Definitions
- the present invention relates to the preparation of the crankcase of internal combustion engines.
- the present invention relates to a method of cleaning a cylinder cover upper face protection mask which is used in the thermal spraying of coatings inside the engine cylinder drums.
- It also relates to a rotary cleaning apparatus cylinders protective cylinders on the upper side of crankcase used during the thermal spraying of coatings in the engine cylinder drums.
- the protective masks are cleaned to remove the material ("residual oversparay") sprayed on it. They are then stored for reuse.
- masks are cleaned by high-pressure deburring (HP). But the quality of the deburring HP is not constant, and its cycle time is long, because it is necessary to manually resume the cleaning of most masks. These operations generate additional costs. To reduce them, it is necessary to increase the life of the masks, and to reduce their cleaning time.
- the performance objectives in this area are:
- the present invention aims to reduce the cycle time of the cylinder top face protection masks, while ensuring their cleanliness for spraying the following cylinder drums.
- the apparatus also simultaneously performs the cleaning of a circular gutter formed in the mass of the mask near don inner edge.
- This apparatus is composed of a rotated tool holder, which has housings for tools dedicated respectively to the cleaning of the support plane of the mask on the upper face of the crankcase, and the inner edge of the cylindrical mask in support on the crankcase, and for tools dedicated to the cleaning of a circular groove formed in the mass of the mask near its inner edge.
- FIGS. 1A to 1D are views from above, in elevation, in section and in perspective, of a mask
- FIG. 2 shows a mask after use
- FIG. 3 highlights the zones to be cleaned
- FIG. 4 illustrates a first embodiment of a removable head for a tool with wafers or tool brushes, with screw tightening, pads or brushes,
- FIG. 5 illustrates a second embodiment of a removable head, with brush-holder cartridges or toolholders,
- Figures 6 and 7 show the removable heads of Figures 4 and 5 mounted on their tool holder
- Figure 8 shows a removable head in the working position on a protective mask.
- the protective mask of FIGS. 1A to 1D is provided on the upper face of a cylinder block on each cylinder drum opening. Its support plane la, rests around the opening of a barrel of cylinder, to prevent the projection of the product of coating sprayed at high temperature towards the inner surfaces of the barrels, on the upper face of the crankcase, As indicated above, the masks 1 must be cleaned, to remove the residual "overspray" on their underside before they can be reused. Referring to the example of Figure 2 and the enlargement of Figure 3, the areas to be cleaned on the lower face of the mask, are located on its support plane zl, its gutter z2, and its edge interior z3.
- the tool head 2 of Figure 4 is a removable head. It carries three different cleaning tools 3, 4, 6, tight in their center by screws (not shown), which we see the clamping holes 7:
- the three tools 3, 4, 6 of the removable head 2 may be brushes, wafers, or others.
- the head 2 is fixed on a tool holder 8 (such as that of Figures 6 or 7) by a cylindrical shank 10 having for example a flattened area 10a, facilitating its screwing.
- the tool holder 8 of Figure 6 has an attachment end 11 on a rotary drive machine. It carries the removable head 2 of Figure 4, where the tools 3, 4, 6 are screwed directly into housings thereon. In FIG. 7, the tool holder receives the removable cartridge head 2 3a, 4a, 6a of FIG.
- Figure 8 shows a particular embodiment of the invention, with only two brushes, including a first brush 3 to clean the support face of the mask, and a second brush 4, 6, to clean its gutter and its inner edge.
- the tool holder 8 may be devoid of removable head.
- the tools 3, 4, 6, or their mounting cartridges 3a, 4a, 6a are screwed directly onto the tool holder 8.
- the new method of cleaning a cylindrical protective mask of an upper side of the crankcase during the thermal spraying of the engine cylinder barrels is implemented with a rotary apparatus consisting of a door body tool, with or without a detachable head, which has housings for inserting hole tools through their center, or tool cartridges with a hole in their center. These tools may be cutting inserts, brushes, or a combination of both.
- the tool holders may or may not have a removable tool holder head. The tools are screwed directly in their housing on the tool holders or on the removable head, or they are mounted in cartridges, themselves screwed into the housing of the tool holder or the removable head.
- the apparatus simultaneously operates the cleaning of the support plane of the mask on the upper face of the crankcase, and the inner edge of the cylindrical mask resting on the crankcase. It also ensures the cleaning of the circular gutter generally formed in the mass of the mask near its inner edge.
- the platelets have, for example, cutting edges of carbide, ceramic or CBN (cubic boron nitride), with angles to cut the various coating materials projected in the barrels of cylinders.
- the pads are removable, and preferably reversible to increase their life.
- the brushes are also removable. They can be made of nylon, steel or composite materials.
- the reference solution is a three-bladed cleaning device.
- the invention covers other embodiments and their variants, in particular those of the following list:
- a rotary cleaning apparatus with two plates and a brush, for the inner edge or the gutter,
- a rotary cleaning apparatus with a wafer (or brush) for the support surface of the mask, and a common brush for the gutter and the inner edge.
