The bonded structure of the present invention comprises a metal body and a resin body, and is bonded at a metal side bonding portion of the metal body and a resin side bonding portion of the resin body. Further, in the first bonding structure, the resin body forms a gap between the resin member main body having the resin side bonding portion bonded to the metal side bonding portion and the metal body side protruding from the resinous member main body. And a protruding portion.

In this case, the resinous member main body of the resin body has a fully open opening on the metal body side, and forms a resin side space portion in a penetrating form having an opening having a protruding portion formed inward on the other side. It can be formed as Here, the totally open form means that there is no inward projecting portion on the side wall of the resin side space formed in the resin body. In other words, when the resin body is manufactured by injection molding, the mold can be taken out vertically from the opening as it is.

In addition, as another resin body, the projecting portion can be formed to project outward from the resinous member main body.

The projecting portion may be in the form of an inward or outward facing circumferential flange.

In the second bonding structure, on the contrary, the metal body is between the metal member main body having the metal side bonding portion to be bonded to the oil side bonding portion and the resin body side protruding from the metal member main body. And a protruding portion forming a gap.

In this case, the metallic member main body of the metal body forms a metal side space portion of the penetrating form having the opening of the fully open form on the resin body side and the opening having the projecting portion formed inward on the other side. It can be formed as Further, as another metal body, the projecting portion can be formed to protrude outward from the metallic member main body. In these cases, the projecting portion may be in the form of an inward or outward facing circumferential flange.

Such a joining structure is joined by electric current heating joining because the mold can not be easily removed from the gap in the insert molding.

For example, as disclosed in Japanese Patent Application Laid-Open No. 2013-166349, electric heating and heating bonding is a technology of heating a metal body by energizing and pressing directly the metal body and the resin body to bond (adhere). . Unlike the adhesive, the molecular bonding between the metal body and the resin body is different from that of the adhesive, and moisture and the like do not enter the bonding surface, so the bonding state is maintained for a long time. In particular, by applying a TRI treatment (surface treatment) to a bonding surface of metal, the resin and the TRI treatment can be molecularly bonded to be strongly bonded. Bonding strength can be further enhanced by subjecting the metal side to anchor treatment.

In Japanese Patent Application Laid-Open No. 2013-166349, the invention of a bonding method (fixing method) by current heating of a resin body and a metal body is described in detail. Specifically, when the metal body is energized to reach a predetermined set temperature, the metal body and the resin body are put together while maintaining the set temperature, and a predetermined pressure is applied to bring the metal body into a pressed state to continue for a predetermined time. When the time has elapsed, the current application is terminated, and while the pressure is applied, cooling is performed by the cooling mechanism to complete the fixation. The set temperature is a softening temperature of the resin body or a predetermined temperature higher by about 1 ° C. to several tens of ° C. than the softening temperature of the resin body, and is appropriately set in advance by trial experiments. However, the set temperature is less than the melting temperature of the resin body, and more preferably a temperature significantly lower than the melting temperature of the resin body.

As a result of conducting a tensile shear test about the joined member of the combination of several types of resin bodies and several types of metal bodies, in all the tests, the resin body fractured and the adhering site did not peel. From this, it is clear that the bonding strength is extremely strong.

For example, it may be cut and formed from a solid material by an automatic cutting machine such as a machining center.

The resin body may be any resin as long as it can be joined to the metal body by electric heating and bonding, and synthetic resins such as polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), polyamide (PA) and natural resins are listed. Be Further, the shape of the resin body is appropriately formed by a conventional method such as injection molding.

Alternatively, laser bonding may be used instead of current-heated bonding. In this case, a transparent resin that can transmit laser light may be used as the resin body. Examples thereof include synthetic resins and natural resins such as polycarbonate, ABS resin, polycarbonate ABS (PCABS), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), and polyolefin resins.

The cylinder described in FIG. 24 is a cylinder 600 including a metal cylinder chamber forming portion (metal body 620) forming a cylinder chamber and a cylinder complementary portion (resin body 610) joined to the outside of the cylinder chamber forming portion. To which the bracket of the present invention is applied. The cylinder complementing portion is preferably joined to the outside of the cylinder chamber forming portion so that the cylinder chamber is airtight.

Here, the cylinder means, for example, a cylinder made of metal and resin as disclosed in JP-A-2011-196459. That is, a metal cylinder tube is mainly formed by a cylinder chamber forming portion forming a cylinder chamber, and a resin cylinder complementing portion fixed to the outside of the cylinder chamber forming portion. Further, when the cylinder tube can be reciprocated, the piston rod 651 can be reciprocated by the action of the fluid pressure by providing the piston operating in the cylinder chamber by the action of the fluid pressure.

The cylinder chamber forming portion has a metal cylinder tube and a cover closing the opening of the cylinder tube, thereby forming the cylinder chamber.

The cylinder tube is made of, for example, a metal such as iron, stainless steel, aluminum, copper, titanium, brass or an alloy thereof, and has a cylindrical shape with both ends open or a bottomed cylindrical thin structure with one end open. Further, in the cylinder tube, a suction / discharge port for suction / discharge of fluid such as gas or liquid in the cylinder chamber is formed. If a step-like groove capable of locking a cover described later is provided on the inner wall on the opening side, assembly and the like become easy.

The cover is formed according to the cross-sectional shape of the inner wall of the cylinder tube, and closes the opening in the axial direction of the cylinder tube to form a cylinder chamber. When the cylinder tube has a cylindrical shape opened at both ends, it comprises a head cover closing the opening at one end of the cylinder tube and a rod cover closing the opening at the other end of the cylinder tube. Further, in the case where the cylinder tube has a bottomed cylindrical shape, only the rod cover that closes the opening at one end may be used. Here, the shape of the cover is formed so as to abut on the cylinder tube when closing the opening of the cylinder tube, and does not separate from the cylinder tube integrally by fixing the cylinder complementary portion described later It is preferred to have a structure.

The rod cover is formed with a rod hole through which the piston rod 651 can be inserted substantially at the center thereof. Further, between the piston rod 651 and the rod hole, a bush and a piston packing can be disposed, whereby the cylinder chamber can be made airtight.

The material of the cover may be, for example, a metal such as iron, stainless steel, aluminum, copper, titanium, brass or an alloy of these. Also, it may be made of resin.

The cylinder complementing portion is a structure for complementing the function of the cylinder, and is formed on the outside of the cylinder chamber forming portion using a resin. For example, a pressure resistant reinforcing portion is formed which covers the outside of the cylinder tube or the cover and reinforces the pressure resistant strength thereof. As the resin, for example, polyphenylene sulfide (PPS), polybutylene terephthalate (PBT), nylon, polyphthalamide (PPA), ABS resin, polystyrene (PS) or the like can be used.

In addition, the cylinder complement may also form a seal so as to close the space between the cylinder tube and the cover in order to make the cylinder chamber airtight.

In addition, a sensor for mounting a sensor for detecting the position of the piston, and a suction and discharge section for connecting a pipe that sucks and discharges fluid such as gas or liquid to the cylinder chamber through the above-mentioned suction port. The parts may be integrally formed. The sensor mounting portion may have any shape as long as it can mount a sensor for detecting the position, but for example, the axial direction of the cylinder tube (moving direction of piston described later) on the outside of the cylinder tube Are formed as concave sensor attachment grooves or convex sensor attachment rails extending along the In addition, a plurality of the sensor attachment grooves may be provided, and the sensor attachment grooves may be formed on surfaces facing each other around the cylinder chamber.

The piston rod 651 is formed in a rod-like or hollow cylindrical shape made of a metal such as iron, stainless steel, aluminum, copper, titanium, brass or an alloy thereof, and one end side of the piston rod 651 in the axial direction is The piston is attached.

The piston is formed approximately the same size as the inner wall of the cylinder tube. Thus, the cylinder chamber is divided into a first cylinder chamber on the rod cover side and a second cylinder chamber on the head cover side (the bottom side of the cylinder tube when the cylinder tube is formed in a bottomed cylindrical shape). Then, when a fluid such as air, for example, is drawn into the first cylinder chamber from the first suction / discharge portion for supplying the fluid to the first cylinder chamber and pressurized, the piston moves to the head cover side. Also, when air is sucked into the second cylinder chamber and pressurized from the second suction / discharge section that supplies fluid to the second cylinder chamber, the piston moves to the rod cover side. Thus, the piston and piston rod 651 reciprocate in the cylinder chamber by the action of fluid pressure.

In the embodiment, the cylinder chamber forming portion forming the cylinder chamber is a metal body 620, and the cylinder complementary portion is a resin body 610. From the resinous member main body corresponding to the conventional cylinder complementary portion, a projecting portion 619 forming a gap with the metal body 620 side is formed so that the connecting projecting portion 719 of the other connecting bracket 700 can be fitted. Ru.

Further, in the connection bracket 700, the connection protrusion portion 719 protrudes inward from the resinous member main body to the metal body 720 provided with the fixing hole 730 for fixing the bracket 700 in a desired position by a screw or the like. The resin body 710 is joined. The metal body 720 has a ridge portion bent perpendicularly to the surface of the resin body 710 on which the resin-side bonding portion is located, and a fixing hole 730 is formed in the ridge portion.

By forming the cylinder 600 in this manner, the number of parts for mounting the cylinder 600 can be reduced and the process for mounting can be simplified. Moreover, since it is not necessary to use a tool etc., a cylinder can be easily attached also to very narrow space. In addition, the weight can be reduced as compared with the conventional one, and the use application can be expanded.
