Abstract
The invention relates to the field of water pump production detection, and particularly relates to a water pump leakage detection apparatus. The water pump leakage detection apparatus comprises a box body, a down-pressing air cylinder which is arranged at the upper portion of the box body and is connected with the box body through a support, a three-point self-balancing fixture which is arranged under the down-pressing air cylinder, a test platform which is arranged under the three-point self-balancing fixture, and a pressure ejection device which is arranged under the test platform and is used for connecting a water pump and is provided with a pressure detection device. The three-point self-balancing fixture comprises a down-pressing seat which is connected with the down-pressing air cylinder, a clamping seat which is connected with the down-pressing seat through elastic connecting devices at the four corners, and three parallel clamping columns which are arranged at the lower end of the clamping seat; a spherical steering mechanism is arranged between the down-pressing seat and the clamping seat; and the three parallel clamping columns are not distributed on the same straight line. With the water pump leakage detection apparatus, accurate water pump leakage situations can be obtained without using a water test method, and therefore, the water pump can be prevented from being polluted by test-used water, and accurate leakage parameters can be obtained; and the clamping columns clamp workpieces one point by one point in the clamping process, and therefore, the surface of the water pump can be prevented from being damaged, and an excellent clamping effect can be maintained.
Description
Technical field
The present invention relates to water pump production testing field, particularly relate to a kind of water pump leakage detecting equipment.
Background technology
Water pump will through test before dispatching from the factory, water pump leakage detecting is the important content of test before water pump dispatches from the factory, current water pump leakage detecting method is water examination method, namely in water pump, water is put into after note pressure, whether observe has bubble to produce, this kind of method makes the test water capacity easily pollute water pump, and can not obtain leakage parameters accurately.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of and prevent test water pollutions water pump and can obtain the water pump leakage detecting equipment of accurate leakage parameters.
A kind of water pump leakage detecting equipment, comprise casing, be located at the lower air cylinder be connected by support with casing above casing, be located at 3 self-equilibrating fixtures under lower air cylinder, be located at the test platform under 3 self-equilibrating fixtures, be located under test platform for be connected with water pump and with the press-contacting device of pressure-detecting device, described 3 self-equilibrating fixtures comprise the down pressing seat be connected with lower air cylinder, the clamping seats connected by the elastic connecting device of corner with down pressing seat and be located at the parallel clamping column of three of clamping seats lower end, spherical steering mechanism is provided with between described down pressing seat and clamping seats, described three clamping columns arrangement is not point-blank.
Described three clamping columns arrangement is parallel two clamping columns of left end, right-hand member clamping column.
The invention has the beneficial effects as follows:
Due to when water pump being clamped by 3 self-equilibrating fixtures, press-contacting device is water pump note pressure, pressure-detecting device detects pressure drop situation in water pump, thus obtain accurate leakage parameters, method is tried without the need to using water, just water pump leakage situation accurately can be obtained, prevent test water pollutions water pump, described 3 self-equilibrating fixtures comprise the down pressing seat be connected with lower air cylinder, the clamping seats connected by the elastic connecting device of corner with down pressing seat and be located at the parallel clamping column of three of clamping seats lower end, spherical steering mechanism is provided with between described down pressing seat and clamping seats, described three clamping columns arrangement is not point-blank, the clamping work pieces of clamping column pointwise in clamping process, prevent water pump surface breakdown and keep good clamping effect.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is left TV structure schematic diagram of the present invention.
In figure: 1. down pressing seat, 2. elastic connecting device, 3. clamping seats, 4. spherical steering mechanism, 5. clamping column, 6. casing, 7. descend air cylinder, 8. press-contacting device, 9. pressure-detecting device.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing and most preferred embodiment, the present invention is described in further detail.
As shown in the figure, the present invention includes casing 6, be located at the lower air cylinder 7 be connected by support with casing above casing, be located at 3 self-equilibrating fixtures under lower air cylinder, be located at the test platform under 3 self-equilibrating fixtures, be located under test platform for be connected with water pump and with the press-contacting device 8 of pressure-detecting device 9, described 3 self-equilibrating fixtures comprise the down pressing seat 1 be connected with lower air cylinder, the clamping seats 3 connected by the elastic connecting device 2 of corner with down pressing seat and be located at the parallel clamping column 5 of three of clamping seats lower end, spherical steering mechanism 4 is provided with between described down pressing seat and clamping seats, described three clamping columns arrangement is not point-blank.
Due to when water pump being clamped by 3 self-equilibrating fixtures, press-contacting device is water pump note pressure, pressure-detecting device detects pressure drop situation in water pump, thus obtain accurate leakage parameters, method is tried without the need to using water, just water pump leakage situation accurately can be obtained, prevent test water pollutions water pump, described 3 self-equilibrating fixtures comprise the down pressing seat be connected with lower air cylinder, the clamping seats connected by the elastic connecting device of corner with down pressing seat and be located at the parallel clamping column of three of clamping seats lower end, spherical steering mechanism is provided with between described down pressing seat and clamping seats, described three clamping columns arrangement is not point-blank, the clamping work pieces of clamping column pointwise in clamping process, prevent water pump surface breakdown and keep good clamping effect.
During work, pressue device drives down pressing seat to decline, clamping seats drives three clamping columns and water pump surface contact, wherein a clamping column contacts with the peak of water pump, down pressing seat continues to decline, clamping seats is under the effect of elastic connecting device and spherical steering mechanism, tilt rotation, second clamping column contacts with water pump, and down pressing seat continues to decline, and clamping seats is under the effect of elastic connecting device and spherical steering mechanism, tilt rotation, 3rd clamping column contacts with water pump, completes the self-equilibrating clamping of 3, tests.
Described three clamping columns arrangement is parallel two clamping columns of left end, right-hand member clamping column.Good clamping effect can be ensured.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
