Abstract
A kind of shell protection device of encoder, dislocation sealing up and down is formed in the annular projection covered by the sealing gasket base wedge pressure on encoder shell, effectively protection dust, sealing gasket is made using rubber or other elastomeric materials simultaneously, it is set to produce deformation under the fastening pressure of encoder shell and gland, further protect dust and liquid, it is short with the process-cycle, cost is low, the advantages of production efficiency is high, product quality is stable, substantially increases uniformity and stability that encoder uses under adverse circumstances operating mode.
Description
Technical field:
The utility model is related to mechanical field, more particularly to the guard technology of encoder, particularly a kind of encoder it is outer
Shell protector.
Background technology
Existing encoder in severe work condition environment in use, due to encoder degree of protection (IP40 after installation) no
It is enough, cause dirt, foreign matter or liquid to enter decoder internal, problems with can be caused：1st, there are foreign matter entrance, interference sensing
Element, influence output accuracy；2nd, there is dirt entrance, influence circuit and code-disc precision；3rd, there are liquid entrance, encoder damage；With
Upper situation cause encoder repair rate is high, stability difference, it is necessary to spend substantial amounts of manpower and materials to safeguard, cost is high, efficiency compared with
It is low, and unstable product quality.
Utility model content
The purpose of this utility model is to be directed to drawbacks described above of the prior art, there is provided a kind of by encoder degree of protection
Improve to the shell protection device of IP52 standards.
Its main operational principle is that dislocation seals up and down by forming formation in structure in gland and encoder shell, with
And be squeezed by sealing gasket and produce deformation formation interior sealing, effectively prevent external dust or liquid from entering decoder internal.
To achieve the above object, the utility model uses following technical scheme：The shell protection device of encoder, including pressure
Lid, fastener, encoder shell, it is characterised in that the sealing gasket base of projection, institute are provided with the encoder shell end face
The annular projection for being provided with gland and matching with the sealing gasket pedestal profiles is stated, elasticity is set on the sealing gasket base
The sealing gasket that material makes, when the gland and the encoder shell are fastened with the fastener, the sealing gasket base meeting
The sealing that misplaces up and down is formed in the embedded annular projection, the sealing gasket is squeezed by the sealing gasket base and the gland bottom surface
Swaging is into sealing.
Further, the sealing gasket is made up of rubber slab.
Further, sealing gasket positioning convex is provided with the encoder shell end face, be provided with the gland with
The groove that sealing gasket positioning convex matches.
The utility model compares with prior art, and its effect is actively and it will be evident that passing through coding in the utility model
Dislocation sealing up and down is formed in the annular projection that sealing gasket base wedge pressure on device shell covers, effectively protects dust, simultaneously
Sealing gasket is made using rubber or other elastomeric materials, it is produced deformation under the fastening pressure of encoder shell and gland,
Dust and liquid are further protected, there is the advantages of process-cycle is short, and cost is low, and production efficiency is high, product quality is stable, significantly
Encoder is improved in the uniformity and stability used under adverse circumstances operating mode.

Fig. 1 is structure chart of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is the encoder outer casing construction drawing in the utility model.
Fig. 4 is the gland structure figure in the utility model.
Fig. 5 is the gasket structure figure in the utility model.
Embodiment：
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, a kind of shell protection device of encoder, including gland 1, fastener 3, volume
Code device shell 4, it is characterised in that the sealing gasket base 41 of projection, the gland are provided with the encoder shell end face 43
On be provided with the annular projection 11 to match with the sealing gasket pedestal profiles, elastomeric material is set on the sealing gasket base
When the sealing gasket 2 of making, the gland and the encoder shell are fastened with the fastener, the sealing gasket base can be embedded in
Dislocation sealing up and down is formed in the annular projection, effectively protects dust, the sealing gasket is by the sealing gasket base and described
The extruding of gland bottom surface 12 forms sealing, further protects dust and liquid.
Further, as shown in figure 5, the sealing gasket uses quality of rubber materials.
Further, as shown in Figure 3, Figure 4, sealing gasket positioning convex 42 is provided with the encoder shell end face, can
Prevent sealing gasket from shifting in assembling, reduce installation difficulty and improve positioning accuracy and using reliability, set on the gland
It is equipped with the groove 13 to match with sealing gasket positioning convex.
