Description

Technical Field

[0001] This invention relates to the field of glass grinding technology, specifically to a triple composite grinding disc and a glass straight edge grinding machine. Background Technology

[0002] A glass straight edge grinding machine is used to chamfer the bottom and end face edges of cut glass blanks, creating straight planes to meet dimensional and surface quality requirements. This is commonly known as straight edge (or trapezoidal edge or FA edge) processing. Existing glass straight edge grinding machines utilize diamond cup wheels for processing. The diamond cup wheel consists of a diamond grinding ring connected to the base material, with the end face being the main grinding surface. An optimized solution involves manufacturing various water channels and chip / discharge grooves on the diamond grinding ring to improve the grinding wheel's performance. Cup wheel processing typically only processes one plane.

[0003] Glass straight edge processing involves grinding the bottom edge of the glass with a cup-shaped wheel and chamfering the edges of both ends. Each grinding position requires at least one cup-shaped grinding wheel. The complete glass grinding process includes: rough grinding, fine grinding, precision grinding, polishing, and varnishing. Usually, each process requires at least one cup-shaped grinding wheel. Difficult processes may require multiple grinding wheels with the same function to complete. Current straight edge grinding machines typically use one grinding wheel each for rough grinding, fine grinding, and precision grinding for bottom edge processing, 1-3 grinding wheels for polishing, and one grinding wheel for varnishing. For chamfering, they usually only perform fine grinding and polishing, each using one grinding wheel; that is, two grinding wheels are used for each chamfer. The total number of grinding wheels in the machine is usually 9-11. Although the chamfer width is smaller (i.e., the amount of material to be ground is smaller), the grinding quality of the chamfer is much worse than that of the bottom edge because only two grinding wheels are used for fine grinding and polishing on each chamfer edge. This affects the overall quality of glass edging. Furthermore, since the chamfer forming process uses a fine grinding cup-shaped wheel, the grinding ability of which is weak, the overall grinding efficiency of the machine is also limited by the chamfer grinding capability.

[0004] With the increasing demands for feed speed, surface roughness, and gloss in glass processing, the existing straight edge grinding machine configurations and processing parameters are no longer sufficient to meet these requirements.

[0005] Traditional techniques offer a solution for rough grinding of chamfered areas: using a single wheel in two positions to achieve the initial rough grinding of the chamfer area. This significantly reduces the pressure of the initial grinding and allows the grinding wheel at the chamfer area to develop towards fine grinding, which in turn facilitates the processing of the polishing wheel, thereby improving the grinding quality of the chamfer. However, despite this, the function and number of grinding wheels at the chamfer area are still insufficient compared to the bottom edge. Therefore, the grinding quality of the chamfer is still lower than that of the bottom edge, resulting in inconsistencies in the quality of the glass grinding areas and affecting the appearance. Summary of the Invention

[0006] This invention provides a triple-layer composite grinding disc and a glass straight-edge grinding machine, aiming to solve the above-mentioned technical problems in the prior art. The technical solution of this invention is as follows:

[0007] A triple composite grinding disc includes a polishing ring, a fine grinding ring, a precision grinding ring, and a base. The polishing ring, the precision grinding ring, and the fine grinding ring are coaxially fixedly mounted on the base from the inside to the outside. The polishing ring is composed of multiple wheel pieces.

[0008] One end of the base is provided with an internal cooling cavity, and one end face of the base is provided with an internal cooling water inlet communicating with the internal cooling cavity. The base is also provided with multiple openings communicating with the internal cooling cavity, and multiple openings and the polishing wheel ring form multiple internal cooling water channels. The side wall of the base is provided with an annular external cooling water channel, and its side wall is also provided with at least one external cooling water inlet communicating with the external cooling water channel.

[0009] The beneficial effects of this invention are: during the processing, the chamfer of the glass can be processed by three steps: fine grinding, fine grinding and polishing, through a fine grinding ring, a fine grinding ring and a polishing wheel ring, resulting in high processing efficiency and better processing quality;

[0010] In addition, the present invention adopts a dual-circuit water supply internal cooling method, which provides efficient cooling and rapid chip removal, greatly improving the processing efficiency and quality of the triple grinding disc and reducing processing costs.

[0011] The invention has a simple structure and reasonable design. Since the three-layer composite grinding disc can complete three processes in one position and the internal components are seamlessly connected, the trouble of tool setting is greatly reduced and unnecessary wear is reduced. It is especially suitable for rapid feed and high-precision machining, and the machining efficiency is greatly improved.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the substrate includes a substrate one, a pressure plate, and a connecting plate. The connecting plate is fixedly installed at one end of the polishing wheel ring, and the substrate one is fixedly sleeved outside the connecting plate. The fine grinding ring and the precision grinding ring are located at one end of the substrate one. The pressure plate is installed inside the polishing wheel ring and is fixedly connected to the connecting plate to press the polishing wheel ring tightly.

[0014] The internal cooling cavity is disposed within the pressure plate, and the internal cooling water inlet is disposed at the center of the pressure plate. Multiple openings are respectively disposed on the side wall of the pressure plate. The gap between the base and the connecting plate forms the external cooling water channel. A rear cooling water supply is installed on the other end of the base. The rear cooling water supply has an external cooling cavity inside. Each external cooling water inlet is disposed on the rear cooling water supply and communicates with the external cooling cavity. One end of the rear cooling water supply has an annular outlet, and the other end of the base has an annular inlet. The annular inlet communicates with the annular outlet.

[0015] The advantages of adopting the above-mentioned further solution are that the structure is simple, the design of the substrate, pressure plate and connecting plate is reasonable, which can realize the connection between them without affecting the processing of glass by the polishing wheel ring, fine grinding ring and fine grinding ring, and the processing is convenient.

[0016] In addition, the reasonable route design of the internal and external cooling water channels, efficient cooling and rapid chip removal greatly improve the processing efficiency and quality of the triple grinding disc, and reduce processing costs.

[0017] Furthermore, the substrate also includes a second substrate, which is sleeved on one end of the polishing wheel ring and fixedly connected to the first substrate; the fine grinding ring and the precision grinding ring are respectively fixedly connected to the second substrate.

[0018] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable, and the stability of the installation of each component can be increased through the second base.

[0019] Furthermore, the inner wall of the polishing wheel ring is provided with an annular boss, and the pressure plate presses the annular boss tightly.

[0020] The advantages of adopting the above-mentioned further solution are that the structure is simple, the design is reasonable, and the special structure of the pressure plate and the polishing wheel ring itself is used to fix the polishing wheel ring, making assembly convenient.

[0021] Furthermore, the pressure plate has an annular plate structure, the multiple wheel pieces are distributed in a circle, and the outer sides of two adjacent wheel pieces are attached together while the inner sides are separated to form a front water channel that is connected to the inner cooling water channel.

[0022] The beneficial effects of adopting the above-mentioned further solution are that during the processing, the front cooling water enters the area between the polishing wheel ring and the pressure plate from the internal cooling water inlet at the center of the pressure plate. Then, the centrifugal force of the entire grinding disc during rotation is used to throw the cooling water out through the internal cooling water channel from multiple front water channels to cool the polishing wheel ring and the workpiece, thereby preventing the polishing wheel ring from getting too hot and ensuring the quality of glass processing. The multiple wheel pieces are spliced ​​together, and the wheel pieces deform under the force during operation, forming gaps, which further enhances the effect of internal cooling water supply.

[0023] The solution has a simple structure and reasonable design. It utilizes the special structure of the pressure plate to form a convergence of cooling water, reduce the waste of cooling water splashing, and prevent the cooling water from being atomized by the airflow. Then, through the set internal cooling water channel and the front water channel, the polishing wheel ring and the workpiece are cooled, resulting in a better cooling effect.

[0024] Furthermore, it also includes a rotating shaft located at the end of the connecting plate away from the polishing wheel ring. The rotating shaft is coaxial with the polishing wheel ring, and one end of the rotating shaft is fixedly connected to the center of the connecting plate. The rotating shaft can rotate around its own axis. The rear cooling water supply unit is sleeved on the rotating shaft.

[0025] The advantage of adopting the above-mentioned further solution is that during processing, the other end of the rotating shaft is fixedly connected to the drive component of the machine tool, such as a motor, and the rotating shaft is driven to rotate by the motor, which in turn drives the entire grinding disc to rotate, so as to process the glass.

[0026] Furthermore, the fine grinding ring and the precision grinding ring are respectively provided with a rear water channel assembly that communicates with the external cooling water channel.

[0027] The beneficial effect of adopting the above-mentioned further scheme is that during the processing, cooling water enters the external cooling water channel and the rear water tank group sequentially from the inlet to form an internal cooling water supply method to cool the fine grinding ring, the precision grinding ring and the workpiece. The structure is simple, the design is reasonable and the cooling effect is better.

[0028] Furthermore, each of the rear water channel groups includes multiple rear water channels, which are evenly distributed circumferentially on the fine grinding ring or the precision grinding ring and penetrate axially. The inner sides of the multiple rear water channels on the fine grinding ring are open and the outer sides are closed. The inner and outer sides of a portion of the multiple rear water channels on the precision grinding ring are open, and they correspond one-to-one with and communicate with the multiple rear water channels on the fine grinding ring. The inner sides of the remaining portion of the rear water channels are open and the outer sides are closed.

[0029] The beneficial effect of adopting the above-mentioned further solution is that during the processing, cooling water enters the external cooling water channel and the rear water tank sequentially from the inlet to cool the fine grinding ring, the precision grinding ring and the workpiece. The structure is simple, the design is reasonable and the cooling effect is better.

[0030] In addition, the multiple rear water channels on the fine grinding ring and the precision grinding ring are reasonably designed to ensure that all parts of the fine grinding ring and the precision grinding ring are cooled, further enhancing the effect of internal cooling water supply and resulting in better cooling effect.

[0031] Furthermore, the fine grinding ring and / or the precision grinding ring are resin rings.

[0032] The beneficial effect of adopting the above-mentioned further solution is that the resin ring bonding strength is high, which is suitable for pre-polishing grinding and lays the foundation for high-quality polishing.

[0033] The present invention also relates to a glass straight edge grinding machine, comprising the triple composite grinding disc as described above.

[0034] The beneficial effect of adopting the above-mentioned further solution is that the present invention provides a glass straight edge grinding machine. The glass straight edge grinding machine has a simple structure and reasonable design. The three-layer composite grinding disc can complete three processes at one time, and the internal components are seamlessly connected, which greatly reduces the trouble of tool setting and reduces unnecessary wear. It is especially suitable for rapid feeding and high-precision processing, and the processing efficiency is greatly improved. Attached Figure Description

The processing efficiency is high and the processing quality is good.

[0051] In addition, the present invention adopts a dual-circuit water supply internal cooling method, which provides efficient cooling and rapid chip removal, greatly improving the processing efficiency and quality of the triple grinding disc and reducing processing costs.

[0052] Preferably, in this embodiment, the above-mentioned fine grinding ring 2 uses a resin binder, and the abrasive is diamond with a particle size range of 400#-150#, that is, a particle diameter range of 0.034-0.09mm.

[0053] In addition, the above-mentioned fine grinding ring 3 uses a resin binder and diamond as the abrasive, with a particle size range of 800#-600#, that is, a particle diameter range of 0.002-0.028mm.

[0054] Moreover, the aforementioned polishing wheel ring 1 uses a polyurethane binder and silicon carbide or aluminum oxide as the abrasive.

[0055] In the above scheme, the polishing wheel ring 1, the fine grinding ring 3 and the fine grinding ring 2 can also be arranged in reverse order of fine grinding, fine grinding and polishing, that is, the polishing wheel ring 1, the fine grinding ring 3 and the fine grinding ring 2 are arranged from the outside to the inside, but in this case, the glass grinding starts from the inner diameter part of the grinding disc.

[0056] Preferably, in this embodiment, there are multiple external cooling water inlets 13, and the multiple external cooling water inlets 13 are evenly spaced along the circumference of the shell.

The connecting plate 6 is fixedly installed at one end of the polishing wheel ring 1, and the substrate 4 is fixedly sleeved on the outside of the connecting plate 6. The fine grinding ring 2 and the high-precision grinding ring 3 are located at one end of the substrate 4. The pressure plate 7 is installed inside the polishing wheel ring 1 and is fixedly connected to the connecting plate 6 to press the polishing wheel ring 1 tightly.

[0060] The internal cooling cavity is disposed within the pressure plate 7, and the internal cooling water inlet 15 is disposed at the center of the pressure plate 7. Multiple openings are respectively disposed on the side wall of the pressure plate 7. The gap between the base 4 and the connecting plate 6 forms the external cooling water channel 10. A rear cooling water supply unit 12 is installed on the other end of the base 4. The rear cooling water supply unit 12 is provided with an external cooling cavity. Each external cooling water inlet 13 is disposed on the rear cooling water supply unit 12 and communicates with the external cooling cavity. One end of the rear cooling water supply unit 12 is provided with an annular outlet, and the other end of the base 4 is provided with an annular inlet. The annular inlet communicates with the annular outlet.

[0061] The structure of this scheme is simple, and the design of the base 4, pressure plate 7 and connecting plate 6 is reasonable. It can achieve the connection between them without affecting the processing of glass by the polishing wheel ring 1, fine grinding ring 2 and fine grinding ring 3, which is convenient for processing.

[0062] In addition, the internal and external cooling water channels are rationally designed, which enables efficient cooling and rapid chip removal, greatly improving the processing efficiency and quality of the triple grinding disc and reducing processing costs.

[0063] Preferably, in this embodiment, the substrate 4 and the connecting plate 6 are respectively annular structures, which facilitates the installation of the polishing wheel ring 1, the fine grinding ring 2 and the precision grinding ring 3.

[0064] In addition, a protrusion is provided at the center of the connecting plate 6. The protrusion extends into the polishing ring 1 and fits against the inner wall of the polishing ring 1. The design is reasonable and ensures the stability of the polishing ring 1 during installation.
