Description

Technical Field

[0001] The present application relates to the technical field of polishing equipment, and in particular to a battery box shell machining and polishing device. Background Art

[0002] With the development of science and technology in recent years, the use of new energy electric vehicles has become increasingly widespread. For new energy electric vehicles, their most core component is their battery. The battery of a new energy electric vehicle is installed under the vehicle under the protection of the battery box. In order to ensure the battery can operate stably during the use of new energy electric vehicles, the quality of the battery box is required to be high.

[0003] Existing battery boxes are typically welded together from alloy materials (such as aluminum alloy) to provide a high level of structural strength. However, these welds leave visible weld marks at the joints between the alloy materials. These marks can create surface unevenness, affecting the aesthetics of the battery box. This is especially true for exposed areas after installation, which can negatively impact the overall aesthetics of new energy electric vehicles.

[0004] To address this issue, workers typically use polishing equipment such as angle grinders to polish the battery box after welding to remove weld marks and create a smooth surface. However, polishing with existing polishing equipment (such as angle grinders) is difficult and can easily lead to over-polishing, resulting in surface damage. This not only affects the appearance of the battery box, but may also affect the overall structural strength of the battery box. Summary of the Invention

[0005] In order to improve the problem that existing polishing equipment is difficult to operate and easily affects the polishing effect, the present application provides a battery box shell machining and polishing device.

[0006] This application provides a battery box shell machining and polishing device, which adopts the following technical solutions:

[0007] A battery box shell machining and polishing device includes a polishing machine, which includes a machine body, a first driving member, a polishing member, a cover body and a guide assembly. The first driving member and the cover body are fixedly arranged on the machine body. The cover body has a protective groove on the side facing away from the machine body. The polishing member is rotatably connected to the machine body and is located in the protective groove. The first driving member drives the polishing member to rotate. The guide assembly includes two movable members, which are respectively located on both sides of the polishing member. The movable member is slidably connected to the cover body. The sliding trajectory of the movable member is an arc. When the movable member slides to abut against the cover body, the end face of the movable member facing away from the machine body is parallel to the end face of the polishing member facing away from the machine body; the guide assembly also includes two adjusting members, which control the sliding of the movable member and can fix the position of the movable member.

[0008] By adopting the above technical solution, when using a polishing machine to polish the welding marks on the surface of the battery box, the control adjustment part makes the two movable parts slide to the two end faces adjacent to the position to be polished and abut against each other. At this time, the polishing part is flush with one of the end faces. Under the premise that the two movable parts remain abutted against the corresponding end faces, the machine body is moved to make the polishing part polish the welding marks. The polished end face of the welding mark can be flush with one of the end faces, which reduces the difficulty of polishing the battery box surface and improves the polishing effect. At the same time, the cover can prevent some particles generated during the polishing process from flying out, reduce dust, and create a better working environment.

[0009] Optionally, the body includes a main handle and a secondary handle, the length direction of the main handle is parallel to the axis of the sliding track of the movable part, the length directions of the main handle and the secondary handle are both perpendicular to the rotation axis of the polishing part, and the length direction of the main handle is perpendicular to the length direction of the secondary handle.

[0010] By adopting the above technical solution, when using the polishing machine, the dominant hand holds the main handle and the auxiliary hand holds the secondary handle, which can facilitate the staff to control the machine body to move along a certain trajectory and at a certain speed, so that the machine body can remain stable during the movement, reducing the amplitude of the machine body shaking caused by the collision between the polishing parts and the welding marks during the polishing process, thereby reducing the difficulty of polishing and improving the polishing quality of the battery box.

[0011] Optionally, an extension portion is extended from one end of the movable member away from the main handle bar in a direction parallel to the length direction of the main handle bar.

[0012] By adopting the above technical solution, after operating the adjustment part to control the sliding of the movable part, the extension part is respectively abutted against the end faces of the battery box on both sides of the welding mark to be polished, and the two extension parts are used to check whether the sliding rotation of the movable part is in place; at the same time, when starting the polishing process, the extension part is first abutted against the end face of the battery box, and the moving direction of the polishing machine can be determined in advance according to the shape of the battery box, thereby making the polishing of the welding machine mark more accurate and reducing the probability of excessive polishing and damage to the end face of the battery box due to operational errors at the beginning of polishing.

[0013] Optionally, the guide assembly further includes a plurality of rolling members, which are arranged at an end of the movable member facing away from the body. When the polishing member is flush with an end face of the battery box, the rolling members all abut against the surface of the battery box.

[0014] By adopting the above technical solution, the two movable parts are respectively against the two end faces of the battery box through several rolling parts. When the polishing machine moves, the rolling parts roll, reducing the friction between the movable parts and the battery box, making it easier for the staff to control the movement of the polishing machine; and, the staff can control the movement of the polishing machine while keeping the several rolling parts against the end faces of the battery box, which can make the surface of the polished welding marks smoother and flatter.

[0015] Optionally, the polishing machine further comprises two cooling components, wherein the cooling component comprises a cooling pad capable of storing water, the cooling pad is arranged on the movable part, and the cooling pad is provided with a plurality of clearance openings adapted to the rolling part.

[0016] By adopting the above technical solution, when the polishing machine polishes the welding trace, the cooling pad containing water inside is in contact with the end faces of the battery box on both sides of the welding trace and is close to the welding trace. When the polishing part rotates to polish the welding trace, the temperature of the welding trace and its surroundings will increase. High temperature can easily cause metal fatigue and is inconvenient for staff to touch. At this time, the cooling pad containing water inside can have a cooling effect on the area around the welding trace and suppress its temperature increase. In addition, the dust particles generated when the welding trace is polished will splash outward onto the cooling pad and can adhere to the cooling pad, thereby further reducing dust.

[0017] Optionally, the cooling component further includes a water storage part storing water therein and a plurality of seepage pipes, the water storage part is arranged on the movable part, one end of the seepage pipe is communicated with the interior of the water storage part, and the other end of the seepage pipe leads to the cooling pad.

[0018] By adopting the above technical solution, after the water contained in the cooling pad evaporates and has a cooling effect on the area around the welding marks on the battery box, the water storage component can replenish the water inside itself to the cooling pad through a number of seepage pipes, so that the cooling pad can maintain an internal water-containing state for a certain period of time, thereby enabling it to continue to play a cooling role during the polishing process and extend the working time of the cooling component.

[0019] Optionally, it also includes a storage seat and several positioning components. The storage seat is arranged on the workbench, and the several positioning components are all arranged at the edge of the storage seat. The several positioning components can fix the battery box on the storage seat.

[0020] By adopting the above technical solution, after the battery box is placed on the storage seat, several positioning components are used to position the battery box on the storage seat, so that the battery box can remain in a fixed position during the polishing process, making it convenient for staff to use a polishing machine to polish the battery box, and reducing the impact of the movement and vibration of the battery box during the polishing process on its final polishing quality.

[0021] Optionally, a second driving member is further included, wherein the second driving member is arranged on the workbench, the storage seat is rotatably connected to the workbench, and the second driving member drives the storage seat to rotate.

[0022] By adopting the above technical solution, after the battery box is placed on the storage seat and fixed in position by several positioning components, the staff uses a polishing machine to polish one side of the battery box. When the polishing of one side of the battery box is completed, the second driving member is controlled to drive the storage seat to rotate, and the staff can polish the other side of the battery box, making the process of polishing the battery box surface more convenient.

[0023] Optionally, an auxiliary mechanism is also included, which includes a frame, a guide frame and a movable assembly. The frame is slidably connected to the workbench in the horizontal direction, the guide frame is slidably connected to the frame in the vertical direction, the movable assembly is slidably connected to the guide frame along the length direction of the guide frame, and the polishing machine is detachably connected to the movable assembly.

[0024] By adopting the above technical solution, after the polishing machine is connected and installed with the moving component, the control frame is controlled to slide to a position close to the side of the battery box to be polished, and then the guide frame is controlled to slide in the direction close to the battery box until the guide frame and the top of the battery box are in contact with each other, and then the adjustment part is operated to control the sliding of the movable part so that the two movable parts are respectively in contact with the two end faces of the battery box. When the mobile polishing machine is subsequently used to polish the battery box, it is only necessary to control the moving component to slide along the length direction of the guide frame, which can further reduce the difficulty of using the polishing machine and further facilitate the staff to polish the welding marks of the straight track.

[0025] In summary, this application has at least one of the following beneficial effects:

[0026] 1. During the polishing process, the polishing machine can move with the battery box end faces on both sides of the welding mark to be polished as the guide through two movable parts, which can reduce the difficulty of polishing the battery box surface and improve the polishing effect of the polishing machine;

[0027] 2. The polishing machine can adapt to the angles between different adjacent end faces of the battery box, so that it can polish the welding marks between different adjacent end faces of the battery box, increasing the scope of application of the polishing machine and making it easy to operate;

[0028] 3. During the polishing process of the battery box, the cooling component can continuously cool the area around the polished welding marks, reducing the probability of metal fatigue in the battery box due to high temperature, which ultimately affects the structural strength of the battery box, while also preventing workers from touching the battery box.

[0029] 4. The staff can polish the entire surface of the battery box by controlling the second driving member to rotate the storage seat on one side of the workbench. The auxiliary components can make the polishing process more labor-saving, further reduce the difficulty of the polishing operation, and at the same time reduce the workload of the staff.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The embodiment of the present application discloses a battery box shell machining and polishing device.

[0039] Reference Figure 1 The polishing device includes a polishing machine 1 and a workbench 2. After the battery box 3 is inverted on the workbench 2 with the opening facing downward, the staff can use the polishing machine 1 to polish the welding marks on the surface of the battery box 3.

[0040] Reference Figure 1 and Figure 2 The polishing device also includes a storage seat 4 for positioning the battery box 3, a second drive member 5, and several positioning components 6. The storage seat 4 is centrally mounted on the top of the workbench 2 and is rotatably connected to the workbench 2, with the rotation axis of the storage seat 4 being vertical. The second drive member 5 is mounted inside the workbench 2, is fixedly connected to the storage seat 4, and is capable of driving the storage seat 4 to rotate. In this embodiment, the second drive member 5 is preferably a stepping motor. The second drive member 5 can drive the storage seat 4 to rotate a certain angle each time, and the angle of rotation of the storage seat 4 driven by the second drive member 5 each time is adjustable.

[0041] Several positioning assemblies 6 are fixedly mounted on the storage base 4. Preferably, four positioning assemblies 6 are mounted on the storage base 4, and the four positioning assemblies 6 are located at four positions on the edge of the storage base 4. After the battery box 3 is placed on the storage base 4, the four positioning assemblies 6 are located on different sides of the battery box 3. The positioning assemblies 6 can be controlled to clamp the battery box 3 in place, thereby fixing the battery box 3 in place on the storage base 4.

[0042] The positioning assembly 6 includes a clamping member 61 and a holding member 62. Each of the four edges of the storage seat 4 has an upwardly protruding mounting seat 41 for mounting the positioning assembly 6. The holding member 62 is horizontally slidably connected to the mounting seat 41 and is threadedly connected to the mounting seat 41. After the end of the clamping member 61 proximate to the battery box 3 abuts against the battery box 3, the end of the holding member 62 proximate to the battery box 3 abuts against the clamping member 61. As a result, the four positioning assemblies 6 simultaneously apply force to the battery box 3, thereby clamping and positioning the battery box 3 on the storage seat 4. In other embodiments, the positioning assembly 6 can also be pressed and positioned on the storage seat 4 by applying vertical downward pressure on the top of the battery box 3.

[0043] The workbench 2 is provided with a chip collection trough 21. The path of the chip collection trough 21 surrounds the placement seat and the chip collection trough 21 opens vertically upward on the workbench 2. A cover plate 22 is also fixedly mounted on the workbench 2 to cover the chip collection trough 21. The cover plate 22 has a plurality of holes formed in it. Dust particles generated during the polishing process can pass through the holes and be collected in the chip collection trough 21.

[0044] The polishing device also includes a chip collection assembly 7, which includes a chip box 71 and a fan 72. The chip box 71 is fixed to one side of the workbench 2, and the interior of the chip box 71 is connected to the chip chute 21 via a pipe. The fan 72 is fixedly mounted on the chip box 71 and is capable of driving dust particles formed during the polishing process and collected in the chip chute 21 into the interior of the chip box 71. In this embodiment, the fan 72 is preferably a blower 72.

[0045] Reference Figure 3 and Figure 4 The polishing machine 1 includes a body 11, a first driving member 12, a polishing member 13, and a cover 14. The body 11 includes a main body 111. The first driving member 12 is fixedly mounted inside the main body 111. The cover 14 is fixedly mounted on one side of the main body 111. A protective groove 141 is formed at the end of the cover 14 facing away from the main body 111. The polishing member 13 is located in the protective groove 141. The polishing member 13 is rotatably connected to the main body 111, and the first driving member 12 can drive the polishing member 13 to rotate. In this embodiment, the first driving member 12 is preferably a stepping motor, and the polishing member 13 is preferably a disc-shaped structure with a rough surface on one end surface (i.e., the polishing surface).

[0046] The machine body 11 also includes a main handle 112 and a secondary handle 113. The radial dimension of the main handle 112 is larger than that of the secondary handle 113. The length direction of the main handle 112 and the length direction of the secondary handle 113 are located in the same plane, and the plane is perpendicular to the rotation axis of the polishing member 13. The length direction of the main handle 112 and the length direction of the secondary handle 113 are perpendicular. In this embodiment, the main handle 112 is for the user to hold with the dominant hand, and the secondary handle 113 is for the user to hold with the auxiliary hand. The polishing machine 1 shown in the drawings is a right-handed model. In fact, the polishing machine 1 also has a left-handed model, and the user can freely choose the model to use according to their own situation. In this embodiment, the switch for controlling the opening and closing of the first drive member 12 is preferably installed on the main handle 112.

[0047] The polishing machine 1 also includes a guide assembly 15, which includes two movable members 151. The movable members 151 include a sliding portion 152 and an abutting portion 153. Two sliding grooves 142 are provided inside the cover body 14, which are compatible with the sliding portions 152. The movable members 151 are slidably connected to the cover body 14 via the sliding portions 152. The sliding trajectory of the movable members 151 is a circular arc trajectory, and the axis of the sliding trajectory of the movable members 151 is parallel to the length of the main handle 112. The sliding of the movable members 151 is limited. When the movable members 151 slide toward the cover body 14 to the extreme position, the abutting portion 153 abuts against the cover body 14. When both movable members 151 slide toward the extreme position away from the cover body 14, the abutting portions 153 of the two movable members 151 abut against each other.

[0048] The polishing machine 1 also includes two adjustment members 16 for controlling the sliding movement of the movable member 151. The two adjustment members 16 are respectively mounted at both ends of the housing 14. The adjustment members 16 are rotatably connected to the housing 14, and the rotation axis of the adjustment members 16 is parallel to the length of the main handle 112. The adjustment member 16 has a gear structure at one end located inside the housing 14, and the sliding portion 152 has a rack structure on the side near the adjustment member 16. The adjustment member 16 and the sliding portion 152 are meshed with the gear structure and the rack structure for transmission. Rotation of the adjustment member 16 drives the sliding portion 152 to move along the sliding groove 142, thereby sliding the movable member 151. In other embodiments, the adjustment member 16 can also be slidably connected to the housing 14, and the sliding movement of the movable member 151 is achieved by controlling the sliding movement of the adjustment member 16.

[0049] Reference Figure 4 and Figure 5The end of the abutting portion 153 away from the sliding portion 152 has two aligning flat surfaces 1531 and an intermediate surface 1532. The intermediate surface 1532 is located between the two aligning flat surfaces 1531, and the ends of the intermediate surface 1532 are respectively connected to the two aligning flat surfaces 1531. When the movable member 151 slides to the limit position toward the cover 14, the aligning flat surfaces 1531 on the two abutting portions 153 away from the polishing member 13 are located in the same plane, and the plane is parallel to the polishing surface of the polishing member 13. When one movable member 151 slides to the limit position toward the cover 14, the other movable member 151 slides away from the cover 14. During the process, the two aligning flat surfaces 1531 on the abutting portion 153 farther from the cover 14 can be perpendicular to the aligning flat surface 1531 on the abutting portion 153 closer to the cover 14, away from the polishing machine 1.

[0050] The guide assembly 15 further includes a plurality of rolling elements 154, each of which is rollingly mounted on the middle surface 1532 of the abutment portion 153. The rolling elements 154 are evenly spaced along the length of the middle surface 1532. The abutment portion 153 abuts against the end surface of the battery case 3 via the rolling elements 154. When both movable members 151 slide toward the cover 14 to their limit positions, the ends of the rolling elements 154 facing away from the cover 14 lie in the same plane, and this plane coincides with the polishing surface of the polishing element 13. In this embodiment, the rolling elements 154 are preferably ball bearings. When the ball bearings abut against the end surface of the battery case 3, the polishing machine 1 is controlled to move, and the ball bearings roll under the friction between the ball bearings and the end surface of the battery case 3.

[0051] The polishing machine 1 also includes a cooling assembly 17, which includes a cooling pad 171 capable of storing and discharging water, a water storage member 172 for storing water, and a plurality of seepage pipes 173. The water storage member 172 is fixedly mounted inside the abutment portion 153. The seepage pipes 173 are also fixedly mounted inside the abutment portion 153. One end of the seepage pipe 173 communicates with the interior of the water storage member 172, and the other end of the seepage pipe 173 passes through the leveling surface 1531. The plurality of seepage pipes 173 are evenly spaced along the length of the leveling surface 1531. The cooling pad 171 is provided with a plurality of clearance openings 1711 adapted to accommodate the rolling elements 154. The cooling pad 171 is fixedly mounted on the end surface of the abutment portion 153 away from the sliding portion 152, and covers both leveling surfaces 1531 and an intermediate surface 1532. The cooling pad 171 can deform after being squeezed, and the water stored inside the cooling pad 171 will flow out after deformation. The water seepage pipe 173 can continuously supply water to the cooling pad 171, so that the cooling pad 171 remains filled with water. When the rolling element 154 abuts against the end face of the battery box 3, the cooling pad 171 will also be in close contact with the end face of the battery box 3. In this embodiment, the cooling pad 171 is preferably a hard sponge. The hard sponge can continuously absorb water through the water seepage pipe 173 to replenish itself with water. At the same time, the amount of deformation after being squeezed is small. The cooling pad 171 is fixedly connected to the abutting portion 153 by bonding. The cooling pad 171 can be replaced after a period of use.

[0052] Reference Figure 3 and Figure 4 A water pipe 174 is also connected to one side of the water storage member 172. The water pipe 174 extends through the abutment portion 153 in a direction parallel to the length of the main handle 112. One end of the water pipe 174 communicates with the interior of the water storage member 172, while the other end communicates with the outside world. The end of the water pipe 174, which is remote from the water storage member 172, is normally closed. When the water storage member 172 is insufficient, the end of the water pipe 174, which is remote from the water storage member 172, can be opened to facilitate staff to add water to the water storage member 172.

[0053] An extension portion 1533 extends outward from the end of the abutment portion 153 away from the main handle 112 in a direction parallel to the length of the handle. When the end face of the extension portion 1533 away from the main body 111 abuts against the end face of the battery box 3, the multiple rolling elements 154 on the same abutment portion 153 abut against the end face of the battery box 3. When using the polishing machine 1, the two extension portions 1533 are first abutted against the end faces on both sides of the weld mark to be polished on the battery box 3, and then the polishing machine 1 is controlled to move to polish the weld mark. The extension portion 1533 can not only verify whether the adjustment member 16 is accurately adjusting the sliding position of the movable member 151, but also serve as a pre-contact guide, facilitating the polishing of the weld mark by the rotating polishing member 13.

[0054] Reference Figure 1 The polishing device also includes an auxiliary mechanism 8, which is used to assist the polishing machine 1 in polishing horizontal and long-distance welding tracks. The auxiliary mechanism 8 includes a frame 81, a guide frame 82, and a moving assembly 83. Bosses 23 extend outward from the two length sides of the workbench 2. The bottoms of both ends of the frame 81 are slidably connected to the bosses 23 in a direction parallel to the length direction of the workbench 2. A third driving member 84 for driving the frame 81 to slide is installed on the workbench 2. In this embodiment, the third driving member 84 preferably drives the frame 81 to slide in a screw drive manner, and the third driving member 84 is preferably a stepping motor.

[0055] Both ends of the guide frame 82 are connected to the frame body 81. The length direction of the guide frame 82 is parallel to the wide width direction of the workbench 2. The guide frame 82 and the frame body 81 are slidably connected in the vertical direction. A fourth driving member 85 for driving the guide frame 82 to slide is fixedly mounted on the frame body 81. In this embodiment, the fourth driving member 85 preferably also drives the guide frame 82 to slide in a screw drive manner, and the fourth driving member 85 is also preferably a stepping motor.

[0056] Reference Figure 3 and Figure 6 The moving assembly 83 includes a moving seat 831 and a rotating seat 832. The moving seat 831 is mounted on the guide frame 82 and is slidably connected to the guide frame 82 along the length of the guide frame 82. The rotating seat 832 is sleeved on the moving seat 831 and is rotatably connected to the moving seat 831. The rotation axis of the rotating seat 832 coincides with the center line of the moving seat 831. There is a large friction between the rotating seat 832 and the moving seat 831, and the operator needs to apply a certain amount of force to control the rotating seat 832 to rotate relative to the moving seat 831.

[0057] The polishing machine 1 is detachably connected to the rotating base 832. Plug-in blocks 114 extend outward from both sides of the main body 111 in a direction parallel to the length of the auxiliary handle 113. The rotating base 832 defines a slot 8321 for inserting the plug-in blocks 114. The end of the plug-in block 114 facing away from the main body 111 includes a snap-in portion 1141. The interior of the rotating base 832 defines a snap-in slot 8322 into which the snap-in portion 1141 snaps. The snap-in slot 8322 communicates with the end of the slot 8321 facing away from the main handle 113. When the plug-in block 114 is inserted into the slot 8321, the length of the main handle 112 is vertical. Once the plug-in block 114 is fully inserted into the slot 8321, rotating the polishing machine 1 causes the snap-in portion 1141 to snap into the slot 8322. At this point, the length of the main handle 112 is parallel to the sliding direction of the movable base 831.

[0058] In actual application, an operating table for controlling the second driving member 5 and the third driving member 84 is also installed around the workbench 2, and the operating table is omitted in the drawings.

[0059] The implementation principle of the battery box shell machining and polishing device in the embodiment of the present application is as follows:

[0060] First, the battery box 3 is placed upside down on the storage seat 4 and fixed on the storage seat 4 by a number of positioning parts. Then, the polishing machine 1 is held by hand, and the adjustment part 16 is operated to slide the two movable parts 151 so that the two abutting parts 153 are respectively abutted against the end faces on both sides of the welding mark to be polished on the battery box 3. Then, under the guidance of the guide component 15, the polishing machine 1 is moved with the end face of the battery box 3 as a reference, so that the rotating polishing part 13 polishes the welding mark; at the same time, during the polishing process, the cooling component 17 will continue to cool the area around the welding mark being polished, reduce the probability of metal fatigue caused by high temperature, and ensure the overall structural strength of the battery box 3; moreover, most of the dust particles generated during the polishing process can adhere to the cooling pad 171, reducing the dust phenomenon;

[0061] When polishing welding marks with a horizontal trajectory and a long length, they can be polished with the help of the auxiliary mechanism 8, which effectively reduces the time the staff spends holding the polishing machine 1 for a long time, reduces the staff's workload, and makes the polishing operation simpler and more convenient.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
