Description

Technical Field

[0001] The present application relates to the technical field of brake pad production, and in particular to a drum brake pad turning mechanism. Background Art

[0002] The grinding of the inner arc surface of automobile drum brake pads is a relatively tedious processing procedure in the production of automobile parts. The main reason is that the inner arc surface is concave inward, which is difficult to process. If you are not careful, it will directly affect the processing accuracy. Generally, the inner arc surface of the drum brake pad is processed first, and then the outer arc surface of the drum brake pad is ground. The main function of the brake pad flipping mechanism is to flip the drum brake pads in non-standard positions to the state where the inner arc surface faces down.

[0003] After searching, the Chinese patent with application number: 202220221810.X discloses an automatic flipping device for drum brake pads, including a rotating clamp fixing frame, on which a clamping assembly is arranged, the clamping assembly includes a static rod and a moving rod, the static rod is fixed on a static rod mounting plate, the moving rod is located below the static rod and fixed on the moving rod mounting plate, a telescopic assembly is arranged between the moving rod mounting plate and the static rod mounting plate, and the telescopic assembly drives the moving rod mounting plate to approach or move away from the static rod mounting plate.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] Common brake pad flipping mechanisms mainly clamp the drum brake pads through a moving rod and a stationary rod. In order to remove the drum brake pads from between the moving rod and the stationary rod so as to process their outer arc surfaces, specially designed clamps are required to remove the drum brake pads. The overall structure is relatively complex and the production cost is high, which is not conducive to market promotion and application. Utility Model Content

[0029] The beneficial technical effects of the drum brake pad turning mechanism of the embodiment of the present application are roughly as follows:

[0030] The supporting member 3 in the initial state of rotation is arranged tilted relative to the horizontal seat 1, and the drum brake pad can be dropped onto the concave supporting surface of the supporting member 3 by manual placement or automatic conveyance by a conveyor belt. At this time, the drum brake pad is in a tilted state. Starting the flipping drive group 4 can drive the supporting member 3 to rotate until the supporting member 3 rotates to the end state of rotation. At this time, the drum brake pad is in a horizontal state with the outer arc surface facing upward. The structure of the entire flipping mechanism is relatively simple, and there is no need to specially design a clamp to remove the drum brake pad subsequently. The production cost is low, which is conducive to market promotion and application.

[0031] In this embodiment, the bearing member 3 includes a rotating shaft 31, a connecting block 32 and a supporting arc plate 33. The rotating shaft 31 passes through and is rotatably assembled on the top of the column 2. The connecting block 32 is fixed to one end of the rotating shaft 31. The connecting block 32 is fixed to the bottom of the supporting arc plate 33. The concave supporting surface is the upper surface of the supporting arc plate 33. The top of the column 2 is provided with a rotating seat 21, and a bearing 22 is provided between the rotating shaft 31 and the rotating seat 21. The material of the supporting arc plate 33 can be a stainless steel plate, and a layer of a rubber soft plate with large friction can be pasted on the upper surface of the stainless steel plate to form a concave supporting surface, so as to achieve a good anti-slip effect, and the drum brake pad is not easy to fall off during the rotation process.

[0032] The bearing member 3 designed as above has a simple structure, a relatively low manufacturing cost, and a very stable rotation process, which is conducive to the drum brake pad being efficiently and safely turned over to a desired state.

[0033] In this embodiment, the flip driving group 4 includes a telescopic power member 41 and a transmission arc rod 42, the top end of the transmission arc rod 42 is fixed to the other end of the rotating shaft 31, the main end of the telescopic power member 41 is hinged to the other end of the horizontal seat 1, and the bottom end of the transmission arc rod 42 is hinged to the telescopic end of the telescopic power member 41, wherein a hinge pin 43 is arranged between the transmission arc rod 42 and the telescopic end of the telescopic power member 41, and a fixed block 11 is arranged on the other end of the horizontal seat 1, and the main end of the telescopic power member 41 is hinged to the fixed block 11.

[0034] Specifically, the telescopic power member 41 is a cylinder, and in other embodiments, the cylinder can also be replaced by an oil cylinder or an electric push rod.

[0035] The above-designed flip driving group 4 has a simple structure and stable operation, and can drive the supporting member 3 to rotate efficiently and safely.

[0036] In order to facilitate the firm connection between the column 2 and the horizontal seat 1, an inverted T-shaped end 23 is provided at the bottom of the column 2, and the inverted T-shaped end 23 is fixed to the horizontal seat 1 by multiple groups of bolts.
