In addition, the guide portion 23 of installation direction side, also can be formed as at the cup-shaped removing direction opening and replace above-mentioned ring-type.Also can limit the movement of roller trough fixed part 22 to installation direction in this case, play the effect same with male part 22c.
Below, the example of the grinding unit 1 of present embodiment is described.
First, the main part 11 workpiece and medium being put into roller trough 10 is inner, cap 12 is placed in the opening portion 11a of main part 11, and cap 12 is also fixed on main part 11 by cap fixed part 14 by operation calibration plunger 14a.
Then, under the state that pressing projecting part 22d is contained in roller trough fixed part 22 inside, make roller trough fixed part 22 mobile to releasing direction (in Fig. 2 (A) arrow N direction) along guide portion 23.
Next, roller trough 10 is placed in pallet 21, roller trough fixed part 22 is moved along guide portion 23 to the installation direction (the arrow M direction in Fig. 2 (A)) of the fixed position being installed on roller trough 10.At this, owing to being formed with the rake 22f that width narrows towards installation direction M on projecting part 22d, therefore, when making roller trough fixed part 22 move to installation direction, projecting part 22d directed section 23 is pressed into the arrow Y-direction in Fig. 2 (A).And after guide portion 23 is passed through, projecting part 22d gives prominence to again, roller trough fixed part 22 is positioned the position specified.
Then, by fastening bolt 22b, pressing component 22a is declined, cap 12 is pressed to vertical lower and seals after being crimped on main part 11, and roller trough 10 is fixed on roller trough shell 20.
Like this, by pressing component 22a, cap 12 is pressed to vertical lower, and with suitable pressing force, cap 12 is fixed on main part 11, therefore, it is possible to roller trough 10 be fixed on effectively in roller trough shell 20, and without the need to the amount of leaving a blank by roller trough fixed part 22 and cap 12.
In addition, because the contact site 22e of pressing component 22a is corresponding with the outer shape of cap 12, rock therefore, it is possible to prevent pressing component 22a and cap 12 from producing, cap 12 is fixed on main part 11 effectively.
Owing to being fixed on main part 11 by cap 12 with identical pressed state, therefore without the need to the combination of stationary body portion 11 and cap 12, main part 11 just can be become and cap 12 has the grinding unit 1 of interchangeability relative to other caps and main part.
The main part 11 of the roller trough 10 used in present embodiment, to be welded the metallic plate forming side on bending pillared metallic plate by dot welding method and is made.In the past, roller trough main part carried out all-round welding by arc-welding process and was formed, but likely produced melting loss because heat input, and therefore its metallic plate adopts thickness of slab to be the slab of more than 3mm.
On the other hand, as shown in the embodiment, formed the weld part of main part 11 by dot welding method, reduce the possibility of metallic plate melting loss thus, therefore, it is possible to use the metal sheet of about 1mm to make main part 11.Thus roller trough 10 can be made to realize lightweight, alleviate the burden of operator, and the cost making machining period reduction parts can be reduced.And by realizing above-mentioned lightweight, also alleviate the load for making this roller trough 10 carry out the drive source (such as drive motor) of rotation and revolution motion, thus the energy-saving of cylinder lapping device 1 can be realized, and the deterioration of cylinder lapping device 1 can be suppressed.
In roller trough in the past, when changing its liner, be heat forming the rubber of liner and after being removed, form new liner sometimes.But in such replacing options, because the manufacturing cost of the cost and abrasive roller groove 10 that again form liner 13 is equally matched, therefore can not more changeable liner 13 and directly use new roller trough 10.
As mentioned above, manually the roller trough 10 after putting into medium and workpiece is positioned in centrifugal drum lapping device by operator, thus preferably makes it weight reduction.Therefore in the present embodiment, using with resin is matrix, abrasive particle is scattered in the medium that this resin is formed.Weight saving compared with the medium formed by abrasive particle, but if the content of abrasive particle is low just cannot obtain sufficient abrasive power, therefore the content of abrasive particle preferably contains 30 ~ 70 quality % relative to medium, more preferably 40 ~ 60%.In addition, the weight preferably making above-mentioned medium is 0.01g ~ 50g, is more preferably 0.02g ~ 40g, or makes the proportion of above-mentioned medium be 1.6 ~ 2.4, is more preferably 1.8 ~ 2.2.If weight or proportion are less than above-mentioned scope, then the flowing of cylinder in roller trough 10 will become insufficient, cannot obtain sufficient abrasive power, if but weight or proportion are greater than above-mentioned scope, then when grinding due to the collision of workpiece and medium, can produce the surface of workpiece and hit trace.In addition, above-mentioned resin can preferably use: thermoplastic resin (such as nylon resin, polystyrene resin, acrylic resin, polyamide, AS resin etc.), thermosetting resin (such as phenolic resin, unsaturated polyester resin, polyurethane resin, epoxy resin, urea resin etc.).As abrasive particle, known material (such as aluminium, silicon, carborundum, iron oxide, boron oxide, zircon, diamond, diamond dust and their powder or the article shaped etc. being raw material with them) preferably can be used.In addition, the granularity of abrasive particle can be selected aptly according to the object of the proterties of the size of the kind of abrasive particle, medium, workpiece and grinding.
In addition, the shape of above-mentioned medium can consider spherical, post shapes (cylinder, polygon prism), cone shape etc., as shown in Figure 5, be formed as the shape formed by straight metastomium and reducing diameter part, this straight metastomium has circular cross-section and has the identical sectional area of continuous print, this reducing diameter part undergauge continuously from above-mentioned sectional area.There is the abrasive power stronger than spherical medium, and can not as cone shape and post shapes along with grinding carrying out and medium produce uneven wear, same shape can be kept when loss, therefore, it is possible to keep higher abrasive power for a long time.In addition, if when the summit (place that undergauge is maximum) of the edged surface of above-mentioned straight metastomium, above-mentioned straight metastomium and the intersection point of above-mentioned reducing diameter part, above-mentioned reducing diameter part is for acute angle, can be then that basic point produces breakage with acute angle part, becoming is situated between there is the reason of matter crackle, defect, or scuffing or concavo-convex (hitting trace) is produced on workpiece, because being employed herein, the medium after fillet processing is implemented to this acute angle part.Fillet processing both can be processed after formation is with the medium of acute angle part, also just can be formed as not being with acute angle part when forming medium.
The size of above-mentioned medium, can select aptly according to the size etc. of the object of the proterties of workpiece, grinding, roller trough, and preferably, the diameter of above-mentioned circular cross-section is roughly 1 ~ 50mm, is more preferably 2 ~ 40mm.In addition in the medium of above-mentioned shape, preferably make the diameter D of above-mentioned circular cross-section and be 1: 0.5 ~ 1: 1.5 with ratio D: L of the cross-sectional length L of above-mentioned circular cross section orthogonal.If L is too small relative to D, then can not obtaining sufficient abrasive power, if L is excessive, will the uneven wear of medium be produced when grinding.
In addition, using the centrifugal drum lapping device of grinding unit of the present invention, both can be dry-type centrifugal cylinder lapping device, also can be Wet-type centrifugal cylinder lapping device.
