[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] A grinding plate (grinding platform) is a type of cast iron surface plate used for finishing workpieces by applying or embedding abrasive particles on it. The surface is finished through the relative motion of the grinding plate and the workpiece under pressure. It is a widely used tool in industrial production, machining, and surface treatment. Its main function is to remove surface defects, unevenness, and minor protrusions through friction and grinding, achieving the desired smoothness and finish.

[0023] Grinding plates are usually made by the three-plate method, which involves grinding three grinding plates of the same size together in a specific order. The order is that the two upper plates are each ground with a lower plate to produce two convex plates and one concave plate.

[0024] During the mutual grinding process, the two upper plates and the lower plate come into contact. Through the application of pressure and the grinding action of the abrasive, the surface of the upper plate gradually concaves inward to form a convex core, while the surface of the lower plate gradually convexes outward to form a convex core. After multiple alternating mutual grindings, the two upper plates and the lower plate respectively form two convex core plates and one concave core plate.

[0025] Next, the two convex plates are used for mutual grinding. At this stage, since the surfaces of the two convex plates are already relatively flat, their contact surfaces will be closer and smoother. Under the action of pressure and abrasive, the raised parts of the two convex plates are gradually ground flat, making the surfaces of the two plates smoother.

[0026] Finally, the concave plate is rubbed against one of the flattened plates. Since the surface of the concave plate is relatively flat, the surface of the plate in contact with it will gradually conform to the concave part of the concave plate. Under the action of pressure and abrasive, the concave part of the concave plate will be ground flat, making the surface of the entire plate smoother.

[0027] After the above three-plate grinding process, the surface of the press-ground plate is thoroughly smoothed and homogenized, resulting in excellent flatness and precision. This method not only improves the processing efficiency of the plate but also ensures its quality, meeting the needs of gauge block repair and precision machining.

[0028] Grinding plates are typically ground manually, and they come in various sizes (ranging from 100mm×200mm to 3000mm×10000mm / 4000mm×8000mm) to suit different processing needs. While manual grinding is possible when the plate area is small, it becomes difficult when the plate is large, especially during fine grinding, as the strong suction between the plates makes it impossible to move them manually.

[0029] To address the problems existing in the prior art, this utility model provides a solution. This application proposes a grinding device for a high-precision grinding plate.

[0030] Figure 1 A front view of a grinding apparatus 100 for a high-precision grinding plate according to an embodiment of the present invention is shown. Figure 2 A top view of a grinding apparatus 100 for a high-precision grinding plate according to an embodiment of the present invention is shown. Figure 3 A right view of a grinding apparatus 100 for a high-precision grinding plate according to an embodiment of the present invention is shown. Figure 4 A schematic diagram of the structure of a cylinder 130 according to an embodiment of the present invention is shown.

[0031] like Figure 1-4 As shown, the device 100 includes a base 110, a cylinder mounting bracket 120, a cylinder 130, a connector 140, a cylinder mounting seat 150, an air pump 160, and a flat plate mounting bracket 170.

[0032] The base 110 has a cuboid structure, and the cylinder mounting bracket 120 is a right trapezoidal body. Its base is fixed to the upper surface of the base 110 by bolts.

[0033] The bottom of the cylinder 130 is fixed to the side wall of the cylinder mounting bracket 120 via the cylinder mounting seat 150, so that the cylinder 130 is parallel to the upper surface of the base 110.

[0034] Specifically, the base of the cylinder mounting seat 150 is fixed to the side wall of the cylinder mounting seat 150 by bolts. A mounting component extends from the base of the cylinder mounting seat 150. The mounting component has a semi-elliptical structure. The bottom surface of the elliptical structure is fixed to the cylinder mounting seat 150, and the tip has a threaded hole, which is used to fix it to the cylinder 130.

[0035] refer to Figure 4 The cylinder 130 includes at least a cylinder chamber 131, a piston rod 132, a first air inlet 133, and a second air inlet 134.

[0036] The air pump 160 is connected to the first air inlet 133 and the second air inlet 134 through an air supply pipe, and drives the piston rod 132 to move by filling the cylinder chamber 131 with compressed gas.

[0037] In some embodiments, when the air pump 160 delivers compressed gas into the cylinder chamber 131 through the first air inlet 133, the piston rod 132 moves in a first direction; when the air pump 160 delivers compressed gas into the cylinder chamber 131 through the second air inlet 134, the piston rod 132 moves in a second direction, the first direction being opposite to the second direction. In other words, by intermittently delivering compressed gas to the first air inlet 133 and the second air inlet 134 by the air pump 160, the piston rod 132 can reciprocate within the cylinder chamber 131.

[0038] It is worth noting that when the air pump 160 delivers compressed gas to the first air inlet 133, the second air inlet 134 will act as an air outlet, discharging the gas outside the space formed by the cylinder chamber 131 and the top of the piston rod 132. Conversely, when the air pump 160 delivers compressed gas to the second air inlet 132, the first air inlet 131 will act as an air outlet, discharging the gas within the space formed by the cylinder chamber 131 and the top of the piston rod 132. This reduces the resistance during the movement of the piston rod 132.

[0039] In some embodiments, the compressed gas can be compressed air. This embodiment uses compressed air as a power source, which has advantages such as readily available raw materials and low cost.

[0040] The connector 140 is arranged between the piston rod 132 and the first grinding plate 200 for connecting the piston rod 132 and the first grinding plate 200.

[0041] In some embodiments, the connector 140 includes a universal floating joint 141, a fixed shaft 142, and a rotating shaft 143.

[0042] The universal floating joint 141 is arranged between the piston rod 132 and the fixed shaft 142 to connect the piston rod 132 and the fixed shaft 142. The working principle of the universal floating joint 141 is to absorb errors by relaxing the degrees of freedom, thereby making the movement of the piston rod 132 smoother. The main function of the universal floating joint 141 is to connect two shafts (piston rod 132 and fixed shaft 142) in different mechanisms, allowing them to rotate together to transmit power. In high-speed, heavy-load power transmission, the universal floating joint 141 can also play a role in buffering, vibration reduction, and improving the dynamic performance of the shaft system. Its principle is that several different degrees of freedom are set during installation, which prevents the movement of the piston rod 132 from being blocked due to installation errors, thereby extending the service life of the piston rod 132.

[0043] When installed, the fixed shaft 142 is perpendicular to the piston rod 132, and the end of it away from the universal floating joint 141 is sleeved on the rotary shaft 143.

[0044] The rotary shaft 142 is an important component widely used in mechanical equipment. It has functions such as bearing axial and radial loads and supporting rotational motion.

[0045] A rotary shaft 143 generally consists of an inner ring, an outer ring, rolling elements, and a cage. The inner and outer rings are annular structures, the rolling elements are spherical or roller-shaped, and the cage is used to fix the position of the rolling elements.

[0046] When the mechanical equipment needs to rotate, the rotary shaft 143 is installed on the rotating part of the equipment. During the rotation, the inner and outer rings rotate relative to each other, while the rolling elements roll between them, thus enabling the transfer of load.

[0047] The rotary shaft 143 can withstand various types of loads, including radial loads, axial loads, and bending moments. Radial loads refer to forces perpendicular to the axis, while axial loads refer to forces parallel to the axis.

[0048] The rolling elements of the rotary shaft 143 can roll between the inner and outer rings, thereby supporting the rotational motion of the mechanical equipment. This structure can reduce friction and improve the operating efficiency of the equipment.

[0049] The cage in the rotating shaft 143 is used to fix the position of the rolling elements and prevent them from colliding with each other or falling out of the bearing. At the same time, the cage can also distribute the load, reduce friction, and reduce noise.

[0050] The bottom of the rotary shaft 143 is fixed to the first grinding plate 200 via a plate fixing bracket 170. The plate fixing bracket 170 is arranged on the opposite side of the grinding surface of the first grinding plate 170 and wraps around and fixes the opposite side. The side of the plate fixing bracket 170 away from the opposite side is provided with a fixing structure for fixing the rotary shaft 143. Through this fixing structure, the rotary shaft 143 and the plate fixing bracket 170 can be fixedly connected, thereby realizing the fixed connection between the connector 140 and the first grinding device 200.

[0051] The second grinding plate 300 is fixed on the upper surface of the base 110, and the first grinding plate 200 and the second grinding plate 300 are arranged opposite to each other. When the air pump 160 delivers compressed gas into the cylinder 130, the piston rod 132 drives the first grinding plate 200 to reciprocate on the surface of the second grinding plate 300.

[0052] It should be noted that when it is necessary to adjust the contact position between the grinding surface of the first grinding plate 200 and the grinding surface of the second grinding plate 300, the contact position between the grinding surface of the first grinding plate 200 and the grinding surface of the second grinding plate 300 can be changed through the universal floating joint 141.

[0053] The device 100 of this utility model uses mechanical means to replace manual labor for the processing of high-precision grinding plates, which has the advantages of high processing efficiency and simple operation. Furthermore, the device 100 also has the advantages of simple structure, low requirements for component processing, and low production cost.

[0054] Furthermore, the device 100 performs mutual grinding between the first plate to be ground 200 and the second plate to be ground 300. When there is only one plate to be ground 400, the device 100 cannot be used to grind the plate to be ground 400. Based on this, this application also provides a high-precision grinding plate grinding device 500 to achieve grinding processing of the plate to be ground 400 when there is only one plate to be ground 400.

[0055] Figure 5 A front view of a grinding apparatus 500 for a high-precision grinding plate according to another embodiment of the present invention is shown.

[0056] like Figure 5 As shown, the device 500 includes a base 510, a cylinder holder 520, a cylinder 530, a connector 540, a cylinder mounting base 550, and a grinding table 560.

[0057] Compared to the aforementioned device 100, device 500 arranges a grinding table 580 at the position where the second grinding plate 200 is originally fixed. This grinding table 580 can be a pre-ground grinding plate, used to grind the grinding platform 100. Apart from this, the remaining structure of device 500 is similar to that of device 100, and related descriptions can be found in the description of device 100; they will not be repeated here.

However, it will be understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Furthermore, it should be noted that the language used in this specification has been chosen primarily for readability and instructional purposes, and not for the purpose of interpreting or limiting the subject matter of the invention.
