Abstract

PURPOSE:To form a bearing simply with good workability and smoothen the lower surface of the bearing, by a method wherein the rims of the recessed groove of a thermoplastic member is bent onto a rotary shaft while fusing them by an ultrasonic wave generating unit, whereby the bearing is formed. CONSTITUTION:A rotary shaft 32 is fitted into a recessed groove 36 and, thereafter, the ultrasonic wave generating unit 37 of an ultrasonic fusion welding machine is pushed against the vicinity of the rims of the recessed groove 36. The lower surface 38 of the ultrasonic wave generating unit is recessed so as to have a circular curvature and both tip ends 30, 39 thereof are pushed against the vicinity of the rims. When the ultrasonic wave generating unit 37 is pushed down while generating ultrasonic waves from the ultrasonic wave generating unit 37, the rims are cut by fusing and are bent inwardly by the lower surface 38 of the generating unit. When the ultrasonic wave generating unit 37 is pushed down further, the rims are cut further by fusing and are bent on the rotary shaft 32, whereby a bearing 40 may be formed. The lower surface 42 of the bearing, with which the rotary shaft 32 contacts slidingly, is smoothed; therefore, the rotary shaft 32 may be rotated smoothly.

0 ((, if this was too large, there was a problem that the rotating shaft 50 would easily come off. Also, as shown in the same figure (b), the rotating shaft 50 is fitted between the members 54 and 55. Although this method is known, it is troublesome that the members 54 and 55 must be fixed by welding means, bolt means, etc. Also, as shown in FIG. A known method is to bend the end of the rotating shaft 50 after inserting the rotating shaft 50 into the section 57.
Since it is necessary to bend the wire after inserting the wire into the hole 57, there is a problem in that the work efficiency is not improved. Furthermore, as shown in FIG. 5(d), the recess 59 of the thermoplastic member 58
A conceivable method is to heat and deform the edge of the groove 59 after inserting the rotating shaft 50 into the groove 59 to provide a projection 60, 60 for preventing removal. However, it is difficult to set the heating temperature for this device, and if the temperature is low, it is difficult to deform, and if the temperature is high, the thermoplastic member 58 is likely to melt and weld to the rotating shaft 50. Furthermore, the lower surfaces 61 of the protrusions 60, 60 on which the rotating shaft 50 comes into sliding contact are not smooth surfaces, which impede smooth rotation of the rotating shaft 50, and there are also problems in appearance, such as irregularities and hard to see. .

A bearing is formed by bending the edge of the recessed groove onto the rotating shaft while cutting the vicinity of the edge by the tip. According to this method, the bearing can be easily formed with good workability, and the inner surface of the bearing on which the rotating shaft slides can be formed into a smooth surface that does not inhibit the rotation of the rotating shaft.

がら該軸受け４０の製造方法を説明する。The clamp part 3 consists of a retainer 31 and a rotating shaft 32 made of a metal rod rotatably attached to the retainer. Both sides of the rotating shaft 32 are bent to form rotating rods 321, 321, and the upper end of the retainer 31 is removably engaged with the lower surface of the retaining part 15 protruding from the upper part of the recess 9. do. As shown in FIG. 7, the engaging portion 15 is formed in a bulge directly below the edge 44 of the opening 43 of the tank 2, and by forming the retaining portion 15 in such a position, the engaging portion 15 is formed to bulge out directly below the edge 44 of the opening 43 of the tank 2. opening 4
3 is prevented from deforming. Rotating rod 321.321
Protrusions 322, 322 are bent inward and protrude from the distal end portion. Recesses 33.33 are formed on the left and right sides with an interval T in the wall surface of the lower case 1b, and the recesses 33.
．． A hole 34° 34 is formed in the inner wall thickness of 33 to which the protrusion 322, 322 is rotatably engaged. In addition, a guide groove 35.35 is partially formed on the outer wall surface of the recessed part 33.33 to guide the fitting of the tip of the rotating rod 321.321 when the clamp part 3 is assembled to the main body case 1. . In Fig. 8, 34°34 is the rotation axis 3.
These bearings are the same as those shown in FIG. 11(a). Reference numeral 40 denotes an auxiliary bearing formed between the portions 34 and 34. Next, a method for manufacturing the bearing 40 will be described with reference to FIG. 9.

Reference numeral 36 indicates a groove portion formed in the member 35. The retainer 31 is made of thermoplastic material such as thermoplastic synthetic resin. It is made of material. The rotary shaft 32 is inserted into the concave groove portion 36.
After fitting, the ultrasonic generating part 37 of an ultrasonic welding machine (not shown) is pressed to the vicinity of the edge of the groove part 36 (see (a) in the same figure).
) to (c)). The lower surface 38 of the ultrasonic wave generator 37 is recessed in a circular shape, and the ends 39 and 39 on both sides thereof are pressed against the vicinity of the edge. When the ultrasonic generator 37 is pressed down while emitting ultrasonic waves, the edges are melted and the lower surface 3
8 (see the broken line in FIG. 8(C)). When the ultrasonic generator 37 is further pushed down, the edge is further fused and bent onto the rotating shaft 32, forming the bearing 40 (see FIG. 4(d)). The joint portion 41 of the bearing 40 bent in this manner is welded. Further, since the bearing 40 is bent along the circular lower surface 38, the rotating shaft 32
The lower surface 42 with which it comes into sliding contact is a smooth surface, and the rotating shaft 32 can rotate smoothly.
