Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, specifically a polishing device for sheet metal parts. Background Technology

[0002] In the field of modern photography, the precision and reliability of cameras are crucial for capturing high-quality images. Among these components, the camera's sheet metal parts, as a vital structural element, not only provide mechanical support but also directly influence the camera's appearance and overall performance.

[0003] However, during the manufacturing process of sheet metal parts, their surface quality is often constrained by many factors, such as limitations of processing technology and the influence of material properties, which may result in defects such as scratches, burrs, unevenness, etc. on the surface of sheet metal parts. In order to facilitate the use of cameras, it is necessary to polish the sheet metal parts at this time.

[0004] In the prior art, there is a sheet metal polishing device, such as the Chinese patent with authorization announcement number CN210010813U entitled "A Polishing Device for the Production of a Hemispherical Camera". The patent discloses a polishing device for the production of a hemispherical camera, which includes a support column. A worktable is provided at the top of the support column, and a working groove is provided on the worktable. A spring is welded to the bottom of the working groove. An adaptation plate is fixedly provided at the other end of the spring, and limit plates are provided on both sides of the top of the adaptation plate. Functional frames are provided on both sides of the top of the worktable.

[0005] The aforementioned patent utilizes a spring-loaded adaptation plate, facilitating both material loading and polishing head operation. The position of the polishing head can be easily adjusted via the main control handle. In known prior art, including the aforementioned patent, when polishing sheet metal parts, a clamping mechanism is first used to fix the sheet metal to improve polishing quality. However, in existing technologies, fixing the sheet metal requires a separate drive source to operate the clamping mechanism, and it is difficult to ensure the sheet metal to be polished is positioned at the machining center during clamping, presenting certain shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a polishing device for sheet metal parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for sheet metal parts, comprising a device body, a support plate vertically and slidably connected to the device body via a cylinder, and a polishing component mounted on the support plate via a servo mechanism; a rotating disk rotatably connected to the device body, and multiple clamping blocks mounted on the rotating disk via guide members, the multiple clamping blocks forming a clamping space for clamping workpieces; a power component for providing power is provided at the bottom of the rotating disk for driving the rotating disk to rotate, and the support plate is connected to the power component via a linkage member.

[0008] Furthermore, the guide includes a guide rod fixedly connected to the clamping block, the guide rod being slidably connected to the device body, and a drive groove is provided on the rotating disk, with the guide rod installed in the drive groove.

[0009] Furthermore, multiple slide rails are fixedly connected to the main body of the device, and each clamping block is slidably connected to the corresponding slide rail.

[0010] Furthermore, a rotating shaft is fixedly connected to the rotating disk, the power component includes a spur gear mounted on the rotating shaft, and a rack is slidably connected to the device body, the rack meshing with the gear.

[0011] Furthermore, the linkage component includes a linkage block fixedly connected to the rack, and the linkage block has a pressure groove. A linkage rod is fixedly connected to the bottom of the bearing plate, and the linkage rod intermittently abuts against the pressure groove.

[0012] Furthermore, a positioning spring is also provided between the rack and the device body.

[0013] Furthermore, the device body has a vertical groove, and the support plate is slidably connected to the vertical groove through a positioning block.

[0014] Furthermore, the polishing assembly includes a polishing motor, and a connecting rod is provided on the output shaft of the polishing motor. A polishing wheel is mounted on the connecting rod by fasteners.

[0015] Furthermore, the fastener includes an extension plate fixedly connected to the connecting rod, and the extension plate is connected to the polishing wheel by fastening bolts.

[0016] Furthermore, the device body is equipped with multiple self-locking casters on its bottom.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: This sheet metal polishing device, through the cooperation of the equipment body, bearing plate, rotating disk, clamping blocks, and linkage components, allows the bearing plate to move downwards via a cylinder. Simultaneously, the linkage components drive the rotating disk to rotate via a power component, and the guide components bring multiple clamping blocks closer together to fix the workpiece. Therefore, during the movement of the bearing plate, the lifting and lowering motion of the bearing plate is linked with the rotational motion of the rotating disk via the linkage components. This eliminates the need for additional motors or cylinders to drive the clamping / releasing actions of the clamping blocks; the lifting and lowering power of the existing polishing components can be used synchronously. Compared with existing technologies, this eliminates the need for a separate clamping drive source, simplifies the overall machine structure, and significantly reduces energy consumption and manufacturing costs.

[0018] Multiple sets of clamping blocks evenly distributed on the rotating disk can synchronously retract or open towards the center with the help of guide components and slide rails as the disk rotates. This symmetrical linkage structure can automatically push the sheet metal part to the center of rotation, ensuring that the geometric center of the sheet metal part coincides with the machining center. This solves the error problem caused by manual adjustment or multiple positioning in the prior art, thereby improving the polishing accuracy and consistency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8 This utility model provides a technical solution: a polishing device for sheet metal parts, including a device body 1, a bearing plate 2 vertically and slidably connected to the device body 1 via a cylinder 5, and a polishing component mounted on the bearing plate 2 via a servo mechanism; a rotating disk 7 is rotatably connected to the device body 1, and multiple clamping blocks 6 are mounted on the rotating disk 7 via guide members, the multiple clamping blocks 6 forming a clamping space for clamping workpiece 21; a power member is provided at the bottom of the rotating disk 7 to drive the rotating disk 7 to rotate, and the bearing plate 2 is connected to the power member through a linkage member.

[0024] Specifically, the sheet metal polishing device includes a main body 1. A support plate 2 is vertically slidably connected to the main body 1 via a cylinder 5, providing power for the vertical sliding of the support plate 2. A polishing component is mounted on the support plate 2 via a servo mechanism (such as a servo motor + lead screw module), which drives the polishing component to move horizontally or within a certain angle range. This enables the polishing component to move along the X, Y, and Z axes on the support plate 2, thus better polishing the workpiece 21. A rotating disk 7 is rotatably connected to the main body 1. Multiple clamping blocks 6 are mounted on the rotating disk 7 via guides. The multiple clamping blocks 6 form a clamping space for clamping the workpiece 21, creating an adjustable clamping space to accommodate sheet metal parts of different sizes. A power component is provided at the bottom of the rotating disk 7 to drive its rotation. The support plate 2 is connected to the power component via a linkage, achieving coordinated control of the lifting and lowering of the polishing component and the synchronous movement of the clamping blocks 6. Specifically, during use, when the cylinder 5 drives the support plate 2 downward, the linkage drives the rotating disk 7 to rotate via the power component. This, in turn, causes multiple clamping blocks 6 to move closer together via the guide component, thus fixing the workpiece 21. Therefore, during the movement of the support plate 2, the linkage links the lifting and lowering motion of the support plate 2 with the rotational motion of the rotating disk 7. This allows the clamping / releasing action of the clamping blocks 6 to be completed synchronously without the need for an additional motor or cylinder 5, relying solely on the lifting power of the existing polishing components. Compared to existing technologies, this eliminates the need for a separate clamping drive source, simplifies the overall machine structure, and significantly reduces energy consumption and manufacturing costs.

[0025] In the embodiments provided by this utility model, the guide component includes a guide rod 9 fixedly connected to the clamping block 6. The guide rod 9 is slidably connected to the device body 1, and a drive groove 8 is provided on the rotating disk 7, with the guide rod 9 installed in the drive groove 8. The trajectory of the drive groove 8 is designed as an involute or an eccentric arc, so that when the rotating disk 7 rotates, the guide rod 9 slides along the groove, driving the clamping block 6 to move radially. The other end of the guide rod 9 is slidably connected to a linear bearing on the device body 1 to ensure the stability of the movement direction of the clamping block 6 and prevent deviation.

[0026] In the embodiments provided by this utility model, multiple slide rails 10 are fixedly connected to the device body 1, and each clamping block 6 is slidably connected to the corresponding slide rail 10. The slide rails 10 are high-precision linear guides, and each slide rail 10 is equipped with a slider, which is fastened to the bottom of the clamping block 6 by screws. The slide rails 10 and the drive groove 8 work together to keep the clamping block 6 on a straight trajectory when moving radially, reducing frictional resistance and improving clamping accuracy.

[0027] In the embodiment provided by this utility model, a rotating shaft 11 is fixedly connected to the rotating disk 7. The power component includes a spur gear 12 mounted on the rotating shaft 11, and a rack 13 is slidably connected to the device body 1, meshing with the gear. The spur gear 12 is keyed to the rotating shaft 11, and a horizontal slide rail 10 is installed on the side wall of the device body 1. The rack 13 is embedded in the slide rail 10 and meshes with the spur gear 12. One end of the rack 13 is connected to a cylinder 5 or a manual push rod. When the rack 13 is pushed to move linearly, the spur gear 12 drives the rotating disk 7 to rotate, realizing the synchronous opening and closing of the clamping block 6.

[0028] In the embodiments provided by this utility model, the linkage includes a linkage block 14 fixedly connected to the rack 13, and a pressure groove 15 is provided on the linkage block 14. A linkage rod 16 is fixedly connected to the bottom of the bearing plate 2, and the linkage rod 16 intermittently abuts against the pressure groove 15. When the bearing plate 2 descends, the linkage rod 16 pushes the linkage block 14 to move horizontally, thereby driving the rack 13 to drive the rotating disk 7 to rotate, so that the clamping block 6 clamps the workpiece 21.

[0029] In the embodiment provided by this utility model, a positioning spring 17 is also provided between the rack 13 and the equipment body 1. When the linkage rod 16 disengages from the pressure groove 15, the spring force causes the rack 13 to reset, the rotating disk 7 rotates in the opposite direction, and the clamping block 6 automatically releases the sheet metal part. The spring parameters (such as stiffness and pre-compression amount) can be adjusted according to the parameters of the workpiece 21 to ensure reset stability.

[0030] In the embodiments provided by this utility model, a vertical groove is provided on the device body 1, and the bearing plate 2 is slidably connected to the vertical groove through a positioning block to improve the stability of the bearing plate 2 when sliding.

[0031] In the embodiments provided by this utility model, the polishing assembly includes a polishing motor 3, a connecting rod 18 is provided on the output shaft of the polishing motor 3, and a polishing wheel 4 is mounted on the connecting rod 18 by fasteners. The motor output shaft is connected to the connecting rod 18 via a coupling. The connecting rod 18 has a hollow structure to reduce weight, and the polishing wheel 4 is mounted at its end by fasteners. The polishing wheel 4 is made of replaceable nylon fiber or abrasive wheel material, and the motor speed is adjusted by a frequency converter (e.g., 1000-3000 rpm) to adapt to different surface roughness requirements.

[0032] In the embodiments provided by this utility model, the fastener includes an extension plate 19 fixedly connected to the connecting rod 18, and the extension plate 19 is connected to the polishing wheel 4 by a fastening bolt 20. The polishing wheel 4 (4) has a corresponding mounting hole in the center, and is locked to the extension plate 19 by the fastening bolt 20, which facilitates the installation and disassembly of the polishing wheel 4.

[0033] In the embodiments provided by this utility model, a plurality of self-locking moving wheels are provided on the bottom of the equipment body 1. By setting the self-locking moving wheels, the equipment can move flexibly in the workshop, and the equipment stability is ensured after locking.

[0034] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources, and this application is equipped with a control system for controlling the operation of the entire equipment.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.
