Description
Technical Field
The utility model relates to a drum brake shoe fixing device assembly and disassembly tools.
Background
At present, a drum brake is widely adopted in modern cars as a rear wheel brake device, and when braking, hydraulic pressure is applied to a brake cylinder to enable brake shoes to expand towards two sides and rub with a brake drum to form braking force to block the rotation of wheels. When the driving mileage of the vehicle increases, the brake shoes are worn and need to be replaced. Adopt traditional pliers class instrument to dismantle brake shoe fixing device (spring shim), easily lead to the gasket to pop out, have the potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model provides a drum brake shoe fixing device assembly and disassembly tools can effectively solve above-mentioned problem.
The utility model discloses a realize like this:
a drum brake shoe fixing device dismounting tool comprises a sleeve and an operating handle connected with one end of the sleeve; the sleeve further comprises a first connecting portion connected with the operating handle, a magnetic ring and a second connecting portion connected between the first connecting portion and the magnetic ring, the diameter of an inner cavity of the magnetic ring is gradually reduced along the extending direction from the sleeve to the operating handle, and the inner cavity of the magnetic ring is provided with a chamfer vertical groove matched with the drum brake shoe.
As a further improvement, the sleeve and the operating handle are connected by a screw thread.
As the further improvement, the second connecting part is of an annular arc sheet structure and is hollow inside.
As a further improvement, an included angle of 40-50 degrees is formed between the chamfer vertical groove and the extending direction from the sleeve to the operating handle.
The utility model has the advantages that: the utility model discloses simple structure, the sleeve and operating handle passes through threaded connection, and the not unidimensional sleeve of ability quick replacement adapts to the dismantlement of different model brake shoes, has reduced dismouting personnel's intensity of labour.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1, the dismounting tool for the shoe fixing device of the drum brake comprises a sleeve 2 and an operating handle 1 connected with one end of the sleeve 2; the sleeve 2 further comprises a first connecting portion 20 connected with the operating handle 1, a magnetic ring 22 and a second connecting portion 21 connected between the first connecting portion 20 and the magnetic ring 22, the diameter of an inner cavity of the magnetic ring 22 decreases progressively along the extending direction of the sleeve 2 to the operating handle 1, and the inner cavity of the magnetic ring 22 is provided with a chamfered vertical groove 220 matched with the drum brake shoe.
As a further improvement, the sleeve 2 and the operating handle 1 are connected by a screw thread.
As a further improvement, the second connecting portion 21 has an annular arc structure and is hollow inside.
As a further improvement, an included angle of 40-50 degrees is formed between the chamfer vertical groove 220 and the extending direction of the sleeve 2 to the operating handle 1.
Preferably, the chamfer vertical groove 220 forms a 45-degree included angle with the extending direction of the sleeve 2 to the operating handle 1.
The utility model relates to a drum brake shoe fixing device assembly and disassembly tools's actual dismantlement process as follows:
firstly, selecting a proper sleeve 2 according to requirements, wherein the sleeve 2 is in threaded connection with the operating handle 1, when the brake shoe is disassembled, a gasket and a spring are pressed forcibly, and then the spring is rotated by 90 degrees, so that a cutting groove in the center of the spring gasket is matched with the port of a spring supporting pin, the gasket is taken out smoothly, the magnetic ring 22 sucks the gasket, the brake shoe is in a loose state, and the disassembly of the brake shoe is completed; during the installation, will earlier spring shim center grooving with the spring support pin port corresponds, the reuse the utility model discloses the spring shim is pressed to the instrument, until exposing the pin port, rotates 90 degrees again, makes the gasket is fixed on the pin, has fixed simultaneously the brake shoe is accomplished the installation of brake shoe.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
