Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic product processing technology, and in particular relates to a polishing device for plastic housings of electronic components. Background Technology
[0002] Plastic housings for electronic components are specially designed and manufactured plastic shells for encapsulating and protecting various electronic components. These housings not only provide physical protection for the internal electronic components, preventing them from mechanical damage, moisture, dust, and other contaminants, but also offer a certain degree of electrical insulation. Polishing, as a key step in the plastic housing manufacturing process, plays an indispensable role in improving the appearance quality and performance of the housing.
[0003] In existing plastic shell polishing processes, a cylindrical cage-like fixture is typically used to hold the plastic shells to be polished. This fixture has multiple independent loading chambers for placing the plastic shells, each with a rotatable and closable protective mesh structure. During loading, the operator must first manually rotate and open the protective mesh to open the loading chamber, then place the plastic shells to be polished one by one into the chamber, and then rotate and close the protective mesh to fix the position of the plastic shells. After loading one chamber, the operator must repeat the above steps to fill the other loading chambers until the entire fixture is full. However, during each loading process, the protective mesh needs to be unlocked and relocked, which is not only cumbersome but also prone to improper operation that results in the protective mesh not closing completely, thus affecting the safety and stability of the polishing process.
[0004] Therefore, there is a particular need for a polishing device for plastic housings of electronic components to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of traditional cage-type clamps, which rely on manual operation for each plastic housing during polishing and loading, resulting in a cumbersome process and potential safety and stability issues due to incomplete mesh closure, this invention provides a polishing device for plastic housings used in electronic components.
[0006] This utility model is achieved through the following technical approach: a polishing device for plastic housings of electronic components, comprising a connecting plate, a sleeve, a placement rack, a support block, a guide rod, a locking block, a sliding block, a spring, a rotating ring, a wedge block, and a positioning assembly. A connecting plate is fixed to both ends of the sleeve. Multiple placement racks arranged in a circular array are slidably placed between the two connecting plates. A rotating ring is rotatably mounted on one side of one connecting plate. Multiple support blocks evenly distributed along the center of one of the connecting plates are fixed to one side of the connecting plate. A sliding block is slidably mounted on each support block. A locking block is fixed to the top. Each placement rack has a locking slot on one side. The number of locking blocks and locking slots are the same, and they are inserted into the corresponding locking slots. Two symmetrically distributed guide rods are fixed inside each support block. The guide rods pass through the corresponding locking block and are slidably connected to it. A spring is sleeved on the outside of each guide rod. The two ends of the spring are fixedly connected to the corresponding support block and the corresponding locking block, respectively. Multiple wedge blocks are fixed to the inner ring of the rotating ring and are evenly distributed along its center. The rotation trajectory of the wedge blocks intersects with the position of the sliding block. The positioning component is set on one side of one of the connecting plates.
[0007] More preferably, the positioning component includes a fixed block, a second spring, a movable block, and a second guide rod. A slot is provided on the rotating ring. A fixed block is fixedly connected to one side of one of the connecting discs. Two guide rods are symmetrically distributed and fixedly connected to the fixed block. A movable block is slidably arranged between the two guide rods. The shape of the movable block is adapted to the slot. A spring is sleeved on the outside of each guide rod. The two ends of the spring are fixedly connected to the fixed block and the movable block, respectively.
[0008] More preferably, it also includes a handle, with one handle fixed to one side of each shelf.
[0009] More preferably, it also includes rollers, with one roller rotatably disposed on each wedge block.
[0010] More preferably, it also includes wheels, with multiple three-wheeled units evenly distributed on the side of the movable block near the rotating ring, the wheels contacting the outer surface of the rotating ring.
[0011] More preferably, it also includes a pull block, with the pull block fixed to the side of the movable block away from the rotating ring.
[0012] Beneficial effects: By driving the wedge block, sliding block, and locking block through the rotating ring, multiple placement racks can be unlocked and locked simultaneously without having to operate them one by one, simplifying the loading process and improving operational convenience and safety. At the same time, the movable block in the positioning component cooperates with the second slot to achieve precise control of the rotation angle of the rotating ring, improving operational accuracy.

Detailed Implementation
[0020] Example: A polishing apparatus for plastic housings of electronic components, such as... Figures 1-6As shown, the assembly includes a connecting plate 1, a sleeve 2, a placement frame 3, a handle 4, a support block 5, a guide rod 51, a locking block 6, a sliding block 7, a spring 8, a rotating ring 9, a wedge block 10, a roller 11, and a positioning component. A connecting plate 1 is fixedly connected to both ends of the sleeve 2. Six placement frames 3 arranged in a circular array are slidably placed between the two connecting plates 1. A handle 4 is fixedly connected to the right side of each placement frame 3, facilitating the operator to pull the placement frame 3 for loading and unloading operations. A rotating ring 9 is rotatably mounted on the right side of the right connecting plate 1, with six grips fitted on the outer ring of the rotating ring 9 for easy rotation by the operator. Six support blocks 5 are fixedly connected to the right side of the right connecting plate 1, evenly distributed along its center. A sliding block 7 is slidably mounted on each support block 5, and a locking block 6 is fixedly connected to each sliding block 7. A locking slot 41 is opened on the right side of each placement frame 3, with one locking block 6 and one locking slot 41. The mounting bracket 3 is locked in its current position by inserting it into the corresponding slot 41. Each support block 5 has two symmetrically distributed guide rods 51 fixedly connected inside. The guide rods 51 slide through the corresponding locking block 6 and are slidably connected to it. Each guide rod 51 is fitted with a spring 8 on its outside. The two ends of the spring 8 are fixedly connected to the corresponding support block 5 and the corresponding locking block 6, respectively, to provide a reset force for the locking block 6. The inner ring of the rotating ring 9 is fixedly connected with six wedge blocks 10 evenly distributed along its center. The rotation trajectory of the wedge blocks 10 intersects the position of the sliding block 7. When the rotating ring 9 rotates, the wedge blocks 10 can squeeze the sliding block 7, causing the locking block 6 to move towards the center of the rotating ring 9, thereby releasing the lock on the mounting bracket 3. Each wedge block 10 is rotatably provided with a roller 11 to ensure that the wedge block 10 moves smoothly when it is disengaged from the sliding block 7, reducing frictional resistance. The positioning component is located on the right side of the right connecting plate 1. The placement rack 3 is provided with a cavity for placing plastic shells to be polished. Multiple plastic shells to be polished can be placed in the cavity along its length. The open side of the cavity faces outward toward the sleeve 2 so that the polishing material can pass through the strip hole on the sleeve 2 from the outside, interact with the plastic shell to achieve polishing, and flow out from the hole on the placement rack 3.
[0021] like Figure 5 and Figure 6As shown, the positioning assembly includes a fixed block 12, a second spring 13, a movable block 14, a second guide rod 141, a wheel 15, and a pulling block 16. A slot 91 is provided on the rotating ring 9. The right side of the right connecting plate 1 is fixedly connected to the fixed block 12. Two symmetrically distributed guide rods 141 are fixedly connected to the fixed block 12. A movable block 14 is slidably disposed between the two guide rods 141. The shape of the movable block 14 is adapted to the slot 91. A second spring 16 is sleeved on the outside of each guide rod 141. 3. The two ends of the spring 13 are fixedly connected to the fixed block 12 and the movable block 14 respectively, providing a reset force for the movable block 14. The movable block 14 is rotatably provided with three equally spaced wheels 15 on the side close to the rotating ring 9. The wheels 15 contact the outer ring surface of the rotating ring 9. When the rotating ring 9 rotates and contacts the movable block 14, the wheels 15 can convert the traditional sliding friction into rolling friction, reduce wear and improve the smoothness of operation. The movable block 14 is fixedly connected to the side away from the rotating ring 9 with a pulling block 16.
[0022] In the initial state, wheel 15 contacts the outer surface of rotating ring 9, and spring 13 is in a compressed state;
[0023] When this device is needed, the operator first rotates the rotating ring 9 counterclockwise, so that the wedge block 10 rotates with the rotating ring 9 and gradually contacts and squeezes the sliding block 7. After the sliding block 7 is under pressure, it drives the locking block 6 to move towards the center of the rotating ring 9, thereby disengaging from the slot 41 and releasing the lock on the placement rack 3. As the locking block 6 moves, the spring 8 is compressed.
[0024] When the wedge block 10 rotates to the appropriate position and the locking block 6 completely disengages from the locking slot 41, the movable block 14 is aligned with the locking slot 91. At this time, the spring 13 quickly returns to its original state, pushing the movable block 14 to move toward the center of the rotating ring 9 and accurately locking into the locking slot 91, thus achieving precise positioning of the rotating ring 9.
[0025] The operator then pulls out each placement rack 3 to the right in sequence, places the plastic shell to be polished on it, and pushes the placement rack 3 back to its original position to complete the loading. After loading, the operator pulls the movable block 14 outward to disengage it from the slot 2 91, and the spring 2 13 is compressed accordingly. Then, the rotating ring 9 is rotated clockwise to disengage the wedge block 10 from the sliding block 7. At this time, the spring 1 8 returns to its original state and pushes the locking block 6 to re-engage into the slot 1 41, locking the position of all placement racks 3 again, completing the clamping preparation, and entering the polishing stage.
