Description
Technical field
The utility model relates to a kind of encoder fastening means, specifically is the circular copper pipe crimp.
Background technology
The elevator rotary encoder is the device that is used for measuring rotating speed; The photo-electric rotary encoder is through opto-electronic conversion, can convert mechanical quantity such as the angular displacement of output shaft, angular speed to corresponding electric pulse and export with digital quantity; And the output of electric pulse realizes through the encoder cable.
Existing encoder directly is connected with cable through the circular copper pipe on the encoder; Braid in the cable plays the effect of screen layer, and it mainly is to be connected on the copper pipe that is positioned at joint through welding or crimping; If the solder joint rosin joint will cause the bonding strength between encoder and the cable not high; Thereby need adopt the crimping mode; But because the wall thickness of circular copper pipe is less, crimping is easy to generate distortion, can't keep its original circular state, also quality of connection is exerted an influence; Thereby the crimp of a kind of special use of needs.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology; A kind of crimp of novel encoder copper pipe is provided; This crimp should be able to realize that the rotary encoder copper pipe is connected with the reliable of cable, and has simple in structure, easy to assembly and the characteristics that are connected firmly.
The technical scheme that the utility model provides is: the circular copper pipe crimp is characterized in that this circular copper pipe crimp comprises: two be shaped on several gathering sills respectively and can dock the semicircular ring column module of forming annulus column module group, several mate with each gathering sill respectively one by one and the shaping pin that can be in gathering sill radially slides along module and two docks composition annulus sheet slide block group respectively to be used to promote the semicircular ring sheet slide block that said shaping pin moves on the module groups outer circumference surface.
Said several gathering sills are evenly distributed on an axial end of module; Each gathering sill is the fan-shaped post groove that extends along the module radial direction; The cambered surface of fan-shaped post groove runs through the outer circumference surface of module, and two Plane intersects limits of fan-shaped post groove then run through the inner peripheral surface of module through a narrow groove.
The inner peripheral surface of said module is joined by more than half disc and smaller part disc and forms, and said several gathering sills are evenly distributed on the external diameter direction of smaller part disc.
Said each module is shaped on four gathering sills.
Said shaping pin is and the matched fan-shaped post of said gathering sill, and two Plane intersects limits of fan-shaped post are shaped on the pin sheet that stretches along radial direction, the thickness of pin sheet less than said narrow groove length then greater than narrow groove; The fan-shaped radius of whole shaping pin is also greater than the length of the fan-shaped post groove in the gathering sill.
The copper pipe outer circumference surface coupling of the inner peripheral surface of said module and the crimping of circular copper pipe crimp institute.
The beneficial effect of the utility model is: the circular copper pipe crimp that the utility model provided; Mainly used the crimping mode of post forming; Through applying certain pressure on the copper pipe outer circumference surface to institute's crimping; Copper pipe generation deformation but not broken makes to form the braid that multiple spot caves inward and blocks cable on the copper pipe tube wall; Therefore copper pipe is firm with the ten minutes that just becomes being connected of braid; The caducous defective that riveted joint before having solved fully again or welding exist; Avoided having realized that because of receiving the external force effect to cause heart yearn or the impaired situation of attaching parts to take place encoder is connected with the reliable of cable; And this circular copper pipe crimp is simple in structure, easy to use, makes assembling process also very convenient.

The specific embodiment
As shown in the figure, the circular copper pipe crimp comprises the module groups of annulus column, the slide block group and the shaping pin of annulus sheet; Module groups is that module 1 butt joint of two semicircular ring columns is formed; The inner peripheral surface of module 1 is joined by more than half disc 1-2 and smaller part disc 1-1 and forms, and all is used for the crimping copper pipe, its size and copper pipe outer circumference surface coupling; An axial end of each module 1 (the external diameter direction of smaller part disc 1-1) is shaped on four gathering sills 4, and gathering sill 4 is evenly distributed on the axial end of module; Each gathering sill 4 is the fan-shaped post groove that extends along the radial direction of module; The fan-shaped post cambered surface of this groove runs through on the outer circumference surface of module 1, the inner peripheral surface that then runs through module 1 on module 1 two Plane intersects limits on axially through a narrow groove 41 of this groove; The slide block group is that slide block 2 butt joints of two semicircular ring sheets are formed, and each slide block 2 is placed at the outside of module groups outer circumference surface respectively; Because the radius of slide block group is slightly larger than the radius of module groups, so has certain gap between slide block group and the module groups; Shaping pin 3 one has eight, and shaping pin 3 matees with gathering sill 4 one by one, and shaping pin 3 can radially slide along module 1 in gathering sill 4; Shaping pin 3 is and gathering sill 4 matched fan-shaped posts that two Plane intersects limits of its fan-shaped post are shaped on the flat pin sheet 31 that stretches along radial direction; Then greater than narrow groove, the radius of the fan-shaped post in the shaping pin 3 is greater than the length of fan-shaped post groove in the gathering sill 4 less than said narrow groove length for the thickness of pin sheet, and the length of shaping pin 3 is also greater than the length of gathering sill 4; Slide block 2 can promote shaping pin 3 and in gathering sill 4, slide, and the pin sheet on the shaping pin 3 can protrude in the inner headed face of module 1 when sliding.
The operation principle of the utility model is following:
As shown in Figure 9, at first receive encoder circular copper pipe 5 on the cable 6 of appointment, insert this copper pipe in the mould (mould is installed on the forcing press) then; Then starting pressure machine diel extruding slide block 2 up and down, slide block 2 just promote shaping pin 3 and move to copper pipe along gathering sill 4, and the pin sheet on the shaping pin 3 just pushes the circular copper pipe tube wall; The right-hand member 5-2 of circular copper pipe tube wall received external force effect generation deformation and caved inward this moment; And embed in the screen layer 7 of cable (simultaneously; The left end 5-1 of encoder circular copper pipe 5 also receive module 1 more than half disc 1-2 extruding and shrink), circular copper pipe and cable just link together securely (as shown in Figure 9) like this.
