In order to improve the hardness of motor shaft, quench treatment need to be carried out in the one end with centre hole on motor shaft.Due to a variety of causes, motor shaft there will be inversion in being delivered to the process of quenching device, has one end of centre hole and does not have an extreme direction of centre hole to put back.Because the two ends of motor shaft do not have centre hole except one end has the centre hole the other end, other profiles are substantially the same, therefore in motor shaft quenching process, be difficult to find inverted motor shaft, part motor shaft has one end of centre hole just likely not carry out quench treatment, therefore one end that this motor shaft has a centre hole does not just reach hardness requirement, so just likely motor shaft and being connected of other mechanisms are impacted, and then affect the quality of whole automobile steering system.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of can prevent that inverted error prevention means occurs motor shaft thermal treatment end in quenching process.
For achieving the above object and other relevant objects, the utility model provides a kind of motor shaft thermal treatment end error prevention means, comprise a motor shaft, one end of described motor shaft is provided with centre hole, described motor shaft is between the first baffle plate and second baffle, one end of described motor shaft is resisted against on the first baffle plate, described second baffle is provided with a cylinder, the piston rod of described cylinder is provided with a magnet ring, one side of described cylinder is provided with a Hall element for detection of described cylinder piston rod miles of relative movement, and described Hall element, cylinder are all connected with a controller.
Preferably, the free end of the piston rod of described cylinder is provided with a pressure transmitter and connects, described pressure transmitter is corresponding with the central position of described motor shaft, and the diameter of described pressure transmitter is less than the diameter of described centre hole, and described pressure transmitter is connected with described controller.
Preferably, described controller is also connected with a warning device.
Preferably, described controller is PLC controller or singlechip controller.
As mentioned above, motor shaft thermal treatment end error prevention means of the present utility model has following beneficial effect: this motor shaft thermal treatment end error prevention means arranges magnet ring on the piston rod of cylinder, a side at cylinder arranges Hall element, this error prevention means in use, motor shaft is placed between two baffle plates, then make the piston rod of cylinder protruding, if motor shaft has one end of centre hole near being positioned at second baffle, the piston rod of cylinder can just extend in this centre hole, the distance that piston rod stretches out is longer, if motor shaft does not have one end of centre hole near second baffle, the piston rod of cylinder can withstand on the end face of motor shaft, the outwardly directed distance of piston rod is shorter, therefore by Hall element, determine that the distance that cylinder piston rod stretches out just can judge whether motor shaft is inverted, can solve motor shaft thermal treatment and bring out wrong problem.

Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification sheets.
Refer to Fig. 1.Notice, appended graphic the illustrated structure of this specification sheets, ratio, size etc., equal contents in order to coordinate specification sheets to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification sheets, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of motor shaft thermal treatment end error prevention means, and this error prevention means comprises a motor shaft 1, in one end of motor shaft 1, is provided with centre hole 2.Motor shaft 1 is between the first baffle plate 3 and second baffle 4, and one end of motor shaft 1 should be resisted against on the first baffle plate 3.On second baffle 4, be provided with a cylinder 5, the piston rod 6 of cylinder 5 is provided with a magnet ring 7, a side at cylinder 5 is also provided with a Hall element 8, Hall element 8 is for detection of the miles of relative movement of piston rod 6, Hall element 8, cylinder 5 are all connected with a controller, and controller is used for controlling cylinder 5 actions.Controller can be selected PLC controller or singlechip controller.
This error prevention means in use, motor shaft 1 is placed between two baffle plates 3,4, then make the piston rod 6 of cylinder 5 protruding, if motor shaft has one end of centre hole 2 near being positioned at second baffle 4, the piston rod 6 of cylinder just can just extend in this centre hole, so the distance that piston rod stretches out is longer; If motor shaft 1 does not have one end of centre hole near second baffle 4, the piston rod of cylinder can withstand on the end face of motor shaft 1, and the outwardly directed distance of piston rod 6 is shorter.By Hall element 8, determine that the distance that cylinder piston rod 6 stretches out just can judge whether motor shaft is inverted, and so just can play and prevent that motor shaft thermal treatment from bringing out wrong problem.For the ease of identification, controller can be connected with the recognition lights of different colours, as green light represents motor shaft, is not inverted, and when red represents motor shaft inversion.
In order to prevent that piston rod 6 immediate roofs of cylinder 5 from damaging on the end face of motor shaft 1, a pressure transmitter 9 can be set at the free end of piston rod 6, pressure transmitter 9 should be fixed on the outer face of piston rod 6, and pressure transmitter 9 is connected with controller.When the piston rod 6 of cylinder 5 withstands on the outer face of motor shaft, pressure transmitter 9 sends and feeds back signal to controller like this, and controller makes cylinder 5 stop action, so just can effectively protect cylinder, the work-ing life of prolongation cylinder 5.With Time Controller, can also be connected with warning device, to remind operator to note.
This motor shaft thermal treatment end error prevention means determines that by Hall element the distance that cylinder piston rod stretches out just can judge that whether motor shaft is inverted, and can solve motor shaft thermal treatment and bring out wrong problem.This motor shaft thermal treatment end error prevention means not only can judge whether motor shaft is inverted, can also judge whether the depth of center hole on motor shaft meets specified requirement, therefore adopt this motor shaft thermal treatment end error prevention means to detect the quality that motor shaft can effectively improve motor shaft.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
