Abstract
The utility model discloses a double-claw bearing thruster which is an improvement based on the existing bearing thruster. The utility model comprises a supporting lever and two pull claws; the utility model is mainly characterized in that the supporting lever is a straight board-shaped supporting lever made of a steel plate and is processed with a screw hole for assembling a screw rod in the middle; the two pull claws are made of steel plates; the upper end of the supporting lever is provided with a through hole which is slightly larger than the cross section of the supporting lever; the two sides of the middle parts of the pull claws are processed with a screw hole matched with a locating bolt. The utility model has the advantages of reasonable design, simple structure, convenient production and processing, low manufacture cost, and high intensity, is suitable for miniaturization, is portable and durable, and is convenient to be used for a small bearing, in particular to the occasions with small working spaces.
Description
Technical field: the utility model relates to a kind of bearing thruster that is used for the bearing drawing.
Background technology: bearing thruster of the prior art generally all is the three-jaw thruster.This three-jaw thruster structure is comparatively complicated, the manufacturing cost height, and particularly its main part support lever and pulling claw all are cast members, intensity is low, is unsuitable for miniaturization, and is relatively heavier, use underaction, can only be applicable to relatively large bearing, and working space needs spaciousness.Thereby be not suitable for less bearing, more be not easy to use in the narrow occasion of working space.
Summary of the invention: the purpose of this utility model provides a kind of two pawl bearing thrusters, in order to overcome the above-mentioned drawback of existing in prior technology effectively.The purpose of this utility model is to improve realization on the basis of existing technology: it comprises support lever and pulling claw, the straight plate shape support lever of support lever that it is characterized in that it for making by steel plate, the centre is processed with the screw of equipped leading screw, its pulling claw is two, be processed into by steel plate, the upper end is processed with a through hole, and this through hole is a bit larger tham the cross section of support lever; The both sides, middle part of pulling claw are processed with the screw equipped mutually with bolt.During use,, suitably regulate the position of two pulling claws at the support lever two ends by sliding type according to the bearing size of desiring drawing, regulate bolt simultaneously, make bearing that the drag hook of pulling claw will desire drawing promptly, after this can operate equally, until bearing is extracted with existing bearing drawbench.
The utility model is reasonable in design, and is simple in structure, is convenient to production and processing, low cost of manufacture, and the intensity height is particularly suitable for miniaturization, and is light durable, easy to use flexible, is convenient to be used for the narrow occasion of small size bearing, particularly working space.
Description of drawings: accompanying drawing is a three-dimensional structure diagram of the present utility model
The specific embodiment: accompanying drawing has provided a specific embodiment of the present utility model, with reference to the accompanying drawings shown in, 3 is support lever among the figure, the straight plate shape support lever of this support lever 3 for making by steel plate, the centre is processed with the screw of equipped leading screw, is equipped with leading screw 4.Its pulling claw 1 is two, is processed into by steel plate, and the upper end is processed with a through hole, and this through hole is a bit larger tham the cross section of support lever 3, is set with the two ends that are placed in support lever 3; The both sides, middle part of pulling claw 1 all are processed with the screw equipped mutually with bolt, are equipped with bolt 2.
