Abstract
The invention discloses an automatic nut skirt locking and riveting machine which is used for carrying out locking/riveting and looseness prevention on a large-torque skirt nut of an axle assembly. The automatic nut skirt locking and riveting machine is characterized in that a piston rod of a gas-liquid pressurizing mechanism is connected with a pull rod; the pull rod is provided with a pull pin rod; the pull pin rod penetrates in a sliding groove in a locking and riveting tool bit; a certain angle is formed between the axial line of the sliding groove and the axial line of the pull rod; the nut is located in a locating device. According to the automatic nut skirt locking and riveting machine disclosed by the invention, a tensile force generated by the gas-liquid pressurizing mechanism acts on the pull rod, so that the locking and riveting tool bit is enabled to move around the pull pin rod, a nut skirt is enabled to be subjected to plastic deformation through automatic pressurizing, and the function of locking and riveting the nut is realized; a detection element is triggered through a detection rod, so that the deformation of a locking and riveting point of the nut skirt by the locking and riveting tool bit can be controlled; the deformation of the locking and riveting point can be accurately controlled, and the phenomenon that the locking and riveting point of the nut skirt is fractured due to the increment of the deformation can be effectively avoided, and the phenomenon of unreliable locking and fixing of the nut due to insufficient deformation of the locking and riveting point is also avoided, so that an ideal locking and riveting effect of the nut skirt at the locking and riveting point is achieved, the fastening and looseness prevention functions of the locking and riveting point on the nut is ensured, and the manufacturing cost is low.
Description
Technical field
The present invention relates to machinery manufacturing technology field, specifically a kind of device for carrying out automatic locking riveting to the shirt rim of shirt rim nut.
Background technology
It is fastening that the counterpart of automotive axle assembly adopts screw bolt and nut to carry out mostly.But in car load runs, getting loose of bolt and nut is not easily found in time, and the phenomenon that caused vehicle can not normally travel is commonplace, brings larger economic loss and negative social influence to automotive axle producer.
At present, the nut anti-looseness of automotive axle assembly generally adopts spring shim, is coated with the mode of fastening glue, but; for the nut of high pulling torque; except have employed the locking measure of painting fastening glue, usually also to carry out the riveting of distortion lock to the shirt rim of nut, to improve the de-reliability of high pulling torque nut anti-looseness.But, due to the reasons in structure of nut shirt rim, be all adopt the mode of manually rushing riveting usually, lock riveting is carried out to the shirt rim of nut.This operating type, effectively can not ensure the uniformity of locking the distortion of nut shirt rim, riveting position, and even in the process of lock riveting, because manual operation is firmly uneven, ftracture in partial nut shirt rim, causes lock riveting point cannot reach due anti-loosing effect.
Summary of the invention
For solving the artificial deficiency to nut lock riveting in prior art, goal of the invention of the present invention is to provide a kind of nut shirt rim automatic locking riveter, adopt nut shirt rim lock riveting point Self-pressurizing agri, it is made to produce plastic deformation, and the deflection of lock riveting point is controlled by detecting element, thus make the lock riveting effect that the nut shirt rim of lock riveting point reaches desirable, to ensure the quality bills of materials of axle assembly, reduce production cost.
For achieving the above object, the piston rod of gas-liquid pressure-boosting mechanism of the present invention is connected with pull bar, with drawing pin rod on pull bar, draws pin rod to penetrate in the chute of lock riveting cutter head, the axis of chute becomes the angle of 18 degree to 20 degree with the axis of pull bar, and nut is positioned in positioner.
Under the oil cylinder of described gas-liquid pressure-boosting mechanism, adpting flange is connected with the main body base plate of main body, and automatically controlled button is contained on the annular hand grip of main body.
Described just positioning sleeve band porose one and hole two, be positioned at the beginning of the middle part seamed edge of nut in hole one, and the outer round surface of the Kong Eryu main body of first positioning sleeve coordinates to be installed; Detachable location-plate is connected with the lower end installing hole of main body (14), positioning reed inserts in the groove of location-plate, be screwed, positioning reed falls into in the keyway of the spindle nose of nut screw connection, the shirt rim, top of nut is accurately positioned in the endoporus of location-plate, and the lock riveting point of location-plate to nut is accurately located.
Described main body is equipped with the feeler for controlling the nut lock riveting point lock riveting degree of depth and detection trigger element, detecting element is proximity sensor.
The pulling force that the hydraulic cylinder of gas-liquid pressure-boosting mechanism of the present invention produces acts on pull bar, and lock riveting cutter head is moved around drawing pin rod, and Self-pressurizing agri makes nut shirt rim produce plastic deformation, realizes the lock riveting function to nut; And by feeler detection trigger element, control the deflection of lock riveting cutter head to nut shirt rim lock riveting point.
The present invention compared with prior art, has the following advantages:
1, the present invention accurately can control the deflection locking riveting point, effectively can avoid the increase because of deflection, cause the phenomenon that nut shirt rim lock riveting point breaks, it also avoid because of lock riveting point deformation quantity not sufficient, nut is caused to lock insecure phenomenon, thus the lock riveting effect making the nut shirt rim of lock riveting point reach desirable, ensure that lock riveting point is to fastening nuts locking functions.
2, each lock riveting point can be made relatively to lock the position of riveting groove accurately, make the deflection of nut shirt rim lock riveting consistent.
3, can the effectively workmanship of lifting car axle assembly and the competitiveness of product, reduce manufacturing cost.
