Summary of the invention
The utility model provides a kind of carriage airtight machine, and purpose is to solve the prior art problem, and providing a kind of can carry out the airtight machine that automatic impermeability detects to the motor product, and the motor product is examined entirely.
The utility model technical scheme that adopts of dealing with problems is:
The airtight machine of carriage is characterized in that: have support and controller, cantilever tip is provided with the lift cylinder of vertical setting, and the cylinder axis top is fixedly connected with and compresses support, compresses the support below and is provided with tank.The top that compresses support is vertically fixed with clamping cylinder, and the cylinder axis top of clamping cylinder is fixed with and compresses tool, and it is corresponding one by one with compressing the fixing workpiece base in support bottom to compress tool, also is communicated with the air pressure tracheae on the workpiece base.
On support, be provided with the air blowing tracheae.
Be provided with panel on support, the air blowing tracheae is fixed on the panel.
The beneficial effects of the utility model: this airtight machine makes things convenient for the impermeability of motor to detect, utilize tool with motor seal, put into water after pressurizeing to the motor inner inflatable by the air pressure tracheae then, see if there is bubble and produce, have to illustrate that then product is defective, no bubble produces represents that then product is qualified.Owing to adopt robotization to detect, can all motor products be detected, realized the robotization and the full inspection of motor air tightness test.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The airtight machine of carriage as shown in fig. 1 has support 1 and controller 2, and support 1 top is provided with the lift cylinder 3 of vertical setting, and the cylinder axis top is fixedly connected with and compresses support 4, compresses support 4 belows and is provided with tank 5.The top that compresses support 4 is vertically fixed with clamping cylinder 6, and the cylinder axis top of clamping cylinder 6 is fixed with and compresses tool 7, and it is corresponding one by one with compressing the fixing workpiece base 8 in support 4 bottoms to compress tool 7.Wherein the quantity of workpiece base 8 can be set according to actual conditions, as long as it is corresponding with one one to compress tool 7.For ease of motor to be measured convenient impermeability of observing when detecting, on workpiece base 8, also be communicated with air pressure tracheae 9, purpose is an inflation increase air pressure to motor 12 in, can produce bigger bubble when motor 12 is airtight in tank 5 when bad, makes things convenient for the staff to observe.Air pressure tracheae 9 is connected with the solenoid valve (not shown), by turning to of solenoid valve, both can make gas lead to motor 12 from air pressure tracheae 9, and gas is released by air pressure tracheae 9 from motor 12.For convenience will be by motor 12 product dryings of airtight test, on support 1, be provided with air blowing tracheae 10, two panels 11 (panel that only shows the back among the figure) before and after on support 1, being provided with in the present embodiment, air blowing tracheae 10 (a next side-blown gas tracheae only is shown among the figure) is separately fixed on two panels 11, in fact the tracheae 10 of blowing also can be arranged on other suitable places, concrete set-up mode is according to circumstances decided, the position is set also can according to circumstances be provided with of the tracheae 10 of blowing simultaneously.
Adopt the airtight machine of above-mentioned carriage as follows to the concrete operations step that motor carries out the impermeability detection:
Air pressure tracheae 9 and air blowing tracheae 10 pneumatic circuit with gas transmission is connected, open device power supply (DPS), motor 12 to be measured is put into workpiece base 8, press start button, clamping cylinder 6 descends, and by compressing tool 7 motor 12 is pressed in the workpiece base 8, makes motor 12 inside reach sealing state, pressurize to motor 12 inner inflatable by air pressure tracheae 9 then, can according to circumstances be provided with its pressing time.The back lift cylinder 3 that pressurizes descends, and drives to compress support 4 declines, and motor 12 immerses in the water-filled tank 5 with compressing support 4 declines, and its soak time can according to circumstances be provided with.Whether the staff observes motor 12 has bubble to produce, if having bubble to produce then prove that motor 12 sealings are defective, on the contrary then qualified.Test back lift cylinder 3 rises, turn to by the solenoid valve on the air pressure tracheae 9 then and release motor 12 air pressure inside, after air pressure has been let out, 10 pairs of motors 12 of air blowing tracheae are blown, and motor 12 surperficial water droplets are blown off, and its gassing time can according to circumstances be provided with, clamping cylinder 6 rises then, after clamping cylinder 6 risings finish, take off motor 12, whole testing process finishes.
Said process is robotization, and its control program sets in advance, has realized the robotization of motor air tightness test.Owing to detect to realize robotization, detect simple and conveniently, detect the full inspection of realization motor so can carry out impermeability to all motor products.
