Description

Technical Field

[0001] This invention relates to the field of electric vehicle wheel hub processing, and in particular to a stamping forming equipment for electric vehicle wheel hubs. Background Technology

[0002] A wheel hub is a metal component mounted on the drive shaft of a vehicle. In everyday life, it is also called a wheel rim or steel rim. Wheel hubs are usually distinguished by their diameter, width, and molding method. Different specifications of wheel hubs correspond to different tire models. A wheel hub is a cylindrical metal component that supports the tire from the inside and is mounted on the axle. Wheel hubs come in many varieties depending on their diameter, width, molding method, and materials. Different wheel hubs are used according to the characteristics and needs of different vehicle models.

[0003] The publication number CN112427677A discloses an automotive aluminum alloy wheel hub drilling machine, which includes a middle clamping mechanism, a bottom frame mechanism, a clamping power mechanism, a vertical travel mechanism, and a chain drilling mechanism. The middle clamping mechanism clamps the automotive aluminum alloy wheel hub, and the bottom frame mechanism serves as the overall ground support. The clamping power mechanism and the middle clamping mechanism cooperate to make it move. The vertical travel mechanism drives the chain drilling mechanism to move up and down, so that the hole can be removed after drilling. The chain drilling mechanism consists of ten drill bits of different specifications, which are assembled inside the mechanism.

[0004] The wheel hub drilling machine described in the above technical solution has multiple drill bits in fixed positions, and can only drill holes in fixed positions on the wheel hub. The required drilling positions for different wheel hubs vary depending on their diameter. The drilling machine described in the above technical solution cannot adjust the position of the drill bits, and it cannot be used when it is necessary to drill holes in wheel hubs of different diameters. Summary of the Invention

[0005] In order to adjust the position of the drill bit on the drilling machine, this application provides a stamping forming device for electric vehicle wheel hubs.

[0006] The stamping forming equipment for electric vehicle wheel hubs provided in this application adopts the following technical solution:

[0007] A stamping forming device for electric vehicle wheel hubs includes a frame, a drilling mechanism, and a first driving component. The frame has a worktable with a clamping mechanism for mounting the wheel hub. The drilling mechanism drills holes in the wheel hub mounted on the worktable. The drilling mechanism includes multiple tool holders for clamping drill bits, an adjusting component, and a driving component. A stamping plate is slidably connected to the frame in a vertical direction. The multiple tool holders are slidably connected to the stamping plate in a direction perpendicular to the sliding direction of the stamping plate. The multiple tool holders are rotatably connected to the stamping plate in a vertical direction. The adjusting component simultaneously adjusts the position of the multiple tool holders on the stamping plate. The driving component drives the multiple tool holders to rotate simultaneously. The first driving component drives the sliding of the stamping plate.

[0008] By adopting the above technical solution, the wheel hub to be drilled is placed on the worktable, and the wheel hub is clamped and limited by the clamping mechanism. According to the diameter of the wheel hub, the position of multiple tool holders on the frame is adjusted simultaneously by the adjusting component, so that the position of the hole required for different wheel hubs varies with the diameter of the wheel hub. Then, the driving component drives multiple tool holders to rotate simultaneously, and the first driving component drives the stamping plate to slide towards one side of the worktable to drill the wheel hub clamped on the worktable.

[0009] Preferably, the adjustment assembly includes an adjustment gear, a drive gear, and a second drive member. The adjustment gear is slidably connected to the frame in a vertical direction. The adjustment gear has multiple arc-shaped grooves, each corresponding to a multiple tool holder. The multiple tool holders are slidably connected to the arc-shaped grooves along their sidewalls. The drive gear is rotatably connected to the frame in a vertical direction and meshes with the adjustment gear. The second drive member is used to drive the rotation of the drive gear.

[0010] By adopting the above technical solution, the drive gear is driven to rotate by the second drive component, and the adjustment gear is rotated by the meshing connection between the drive gear and the adjustment gear. Because the tool holder is slidably connected to the stamping plate along the sliding direction perpendicular to the stamping plate, when the adjustment gear rotates, one end of the adjustment gear moves along the arc groove, thereby causing the tool holder at one end of the stamping plate to move along the sliding direction of the stamping plate. That is, when the adjustment gear rotates, multiple tool holders move together.

[0011] Preferably, the drive assembly includes multiple driven pulleys, a tension pulley, a drive pulley, a timing belt, and a first motor. The multiple driven pulleys are rotatably connected to the frame in a vertical direction, each corresponding to a multiple tool holder. The multiple driven pulleys are slidably connected to the frame in the sliding direction of their respective tool holders, and each tool holder rotates together with its corresponding driven pulley. The drive pulley is rotatably connected to the frame in a vertical direction and slidably connected to the frame in a horizontal direction. The timing belt is simultaneously engaged with both the multiple driven pulleys and the drive pulley. The tension pulley is rotatably connected to the frame in a vertical direction, and its circumferential side abuts against the outer side of the timing belt. The first motor is slidably connected to the frame in the sliding direction of the drive pulley, and one end of the output shaft of the first motor is coaxially and fixedly connected to the drive pulley. The second drive component is used to drive the sliding of the drive pulley.

[0012] By adopting the above technical solution, the first motor drives the drive wheel to move, and the synchronous belt simultaneously engages with the drive wheel and multiple driven wheels, causing the drive wheel and multiple driven wheels to rotate together, thereby causing multiple tool holders to rotate together. When the positions of multiple tool holders are adjusted, the second drive assembly drives the drive wheel to slide, keeping the synchronous belt in a taut state. Through the tensioning pulley, the synchronous belt can engage with multiple driven wheels, reducing the possibility that the tensioning pulley cannot engage with multiple driven wheels simultaneously when the positions of multiple driven wheels change.

[0013] Preferably, the second driving component includes a second motor, a lead screw, and a driven block. The driven block is slidably connected to the frame along the sliding direction of the driving wheel. The driving wheel is rotatably connected to the driven block in the vertical direction. The lead screw is rotatably connected to the frame along the sliding direction of the driven block. The lead screw passes through and is threadedly connected to the driven block. One end of the lead screw is coaxially and fixedly connected to a first bevel gear. A second bevel gear is coaxially and fixedly connected to the driving gear. The first bevel gear and the second bevel gear mesh with each other. The second motor is fixedly connected to the frame. One end of the output shaft of the second motor is coaxially and fixedly connected to the lead screw.

[0014] By adopting the above technical solution, the second motor drives the lead screw to rotate, causing the driven block threadedly connected to the lead screw to move, and the driving wheel on the driven block moves together; and when the second motor drives the lead screw to rotate, it drives the first bevel gear to rotate, thereby causing the second gear meshing with the first bevel gear to rotate, and thus driving the gear to rotate; that is, when the second motor drives the lead screw to rotate, while the driving wheel moves, the positions of multiple tool holders are adjusted so that the synchronous belt is always kept taut.

[0015] Preferably, each of the multiple tool holders is coaxially and fixedly connected to a sliding rod, and the sliding rod has multiple limiting grooves on its axial side. The multiple limiting grooves are evenly distributed around the axis of the sliding rod, and the multiple sliding rods are respectively inserted vertically and slidably connected to the driven wheel.

[0016] By adopting the above technical solution, when the first driving member drives the stamping plate to move, the tool holder moves together with the stamping plate, and the sliding rod moves together with the tool holder, so that the sliding rod moves along the corresponding gear. The limiting groove makes the sliding rod rotate together with the gear. That is, when the tool holder drives the sliding rod to move, the gear can always drive the sliding rod to rotate.

[0017] Preferably, the mounting mechanism includes multiple pressure rods and a third driving member. The multiple pressure rods are rotatably connected to the worktable in the vertical direction. The multiple pressure rods are evenly distributed around the center position of the worktable. The third driving member drives the multiple pressure rods to rotate simultaneously. When the wheel hub is placed on the worktable, the multiple pressure rods abut against the circumferential side of the wheel hub.

[0018] By adopting the above technical solution, the wheel hub is placed on the workbench, and the pressure rod is driven to rotate toward the center of the workbench by the third driving component. This causes multiple pressure rods to simultaneously abut against the circumferential side of the wheel hub, limiting and centering the wheel hub, which facilitates the mounting of the wheel hub.

[0019] Preferably, the third driving component includes an idler wheel, a plurality of sector gears, and a first cylinder. The plurality of sector gears are rotatably connected to the frame in a vertical direction, and each sector gear corresponds to a plurality of pressure rods. The plurality of pressure rods are respectively disposed on the sector gears. The idler wheel is rotatably connected to the frame in a vertical direction and meshes with the plurality of sector gears. The first cylinder is disposed on the frame, and the piston rod of the first cylinder is hinged to any pressure rod in its rotation direction.

[0020] By adopting the above technical solution, the piston movement of the first cylinder drives any pressure rod to rotate, causing the corresponding sector gear to rotate, and the idler gear that meshes with it to rotate. Through the meshing connection between the idler gear and the other sector gears, the other sector gears rotate together, thereby causing the pressure rods on multiple sector gears to rotate together, that is, multiple pressure rods rotate together and rotate at the same angle. When multiple pressure rods abut against the circumferential side of the hub, the hub is limited and centered.

[0021] Preferably, the first driving component includes a sleeve, a screw, and a third motor. The sleeve is rotatably connected to the frame in a vertical direction. One end of the screw is rotatably connected to the stamping plate in the rotation direction of the sleeve. The other end of the screw passes through and is threadedly connected to the sleeve. The third motor is fixedly connected to the frame. One end of the output shaft of the third motor is coaxial and fixedly connected to the sleeve.

[0022] By adopting the above technical solution, the sleeve is rotated by a third motor, and the screw is moved along the axial direction of the sleeve by the threaded connection between the sleeve and the screw, and the stamping plate is moved.

[0023] The main technical effects of this invention are reflected in the following aspects:

[0024] 1. This invention, by setting an adjustment component, drives the drive gear to rotate through the second drive component, and through the meshing connection between the drive gear and the adjustment gear, causes the adjustment gear to rotate; because the tool holder is slidably connected to the stamping plate along the sliding direction perpendicular to the stamping plate, when the adjustment gear rotates, one end of the adjustment gear moves along the arc groove, thereby causing the end of the tool holder located on the stamping plate to move along the sliding direction of the stamping plate; that is, when the adjustment gear rotates, multiple tool holders move together;

[0025] 2. This invention, by setting up a drive assembly, uses a first motor to drive the drive wheel to move, and a synchronous belt simultaneously engages with the drive wheel and multiple driven wheels, causing the drive wheel and multiple driven wheels to rotate together, thereby causing multiple tool holders to rotate together; when the positions of multiple tool holders are adjusted, the second drive assembly drives the drive wheel to slide, keeping the synchronous belt in a taut state, and through the tensioning pulley, the synchronous belt can engage with multiple driven wheels, reducing the possibility that the tensioning pulley cannot engage with multiple driven wheels simultaneously when the positions of multiple driven wheels change;

[0026] 3. The present invention provides a second driving component, in which a second motor drives a lead screw to rotate, causing the driven block threadedly connected to the lead screw to move, and thus the driving wheel on the driven block moves together; and when the second motor drives the lead screw to rotate, it drives the first bevel gear to rotate, thereby causing the second gear meshing with the first bevel gear to rotate, and thus the driving gear to rotate; that is, when the second motor drives the lead screw to rotate, while the driving wheel moves, the positions of multiple tool holders are adjusted so that the synchronous belt is always kept taut.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0034] This application discloses a stamping forming equipment for electric vehicle wheel hubs.

[0035] Reference Figures 1-5 This embodiment of a stamping forming equipment for electric vehicle wheel hubs includes a frame 1, a punching mechanism 2, a clamping mechanism 3, and a first driving component 4. A worktable 11 is fixedly connected to the frame 1, and a stamping plate 12 is slidably connected to the frame 1 in the vertical direction. The first driving component 4 is used to drive the sliding of the stamping plate 12. The first driving component 4 includes a sleeve 41, a screw 42, and a third motor 44. The sleeve 41 is rotatably connected to the frame 1 in the vertical direction. One end of the screw 42 is rotatably connected to the stamping plate 12 in the rotation direction of the sleeve 41, and the other end of the screw 42 is threaded through and connected to the sleeve 41. A first gear is coaxially and fixedly connected to the sleeve 41. The third motor 44 is fixedly connected to the frame 1, and one end of the output shaft of the third motor 44 is coaxially and fixedly connected to the sleeve 41. The third motor 44 drives the sleeve 41 to rotate. Through the threaded connection between the sleeve 41 and the screw 42, the screw 42 moves along the axial direction of the sleeve 41, and the stamping plate 12 moves.

[0036] Reference Figures 1-5The mounting mechanism 3 is used to limit and center the wheel hub placed on the workbench 11. The third driving component 32 includes an idler wheel 321, multiple sector gears 322 and a first cylinder 323. The multiple sector gears 322 are rotatably connected to the frame 1 in the vertical direction. The multiple sector gears 322 correspond to multiple pressure rods 31. One end of the multiple pressure rods 31 in the axial direction is fixedly connected to the corresponding sector gear 322. The idler wheel 321 is rotatably connected to the frame 1 in the vertical direction. The idler wheel 321 is meshed with the multiple sector gears 322. The first cylinder 323 is fixedly connected to the frame 1. The piston rod of the first cylinder 323 is hinged to any pressure rod 31 in its rotation direction.

[0037] Reference Figures 1-5 The piston movement of the first cylinder 323 drives any one of the pressure rods 31 to rotate, causing the corresponding sector gear 322 to rotate, and the idler gear 321, which is meshed with it, to rotate. Through the meshing connection between the idler gear 321 and the other sector gears 322, the remaining sector gears 322 rotate together, causing the pressure rods 31 on multiple sector gears 322 to rotate together, i.e., multiple pressure rods 31 rotate together at the same angle. When multiple pressure rods 31 all abut against the circumferential side of the hub, the hub is limited and centered. The hub is placed on the worktable 11, and the third drive member 32 simultaneously drives the pressure rods 31 to rotate towards the center of the worktable 11, causing multiple pressure rods 31 to simultaneously abut against the circumferential side of the hub, limiting and centering the hub, facilitating hub mounting.

[0038] Reference Figures 1-4 The drilling mechanism 2 is used to drill holes in the hub mounted on the worktable 11. The drilling mechanism 2 includes multiple tool holders 21 for clamping drill bits 211, an adjustment component 22, and a drive component 23. The multiple tool holders 21 are always evenly distributed around the axis of the sleeve 41. The multiple tool holders 21 are slidably connected to the stamping plate 12 along a sliding direction perpendicular to the stamping plate 12. The multiple tool holders 21 are rotatably connected to the stamping plate 12 in a vertical direction. The adjustment component 22 is used to adjust the position of the multiple tool holders 21 on the stamping plate 12 at the same time. The drive component 23 is used to drive the multiple tool holders 21 to rotate at the same time.

[0039] Reference Figures 1-4The adjustment assembly 22 includes an adjustment gear 221, a drive gear 222, and a second drive member 24. The adjustment gear 221 is slidably connected to the frame 1 in the vertical direction. The adjustment gear 221 has multiple arc-shaped grooves 2211, which are evenly distributed around the central axis of the adjustment gear 221. The multiple arc-shaped grooves 2211 correspond to multiple tool holders 21, and the multiple tool holders 21 are slidably connected to the side wall of the arc-shaped grooves 2211. The drive gear 222 is rotatably connected to the frame 1 in the vertical direction and meshes with the adjustment gear 221. The second drive member 24 is used to drive the rotation of the drive gear 222.

[0040] Reference Figures 1-4 The drive assembly 23 includes multiple driven pulleys 231, two tension pulleys 232, a drive pulley 233, a timing belt 234, and a first motor 235. The multiple driven pulleys 231 are rotatably connected to the frame 1 in the vertical direction, each corresponding to a multiple tool holder 21. The multiple driven pulleys 231 are slidably connected to the frame 1 in the sliding direction of their respective tool holders 21, and each tool holder 21 rotates together with its corresponding driven pulley 231. The drive pulley 233 is rotatably connected to the frame 1 in the vertical direction and slidably connected to the frame 1 in the horizontal direction. The timing belt 234 simultaneously engages with the drive assembly. On multiple driven pulleys 231 and driving pulleys 233, two tensioning pulleys 232 are rotatably connected to the frame 1 in the vertical direction. The two tensioning pulleys 232 are located between the driving pulley 233 and multiple driven pulleys 231. The circumferential sides of the two tensioning pulleys 232 abut against the outer side of the synchronous belt 234, so that the synchronous belt 234 can simultaneously mesh with multiple driven pulleys 231. The first motor 235 is slidably connected to the frame 1 along the sliding direction of the driving pulley 233. One end of the output shaft of the first motor 235 is coaxial and fixedly connected to the driving pulley 233. The second driving member 24 is used to drive the sliding of the driving pulley 233.

[0041] Reference Figures 1-4 Multiple tool holders 21 are coaxially and fixedly connected to sliding rods 212. Multiple limiting grooves 2121 are formed on the axial side of each sliding rod 212, evenly distributed around the axis of the sliding rod 212. The sliding rods 212 are vertically inserted and slidably connected to the driven wheel 231. When the first driving member 4 drives the stamping plate 12 to move, the tool holders 21 move together with the stamping plate 12, and the sliding rods 212 move together with the tool holders 21, causing the sliding rods 212 to move along the corresponding gears. The limiting grooves 2121 cause the sliding rods 212 to rotate together with the gears. That is, when the tool holders 21 drive the sliding rods 212 to move, the gears can always drive the sliding rods 212 to rotate.

[0042] Reference Figures 1-4The second driving component 24 includes a second motor 241, a lead screw 242, and a driven block 243. The driven block 243 is slidably connected to the frame 1 along the sliding direction of the driving wheel 233. The driving wheel 233 is rotatably connected to the driven block 243 in the vertical direction. The lead screw 242 is rotatably connected to the frame 1 along the sliding direction of the driven block 243. The lead screw 242 passes through and is threadedly connected to the driven block 243. One end of the lead screw 242 is coaxially and fixedly connected to a first bevel gear 2421. A second bevel gear 2242 is coaxially and fixedly connected to the driving gear 222. The first bevel gear 2421 and the second bevel gear 2242 are meshed. The second motor 241 is fixedly connected to the frame 1. One end of the output shaft of the second motor 241 is coaxially and fixedly connected to the lead screw 242.

[0043] Reference Figures 1-5 The hub to be drilled is placed on the worktable 11, and multiple pressure rods 31 are driven to simultaneously abut against the circumferential side of the hub to clamp and limit its movement. The second motor 241 drives the lead screw 242 to rotate, causing the driven block 243 threadedly connected to the lead screw 242 to move, which in turn causes the driving wheel 233 on the driven block 243 to move as well. When the second motor 241 drives the lead screw 242 to rotate, it drives the first bevel gear 2421 to rotate, which in turn causes the second gear meshing with the first bevel gear 2421 to rotate, which in turn causes the driving gear 222 to rotate. While the driven block 243 drives the driving wheel 233 and the first motor 235 to move, the driving gear 222 drives the adjusting gear 221 to rotate together. That is, when the second motor 241 drives the lead screw 242 to rotate, while the driving wheel 233 moves, the positions of multiple tool holders 21 are adjusted so that the synchronous belt 234 is always kept taut.

[0044] Reference Figures 1-4 When the drive gear 222 rotates, the adjusting gear 221 rotates through the meshing connection between the drive gear 222 and the adjusting gear 221. Since the tool holder 21 is slidably connected to the stamping plate 12 along the sliding direction perpendicular to the stamping plate 12, and the tool holder 21 is vertical, when the adjusting gear 221 rotates, one end of the adjusting gear 221 moves along the arc groove 2211, thereby causing the end of the tool holder 21 located on the stamping plate 12 to move along the sliding direction of the stamping plate 12; that is, when the adjusting gear 221 rotates, multiple tool holders 21 move together.

[0045] Reference Figures 1-4The drive pulley 233 is driven to slide, and when the positions of multiple tool holders 21 are adjusted, the timing belt 234 remains taut. The tensioning pulley 232 allows the timing belt 234 to engage with multiple driven pulleys 231, reducing the possibility that the tensioning pulley 232 cannot simultaneously engage with the multiple driven pulleys 231 when their positions change. The drive pulley 233 is driven to move by the first motor 235, and the timing belt 234 simultaneously engages with both the drive pulley 233 and the multiple driven pulleys 231, causing the drive pulley 233 and the multiple driven pulleys 231 to rotate together, thus causing the multiple tool holders 21 to rotate together.

[0046] Reference Figures 1-4 That is, by adjusting the component 22, the positions of multiple tool holders 21 on the frame 1 are adjusted simultaneously, so that the positions of the holes required for different wheel hubs vary with their diameters; then, the drive component 23 drives the multiple tool holders 21 to rotate simultaneously, and then the first drive component 4 drives the stamping plate 12 to slide toward the worktable 11 to punch holes in the wheel hubs mounted on the worktable 11.

[0047] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
