The device clamps and fixes the engine. When it needs to be driven to flip, the motor 1 is controlled to drive the connecting frame to flip through the rotating shaft 1, thereby driving the clamped engine to flip. The rotating shaft 2 and the clamping plate 2 at the top of the rotating shaft 2 are driven to rotate by the controlling motor 3, thereby driving the clamped engine to rotate.

The engine is heavy, and the weight of other peripheral components makes the connection between the rotating shaft 1 and the connecting frame easily damaged, and the rotating support structure of the rotating shaft 1 is unevenly stressed and also easily damaged.

DETAILED DESCRIPTION

[0017] The utility model is described in detail according to the accompanying drawings of the specification.

[0018] like Figure 1 , Figure 2 As shown, the engine maintenance detection equipment includes a base plate 7, left and right support plates 12 spaced apart on the base plate 7, a horizontal rotation shaft 18 disposed between the two support plates 12, and a C-shaped support frame 2 connected to the horizontal rotation shaft 18.

[0019] Among them, a connecting arm 17 is fixed to the outer side of the lower inflection point of the C-shaped support frame 2, and a connecting sleeve 19 is provided at the end of the connecting arm 17, which is sleeved on the horizontal rotating shaft 18. In this embodiment, a sensing block 14 is provided at one end of the connecting sleeve 19, and the inner side wall of the support plate 12 is provided with upper and lower proximity switches 13 and 15 corresponding to the sensing block 14. The two proximity switches 13 and 15 are arranged around the horizontal rotating shaft 18 and the angle between the two is 90 degrees. The setting of the two proximity switches 13 and 15 facilitates the feedback of the rotation angle of the horizontal rotating shaft 18, which serves as the driving basis of the motor (omitted in the figure).

[0020] A horizontal turntable 5 is fixed to the inner bottom surface of the C-shaped support frame 2, an electric push rod 1 is fixed to the top surface of the C-shaped support frame 2, and the lower end of the electric push rod 1 is connected to a pressing plate 4 by a bearing 3, and the pressing plate 4 coincides with the center line of the horizontal turntable 5. In this embodiment, the inner ring surface of the bearing 3 is connected and fixed to the lower end of the electric push rod 1, and the lower end surface of the outer ring of the bearing 3 is connected and fixed to the pressing plate 4.

[0021] A hollow window 20 is provided on the side wall of the C-shaped support frame 2, and an upper and lower horizontal support arm 10 are provided on the outer side of the hollow window 20, and a roller assembly 11 is fixed by the two horizontal support arms 10, and the axis of the roller assembly 11 is parallel to the center line of the horizontal turntable 5. In this embodiment, the upper and lower ends of the wheel shaft 8 of the roller assembly 11 are respectively inserted into the U-shaped mounting openings of the upper and lower horizontal support arms 10, and the upper and lower ends of the wheel shaft 8 are provided with positioning plates 9 connected to the horizontal support arms 10, and the length direction of the U-shaped mounting opening is perpendicular to the center line of the horizontal turntable 5. The cooperation between the U-shaped mounting opening and the positioning plate 9 facilitates the adjustment of the distance between the roller assembly 11 and the engine.

[0022] The bottom plate 7 is provided with a front buffer seat 6 and a rear buffer seat 16 corresponding to the C-shaped support frame 2 at the front and rear positions of the support plate 12, respectively. In this embodiment, the top surface of the rear buffer seat 16 is used to contact the side wall of the C-shaped support frame 2 after flipping 90 degrees, so as to achieve stable support for the C-shaped support frame 2 in two working states. The front buffer seat 6 and the rear buffer seat 16 are respectively composed of a base 24, a buffer spring 23 provided on the base 24, and a buffer seat 21 provided on the top of the buffer spring 23, and the lower surface of the buffer seat 21 is provided with a guide column 22 inserted into the upper part of the buffer spring 23.

[0023] Working principle:

[0024] When in use, the engine is installed between the horizontal turntable 5 and the pressure plate 4 and tightened with the electric push rod 1, and the position of the roller assembly 11 is adjusted so that the outer peripheral surface of the roller of the roller assembly 11 contacts the outer periphery of the engine. This prevents the engine from moving in the horizontal direction during maintenance. Starting the horizontal turntable 5 can drive the engine and the outer ring of the bearing 3 and the pressure plate 4 to rotate to a suitable angle for easy maintenance. In this process, the induction block 14 approaches the proximity switch 13 at the upper position, and the bottom surface of the C-shaped support frame 2 contacts the top surface of the front buffer seat 6 to achieve stable support.

[0025] See also Figure 2When the engine angle needs to be adjusted, the motor is started to drive the horizontal shaft 18, the connecting sleeve 19, the connecting arm 17 and the C-shaped support frame 2 to turn counterclockwise 90 degrees around the center line of the horizontal shaft 18, so that the induction block 14 rotates 90 degrees synchronously. After the proximity switch 15 at the lower position sends a signal, the motor stops. At this time, the side wall of the C-shaped support frame 2 contacts the top surface of the rear buffer seat 16 to achieve stable support. In this working state, the roller of the roller assembly 11 improves the support stability of the engine without affecting its rotation.

[0026] The above is a detailed description of the embodiments of the utility model, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the invention of the utility model should still fall within the scope of this patent.
