Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gear processing, in particular to a gear edge grinding tool and a grinding process. Background Art
[0002] Gear is a mechanical transmission element that transmits power and motion through the meshing of gear teeth. It is widely used in various mechanical equipment and has the characteristics and functions of transmitting power, changing speed and torque, precise transmission, adapting to different directions and forms of motion, and improving mechanical efficiency. According to different classification standards, it can be divided into spur gears, helical gears, bevel gears, worm gears, etc.
[0003] Gear corners refer to the sharp edges at the junction of the gear tooth surface and the tooth top or tooth root. During the meshing process of the gears, the gear tooth surfaces need to contact smoothly to ensure uniform force transmission and reduce wear. If the gear corners are too sharp during the design and manufacturing process of the gears, it may cause stress concentration, increased wear, noise and vibration, poor lubrication and other problems. Therefore, the gear corners are usually properly processed, such as chamfering or rounding, to reduce the impact of the above problems. This can improve the performance and life of the gears and ensure the reliability and efficiency of the transmission system.
[0004] The existing gear edge grinding device may have the following problems during use:
[0005] Existing edge grinding devices can only clamp and fix gears of specific sizes and shapes, lack versatility, and are often rigidly fixed when clamping and fixing them. Although the rigid clamping and fixing of gears can provide high precision and stability, stress concentration will occur at the clamping points of the fixture and the gear during the clamping process, especially at the corners or edges of the gear, which will cause cracks or deformation in these areas of the gear, affecting the performance of the gear after processing. In addition, when the fixture clamps and fixes the gear, the friction between the contact surface of the fixture and the gear will cause wear on the surface of the fixture. As time goes by, if the fixture wears too much, the clamping force of the fixture on the gear will be weakened or unevenly distributed, affecting the stability and accuracy of the clamping, which will cause the gear to deform or grind unevenly, resulting in a decrease in processing accuracy, thereby affecting the final processing quality.
[0006] Therefore, the present invention proposes a gear edge grinding tool and a grinding process to make up for and improve the deficiencies of the prior art. Summary of the invention

[0026] (III) Beneficial effects
[0027] The gear edge grinding tool and grinding process provided by the present invention have the following beneficial effects:
[0028] 1. By distributing the clamps in a circular array, the clamps can clamp and fix the gears from the central axis of the gear to the surrounding areas at the same time. When the clamping force is applied to the surrounding areas at the same time, the clamping force will act evenly on the inner diameter of the gear from the middle to the surrounding areas, so that the force on the gear can be more uniform, and the internal stress concentration of the gear during the clamping process can be reduced, and the gear can be prevented from cracking or deforming in these sensitive areas, thereby reducing the risk of gear deformation. The connecting column connected to the clamp is connected to the slider through a spring. The spring has a certain elasticity and can adapt to gears of different sizes within a certain range, thereby improving the versatility of the tooling and being suitable for diversified production needs. It can also adapt to the slight shape differences of the gears to a certain extent, provide a tighter fit and a better clamping effect, further enhance the stability of the clamping, and buffer the impact of the clamping force on the gear, reducing the risk of local deformation and damage of the gear caused by rigid clamping.
[0029] 2. By rotating the connected retaining ring on the outer surface of the spray pipe, and the adjustment hole opened on the retaining ring surface and the spray port opened on the spray pipe surface are located in the same vertical section, when in use, the user can adjust the spray amount of the coolant according to the gear material to be ground, grinding requirements and tool characteristics, so that the device can provide an appropriate amount of coolant according to the specific grinding requirements, ensure that the gear is fully cooled during the grinding process, avoid gear quality problems caused by overheating, such as burns, deformation, etc., reduce the impact of grinding heat on the surface quality of the gear, reduce surface roughness, improve the accuracy and surface integrity of the gear, and reduce the use of coolant and cost while meeting the cooling requirements. At the same time, it also reduces the workload of coolant treatment and recycling. At the same time, different gear materials have different thermal conductivity and grinding characteristics, and the spray amount of coolant can be adjusted according to the characteristics of the material to achieve the best grinding effect.
[0030] 3. By setting the upper surface of the auxiliary block to be high on all sides and low in the middle, the vertical section is in the shape of a "concave" character, and the through holes evenly penetrated through the surface are connected to the liquid storage tank, so that the used coolant can be filtered by the filter cotton through the through holes and collected into the liquid storage tank for reuse, thereby reducing the discharge of coolant and reducing pollution to the environment. It is avoided that the coolant may contain harmful substances, which will cause harm to the soil, water sources, etc. if discharged directly. When the connecting rod 2 drives the push block to move through the slider 2, the push block pushes the filter cotton used for filtering through the auxiliary rod, so that the filter cotton can be automatically replaced after being used for a period of time, avoiding As the filter cotton is used for a longer time, its filtering effect will gradually decrease. Make sure the filter cotton is always in an effective filtering state, thereby ensuring the filtering quality of the coolant after use, removing impurities and particulate matter, ensuring the cleanliness of the coolant after filtration, and enabling the coolant to better play a cooling and lubricating role when it is reused. Automatic replacement of filter cotton can also reduce manual intervention, save operation time, and reduce errors caused by improper operation or negligence, such as forgetting to replace the filter cotton or failing to replace the filter cotton in time. It can also reduce the operator's chance of contact with coolant and filter cotton, reduce occupational health risks, and improve the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] refer to Fig.13 According to another preferred embodiment of the present invention
[0056] A gear edge grinding process includes the following steps:
[0057] Step 1, gear installation: insert the gear to be ground into the outer surface of the fixture 8, and by rotating the adjustment plate 11, the slide column 9 sliding inside the slide groove 12 drives the slider 1 5 to move from the center point of the fixed plate 4 to the surroundings. When the slider 1 5 moves, it drives the fixture 8 to move through the connecting column 7. After the fixture 8 moves, the gear to be ground is firmly clamped on the fixture;
[0058] Step 2: Tool installation and adjustment: Select a suitable grinding tool according to the gear to be ground, and install the grinding tool on the tool mounting seat 28, and adjust the position and angle of the tool through the fixing block 26 and the adjusting block 27 to match the grinding position and angle of the edge of the gear to be ground;
[0059] Step 3: Grinding parameter setting: according to the gear material to be ground, grinding requirements and tool characteristics, set the appropriate grinding speed, feed rate and grinding depth;
[0060] Step 4: Grinding operation: Start the grinding equipment and make the tool grind the edges and corners of the gear to be ground according to the set parameters. During the grinding process, pay attention to observe the grinding conditions to ensure the grinding quality and dimensional accuracy.
[0061] Step 5: Inspection and adjustment: After grinding the gear for a certain period of time, stop the grinding equipment and inspect the grinding size and surface quality of the gear edges. If there is a size deviation or surface quality problem with the ground gear, adjust the grinding parameters or tool position in time and perform correction grinding;
[0062] Step 6. Complete grinding: After the grinding size and surface quality of the gear edges meet the requirements, stop the grinding operation, remove the gear from the outer surface of the fixture 8, and clean the gear to remove grinding debris and coolant residue. Then check the edges of the gear to ensure that its size, shape and surface quality meet the design requirements, maintain and service the grinding equipment, and prepare for the next grinding work.
[0063] When installing and adjusting the tool in the above step 2, ensure that the grinding tool is firmly fixed on the tool mounting seat 28 to prevent movement or shaking during the grinding process, and select a grinding tool with sharpness and precision suitable for the gear to be ground to adapt to the gear material and grinding requirements.
[0064] Step 4: When performing grinding operations, operators should wear protective glasses and protective gloves, and comply with the safe operating procedures of the grinding equipment to avoid accidents. Adjust the amount of coolant spray to control the grinding temperature to avoid excessive temperature causing changes in gear material properties or thermal cracks. Pay attention to the surface quality of the gears during the grinding process. If the surface roughness does not meet the requirements or defects occur, adjust the grinding parameters in time or take appropriate measures to repair it. Avoid excessive grinding in a certain part that may cause gear shape and size deviations. Regularly check the wear of the grinding tool and replace severely worn tools in time to ensure grinding quality.
[0065] The following is the entire working process and working principle of the above embodiment:
[0066] When in use, first, insert the gear to be ground into the outer surface of the fixture 8, and then rotate the adjustment plate 11. When the adjustment plate 11 rotates, it drives the slide groove 2 12 opened on the surface of the adjustment plate 11 to rotate. When the slide groove 2 12 rotates, it pushes the slide column 9 slidably connected to the inside of the slide groove 2 12 to move in the direction away from the center line of the fixed plate 4. When the slide column 9 moves, it drives the slider 1 5 connected to the slide column 9 to move in the direction away from the center line of the fixed plate 4. When the slider 1 5 moves, it drives the fixture 8 to move in the direction away from the center line of the fixed plate 4 through the connecting column 7. After the fixture 8 moves, it firmly clamps the gear to be ground on the tooling. Since the fixture 8 is distributed in a circular array, the fixture 8 clamps and fixes the gear from the central axis of the gear to the surrounding areas at the same time. When the clamping force is applied to the surrounding areas at the same time, The clamping force will act evenly on the inner diameter of the gear from the middle to the surrounding areas, which can make the force on the gear more uniform, reduce the internal stress concentration of the gear during the clamping process, prevent the gear from cracking or deforming in these sensitive areas, thereby reducing the risk of gear deformation. In addition, since the connecting column 7 connected to the clamp 8 is connected to the slider 5 through a spring 6, the spring 6 has a certain elasticity and can adapt to gears of different sizes within a certain range, thereby improving the versatility of the tooling and being suitable for diversified production needs. In addition, it can adapt to the slight shape differences of the gears to a certain extent, provide a tighter fit and a better clamping effect, further enhance the stability of the clamping, and buffer the impact of the clamping force on the gear, reducing the risk of local deformation and damage of the gear caused by rigid clamping.
[0067] Next, according to the gear to be ground, a suitable grinding tool is selected and installed on the tool mounting seat 28. Since the portion of the adjusting block 27 connected to the tool mounting seat 28 and the fixed block 26 is set to be spherical, the user can adjust the position and angle of the tool installed on the adjusting block 27 by rotating the adjusting block 27 to match the grinding position and angle of the edge of the gear to be ground. Then, the fixing pin 2 30 is inserted into the fixing hole 29 opened at the corresponding position on the surface of the tool mounting seat 28, and the adjusted adjusting block 27 is fixed. According to the material of the gear to be ground, the grinding requirements and the tool characteristics, the appropriate grinding speed, feed rate and grinding depth are set;
[0068] Furthermore, the user adjusts the spraying amount of the coolant by rotating the retaining ring 34 according to the gear material to be ground, grinding requirements and tool characteristics, and by adjusting the overlapping area of the adjustment hole 35 opened on the surface of the retaining ring 34 and the spray port 33 opened on the surface of the spray pipe 32. This allows the device to provide an appropriate amount of coolant according to specific grinding requirements, ensure that the gear is fully cooled during the grinding process, avoid gear quality problems caused by overheating, such as burns, deformation, etc., reduce the impact of grinding heat on the surface quality of the gear, reduce surface roughness, and improve the accuracy and surface integrity of the gear. On the premise of meeting the cooling requirements, the amount of coolant used is reduced, the cost is reduced, and the workload of coolant treatment and recycling is also reduced. At the same time, since different gear materials have different thermal conductivity and grinding characteristics, the spraying amount of the coolant can be adjusted according to the characteristics of the material to achieve the best grinding effect.
[0069] Secondly, the grinding equipment is started, and the tool is used to grind the edges and corners of the gear to be ground according to the set parameters. During the grinding, the coolant in the liquid storage tank 3 is transported to the inside of the spray pipe 32 through the delivery pipe 31, and then sprayed on the gear grinding part through the overlapped area of the adjustment hole 35 and the spray port 33, so as to cool the gear being ground;
[0070] Furthermore, since the upper surface of the auxiliary block 2 is set to be high on all sides and low in the middle, and the vertical section is in the shape of a "concave" character, the temperature coolant can flow to the lower middle part of the upper surface of the auxiliary block 2 after use. Since the auxiliary block 2 is connected to the liquid storage tank 3 through the through holes evenly opened on the surface, and the auxiliary block 2 is provided with a filter sponge 22 inside the cavity of the auxiliary block 2, the used coolant will be filtered by the filter sponge 22 before flowing into the liquid storage tank 3 through the through holes, so that the coolant collected in the liquid storage tank 3 can be reused, thereby reducing the discharge of the coolant, reducing pollution to the environment, and avoiding the coolant containing harmful substances, which may cause harm to the soil, water sources, etc. if directly discharged;
[0071] Reference Figure 5 - Attachment Fig. 9Furthermore, when the gear is ground, the driving device connected to the fixed plate 4 drives the fixed plate 4 to rotate, and the fixed plate 4 drives the meshing groove 16 opened on the surface to rotate. When the meshing groove 16 rotates, it drives the gear body 15 meshing with the meshing groove 16 to rotate. When the gear body 15 rotates, it drives the connecting rod 17 to rotate through the connecting shaft. When the connecting rod 17 rotates, it drives the slider 2 19 connected to it through the connecting rod 2 18 to slide in the cavity of the auxiliary block 2. The slider 2 1 When sliding, the push block 21 sliding inside the slider 19 is driven to move. When the slider 19 drives the push block 21 to slide rightward to the auxiliary rod 23, the inclined surface of the auxiliary rod 23 pushes the push block 21 to move in the direction close to the connecting rod 18. At this time, the spring 20 connected to the slider 19 is compressed, and the slider 19 continues to drive the push block 21 to slide rightward. The auxiliary rod 23 no longer pushes the push block 21 to move in the direction close to the connecting rod 18. The restoring force of the spring 20 drives the push block 21 to slide rightward. The push block 21 moves in the direction away from the connecting rod 2 18, and then the connecting rod 1 17 drives the sliding block 2 19 to slide to the left through the connecting rod 2 18. When the sliding block 19 slides to the left, the sliding block 19 pushes the filter sponge 22 fixedly connected to the auxiliary rod 23 to move through the auxiliary rod 23, and the filter sponge 22 that has been used for a period of time is replaced to avoid that the filtering effect of the filter sponge 22 will gradually decrease with the increase in the use time of the filter sponge 22, thereby ensuring that the filter sponge 22 is always in an effective filtering state, thereby ensuring the filtration quality of the coolant after use, removing impurities and particulate matter therein, ensuring the cleanliness of the coolant after filtration, and enabling the coolant to better play a cooling and lubricating role when it is reused. Automatic replacement of the filter cotton can also reduce manual intervention, save operation time, and reduce errors caused by improper operation or negligence, such as forgetting to replace the filter sponge 22 or failing to replace the filter sponge 22 in time. It can also reduce the chance of operators contacting with coolant and filter cotton, reduce occupational health risks, and improve the working environment.
[0072] Finally, after the grinding size and surface quality of the gear edges meet the requirements, the grinding operation is stopped, and the user rotates the adjustment plate 11. The adjustment plate 11 drives the slider 5 connected to the slide column 9 to move toward the center line of the fixed plate 4 through the slide groove 12. When the slider 5 moves, it drives the clamp 8 to move toward the center line of the fixed plate 4 through the connecting column 7. After the clamp 8 moves, the user removes the ground gear from the outer surface of the clamp 8, cleans the gear, removes grinding debris and coolant residue, and then checks the edges of the gear to ensure that its size, shape and surface quality meet the design requirements, and maintains and maintains the grinding equipment to prepare for the next grinding work.
