FIG. 2 is an enlarged view of area A of FIG. 1;

fig. 3 is a combination view of a locating post, a chassis and a mounting post.

Detailed Description

The present invention will be described in further detail with reference to the drawings and the detailed description.

As shown in fig. 1 to 3, the welding and fixing device for the battery tray mounting block of the present invention includes a mounting base 10, a groove 11 and a positioning hole 12 are disposed on an upper surface of the mounting base 10, the positioning hole 12 is a cylindrical hole, an axis of the positioning hole 12 is vertically disposed, the groove 11 and the positioning hole 12 are disposed side by side, a positioning column 13 is vertically disposed on a bottom surface of the groove 11, an opening portion is disposed on one side surface of the groove 11, a positioning block 14 is detachably mounted on the mounting base 10, specifically, the positioning block 14 is mounted on the mounting base 10 by a bolt, and a fastening portion 141 is disposed on an upper portion of the positioning block 14.

When the positioning block 14 is mounted on the mounting seat 10, the positioning block 14 seals the opening of the groove 11, and the buckling part 141 of the positioning block 14 is positioned in the groove 11, so that the positioning block 14 can be detached from the mounting seat 10 after the battery tray mounting block is welded and fixed.

A pressing block 20 is further arranged above the mounting seat 10, and the pressing block 20 can be driven by a driving mechanism to press downwards, so that after the battery tray mounting block is positioned and placed on the mounting seat 10, the pressing block 20 presses downwards to tightly fix the battery tray mounting block on the mounting seat 10.

A metal sleeve 121 is sleeved in the positioning hole 12, so that when the convex column of the mounting block is inserted into the positioning hole 12, the convex column of the mounting block is in sliding fit with the metal sleeve 121, and the resistance is small.

The bottom surface of the groove 11 is provided with a mounting hole, the positioning column 13 is vertically arranged on the upper surface of a chassis 131, the lower surface of the chassis 131 is vertically provided with a mounting column 132, and the mounting column 132 is used for being inserted into the mounting hole in the bottom surface of the groove 11, so that when the positioning column 13 needs to be replaced, the mounting column 132 can be pulled out from the mounting hole in the bottom surface of the groove 11, and the positioning columns 13 with different sizes can be replaced when needed.

The positioning column 13 is provided with a central through hole 133 axially penetrating through the positioning column 13, that is, the central through hole 133 penetrates through and extends to the upper end face of the positioning column 13, a gas passage communicated with the central through hole 133 is arranged on the mounting seat 10, and the gas passage is communicated with a high-pressure gas source, so that after the welding and fixing of the battery tray mounting block are completed, the high-pressure gas source is opened, the high-pressure gas source can convey high-pressure gas to the central through hole 133, the high-pressure gas is blown out from the upper end face of the positioning column 13, and the battery tray mounting block can be blown upwards so as to take off materials.

The above description is only about the preferred embodiment of the present invention, but it should not be understood as limiting the claims, and the present invention may be modified in other structures, not limited to the above structures. In general, all changes which come within the scope of the utility model as defined by the independent claims are intended to be embraced therein.
