Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Fig. 1, Fig. 4 to Fig. 7, be a preferred embodiment of threaded hole sand holes pick-up unit of the present invention, the sand holes of the threaded hole on the lamp casing that the forging types such as die casting or sand casting are made detect.This detection frock comprises slide cartridge 1, referring to Fig. 3, Fig. 8 and Fig. 9, this slide cartridge 1 is cylindric, its one end open, the other end is fixed with rubber plug 2, in the present embodiment, rubber plug 2 connection bonding with slide cartridge 1, also can adopt other the connected mode be suitable for, such as in reality, the annular groove with slide cartridge 1 end adapter can be had on rubber plug 2, be inserted into by slide cartridge 1 in this annular groove, to realize the connection of rubber plug 2 and slide cartridge 1, slide cartridge 1 can select transparent or non-transparent material to make, preferably clear material is made, and is convenient to the situation observing 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 described threaded hole, can cover detected threaded hole completely and can ensure to be advisable in sealing thread hole.
In the present embodiment, detect frock and also comprise the injecting assembly 3 be inserted into by one end of the opening of slide cartridge 1 in 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 head of injection housing 31, and injecting assembly 3 can select conventional injector for medical purpose or other syringes be suitable for.
In the present embodiment, further, during in order to prevent from using, injecting assembly 3 rotates in slide cartridge 1, affect Detection results, 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 coordinated with gathering sill 11,12, 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 to the effect of guiding.When locating piece 311 is positioned at the bottom of gathering sill 11, the water side pierces through rubber stopper 2 of injection head 33, state as shown in Figure 6 and Figure 7; When locating piece (311) is positioned at the top of gathering sill 11, the water side of injection head 33 is positioned on the end face of the bottom of rubber plug 2, state as shown in Figure 4 and Figure 5.In 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 only have one, the object of the gathering sill that the present embodiment adopts two length to differ is, when the length of threaded hole is more shallow, locating piece 311 can be placed in the shorter gathering sill of length 11, when the length of threaded hole is longer, locating piece 311 can be placed in the longer gathering sill of length 12.Locating slot 11,12, except the effect playing guiding, also plays the effect of watch window, and can observe the volume of the water in injection housing 31 and the position of piston 32, this is particularly applicable when slide cartridge 1 adopts non-transparent material.
Be described above the concrete structure that threaded hole sand holes of the present invention detect the preferred embodiment of frock, introduce 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, at least comprises the steps:
S1 sucks water by injection housing 31, the volume of water determines according to the volume of threaded hole, the volume of the water in injection housing 31 is preferably greater than the volume of threaded hole, avoid like this needing secondary water filling, the water sucked can be common water, but whether the coloured water of preferably with, be convenient to observe around threaded hole and seep water;
S2 pushes away before injection housing, and the water side of injection head 33 is exposed by rubber plug 2;
Rubber plug 2 is pressed in the butt-end packing threaded hole of threaded hole by S3, compresses rubber plug 2 with slide cartridge 1, makes rubber plug 2 be close to the end face of threaded hole;
Water in injection housing 31 to be injected in threaded hole and to keep certain pressure by S4, specifically promote the piston 32 of injecting assembly 3, water in injection housing 31 is injected in threaded hole, keeps the state of pushing piston 32, make pressure durations a period of time that the water in piston hole keeps certain;
Whether S5 observes around threaded hole has water to ooze out, if do not have water to spill, illustrates that threaded hole does not exist sand holes, if leaked, then illustrates that threaded hole exists sand holes, needs to carry out benefit and fills out or other process, block described sand holes.
Screw sand holes of the present invention detect frock by detecting sand holes to water filling in threaded hole, lamp outer casing is not needed to put into water, avoid carrying out assembly and disassembly to lamp casing, improve detection efficiency, reduce labour intensity, and detection frock of the present invention also has the advantages such as structure is simple, easy to operate.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
