The purpose of the invention is: the electrophoresis tool is passed to the simple two-point engine hood, which can be respectively supported from two sides in an adjustable manner, and effectively ensures that the height difference of the two opposite fenders at the front side and the rear side of electrophoresis is within a small range.

In order to solve the technical problem, the invention provides a simple two-point engine cover electrophoresis tool.

The simple two-point type engine hood electrophoresis passing tool comprises a supporting bolt, a nut, a gasket, a steel pipe, a stop block and a handle, wherein the nut is in threaded connection with the outer wall of the middle section of the supporting bolt, the steel pipe is connected to the outer peripheral wall of the nut in a sleeved mode, the gasket is connected to the outer peripheral wall of the steel pipe in a sleeved mode, the stop block is also connected to the outer wall of the steel pipe in a fastened mode and located below the gasket, the handle is installed on the peripheral wall of the tail end, the lower section or the position close to the tail end of the supporting bolt, and the top end of the supporting bolt is an abutting end with a smooth curved surface.

As a preferable aspect of the present invention, the abutting end is in a ball-head shape.

As a preferable aspect of the present invention, the stay bolt is provided with an annular shoulder below the abutting end.

As a preferable scheme of the invention, the periphery of the gasket is provided with standard tooth shapes in an equidistant distribution mode.

As a preferable aspect of the present invention, the handle is a straight bar vertically connected to the end of the supporting bolt.

Compared with the prior art, the simple two-point engine hood electrophoresis passing tool has the beneficial effects that: the height difference of the left and right opposite fenders of the engine hood can be conveniently adjusted to be less than or equal to 1.0mm, the structure is simplified, welding and manufacturing can be performed through simple auxiliary materials, the processing is simple, and the materials are easy to obtain and low in cost.

fig. 2 is a schematic structural diagram of an embodiment of the present invention applied to the installation of a vehicle body frame.

Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "mounted," "connected," and "connected" are used broadly and are defined as, for example, either fixedly connected, detachably connected, or integrally connected, unless otherwise explicitly stated or limited; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the description of the present invention, it is to be further understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the machine or element being referred to 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 engine hood electrophoresis tool according to an embodiment of the present invention includes a support bolt 1, a nut 2, a gasket 3, a steel pipe 4, a stopper 5 and a handle 6, wherein the nut 2 is in threaded connection with an outer wall of a middle section of the support bolt 1, the steel pipe 4 is sleeved and connected to an outer circumferential wall of the nut 2, the gasket 3 is sleeved and connected to an outer circumferential wall of the steel pipe 4, the stopper 5 is also fastened and connected to an outer wall of the steel pipe 4 and located below the gasket 3, the handle 6 is installed on a circumferential wall at or near a terminal end, a top end of the support bolt 1 is an abutting end 11 having a smooth curved surface, when in use, two engine hood electrophoresis tools are installed from top to bottom on left and right side beams of a front cabin of a body frame, and installed as engine hood block buffer installation holes, the gasket 3 is placed on the boundary beam in a laminating manner, the gasket 3 supports the steel pipe 4 and the nut 2 and the supporting bolt 1 are supported, meanwhile, the stop block 5 and the clamping groove or the concave-convex part of the buffer block mounting hole on the boundary beam are clamped or the rotating position is limited, when the inner plate of the engine cover is supported and abutted by the abutting ends 11 of the supporting bolts 1 of the two tools, the supporting bolt 1 is driven to rotate by the handles 6 of the two tools, the stop block 5 is limited to enable the steel pipe 4 and the nut 2 not to rotate, so that the supporting bolt 1 adjusts the height by rotating, the height difference between the engine cover and the left and right wing panels is checked, the handle 6 is used for continuous adjustment, the height difference between the engine cover and the wing panels is 0 +/-1 mm, the state is kept changed for electrophoresis, the tools are taken down until the electrophoresis is finished, and a larger left and right difference between the wing panels cannot be formed after the electrophoresis is baked, the adjustment is also easy after hardening, the abutting end 11 can be in an arc 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.

Referring to fig. 1 or 2, the abutting end 11 is exemplarily in a ball-end shape, the ball-end shaped abutting end 11 can abut against the engine hood well at different height positions by using a round-end shape, and the abutting end 11 can also be in an elliptical head shape, a semicircular head shape, and the like.

Referring to fig. 1 or 2, for example, the supporting bolt 1 is provided with an annular shoulder 12 below the abutting end 11, and the annular shoulder 12 constitutes a gear, so that the supporting bolt 1 can be prevented from moving down excessively along the nut 2, and the engine cover is prevented from being in an excessively low position.

Referring to fig. 1 or 2, the gasket 3 is provided with standard tooth shapes at equal intervals, so that the gasket 3 can be conveniently fixed by a tool without clamping the vehicle body part by abutting the stop 5, and the supporting bolt 1 can be lifted and lowered by rotation.
