Abstract

The invention provides a novel structural encoder which comprises a rotating shaft, a shaft sleeve, a locating seat, a locating shell, a snap ring, a rotating plate, a locking plate, electric brushes and an electric brush outer shell. Shaft sleeve locating grooves which are evenly distributed and a locking point which is close to the lateral side of the shaft sleeve in an attached mode are arranged inside the shaft sleeve. A locking block is arranged on the locking plate. The locating seat is of a cylindrical shape which can be embedded inside the locating shell. The outer surface of the locating shell is tightly attached to the shaft sleeve locating grooves in the inner surface of the shaft sleeve. Two notches which are oppositely arranged and used for containing locating pillars are formed in the outer edge, perpendicular to the direction of the rotating shaft, of the locating seat. A through hole is formed in the center of the locating seat. The rotating shaft can be inserted into the through hole. Due to use of the locating pillars with positions changeable, the novel structural encoder can be applied in high-temperature welding environment of reflow welding. The locking plate is made of stainless steel, due to the fact that the locking plate is high in rigidity and uneasy to deform, locking bearing force can be improved, and the service life of the locking plate is prolonged. Due to the fact that the electric brush outer shell covers the electric brushes in a molding mode, swing arms of the electric brushes can not loosen in high-temperature environment, and contact of the electric brushes and the rotating plate is stable.

Description

The new structure scrambler

Technical field

The present invention relates to the electronic devices and components field, particularly a kind of new-type coder structure.

Background technology

In traditional scrambler, it generally adopts the kirsite stop-motion seat in conjunction with the structure of plastic cement stop point, but along with the increase of service time, plastic cement stop point is because hardness is low, the stop holding capacity is less, is easy to generate distortion, and product does not reach its required performance for a long time.

Simultaneously, CC sheet riveting is in kirsite stop seat, riveting is in rotating shaft again, it is cooperated with spacer form the anchor point structure, for structure herein, because the kirsite stop-motion seat produces distortion at riveting point behind high temperature, rotation anchor point feel is changed, thereby can not be applied to the Reflow Soldering welding surroundings.

Moreover, brush and plastic cement body adopt the mode of riveting point riveted, and this structure is also because owing to use plastic cement body riveted brush, plastic cement riveting point can be out of shape and cause brush loosening when high temperature, form loose contact, thereby be not suitable for being applied in the environment of Reflow Soldering welding.

Summary of the invention

Technical matters to be solved by this invention is: provide a kind of and can be applied to the Reflow Soldering welding surroundings under hot environment, anti abrasive coder structure, make the life-span at each position can continue longer.

The technical solution adopted for the present invention to solve the technical problems is:

The new structure scrambler comprises rotating shaft, axle sleeve, positioning seat, location shell, snap ring, rotating disk, locking plate, brush and brush shell.Described axle sleeve inside is provided with the stopper point that equally distributed axle sleeve locating slot and is pressed close to the axle sleeve side, and described locking plate has a stop block; Described positioning seat is for embedding the post shapes of shell inside, location, the outside surface of location shell is close to the axle sleeve locating slot of axle sleeve inside surface, two breach that hold reference column that are oppositely arranged are arranged in the positioning seat outer perpendicular to rotor shaft direction, reference column is put into the edge, outer that the breach rear surface protrudes from positioning seat, and the center of described positioning seat is for can insert the through hole of rotating shaft.

Preferably, the thickness of described locking plate is identical with the thickness of place, stopper point face, and locking plate is the stainless steel locking plate.

Further, described snap ring embeds one and moulds in the shell catch, moulds the shell catch and is fixed between described axle sleeve and the brush shell.

The swing arm of described brush is coated among the described brush shell.

Preferably, outside surface and the inside surface of location shell are the locating slot corresponding with described axle sleeve locating slot shape; Be provided with an arc spring lamination between the inside surface of positioning seat and location shell.Wherein, arc spring lamination and location shell are stainless steel.

The invention has the beneficial effects as follows: increase a surfaces externally and internally all with the location shell of the locating slot of waveform, to locate shell is pressed in the axle sleeve, because the axle sleeve inboard also has corresponding axle sleeve locating slot, during the rotating shaft rotation, by the slip of reference column corresponding to the waveform locating slot, namely form the anchor point structure, because arc spring lamination, location shell all adopt stainless steel, use this material can be applied to the high-temperature soldering environment of Reflow Soldering, simultaneously be difficult for taking place qualitative change and wearing and tearing in the rotation process, greatly leap ahead serviceable life; And locking plate uses stainless steel, because locking plate hardness height is not yielding, can improve the backstop holding capacity, and strengthened its serviceable life; Brush is plastic among the brush shell, can make under the hot environment, and the swing arm of brush can not produce loosening, contacts more stable with rotating disk.

Embodiment

As shown in Figure 1, the described new structure scrambler of present embodiment comprises rotating shaft 1, axle sleeve 2, positioning seat 3, snap ring 4, rotating disk 5, locking plate 6, brush 7, brush shell 8 and location shell 9.Described axle sleeve 2 inside are provided with the stopper point 22 that equally distributed axle sleeve locating slot 21 and is pressed close to the axle sleeve side, and described locking plate 6 has a stop block 61; Described positioning seat 3 is for embedding the post shapes of shell 9 inside, location, with reference to Fig. 3, the outside surface of location shell 9 is close to the axle sleeve locating slot 21 of axle sleeve inside surface, two breach that hold reference column 31 that are oppositely arranged are arranged in the positioning seat outer perpendicular to rotor shaft direction, reference column 33 is put into the edge, outer that the breach rear surface protrudes from positioning seat, and the center of described positioning seat is for can insert the through hole 32 of rotating shaft.

Further, described snap ring 4 embeds one and moulds in the shell catch 10, moulds shell catch 10 and is fixed between described axle sleeve 2 and the brush shell 8.

As shown in Figure 2, locking plate 6 is preferably the stainless steel locking plate, the thickness of described locking plate is identical with the thickness of place, stopper point face, locking plate can be concordant with the plane, place, stopper point of axle sleeve inside with this, use material more hard simultaneously, can prevent stop block 61 distortion that too much make locking plate because using.

As shown in Figure 3, outside surface and the inside surface of location shell 9 are the locating slot 91 corresponding with described axle sleeve locating slot shape; Be provided with an arc spring lamination 11 between the inside surface of positioning seat 3 and location shell 9.Wherein, arc spring lamination 11 and location shell 9 are stainless steel.

With reference to Fig. 4, the swing arm 71 of described brush 7 is coated among the described brush shell 8.Because swing arm is plastic among the brush shell, can make it under the environment of high temperature, the swing arm of brush still can not produce loosening, contacts more stable with rotating disk.
