Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub positioning, in particular to a positioning fixture for automobile wheel hub calendering. Background Art

[0002] The automobile wheel hub is the part of the center of the wheel where the axle is installed, which is often called the "wheel rim" or "steel rim". The wheel hub is easily stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, resulting in safety hazards. Therefore, special attention should be paid to the maintenance of the wheel hub. Steel rolling processing refers to the steel rolling industry, including steel plates, steel sections, strip steel, wire rods, hot and cold thin plates, and the steel industry known to include continuous casting and rolling processes. When the wheel hub of an automobile is rolled, a positioning fixture is required to fix it. However, the positioning fixture currently used for the rolling processing of automobile wheels is difficult to rotate the clamped wheel hub during use, making it difficult to adjust the orientation. The inconvenience in adjusting the processing orientation makes the application very inflexible and inefficient.

[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a positioning fixture for automobile wheel hub calendering to solve the shortcomings of the prior art. Utility Model Content

[0004] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a positioning fixture for automobile wheel hub calendering. Through the rotation of the rotating screw in the positioning mechanism, the movable sleeves of two groups of different threaded mechanisms can move relative to and away from each other, thereby driving the clamping arm to clamp the wheel hub. At the same time, after the clamping is completed, the rotating ring is rotated in the fixed ring by operating the operating handle installed on the rotating ring. At this time, the moving groove opened on the fixed ring provides a rotation space for the overall rotation of the rotating screw in the positioning mechanism. The rotating ring drives the wheel hub clamped by the positioning mechanism to rotate, thereby improving the flexibility of the wheel hub clamping processing.

[0005] The above-mentioned purpose of the utility model is achieved through the following technical means.

[0006] Provided is a positioning fixture for automobile wheel hub calendering, comprising a supporting base, a supporting frame mounted on the supporting base, a fixed back plate mounted on the supporting frame, a circular ring groove provided on the fixed back plate, a fixed circular ring mounted on the fixed back plate, a movable groove provided on the fixed circular ring, a rotating circular ring rotatably mounted inside the fixed circular ring, and a positioning mechanism mounted inside the rotating circular ring:

[0007] The positioning mechanism includes a mounting part, which is mounted inside the rotating ring. The mounting part is provided with an open groove. A rotating screw is mounted inside the mounting part. One end of the rotating screw is connected to the inside of the mounting part. The other end of the rotating screw is connected to a driving motor. A buffer block is integrally formed at the center of the rotating screw. Two sets of movable sleeves are mounted on the rotating screw. A clamping arm is integrally formed and connected to the movable sleeve.

[0008] Specifically, the two groups of movable sleeves are provided with threaded mechanisms cooperating with the rotating lead screws, and the threaded structures inside the two groups of movable sleeves are respectively a positive threaded structure and a reverse threaded structure.

[0009] Specifically, two groups of clamping arms pass through the open slots, and clamping claws are installed on the top ends of the two groups of clamping arms.

[0010] Specifically, an anti-collision bushing is installed at one end of the clamping arm close to the clamping claw.

[0011] Specifically, an operating handle is installed on the back of the rotating ring, and the operating handle passes through a circular groove provided on the fixed back plate.

[0012] The utility model enables the movable sleeves of two groups of different threaded mechanisms to move relative to and away from each other through the rotation of the rotating screw in the positioning mechanism, thereby driving the clamping arm to clamp the wheel hub. At the same time, after the clamping is completed, the rotating ring is rotated in the fixed ring by operating the operating handle installed on the rotating ring. At this time, the movable groove provided on the fixed ring provides a rotation space for the overall rotation of the rotating screw in the positioning mechanism. The rotating ring drives the wheel hub clamped by the positioning mechanism to rotate, thereby improving the flexibility of the wheel hub holding processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The utility model is further described in conjunction with the following embodiments.

[0039] Embodiment 1:

[0040] like Figure 1-5 As shown, a positioning fixture for automobile wheel hub calendering includes a supporting base 1, a supporting frame 2 is installed on the supporting base 1, a fixed back plate 3 is installed on the supporting frame 2, a circular ring groove 4 is opened on the fixed back plate 3, a fixed circular ring 5 is installed on the fixed back plate 3, a movable groove 6 is opened on the fixed circular ring 5, a rotating circular ring 7 is rotatably installed inside the fixed circular ring 5, and a positioning mechanism 8 is installed inside the rotating circular ring 7.

[0041] When in use, the support base 1 and the support frame 2 are installed on the fixed back plate 3 to provide support. A fixed ring 5 is installed on the fixed back plate 3. At the same time, a ring groove 4 smaller than the inner diameter of the fixed ring 5 is opened on the fixed back plate 3. A rotating ring 7 is installed inside the ring groove 4. At the same time, the rotating ring 7 can rotate inside the fixed ring 5. The rotating ring 7 is movably sleeved inside the fixed ring 5. A positioning mechanism 8 is installed inside the rotating ring 7 to clamp and fix the wheel hub to be processed. The positioning mechanism 8 cooperates with the rotating ring 7 and the fixed ring 5 to rotate the wheel hub after clamping and fixing, which is convenient for subsequent wheel hub processing.

[0042] The positioning mechanism 8 includes a mounting portion 9, which is mounted inside the rotating ring 7. The mounting portion 9 is provided with an open groove 10. A rotating screw 11 is installed inside the mounting portion 9. One end of the rotating screw 11 is connected to the inside of the mounting portion 9. The other end of the rotating screw 11 is connected to a driving motor 12. A buffer block 13 is integrally formed at the center of the rotating screw 11. Two sets of movable sleeves 14 are installed on the rotating screw 11, and a clamping arm 15 is integrally formed and connected to the movable sleeve 14.

[0043] The mounting portion 9 is provided with a cavity inside, the mounting portion 9 is installed inside the rotating ring 7, and the mounting portion 9 has the same inner diameter length as the rotating ring 7. The rotating screw 11 installed inside the mounting portion 9 can be powered and rotated by a driving motor 12 installed outside. The driving motor 12 is a prior art. The driving motor 12 is a reciprocating motor that can adjust the rotation direction. The driving motor 12 can drive the two sets of movable sleeves 14 installed thereon to move during rotation in different directions. The two sets of movable sleeves 14 are provided with threaded mechanisms that cooperate with the rotating screw 11. The internal thread structures of the two sets of movable sleeves 14 are respectively a positive thread structure and a reverse thread structure. Since the positive thread structure and the reverse thread structure in the two sets of movable sleeves 14 are different, the two sets of movable sleeves 14 are When the screw 11 rotates, the two groups of movable sleeves 14 move relative to each other or toward each other. When the two groups of movable sleeves 14 move relative to each other, the buffer block 13 installed in the center of the screw 11 can prevent the two groups of movable sleeves 14 from colliding with each other, thereby improving safety. When the movable sleeve 14 drives the one-piece clamping arm 15 to move relative to each other or toward each other, the clamping arm 15 can move inside the opening groove 10 of the mounting portion 9. During the movement, the clamping claw 16 installed on the clamping arm 15 can clamp the wheel hub to be processed. The setting of the clamping claw can prevent the wheel hub from rotating and falling off. At the same time, an anti-collision bushing 17 is installed at one end of the clamping arm 15 close to the clamping claw 16. The anti-collision bushing 17 can prevent the clamping claw 16 and the clamping arm 15 from scratching the wheel hub when clamping.

[0044] An operating handle 18 is installed on the back of the rotating ring 7. The operating handle 18 passes through the annular groove 4 opened on the fixed back plate 3. After the positioning mechanism 8 clamps the wheel hub, the operating handle 18 is controlled to rotate in the annular groove 4. At the same time, the operating handle 18 can drive the rotating ring 7. The positioning mechanism 8 installed inside the rotating ring 7 will also rotate inside the fixed ring 5 as the rotating ring 7 rotates. The wheel hub clamped on the positioning mechanism 8 rotates accordingly, thereby improving the flexibility of the wheel hub during processing.

[0045] During the production process, through the rotation of the rotating screw 11 in the positioning mechanism 8, the movable sleeves 14 of the two groups of different threaded mechanisms can move relative to and away from each other, thereby driving the clamping arm 15 to clamp the wheel hub. At the same time, after the clamping is completed, the rotating ring 7 is rotated in the fixed ring 5 by operating the operating handle 18 installed on the rotating ring 7. At this time, the movable groove 6 opened on the fixed ring 5 provides a rotation space for the overall rotation of the rotating screw 11 in the positioning mechanism 8. The rotating ring 7 drives the wheel hub clamped by the positioning mechanism 8 to rotate, thereby improving the flexibility of the wheel hub holding processing.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
