Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a novel wheel hub reverse clamping tool. Background Art

[0002] At present, the wheel hubs of many automobile brands have the demand for undercut finishing. This kind of undercut finishing product needs to be clamped in reverse during processing. However, the commonly used second-stage support blocks are relatively small. When clamped from the front, they often come into contact with the high point of the spoke and cause pressure injuries. Products with large spoke angles are installed on the rib on one side and under the rib on the other side. Uneven positioning can lead to safety hazards such as collisions.

[0003] At present, the anti-stuck tooling at home and abroad mainly uses three-petal fan-shaped discs for processing. This three-petal fan-shaped disc has the following problems: (1) Each time the fan-shaped disc is replaced, it needs to be disassembled by a crane, which is difficult and takes up to 3 hours, and the operator has high labor intensity; (2) After each fan-shaped disc is replaced, it needs to be checked, and if it is unqualified, it takes about 1 hour to replace it with a new tool, and the processing accuracy is not high; (3) Since the fan-shaped disc is not often used, after the undercut is processed and fine-turned, the original tooling needs to be replaced, which takes about 3 hours.

[0004] In order to solve the above problems, it is necessary to design a new type of tooling to solve the problems of long replacement time of sector discs, high labor intensity and low processing accuracy. Utility Model Content

[0005] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the present invention proposes a new wheel hub anti-clamping tool, which includes a mounting plate, a mounting seat and a shaft rod, wherein the mounting seat and the mounting plate are fixedly connected by the shaft rod, one side of the mounting seat is fixedly connected to the motor seat, an adjustment structure is installed below the mounting plate, and a clamping structure is installed on the mounting plate;

[0006] The regulating structure includes a worm gear, a worm and a motor;

[0007] The shaft bearing is connected to the middle part of the worm wheel, the worm wheel is located below the mounting plate, the worm wheel and the opposite side of the mounting plate are in contact with each other, the worm wheel is provided with a group of evenly arranged arc-shaped grooves, the worm wheel is engaged with the worm, the motor is placed on one side of the motor base, the motor output end passes through the motor base and is fixedly connected to one end of the worm.

[0008] The present invention is further configured as follows: the clamping structure includes a set of cross slides, a set of clamping plates and a set of sliding columns;

[0009] The mounting plate is provided with a group of evenly arranged cross slides, a group of the cross sliders are slidably placed in the corresponding cross slides, a group of the cross sliders are fixedly connected to the corresponding splints on the upper sides, a group of the cross sliders are fixedly connected to the corresponding sliding columns on the lower ends, and a group of the sliding columns are slidably placed in the corresponding arc-shaped slides.

[0010] The present invention is further configured as follows: the outer ring of the mounting seat is provided with a group of evenly arranged mounting holes.

[0011] The utility model is further configured as follows: the outer sides of a group of the clamping plates are all coated with a hard rubber layer, which not only increases the friction between the clamping plates and the wheel hub, but also avoids indentations on the surface of the wheel hub.

[0012] The utility model is further configured as follows: the motor is a slow forward and reverse motor.

[0013] The beneficial technical effects of the present invention are as follows: when the present invention is in use, the device is installed on the machine tool through the mounting hole of the mounting seat, one side of the wheel hub is fitted against one side of the mounting disk, the motor is started, and under the action of the worm gear and the worm, a group of arc-shaped slide bars rotate, and a group of arc-shaped slide bars simultaneously drive the corresponding clamping plates to slide in the direction of approaching each other under the cooperation of the corresponding sliding columns and the cross sliders, and a group of clamping plates slide synchronously to clamp the outer side of the wheel hub, so that the clamped wheel hub is located in the middle of the mounting disk, and the wheel hub can be subsequently processed after clamping. The present device replaces the traditional fan-shaped disk structure, and is very convenient for clamping and loosening the wheel hub, as well as for installing and disassembling the device, thereby shortening the operation time and improving work efficiency.

[0018] Please refer to the attached Figure 1-Figure 3To describe the preferred embodiments of the present invention. It should be understood by those skilled in the art that these embodiments are only for illustration purposes.

[0019] The technical principle of the present invention is not intended to limit the protection scope of the present invention.

[0020] The utility model proposes a novel wheel hub anti-clamping tool. Before use, a group of splints 1 are at the farthest relative position, such as Figure 1 As shown, when using this device, according to needs, the device is installed at a suitable position of the machine tool through the mounting hole of the mounting seat 9 by means of bolts, one side of the wheel hub is fitted against one side of the mounting plate 3, the motor 6 is started, the motor 6 drives the worm 5 to rotate, the worm 5 drives the worm gear 4 engaged therewith to rotate, the worm gear 4 drives a group of arc-shaped slide grooves 7 to rotate in a circular trajectory, a group of arc-shaped slide grooves 7 drives the corresponding slide posts 8 to slide in the direction of approaching each other, a group of slide posts 8 drives the corresponding cross slide blocks 10 to slide along the corresponding cross slide grooves 3 in the direction of approaching each other, a group of cross slide blocks 10 drives the corresponding splints 1 to slide in the direction of approaching each other, when one After the opposite side of the group of plywood 1 is tightly fitted to the outer side of the wheel hub, the motor 6 is turned off. At this time, a group of plywood 1 fixes the wheel hub on the mounting plate 2. Since a group of plywood 1 slides synchronously, the wheel hub clamped by a group of plywood 1 is located in the middle of the mounting plate 2. After clamping the wheel hub, the wheel hub can be processed subsequently. After processing, the motor 6 is started again, and the motor 6 reverses to drive a group of plywood 1 to return to the initial position, release the fixation of the wheel hub, and remove the wheel hub. This device replaces the traditional fan-shaped disk structure, and is very convenient for clamping and loosening the wheel hub, as well as for installing and disassembling the device, which shortens the operation time and improves work efficiency.
