Description
Technical field
The utility model belongs to technical field of bearing processing.
Background technology
Bearing is in mechanical transmission course, play parts that are fixing and reduction load coefficient of friction.Alternatively, when other parts produce relative motion each other on axle, be used for reducing the fixing parts of coefficient of friction in power transmission process and retainer shaft center.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is supported mechanical rotary body, in order to reduce the mechanical load coefficient of friction of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Need to carry out outer ring to it during bearing machining, end face carries out turning, existing bearing is all position processing by pneumatic interior jaw to it, and the shortcoming of this mode is: the situation that dislocation occurs when easily there is clamping shakiness, bearing machining occurs.
Utility model content
The utility model is intended to provide a kind of and clamps the bearing top circle processing tool firm, dislocation is less likely to occur.
Bearing top circle processing tool in this programme, comprise the clamping part and thrust portion that are bolted, the endoporus of clamping part and thrust portion communicates, and is provided with axial cylinder output shaft in clamping part, and this cylinder exports the tip of the axis and is threaded with push rod; Push rod end is connected with pushing block by spring, the slide block spot welding that this pushing block and thrust portion endoporus are slidably matched, and the right-hand member of slide block is the conical surface; Its center in thrust portion is sliding combined with apical axis, and the left end of apical axis is the conical surface, and the right-hand member center of apical axis has the apical pore that coordinate top with cylinder; Be provided with two left travellers in clamping part, be the inclined-plane mated with the apical axis left end conical surface inside left traveller, the outside of left traveller is connected with left expansion block by spring; Be provided with two right travellers in clamping part, be the inclined-plane mated with the slide block right-hand member conical surface inside left traveller, the outside of right traveller is connected with right expansion block by spring.
The beneficial effects of the utility model are: moved and right traveller is radially moved outward by cylinder output shaft promotion push rod, pushing block, slide block, thus made right expansion block give prominence to clamping part, by cover bearing inner wall clamping on the holder portion; Another convenience, the top apical axis that makes of cylinder moves to left in slide block, left traveller is radially moved outward, thus makes left expansion block give prominence to clamping part, clamp further to bearing inner wall.By the clamping of 4 expansion sets, it is more firm that the utility model compares traditional pneumatic interior jaw clamping, not easily loosens dislocation during bearing machining.
Further, described expansion block runs through clamping part, can clamp bearing inner wall.
Further, state push rod right-hand member and have installing hole, pushing block, by spring attachment mounting hole, has cushioning effect.
Further, pushing block right-hand member leaves restriction apical axis and to move to left the stopper slot of distance, prevents apical axis from moving to left excessively.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bearing top circle processing tool embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description 1 comprises: thrust portion 1, clamping part 2, cylinder output shaft 3, push rod 4, pushing block 5, left traveller 6, right traveller 7, left expansion block 8, right expansion block 9, slide block 10, apical axis 11, top 12.
Embodiment is substantially as shown in Figure 1: bearing top circle processing tool, comprises thrust portion 1 and clamping part 2, and this thrust portion and clamping part are cylindrical shape and their endoporus communicates, and thrust portion and clamping part are undertaken fastening by bolt.
Axially be provided with cylinder output shaft 3 at thrust portion endoporus along it, this cylinder exports the tip of the axis and is threaded with push rod 4, and this push rod right-hand member has installing hole, and pushing block 5 is connected to this installing hole by spring.Be provided with two the left travellers 6 and two right travellers, 7, two left travellers radially arranged in clamping part with the inclined-plane coordinated with apical axis left end, two right travellers are with the inclined-plane coordinated with slide block right-hand member.Two left travellers are all connected with corresponding left expansion block 8 by spring, and these two left expansion blocks all run through clamping part, same, and two right travellers are all connected with corresponding right expansion block 9 by spring, and these two right expansion blocks all run through clamping part.
Slide block 10 is sliding combined with in the endoporus of clamping part, the right-hand member of this slide block inserts between two right travellers, the right-hand member of this slide block is the conical surface mated with right traveller, the left end of slide block and pushing block spot welding, the movement of pushing block can make slide block move, this spot welding place forms formation one section of cavity, and left traveller is positioned at this cavity.The central slide of slide block is combined with apical axis 11, and the left end of this apical axis is the conical surface and inserts between two left travellers, and the left end of this apical axis is the conical surface coordinated with left traveller inclined-plane.The right side of apical axis is with apical pore, and the cylinder top 12 at clamping part right-hand member center inserts in this apical pore.Pushing block right-hand member leaves restriction apical axis and to move to left the stopper slot of distance.
The course of work of the present embodiment is as follows: on the holder portion, the top promotion apical axis of cylinder moves to left in slide block inside the inner ring cover of bearing, and the left end of apical axis makes two left travellers outwards move along clamping part footpath, thus promotes corresponding expansion block clamping bearing; Same, cylinder output shaft promotion push rod, pushing block, slide block move to right, and slide block right-hand member makes two right travellers outwards move along clamping part footpath, thus promote corresponding expansion block clamping bearing.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect the effect of the utility model enforcement and the practicality of utility model.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
