Description

Technical Field

[0001] This utility model belongs to the technical field of bronze mirror processing equipment, specifically relating to a bronze mirror edge polishing device. Background Technology

[0002] Traditional bronze mirror edge polishing equipment typically uses polishing heads that are fixed at a single angle or are very difficult to adjust. For bronze mirror edges with curved surfaces or complex contours, it is impossible to ensure that the polishing block always fits the workpiece at the optimal angle, resulting in uneven polishing, low efficiency, and even potential damage to the workpiece.

[0003] Many devices rely on manual feeding or simple pneumatic / hydraulic drives, making it difficult to achieve stable, high-frequency micro-reciprocating motions. This results in unstable polishing pressure, fluctuating between high and low pressures, affecting the consistency of polishing and the surface finish.

[0004] Low level of automation and flexibility: A single machine can often only handle the edges of one or a few fixed shapes of bronze mirrors. When different styles or sizes of bronze mirrors need to be polished, a lot of time is required to readjust or even change the tooling, making it unable to adapt to the flexible production needs of small batches and multiple varieties. Summary of the Invention

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a device for polishing the edge of a copper mirror.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a copper mirror edge polishing device, including a mounting bracket, the mounting bracket being C-shaped, a polishing module being provided inside the mounting bracket, the polishing module being rotatably connected to the mounting bracket, the polishing module including two connecting plates, two support rods being connected between the two connecting plates, a mounting plate being installed in the middle position of the two support rods, a reciprocating motor being provided at the upper end of the mounting plate, and a cam disk being fixedly connected to the drive end, a sliding frame being slidably connected to the front surface of the mounting plate, and a polishing block being installed in the sliding frame, a connecting frame being connected to the top of the sliding frame, a pin being provided on both the connecting frame and the cam disk, and a connecting rod being connected between the two pins, the rotation of the cam disk realizing the up-down reciprocating movement of the sliding frame through the connecting rod.

[0007] Preferably, both connecting plates in the polishing module are provided with sliding grooves, and each end of the mounting bracket is provided with a swing motor.

[0008] Preferably, the drive end of the swing motor is provided with a step.

[0009] Preferably, the polishing module is locked to the drive end of the swing motor by a nut through a groove on the connecting plate.

[0010] Preferably, the grooves in the two connecting plates of the polishing module are arranged parallel to each other.

[0011] The beneficial effects of this invention are as follows: The entire core polishing module is hinged to the drive end of the swing motor via connecting plates at both ends, forming a suspension system that can swing as a whole. This allows the polishing blocks mounted on the module to change their tilt angle according to a preset program or external command, thereby perfectly conforming to the edges of copper mirrors with different curvatures and achieving all-round, dead-angle-free polishing;

[0012] A reciprocating motor drives a cam disk, which in turn converts the rotary motion into precise linear reciprocating motion of the sliding frame via a connecting rod. This mechanical transmission ensures stable, high-frequency, short-stroke feeding of the polishing block, guaranteeing the uniformity and consistency of polishing pressure, which is beneficial for obtaining higher surface quality.

[0013] The polishing module is mounted on the oscillating motor via a groove and nut on the connecting plate. This connection method not only enables the oscillation function but also allows for fine-tuning of the module's position or quick disassembly and replacement. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A device for polishing the edge of a bronze mirror, such as Figures 1-2As shown, the device includes a C-shaped mounting bracket. A polishing module is installed inside the mounting bracket and is rotatably connected to it. The polishing module includes two connecting plates connected by two support rods. A mounting plate is installed between the two support rods. A reciprocating motor is located at the upper end of the mounting plate, and a cam disk is fixedly connected to the drive end. A sliding frame is slidably connected to the front surface of the mounting plate, and a polishing block is installed inside the sliding frame. A connecting frame is connected to the top of the sliding frame. Both the connecting frame and the cam disk have a pin, and a connecting rod connects the two pins. The rotation of the cam disk enables the sliding frame to reciprocate up and down via the connecting rod.

[0019] The polishing module has sliding grooves on both connecting plates, and a swing motor is provided at both ends of the mounting bracket. The drive end of the swing motor is provided with a step. The polishing module is locked to the drive end of the swing motor by nuts through the sliding grooves on the connecting plates. The sliding grooves in the two connecting plates of the polishing module are arranged parallel to each other.

[0020] The principle of this invention: The core working principle of this device is to use two motors to drive the macroscopic angular oscillation of the polishing module and the microscopic high-frequency reciprocating motion of the polishing head, thereby efficiently and accurately completing the adaptive polishing of the edge of the complex curved copper mirror.

[0021] The device is fixed to one side of the clamp that supports the rotation of the copper mirror and placed in the "mouth" of the C-shaped mounting bracket, so that the edge to be polished faces the polishing module.

[0022] The drive ends (with stepped shafts) of the two swing motors rotate synchronously, causing the entire polishing module (fixed to it by the slide and nut on the connecting plate) to swing around the drive shaft axis.

[0023] This action is used to adjust the cutting angle of the polishing block relative to the edge of the bronze mirror, ensuring that the polishing block can fit on the bronze mirror at the optimal working angle, regardless of whether the edge of the bronze mirror is vertical, inclined or curved.

[0024] The reciprocating motor mounted on the module mounting plate starts and drives the cam disk to rotate. The rotational motion of the cam disk is transmitted to the pin on the top of the sliding frame through the pin and connecting rod connected to it, so that the rotation of the cam disk is precisely converted into high-frequency, short-stroke linear reciprocating motion of the sliding frame on the mounting plate.

[0025] The polishing block, mounted within the sliding frame, reciprocates at high speed, rubbing and polishing the edge of the copper mirror that is pressed against it. This reciprocating motion provides stable and uniform polishing pressure, which is crucial for ensuring polishing quality and surface consistency.

[0026] Throughout the process, the reciprocating motor operates continuously, ensuring that the polishing block is always performing efficient polishing operations regardless of changes in angle.

[0027] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
