In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1 to 2, the utility model discloses a motor stalling test frock, mounting panel 1 including the level is arranged, mounting panel 1's lower fixed surface has two at least supporting legs, be fixed with cylinder 2 on the mounting panel 1, cylinder 2's piston rod 3 runs through mounting panel 1 and stretches out in the installation below, piston rod 3's lower extreme has linked firmly upper junction plate 4, upper junction plate 4's lower surface can be dismantled and is fixed with upper die 5, upper die 5's lower surface is equipped with the spacing groove 6 of cambered surface form, the symmetry is equipped with lower moulding-die 7 under upper die 5, lower moulding-die 7 can be dismantled and be fixed in lower connecting plate 8's upper surface, lower fixed surface of lower connecting plate 8 has vertical telescopic machanism, vertical telescopic machanism adopts the telescopic link isotructure that mechanical field commonly used can.

When the tool is used, a motor to be tested is placed adjacent to the tool, a rotating shaft of the motor is horizontally arranged and located between an upper die and a lower die, the upper die 5 and the lower die 7 are selected according to the diameter of the rotating shaft, the diameter of the limiting groove 6 is equal to that of the rotating shaft, then the vertical telescopic mechanism is adjusted according to the height of the rotating shaft until the limiting groove 6 of the lower die 7 contacts the lower surface of the rotating shaft, and finally the air cylinder 2 is controlled to act, so that the upper die 5 moves downwards until the upper die 5 is pressed on the rotating shaft, and the rotating shaft is locked.

Furthermore, the supporting legs can be vertically telescopic, and the specific structure can be a telescopic structure commonly used in the field. Because the stroke of cylinder 2 is limited, if the supporting leg adopts conventional non-extending structure, then the pivot high scope of applicable is less, sets the supporting leg to scalable now, can improve the pivot height that this frock is suitable for greatly to also can reduce the demand to 2 strokes of cylinder.

The supporting leg comprises a bottom pipe 9 and a telescopic rod 10, the lower gap of the telescopic rod 10 is inserted into the bottom pipe 9, the upper end of the telescopic rod is fixedly connected with a mounting plate 1, two first through holes located at two ends of the same diameter are formed in the wall of the bottom pipe 9, multiple groups of second through holes uniformly distributed along the vertical direction are formed in the lower portion of the telescopic rod 10, each group of second through holes is formed by two second through holes located at two ends of the same diameter respectively, and the same bolt is inserted into the two first through holes and the one group of second through holes. During specific operation, the height of the mounting plate 1 is adjusted through movement of the telescopic rod 10 in the bottom pipe 9, when the mounting plate is adjusted to a proper position, the bolt penetrates through the two first through holes and one group of second through holes simultaneously, and the bolt is matched with the nut for locking.

Furthermore, the cross section of the bottom tube 9 is rectangular, and the cross section of the telescopic rod 10 is rectangular matched with the cross section of the bottom tube 9. The rectangular shape facilitates alignment of the first and second vias.

As an optimal structure of the vertical telescopic mechanism, the vertical telescopic mechanism is composed of at least two supporting columns 11, and the supporting columns 11 and the supporting legs adopt the same telescopic structure.

In order to further improve the friction force between the limiting groove 6 and the rotating shaft and ensure that the locking effect is firmer, a rubber pad is fixed in the limiting groove 6.

As a preferred structure of the upper/lower pressing die 7, the upper pressing die 5 and the lower pressing die 7 are both composed of a pressing die body 12 and a fixing plate 13, the fixing plate 13 and the connecting plate are both the same in shape and size and are connected through a bolt, and the limiting groove 6 is opened on the surface of the pressing die body 12. Convenient assembly and disassembly and firm connection.

Further, still include bottom plate 14, on the lower extreme of supporting leg and vertical telescopic machanism's lower extreme all was fixed in bottom plate 14, the lower surface mounting of bottom plate 14 had locking mechanism's universal wheel 15. On one hand, the stability of the whole device is improved, and the device can be effectively prevented from toppling; on the other hand, before experimental, this frock of easy horizontal migration of accessible universal wheel 15 for the pivot is arranged in between upper die 5 and the lower die 7, and is more convenient.
