Description

Technical Field

[0001] The utility model relates to the technical field of brake drum processing, and particularly relates to a special lifting tool for brake drum processing. Background Technique

[0002] The brake drum is a friction pair of a drum brake. In addition to having the strength and stiffness required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity, etc.

[0003] At present, most of the lifting tools for brake drums are made of a suspension rod, a hanging ear and a hinge seat to form a brake drum lifting tool. Although this method can lift brake drums of different sizes, the diameters of the hinge seat and the hanging ear itself are relatively thin, and the quality of the brake drum itself is relatively heavy. After long-term use, the hooks and blocks are prone to looseness. If not discovered in time, there are likely to be safety hazards after lifting. Content of the Utility Model

[0004] To solve the above problems, that is, to solve the problems proposed in the above background technique, the utility model provides a special lifting tool for brake drum processing, which includes an upper arc-shaped plate, a lifting ring, a connecting plate and an arc-shaped supporting plate. One end of the arc-shaped supporting plate is fixedly connected to an arc-shaped baffle, and one side of the arc-shaped baffle and the upper arc-shaped plate are fixedly connected through the connecting plate. The upper side of the upper arc-shaped plate is a plane, and the lifting ring is arranged on the upper plane of the upper arc-shaped plate. A straight groove plate one is fixedly connected to the lower side of the arc-shaped supporting plate. A height adjustment structure is installed in the straight groove plate one, and a center hole fixing structure is installed on the straight groove plate one.

[0005] The height adjustment structure includes a lead screw one, a slider one, a motor one and a straight groove plate two;

[0006] Both ends of the straight groove plate one are respectively connected to one end of the lead screw one through bearings. The motor one is arranged at the lower end of the straight groove plate one. The output end of the motor one passes through the straight groove plate one and is fixedly connected to the lower end of the lead screw one. The slider one is slidably arranged in the straight groove plate one. The lead screw one is threadedly connected to the slider one. One side of the slider one is fixedly connected to the straight groove plate two.

[0007] A further setting of the utility model is that the center hole fixing structure includes a lead screw two, a pair of sliders two, a motor two, a pair of support rods and two groups of arc-shaped clamping plates;

[0008] Both ends of the second straight groove plate are respectively connected to one end of the second lead screw through bearings. The second lead screw is provided with two threads with opposite helix directions. The second motor is arranged at one end of the second straight groove plate. The output end of the second motor passes through the second straight groove plate and is fixedly connected to one end of the second lead screw. A pair of the second sliders are slidably arranged on the second straight groove plate. Both ends of the second lead screw are respectively threadedly connected to the corresponding second sliders. One side of each pair of the second sliders is respectively fixedly connected to the corresponding support rod. One side of each pair of support rods is respectively fixedly connected to a corresponding set of arc-shaped clamping plates. The pair of arc-shaped clamping plates are located at the position with the farthest relative distance.

[0009] A further setting of the present utility model is that: one set of the arc-shaped clamping plates all extend beyond the other end of the arc-shaped supporting plate.

[0010] A further setting of the present utility model is that: the surfaces of the arc-shaped supporting plate and the two sets of arc-shaped clamping plates are all coated with a soft rubber layer to prevent scratching their surfaces when fixing the brake drum.

[0011] A further setting of the present utility model is that: the cross sections of the two sets of arc-shaped clamping plates are both U-shaped surfaces.

[0012] A further setting of the present utility model is that: the distance between each set of arc-shaped clamping plates does not exceed 5 mm.

[0013] A further setting of the present utility model is that: both the first motor and the second motor are slow-speed forward and reverse motors.

[0014] A further setting of the present utility model is that: the diameter range of the central holes that the two sets of arc-shaped clamping plates can be clamped is 50 - 90 mm.

[0015] A further setting of the present utility model is that: the width of the arc-shaped supporting plate > 60 mm.

[0016] A further setting of the present utility model is that: the distance between the arc-shaped supporting plate and the arc-shaped top plate is greater than 200 mm, which is convenient for processing the upper surface of the brake drum rim.

[0017] The beneficial technical effect of the present utility model is that: first, place the rim of the brake drum on the arc-shaped supporting plate, then adjust the positions of the two sets of arc-shaped clamping plates according to the model of the brake drum. After moving the arc-shaped clamping plates to the diameter position of the central hole of the rim, slightly move the brake drum to align the rim of the brake drum with the pair of arc-shaped clamping plates. Fix the central hole of the brake drum rim through the pair of arc-shaped clamping plates, fix the brake drum through the cooperation of the arc-shaped supporting plate and the pair of arc-shaped clamping plates, lift the device through the lifting ring, and then perform subsequent processing on the brake drum. It replaces the traditional combination of the suspension rod, suspension ear and hinge seat. Most of the force brought by the brake drum is removed through the arc-shaped clamping plates, reducing the force on the arc-shaped clamping plates and increasing the service life of the device.

Specific embodiments

[0022] The following will describe the preferred embodiments of the present utility model with reference to the attached Figures 1-3 Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0023] The present utility model provides a special lifting tool for brake drum processing. Before use, a pair of sliders 2 are in the position with the closest relative distance, and two groups of arc clamping plates 8 are in the position with the closest relative distance. When using this device, place the drum ring of the brake drum body 12 to be lifted on the arc supporting plate 3, pass the two groups of arc clamping plates 8 through the central hole of the brake drum body 12, and make the inner side of the drum disc of the brake drum body 12 fit the side of the arc supporting plate 3. Start the motor 1, the motor 1 drives the lead screw 1 to rotate, the lead screw 1 drives the slider 14 to slide, the slider 14 drives the straight groove plate 9 to slide, and the straight groove plate 9 drives the two groups of arc clamping plates 8 to slide to the diameter of the central hole of the drum disc of the brake drum body 12, then turn off the motor 1 (when the motor 1 rotates forward, the straight groove plate 9 slides upward, conversely, when the motor 1 rotates, the straight groove plate 9 slides downward, and it can be adjusted according to the position of the central hole of the hub). Observe from the side whether the U-shaped grooves of the two groups of arc clamping plates 8 are aligned with the drum ring of the brake drum body 12. If there is a deviation, slightly move the brake drum body 12 outward (since the distance between each group of arc clamping plates 8 is relatively close, only slightly move the brake drum body 12 to avoid excessive movement distance and the arc supporting plate 3 cannot bear most of the weight of the brake drum body 12), and align a pair of arc clamping plates 8 with the drum disc of the brake drum body 12. As Figure 2 shown, start the motor 2, the motor 2 drives the lead screw 2 to rotate, and the lead screw 2 drives a pair of arc clamping plates 8 to slide in the direction away from each other. When the U-shaped grooves of a pair of arc clamping plates 8 are tightly attached to the inner ring of the drum disc, turn off the motor 2, and fix the brake drum body 12 through the cooperation of the arc supporting plate 3 and a pair of arc clamping plates 8. AsFigure 3 As shown in the figure, the device is lifted by the lifting ring 1, and subsequent processing of the brake drum body 12 can be carried out, replacing the combination of the traditional suspension rod, hanger ear and hinge seat. Most of the force brought by the brake drum body 12 is removed by the arc-shaped clamping plate 3, reducing the force on the arc-shaped clamping plate 8, increasing the service life of the device, and increasing the safety of the device, which is convenient for fixing and lifting brake drum bodies 12 of different models.
