Abstract
Provided is a leakage testing apparatus of a main speed reducer housing. The leakage testing apparatus comprises a case body, a pressure gauge, a bottom plate, a movable plate, and an air injecting pipe. The leakage testing apparatus is characterized in that the bottom plate is fixed in the case body, that a push-and-pull cylinder is disposed under the bottom plate, that guiding pillars and the cylinder rod of the push-and-pull cylinder are installed on the bottom plate in a sliding manner. The movable plate is connected with the tops of the guiding pillars and the cylinder rod of the push-and-pull cylinder. A top clamping cylinder is assembled on the movable plate through a connection rack. A clamping head is disposed on the cylinder rod of the top clamping cylinder and is connected with the air injecting pipe. Side clamping cylinders are assembled on the movable plate. The cylinder rods of the two clamping cylinders are both equipped with clamping heads. The leakage testing apparatus has characteristics of accurate leaked point detection, low labor intensity, and substantially-increased work efficiency.
Description
Technical field
The utility model belongs to a kind of test unit of processing automobile parts, particularly a kind of final drive casing leakage testing device.
Background technology
When existing automobile component bevel housing carries out leak test, mainly adopt manual closure casing, then utilize hairbrush to dip in the method that suds are smeared, housing is smeared to discovery leak source, owing to can not 100% checking, put in place, time have undetected phenomenon to occur.
Summary of the invention
The purpose of this utility model is to provide a kind of final drive casing leakage testing device, checks that leak source is accurate, and labour intensity is low, and work efficiency is high.
The purpose of this utility model is achieved by the following technical solution: comprise casing, tensimeter, base plate, portable plate and air injection pipe, it is characterized in that: fixed base plate in casing, push-and-pull cylinder is set below base plate, on base plate, slide and install the cylinder rod of guidepost and push-and-pull cylinder, portable plate is connected to the cylinder rod upper end of guidepost and push-and-pull cylinder, clamping cylinder above assembling by link on portable plate, the cylinder rod of top clamping cylinder is provided with clamping head, on clamping head, connect air injection pipe, on portable plate, assemble both sides clamping cylinder, the cylinder rod of two clamping cylinders is equipped with and steps up head.
Advantage of the present utility model: check that leak source is accurate, labour intensity is low, significantly improves work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (the not front state of leak test of part of knocking off).
Fig. 2 is the utility model view while knocking off part leak test.
Embodiment
See Fig. 1, concrete structure is as follows: the interior fixed base plate 16 of casing 1, push-and-pull cylinder 2 is set below base plate 16, on base plate 16, slide and install the cylinder rod 15 of guidepost 3 and push-and-pull cylinder 2, portable plate 14 is connected to the upper end of guidepost 3 and cylinder rod 15, on portable plate 14, by stepping up cylinder 9 above link 7 assemblings, step up cylinder 9 Bonding pressure tables 8; The cylinder rod end that cylinder 9 is stepped up in top is provided with polyurethane clamping head 11, step up to connect air injection pipe 10 on 11, on portable plate 14, assemble the cylinder rod end that 13, two of both sides clamping cylinder 4 and clamping cylinders step up cylinder and be respectively equipped with polyurethane clamping head 5,12.
Principle of work: utilize pneumatic means closure casing, with pneumatic means, closure casing is immersed in tank, to injecting the gas of certain air pressure in housing, because housing seals, have bubble if any leak source and occur.
The course of work:
1. axle housing 6 is put on portable plate 14, by register pin, is located.
2 starting switch 17-1, cylinder 9 work, hold out against sealing axle housing 6.
3. starting switch 17-2, cylinder 4,13 work, hold out against sealing axle housing 6 two ends.
4. starting switch 17-3 cylinder 2 work, draw in portable plate 14 and axle housing 6 in leak test water.
5. starting switch 17-4, injects certain pressure gas.
6. whether observe housing has bubble to spill.
7. switch 17-4,17-3 are successively pulled to home position; Treat that portable plate 14 is raised on the water surface; Switch 17-2,17-1 are successively pulled to home position, and work completes.
