Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a vertical grinding machine for dressing the flatness of grinding wheels. Background Technology

[0002] As an important grinding tool, grinding wheels are widely used in the processing of various metal and non-metal materials. Their precision and performance play a key role in the quality of processed products. However, after prolonged use, grinding wheels will experience problems such as uneven surface and distorted shape due to wear, resulting in decreased processing accuracy and increased surface roughness, which seriously affects processing efficiency and product quality. Therefore, it is necessary to dress grinding wheels regularly to restore their geometry and grinding performance.

[0003] In the field of grinding wheel dressing and product grinding, dry grinding and wet grinding are common processing methods. When dry grinding iron products, the high-speed friction between the grinding wheel and the product generates a large amount of fine iron powder. If this powder is not treated in time, it will not only permeate the processing environment and harm the health of the operators, but also adhere to the surface of the equipment, affecting the normal operation and accuracy of the equipment, and is difficult to clean. Therefore, those skilled in the art provide a vertical grinding machine for grinding wheel flatness dressing to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a vertical grinding machine for dressing the flatness of grinding wheels, thereby solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a vertical grinding machine for dressing the flatness of grinding wheels, including a support table, a cylinder fixedly connected to the center of the upper top of the support table, a main protective frame fixedly connected to the upper top of the cylinder, two auxiliary protective frames symmetrically slidingly sleeved inside the main protective frame, a processing mechanism for grinding the product is provided on the outer wall of the main protective frame, a negative pressure mechanism for extracting gas is provided at the upper top of the processing mechanism, and an adsorption mechanism for filtering powder is provided on the side of the processing mechanism away from the main protective frame.

[0006] Preferably, the processing mechanism includes an L-shaped connecting frame fixedly connected to the outer side wall of the main protective frame. A drive motor is fixedly connected to the top end of the L-shaped connecting frame. An output shaft is fixedly connected to the output end of the drive motor. The output shaft passes through the end of the L-shaped connecting frame and is rotatably connected to the contact surface of the L-shaped connecting frame. A grinding wheel is fixedly connected to the end of the output shaft away from the drive motor.

[0007] Preferably, an electric rotary table is fixedly connected to the center of the inner bottom end of the cylinder, an output shaft is fixedly connected to the output end of the electric rotary table, and a product placement platform is fixedly connected to the end of the output shaft. The lower bottom end of the placement platform is rotatably sleeved with the upper top end of the electric rotary table.

[0008] Preferably, the negative pressure mechanism includes a gas collection hood fixedly connected to the top of the drive motor, a circular air frame sleeved on the outer wall of the grinding wheel, and a number of suction heads fixedly connected in a ring array at the bottom suction end of the circular air frame. Each suction head is fixedly connected to a gas delivery pipe for conveying gas at its end, and the end of each gas delivery pipe away from the suction head is fixedly connected to the air inlet of the gas collection hood.

[0009] Preferably, a negative pressure fan is fixedly connected to the top of the gas collection hood, the suction end of the negative pressure fan is connected to the interior of the gas collection hood, and the discharge end of the negative pressure fan is fixedly connected to an air supply pipe.

[0010] Preferably, the adsorption mechanism includes a filter cover, a bottom positioning frame is fixedly connected to the bottom of the filter cover, and a mounting frame is bolted to the top of the filter cover. An electromagnetic adsorption frame for adsorbing iron-containing powder is provided inside the mounting frame.

[0011] Preferably, a top plate is fixedly connected to the top end of the mounting frame, a filter body for filtration is placed at the inner bottom end of the bottom positioning frame, the outer side walls of the mounting frame and the bottom positioning frame are fixedly connected to the outer side wall of the main protective frame, and the conductive end of the electromagnetic adsorption frame extends to the outer side wall of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a negative pressure mechanism and an adsorption mechanism. During the dry grinding process, the grinding wheel grinds the top of the product. Due to the different materials of the products, grinding iron materials generates a large amount of fine powder. Therefore, the negative pressure mechanism can absorb the powder. Inside the mounting frame, an electromagnetic adsorption frame is installed. When gas containing powder enters the adsorption mechanism through the air supply pipe, the electromagnetic adsorption frame magnetically attracts the iron powder, thereby removing it. The gas then continues to move and is discharged after passing through the filter. The filter not only filters powder during dry grinding but also effectively absorbs the odor of the coolant during wet grinding. Furthermore, when the negative pressure mechanism is activated, the suction head is located around the grinding wheel, which accelerates the airflow around the grinding wheel. This rapid airflow effectively reduces the temperature of the local area, thereby lowering the temperature of the grinding wheel. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a vertical grinding machine for dressing the flatness of grinding wheels, including a support table 1, a cylinder 2 fixedly connected to the center of the upper top of the support table 1, a main protective frame 3 fixedly connected to the upper top of the cylinder 2, two auxiliary protective frames 6 symmetrically slidingly sleeved inside the main protective frame 3, a processing mechanism 4 for grinding the product is provided on the outer wall of the main protective frame 3, a negative pressure mechanism 5 for extracting gas is provided at the upper top of the processing mechanism 4, and an adsorption mechanism 7 for filtering powder is provided on the side of the processing mechanism 4 away from the main protective frame 3.

[0017] It should be noted that the support platform 1 serves as the base, and the main protective frame 3 is stably supported by the cylinder 2 to ensure the overall operational stability. The processing mechanism 4 is integrated into the outer wall of the main protective frame 3 and acts directly on the surface of the grinding wheel to achieve flatness repair through high-precision grinding. The negative pressure mechanism 5 at the top of the processing mechanism 4 can remove the dust and debris generated during processing in real time to avoid affecting the processing. The adsorption mechanism 7 is located on the side of the processing mechanism 4 and can effectively filter the gas to reduce odor during processing.

[0018] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2As shown, the processing mechanism 4 includes an L-shaped connecting frame 41 fixedly connected to the outer wall of the main protective frame 3. A drive motor 42 is fixedly connected to the top end of the L-shaped connecting frame 41. An output shaft is fixedly connected to the output end of the drive motor 42. The output shaft passes through the end of the L-shaped connecting frame 41 and is rotatably connected to the contact surface of the L-shaped connecting frame 41. A grinding wheel 43 is fixedly connected to the end of the output shaft away from the drive motor 42. An electric rotary table 8 is fixedly connected to the center of the inner bottom end of the cylinder 2. An output shaft is fixedly connected to the output end of the electric rotary table 8. A product placement platform 9 is fixedly connected to the end of the output shaft. The lower bottom end of the placement platform 9 is rotatably sleeved with the top end of the electric rotary table 8.

[0019] It should be noted that the L-shaped connecting frame 41 securely fixes the drive motor 42 to the side of the main protective frame 3. The drive motor 42 drives the grinding wheel 43 to rotate at high speed, performing fine grinding on the surface of the grinding wheel, effectively ensuring the flatness of the top of the workpiece. The electric rotary table 8 is built into the bottom of the cylinder 2, and its output shaft drives the placement table 9 to rotate freely 360 degrees, so that all parts of the grinding wheel are evenly ground, avoiding local over-processing or omission.

[0020] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the negative pressure mechanism 5 includes a gas collection hood 51 fixedly connected to the top of the drive motor 42. A circular air frame 53 is sleeved on the outer wall of the grinding wheel 43. Several suction heads 55 are fixedly connected in a ring array at the bottom suction end of the circular air frame 53. Each suction head 55 is fixedly connected to an air supply pipe 54 for conveying gas at its end. The end of each air supply pipe 54 away from the suction head 55 is fixedly connected to the air inlet of the gas collection hood 51. A negative pressure fan 52 is fixedly connected to the top of the gas collection hood 51. The suction end of the negative pressure fan 52 communicates with the interior of the gas collection hood 51. An air supply pipe 56 is fixedly connected to the discharge end of the negative pressure fan 52.

[0021] It should be noted that the gas collection hood 51 is fixed to the top of the drive motor 42, covering the area above the grinding wheel 43. It works with the negative pressure fan 52 to form a stable negative pressure field, ensuring that dust gathers quickly. The circular air frame 53 is fitted onto the outer wall of the grinding wheel 43. The six suction heads 55 in a ring array at its bottom end are aligned with the processing surface. The air supply pipe 54 connects each suction head 55 to the gas collection hood 51 to form a suction operation. The negative pressure fan 52 delivers the dust-laden gas to the inside of the adsorption mechanism 7 through the air supply pipe 56.

[0022] As one implementation method in this embodiment, please refer to Figure 2 - Figure 4As shown, the adsorption mechanism 7 includes a filter cover 71, a bottom positioning frame 73 is fixedly connected to the bottom end of the filter cover 71, and a mounting frame 72 is bolted to the top end of the filter cover 71. An electromagnetic adsorption frame 75 for adsorbing iron-containing powder is provided inside the mounting frame 72. A top plate 76 is fixedly connected to the top end of the mounting frame 72. A filter body 74 for filtration is placed at the bottom end of the bottom positioning frame 73. The outer walls of the mounting frame 72 and the bottom positioning frame 73 are fixedly connected to the outer wall of the main protective frame 3. The conductive end of the electromagnetic adsorption frame 75 extends to the outer wall of the mounting frame 72.

[0023] It should be noted that the filter cover 71 covers the side of the main protective frame 3, and the mounting bracket 72 has a built-in electromagnetic adsorption bracket 75. When energized, it generates a strong magnetic field, which can precisely adsorb iron-containing powder, enabling the recycling and reuse of metal powder. Figure 4 As can be seen, the filter body 74 is located inside the filter cover 71. After passing through the electromagnetic adsorption frame 75, the gas will enter the interior of 74. After being blocked by the filter body 74, the gas will be discharged. The material of the filter body 74 can be replaced according to the needs of use, such as activated carbon material that can adsorb odors and filter cloth material that can filter dust. This method can achieve diversified selection. The air inlet end of the filter body 74 and the contact surface of the electromagnetic adsorption frame 75 are squeezed and connected by a sealing ring to ensure that the gas can enter the interior of the filter body 74.

[0024] Working principle: The support platform 1 provides stable support for the whole. The cylinder 2 and the main protective frame 3 are connected in sequence to form the main frame. The auxiliary protective frame 6 can slide and adjust inside the main protective frame 3. During processing, the L-shaped connecting frame 41 fixes the drive motor 42 to the outside of the main protective frame 3. The drive motor 42 drives the grinding wheel 43 to rotate at high speed through the output shaft, and grinds the top of the product placed on the placement table 9 connected to the output end of the electric rotary table 8. The electric rotary table 8 drives the placement table 9 to rotate, so that all parts of the product are evenly ground. During the polishing process, the negative pressure fan 52 of the negative pressure mechanism 5 is started, and the air collection hood 51 generates negative pressure. The suction head 55 of the circular air frame 53 on the outer wall of the polishing wheel 43, located around the polishing wheel 43, can accelerate the air flow around it and quickly extract the powder generated by polishing. The powder is transported to the air collection hood 51 through the air supply pipe 54 and then sent to the adsorption mechanism 7 through the air delivery pipe 56. In the adsorption mechanism 7, the powder-containing gas enters the mounting frame 72, and the internal electromagnetic adsorption frame 75 magnetically removes the iron powder. The gas continues to move and is discharged after being filtered by the filter body 74 inside the bottom positioning frame 73. The filter body 74 filters powder during dry grinding and the material of the filter body 74 can be replaced during wet grinding. Different materials can absorb coolant odors or filter dust. At the same time, the suction head 55 of the negative pressure mechanism 5 accelerates airflow and effectively reduces the local temperature of the grinding wheel 43.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
