Abstract
The utility model relates to a device used for the installing a retainer. The device comprises a support, wherein a vertical air cylinder is arranged on the support, a piston rod at the lower end of the air cylinder is connected with a pressure head, a retainer base is fixed on the support, the retainer base is arranged right below the pressure head, the air cylinder is connected with a pedal directional valve by an air pipe, and the pedal directional valve is connected with an air source. In the device, the retainer is pressed into a bearing by the pressure head in the way that the air cylinder moves downwards, therefore, the trouble of manual pressing in is avoided, the labor is librated, and the working efficiency is greatly improved; moreover, the retainer is horizontally placed on the retainer base, and the inner ring of the bearing and the outer ring of the bearing are forced vertically at the same time, therefore, the problem that the retainer is easy to deform in the manual assembly is solved. The device is reasonable in structure and convenient in use.
Description
(1) technical field
The utility model relates to and a kind of retainer is installed in device on the bearing.
(2) background technique
Bearing includes inner ring, outer ring, the steel ball between inner ring and outer ring, and be used for fixing the retainer of steel ball, when steel ball is installed, earlier by a minute pearl device steel ball is limited good position, then retainer is pressed into, then steel ball has just been fixed, being pressed into retainer normally, employing manually is pressed into, because retainer is stretched in the bearing, retainer is pressed into comparatively effort, easily the damage finger, operate pretty troublesomely, working efficiency is lower.
(3) summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of device that retainer can be pressed in the bearing, has saved the manual trouble that is pressed into.
The technical scheme in the invention for solving the technical problem is:
A kind of device that is used to install retainer, comprise support, support is provided with the cylinder of vertical direction, the piston rod of cylinder lower end connects a pressure head, be fixed with one retainer base on the support, and described retainer base be positioned at pressure head under, described cylinder connects a foot-operated selector valve by tracheae, described foot-operated selector valve connects source of the gas.
As improvement, described cylinder is a bounce cylinder, the retainer base is provided with retaining ring, the diameter of described retaining ring is identical with the retainer diameter, and the base center convexes with mandrel, described mandrel is coaxial setting with retaining ring, is provided with spring between described mandrel lower end and the retainer base.
As improvement, piston rod connects pressure head by a connecting rod, and the bottom of described pressure head is provided with nylon layer.
During operative installations, retainer is placed on the retainer base, and retainer is positioned, to divide the bearing of steel ball to be placed on the retainer by a minute pearl device, foot-operated selector valve, cylinder moves downward, and it is downward to drive pressure head, at pressure head soon during contact bearing, cylinder buffering is exerted pressure to product, and retainer is motionless, bearing moves down, and is about to retainer and is pressed in the bearing.Retainer assembles successfully, loosens foot-operated selector valve then, and cylinder resets.The diameter of the retaining ring of retainer base is identical with the retainer diameter, then retainer just is placed on and can be used to the location on the retaining ring, the center of base convexes with mandrel, and the diameter of mandrel is identical with the bearing bore diameter size, also be positioned after then bearing is put and do not move, bearing is coaxial with retainer, with bearing and retainer location easy-to-operat, and not slippage in process of press in.The surface of contact that in the bottom of pressure head is pressure head and bearing is provided with nylon layer, can protect bearing injury-free, has avoided being easy to generate in the manual course of working that ball is hindered, raceway groove is hindered phenomenon.Cylinder adopts bounce cylinder, can make bearing not have impact force when stressed, and spring is set below mandrel, can play cushioning effect.In addition, can change the retainer base at the bearing of different size realizes.
The beneficial effects of the utility model are: the utility model moves downward by cylinder, and retainer is pressed in the bearing by pressure head, saved the manual trouble that is pressed into, liberated the labour force, working efficiency is provided greatly, and retainer lies on the retainer base, the inside and outside circle while of bearing and vertically stressed, has solved the yielding problem of hand assembled retainer.The utility model is rational in infrastructure, and is easy to use.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of device that is used to install retainer, comprise support 7, the top of support is provided with the bounce cylinder 1 of vertical direction, the bottom of support is provided with the retainer base 6 that is used for fixing retainer, the piston rod of bounce cylinder 1 lower end connects a pressure head 3 by a connecting rod 2, the lower end of pressure head 3 is provided with nylon layer, retainer base 6 be positioned at pressure head under, retainer base 6 is provided with retaining ring 5, the diameter of retaining ring 5 is identical with the retainer diameter, and the base center convexes with mandrel 4, be provided with spring between mandrel lower end and the retainer base, mandrel 4 is coaxial setting with retaining ring 5, and axle diameter is the size of bearing bore diameter.Bounce cylinder connects a foot-operated selector valve 9 by tracheae 8, and foot-operated selector valve 9 connects source of the gas.
During operative installations, retainer is placed on the retainer base 6, and retainer be fixed the ring 5 the location, to divide the bearing of steel ball to be placed on the retainer by a minute pearl device, and bearing be also located foot-operated then selector valve 9 by mandrel 4, bounce cylinder 1 moves downward, and it is downward to drive pressure head 3, at pressure head soon during contact product, and the bounce cylinder buffering, exert pressure to product, retainer is motionless, and bearing moves down, and retainer is pressed in the bearing.When the size of bearing differs, the size that can change the retainer base realizes.The utility model has been liberated the labour force, has saved the manual trouble that is pressed into, and working efficiency is provided greatly, and retainer is yielding when also having avoided hand-manipulated simultaneously, and the easy ball of bearing is hindered the problem that raceway groove is hindered, and has improved up-to-standard rate.
