Description
Technical field
The utility model relates to machine for automatically assembling needle bearing technical field, especially a kind of machine for automatically assembling needle bearing holder fixing device.
Background technique
Needle bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor, and its main function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.Because the needle roller assembly process of current domestic needle bearing still depends on manual operation, manual operation difficulty is larger, the cost of cost is high, and it is not high to assemble successful bearing quality, the inefficiency of assembling, and also easily occur security incident in the process of manual assembly, existing needle bearing assembling machine holder fixing device result is complicated, and equipment cost is high.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the problem of traditional retainer fixture structure complexity, now providing a kind of needle bearing automatically to turn and joining machine holder fixing device.
The utility model solves the technological scheme that its technical problem adopts: a kind of machine for automatically assembling needle bearing holder fixing device, comprise rotating shaft, described rotating shaft is provided with the first annular protrusion successively, annular groove and the second annular protrusion, described first annular protrusion and the second annular protrusion are equipped with some blind holes, Compress Spring is provided with in described blind hole, the top of described Compress Spring is provided with steel ball and steel ball is positioned at the aperture place of blind hole, the diameter in described aperture is slightly less than the diameter of steel ball, its way rushes rivet hole mouth to make aperture material deformation reach the object of blocking aperture, by two of retainer side racks respectively on first ring connected in star and the second annular groove, now the inwall of retainer can extrude the steel ball in blind hole, reach a kind of effect of interference fit, retainer is fixed in rotating shaft, now rotating shaft connects power mechanism, so retainer can rotate together along with rotating shaft.
Preferably, the blind hole on described first annular protrusion and the second annular protrusion all has two.
Preferably, described blind hole is evenly distributed on the first annular protrusion and the second annular protrusion
The beneficial effects of the utility model are: machine for automatically assembling needle bearing holder fixing device of the present utility model, adopt to be provided with on axle and there is flexible steel ball, with this, retainer is fixed in rotating shaft, the utility model structure is simple, successful, easy to use, cost is low, optimizes the structure of machine for automatically assembling needle bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic diagram of the present utility model;
In figure: 1, rotating shaft, 2, steel ball, 3, retainer, 4, Compress Spring, 5, blind hole, 6, aperture, the 7, first annular protrusion, 8, annular groove, the 9, second annular protrusion.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
A kind of machine for automatically assembling needle bearing holder fixing device as shown in Figure 1, comprise rotating shaft 1, rotating shaft 1 is provided with successively the first annular protrusion 7, annular groove 8 and the second annular protrusion 9, first annular protrusion 7 and the second annular protrusion 9 are equipped with two blind holes 5, Compress Spring 4 is provided with in blind hole 5, the top of Compress Spring 4 is provided with steel ball 2 and steel ball 2 is positioned at aperture 6 place of blind hole 5, rush rivet hole mouth 6, the diameter that after making the material deformation in aperture 6, diameter is slightly less than steel ball 2 reaches the object of blocking aperture 6.
Embodiment 2
With the difference of embodiment 1, embodiment 2 is that blind hole 5 is evenly distributed on the first annular protrusion 7 and the second annular protrusion 9.
Working principle of the present utility model is set forth with embodiment 2:
By two of retainer 3 side racks respectively on first ring connected in star 8 and the second annular groove 8, now the inwall of retainer 3 can extrude the steel ball 2 in blind hole 5, reach a kind of effect of interference fit, retainer 3 is fixed in rotating shaft 1, now rotating shaft 1 connects power mechanism, so retainer 3 can rotate together along with rotating shaft 1, then coordinate other devices of machine for automatically assembling needle bearing, complete the assembling of needle bearing.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
