Abstract
The utility model provides a bearing press-in device comprising a pressing sleeve, a pressing head, a bearing seat, a bearing and a support piece. The pressing sleeve is connected with the upper portion of the pressing head in a sleeved mode. The bearing seat is connected with the lower portion of the pressing head in a sleeved mode. The bearing is arranged between the pressing head and the support piece in a concentric mode. The bearing press-in device guarantees that the center line of the bearing and the center line of a bearing hole are in the same straight line, so as to avoid that the bearing is free of effectiveness due to the fact that the bearing is pressed and damaged. Processing accuracy and a rate of finished products are improved, and meanwhile high quality and high-efficiency assembling operations are achieved.
Description
Technical field
The utility model relates to the machining technique field, specifically, is a kind of bearing press-in device.
Background technology
At present, for a large amount of various force fit insertion assembling works that exist in the electronic product assembling, assembling such as bearing outer ring and bearing block, concrete grammar is that pressure head is directly acted on the bearing face, this assembly method is not owing to being provided with positioner, can not guarantee bearing axis and dead eye center line in assembling process point-blank, often cause bearing outer ring that dead eye is scraped damage, assembly quality is descended.The rigging position precision is high owing to requiring in addition, pressing-in force is large and the reasons such as limitation of this process, and bearing bears larger axis to pressure, often causes bearing badly to be lost efficacy by crushing.So be difficult to so far realize high-quality, high efficiency assembly manipulation.
The utility model content
It is a kind of simple in structure, easy to operate that the utility model provides, and improves the bearing press-in device of craft precision and yield rate.
A kind of bearing press-in device of the utility model, comprise gland, pressure head, bearing block, bearing and support member, described gland socket pressure head top, described bearing block socket pressure head bottom, between described pressure head and the support member bearing is installed, the axial length of described pressure head is greater than bearing block, and the lower edge of pressure head lower edge and bearing block is concordant; The gland axial length is greater than pressure head, the internal diameter equal and opposite in direction of described gland and bearing block, and the diameter of pressure head is slightly less than the bearing block internal diameter.
The utility model further improves and is: described support member be internal diameter less than the internal diameter of bearing, the external diameter of support member is greater than the round tube of bearing outside diameter.
The utility model further improves and is: be provided with annular groove in described support member upper surface, bearing is installed on the annular groove.
The beneficial effects of the utility model are: because gland socket pressure head top, bearing block socket pressure head bottom, and the setting of placing with one heart bearing between pressure head and the support member.In assembling process, the pressure mean effort forms annular stress surface on bearing block, guarantees bearing axis and dead eye center line point-blank.This design also makes capacity between bearing, and bearing does not bear axial compressive force, has avoided bearing badly to be lost efficacy by crushing.Not only improve craft precision and yield rate, and realize high-quality, high efficiency assembly manipulation.
Description of drawings
Fig. 1 is cross-sectional schematic of the present utility model.
Wherein, 1-gland, 2-pressure head, 3-bearing block, 4-bearing, 5-support member, 6-annular groove.
The specific embodiment
As shown in Figure 1, a kind of bearing press-in device that the utility model provides comprises gland 1, pressure head 2, bearing block 3, bearing 4 and support member 5, described gland 1 socket pressure head 2 tops, described bearing block 3 socket pressure heads 2 bottoms are placed bearing 4 with one heart between described pressure head 2 and the support member 5.
The axial length of described pressure head 2 is greater than bearing block 3, and pressure head 2 lower edges are concordant with the lower edge of bearing block 3.
Described gland 1 axial length is greater than pressure head 2, and the internal diameter equal and opposite in direction of described gland 1 and bearing block 3, the diameter of pressure head 2 are slightly less than bearing block 3 internal diameters.
Described support member 5 be internal diameter less than the internal diameter of bearing 4, the external diameter of support member 5 is greater than the round tube of bearing 4 external diameters.
In described support member 5 upper surfaces the annular groove 6 that matches with bearing 4 is set also, bearing 4 is installed on the annular groove 6.
When the utility model uses, bearing 4 is positioned in the annular groove 6 of support member 5 upper surfaces, again bearing block 3 is placed on the bearing 4 with one heart, at last with bearing block 3 socket pressure heads 2 bottoms, gland 1 socket pressure head 2 tops.Gland 1 is exerted pressure vertically downward, until finish the assembling of bearing outer ring and bearing block.
