Description

Drawing formula stripping attachment

Technical field

The utility model relates to the instrument that a kind of machine repairing benchwork is used during electromechanical equipment in maintenance, and particularly a kind of machine repairing benchwork pulls out annular parts such as tightly being enclosed within bearing on the axle, gear, shaft joint the instrument of usefulness from axle when the maintenance electromechanical equipment.

Background technology

Bearing is arranged in electromechanical equipment, gear, annular parts such as shaft joint, these annular parts are tightly to be enclosed within on the axle of electromechanical equipment, when electromechanical equipment overhauls, often need, dismantle these annular parts down from axle in large quantities, because bearing, gear, cooperating between annular parts such as shaft joint and the axle is interference fits, tightly be enclosed within on the axle, dismantle very difficult, when dismounting, sometimes be with common stripping attachment dismounting, because the kind of electromechanical equipment is a lot, the axle of distinct device and the annular element size on the axle, the difference of shape and position is very big, some annular parts is bigger with the bonding strength of axle, the above-mentioned field-strip when common stripping attachment can not adapt to dynamo-electric overhaul of the equipments well.In the prior art, not when electromechanical equipment overhaul, conveniently do not use and be suitable for the adjustable instrument of combined type that the annular parts such as bearing, gear, shaft joint to different size, shape and position on the different electromechanical equipment axles are dismantled, in the electromechanical equipment maintenance process, during annular parts such as mounting or dismounting bearing, gear, shaft joint, because there is not suitable stripping attachment, the maintainer knocks and pulls out sled dismounting with instruments such as hand hammer, lever are rigid, inefficiency not only, expense is big, also can cause damage to electromechanical equipment.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of high efficiency, and expense is little, can not cause the drawing formula stripping attachment of damage to electromechanical equipment.

The utility model is realized with the following method.

It is the crossbeam of rectangle that drawing formula stripping attachment has the cross section, on in the middle of the crossbeam, below between internal thread hole is arranged, be rotary with in the internal thread hole and have externally threaded push rod, a crossbeam left side, on the right both sides, below between have respectively the symmetry strip hole, be installed with drawing bolt and drag hook in the strip hole of every side, it is the bull drilling and backward pulls of rectangle that drag hook has the cross section, one end of bull drilling and backward pulls has hook-type drawing head, the other end is connected with bolt, the external diameter of bolt head is greater than the width of strip hole, between bull drilling and backward pulls, be with quadrangle hoop frame, the hoop frame has a left side, right end plate, there is circular hole the both sides of end plate, be connected with bolt between the corresponding circular hole of two end plates, the bolt head external diameter of drawing bolt is greater than the width of strip hole, the other end of drawing bolt be connected with stack on, following two blocks of supporting plates, supporting plate has towards strip gab on one side, the strip gab both sides of a supporting plate are evenly equipped with three screws that match with screw rod respectively along the length direction of strip gab, the strip gab both sides of another piece supporting plate, there is a screw that matches with the screw of above-mentioned supporting plate the centre of strip gab.

The utility model can cooperate with the crossbeam that is rotary with push rod in the internal thread hole and drag hook to be gone up drawing from the axle of equipment and goes out the annular parts, be rotary with in the also available internal thread hole crossbeam of push rod and drawing bolt and supporting plate from the axle of equipment upward drawing go out the annular parts.

Cooperate from the axle of equipment with the crossbeam that is rotary with push rod in the internal thread hole and drag hook and to go up a drawing when going out the annular parts, the crotch of the hook-type drawing head of drag hook is relatively inserted strip hole, crotch is below crossbeam, bolt head is on crossbeam, relative crotch is hooked on the annular parts on the equipment axis one side towards equipment, the push rod lower end that is spun on internal thread hole is withstood on the spindle nose end face, with the hoop frame bull drilling and backward pulls is trapped among in the hoop frame, continue rotary screw, the lower ends downward motion of screw rod is the bearing that tightly is enclosed within on the axle, gear, annular parts such as shaft joint pull out from axle.

As the bonding strength of annular parts and axle when big, being rotary with the crossbeam of push rod and drawing bolt and supporting plate in the available internal thread hole goes up a drawing from the axle of equipment and goes out the annular parts, the drawing bolt is inserted strip hole, bolt head is on crossbeam, in the screw on the screw-in supporting plate of drawing bolt lower end, the one side of the annular parts on the opening of the supporting plate insertion equipment axis towards equipment, the push rod lower end that is spun on internal thread hole is withstood on the spindle nose end face, continue rotary screw, the lower ends downward motion of screw rod, the bearing that tightly is enclosed within on the axle, gear, annular parts such as shaft joint pull out from axle, if when the bonding strength of annular parts and axle was bigger, available two supporting plate openings relatively were connected on the drawing bolt.

The utility model can pull out annular parts such as bearing, gear, shaft joint easily from axle, high efficiency, and expense is little, can not cause damage to electromechanical equipment.The strip hole that symmetry is arranged respectively between the above and below of the utility model crossbeam both sides, go for the dismounting of annular parts such as different bores and position bearing, gear, shaft joint, the utility model has drawing bolt and supporting plate, can disassemble from axle than the circle ring parts bonding strength.

Below in conjunction with accompanying drawing, the utility model is further described.
