For can concise description for the purpose of problem, below to a kind of brake shoe shearing test machine of the present invention all referred to as this testing machine.
Adopt this testing machine, brake shoe is positioned on fixture, allow motor operation, by the output shaft of reductor, the brake shoe that allow fixture, is arranged on fixture rotates, by fixture and the cooperation of tearing head, can be easily and quickly to the brake shoe tear test that stretches, compare with classic method, both saved the time, reduced again workman's labor capacity.
Described fixture comprises and mutually reclining and coaxial two ring blocks that are installed on output shaft, there is one to settle annular groove between two ring blocks, the outer circumference of each ring block is to uniform some positioning jacks with settling annular groove to communicate and parallel with output shaft, and the quantity of the positioning jack on two ring blocks is identical and their are corresponding one by one in position respectively;
Described tear the head be a vertical plate body, the top of plate body is pointed, there is an arcwall face that matches with two ring blocks on the top of plate body near a side of two ring blocks, one recessed to the arc of downward-extension corresponding to settling the annular groove place to have on arcwall face, the dip plane with respect to arcwall face is arranged at the top of plate body.
After adopting above structure, for having at least fixture cooperatively interacting and this testing machine of tearing head, its concrete use procedure is described as follows: allow the gusset of brake shoe put in the arrangement annular groove, and insert register pin in the corresponding mounting hole of the corresponding positioning jack in every two positions and gusset on two ring blocks, the arc-shaped curved surface plate of brake shoe is being walked upwards consistent (all being circumferencial direction) substantially with the face of cylinder of two ring blocks, at this moment, just the brake shoe clamping is located; Allow motor operation, output shaft by reductor, the brake shoe that allow fixture, is arranged on fixture rotates, make the arc-shaped curved surface plate of brake shoe contact with the dip plane of tearing a top, make simultaneously the gusset of brake shoe enter the arc of tearing a top recessed in, like this, by fixture and the cooperation of tearing head, can be easily and quickly to the brake shoe tear test that stretches.Separately, the fixture of said structure form and tear head makes the simple and reasonable of this testing machine.
As optimization of the present invention, described reductor adopts double-stage horizontal cycloidal pin reductor, described reductor has two horizontal output shafts that are arranged symmetrically with, and arranges all on each output shaft of described reductor that some versions are identical, specification is different and the fixture of space;
Be equipped with corresponding to each fixture place the head of tearing that coordinates with corresponding fixture on base plate.
The fixture that described specification is different refers to: the diameter of ring block and the aperture of positioning jack, quantity, circumferential arrangement position are different.
After adopting above structure, be applicable to stretch and tear the brake shoe of a plurality of specifications, two output shafts stressed evenly.On each fixture, the brake shoe of a dimension can be installed, like this, can be simultaneously to the tear test that stretches of the brake shoe of a plurality of specifications, further saved the time, reduced again workman's labor capacity, increase substantially test efficiency.
Description of drawings
Fig. 1 is the front view of this testing machine;
Fig. 2 is the left view of this testing machine;
Fig. 3 is the partial enlarged drawing of M section in Fig. 2.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1 to Fig. 3, the end cap 33 that will be arranged on output shaft 31 outer ends in Fig. 1 is left out.This testing machine comprises horizonal base plate 1, be fixed with on base plate 1 motor 2, with the coaxial reductor that joins 3 of motor 2.Motor 2 adopts 3kw, 8 grades of motors, and rotating speed is low, moment of torsion is large.Reductor 3 adopts double-stage horizontal cycloidal pin reductor, and reductor 3 has two horizontal output shafts that are arranged symmetrically with 31.
All arrange two on each output shaft 31 of reductor 3 version is identical, specification is different and the fixture 4 by spacer 32 spaces; On each output shaft 31, outermost that fixture 4 blocks by the end cap 33 that is arranged on this output shaft 31 outer ends.Fixture 4 is used for installing brake shoe, and brake shoe is made of arc-shaped curved surface plate A, the gusset B that is welded on curved slab A medial surface, the upper uniform some mounting hole C of gusset B.Fixture 4 comprises and mutually reclining and by coaxial two ring blocks 41 that are installed on output shaft 31 of square button, there is one to settle annular groove 42 between two ring blocks 41, the quantity of the positioning jack 43 of the outer circumference of each ring block 41 on uniform some 43, two ring blocks 41 of positioning jack with settling annular groove 42 to communicate and paralleling with output shaft 31 is identical and their are corresponding one by one in position respectively.The fixture 4 that specification is different refers to: the aperture of the diameter of ring block 41 and positioning jack 43, quantity, circumferential arrangement position are different.
On base plate 1 corresponding to each fixture 4 places be equipped with coordinate with corresponding fixture 4 tear 6, match with two fixtures 4 on each output shaft 31 two tear 6 and share bases 5, tear 6 and join with base plate 1 by the base 5 that shares for described two.Each tear 6 with respective seat 5 between coordinate with square button 51, and each tear 6 and respective seat 5 between be screwed, like this, comparatively stable when brake shoe is stretched tear test.For the purpose of clearly demonstrating problem, in Fig. 2, two of left side are torn head and base that both share and leave out.Tearing 6 is a vertical plate body, the top of plate body is pointed, there is an arcwall face 61 that matches with two ring blocks 41 on the top of plate body near a side of two ring blocks 41, one recessed 62 to the arc of downward-extension corresponding to settling annular groove 42 places to have on arcwall face 61, the dip plane 63 with respect to arcwall face 61 is arranged at the top of plate body.Tear a upper end of 6 concordant with the center line of the ring block 41 of corresponding fixture 4.
the below tears 6 as example take fixture 4 cooperatively interacting and one, concrete use procedure to this testing machine describes: allow the gusset B of brake shoe put in arrangement annular groove 42, and insert register pin D in the corresponding mounting hole C of the corresponding positioning jack 43 in every two positions and gusset B on two ring blocks 41, the arc-shaped curved surface plate A of brake shoe is walking upwards consistent (all being circumferencial direction) substantially with the face of cylinder of two ring blocks 41, at this moment, just the brake shoe clamping is located, (rotating speed of motor 2 is 10 rev/mins of left and right by motor 2 work with a flowing mode, security with warranty test), output shaft 31 by reductor 3, allow fixture 4, the brake shoe that is arranged on fixture 4 rotates, the arc-shaped curved surface plate A that makes brake shoe with tear a dip plane on 6 tops 63 and contact, making simultaneously the gusset B of brake shoe enter tears in an arc on 6 tops recessed 62, like this, by fixture 4 with tear a cooperation of 6, can facilitate, rapidly to the brake shoe tear test that stretches, compare with classic method, both saved the time, reduced again workman's labor capacity.
Adopt this testing machine, be applicable to stretch and tear the brake shoe of four specifications, two output shafts 31 stressed evenly.The brake shoe of a dimension can be installed on each fixture 4, like this, can be simultaneously to the tear test that stretches of the brake shoe of four specifications, further saved the time, reduced again workman's labor capacity, increase substantially test efficiency.
