Abstract
A tool for detaching an engine belt pulley relates to a tool for detaching the belt pulley. The utility model aims at solving the problem of low engagement accuracy and unreliable use of a pulling jaw and a beam which are used for detaching the engine belt pulley and inconvenience and easy damage of the detaching tool adopting three pulling jaws. The tail of each pulling jaw is provided with a circular through hole; a key is arranged on the side wall in each circular through hole and integrated with the pulling jaw; two ends of the external side wall of a beam are respectively provided with a key slot matched with the key; two ends of the beam respectively penetrate the corresponding circular through hole on the pulling jaw; the pulling jaw is connected with the beam through the key; the center portion of the beam is provided with a center thread through hole; and a screw rod is threaded with the center thread through hole of the beam. The utility model is used for detaching the belt pulley on the engine.
Description
Technical field
The utility model relates to a kind of instrument of dismantling belt pulley.
Background technology
At present, the pulling claw of the instrument that is adopted during engine belt pulley in dismounting and crossbeam mostly are square hole and cooperate or adopt the screw immovable fitting, and quality of fit is low and use unreliablely, and adopts the extracting tool use inconvenience, fragile of three pulling claws.
The utility model content
The purpose of this utility model provides a kind of instrument of dismantling engine belt pulley, low and use unreliablely with the pulling claw that solves at present the instrument that is adopted when the dismounting engine belt pulley with the crossbeam quality of fit, and adopt the extracting tool of three pulling claws to use inconvenience, flimsy problem.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described instrument is made of two pulling claws, crossbeam and screw mandrels, and the head end of described screw mandrel is provided with top; The afterbody of each pulling claw is provided with manhole, sidewall in each manhole is provided with key, and described key and pulling claw are made one, the two ends of the lateral wall of described crossbeam are provided with a keyway that is complementary with key, the manhole on the corresponding pulling claw is passed at the two ends of described crossbeam respectively, and pulling claw is connected by key with crossbeam, and the middle part of described crossbeam is provided with the center tapped through hole, and described screw mandrel is threaded with the center tapped through hole of crossbeam.
The utlity model has following beneficial effect: pulling claw of the present utility model adopts manhole to cooperate with crossbeam and is connected with crossbeam by key, and type of attachment is reliable, and the quality of fit height does not turn to during use, does not fall key; Simultaneously the utility model adopts two pulling claws just to finish work, and two pulling claws use comparatively convenient, not fragile.
Description of drawings
Fig. 1 is an overall structure front view of the present utility model, and Fig. 2 is the overall structure front view of pulling claw in the utility model, and Fig. 3 is the vertical view of Fig. 2, and Fig. 4 is the overall structure front view of the utility model middle cross beam.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1-Fig. 3 present embodiment is described, the instrument of present embodiment is made of two pulling claws 1, crossbeam 2 and screw mandrel 3, and the head end of described screw mandrel 3 is provided with top 3-1; The afterbody of each pulling claw 1 is provided with manhole 1-1, sidewall in each manhole 1-1 is provided with key 1-2, and described key 1-2 and pulling claw 1 are made one, the two ends of the lateral wall of described crossbeam 2 are provided with a keyway 2-1 who is complementary with key 1-2, the manhole 1-1 on the corresponding pulling claw 1 is passed at the two ends of described crossbeam 2 respectively, and pulling claw 1 is connected by key 1-2 with crossbeam 2, the middle part of described crossbeam 2 is provided with center tapped through hole 2-2, and described screw mandrel 3 is threaded with the center tapped through hole 2-2 of crossbeam 2.Sidewall in the manhole 1-1 is provided with to such an extent that key 1-2 is processed into by linear cutting equipment.
Wherein the specific embodiment two: in conjunction with Fig. 2 and Fig. 3 present embodiment is described, the radius of the manhole 1-1 on the afterbody of each pulling claw 1 of present embodiment is 20mm.Other compositions and annexation are identical with the specific embodiment one.
The specific embodiment three: in conjunction with Fig. 2 and Fig. 3 present embodiment is described, the width of the described key 1-2 of present embodiment is 5mm.Other compositions and annexation are identical with the specific embodiment one or two.
Operation principle: during the dismounting belt pulley, two pulling claws 1 are placed on belt pulley below, and the pawl of pulling claw 1 stem catches on the cylindrical of belt pulley, this moment leading screw 3 with a corresponding setting of belt pulley cover, make leading screw 3 motions withstand the axle of belt pulley cover with spanner, separate with axle until belt pulley.
