Abstract
The utility model discloses a quick oil measuring device for an electromagnet. The quick oil measuring device comprises a lower box and an upper box, wherein the upper box is connected with the lower box by a hinge, and the upper box and the lower box can be combined closely; a one-way air valve is arranged on the upper box; a plurality of one-way air vents are formed on the side wall of the lower box; pore diameters of the one-way air vents are in interference fit with the outer diameter of an electric wire of the electromagnet to be measured; a rubber seal ring is arranged at the closed joint of the lower box and the upper box; and a pressure gauge is arranged on the lower box. By the quick oil measuring device for the electromagnet, the conditions of inaccurate detection of the electromagnet and long detection time are changed, and the original mode of detecting oil leakage by using a capillarity phenomenon is changed into a mode of discharging oil under pressure, so that the detection speed and detection accuracy are improved greatly, and the detection efficiency is improved substantially.
Description
Technical field
The utility model belongs to the industrial sewing machine field, relates to the detection of sewing machine component, is used to detect the whether device of leakage of oil of electromagnet in particular to a kind of.
Background technology
Along with the sewing machine industry more and more comprehensively develops; Common flat seam machine is gradually the demand that can not satisfy most of user, has automatic shearing so just produced, and the computer car of a series of functions such as backstitches; And the core component of computer car is exactly an electromagnet; But a lot of electromagnet now on the market are also undesirable, and especially oil leakage phenomenon is very serious, and a lot of products all is because electromagnet leakage of oil and cause dress material to be scrapped when making dress material.
General detection method is to put into the box that oil is housed to electromagnet in the prior art; Electric wire is placed on the box below; Through the time more than 20 days, a part of oil can reach wire terminations through capillarity, and this kind method is consuming time oversize and whether can not detect electromagnet accurately qualified.
The utility model content
For overcoming deficiency of the prior art, the purpose of the utility model is to provide a kind of electromagnet simple in structure, that can effectively improve detection efficiency and accuracy to survey oily device fast.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of electromagnet is surveyed oily device fast; It comprises a lower box and a upper box; Said upper box is connected with said lower box through hinge, and driving fit is equipped with a unidirectional valve valve together on the said upper box each other; The sidewall of said lower box is provided with several one-way vent, the electric wire external diameter interference fit of the aperture of described one-way vent and electromagnet to be measured.
Further, said lower box and driving fit place of said upper box are provided with rubber seal.
Further, also be provided with a tensimeter on the said lower box.
The measuring principle of the utility model is following:
Electromagnet to be measured is put in the said lower box, and the electric wire of electromagnet electromagnet to be measured passes from the exhausr port of said one-way vent, is put in outside the said lower box; Then, in said lower box, pour into the oil that a part is used to detect, require to overflow the electromagnet top; Then said rubber seal is embedded the opening part of said lower box upper end; Said upper box is installed on the rubber ring, puts down said hinge, make this device reach sealing; Use inflator to pour into air pressure from the said unidirectional valve valve on the upper box; Because the pressure in this device increases, the oil in the device will be extruded from the electric wire position of electromagnet, and wire terminations not have the electromagnet of oil be exactly certified products; Can from the said tensimeter of said lower box side, read internal pressure in the testing process, and can saidly judge with tensimeter whether this device reaches sealing.
Compared with prior art, the utlity model has following beneficial effect:
The electromagnet of the utility model is surveyed oily device fast and had been changed inaccurate for the electromagnet detection in the past; And the situation that the time is very long; The utility model makes the mode of originally having only with capillarity detection leakage of oil change into the fuel-displaced mode of pressure; Improve detection speed and accuracy greatly, significantly promoted detection efficiency.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of instructions, below with the preferred embodiment and the conjunction with figs. detailed description of the utility model.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 surveys the structural representation of oily device fast for the electromagnet of the utility model.
Label declaration among the figure: 1, lower box, 2, one-way vent, 3, tensimeter, 4, rubber seal, 5, upper box, 6, unidirectional valve valve, 7, hinge, 8, electromagnet to be measured.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to shown in Figure 1; A kind of electromagnet is surveyed oily device fast, and it comprises a lower box 1 and a upper box 5, and said upper box 5 is connected with said lower box 1 through hinge 7; And driving fit is together each other; One unidirectional valve valve 6 is installed on the said upper box 5, and the sidewall of said lower box 1 is provided with 10 one-way vent 2, the electric wire external diameter interference fit of the aperture of described one-way vent 2 and electromagnet to be measured 8.
Further, said lower box 1 is provided with rubber seal 4 with said upper box 5 driving fits place.
Further, also be provided with a tensimeter 3 on the said lower box 1.
The preferred case study on implementation that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
