Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing equipment, and more particularly to a polishing device. Background Technology
[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Traditional polishing machines typically operate by using an electric motor to drive a polishing wheel at high speed. The polishing wheel and polishing compound work together to rub against the surface, removing paint contamination, oxide layers, and shallow scratches. However, the polishing wheel is usually driven directly by various cylinders when it approaches the workpiece. Fixed parameters control the wheel's movement to a predetermined distance to contact the workpiece and perform polishing. This results in a polishing force being applied to the workpiece during the polishing process, which can damage the internal structure of the workpiece. Therefore, this application proposes a solution to this problem. Summary of the Invention
[0003] Purpose of the utility model: The purpose of this utility model is to provide a polishing device that can reduce the polishing force of the polishing wheel on the workpiece and avoid damage to the workpiece caused by the polishing force.
[0004] Technical solution: The polishing device of this utility model includes a frame structure, which includes a mounting top plate and a mounting bottom plate. The mounting top plate and the mounting bottom plate are fixedly connected by multiple mounting guide shafts. The device is characterized in that: a transmission mechanism is provided on the mounting guide shafts, and the transmission mechanism is connected to a polishing mechanism; a transfer mechanism is provided on the mounting bottom plate; the polishing part is placed on a mounting seat in the transfer mechanism, facing the polishing wheel in the polishing mechanism; and an elastic mechanism is provided at the bottom of the mounting seat, which elastically supports the mounting seat.
[0005] Preferably, the transmission mechanism includes an electric cylinder, multiple linear bearings, and opposing guide mounting plates. The electric cylinder is located on the top of the mounting plate, the linear bearings are mounted on the mounting guide shaft, the opposing guide mounting plates are fixed on the linear bearings, and a polishing mechanism is fixedly arranged between the opposing guide mounting plates.
[0006] The electric cylinder acts as the power source for the linear bearing, driving the linear bearing to move up and down along the mounting guide shaft. This, in turn, drives the guide mounting plate, which is fixedly mounted to the linear bearing, to move up and down, and consequently drives the polishing mechanism to move up and down.
[0007] Preferably, there are at least two linear bearings on the mounting guide shaft where the linear bearings are installed.
[0008] The arrangement of multiple linear bearings on the same mounting guide shaft is to make the motion more stable and the control more precise.
[0009] Preferably, the polishing mechanism includes a polishing wheel and a polishing wheel mounting plate. The polishing wheel mounting plate is fixedly connected to the transmission mechanism, and the polishing wheel is installed inside the polishing wheel mounting plate, facing the mounting seat in the transfer mechanism.
[0010] The polishing wheel is fixedly connected to the polishing mounting plate, and the polishing mounting plate is fixedly connected to the transmission mechanism, so that the polishing wheel is driven by the transmission mechanism to complete the adjustment of its vertical displacement.
[0011] Preferably, an upper and lower connecting plate is provided between the mounting top plate and the mounting bottom plate, and a spray valve is provided between the upper and lower connecting plates, with the valve port of the spray valve facing the mounting seat in the transfer mechanism.
[0012] The spray valve facilitates the application of polishing agent to the workpiece, improving the polishing effect of the polishing wheel.
[0013] Preferably, the transfer mechanism includes a linear module, a slider, an elastic mechanism, and a mounting base. The linear module is mounted on a mounting base plate, and a slider with a sliding connection is provided on the linear module. The mounting base is fixed to the slider by the elastic mechanism.
[0014] The position of the linear module mounting base is adjusted to facilitate placing the workpiece to be polished into the mounting base and then transferring the workpiece to be polished under the polishing wheel.
[0015] Preferably, a dual-axis cylinder for clamping the polished part is provided on either side of the mounting base, with the output end of the dual-axis cylinder facing the side of the polished part in the mounting base.
[0016] The output end of the dual-axis cylinder applies pressure to the side of the workpiece to be polished, which, together with the side wall of the mounting base on the other side of the workpiece, more firmly places the workpiece inside the mounting base, preventing the workpiece from shifting or even falling out of the mounting base due to the polishing force during the polishing process.
[0017] Preferably, the elastic mechanism consists of multiple springs, which are evenly distributed between the slider and the mounting base.
[0018] The elastic mechanism uses multiple springs so that when the workpiece is subjected to polishing force, the mounting seat compresses the springs, causing the workpiece to descend and reducing the polishing force it bears.
[0019] Beneficial effects: Compared with the prior art, this utility model has the following advantages:
[0020] (1) The present invention uses an elastic mechanism provided under the mounting base so that when the polishing part is subjected to polishing force, the mounting base compresses the spring, causing the polishing part to drop down and reducing the polishing force it bears.
[0021] (2) By setting up a dual-axis cylinder, the workpiece to be polished is more firmly set in the mounting base and will not be displaced due to the polishing force.
[0022] (3) By setting multiple linear bearings on the mounting guide shaft, this utility model improves the stability of the electric cylinder's control over the up and down displacement of the polishing mechanism, enabling the polishing wheel to reach the polishing point more accurately and improving the polishing effect.

The mounting top plate 1 and the mounting bottom plate 2 are fixedly connected by four mounting guide shafts 3, which are respectively set on the four corners of the cuboid space formed by the mounting top plate 1 and the mounting bottom plate 2.
[0029] In this embodiment, a transmission mechanism is provided on the mounting guide shaft 3. The transmission mechanism includes an electric cylinder 4, multiple linear bearings 5, and opposing guide mounting plates 6. The electric cylinder 4 is located on the top of the mounting top plate 1. The linear bearings 5 are mounted on the mounting guide shaft 3. The opposing guide mounting plates 6 are fixed on the linear bearings 5. A polishing mechanism is fixedly arranged between the opposing guide mounting plates 6. The electric cylinder 4 serves as the power source for the linear bearings 5, driving the linear bearings 5 to move up and down along the mounting guide shaft 3, thereby driving the guide mounting plates 6 fixedly mounted to the linear bearings 5 to move up and down, and further driving the polishing mechanism to move up and down.
[0030] In this embodiment, two linear bearings 5 are provided on the same mounting guide shaft 3. The purpose of providing two linear bearings 5 is to make the movement more stable and the control more precise.
[0031] In this embodiment, the polishing mechanism includes a polishing wheel 7 and a polishing wheel mounting plate 8. The polishing wheel mounting plate 8 is fixedly connected to the transmission mechanism. The polishing wheel 7 is installed inside the polishing wheel mounting plate 8 and faces the mounting seat 9 in the transfer mechanism.
[0032] In this embodiment, an upper and lower connecting plate 10 is provided between the top mounting plate 1 and the bottom mounting plate 2, and a spray valve 11 is provided between the upper and lower connecting plates 10. The valve port of the spray valve 11 faces the mounting seat 9 in the transfer mechanism to spray polishing agent and improve the polishing effect.
[0033] In this embodiment, the transfer mechanism includes a linear module 12, a slider 13, an elastic mechanism 14, and a mounting base 9. The linear module 12 is mounted on the mounting base plate 2, and the slider 13 is slidably connected to the linear module 12. The mounting base 9 is fixed to the slider 13 by the elastic mechanism 14. The position of the mounting base 9 is adjusted by the linear module 12 to facilitate the placement of the workpiece to be polished into the mounting base 9 and then the workpiece to be polished is transferred to the area below the polishing wheel 7.
[0034] In this embodiment, a dual-axis cylinder 15 for clamping the polished part is provided on the left side of the mounting base 9. The output end of the dual-axis cylinder 15 faces the side of the polished part in the mounting base 9. It cooperates with the inner wall of the mounting base 9 on the other side of the part to be polished, so as to more firmly place the part to be polished inside the mounting base 9 and prevent the part to be polished from being displaced or even falling out of the mounting base 9 due to the polishing force during the polishing process.
[0035] In this embodiment, the elastic mechanism 14 consists of multiple springs, which are evenly distributed between the slider 13 and the mounting base 9. When the workpiece to be polished is subjected to polishing force, the mounting base 9 compresses the springs, causing the workpiece to descend and reducing the polishing force borne by the workpiece.
