Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a wheel hub spinning machine. Background Technology

[0002] A wheel hub is a cylindrical metal component inside a car tire, centered on an axle, used to support the tire. Steel wheel hubs are gradually being replaced by aluminum alloy wheel hubs. Aluminum alloy wheel hubs are usually formed into a cylindrical shape using spinning technology. On the one hand, compared with traditional casting, it does not produce common problems in the traditional casting process such as sand holes, shrinkage cavities, and cracks, which can save raw materials and improve the yield of finished products. On the other hand, it makes the mechanical structure of the wheel hub more compact and stronger.

[0003] Existing wheel hub spinning machines fix the wheel hub blanks on a rotating base when spinning them. If the wheel hub blanks are placed at an angle that is tilted before processing, it may cause deformation during processing, or the blanks may not be firmly fixed during rotation, resulting in insufficient quality of the finished product. To address these issues, we propose a wheel hub spinning machine. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-3 In this embodiment of the present invention, a wheel hub spinning machine includes a processing chamber 1 and a wheel hub blank 7. A coarse spinning cutter 2 and a fine spinning cutter 5 are respectively arranged on opposite sides of the inner wall of the processing chamber 1. A top-mounting mechanism 3 and a correction mechanism 4 are arranged at the bottom of the processing chamber 1, and a top-aligning mechanism 6 is arranged at the top of the processing chamber 1. The top-aligning mechanism 6 includes a top block 603. The top-mounting mechanism 3 includes a bottom turntable 301 fixedly installed at the bottom of the processing chamber 1, and the bottom turntable 301 and the processing workpiece top seat 302 form a rotating connection. Next, the top mechanism 6 includes a top turntable 601 fixedly installed at the top of the inside of the processing chamber 1, and a top cylinder 602 is rotatably connected to the bottom of the top turntable 601. An annular baffle 604 is fixedly installed on the outer wall of the top block 603. When the top cylinder 602 is activated, the top block 603 and the processing workpiece top seat 302 abut against the wheel hub blank 7 and rotate. At the same time, the coarse rotary cutter 2 and the fine rotary cutter 5 begin to move and rotate to perform spinning processing on the wheel hub blank 7. A clamping mechanism 8 is provided inside the annular baffle 604.

[0024] Example 2

[0025] The top component mechanism 3 includes a workpiece top seat 302, the correction mechanism 4 includes a placement ring 402, the workpiece top seat 302 is located inside the placement ring 402, and elastic paddles 404 are evenly distributed on the upper surface of the placement ring 402. The wheel hub blank 7 is located between the top component block 603 and the workpiece top seat 302, and the upper end of the workpiece top seat 302 is frustum-shaped. Lifting rods 401 are fixedly installed on both sides of the placement ring 402, and an expansion rod 403 is provided inside the placement ring 402.

[0026] The difference from Example 1 is that: before use, the wheel hub blank 7 is placed on the placement ring 402 and fixed by the elastic paddle 404. The wheel hub blank 7 is in a horizontal state. The lifting rod 401 drives the wheel hub blank 7 to descend and makes the wheel hub blank 7 stuck on the processing part top seat 302 without causing angular deviation. At this time, the wheel hub blank 7 is disengaged from the elastic paddle 404. The placement ring 402 continues to descend and is expanded to a certain diameter by the expansion rod 403 to prevent interference with the rotation of the processing part top seat 302 during processing.

[0027] Example 3

[0028] The annular baffle 604 has a rod groove 606 inside, and the bottom end of the rod groove 606 has a vertically formed engagement groove 605 and a translation groove 607. The clamping mechanism 8 includes a power threaded rod 802 that is slidably connected inside the annular baffle 604. A pressure block 801 and a fixing plate 803 are respectively provided at both ends of the power threaded rod 802. A meshing threaded rod 805 is horizontally arranged inside the rod groove 606 via a bearing seat, and a sliding sleeve 806 is sleeved on the outer wall of the meshing threaded rod 805. Furthermore, a crank rod 807 is fixedly installed at the bottom of the sliding sleeve 806, the pressure block 801 and the engaging groove 605 form an engaging connection, the power threaded rod 802 and the fixed plate 803 form a rotatable connection, a spring 804 is fixedly connected between the fixed plate 803 and the annular baffle 604, the power threaded rod 802 and the meshing threaded rod 805 form a meshing connection, and the meshing threaded rod 805 and the sliding sleeve 806 form a rotatable connection, and a rubber head 808 is fixedly installed at the bottom of the crank rod 807.

[0029] The difference from Embodiment 1 is that: when the top cylinder 602 is activated, the pressure block 801 contacts the wheel hub blank 7 and drives the power threaded rod 802 to rise and rotate until the pressure block 801 engages with the engagement groove 605, the engagement threaded rod 805 rotates, the sliding sleeve 806 moves outward on the engagement threaded rod 805 and drives the crank rod 807 and the rubber head 808 to press against the inside of the wheel hub blank 7 to strengthen the fixation.

[0030] The working principle of this utility model is as follows: Before use, the wheel hub blank 7 is placed on the placement ring 402 and fixed by the elastic lever 404. The wheel hub blank 7 is in a horizontal state. The lifting rod 401 drives the wheel hub blank 7 to descend and lock the wheel hub blank 7 onto the workpiece top seat 302 without causing angular deviation. At this time, the wheel hub blank 7 is released from the elastic lever 404. The placement ring 402 continues to descend and is expanded to a certain diameter by the expansion rod 403 to prevent interference with the rotation of the workpiece top seat 302 during processing. The top cylinder 602... Upon startup, the pressure block 801 contacts the wheel hub blank 7 and drives the power threaded rod 802 to rise and rotate until the pressure block 801 engages with the engagement groove 605. The engagement threaded rod 805 rotates, and the sliding sleeve 806 moves outward on the engagement threaded rod 805, driving the crank rod 807 and the rubber head 808 to press against the inside of the wheel hub blank 7 for reinforcement. The top block 603 and the processing top seat 302 press against the wheel hub blank 7 and rotate. At the same time, the coarse turning cutter 2 and the fine turning cutter 5 begin to move and rotate, performing spinning processing on the wheel hub blank 7.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This method of description is merely for clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in the various embodiments can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
