Abstract
The utility model provides a vacuum tooling air tightness test device, so as to solve the problems that the vacuum tooling air tightness test method in the prior art is time-consuming and labor-consuming, air leakage points are not easy to find in complicated pipeline and tooling and the like. The vacuum tooling air tightness test device comprises a negative pressure gauge, an air extraction pipe, a stop valve, a portable vacuum pump and a pipe stopper, wherein the portable vacuum pump, the stop valve and the negative pressure gauge are sequentially connected via the air extraction pipe and are connected with a tested pipeline or tooling; and pipe stoppers of various specifications are used for blocking through holes of various sizes of the pipeline or the tooling. The vacuum tooling air tightness test device has the beneficial effects that one section of pipeline or one piece of tooling in the complicated pipeline and the tooling can be selected to be the test object, and the air leakage points can be accurately and quickly found.
Description
Technical field
The utility model relates to a kind of vacuum frock airtight test technology, specially refers to a kind of vacuum frock air tightness checking device.
Background technology
In the digital control processing field of slim parts, often adopt vacuum frock to carry out clamping to slim parts.Therefore,, on its processing line, be provided with the different vacuum frock of shape size.In the use procedure of these vacuum frocks, due to reasons such as wearing and tearing and collisions, the impermeability of vacuum frock will change, and cause holding force lower, thereby cause clamping repeatedly, affect quality and the efficiency of clamping.Because vacuum frock is arranged on processing line, be difficult to it to investigate one by one, can only carry out globality inspection to the vacuum line of whole processing line and vacuum frock, not only waste time and energy, be also difficult for finding out gas leakage point from complicated pipeline and frock.Obviously, prior art vacuum frock airtight test method exists and wastes time and energy, and is difficult for finding out the problems such as gas leakage point from complicated pipeline and frock.
Summary of the invention
For solving wasting time and energy of prior art vacuum frock airtight test method existence, be difficult for finding out the problems such as gas leakage point from complicated pipeline and frock, the utility model proposes a kind of vacuum frock air tightness checking device.The utility model vacuum frock air tightness checking device comprises negative pressure table, exhaust tube, stop valve, portable vacuum pump and pipe stopper, wherein, portable vacuum pump, stop valve and vacuum table are linked in sequence by exhaust tube, and, be connected with detected pipeline or frock; The pipe stopper of all size is for the through hole of all size of the detected pipeline of shutoff or frock.
Further, the pipe stopper quantity of the utility model vacuum frock air tightness checking device is more than one.
Further, the negative pressure table measuring accuracy of the utility model vacuum frock air tightness checking device is more than 0.01Mpa.
The useful technique effect of the utility model vacuum frock air tightness checking device is in complicated pipeline and frock, to select one section of pipeline or a frock as detected object, finds out accurately, rapidly gas leakage point.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model vacuum frock air tightness checking device.
Below in conjunction with the drawings and specific embodiments, the utility model vacuum frock air tightness checking device is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model vacuum frock air tightness checking device, and in figure, l is vacuum table, and 2 is stop valve, and 3 is portable vacuum pump, and 4 is exhaust tube, and 5 is pipe stopper, and A is detected frock.As seen from the figure, the utility model vacuum frock air tightness checking device comprises negative pressure table 1, exhaust tube 4, stop valve 2, portable vacuum pump 3 and pipe stopper 5, wherein, portable vacuum pump 3, stop valve 2 and vacuum table 1 are linked in sequence by exhaust tube 4, and, be connected with detected pipeline or frock; The pipe stopper 5 of all size is for the through hole of all size of the detected pipeline of shutoff or frock.The utility model vacuum frock air tightness checking device adopts portable structure, can detect vacuum pipe or frock at processing line scene, and, can in complicated pipeline and frock, select one section of pipeline or a frock as detected object.In the time choosing a certain section of pipeline or a certain frock (as shown in the A of accompanying drawing 1) as detected object, first disconnect being connected of this frock and other pipelines, the through hole shutoff that adopts pipe stopper that this frock is connected with other pipelines, becomes an independently closed system.Because the hole size that detected pipeline or frock are connected with other pipelines is possible different, therefore, need to adopt the pipe stopper shutoff of all size to be detected the through hole of pipeline or frock all size.And pipe stopper quantity is more than one.After shutoff, the utility model vacuum frock air tightness checking device is connected to (referring to accompanying drawing 1) with detected pipeline or frock, opens portable vacuum pump, after vacuum table indicated number is stable, close stop valve, close portable vacuum pump.The indicated number of observing the pointer of negative pressure table, if indicated number remained unchanged in the long period, illustrates that this frock impermeability is good; If indicated number generation significant change, illustrates that this frock has the situation of gas leakage.Due in the time selecting detected object, be limited in a less scope, therefore, once the impermeability of this frock is poor, there is the situation of gas leakage, just can in this less scope, find out accurately, rapidly gas leakage point.For ensureing accuracy of detection and reliability, the negative pressure table measuring accuracy of the utility model vacuum frock air tightness checking device should be more than 0.01Mpa.
Obviously, the useful technique effect of the utility model vacuum frock air tightness checking device is in complicated pipeline and frock, to select one section of pipeline or a frock as detected object, finds out accurately, rapidly gas leakage point.
