Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing technology, specifically to a door lock panel grinding device. Background Technology

[0002] Smart locks offer higher security and convenience compared to traditional mechanical locks. Fingerprint locks are currently the most widely used type of smart lock. During the production of smart locks, the outer casing needs to be polished.

[0003] Chinese Patent No. CN214685923U discloses a magnetic grinding and polishing device for intelligent door lock accessories, including a frame, a support frame, a control panel, and a grinding and polishing chamber. The frame internally houses a drive motor, a rotating disk assembly, a motor support frame, a first hydraulic cylinder, a second hydraulic cylinder, a first stop block, a first fixing block, a second stop block, and a second fixing block. This invention uses the first and second fixing blocks to fix the positions of the first and second hydraulic cylinders. The first and second hydraulic cylinders simultaneously push the motor support frame, which in turn pushes the drive motor to rise or fall. The rotating disk assembly, located inside the support frame, rises or falls with the drive motor, ensuring operator safety. Furthermore, by mounting the drive motor above the motor support frame, the motor support frame provides a base support when the drive motor rotates, preventing the motor from falling due to vibration.

[0004] However, in the above technical solution, the drive motor is only pushed up or down by the motor support frame, and the rotating disk assembly is inside the support frame and rises or falls with the drive motor, ensuring the safety of the operator. However, when grinding multiple smart door lock panels, the door lock panels are prone to movement and collisions caused by the grinding medium when placed in the grinding pot, resulting in damage. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a door lock panel polishing device.

[0006] The technical solution of this utility model is as follows: A door lock panel polishing device includes a polishing machine body connected to a polishing barrel; a limiting component connected to the polishing barrel, the limiting component including a fixing component and a clamping component, the fixing component connected to the polishing barrel, multiple clamping components connected to the fixing component, the fixing component including a fixing plate, a moving plate, an adjusting plate and an adjusting shaft, the adjusting shaft rotatably connected to the polishing barrel, the adjusting plate connected to the adjusting shaft, the adjusting plate having multiple adjusting grooves, multiple fixing plates connected to the polishing barrel, some moving plates slidably connected to the fixing plates, another part of the moving plates connected to the fixing plates, and some moving plates connected to adjusting rods that cooperate with the adjusting grooves; in use, the adjusting shaft and adjusting plate rotate to drive the adjusting rods to move, and some moving plates drive some clamps to move along the fixing plates to form an alternating arrangement; a protective component connected to the polishing machine body; in use, the protective pad of the protective component moves to cooperate with the polishing barrel to form a sealed space.

[0007] Preferably, the fixing component further includes multiple support rings, which are connected to multiple fixing plates.

[0008] Preferably, the multiple support rings are arranged in a nested structure, with the diameter of the support rings gradually increasing from the inside to the outside.

[0009] Preferably, a sliding groove is provided on a portion of the fixed plate, and a sliding block that cooperates with the sliding groove is connected to the movable plate.

[0010] Preferably, the clamping assembly further includes a base plate connected to a movable plate, with protrusions connected to both ends of the base plate; a bidirectional lead screw, one end of which is rotatably connected to any one of the protrusions, and the other end of which passes through the protrusion and is connected to an adjusting handle; two movable seats symmetrically arranged, the movable seats being threadedly connected to the bidirectional lead screw, and multiple clamping rods connected to the movable seats; and two parallel guide rods, the guide rods being arranged on both sides of the bidirectional lead screw, with both ends of the guide rods connected to the protrusions.

[0011] Preferably, the movable seat consists of a support plate, a movable block, a fixed block, a threaded rod, and an adjustment knob. The support plate is threadedly connected to the threaded rod, and a through hole for the guide rod is provided on the support plate. The fixed block is connected to the support plate, and the movable block is arranged parallel to the fixed block. One end of the threaded rod passes through the movable block and is rotatably connected to the fixed block.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, a fixing component and a clamping component are installed inside the polishing barrel. The clamping component fixes the door lock panel and reduces contact with the door lock panel surface while providing stable clamping. This prevents the removal area from being too large, which would affect the surface polishing and require rework. The fixing component can also be configured by moving a portion of the moving plate on the fixing plate to stagger the evenly distributed clamping components around the circumference, thus avoiding obstruction of the polishing medium by the clamping components and the workpiece itself.

[0024] In an optional embodiment, multiple support rings 9 are arranged in a nested structure, with the diameter of the support rings 9 gradually increasing from the inside to the outside; the multiple fixing plates 3 are connected together by the support rings 9, so that the relative positions of the fixing plates 3 can be maintained when they are disassembled and installed.

[0025] In an optional embodiment, a sliding groove 10 is provided on a portion of the fixed plate 3, and a sliding block 11 that cooperates with the sliding groove 10 is connected to the movable plate 4.

[0026] The clamping assembly also includes a base plate 12, a bidirectional lead screw 13, an adjusting handle 14, a movable seat 15, and guide rods 16.

[0028] Example 3

[0029] like Figure 1 As shown, this utility model proposes a door lock panel polishing device. Compared with Embodiment 2, this embodiment describes the detailed structure of the protective component. The protective component includes a support frame 22, a top plate 23, a telescopic device 24, and a cover plate 25. Two support frames 22 are symmetrically arranged and connected to the polishing machine body 1.
