The bearing press-in device of belt pulley
Technical field
The utility model relates to a kind of assembling device of belt pulley, relates in particular to a kind of bearing press-in device of belt pulley.
Background technology
At present, during bearing assembling in belt pulley and its, generally all be through manually bearing being pressed into belt pulley, consume power relatively and workload is big.Simultaneously, in assembling process manually,, cause damage of the bearing easily, and this assembly cost manually is high, can't carry out streamline production if unbalanced to the bearing application of force.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of assembling speed fast and guarantee the bearing press-in device of the belt pulley of assembly quality.
The bearing press-in device of the utility model belt pulley comprises frame, and said frame is provided with cylinder; The cylinder lower end is provided with gland; The gland below is placed with belt pulley, and belt pulley is fixed on the locating rack of frame bottom, aims at the axis hole of belt pulley under the gland; And suitable with the axis hole size, be provided with the parts of bearings that is pressed into by cylinder in the axis hole.
Said parts of bearings comprises lower bearing, top cover, the upper bearing (metal) that is pressed into axis hole successively.
Said gland is provided with a circle annular protrusion over against an edge of axis hole, and the width of annular protrusion is consistent with the bearing outer ring width.
Adopt the bearing press-in device of the belt pulley of the utility model; Change existing manual hand assembled parts of bearings and belt pulley into the cylinder automation parts of bearings is pushed belt pulley; Improved pack into the speed of belt pulley of parts of bearings greatly; Practice thrift the production time, improved production efficiency, reduce production costs.Simultaneously, the fit of this automation has also improved the assembly quality of parts of bearings and belt pulley.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the bearing press-in device of the utility model belt pulley.
The specific embodiment
As shown in Figure 1, the utility model comprises frame 1, and said frame 1 is provided with cylinder 2; Cylinder 2 lower ends are provided with gland 3; Gland 3 belows are placed with belt pulley 4, and belt pulley 4 is fixed on the locating rack 5 of frame 1 bottom, aim at the axis hole 41 of belt pulley 4 under the gland 3; And suitable with axis hole 41 sizes, be provided with the parts of bearings 6 that is pressed into by cylinder 2 in the axis hole 41.
Adopt above structure; Change existing manual hand assembled parts of bearings 6 and belt pulley 4 into cylinder 2 automations parts of bearings 6 is pushed belt pulley 4, improved pack into the speed of belt pulley 4 of parts of bearings 6 greatly, practice thrift the production time; Improved production efficiency, reduced production costs.
Said parts of bearings 6 comprises lower bearing 61, top cover 62, the upper bearing (metal) 63 that is pressed into axis hole successively.
Said gland 3 is provided with a circle annular protrusion 31 over against an edge of axis hole 41; The width of annular protrusion 31 is consistent with upper and lower bearing outer ring 631,611 width; When fit on, lower bearing 63,61 and belt pulley 4; Annular protrusion 31 on the gland 3 matches with upper and lower bearing outer ring 631,611,3 pairs of upper and lower bearing 63,61 application of forces of gland of being more convenient for.
When running in bearings parts 6 and belt pulley 4; Earlier lower bearing 61 is placed on the axis hole 41 of belt pulley; Cylinder 2 drives the axis hole 41 that gland 3 is pressed into lower bearing 61 belt pulley then; To push up cover 62 then and be placed on this lower bearing 61 tops, last cylinder 2 drives the axis hole 41 that gland 3 is pressed into upper bearing (metal) 63 belt pulley again, places cover 62 tops, top.
