Technical Field

[0001] The invention relates to the technical field of metal mirror processing, and in particular to a metal mirror processing device and process. Background Art

[0002] Metal mirrors are widely used in precision instruments, automobile manufacturing, electronic devices and consumer products. Metal mirror processing eliminates microscopic defects on the surface of the material through physical or chemical methods to form a uniform, flat surface with extremely strong light reflective ability. It is often used in the production of laser reflectors and sensors for precision instruments, watches, decorative parts, car lights and chrome-plated parts, etc. The existing processing equipment still has some defects.

[0003] For example, the invention patent with publication number CN110369771A discloses a metal workpiece processing device, in which a rotating plate is driven by a motor to rotate. The driven shaft and the first gear arranged at the eccentric part of the rotating plate revolve around the output shaft while rotating under the action of the annular rack, thereby driving the eccentric plate to follow the movement. The eccentric plate uses the rod assembly to drive the rotating shaft and the milling cutter to reciprocate and rotate at the same time, thereby realizing circumferential milling of the circular workpiece. During milling, the milling cutter also rotates under the action of the spur rack and the second gear, thereby improving the processing efficiency. In addition, the device can also process workpieces of different specifications and sizes.

[0004] Although the above-mentioned device can be used for workpieces of different sizes, it is not possible to perform mirror processing on the inner wall edge of a recessed workpiece at a specific angle when in use.

[0014] As a preferred solution of the present invention, a rotating block is rotatably installed on the magnetic block, a connecting disk is fixedly connected to the rotating block, an opening for the magnetic metal damping plate to move is opened on the connecting shell, and second limit blocks are fixedly connected to both sides of the magnetic metal damping plate.

[0015] A metal mirror processing process comprises the following steps: S1: The front-to-rear position and left-to-right position of the first support seat are adjusted by the electric slide seat above the base, so that the central axis of the first support seat and the support plate are aligned with the milling assembly, and then the annular workpiece can be placed in the middle of the three jaws on the three-jaw chuck. The driving plate is rotated by adjusting the assembly. When the driving plate rotates, it will drive the three jaws on the three-jaw chuck to shrink or expand synchronously, thereby completing the fixing of the annular workpiece. The position of the magnetic metal damping plate is adjusted by extending the third electric push rod, thereby changing the initial position of the workpiece and the contact surface resistance at the bottom of the workpiece; S2: The initial height of the support block is adjusted by the first electric push rod. The driving assembly is used to drive the milling assembly to rotate and change the height of the milling assembly. The milling assembly can perform mirror processing on the inner wall edge of the annular workpiece during milling. The multi-layer milling assembly can process annular workpieces of different sizes. S3: When it is necessary to switch the processing mode, turn off the driving component to keep the milling component stationary. By abutting different surfaces of the fixed component with the outer surface of the workpiece, different parts can be adapted for use. The first motor on the first support seat drives the support plate to rotate, thereby rotating the workpiece for milling processing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the milling assembly and driving assembly, the key rod is driven to rotate by the second motor on the driving assembly, and the key rod drives the key cylinder and the milling assembly to rotate, and the surface of the workpiece is mirror-processed by the first milling tool and the second milling tool on the milling assembly. During the processing, the key cylinder can be moved downward by extending the second electric push rod, and the mirror surface is pressed down by the milling tool lowered by the key cylinder, so that the device can mirror-process the inner wall of the workpiece. Since the outer edge of the second milling tool is provided with a tapered notch, the device can fit the tapered notch to the edge of the inner wall of the annular workpiece to perform mirror processing. Since the second milling tool is nested in multiple layers and the taper of the tapered notch at the bottom of each milling tool is different, the device can perform mirror processing at a specific angle on the inner wall edge of the recessed structure workpiece, which solves the problem that the existing mirror processing equipment cannot perform mirror processing at a specific angle on the inner wall edge of the recessed workpiece. The device has the advantage of greater adaptability.

[0017] 2. Through the first support seat, the first motor and the support plate on the device, the device can choose to switch the rotating tool for processing or the rotating workpiece for processing according to the needs of mirror processing. The processing efficiency of the device can also be improved by rotating the tool forward and the workpiece reversely, thereby enhancing the applicability of the device and solving the problem that the existing processing equipment cannot switch between rotating workpiece processing and rotating tool processing.

[0018] 3. By setting the magnetic block, rotating block, connecting disk and magnetic metal damping plate, the initial height of the magnetic block is changed by adjusting the elongation of the third electric push rod, so that the distance from the magnetic block to the magnetic metal damping plate changes. It can not only change the position of the magnetic metal damping plate on the connecting shell, thereby adjusting the resistance of the contact surface at the bottom of the workpiece, but also adjust the adsorption effect of the magnetic metal damping plate on the workpiece. The three-jaw chuck can be deactivated later, and the workpiece can be fixed and processed only by adsorbing the magnetic metal damping plate, so that the workpiece can be mirror-finished under the condition of flexible clamping and fixing, which is suitable for mirror-finishing thin-walled workpieces, thereby enhancing the application scope of the device.

When the drive plate 7 rotates, it drives the three claws 9 on the three-jaw chuck 8 to shrink or expand synchronously, thereby completing the fixing of the annular workpiece. The position of the magnetic metal damping plate 20 is adjusted by extending the third electric push rod 15, thereby changing the initial height of the workpiece and the contact surface resistance at the bottom of the workpiece.

[0035] like Figure 1-Figure 3 and Figure 5-Figure 10As shown, the initial height of the support block 23 is adjusted by the first electric push rod 10, the driving assembly 11 is used to drive the milling assembly 12 to rotate and change the height of the milling assembly 12, the second motor 1101 on the support block 23 drives the key rod 1102 to rotate, the key rod 1102 drives the key cylinder 1103 to rotate on the outer bushing 1106, and the first milling tool 1201 and the second milling tool 1202 on the milling assembly 12 are driven to rotate through the key cylinder 1103, thereby realizing the milling processing of the metal mirror, and the second electric push rod 1104 is used to adjust the milling position of the milling tool.

The multi-layer structure of the second milling tool 1202 and the taper notch 1205 with different tapers at the bottom enable the device to process annular workpieces of different sizes. When the first milling tool 1201 rotates, the first limit block 1203 will drive the second milling tools 1202 at other locations to rotate synchronously, thereby performing mirror processing on the workpiece surface. When it is necessary to switch the processing mode, turn off the second motor 1101 on the driving assembly 11. The second motor 1101 can use an electromagnetic brake motor to keep the milling assembly 12 stationary. By abutting different surfaces of the fixing assembly 13 against the outer surface of the workpiece, it can adapt to the use of different parts, such as Figure 6 As shown, by aligning the two protrusions 1303 with the recessed positions of the installation groove 1301 and aligning the installation rod 1302 with the center position of the installation groove 1301, the clamping block 1304 is installed forward or reversely, so that the device can switch different clamping surfaces on the clamping block 1304 as needed, and the first motor 4 on the first support seat 3 drives the support plate 5 to rotate, so that the workpiece rotates for milling processing. Fig. 9 and Fig.10 As shown, when the connecting shell 14 drives the magnetic metal damping plate 20 and the connecting disk 19 to rotate by rotating the block 18, the magnetic block 17 can remain stationary, and the initial height of the magnetic block 17 is adjusted by the third electric push rod 15, thereby adjusting the adsorption force of the magnetic metal damping plate 20 on the metal workpiece, and the thin-walled parts can be mirror-finished subsequently.

The position of the magnetic metal damping plate (20) is adjusted by extending the third electric push rod (15), thereby changing the initial position of the workpiece and the resistance of the contact surface at the bottom of the workpiece; S2: The initial height of the support block (23) is adjusted by the first electric push rod (10), the driving assembly (11) is used to drive the milling assembly (12) to rotate and change the height of the milling assembly (12), the milling assembly (12) can perform mirror processing on the inner wall edge of the annular workpiece during milling, and the multi-layer structure of the milling assembly (12) can process annular workpieces of different sizes; S3: When it is necessary to switch the processing mode, the driving component (11) is turned off to keep the milling component (12) stationary, and different surfaces of the fixing component (13) are brought into contact with the outer surface of the workpiece to adapt to the use of different parts. The first motor (4) on the first support seat (3) drives the support plate (5) to rotate, thereby rotating the workpiece for milling processing.
