A pressure plate matching the top of the engine bracket to be tested is detachably mounted on the rectangular ring plate, and a position-adjustable fixing component is arranged on the base for fixing the engine bracket. The utility model engine bracket is easy to fix and has a good test effect.

[0004] However, during the use of the utility model, after the pressure plate presses the engine bracket, the vibrator drives the engine bracket to vibrate, and at the same time, the entire device will be vibrated. If the vibration frequency is too large, it may cause the entire device to shift, causing a certain impact on the device and failing to meet production needs. Therefore, an automobile engine bracket vibration detection tooling is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a vibration detection tool for an automobile engine bracket, which has the advantage of avoiding vibration of the entire device, and solves the problem that when the pressure plate presses the engine bracket, the vibrator drives the engine bracket to vibrate, and at the same time drives the entire device to vibrate. If the vibration frequency is too large, it may cause the entire device to shift, causing a certain impact on the device and failing to meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vibration detection tool for an automobile engine bracket, comprising a workbench and a placement table arranged on the top of the workbench and extending to the inside thereof, a vibration detection mechanism for vibrating the placement table is arranged inside the workbench, and a flexible clamping structure for clamping the engine bracket is arranged inside the placement table;

[0007] The vibration detection mechanism includes a double-axis motor fixedly connected to the inside of the workbench, a connecting shaft is fixedly connected to the output shaft of the double-axis motor, an eccentric wheel is fixedly connected to one end of the connecting shaft away from the double-axis motor, the top of the eccentric wheel abuts against the bottom of the placement table, and a first spring is fixedly connected to the opposite side of the placement table and the workbench;

[0008] The flexible clamping structure includes a bidirectional threaded rod rotatably connected to the inside of the placement table, the external thread of the bidirectional threaded rod is connected to a threaded sleeve, the top of the threaded sleeve is provided with a fixing member extending to the top of the placement table, and one side of the fixing member is slidably connected to an elastic clamping rod extending into the inside thereof.

[0009] Furthermore, there are two eccentric wheels, which are symmetrically distributed on the front and back sides of the dual-axis motor.

[0010] Furthermore, a connecting block is fixedly connected between the threaded sleeve and the fixing piece, a movable groove adapted to the connecting block is opened on the upper surface of the placing table, and a handle for rotating the bidirectional threaded rod is rotatably connected to one side of the placing table.

[0011] Furthermore, a reset spring is fixedly connected between the fixing member and the elastic clamping rod, the number of the fixing members is two, and the two fixing members are symmetrically distributed on the top of the placement table.

[0012] Furthermore, a mounting tube is fixedly connected inside the workbench, a connecting rod extending into the mounting tube is fixedly connected to the bottom of the placement table, and a second spring is fixedly connected between the connecting rod and the mounting tube.

[0013] Furthermore, a threaded rod is rotatably connected to the top of the placement table, an external thread of the threaded rod is connected to a top plate, and a pressure block is fixedly connected to a side of the top plate close to the placement table.

[0014] Furthermore, a rotating handle is fixedly connected to the top of the threaded rod, and a positioning guide rod is fixedly connected to the top of the placement table. The positioning guide rod passes through the top plate and is slidably connected to the top plate.

[0015] Compared with the prior art, the utility model provides a vehicle engine bracket vibration detection tooling, which has the following beneficial effects:

[0016] 1. The automobile engine bracket vibration detection tooling drives the connecting shaft and the eccentric wheel to rotate by setting a double-axis motor, and then drives the placement table to move up and down by the eccentric wheel. At this time, since a first spring is arranged between the placement table and the workbench, the placement table can produce elastic activities, and then due to the action of the eccentric wheel, the placement table can vibrate elastically, thereby achieving a vibration effect. Since only the placement table is vibrated, the workbench can be prevented from vibrating along with the placement table, and the workbench can be prevented from shifting, thereby improving the protection of the device.

[0017] 2. The automobile engine bracket vibration detection tool drives the bidirectional threaded rod to rotate by turning the handle, so that the bidirectional threaded rod can drive the threaded sleeve and the fixing part to move. When the engine bracket is placed between the two fixing parts, the fixing part drives the elastic clamping rod to move. At this time, the elastic clamping rod will be squeezed due to the reaction force of the engine bracket, so it can be suitable for engine brackets of different shapes without the need to replace different clamping parts. The practicability of the device is improved, and the problem that when the pressure plate presses the engine bracket, the vibrator drives the engine bracket to vibrate, and at the same time drives the entire device to vibrate. If the vibration frequency is too large, it may cause the entire device to shift, which has a certain impact on the device and cannot meet the production needs. BRIEF DESCRIPTION OF THE DRAWINGS
