Description

A kind of new type mining encoder

Technical field

The utility model belongs to the mechanical manufacturing field that colliery industry is related to, and in particular to a kind of new type mining encoder.

Background technique

Encoder (encoder) be signal (such as bit stream) or data are worked out, be converted to can be used to communicate, transmission With the equipment of the signal form of storage.Angular displacement or straight-line displacement are converted into electric signal by encoder, the former is known as code-disc, the latter Referred to as yardstick.Contact and two kinds contactless can be divided into according to playback mode encoder；It can according to working principle encoder It is divided into two class of increment type and absolute type.Incremental encoder is will to be displaced to be converted into periodic electric signal, then this telecommunications Number it is transformed into counting pulse, the size of displacement is indicated with the number of pulse.Each position of absolute type encoder is one corresponding Determining digital code, therefore its indicating value is only related to the starting and ending positions of the measurement, and be independent of the intermediate process of measurement.

Encoder can be divided into according to mechanical erection form:

(1) axonia: axonia can be divided into clamping flange type, synchronous flange-type and servo mount type etc. again.

(2) axle sleeve type: axle sleeve type can be divided into half casement, full casement and heavy caliber type etc. again.

Application percentage of the encoder in the market OEM is higher, is mainly used in that lathe, elevator, servo motor be mating, weaving loom The industries such as tool, package packing machine, printing machinery, hoisting machinery.In addition, encoder is in medical machinery, wind-powered electricity generation, auto production line, mixed Closing the fields such as power vehicle, water conservancy, rail traffic also has certain application, but application percentage is lower.

Encoder is divided into absolute value type and incremental.The price of absolute value encoder is about incremental encoder at present 4 times or more, 70% application is the incremental encoder of price relatively economical on domestic market, is mainly used in as packed, spinning It knits, require nothing more than measurement revolving speed in the industries such as elevator and in Absolute position measurement machinery equipment of less demanding.And in high-precision The heavy industry industry such as mechanical equipment or steel, harbour and lifting, due to relatively high to the required precision of measurement, more situation meetings Use absolute value encoder.In these heavy industry industrial applications, since operating condition is more severe, so the shock resistance to encoder With vibration etc. index requests it is higher.

The mining encoder used under this rugged environment of colliery industry at present, it is a large amount of to use since environment influences Encoder volume it is big, installation is inconvenient.Leakproofness is not fine, and spoilage is high.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of new type mining encoders, solve the prior art In mining encoder volume is big, leakproofness is poor, installation is inconvenient problem.

The utility model uses following technical scheme to solve above-mentioned technical problem:

A kind of new type mining encoder, including encoder cartridge and waterproof matrix, wherein waterproof matrix includes matrix sheet Body, gland and clamp nut, machine core are arranged in matrix bodies, are sealed by gland, and fixed by clamp nut；In gland The heart has axial through-hole, and the through-hole that cable passes through gland is connect with machine core and motor respectively.

It further include the cable guard ring and rubber ring for protecting cable between gland and clamp nut.

Gland has external screw thread close to the side of machine core, for connecting with matrix bodies, has close to the side of clamp nut There is internal screw thread, for connecting with clamp nut.

Matrix bodies have location hole corresponding with machine core, for fixing machine core.

The degree of protection of the mining encoder is IP56.

Compared with prior art, the utility model has the following beneficial effects:

1, generally assembly type, more convenient replacement improve maintenance efficiency.

2, the compatible most domestic machine core of the matrix bodies of the utility model, it is versatile.

3, small in size, simple installation.

4, good airproof performance.

5. large flange disk firmly installs, concentricity is guaranteed.

Detailed description of the invention

Fig. 1 is the Structure explosion diagram of the mining encoder of the utility model.

Wherein, the mark in figure are as follows: 1- matrix bodies；2- machine core；3- gland；4- cable guard ring；5- rubber ring；6- is compressed Nut；7- location hole.

Specific embodiment

The structure of the utility model and the course of work are described further with reference to the accompanying drawing.

Specific embodiment, as shown in Figure 1:

A kind of new type mining encoder, including encoder cartridge 2 and waterproof matrix, wherein waterproof matrix includes matrix sheet Body 1, gland 3 and clamp nut 6, machine core 2 are arranged in matrix bodies 1, are sealed by gland 3, and solid by clamp nut 6 It is fixed；It further include the cable guard ring 4 and rubber ring 5 for protecting cable between gland and clamp nut；

3 center of gland has axial through-hole, and cable one end is connected to motor, and the other end passes through clamp nut 6, cable The through-hole of guard ring 4, rubber ring 5 and gland 3 is connect with machine core 2.

Gland 3 has external screw thread close to the side of machine core 2, for connecting with matrix bodies 1, close to the one of clamp nut 6 Side has internal screw thread, for connecting with clamp nut 6.

Matrix bodies have location hole 7 corresponding with machine core, and for fixing machine core 2, the location hole 7 matching is most on the market Number machine core design, facilitates machine core to install, compatibility is higher.

The degree of protection of the mining encoder is IP56.

The concrete composition and installation method of the utility model encoder are as follows:

The component part of encoder is made of product matrix, machine core, gland, cable guard ring, sealing ring, clamp nut.It produces Product matrix carries mounting disc, successively sequence installing machine core, gland, cable guard ring, sealing ring, clamp nut, and gland effect is Machine core is compressed, secondly cable guard ring, sealing ring, clamp nut effect are that cable is fixed and clamped, and solve cable shaking and make At the raising of machine core damage and sealing performance.

The application principle and application method of the utility model encoder are as follows:

Principle: the mechanical corner of axis is converted to the instrument of digital signal output using the methods of photoelectricity by its machine core.

Encoder is mounted on motor reel end, and a fixed bracket independently installed coding is made on the basis of motor Device, encoder and motor reel center are in same level height, are connected using soft rubber or nylon hose within two weeks, to mitigate Mechanical shock of the motor impact load to encoder；Due to the particularity of colliery industry environment, most of application machinery All in dynamic duty application, situations such as vibration, moist, dust, the utility model is made that improvement for these environment, right Also there is very big lift-off seal formula shell in performance, avoid the impact of foreign object to the damage of product, encoder works middle shaft part in height Speed operating increases ring flange mounting surface, and regular coding device that can be stronger, will not shake because of integral body cause axis to damage It is bad, increase service life.
