Description

Technical Field

[0001] This utility model relates to the field of lathe fixture technology, specifically a fixture for a wheel hub vertical lathe. Background Technology

[0002] In recent years, with the continuous development of my country's automobile and transportation industries, automobiles have become an indispensable means of transportation for people's work, study, and life. The pursuit of driving comfort is also one of the increasingly important performance indicators for automobiles. Wheel hubs are an important component of automobiles, and their dynamic balance directly affects driving comfort. When a car is traveling at high speed and the wheels are rotating rapidly, the wheel hub becomes dynamically unbalanced due to uneven mass distribution during manufacturing. Drivers directly experience wheel vibration and steering wheel vibration at high speeds. Therefore, vertical lathes are currently used in the production process to machine and grind the burrs from the wheel hubs.

[0003] The existing fixtures on vertical lathes are usually symmetrical fixtures. When clamping and fixing round and smooth-edged wheel hubs, there are not enough clamping points and they are prone to movement, which leads to excessive turning force and problems such as product displacement and uneven edges.

[0004] Therefore, it is necessary to provide a new fixture for a wheel hub vertical lathe to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fixture for a wheel hub vertical lathe.

[0006] The fixture for a vertical lathe for a wheel hub provided by this utility model includes:

[0007] The base has a clamping frame on its top, and there are multiple sets of clamping frames.

[0008] The clamping block has threaded holes on the top of multiple clamping frames, threaded rods are engaged inside the multiple threaded holes, clamping blocks are rotatably connected to the inner side of the multiple threaded rods, telescopic grooves are opened on the inner side of the multiple clamping frames, and the clamping blocks are slidably connected inside the telescopic grooves.

[0009] Preferably, the top of the base is provided with adjustment holes, and multiple sets of adjustment holes are provided. The clamping frame can be fixed to prevent shaking through the adjustment holes.

[0010] Preferably, each of the multiple sets of adjustment holes is movably connected to a fixing bolt, and the bottom end of each of the multiple sets of fixing bolts is engaged with a fixing nut. The clamping frame can be fixed by the fixing bolts and fixing nuts.

[0011] Preferably, the bottom of each of the multiple clamping frames is provided with an adjustment groove, and the top of each of the multiple fixing bolts passes through and is movably connected to the adjustment groove to the top, so that the position of the clamping frame can be adjusted through the adjustment groove.

[0012] Preferably, the top of each of the multiple clamping frames is fixedly connected to a side plate, and multiple sets of side plates are provided. The side plates can protect the sides of the clamping frames.

[0013] Preferably, a connecting sleeve is fixedly connected to the bottom of the base, and the clamp can be fixed by the connecting sleeve.

[0014] Preferably, a rotating handle is fixedly connected to the outer side of the threaded rod, and the threaded rod can be rotated by the rotating handle.

[0015] Preferably, a buffer rod is fixedly connected to the top of the base. Multiple sets of buffer rods are provided, and buffer blocks are fixedly connected to the top of each set of buffer rods. The buffer blocks can prevent the wheel hub from falling and damaging the clamp.

[0016] Compared with related technologies, the jig for the wheel hub vertical lathe provided by this utility model has the following advantages:

[0017] This utility model provides a fixture for a wheel hub vertical lathe;

[0018] This utility model can clamp and fix the wheel hub using the clamping blocks. When it is necessary to clamp and fix the wheel hub, the wheel hub can be placed on the fixture manually. By manually turning the rotating handle, the threaded rod is driven to mesh and rotate inside the threaded hole. The clamping block connected to the inner side of the threaded rod moves inward inside the telescopic groove. The movement of multiple sets of telescopic clamping blocks simultaneously clamps and fixes the three points of the wheel hub, thereby achieving clamping and fixing of the wheel hub to facilitate subsequent processing.

[0019] This invention allows for adjustment of the clamping frame's position using a fixed bolt. Before clamping and fixing the wheel hub, the clamping frame's position can be adjusted by rotating the fixing nut with a tool to disengage the fixing nut and fixing bolt, depending on the wheel hub's diameter. The clamping frame can then be manually pulled, allowing the fixing bolt to slide within the adjustment groove, thus adjusting its position. The fixing nut can then be rotated in the opposite direction to engage with one end of the fixing bolt, and the clamping frame can be re-locked by locking the fixing bolt with the fixing nut. This allows for adjustment of the clamping frame's position according to the wheel hub's diameter. Attached Figure Description

The multiple clamping blocks 14 are slidably connected to the inside of the telescopic grooves 11.

[0029] It should be noted that when clamping and fixing the wheel hub, the wheel hub can be manually placed on the clamp. By manually rotating the rotating handle 13, the threaded rod 12 is driven to engage and rotate inside the threaded hole 15. This causes the clamping block 14, which is rotated inside the threaded rod 12, to move inward inside the telescopic groove 11. The movement of multiple sets of telescopic clamping blocks 14 simultaneously clamps and fixes the wheel hub at three points, thus facilitating subsequent processing. Before clamping and fixing the wheel hub, the position of the clamping frame 8 can be adjusted according to the diameter of the wheel hub by rotating the fixing nut 7 with a tool to disengage the fixing nut 7 and the fixing bolt 6. The clamping frame 8 can be manually pulled, and the fixing bolt 6 can slide inside the adjustment groove 9 to adjust its position. The fixing nut 7 can then be rotated in the opposite direction to engage with one end of the fixing bolt 6. The clamping frame 8 can be re-locked by locking the fixing bolt 6 with the fixing nut 7, thus adjusting the position of the clamping frame according to the diameter of the wheel hub.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The top of the base 1 is provided with adjustment holes 5. There are multiple sets of adjustment holes 5. The clamping frame 8 can be fixed by the adjustment holes 5 to prevent shaking.

[0031] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 Each of the multiple sets of adjustment holes 5 is movably connected with a fixing bolt 6, and the bottom end of each of the multiple sets of fixing bolts 6 is engaged with a fixing nut 7.

[0037] The working principle of the fixture for the wheel hub vertical lathe provided by this utility model is as follows:

[0038] When using the device, firstly, when it is necessary to clamp and fix the wheel hub, the wheel hub can be manually placed on the clamp. By manually rotating the handle 13, the threaded rod 12 is driven to engage and rotate inside the threaded hole 15. This causes the clamping block 14, which is rotated inside the threaded rod 12, to move inward inside the telescopic groove 11. The movement of multiple sets of telescopic clamping blocks 14 simultaneously clamps and fixes the three points of the wheel hub, thereby clamping and fixing the wheel hub for subsequent processing. Before clamping and fixing the wheel hub, the position of the clamping frame 8 can be adjusted according to the diameter of the wheel hub by rotating the fixing nut 7 with a tool to disengage the fixing nut 7 and the fixing bolt 6. The clamping frame 8 can be manually pulled, and the fixing bolt 6 can slide inside the adjustment groove 9 to adjust the position of the clamping frame 8. The fixing nut 7 can be rotated in the opposite direction with a tool to engage and rotate into one end of the fixing bolt 6.
