[0002] A reciprocating high-frequency electric grinding machine, also known as an electric grinding machine, mainly uses electricity to drive a file to perform high-frequency reciprocating motion on the object to be ground to achieve the grinding effect.

[0003] With the rapid development of the new energy vehicle industry, as a core component of the power battery thermal management system, the manufacturing precision of the metal shell of the automotive battery cooler directly affects the overall heat dissipation performance and sealing reliability. During the welding and forming process, defects such as weld marks and spatter will inevitably occur on the surface of the metal shell. Traditional processes mostly use grinders for grinding. However, the grinding by grinders has problems such as uneven grinding depth and difficult control of surface flatness; when using an electric grinding machine for grinding, the thickness of the weld mark cannot be determined, and it is extremely easy to cause the wall thickness of the shell to be thinned due to excessive grinding, or residual weld marks to cause risks such as sealing failure. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a precision grinding device for metal shells of automotive battery coolers with high-frequency reciprocating grinding. When the weld mark is ground off, the elastic resistance terminals on both sides of the tool handle block the further descent of the tool handle. Then, the downward elastic force of the pressing spring on the file cutter is offset, so that the file cutter is in a force balance state on the surface of the metal shell of the automotive battery cooler. Therefore, even when the file cutter is in a reciprocating motion state, it will not cause wear to the surface of the metal shell of the automotive battery cooler. Thus, when using a file cutter with high-frequency reciprocating motion to grind the weld marks on the metal shell of the automotive battery cooler, it can avoid excessive grinding of the metal shell of the automotive battery cooler by the file cutter in the high-frequency state, and thus achieve the purpose of precise grinding. This solves the problems such as uneven grinding depth and difficult control of surface flatness in grinding by grinders; when using an electric grinding machine for grinding, the thickness of the weld mark cannot be determined, and it is extremely easy to cause the wall thickness of the shell to be thinned due to excessive grinding, or residual weld marks to cause risks such as sealing failure.

[0015] Compared with the prior art, the present invention provides a fine grinding device for the metal shell of an automotive battery cooler with high-frequency reciprocating grinding, and has the following beneficial effects: 1. The precision grinding device for the metal shell of the automotive battery cooler with high-frequency reciprocating grinding installs the vertical positioning and locking mechanism through the positioning grooves opened on the installation grooves, so that the carrier plate in the vertical positioning and locking mechanism drives the locking convex ring to move along the positioning grooves. When the carrier plate moves into the positioning grooves, the locking convex ring moves synchronously in the card slots. Until the locking convex ring contacts the rotating shaft on the detection flat plate, the locking convex ring fixes the rotating shaft in the vertical direction. When the detection flat plate rotates, the rotating shaft and the locking convex ring roll relative to each other, and the locking convex ring rotates on its own on the carrier plate, so that the detection flat plate is fixed in the vertical direction and can be fixed in the horizontal direction. When it is necessary to adjust the vertical position of the detection flat plate, under the action of the reset elastic piece, the carrier plate moves out of the positioning grooves and drives the locking convex ring to move together until the locking convex ring moves to the connection between the card slot and the positioning groove, and the card slot catches the locking convex ring to prevent the locking convex ring from moving out of the positioning groove. At this time, the locking convex ring is separated from the rotating shaft, and the rotating shaft is not stressed in the vertical direction and can move up and down freely, so as to realize the detection of the weld thickness on the upper surface of the metal shell of the automotive battery cooler by the scratch detection mechanism, and judge the grinding degree required by the filing mechanism according to the weld height of the metal shell of the automotive battery cooler.

[0016] 2. The precision grinding device for the metal shell of the automotive battery cooler with high-frequency reciprocating grinding limits the maximum range that the filing mechanism can descend by the height of the detection flat plate, that is, the maximum degree that the filing mechanism can grind the weld on the surface of the metal shell of the automotive battery cooler. Under the action of the downward pressure spring, the file knife receives a downward elastic force, so that the file knife passes through the detection flat plate and acts on the weld on the surface of the metal shell of the automotive battery cooler. Then, the file knife in the high-frequency reciprocating state grinds the weld on the surface of the metal shell of the automotive battery cooler. After the detection flat plate rotates back into the machine shell, the filing mechanism starts to operate. Under the action of the downward pressure spring, the tool handle drives the file knife to act on the weld on the surface of the metal shell of the automotive battery cooler. Under the movement of the file knife in the high-frequency reciprocating state, the weld of the metal shell of the automotive battery cooler is ground. When the installation side ears on both sides of the tool handle move downward from the inside of the notch and move until the convex rods at the bottom of the installation side ears contact the elastic resistance terminals on both sides of the detection flat plate, the elastic resistance terminals cancel the downward elastic force of the downward pressure spring, so that the file knife loses the acting force on the surface of the metal shell of the automotive battery cooler.

[0017] 3. For the precision grinding device of the metal shell of the automotive battery cooler with high-frequency reciprocating grinding, when the welding mark is ground off, the elastic resistance terminals on both sides of the tool shank block the further descent of the tool shank at this time. As a result, the downward elastic force of the pressing spring on the file grinding tool is offset, making the file grinding tool in a force balance state on the surface of the metal shell of the automotive battery cooler. Therefore, even when the file grinding tool is in a reciprocating motion state, it will not cause wear to the surface of the metal shell of the automotive battery cooler. Thus, when using the file grinding tool with high-frequency reciprocation to grind the welding mark on the metal shell of the automotive battery cooler, it is possible to avoid excessive grinding of the metal shell of the automotive battery cooler by the file grinding tool in the high-frequency state, and further achieve the purpose of precise grinding.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8 , a precision grinding device for the metal shell of an automotive battery cooler with high-frequency reciprocating grinding, including a material taking table 1. One end of the material taking table 1 is provided with a material placing table 2. Above the material placing table 2 is provided a filing mechanism 3. The filing mechanism 3 includes a filing knife 31 and a knife handle 32. The outside of the filing mechanism 3 is sleeved with a machine shell 4. The knife handle 32 is installed inside the machine shell 4. Above the knife handle 32 is provided a grinding mark detection mechanism 5. The grinding mark detection mechanism 5 includes a detection flat plate 51, a downward pressing spring 52 and an elastic resistance terminal 53. The downward pressing spring 52 is arranged between the top of the knife handle 32 and the machine shell 4. The detection flat plate 51 is located at the bottom of the knife handle 32. The elastic resistance terminal 53 is located at positions on both sides of the detection flat plate 51 close to the knife handle 32. One side of the detection flat plate 51 is rotatably connected to the machine shell 4. On one side of the machine shell 4 is provided a vertical positioning and locking mechanism 6. The vertical positioning and locking mechanism 6 includes a locking convex ring 61. The locking convex ring 61 is rotatably connected to the machine shell 4. A clamping groove 41 is arranged between the locking convex ring 61 and the machine shell 4. When the detection flat plate 51 moves above the grinding mark, the locking convex ring 61 moves into the machine shell 4 through the clamping groove 41. The locking convex ring 61 contacts the detection flat plate 51. The detection flat plate 51 is horizontally and rotatably connected to the locking convex ring 61.

[0022] In use, the metal shell of the automotive battery cooler is placed on the feeding table 2 through the material taking table 1 and waits to have the welding marks ground off. Then, the grinding mark detection mechanism 5 is used to detect the thickness of the welding marks on the upper surface of the metal shell of the automotive battery cooler. According to the height of the welding marks on the metal shell of the automotive battery cooler, the grinding degree required by the filing mechanism 3 is determined. First, the detection plate 51 in the grinding mark detection mechanism 5 rotates out from inside the casing 4 and is placed above the welding marks on the metal shell of the automotive battery cooler. Then, the detection plate 51 is placed on the welding marks on the surface of the metal shell of the automotive battery cooler. At this time, the tool handle 32 in the filing mechanism 3 is located above the detection plate 51. Further, the vertical positioning and locking mechanism 6 is used to vertically fix the detection plate 51. The locking collar 61 in the vertical positioning and locking mechanism 6 moves towards the card slot 41 and abuts against the detection plate 51, so that the detection plate 51 cannot move in the vertical direction. Then, the detection plate 51 is rotated back into the casing 4. At this time, the height at which the detection plate 51 is located limits the maximum range that the filing mechanism 3 can descend, that is, the maximum degree to which the filing mechanism 3 can grind the welding marks on the surface of the metal shell of the automotive battery cooler. Under the action of the downward pressure spring 52, the filing knife 31 receives a downward elastic force, so that the filing knife 31 passes through the detection plate 51 and acts on the welding marks on the surface of the metal shell of the automotive battery cooler. Furthermore, the filing knife 31 in the high-frequency reciprocating state grinds the welding marks on the surface of the metal shell of the automotive battery cooler. When the welding marks are ground off, at this time, the elastic force blocking terminals 53 on both sides of the tool handle 32 block the tool handle 32 from continuing to descend. Furthermore, the downward elastic force of the downward pressure spring 52 on the filing knife 31 is offset, so that the filing knife 31 is in a force balance state on the surface of the metal shell of the automotive battery cooler. Furthermore, even when the filing knife 31 is in a reciprocating motion state, it will not cause wear to the surface of the metal shell of the automotive battery cooler. Furthermore, when using the filing knife 31 in high-frequency reciprocation to grind the welding marks on the metal shell of the automotive battery cooler, it is avoided that the filing knife 31 in the high-frequency state causes excessive grinding to the metal shell of the automotive battery cooler, thereby achieving the purpose of precise grinding.

[0023] Further, a vertical driving mechanism 7 is provided on the back of the casing 4. The vertical driving mechanism 7 includes an electric driving rod 71 and a calibration pointer 72. The calibration pointer 72 is located at the bottom of the casing 4 and points to the material placing table 2. The electric driving rod 71 is located at the bottom of the casing 4, and the bottom of the electric driving rod 71 is fixed to one side of the material placing table 2. The position of the casing 4 is adjusted by the vertical driving mechanism 7. The electric driving rod 71 drives the casing 4 to move up and down, so that the calibration pointer 72 is flush with the surface of the metal shell of the automotive battery cooler. Initially, the initial position of the detection plate 51 is flush with the calibration pointer 72. At the beginning, the electric driving rod 71 drives the casing 4 to rise, and then the detection plate 51 rotates out from the inside of the casing 4 and is placed above the weld mark of the metal shell of the automotive battery cooler. At this time, the electric driving rod 71 drives the casing 4 to descend, so that the detection plate 51 descends onto the weld mark of the metal shell of the automotive battery cooler. As the electric driving rod 71 continues to descend, the detection plate 51 rises inside the casing 4 and pushes the grinding mechanism 3 above it to rise and further compress the pressing spring 52 until the calibration pointer 72 on the casing 4 is flush with the surface of the metal shell of the automotive battery cooler, and then the electric driving rod 71 is fixed. At this time, the casing 4 is in a fixed state. Then, the detection plate 51 is rotated back into the casing 4, and the weld mark on the surface of the metal shell of the automotive battery cooler is ground by the grinding mechanism 3.

[0024] Further, a guiding installation groove 42 is provided inside the casing 4. The tool handle 32 is installed inside the guiding installation groove 42. Installation side ears 321 are provided above the guiding installation groove 42 on both sides of the tool handle 32. A guiding shaft 421 is provided above the guiding installation groove 42. The installation side ears 321 are slidably connected to the guiding shaft 421. Through the installation of the tool handle 32 in the guiding installation groove 42, under the guiding action of the guiding shaft 421, the installation side ears 321 on both sides of the tool handle 32 enable the tool handle 32 to slide along the direction of the guiding installation groove 42.

[0025] Further, the pressing spring 52 is sleeved on the guiding shaft 421. Two ends of the pressing spring 52 are respectively connected to the inner cavity of the machine housing 4 and the mounting side ear 321. A convex rod 322 is arranged at the bottom of the mounting side ear 321. A notch 422 is formed in the side wall of the guiding installation groove 42. The convex rod 322 is located inside the notch 422, and the convex rod 322 is arranged corresponding to the elastic force blocking terminal 53. The pressing spring 52 sleeved on the guiding shaft 421 is in a compressed state, applying a downward elastic force to the mounting side ear 321, so that the tool handle 32 receives a downward elastic force. After the detection flat plate 51 rotates back into the machine housing 4, the filing mechanism 3 starts to operate. Under the action of the pressing spring 52, the tool handle 32 drives the filing cutter 31 to act on the weld mark on the surface of the metal shell of the automotive battery cooler. Under the movement of the filing cutter 31 in a high-frequency reciprocating state, the weld mark on the metal shell of the automotive battery cooler is ground. When the mounting side ears 321 on both sides of the tool handle 32 move downward from inside the notch 422 and the convex rod 322 at the bottom of the mounting side ear 321 contacts the elastic force blocking terminals 53 on both sides of the detection flat plate 51, the elastic force blocking terminals 53 cancel out the downward elastic force of the pressing spring 52, so that the filing cutter 31 loses the acting force on the surface of the metal shell of the automotive battery cooler.

[0026] Further, a rotating shaft 511 is arranged on one side of the detection flat plate 51. A detection installation groove 43 is arranged inside the machine housing 4. The rotating shaft 511 is rotationally connected to the detection installation groove 43 and is also slidably connected to the detection installation groove 43. A filing channel 512 is formed on the other side of the detection flat plate 51. The elastic force blocking terminals 53 are located on both sides of the filing channel 512. The rotating shaft 511 on one side of the detection flat plate 51 drives the detection flat plate 51 to rotate in the detection installation groove 43 inside the machine housing 4, so that the detection flat plate 51 can rotate out of and into the machine housing 4. After the detection flat plate 51 finishes detecting the weld mark on the metal shell of the automotive battery cooler, the detection flat plate 51 rotates into the machine housing 4 by the rotating shaft 511. At this time, the filing channel 512 on the detection flat plate 51 coincides with the guiding installation groove 42 on the machine housing 4, so that the filing mechanism 3 can move downward along the guiding installation groove 42 and the filing channel 512.

[0027] Further, a positioning groove 431 is formed in the detection installation groove 43. The positioning groove 431 extends to the clamping groove 41, and the positioning groove 431 is communicated with the clamping groove 41. The vertical positioning and locking mechanism 6 is arranged in the positioning groove 431. The vertical positioning and locking mechanism 6 further includes a carrier plate 62 and a reset elastic piece 63. The carrier plate 62 is slidably arranged inside the positioning groove 431. The locking convex ring 61 is rotatably arranged on the carrier plate 62. The reset elastic piece 63 is located between the positioning groove 431 and the carrier plate 62. Through the installation of the vertical positioning and locking mechanism 6 in the positioning groove 431 formed in the detection installation groove 43, the carrier plate 62 in the vertical positioning and locking mechanism 6 can drive the locking convex ring 61 to move along the positioning groove 431. When the carrier plate 62 moves into the positioning groove 431, the locking convex ring 61 moves synchronously in the clamping groove 41. Until the locking convex ring 61 contacts the rotating shaft 511 on the detection flat plate 51, the locking convex ring 61 fixes the rotating shaft 511 in the vertical direction. When the detection flat plate 51 rotates, the rotating shaft 511 and the locking convex ring 61 roll relative to each other, and the locking convex ring 61 rotates on the carrier plate 62, so that the detection flat plate 51 is fixed in the vertical direction and can be fixed in the horizontal direction. When it is necessary to adjust the vertical position of the detection flat plate 51, under the action of the reset elastic piece 63, the carrier plate 62 moves out of the positioning groove 431 and drives the locking convex ring 61 to move together until the locking convex ring 61 moves to the connection part of the clamping groove 41 and the positioning groove 431, and the clamping groove 41 clamps the locking convex ring 61 to prevent the locking convex ring 61 from moving out of the positioning groove 431. At this time, the locking convex ring 61 is separated from the rotating shaft 511, and the rotating shaft 511 is not stressed in the vertical direction and can move up and down freely.

[0028] Further, one end of the carrier plate 62 extends outside the positioning groove 431. A wedge-shaped clamping block 432 is arranged outside the positioning groove 431. A clamping opening 621 is arranged on the carrier plate 62. The wedge-shaped clamping block 432 corresponds to the clamping opening 621. Through the clamping opening 621 arranged at one end of the carrier plate 62, cooperating with the wedge-shaped clamping block 432 arranged outside the positioning groove 431, when the carrier plate 62 moves into the positioning groove 431, the clamping opening 621 moves to the bottom of the wedge-shaped clamping block 432, and then the wedge-shaped clamping block 432 is clamped inside the clamping opening 621, so that the carrier plate 62 is relatively fixed to the positioning groove 431, and then the locking convex ring 61 on the other side of the carrier plate 62 is closely attached to the rotating shaft 511.

[0029] Further, the material taking table 1 includes a material taking mechanical gripper 11, a conveying platform 12, and an output platform 13. The conveying platform 12 is located on one side of the material placing table 2, and the output platform 13 is located on the other side of the material placing table 2. The material taking mechanical grippers 11 are respectively arranged on both sides of the material placing table 2. The metal shell of the automotive battery cooler to be ground conveyed on the conveying platform 12 is placed on the material placing table 2 by the material taking mechanical gripper 11 in the material taking table 1. After the metal shell of the automotive battery cooler is ground on the material placing table 2, the ground metal shell of the automotive battery cooler is taken off by the material taking mechanical gripper 11 on the other side and placed on the output platform 13 for removal.

[0030] Further, the material placing table 2 is located between the conveying platform 12 and the output platform 13. A stepping motor 21 is arranged at the bottom of the material placing table 2, and the stepping motor 21 is used to drive the material placing table 2 to rotate step by step. After the metal shell of the automotive battery cooler is placed on the material placing table 2 by the material taking mechanical gripper 11, the stepping motor 21 at the bottom of the material placing table 2 rotates step by step, driving the metal shell of the automotive battery cooler on the material placing table 2 to step one unit, that is, to be located below the filing mechanism 3. At the same time, the material taking mechanical gripper 11 at the conveying platform 12 grabs another metal shell of the automotive battery cooler to be ground and places it on the material placing table 2. After the metal shell of the automotive battery cooler is ground, the stepping motor 21 steps one unit again, moving the metal shell of the automotive battery cooler to below the material taking mechanical gripper 11 at the output platform 13, and another metal shell of the automotive battery cooler to be ground rotates to below the filing mechanism 3. By operating in this way, the feeding, grinding, and discharging of the metal shell of the automotive battery cooler are completed.

[0031] Further, a processing frame 8 is arranged at the bottom of the material placing table 2. The vertical driving mechanism 7 is located at the upper back side of the processing frame 8, and the conveying platform 12 and the output platform 13 are respectively located on both sides of the front of the processing frame 8.
