Description

Technical Field

[0001] The present invention relates to the technical field of battery box processing, and in particular to a milling mechanism for processing a battery box. Background Art

[0002] In electric vehicles, the weight of the power battery pack accounts for about 30% of the total vehicle mass. The lightweighting of the vehicle and the endless pursuit of the energy density of the power battery system have put forward requirements for the lightweight design of the battery pack structure. Inside the battery pack system, the box is the largest structural component. If its weight is reduced, the energy density can be significantly improved. Under the premise of structural optimization and re-optimization, the use of new materials is the fundamental way to lightweight the battery box.

[0003] According to the publication number "CN110227849A", a milling cutter used for processing the side grooves of the bottom plate of a battery box includes a shank and a milling cutter body installed on the shank, and also includes a leveling assembly. Two sets of leveling assemblies are arranged, and the two sets of leveling assemblies are symmetrically assembled on the upper and lower sides of the milling cutter body. The leveling assembly is provided with a leveling needle support plate, a leveling needle limiting plate and a leveling needle. The leveling needle support plate is connected to the leveling needle limiting plate. The leveling needle is assembled between the leveling needle support plate and the leveling needle limiting plate. The leveling needle can rotate relative to the leveling needle support plate, etc.

[0004] In the prior art, when milling a battery box, a large amount of metal chips will be left on the processing table. As the workpiece and the milling cutter are cooled by flushing, some metal chip ash will easily flow out of the processing table with the water flow, making it inconvenient to collect them collectively. At the same time, the unevenness of the processing table surface affects the levelness of the battery box, resulting in inaccurate milling of the product. Summary of the invention

[0005] The purpose of the present invention is to solve the following shortcomings in the prior art. When the battery box is milled in the prior art, a large amount of metal chips will be left on the processing table. As the outside world uses flushing to cool the workpiece and the milling cutter, some metal chip ash will easily flow out of the processing table with the water flow, making it inconvenient to collect them collectively. At the same time, it affects the unevenness of the processing table surface and the horizontality of the battery box, resulting in inaccurate product milling. A milling mechanism for battery box processing is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A milling mechanism for processing a battery box, comprising a box body and a vertical plate, wherein the vertical plate is fixedly connected to one side of the box body, and a milling cutter is installed on the vertical plate;

[0008] A cleaning component is installed on the box body, and the cleaning component includes a push plate, a sleeve, a rotating shaft, a rack plate, and a filter screen.

The two push plates are slidably connected to the upper surface of the box body and are located on both sides of one end of the through-hole. One end of the sleeve is fixedly connected to the push plate, and a thread is opened on the inner side wall of the sleeve. One end of the rotating shaft is threadedly connected to the sleeve, and a tooth pattern is opened at the end of the rotating shaft away from the sleeve. The rotating shaft is meshed and connected with the rack plate, and the filter screen is fixedly connected in the through-hole;

[0009] A transverse plate is fixedly connected to the box body, a fixed plate is fixedly connected to the transverse plate, moving rods are slidably connected to both ends of the fixed plate, an extrusion plate is fixedly connected between the two moving rods, and the extrusion plate is slidably connected to the upper surface of the box body.

[0010] Preferably, the cleaning component further comprises a placement plate and a pull rod, wherein the placement plate is slidably connected in the through opening, and the pull rod is hinged between the bottom end of the push plate and the upper end of the placement plate.

[0011] Preferably, one end of the two moving rods away from the extrusion plate is fixedly connected to a first spring, the first spring is fixedly connected to the fixing plate, and a through groove is formed on the fixing plate.

[0012] Preferably, a cam is rotatably connected to the transverse plate, a servo motor is fixedly connected to the lower end of the cam, and the servo motor is fixedly connected to the outer surface of the box body.

[0013] Preferably, both ends of the extrusion plate are fixedly connected to the rack plate respectively, and the extrusion plate is arranged on one side of the push plate.

[0014] Preferably, both sides of one end of the through opening on the box body are respectively fixedly connected with limiting plates, and the limiting plates are arranged on the lower side of the placement plate.

[0015] Preferably, a square cavity is fixedly connected to the upper surface of the box body, a plurality of sliding rods are slidably connected to both ends of the square cavity, and a second spring is fixedly connected between one end of the sliding rod and the inner wall of the square cavity.

[0017] Preferably, the placement plate is arranged in a convex shape, and the placement plate is arranged directly below the milling cutter.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-Figure 4 A milling mechanism for processing a battery box, comprising a box body 1 and a vertical plate 8, wherein the vertical plate 8 is fixedly connected to one side of the box body 1, and a milling cutter 9 is installed on the vertical plate 8;

[0029] A cleaning component is installed on the box body 1, and the cleaning component includes a push plate 6, a sleeve 17, a rotating shaft 12, a rack plate 13, and a filter screen 15. The two rack plates 13 are respectively slidably connected to the two ends of the upper surface of the box body 1, and an L-shaped through-hole is opened in the box body 1. The two push plates 6 are slidably connected to the upper surface of the box body 1 and are located on both sides of one end of the through-hole. One end of the sleeve 17 is fixedly connected to the push plate 6, and a thread is opened on the inner wall of the sleeve 17. One end of the rotating shaft 12 is threadedly connected in the sleeve 17, and a tooth pattern is opened at the end of the rotating shaft 12 away from the sleeve 17. The rotating shaft 12 is meshed and connected with the rack plate 13, and the filter screen 15 is fixedly connected in the through-hole. The cleaning component also includes a placement plate 16 and a pull rod 18. The placement plate 16 is slidably connected in the through-hole. The placement plate 16 is set in a convex shape. The placement plate 16 is set on the lower side of the milling cutter 9. The two sides of one end of the through-hole on the box body 1 are respectively fixed A limit plate 19 is connected, and the limit plate 19 is arranged on the lower side of the placement plate 16. The limit plate 19 is used to limit the downward movement distance of the placement plate 16. The pull rod 18 is hinged between the bottom end of the push plate 6 and the upper end of the placement plate 16. As the two push plates 6 move in the center, the placement plate 16 is pushed up by the pull rod 18. At this time, the placement plate 16 can push the processed battery box to move up, which is convenient for the staff to take away the battery box on the placement plate 16. The center movement of the two placement plates 16 can push the water and metal chips on the surface of the workbench into the through hole on the box body 1, and the water is discharged and collected through the other end of the through hole. The metal chips will be subject to the resistance of the filter screen 15 and remain in the through hole for collection, thereby realizing the separation of water and metal chips. At the same time, it can avoid the appearance of metal chips on the workbench, which will cause the surface of the workbench to be uneven, affect the horizontality of the battery box of the processed part, and affect the inaccuracy of the processing.

[0030] The box body 1 is fixedly connected with a transverse plate 4, and a fixed plate 20 is fixedly connected with the transverse plate 4. Moving rods 14 are slidably connected at both ends of the fixed plate 20. An extrusion plate 5 is fixedly connected between the two moving rods 14. The extrusion plate 5 is slidably connected to the upper surface of the box body 1. A cam 3 is rotatably connected to the transverse plate 4. A servo motor 2 is fixedly connected to the lower end of the cam 3. The servo motor 2 is fixedly connected to the outer surface of the box body 1. The end of the moving rod 14 away from the extrusion plate 5 is fixedly connected with a first spring 21. The first spring 21 is fixedly connected to the fixed plate 20. When the cam 3 rotates in the opposite direction and no longer pushes the extrusion plate 5, the extrusion plate 5 can be reset to the left under the pulling force of the first spring 21. The reset of the extrusion plate 5 can pull the rack plate 13 The resetting movement, a through groove is provided on the fixed plate 20, and the through groove is used for the normal rotation of the cam 3. The two ends of the extrusion plate 5 are fixedly connected with the rack plate 13 respectively, and the extrusion plate 5 is arranged on one side of the push plate 6, driving the servo motor 2 and driving the cam 3 to rotate clockwise. The end of the cam 3 away from the servo motor 2 passes through the through groove on the fixed plate 20 to push the extrusion plate 5 to slide on the upper surface of the box body 1. When the extrusion plate 5 moves in the direction of the placement plate 16, it can pull the moving rod 14 to slide on the fixed plate 20 and stretch the first spring 21. When the cam 3 rotates in the opposite direction and no longer pushes the extrusion plate 5, the extrusion plate 5 can be reset under the pulling force of the first spring 21. The resetting of the extrusion plate 5 can pull the rack plate 13 to reset.

[0031] A square cavity 10 is fixedly connected to the upper surface of the box body 1, and multiple sliding rods 7 are slidably connected to both ends of the square cavity 10. A second spring 22 is fixedly connected between one end of the sliding rod and the inner wall of the square cavity 10. L-shaped plates 11 are fixedly connected to both ends of the square cavity 10. The L-shaped plate 11 is arranged on one side of the push plate 6. As the extrusion plate 5 moves toward the direction of the square cavity 10, the battery box on the placement plate 16 can be pushed to move toward the direction of the square cavity 10, and the sliding rod 7 can be pushed to slide on the side wall of the square cavity 10 and squeeze the second spring 22. The sliding rod 7 can be squeezed according to the shape of the battery box, and the remaining sliding rods 7 can limit the battery box to the left and right.

[0032] When the push plate 6 moves with the sleeve 17, the placement plate 16 is pulled downward by the pull rod 18. When the extrusion plate 5 moves toward the direction of the square cavity 10, the battery box on the placement plate 16 can be pushed to move toward the direction of the square cavity 10, and the slide bar 7 can be pushed to slide on the side wall of the square cavity 10 and squeeze the second spring 22. The slide bar 7 can be squeezed according to the shape of the battery box. The remaining slide bars 7 can limit the battery box to the left and right. At the same time, the movement of the extrusion plate 5 can squeeze the battery box to achieve precise fixation before processing.

[0033] When the battery box needs to be taken out, the driving cam 3 rotates in the opposite direction and no longer pushes the extrusion plate 5. Since the servo motor 2 can control the cam 3 to rotate clockwise or counterclockwise, the effect of controlling the servo motor 2 to drive the cam 3 to rotate in the opposite direction is that the cam 3 no longer has an extrusion force on the driving plate 5, so the extrusion plate 5 can be reset and no longer has a clamping force on the battery box, which is convenient for taking out the battery box and subsequent processing of the battery box. The extrusion plate 5 can be reset under the pulling force of the first spring 21, and the rotating shaft 12 is pulled by the rack plate 13 to rotate in the opposite direction. At this time, the two sleeves 17 and the push plate 6 move in the center. As the two push plates 6 move in the center, the placement plate 16 is pushed up by the pull rod 18 respectively, which is convenient for the staff to take away the battery box on the placement plate 16. At the same time, the centering movement of the two push plates 6 can push the water and metal chips on the surface of the workbench into the through-port on the box body 1, and the water is discharged and collected through the other end of the through-port. The metal chips will be resisted by the filter screen 15 and left in the through-port for collection.
