[0042] like Figures 1 to 10As shown, an embodiment of the present invention provides a radian detection device for bearing processing, comprising a base 1, a control console 11 is fixedly connected to one side of the base 1, a rotating table 3 and a Y-axis lifting table 2 are fixedly connected to the top two sides of the base 1 respectively, an X-axis telescopic table 21 is transmission-connected to the Y-axis lifting table 2, a measuring rod 22 is transmission-connected to the X-axis telescopic table 21, a measuring sensor 23 is fixedly connected to one end of the measuring rod 22, a turntable 4 is rotatably connected to the top of the rotating table 3, a driving rotation is provided in the rotating table 3, which is used to drive the turntable 4 to rotate, thereby driving the bearing to be detected fixed on the turntable 4 to rotate in a circle, the Y-axis lifting table 2 is used to drive the X-axis telescopic table 21 to lift, the X-axis telescopic table 21 is used to drive the measuring rod 22 to telescope, the measuring sensor 23 is a length sensor, which is used to measure the radian of the bearing to be detected, wherein the Y-axis lifting table 2, the X-axis telescopic table 21, the measuring rod 22, the measuring sensor 23 and the rotating table 3 are all prior art; the outer ring limiting structure 5, the outer ring The limiting structure 5 is located at the bottom of the turntable 4 and is connected thereto. The outer ring limiting structure 5 is used for limiting and fixing the outer ring of the bearing to be tested; the inner ring limiting structure 6, the outer ring limiting structure 5 is located at the bottom of the turntable 4, and the turntable 4 is used for limiting and fixing the inner ring of the bearing to be tested; the blocking structure 7, the blocking structure 7 is located between the outer ring limiting structure 5 and the turntable 4 and is connected thereto. The blocking structure 7 is used for auxiliary limiting the outer ring limiting structure 5 to prevent the outer ring limiting structure 5 from shifting in position during the detection process. The inner and outer rings of the bearing to be tested are limited and fixed by the cooperation of the outer ring limiting structure 5 and the inner ring limiting structure 6. The staff can directly insert the bearing to be tested, which is convenient for placing and removing the bearing to be tested, shortening the time of the entire detection process and increasing work efficiency. The blocking structure 7 is then used for clamping and limiting, and the position of the outer ring limiting structure 5 is locked to avoid displacement of the outer ring limiting structure 5 and the inner ring limiting structure 6 during the detection process, which may lead to errors in the detection results.
[0043] When detecting the curvature of the bearing, the inner ring of the bearing to be detected is pressed against the inner ring limiting structure 6. At the same time, when pressing against the inner ring limiting structure 6, the outer ring of the bearing to be detected will contact the outer ring limiting structure 5, and the outer ring of the bearing will squeeze the outer ring limiting structure 5 until it is pressed to the bottom of the turntable 4. At this time, the inner ring limiting structure 6 will limit the inner ring of the bearing to be detected, and at the same time, the outer ring limiting structure 5 will also limit the outer ring of the bearing to be detected. Then, through the control console 11, the Y-axis lifting platform 2 and the X-axis telescopic platform 21 are controlled, so that the measuring sensor 23 on the measuring rod 22 contacts the outer ring of the bearing to be detected, and the rotating table 3 is controlled to drive the turntable 4 to rotate, thereby driving the bearing to be detected on the turntable 4 to rotate and measure.
[0044] like Figure 3 and Figure 6As shown, the bottom of the turntable 4 is provided with four outer ring limiting grooves 43 distributed at 90° to each other, the outer ring limiting grooves 43 are used to provide installation space for the outer ring limiting rods 44, both ends of each outer ring limiting groove 43 are fixedly connected with outer ring limiting rods 44, the outer ring limiting rods 44 are used to provide a sliding track for the outer ring limiting seat 52, and provide an installation position for the outer ring reset spring 51, the bottom of the turntable 4 is provided with an inner ring limiting groove 41 which is at an angle of 45° to the outer ring limiting groove 43, the inner ring limiting groove 41 is used to provide installation space for the inner ring limiting rods 42, the four ends of the inner ring limiting groove 41 are fixedly connected with the inner ring limiting rods 42, the inner ring limiting rods 42 are used to provide a sliding track for the inner ring limiting seat 66, and provide an installation position for the inner ring reset spring 61, wherein the outer ring limiting rods 44 and the inner ring limiting rods 42 have the same diameter, and the inner ring limiting seat 66 and the outer ring limiting seat 52 have the same structure and specification.
[0045] like Figures 2 to 5 As shown, the outer ring limiting structure 5 includes an outer ring limiting seat 52 sleeved on the outer surface wall of the outer ring limiting rod 44, and an open adapting groove matched with the outer ring limiting rod 44 is provided on the outer ring limiting seat 52, and its opening is smaller than the diameter of the outer ring limiting rod 44, so that the outer ring limiting seat 52 will not fall off the outer ring limiting rod 44, and the outer surface wall of the outer ring limiting rod 44 is sleeved with an outer ring return spring 51, and the two ends of the outer ring return spring 51 are respectively fixedly connected to the outer ring limiting seat 52 and one end of the outer ring limiting groove 43, and the outer ring return spring 51 is used to provide extrusion force for the outer ring limiting piece 53, so that the outer ring limiting piece 53 squeezes and limits the outer ring of the bearing to be detected under the elastic force of the outer ring return spring 51, and the outer ring limiting piece 53 is fixedly connected to the top of the outer ring limiting seat 52, The outer ring limit piece 53 is an elastic structure, and the outer ring limit piece 53 is connected in sequence by an introduction section 531, a first deformation section 532, a first fitting section 533, a second fitting section 534, a second deformation section 535 and a fixed section 536. The bottom of the fixed section 536 is fixedly connected to the top of the outer ring limit seat 52, and the bottom of the fixed section 536 is fitted with the bottom surface of the turntable 4. The second deformation section 535, the first fitting section 533 and the first deformation section 532 are concave structures, and their thickness gradually changes from thin to thick from the middle to the two ends. The introduction section 531 is an outward-turned structure, and a rubber strip 54 is fixedly connected to the surface of one side of the first fitting section 533. The rubber strip 54 is used to increase the friction between the bearing to be detected to prevent the bearing to be detected from rotating during the detection process.
[0046] When the staff presses the bearing to be tested, the outer ring of the bearing to be tested will first contact with the outward-turned introduction section 531. As the staff continues to press, the bearing to be tested will squeeze the introduction section 531. The squeezing force will cause the first deformation section 532 to deform, thereby driving the introduction section 531 to flip outward. After passing through the introduction section 531, the bearing to be tested will contact the first fitting section 533. As the staff continues to press, the bearing to be tested will squeeze the first fitting section 533, driving the second deformation section 535 to deform, until the entire bearing to be tested is pressed to fit with the bottom of the turntable 4. At this time, the first fitting section 533 and the second fitting section 534 are in a vertical state, squeezing and limiting the outer ring surface wall of the bearing to be tested, and four outer ring limiting structures 5 distributed at 90° to each other fix the bearing to be tested.
[0047] like Figure 6 and Figure 7 As shown, the inner ring limiting structure 6 includes an inner ring limiting seat 66 sleeved on the outer wall of the inner ring limiting rod 42, the outer wall of the inner ring limiting rod 42 is sleeved with an inner ring reset spring 61, the two ends of the inner ring reset spring 61 are respectively fixedly connected to the inner ring limiting seat 66 and one end of the inner ring limiting rod 42, the top of the inner ring limiting seat 66 is fixedly connected with a mounting seat 62, one side of the mounting seat 62 is fixedly connected with a guide bar 63, the guide bar 63 is used to guide the inner ring of the bearing to be detected, and the two sides of the guide bar 63 are fixedly connected with adapter pieces 64, the adapter piece 64 is an arc-shaped elastic structure, when the inner ring of the bearing to be detected is limited and fixed by the limiting segment 633, the adapter piece 64 fits with the inner ring of the bearing to be damped under the action of its own elastic force, increases friction and prevents it from rotating, the guide bar 63 is mainly composed of a guide segment 631, a connecting segment 632 and a limiting segment 633. Segment 631 is an arc-shaped structure with a convex top and concave middle and lower ends. The limiting segment 633 is fixedly connected to one side of the mounting seat 62 and is perpendicular to the bottom surface of the turntable 4. The two ends of the connecting segment 632 are fixedly connected to the guide segment 631 and the limiting segment 633 respectively. The connecting segment 632 is a quarter-circular arc structure. The adapter piece 64 is a convex fan-shaped structure. When the bearing to be tested moves on the guide segment 631, it will contact the top of the adapter piece 64 with the fan-shaped structure. The arc-shaped edge of the inner ring of the bearing will squeeze the adapter piece 64 to deform inward until the entire adapter piece 64 enters the inner ring of the bearing to be tested. Therefore, the adapter piece 64 with the fan-shaped structure can adapt to bearings to be tested of various sizes. A reinforcing rib 65 is fixedly connected between the inner side of the guide strip 63 and the top of the mounting seat 62. The reinforcing rib 65 is used to strengthen the guide strip 63 to prevent it from being deformed under the squeezing of the bearing to be tested.
[0048] When the staff presses the bearing to be tested, the inner ring of the bearing to be tested will contact the guide section 631 first. As the staff continues to press, the inner ring of the bearing to be tested will squeeze the guide section 631. While squeezing, the four guide strips 63 will move toward the center position of the turntable 4 as the bearing to be tested descends, until the inner ring of the bearing to be tested passes through the connecting section 632 along the surface of the guide section 631 and fits the surface of the limiting section 633. The four limiting sections 633 at 90° to each other will limit the inner ring of the bearing to be tested in four directions.
[0049] like Figures 8 to 10 As shown, the blocking structure 7 includes a moving inserting strip 71 fixedly connected to one side of the second fitting section 534. The moving inserting strip 71 is an arc-shaped structure arranged at a 45° angle with the bottom surface of the rotating disk 4. The moving inserting strip 71 is arranged at a 45° angle, so that when the outer ring limiting structure 5 moves, it will drive the moving inserting strip 71 to enter and be pulled out at an angle on the insertion port 734, forming an angle of nearly 45° with the clamping section 733. A fixed strip 73 is fixedly connected to the corresponding position of the bottom edge of the rotating disk 4 and the moving inserting strip 71. The fixed strip 73 is used to move The inserting strip 71 is engaged and limited, and a through insertion port 734 is provided on the fixed strip 73. The cross-sectional size of the insertion port 734 is larger than the cross-sectional size of the movable inserting strip 71 when passing through, so that the movable inserting strip 71 can slide easily on the insertion port 734. One end of the movable inserting strip 71 passes through the insertion port 734 and extends to the other side of the fixed strip 73. The movable inserting strip 71 and the fixed strip 73 cross to form an X-shaped structure. A baffle plate 735 is fixedly connected to the top of the insertion port 734. The setting of the baffle plate 735 prevents the insertion port 734 from being blocked. The upper end is engaged with the bayonet 72, resulting in the situation that the insertion interface 734 is stuck to the movable insertion strip 71. The fixed strip 73 is mainly connected by a stabilizing section 731, a third deformation section 732 and a clamping section 733. The bottom end of the stabilizing section 731 is fixedly connected to the bottom of the turntable 4. The stabilizing section 731 is made of a rigid material and is not easily deformed, so as to avoid the problem that the movable insertion strip 71 drives the stabilizing section 731 to deform, resulting in a poor limiting effect. The two ends of the third deformation section 732 are respectively fixedly connected with the stabilizing section 731 and the clamping section 733. The connecting section 733 is used to adapt to the bayonet 72. The bayonet 72 and the bayonet 72 are mutually engaged, so as to limit the movable insertion strip 71 on the fixed strip 73. The third deformation section 732 is an outward-turned structure. A connecting rod 74 is fixedly connected to one side of the third deformation section 732. The other end of the connecting rod 74 is fixedly connected to one side of the introduction section 531. The thickness of the third deformation section 732 gradually changes from thick to thin from the stabilizing section 731 to the connecting section 733. A plurality of evenly distributed bayonet 72 are provided on one side surface of the movable insertion strip 71.
[0050] When the bearing to be tested is squeezed by the introduction section 531, it is turned outward, and the turned introduction section 531 squeezes the connecting rod 74, so that the third deformation section 732 is not easy to deform under the squeezing force of the connecting rod 74. At the same time, the angle between the clamping section 733 and the movable insertion strip 71 is about 45 degrees. With the squeezing of the bearing to be tested, the outer ring limiting structure 5 will be driven to move in the squeezing direction. When moving, the second fitting section 534 will drive the movable insertion strip 71 to move in the direction of the fixed strip 73, so the movable insertion strip 71 will move along the insertion port 734. Since the angle between the clamping section 733 and the movable insertion strip 71 is small, the bayonet 72 on the movable insertion strip 71 can be moved from the lower side of the clamping section 733. The outer ring limit structure 5 is fixed in the outer ring return spring 51, and the outer ring return spring 51 is used to return the outer ring limit structure 5 to the original position.
[0051] The present application also provides a detection method of a radian detection device for bearing processing, comprising the following steps:
[0052] S1. When testing the curvature of the bearing, the inner ring of the bearing to be tested is pressed against the inner ring limiting structure 6 until it is pressed to the bottom of the turntable 4, and the inner ring limiting structure 6 will limit the inner ring of the bearing to be tested;
[0053] S2, when pressing against the inner ring limiting structure 6, the outer ring of the bearing to be tested will contact the outer ring limiting structure 5, and the outer ring of the bearing will squeeze the outer ring limiting structure 5. When the bearing is pressed to the bottom of the turntable 4, the outer ring limiting structure 5 also limits the outer ring of the bearing to be tested;
[0054] S3, at the same time, the outer ring limiting structure 5 will drive the movable inserting strip 71 to the upper limit of the fixed strip 73, thereby limiting the position of the outer ring limiting structure 5;
[0055] S4. After the bearing to be tested is fixed, the control console 11 is used to control the Y-axis lifting platform 2 and the X-axis telescopic platform 21, so that the measuring sensor 23 on the measuring rod 22 contacts the outer ring of the bearing to be tested, and the rotating table 3 is controlled to drive the turntable 4 to rotate, thereby driving the bearing to be tested on the turntable 4 to rotate and measure.
[0056] The working principle of the technical solution provided by the present invention is as follows: when detecting the curvature of the bearing, the inner ring of the bearing to be detected is pressed against the inner ring limiting structure 6. When the staff presses the bearing to be detected, the inner ring of the bearing to be detected will preferentially contact the guide section 631. As the staff continues to press, the inner ring of the bearing to be detected will squeeze the guide section 631. While squeezing, the four guide strips 63 will move toward the center position of the turntable 4 as the bearing to be detected descends, until the inner ring of the bearing to be detected passes through the connecting section 632 along the surface of the guide section 631 and fits the surface of the limiting section 633. The four limiting sections 633 at 90° to each other will limit the inner ring of the bearing to be detected in four directions.
[0057] At the same time, when pressing against the inner ring limiting structure 6, the outer ring of the bearing to be tested will contact the outer ring limiting structure 5, the outer ring of the bearing will squeeze the outer ring limiting structure 5, and the outer ring of the bearing to be tested will preferentially contact the outward-turned introduction section 531. As the staff continues to press, the bearing to be tested will squeeze the introduction section 531, and the squeezing force will cause the first deformation section 532 to deform, thereby driving the introduction section 531 to flip outward. After passing through the introduction section 531, the bearing to be tested will contact the first fitting section 533. As the staff continues to press, the bearing to be tested will squeeze the first fitting section 533, driving the second deformation section 535 to deform, until the entire bearing to be tested is pressed to fit with the bottom of the turntable 4. At this time, the first fitting section 533 and the second fitting section 534 are in a vertical state, squeezing and limiting the outer ring surface wall of the bearing to be tested, and the four outer ring limiting structures 5 distributed at 90° to each other fix the bearing to be tested.
[0058] When the bearing to be tested is squeezed by the introduction section 531, it is turned outward. The turned introduction section 531 will squeeze the connecting rod 74, making the third deformation section 732 not easy to deform under the squeezing force of the connecting rod 74. At the same time, the angle between the clamping section 733 and the movable insertion strip 71 is about 45°. As the bearing to be tested is squeezed, the outer ring limiting structure 5 will be driven to move in the squeezing direction. During the movement, the second fitting section 534 will drive the movable insertion strip 71 to move in the direction of the fixed strip 73, so the movable insertion strip 71 will move along the insertion interface 734. Since the angle between the clamping section 733 and the movable insertion strip 71 is small, the bayonet 72 on the movable insertion strip 71 can move from the bottom of the clamping section 733 to the outside until the entire bearing to be tested is placed. The movable insertion strip 71 is clamped into the bayonet 72 to prevent the movable insertion strip 71 from moving back, thereby fixing the entire outer ring limiting structure 5.
[0059] After the bearing to be tested is fixed, the control console 11 is used to control the Y-axis lifting platform 2 and the X-axis telescopic platform 21, so that the measuring sensor 23 on the measuring rod 22 contacts the outer ring of the bearing to be tested, and the rotating table 3 is controlled to drive the turntable 4 to rotate, thereby driving the bearing to be tested on the turntable 4 to rotate and measure. After the measurement is completed, the bearing can be removed by bending it upwards, and then the above operation is repeated to test the next bearing to be tested.
