Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing ring detection machine. Background Art
[0002] Bearings are an important part of mechanical motion structures and can be divided into two categories: sliding bearings and rolling bearings. The commonly known bearings usually refer to rolling bearings. Rolling bearings have many subordinate branches, such as ball bearings, roller bearings, self-aligning bearings, etc. Their function is to support rotating bodies and reduce the friction coefficient during the movement of rotating bodies. Bearing components are relatively simple, mainly consisting of an inner ring, an outer ring, rollers (rollers), a sealing cover, and a retaining frame. The inner and outer rings of the bearings require a lot of inspections after production, such as size inspection, end face inspection, deep groove inspection, etc.
[0003] The existing bearing ring size inspection machine mainly measures and inspects the inner diameter and outer diameter of the bearing ring to determine whether the bearing size meets the standard. If it meets the standard, it can be sent to the next step for other inspections or assembly. If the bearing size does not meet the standard, it needs to be re-cut to remove the excess, or discarded and made into raw materials and reprocessed into bearing rings;
[0004] When inspecting the size of the bearing ring, since there are two parameters, the inner diameter and the outer diameter, and the bearing ring is a closed circular ring structure, the staff needs to disassemble and assemble the bearing ring many times. For example, the staff first puts the bearing ring into the detection machine to detect the outer diameter of the bearing, and then the staff takes out the bearing ring and puts the bearing ring into another detection machine, or adjusts the position of the measuring tool in the detection machine to an inner position, and then the staff puts the bearing ring back to detect the inner diameter of the bearing ring. The operation is relatively cumbersome. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a bearing ring detection machine to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing ring detection machine, comprising a workbench, wherein a bidirectional screw and a guide rod are respectively connected inside the workbench, and a slide is connected between the bidirectional screw and the guide rod, a measuring frame is connected to the top of the slide, and a through-beam photoelectric rangefinder is installed inside the measuring frame; a limit hole is provided on the outer surface of the measuring frame; a damper and a tension spring are respectively arranged at the lower part of the slide, and a connecting plate is fixed on the top of the damper and the tension spring, and a pull rope is connected between the measuring frame and the connecting plate; electromagnets are installed on the outer surface and back of the slide, a limit rod is connected to the inner wall of the slide, and a spring is connected inside the limit rod.
[0007] By adopting the above technical solution, the slide is displaced toward the bearing ring. When the measuring frame is against the outer ring of the bearing ring, the distance between the four measuring frames is measured by the opposing photoelectric distance meter, thereby obtaining the outer diameter of the bearing ring; then the slide continues to displace toward the center of the bearing ring. At this time, the measuring frame is forced to rotate ninety degrees so that the measuring frame can pass through the bearing ring. The measuring frame rotates to move the connecting plate up through the pull rope, thereby stretching the damper and the tension spring. After the measuring frame passes through the bearing ring, the tension spring pulls the connecting plate down so that the pull rope pulls the measuring frame to reverse and reset. At the same time, the damper is used to reduce inertia to prevent the measuring frame from swinging left and right. Then the measuring frame is displaced toward the outer circle of the bearing ring so that the measuring frame is against the inner ring of the bearing ring. At this time, the distance between the four measuring frames is still measured by the opposing photoelectric distance meter, and the diameter of the measuring frame is added to obtain the inner diameter of the bearing ring.
[0008] Furthermore, the slide is threadedly connected to the bidirectional lead screw, and the slide is slidably connected to the guide rod and the workbench.
[0009] By adopting the above technical solution, after the two motors are started, the output ends respectively drive the two bidirectional lead screws to rotate, and after the bidirectional lead screws rotate, they cooperate with the guide rods to move the slide toward the bearing direction.
[0010] Furthermore, the measuring frame is rotatably connected to the slide, and the connecting plate is slidably connected to the slide.
[0011] By adopting the above technical solution, the measuring frame is forced to rotate downward by ninety degrees to facilitate the measuring frame to pass through the bearing ring. While the measuring frame rotates, the connecting plate is moved up by the pull rope, so that the damper and the tension spring are stretched. After the measuring frame passes through the bearing ring, the tension spring pulls the connecting plate downward, so that the pull rope pulls the measuring frame to reverse and reset.
[0012] Furthermore, the pull rope is a steel wire rope.
[0013] By adopting the above technical solution, the pull rope is made of steel wire rope and has good structural strength, so it can be used for a long time, thereby extending the service life of the structure and reducing the difficulty of maintenance.
[0014] Furthermore, the limiting rod is made of carbon steel.
[0015] By adopting the above technical solution, the limit rod made of carbon steel has a high structural strength. Therefore, using the limit rod to limit the measuring frame can prevent the measuring frame from rotating during the detection process, and the carbon steel with low chromium content can be attracted by the magnet, so that the electromagnet is started to generate magnetic attraction to displace the limit rod and move it out of the limit hole to end the limit.
[0016] Furthermore, the limiting rod is detachably connected to the limiting hole, and the limiting rod is slidably connected to the slide.
[0017] By adopting the above technical solution, the electromagnet is started to generate magnetic attraction to displace the limit rod and move it out of the limit hole. At the same time, the limit rod compresses the spring, so that the measuring frame can rotate. After the electromagnet is turned off, the spring drives the limit rod into the limit hole to prevent the measuring frame from rotating during the detection process.
[0018] Furthermore, there are four slides, measuring frames, through-beam photoelectric rangefinders, dampers, connecting plates, pull ropes and limit holes, and the four slides, measuring frames, through-beam photoelectric rangefinders, dampers, connecting plates, pull ropes and limit holes are distributed in a circular array.
[0019] By adopting the above technical solution and increasing the number of structures such as slides and measuring frames, the bearing ring can be clamped and limited to avoid the bearing ring being offset or running away during the measurement process, which affects the measurement.
[0020] Furthermore, eight of the tension springs, electromagnets, springs and limit rods are provided, two in a group, and a total of four groups, and the four groups of tension springs, electromagnets, springs and limit rods are distributed in a ring array.
[0021] By adopting the above technical solution and increasing the number of structures such as tension springs and electromagnets, it is possible to match four slides, a measuring frame, a through-beam photoelectric rangefinder, a damper, a connecting plate, a pull rope and a limit hole.
[0022] Furthermore, two motors are installed on one side and the outer surface of the workbench respectively, two bidirectional screw rods and two guide rods are provided, and the output ends of the two motors are connected to the two bidirectional screw rods respectively.
[0023] By adopting the above technical solution, the staff places the bearing ring in the middle area of the workbench, and then turns on the two motors. After the two motors are started, the output ends respectively drive the two bidirectional screws to rotate.
[0024] Furthermore, a protective sleeve is sleeved on the outside of the measuring frame, and the protective sleeve is made of rubber material.
[0025] By adopting the above technical solution, when the measuring frame abuts against the outer ring of the bearing ring, the protective sleeve plays a buffering role, thereby reducing the phenomenon of the measuring frame crushing the bearing ring.
[0026] In summary, the utility model mainly has the following beneficial effects:
[0027] 1. The utility model is provided with a slide, a measuring frame, a beam-type photoelectric distance meter, a damper, a pull rope and a tension spring. The slide moves toward the bearing ring. When the measuring frame abuts against the outer ring of the bearing ring, the distance between the four measuring frames is measured by the beam-type photoelectric distance meter, so as to obtain the outer diameter of the bearing ring. Then the slide continues to move toward the center of the bearing ring. At this time, the measuring frame is forced to rotate ninety degrees, so that the measuring frame passes through the bearing ring. The measuring frame rotates and the connecting plate moves up through the pull rope, so that the damper and the tension spring are stretched. After the measuring frame passes through the bearing ring, the tension spring pulls the connecting plate down to make the pull rope pull the measuring frame to reverse and reset. At the same time, the damper is used to reduce inertia to prevent the measuring frame from swinging left and right. Then the measuring frame moves toward the outer circle of the bearing ring, so that the measuring frame abuts against the inner ring of the bearing ring. At this time, the distance between the four measuring frames is still measured by the beam-type photoelectric distance meter, and the diameter of the measuring frame is added to obtain the inner diameter of the bearing ring. There is no need to disassemble and replace, and the inner diameter and outer diameter of the bearing ring can be directly measured at one time.
[0028] 2. The utility model arranges an electromagnet, a limit hole, a spring and a limit rod. The limit rod is caused to enter the limit hole by the spring, thereby preventing the measuring frame from rotating during the measurement process and affecting the measurement accuracy. When the measuring frame needs to be moved to the inner ring of the bearing ring or the outer ring of the bearing ring for detection, the electromagnet is started to generate a magnetic force to displace the limit rod and move it out of the limit hole. At the same time, the limit rod compresses the spring, so that the measuring frame can rotate ninety degrees and pass through the bearing ring, making measurement convenient.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0036] The following describes an embodiment of the utility model based on its overall structure.
[0037] Embodiment 1:
[0038] A bearing ring detection machine, such as Figure 1-Figure 5 As shown, it includes a workbench 1, wherein a bidirectional screw rod 3 and a guide rod 4 are respectively connected inside the workbench 1, a slide 6 is connected between the bidirectional screw rod 3 and the guide rod 4, the slide 6 is threadedly connected to the bidirectional screw rod 3, the slide 6 is slidably connected to the guide rod 4 and the workbench 1, a measuring frame 7 is connected to the top of the slide 6, the measuring frame 7 is rotatably connected to the slide 6, a counter-beam photoelectric distance meter 8 is installed inside the measuring frame 7, after the bidirectional screw rod 3 rotates, it cooperates with the guide rod 4 to make the slide 6 move toward the bearing direction, when the measuring frame 7 abuts against the outer ring of the bearing ring, the distance between the four measuring frames 7 is measured by the counter-beam photoelectric distance meter 8, so as to obtain the outer diameter of the bearing ring;
[0039] A damper 9 and a tension spring 12 are respectively arranged at the lower part of the slide 6. A connecting plate 10 is fixed on the top of the damper 9 and the tension spring 12. The connecting plate 10 is slidably connected to the slide 6. A pull rope 11 is connected between the measuring frame 7 and the connecting plate 10. The pull rope 11 is a steel wire rope. The measuring frame 7 is against the bearing, so that the measuring frame 7 is forced to rotate downward by ninety degrees, so that the measuring frame 7 passes through the bearing ring. The measuring frame 7 rotates and the connecting plate 10 is moved up by the pull rope 11, so that the damper 9 and the tension spring 12 are stretched. After the measuring frame 7 passes through the bearing ring, the tension spring 12 pulls the connecting plate 10 downward so that the pull rope 11 pulls the measuring frame 7 to reverse and reset. At the same time, the damper 9 is used to reduce inertia to prevent the measuring frame 7 from swinging left and right.
[0040] A limit hole 14 is provided on the outer surface of the measuring frame 7, and electromagnets 13 are installed on the outer surface and the back of the slide 6. A limit rod 16 is connected to the inner wall of the slide 6. The limit rod 16 is made of carbon steel. The limit rod 16 is detachably connected to the limit hole 14, and the limit rod 16 is slidably connected to the slide 6. A spring 15 is connected inside the limit rod 16. When the measuring frame 7 is against the outer ring of the bearing ring, the limit rod 16 cooperates with the limit hole 14 to prevent the measuring frame 7 from rotating during the measurement process and affecting the measurement accuracy.
[0041] See also Figure 1-Figure 4In the above embodiment, the slide 6, the measuring frame 7, the through-beam photoelectric rangefinder 8, the damper 9, the connecting plate 10, the pull rope 11 and the limit hole 14 are each provided with four, and the four slides 6, the measuring frame 7, the through-beam photoelectric rangefinder 8, the damper 9, the connecting plate 10, the pull rope 11 and the limit hole 14 are all distributed in a circular array, and the tension spring 12, the electromagnet 13, the spring 15 and the limit rod 16 are each provided with eight, two in a group, and a total of four groups, and the four groups of tension springs 12, electromagnets 13, springs 15 and limit rods 16 are all distributed in a circular array. By increasing the number, it is convenient to clamp the bearing ring for measurement, and avoid the bearing ring from deviating or running and affecting the measurement accuracy.
[0042] See also Figure 1 and Figure 2 In the above embodiment, two motors 2 are respectively installed on one side and the outer surface of the workbench 1, and two bidirectional screw rods 3 and guide rods 4 are each provided. The output ends of the two motors 2 are respectively connected to the two bidirectional screw rods 3. The staff turns on the two motors 2. After the two motors 2 are started, the output ends respectively drive the two bidirectional screw rods 3 to rotate. After the bidirectional screw rods 3 rotate, they cooperate with the guide rods 4 to move the slide 6.
[0043] Embodiment 2:
[0044] Based on the above embodiment 1, it is not possible to avoid the bearing ring being crushed due to excessive force applied by the measuring frame 7, and the following settings are now adopted.
[0045] See also Figure 1 In the above embodiment, the outer portion of the measuring frame 7 is sleeved with a protective sleeve 5, which is made of rubber material. When the measuring frame 7 abuts against the outer ring of the bearing ring, the protective sleeve 5 acts as a buffer to reduce the phenomenon of the measuring frame 7 crushing the bearing ring.
[0046] The implementation principle of the utility model is as follows: first, the staff places the bearing ring in the middle area of the workbench 1, and then the staff turns on the two motors 2. After the two motors 2 are started, the output ends drive the two bidirectional screws 3 to rotate respectively. After the bidirectional screws 3 rotate, they cooperate with the guide rods 4 to move the slide 6 toward the bearing direction;
[0047] When the measuring frame 7 abuts against the outer ring of the bearing ring, the protective sleeve 5 plays a buffering role to reduce the phenomenon of the measuring frame 7 crushing the bearing ring, and the limiting rod 16 cooperates with the limiting hole 14 to prevent the measuring frame 7 from rotating during the measurement process to affect the measurement accuracy. At this time, the staff turns off the motor 2 and measures the distance between the four measuring frames 7 through the opposing photoelectric rangefinder 8 to obtain the outer diameter of the bearing ring;
[0048] When the staff needs to inspect the inner diameter of the bearing ring, the staff turns on the motor 2 and the electromagnet 13. The electromagnet 13 starts to generate magnetic attraction to displace the limit rod 16 and move it out of the limit hole 14. At the same time, the limit rod 16 compresses the spring 15, so that the measuring frame 7 can rotate. Then the motor 2 drives the slide 6 to move toward the center of the bearing ring through the two-way screw 3 and the guide rod 4. At this time, the measuring frame 7 is against the bearing, so that the measuring frame 7 is forced to rotate downward by 90 degrees, so that the measuring frame 7 can pass through the bearing ring. The measuring frame 7 rotates and the connecting plate 10 is moved upward by the pull rope 11, so that the damper 9 and the tension spring 12 are stretched. After the measuring frame 7 passes through the bearing ring, the tension spring 12 pulls the connecting plate 10 downward so that the pull rope 11 pulls the measuring frame 7 to reverse and reset. At the same time, the damper 9 is used to reduce inertia to prevent the measuring frame 7 from swinging left and right. At the same time, the staff turns off the electromagnet 13 and the motor 2. After the electromagnet 13 is turned off, the spring 15 drives the limit rod 16 to enter the limit hole 14 to prevent the measuring frame 7 from rotating during the detection process.
[0049] The staff turns on the motor 2 so that the output end of the motor 2 drives the bidirectional screw 3 to reverse. At this time, the measuring frame 7 moves toward the outer circle of the bearing ring, so that the measuring frame 7 and the inner ring of the bearing ring are against each other. After the measuring frame 7 and the inner ring of the bearing ring are against each other, the motor 2 is turned off, and the distance between the four measuring frames 7 is measured by the opposing photoelectric distance meter 8, and then the diameter of the measuring frame 7 is added to obtain the inner diameter of the bearing ring;
[0050] For example, the through-beam photoelectric rangefinder 8 measures that the inner diameter of the bearing ring is five centimeters. Assuming that the diameter of the measuring frame 7 is three centimeters, the inner diameter of the bearing ring should be eight centimeters.
[0051] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
