Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing, and in particular to a grinding and polishing device for parts used in mechanical manufacturing and a use method thereof. Background Art

[0002] Grinding and polishing is a very important processing technology in industrial processing. Grinding refers to the process of using machinery to increase the roughness of the workpiece surface to obtain patterns or remove burrs on the workpiece surface. Polishing is the process of using machinery to reduce the roughness of the workpiece surface to obtain a bright and smooth surface. The equipment for grinding and polishing is basically the same. The difference is that grinding is to contact the workpiece surface with a grinding wheel, and polishing is to contact the workpiece surface with a polishing wheel. They both use a high-speed rotating grinding wheel or polishing wheel to press against the workpiece, and the abrasive on the surface of the grinding wheel or polishing wheel rolls and slightly cuts the workpiece surface, thereby obtaining a carved, burred or bright processed surface.

[0003] The existing parts grinding and polishing devices have many technical defects when in use. First, the current grinding structure and polishing structure can only achieve linear motion, so for workpieces with annular structures, the work efficiency and processing effect are not good; second, the workpiece will generate dust during grinding and polishing, so a vacuum cleaner will be used. The current vacuum cleaner has a small dust collection range, resulting in poor dust collection effect and a poor work workshop environment; third, polishing powder is sprinkled on the workpiece during polishing by manual powder sprinkling, which is time-consuming and labor-intensive, and the uniformity of the sprinkling is insufficient. At the same time, the wet polishing powder is not dispersed well, which further leads to uneven distribution.

[0025] A method for using a machine manufacturing parts grinding and polishing device comprises the following steps: S1: First, place the workpiece to be processed into the middle position of the upper end surface of the workpiece table for positioning, then start the screw motor, drive the workpiece table to move into the inner chamber of the grinding mechanism through transmission, and use the grinding wheel to rotate and make circular motion to grind the upper end surface of the workpiece.

[0026] S2: The polished workpiece is then moved along with the workpiece cone to the workpiece cooling zone for a short cooling process.

[0027] S3: Finally, the screw motor is started to drive the workpiece table to move into the inner chamber of the polishing mechanism through the transmission, and the upper end surface of the workpiece is polished by the polishing wheel while rotating and moving in a circular motion.

[0028] The present invention provides a machine manufacturing parts grinding and polishing device and a method of using the same through improvement, which has the following significant improvements and advantages compared with the prior art: (1) First start the lifting cylinder, the cylinder rod extends downward to drive the middle table down until the lower end of the positioning roller is pressed in the middle position of the upper end surface of the workpiece, which plays a role in positioning and pressing to prevent the workpiece from displacement. At the same time, the grinding wheel (or polishing wheel) contacts the upper end surface of the workpiece, and then start the servo motor and the drive motor synchronously. The annular drive seat rotates slowly, so that the connecting column drives the outer seat of the wheel to make a circular motion. The grinding wheel (or polishing wheel) rotates and makes a circular motion on the workpiece, and the edge of the workpiece is evenly ground or polished. It is suitable for the processing of annular workpieces and improves work efficiency.

[0029] (2) Start the uniform speed motor to drive one of the vertical shafts to rotate, and through the synchronous transmission of the external chain and several sets of synchronous sprockets, each set of vertical shafts rotates. After a series of transmissions of the bevel gear converter, when the protrusion of the No. 1 cam contacts the pulley during the movement, the wheel platform and the lifting rod move upward, causing the dust suction pipe to extend upward along the pipe hole for a distance. When the protrusion of the No. 1 cam leaves the pulley, the lifting rod and the dust suction pipe return to their positions downward. This is repeated, so that each set of dust suction pipes changes the dust suction position in the vertical direction, thereby expanding the dust suction range and significantly improving the dust suction effect.

[0030] (3) With the help of the power of the wheel axle, the small sprocket rotates with it, and the coaxial material distribution roller is driven by the chain connection transmission to position and rotate at a uniform speed in the sealed shell. When the receiving trough on the material distribution roller passes through the material guide pipe during movement, it will receive some polishing powder that falls from the material guide pipe. Then, the receiving trough carrying the polishing powder will pass through the discharge port during the downward movement, and the dry polishing powder in the receiving trough will be released instantly. The polishing powder is thrown downward onto the moving polishing wheel surface, which can achieve uniform throwing and automatically control the amount of polishing powder thrown, saving time and effort.

[0031] (4) With the help of the power of the material distribution roller seat, the No. 2 cam coaxial with the material distribution roller seat makes a circular motion. When the protruding part of the No. 2 cam contacts the piston rod during the movement, it pushes the piston rod to move linearly. The piston rod drives the piston seat to move in the cylinder cavity to squeeze the humidifying water in the cylinder cavity. The humidifying water enters the humidifying atomization head through the drain pipe at a high speed. The humidifying water is dispersed into small droplets through the humidifying atomization head and is evenly injected onto the surface of the polishing wheel to absorb the polishing powder, thereby achieving the effect of automatic humidification and improving the polishing effect with the polishing powder.

At this time, the lifting cylinder 32 is started first, and the cylinder rod 33 extends downward, driving the intermediate table 34 to descend (the guide block 35 moves downward along the guide column 92) until the lower end of the positioning roller 49 is pressed in the middle position of the upper end surface of the workpiece 4, and the grinding wheel contacts the upper end surface of the workpiece 4.

[0058] At this time, the servo motor 44 and the drive motor 54 are started synchronously, and the drive gear 45 rotates, thereby causing the annular drive seat 40 to rotate slowly through meshing, so that the connecting column 46 drives the wheel outer seat 50 to make a circular motion, and the grinding wheel rotates and makes a circular motion on the workpiece 4, so as to evenly grind the edge of the workpiece 4 all around, and repeatedly grind the rough surface of the workpiece 4 to be smooth.

[0059] During the grinding process, the dust suction fan 21 works, and the dust particles generated by grinding are timely absorbed by the dust suction pipes 23 evenly distributed on the workpiece truncated table 18, and are introduced into the dust suction box 20 through the bellows 22, and are collected by the dust collecting net. At the same time, the uniform speed motor 95 is started to drive one group of vertical shafts 286 to rotate, and through the synchronous transmission of the outer chain 94 and several groups of synchronous sprockets 288, each group of vertical shafts 286 rotates, causing the second bevel gear 285 on the vertical shaft 286 to rotate, and the second bevel gear 285 is meshed with the first bevel gear 284 on one side, thereby driving the second bevel gear 285 to rotate. The coaxial cam No. 281 of the first bevel gear 284 makes a circular motion. When the protrusion of the No. 1 cam 281 contacts the pulley 27 during the motion, the two generate a relative force causing the wheel platform 25 and the lifting rod 24 to move upward, so that the dust suction pipe 23 extends upward along the pipe hole 93 for a distance. When the protrusion of the No. 1 cam 281 leaves the pulley 27, the lifting rod 24 and the dust suction pipe 23 are driven downward by the restoring elastic force of the tensioning spring 26. This is repeated, so that each group of dust suction pipes 23 changes the dust suction position in the vertical direction, thereby expanding the dust suction range.

[0060] After the grinding operation is completed, the screw motor 12 is started again. After a series of transmissions, the workpiece table 18 is moved into the inner chamber 7 of the polishing mechanism 6. According to the same operating method as the grinding mechanism 5, the polishing wheel 52 rotates and moves in a circle on the workpiece 4, and the edge of the workpiece 4 is evenly polished (while throwing wet polishing powder on the workpiece 4). Repeated polishing improves the flatness and glossiness of the surface of the workpiece 4.

[0061] Embodiment 2 On the basis of the first embodiment, the polishing powder is sprinkled on the workpiece 4 by manual powdering during polishing, which is time-consuming and laborious, and the uniformity of the sprinkle is insufficient. At the same time, the wet polishing powder falls and disperses poorly. In order to solve the above technical problems, we have the following design, such as Figure 12-16 shown.

[0062] Specifically, a material storage tank 60 is provided inside the connecting column 46 of the polishing mechanism 6. The material storage tank 60 is bucket-shaped from top to bottom for easy material discharge. Polishing powder is stored in the material storage tank 60. A material guide pipe 61 is provided at the bottom of the material storage tank 60 and extends outwardly. The lower end of the material guide pipe 61 is located at the upper end surface of the wheel outer seat 50 and is connected to a sealing shell 62. Fig.12 and 13 shown.

[0063] Among them, a material distribution roller seat 63 is fitted in the sealing shell 62, which is a sliding seal. A material receiving groove 64 is provided on the annular surface of the material distribution roller seat 63 (the width of the material receiving groove 64 is greater than the width of the material guide tube 61, so that the material receiving groove 64 can receive a certain amount of polishing powder during movement), and a discharge port 65 is provided at the bottom of the sealing shell 62 to connect with the material receiving groove 64. The discharge port 65 is located above the polishing wheel 52, such as Fig.14 and 15 shown.

[0064] Furthermore, short shafts 66 are symmetrically welded at both ends of the material distribution roller seat 63, and an inner bearing 67 is provided at the connection between each set of short shafts 66 and the sealing shell 62. The end of the short shaft 66 away from the material distribution roller seat 63 is fixed by the fourth bearing seat 68 and the outer wall of the wheel outer seat 50. Figure 13-15 shown.

[0065] In this example, a large sprocket 70 is sleeved on one of the short shafts 66, and a small sprocket 71 is sleeved on the wheel shaft 51. The large sprocket 70 and the small sprocket 71 are connected by a chain 72. Fig.13 shown.

[0066] In this example, a second cam 73 is sleeved on another set of short shafts 66, and a humidifying structure 8 is disposed outside the second cam 73. Figure 13-15 shown.

[0067] Specifically, the humidification structure 8 includes a humidification cylinder 81, a mounting frame 82, a cylinder cavity 83, a piston seat 84, a piston rod 85, a return spring 86, a slider 87 and a drainage hole 88. Fig.16 shown.

[0068] In this embodiment, the outer side surface of the humidifying cylinder 81 is fixed to the end surface of the sealing shell 62 by means of a mounting frame 82, and a cylinder cavity 83 is horizontally opened inside the humidifying cylinder 81, and humidifying water is injected into the cylinder cavity 83. A piston seat 84 is provided in the cylinder cavity 83 for sliding sealing, and a piston rod 85 is connected to the middle position of the end surface of the piston seat 84. The piston rod 85 extends outward through the barrel mouth of the humidifying cylinder 81, and a slider 87 acting on the wheel surface of the No. 2 cam 73 is provided at the end of the piston rod 85 away from the piston seat 84. A return spring 86 sleeved on the outside of the piston rod 85 is connected between the piston seat 84 and the barrel mouth of the humidifying cylinder 81, and the return spring 86 is used to maintain the contact force between the slider 87 and the No. 2 cam 73.

[0069] The oblique bottom of the cylinder cavity 83 is provided with a drainage hole 88, in which a first one-way valve is installed. The first one-way valve automatically opens under the action of water pressure. A drainage pipe 74 is connected to the outside of the drainage hole 88, and a humidifying atomizing head 75 acting on the polishing wheel 52 is connected to the lower end of the drainage pipe 74. The installation angles of the drainage pipe 74 and the humidifying atomizing head 75 are designed according to actual conditions, such as Figure 13-16shown.

[0070] Among them, a water inlet is opened at one end of the cylinder cavity 83 away from the cylinder mouth, and a second one-way valve is installed in the water inlet. The second one-way valve plays a one-way flow blocking role to prevent the water in the cylinder cavity 83 from being pressed into the water inlet pipe 76. The water inlet is connected to the outside of the water inlet. The end of the water inlet pipe 76 is connected to a water storage tank 77. The water storage tank 77 is set through the outer side of the wheel outer seat 50. Figure 12-14 shown.

[0071] Furthermore, the upper end surface of the wheel outer seat 50 is provided with a sprocket receiving groove 97 for receiving the large sprocket 70, which plays a role in receiving the large sprocket 70. Fig.12 shown.

[0072] When this embodiment is in use, while the wheel axle 51 drives the polishing wheel 52 to rotate, the wheel axle 51 will cause the small sprocket 71 to rotate along with it, and the connection transmission through the chain 72 will cause the large sprocket 70 to slow down and rotate, thereby driving the coaxial material distribution roller seat 63 to be positioned and rotated at a uniform speed in the sealed shell 62. When the material receiving groove 64 on the material distribution roller seat 63 passes through the material guide pipe 61 during movement, it will receive part of the polishing powder that falls from the material guide pipe 61. Then, the material receiving groove 64 carrying the polishing powder will pass through the discharge port 65 during downward movement, and the dry polishing powder in the material receiving groove 64 will be released instantly. The polishing powder is thrown downward onto the moving polishing wheel 52 wheel surface, and as the polishing wheel 52 and the workpiece 4 contact and act on the workpiece 4, uniform throwing can be achieved.

[0073] At the same time, when the material distribution roller seat 63 rotates, the No. 2 cam 73 coaxial with the material distribution roller seat 63 makes a circular motion. When the protruding part of the No. 2 cam 73 contacts the piston rod 85 during the circular motion, a relative force is generated with the slider 87, thereby pushing the piston rod 85 to move in a straight line. The piston rod 85 drives the piston seat 84 to move in the cylinder cavity 83 to squeeze the humidifying water in the cylinder cavity 83. The humidifying water presses the first one-way valve to open and enters the humidifying atomizing head 75 through the drain pipe 74 at a higher speed. The humidifying water is dispersed into small droplets through the humidifying atomizing head 75 and is evenly injected onto the wheel surface of the polishing wheel 52 to absorb the polishing powder. When the protruding part of the No. 2 cam 73 leaves the position of the slider 87, the elastic force of the reset spring 86 causes the piston rod 85 and the piston seat 84 to return to their original positions, and the humidifying water in the water storage tank 77 is injected into the cylinder cavity 83 through the water inlet pipe 76 as a supplement, and the cycle is repeated.
