When making calibration plunger 14a when the O of Fig. 2 direction is rotated,, therefore can cap 12 be taken off from main part 11 owing to be disengaged with respect to pushing of cap 12.
So; Roller trough 10 has cap 12 is fixed on the cap fixed part 14 on the main part 11; Can simply and effectively fix, therefore need not consider the matching of main part 11 and cap 12, can make main part 11 and cap 12 have interchangeability with respect to other caps and main part.
At this, the position and the quantity of cap fixed part 14 is set, can set according to the suitable size ground of roller trough 10.
As shown in Figure 2, roller trough shell 20 comprises: pallet 21, and put its year and keep roller trough 10; Roller trough fixed part 22, it is fixed in pallet 21 with roller trough 10; A pair of guide portion 23 is used for when dismounting roller trough 10, moves but guide roller groove fixed part 22 makes it along continuous straight runs (being the rotating shaft direction) in this embodiment.Roller trough shell 20 is installed on the turntable (revolution disk) of not shown centrifugal drum device, can carry out rotation via rotating shaft 24.
Roller trough fixed part 22 comprises: to the pressing component 22a that roller trough 10 is pushed, it lies across and is configured in the position relative with pallet 21, can roller trough 10 be pushed to vertical lower; As the male part 22c and the projecting part 22d of positioning element, be used for when mounting cylinder groove fixed part 22, be moving of benchmark restriction roller trough fixed part 22 with guide portion 23.
Projecting part 22d forms tabular in this embodiment, constitutes the inside that can be contained in roller trough fixed part 22, by spring etc. to outstanding laterally direction (the arrow directions X Fig. 2 (the A)) application of force from the inside of roller trough fixed part 22.
Projecting part 22d forms: outstanding when mounting cylinder groove fixed part 22, restriction roller trough fixed part 22 moves to removing direction (the arrow N direction among Fig. 2 (A)).
When removing roller trough fixed part 22, resistant function power is contained in the inside of roller trough fixed part 22 with projecting part 22d, thereby can remove mobile restriction simply, moves it.
In addition, the guide portion 23 of installation direction one side also can form at the cup-shaped of removing the direction opening and replaces above-mentioned ring-type.Also can limit roller trough fixed part 22 in this case to the moving of installation direction, play the effect same with male part 22c.
Below, the use-case that makes of the grinding unit 1 of this embodiment is described.
At first, workpiece and medium are put into main part 11 inside of roller trough 10, cap was placed the peristome 11a of main part 11 in 12 years, operation calibration plunger 14a also is fixed in main part 11 through cap fixed part 14 with cap 12.
Then, it is contained under the inner state of roller trough fixed part 22 pushing projecting part 22d, makes roller trough fixed part 22 mobile to removing direction (arrow N direction in Fig. 2 (A)) along guide portion 23.
Next, roller trough was placed pallet 21 in 10 years, roller trough fixed part 22 is moved along guide portion 23 to the installation direction (the arrow M direction among Fig. 2 (A)) of the fixed position that is installed on roller trough 10.At this, owing on projecting part 22d, be formed with the rake 22f that width narrows down towards installation direction M, therefore when making roller trough fixed part 22 when installation direction moves, the arrow Y direction of projecting part 22d directed section 23 in Fig. 2 (A) is pressed into.And after guide portion 23 was passed through, projecting part 22d was outstanding once more, the position that roller trough fixed part 22 is positioned to stipulate.
Then, pressing component 22a is descended, cap 12 is sealed after main part 11 is pushed and be crimped on to vertical lower, and roller trough 10 is fixed in roller trough shell 20 through fastening bolt 22b.
Like this; Through pressing component 22a cap 12 is pushed to vertical lower; And cap 12 is fixed in main part 11 with appropriate pressing force, therefore can roller trough 10 be fixed in the roller trough shell 20 effectively, and need not the amount of leaving a blank by roller trough fixed part 22 and cap 12.
In addition,, can prevent that therefore pressing component 22a and cap 12 generations from rocking, cap 12 is fixed on the main part 11 effectively because the contact site 22e of pressing component 22a is corresponding with the outer shape of cap 12.
Owing to can cap 12 be fixed on the main part 11 with identical pressed state, therefore need not the combination of stationary body portion 11 and cap 12, just can become main part 11 and cap 12 have interchangeability with respect to other caps and main part grinding unit 1.
The main part 11 of the roller trough of using in this embodiment 10 is through dot welding method the metallic plate that on the pillared metallic plate of bending, forms the side to be welded to make.In the past, the roller trough main part carried out welding in week entirely forming through arc-welding process, but might produce melting losses because of the heat input more, so its metallic plate employing thickness of slab is the above slab of 3mm.
