Description
Technical field
Servomotor manufacturing technology field is the utility model is related to, is used for servomotor bearing press mounting more particularly, to one kind
Simple frock.
Background technology
Servomotor is a kind of high-accuracy dynamical element, and with the development of industry manufacture, servomotor is in lathe, machine
The application in the fields such as people, medical treatment, space flight is also more and more extensive, so the assembling of the manufacture of servomotor also has to precision.
Servomotor is typically supported by former and later two bearings, and the inner ring of forward and backward bearing is interference fitted with axle
And outer ring and the bearing saddle bore interference fits on end cap, during practical set, fore bearing needs first gland on axle, then
Bearing needs first to be pressed into the bearing saddle bore of end cap.As shown in Figure 1 and Figure 2, bonding press 1 ' passes through the first cylinder 2 ' to prior art
The inner ring of fore bearing 4 ' is pushed so that fore bearing 4 ' is inserted on axle 3 ', bonding press 1 ' pushes rear bearing 6 ' by the second cylinder 5 '
Outer ring rear bearing 6 ' is inserted in the bearing saddle bore 8 ' of end cap 7 ', therefore for different model bearing then need to change it is different
The first cylinder 2 ' and the second cylinder 5 ', cause frock various, bad management is also easily lost, and causes to waste, versatility
Difference, it need to improve.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of to be used for servo motor shaft
The simple frock of pressure-bearing dress, it is simple in construction, it is versatile, the forward and backward bearing of servomotor can be pressed, it is economical and practical.
To reach above-mentioned purpose, the technical solution of the utility model is：It is a kind of to be used for the simple of servomotor bearing press mounting
Frock, including be arranged concentrically successively from outside to inside outer cylinder, pedestal cylinder, inner cylinder, the pedestal cylinder inner wall is provided with the
One external screw thread and outer wall are provided with the first internal thread, and the inner circle drum outer wall, which is provided with the second internal thread and coordinated with the first external screw thread, to be joined
Connect, the outer cylinder inwall is provided with the second external screw thread and coupled with the first screw-internal thread fit, and the inner cylinder bottom surface is the first circle
Cambered surface, the outer cylinder bottom surface are the second arc surface.
The pedestal cylinder is stainless steel material.
The inner cylinder, outer cylinder are copper product.
The inner cylinder, the top surface of outer cylinder are below the top surface of pedestal cylinder.
The beneficial effects of the utility model are：The utility model is simple in construction, versatile, can be pressed servomotor
Forward and backward bearing, it is economical and practical, convenient management, for the bearing of different model, only it need to change different inner cylinders, outer cylinder i.e.
Can, it is convenient and practical, and be also unlikely to change whole frock when inner cylinder, outer cylinder have to damage, effectively save cost, it is worth pushing away
Extensively.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Fig. 3~Fig. 5, a kind of simple frock for servomotor bearing press mounting, it is characterised in that：Including from outer
To the interior outer cylinder 3 being arranged concentrically successively, pedestal cylinder 1, inner cylinder 2, the inwall of pedestal cylinder 1 is provided with the first external screw thread 11
And outer wall is provided with the first internal thread 12, the outer wall of inner cylinder 2, which is provided with the second internal thread 21 and coordinated with the first external screw thread 11, to be joined
Connect, the inwall of outer cylinder 3, which is provided with the second external screw thread 31 and coordinated with the first internal thread 12, to be coupled, and the bottom surface of inner cylinder 2 is
First arc surface 22, when the bottom surface of inner cylinder 2 pushes the inner ring of fore bearing, scuffing and impression will not be caused to the inner ring of fore bearing,
The bottom surface of outer cylinder 3 is the second arc surface 32, will not be to the outer of rear bearing when the bottom surface of outer cylinder 3 pushes the outer ring of rear bearing
Circle causes to scratch and impression.
The pedestal cylinder 1 is stainless steel material, will not be got rusty, service life length.
The inner cylinder 2, outer cylinder 3 are copper product, and copper product is than servomotor bearing inner ring, the material hardness of outer ring
It is low, the inner ring of bearing, outer ring will not be caused to scratch and impression.
The inner cylinder 2, the top surface of outer cylinder 3 are below the top surface of pedestal cylinder 1 so that the face of bonding press effect is
The top surface of pedestal cylinder 1.
The utility model when in use, when needing to carry out fore bearing gland, screws outer cylinder 3 so that outer upwards
The bottom surface of cylinder 3 is higher by the bottom surface of inner cylinder 2, as shown in figure 4, bonding press acts on the top surface of pedestal cylinder 1, the bottom of inner cylinder 2
Face is supported to the inner ring of fore bearing, press downward actuation and gland work can be achieved, when Bearing housing after needing to carry out, to backspin
Twist outer cylinder 3 so that the bottom surface of outer cylinder 3 is less than the bottom surface of inner cylinder 2, as shown in figure 5, bonding press acts on pedestal cylinder 1
Top surface, the bottom surface of outer cylinder 3 supported to the outer ring of rear bearing, and gland work can be achieved in press downward actuation.
It the foregoing is only the preferable embodiment of the utility model, but the scope of protection of the utility model not office
It is limited to this, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, it should all cover within the scope of protection of the utility model.
