The utility model has the advantages of simple structure, small size, and convenient operation; the collet, a mandrel and the bearing are not damaged in the maintenance process of the utility model.
Description
This utility model belongs to the maintenance tool of medical apparatus and instruments, and what relate generally to is a kind of high-speed dental drill handset bearing handling instrument.
As everyone knows, generally all need use a pair of high-precision rolling bearing that can turn round under high speed in the high-speed dental drill mobile phone, its rotating speed is the consumable accessory in the mobile phone up to ten thousand rev/mins of 30-40, needs often to change.Because this rolling bearing is the high accuracy device, price is higher, thereby will guarantee to cause axle, collet chuck and damage of the bearing in the replacing process, otherwise can shorten the working life of bearing, even a whole set of mobile phone is scrapped, and causes unnecessary economic loss.At present because of still there not being the specific purpose tool of this respect, thereby bring many inconvenience to the work of maintainer and odontologist.
The purpose of this utility model promptly produces thus, proposes a kind of high-speed dental drill handset bearing handling instrument.This handling instrument not only volume is little, simple in structure, convenient to operation, and can not cause damage to becoming axle, collet chuck and bearing.
For achieving the above object, this utility model is achieved through the following technical solutions: its mainly by the collet chuck puller, pull out son and depressor is formed, described collet chuck puller comprises sleeve and removal rod, sleeve is a cylinder, its internal diameter and collet chuck external diameter are little matched in clearance, and the termination of replacing bar can be inserted in the eyelet of collet chuck rear end; The described son that pulls out comprises and pulls out sub-frame and pull out sub-push rod, the upper transverse frame center of pulling out sub-frame has connecting hole, have the U-shaped hole on the lower transverse frame corresponding with it, pull out sub-push rod and pull out sub-frame and be connected by connecting hole, the upper end of pulling out sub-push rod is a rotary handle, the lower end is provided with locating tip for kissing the boss structure of joining with circle in the bearing at the center of boss front end; Described depressor comprises depressor frame, depressor bar and depressor head, the upper transverse frame center of depressor frame has connecting hole, the lower transverse frame corresponding with it is provided with locating hole, the depressor bar is connected by connection holes with the depressor frame, the upper end of depressor bar is a rotary handle, the lower end connects with an end of depressor head, can place bearing in the other end of depressor head, and circle is boss structure in it.
This utility model is skillfully constructed, simple in structure, volume is little, easy to carry, simple to operate, it is in the process of changing bearing, disassemble with the end cap of collet chuck puller earlier collet chuck, the one-tenth axle in it and on bearing take out, and then the bearing that has damaged is extracted from becoming axle with pulling out son, last reuse depressor is assembled to into new bearing on the axle.Whole process a few minutes just can finish, and need not the specialized maintenance personnel and all can operate.Because it be specific purpose tool, thus its can be in maintenance process to collet chuck, become axle and bearing not cause damage, avoided economic loss, filled up the blank that domestic dental drill keeps in repair does not have specific purpose tool.
This utility model has following accompanying drawing:
Accompanying drawing 1 is the sleeve cutaway view of this utility model collet chuck puller.
Accompanying drawing 2 is the removal rod sketch map of this utility model collet chuck puller.
Accompanying drawing 3 pulls out the minor structure sketch map for this utility model.
Accompanying drawing 4 pulls out son " U " type hatch frame sketch map for this utility model.
Accompanying drawing 5 is this utility model depressor structural representation.
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: present embodiment mainly by the collet chuck puller, pull out son and depressor is formed, collet chuck puller (shown in Fig. 1-2) includes sleeve 1 and removal rod 2, sleeve 1 one is a cylinder, its internal diameter and collet chuck external diameter to be removed are little matched in clearance, replacing bar 2 is cylindrical, and its termination can be inserted in the eyelet of collet chuck rear end.Pulling out son (as described in Figure 3) comprises and pulls out sub-frame 3 and pull out sub-push rod 4, pulling out sub-frame 3 is a square frame, the centre of its upper transverse frame has connecting hole, have 5 (as shown in Figure 4) of " U " shape mouth on the lower transverse frame corresponding with it, the bore that is somebody's turn to do " U " shape mouth 4 has two kinds: a kind of for pulling out the rim of the mouth greatly, can insert the slit between bearing and wind wheel; Another kind of for pulling out the rim of the mouth for a short time, can insert the bear inner ring grooved railway of bearing.Pull out sub-push rod 4 and be threaded by the connecting hole that pulls out on the sub-frame 3 with pulling out sub-frame 3, the upper end of pulling out sub-push rod 4 is a rotary handle, and the boss structure of lower end for joining with circle kiss in the bearing is provided with locating tip at the hub head end of boss; Depressor comprises depressor frame 6, depressor bar 7 and depressor head 8, depressor frame 6 is a square frame, the centre of its upper transverse frame has connecting hole, the lower transverse frame corresponding with it is provided with locating hole 9, depressor bar 7 is threaded by the connection holes on the depressor frame 6, and the one end is a rotary handle, and the other end connects with the threaded one end of depressor head 8, can place bearing in the other end of depressor head 8, circle is boss structure in it.For avoiding the countershaft damage of manufacturing into, the protruding interior cover of circle in it as the corresponding bearing in position.Present embodiment in use, collet chuck is packed in the sleeve 1 of collet chuck puller, again an end of removal rod 2 is inserted in the eyelet of collet chuck rear end, little firmly beaing dismantled collet chuck, because the external diameter of collet chuck is little matched in clearance with the internal diameter of sleeve 1, thereby the strength major part of beaing born by the positioning ball on the collet chuck shell, has only seldom partly and evenly born by the collet chuck shell that cooperates with sleeve 1, so just farthest protected the shell of collet chuck, can not cause any distortion and damage it; During the dismounting bearing, if bearing does not have the sequence of sanqu songs within a particular musical mode, just pull out son with big mouth, insert slit between bearings and the wind wheel pulling out " U " shape hole 5 on the sub-frame 3, rotate the rotary handle that pulls out on the sub-push rod 4 by hand, continue rotation in the centre bore that locating tip on the sub-push rod 4 places into axle and just can get off the bearing removal of damage pulling out; If bearing is the sequence of sanqu songs within a particular musical mode, just pull out son with osculum, " U " shape mouth 5 that pulls out on the sub-frame 3 is inserted on the bear inner ring grooved railway of bearing, the rotary handle of sub-push rod 4 is pulled out in rotation, the locating tip that pulls out sub-push rod 4 front ends is placed in the centre bore of axle, continue rotation and just can get off the bearing removal of the sequence of sanqu songs within a particular musical mode.During the assembling collet chuck, bearing is placed in the depressor head 8 of depressor, becoming axle to place in the locating hole 9 on the depressor frame 6, rotary handle on the rotation depressor bar 7, bearing is shifted into onto the correct installation site of axle, continue rotation depressor bar 7, can again one be got final product with being installed in the collet chuck bearing press mounting to becoming on the axle.
