Description

A kind of scrambler

Technical field

The utility model relates to the scrambler field of rotating for controlling servomotor, refers to a kind of scrambler especially.

Background technology

Scrambler on servomotor is the equipment carrying out signal or data to work out, be converted to the signal form of transmission and storage, part in scrambler and the precision of assembling serve very important effect to scrambler, nowadays most coder structure is more complicated, precision is not ideal enough, well can not ensure right alignment when axle is connected with scrambler and concentricity when scrambler is connected with servomotor; The connection of the axle of scrambler and servomotor is also simple not simultaneously.

Cause the reason of the problems referred to above to mainly contain 3 points: 1, encoder element is too much, assembling is complicated, is unfavorable for producing; 2, bearing accuracy is inadequate, or only adopts single plain bearing; 3, scrambler is when being connected with motor, connects insecure, or assembling is complicated.

Utility model content

Utility model proposes a kind of scrambler, solves unfavorable production in prior art, and precision is inadequate, structure problem loosely.

The technical solution of the utility model is achieved in that

A kind of scrambler, comprise main part, bearing portions and parts part, described main body is that one-step casting is shaping, described bearing portions is through main part center, the bearing that described bearing portions comprises the axle sleeve for being connected with the axle of servomotor and is placed on outside axle sleeve, scribbles sealing anaerbic adhesive at contact position and axle sleeve with the position contacted during bearing assemble when described main part is assembled with bearing portions.

As preferably, described bearing portions also comprises retaining ring, and described retaining ring to be assemblied on sleeve and to carry out fastening with stud bolt and fluid sealant to both contacts site.

As preferably, described parts part comprises code-disc and snap ring, and described code-disc is positioned on axle sleeve step, and described code-disc and axle sleeve are fixed by snap ring.

As preferably, described bearing is two and is placed on high-accuracy V-type bearing on axle sleeve side by side to ensure the concentricity of scrambler and motor shaft.

As preferably, described parts part also comprises pcb board, optical signal detecting element, quiet grating and light-emitting component.

As preferably, described pcb board is secured by bolts in the upper end of main body, installs optical signal detecting element below described pcb board.

As preferably, described quiet grating to be fixed in main body and adjacent with code-disc.

As preferably, described quiet grating side has through hole, is positioned at below base in the through hole that described light-emitting component is installed on quiet grating.

As preferably, described scrambler is connected by scrambler shell fragment and bolt with motor.

Beneficial effect

Technical problem to be solved in the utility model is that the structure of scrambler is simple, and high precision, saves production cost, can high temperature resistant and long service life, and structural stability is high, and manufacture craft is simple, low price during manufacture.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is planar structure schematic diagram of the present utility model;

Fig. 3 is the diagrammatic cross-section of A-A section in Fig. 2.

In figure, pcb board 1, signal detection component 2, code-disc 3, quiet grating 4, main body 5, light-emitting component 6, retaining ring 7, snap ring 8, bearing 9, bearing 10, axle sleeve 11, scrambler shell fragment 12.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 3, the inside of scrambler consists of: pcb board 1; Be fixed on the optical signal detecting element 2 below pcb board; Be positioned over the code-disc 3 on axle sleeve step; Be fixed on quiet grating 4 adjacent with code-disc in main body; The encoder main body 5 that one-step casting is shaping because main body 5 to be one-step castings shaping, thus fundamentally ensure that the simple of coder structure and stability; Main body is assembled quiet grating 4 side devise a through hole and be used for placing light-emitting component 6, make it have good stability, can not come off or the bad phenomenon such as double swerve; To the retaining ring 7 that axle sleeve and axle are locked, need carry out fastening to both contacts site with stud bolt and fluid sealant when retaining ring 7 is assembled on axle sleeve 11; Be used for fixing the snap ring 8 of code-disc; High-accuracy V-type bearing 9 and high-accuracy V-type bearing 10, when running in bearings, fluid sealant must be coated with the position contacted during bearing assemble and axle sleeve with the position contacted during bearing assemble in main body, guarantee that junction can not loosen, adopt high-accuracy V-type bearing effectively to ensure that the concentricity of scrambler and motor shaft; Run through the axle sleeve 11 (being used for being connected with the axle of servomotor) of encoder main body 5; Connect the scrambler shell fragment 12 of scrambler and motor.

As shown in Figure 1, uncomplicated for ensureing main body, structure is simple, high precision, and the main body of scrambler of the present utility model adopts one-step casting shaping, can be simple in the structure being fundamentally scrambler, and design is more reasonable, improves the stability of product structure.
