In order to achieve the above object, the general-purpose workpiece holder according to an embodiment of the present invention includes a workpiece holder for gripping a workpiece to process a workpiece, which is a part of a mold or a fixture such as a punch, a die, a holder, and the like. There are: a base having a guide groove formed at an upper portion thereof, a fixed gripping zone fixed to one side of the guide groove by a dowel pin and a fixing bolt, and having one side of the workpiece contacted, and various sizes at one side of the guide groove opposite to the workpiece. The guide groove is moved to a predetermined pitch in order to grip the workpiece to be fixed to the base by a fixed bolt and the other side of the workpiece to contact and fix the workpiece to the fixed gripper A sliding gripper which is guided and slid to the sliding gripper, and the movable gripper slides the sliding gripper with respect to the movable fixing block It is characterized in that comprises a grip adjusting bolt provided in the internal thread of the block.

In this case, according to the shape of the contact portion of the workpiece, both the contact portions of the fixed gripper and the sliding gripper may be formed in various shapes such as a plane, a point, an arc, or the like. It is further desirable that gripping blocks of various shapes such as planes, needles, arcs and the like can be inserted interchangeably.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view of a universal workpiece according to an embodiment of the present invention in a plan view, Figure 2 is a right side view of Figure 1, Figure 3 is a cross-sectional view of FIG.

1 to 3, the workpiece holder for holding the workpiece WP for processing the workpiece WP which is a part of a mold or a fixture such as a punch, a die, a holder, etc. includes a base 10 and a fixed wave. It comprises a zone 11, a movable fixing block 12, a sliding grip 13 and a gripping adjustment bolt 15.

The base 10 is formed with a guide groove 10a for guiding the precise sliding of the sliding grip 13.

The holding grip 11 is fixed to the base 10 by the dowel pin 11a and the fixing bolt 11b at one side of the guide groove 10a, and in this state, one side of the workpiece WP contacts. do.

The movable fixing block 12 is fixed to the base 10 by a fixing bolt 12a on one side of the guide groove 10a opposite to the fixing grip 11 with respect to the workpiece WP, and has various sizes. It is configured to be fixed by moving to a predetermined pitch in order to hold the workpiece (WP).

The sliding grip 13 is guided and slides in the guide groove 10a so that the other side of the workpiece WP contacts and fixes the workpiece WP to the fixed grip 11. The distance of the pitch of the movable fixing block 12 is slidably installed.

The gripping adjustment bolt 15 is attached to the female screw 12b of the movable fixing block 12 so as to slide the sliding gripping stand 13 with respect to the movable fixing block 12. It is preferable that the length of the gripping adjustment bolt 15 is slidable by a distance equal to or more than the pitch of the movable fixing block 12.

In the case of the workpiece WP having a large size by such a configuration, after dismantling the fixing bolt 12a in FIG. 3, the distance between the fixed grip 11 and the sliding grip 13 of the retracted position is avoided. After moving the position of the movable fixing block 12 backward with a clearance (within pitch) than the grip length of the workpiece WP, the fixing bolt 12a is fixed again. Thereafter, the grip adjusting bolt 15 is rotated so that the sliding grip 13 is moved forward and the workpiece WP is firmly gripped with respect to the fixed grip 11 to fix the workpiece WP. The setting operation is completed. Therefore, the setting work of the workpiece WP can be made easily and conveniently.

Figure 4 is a plan view of the universal work fixture according to another embodiment of the present invention.

Since the workpiece WP has a variety of forms and materials, it is desirable to be able to hold the workpiece WP in a more diverse form. To this end, in another embodiment of the present invention, as shown in Figure 4, the grip block (16, 17) of the workpiece (WP) of the fixed grip 11 and the sliding grip 13 so as to be removable It is installed near the contact part.

The contact portion of the workpiece WP of the gripping blocks 16 and 17 may be formed in various shapes such as a plane, a point, an arc, and the like. On the other hand, the shape of the workpiece (WP) contact portion of the fixed grip 11 and the sliding grip 13 can be formed in various shapes such as flat, point (needle), circular arc, etc. without the holding blocks (16, 17). However, it is possible to set a variety of workpiece (WP) more easily configured to be replaced as needed.

When starting work on the current workpiece (WP), the workforce workers are always setting up for the new workpiece and always holding the various blocks for installation, and the machining of the workpiece (WP) There is a considerable amount of time lost for this purpose, and the resultant waste of the entire facility or human resources is always occurring. Thus, based on this reality, the enormous waste and loss of time, mechanical and human resources in the setting can be reduced by the universal workpiece holder of the present invention.

To summarize the features and advantages of the universal workpiece fixture according to the embodiments of the present invention described above.

1. Features
