Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Embodiment 1, to almost all the cabinets that do the vibration test at present, all need a special frock, the problem that the frock is scrapped after the experiment. The embodiment discloses become vibration test frock for oar switch board, including four swing joint boards, still be equipped with an adjusting plate on every swing joint board, all set up the screw hole on swing joint board and adjusting plate, become the four corners of oar switch board and pass through bolt and an adjusting plate fixed connection respectively, the adjusting plate then passes through bolt and rather than the swing joint board fixed connection that corresponds, the swing joint board passes through the bolt fastening on the vibration test platform.
As shown in fig. 1, the movable connecting plate 1 includes two long waist-shaped holes 11 side by side and a group of threaded hole array 12, the movable connecting plate is fixedly connected with the vibration test bed through a plurality of bolts penetrating through the long waist-shaped holes, and the adjusting plate and the movable connecting plate are fixedly mounted together through a plurality of bolts penetrating through partial threaded holes on the corresponding adjusting plate and the threaded hole array.
As shown in fig. 2, the adjusting plate 2 is divided into an upper layer and a lower layer, two long waist-shaped holes 21 are arranged on the adjusting plate on the lower layer side by side, the adjusting plate is fixedly connected with the movable connecting plate through a plurality of bolts penetrating through the long waist-shaped holes, a threaded hole 22 is arranged on the adjusting plate on the upper layer, and the adjusting plate is fixedly connected with the pitch control cabinet through the bolts penetrating through the threaded hole.
As shown in fig. 3, in actual use, according to the shape and size of a cabinet body to be subjected to a vibration experiment, the movable connecting plates 1 are respectively and fixedly mounted at appropriate positions on the vibration test bed 3 through bolts, the two movable connecting plates are horizontally arranged, the two movable connecting plates are vertically arranged, the horizontally arranged movable connecting plates are opposite to each other, the directions of the long kidney-shaped holes on the movable connecting plates are consistent, the vertically arranged movable connecting plates are parallel to each other and are perpendicular to the horizontally arranged movable connecting plates, and the directions of the long kidney-shaped holes on the movable connecting plates are consistent; and then the four adjusting plates 2 are respectively installed on four corners of the cabinet body 4 through bolts, and then the four adjusting plates 2 on the cabinet body are respectively installed on the movable connecting plates 1 corresponding to the four adjusting plates through bolts, wherein the installation directions of the four adjusting plates are consistent, and the directions of the long waist-shaped holes are also consistent. Due to the fact that the threaded hole array is formed in the movable connecting plate, under the condition that the position of the movable connecting plate is not changed, the adjusting plate is only required to be installed in a proper threaded hole in the threaded hole array through a bolt when the size of the cabinet body is changed, and the cabinet is very convenient to use. When the longitudinal distance of the cabinet body mounting hole is changed, the adjusting plate is slid to a proper position according to the distance; when the transverse distance of the cabinet body mounting hole is changed, the movable connecting plate is slid to a proper position according to the size of the distance; when the distance between the two mounting holes close to each other is changed, the adjusting plate is slid to a proper position.
