Abstract
The utility model provides a nut dismounting and mounting tool which solves the problem that when a fastening hex nut of a drive disc in a rear axle box of a bulldozer is dismounted and mounted, much time and labor are consumed in repeatedly taking a sleeve tool and changing positions of the sleeve tool. The tool is a convex sleeve. A hex through hole is a middle hole of one end of the convex sleeve and the end face of the other end of the convex sleeve is a ring. Multiple radial through holes are distributed in the cylinder face of the convex sleeve. The middle hole is matched with a detached nut in use. The radial through holes are matched with a plate rod in use. The nut dismounting and mounting tool has the advantages of being simple in structure, convenient to use, capable of saving labor and the like.
Description
Technical field
The utility model relates to a kind of nut dismounting tool, especially relates to a kind of instrument of the fastening hex nut dismounting of driving-disc in bulldozer rear axle box.
Background technology
At present, employee carrys out the fastening hex nut of driving-disc in dismounting bulldozer rear axle box with sleeve, during dismounting, first jacket casing on nut, at the sleeve other end, insert extension bar, with plate stem, insert in the radial hole of extension bar afterwards, the moving plate stem of plate is dismantled and assembled nut, because the dismounting position of rear axle box is limited, the corner of plate stem is less than 60 degree, therefore, every plate is moving once must pull out plate stem, takes out sleeve and extension bar and rotates after an angle, repeat again said procedure, perseveration like this, time and effort consuming, inefficiency.
Summary of the invention
The purpose of this utility model is just to provide a kind of nut dismounting tool, and it can improve the operating efficiency of dismounting nut effectively.
The purpose of this utility model is achieved in that described nut dismounting tool is convex sleeve, and one end mesopore of described convex sleeve is hexagon through hole, and the end face of the other end is annulus, is provided with several radial direction through hole on its face of cylinder.
Described mesopore and dismounting nut are used in conjunction with, and described radial direction through hole and plate stem are used in conjunction with.
The utlity model has the feature such as laborsaving simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model structural representation.
Fig. 2 is the cutaway view that the utility model is used status architecture schematic diagram.
The specific embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
As shown in Figure 1: the utility model is convex sleeve 1, the right-hand member mesopore 2 of described convex sleeve 1 is hexagon through hole, and the end face 3 of left end is annulus, is evenly equipped with 12 radial direction through hole 5 on its face of cylinder 4;
Described mesopore 2 is shown in Fig. 2 with dismounting nut 8() be used in conjunction with, described radial direction through hole 5 is shown in Fig. 2 with plate stem 9() be used in conjunction with;
Use procedure of the present utility model is as follows: see shown in Fig. 2, first the mesopore of convex sleeve 12 is enclosed within on the fastening hex nut 8 of the interior driving-disc 7 of bulldozer rear axle box 6, plate stem 9 is inserted in radial direction through hole 5, plate moves plate stem 9, after tommy bar 9 puts in place, only need pull out plate stem 9 and insert another radial direction through hole 5 plate again, not needing convex sleeve 1 to take out rotational angle is dismantled and assembled nut.
