Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, and more specifically, to a thrust ball bearing ring end face groove grinding machine. Background Art

[0002] Thrust ball bearings are a type of bearing designed to withstand axial forces. They are designed to withstand thrust loads when running at high speeds. They consist of a washer-shaped ring with a raceway groove for ball rolling. Since the ring is seat-shaped, thrust ball bearings are divided into two types: flat seat pad type and self-aligning spherical seat pad type.

[0003] When processing and producing bearings, a groove grinder is usually used. This grinder is mainly used for precision machining of the end face grooves of thrust ball bearing rings. It grinds the end face grooves of the rings through the rotation and feed motion of the grinding wheel to achieve the geometric shape, dimensional accuracy and surface roughness required by the design. It can achieve precise control of the end face grooves of the rings and improve the overall machining accuracy of the bearings.

[0004] When using a groove grinder to process bearings, in order to ensure that the grinding wheel can accurately process the bearings and ensure the service life of the grinding wheel, cooling water is usually used to cool the grinding wheel and bearings. During processing, the grinding wheel will produce a large amount of debris, and the cooling water will cover the debris to prevent it from splashing. However, after the cooling water is bent for cooling and dust reduction, the wastewater will contain oil and debris, which can easily cause blockage and pollution when discharged. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the utility model provides a thrust ball bearing ring end face groove grinding machine, comprising a workbench 1, a work chamber 2 is fixedly installed on the top of the workbench 1, an observation window 3 is fixedly installed on the front side of the work chamber 2, a fixed seat 4 is fixedly installed inside the work chamber 2, a transmission shaft 7 is rotatably installed on the left side of the fixed seat 4, and a grinding wheel 8 is fixedly installed on the left side of the transmission shaft 7;

[0034] A drain port 13 is fixedly provided on the left side of the fixing base 4, a guide bin 14 is fixedly installed on the bottom of the workbench 1, the guide bin 14 and the drain port 13 are connected to each other, a square electromagnet 15 is fixedly installed inside the guide bin 14, a drain bin 16 is fixedly installed at the bottom of the guide bin 14, brackets 17 are fixedly installed on the left and right sides of the drain bin 16, and a sieve plate 18 is placed on the top of the two sets of brackets 17;

[0035] A mounting plate 19 is fixedly installed on the rear side of the sieve plate 18, and a fixed head 20 is movably installed on the rear of the drainage bin 16. One end of the fixed head 20 is elastically connected to the inner wall of the drainage bin 16 by a spring 21, and the other end of the fixed head 20 passes through the inside of the mounting plate 19 to fix the mounting plate 19. An outlet pipe 23 is fixedly installed on the front side of the drainage bin 16.

[0036] When grinding operations are required, the staff first ensures that there is sufficient water inside the water tank 11, and then connects the square electromagnet 15 to the power supply to complete the preparation operation. The staff then fixes the thrust ball bearing inside the limit ring 29 and starts the motor 2 26 to move the bearing to the inside of the working bin 2. At this time, the staff starts the motor 15 and the water pump 12 to start the grinding operation. When the motor 15 is running, the transmission shaft 16 rotates, and the transmission shaft 16 and the transmission shaft 2 7 are connected by the transmission belt 9 to rotate the grinding wheel 8 to grind the bearing. At the same time, the operation of the water pump 12 draws the cooling water inside the water tank 11 and sprays it out from the nozzle 10 to cool the grinding wheel 8 and the bearing and suppress dust. At this time, the wastewater will flow into the diversion bin 14 through the drain port 13, and flow into the drainage bin 16 through the guidance of the square electromagnet 15. When the wastewater flows through the square electromagnet 15, the square electromagnet 15 will absorb the debris contained in the waste liquid. After the wastewater enters the drainage tank 16, the wastewater is centrally treated and discharged through the outlet pipe 23. After the grinding operation is completed, the staff operates the motor 15 and the water pump 12 and cuts off the power supply of the square electromagnet 15. The debris that has lost its adsorption force will fall into the sieve plate 18 along the square electromagnet 15 for collection. At this time, the staff can pull the control lever 22 to make the fixed head 20 squeeze the spring 21 and detach from the inside of the mounting plate 19. At this time, the staff can pull out the sieve plate 18 through the mounting plate 19 and centrally treat the debris inside it. After the treatment is completed, the staff resets the sieve plate 18 and releases the control lever 22. Through the elastic potential energy of the spring 21, the fixed head 20 is reset and the mounting plate 19 is fixed.

[0037] Through the operation of the water pump 12, the grinding wheel 8 can be cooled and dust suppressed by cooling water during grinding. The waste water is discharged from the outlet pipe 23 through the magnetic adsorption and diversion of the square electromagnet 15, and the solid debris falls into the sieve plate 18 after the square electromagnet 15 is powered off. Finally, after the grinding is completed, the mounting plate 19 can be pulled out from the drainage bin 16 by pulling the control lever 22 to process the debris. Compared with the traditional device, the device uses the magnetic adsorption of the square electromagnet 15 to fix the metal debris under the bearing grinding by the square electromagnet 15, so that the waste liquid can be easily discharged, reducing the burden of waste liquid treatment. The metal debris is collected centrally through the sieve plate 18, which is convenient for the subsequent centralized treatment and reuse of these metal debris, thereby improving the environmental protection efficiency during operation.

A clamping plate 31 is movably installed inside the fixed block 30, and a screw 32 is rotatably installed inside the fixed block 30. The screw 32 and the clamping plate 31 are threadedly connected.

[0040] Before performing the grinding operation, the staff can place the bearing inside the mounting plate 19 and rotate the two sets of screws 32. The rotation of the screws 32 drives the clamping plate 31 threadedly connected to it to move along the fixed block 30 toward the inside of the limit ring 29. Furthermore, the two sets of clamping plates 31 fix the bearing inside the limit ring 29. Then the staff starts motor 26. The operation of motor 26 drives the screw 27 to rotate, and the screw 27 drives the fixed platform 28 threadedly connected to it to move to the inside of the working chamber 2. Furthermore, the staff can control the grinding time of the bearing through motor 26.

[0041] By rotating the screw 32, the screw 32 drives the clamping plate 31 threadedly connected thereto to move along the fixed block 30 toward the inside of the limit ring 29, thereby fixing the bearing. By operating the motor 26, the fixed platform 28 is moved to the inside of the working bin 2 for grinding. Compared with the traditional device, this device fixes the bearing through two sets of clamping plates 31, which is simple to operate and fast to fix. By operating the motor 26, the bearing is sent into the inside of the working bin 2, which prevents debris from overflowing during grinding, ensures the working environment, and reduces the workload.

[0046] The operation of the water pump 12 draws cooling water from the water tank 11 and sprays it out from the nozzle 10 to cool the grinding wheel 8 and the bearing and suppress dust.

[0047] A transverse groove 24 is fixedly provided on the rear side of the drainage bin 16 , and a control rod 22 is movably installed inside the transverse groove 24 , and one end of the control rod 22 is fixedly connected to the fixed head 20 .

[0048] The staff can pull the control rod 22 to move the control rod 22 along the transverse groove 24, further separating the fixing head 20 from the interior of the mounting plate 19, thereby completing the disassembly of the mounting plate 19.

[0049] Among them, the model of the square electromagnet 15 is XDA-150 / 60 / 50, which is responsible for absorbing debris.

[0050] It is worth noting that the square electromagnet 15 is a prior art, and when current flows through its wire, a magnetic field is generated around the wire.

[0051] One end of the clamping plate 31 is movably mounted inside the fixing block 30 , and the other end is disposed inside the limiting ring 29 . The clamping surface of the clamping plate 31 is arc-shaped.

[0053] The staff starts the motor 2 26 , and the operation of the motor 2 26 drives the screw 27 to rotate, and the screw 27 drives the fixed platform 28 threadedly connected to it to move to the inside of the working chamber 2 . Furthermore, the staff can control the grinding time of the bearing through the motor 2 26 .

[0054] The adsorption surface of the square electromagnet 15 is installed obliquely inside the diversion chamber 14 and is responsible for the diversion operation.

[0055] The square electromagnet 15 guides the waste liquid into the drainage bin 16 and magnetically absorbs the debris to achieve solid-liquid separation.

[0056] The working principle and use process of this utility model:

[0057] When grinding operations are required, the staff first ensures that there is sufficient water inside the water tank 11, and then connects the square electromagnet 15 to the power supply to complete the preparation operation. The staff then fixes the thrust ball bearing inside the limit ring 29 and starts the motor 2 26 to move the bearing to the inside of the working bin 2. At this time, the staff starts the motor 15 and the water pump 12 to start the grinding operation. When the motor 15 is running, the transmission shaft 16 rotates, and the transmission shaft 16 and the transmission shaft 2 7 are connected by the transmission belt 9 to rotate the grinding wheel 8 to grind the bearing. At the same time, the operation of the water pump 12 draws the cooling water inside the water tank 11 and sprays it out from the nozzle 10 to cool the grinding wheel 8 and the bearing and suppress dust. At this time, the wastewater will flow into the diversion bin 14 through the drain port 13, and flow into the drainage bin 16 through the guidance of the square electromagnet 15. When the wastewater flows through the square electromagnet 15, the square electromagnet 15 will absorb the debris contained in the waste liquid. After the wastewater enters the drainage tank 16, the wastewater is centrally treated and discharged through the outlet pipe 23. After the grinding operation is completed, the staff operates the motor 15 and the water pump 12 and cuts off the power supply of the square electromagnet 15. The debris that has lost its adsorption force will fall into the sieve plate 18 along the square electromagnet 15 for collection. At this time, the staff can pull the control lever 22 to make the fixed head 20 squeeze the spring 21 and detach from the inside of the mounting plate 19. At this time, the staff can pull out the sieve plate 18 through the mounting plate 19 and centrally treat the debris inside it. After the treatment is completed, the staff resets the sieve plate 18 and releases the control lever 22. Through the elastic potential energy of the spring 21, the fixed head 20 is reset and the mounting plate 19 is fixed.

[0058] Before performing the grinding operation, the staff can place the bearing inside the mounting plate 19 and rotate the two sets of screws 32. The rotation of the screws 32 drives the clamping plate 31 threadedly connected to it to move along the fixed block 30 toward the inside of the limit ring 29. Furthermore, the two sets of clamping plates 31 fix the bearing inside the limit ring 29. Then the staff starts motor 26. The operation of motor 26 drives the screw 27 to rotate, and the screw 27 drives the fixed platform 28 threadedly connected to it to move to the inside of the working chamber 2. Furthermore, the staff can control the grinding time of the bearing through motor 26.
