Description

Technical Field

[0001] The present invention relates to the technical field of bearing detection equipment, and particularly to an automatic detection device for the outer ring of a shield machine bearing. Background Art

[0002] In the production process of the outer ring of a bearing, in order to control the quality of the bearing, it is usually necessary to detect the flatness, diameter, etc. of the outer ring of the bearing to detect whether the bearing is deformed. In a shield machine, due to the high axial assembly accuracy and the need to meet specific load-bearing requirements, it is necessary to adjust the outer diameter of the bearing while keeping the width unchanged. For example, when the shield machine needs to bear a greater radial load, a bearing with a slightly larger outer diameter will be selected to increase the load-bearing capacity.

[0003] Most shield machine bearings use three-row cylindrical roller bearings. When producing three-row cylindrical roller bearings, due to different usage ranges, the corresponding outer diameters are also different. Most of the existing detection devices for three-row cylindrical roller bearings are designed to detect bearings with a specified outer diameter. Since the outer diameters of three-row cylindrical roller bearings are different, when facing three-row cylindrical roller bearings with different outer diameters, it is necessary to replace different detection devices or manually adjust the position of the detector, which increases the workload of detection, results in low detection efficiency, and complicates the detection work. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic detection device for the outer ring of a shield machine bearing to solve the problem that most shield machine bearings use three-row cylindrical roller bearings. When producing three-row cylindrical roller bearings, due to different usage ranges, the corresponding outer diameters are also different. Most of the existing detection devices for three-row cylindrical roller bearings are designed to detect bearings with a specified outer diameter. Since the outer diameters of three-row cylindrical roller bearings are different, when facing three-row cylindrical roller bearings with different outer diameters, it is necessary to replace different detection devices or manually adjust the position of the detector, which increases the workload of detection, results in low detection efficiency, and complicates the detection work.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is an automatic detection device for the outer ring of a shield machine bearing, including an annular plate. A cross-shaped connecting plate is fixedly installed inside the annular plate. A plurality of limit blocks are slidably installed through the cross-shaped connecting plate.

It is characterized in that it further includes: A plurality of adjusting mechanisms, the adjusting mechanism includes a triangular plate, an adjusting component, the triangular plate is used to drive the adjusting component to move, and a pushing component, the triangular plate is used to drive the pushing component to slide; The adjusting component includes a special-shaped plate slidably mounted in the limiting groove.

A U-shaped round rod is fixedly mounted on the side wall of the cross connecting plate, and the U-shaped round rod is in contact with the triangular plate.

[0006] Further, rectangular limiting rods are respectively and fixedly mounted in several limiting grooves. The several rectangular limiting rods respectively penetrate through several special-shaped plates and are respectively slidably connected with the several special-shaped plates. Adjusting springs are respectively sleeved on the several rectangular limiting rods. One ends of the several adjusting springs away from each other are respectively fixedly connected with the limiting grooves, and one ends of the several adjusting springs close to each other are respectively fixedly connected with the several special-shaped plates.

[0007] Further, rotating rods are respectively rotatably mounted on the tops of several limiting blocks, and rollers are respectively and fixedly sleeved on the several rotating rods.

[0008] Further, connecting rods are respectively fixedly mounted on the bottoms of several limiting blocks. The bottoms of the several connecting rods are fixedly mounted with a circular plate, and a push rod is fixedly mounted on the bottom of the circular plate.

[0009] Further, a transmission mechanism is arranged below the annular plate. The transmission mechanism includes a transmission hydraulic tank arranged below the annular plate. Two fixing plates are fixedly mounted on the bottom of the annular plate, and the bottom ends of the two fixing plates are both fixedly connected with the transmission hydraulic tank. The bottom end of the push rod extends into the transmission hydraulic tank and is slidably connected with the transmission hydraulic tank. A transmission circular plate is fixedly mounted on the bottom end of the push rod.

[0010] Further, several transmission strip boxes are fixedly mounted on the outer wall of the transmission hydraulic tank. U-shaped round tubes are respectively fixedly mounted on the tops of the several transmission strip boxes, and the several transmission strip boxes are all communicated with the transmission hydraulic tank.

[0011] Further, a driving motor is fixedly mounted in the cross connecting plate. A hollow tube is fixedly mounted on the output shaft of the driving motor. An annular hollow box is rotatably sleeved on the outer wall of the hollow tube. Several through grooves are formed in the hollow tube, and the several through grooves are all communicated with the annular hollow box.

[0012] Further, several fixing mechanisms are arranged on the hollow tube. The fixing mechanism includes a connecting box fixedly mounted on the hollow tube. A rectangular hollow tube is fixedly mounted on the front of the connecting box, and an L-shaped limiting block is fixedly mounted in the rectangular hollow tube.

[0013] Further, a number of rectangular partitions are fixedly installed inside the rectangular hollow tube, an adaptation spring is fixedly installed on the front surfaces of the number of rectangular partitions, and the front end of the adaptation spring is fixedly connected to an L-shaped limit block.

[0014] Further, a rectangular installation groove is formed in the front surface of the L-shaped limit block, a rotating round rod is rotatably installed in the rectangular installation groove, a rubber block is fixedly sleeved on the rotating round rod, and a number of rubber bumps are fixedly installed on the front surface of the rubber block.

[0015] The present invention has the following beneficial effects: (1) For the automatic detection device for the outer ring of a shield machine bearing of the present invention, when in use, first place the bearing to be detected on the roller from top to bottom. After the gripper is released when the bearing lands on the roller, the bearing will evenly land on the roller. At this time, the roller will descend due to the gravity of the bearing, the roller will drive the limit block to descend, the limit block will drive the rectangular limit rod to descend, the rectangular limit rod will drive the special-shaped plate to descend, and the special-shaped plate will drive the triangular plate to descend. During the descent of the triangular plate, it will contact the U-shaped round rod, and the U-shaped round rod will cause the triangular plate to move away from the U-shaped round rod under the action of the inclined surface of the triangular plate. At this time, the triangular plate will drive the special-shaped plate to move synchronously. The larger the size of the bearing, the greater its gravitational potential energy, and correspondingly, the triangular plate will be farther away from the U-shaped round rod. When the triangular plate stops moving, the corresponding special-shaped plate will also stop moving. When the special-shaped plate moves, it will drive the installation plate to move, and the installation plate will drive the intelligent sensor to move synchronously. Since the material of the bearing is high-carbon chromium bearing steel, the intelligent sensor will make corresponding adjustments according to the size and weight of the bearing to ensure an effective detection distance between the intelligent sensor and the outer ring of the bearing, improving the applicable range and flexibility of the device and enabling effective detection of bearings of different sizes. (2) In the automatic detection device for the outer ring of the shield machine bearing of the present invention, during the descent of the limit block, the connecting rod will be driven to descend. The connecting rod will drive the circular plate to descend. The circular plate will drive the push rod to descend. The push rod will drive the transmission circular plate to descend. The transmission circular plate will push the liquid in the transmission hydraulic tank to descend. At this time, the liquid in the transmission hydraulic tank will flow into the transmission strip box. The liquid will enter the U-shaped circular tube from the transmission strip box. The liquid will enter the annular hollow box from the U-shaped circular tube. Then the liquid will enter the hollow tube from the through groove. Since the larger the size of the bearing, the greater its mass, and when the mass of the bearing is greater, the distance that the transmission circular plate descends will be greater, and more liquid in the transmission hydraulic tank will flow into the hollow tube. Due to the increase in the hydraulic pressure in the hollow tube, the liquid will enter the rectangular hollow tube along the gaps between several rectangular partitions. The liquid will push the L-shaped limit block to move away from the hollow tube. At this time, the adaptation spring will undergo corresponding tensile deformation. The L-shaped limit block will drive the rotating round rod to move. The rotating round rod will drive the rubber block to top against the inner ring of the bearing, supporting and fixing the bearing to ensure that the bearing remains stable during detection and prevent the bearing from shaking during detection, resulting in detection errors. (3) In the automatic detection device for the outer ring of the shield machine bearing of the present invention, after the bearing is fixed, the drive motor is started. The drive motor drives the hollow tube to rotate. The hollow tube drives several connecting boxes to rotate. The connecting boxes drive the rectangular hollow tube to rotate. The rectangular hollow tube drives several L-shaped limit blocks to rotate. The L-shaped limit blocks drive the rotating round rods to rotate. The rotating round rods drive the rubber blocks to rotate. The rubber blocks will drive the bearing to rotate under the action of friction. Since the rotating rod can rotate, the roller will also rotate during the rotation of the bearing, which can effectively reduce the friction between the bearing and the roller and make the bearing rotate more smoothly. If the rubber block does not fit tightly with the inner ring of the bearing, the rubber convex block will increase the friction between the rubber block and the bearing. When the L-shaped limit block rotates, the corresponding rubber block will cause the rotating round rod to rotate at the contact with the inner ring of the bearing, resulting in a slight angular offset of the rubber block. The angular offset of the rubber block will increase the friction between the rubber block and the inner ring of the bearing, ensuring that the rubber block can drive the bearing to rotate more effectively when rotating and ensuring that the intelligent sensor can stably conduct a comprehensive detection of the outer ring of the bearing.

[0016] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figures 1 - 8As shown in the figure, the present invention is an automatic detection device for the outer ring of a shield machine bearing, including an annular plate 1, a cross connecting plate 2 fixedly installed inside the annular plate 1, a number of limiting blocks 3 slidably installed through the cross connecting plate 2, and limiting grooves 4 respectively opened on the number of limiting blocks 3. It is characterized in that it further includes: A number of adjusting mechanisms 5, the adjusting mechanism 5 includes a triangular plate 504, an adjusting component, the triangular plate 504 is used to drive the adjusting component to move, a pushing component, and the triangular plate 504 is used to drive the pushing component to slide; The adjusting component includes a special-shaped plate 501 slidably installed in the limiting groove 4, an installation plate 502 fixedly installed on the top of the special-shaped plate 501, and an intelligent sensor 503 fixedly installed on the back of the installation plate 502; The pushing component includes a triangular plate 504 fixedly installed at the bottom of the special-shaped plate 501, and a U-shaped round rod 505 fixedly installed on the side wall of the cross connecting plate 2, and the U-shaped round rod 505 is in contact with the triangular plate 504.

[0022] As Figure 4 shown, rectangular limiting rods 506 are respectively fixedly installed in a number of limiting grooves 4, the number of rectangular limiting rods 506 respectively penetrate through the number of special-shaped plates 501 and are respectively slidably connected with the number of special-shaped plates 501, adjusting springs 507 are respectively sleeved on the number of rectangular limiting rods 506, one end of the number of adjusting springs 507 away from each other is respectively fixedly connected with the limiting groove 4, and one end of the number of adjusting springs 507 close to each other is respectively fixedly connected with the number of special-shaped plates 501.

[0023] The limiting block 3 will drive the rectangular limiting rod 506 to descend, the rectangular limiting rod 506 will drive the special-shaped plate 501 to descend, the special-shaped plate 501 will drive the triangular plate 504 to descend, and the triangular plate 504 will contact the U-shaped round rod 505 during the descending process, and the U-shaped round rod 505 will move the triangular plate 504 away from the U-shaped round rod 505 under the action of the inclined surface of the triangular plate 504.

[0024] As Figure 4 shown, rotating rods 508 are respectively rotatably installed on the tops of the number of limiting blocks 3, and rollers 509 are respectively fixedly sleeved on the number of rotating rods 508.

[0025] Since the rotating rod 508 can rotate, the roller 509 will also rotate during the rotation of the bearing, which can effectively reduce the friction between the bearing and the roller 509 and make the bearing rotate more smoothly.

[0026] As Figure 4 shown, connecting rods 510 are respectively fixedly installed at the bottoms of the number of limiting blocks 3, circular plates 511 are fixedly installed at the bottoms of the number of connecting rods 510, and push rods 512 are fixedly installed at the bottoms of the circular plates 511.

[0027] During the downward movement of the limit block 3, the connecting rod 510 will be driven downward. The connecting rod 510 will drive the circular plate 511 downward. The circular plate 511 will drive the push rod 512 downward. The push rod 512 will drive the transmission circular plate 603 downward.

[0028] As Figure 1 and Figure 5 shown, a transmission mechanism 6 is provided below the annular plate 1. The transmission mechanism 6 includes a transmission hydraulic tank 601 provided below the annular plate 1. Two fixing plates 602 are fixedly installed at the bottom of the annular plate 1. The bottom ends of the two fixing plates 602 are fixedly connected to the transmission hydraulic tank 601. The bottom end of the push rod 512 extends into the transmission hydraulic tank 601 and is slidably connected to the transmission hydraulic tank 601. A transmission circular plate 603 is fixedly installed at the bottom end of the push rod 512.

[0029] The push rod 512 will drive the transmission circular plate 603 downward. The transmission circular plate 603 will push the liquid in the transmission hydraulic tank 601 downward.

[0030] As Figure 5 shown, a plurality of transmission strip boxes 604 are fixedly installed on the outer wall of the transmission hydraulic tank 601. The top parts of the plurality of transmission strip boxes 604 are respectively fixedly installed with U-shaped circular tubes 605. The plurality of transmission strip boxes 604 are all communicated with the transmission hydraulic tank 601.

[0031] The liquid in the transmission hydraulic tank 601 will flow into the transmission strip box 604, and the liquid will enter the U-shaped circular tube 605 from the transmission strip box 604.

[0032] As Figure 7 shown, a drive motor 606 is fixedly installed in the cross connecting plate 2. A hollow tube 607 is fixedly installed on the output shaft of the drive motor 606. An annular hollow box 608 is rotatably sleeved on the outer wall of the hollow tube 607. A plurality of through grooves 609 are formed in the hollow tube 607. The plurality of through grooves 609 are all communicated with the annular hollow box 608.

[0033] The liquid will enter the annular hollow box 608 from the U-shaped circular tube 605, and then the liquid will enter the hollow tube 607 from the through groove 609. Since the larger the size of the bearing, the greater its mass, and when the mass of the bearing is greater, the distance that the transmission circular plate 603 descends will be greater, and more liquid in the transmission hydraulic tank 601 will flow into the hollow tube 607. Due to the increase in the hydraulic pressure in the hollow tube 607.

[0034] As Figure 7 shown, a plurality of fixing mechanisms 7 are provided on the hollow tube 607. The fixing mechanism 7 includes a connecting box 701 fixedly installed on the hollow tube 607. A rectangular hollow tube 702 is fixedly installed on the front surface of the connecting box 701. An L-shaped limit block 703 is fixedly installed in the rectangular hollow tube 702.

[0035] The hollow tube 607 drives several connecting boxes 701 to rotate. The connecting boxes 701 drive the rectangular hollow tube 702 to rotate, and the rectangular hollow tube 702 drives several L-shaped limiting blocks 703 to rotate.

[0036] As Figure 7 shown, several rectangular partitions 704 are fixedly installed inside the rectangular hollow tube 702. An adaptation spring 705 is fixedly installed on the front surface of several rectangular partitions 704, and the front end of the adaptation spring 705 is fixedly connected to the L-shaped limiting block 703.

[0037] The liquid will enter the rectangular hollow tube 702 along the gaps between several rectangular partitions 704. The liquid will push the L-shaped limiting block 703 to move away from the hollow tube 607, and the adaptation spring 705 will undergo corresponding tensile deformation.

[0038] As Figure 8 shown, a rectangular installation groove 706 is formed on the front surface of the L-shaped limiting block 703. A rotating round rod 707 is rotatably installed inside the rectangular installation groove 706. A rubber block 708 is fixedly sleeved on the rotating round rod 707, and several rubber bumps 709 are fixedly installed on the front surface of the rubber block 708.

[0039] When the rubber block 708 is not in close contact with the inner ring of the bearing, the rubber bumps 709 will increase the friction between the rubber block 708 and the bearing. When the L-shaped limiting block 703 rotates, the corresponding rubber block 708 will cause the rotating round rod 707 to rotate at the contact with the inner ring of the bearing, resulting in a slight angular deviation of the rubber block 708. The angular deviation of the rubber block 708 will increase the friction between the rubber block 708 and the inner ring of the bearing, ensuring that the rubber block 708 can drive the bearing to rotate more effectively when rotating, and ensuring that the intelligent sensor 503 can stably conduct a comprehensive inspection on the outer ring of the bearing.

[0040] During use, first place the bearing to be detected on the roller 509 from top to bottom. When the bearing falls onto the roller 509 and the gripper is released, the bearing will evenly fall onto the roller 509. At this time, the roller 509 will descend due to the gravity of the bearing. The roller 509 will drive the limit block 3 to descend, the limit block 3 will drive the rectangular limit rod 506 to descend, the rectangular limit rod 506 will drive the special-shaped plate 501 to descend, and the special-shaped plate 501 will drive the triangular plate 504 to descend. During the descent of the triangular plate 504, it will contact the U-shaped round rod 505. The U-shaped round rod 505 will cause the triangular plate 504 to move away from the U-shaped round rod 505 under the action of the inclined plane of the triangular plate 504. At this time, the triangular plate 504 will drive the special-shaped plate 501 to move synchronously. The larger the size of the bearing, the greater its gravitational potential energy. Correspondingly, the triangular plate 504 will be farther away from the U-shaped round rod 505. When the special-shaped plate 501 moves, the corresponding adjustment spring 507 will undergo compressive deformation. When the triangular plate 504 stops moving, the corresponding special-shaped plate 501 will also stop moving. When the special-shaped plate 501 moves, it will drive the mounting plate 502 to move, and the mounting plate 502 will drive the intelligent sensor 503 to move synchronously. Since the bearings are all made of high-carbon chromium bearing steel, the intelligent sensor 503 will make corresponding adjustments according to the size and weight of the bearing to ensure an effective detection distance between the intelligent sensor 503 and the outer ring of the bearing, improving the applicable range and flexibility of the device and enabling effective detection of bearings of different sizes; During the descent of the limit block 3, it will drive the connecting rod 510 to descend, the connecting rod 510 will drive the circular plate 511 to descend, the circular plate 511 will drive the push rod 512 to descend, the push rod 512 will drive the transmission circular plate 603 to descend, and the transmission circular plate 603 will push the liquid in the transmission hydraulic tank 601 to descend. At this time, the liquid in the transmission hydraulic tank 601 will flow into the transmission strip box 604, the liquid will enter the U-shaped circular tube 605 from the transmission strip box 604, the liquid will enter the annular hollow box 608 from the U-shaped circular tube 605, and then the liquid will enter the hollow tube 607 from the through slot 609. Since the larger the size of the bearing, the greater its mass, and the greater the mass of the bearing, the greater the distance the transmission circular plate 603 will descend, and more liquid in the transmission hydraulic tank 601 will flow into the hollow tube 607. Due to the increase in hydraulic pressure in the hollow tube 607, the liquid will enter the rectangular hollow tube 702 along the gaps between several rectangular partitions 704, and the liquid will push the L-shaped limit block 703 to move away from the hollow tube 607. At this time, the adaptation spring 705 will undergo corresponding tensile deformation. The L-shaped limit block 703 will drive the rotating round rod 707 to move, and the rotating round rod 707 will drive the rubber block 708 to press against the inner ring of the bearing to support and fix the bearing, ensuring the bearing remains stable during detection and preventing detection errors caused by the bearing shaking during detection; After fixing the bearing, start the drive motor 606. The drive motor 606 drives the hollow tube 607 to rotate. The hollow tube 607 drives several connecting boxes 701 to rotate. The connecting box 701 drives the rectangular hollow tube 702 to rotate. The rectangular hollow tube 702 drives several L-shaped limit blocks 703 to rotate. The L-shaped limit block 703 drives the rotating round rod 707 to rotate. The rotating round rod 707 drives the rubber block 708 to rotate. The rubber block 708 will drive the bearing to rotate under the action of friction. Since the rotating rod 508 can rotate, the roller 509 will also rotate during the rotation of the bearing, which can effectively reduce the friction between the bearing and the roller 509 and make the bearing rotate more smoothly. If the rubber block 708 is not closely attached to the inner ring of the bearing, the rubber convex block 709 will increase the friction between the rubber block 708 and the bearing. When the L-shaped limit block 703 rotates, the corresponding rubber block 708 will cause the rotating round rod 707 to rotate at the contact with the inner ring of the bearing, which will cause a slight angular deviation of the rubber block 708. The angular deviation of the rubber block 708 will increase the friction between the rubber block 708 and the inner ring of the bearing, ensuring that the bearing can be driven more effectively when the rubber block 708 rotates and ensuring that the intelligent sensor 503 can stably perform a comprehensive detection on the outer ring of the bearing.
