Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a ferrule positioning and adjusting device. Background Art

[0002] When bearings are produced or used, the ring size needs to be tested. The test items include the inner diameter and outer diameter of the ring. The existing detection of the inner and outer diameters of the ring is generally carried out by three ring-shaped claws. When the outer diameter is detected, the ring is clamped by the synchronous movement of the three claws. The outer diameter of the ring is obtained by detecting the displacement of the claws. When the inner diameter is detected, the ring is supported and tensioned by the outward expansion of the three claws to obtain the inner diameter of the ring. Due to the thickness of the claws themselves, the existing detection device can only detect one of the inner diameter or outer diameter of the ring, which is not universal and inconvenient to use. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a ring positioning and adjustment device. Through the setting of the positioning wheel, the driving disk rotates to drive the curved rod to move inward and outward. When the curved rod moves outward, the driving groove drives the curved rod to rotate half a circle in the opposite direction, so that the positioning wheel is deflected to a position where the axis of the bottom end of the curved rod is close to the center of the fixed platform. When the curved rod moves inward, the curved rod is driven to rotate half a circle in the forward direction, so that the positioning wheel is deflected to a position where the axis of the bottom end of the curved rod is away from the center of the fixed platform. When measuring the inner diameter and outer diameter of the ring, the contact points between the positioning wheel and the ring are both located on the axis of the bottom end of the curved rod, thereby realizing the measurement of the inner and outer diameters of the ring, which is convenient for use.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] Ferrule positioning adjustment device, including

[0006] Fixed plate, used to install and fix other components;

[0007] The fixing platform is located above the top surface of the fixing plate, and the annular outer wall of the fixing platform is provided with three chute 1s at equal angles in a circular shape, and the annular outer wall of the fixing platform is provided with chute 2s at positions corresponding to the three chute 1s;

[0008] Three positioning mechanisms are located on the outside of the fixed platform and fixedly connected to the fixed plate. The three positioning mechanisms correspond one to one with the three slide grooves. The positioning mechanism includes a fixed seat, the bottom end of the fixed seat is fixedly connected to the fixed plate, the top end of the fixed seat is rotatably connected to a sleeve, the inner wall of the sleeve is slidably sleeved with a sliding rod, one end of the sliding rod is slidably sleeved with an inner wall of the slide groove at the corresponding position, one end of the sliding rod is rotatably sleeved with a curved rod, and the top end of the curved rod is fixedly connected to a positioning wheel;

[0009] A driving plate is located at the bottom end of the fixed platform. The top surface of the driving plate is provided with three arcuate slots at equal angles. The three arcuate slots correspond to three curved rods one by one. The bottom ends of the curved rods are slidably connected to the inner walls of the arcuate slots.

[0010] A driving mechanism, the driving mechanism being located at the bottom end of the driving disk and being used to drive the driving disk to rotate, the driving mechanism being fixedly connected to the fixing plate;

[0011] The displacement detector is located at the top of the fixed plate. The displacement detector is fixedly installed at the top position of the fixed plate. The displacement probe of the displacement detector is fixedly connected to the other end of an adjacent sliding rod. The driving mechanism drives the driving disk to rotate forward. When the driving disk rotates forward, the arc-shaped through groove squeezes the bottom end of the curved rod to move outward, and the curved rod drives the sliding rod to move outward, so that the three curved rods move synchronously, and the ring is placed at the center position of the top surface of the fixed table. The driving mechanism makes the three curved rods move closer to the middle, and the three positioning wheels clamp and position the ring so that the contact point between the positioning wheel and the outer wall of the ring is on the axial center line of the bottom end of the curved rod. The displacement distance of a sliding rod at this time is obtained by the displacement detector, thereby obtaining the outer diameter of the ring.

[0012] Furthermore, the curved rod includes a curved portion located between the bottom end and the top end of the curved rod, and an avoidance groove is provided on the top surface of the fixed platform at a position of the slide groove, and the width of the avoidance groove is not less than the rotation diameter of the curved portion to avoid interference between the curved portion and the fixed platform when rotating.

[0013] Furthermore, a slider is fixedly connected to the outer side wall of one end of the sliding rod, the slider is rotatably sleeved with the curved rod, the top end of the slider is fixedly connected to a limit plate, and the bent portion is located above the slider to limit the rotation of the curved rod.

[0014] Furthermore, the distance between the bottom axis and the top axis of the crankshaft is equal to the radius of the positioning wheel, so that the positioning wheel deflects around the bottom axis of the crankshaft, and at the same time facilitates the contact point between the positioning wheel and the ring to be located on the axis of the bottom end of the crankshaft.

[0015] The invention also provides a plurality of sliding sleeves on the outer wall of the driving plate, and the sliding sleeve is connected to the inner wall of the driving plate, and the sliding sleeve is connected to the inner wall of the driving plate. The depths of the two sides of the driving groove are different, so that the rubber wheel only contacts the inner wall of one side of the driving groove. When the driving plate rotates forward, the sliding sleeve is squeezed by the arc groove to move the arc rod outward, and the arc rod drives the sliding rod outward. When the bottom end of the arc rod moves along the arc groove, the friction between the inner wall of the driving groove and the rubber wheel drives the arc rod to rotate half a circle in the opposite direction, thereby causing the positioning wheel to deflect to a position on the side of the axis of the bottom end of the arc rod close to the center of the fixed platform.

[0016] The top end of the fixing plate is fixedly mounted on the fixing plate, and the fixing plate is fixedly mounted on the fixing plate, wherein the fixing plate is fixedly mounted on the fixing plate, and the fixing plate is fixedly mounted on the fixing plate. The cam is fixedly connected to the bottom surface of the driving disk, and a spring 1 is fixedly connected between the fixed block 1 and the fixed block 2. The spring 1 and the spring 2 are both slidably connected to the arc-shaped slide groove. A pull rope is fixedly connected to an outer side wall of the fixed block 2, and one end of the pull rope extends through the threading hole to the outside of the fixed disk. The other end of the pull rope is pulled, and the pull rope pulls the fixed block 2 toward one end of the arc-shaped slide groove to deflect and slide, so that the spring 2 is compressed. The movement of the fixed block 2 causes the spring 1 to recover from the compressed state first and then be stretched. The fixed block 2 pulls the fixed block 1 through the spring 1, thereby driving the driving disk to rotate forward. Through the setting of the spring 1 and the spring 2, the driving disk can still pull the pull rope after stopping, so as to facilitate the extrusion contact between the positioning wheel and the ring.

[0017] Furthermore, the top surface of the fixed plate is located on one side of the fixed disk and is rotatably connected to a winding wheel, the top surface of the winding wheel is fixed with a handle, and one end of the pull rope is wrapped and fixed with the winding wheel to facilitate pulling the pull rope.

[0018] Furthermore, two legs are fixedly connected to the top of the bottom surface of the fixing plate, so that the fixing plate can be placed at an angle for easy observation and operation.

[0019] Beneficial effects of the present invention:

[0020] 1. Through the setting of the positioning wheel, the driving disc rotates to drive the crankshaft to move inward and outward. When the crankshaft moves outward, the driving groove drives the crankshaft to rotate half a circle in the opposite direction, so that the positioning wheel deflects to the position where the axis of the bottom end of the crankshaft is close to the center of the fixed platform. When the crankshaft moves inward, the crankshaft is driven to rotate half a circle in the forward direction, so that the positioning wheel deflects to the position where the axis of the bottom end of the crankshaft is away from the center of the fixed platform. When measuring the inner and outer diameters of the ferrule, the contact points between the positioning wheel and the ferrule are both on the axis of the bottom end of the crankshaft, thereby realizing the measurement of the inner and outer diameters of the ferrule, which is convenient for use.

[0021] 2. Through the setting of the driving mechanism, the winding wheel is rotated and the other end of the pull rope is pulled. The pull rope pulls the fixed block 2 to slide toward one end of the arc-shaped slide groove, so that the spring 2 is compressed. The movement of the fixed block 2 causes the spring 1 to recover from the compressed state and then be stretched. The fixed block 2 pulls the fixed block 1 through the spring 1, thereby driving the driving disk to rotate forward. Through the setting of the spring 1 and the spring 2, the driving disk can still pull the pull rope after stopping, which facilitates the extrusion contact between the positioning wheel and the ring, and facilitates the curved rod to drive the positioning wheel to clamp or tension the ring.

The inner wall of the sleeve 311 is slidably sleeved with a slide rod 320. One end of the slide rod 320 is slidably sleeved with the inner wall of the slide groove 210 at the corresponding position.

At the same time, the arc-shaped through groove 410 squeezes the bottom end of the curved rod 340 to move the curved rod 340 outward, and the curved rod 340 drives the sliding rod 320 to move outward, so that the three curved rods 340 move synchronously, and the ring is placed at the center position of the top surface of the fixed table 200. The three curved rods 340 are moved closer to the middle through the driving mechanism 500, and the three positioning wheels 342 clamp and position the ring so that the contact point between the positioning wheel 342 and the outer wall of the ring is located on the axial center line of the bottom end of the curved rod 340. The displacement distance of a sliding rod 320 at this time is obtained by the displacement detector 600, thereby obtaining the outer diameter of the ring.

[0035] See Figure 6As shown, the curved rod 340 includes a curved portion 344 located between the bottom and top ends of the curved rod 340, and an avoidance groove 230 is opened on the top surface of the fixed platform 200 at the position of the slide groove 1 210. The width of the avoidance groove 230 is not less than the rotation diameter of the curved portion 344 to prevent the curved portion 344 from interfering with the fixed platform 200 when rotating. A slider 330 is fixedly connected to the outer wall of one end of the slide rod 320, and the slider 330 is rotatably sleeved with the curved rod 340. The top end of the slider 330 is fixedly connected to the limiting plate 331, and the curved portion 344 is located above the slider 330 to limit the rotation of the curved rod 340. The distance between the bottom axis and the top axis of the curved rod 340 is equal to the radius of the positioning wheel 342, so that the positioning wheel 342 deflects around the axis of the bottom end of the curved rod 340, and at the same time facilitates the contact point between the positioning wheel 342 and the ring to be located on the axis of the bottom end of the curved rod 340.

[0036] See Figure 6-7 As shown, the inner wall of the arc-shaped through groove 410 is provided with a driving groove 420, and the outer wall of the bottom end of the curved rod 340 is fixedly sleeved with a rubber wheel 341. The rubber wheel 341 contacts the arc-shaped inner wall of the driving groove 420 near the center of the driving disk 400. The bottom and top ends of the rubber wheel 341 are both provided with a sliding sleeve 343. The sliding sleeve 343 is rotatably sleeved with the curved rod 340, and the sliding sleeve 343 is slidably connected to the inner wall of the adjacent arc-shaped through groove 410. The depths of the two sides of the driving groove 420 are different, so that the rubber wheel 341 can be 1 is in contact with the inner wall of one side of the driving groove 420. When the driving disk 400 rotates forward, the arc-shaped through groove 410 squeezes the sliding sleeve 343 to move the curved rod 340 outward, and the curved rod 340 drives the sliding rod 320 to move outward. When the bottom end of the curved rod 340 moves along the arc-shaped through groove 410, the friction between the inner wall of the driving groove 420 and the rubber wheel 341 drives the curved rod 340 to rotate half a circle in the opposite direction, thereby causing the positioning wheel 342 to deflect to a position on the side where the axis of the bottom end of the curved rod 340 is close to the center of the fixed platform 200.

[0037] See Figure 3 and 9As shown, the driving mechanism 500 includes a fixed disk 510, a cylinder 511 is fixedly connected to the center of the top surface of the fixed disk 510, the bottom end of the fixed disk 510 is fixedly connected to the top surface of the fixed plate 100, the driving disk 400 is rotatably sleeved with the cylinder 511, the top end of the cylinder 511 is fixedly connected to the bottom end of the fixed platform 200, an arc-shaped chute 520 is opened on one side of the top surface of the fixed disk 510, a threading hole 530 is opened at one end of the arc-shaped chute 520, one end of the threading hole 530 is communicated with the annular outer wall of the fixed disk 510, and the inner portion of the arc-shaped chute 520 is connected to the outer wall of the fixed disk 510. The wall is slidably connected with a fixed block 2 560, and a spring 2 580 is fixedly connected between the fixed block 2 560 and the inner wall of one end of the arc-shaped slide 520. A fixed block 1 550 is provided on one side of the fixed block 2 560, and the fixed block 1 550 is slidably connected to the inner wall of the arc-shaped slide 520. The top of the fixed block 1 550 is fixedly connected to the bottom surface of the driving disk 400. A spring 1 570 is fixedly connected between the fixed block 1 550 and the fixed block 2 560. The spring 1 570 and the spring 2 580 are both slidably connected to the arc-shaped slide 520. One end of the fixed block 2 560 is fixedly connected to the inner wall of the arc-shaped slide 520. The outer wall is fixed with a pull rope 540, one end of the pull rope 540 passes through the threading hole 530 and extends to the outside of the fixed disk 510. When the other end of the pull rope 540 is pulled, the pull rope 540 pulls the fixed block 2 560 toward one end of the arc-shaped slide groove 520 to deflect and slide, so that the spring 2 580 is compressed. The movement of the fixed block 2 560 causes the spring 1 570 to recover from the compressed state first and then be stretched. The fixed block 2 560 pulls the fixed block 1 550 through the spring 1 570, thereby driving the drive disk 400 to rotate forward. The setting of spring 2 570 enables the driving disk 400 to still pull the pull rope 540 after it stops, which facilitates the squeezing contact between the positioning wheel 342 and the ring. The top surface of the fixed plate 100 is located on one side of the fixed disk 510 and is rotatably connected to the winding wheel 590. The top surface of the winding wheel 590 is fixed with a handle. One end of the pull rope 540 is wrapped and fixed with the winding wheel 590, which facilitates pulling the pull rope 540. Two support legs 110 are fixed to the top position of the bottom surface of the fixed plate 100, so that the fixed plate 100 can be placed at an angle for easy observation and operation.

[0038] Working principle: When in use, initially, the top ends of the three curved rods 340 are located close to each other. When the outer diameter of the ring needs to be measured, the reel 590 is rotated by the handle, and the reel 590 reels the other end of the pull rope 540, so that the pull rope 540 pulls the fixed block 2 560 toward one end of the arc-shaped slide groove 520 to deflect and slide, so that the spring 2 580 is compressed. The movement of the fixed block 2 560 causes the spring 1 570 to recover from the compressed state first and then be stretched. The fixed block 2 560 pulls the fixed block 1 550 through the spring 1 570, thereby driving the drive disk 400 to rotate forward. When the driving disk 400 rotates forward, the arc-shaped slot 410 squeezes the sliding sleeve 343, causing the curved rod 340 to move outward, and the curved rod 340 drives the sliding rod 320 to move outward. When the bottom end of the curved rod 340 moves along the arc-shaped slot 410, the friction between the inner wall of the driving slot 420 and the rubber wheel 341 drives the curved rod 340 to rotate half a circle in the opposite direction, thereby causing the positioning wheel 342 to deflect to a position where the axis of the bottom end of the curved rod 340 is close to the center of the fixed platform 200. The limiting plate 331 blocks the curved portion 344, and the curved rod 340 stops rotating. The rubber wheel 341 slips on the inner wall of the driving slot 420.

[0039] The ferrule is placed at the center of the top surface of the fixed platform 200, and the handle is released. The elastic force of the second spring 580 is released, and the second fixed block 560 and the first spring 570 are pushed, so that the first spring 570 is compressed, and then the fixed block 550 is squeezed to drive the driving plate 400 to rotate in the opposite direction. The three curved rods 340 move closer to the center, and at the same time, the curved rod 340 rotates half a circle in the forward direction, so that the positioning wheel 342 moves to the side of the bottom end of the curved rod 340 away from the center of the fixed platform 200. Then, the curved rods 340 continue to move closer to each other, and the three positioning wheels 342 clamp and position the ferrule so that the contact point between the positioning wheel 342 and the outer wall of the ferrule is located on the axis center line of the bottom end of the curved rod 340. The displacement distance of the sliding rod 320 at this time is obtained by the displacement detector 600, thereby obtaining the outer diameter of the ferrule.

[0040] When measuring the inner diameter of the ferrule, when the three curved rods 340 are close to each other, the ferrule is placed outside the three positioning wheels 342. The winding wheel 590 is rotated by the handle to move the three curved rods 340 outward. The positioning wheels 342 are deflected to the side close to the center of the fixed platform 200 and then contact the inner wall of the ferrule. The three positioning wheels 342 tension and support the ferrule so that the contact point between the positioning wheels 342 and the inner wall of the ferrule is located on the axis of the bottom end of the curved rod 340, thereby obtaining the inner diameter of the ferrule.

[0041] By setting the curved rod 340 and the positioning wheel 342, when measuring the inner diameter and outer diameter of the ring, the contact points of the positioning wheel 342 and the ring are both located on the axis line of the bottom end of the curved rod 340, thereby realizing the measurement of the inner and outer diameters of the ring, which is convenient for use.
