Abstract

The utility model discloses a grinding wheel with high machining precision and stability, which comprises a support, a carriage mechanism and a grinding wheel mechanism. The carriage mechanism comprises a bottom plate and a sliding plate, the bottom plate is fixed on the inclined plane, and the sliding plate is slidably connected with the bottom plate; the grinding wheel mechanism is installed on the sliding plate through an installation base. When the sliding plate slides on the bottom plate, the sliding direction of the sliding plate is consistent with the inclination direction of the inclined face, and therefore the grinding wheel mechanism can be driven to move in the inclination direction of the inclined face. The inclination angle of the grinding wheel mechanism is the same as that of the inclined face, and when the sliding plate slides, the feeding direction of the grinding wheel mechanism is consistent with the axis direction of the grinding wheel mechanism. By means of the design mode, it can be ensured that the contact position of the grinding wheel and the grinding face of the glass plate cannot be changed after the grinding wheel mechanism is fed by the preset distance in the axis direction, and then it is ensured that the grinding wheel mechanism can still keep high and stable machining precision after a plurality of glass plates are continuously machined (the grinding wheel is abraded).

Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a grinding wheel with high and stable processing precision. Background Art

[0002] A glass edging machine is a glass processing equipment used for grinding the edges of glass sheets or plates. A common glass edging machine generally includes a grinding wheel (or grinding head) feeding mechanism, on which a driving mechanism, a grinding wheel mechanism, etc. are provided, and the edge of the glass is ground by the grinding wheel mechanism.

[0003] For example, the Chinese patent with the publication number CN220680307U discloses a grinding head feeding mechanism of a glass edging machine. The grinding head feeding mechanism of this glass edging machine has mechanisms such as a base, a sliding plate, a driving component, and a grinding head component. The above glass edging machine can realize the grinding of the glass edge, but there are also the following technical defects and deficiencies: Since the grinding head will wear during continuous processing, when the grinding head continuously processes multiple pieces of glass from an inclined direction, the grinding head needs to feed forward a displacement for distance compensation according to its wear amount. However, the feeding direction of the carriage is horizontal and inconsistent with the direction of the inclined grinding head. Therefore, after feeding horizontally for a certain distance, the contact position between the grinding head and the cutting surface of the subsequent glass plate changes (towards the center direction of the grinding head), resulting in a change in the rotational linear velocity of the grinding head for the subsequent glass plate, affecting the processing precision of the glass plate.

[0004] Therefore, the prior art urgently needs to invent a grinding wheel mechanism that can still maintain high and stable processing precision after processing multiple glass plates obliquely. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a grinding wheel with high and stable processing precision. This grinding wheel can maintain the position with the cutting surface of the glass plate unchanged when processing multiple glass plates obliquely, thus having the characteristic of high processing precision.

[0006] The technical solution adopted by the utility model to solve its problems is as follows:

[0007] A grinding wheel with high and stable processing precision, which includes:

[0008] A support, on which an inclined surface is provided;

[0009] A carriage mechanism, which includes a bottom plate and a sliding plate. The bottom plate is fixed on the inclined surface, and the sliding plate is slidably connected to the bottom plate;

[0010] A grinding wheel mechanism, an installation seat is fixedly provided on the sliding plate, and the grinding wheel mechanism is provided on the installation seat;

[0011] Among them, the inclination angle of the grinding wheel mechanism is the same as that of the inclined surface, so that when the sliding plate slides, the feeding direction of the grinding wheel mechanism is consistent with the axis direction of the grinding wheel mechanism.

[0012] In a preferred embodiment of the present utility model, a technical solution regarding the transmission mode of the grinding wheel mechanism is provided.

[0013] In this preferred embodiment, a first driving mechanism is further provided on the mounting seat. The grinding wheel mechanism includes a grinding wheel, and the first driving mechanism is used to drive the grinding wheel to rotate.

[0014] Furthermore, a first transmission wheel is provided on the output shaft of the first driving mechanism, and a second transmission wheel is provided at the input end of the grinding wheel mechanism. The first transmission wheel and the second transmission wheel are connected by a transmission belt.

[0015] Furthermore, the transmission belt is a belt.

[0016] Furthermore, an upper cover is detachably provided on the mounting seat, and a receiving space is formed therebetween for receiving the first transmission wheel, the second transmission wheel, and the transmission belt.

[0017] In another preferred embodiment of the present utility model, a technical solution regarding the specific structural design of the carriage mechanism is provided.

[0018] In this preferred embodiment, the carriage mechanism further includes a guide rail, the guide rail is disposed between the bottom plate and the sliding plate, and the bottom plate and the sliding plate are slidably connected through the guide rail.

[0019] Furthermore, the carriage mechanism further includes a second driving mechanism, and the second driving mechanism is used to drive the sliding plate to slide relative to the bottom plate, thereby driving the grinding wheel mechanism to move.

[0020] In another preferred embodiment of the present utility model, a technical solution regarding the specific structural design of the support is provided.

[0021] In this preferred embodiment, the support includes a horizontal plate, a vertical plate, and an inclined plate. The horizontal plate and the vertical plate are arranged perpendicular to each other. The inclined plate is respectively connected to both ends of the horizontal plate and the vertical plate, so that the inclined plate is inclined. The inclined surface is provided on the inclined plate.

[0022] Furthermore, the support further includes a reinforcing plate, and the reinforcing plate is disposed between the horizontal plate, the vertical plate, and the inclined plate for supporting the inclined plate.

[0023] Furthermore, the inclination angle of the inclined surface is 45°.

[0024] In summary, compared with the prior art, the grinding wheel with high and stable processing precision provided by the present utility model has at least the following technical effects:

[0025] 1) The grinding wheel of the present utility model includes a support, a carriage mechanism, and a grinding wheel mechanism. The carriage mechanism is arranged on the inclined surface of the support. The carriage mechanism includes a bottom plate and a sliding plate that are slidably connected to each other. The grinding wheel mechanism is arranged on the sliding plate through a mounting seat. When the sliding plate slides on the bottom plate, its sliding direction is the same as the inclination direction of the inclined surface, thereby driving the grinding wheel mechanism to move along the inclination direction of the inclined surface. Therefore, by setting the inclination angle of the grinding wheel mechanism to be the same as the inclination angle of the inclined surface, the present utility model can ensure that when the sliding plate slides, the feed stroke direction of the grinding wheel mechanism is consistent with the axis direction of the grinding wheel mechanism. Through the above design method, no matter how long the grinding wheel mechanism feeds along the axis direction, the contact position between the grinding wheel and the cutting surface of the glass plate in the subsequent process will not change, thereby ensuring that the grinding wheel mechanism can still maintain high and stable processing precision when continuously processing multiple glass plates.

[0026] 2) The grinding wheel of the present utility model further includes a first driving mechanism. The output shaft of the first driving mechanism is provided with a first transmission wheel, and the input end of the grinding wheel mechanism is provided with a second transmission wheel. The two transmission wheels are connected by a transmission belt (preferably a belt), so as to realize the rotation of the grinding wheel through belt transmission. Compared with the transmission method in which the output shaft of the motor is directly connected to the grinding wheel mechanism, the belt transmission method of the present utility model has the characteristics of smooth transmission and shock mitigation. When the grinding wheel encounters an obstacle or is overloaded during glass grinding, the belt will slip on the belt pulley, thereby preventing damage to the machine parts. Moreover, the design method of belt transmission is convenient for the operator to disassemble, assemble and maintain, and the use cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Embodiment 1

[0038] See Figure 1 and Figure 2 As shown in [relevant figures], in the first embodiment of the present invention, the grinding wheel with high processing precision and stability includes a support 1 and a carriage mechanism. Among them, the support 1 is provided with an inclined surface, and the inclined surface is inclined relative to the horizontal plane or the plane where the glass plate is located during the processing of the glass edging machine. The carriage mechanism includes a bottom plate 2 and a slide plate 3. The bottom plate 2 is fixed on the inclined surface of the support 1, and the slide plate 3 is slidably connected to the bottom plate 2. Different from the horizontal sliding setting method of the slide plate 3 in the prior art, through the inclined surface setting on the support 1, the slide plate 3 of the present invention can slide on the bottom plate 2 in an inclined direction, and the inclination angle of the sliding direction of the slide plate 3 is equal to the inclination angle of the inclined surface of the support 1.

[0039] The grinding wheel with high processing precision and stability further includes a mounting seat 4 and a grinding wheel mechanism 5. The mounting seat 4 is fixed on the slide plate 3, and the grinding wheel mechanism 5 is arranged on the mounting seat 4. Among them, the mounting seat 4 serves as a support structure to mount the grinding wheel mechanism 5 on the slide plate 3. When the slide plate 3 slides in an inclined direction, it can drive the grinding wheel mechanism 5 to slide in the same direction to complete the feed stroke of the grinding wheel mechanism 5. The grinding wheel mechanism 5 is used to complete the grinding operation on the edge of the glass plate 10 on the glass edging machine.

[0040] See Figure 4 As shown, in the solution of the prior art, when the grinding wheel mechanism 5 continuously processes multiple glass plates 10 from an inclined direction, the grinding wheel mechanism 5 needs to feed forward a displacement for distance compensation according to the wear amount of its grinding wheel. The feeding direction of the carriage mechanism driving the grinding wheel mechanism 5 is the horizontal direction, which is inconsistent with the axis direction of the inclined grinding wheel mechanism 5. Therefore, after feeding a certain distance horizontally, the contact position between the grinding wheel mechanism 5 and the cutting surface of the glass plate 10 in the subsequent process changes (from Figure 4 It can be seen that after the grinding wheel mechanism 5 moves horizontally, the contact position between the two will approach the center direction of the grinding wheel), resulting in a change in the rotational linear velocity of the grinding wheel mechanism 5 relative to the subsequent glass plate 10, thereby affecting the processing accuracy of the glass plate.

[0041] See Figure 5 As shown, in the technical solution of this embodiment, the inclination angle of the grinding wheel mechanism 5 is the same as the inclination angle of the upper inclined surface of the support 1. Therefore, when the slide plate 3 slides along the inclined direction, it can drive the grinding wheel mechanism 5 to slide in the same direction, so that the feeding stroke direction of the grinding wheel mechanism 5 is consistent with the axis direction of the grinding wheel mechanism 5. Through the above design method, no matter how long the grinding wheel mechanism 5 feeds along the axis direction, the contact position between the grinding wheel mechanism 5 and the cutting surface of the glass plate 10 in the subsequent process will not change. Furthermore, when ensuring that the grinding wheel mechanism 5 continuously processes multiple glass plates 10 in the inclined direction, it can still maintain a high and stable processing accuracy.

[0042] Embodiment 2

[0043] In the second embodiment of the present invention, on the basis of the first embodiment, a technical solution regarding the transmission method of the grinding wheel mechanism 5 is provided.

[0044] See Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, a first driving mechanism 6 is further provided on the mounting seat 4. The grinding wheel mechanism 5 includes a grinding wheel 51, and the first driving mechanism 6 is used to drive the grinding wheel 51 to rotate. During processing, the grinding wheel 51 is used to directly contact the edge of the glass plate 10, thereby completing the grinding operation on the glass plate 10. The first driving mechanism 6 can preferably adopt a servo motor, and the servo motor is used to drive the grinding wheel 51 to rotate, thereby completing the edge grinding operation.

[0045] See Figure 3As shown, in a preferred solution of this embodiment, the first driving mechanism 6 is provided with an output shaft, on which a first transmission wheel 61 is provided. The grinding wheel mechanism is provided with an input end, on which a second transmission wheel 52 is provided. The first transmission wheel 61 and the second transmission wheel 52 are connected by a transmission belt 8. Among them, the first transmission wheel 61 is the driving wheel and the second transmission wheel 52 is the driven wheel. The transmission belt 8 is sleeved on the two transmission wheels. The specific transmission process is as follows: when the first driving mechanism 6 is started, its output shaft drives the first transmission wheel 61 to rotate, and then drives the second transmission wheel 52 to rotate through the transmission belt 8, and finally drives the grinding wheel 52 on the grinding wheel mechanism 5 to rotate. Through this structural design method, the long-distance transmission effect between the first driving mechanism 6 and the grinding wheel mechanism 5 can be achieved. Compared with setting the first driving mechanism 6 and the grinding wheel mechanism 5 together, the structural design method of this embodiment is beneficial to the spatial distribution setting of each component on the grinding wheel and is convenient for the operator to disassemble, install and maintain.

[0046] Furthermore, the transmission belt 8 can adopt a belt. At this time, the first transmission wheel 61 and the second transmission wheel 52 adopt belt pulleys. The belt is sleeved on the two belt pulleys, and the long-distance transmission between the first driving mechanism 6 and the grinding wheel mechanism 5 can be completed. Specifically, compared with the transmission method of directly connecting the motor output shaft and the grinding wheel mechanism 5, the belt transmission method in this embodiment has the characteristics of stable transmission and shock mitigation. When the grinding wheel mechanism 5 encounters an obstacle or is overloaded during glass grinding, the belt will slip on the belt pulley, thus preventing the machine parts from being damaged. And the design method of belt transmission is convenient for the operator to disassemble, install and maintain, reducing the use and maintenance costs.

[0047] See Figure 2 As shown, in another preferred solution of this embodiment, an upper cover 9 is detachably provided on the mounting base 4. An accommodation space is formed between the mounting base 4 and the upper cover 9, and this accommodation space is used to accommodate the first transmission wheel 61, the second transmission wheel 52 and the transmission belt 8. Among them, when the upper cover 9 is installed on the mounting base 4, it can play a role in preventing dust, water and other impurities from entering the first transmission wheel 61, the second transmission wheel 52 and other components in the accommodation space, reducing the influence of the external environment on the above components. When a component on the mounting base 4 fails or needs regular maintenance, the operator can directly remove the upper cover 9 and perform operations such as disassembly, installation and repair on the components inside, and the operation is simple.

[0048] Embodiment 3

[0049] In the third embodiment of the present invention, on the basis of the first embodiment, a technical solution for the specific structural design of the carriage mechanism is provided.

[0050] See Figure 1 and Figure 2As shown, in the technical solution of this embodiment, the carriage mechanism further includes a guide rail (not shown in the figure), which is disposed between the base plate 2 and the slide plate 3. The base plate 2 and the slide plate 3 are slidably connected through the guide rail. Specifically, the number of guide rails is at least two. One guide rail is fixedly connected to the base plate 2, and the other is fixedly connected to the slide plate 3. The two guide rails are slidably connected to each other, so as to realize the tilting slide of the slide plate 3 on the base plate 2. Through the design method of connecting with the guide rail, the carriage mechanism can arrange multiple guide rails in the groove space between the base plate 2 and the slide plate 3, thereby effectively preventing impurities such as dust and liquid from entering the guide rail, reducing the influence of the external environment on the guide rail, and ensuring the stable operation of the carriage mechanism. Preferably, the guide rail can adopt a crossed roller guide rail.

[0051] See Figure 1 and Figure 2 As shown, in a preferred solution of this embodiment, the carriage mechanism further includes a second driving mechanism 7. The second driving mechanism 7 is used to drive the slide plate 3 to slide relative to the base plate 2, and then drive the grinding wheel mechanism 5 to move. Specifically, the second driving mechanism 7 can adopt a ball screw mechanism or a cylinder and other driving mechanisms, and its output end drives the slide plate 3 to slide along the inclined direction, and then drives the grinding wheel mechanism 5 to feed and move along its axis direction.

[0052] Embodiment 4

[0053] In the fourth embodiment of the present invention, on the basis of the first embodiment, a technical solution for the specific structural design of the support 1 is provided.

[0054] See Figure 2 As shown, in the technical solution of this embodiment, the support 1 includes a horizontal plate 11, a vertical plate 12 and an inclined plate 13. The horizontal plate 11 and the vertical plate 12 are arranged perpendicular to each other. The inclined plate 13 is respectively connected to the two ends of the horizontal plate 11 and the vertical plate 12, so that the inclined plate 13 is inclined. There is an inclined surface on the inclined plate 13. Among them, the horizontally and vertically arranged horizontal plate 11 and vertical plate 12 form an L-shaped plate structure. After the inclined plate 13 is respectively connected to the two ends of the horizontal plate 11 and the vertical plate 12, it can be inclined relative to the horizontal plane or the plane where the glass edging machine is located during processing, so as to realize the feed stroke of the carriage mechanism in the inclined direction. Moreover, the horizontal plate 11 and the vertical plate 12 respectively support the inclined plate 13 in the horizontal and vertical directions, and the triangular structure formed by the three plates has high structural stability.

[0055] See Figure 2As shown, in a preferred solution of this embodiment, the support 1 further includes a reinforcing plate 14, and the reinforcing plate 14 is disposed between the horizontal plate 11, the vertical plate 12 and the inclined plate 13. As described above, the horizontal plate 11, the vertical plate 12 and the inclined plate 13 form a triangular structure. By providing the reinforcing plate 14 between the three, the stability of the triangular structure can be further improved, thereby enhancing the structural support for the inclined plate 13 and ensuring the smooth sliding of the carriage mechanism on the inclined surface of the inclined plate 13.

[0056] Preferably, in this embodiment, the inclination angle of the inclined surface on the inclined plate 13 can be set to 45°. Through this angle design, the grinding area of the grinding wheel mechanism 5 on the edge of the glass plate 10 can be increased, and at the same time, the processing accuracy of the grinding wheel mechanism 5 on the glass plate 10 can be further improved.

[0057] In summary, by inclining the carriage mechanism and keeping the feeding direction of the grinding wheel mechanism 5 consistent with the axis direction of the grinding wheel mechanism 5 when the carriage mechanism slides, the present invention can ensure that after the grinding wheel mechanism 5 feeds a preset distance along the axis direction, the contact position between the grinding wheel 51 and the cutting surface of the glass plate 10 in the subsequent process will not change, thereby ensuring that the grinding wheel mechanism 5 can still maintain a high and stable processing accuracy when continuously processing multiple glass plates 10. Moreover, the present invention realizes the rotation of the grinding wheel through a belt drive. Compared with the drive method of directly connecting the motor output shaft and the grinding wheel mechanism, the belt drive method has the characteristics of smooth transmission and shock mitigation. When the grinding wheel 51 encounters an obstacle or is overloaded during glass grinding, the belt will slip on the pulley, thereby preventing damage to the machine parts. And the design method of the belt drive is convenient for the operator to disassemble, assemble and maintain, and has a low use cost.

[0058] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
