Abstract
The present invention relates to a kind of stop device, it comprises axis body, the collar, the inner headed face of the collar and the periphery of axis body are assembled together, it is characterized in that, also comprise scotch, elastic device, the inner circle of the described collar position corresponding with the cylindrical of axis body is respectively equipped with groove, described scotch and elastic device are placed in the groove of the collar and axis body, one end of elastic device and the collar or axis body link together, the other end and scotch link together, described elastic device compresses the degree of depth that height sum that is rear and scotch is less than or equal to the collar at its place or the groove of axis body completely.The present invention is provided with scotch between the collar and axis body, can carry out axial location to the assembly of the collar and axis body.Assembling process of the present invention is simple to operation, effectively can improve the reliability that axis body assembles with cover interannular.
Description
Technical field
The present invention relates to a kind of stop device.
Background technology
Axis body class part is widely used in all kinds of mechanical, electric information product with the assembly structure of cover ring parts, and this structure is generally all in the key position of various product, and the cylindrical as transmission position, key components and parts is protected.Interannular is many is realized by transition, interference fit with cover at axis body for this class formation.Often through by collar thermal expansion, hydraulic buckling during assembling, or the process of axis body cold events is realized assembling.The factors such as the deviation of processing dimension, the distortion of part, the change of mechanical performance, the change of working order all can cause between transition, the axial workpiece of interference fit and cover ring parts and there is the hidden danger of relative displacement.
Summary of the invention
The object of the invention is to overcome above defect, a kind of a kind of stop device reducing axial workpiece and produce relative displacement after overlapping lopps Assembly of the parts is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of stop device, it comprises axis body, the collar, scotch, elastic device, the inner headed face of the collar and the periphery of axis body are assembled together, groove is respectively equipped with in the inner circle of the collar and the corresponding position of the cylindrical of axis body, described scotch and elastic device are placed in the groove of the collar and axis body, one end of elastic device and the collar or axis body link together, the other end and scotch link together, described elastic device compresses the degree of depth that height sum that is rear and scotch is less than or equal to the collar at its place or the groove of axis body completely.
In order to be beneficial to the installation of processing and multiple scotch and elastic device, described groove is cannelure.
In order to be beneficial to installation, one end and the axis body of described elastic device link together, and the other end and scotch link together.
Described elastic device comprises spring, spring housing and plunger, described scotch is provided with hole, and spring housing is fixedly connected in the hole of scotch, and spring is placed in spring housing, one end and the scotch of described spring link together, and the other end and the plunger of spring link together.
In order to the displacement preventing stop device from producing circumferencial direction in cannelure, also comprise fixture block, the position of installing scotch corresponding at axis body or the collar is axially arranged with locating slot, the width of fixture block is greater than the width of scotch, described fixture block and scotch are fixed together, and described fixture block is placed in locating slot.
The invention has the beneficial effects as follows, between the collar and axis body, be provided with scotch, axial location can be carried out to the assembly of the collar and axis body.Scotch is equipped with fixture block and size and rigging position coordinate with axis body, can guarantees that stop device is relative fixing in a circumferential direction with the assembly of the collar and axis body.Elastic device can make scotch be convenient to install and coordinate with scotch, plays the effect of stop.Assembling process of the present invention is simple to operation, effectively can improve the reliability that axis body assembles with cover interannular.
