Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a positioning device for processing bearing rings. Background Technology

[0002] Bearing rings are an important component of bearings. After the bearing rings are manufactured, their inner walls usually need to be ground. Therefore, positioning devices are usually used to position the bearing rings to facilitate subsequent grinding.

[0003] Chinese patent document CN217860732U discloses a positioning device for machining bearing rings, including a base and a lifting rod. The upper part of the lifting rod is provided with a limit ring, and the inner side of the limit ring is provided with an installation groove. An upper mounting block is fixedly installed on the rear side of the limit ring. An upper movable shaft is movably installed inside the upper mounting block. An actuating rod is movably connected to the upper mounting block through the upper movable shaft. A lower movable shaft is movably installed on the lower part of the actuating rod, and a lower mounting block is provided on the side of the lower movable shaft.

[0004] In the above solution, the bearing race is positioned by wrapping it. However, the size of the limiting ring is fixed, which makes it impossible to fix bearing races of different sizes. Furthermore, wrapping the outside of the bearing race with the limiting ring will hinder the machining of the outside of the bearing race, resulting in a narrow range of applications.

[0033] Example 1

[0034] like Figure 1-4 As shown, the positioning device for machining bearing rings proposed in this utility model includes a worktable 1, a mounting strip 2, a drive assembly, a positioning rod, and a limiting assembly;

[0035] There are two mounting strips 2, which are symmetrically installed on the top of the workbench 1 to support the bearing rings during use. The bottom ends of the two mounting strips 2 are provided with adjustment components that extend to the inside of the workbench 1 and can move the two mounting strips 2 relative to each other or away from each other during use.

[0036] There are four positioning rods. Two positioning rods are inserted into each set on the mounting strip 2, and the two positioning rods in each set are symmetrically arranged in the middle of the mounting strip 2 according to the center of the mounting strip 2.

[0037] The limiting component is set on the side of the mounting strip 2 and extends to the middle of the mounting strip 2 and is connected to the positioning rod. It is used to limit the connection between the positioning rod and the mounting strip 2 during use, so that the positioning rod and the mounting strip 2 can be detachably connected, and the position of the positioning rod on the mounting strip 2 can be adjusted so that the positioning rod can position bearing rings of different sizes.

[0038] The drive assembly is located at the bottom of the worktable 1 and connected to the adjustment assembly. It is used to drive the adjustment assembly to move the two mounting bars 2 synchronously relative to or opposite to each other during use.

[0039] In this embodiment, the positioning rod is adjusted on the mounting strip 2 according to the bearing ring size, and the positioning rod is fixed on the mounting strip 2 by the limiting component. At the same time, the drive component is started and the adjustment component is driven to operate, so that the adjustment component moves the two mounting strips 2 synchronously relative to each other or in opposite directions at the top of the worktable 1 until the distance between the two mounting strips 2 matches the bearing ring size. The drive component is then turned off, and the bearing ring is placed on the top of the two mounting strips 2, ensuring that it is located between or on the outside of the four positioning rods. The drive component is restarted, so that the movement of the mounting strip 2 pushes the positioning rod to make close contact with the inner or outer wall of the bearing ring, thereby fixing the bearing ring on the top of the mounting strip 2. This ensures that the inner and outer sides of bearing rings of different sizes can be reliably fixed, ensuring that no displacement occurs during the processing.

[0040] Example 2

[0041] like Figure 3 As shown, the positioning device for processing bearing rings proposed in this utility model differs from that in Embodiment 1 in that the adjusting component includes a connecting rod 4, a first rotating seat 5, and a second rotating seat 13.

[0042] There are two first rotating seats 5 and two second rotating seats 13. The two first rotating seats 5 and the two connecting plates 3 are arranged symmetrically, and the orientation of the first rotating seats 5 and the second rotating seats 13 is arranged at right angles. The middle part of the two first rotating seats 5 extends to the top of the worktable 1 and connects with the mounting strip 2. The bottom of the middle part of the two second rotating seats 13 extends to the bottom of the worktable 1 and connects with the drive assembly.

[0043] There are four connecting rods 4, which are all arranged between the two first rotating seats 5 and the two connecting plates 3. The two ends of the connecting rods 4 are rotatably connected to the first rotating seats 5 and the second rotating seats 13, respectively.

[0044] In this embodiment, the two second rotating seats 13 are connected to the driving component, so that the driving component drives the two second rotating seats 13 to move relative to each other or in opposite directions. This causes the two ends of the connecting rod 4 to rotate on one side of the second rotating seat 13 and the first rotating seat 5, respectively, thereby driving the first rotating seat 5 to move. Finally, the two mounting strips 2 are synchronously displaced relative to each other or in opposite directions, so that the position of the two mounting strips 2 can be adapted to bearing rings of different sizes.

[0045] Example 3

[0046] like Figure 4 As shown, the positioning device for processing bearing rings proposed in this utility model differs from that in Embodiment 1 in that the positioning rod includes a protective sleeve 6 and a rod body 7.

[0047] The rod 7 is inserted into the top of the mounting strip 2;

[0048] The protective sleeve 6 is fitted onto the top of the pole 7 and contacts the upper surface of the mounting strip 2.

[0049] In an optional embodiment, multiple mounting holes 8 are symmetrically arranged at the top of the mounting hole 8 according to the center of the mounting strip 2, and the spacing between the multiple mounting holes 8 is the same. The end face of the rod 7 is rectangular. When the rod 7 and the mounting strip 2 are installed together, the bottom end of the rod 7 is fitted into the mounting hole 8. This is used to adjust the position of the rod 7 during use, so that the rod 7 can use different sized collars, and to generate an interaction force between the rod 7 and the inner wall of the mounting hole 8, so as to prevent the rod 7 from rotating.

[0050] In this embodiment, by setting a mounting hole 8 at the top of the mounting strip 2 and inserting the rod 7 into the inner side of the mounting hole 8, and by making the end face of the rod 7 rectangular, there is an interaction force between the rod 7 and the inner wall of the mounting hole 8, ensuring that the rod 7 will not rotate when subjected to lateral force during the bearing ring processing, thereby maintaining the reliability of positioning. The protective sleeve 6 is made of wear-resistant material and is tightly fitted on the top of the rod 7, with its lower end face in contact with the upper end face of the mounting strip 2, reducing damage to the surface of the sleeve.

[0051] Example 4

[0052] like Figure 4 As shown, the positioning device for processing bearing rings proposed in this utility model differs from that in Embodiment 1 in that the limiting component includes a connecting plate 3 and a limiting rod 14.

[0053] The connecting plate 3 is located on the side of the mounting strip 2;

[0054] The limiting rod 14 is set on the side of the connecting plate 3, and its end is inserted into the side of the mounting strip 2 and extends to the inside of the mounting hole 8 to connect with the rod body 7. The limiting rod 14 and the mounting hole 8 are arranged in a one-to-one correspondence.

[0055] In an optional embodiment, a slot 15 is provided on the bottom side of the rod 7, and the end of the limiting rod 14 is inserted into the slot 15. It should be noted that the end of the limiting rod 14 is provided with an inclined surface 16, which is used to move the limiting rod 14 to the outside of the mounting strip 2 through the inclined surface 16 when the rod 7 is moved to the inside of the mounting hole 8, making the installation of the rod 7 more convenient, and allowing the limiting rod 14 to be inserted into the slot 15 to limit the rod 7, so that the rod 7 is fixed in the mounting hole 8.

[0056] In an optional embodiment, the side of the mounting strip 2 is provided with a slide rod 10 that extends through the connecting plate 3 to the other side of the connecting plate 3. A spring 9 connected to the other side of the connecting plate 3 is sleeved on the outside of the slide rod 10. When in use, the slide rod 10 limits one end of the spring 9, so that the spring 9 drives the connecting plate 3 to be tightly attached to the side of the mounting strip 2 by elastic force, thereby improving the stability of the connection between the limiting rod 14 and the rod body 7.

[0057] In this embodiment, the limiting rod 14 is moved to the side of the mounting strip 2 by the connecting plate 3. At the same time, the connecting plate 3 drives the spring 9 to compress on the slide rod 10, so that the end of the limiting rod 14 disengages from the slot 15 at the bottom of the rod body 7 and separates the rod body 7 from the mounting hole 8. The limiting rod 14 is reset by the elastic force of the spring 9, and the rod body 7 is adjusted to the desired position in the mounting hole 8. When the bottom end of the rod body 7 is inserted into the mounting hole 8, the bottom end of the rod body 7 drives the limiting rod 14 to move outward of the mounting strip 2 through the inclined surface 16, and compresses the spring 9 again until the rod body 7 is in place. The slot 15 and the limiting rod 14 are aligned, so that the limiting rod 14 is reset by the elastic force of the spring 9 and inserted into the slot 15. Thus, the rod body 7 is fixed in the mounting hole 8, making the position adjustment of the rod body 7 more convenient and the stability higher.

[0058] Example 5

[0059] like Figure 1-3 As shown, the positioning device for processing bearing rings proposed in this utility model differs from that in Embodiment 1 in that the driving component includes a bidirectional lead screw 11 and a motor 12.

[0060] The bidirectional lead screw 11 is rotatably mounted on the bottom end of the worktable 1, and both ends are threadedly connected to the second rotating seat 13.

[0061] The motor 12 is mounted below the worktable 1 via a bracket (not shown in the figure) and is connected to the bidirectional lead screw 11 for transmission. In use, the motor 12 can be connected to the bidirectional lead screw 11 via a reducer or a worm gear.

[0062] In this embodiment, the motor 12 drives the bidirectional lead screw 11 to rotate at the bottom of the worktable 1, and the bidirectional lead screw 11 drives two second rotating seats 13 to move relative to or away from each other on the worktable 1 through the thread. This causes the second rotating seats 13 to move the end of the connecting rod 4 while rotating both ends of the connecting rod 4 on the first rotating seat 5 and the second rotating seat 13. This causes the second rotating seat 13 to move the two first rotating seats 5 relative to or away from each other through the connecting rod 4, thereby causing the mounting strip 2 to move synchronously with the first rotating seat 5 to support bearing rings of different sizes, and causing the protective sleeve 6 to drive the rod body 7 to limit the rings on the mounting strip 2.

[0063] In this invention, the connecting plate 3 moves the limiting rod 14 to the side of the mounting strip 2. Simultaneously, the connecting plate 3 compresses the spring 9 on the sliding rod 10, causing the end of the limiting rod 14 to disengage from the slot 15 at the bottom of the rod body 7, separating the rod body 7 from the mounting hole 8. The limiting rod 14 is then reset by the spring force of the spring 9, and the rod body 7 is adjusted to the desired position in the mounting hole 8. When the bottom end of the rod body 7 is inserted into the mounting hole 8, the bottom end of the rod body 7, through the inclined surface 16, moves the limiting rod 14 to the outside of the mounting strip 2, compressing the spring 9 again until the rod body 7 is in place. The slot 15 aligns with the limiting rod 14, causing the limiting rod 14 to reset again by the spring force of the spring 9 and insert into the slot 15, thus fixing the rod body 7 in the mounting hole 8. The starting motor 12 drives the bidirectional lead screw 11 to rotate at the bottom of the worktable 1, and the bidirectional lead screw 11 drives two... The second rotating seat 13 moves relative to or away from each other on the worktable 1, thereby causing the second rotating seat 13 to drive the end of the connecting rod 4 to move, while simultaneously rotating both ends of the connecting rod 4 on the first rotating seat 5 and the second rotating seat 13. This causes the second rotating seat 13 to move the two first rotating seats 5 relative to or away from each other through the connecting rod 4, thereby causing the mounting strip 2 to move synchronously with the first rotating seat 5, so that the spacing between the two mounting strips 2 is adapted to the bearing ring size. The motor 12 is turned off, and the bearing ring is placed on the top of the two mounting strips 2, ensuring that it is located between or outside the four rods 7. The motor 12 is restarted, so that the movement of the mounting strip 2 pushes the rod 7 to make the protective sleeve 6 tightly contact the inner or outer wall of the bearing ring, thereby causing the rod 7 to drive the protective sleeve 6 to fix the bearing ring on the top of the mounting strip 2, so that the inner and outer sides of bearing rings of different sizes can be reliably fixed, ensuring that no displacement occurs during processing.

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
