Abstract

PROBLEM TO BE SOLVED: To provide an original idea of a locking mechanism capable of accurately gripping and constraining a member to be machined and other object, performing required machining effectively, and mounting and dismounting a body of a part to be machined smoothly by releasing easily and properly. SOLUTION: One end side of a locking shaft 6 is fixed to the body of the fixed part 11 such as a mold, and the other end side of the locking shaft 6 is fixed to a tightening block provided in a locking adjust on the movable part side through a machining raw material 7 and a locking guide 4.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the invention of a locking mechanism, which allows a member or other article to be machined to be accurately grasped and restrained, and to perform a required machining effectively. It is another object of the present invention to provide a mechanism which can be easily and appropriately released to smoothly mount and remove a workpiece. 2. Description of the Related Art It is necessary to hold and fix a target object when a target body is to be pierced or cut, etc. Has been proposed and adopted. [0003] In the above-described conventional mechanism for gripping and fixing a processing target object, even if the target body to be processed can be gripped and fixed to some extent, it is stable. In many cases, it is not easy to obtain a fixed target object, and the equipment configuration is generally large and cannot respond appropriately to changes in the thickness of the target body to be processed. It has disadvantages and disadvantages such as necessitating arrangements, and has a disadvantage that the gripping and fixing is not always stable, and it is released when an operation force greater than the setting is applied. In many cases, a mechanism for grasping and fixing a target object is exposed at least in a main part.
Therefore, it has disadvantages such as entanglement with other articles at the time of the locking operation, or a high possibility that foreign matter enters and adheres to the mechanism. The present invention has been studied to solve the disadvantages of the prior art as described above, and as a result, it has been found that the operating mechanism is housed in a housing. A structure in which a defect portion is appropriately covered allows a work material to be accurately grasped and fixed, and a locking shaft stably positions the operation mechanism and performs an effective locking operation to accurately obtain locking with respect to a target material. It has been successful as follows. [0006] One end of the locking shaft is fixed to a fixed part such as a mold, and the other end of the locking shaft is fixed to a tightening block provided in a movable part side locking adjust via a work material and a locking guide. A locking mechanism, characterized in that the locking mechanism is adapted to be used. [0007] One end of a locking shaft is fixed to a fixed body such as a mold, and the other end of the locking shaft is tightened with a working material and a locking guide provided in a movable part side locking adjust via a locking material. Since the locking shaft is fixed to the block, the locking shaft is set in a completely encapsulated state in the locking adjustment on the movable portion side from the fixed portion, thereby forming a properly protected locking mechanism. [0008] Further, at the time of tightening, the coupling between the locking tightening holder and the locking shaft is properly strengthened, and a large tightening force is effectively generated with a small tightening force at the time of locking. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention as described above will be described with reference to the accompanying drawings. A locking shaft 6 is provided at one end of a central portion of a cylinder block 10. An engagement portion 6a is formed on the base end side of the shaft 6, and locking engagement and holder members 5 and 5 attached to the engagement portion 6a by a shaft portion 15 are opposed to each other. 5,5
The operation unit 1 of the locking operation block 3 for the outer surface of
4 is facing. An end plate 10a attached to the end face of the cylinder block 10 is attached to a side member forming the cylinder block 10 with a mounting member 16, and the locking plate 4 and the locking guide cylinder 4 are attached to the end plate 10a. One of the locking members 11a is attached, and the processing material 7 and the locking member 11 are attached to the shaft 6 so that predetermined processing is performed. An opening 1 is mounted on the open end face of the other end of the cylinder block 10, and a tapered block 2 having a center hole 2a is mounted inside the opening 1 so that the above-described holder member 5, 5 proximal end taper 5
a so as to perform the above-described operation accurately. According to the present invention as described above, the members and other articles to be machined can be accurately locked and grasped and restrained by a relatively simple structure to perform the required machining effectively. In addition, the above-described locking state is appropriately released to enable smooth and easy loading and unloading of a target workpiece in a short time, and is an industrially significant effect.
