筒の締付装置。[Scope of Claim for Utility Model Registration] (1) A tightening device for a heat jacket that is attached to the outer periphery of a gun barrel to equalize and radiate heat from the gun barrel, which has a notch in the axial direction at one point on the periphery. First and second tension rods, each of which is a pipe body, are loosely fitted and supported at both ends of the heat jacket along the notch of the heat jacket through a flange member, with respect to the heat jacket having a C-shaped cross section. and a screw hole drilled in the first rod and a second screw hole opposite to the screw hole between the plurality of fastening parts set dispersedly on the axis of the tension rod.
a fastening bolt that straddles a notch groove formed in the rod and tightens the bolt between both rods;
A disc spring is fitted onto the bolt shaft between the second tension rod and the head of the fastening bolt, and also serves as a positioning member for the tightening stroke of the disc spring, and the tip of the leg is connected to the second tension rod. and a disc spring housing with legs configured to fit into the cutout groove of the tension rod and engage with the inner wall surface of the pipe, and the tension rod can be mounted on the gun barrel with a heat jacket attached to the gun barrel. By screwing in the fastening bolts across the joints and applying a predetermined tightening stroke to the disc springs based on the disc spring housing engaged with the second tension rod, the disc springs are compressed at each joint in the heat jacket. A heat jacket tightening device characterized in that each device is configured to obtain a predetermined tightening force. (2) In the tightening device according to claim 1 of the utility model registration claim, the belleville spring housing is a bottomed cylinder with legs that has a bottom portion that serves as a spring receiving seat and legs that protrude rearward from the bottom portion. As a body,
A heat jacket tightening device characterized in that the axial length of the cylindrical portion is set to a length corresponding to the tightening stroke of a disc spring that applies a predetermined tightening force to the fastening portion. (3) In the tightening device according to claim 1 of the utility model registration claim, the cutout groove formed in the second tension rod is connected to the bolt fitting groove into which the fastening bolt is fitted and the leg of the disc spring housing. A heat jacket tightening device characterized by having a plurality of notched grooves in combination with leg engaging grooves that engage with each other. (4) The tightening device according to claim 1 of the utility model registration claim, characterized in that the fastening bolt is provided with a stopper member at the tip of the bolt shaft to prevent it from falling off from the first tension rod. Clamping device for the jacket.
