Description

Technical Field

[0001] The utility model belongs to the field of weld milling, and in particular relates to a special machine for milling welds on the upper and lower surfaces of a battery box frame of a new energy vehicle. Background Art

[0002] There will be welds on the upper and lower surfaces of the battery box frame of new energy vehicles. The unevenness of the welds will affect the flatness of the surface of the battery box frame, thereby affecting the sealing effect of the battery box. Therefore, the welds must be polished.

[0003] In the prior art, two methods are generally used to perform weld leveling.

[0004] One is to use manual grinding, which will produce a lot of debris and dust, which may cause explosions, affect production safety, and also affect the health of workers.

[0005] The other method is to use a milling machine to mill the weld. Generally, standard machine tools occupy a large area and cannot meet the requirements of production rhythm. The time for installing the workpiece before processing and removing the workpiece after processing is wasted, and efficiency is reduced. Utility Model Content

[0007] Preferably, the linkage tooling is driven by a set of screw guide rail assemblies, one of which is in the loading and unloading area to load materials and wait for processing, and the other is in the processing area for processing.

[0008] Preferably, the three-axis spindle slide is L-shaped, and an upper spindle and a lower spindle are arranged on the three-axis spindle slide. The upper spindle tool is slidably connected to the side of the upper spindle close to the bed, and the lower spindle tool is slidably connected to the side of the lower spindle close to the bed.

[0019] like Figure 1 As shown in FIG. 3 , a specific implementation method of a special machine for milling weld seams on the upper and lower surfaces of a battery box frame for a new energy vehicle is as follows:

[0020] It includes a bed 1, the middle of the bed 1 is a processing area 11, both sides of the bed 1 are loading and unloading areas 12, a pair of linkage tooling 3 is slidably connected to the bed 1, the linkage tooling 3 moves on the bed at the same time, driven by a set of screw guide rail assemblies, one is in the loading and unloading area 12 to load materials and wait for processing, and the other is in the processing area 11 for processing, so the production efficiency is high and the beat requirements are met.

[0021] A clamping mechanism 4 is provided on both sides of the two linkage toolings 3 parallel to the bed 1, and the clamping mechanism 4 clamps the battery box frame of the new energy vehicle to be processed. The two sides of the processing area 11 are rigidly connected with a three-axis spindle slide 2, respectively. The rigid connection meets the overall rigidity requirements and ensures the movement accuracy of the spindle. A milling device is installed in the three-axis spindle slide 2;

[0022] The three-axis spindle slide 2 is L-shaped, and an upper spindle 23 and a lower spindle 21 are arranged on the three-axis spindle slide 2. The upper spindle 23 is slidably connected to an upper spindle tool 24 on one side close to the bed 1, and the lower spindle 21 is slidably connected to a lower spindle tool 22 on one side close to the bed 1. The four upper, lower, left and right welds of the workpiece can be milled simultaneously without turning over, thereby improving work efficiency.

[0023] The spindle tool is a diamond tool;

[0024] Deformation support columns and holes are reserved under the three-axis spindle platform. When necessary, new support columns are installed in the holes for additional support to ensure that the spindle platform does not deform.

[0025] A chip removal system 5 is provided on one side of one of the three-axis spindle slides 2 , and the chip removal system 5 is rigidly connected to the bed 1 .

[0026] The chip removal system 5 is screw driven. A pair of screws are arranged on both sides of the bed 1. They drive the chips on both sides to the same end of the bed 1, and then another screw perpendicular to the previous screw sends the chips on one side to the other side for discharge together. The chip removal system is integrated with the bed to save space.

[0027] During operation, the clamping mechanism 4 clamps the battery box frame of the new energy vehicle to be processed, and the screw guide assembly drives the linkage tooling 3. One of the two linkage tooling 3 is in the loading and unloading area 12 to load and wait for processing, and the other is in the processing area 11 for processing. The battery box frame of the new energy vehicle is processed by two three-axis spindle slides in the processing area;

[0028] The upper and lower spindle tools slide in the spindle to directly mill the four upper, lower, left and right welds of the workpiece at the same time. After milling is completed, the linkage tooling 3 is driven to drive the processed workpiece to the loading and unloading area 12. At the same time, the linkage tooling 3 on the other side drives the workpiece to be processed into the processing area 11 for processing. When processing on the other side, the processed workpiece is taken out and installed on the workpiece to be processed, and this reciprocating process is repeated.

[0029] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
