Abstract
A tool for disassembling a bearing in a blind hole is characterized in that the tool comprises a screw, a U-shaped support body, an eccentric positioning sleeve, a positioning nut and a tension nut, wherein a screw head is arranged at one end of the screw while the other end thereof is in threaded connection with a handle; the U-shaped support body is provided with a hole in the middle section thereof and movably sleeved on the screw; the eccentric positioning sleeve is adjacent to the screw head and movably sleeved on the screw; the positioning nut is positioned between the eccentric positioning sleeve and the support body and is in threaded connection with the screw; and the tension nut is positioned between the handle and the support body and is in threaded connection with the screw. As a hand-operated special tool for disassembling the bearing in the blind hole, the utility model has the advantages of reliable tooling positioning during the disassembly, labor conservation, convenient and rapid operation, zero damage to the bearing and a bearing mounting seat hole during the disassembly, as well as high practicability, and can ensure the reutilization of the disassembled bearing.
Description
Technical field
The utility model belongs to the hand-operated tools that uses in maintenance of equipment, repairing or the refitting, relates to a kind of blind hole bearing extracting tool.
Background technology
In the assembling or maintenance of equipment such as engine, 6203 bearings that need will be fitted in the crankshaft rear end blind hole are pulled down, and guarantee not damage bearing (recycling).Dismounting mode of the prior art generally is to adopt ballistic method dismounting blind hole bearing, that is: be hooked on the inner ring of bearing with little hook, and one holds the neck of hook, and another holds and knocks the cover bump neck of hook, with the impulsive force of knocking generation bearing is taken out in blind hole.Adopt this mode, not only the large and small hook of extracting tool volume is fragile, inconvenient operation, labour intensity is big, production efficiency is low, and the bearing that adopts ballistic method to take off can not utilize (having damaged bearing trajectory or steel ball in the unloading process), the crooked damage crankshaft hole of bearing when getting again.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, provide a kind of simple in structure, easy for operation, efficient is high, does not damage the blind hole bearing extracting tool of the special use of bearing and bearing saddle bore.
Content of the present utility model is: a kind of blind hole bearing extracting tool is characterized in that comprising:
A screw rod (1), an end of this screw rod (1) have screw head (7), the other end fixedly connected or that the be connected as a single entity handle (6) that has been threaded; This screw rod (1) is the main body of blind hole bearing extracting tool;
A U-shaped stake body (4), the stage casing of this stake body (4) is porose and be actively socketed on the screw rod (1); This stake body (4) has location and supporting role in the blind hole bearing extracting tool;
An eccentric positioning sleeve (2), this off-centre positioning sleeve (2) is adjacent with screw head (7) and be actively socketed on the screw rod (1);
A setscrew nut (3), this setscrew nut (3) are positioned between eccentric positioning sleeve (2) and the stake body (4) and with screw rod (1) and are threaded; And
A pulling force nut (5), this pulling force nut (5) are positioned between handle (6) and the stake body (4) and with screw rod (1) and are threaded.
In the content of the present utility model: go back movable sleeve on the screw rod (1) between described stake body (4) and the pulling force nut (5) and be connected to packing ring (9), this packing ring (9) can be fixedlyed connected with pulling force nut (5).
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) the utility model adopts static pressure to draw the method for stretching that blind hole bearing is dismantled, and tool locating is reliable during dismounting, and rapid operation and convenient does not damage bearing and bearing mount pad hole in the unloading process, and the bearing under the dismounting can utilize again;
(2) simple in structure, cost is low, and is as the manual specific purpose tool of blind hole bearing dismounting, easy to use, quick, reliable, practical.
Description of drawings
Fig. 1 is the utility model embodiment user mode structural representation;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Among the figure: 1-screw rod, the eccentric positioning sleeve of 2-, 3-setscrew nut, 4-stake body, 5-pulling force nut, 6-handle, 7-screw head, 8-bearing, 9-packing ring.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of blind hole bearing extracting tool, form by following parts:
A screw rod 1, an end of this screw rod 1 have screw head 7, the other end fixedly connected or that the be connected as a single entity handle 6 that has been threaded;
A U-shaped stake body 4, the stage casing of this stake body 4 is porose and be actively socketed on the screw rod 1;
An eccentric positioning sleeve 2, this off-centre positioning sleeve 2 and screw head 7 are adjacent and be actively socketed on the screw rod 1;
A setscrew nut 3, this setscrew nut 3 is threaded between eccentric positioning sleeve 2 and stake body 4 and with screw rod 1; And
A pulling force nut 5, this pulling force nut 5 is threaded between handle 6 and stake body 4 and with screw rod 1.
This blind hole bearing extracting tool is used for engine maintenance, and 6203 bearings that are fitted in the crankshaft rear end blind hole are pulled down, and during use, operating procedure is:
The first step is twisted setscrew nut 3 to stake body 4 one ends with hand, the screw head 7 of screw rod 1 is put in bearing 8 holes of bent axle, snaps on bearing 8 inner rings up to screw head 7;
Second step slided into the cylinder of eccentric positioning sleeve 2 along screw rod 1 in bearing 8 endoporus, made screw rod 1 reliable in bearing 8 endoporus location, and screw rod 1 can rotate in dead eye simultaneously;
The 3rd step, with hand with the eccentric positioning sleeve 2 of setscrew nut 3 rotation directions, up to till eccentric positioning sleeve 2 surfaces contact and screw;
The 4th step, with stake body 4 cover (being inserted in) from the U-shaped openend of stake body 4 on the outer step of crankshaft rear end, simultaneously with pulling force nut 5 usefulness hand-screws to stake body 4, till the surface contacts and screws;
The 5th step, get two open-end wrench or double offset ring spanner, a handle is lived the handle 6 of screw special 1, another rotates pulling force nut 5 (making pulling force nut 5 to the stake body 4 one end application of forces), up to bearing 8 is pulled out (screw rod 1 and screw head 7 and eccentric positioning sleeve 2, setscrew nut 3 pulling bearings 8) in the hole;
The 6th step unscrewed setscrew nut 3 and pulling force nut 5, and the bearing of pulling out 8 is taken off from instrument.
Adopt present embodiment blind hole bearing extracting tool, the location is reliable, and is easy to use, quick, do not damage bearing and bearing mount pad hole.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
