Embodiment
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skills are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection scope of the present invention.
As shown in Figure 1 and Figure 2, the schematic perspective view that Fig. 1 is push-pull effort test fixture 100 in present embodiment, the front view that Fig. 2 is push-pull effort test fixture 100 shown in Fig. 1.Above-mentioned push-pull effort test fixture 100 comprises installing plate 10, and be arranged at installing plate 10 tops and base plate 11 in parallel, also be provided with bracing frame 12 above base plate 11, this bracing frame 12 comprises that fixed head 121, self-retaining plate 121 1 ends extend and the vertical portion 122 vertical with fixed head 121, and from vertical portion 122 other ends extend and with vertical portion 122 rake 123 at an angle.Fixed head 121 is parallel to installing plate 10 and base plate 11.
Above-mentioned push-pull effort measured material 100 also comprises test board 13, and test board 13 provides the measurement operating platform for part to be measured (as the needle roller rotating shaft retainer in automotive field).This test board 13 is arranged at the top of rake 123, and both are parallel to each other by relative wall.Further, the inner cavitys 130 that form of test board 13, cavity 130 be shaped as a round platform, therefore, cavity 130 has a sidewall 1301 and a roof 1302, sidewall 1301 and roof 1302 form madial wall 1301 and the inner roof wall 1302 of test board 13 simultaneously.
The push-pull effort measured material 100 so arranged, the sidewall 1301 at the most close above-mentioned fixed head of cavity 130 121 places parallels with fixed head 121.
Cooperation is with reference to shown in Fig. 3, Fig. 4, the rear view that Fig. 3 is bracing frame 12 in Fig. 1, Fig. 4 is the schematic diagram for the pressure test of test part performance parameter 200, and for the inner structure of better performance pressure test 200, its underpart utilizes partial sectional view to be meaned.Be provided with the some balls 131 for push-pull effort test on the sidewall 1301 of above-mentioned cavity 130, this ball 131 can match with the shape of part to be measured and pressure test 200.Because the sidewall 1301 at the most close fixed head 121 places parallels with fixed head 121, therefore, when carrying out the push-pull effort test, pressure test 200 can contact with the part to be measured on being positioned over ball 131 with the direction perpendicular to fixed head 121, such way of contact, between part to be measured and pressure test 200 stressed evenly, the performance parameter of the part of acquisition is accurately stable.
Further, above-mentioned test board 13 is to be connected with the rake 123 of bracing frame 12 by a rotating driving device 14.This rotating driving device 14 can drive test board 13 to rotate in the plane at the wall relative with rake 123.Particularly, be provided with a host cavity 1231 on rake 123, rotating driving device 14 is contained in above-mentioned host cavity 1231.Rotating driving device 14 comprises: whirligig (being positioned at host cavity 1231 inside, therefore not shown), rotating shaft 142, handle 143, and ring flange 144.Wherein, ring flange 144 is fixed on the sidewall with the rake 123 of test board 13 opposite sides by the mode of being spirally connected, and then whirligig, rotating shaft 142, handle 143 are fixed in the host cavity 1231 of rake 123 by above-mentioned ring flange 144.Rotating driving device 14 with the annexation of test board 13 is: offer a through hole 132 on the roof of test board 13, above-mentioned rotating shaft 142 is fixedly connected with rotating driving device 14 by through hole 132 with test board 13.
Also offer the some hole 1301a that accommodate ball 131 on the sidewall 1301 of cavity 130, the quantity of hole 1301a is all corresponding with ball 131 with shape.For ball 131 can better be matched with part to be measured, hole 1301a is evenly distributed on sidewall 1301 ringwise.Preferably, the quantity of hole 1301a is 15.
Utilize 100 pairs of parts to be measured of above-mentioned push-pull effort measured material to be fixed while measuring, at first part to be measured is positioned on the sidewall 1301 of cavity 130, and work good with ball 131, now, the sidewall 1301 that approaches most place with fixed head 121 is parallel with fixed head 121, thereby, be positioned at the part to be measured that approaches fixed head 121 places most also parallel with fixed head 121.Therefore, pressure test 200 can contact with part to be measured along the direction perpendicular to fixed head 121.During measurement, one end of pressure test 200 has the test chamber 20 matched with ball 131 shapes, when pressure test 200 moves down, test chamber 20 is with after ball 131 matches, surveying instrument (not shown) gathers measured push-pull effort test data, after collection, in pressure test 200, move, thereby complete once the local test of part to be measured.Then, tester's swing handle 143, because the quantity of the hole 1301a that accommodates ball 131 is 15, therefore make test board 13 rotate 24 °.Make next ball 131 move to the position of the most close fixed head 121, repeat above-mentioned measurement operation.Like this, in the time of just can guaranteeing to measure, pressure test 200 keeps vertical the contact with parts to be measured all at every turn, and such way of contact pressure distribution is even, and the measurement data of acquisition is stablized accurate.
Above-mentioned fixed head 121, base plate 11, and installing plate 10 on be respectively arranged with the first groove 1211, the second groove 111, and the 3rd groove 101, fixed head 121, base plate 11, and installing plate 10 can along the first groove 1211, the second groove 111, and the 3rd groove 101 do relative motion.
The second groove 111, the 3rd groove 101 be arranged in parallel, the first groove 1211 and the second groove 111, and vertical setting of threeway 101 grooves.Like this, the central point of establishing installing plate 10 is initial point, can realize the movement of test board 13 in directions X and Y-direction by movable base plate 11 and fixed head 121, thereby be convenient to the tester, adjusts test board 13 to suitable position, facilitates carrying out of test job.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limit related claim.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, and the technical scheme in each embodiment also can, through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
