Description

[Detailed Description of the Invention] The present invention relates to a rotor sheet pasting jig for a rotary piston engine.

Conventionally, in rotary piston engines, a coating layer is provided outside the side seal groove on the side surface of the rotor to reduce the gap between the rotor side surface, the side housing surface, and the side seal as much as possible. Unburned components in gas
It is known to reduce HC and CO.

The present applicant first proposed a method for manufacturing a rotor for a rotary piston engine (particularly in a method for manufacturing a rotor for a rotary piston engine) in which the above-mentioned coating layer can be easily provided on the side surface of the rotor, and as a result, the workability of the rotor can be improved. (See Application No. 55-109442). In other words, the proposed manufacturing method involves preparing a laminated sheet having a heated adhesive layer that cannot be bonded at room temperature but becomes soft and bondable when heated, and inserting the heated adhesive layer of the laminated sheet into the side seal groove on the side surface of the rotor. A coating layer is provided on the side surface of the rotor by bringing the laminated sheet into contact with the outer side and heating and pressing it to soften and bond it, and then further heating and hardening the laminated sheet.

However, when the laminated sheet is disposed outside the side seal groove on the side surface of the rotor, since the width of the laminated sheet is extremely small, it takes time and effort to position the laminated sheet, resulting in poor workability. Additionally, if your hand touches the surface of the heating adhesive layer of the laminated sheet, sweat will adhere to it, resulting in poor adhesion of the heating adhesive layer, making it impossible to reliably adhere the laminated sheet to the side surface of the rotor. There was a problem.

The present invention has been developed in view of the above, and uses a sheet pasting jig when pasting the laminated sheet as described above to the outside of the side seal groove on the side surface of the rotor. By configuring the laminated sheet so that it can be positioned on the side surface of the rotor without touching the surface of the heated adhesive layer of the sheet, the workability of positioning the laminated sheet and the workability of pasting the sheet is improved, and damage caused by adhesion of sweat is reduced. The purpose of this is to prevent a decrease in the adhesiveness of the warm contact layer.

Therefore, the configuration of the present invention is a sheet pasting jig used for pasting laminated sheets, which includes a protrusion provided on the bottom surface of the jig body for positioning to the rotor, and a rotor side surface of the jig body. A slit is drilled at a location corresponding to the location where the laminated sheet is pasted, into which the laminated sheet can fall, and a recess is formed in the outer peripheral portion of the slit on the upper surface of the jig main body so as to be connected to the slit, and the bottom portion extends in the radial direction. a guide recess formed on an uneven surface having uneven stripes and guiding the laminated sheet from the outside to the slit;
The laminated sheet is dropped into the slit through the guide recess and positioned on the side surface of the rotor.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

In FIG. 1, 1 is a rotary piston engine rotor, 2 is an insertion portion formed in the rotor 1 for inserting an eccentric shaft, 3 is a corner seal groove formed on each top side surface of the rotor 1, and 4 is a rotor. This is a side seal groove formed between each of the corner seal grooves 3 and 3 on the side surface of 1. Reference numerals 5, 5, and 5 are arc-shaped laminated sheets with extremely small widths, and each of the laminated sheets 5 is made of a one-component epoxy resin that cannot be bonded at room temperature but softens and becomes bondable when heated. It has a layer (not shown) and is pasted to the outside of the side seal grooves 4, 4, 4 on the side surface of the rotor 1 using the sheet pasting jig 6 according to the present invention.

As shown in FIGS. 2 and 3, the sheet pasting jig 6 has a disk-shaped jig main body 7.
A first protrusion 8 that can fit into the insertion portion 2 of the rotor 1 is protruded from the center of the lower surface of the jig main body 7, and the A second protrusion 9 that can be fitted into the corner seal groove 3 of the rotor 1 is provided in a protruding manner. Therefore, the sheet pasting jig 6 is positioned with respect to the rotor 1.

In addition, the jig main body 7 has a laminated sheet 5,
3 arc-shaped slits 1 into which 5 and 5 can fall
0, 10, 10 are bored, and guide recesses 11, 11, 11 connected to the slits 10, 10, 10 are formed in the outer circumference of the slits 10, 10, 10 on the upper surface of the jig main body 7. has been done. The bottom of each guide recess 11 has a plurality of grooves 1 extending parallel to each other in the radial direction of the jig main body 7.
2, 12... and convex stripes 13, 13,..., and is configured to guide the laminated sheet 5 from the outside to the slit 10. By the above, the laminated sheets 5, 5, 5,
The sheet pasting jig 6 of the present invention is configured such that it is inserted into the slits 10, 10, 10 through the guide recesses 11, 11, 11 of the jig main body 7 and positioned on the side surface of the rotor 1.

Next, the operation of the above embodiment will be explained in accordance with the procedure for attaching the laminated sheets 5, 5, 5 to one side of the rotor 1 on a rotatable rotary table 14 as shown in FIG.

First, the rotor 1 is placed on the rotary table 14 at the loading station 15 (lower position in the figure), and the first sheet applying jig 6 is inserted into the insertion portion 2 and the corner seal groove 3 of the rotor 1, respectively.
Then, the second protrusions 8 and 9 are fitted together to position and place the sheet pasting jig 6 on the rotor 1. After that, the guide recess 1 of the sheet pasting jig 6 is
Laminate sheets 5, 5, 5 are placed on 1, 11, 11 with the heating adhesive layer facing down as shown by the dashed line in FIG. 1, and each laminate sheet 5 is pushed from the outside to guide it. By sliding radially inward on the recess 11 and dropping into the slit 10, each laminated sheet 5 is positioned and arranged on the side surface of the rotor 1.

Here, each laminated sheet 5 can be reliably positioned on the side surface of the rotor 1 by a simple operation of dropping it into the slit 10 through the guide recess 11, thereby simplifying the positioning work of the laminated sheet 5. , its workability can be improved. Moreover, since the bottom of the guide recess 11 is an uneven surface having uneven stripes 12, 12, . . . and 13, 13, . . . extending in the radial direction,
The contact surface between the laminated sheet 5 and the guide recess 11 is small, and the laminated sheet 5 can be slid with a slight force, and the laminated sheet 5 can be easily pushed along the grooved portions 12, 12, . . . Therefore, the laminated sheet 5 can be easily dropped into the slit 10, and the positioning workability can be further improved. Furthermore, when the laminated sheet 5 is sliding, the heated adhesive layer of the laminated sheet 5 is in contact with the surface of the convex strip 13 of the guide recess 11, and the heated adhesive layer is not touched by the worker's hand. Therefore, it is possible to reliably prevent sweat from adhering to the heating adhesive layer, and the adhesive strength of the heating adhesive layer does not deteriorate.

Next, with the sheet pasting jig 6 still placed on the rotor 1, the rotary table 14 is rotated 90 degrees clockwise to attach the rotor 1 to the temporary pasting station 1.

In the tacking station 16, a hot press jig (not shown) of the tacking press device 17 is provided with protruding teeth that can be inserted into each slit 10 of the sheet sticking jig 6. Each laminated sheet 5 is temporarily attached to the side surface of the rotor 1 by heating and pressing a portion of the laminated sheet 5 on the side surface of the rotor 1 through the slit 10 to soften and bond it.

Next, turn the rotary table 14 clockwise 90 degrees.
The rotor 1 is rotated and transferred to the book attachment station 18, but before that, the sheet pasting jig 6 on the rotor 1 is placed between the temporary attachment station 16 and the book attachment station 18. The sheet pasting jig is taken out from the rotor 1 by the sheet pasting jig taking out device 19.

Then, in the book attachment station 18, a hot press jig (not shown) of the book attachment press device 20 heats and presses the entire surface of the laminated sheets 5, 5, 5 temporarily attached on the side surface of the rotor 1, and sufficiently presses the sheets. By softening and adhering each laminated sheet 5 to the rotor 1
A book is attached to the side. At this time, the laminated sheet 5
Since sweat does not adhere to the surface of the heating adhesive layer as described above, the heating adhesive layer adheres well, and the laminated sheet 5 can be reliably attached to the side surface of the rotor 1.

Thereafter, the rotary table 14 is further rotated 90 degrees clockwise to transfer the rotor 1 to the carry-out station 21, and the rotor 1 with the laminated sheet 5 attached thereto is carried out from the rotary table 14 at the carry-out station 21. .

By performing such a procedure on both side surfaces of the rotor 1, a coating layer (not shown) of a predetermined thickness made of the laminated sheet 5 is formed at a predetermined location on both side surfaces of the rotor 1.

In the above embodiment, the insertion portion 2 of the rotor 1 and one corner seal groove 3 are provided on the lower surface of the jig main body 7.
A first protrusion 8 and a second protrusion 9 that can be fitted to the two corner seal grooves 3 and 3 are respectively provided to position the sheet pasting jig 6 to the rotor 1. Of course, a pair of fittable protrusions having the same shape may be provided to position the sheet pasting jig 6.

As explained above, according to the rotor piston engine rotor sheet pasting jig of the present invention, the heating adhesive layer of the laminated sheet can be easily applied by dropping the laminated sheet into the slit through the guide recess. The laminated sheet can be easily and accurately positioned on the side surface of the rotor without reducing the adhesive strength of the rotor.
