[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 6 , the present invention provides a technical solution: See also Figure 1-Figure 6As shown, a grinding device with an adjustable cone roller angle function includes a work table 1 and a mounting frame 2, the mounting frame 2 is arranged above the work table 1, a servo motor 3 is arranged on one side of the mounting frame 2, the driving end of the servo motor 3 is connected to a grinding wheel 10, the grinding wheel 10 is rotatably connected to the mounting frame 2, the driving end of the servo motor 3 is connected to a first transmission mechanism 4, the first transmission mechanism 4 is connected to a second transmission mechanism 26, the other end of the second transmission mechanism 26 is rotatably connected to a reciprocating screw 5, the reciprocating screw 5 is rotatably connected to the mounting frame 2, a filter screen 7 is fixedly installed on the mounting frame 2, a scraper 6 is threadedly connected to the reciprocating screw 5, and a suction device 8 is fixedly installed on the side of the filter screen 7 away from the grinding wheel 10.

[0021] The servo motor 3 is started, and its driving end outputs power to drive the grinding wheel 10 to rotate at high speed on the mounting frame 2 to perform grinding operations on workpieces such as the tapered roller 20 placed on the work table 1.

[0022] While the grinding wheel 10 is rotating, the driving end of the servo motor 3 also transmits power to the second transmission mechanism 26 through the first transmission mechanism 4. The second transmission mechanism 26 then drives the reciprocating screw 5 to rotate on the mounting frame 2. Since the scraper 6 is threadedly connected to the reciprocating screw 5, as the reciprocating screw 5 rotates, the scraper 6 will reciprocate along the reciprocating screw 5. In this process, the scraper 6 can scrape off the debris and dust attached to the surface of the filter screen 7, prevent the filter screen 7 from being blocked, and ensure the filtering effect of the filter screen 7.

[0023] The suction device 8 continuously works on the side of the filter screen 7 away from the grinding wheel 10, generating negative pressure, and sucking the debris and dust generated during the grinding process through the filter screen 7. The filter screen 7 plays a filtering role, preventing large particles of debris from entering the suction device 8, protecting the suction device 8, and at the same time discharging the filtered air to achieve the purpose of purifying the working environment.

[0024] Compared with the conventional dust suction device installed on the table below the cone roller 20, the combination of the air suction device 8 and the filter screen 7 is closer to the grinding wheel 10 and can better cover the area where debris and dust may splash. Even if the debris and dust splash in a complex trajectory, they can be sucked in to a greater extent, effectively improving the dust suction efficiency and solving the problem of difficulty in covering the splashing area.

[0025] See also Figure 3-4 A first guide rod is fixedly mounted on the inner wall of the mounting frame 2, and one end of the scraper 6 away from the reciprocating screw rod 5 is slidably connected to the first guide rod.

[0026] The first guide rod provides additional support and guidance for the scraper 6, so that when the scraper 6 makes reciprocating linear motion along the reciprocating screw 5, it will not shake or deviate due to the influence of lateral force or other external force, thereby ensuring the smooth movement of the scraper 6, so that the debris and dust on the surface of the filter 7 can be scraped off more accurately and stably.

[0027] See also Figure 1-2 A mounting frame is fixedly installed on the top of the work table 1, a variable current motor 11 is installed on one side of the mounting frame, a first screw rod 12 is connected to the driving end of the variable current motor 11, and a first slider 13 is threadedly connected to the outer wall of the first screw rod 12.

[0028] The variable current motor 11 drives the first screw 12 to rotate, and the first slider 13 can move linearly along the screw direction under the threaded connection of the outer wall of the first screw 12. By controlling the speed and rotation direction of the variable current motor 11, the moving speed and position of the first slider 13 can be accurately controlled. Since the cone roller 20 is usually installed on a structure associated with the first slider 13, the position of the cone roller 20 in the horizontal direction can be accurately adjusted so that it reaches the best relative position with the grinding wheel 10, thereby improving the grinding accuracy and effect.

[0029] See also Figure 1-2 A universal ball device 15 and a second mounting plate 16 are installed on the top of the work table 1, a first mounting plate 14 is installed on the top of the universal ball device 15, a DC motor 21 is arranged on one side of the second mounting plate 16, a driving end of the DC motor 21 is connected to a bidirectional screw rod 22, the bidirectional screw rod 22 is rotatably connected to the second mounting plate 16, a second slider 23 is threadedly connected to the bidirectional screw rod 22, the bottom end of the second slider 23 is rotatably connected to a mounting rod 24, the other end of the mounting rod 24 is rotatably connected to the top of the work table 1, and a tapered roller 20 is arranged between the universal ball device 15 and the second mounting plate 16.

[0030] The universal ball device 15 allows the first mounting plate 14 and the cone roller 20 connected thereto to rotate freely within a certain range, thereby achieving fine adjustment at multiple angles. At the same time, the DC motor 21 drives the bidirectional screw 22 to rotate, so that the second slider 23 slides on the bidirectional screw 22, and drives the second mounting plate 16 and one end of the cone roller 20 to rise and fall through the mounting rod 24, thereby changing the inclination angle of the cone roller 20. This design can flexibly adjust the angle of the cone roller 20 to meet the grinding needs of workpieces of different shapes and sizes, thereby improving the versatility and adaptability of the grinding device.

[0031] It not only provides a multi-angle free adjustment function, so that the inclination angle of the tapered roller 20 can be flexibly adjusted to meet different grinding needs, but also is more convenient to operate than the traditional fixed structure, and the processing angle can be quickly changed without disassembly. The DC motor 21 drives the bidirectional lead screw 22 to achieve electric precision adjustment to avoid manual operation errors, and the second slider 23 and the mounting rod 24 form a connecting rod mechanism to convert the linear motion of the lead screw into the angle change of the tapered roller 20, so that the adjustment process is smoother. The tapered roller 20 is located between the universal ball device 15 and the second mounting plate 16. The universal ball device 15 provides dynamic support to ensure that the tapered roller 20 maintains stable contact when the angle is adjusted. The second mounting plate 16 serves as a rigid reference to prevent the tapered roller 20 from being offset due to force, thereby improving the grinding accuracy. The universal ball device 15 is responsible for rapid coarse angle adjustment, and the bidirectional lead screw 22 system achieves fine-tuning locking, taking into account both efficiency and accuracy.

[0032] Furthermore, it is suitable for grinding complex curved surfaces and has strong versatility. The design solves the problems of inflexible angle adjustment and insufficient precision of traditional grinding devices by combining the universal ball device 15 with the bidirectional screw 22 mechanism, and is particularly suitable for processing scenarios where the angle of the tapered roller 20 needs to be adjusted frequently.

[0033] See also Figure 1-2 A turntable 17 is rotatably connected between the first mounting plate 14 and the second mounting plate 16 , an elastic member 18 is mounted on the turntable 17 , and a clamping block 19 is mounted on the other end of the elastic member 18 .

[0034] The presence of the elastic member 18 prevents the clamping block 19 from damaging the workpiece surface due to excessive clamping force when clamping the workpiece. When the clamping block 19 is impacted by external force or the workpiece surface is uneven, the elastic member 18 can play a buffering role to avoid rigid contact between the clamping block 19 and the workpiece, thereby effectively protecting the integrity and smoothness of the workpiece surface, and is particularly suitable for grinding workpieces with high surface quality requirements.

[0035] The clamping block 19 is used to clamp the cone roller 20, and cooperates with the elastic member 18 to provide a stable clamping force to prevent the cone roller 20 from shaking or shifting during the grinding process, thereby ensuring the accuracy and stability of the grinding. In addition, the clamping block 19 is provided with a mounting groove adapted to the cone roller 20, and is provided with anti-slip rubber, which further enhances the clamping effect of the cone roller 20, prevents it from sliding, and protects the surface of the cone roller 20 from damage.

[0036] See also Figure 1 The first transmission mechanism 4 includes a small gear 401 , which is meshedly connected with a large gear 402 , and the large gear 402 is rotatably connected to the outer wall of the installation frame 2 .

[0037] The gear transmission structure is relatively compact, occupies little space, and can effectively realize power transmission in the limited space of the mounting frame 2. At the same time, the meshing connection between the gears is relatively stable, can withstand a certain load, and is not prone to slippage or loosening, thereby ensuring the reliability and stability of the grinding device during long-term operation.

[0038] The meshing of the small gear 401 and the large gear 402 can change the direction of power transmission, so that the power can be transmitted from the servo motor 3 to the second transmission mechanism 26 and the reciprocating screw rod 5 and other components in a suitable direction. At the same time, by matching the small gear 401 and the large gear 402 with different numbers of teeth, the transmission speed can be adjusted to meet the specific speed requirements of the reciprocating motion of the scraper 6, so as to effectively clean the filter 7.

[0039] The gear transmission efficiency is high. In the process of transmitting the power of the servo motor 3 to the reciprocating screw 5, it can reduce energy loss, ensure sufficient power to drive the scraper 6 to work, and then ensure the cleaning effect of the filter 7, maintain the normal operation of the suction device 8 and the purification effect of the working environment.

[0040] The large gear 402 is rotatably connected to the outer wall of the mounting frame 2, providing a stable support structure for the entire transmission system. This connection method allows the first transmission mechanism 4 and the mounting frame 2 to form a relatively stable whole, which can withstand the force generated during the gear transmission process when the grinding device is working, reduce vibration and shaking, and improve the reliability and service life of the device.

[0041] When the small gear 401 drives the large gear 402 to rotate, the speed of the large gear 402 will be reduced. See also Figure 5 The clamp block 19 is provided with a mounting groove matched with the tapered roller 20, and the interior of the mounting groove is provided with anti-slip rubber.

[0042] The anti-slip rubber in the mounting groove can increase the friction between the tapered roller 20 and the clamping block 19, effectively preventing the tapered roller 20 from sliding or rotating during the grinding process, ensuring the stability of the grinding operation, and avoiding grinding errors or safety accidents caused by the movement of the tapered roller 20.

[0043] The anti-slip rubber is soft in texture and can prevent the clamping block 19 from causing damage to the surface of the tapered roller 20 while clamping the tapered roller 20, thereby protecting the tapered roller 20. This protection is especially important for tapered rollers 20 that require higher surface accuracy.

[0044] The mounting groove is adapted to the tapered roller 20 , so that the tapered roller 20 can be accurately placed in the clamping block 19 , thereby ensuring the position accuracy of the tapered roller 20 during the grinding process, which is beneficial to improving the accuracy and consistency of the grinding.

[0045] See also Figure 1A tensioning component 9 is fixedly installed between the mounting frame 2 and the first sliding block 13 .

[0046] The mounting groove is adapted to the tapered roller 20, so that the tapered roller 20 can be accurately placed in the clamping block 19, achieving precise positioning, ensuring the position accuracy of the tapered roller 20 during the grinding process, and being conducive to improving the accuracy and consistency of the grinding.

[0047] The presence of the anti-slip rubber increases the friction between the clamping block 19 and the tapered roller 20, effectively preventing the tapered roller 20 from sliding or shifting during the grinding process. Even if the grinding device vibrates or is subjected to external forces during operation, the tapered roller 20 can remain stable, thereby improving the quality and stability of the grinding.

[0048] See also Figure 3-4 , the filter screen 7 is arranged at an inclination.

[0049] The inclined filter screen 7 can make it easier for debris and impurities generated during the grinding process to slide down along the surface of the filter screen 7. The inclined filter screen 7 can make it easier for debris to slide down along the inclined surface under the action of gravity, avoiding the accumulation of debris on the filter screen 7, ensuring the smoothness of chip removal, and helping to maintain the cleanliness of the grinding device. At the same time, the filter screen 7 has an enhanced blocking effect on debris, and can more effectively intercept debris of different sizes and shapes. See also Figure 3-4 A water tank is installed at the bottom of the installation frame 2, and the water tank is arranged below the filter screen 7. A grip plate 25 is connected to one side of the turntable 17.

[0050] The water tank is located below the filter 7, providing a centralized collection field for dust, so that the dust and impurities generated during the grinding process can be gathered in the water tank, preventing the dust from falling directly on the ground or the work table 1, and further maintaining the cleanliness of the working environment. At the same time, the water in the water tank can also play a certain role in settling the dust, reducing the suspension of dust in the air, reducing air pollution, and benefiting the health of the operator. It is convenient for unified cleaning, preventing dust from scattering around the grinding device, and keeping the working area clean.

[0051] The gripping plate 25 provides an easy-to-hold and force-applying position for the operator. By rotating the gripping plate 25, the turntable 17 can be easily driven to rotate, thereby adjusting the angle of the tapered roller 20. This design enables the operator to control the angle of the tapered roller 20 more accurately and conveniently, improves the precision and efficiency of grinding, and also reduces the labor intensity of the operator.

[0052] Working principle: The servo motor 3 is started, and its driving end outputs power to drive the grinding wheel 10 to rotate at high speed on the mounting frame 2 to perform grinding operations on workpieces such as the tapered roller 20 placed on the work table 1.

[0053] While the grinding wheel 10 is rotating, the driving end of the servo motor 3 also transmits power to the second transmission mechanism 26 through the first transmission mechanism 4. The second transmission mechanism 26 then drives the reciprocating screw 5 to rotate on the mounting frame 2. Since the scraper 6 is threadedly connected to the reciprocating screw 5, as the reciprocating screw 5 rotates, the scraper 6 will reciprocate along the reciprocating screw 5. In this process, the scraper 6 can scrape off the debris and dust attached to the surface of the filter screen 7, prevent the filter screen 7 from being blocked, and ensure the filtering effect of the filter screen 7.

[0054] The suction device 8 continuously works on the side of the filter screen 7 away from the grinding wheel 10, generating negative pressure, and sucking the debris and dust generated during the grinding process through the filter screen 7. The filter screen 7 plays a filtering role, preventing large particles of debris from entering the suction device 8, protecting the suction device 8, and at the same time discharging the filtered air to achieve the purpose of purifying the working environment.

[0055] Compared with the conventional dust suction device installed on the table below the cone roller 20, the combination of the air suction device 8 and the filter screen 7 is closer to the grinding wheel 10 and can better cover the area where debris and dust may splash. Even if the debris and dust splash in a complex trajectory, they can be sucked in to a greater extent, effectively improving the dust suction efficiency and solving the problem of difficulty in covering the splashing area.
