Engine box body positioning structure

Abstract

The invention discloses an engine box body positioning structure which comprises a supporting base and a shielding plate. A positioning base is connected to the supporting base. A locking rod is connected to the positioning base. A locking rod elastic part is also arranged on the positioning base. A shielding extension section is further arranged at the side end of the shielding plate. A locking groove capable of being matched with a locking block is formed in the bottom end of the shielding plate. The locking groove is formed in the manner that an opening is small and an inner cavity is large. The locking block can penetrate through the opening of the locking groove to be located in the inner cavity of the locking groove. The locking block can rotate in the inner cavity of the locking groove. According to the structure, by arranging the locking rod and the shielding plate, the shielding plate can be locked to the top end of a shell box body only by moving and rotating the locking rod,in this way, the shell box body can be positioned, the shielding plate can also be positioned, and the situation that the shell box body and the shielding plate move accidentally is avoided. By meansof cooperation between a magnetic part and a metal part, positioning stability can be further improved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine casing positioning structure. Background technique [0002] The engine is a device that provides power. In order to ensure the stability of the engine operation, the engine is usually placed in the engine casing, which has the effects of shock resistance, heat dissipation, and noise reduction. Taking a motorcycle engine as an example, the engine housing includes a housing case and a housing case cover connected to the outside of the housing case. During the production and processing of the engine casing, the surface needs to be sprayed (spraying primer, topcoat, etc.). Since the casing box is located in the middle position, when spraying, only the peripheral surface of the casing box needs to be treated. That's it. [0003] Such as figure 1 Shown is a schematic structural diagram of the housing box, which has a housing chamber, a housing connection throug...

AI Technical Summary

Problems solved by technology

[0004] The existing spraying operation method is to place the shell box on the pallet (the through hole of the box body is located at the top position), and then place the cover plate adapted to the top of the shell box on the shell box to cover the box connection. The through hole, the shutter also has an extension section that can cover the through hole of the box body, and then it is sprayed, but this method has the following problems: 1. Since no positioning structure is provided, the shell box body only It is placed on the pallet by its own weight, and the spraying has a certain impact force. During the spraying process, it is very easy to move the housing box. In the lightest case, the paint will be sprayed into the housing cavity of the box body to cause pollution, and in the worst case, the housing box will be damaged. body detached from the pallet and damage the enclosure

2. The shroud is placed directly on the housing box without a locking structure. During the spraying process, the shroud is also easily moved due to the impact force, causing the problem that the paint is sprayed into the housing cavity

3. After the spraying treatment, the paint on the shell box will be dried, and the adhesion problem will occur at the connection between the shell box and the pallet due to the drying of the paint, which is not conducive to the cutting work of the shell box
