Abstract
The utility model relates to a multi-functional three-jaw pull bearing puller, which comprises a guide screw, a central horse and three pull jaws; a central hole is arranged at the center of the central horse; the central hole is provided with thread matched with the guide screw; each pull jaw is provided with a plurality of connecting holes; the three pull jaws are evenly distributed around the guide screw; horses corresponding to the pull jaws are arranged along the central radial direction of the central horse; the horses are provided with connecting flakes which are connected through bolts; the other end of each connecting flake is connected with the connecting holes of the pull jaws through bolts; through the rotation of the guide screw, the height and the depth of the three-jaw puller can be adjusted to disassemble different mechanical parts including gears, belt wheels and bearings, so as to avoid unnecessary damage to the workpiece caused by mandatory disassembly; besides, the puller is easy to use, so as to facilitate the entire maintenance.
Description
Technical field
The utility model relates to a kind of handling instrument, the thruster of loading and unloading such as specifically a kind of bearing, gear.
Background technology
In mechanical industry maintenance, usually run into the separation dismounting of workpiece such as bearing, general during dismounting just with two pawls or three-jaw thruster, but different because of concrete situation, be difficult to change as the circle pin, inapplicable dismounting does not have the workpiece of central point.Present employed thruster, generally all be applicable to large-scale and mechanical field-strip single variety, be not suitable for maintenance to little workpiece, if and in maintenance process with instruments such as tup to workpiece such as bearing force the dismounting, make damages such as bearing easily, so that greatly reduce the service life of machine, in service work, get half the result with twice the effort.
Summary of the invention
The purpose of this utility model provides and a kind ofly pulls effective, simple structure, multi-functional three-jaw easy to use draws a yard bearing thruster.
For achieving the above object, the utility model is by the following technical solutions:
Multi-functional three-jaw described in the utility model draws a yard bearing thruster, comprise leading screw, center foot rest, pulling claw, the center of center foot rest is provided with centre bore, centre bore is provided with the screw thread that matches with leading screw, and described pulling claw is provided with a plurality of connecting holes, and described pulling claw is three, be distributed on around the leading screw, described center foot rest radially is provided with along its center and the corresponding foot rest of pulling claw, is rotatably connected to brace on the foot rest, and the other end of described brace is connected with connecting hole on the pulling claw.
As a kind of improvement, the top of described pulling claw is provided with the tack that extends laterally, and the bottom is provided with crooked to the inside drag hook, and the bottom surface of described drag hook is the plane.
As further improvement, described pulling claw is provided with two connecting holes.
As further improvement, the top of described leading screw is regular polygon, and is provided with the circular hole that can insert pole, and the bottom of described leading screw is inverted circular cone.
As further improvement, also be provided with a standby foot rest on the foot rest of described center.
Owing to adopted technique scheme, described three-jaw thruster, regulate the height and the degree of depth of three-jaw thruster by rotational lead screw, realize dismounting to different mechanical workpieces such as gear, belt pulley and bearing, prevent that compulsory dismounting from bringing unnecessary harm to these workpiece, and Ei is easy to use, and whole service work is got twice the result with half the effort.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of center foot rest among Fig. 1;
Fig. 3 is a user mode reference diagram of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Multi-functional three-jaw draws a yard bearing thruster, comprises leading screw 1, center foot rest 2, pulling claw 3, and pulling claw is slit into type with iron plate vapour.The center of center foot rest 2 is provided with centre bore, and centre bore is provided with the internal thread that matches with leading screw 1, and described pulling claw 3 is provided with two connecting holes 31, can change connecting hole 31, so that satisfy the profundity of different workpieces according to the needs of workpiece.Described pulling claw
It is three, be distributed on around the leading screw 1, described center foot rest 2 radially is provided with along its center and pulling claw 3 corresponding foot rests 21, be connected with brace 4 with screw on the foot rest 21, the other end of described brace 4 is connected with connecting hole 31 usefulness screws on the pulling claw 3, described brace 4 usefulness compound dies are washed into shape through plate, the institute towards the object unanimity, the precision height.
The top of described pulling claw 3 is provided with the tack that extends laterally, the bottom is provided with crooked to the inside drag hook, described drag hook is convenient to firmly grasping workpiece such as bearings inwards, prevent that workpiece drops because of grabbing shakiness in unloading process, defective work piece, the bottom surface of described drag hook are the plane, also can pull the little object in gap, be convenient in operating process, adapt to different workpiece.
The top of described leading screw 1 is regular polygon, be generally regular hexagon, the centre is provided with the circular hole that can insert pole, can insert pole and come rotational lead screw 1, like this can be laborsaving, reduced labour intensity, the bottom of described leading screw 1 is inverted circular cone, the central shaft of leading screw 1 overlaps with the central shaft of center foot rest, has improved the precision of pulling, so that is difficult for making workpiece to sustain damage.
Also be provided with a standby foot rest 22 on the described center foot rest 2, promptly all available this center foot rest 2 of two pawl thrusters or three-jaw thruster serves many purposes thruster.
