Description

Technical Field

[0001] The present invention relates to the field of milling technology, and in particular to a milling device for processing a battery tray for a new energy vehicle. Background Art

[0002] The battery tray of new energy vehicles is the core load-bearing structure of the battery system. It has functions such as protecting battery cells, heat dissipation management, and impact resistance. It directly affects the vehicle's endurance, safety, and lightweight level. The mainstream material used is aluminum alloy. Aluminum alloy is lightweight (low density), highly corrosion-resistant, and has mature processing technology. Milling is used to ensure flatness.

[0003] For example, the patent with the authorization announcement number CN116786874B and the authorization announcement date December 5, 2023, and the name is "A fully automatic double-sided milling device for a battery tray", includes a fixed table, which is hollow and has a dual-axis motor 1 fixedly connected to the inner bottom wall. The two output shaft ends of the dual-axis motor 1 are fixedly connected to a threaded rod 1, and the threads of the outer walls of the two threaded rods are arranged in opposite directions and are threadedly connected to a slider. The upper side wall of each slider is fixedly connected to a connecting block that movably passes through the side wall of the fixed table, and the upper end of each connecting block is fixedly connected to a movable column slidably arranged on the side wall of the fixed table. The outer wall of each movable column is provided with a movable milling mechanism. The present invention firmly clamps the battery tray through the splint and the suction cup, thereby ensuring the firmness and stability of the battery tray during milling, and uses two milling cutters to move up and down synchronously on both sides of the battery tray at the same time, thereby achieving the simultaneous milling of the welds on both sides of the battery tray, achieving the effect of double-sided milling, and improving the milling efficiency of the battery tray.

[0004] Although the above-mentioned fully automatic double-sided milling device can move up and down synchronously on both sides of the battery tray, thus realizing the simultaneous milling of the welds on both sides of the battery tray, when the depth, length and pressure of the simultaneous milling on both sides of the battery tray are different, it is easy to cause the battery tray to shake, resulting in the failure of the battery tray milling. In addition, the clamping mechanism of the above-mentioned fully automatic double-sided milling device cannot adjust the milling angle of the battery tray, making it difficult for the milling device to fully and accurately mill the plane to be milled of the battery tray.

[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a milling device for processing a battery tray for a new energy vehicle, comprising a base 1, a gantry frame 2 is provided on the upper end of the base 1, and further comprising:

[0037] The gantry frame 2 includes a ∩-shaped frame 20, wherein two slide rails 21 are provided at the lower end of the ∩-shaped frame 20, and the slide rails 21 are symmetrically arranged at the upper end of the base 1. A milling unit 22 is provided in the middle of the upper side of the ∩-shaped frame 20, and the milling unit 22 can move up and down in the vertical direction;

[0038] The clamp assembly 3 includes two brackets 30, each of which is arranged at the upper end of the base 1. A rotating shaft 31 is provided on the upper side of each bracket 30 in a rotatable manner. A clamping mechanism 32 is provided at one end of the two rotating shafts 31 close to each other. The clamping mechanism 32 clamps and fixes the edge of the battery tray through two sliding clamping claws 33. A driving mechanism 34 is provided at one end of each rotating shaft 31 away from the clamping mechanism 32. The driving mechanism 34 is used to drive the clamping mechanism 32 to rotate.

[0039] The cooling component 4 includes a cooling water pipe 40, which is arranged on one side of the milling unit 22. One end of the cooling water pipe 40 is connected to a cooling mechanism 41, and the cooling mechanism 41 is used to continuously transport coolant to the inside of the milling cutter of the milling unit 22. A cooling air duct 42 is provided on the other side of the milling unit 22, and the cooling air duct 42 is used to spray air flow to the milling unit 22.

[0040] In another embodiment provided by the present invention, a support plate 10 is provided at the middle of the upper end of the base 1, and a plurality of connecting rods 11 are symmetrically provided at the lower end of the support plate 10 through a hinge, and a threaded block 12 is hingedly connected to the end of each connecting rod 11 away from the support plate 10. Two sliding grooves 13 are symmetrically provided on the upper side of the base 1, and a first threaded rod 14 is rotatably provided in each sliding groove 13. The outer side of the first threaded rod 14 is symmetrically provided with opposite threads, and the threaded block 12 is provided on the outer side of the first threaded rod 14 by threaded engagement, and a first motor 15 is provided at one end of the first threaded rod 14;

[0041] The specific implementation is as follows: first, the edge of the battery tray is clamped and fixed by two clamping mechanisms 32. In order to prevent the battery tray from being separated from the clamping mechanism 32 due to excessive force during the milling process, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 drives the two threaded blocks 12 arranged thereon by threaded cooperation to move, thereby making the threaded block 12 drive the connecting rod 11 connected thereto to move, so that the connecting rod 11 adjusts the position height of the support plate 10, so that the support plate 10 can support and limit the lower end of the battery tray during the milling process according to the processing environment, and avoid the situation where the clamp assembly 3 is insufficiently fixed to the battery tray due to excessive pressure when the milling unit 22 is milling or drilling, resulting in milling failure. Specifically, when the milling unit 22 mills a plane or drills a hole on the battery tray, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 drives The two threaded blocks 12 arranged thereon are close to each other, so that the threaded blocks 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position height of the support plate 10, so that the support plate 10 rises and sticks to the lower end of the battery tray, so that the support plate 10 supports and limits the battery tray during milling and drilling, and prevents the battery tray from being subjected to excessive force and falling off the clamping mechanism 32; when the driving mechanism 34 drives the rotation adjustment through the clamping mechanism 32, the first motor 15 drives the first threaded rod 14 to rotate in the opposite direction, so that the first threaded rod 14 drives the two threaded blocks 12 arranged thereon to move away from each other, so that the threaded blocks 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 drives the support plate 10 to descend, so that the support plate 10 descends and moves away from the lower end of the battery tray, so that the support plate 10 makes room, which facilitates the driving mechanism 34 to drive the rotation adjustment through the clamping mechanism 32.

[0042] In another embodiment provided by the present invention, the driving mechanism 34 includes a driving motor 340, which is disposed in the middle of the upper side of the base 1. A first synchronous pulley 341 is disposed at the output end of the driving motor 340, and a second synchronous pulley 342 is disposed at the end of the rotating shaft 31 away from the clamping mechanism 32. The first synchronous pulley 341 and the second synchronous pulley 342 are connected by a synchronous belt 343.

[0043] The specific implementation method is as follows: when milling different surfaces of the battery tray, in order to avoid wasting processing time by manually flipping and re-fixing the battery tray, the battery tray is flipped by the driving mechanism 34. Specifically, the first threaded rod 14 is rotated in the opposite direction by the first motor 15, so that the first threaded rod 14 drives the two threaded blocks 12 arranged thereon to move away from each other, so that the threaded block 12 drives the connecting rod 11 to rotate and move, so that the connecting rod 11 drives the support plate 10 to descend, so that the support plate 10 descends and moves away from the lower end of the battery tray, so that the support plate 10 makes way for the position. At this time, the first synchronous wheel 341 is driven to rotate by the driving motor 340, so that the first synchronous wheel 341 drives the second synchronous wheel 342 to rotate synchronously through the synchronous belt 343. , so that the second synchronous wheel 342 drives the clamping mechanism 32 to rotate through the rotating shaft 31, so that the clamping mechanism 32 drives the battery tray to rotate through the clamping claw 33, so that the driving mechanism 34 flips instead of manual flipping, and there is no need to perform the re-fixing step when the driving mechanism 34 drives the battery tray to flip, thereby shortening the milling processing time of the battery tray, and after the battery tray is flipped, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 and the threaded block 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position height of the support plate 10, so that the support plate 10 rises again and sticks to the lower end of the battery tray, so that the support plate 10 supports and limits the battery tray during milling and drilling.

[0044] In particular, when the milling position of the battery tray is not in a horizontal position, that is, the milling position of the battery tray does not coincide with the horizontal plane, the first synchronous wheel 341 is driven to rotate by the driving motor 340, so that the first synchronous wheel 341 drives the second synchronous wheel 342 to rotate through the synchronous belt 343, so that the second synchronous wheel 342 drives the clamping mechanism 32 to rotate through the rotating shaft 31, so that the clamping mechanism 32 drives the battery tray to rotate at different angles, so that the clamping mechanism 32 adjusts the milling position of the battery tray to a horizontal position, so that the milling unit 22 can mill the milling position of the battery tray without replacing the fixture, thereby improving the applicability of the equipment; and at this time, the rotation of the mounting plate 320 is limited only by the driving mechanism 34, and the milling action when the battery tray is in a horizontal state is far more than the milling action when the battery tray is not in a horizontal position, so the mounting plate 320 is temporarily limited by the driving mechanism 34 to prevent the mounting plate 320 from rotating, thereby ensuring that the milling of the battery tray can be carried out normally.

[0045] In another embodiment provided by the present invention, the clamping mechanism 32 further includes a mounting plate 320, which is disposed at one end of the rotating shaft 31 away from the driving mechanism 34. A dual-output motor 321 is disposed in the mounting plate 320, and each output end of the dual-output motor 321 is provided with a second threaded rod 322. The second threaded rod 322 is rotatably disposed in the mounting plate 320, and the threads of the two second threaded rods 322 are arranged oppositely. Each second threaded rod 322 is provided with a connecting block 323 by threaded engagement, and each connecting block 323 is provided with a hydraulic telescopic rod 324, and each protruding end of the hydraulic telescopic rod 324 is provided with a clamping claw 33.

[0046] The specific implementation is as follows: the battery tray is placed on the support plate 10. When the battery tray is clamped, the two second threaded rods 322 installed at its two output ends are driven to rotate synchronously by the dual-output motor 321. Since the screw directions of the two second threaded rods 322 are set in opposite directions, the two second threaded rods 322 respectively drive the connecting blocks 323 set thereon to move in opposite directions, that is, the two connecting blocks 323 move away from each other. At this time, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 and the threaded block 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position height of the support plate 10, so that the support plate 10 lifts the battery tray to the same position height as the clamping claws 33, so that the battery tray enters between the clamping claws 33. After the battery tray enters between the clamping claws 33, the dual-output motor 321 drives the two second threaded rods 322 installed at its two output ends to rotate synchronously in the opposite direction, so that the two second threaded rods 322 can rotate synchronously in the opposite direction. The two threaded rods 322 respectively drive the connecting blocks 323 provided thereon to move in relative directions, that is, the two threaded blocks 12 approach each other, so that the clamping claw 33 approaches the corner of the battery tray. At this time, the clamping claw 33 is driven by the hydraulic telescopic rod 324 to move in the direction close to the battery tray, so that the clamping claw 33 approaches and fits the edge surface of the battery tray, so that the clamping claw 33 clamps and fixes the battery tray; after the battery tray is milled, under the premise that the support plate 10 supports the bottom of the battery tray, the two second threaded rods 322 are directly driven to rotate synchronously by the dual-output end motor 321, so that the two second threaded rods 322 respectively drive the connecting blocks 323 provided thereon to move away from each other, and at the same time, the hydraulic telescopic rod 324 drives the clamping claw 33 to move in the direction away from the battery tray, so that the clamping claw 33 is away from the battery tray, so that the clamping claw 33 releases the clamping fixation of the battery tray, thereby unloading the battery tray after milling.

[0047] In another embodiment provided by the present invention, the clamping claw 33 includes a moving block 330, which is slidably arranged in the mounting plate 320, and the moving block 330 is arranged at the protruding end of the hydraulic telescopic rod 324. An L-shaped plate 331 is slidably arranged in the moving block 330, and a wedge block 332 is slidably arranged on the L-shaped plate 331. The wedge block 332 is slidably arranged in the moving block 330, and a baffle 333 is provided on the outside of the L-shaped plate 331. A sliding rod 334 is provided on the moving block 330, and the sliding rod 334 is slidably arranged in the middle of the baffle 333. A return spring 335 is provided between the baffle 333 and the moving block 330, and the return spring 335 is sleeved on the outside of the sliding rod 334.

[0048] When the lever 330 is pressed against the top of the lever 331, the lever 332 is pressed against the top of the lever 331, and the lever 332 is pressed against the top of the lever 331. The pressure and sufficient fitting area clamp the battery tray firmly; in addition, when the L-shaped plate 331 slides along the moving block 330 to clamp the battery tray, the L-shaped plate 331 drives the baffle 333 to move synchronously along the sliding rod 334, so that the baffle 333 squeezes the return spring 335 to move closer to the moving block 330. When the battery tray is milled and unloaded, the hydraulic telescopic rod 324 drives the moving block 330 away from the battery tray. At this time, the return spring 335 drives the baffle 333 to move in the opposite direction and reset, so that the baffle 333 33 drives the L-shaped plate 331 to move in the opposite direction along the sliding block and reset, so that the L-shaped plate 331 squeezes the inclined surface of the wedge block 332, so that the wedge block 332 moves to the outside of the moving block 330 and resets, so that after the wedge block 332 and the L-shaped plate 331 are reset, it is convenient to clamp and fix the next battery tray to be milled. After the battery tray is clamped and fixed, the ∩-shaped frame 20 is driven to move by the slide rail 21, so that the ∩-shaped frame 20 drives the milling unit 22 to move, so that the milling unit 22 mills the battery tray.

[0049] In another embodiment provided by the present invention, a limiting groove is symmetrically provided at one end of the mounting plate 320 away from the rotating shaft 31, and two limiting pieces 3300 are symmetrically provided on a side of the movable block 330 close to the mounting plate 320. One limiting piece 3300 is slidably provided in each limiting groove.

[0050] The specific implementation method is: when the hydraulic telescopic rod 324 drives the moving block 330 to approach the battery tray, in order to prevent the moving block 330 from rotating during movement, a limiting plate 3300 that moves synchronously with the moving block 330 is set to slide in the limiting groove, so that the limiting plate 3300 and the limiting groove guide and limit the moving moving block 330 to ensure that the moving block 330 moves accurately.

[0051] In another embodiment provided by the present invention, the clamping mechanism 32 further includes two limiting rods 325, and two clamping blocks 326 are symmetrically provided on the limiting rods 325 in a sliding manner. The clamping blocks 326 are connected to the limiting rods 325 via limiting springs 327. Two arc-shaped grooves are symmetrically provided on the upper side of the bracket 30, and the limiting rods 325 are slidably disposed in the arc-shaped grooves.

[0052] The specific implementation is as follows: the limit rods 325 are symmetrically arranged on one side of the mounting plate 320 close to the bracket 30. When the mounting plate 320 is in a horizontal or approximately horizontal state, that is, when the milling position of the battery tray is in a horizontal or approximately horizontal state, the first motor 15 drives the mounting plate 320 to rotate through the first synchronous wheel 341, the synchronous belt 343 and the second synchronous wheel 342. The mounting plate 320 drives the two limit rods 325 to rotate synchronously around the rotating shaft 31, and the two limit rods 325 rotate around the rotating shaft 31. The trajectory of the two limit rods 325 passes through the arc groove when rotating around the rotating shaft 31. When the clamping mechanism 32 drives the battery tray to rotate to the specified position, when the limit rod 325 is in the arc groove, the battery tray is rotated to the specified position. When the battery tray is in the arc groove, the limit spring 327 can squeeze the block 326 to move toward the outside of the limit rod 325, and the block 326 clamps the limit rod 325 in the arc groove, so that the arc groove, the block 326, and the limit rod 325 can provide a certain supporting force for the mounting plate 320, reducing or even avoiding the possibility of shaking of the mounting plate 320; at this time, the bottom of the battery tray is supported and limited by the support plate 10, and the block 326 and the limit rod 325 can enter the arc groove to limit the rotation of the mounting plate 320, so that the block 326, the limit rod 325 and the arc groove provide additional supporting force for the battery tray through the mounting plate 320.

[0053] In another embodiment provided by the present invention, the cooling mechanism 41 includes a water outlet pipe 410, a mounting sleeve 411 is provided at the end of the water outlet pipe 410, and the mounting sleeve 411 is sleeved on the tool handle. The middle part of the tool handle and the milling cutter is a cavity structure, and the cavity structure is connected to the water outlet pipe 410;

[0054] The specific implementation is as follows: the end of the water outlet pipe 410 away from the milling cutter is connected to an external water pump, so that the water pump can transport the coolant into the water outlet pipe 410, so that the water outlet pipe 410 transports the coolant into the mounting sleeve 411, so that the mounting sleeve 411 sprays the coolant on the shank of the milling cutter, so that the coolant cools the milling cutter during milling; further, the milling cutter and the shank can be made into a cavity structure, so that the cavity structure is connected to the water outlet pipe 410, so that the coolant can flow out directly from the middle of the milling cutter, so that the coolant can fully cool the milling cutter while washing away the waste chips generated during milling.

[0055] In another embodiment provided by the present invention, the end of the cooling air duct 42 close to the milling cutter is a tapered tube 420, and the tapered tube 420 is connected to the cooling air duct 42 via a ball joint;

[0056] The specific implementation is as follows: one end of the cooling air duct 42 away from the tapered tube 420 is connected to an external air pump, and the tapered tube 420 reduces the diameter of the air flow ejection and accelerates the flow rate of the air flow. In this way, when the milling cutter is milling, the air pump transports air flow into the cooling air duct 42, so that the air flow passes through the cooling air duct 42 and is sprayed from the tapered tube 420 toward the milling cutter, so that the high-speed air flow cools the milling cutter while blowing away the waste chips generated by milling, thereby preventing the waste chips from affecting the milling effect of the milling cutter.

[0057] Working principle: Place the battery tray on the support plate 10. When clamping the battery tray, the dual-output motor 321 drives the two second threaded rods 322 installed at its two output ends to rotate synchronously. Since the screw directions of the two second threaded rods 322 are set in opposite directions, the two second threaded rods 322 respectively drive the connecting blocks 323 set thereon to move in opposite directions, that is, the two connecting blocks 323 move away from each other. At this time, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 and the threaded block 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position height of the support plate 10 so that the support plate 10 can lift the battery tray to The clamping claws 33 are at the same height as the clamping claws 33 so that the battery tray can enter between the clamping claws 33. After the battery tray enters between the clamping claws 33, the dual-output motor 321 drives the two second threaded rods 322 installed at its two output ends to rotate synchronously in opposite directions, so that the two second threaded rods 322 respectively drive the connecting blocks 323 provided thereon to move in relative directions, that is, the two threaded blocks 12 approach each other, so that the clamping claws 33 approach the corner of the battery tray. At this time, the clamping claws 33 are driven by the hydraulic telescopic rods 324 to move in the direction close to the battery tray, so that the clamping claws 33 approach and fit the edge surface of the battery tray, so that the clamping claws 33 clamp the battery tray The cam 330 is locked and locked in place, and the cam 331 is locked, so the cam 332 is locked and locked. The inclined surface of the wedge block 332 squeezes the L-shaped plate 331, causing the L-shaped plate 331 to slide along the moving block 330, thereby causing the right angle of the L-shaped plate 331 to move toward and fit the corner of the battery tray, so that the wedge block 332 and the L-shaped plate 331 clamp and fix the battery tray; and when the hydraulic telescopic rod 324 drives the moving block 330 to fit the edge of the battery tray, the movement and sliding of the L-shaped plate 331 reaches the maximum, so that the L-shaped plate 331 has enough movement distance so that the right angle of the L-shaped plate 331 can be sufficiently close to the corner of the battery tray, ensuring that the L-shaped plate 331 can provide sufficient squeezing force and sufficient fitting area to clamp and fix the battery tray;The cam 332 is pressed against the outer wall of the movable block 330, and the cam 333 is pressed against the inner wall of the movable block 330, so that the cam 333 is pressed against the inner wall of the movable block 330, and the cam 333 is pressed against the outer wall of the movable block 330, so that the cam 333 is pressed against the inner wall of the movable block 330, and the cam 333 is pressed against the inner ... outer wall of the movable block 330, so that the cam 333 is pressed against the outer wall of the movable block 330, and the cam 333 is pressed against the outer wall of the movable block 330, so that the cam 333 is pressed against the outer wall of the movable block 330, and the cam 333 is pressed against the outer wall of the movable block 330, so that the cam 333 is pressed against the outer wall of the movable block 330, and the cam 333 is pressed against the outer wall of the movable block

[0058] After the battery tray is clamped and fixed, the ∩-shaped frame 20 is driven to move by the slide rail 21, so that the ∩-shaped frame 20 drives the milling unit 22 to move, so that the milling unit 22 mills the battery tray; the end of the water outlet pipe 410 away from the milling cutter is connected to the external water pump, so that the water pump can transport the coolant into the water outlet pipe 410, so that the water outlet pipe 410 transports the coolant into the mounting sleeve 411, so that the mounting sleeve 411 sprays coolant on the shank of the milling cutter, so that the coolant cools the milling cutter during milling; further, the milling cutter and the shank can be made into a cavity structure, so that the cavity structure is connected to the water outlet pipe 410, so that the coolant can flow out directly from the middle of the milling cutter, so that the coolant can fully cool the milling cutter while The waste chips generated during milling can be washed away. At the same time, the cooling air duct 42 is connected to an external air pump at one end away from the tapered tube 420. The tapered tube 420 reduces the diameter of the airflow and speeds up the airflow rate. In this way, when the milling cutter is milling, the air pump delivers airflow into the cooling air duct 42, so that the airflow passes through the cooling air duct 42 and is sprayed from the tapered tube 420 toward the milling cutter, thereby allowing the high-speed airflow to cool the milling cutter while blowing away the waste chips generated during milling, thereby preventing the waste chips from affecting the milling effect of the milling cutter. When the battery tray is milled, in order to prevent the battery tray from being subjected to excessive force and being separated from the clamping mechanism 32 during the milling process, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 drives the two threaded blocks arranged thereon through threaded cooperation. 12 moves, thereby making the threaded block 12 drive the connecting rod 11 connected thereto to move, so that the connecting rod 11 adjusts the position height of the support plate 10, so that the support plate 10 can support and limit the lower end of the battery tray during the milling process according to the processing environment, thereby avoiding the situation where the clamp assembly 3 is insufficiently fixed to the battery tray due to excessive pressure when the milling unit 22 is milling or drilling, resulting in milling failure. Specifically, when the milling unit 22 mills a plane or drills a hole on the battery tray, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 drives the two threaded blocks 12 set thereon to approach each other, so that the threaded block 12 drives the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position of the support plate 10. The height is set so that the support plate 10 rises and sticks to the lower end of the battery tray, so that the support plate 10 supports and limits the battery tray during milling and drilling, and prevents the battery tray from being separated from the clamping mechanism 32 and falling due to excessive force; when the driving mechanism 34 drives the rotation adjustment through the clamping mechanism 32, the first motor 15 drives the first threaded rod 14 to rotate in the opposite direction, so that the first threaded rod 14 drives the two threaded blocks 12 provided thereon to move away from each other, thereby causing the threaded block 12 to drive the connecting rod 11 to rotate and move, so that the connecting rod 11 drives the support plate 10 to descend, so that the support plate 10 descends and moves away from the lower end of the battery tray, so that the support plate 10 makes room, which facilitates the rotation adjustment driven by the driving mechanism 34 through the clamping mechanism 32;

[0059] When the battery tray is rotated and adjusted, the first threaded rod 14 rotates in the opposite direction through the first motor 15, so that the first threaded rod 14 drives the two threaded blocks 12 arranged thereon to move away from each other, thereby causing the threaded blocks 12 to drive the connecting rod 11 to rotate and move, so that the connecting rod 11 drives the support plate 10 to descend, so that the support plate 10 descends and moves away from the lower end of the battery tray, so that the support plate 10 makes room. At this time, the first synchronous wheel 341 is driven to rotate by the driving motor 340, so that the first synchronous wheel 341 drives the second synchronous wheel 342 to rotate synchronously through the synchronous belt 343, thereby The second synchronous wheel 342 drives the clamping mechanism 32 to rotate through the rotating shaft 31, so that the clamping mechanism 32 drives the battery tray to rotate through the clamping claw 33, so that the driving mechanism 34 flips instead of manually flipping, and there is no need to perform the re-fixing step when the driving mechanism 34 drives the battery tray to flip, thereby shortening the milling processing time of the battery tray. After the battery tray is flipped, the first motor 15 drives the first threaded rod 14 to rotate, so that the first threaded rod 14 and the threaded block 12 drive the connecting rod 11 to rotate and move, so that the connecting rod 11 adjusts the position of the support plate 10 height, so that the support plate 10 rises again and sticks to the lower end of the battery tray, so that the support plate 10 supports and limits the battery tray during milling and drilling; in particular, when the milling position of the battery tray is not in a horizontal position, that is, the milling position of the battery tray does not coincide with the horizontal plane, the first synchronous wheel 341 is driven to rotate by the driving motor 340, so that the first synchronous wheel 341 drives the second synchronous wheel 342 to rotate through the synchronous belt 343, so that the second synchronous wheel 342 drives the clamping mechanism 32 to rotate through the rotating shaft 31, so that the clamping mechanism 32 drives the battery tray to rotate The battery tray is rotated to different angles so that the clamping mechanism 32 adjusts the position to be milled of the battery tray to a horizontal position, so that the milling unit 22 can mill the position to be milled of the battery tray without replacing the fixture, thereby improving the applicability of the equipment; and at this time, only the driving mechanism 34 is used to limit the rotation of the mounting plate 320. When the battery tray is in a horizontal state, the milling action is much more than the milling action when the battery tray is not in a horizontal position. Therefore, the driving mechanism 34 temporarily limits the mounting plate 320 to prevent the mounting plate 320 from rotating, ensuring that the milling of the battery tray can be carried out normally.In addition, the limit rods 325 are symmetrically arranged on one side of the mounting plate 320 close to the bracket 30. When the mounting plate 320 is in a horizontal or approximately horizontal state, that is, when the milling position of the battery tray is in a horizontal or approximately horizontal state, the first motor 15 drives the mounting plate 320 to rotate through the first synchronous wheel 341, the synchronous belt 343 and the second synchronous wheel 342. The mounting plate 320 drives the two limit rods 325 to rotate synchronously around the rotating shaft 31, and the two limit rods 325 rotate around the rotating shaft 31. The trajectory of the two limit rods 325 passes through the arc groove when rotating around the rotating shaft 31. When the clamping mechanism 32 drives the battery tray to rotate to the specified position, when the limit rod 325 is in the arc groove When the battery tray is in the correct position, the retaining spring 327 can squeeze the clamping block 326 to move outward from the retaining rod 325. The clamping block 326 can then lock the retaining rod 325 in the arc groove. This allows the arc groove, clamping block 326, and retaining rod 325 to provide a certain amount of support for the mounting plate 320, reducing or even preventing the mounting plate 320 from shaking. At this time, the support plate 10 supports and limits the bottom of the battery tray. At the same time, the clamping block 326 and retaining rod 325 can enter the arc groove to limit the rotation of the mounting plate 320. In this way, the clamping block 326, retaining rod 325, and the arc groove provide additional support for the battery tray through the mounting plate 320.
