Embodiment 1

[0038] This embodiment provides a fixed clamping assembly. The main structure is composed of a connecting rod 1, a support block 2 and a stopper 3; And the outer diameter of support block 2 is all smaller than the inner diameter of workpiece cylinder 5. When in use, one end of the connecting rod 1 is used for coaxial connection with the end of the corrugated lower mold 4; the outer wall of the support block 2 is used for contacting in the annular groove between the adjacent corrugated channels formed in the workpiece cylinder 5, It is used to balance the workpiece cylinder 5; the end surface of the stopper 3 facing the support block 2 is used to abut and contact the end surface of the workpiece cylinder 5 away from the corrugated lower mold 4 .

Embodiment 2

[0040] Further improvement on the basis of Example 1, the stopper 3 is provided with a slit 6, and the stopper 3 has a disconnected circular ring structure as a whole, and the slit 6 is gathered toward the closing direction by the locking member to realize the stopper 3 It is fixedly connected with connecting rod 1. The locking part adopts bolt 7, and a through hole is opened on one side of the gap 6, and a threaded hole is opened on the other side. The axis lines of the through hole and the threaded hole coincide. fixed in the hole. The stopper 3 is made of nylon material, and the width of the gap 6 is 1 mm to 5 mm, preferably 2 mm to 3 mm, 2 mm in this embodiment; the stopper 3 is connected with the connecting rod 1 through interference fit.

Embodiment 3

[0042] Further improvement on the basis of Embodiment 2, the support block 2 is in the form of a ring structure, and the support block 2 is connected with the connecting rod 1 by an interference fit socket, and the axial length of the support block 2 is smaller than the width of the annular groove.

Abstract

The invention discloses a fixed clamping assembly, which comprises a connecting rod, a supporting block and a stopper; the connecting rod is provided with a supporting block and a stopper concentrically in sequence; when in use, one end of the connecting rod is used for The ends of the mold are coaxially connected under corrugation; the outer wall of the support block is used in the workpiece cylinder to form an annular groove in contact with it, and is used to balance the workpiece cylinder; the end face of the stopper facing the support block is used to contact the workpiece The end surface of the cylinder away from the mold under the corrugation is in contact with each other. The effective and simple assembly of the invention ensures the quality and production efficiency of the bellows, and solves the phenomenon that the corrugations are easy to deviate during the production process, the same corrugation is not on the same circumference of the platinum cylinder, and the product is scrapped; the number of cooperating personnel is reduced, and the platinum corrugation is guaranteed. tube quality and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a fixed clamping assembly. Background technique [0002] Platinum is used as the melting channel in the preparation process of optical glass and liquid crystal substrate glass. The melting point of platinum is about 1700°C. However, when melting glass at high temperature, especially at 1450°C, platinum products will be deformed by heat and their strength will decrease. Therefore, it is necessary to increase Corrugated structure to ensure the high temperature strength of platinum. The platinum corrugation is made by clamping the mold with the pressure equipment. After the pressure equipment is started, the corrugated convex-concave mold rotates with the equipment and gathers closer. After the rotating convex-concave mold touches the platinum surface, it drives the platinum cylinder to rotate and forms corrugations on the surface. At this time The platinum cylinder i...
