Description

Technical Field

[0001] The invention relates to the technical field of textile machinery processing, and in particular to a bearing inner ring grinding device and a method suitable for textile machinery. Background Art

[0002] Textile machinery is the full name of tools that process raw materials such as thread, silk, and hemp into silk threads and then weave them into cloth. However, as an important component of textile machinery, the main function of bearings is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the processing of shafts and bearings, the inner rings need to be polished so that the bearings can better cooperate with other accessories.

[0003] During the polishing process of the inner ring of the bearing, a polishing abrasive disc is required for grinding. When the abrasive disc is polished and rotated, a rotational force is generated, which makes the bearing tend to slide toward the surrounding outer walls, thereby causing the bearing to shift, reducing the polishing accuracy, and failing to polish the inner rings of bearings of different specifications.

[0014] Preferably, one end of the first connecting tube is connected to the outside of the collecting box, and polishing liquid is provided inside the collecting box.

[0015] A method for using a bearing inner ring grinding device suitable for textile machinery comprises the following steps:

[0016] Step 1: Place the bearing to be processed on the top of the mounting base plate, and then start the first cylinder to drive it to move. Then, the swing rod will swing, and the arc clamping plate will swing under the traction force of the swing rod, and the arc clamping plate will be used to clamp the inner ring of the bearing;

[0017] Step 2: After clamping the bearing, cooperate with the electric guide rail and the electric slider to extend the grinding disc into the inner side of the inner ring of the bearing. At this time, by moving the moving block upward or downward, the hinged rod is driven to swing, and the grinding disc is driven to move outward under the traction force of the hinged rod until the grinding disc can be closely contacted with the inner wall of the inner ring of the bearing. At this time, the driving plate is moved left and right along the outer wall of the screw by rotating the screw. At this time, as the driving plate moves, one end of the rotating rod is driven to swing. Under the traction force of the rotating rod, one end of the plug rod is stuck into the socket to ensure the fixed position of the grinding disc;

[0018] Step 3: When the dual-axis servo motor is started, it will drive the driving assembly to work, and the driving assembly will drive the movable rod to move repeatedly, and then drive the movable plate to move repeatedly along the inner wall of the fixed cylinder, so that the inside of the fixed cylinder is constantly formed in a negative pressure state. Since the fixed cylinder is connected to the fixed box through the air intake pipe, a negative pressure state will be generated inside the dust removal pipe, and the dust generated during the grinding of the inner ring of the bearing will be absorbed into the inside of the fixed box;

[0019] Step 4: Start the pump body to transport the polishing liquid in the collection box into the spray pipe through the first connecting pipe and the second connecting pipe, and discharge it through the spray pipe. The discharged polishing liquid flows on the outer surface of the filter and flows back to the collection box. At this time, the impurity absorption electromagnet is energized to generate magnetism to absorb metal impurities in the polishing liquid, thereby ensuring the recovery effect of the polishing liquid.

[0020] The present invention provides a bearing inner ring grinding device and method suitable for textile machinery, which has the following beneficial effects:

[0021] The present invention drives the hinged rod to swing by moving the moving block upward or downward, and drives the grinding disc to move outward under the action of the traction force of the hinged rod until the grinding disc can be in close contact with the inner wall of the inner ring of the bearing, thereby improving the polishing effect of the inner ring of the bearing and the polishing accuracy. At the same time, the present invention can polish the inner rings of bearings of different specifications, greatly improving the flexibility of use of the device.

[0022] The present invention uses a fixed cylinder, a first connecting pipe, a fixed box, a second connecting pipe and other components to enable dust generated during the grinding process of the bearing to be sucked into the interior of the fixed box through a dust removal pipe, thereby improving the grinding working environment, reducing the harm of dust to workers, and facilitating centralized treatment of dust.

[0023] 3. The present invention circulates the polishing liquid back and forth between the collection box, the first connecting pipe and the second connecting pipe by means of a pump body, and realizes the recycling of the polishing liquid by setting up a self-cleaning conveying mechanism.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the specification 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.

[0034] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a bearing inner ring grinding device suitable for textile machinery, including a mounting base plate 1, a support seat 10 is fixedly connected to one side of the top of the mounting base plate 1, a rotating cylinder 701 is mounted on the outer side of the support seat 10, a plurality of jacks 704 are provided on the inner side of the rotating cylinder 701, a moving block 705 is slidably connected to the inner wall of the rotating cylinder 701, a screw rod 706 is threadedly connected to the outer through hole of the moving block 705, a driving plate 707 is threadedly connected to the outer side of the screw rod 706, a rotating rod 708 is rotatably connected to the outer side of the driving plate 707, and the rotating cylinder 701 is rotated to rotate. One end of the movable rod 708 is rotatably connected to the plug rod 709, and the longitudinal section of the plug rod 709 is set to be square. One end of the plug rod 709 is plugged into the socket 704. The outer wall of the rotating cylinder 701 and the outer side of the moving block 705 are rotatably connected to the hinged rod 703, and one end of the hinged rod 703 is rotatably connected to the grinding disc 702. A dust reduction assembly is arranged on the outside of the support seat 10, and a driving assembly is installed on the top of the support seat 10, and the driving assembly is used to drive the dust reduction assembly. A clamping assembly is installed on the top of the mounting base 1, and the clamping assembly is used to clamp the bearing to be processed.

[0035] Specifically, the device uses the electric guide rail 4 and the electric slider 5 to accurately extend the grinding disc 702 into the inner side of the bearing inner ring. The electric slider 5 drives the grinding disc 702 to make fine adjustments in a fixed position to adapt to the bearing inner rings of different sizes and shapes. When the device starts working, the moving block 705 is first moved upward or downward to drive the hinge rod 703 to swing, thereby pushing the grinding disc 702 to the inner wall of the bearing inner ring. With the movement of the moving block 705, the hinge rod 703 generates a torque to push the grinding disc 702 to gradually fit the bearing inner ring.

[0036] At this time, by rotating the screw rod 706, the driving plate 707 moves along the screw rod 706. The driving plate 707 drives the rotating rod 708 to swing, and the insertion rod 709 on the rotating rod 708 is inserted into the insertion hole 704 to fix the grinding disc 702, so that it maintains a stable contact state with the inner ring of the bearing.

[0037] During the grinding process, the grinding disc 702 swings and slides in the rotating cylinder 701 to achieve uniform grinding of the inner ring. The device can accurately control the grinding disc 702 and the grinding angle by adjusting the combination of the screw rod 706 and the moving block 705, thereby ensuring the smoothness and accuracy of the inner wall of the bearing inner ring.

[0038] The driving assembly includes an electric guide rail 4 installed on the outside of two support seats 10, an electric slider 5 is installed on the outside of the electric guide rail 4, a mounting plate 601 is installed on the outside of the electric slider 5, a dual-axis servo motor 602 is installed on the bottom of the mounting plate 601, a fixed disk 603 is fixedly connected to the top output end of the dual-axis servo motor 602, a fixed block 604 is fixedly connected to the eccentric part of the outside of the fixed disk 603, a movable plate 605 is slidably connected to the outer surface of the fixed disk 603, and a movable groove 606 is arranged inside the movable plate 605; guide rods 9 are slidably connected to the two through holes on the inner side of the movable plate 605, one end of the guide rod 9 is fixedly connected to the outer side of the mounting plate 601, and the fixed block 604 is movably connected to the inner wall of the movable groove 606;

[0039] The dust suppression assembly includes a fixed box 803 and a fixed cylinder 801, the fixed cylinder 801 is fixedly connected to the top of the guide rod 9, the fixed box 803 is fixedly connected to the outside of the support seat 10, the interior of the fixed cylinder 801 is slidably connected to a movable plate 807, the outside of the movable plate 807 is fixedly connected to a movable rod 806, the outside of the fixed cylinder 801 is connected to an air inlet pipe 808, the top of the fixed cylinder 801 is connected to a first connecting pipe 802, and the bottom of the fixed box 803 is connected to two second connecting pipes. Tube 804, one end of the second connecting tube 804 is connected to the dust removal tube 805; the top of the first connecting tube 802 is connected to the top of the fixed box 803, and the inner side of the fixed box 803 is detachably connected with a blocking net, the dust removal tube 805 is fixedly connected to the top of the mounting base 1, and the end of the movable rod 806 away from the fixed cylinder 801 is fixedly connected to the outer side of the movable plate 605; both the first connecting tube 802 and the air inlet pipe 808 are installed with a one-way valve on the inner side, and the flow directions of the one-way valve are opposite.

[0040] Specifically, the fixed box 803 is connected to the dust removal pipe 805 through the second connecting pipe 804, and one end of the second connecting pipe 804 is connected to the mounting base plate 1 through the dust removal pipe 805, which is used to guide the dust into the fixed box 803 and carry out centralized treatment. A barrier net is provided in the fixed box 803 to filter out larger particles and ensure that the dust will not be blocked when entering the accommodating part. A one-way valve is provided in both the fixed cylinder 801 and the air inlet pipe 808, and the flow directions of the one-way valve are opposite. This design can realize the flow direction control of different airflows, thereby effectively improving the negative pressure effect. The design of the air inlet pipe 808 enables the fixed cylinder 801 to be connected to the fixed box 803, helping the negative pressure airflow in the fixed cylinder 801 to effectively absorb the dust in the external environment and introduce it into the fixed box 803.

[0041] During the working process, the movable plate 807 is driven to slide up and down along the inner wall of the fixed cylinder 801 through the repeated movement of the movable rod 806. As the movable plate 807 moves, the air in the fixed cylinder 801 is quickly sucked in and negative pressure is generated. Since the fixed cylinder 801 is interconnected with the fixed box 803 through the air inlet pipe 808, this negative pressure will act on the inside of the dust removal pipe 805, thereby adsorbing the dust generated during the grinding process and introducing it into the fixed box 803. After the dust enters the fixed box 803 through the dust removal pipe 805, the barrier net in the fixed box 803 will preliminarily screen and filter the larger dust particles. The filtered dust is stored in the fixed box 803 and can be cleaned and disposed of after processing, thereby avoiding secondary pollution of the dust.

[0042] The clamping assembly includes a first cylinder 301, which is fixedly connected to one side of the top of the mounting base plate 1, and the output end of the first cylinder 301 is fixedly connected to a moving plate 302, the outer side of the moving plate 302 is rotatably connected to a swing rod 303, and one end of the swing rod 303 is rotatably connected to an arc-shaped clamping plate 304.

[0043] Specifically, due to the connection between the swing rod 303 and the cylinder output end moving plate 302 and the arc clamping plate 304, when the cylinder pushes the output end moving plate 302, the swing rod 303 swings and pulls the arc clamping plate 304 connected to the other end. At the same time, the arc clamping plate 304 swings accordingly along its rotation axis, thereby completing the clamping action of the bearing inner ring. The swinging arc clamping plate 304 can be in close contact with the surface of the bearing inner ring, and the bearing inner ring is evenly clamped by its bending shape. The design of the arc clamping plate 304 can adapt to bearing inner rings of different sizes and shapes, ensuring the stability and accuracy of clamping.

[0044] Since the air pressure of the first cylinder 301 is adjustable, the clamping assembly can adjust the clamping force according to actual conditions to ensure that the inner ring of the bearing does not loosen or move during the grinding process, and the inner ring of the bearing will not be damaged due to over-tightening.

[0045] The entire clamping process is completed by the pneumatic drive system, which does not require manual intervention, can improve production efficiency and reduce human operation errors. The pneumatic system can also be combined with other automatic control systems (such as PLC control) to achieve automatic adjustment and monitoring to meet the needs of large-scale production.

[0046] A collecting box 201 is fixedly connected to one side of the bottom end of the installation base plate 1, a magnet for attracting impurities is installed on the top of the collecting box 201, a filter screen 202 is detachably connected to the inside of the collecting box 201, a pump body 204 is installed on the outside of the collecting box 201, a second connecting pipe 205 is fixedly connected to the output end of the pump body 204, a liquid spraying pipe 206 is installed at the end of the second connecting pipe 205, and a first connecting pipe 203 is fixedly connected to the input end of the pump body 204. One end of the first connecting pipe 203 is connected to the outside of the collecting box 201, and polishing liquid is arranged inside the collecting box 201.

[0047] Specifically, the impurity-absorbing electromagnet is installed on the top of the collecting box 201 to absorb the metal impurities in the polishing liquid. The impurity-absorbing electromagnet generates a magnetic field when powered on, effectively absorbing the metal particles in the polishing liquid.

[0048] When the equipment is started, the pump body 204 starts to work, and the polishing liquid in the collection box 201 is sucked into the second connecting pipe 205 of the pump body 204 through the first connecting pipe 203, and further transported to the spray pipe 206. The end of the spray pipe 206 opens outward, and a uniform spray flow is formed after spraying. The polishing liquid is sprayed on the surface of the inner ring of the bearing to be processed for grinding and polishing operations. During the grinding process, impurities and metal chips in the polishing liquid are generated during grinding and fall into the collection box 201. At this time, the impurity absorption electromagnet is energized to generate a magnetic field to absorb metal impurities in the polishing liquid to improve the cleanliness of the polishing liquid and prevent impurities from contaminating the polishing surface again. The sprayed polishing liquid flows on the surface of the filter screen 202 and is filtered through the filter screen 202. The filtered liquid flows back to the collection box 201. In this way, the polishing liquid can maintain good performance after repeated use while reducing waste. After the polishing liquid is filtered through the filter screen 202, the liquid will return to the bottom of the collection box 201, and the impurity absorption electromagnet will separate the adsorbed metal impurities through electromagnetic force to prevent the impurities from entering the liquid again, thereby ensuring the cleanliness and efficient recycling of the polishing liquid.

[0049] A method for using a bearing inner ring grinding device suitable for textile machinery comprises the following steps:

[0050] Step 1: Place the bearing to be processed on the top of the mounting base plate 1, and then start the first cylinder 301 to drive the moving plate 302 to move, and then swing the swing rod 303, and drive the arc clamping plate 304 to swing under the traction of the swing rod 303, and use the arc clamping plate 304 to clamp the inner ring of the bearing;

[0051] Step 2, after clamping the bearing, cooperate with the electric guide rail 4 and the electric slider 5 to extend the grinding disc 702 into the inner side of the inner ring of the bearing. At this time, by moving the moving block 705 upward or downward, the hinge rod 703 is driven to swing, and the grinding disc 702 is driven to move outward under the traction force of the hinge rod 703 until the grinding disc 702 can be closely contacted with the inner wall of the inner ring of the bearing. At this time, the driving plate 707 is moved left and right along the outer wall of the screw rod 706 by rotating the screw rod 706. At this time, as the driving plate 707 moves, one end of the rotating rod 708 is driven to swing. Under the traction force of the rotating rod 708, one end of the plug rod 709 is stuck in the socket 704 to ensure the fixed position of the grinding disc 702;

[0052] Step 3: When the dual-axis servo motor 602 is started, it drives the driving assembly to work, and drives the movable rod 806 to move repeatedly through the driving assembly, and then drives the movable plate 807 to move repeatedly along the inner wall of the fixed cylinder 801, so that the interior of the fixed cylinder 801 is constantly in a negative pressure state. Since the fixed cylinder 801 is connected to the fixed box 803 through the air inlet pipe 808, a negative pressure state is generated inside the dust removal pipe 805, and the dust generated during the grinding of the inner ring of the bearing is absorbed into the interior of the fixed box 803;

[0053] Step 4: Start the pump body 204 to transport the polishing liquid in the collection box 201 into the spray pipe 206 through the first connecting pipe 203 and the second connecting pipe 205, and discharge it through the spray pipe 206. The discharged polishing liquid flows on the outer surface of the filter 202 and flows back to the collection box 201. At this time, the impurity absorption electromagnet is energized to generate magnetism to absorb metal impurities in the polishing liquid, thereby ensuring the recovery efficiency of the polishing liquid.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

7. The bearing inner ring grinding device suitable for textile machinery according to claim 6, characterized in that: One end of the first connecting tube (203) is in communication with the outside of the collecting box (201), and polishing liquid is provided inside the collecting box (201).

8. A method for using a bearing inner ring grinding device suitable for textile machinery, according to the bearing inner ring grinding device suitable for textile machinery according to claim 7, characterized in that: The following steps are involved: Step 1: Place the bearing to be processed on the top of the mounting base plate (1), and then start the first cylinder (301) to drive the moving plate (302) to move, and then swing the swing rod (303), and drive the arc clamping plate (304) to swing under the traction force of the swing rod (303), and use the arc clamping plate (304) to clamp the inner ring of the bearing; Step 2: After clamping the bearing, cooperate with the electric guide rail (4) and the electric slider (5) to extend the grinding disc (702) into the inner side of the inner ring of the bearing. At this time, by moving the moving block (705) upward or downward, the hinged rod (703) is driven to swing, and the grinding disc (702) is driven to move outward under the action of the traction force of the hinged rod (703) until the grinding disc (702) can be closely contacted with the inner wall of the inner ring of the bearing. At this time, by rotating the screw rod (706), the driving plate (707) is moved left and right along the outer wall of the screw rod (706). At this time, as the driving plate (707) moves, one end of the rotating rod (708) is driven to swing. Under the action of the traction force of the rotating rod (708), one end of the plug rod (709) is inserted into the plug hole (704) to ensure the fixed position of the grinding disc (702); Step 3: When the dual-axis servo motor (602) is started, it drives the driving assembly to work, and the driving assembly drives the movable rod (806) to move repeatedly, and then drives the movable plate (807) to move repeatedly along the inner wall of the fixed cylinder (801), so that a negative pressure state is continuously formed inside the fixed cylinder (801). Since the fixed cylinder (801) is connected to the fixed box (803) through the air inlet pipe (808), a negative pressure state is generated inside the dust removal pipe (805), and the dust generated during the grinding of the inner ring of the bearing is absorbed into the interior of the fixed box (803); Step 4: Start the pump body (204) to transport the polishing liquid in the collection box (201) through the first connecting pipe (203) and the second connecting pipe (205) into the interior of the liquid spray pipe (206), and discharge it through the liquid spray pipe (206). The discharged polishing liquid flows on the outer surface of the filter (202) and flows back to the interior of the collection box (201). At this time, the impurity absorption electromagnet is energized to generate magnetism to absorb metal impurities in the polishing liquid, thereby ensuring the recovery effect of the polishing liquid.
