Referring to fig. 1-5, the present invention discloses a horizontal vibration device for fast switching, which comprises a base 10, wherein an electromagnetic vibration table 20, a vibration table moving coil 30, a connector 40 and a horizontal table 50 are sequentially arranged on the base 10 along the horizontal direction. The connecting head 40 is fixed to the oscillating table moving coil 30 by a first locking assembly.

The connector 40 is provided with a first threaded hole 44 in an inclined manner, the horizontal platform 50 is provided with a first mounting hole in a penetrating manner, the first mounting hole and the axis of the first threaded hole 44 are on the same straight line, the horizontal platform 50 and the connector 40 are fixed through a first screw 51, and the first screw 51 is matched with the first mounting hole and the first threaded hole 44. By means of the first screw 51, a rigid connection of the horizontal platform 50 to the connection head 40 can be achieved. The angle between the central axis of the first threaded hole 44 and the horizontal platform 50 is 30-60 degrees, which is more convenient for locking.

As shown in fig. 1 and 4, the connecting head 40 is provided with a first limiting protrusion 43, and the first limiting protrusion 43 and the side surface of the connecting head 40 form an L-shaped limiting groove. The end of the horizontal platform 50 is disposed in the L-shaped limiting groove and is disposed in cooperation with the L-shaped limiting groove. When the horizontal table 50 is installed, first, the electromagnetic vibration table 20 is turned up by 90 °, the electromagnetic vibration table 20 and the vibration table moving coil 30 may be turned counterclockwise by 90 ° with reference to fig. 1, and the connector 40 is placed on the upper side of the vibration table moving coil 30 and fixed by the first locking assembly. Then, the electromagnetic vibration table 20, the electromagnetic moving coil and the connector 40 are turned back by 90 °, i.e. returning to fig. 1 and 4, the horizontal table 50 is clamped in the L-shaped groove due to the first limiting protrusion 43, and then the horizontal table 50 and the connector 40 are locked by the first screw 51. And because the first threaded hole 44 is obliquely arranged, the angle is convenient for locking the first screw 51, the operation is convenient, and the connection is stable. The first position-limiting protrusion 43 can ensure the fit between the horizontal platform 50 and the connecting head 40 to be accurate and not to be misplaced. In this manner, the rigid connection of the coil to the horizontal platform 50 is not possible until after completion. The electromagnetic vibration table 20 can be turned over electrically or manually. A driving source, such as a motor, may be provided on the frame, and the motor drives the electromagnetic vibration table 20 to turn. And can also be manually turned over.

A plurality of second mounting holes 31 are formed in the vibrating table moving coil 30, and a first through hole and a second through hole penetrate through the connector 40; the first locking assembly comprises a second screw 41 and a third screw 42. The second screw 41 is a positioning screw, the positioning screw includes a screw head 411, a positioning portion 412 and a threaded portion 413, the positioning portion 412 is in transition fit with the first through hole, and the threaded portion 413 is in threaded fit with the second mounting hole 31. The third screw 42 is screwed with the second through hole and the second mounting hole 31. When the vibration table is installed, a positioning screw is firstly used, so that the position of the connecting head 40 and the position of the vibration table moving coil 30 are fixed, and then the second screw 41 is used for enhancing the connecting strength. Thus, the precise fixation of the connecting head 40 and the vibrating table moving coil 30 can be realized. The function of the set screw is to achieve pre-fixing. As the vibrating table moving coil 30 is provided with a plurality of second mounting holes 31, the plurality of second mounting holes 31 are distributed in a circumferential manner, the second mounting holes 31 of the outer circumference ring are connected with the connecting head 40 by using positioning screws, and the second mounting holes 31 of the inner circumference ring are locked with the connecting head 40 by using third screws 42. In this way, the joint head 40 and the vibrating table moving coil 30 can be fixed by the cooperation of the second screw 41 and the third screw 42.

The second mounting hole 31, the first through hole and the second through hole are all horizontally disposed. For a set screw, the outer diameter of the threaded portion 413 is smaller than the outer diameter of the positioning portion 412. The outer diameter of the thread part 413 is smaller than that of the positioning part 412, so that the positioning of the positioning screw is more convenient.

The horizontal table 50 is provided with a first groove 52, the bottom of the first groove 52 is perpendicular to the first mounting hole, and the head of the first screw 51 abuts against the bottom of the first groove 52.

The connector 40 is further provided with a second limiting protrusion, the second limiting protrusion is located on the upper side of the first limiting protrusion 43, and the horizontal table 50 is located between the first limiting protrusion 43 and the second limiting protrusion.

In the field of vibration equipment technology, the vibration isolation air bag 70 is a conventional technology, and the vibration table moving coil 30 can be finely adjusted in the horizontal direction by inflating and deflating the vibration isolation air bag 70. Thus, the relative position between the connecting head 40 and the horizontal platform 50 can be adjusted more conveniently.

The machine base 10 is provided with a guide table 60, a horizontal guide rail 61 is arranged on the upper side of the guide table 60, and the horizontal table 50 is positioned on the horizontal guide rail 61. The horizontal guide rail 61 may facilitate the horizontal stage 50 to slide in the horizontal direction.

The utility model discloses when installing the horizontal stand 50, only need to overturn electromagnetic vibration platform 20 once to the top, later install connector 40, go back the upset again, so as long as realize once falling the platform operation, can accomplish the installation of horizontal stand. The traditional mode needs to be repeatedly reversed, namely, the electromagnetic vibration table is repeatedly rotated, and the steps are extremely complicated.
