Compared with the prior art, the vibration exciter has the advantages that the wiring seat is located at the top of the tubular wall of the motor and close to the eccentric box, so that the amplitude of vibration borne by the wiring seat is greatly reduced, the phenomenon that connections between the wiring seat and cable connectors gets loose to cause short circuit can be avoided, the damage to a controller is avoided, and the wiring reliability of the wiring seat is enhanced; and shown by statistics, the failure ratio caused by the wiring seat can be decreased to 1% from 50%.
Description
Technical field
The utility model relates to the oscillating aging equipment technical field, especially a kind of vibrator with junction block for oscillating aging.
Background technology
Vibrator is one of vitals of vibration ageing device, vibrator commonly used traditionally comprises eccentric case and the permanent magnet DC motor that is provided with junction block that is connected with this bias case, described junction block is contained on the rear end cap of described permanent magnet DC motor, the junction block in described junction block towards with described permanent magnet DC motor axially towards identical.Workpiece being carried out oscillating aging when processing, be that vibrator is fixed on the workpiece that shaken, be connected with cable between the output terminal of the junction block of permanent magnet DC motor and controller, control vibrator by controller workpiece is carried out the processing of subresonance oscillating aging.In to vibrator fault investigation statistics, the fault that is produced by junction block and connected cable adapter is maximum, accounts for 50% of total failare rate; Comprising: 1, in the oscillating aging process, the ease of connection of junction block and cable adapter gets loose, and short circuit even occurs and causes controller to damage; 2, junction block is easily disconnected by shake with the inner wire that is connected; 3, junction block is badly shaken.The reason that above-mentioned phenomenon occurs is: vibrator is the otic placode by the eccentric case two bottom sides of two fixture clampings, be fixed on the workpiece that shaken, the relative bite of permanent magnet DC motor has consisted of a socle girder, the rear end cap of permanent magnet DC motor and the distance of bite are farthest, in the oscillating aging process, the amplitude of junction block vibration is maximum, and therefore, junction block and the wire that is attached thereto can be impaired serious in vibration.
The utility model content
The technical problems to be solved in the utility model is to provide the high vibrator of a kind of junction block wiring reliability.
In order to address the above problem, the technical solution adopted in the utility model is: this vibrator comprises eccentric case and the permanent magnet DC motor that is provided with junction block that is connected with this bias case, described junction block is contained in nearly described eccentric case place, described motor barrel top, described junction block towards with described permanent magnet DC motor axially towards vertical, described junction block is inserted in the junction block cushion block that is fixed in described motor barrel, and the even leading-out terminal of the commutator carbon brush holder leading-out terminal of described permanent magnet DC motor and light passes described motor barrel and is connected with described junction block.
Above-mentioned vibrator, technical scheme can also be more specifically: described junction block is five core aviation junction blocks.
Further, described junction block cushion block is cross-over block.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, because junction block is contained in nearly eccentric case place, motor barrel top, in the oscillating aging process, the amplitude decrease that junction block is vibrated, can avoid occurring junction block and being connected of cable adapter getting loose and the phenomenon of short circuit, avoid controller to damage, strengthen the reliability of junction block wiring; 2, due to the vibrated amplitude of junction block reduces and junction block is vibrated direction and junction block towards identical, also can avoid and commutator carbon brush holder and the even leading-out terminal of light of junction block are shaken phenomenon disconnected and that junction block is badly shaken; Can be reduced to 1% to the failure rate that is produced by junction block from 50% by statistics.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the K of Fig. 1 is to schematic diagram.
Number in the figure explanation: eccentric case 1, junction block cushion block 2, junction block 2-1, motor barrel 3, rear end cap 4.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Vibrator as shown in Figure 1 comprises eccentric case 1 and the permanent magnet DC motor that junction block 2-1 is housed that is connected with this bias case 1, junction block 2-1 is contained in close eccentric case 1 place at motor barrel 3 tops, junction block 2-1 towards with permanent magnet DC motor axially towards vertical, junction block 2-1 is inserted in the junction block cushion block 2 that is fixed in motor barrel 3.The even leading-out terminal of the commutator carbon brush holder leading-out terminal of permanent magnet DC motor and light passes motor barrel 3 and is connected with junction block 2-1, and the commutator carbon brush holder is positioned on rear end cap 4, and 2 leading-out terminals are arranged, and light is even to be fixed on motor barrel 3, and three leading-out terminals are arranged; Junction block 2-1 is five core junction blocks, junction block 2-1 be five core junction blocks be for be connected commutator carbon brush holder leading-out terminal and be connected five leading-out terminals with the light idol and connect, make junction block 2-1 increase reliability.Junction block cushion block 2 is preferably cross-over block, and purpose is to prevent that short trouble from appearring in commutator carbon brush holder and the even leading-out terminal of light and motor barrel 3.Junction block 2-1 is fixedly mounted on the top of motor barrel 3 by being installed on bolt on junction block cushion block 2, as shown in Figure 2.
During work, the terminals of cable are connected between the output terminal of the junction block 2-1 of permanent magnet DC motor and controller, workpiece are carried out oscillating aging process.Be arranged on close eccentric case 1 place at motor barrel 3 tops due to junction block 2-1, compare the amplitude decrease of the suffered direction of junction block 2-1 with the junction block on the existing rear end cap 4 that is arranged on permanent magnet DC motor.In the oscillating aging process, the vibrated direction of junction block 2-1 and junction block 2-1 towards identical, also can avoid junction block 2-1 and being connected of cable terminals to occur getting loose, the phenomenon of short circuit even appears, avoid controller to damage, strengthen the reliability of junction block 2-1 wiring.In addition, due to the vibrated amplitude of junction block 2-1 reduces and junction block 2-1 is vibrated direction and junction block 2-1 towards identical, also can avoid being shaken phenomenon disconnected and that junction block 2-1 is badly shaken with the leading-out terminal that is connected commutator carbon brush holder leading-out terminal and light idol of junction block 2-1; Can be reduced to 1% to the failure rate that is produced by junction block 2-1 from 50% by statistics.
