Description

Technical Field

[0001] The present invention relates to the technical field of grinding and polishing, and in particular to a grinding machine and a grinding system. Background Art

[0002] With the increasing use of stone products, surface processing has evolved from basic two-dimensional to three-dimensional processing. Spherical and cylindrical stone processing is the most common three-dimensional stone processing method, while grinding and polishing is the most common stone surface processing method and is usually the last step in stone surface processing.

[0003] Existing stone grinding and polishing usually adopts manual grinding or shaped wheel polishing. Manual grinding means that the stone product is fixed on the workbench to rotate or remain stationary, and the grinding head assembly is manually operated to contact the stone product for grinding and polishing. When the hardness of the stone is high, manual grinding is generally adopted for grinding and polishing. However, when the stone column material is defective, there are dark stone lines or the stone column is slender, it is easy to break. The processing is highly dangerous, and the size of the processed cylinder is not accurate and the error is large. When the hardness of the stone is relatively low, shaped wheel polishing is generally adopted for processing. However, the shaped wheel polishing cylinder cannot move and repair the grinding wheel, and the degree of grinding wheel wear varies, resulting in unsatisfactory surface finish and the presence of tip marks. It is expensive and has a slow processing speed. It is only suitable for grinding products with high production and single variety. In addition, the existing grinding and polishing methods have the defects of hard collision between the grinding head and the stone product, damage to the grinding head or inadequate grinding.

[0043] An embodiment of one aspect of the present invention, in combination with Figure 1As shown, a grinding machine is provided, including a lateral moving component 1, a longitudinal moving component 2, a grinding head component 3, a grinding head longitudinal adjustment and swing component 4 and a pneumatic component 5. The longitudinal moving component 2 is arranged on the lateral moving component 1, and the grinding head longitudinal adjustment and swing component 4 is slidably installed on the longitudinal moving component 2 and connected to the grinding head component 3 to control the swing of the grinding head component 3; the pneumatic component 5 is rotatably connected to the grinding head longitudinal adjustment and swing component 4. By controlling the forward and backward, left and right movement and swing of the grinding head assembly 3 through the grinding head longitudinal adjustment and swing assembly 4, the movement trajectory of the grinding head in the manual polishing mode can be simulated, thereby reducing errors, improving processing accuracy, reducing labor intensity, and avoiding the operational risks existing in the manual polishing mode; at the same time, by rotating the pneumatic assembly 5 and the grinding head longitudinal adjustment and swing assembly 4, the upward and downward movement of the grinding head assembly 3 can be controlled, thereby improving the overall flexibility, buffering the impact force generated by the contact between the grinding head assembly 3 and the surface of the stone product, reducing the damage to the grinding head caused by the uneven surface of the stone, and ensuring that the grinding head assembly 3 is always in contact with the surface of the stone product, thereby improving the surface brightness of the stone product and enhancing the polishing effect, and is particularly suitable for polishing stone products such as special-shaped parts and large cylinders. According to an embodiment provided by the present invention, combined with Figure 1 and Figure 2 As shown, the grinding machine includes a transverse movement assembly 1, a longitudinal movement assembly 2, a grinding head assembly 3, a grinding head longitudinal adjustment and swing assembly 4, and a pneumatic assembly 5. The transverse movement assembly 1 controls the movement of the grinding machine in the Y-axis direction, while the longitudinal movement assembly 2 controls the movement of the grinding machine in the X-axis direction. The present invention, based on the existing transverse movement assembly 1 and longitudinal movement assembly 2, adds a grinding head longitudinal adjustment and swing assembly 4 to further control the movement of the grinding machine in the Z-axis direction and rotation about the A-axis, achieving forward and backward, left and right movement, and swing of the grinding head assembly 3. This simulates the movement of the grinding head assembly 3 in manual grinding operation mode, reduces manual operation, and improves labor efficiency. The Y-axis is the direction of the motor output shaft of the transverse movement assembly 1, the X-axis is the direction of the motor output shaft of the longitudinal movement assembly 2, the Z-axis is the direction of the motor output shaft of the longitudinal adjustment assembly 41, and the A-axis is the direction of the motor output shaft of the grinding head swing assembly 42.

[0044] According to an embodiment of the present invention, referring to Figure 2As shown, the transverse movement assembly 1 includes a base 11, a transverse movement motor 12, a transverse movement screw 13 and a transverse movement slider 14. The transverse movement motor 12 is fixed to one end of the base 11, and the output shaft of the transverse movement motor 12 is connected to the transverse movement screw 13. When working, it can drive the rotation of the transverse movement screw 13. At the same time, the transverse movement slider 14 is slidably connected to the transverse movement screw 13. The rotation of the transverse movement screw 13 is converted into movement of the transverse movement slider 14 in the Y-axis direction, thereby realizing the movement of the grinding head assembly 3 in the Y-axis direction. Optionally, a slot is opened on the base 11, and the transverse movement screw 13 is inserted into the slot of the base 11. The transverse movement slider 14 is slidably connected to the transverse movement screw 13, and the structure at both ends of the transverse movement slider 14 is adapted to the structure on both sides of the base 11, so that when the transverse movement slider 14 slides on the transverse movement screw 13, the bottom plate can guide and limit the transverse movement slider 14, thereby preventing the transverse movement slider 14 from flipping or detaching.

[0045] According to one embodiment of the present invention, the longitudinal moving assembly 2 is used to realize the movement of the grinding head assembly 3 in the X-axis direction. The longitudinal moving assembly 2 includes a longitudinal moving base plate 21, a longitudinal moving motor 22 and a longitudinal moving screw 23, wherein the longitudinal moving base plate 21 is fixed to the base 11, the longitudinal moving motor 22 is installed at one end of the longitudinal moving base plate 21, and the longitudinal moving screw 23 is connected to the output shaft of the longitudinal moving motor 22, which can drive the rotation of the longitudinal moving screw 23 during operation. Optionally, a slot is opened on the longitudinal moving base plate 21, and the longitudinal moving screw is inserted into the slot of the longitudinal moving base plate 21; optionally, the longitudinal moving base plate 21 can also be fixed to the transverse moving slider 14, and the longitudinal moving base plate 21 can be integrally formed with the transverse moving slider 14 to form a cross-shaped slider, and then the cross-shaped slider is slidably installed on the transverse moving screw to realize the movement of the cross-shaped slider as a whole along the transverse screw. Alternatively, they can be separately manufactured and then welded together. This application does not make specific limitations on this.

[0046] It can be understood that the transverse moving component 1 and the longitudinal moving component 2 are set according to the original program of the workpiece, and on this basis, the grinding head longitudinal adjustment and swing component 4 is added to control the movement of the grinding head component 3.

[0047] According to one embodiment of the present invention, referring to Figure 2As shown, the grinding head longitudinal adjustment and swing assembly 4 includes a longitudinal adjustment assembly 41 and a grinding head swing assembly 42. The longitudinal adjustment assembly 41 is used to control the movement of the grinding head assembly 3 in the Z-axis direction, and the grinding head swing assembly 42 is used to control the rotation of the grinding head assembly 3 along the A-axis, thereby swinging the grinding head assembly 3 and changing the angle during grinding. The longitudinal adjustment assembly 41 is slidably connected to the longitudinal movement assembly 2, and the grinding head swing assembly 42 is mounted and fixed to the longitudinal adjustment assembly 41. It moves with the movement of the longitudinal adjustment assembly 41. The grinding head swing assembly 42 is rotationally connected to the grinding head assembly 3 to control the rotation of the grinding head assembly 3.

[0048] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the longitudinal adjustment assembly 41 includes a longitudinal adjustment motor 411, a longitudinal adjustment screw 412, and a longitudinal adjustment support 413. The output shaft of the longitudinal adjustment motor 411 is connected to the longitudinal adjustment screw 412, and can drive the rotation of the longitudinal adjustment screw 412 during operation. The longitudinal adjustment support 413 is slidably mounted on the longitudinal movement screw 23, realizing a sliding connection between the longitudinal adjustment assembly 41 and the longitudinal movement assembly 2. The longitudinal movement motor 22 drives the rotation of the longitudinal movement screw 23, and the rotation of the longitudinal movement screw 23 is converted into movement of the longitudinal adjustment support 413 in the X-axis direction, realizing movement of the grinding head assembly 3. Optionally, a slot is formed in the longitudinal adjustment support 413, and the longitudinal adjustment screw 412 is inserted into the slot of the longitudinal adjustment support 413.

[0049] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the grinding head swing assembly 42 includes a lateral swing motor 421 and a reducer 422. One end of the reducer 422 is fixedly connected to the lateral swing motor 421, and the other end is fixedly connected to the grinding head assembly 3. The output shaft of the lateral swing motor 421 is at a certain angle to the axis of the grinding head assembly 3. The rotation of the lateral swing motor 421 can realize the swing of the grinding head assembly 3 within a certain range, change the working angle of the grinding head assembly 3 during grinding, simulate the swing of the grinding head assembly 3 under the manual polishing operation mode, and effectively improve the grinding effect.

[0050] It is understood that the reducer 422 is a relatively precise machine that matches the speed and transmits torque between the lateral swing motor 421 and the working motor of the grinding head assembly 3. The purpose of using the reducer 422 is to reduce the speed while increasing the output torque and reducing the load inertia. The output torque ratio can be calculated by multiplying the output torque of the lateral swing motor 421 by the reduction ratio of the reducer 422. According to actual use needs, the appropriate lateral swing motor 421 and reducer 422 can be selected to reasonably control the swing amplitude and swing speed of the grinding head assembly 3 to improve the grinding accuracy. Optionally, a gear reducer, worm reducer, or planetary gear reducer can be used as the reducer 422. For example, a worm reducer can be used, which has a certain self-locking function and can limit the swing amplitude of the grinding head assembly 3. Optionally, the reducer can also be a stepper reducer or a servo reducer. Servo reducers have higher precision and are conducive to improving the grinding accuracy of stone products. During the production process, the appropriate servo reducer can be selected to meet the precision requirements of the processing. Other specific use needs can also be selected. This application does not make specific restrictions on this.

[0051] According to one embodiment of the present invention, referring to Figure 3 As shown, the grinding head swing assembly 42 also includes a swing support 423 and a swing base 424, wherein the lateral swing motor 421 is fixed to the swing base 424, and the swing base 424 and the swing support 423 are rotatably connected. The swing base 424 can rotate to a certain extent around the swing support 423, thereby realizing the rotation of the lateral swing motor 421 on the swing base 424, and further realizing the upward and downward movement of the grinding head assembly 3 connected to the lateral swing motor 421. The swing support 423 is slidably connected to the longitudinal adjustment screw 412. When the longitudinal adjustment motor 411 is in operation, it drives the rotation of the longitudinal adjustment screw 412. The rotation of the longitudinal adjustment screw 412 is converted into movement of the swing support 423 along the Z-axis direction, realizing the movement of the grinding head assembly 3 in the Z-axis direction.

[0052] Optional, reference Figure 2 、 Figure 3 and Figure 4 As shown, a slide rail 414 is also installed on the longitudinal adjustment support 413, and a plurality of sliders 415 matching the slide rail 414 are fixedly installed on the bottom of the swing support 423. The sliders 415 are slidably connected to the slide rail 414. When the swing support 423 moves along the longitudinal adjustment screw 412, the swing support 423 is moved along the longitudinal adjustment support 413, thereby improving the stability of the swing support 423 during operation and reducing processing errors.

[0053] According to one embodiment of the present invention, referring to Figure 3As shown, the grinding head assembly 3 includes a grinding head motor 31 and a grinding head 32, wherein the grinding head can be in the form of a grinding disc, a grinding wheel or a grinding rod, and can be selected according to the needs of the stone product to be processed. For example, a conical grinding rod can be used when polishing a cylinder. When the conical grinding rod is used to polish a cylinder, the front end of the conical grinding rod has a small diameter and wears quickly, which is suitable for polishing the small arc surface of the cylinder, while the rear end has a large diameter and wears slowly, which is suitable for polishing the surface of a large cylinder. The polishing effect and surface finish are good, the efficiency is high, and the control method is simpler than that of the grinding disc. The grinding head motor 31 is fixedly connected to the reducer 422. There is a certain angle between the direction of the output shaft of the grinding head motor 31 and the direction of the output shaft of the reducer 422. In this way, when the reducer 422 rotates, the grinding head motor 31 can swing, and the output shaft of the grinding head motor 31 is connected to the grinding head 32. When the grinding head motor 31 is working, it can drive the grinding head 32 to rotate at high speed to achieve grinding and polishing of the stone product. Optionally, the grinding head motor 31 is connected to the reducer 422 via a connecting plate 425. The chuck of the grinding head motor 31 can be a single head, or a main head with multiple chucks rotating. During the operation of the polishing machine, in order to ensure that the surface finish of the stone product meets the processing requirements, it is usually necessary to replace the grinding heads of different mesh sizes about seven times and repeatedly grind and polish.

[0054] It can be understood that the motors of the lateral moving component 1, the longitudinal moving component 2, the grinding head component 3 and the grinding head longitudinal adjustment and swinging component 4 are all controlled by the same control module. The control module can coordinate the work between the various motors through electrical connections, and can also pre-set the motion trajectory of each component of the grinder through computer profiling programming, control the motion trajectory of the grinder, and grind and polish the stone products.

[0055] According to one embodiment of the present invention, referring to Figure 3As shown, the pneumatic component 5 is connected to the longitudinal adjustment of the grinding head and the swing component 4 for rotation. Specifically, the pneumatic component 5 is hinged to the swing base 424. For example, one end of the pneumatic component 5 is hinged to the end of the swing base 424 away from the grinding head component 3, and the other end is hinged to the swing support 423. The pneumatic component 5 is used to control the swing base 424 to rotate around the swing support 423, thereby realizing the upward and downward movement of the grinding head assembly 3, controlling the distance between the grinding head assembly 3 and the surface of the stone product, and realizing automatic pressure adjustment and flexible polishing. Optionally, the pneumatic component 5 is a pneumatic valve, in which a certain amount of compressed gas is pre-stored. The compressed gas pushes the piston of the pneumatic valve to move, and the movement of the piston pushes the swing base 424 to rotate around the swing support 423, thereby driving the grinding head assembly 3 to move toward the stone product. The grinding head assembly 3 is controlled by pneumatic control to buffer the impact force generated by the contact between the grinding head assembly 3 and the surface of the stone product. When the protrusion on the surface of the stone product is large, the grinding head assembly 3 will move in the direction away from the stone product, reducing the damage to the grinding head 32 caused by the uneven surface of the stone product. By controlling the pressure of the compressed air in the pneumatic valve, the grinding head assembly 3 can also be kept in contact with the surface of the stone product during the grinding and polishing process, thereby improving the surface gloss of the stone product and enhancing the grinding effect. Optionally, the pneumatic component 5 can also be an elastic component, such as a spring or a counterweight, which can also buffer the impact force generated by the contact between the grinding head assembly 3 and the surface of the stone product. This application does not make specific restrictions.

[0056] Optionally, a pneumatic valve can be set between the grinding head 32 and the grinding head motor 31, which can also buffer the impact force between the grinding head assembly 3 and the stone product, and reduce the damage to the grinding head assembly 3 caused by the uneven surface of the stone product. The pneumatic valve can also be set in other ways. For example, a pneumatic device can be added to other directions or components such as the X-axis, Y-axis, or Z-axis of the grinder. As long as it can buffer the impact force between the grinding head assembly 3 and the stone product, this application does not make any specific restrictions on this.

[0057] The polishing machine of the embodiment of the present invention utilizes the multi-axis linkage of the lateral movement component 1, the longitudinal movement component 2, the longitudinal adjustment of the grinding head, and the swing component 4, plus the auxiliary control of the pneumatic component 5 to achieve polishing and grinding of stone products, replacing the manual polishing method. The operation method is simple, practical and fast. One person can operate multiple devices at the same time, saving labor costs and further improving production efficiency. When polishing cylindrical stone products, the cylindrical stone products can be fixed on the workbench and rotated at a low speed, and then the control module is used to control the movement of the polishing machine for polishing; when polishing special-shaped stone products, the special-shaped stone products can be fixed on the workbench and fixed, and then the control module is used to control the movement of the polishing machine for polishing, or the special-shaped stone products can be mounted on the transport platform and moved, and then the control module is used to control the movement of multiple polishing machines for polishing.

[0058] Another embodiment of the present invention provides a polishing system, including the above-mentioned polishing machine. Among them, multiple multi-axis linkage devices can be installed on the same polishing machine to realize automatic polishing of multiple special-shaped workpieces. For example, multiple polishing machines are integrated into the same horizontal moving component 1 to form an assembly line for polishing stone products, or multiple stone products are polished and polished simultaneously on the polishing system. Multiple polishing machines can work independently of each other or be used in combination to coordinate and control the polishing to achieve the surface finish requirements of the stone products. Optionally, the polishing system can be arranged in a disc-type manner, that is, multiple polishing machines are arranged in a circumferential direction, and each polishing machine works independently to form an assembly line. The stone product to be polished can also be fixed at the center of the disc-type polishing system, and multiple polishers polish the same stone product. It can also be arranged in a horizontal manner. Figure 1 As shown, multiple grinders are installed in the Y-axis direction to grind and polish a stone product at the same time, and this application does not make any specific restrictions on this.

[0059] An embodiment of the present invention provides a grinding machine, including a transverse moving component 1, a longitudinal moving component 2, a grinding head component 3, a grinding head longitudinal adjustment and swinging component 4 and a pneumatic component 5. The longitudinal moving component 2 is arranged on the transverse moving component 1, the grinding head longitudinal adjustment and swinging component 4 is slidably installed on the longitudinal moving component 2, and is connected to the grinding head component 3 to control the swing of the grinding head component 3; the pneumatic component 5 is rotationally connected to the grinding head longitudinal adjustment and swinging component 4. By controlling the forward and backward, left and right movement and swing of the grinding head assembly 3 through the longitudinal adjustment of the grinding head and the swinging assembly 4, the motion trajectory of the grinding head under the manual polishing mode can be simulated, thereby reducing errors, improving processing accuracy, reducing labor intensity, and avoiding the operational risks existing in the manual polishing mode; at the same time, by the rotational connection between the pneumatic assembly 5 and the longitudinal adjustment and swinging assembly 4 of the grinding head, the upward and downward movement of the grinding head assembly 3 can be controlled, thereby improving the overall flexibility, buffering the impact force generated by the contact between the grinding head assembly 3 and the surface of the stone product, reducing the damage to the grinding head 32 caused by the uneven surface of the stone, and ensuring that the grinding head assembly 3 is always in contact with the surface of the stone product, thereby improving the surface gloss of the stone product and enhancing the polishing effect, and is particularly suitable for polishing stone products such as special-shaped parts and large cylinders.

[0060] It is understood that the polishing machine of the present invention can also be used to polish cylindrical or shaped parts made of non-ferrous metals or other materials, such as stainless steel cylinders, while maintaining the aforementioned beneficial effects, and this application does not specifically limit this. Furthermore, compared to traditional manual operations or robotic arms, the polishing machine of the present invention offers advantages such as high structural stability, relatively simple programming, and convenient operation, significantly improving production efficiency.

[0061] The polishing machine has the beneficial effects of the above embodiment, and the polishing system has the above beneficial effects. For details, please refer to the above content and will not be repeated here.

[0062] It should be noted that the stone product can be polished and ground in sections and then polished and ground as a whole, that is, the stone product can be polished in sections first and then polished as a whole, for example, first rough-polish the lower part, then rough-polish the upper part, and then rough-polish the whole; further, medium-polish the lower part, medium-polish the upper part, and medium-polish the whole in sequence; finally, fine-polish the lower part, fine-polish the upper part, and fine-polish the whole in sequence.
