Abstract
The utility model provides a novel connection device of an original position switch. The novel connection device is characterized in that the novel connection device comprises a lump adapter which is fixedly connected with a rear end cover of a motor, a back projecting shaft of the motor passes through a shaft through hole arranged in the adapter and is extended out of the adapter, a motor lead wire passes through a lead wire through hole arranged in the adapter and is extended out of the adapter, the back projecting shaft of the motor is fixedly provided with a radially extended baffle piece, and a position of the adapter corresponding to the baffle piece is fixedly provided with a travel switch. According to the novel connection device of an original position switch, the adapter is used to substitute an L shaped bracket, the area of the rear end cover of the motor is reduced, and the range of use of a small motor is enlarged. In addition, the adapter is internally provided with the through hole for the penetration of the motor lead wire, and an intertwined problem of a conducting wire and a motor screw rod is effectively avoided. The device has the advantages of simple structure, ingenious design, and low cost of use.
Description
Technical field
The utility model belongs to a kind of jockey of origin position switch of linear electric motors.
Background technology
Behind the motor of linear electric motors, in the projecting shaft axle rectilinear motion, the induction requirement of origin position is arranged usually.The connected mode of traditional origin position switch is at back end cover for motor the L-type support to be installed, and lays travel switch at the L-type support, obtains the origin position signal by the catch touching travel switch on the motor screw (be provided with the motor of thread segment after projecting shaft).Because the L-type support need to be installed on the motor rear end capping, shared motor rear end capping is larger, use for small machine is just restricted, and the wire of motor rear end need to be fixed on the mounting bracket separately in addition, thereby avoids motor screw at when motion and wire generation wrapping phenomena.
The utility model content
The utility model provides a kind of New junction device of origin position switch, and its purpose solves the shortcoming that prior art exists, and enlarges the motor scope of application, avoids wire and motor screw to twine in simple mode.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of New junction device of origin position switch, it is characterized in that: it comprises a block adapter, adapter is connected in motor rear end and covers, stretch out adapter after the rear projecting shaft of motor passes shaft through-hole set in the adapter, motor down-lead stretches out adapter after passing lead hole set in the adapter; Be installed with radially-protruding catch on the rear projecting shaft of motor, the position of corresponding catch is installed with travel switch on the adapter.
The end of the rear projecting shaft of motor is provided with thread segment, and two nuts are arranged on the thread segment and clamp two catch between the nut, and described catch is set on the thread segment.
Usefulness of the present utility model is:
Use adapter to replace the L-type support, reduced the area that back end cover for motor uses, thereby enlarged the scope of application of small machine.Be provided with in addition through hole power supply machine lead-in wire in adapter inside and pass, thereby effectively avoided wire and motor screw generation winding problem.This apparatus structure is simple, deft design, and use cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model adapter stereogram;
Fig. 2 is the utility model structural representation.
Embodiment
As shown in Figure 1, adapter 1 of the present utility model is block, has a space 10 in it, the middle part of adapter 1 has a shaft through-hole that makes progress 11, adapter 1 is provided with two through hole 13 is installed in the both sides of shaft through-hole 11, also be provided with the lead hole 12 that communicates with space 10 on the adapter 1, also be provided with two travel switch fixing threaded holes 14 on the adapter 1.
As shown in Figure 2, adapter 1 passes to install with two screws 15 and is arranged in the set screw of rear end cap of motor 2 behind the through hole 13 and is connected on the rear end cap of motor 2, the rear projecting shaft 21 of motor 2 stretches out adapter 1 after passing shaft through-hole 11, the end of the rear projecting shaft 21 of motor 2 is provided with thread segment 210, two nuts 3 are arranged on the thread segment 210 and clamp two catch 4 between the nut 3, and catch 4 is set on the thread segment 210 with the through hole of establishing on it.Two screws 16 cooperate with travel switch fixing threaded hole 14 travel switch 5 are installed on the adapter 1, and the position of the travel switch 5 after fixing is corresponding with catch 4.
Motor down-lead 22 stretches out adapter 1 after passing lead hole 12 after through space 10 again.The position of motor down-lead 22 is fixed relatively like this, does not need other fixture just can fix and avoids motor down-lead 22 and the rear projecting shaft 21 of motor 2 to twine.
Claims (2)
1. the New junction device of an origin position switch, it is characterized in that: it comprises a block adapter, adapter is connected in motor rear end and covers, stretch out adapter after the rear projecting shaft of motor passes shaft through-hole set in the adapter, motor down-lead stretches out adapter after passing lead hole set in the adapter; Be installed with radially-protruding catch on the rear projecting shaft of motor, the position of corresponding catch is installed with travel switch on the adapter.
2. the New junction device of a kind of origin position switch as claimed in claim 1, it is characterized in that: the end of the rear projecting shaft of motor is provided with thread segment, two nuts are arranged on the thread segment and clamp two catch between the nut, and described catch is set on the thread segment.
