As be in crescent, formed with arc panel 801, existing fixture fails to fit like a glove the geometric form of brake shoe 8 periphery wall mostly
Shape, prevents shearing force from acting on completely in the section of shear of brake shoe 8 so that error occurs in result of the test.In order to solve
Clamping problem of the Motorcycle Brake Shoe on testing stand is, it is necessary to develop a kind of reliable shoe piece shearing test fixture.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of shearing test brake shoe fixture, by with system
Move the first stripping and slicing, the second stripping and slicing that hoof block shape is coincide and apply pressure, improve test accuracy.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of shearing test brake shoe fixture, includes base and is connected to the first line of a couplet moving up and down on base
Plate, the upper connective plate upper end are connected with for applying stressed pressure head, and the base upper surface is set respectively with upper connective plate bottom surface
There are the first stripping and slicing, the second stripping and slicing with brake shoe form fit, the first stripping and slicing side wall fits in the arc of brake shoe
Plate inner wall, second stripping and slicing are provided with the arc groove to match with the arc plate shape of brake shoe and are pressed in brake shoe
On the upside of arc panel, briquetting bearing and briquetting, the briquetting bearing is set to be provided with and the briquetting phase in first stripping and slicing
First stripping and slicing is bolted in the card slot of adaptation, the briquetting.
As the improvement of above-mentioned technical proposal, the slotted hole passed through for bolt is provided with the middle part of the briquetting.
Further as above-mentioned technical proposal is improved, and the base is provided with vertical optical axis, the upper connective plate installation
It can slide up and down on the optical axis and along optical axis.
Further, the optical axis is provided with two and splits the both sides of first stripping and slicing.
Further, the upper connective plate upper surface is provided with location hole, and the pressure head bottom surface is provided with and the location hole
The locating piece matched somebody with somebody.
Further, the pressure limit that the pressure head applies is 0 ~ 20MPa.
The beneficial effects of the invention are as follows：Brake shoe is pressed in the first stripping and slicing by briquetting, briquetting one end is stuck in branch
Positioned in the card slot of seat, the other end compresses brake shoe, applies pressure to upper connective plate by pressure head, pressure is cut by second
Block is applied on the arc panel of brake shoe, since the first stripping and slicing side wall fits in the inner wall of the arc panel of brake shoe, second
Stripping and slicing and arc plate shape match and are pressed on the upside of arc panel, are bonded the shape of brake shoe completely, shear transfer is steady,
Reliably, the accuracy of experiment is improved.Present invention practicality rational in infrastructure, implements simply, to help to improve test accuracy.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the decomposition texture schematic diagram of the present invention；
Fig. 2 is the use state diagram of the present invention；
Fig. 3 is the structure diagram of brake shoe.
Embodiment
With reference to Fig. 1 ~ Fig. 2, a kind of shearing test brake shoe fixture, including base 1 and be connected to can on base 1
