Description

Technical Field

[0001] This invention relates to the field of bearing ring machining technology, and more specifically, to a bearing ring machining equipment. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. Special attention must be paid to the installation sequence when installing bearing rings. For precision bearings, the correct and reverse ends must also be considered. Reversing the installation will cause dynamic imbalance and affect the bearing performance. The axial positioning of ultra-precision angular contact ball bearings on the shaft or in the bearing housing is usually achieved by locking nuts or end caps. These components require high geometric accuracy and good mechanical strength to provide stable support and positioning. The tightening torque of the precision locking nuts or end cap bolts must be large enough to ensure that all components are positioned without deformation or damage.

[0003] Bearing rings are generally formed in the following ways: forging, turning, cold rolling, and cold (warm) extrusion. Forging, a common process for precision machine tool bearings, eliminates inherent defects in the metal, improves its structure, and ensures efficient flow and high density. Forging is widely used in rolling bearing forming. Common forging methods include hot forging, cold forging, and warm forging. Stamping is an advanced process that improves material utilization, enhances metal density, and maintains streamlined shape; it is a chip-free machining method. When using stamping dies and forging processes, the precision of new products is affected not only by the precision of the machine equipment but also by the precision of the forming dies. Traditional turning technology uses specialized CNC lathes and a centralized process flow for forming.

[0004] In practice, machining bearing rings using machine tools is a particularly important machining method for bearing rings. Existing machine tools use a guide cabinet to feed the bearing rings one by one onto the machine tool, and then use a cutting head to machine the rotating bearing rings. However, since the bearing rings need to be machined one by one, the processing time is relatively long, which affects the machining efficiency of the machine tool and further reduces the production efficiency of the machine tool.

[0005] Therefore, we propose a bearing ring machining equipment to solve the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a bearing ring machining equipment to solve the problems mentioned in the background art.

[0013] In this device, the bearing rings in the guide rail first fall directly onto the upper support roller. At this point, the controller activates the second electric telescopic rod, allowing the bearing rings to enter the fixed seat. Then, with the assistance of the electric slide rail, the support roller moves accordingly. The controller then moves the cutting head, allowing the bearing rings to be processed. Once the bearing rings are processed into semi-finished products, the cutting head retracts, and the electric slide rail operates again. This time, the first electric telescopic rod activates, causing the bearing rings to fall out. Then, the servo motor activates, allowing the bearing rings to fall onto the lower support roller. At this point, the bearing rings in the guide rail... The bearing rings can fall directly onto the upper support roller. Then, the controller activates the second electric telescopic rod. When the second electric telescopic rod is working, the baffle moves, allowing the bearing rings to enter the fixed seat. The controller then moves the cutting head, allowing the bearing rings to be processed. The upper bearing rings can be processed into semi-finished products, while the lower bearing rings can be processed into complete products. This allows the device to pre-process the bearing rings simultaneously, reducing the processing time and further improving the production efficiency and practicality of the device.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1-11 A bearing ring machining equipment includes a worktable 1, on which a guide channel is provided, and the guide channel is inclined downward. It is particularly noteworthy that a nozzle is connected to the worktable 1, and the nozzle is connected to an external air pump, thereby achieving the purpose of cleaning the worktable 1. At the same time, the nozzle is also located in the guide channel, thereby achieving the purpose of cleaning the guide channel, and further enabling the bearing ring to be discharged normally.

[0038] Meanwhile, a first drive box 2 is fixedly connected to the worktable 1, and the first drive box 2 is equipped with multiple linear guide rails. These multiple linear guide rails enable the two cutting heads 7 to move left, right, up, down, forward, and backward, thereby enabling the processing of bearing rings. It is particularly noteworthy that the cutting heads 7 are located on one side of the two fixed seats 16, which allows for the processing of bearing rings.

[0039] It is also worth noting that the upper end of the workbench 1 is fixedly connected to the second drive box 3, and a guide rail is provided on one side of the second drive box 3. The guide rail is inclined downward and is located above the fixed seat 16. At the same time, a feeding rail is connected to one side of the guide rail. The operator can place the bearing ring into the feeding rail, and with the assistance of the guide rail, the bearing ring can enter the side of the fixed seat 16, thereby completing the processing of the bearing ring.

[0040] Meanwhile, a drive motor 4 is fixedly connected to the side wall of the second drive box 3, and a rotating shaft 8 is fixedly connected to the drive shaft of the drive motor 4. Two first pulleys 9 are fixedly connected to the side wall of the rotating shaft 8, and the two first pulleys 9 are respectively connected to the two second pulleys 13 through belts 10.

[0041] Furthermore, two bearing seats 11 are fixedly connected to the side wall of the second drive box 3, and a rotating rod 12 is provided through each of the two bearing seats 11. One end of the rotating rod 12 passes through the side wall of the second drive box 3 and extends to the outside. At the same time, two second pulleys 13 are respectively sleeved on the two rotating rods 12. Therefore, when the drive motor 4 works, the two first pulleys 9 can rotate accordingly. With the assistance of the belt 10, the two second pulleys 13 can rotate accordingly, thereby causing the two rotating rods 12 to rotate. In this way, the two rotating seats 5 can rotate accordingly.

[0042] Multiple fixing rods 15 are fixedly connected to the side walls of both rotating seats 5. One end of each fixing rod 15 is fixedly connected to a fixing seat 16. There are two fixing seats 16, which are arranged vertically. A push plate 17 is provided inside the fixing seat 16. Both rotating seats 5 are provided with a first electric telescopic rod 14. One end of each first electric telescopic rod 14 is fixedly connected to the side wall of the two push plates 17. After the bearing ring is processed, when the two first electric telescopic rods 14 are working, the two push plates 17 can be moved forward, which in turn allows the bearing ring to move out of the fixing seat 16.

[0043] Meanwhile, with the assistance of the baffle 31, the bearing ring can enter the fixed seat 16. When the rotating seat 5 rotates, the fixed seat 16 will also rotate, so that the bearing ring can rotate. With the assistance of the cutting head 7, the bearing ring can be processed. The way the fixed seat 16 fixes the bearing ring is the same as the existing technology, which will not be described in detail here.

[0044] Meanwhile, two electric slide rails 18 are fixedly connected to the side wall of the second drive box 3. The two electric slide rails 18 are located on both sides of the rotating seat 5. Each of the two electric slide rails 18 is slidably connected to a matching electric slider 19. Each of the two electric sliders 19 is fixedly connected to a connecting rod 20. It is worth noting that both connecting rods 20 are bent, and one end of each connecting rod 20 extends to one side of the fixed seat 16. At the same time, a bent rod 21 is fixedly connected to the connecting rod 20, and one end of the bent rod 21 extends to the bottom of the connecting rod 20. It is worth noting that there are two fixed seats 16, which are arranged one above the other. The two connecting rods 20 are located on both sides of the upper fixed seat 16, and the bent rods 21 are located on both sides of the lower fixed seat 16, thereby serving to limit the bearing rings.

[0045] Meanwhile, one end of each of the two connecting rods 20 and the two bending rods 21 is connected to the drive cylinder 6. There are four drive cylinders 6, two of which are located on one side of the upper fixed seat 16, and the other two are located on one side of the lower fixed seat 16.

[0046] Meanwhile, a servo motor 22 is fixedly connected to the inner wall of the drive cylinder 6, and a rotating rod 23 is fixedly connected to the drive shaft of the servo motor 22. A connecting plate 24 is fixedly connected to one end of the rotating rod 23, and a support roller 25 is fixedly connected to one end of the connecting plate 24. It is particularly noteworthy that since the drive cylinder 6 is located on one side of the fixed seat 16, and since the connecting plate 24 is inclined, the support roller 25 is located on one side of the drive cylinder 6. It is also particularly noteworthy that the distance between the two drive cylinders 6 is larger than the distance between the two support rollers 25, so as to support the bearing ring. Furthermore, a rotatable rubber sleeve is fitted on the support roller 25 to protect the support roller 25, and the rotation of the rubber sleeve allows the bearing ring to be positioned better.

[0047] Meanwhile, a fixing plate 26 is fixedly connected to the side wall of the second drive box 3, and a second electric telescopic rod 27 is fixedly connected to the side wall of the fixing plate 26. A bending rod 28 is fixedly connected to one end of the second electric telescopic rod 27, and one end of the bending rod 28 extends to the front of the two fixing seats 16. At the same time, a baffle 31 is fixedly connected to one end of the bending rod 28, and the baffle 31 is located directly in front of the two fixing seats 16. It is worth noting that the bending rod 28 does not affect the normal use of the connecting rod 20 and the bending rod 21.

[0048] Two crossbars 29 are fixedly connected to the side wall of the second drive box 3, and one end of the two crossbars 29 is fixedly connected to the same limiting plate 30. It is particularly noteworthy that the upper and lower ends of the limiting plate 30 are provided with notches that match the fixed seats 16. At the same time, the limiting plate 30 is located between the two fixed seats 16, and the cooperation between the limiting plate 30 and the baffle 31 can limit the bearing ring after it is pushed out and falls from the upper fixed seat 16, further preventing the bearing ring from falling out, so that the bearing ring can fall normally onto the lower support roller 25, and further enable the bearing ring to be processed normally.

[0049] In this invention, when the operator uses this device, the bearing ring in the guide rail first falls directly onto the upper support roller 25. At this time, the controller activates the second electric telescopic rod 27. When the second electric telescopic rod 27 is working, the baffle 31 moves, allowing the bearing ring to enter the fixed seat 16. Then, with the assistance of the electric slide rail 18, the support roller 25 moves. The controller then moves the cutting head 7, allowing the bearing ring to be processed. After the bearing ring is processed into a semi-finished product, the cutting head retracts, and the electric slide rail 18 operates again, positioning the support roller 25 on one side of the fixed seat 16. At this time, the first electric telescopic rod 14 operates, causing the bearing ring to fall out. Then, the servo motor 22 operates, changing the angle of the support roller 25, allowing the bearing ring to fall onto the lower support roller 25. At this point, the guide rail... The bearing rings in the track can fall directly onto the upper support roller 25. Then the controller activates the second electric telescopic rod 27. When the second electric telescopic rod 27 is working, the baffle 31 can be moved, allowing the bearing rings to enter the fixed seat 16. Then the controller moves the cutting head 7, allowing the bearing rings to be processed. The upper bearing rings can be processed into semi-finished products again, while the lower bearing rings can be processed into complete products. Then the lower first electric telescopic rod 14 and servo motor 22 work, allowing the lower bearing rings to move out of the fixed seat 16 and fall to the outside for further processing. Then the upper first electric telescopic rod 14 works, allowing the upper bearing rings to fall onto the lower support roller 25, thus allowing the semi-finished bearing rings to be processed again.
