Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
A tool wheel drop test machine comprises a support 1, a rim frame 2, a rotating plate 3, a rotating roller 4, an adjusting round roller 5, an adjusting protrusion 6 and a rotating roller 7.
The rotating plate 3 is rotatably disposed on the bracket 1, one end of the rotating plate 3 is located below the rim frame 2, and the center of gravity of the rotating plate 3 is located at the other end, i.e., when no external force is applied to the rotating plate 3, the rotating plate 3 will rotate toward one end of the center of gravity, i.e., the left end shown in fig. 1 and 2. The roller 4 is rotatably arranged on the bracket 1, and the roller 4 is connected with a rotating mechanism, wherein the rotating mechanism can adopt a rotating motor.
The adjusting round roller 5 is arranged on the rotating roller 4; the adjusting protrusion 6 is arranged on the outer side of the adjusting circular roller 5, one side of the adjusting protrusion 6 is in an arc shape tangent to the adjusting circular roller 5, and the other side of the adjusting protrusion 6 is perpendicular to the adjusting circular roller 5. Referring to fig. 3 in conjunction, a rotating roller 7 is rotatably provided below the other end of the rotating plate 3, the rotating roller 7 corresponding to the regulating circular roller 5 and the regulating protrusion 6. The shape of the regulating circular roller 5 and the regulating protrusion 6 is similar to a cam. When the rotating roller 4 rotates, the adjusting round roller 5 and the adjusting protrusion 6 rotate along with the rotating roller, when the adjusting protrusion 6 is arranged, the rotating roller 7 can be lapped on the adjusting round roller 3 under the action of the adjusting round roller 5, but due to the existence of the adjusting protrusion 6, the rotating plate 3 can rotate along with the rotating roller, namely the rotating plate 3 can rotate clockwise when passing through the adjusting protrusion 6 in the direction shown in fig. 2; when rotor 7 on rotor plate 3 suddenly with adjust protruding 6 separation, then rotor plate 3 can be under the effect of no supporting force, anticlockwise rotation, the right-hand member of rotor plate 3 can strike the wheel that sets up on rim frame 2, the left end of rotor plate 3 has certain distance with regulation circle roller 5, in this time, even rotor plate 3 has the swing of certain degree, can not influence and make rotor plate 3 and regulation circle roller 5 contact yet, at this moment, the right-hand member of rotor plate 3 has certain reciprocal impact with the wheel, just in time reverse simulation wheel process of falling.
During the use, install the wheel on rim frame 2, then control changes roller 4 rotatory, adjusts the round roller 5 and adjusts protruding 6U rotation thereupon, and then drives rotor plate 3 swing, when swing board 3 with adjust protruding 6 from contacting the separation, rotor plate 3 can direct counter-clockwise turning because of the reason of gravity, the right-hand member top impact wheel of rotor plate 3, and then realize the drop test of wheel.
If only by the unbalanced gravity of the rotating plate 3, the falling test range can be smaller, so the weight adjusting block 8 is designed. The weight-adjusting block 8 is provided on the other end of the pivotal plate 3, i.e., the left end as viewed in fig. 2, to increase the speed at which the pivotal plate 3 rotates by increasing the weight force for adjusting the left side of the pivotal plate 3, thereby improving the strength of the impact wheel. As to the manner in which the weight adjusting block 8 is provided on the rotating plate 3, various solutions can be adopted. Firstly, as shown in fig. 4, a groove is arranged above the rotating plate 3, and a screw hole is arranged in the groove of the rotating plate 3; the weight adjusting block 8 is arranged in a groove of the rotating plate 3 in a sliding mode, and the weight adjusting block 8 is installed on the rotating plate 3 through screws. When the weight-adjusting block 8 is located at the leftmost side of the pivotal plate 3, the intensity of the impact of the pivotal plate 3 against the wheels is maximized, and when it is gradually moved to the right side, the impact intensity is decreased. Secondly, the outside of transferring heavy piece 8 is equipped with the slot, and the outside of rotor plate 3 is equipped with the slot, transfers heavy piece 8 and rotor plate 3 to link together through tying up the rope. The method is relatively original, but is also very practical.
Since the adjusting protrusion 6 contacts the rotating roller 7, a spacer 9 is provided outside the adjusting protrusion 6, and the spacer 9 can buffer hard friction between the adjusting protrusion 6 and the rotating roller 7, thereby improving the service life. The gasket 9 may be made of a conventional rubber material.
The fender is enclosed in the outside setting of support 1, improves the safety when detecting.
It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as there is no structural conflict; and all such modifications and alterations should fall within the scope of the appended claims.
