Abstract
The utility model relates to a combination type spanner for withdrawing sleeves of bearing, which is a mechanical maintenance tool that can withdraw elements fixedly sheathed in an axis. Existing products are divided into two types, a two-jaw type and a three-jaw type. The utility model combines both the two types into a whole, and namely, included angles among three pull rod ends are mutual 120 DEG, a bisected angle position between two ends among the three is connected with a fourth pull rod end, which causes the spanner to be used with both two-jaw and three-jaw according to actual needs.
Description
The utility model is a kind of mechanical maintenance tool in use, and particularly the dismounting parts of adapter sleeve on axle draws the horse card.
In the flight-line maintenance industry,,, adopt usually and draw horse such as bearing in order to dismantle the parts of adapter sleeve on axle.And, need use three-jaw sometimes according to by the limitation of inloading part position in machine, and need use two pawls sometimes, therefore must respectively be equipped with a cover, and on the existing market this two series products only be arranged also.Three drag link ends of Three-claw pull-horse card are 120 ° of angles each other, and two drag link ends that two pawls draw the horse card, 180 ° of angles each other.
The purpose of this utility model is to provide card a kind of two, that the general combined type of three-jaw draws horse for the flight-line maintenance industry.
The design philosophy of this utility model is that existing three-jaw and two pawl cards are combined into one, promptly divide the position, angle equally between three drag link end A, B, two drag link end B, the C among the C of 120 ° of angles each other at original three-jaw card, be connected with four-pull-rod end D, make itself and drag link end A be in collinear two ends, the common port center of above-mentioned four drag link ends has the push rod screw.
Draw the horse card according to above-mentioned design, it is one that three-jaw, two pawls are drawn Ma Gongnengji, when need three-jaw function, can respectively penetrate pull bar at A, B, three drag link ends of C and form angle 120 ° three-jaw each other,, can penetrate pull bar at two drag link ends of A, D if when only being allowed two pawls by the inloading part surrounding space, the formation angle is 180 ° two pawls, convenient working has been avoided changing the operation of drawing horse, has improved operating efficiency.
In the accompanying drawing, Fig. 1, Fig. 2 have represented that respectively existing combined type three-jaw, two pawls draw the front view of horse card, and Fig. 3 has represented the shape of the utility model card, and Fig. 4 is the side view of Fig. 3.
Among the figure, drag link end A, B, C be 120 ° of angles each other, and the angle between drag link end D and B, the C respectively is that the binding site center of 60 ° of each drag link ends has push rod screw 1; Every drag link end has bar-shaped trough 2.During use, earlier push rod is screwed in screw 1 and withstand on the axle top of being overlapped by inloading part, according to reality 3 bolt draw bars are passed each bar-shaped trough 2 of A, B, C drag link end again, or after 2 bolt draw bars being passed the bar-shaped trough 2 of A, D drag link end, each bolt draw bar end being screwed on the nut card appoints by inloading part rear side edge again, rotate push rod with telescopic spanner, the parts that firmly are enclosed within on the axle can be withdrawed from.
