In order to solve the technical problems, the invention provides a simple two-point type engine hood electrophoresis tool.

The utility model provides a simple and easy two-point type engine hood crosses electrophoresis frock, includes supporting bolt, nut, gasket, steel pipe, dog and handle, the nut with supporting bolt's middle section outer wall threaded connection, the steel pipe is fit and is connected on the periphery wall of nut, the gasket fit is connected the periphery wall of steel pipe, just the dog also fastening connection is in on the outer wall of steel pipe and be located the below of gasket, the handle is installed on supporting bolt's the terminal, hypomere or the peripheral wall near the terminal, supporting bolt's top is the butt end that has smooth curved surface.

As a preferable mode of the invention, the abutting end is in a ball head shape.

As a preferred embodiment of the present invention, the support bolt is provided with an annular shoulder below the abutment end.

As a preferred embodiment of the invention, the periphery of the gasket is provided with standard tooth shapes in an equidistant distribution.

As a preferable scheme of the invention, the handle is a straight rod vertically connected with the tail end of the supporting bolt.

Compared with the prior art, the simple two-point engine hood electrophoresis tool has the beneficial effects that: the height difference of the left and right sides of the engine cover relative to the fender is not more than 1.0mm, the structure is simplified, the Jian Yifu material can be welded and manufactured, the processing is simple, and the material is easy to obtain and has low cost.

fig. 2 is a schematic structural view of an embodiment of the invention in a vehicle body frame mounting application.

Detailed Description

The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.

In the description of the present invention, it should be understood that the terms "mounted," "connected," and "connected" are to be construed broadly in this application, and may be either fixedly connected, detachably connected, or integrally connected, for example, unless otherwise explicitly stated and defined; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

In the description of the present invention, it should be further understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention and to simplify the description, and do not indicate or imply that the machine or element in question must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

Referring to fig. 1 and 2, a simple two-point type engine hood electrophoresis tool according to the embodiment of the invention comprises a supporting bolt 1, a nut 2, a gasket 3, a steel pipe 4, a stop 5 and a handle 6, wherein the nut 2 is in threaded connection with the middle outer wall of the supporting bolt 1, the steel pipe 4 is sleeved on the outer peripheral wall of the nut 2, the gasket 3 is sleeved on the outer peripheral wall of the steel pipe 4, the stop 5 is also fixedly connected on the outer wall of the steel pipe 4 and is positioned below the gasket 3, the handle 6 is arranged on the tail end, the lower section or the peripheral wall near the tail end of the supporting bolt 1, the top end of the supporting bolt 1 is provided with a butt end 11 with a smooth curved surface, when in use, the two engine hood electrophoresis tools are respectively arranged on left and right side beams of a front cabin of a vehicle body frame from top to bottom, the mounting hole is a hood buffer block mounting hole, the gasket 3 is placed on the side beam in a fitting way, the gasket 3 supports the steel pipe 4 so as to carry the nut 2 and the supporting bolt 1, meanwhile, the stop block 5 is clamped with or limited to the rotation position of a clamping groove or a concave-convex part of the buffer block mounting hole on the side beam, when the inner plate of the hood is supported and abutted by the abutting ends 11 of the supporting bolts 1 of two tools, at the moment, the supporting bolts 1 are driven to rotate respectively through the handles 6 of the two tools, meanwhile, the stop block 5 is limited so that the steel pipe 4 and the nut 2 do not rotate, thereby, the supporting bolts 1 can be adjusted in height through rotation, the difference between the hood and the left and right fender surfaces is checked, the height of the hood and the fender surfaces is continuously adjusted through the handles 6, the state is kept for electrophoresis until the tools are taken down after electrophoresis, the electrophoresis baking device has the advantages that the electrophoresis baking device can not form a large difference of surface relative to the fender part, the adjustment is easy after hardening, the abutting end 11 can be in an arc-shaped surface shape or other shapes, so that the engine hood can be well supported at any angle without damaging the surface of the inner plate, the tool structure is simple, the simple auxiliary material welding or processing can be realized, the material is easy to obtain, and the cost is low.
