Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a polishing machine. Background Technology

[0002] In the field of modern precision manufacturing, grinding and polishing machines are core equipment for achieving high-precision surface processing of workpieces. They are widely used in key industries such as machining and electronics manufacturing. Whether it is the mirror treatment of automotive parts or the nano-level polishing of semiconductor chips, the processing quality directly affects the performance and lifespan of the products. However, traditional grinding and polishing equipment still has shortcomings in actual production, which restricts the further improvement of processing efficiency and ease of operation.

[0003] In the polishing process of existing grinding and polishing machines, in order to ensure that the workpiece surface is in full contact with the polishing paper, it is usually necessary to apply pressure above the workpiece using a pressure applying mechanism. However, this traditional design has significant drawbacks: the vertically arranged pressure applying structure occupies the space directly above the workpiece loading area. When the operator places the workpiece, the pressure applying structure will cause some obstruction to the placement of the workpiece, and the narrow space will also affect the accuracy of assembly. Based on this, this application proposes a grinding and polishing machine. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a grinding and polishing machine to solve the problems mentioned in the background art.

[0006] Optionally, a first groove is provided at the top left end of the base and below the lifting block. A first hydraulic rod is installed in the first groove, and the telescopic end of the first hydraulic rod is fixedly connected to the bottom of the lifting block. A support ring is sleeved on one end of the crossbar near the storage frame, and support rods are fixedly connected between the two sides of the support ring and the right end of the lifting block.

[0007] Optionally, the pressure application assembly includes a connecting plate, a tilting plate, a lifting plate, and a pressure plate. A second fixing member is fixedly installed on the left end of the top of the lifting block. The left end of the connecting plate is sleeved on the second fixing member. The tilting plate is fixedly installed on the end of the connecting plate away from the second fixing member. Through holes are arranged in a circular array on the tilting plate, with the same number of holes as the number of placement holes and aligned one by one.

[0008] Optionally, a first fixing member is fixedly installed at the bottom of the left end of the lifting block, and a third hydraulic rod is hinged to the first fixing member. The telescopic end of the third hydraulic rod is hinged to the left end of the connecting plate. A support block is fixedly installed at the right end of the top of the lifting block. When the connecting plate is in a horizontal state, the bottom of the connecting plate contacts the top of the support block.

[0009] Optionally, a frustum is provided at the center of the bottom of the water collection tank, and a second groove is provided at the center of the top of the frustum. A motor is fixedly installed in the second groove, and the output end of the motor is fixedly connected to the center of the bottom of the rotating platform.

[0010] Optionally, a fixing ring is fixedly installed at the bottom of the rotating platform and sleeved on the side of the truncated cone.

[0015] By inserting the rod at the bottom of the connecting block at the edge of the pressure ring into the slot on the side wall of the rotary table, the polishing paper can be tightly pressed onto the top of the rotary table, preventing the paper from shifting during the polishing process, ensuring the flatness of the polished surface, and improving the surface processing accuracy of the workpiece.

[0016] The pressure plate in the pressure assembly has a rubber layer at the bottom, and the connecting rod and the connecting tube are connected by a spring. When the second hydraulic rod is pressed down, the spring can buffer the pressure, and the rubber layer ensures that the workpiece surface is subjected to uniform force, avoiding workpiece damage caused by rigid pressure.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a polishing machine, including a base 1, a water collection tank 2 on the top of the base 1, a rotatable rotating platform 4 installed in the water collection tank 2, the diameter of the top of the rotating platform 4 being smaller than the diameter of its bottom, and the top of the rotating platform 4 being flush with the top of the base 1, a polishing paper 5 of suitable size covering the top of the rotating platform 4, a pressure ring 6 fitted on the edge of the top of the rotating platform 4 pressing against the polishing paper 5, and a water-blocking ring 7 fitted on the top of the outer wall of the water collection tank 2, the water-blocking ring 7 effectively blocking water or polishing liquid splashed during the polishing process, keeping the working environment clean. A lifting block 11 is installed on the left end of the top of the base 1. A crossbar 111 extending to the top of the rotating table 4 is fixedly connected to one end of the lifting block 11. A storage frame 112 is fixedly installed on the end of the crossbar 111 away from the lifting block 11. Multiple vertically penetrating storage holes 1121 are opened in a circular array on the top of the storage frame 112. A flip-up pressure component is provided above the lifting block 11 and the storage frame 112. By flipping the pressure component at an angle, it can avoid the space above the storage frame 112, solving the problem that the pressure structure of traditional equipment hinders the loading of workpieces and improving the ease of operation.

[0020] like Figure 1 and Figure 2As shown, a first groove is provided at the top left end of the base 1, below the lifting block 11. A first hydraulic rod 10 is installed in the first groove, and the telescopic end of the first hydraulic rod 10 is fixedly connected to the bottom of the lifting block 11. A support ring 113 is sleeved on one end of the crossbar 111 near the storage frame 112. Support rods are fixedly connected between the two sides of the support ring 113 and the right end of the lifting block 11. The first hydraulic rod 10 drives the lifting block 11 to rise and fall. The position of the storage frame 112 can be adjusted according to the workpiece height or operation requirements to enhance the adaptability of the equipment. The cooperation between the support ring 113 and the support rod enhances the support strength of the crossbar 111 and the storage frame 112, avoids shaking caused by load or pressure, and ensures processing accuracy.

[0021] like Figure 3 and Figure 4 As shown, the pressure-applying assembly includes a connecting plate 121, a flipping plate 122, a lifting plate 123, and a pressure plate 126. A second fixing member 115 is fixedly installed on the left end of the top of the lifting block 11. The left end of the connecting plate 121 is sleeved on the second fixing member 115. The flipping plate 122 is fixedly installed on the end of the connecting plate 121 away from the second fixing member 115. Through holes are arranged in a circular array on the flipping plate 122, with the same number of holes as the placement holes 1121 and aligned one by one. A connecting tube 124 is movably inserted into each through hole. The pressure plate 126 is fixedly installed on the top end of the multiple connecting tubes 124. A connecting tube 124 is movably inserted into the bottom end of each connecting tube 124. There is a connecting rod 125, and a spring 127 is fixedly connected between the top end of the connecting rod 125 and the top end of the inner wall of the connecting tube 124. A pressure plate 126 is fixedly installed at the bottom end of each connecting rod 125. A rubber layer is provided at the bottom of each pressure plate 126. A second hydraulic rod 128 is installed at the center of the bottom of the flip plate 122. The telescopic end of the second hydraulic rod 128 passes through the flip plate 122 and is fixedly connected to the center of the bottom of the pressure plate 126. Through the cooperation of the spring 127 and the rubber layer, the pressure plate 126 can provide sufficient pressure to ensure that the workpiece contacts the polishing paper 5 when applying pressure, and can also buffer to avoid damage to the workpiece, which is especially suitable for precision workpieces.

[0022] like Figure 1 and Figure 3As shown, a first fixing member 114 is fixedly installed at the bottom left end of the lifting block 11. A third hydraulic rod 13 is hinged to the first fixing member 114. The telescopic end of the third hydraulic rod 13 is hinged to the left end of the connecting plate 121. A support block 116 is fixedly installed at the right end of the top of the lifting block 11. When the connecting plate 121 is in a horizontal state, the bottom of the connecting plate 121 contacts the top of the support block 116. The telescopic end of the third hydraulic rod 13 can drive the connecting plate 121 to connect with the second fixing member 115 as the center. By flipping the connecting plate 121 and the flipping plate 122, the position of the pressure-applying component can be adjusted so that the pressure-applying component is not directly above the storage frame 112. This makes it easier to place the workpiece into the storage hole 1121 on the storage frame 112. The support block 116 can provide support for the connecting plate 121 when it is in a horizontal state, so that the flipping plate 122 and the storage frame 112 are parallel to each other, which makes it easier for the pressure plate 126 to enter the storage hole 1121 to apply a certain pressure to the workpiece.

[0023] like Figure 2 As shown, a frustum is provided at the center of the bottom of the water collection tank, and a second groove is provided at the center of the top of the frustum. A motor 3 is fixedly installed in the second groove. The output end of the motor 3 is fixedly connected to the center of the bottom of the rotating platform 4. By starting the motor 3, power can be provided for the rotation of the rotating platform 4.

[0024] like Figure 2 and Figure 5 As shown, a fixing ring 9 is fixedly installed on the bottom of the rotating platform 4 and sleeved on the side of the truncated cone. Multiple ball grooves are evenly arranged inside the fixing ring 9, and each ball groove is provided with a rotatable ball 91. An annular groove 8 is opened on the side wall of the truncated cone. The part of each ball 91 that extends out of the ball groove is located in the annular groove 8 and can roll inside it. The ball 91 inside the fixing ring 9 cooperates with the annular groove 8 of the truncated cone to convert sliding friction into rolling friction, reduce rotational resistance, reduce wear, extend equipment life, and make rotation smoother.

[0025] like Figure 2 and Figure 5 As shown, the slope of the side wall of the rotating table 4 is provided with multiple slots 41 in a circular array. The outer side of the pressure ring 6 is provided with connecting blocks 61 in the same number as the slots 41 in a circular array. The bottom of the connecting blocks 61 fits against the slope of the side wall of the rotating table 4, and each connecting block 61 is fixedly installed with a plug rod 62 that is inserted into the corresponding slot 41. Through the insertion and cooperation of the plug rod 62 at the bottom of the connecting block 61 with the slot 41 on the side wall of the rotating table 4, the installation of the pressure ring 6 can be positioned, and the stability of the installation of the pressure ring 6 can be increased, ensuring that the polishing paper 5 is evenly pressed and avoiding loosening during processing.

[0026] like Figure 1 and Figure 2As shown, the bottom of the water collection tank is set as an inclined surface, and the right end of the bottom of the water collection tank is at a lower horizontal height. A drain outlet 21 communicating with the water collection tank is opened on the right side of the base 1. A drain pipe 22 is fixedly installed on the right side of the base 1 at the drain outlet 21. The wastewater generated during the polishing process is collected in the water collection tank 2 and flows into the drain pipe 22 through the drain outlet 21 along the inclined surface at the bottom of the water collection tank 2, thereby realizing the discharge of wastewater.
