[0002] The automobile engine provides power for the automobile and is one of the important parts in the automobile. In order to ensure the stability and firmness of the automobile engine installation, the engine usually adopts a rear bracket to assist in installation and fixation. The prior art CN213565411U discloses a right rear bracket of an automobile engine, which includes a base and a front bracket connected to the base, and the base is connected to the automobile frame through the connecting hole of the base, and the front bracket is connected to the engine through the connecting hole of the front bracket.

[0003] The front bracket connecting hole of the engine rear bracket needs to be countersunk during processing. Since the engine rear bracket is small in size and the base and front bracket have irregular structures, it is difficult to clamp and fix the casting during countersunking. At the same time, since the engine rear bracket is cast, the surface of the casting is uneven, and there are differences in the fixed reference surface. The coaxiality of the countersunk hole and the connecting hole after fixation is also difficult to ensure, which will reduce the quality of the engine rear bracket. Utility Model Content

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0017] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a countersinking device for rear support of automobile engine of this embodiment comprises a base 1, a support 2, a support mechanism 3 and a tightening mechanism 4 are arranged above the base 1, the support mechanism 3 and the tightening mechanism 4 are respectively located at two sides of the support 2, at least two positioning columns 5 are arranged above the support 2, the support mechanism 3 comprises a support plate 31 and a driving mechanism 32 for driving the support plate 31 to move up and down, the tightening part of the tightening mechanism 4 is located at the side of the support 2, and the axis of the tightening part of the tightening mechanism 4 is horizontal and perpendicular to the positioning column 5. The driving mechanism 32 is a telescopic spring, which is sleeved on the outside of the guide rod 33, one end of the telescopic spring is connected to the base 1, and the other end is connected to the support plate 31, and the support plate 31 is slidably connected to the guide rod 33.

[0020] The working principle of the utility model is as follows: when working, the connection hole of the front bracket part of the engine rear bracket is sleeved on the positioning column 5, and the base part of the engine rear bracket is placed above the support plate 31 of the support mechanism 3, and the support mechanism 3 provides support to the base end of the engine rear bracket to reduce the weight of the base of the engine rear bracket; the tightening mechanism 4 acts on the top of the front bracket of the engine rear bracket, applies a horizontal force perpendicular to the positioning column 5 to the engine rear bracket, realizes the fixation of the engine rear bracket, and makes the connection hole wall of the front bracket fit with the outer wall of the positioning column 5, and then the spot facing tool performs spot facing processing on the end surface of the connection hole. The support mechanism 3 and the tightening mechanism 4 are respectively located at the two ends of the support 2 and the positioning column 5, and the support mechanism 3 provides a certain support force to the base end of the engine rear bracket, which is conducive to reducing the force of the tightening mechanism 4, and ensures that after the tightening mechanism 4 is pressed against the top of the front bracket end of the engine rear bracket, the connection hole wall of the front bracket fits with the outer wall of the positioning column 5, that is, the axis of the connection hole to be spot faced is vertical, which is conducive to ensuring the quality of the workpiece spot facing.

[0021] The axis of the clamping part of the clamping mechanism 4 is not higher than the upper surface of the positioning column 5, and the clamping part of the clamping mechanism 4 is located between two adjacent positioning columns 5. After the clamping mechanism 4 applies a force to the top of the front bracket, under the limiting action of the external force of the clamping mechanism 4 and the positioning column 5, the connecting hole wall of the front bracket is ensured to fit with the outer wall of the positioning column 5, so that the axis of the connecting hole to be spotfaced is vertical, which is convenient for the processing of the spotface tool.

[0022] The clamping mechanism 4 includes a clamping rod, which is threadedly connected to the base 1, has a simple structure, is easy to operate, and is convenient for the clamping mechanism 4 to apply a force to the front bracket end of the engine rear bracket.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
