The pallet temporary placing hanger 76L is a member attached vertically upward from the upper surface of the pallet 35, and is a member provided for temporarily placing the assembly 14L after completion of brake contact.
Note that 76R is a member formed symmetrically with 76L.

  FIG. 6 is a view for explaining that the holding means is set in the assembly, and is formed on one surface of the turntable 51 for receiving the pallet 35, the turntable 51 attached to the pallet 35, and the wheel hub 13. In the brake catching device 10 provided with a holding means 53 for holding the workpiece receiving surface 52 and the assembly 14 so as not to be separated from the turntable 51 and for holding the knuckle arm 11 in order to prevent rotation with the turntable 51. It is shown that the knuckle arm 11 of the assembly 14 is set facing upward, and the concave portion 86 of the restraining means 53 is engaged with the work side engaging portion 84 of the knuckle arm 11.

  That is, the restraining means 53 is a member in which the lower member 81 is erected on the pallet 35 and the restraining member 83 is attached to the lower member 81 via the hinge pin 82 so as to be rotatable. The member 83 is engaged with a workpiece side engaging portion 84 that constitutes a part of the knuckle arm 11 on the turntable 51 provided on the pallet 35. As described above, the restraining means 53 has a simple structure including the lower member 81, the hinge pin 82, and the restraining member 83.

  A depression 86 is provided in the holding member 83 so as to engage with the workpiece side engaging portion 84, and the knuckle arm accompanying the rotation of the wheel hub 13 is formed by engaging the workpiece side engaging portion 84 and the depression 86 of the holding member 83. 11 can be prevented.

FIG. 7 is an operation diagram of the restraining means according to the present invention.
In (a), it is shown that the restraining member 83 of the restraining means 53 can be swung as shown by an arrow A to release the restraining of the knuckle arm 11 (see FIG. 6).

  In (b), the restraining of the knuckle arm 11 (see FIG. 6) can be released by removing the hinge pin 82 that connects the lower member 81 and the restraining member 83 and pulling up the restraining member 83 as shown by arrow B. Indicates.

When the work is restrained by the restraining means 53, an operation reverse to the above is performed. That is, in (a), the holding member 83 is moved in the direction opposite to the arrow A. In (b), the holding member 83 is fitted in the direction opposite to the direction of FIG. B, and the hinge pin 82 is inserted into the elongated hole 85 formed in the lower member 81. In any of the methods (a) and (b), the knuckle arm 11 can be reliably suppressed by a simple operation.
Therefore, it is possible to easily perform the operation of suppressing the knuckle arm 11.

FIG. 8 is an operation diagram of the brake contact device according to the assembly setting, and shows that the assembly 14 is set on the work receiving surface 52 of the turntable 51 with the bolt 54 of the wheel hub 13 facing downward. Since the bolt hole 55 into which the bolt 54 of the wheel hub 13 is inserted is provided in the workpiece receiving surface 52 of the turntable 51 and the assembly (workpiece) 14 is positioned so as not to rotate, the bolt 54 of the wheel hub 13 is inserted into the bolt hole 55. The wheel hub 13 can be set on the turntable 51 simply by inserting it.
That is, the wearing time can be shortened while having a simple structure.

Returning to FIG. 2, it shows that the assembly member 14 set on the turntable 51 is set by hanging the holding member 83.
Since the pallet 35 is provided with the receiving surface 13 of the wheel hub 13 and the restraining means 53 for preventing the accompanying rotation on the knuckle arm 11 side, the restraining work of the knuckle arm 11 can be easily performed.

The convex fitting portion 67 of the rotation input member 34 is fitted to the turntable 51 on the pallet side, and the pressing piece 49 is connected to the knuckle arm from above. 11 descends to the center of the arm 11 and presses the knuckle arm 11. Then, the rotation input member 34 is rotated, the wheel hub 13 is rotated with respect to the knuckle arm 11 for a predetermined time, and the brake is hit.
Since the rotation input member 34 that can be connected to the input means from the table rotation means 16 that is an external rotation means is provided, an elevation unit for raising and lowering the turntable 51 is not necessary.

  In addition, the pallet is provided with a turntable 51 rotatably attached to the pallet 35, a table rotating means 16 for turning the turntable 51, and a restraining means 53 for preventing the assembly 14 and the turntable 51 from being rotated. Once the assembly 14 is set on 35, the brake contact of the assembly 14 can be achieved only by moving the pallet 35 and positioning the pallet 35. Furthermore, the work positioning work etc. after the brake contact is unnecessary.

That is, a dedicated conveying device for carrying a workpiece into the device or carrying the workpiece out of the device is not necessary, and can be constituted only by a conveyor and a pallet.
Therefore, the apparatus including the restraining means 53 such as a rotation stopper can be made a simple structure.
As a result, the device can be kept at a low cost.

  Furthermore, since the turntable 51 is rotatably attached to the pallet 35, the wheel hub 13 can be set on the turntable 51 side, and the knuckle arm 11 can be set on the upper side. Since the knuckle arm 11 can be set on the upper side, it is not necessary to change the assembly 14 accompanying reversal during the take-out operation, and workability is improved.

Another embodiment according to the present invention will be described below.
FIG. 10 is a view for explaining another embodiment according to the present invention.
