Embodiment
To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast accompanying drawing at present and specify embodiment of the present invention.
To shown in Figure 7, be a preferred embodiment of threaded hole sand holes pick-up unit of the present invention like Fig. 1, Fig. 4, the sand holes that are used for the threaded hole on the lamp casing that forging types such as die casting or sand casting process detect.This detection frock comprises slide cartridge 1, and referring to Fig. 3, Fig. 8 and Fig. 9, this slide cartridge 1 is cylindric; One of which end opening, the other end are fixed with rubber plug 2, in the present embodiment; Rubber plug 2 and 1 bonding connection of slide cartridge also can adopt other the connected mode that is suitable for, for example in the reality; Can on rubber plug 2, have and the adaptive annular groove in slide cartridge 1 end, slide cartridge 1 is inserted in this annular groove, to realize being connected of rubber plug 2 and slide cartridge 1; Slide cartridge 1 can be selected for use transparent or non-transparent material is processed, and the preferably clear material is processed, and is convenient to observe the situation of slide cartridge 1 inside.Rubber plug 2 is columniform solid rubber plug, and the diameter of rubber plug 2 is greater than the diameter of said threaded hole, can cover the threaded hole that is detected fully and can guarantee that the sealing thread hole is advisable.
In the present embodiment; The detection frock comprises that also the end by the opening of slide cartridge 1 is inserted into the injecting assembly 3 in the slide cartridge 1; Referring to Fig. 2; This injecting assembly 3 comprises injection housing 31, be positioned at the piston 32 of injection housing 31 and be arranged on the injection head 33 of the head of injection housing 31, and injecting assembly 3 can be selected injector for medical purpose commonly used or other syringes that are suitable for for use.
In the present embodiment, further, in order to prevent to use; Injecting assembly 3 rotates in slide cartridge 1, and influence detects effect, on the barrel of slide cartridge 1, has two gathering sills 11,12; The length of one of them gathering sill 12 is greater than the length of another gathering sill 11; The outer wall of injection housing 31 is provided with the locating piece 311 that cooperates with gathering sill 11,12, and situation shown in the drawings is the situation that locating piece 311 is arranged in gathering sill 11, when injection housing 31 slides in slide cartridge 1; Locating piece 311 moves along gathering sill 11, injection housing 31 is played the effect of guiding.When locating piece 311 was positioned at the bottom of gathering sill 11, the water side pierces through rubber stopper 2 of injection head 33 was like Fig. 6 and state shown in Figure 7; When locating piece (311) was positioned at the top of gathering sill 11, the water side of injection head 33 was positioned on the end face of bottom of rubber plug 2, like Fig. 4 and state shown in Figure 5.In the practical application, locating piece 311 also can be arranged in gathering sill 12.Locating piece 311 can adopt bonding mode to be arranged on the outer wall of injection housing 31.
It will be appreciated that; Gathering sill 11,12 can have only one; The purpose of the gathering sill that two length that adopt present embodiment differ is, when the length of threaded hole is more shallow, can locating piece 311 be placed the short gathering sill 11 of length; When the length of threaded hole is longer, can locating piece 311 be placed the long gathering sill 12 of length.Locating slot 11,12 also plays the effect of watch window except the effect of playing guiding, can observe the volume of the water in the injection housing 31 and the position of piston 32, and this is particularly suitable when slide cartridge 1 adopts non-transparent material.
More than introduced the concrete structure that threaded hole sand holes of the present invention detect the preferred embodiment of frock, introduced threaded hole sand holes detection method of the present invention below and how to implement.
Threaded hole sand holes detection method of the present invention adopts above-mentioned threaded hole sand holes detection frock to carry out, and during detection, comprises the steps: at least
S1 is with sucking water in the injection housing 31; The volume of water is according to the volume decision of threaded hole; The volume of the water in the injection housing 31 is preferably greater than the volume of threaded hole, needing to avoid the secondary water filling like this, and the water that is sucked can be common water; But whether the water that preferably has color is convenient to observe threaded hole and is seeped water on every side;
S2 pushes away before with injection housing, and the water side that makes injection head 33 is by exposing in the rubber plug 2;
S3 is pressed in the butt-end packing threaded hole of threaded hole with rubber plug 2, compresses rubber plug 2 with slide cartridge 1, makes rubber plug 2 be close to the end face of threaded hole;
S4 is injected into the water in the injection housing 31 in the threaded hole and keeps certain pressure; It specifically is the piston 32 that promotes injecting assembly 3; Water in the injection housing 31 is injected in the threaded hole, keeps the state of piston 32, make the water in the piston hole keep certain pressure to continue a period of time;
Whether S5 has water to ooze out around observing threaded hole, if there is not water to spill, explains that there are not sand holes in threaded hole, if leak, explains that then there are sand holes in threaded hole, need mend and fill out or other processing, stifled the above sand holes.
Screw sand holes of the present invention detect frock and detect sand holes through water filling in threaded hole; Need lamp outer casing not put into water; Avoid lamp casing is carried out assembly and disassembly, improved detection efficiency, reduced labour intensity; And detection frock of the present invention also has advantages such as simple in structure, easy to operate.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
