Description

M6 and M10 bolt quick adapter

technical field

The utility model relates to the field of automobile frame production, in particular to an M6 and M10 bolt quick conversion joint.

Background technique

A lot of nuts will be welded in the welding parts of the automobile subframe, and the subframe needs electrophoresis treatment. During the electrophoresis process, the protection of the nuts is not in place. After electrophoresis, there will be electrophoresis liquid in the nut threads, which affects the general purpose of the bolts. It can be assembled and shipped after entering and returning teeth. The most commonly used nuts in the subframe are M6 and M10. Because they are two types, different bolts are required for back threading. However, if the bolts are different, two pneumatic tightening guns need to be configured, so it is necessary to constantly replace the pneumatic tightening. guns, resulting in low production efficiency and rising production costs. In addition, whether M6 or M10 bolts are external hexagon or internal hexagon, when only one pneumatic tightening gun is configured, the tightening head of the tightening gun needs to be loosened or tightened every time it is replaced, which wastes the production cycle.

Utility model content

The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a M6 and M10 bolt quick conversion joint.

The purpose of this utility model is accomplished through the following technical solutions: this M6 and M10 bolt quick conversion joints mainly include M10 outer hexagon bolts, outer hexagon wrenches, connecting blocks, tightening heads, M6 inner hexagon bolts, M10 outer hexagon bolts Protrude into the hollow connection block, the outer diameter of the M10 outer hexagon bolt is connected with the left end of the connection block, and the M10 outer hexagon bolt is opened in the middle and connected with the outer hexagon wrench. In the flange surface, the M6 socket head cap bolts pass through the middle hole of the tightening head, and the M6 socket head cap bolts are threaded to connect the tightening head, and the left end of the tightening head is threaded to connect the right end of the block.

The outer end of the tightening head is rolled.

The beneficial effects of the utility model are as follows: after the utility model is used, the outer hexagonal flange of M6 thread M10 can use the same tightening gun as the M10 outer hexagonal bolt, and only one tightening gun is required to realize the two specifications of bolts, and the The two specifications of bolts can be quickly switched, which greatly speeds up the operation efficiency and improves the production efficiency.

Description of drawings

FIG. 1 is a schematic cross-sectional view of the structure of the utility model.

Reference numeral description: M10 outer hexagon bolt 1, outer hexagon wrench 2, connecting block 3, tightening head 4, M6 inner hexagon bolt 5.

Detailed ways

The present utility model will be described in detail below in conjunction with the accompanying drawings:

Example: As shown in the attached drawings, this M6 and M10 bolt quick conversion joint mainly includes M10 outer hexagon bolt 1, outer hexagon wrench 2, connecting block 3, tightening head 4, M6 inner hexagon bolt 5, M10 outer hexagon bolt 1. Extend into the hollow connection block 3. The outer diameter of the M10 outer hexagon bolt 1 is threaded with the left end of the connection block 3. The M10 outer hexagon bolt 1 has a hole in the middle and is connected to the outer hexagonal wrench 2. The extension of the outer hexagonal wrench 2 is just enough In the hexagon socket flange surface of the M6 socket head cap bolt 5, the M6 socket head cap bolt 5 passes through the middle hole of the tightening head 4, and the M6 socket head cap bolt 5 is threadedly connected to the tightening head 4, and the left end of the tightening head 4 is connected to the right end of the block 3 through a threaded connection . The outer end of the tightening head 4 is rolled. The utility model realizes that the outer hexagon flange of M6 thread M10 can be used with the same tightening gun as the M10 outer hexagon bolt. Bolt 5.

It can be understood that, for those skilled in the art, equivalent replacements or changes to the technical solutions and concept of the present invention should fall within the protection scope of the appended claims of the present invention.
