DETAILED DESCRIPTION

[0019] Reference Figs. 1 to 3The utility model provides a heavy truck brake caliper body immersion type electrophoretic coating lifting appliance, which comprises a top lifting trolley 1 and a plurality of groups of lifting appliance racks 2 installed on the top lifting trolley.

[0020] The lifting appliance rack 2 comprises a lifting appliance frame 21 and double hooks 22 arranged at the top center of the lifting appliance frame and welded by a welding process.

[0021] The lifting appliance frame 21 comprises a middle vertical rod 211 arranged vertically and inverted triangular structures 212 welded on the middle vertical rod from top to bottom; the unique structural layout can reduce the weight of the frame while ensuring the strength and rigidity required to bear the weight of multiple brake caliper bodies, facilitating hoisting. The design of the inverted triangular structure can uniformly disperse the stress and enhance the overall stability. The lifting appliance frame 21 is the basic support structure of the entire lifting appliance and also part of the conductive path, and the selected high-strength steel has good conductivity.

[0022] The double hooks are arranged in a bent manner and hung on both sides of the top lifting trolley, are made of steel bars, have high strength and reliability after special process treatment, are used for connecting with the trolley to realize the hoisting of the lifting appliance and the brake caliper body. The double hooks also have a conductive function and can introduce current into the lifting appliance frame when connected with the trolley;

[0023] In order to facilitate the hoisting of the heavy truck brake caliper body, a lifting hook structure 221 is arranged on both sides of the inverted triangular structure 22, and each lifting hook structure corresponds to the installation of one heavy truck brake caliper body. The lifting hook structure is made of high-strength alloy steel and has good toughness and strength. The shape is specially designed according to the suspension part of the brake caliper body to ensure the stability of the brake caliper body during suspension. The hook not only firmly suspends the brake caliper body but also serves as a key link for conduction, transferring the current conducted by the lifting appliance frame to the brake caliper body;

[0024] In order to facilitate the cooperation with the lifting appliance frame 2 installation, the top hoisting crane 1 is provided with a plurality of groups of matching double hooks used with the hanging rod 11, and the adjusting assembly 3 used with the lifting appliance frame 2 is arranged beside the hanging rod. The adjusting assembly 3 comprises a threaded hole opened on the top hoisting crane 1, an adjusting bolt 31 threaded in the threaded hole, and a hexagonal nut 32 matched with the adjusting bolt 31. By rotating the adjusting bolt, the position of the hook can be adjusted and fixed to prevent the brake caliper body from shaking during the electrophoresis process to adapt to the possible movement. The adjusting bolt ensures the stability of the hook while ensuring the stable connection of the conductive path. Specifically, when the lifting appliance frame 2 is hung on the hanging rod 11, and the adjusting assembly 3 is installed as needed, the double hooks 22 of the lifting appliance frame 2 are in close contact with the adjusting nut 31, and the hexagonal nut 32 is in close contact with the double hooks 22. Since the hexagonal nut 32 is threaded in the adjusting bolt 31, the hexagonal nut 32 will rotate when the adjusting bolt 31 is rotated, so that the part in contact with the double hooks 22 will change from the sharp corner of the hexagonal nut to the flat part, and the small angle adjustment of the entire lifting appliance frame 2 will be realized in turn. In addition, since the lifting appliance frame 2 is hung on the hanging rod 11, the angle of rotation can be adjusted by adjusting the position of the entire adjusting assembly 3, so that the lifting appliance frame 2 relies on the angle change of the adjusting assembly 3 to realize large-angle adjustment. At the same time, the adjusting bolt 31 will be in contact with the double hooks 22 after being tightened, thereby realizing the fastening effect.

[0025] The working process of the embodiment is as follows:

[0026] Preparation stage: According to the size and shape of the brake caliper body, rotate the adjusting bolt to adjust the position and angle of the hook, so that the hook is accurately matched with the suspension part of the brake caliper body. Ensure that the brake caliper body can be stably suspended on the hook, and ensure that the hook and the brake caliper body have good conductive contact;

[0027] Suspension workpiece stage: The brake caliper body 4 is suspended on the lifting hook structure 23 on both sides of the inverted triangular structure. Due to the special design of the hook, it can closely fit the suspension part of the brake caliper body, realize firm suspension and good conductive connection, and in fact the brake caliper body hook can be installed on the lifting hook structure 23, and they will be in close contact at the same time. At this time, the current can be conducted from the frame to the brake caliper body through the hook;

[0028] Hoisting stage: use the crane to connect with the double hooks on the top of the lifting appliance frame, lift the entire lifting appliance together with the brake caliper body stably, and hoist it to the top of the electrophoresis tank. Then slowly lower it to immerse the brake caliper body in the electrophoretic solution. In this process, the crane is connected with the double hooks, the current is introduced from the crane to the frame through the double hooks, and then conducted to the brake caliper body through the lifting assembly;

[0029] The electrophoresis stage: the power supply of the electrophoresis equipment is turned on, and the current is conducted to the brake caliper body through the hooks of the crane, double hooks, frame and hanger assembly. Under the action of the electric field, the paint particles in the electrophoretic fluid move to the surface of the brake caliper body and deposit to form a coating. During the electrophoresis process, the brake caliper body may move slightly due to the flow of the electrophoretic fluid and other factors. At this time, the hooks are firmly fixed on the frame by the adjusting bolts to prevent the brake caliper body from shaking, ensure the stability of the conductive path, and ensure the relative stability of the position of the brake caliper body and the stability of the current conduction during the electrophoresis process, thereby ensuring the uniformity of the coating quality.

[0030] The hoisting-out stage: after the electrophoretic coating is completed, the crane hoists the hanger and the brake caliper body out of the electrophoresis tank through the double hooks again, and drains the excess electrophoretic fluid on the surface. Then it is hoisted to the designated position, the brake caliper body is removed, and the electrophoretic coating operation is completed. At this time, the power supply is cut off, and the current conduction stops.

[0031] The utility model discloses the beneficial aspect, the hanger frame of this technical scheme adopts the design of inverted triangular structure and the connection of middle horizontal pole, guarantees the hanger carrying capacity and lightens the dead weight, and the frame is as part of the conductive path, and this structure and the integrated design of conductive function meet the mechanical property requirement, simplify the layout of the conductive system, improve the overall reliability and efficiency.

[0032] In addition, a plurality of inverted triangular structures are arranged on the same group, and one hanger can simultaneously suspend at least four brake caliper bodies for electrophoretic coating. Compared with the traditional hanger that can only process one or a few workpieces at a time, the number of hoisting and electrophoresis operations is greatly reduced, the overall production cycle is significantly shortened, and the production output per unit time is improved.

[0033] The whole hanger has good conductive performance, and a stable conductive path is formed from the crane through the double hooks, the hanger frame and the brake caliper body. Stable current conduction ensures uniform electric field distribution during the electrophoresis process, so that the paint particles can uniformly deposit on the surface of the brake caliper body, improve the quality and consistency of the coating, and reduce coating defects caused by unstable current, such as pitting and pinholes.

[0034] The adjusting assembly can not only fix the position of the hook, but also adapt to the slight movement of the brake caliper body during the electrophoresis process. Under the action of the flow of the electrophoretic fluid and the electric field, the brake caliper body may have slight displacement, and the cooperation of the adjusting bolt and the hook can ensure that the brake caliper body still maintains a stable suspension and conductive state under this condition, and ensure the smooth progress of the electrophoretic coating process.

[0035] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
