Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention will be combined below to clearly and completely describe the technical solution in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
The present invention will be further described with reference to the following examples.
Example (b): anti sunken test equipment of automobile body, including pressure head and the installation section of thick bamboo 1 of being connected with hydraulic equipment, the bottom activity cartridge of installation section of thick bamboo 1 has internal thread sleeve 2, installs pressure sensor 3 on the interior roof of installation section of thick bamboo 1, and pressure removal pressure sensor 3 shifts up on the internal thread sleeve 2, installs ejector pin 5 on the interior roof of internal thread sleeve 2. After installing the pressure head on female screw sleeve 2, move down through hydraulic equipment drive installation section of thick bamboo 1 and can exert pressure to the door plant (place the door plant level on the workstation usually when examining, exert the pressure test from the top), it is also comparatively convenient to install the pressure head through the mode of screw thread installation.
The pressure head is a spherical rubber sleeve 8, the opening of the spherical rubber sleeve 8 is hermetically arranged at the bottom end of the connecting rod 6, the outer surface of the top end of the connecting rod 6 is provided with threads, the top end of the connecting rod 6 is provided with a piston hole communicated with the spherical rubber sleeve 8, the top end of the piston hole is provided with a press plug 7 in a matching mode, the piston hole and the spherical rubber sleeve 8 are filled with electrorheological fluid, and the outer wall of the spherical rubber sleeve 8 is connected with an electric connecting piece 11.
When the installation pressure head, be connected with internal thread sleeve 2 through connecting rod 6, when connecing internal thread sleeve 2 with connecting rod 6 soon in, ejector pin 5 can get into the piston hole gradually and will push down plug 7 gradually, and electrorheological fluids can get into spherical gum cover 8 gradually and prop big with spherical gum cover 8, consequently can change spherical gum cover 8's size through the degree of depth that adjustment connecting rod 6 got into in the internal thread sleeve 2. After the size of the spherical rubber sleeve 8 is properly adjusted, the electrorheological fluid inside the spherical rubber sleeve is electrified from the electric connection piece 11, so that the spherical rubber sleeve can be changed into a solid state, the whole spherical rubber sleeve 8 is changed into a hard state, pressure can be stably provided for a vehicle body, and the stable detection process is ensured.
Further, a spring 10 is connected between the plunger 7 and the bottom wall of the piston bore. The spring 10 provides pushing force for the press plug 7, so that the press plug can automatically reset when losing the pressure of the ejector rod 5, and then the spherical rubber sleeve 8 is driven to recover, and the adjustment is convenient.
Be equipped with spacing slider 9 on the outer wall of internal thread sleeve 2, set up on the lateral wall of installation section of thick bamboo 1 with the spout 4 of spacing slider 9 adaptation, the bottom of spout 4 is sealed.
In a natural state, the distance between the top end of the internally threaded sleeve 2 and the pressure sensor 3 is not more than 5 mm.
Cooperation through spacing slider 9 and spout 4 is with internal thread sleeve 2's rotation ability restriction, it can only move about from top to bottom to make it, operate more smoothly when meeting internal thread sleeve 2 bottom with connecting rod 6 soon, and internal thread sleeve 2 can not drop from 1 bottom of installation section of thick bamboo, its top is nearer apart from pressure sensor 3, when connecting rod 6 screw in is to internal thread sleeve 2, the top of connecting rod 6 can push up internal thread sleeve 2's bottom earlier, need provide certain thrust and just can make things convenient for the screw thread installation between connecting rod 6 and the internal thread sleeve 2, can promote internal thread sleeve 2 and shift up under the effect of thrust here, thereby make 2 tops of internal thread sleeve directly push up on pressure sensor 3, can carry out stable installation between internal thread sleeve 2 and the connecting rod 6 this moment, avoid causing the connecting rod 6 to be difficult to take place with the condition of internal thread sleeve 2 being connected.
It should be noted that the stem 5 is of cylindrical configuration. Because the connecting rod 6 always rotates in the process that the ejector rod 5 enters the piston hole, the ejector rod 5 is arranged to be cylindrical, the connecting rod 6 cannot be prevented from rotating, and the use is smoother.
