Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub fixing, in particular to a quick-fixing positioning chuck for a wheel hub. Background Technique

[0002] In modern society, cars have entered thousands of households. During the use of cars, car damage often occurs, and the most common situation is that the tires on the outer side of the car wheels are punctured. When repairing the car wheels, the wheels need to be removed and then fixed outside the machine tool. The traditional fixing method is to place the wheel hub outside the rotating shaft of the machine tool and fix it by passing multiple screws through the screw holes inside the wheel hub. This method not only has low fixing efficiency but also is inconvenient for disassembly. Because once the screws are tightened for fixing, it will inevitably lead to inconvenient subsequent disassembly. And once the screws are not tightened, the fixing quality is not good at this time. Therefore, a quick-fixing positioning chuck for a wheel hub is proposed for the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick-fixing positioning chuck for a wheel hub to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] As an optional scheme of a quick-fixing positioning chuck for a wheel hub of the utility model, wherein: a quick-fixing positioning chuck for a wheel hub includes a machine tool, a chuck assembly and a wheel hub,

[0006] The other end of the output shaft of the machine tool is provided with a chuck assembly, and a wheel hub is arranged outside the chuck assembly;

[0007] The chuck assembly includes a connecting plate, a motor and a rotating shaft. One side of the connecting plate is connected to the output shaft of the machine tool. The center of the inside of the connecting plate is fixedly connected with a motor. The end of the main shaft of the motor is fixedly connected with a rotating shaft. The other end of the rotating shaft is rotatably connected to the connecting plate. A threaded ring is spirally connected to the outside of the rotating shaft. The outside of the threaded ring is fixedly connected with evenly distributed mounting brackets, and the outside of each mounting bracket is rotatably connected with a support rod. The other ends of the support rods are all rotatably connected with clamping blocks, and the outside of the clamping blocks is slidably connected to the connecting plate.

[0008] As an optional scheme of a quick-fixing positioning chuck for a wheel hub of the utility model, wherein: a storage battery is also installed inside the connecting plate, and a plug plate detachably connected to the connecting plate is arranged on one side of the storage battery.

[0009] In modern society, cars have entered thousands of households. During the use of cars, car damage often occurs, and the most common situation is that the tires on the outer side of the car wheels are punctured. When repairing the car wheels, the wheels need to be removed and then fixed outside the machine tool. The traditional fixing method is to place the wheel outside the rotating shaft of the machine tool and fix it by passing multiple screws through the screw holes inside the wheel. This method not only has low fixing efficiency but also is inconvenient for disassembly. Because once the screws are tightened for fixing, it will inevitably cause inconvenience for subsequent disassembly. And once the screws are not tightened, the fixing quality is not good at this time. When the power is turned on during use and the wheel needs to be repaired, place the wheel outside the gradient block on one side of the chuck. By starting the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the threaded ring to move, the threaded ring drives the mounting bracket to move, so that the support rod drives the chuck to move. Multiple chucks move outwards, and then the gradient block outside the chuck can be in close contact with the inner ring of the wheel, so as to achieve the purpose of quickly fixing the wheel. And when disassembling the wheel, reverse the motor, and at this time drive the chuck to move towards the center, then the quick disassembly of the wheel can be realized.

[0010] As an alternative solution of a kind of quick fixing and positioning chuck for a wheel hub of the present utility model, wherein: strip-shaped chutes are opened on both sides of the chuck, and the chuck is slidably connected with the connecting plate through the strip-shaped chutes.

[0011] As an alternative solution of a kind of quick fixing and positioning chuck for a wheel hub of the present utility model, wherein: grooves are opened inside the connecting plate, and support rods are arranged inside the grooves.

[0012] As an alternative solution of a kind of quick fixing and positioning chuck for a wheel hub of the present utility model, wherein: the number of the grooves is four groups, and the outer side of the support rod is in contact with the inner wall of the groove.

[0013] When the chuck moves, the arranged strip-shaped chutes can ensure that it moves along the specified moving track, ensuring the stable movement of the chuck, and the setting of the grooves can ensure the stable movement of the support rod and prevent it from rotating.

[0014] As an alternative solution of a kind of quick fixing and positioning chuck for a wheel hub of the present utility model, wherein: the side of the chuck facing away from the connecting plate is gradient-shaped.

[0015] Multiple gradient blocks outside the chuck can ensure the outward expansion and fixation of the wheel hub, and at the same time can also perform outward expansion and fixation on other objects, expanding the scope of use.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] When the utility model is in use, the wheel hub is placed outside the gradient block on one side of the chuck. By starting the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the threaded ring to move, and the threaded ring drives the mounting bracket to move. Thus, the support rod drives the chuck to move, and multiple chucks move outwards, so that the gradient block outside the chuck can be in close contact with the inner ring of the wheel hub, thereby achieving the purpose of quickly fixing the wheel hub. When disassembling the wheel hub, reverse the motor, and at this time, drive the chuck to move towards the center, and the quick disassembly of the wheel hub can be realized.
