end cap part.
Accompanying drawing explanation
Fig. 1 is the top view for detecting the bubble-tight fixture of end cap part that the specific embodiment of the invention 1 provides;
Fig. 2 be in Fig. 1 A-A to profile.
In figure:
1, base; 2, pressure head; 3, connecting rod; 4, detected end cap part; 5, die cavity; 6, suction nozzle; 7, preformed hole.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, one comprises base 1 for detecting the bubble-tight fixture of end cap part, pressure head 2 and connecting rod 3, described base 1 offers the die cavity 5 for accommodating detected end cap part 4, described detected end cap part 4 be arranged on the end face of described base 1 by centre bore through described connecting rod 3, one end of described connecting rod 3 is connected to the center of the die cavity 5 of described base 1, the other end is provided with external screw thread, described pressure head 2 offers internal thread, in described pressure head 2 passes through, external screw thread is connected on described connecting rod 3, the side of described base 1 is provided with the suction nozzle 6 be connected with described die cavity 5, described suction nozzle 6 connects aerating device, when being provided with compression bottom described pressure head 2 and the sealing ring that is tightly connected of detected end cap part 4, for ensureing its air-tightness, when also can be provided with compression on the end face of described base 1 and the sealing ring that seals of detected end cap part 4.
The top of described pressure head 2 offers preformed hole 7, can assemble boosting-rod carry out clamping to make pressure head 2.
During clamping, first pressure head 2 is taken off from connecting rod 3, then be arranged on connecting rod 3 by detected end cap part 4 by centre bore, step surface now bottom detected end cap part 4 is resisted against the end face of described base, then pressure head 2 is assemblied on connecting rod 3, rotary press head 2 makes pressure head 2 be pressed on described detected end cap part 4, now under the effect of sealing ring, form seal cavity between described detected end cap part 4 and described base 1, finally fixture is put into water together with detected end cap part 4, pass into detection gas from the side and carry out air-leakage test.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
