Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy polishing technology, and in particular to a tooling fixture for polishing aluminum alloy profiles. Background Technology

[0002] Due to its lightweight and high strength properties, aluminum alloy has become the mainstream material for mobile phone frames. After the mobile phone frame is manufactured, the sides of the frame are usually polished for aesthetic purposes and to improve user comfort.

[0003] Chinese Patent Publication No. CN208196484U discloses a fully automatic polishing machine for mobile phone frames, including a fixture mechanism, a material rotation mechanism, a polishing wheel assembly, and a three-dimensional driving mechanism. The fixture mechanism comprises several fixture units, with a mobile phone frame sandwiched between two adjacent fixture units, allowing for simultaneous polishing of multiple mobile phone frames and improving polishing efficiency. The material rotation mechanism drives the fixture mechanism to rotate, and the polishing wheel assembly polishes the mobile phone frames. The three-dimensional driving mechanism is located between the polishing wheel assembly and the material rotation mechanism, driving the polishing wheel assembly or the mobile phone frames to move along the X-axis, Y-axis, and / or Z-axis directions, wherein the X-axis, Y-axis, and Z-axis directions are perpendicular to each other. When the polishing wheel assembly polishes the mobile phone frames, there is no need for manual adjustment of the relative position between the mobile phone frames and the polishing wheel assembly, reducing labor costs and improving efficiency.

[0004] However, this device has the following drawbacks in use: Although the device uses a three-dimensional drive mechanism to drive the polishing wheel assembly or the mobile phone frame to move along the X-axis, Y-axis, and / or Z-axis to polish the mobile phone frame, the three-dimensional drive requires multiple sets of motors and transmission mechanisms, resulting in high equipment operating costs. To address these drawbacks, we propose a tooling fixture for polishing aluminum alloy profiles. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a tooling fixture for polishing aluminum alloy profiles, comprising: tooling and polishing structure.

[0030] The tooling includes a base 10, a track block 11 fixedly mounted on the upper surface of the base 10, a mounting plate 12 slidably mounted on the inner wall of the track block 11, a mobile phone frame positioning component disposed on the mounting plate 12, and a drive component disposed on the upper surface of the base 10 for driving the mounting plate 12 to move.

[0031] The mobile phone mid-frame positioning assembly includes a rotating ring 20 fixedly mounted on the upper surface of the mounting plate 12 by bolts, a support shaft 21 rotatably connected to the inner wall of the rotating ring 20, a connecting shaft 22 fixedly mounted on the upper end of the support shaft 21, a contour block 23 fixedly mounted on the outer surface of the connecting shaft 22, a positioning plate 25 fixedly mounted on the upper end of the connecting shaft 22, a first motor 24 fixedly mounted on the lower surface of the mounting plate 12, and a clamping component disposed on the upper surface of the mounting plate 12. A through hole is provided on the upper surface of the mounting plate 12, and the shaft end of the first motor 24 passes through the through hole and is fixedly connected to the lower end of the support shaft 21. The bottom of the first motor 24 does not contact the upper surface of the base 10. Driving the first motor 24 can drive the connecting shaft 22 to rotate, thereby driving the contour block 23 and the positioning plate 25 on the connecting shaft 22 to rotate synchronously.

[0032] The clamping components include a support frame 50 fixedly mounted on the upper surface of the mounting plate 12, a second cylinder 51 fixedly mounted on the upper surface of the support frame 50, and a clamping plate 52 rotatably mounted on the lower surface of the second cylinder 51. The clamping plate 52 has the same size as the positioning plate 25, and the contour block 23 has the same size as the outer surface of the mobile phone frame. The mobile phone frame can be inserted into the positioning plate 25 for positioning. When the mobile phone frame is inserted into the positioning plate 25, the inner wall of the mobile phone frame will contact the positioning plate 25, thereby lifting the mobile phone frame and using the contour of the positioning plate 25 to limit the displacement of the mobile phone frame. Then, the second cylinder 51 is driven to descend, thereby driving the clamping plate 52 to clamp and fix the mobile phone frame on the positioning plate 25. When the first motor 24 rotates, the clamping plate 52 will rotate synchronously.

[0033] The polishing structure includes a polishing table 30 disposed on the back of the base 10, a mounting base 31 fixedly mounted on the upper surface of the polishing table 30, a polishing wheel 32 and a guide wheel 33 rotatably mounted on the upper surface of the polishing table 30, and a power assembly disposed on the upper surface of the mounting base 31 for driving the polishing wheel 32 to rotate. The power assembly includes a first synchronous wheel 60 rotatably mounted on the upper surface of the mounting base 31, a second motor 61 fixedly mounted on the upper surface of the mounting base 31 via a connecting bracket, and a second synchronous wheel 62 fixedly mounted on the output end of the second motor 61. The first synchronous wheel 60 and the second synchronous wheel 62 are connected by a synchronous belt drive. The shaft end of the first synchronous wheel 60 is fixedly connected to the shaft end of the polishing wheel 32. Driving the second motor 61 can drive the second synchronous wheel 62 to rotate, and the synchronous belt drive can drive the first synchronous wheel 60 to rotate, thereby driving the polishing wheel 32 to rotate.

[0034] The drive assembly includes two first cylinders 40 symmetrically fixedly mounted on the upper surface of the base 10, a connecting plate 41 fixedly mounted on the telescopic end of the first cylinders 40, a shock-absorbing damper 42 fixedly mounted on the back of the connecting plate 41, a connecting plate 43 fixedly mounted on the telescopic end of the shock-absorbing damper 42, and a compression spring 44 sleeved on the surface of the shock-absorbing damper 42. One end of the connecting plate 43 is fixedly connected to one side of the mounting plate 12, one end of the compression spring 44 is fixedly connected to one side of the connecting plate 41, and the other end of the compression spring 44 is fixedly connected to one end of the connecting plate 43. Driving the first cylinders 40 can drive the connecting plate 41 to move, which in turn can drive the connecting plate 43 and the mounting plate 12 to move toward the polishing table 30 until the surface of the contour block 23 contacts the guide wheel 33, at which point the mobile phone frame will contact the polishing wheel 32.

[0035] When the power unit drives the polishing wheel 32 to rotate, the sides of the phone frame can be polished. At the same time, the first motor 24 drives the phone frame to rotate. When the phone frame rotates, the contour block 23 rotates synchronously. When the contour block 23 rotates, the contour block 23 in contact with the guide wheel 33 will generate resistance, which will drive the compression spring 44 to contract and drive the mounting plate 12 to move. Since the compression spring 44 drives the contour block 23 to always contact the guide wheel 33, the polishing wheel 32 always contacts the phone frame, so that the four sides of the phone frame can be polished. The tooling and polishing structure are designed separately, which reduces maintenance costs and facilitates equipment troubleshooting.

[0036] Driven by the first motor 24, the contour block 23 rotates synchronously with the workpiece. Combined with the resistance feedback of the guide wheel 33 and the compression spring 44, the displacement of the mounting plate 12 is automatically adjusted to ensure that the polishing wheel 32 is always in contact with the side of the middle frame, so that the four sides of the middle frame of the mobile phone can be polished. This utility model replaces the traditional three-dimensional drive mechanism through the innovative combination of contour positioning + elastic drive + single-axis synchronous transmission, thereby saving the operating cost of the equipment.

[0037] Specifically, the working principle and operation method of this utility model are as follows:

[0038] Pneumatic clamping: The phone frame is clamped into the positioning plate 25, which is perfectly matched with the inner wall. The contour of the positioning plate 25 restricts the displacement of the phone frame. The second cylinder 51 drives the clamping plate 52 to press down, forming a vertical clamping force on the phone frame with the positioning plate 25 to prevent displacement during polishing.

[0039] Drive and polishing stages

[0040] Linear feed: The first cylinder 40 pushes the connecting plate 41, which drives the mounting plate 12 to move toward the polishing wheel 32 through the shock-absorbing damping 42 and the connecting plate 43, until the contour block 23 contacts the guide wheel 33;

[0041] Rotary polishing: The second motor 61 drives the polishing wheel 32 to rotate at high speed via a synchronous belt, while the first motor 24 drives the support shaft 21 to rotate the mobile phone frame at low speed.

[0042] Dynamic compensation: The contact between the contour block 23 and the guide wheel 33 generates resistance, and the compression spring 44 contracts / extenses in real time to adjust the displacement of the mounting plate 12, ensuring that the polishing wheel 32 maintains a constant contact pressure with the side of the middle frame.

[0043] Multi-faceted polishing

[0044] Continuous rotation: As the mobile phone frame rotates 90° with the contour block 23, the polishing wheel 32 automatically switches to the next side. The resistance feedback of the guide wheel 33 automatically compensates for the workpiece size deviation through the deformation of the compression spring 44, ensuring that the polishing wheel 32 is in continuous contact.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
