Embodiment
[0018] Embodiment: The hub unit stopper press-fitting method, the method is to set the inner flange of the hub unit on the unit bottom mold above the axially pressurized cylinder, and the action of the pressurized cylinder drives the hub unit to lift. When the blue presses the unit upper mold above the unit bottom mold, the axial pressurization cylinder stops lifting; place the stoppers in the stopper pressing plates on both sides above the unit, and the radial cylinders outside the gear groove extend inward to push the stopper The block is pressed into the block groove of the inner flange to realize the automatic press-fitting of the block. A pressure sensor is set between the block pressing plate and the radial cylinder, and the radial loading force applied by the radial cylinder to the block pressing plate is monitored in real time through the pressure sensor. When the radial loading force exceeds the predetermined range, the radial cylinder sends a signal to control Device...

The invention discloses a hub unit check block press-fitting method and a device thereof. The method includes the steps that an inner flange of a hub unit is arranged on a unit bottom die above an axial pressurizing air cylinder, the pressurizing air cylinder acts to drive the hub unit to ascend, and when an outer flange of the hub unit tightly presses a unit upper die above the unit bottom die, the axial pressurizing air cylinder stops ascending; a check block is placed in check block pressing plates on the two sides of the unit upper die, a radial air cylinder on the outer side of a check groove stretches out inwards, the check block is press-fit in a check block groove of the inner flange, and automatic press-fitting of the check block is achieved. The hub unit check block press-fitting method and the device thereof have the advantages of achieving automatic machining and being high in machining accuracy and good in stability.
Description
technical field [0001] The invention relates to a processing method of a hub unit and a device thereof, in particular to a method for pressing a stopper of the hub unit and a device thereof. Background technique [0002] The third-generation automobile hub unit with "C" type block structure is as attached figure 1 As shown, two "C"-shaped stoppers 109 are press-fitted into the stopper grooves of the inner flange 103 of the automobile hub unit, and the outer end surface of the inner ring 102 is pressed, so that the inner flange 103, the outer flange Parts such as the flange 101, the inner ring 102, and the two rows of steel balls 104 cooperate with each other to form the axial clearance required by the product and ensure the service life of the product. [0003] The press-fitting method of the "C" type stopper of this unit used to use calipers to press the stopper into the stopper groove by manpower. This pressing method is greatly affected by human factors, and it is prone...
