Then the tool is placed in the battery shell, the front end positioning plate and the front end of the battery shell are subjected to profiling positioning, the rear end positioning plate fixes the left module beam and the right module beam and is attached to the section bar face of the module beams, and the limiting block is just clamped between the left module beam and the right module beam; if the left module beam and the right module beam are placed reversely, the rear end plate cannot be attached to the sectional material, the limiting block cannot be placed between the left cross beam and the right cross beam, and therefore it is guaranteed that the left module beam and the right module beam cannot be assembled mistakenly.

Description

TECHNICAL FIELD

[0001] The utility model relates to new energy automobile battery case manufacturing technical field, especially a new energy automobile battery case module beam mistake proof installation tool. BACKGROUND

[0002] The existing battery case internal module beam is many in quantity, small in difference and similar in part, in the actual production process, the assembly of the module beam is mostly bolt fastening, the hole on the module beam is corresponded with the screw hole inside the battery case, the bolt is locked into the screw hole inside the battery case through the hole on the module beam, in the operation process, the differentiation of the module beam only relies on personnel visual inspection, and the wrong assembly phenomenon is prone to occur, and the inspection personnel of the subsequent process finds the wrong assembly and then reworks, which is time-consuming and laborious. As shown in figure 1, the left module beam 1 and the right module beam 3 only differ in length size by several millimeters, and are difficult to distinguish in other aspects, and are extremely prone to mixed assembly.Therefore, the industry urgently needs a new energy automobile battery case module beam mistake proof installation tool. INVENTION CONTENTS

[0003] The utility model discloses a new energy automobile battery case module beam mistake proof installation tool, which can prevent the left module beam and the right module beam from being wrongly assembled.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A new energy automobile battery case module beam mistake proof installation tool, which comprises a handle, a positioning pin, a support, a front end positioning plate, a rear end positioning plate, a limiting block, the front end positioning plate and the rear end positioning plate are arranged at the two ends of the support, the handle is installed on the support, the limiting block is installed below the middle part of the rear end positioning plate, a left profiling groove and a right profiling groove are arranged on the rear end positioning plate, and holes for inserting the positioning pin are arranged on the front end positioning plate and the rear end positioning plate.

[0006] The holes for inserting the positioning pin on the front end positioning plate and the rear end positioning plate correspond to the hole positions on the battery case, and the center lines are on a straight line.

[0007] The left profiling groove and the right profiling groove correspond to the outer shape and size of the left module beam and the right module beam respectively.

[0008] The utility model has the following advantages:

[0009] During battery casing manufacturing, fastening bolts are used to install the left and right module beams. The process involves first placing the left and right module beams into their corresponding positions on the battery casing, then placing this fixture inside the casing. The front positioning plate is positioned to conform to the front of the battery casing, and the rear positioning plate fixes the left and right module beams and fits against the module beam profile surface. The limiting block is precisely inserted between the left and right module beams. If the left and right module beams are placed in reverse, the rear plate cannot fit against the profile, and the limiting block cannot be inserted between the left and right crossbeams. This ensures that the left and right module beams are not misassembled. Attached Figure Description

[0010] Figure 1 This is a three-dimensional schematic diagram of the present invention before it is placed inside the battery casing;

[0011] Figure 2 This is a perspective view of the present invention placed inside a battery casing, without showing the battery casing itself.

[0012] The labels in the diagram represent: 1. Left module beam, 2. Handle, 3. Right module beam, 4. Battery casing, 5. Positioning pin, 6. Bracket, 7. Front positioning plate, 8. Rear positioning plate, 9. Limiting block, 8-1. Left contour groove, 8-2. Right contour groove. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] This utility model provides a fault-prevention installation fixture for a new energy vehicle battery casing module beam, such as... Figure 1 As shown, the fixture includes a handle 2, a positioning pin 5, a bracket 6, a front positioning plate 7, a rear positioning plate 8, and a limiting block 9. The bracket 6 has a front positioning plate 7 and a rear positioning plate 8 at both ends. The outer shape of the front positioning plate 7 is similar to the structural shape at the end of the battery case. The rear positioning plate 8 has a left contour groove 8-1 and a right contour groove 8-2, which correspond to the outer shape and size of the left module beam 1 and the right module beam 3, respectively. The limiting block 9 is installed in the lower middle part of the rear positioning plate 8. The front positioning plate 7 and the rear positioning plate 8 both have holes for inserting the positioning pin 5. The positioning pin 5 is used to position this fixture.

[0015] This utility model discloses a mis-installation fixture for a new energy vehicle battery housing module beam. The working principle is as follows: First, place the left module beam 1 and right module beam 3 inside the battery housing 4 at their intended installation positions. Then, holding the handle 2, place the fixture inside the battery housing, ensuring the front positioning plate 7 fits snugly against the structure at the end of the battery housing. The rear positioning plate 8 fixes the left module beam 1 and right module beam 3 and fits snugly against the module beam profile surface. The rear positioning plate 8 has a limiting block 9, which fits precisely between the left module beam 1 and right module beam 3. Figure 2As shown, so that the installation is correct; if the left module beam 1, right module beam 3 position placement is reversed, the rear end positioning plate 8 cannot be attached to the profile, the limiting block cannot be put in, which proves that the placement is wrong and cannot be installed. After placing in place, the front end positioning plate 7 of the tool is completely attached to the end of the battery shell, and the rear end positioning plate 8 is completely attached to the left module beam 1 and the right module beam 3. At this time, the positioning pin 5 is inserted, and then the left module beam 1 and the right module beam 3 are fastened and fixed using the installation bolt, and the installation is completed.
