Description

Technical Field

[0001] This utility model relates to the field of ring polisher structure technology, and in particular to an asphalt disc ring polisher and its surface shape control mechanism. Background Technology

[0002] Ring polishing machines are widely used in the processing of various brittle and hard materials due to their extremely high machining accuracy and excellent global surface flatness. Large-diameter, high-precision optical components, after milling, grinding, and rough polishing, are typically processed using ring polishing machines, or ring polishing machines combined with CNC small grinding heads, ion beams, or magnetorheological equipment, to produce ultra-high precision optical elements. Therefore, ring polishing machines are an indispensable and important step in the precision machining process.

[0003] When polishing workpieces using an asphalt disc ring polisher, the principle of "low in, high out" is usually adopted. By frequently adjusting the position of the calibration disc, the asphalt ring of the ring polisher is trimmed to a near-perfect plane. The high-precision surface shape of the workpiece is obtained by replicating this plane.

[0004] However, due to the properties of asphalt, the surface profile of the asphalt disc is quickly destroyed when workpieces of different sizes, weights, and initial surface profiles are input. To determine the real-time surface profile of the asphalt disc, it is necessary to periodically check the surface profile of the workpiece during polishing to obtain feedback on the asphalt disc's profile. Then, using the principle of "low in, high out," the position of the calibration disc is adjusted to correct the high-precision surface profile of the asphalt disc, thereby producing a workpiece with a high-precision surface profile. When the workpiece is relatively small, stopping the machine and removing the workpiece is relatively simple. However, when the weight of a single workpiece reaches 10kg or more, the entire process of stopping the machine, removing the workpiece, cleaning, letting it stand for 30 minutes, and checking the surface profile of the workpiece becomes very time-consuming and labor-intensive, consuming a significant amount of processing time, and introducing many uncertainties and risks, such as workpiece damage or new scratches on the workpiece surface.

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] This utility model proposes a surface shape control mechanism for an asphalt disc ring polisher.

[0030] Reference Figures 1 to 3In this preferred embodiment, a surface shape control mechanism for an asphalt disc polisher includes a support frame 1, a caliper 2, a control disc 3, an active nylon wheel 4, and a driven nylon wheel 5, wherein...

[0031] The support frame 1 is used to connect with the base 7 of the asphalt disc ring polisher. The top surface of the support frame 1 is detachably connected to the caliper 2. The active nylon wheel 4 and the driven nylon wheel 5 are both installed below the caliper 2 and can rotate relative to it. The control disc 3 is placed above the asphalt disc of the asphalt disc ring polisher. The side of the control disc 3 abuts against the active nylon wheel 4 and the driven nylon wheel 5. The material of the control disc 3 is the same as the workpiece to be processed on the asphalt disc ring polisher. The surface shape of the asphalt disc is fed back by detecting the surface shape of the control disc 3.

[0032] In this embodiment, refer to Figure 3 The control disc 3 has a disc-shaped structure. The diameter of the control disc 3 is 1 / 8 to 1 / 5 of the diameter of the asphalt disc. For example, a φ200 control disc 3 can be configured for a 1.6m diameter ring polisher, and a φ250 control disc 3 can be configured for a 2m diameter ring polisher, etc.

[0033] Specifically, the thickness of the control disc component 3 is 30mm~50mm. The thickness of the driving nylon wheel 4 and the driven nylon wheel 5 is 20mm~40mm thicker than that of the control disc component 3.

[0034] Specifically, a drive mechanism 6 is mounted on the caliper 2. The output shaft of the drive mechanism 6 is fixedly connected to the active nylon wheel 4 to drive its rotation. The drive mechanism 6 can be a motor, which is connected to an organic controller to control the rotation speed of the control disc 3 to match the rotation speed of the polishing disc, thereby enabling the control disc 3 to remove material evenly.

[0035] Furthermore, both the top surface of the support frame 1 and the caliper 2 are provided with oblong holes, through which fasteners pass to fix the support frame 1 and the caliper 2. By providing oblong holes, it is convenient to adjust the specific connection position of the caliper 2 on the support frame 1.

[0036] Combined with reference Figure 1 and Figure 3 This embodiment proposes a specific structure for a support frame 1: the support frame 1 includes a bottom crossbar 11, uprights 13 and a bottom connecting plate 12 respectively fixed to both sides of the bottom crossbar 11, and a top connecting plate 14 fixed to the top of the uprights 13. Both the bottom connecting plate 12 and the top connecting plate 14 are provided with oblong holes. The top connecting plate 14 and the bottom connecting plate 12 are arranged vertically. Fasteners pass through the oblong holes of the bottom connecting plate 12 to connect the support frame 1 to the base 7 of the ring shot machine.

[0037] The bottom connecting plate 12 has an oblong hole, which facilitates the adjustment of the installation height of the support frame 1 relative to the asphalt disc ring polisher.

[0038] The caliper 2 has mounting holes, and the shafts of both the driving nylon wheel 4 and the driven nylon wheel 5 are located inside the mounting holes.

[0039] The working process of the surface shape control mechanism of this asphalt disc ring polisher is as follows: Taking a 2m ring polisher as an example, the support frame 1 is installed and fixed on the base 7 of the equipment. The clamp 2 is installed on the support frame 1, and the drive mechanism 6, the active nylon wheel 4, and the driven nylon wheel 5 are installed on the clamp 2. The controller is connected to the drive mechanism 6 and the power supply, thus completing the installation of the surface shape control mechanism. The equipment is started under no-load, and the control disc 3 is placed above the asphalt disc, so that it abuts against the active nylon wheel 4 and the driven nylon wheel 5. Every 2 hours or so, the control disc 3 is removed from the disc, and the surface shape of the polished surface of the control disc 3 is measured by a corresponding measuring mechanism. Since the material of the control disc 3 is the same as that of the workpiece, when the asphalt disc polishes the workpiece, it will also polish the control disc 3 simultaneously. By measuring the surface shape of the polished surface, the real-time surface shape and surface shape change trend of the asphalt disc can be indirectly known. Similarly, after the workpiece to be processed is placed on the equipment station, the real-time surface shape of the asphalt plate and the workpiece can be known by measuring the surface shape of the control plate 3. The plate surface can be corrected by adjusting the position of the calibration plate, and finally the workpiece with the target surface shape can be obtained.

[0040] The surface shape control mechanism of the asphalt disc ring polisher proposed in this embodiment has the following beneficial effects:

[0041] 1. By measuring the surface profile of the control disc 3, which is easy to disassemble and install, the real-time surface profile and surface profile change trend of the asphalt disc can be indirectly obtained. It can also indirectly measure the surface profile of the workpiece above the asphalt disc, avoiding the problem of workpiece damage and new scratches on the workpiece surface caused by directly removing the workpiece to measure the surface profile, thus improving processing efficiency.

[0042] 2. By adjusting the position of the calibration disc, the high-precision surface profile of the asphalt disc can be corrected, thereby enabling the processing of workpieces with high-precision surface profiles;

[0043] 3. This surface-type control mechanism can be easily and conveniently installed on existing ring polishing machines. It is highly versatile, and its structure and operation are both very simple and convenient.

[0044] This utility model also proposes an asphalt disc ring polisher.

[0045] Reference Figure 4 In this preferred embodiment, an asphalt disc ring polisher includes a surface shape control mechanism, a base 7, and an asphalt disc located above the base 7. The specific structure and beneficial effects of the surface shape control mechanism are the same as those in the above embodiments, and will not be repeated here.

[0046] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
