Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vise that clamps and fixes an object.

[0002]

[Prior Art]

 Generally, this type of vise has a U-shaped cross section, which is composed of the left and right side faces 2 and 23 facing each other and the bottom face 4 connecting the both side faces, as shown in FIGS. 3 and 4. The base block 20 is slidably supported by the two support rods 5 and 5 spanning the side surface portions 2 and 23, and the distance between the left side surface portion 2 and the left side surface portion 2 becomes freely movable. Has a slide block 26 for sandwiching and fixing it, and a screw portion 11 that is screwed into a screw hole 23a formed in the other side surface portion 23, and has a tip with a small diameter and is formed in the recessed portion 26a of the slide block 26. The feed shaft 30 is composed of a mounting portion 32 that is rotatably connected by and a grip portion 13 provided at the other end.

With such a configuration, when the grip portion 13 of the feed shaft 30 is rotated clockwise in FIG. 3, the male screw portion 11 screwed into the screw hole 23a advances to the left to cause a slash. The id block 26 is slid to the left along the support rod 5 to be brought close to the left side surface portion 2 of the base block 20, and the slide block 26 and the left side surface portion 2 sandwich and fix the object. Further, when the grip portion 13 is rotated counterclockwise, the slide block 26 is separated from the left side surface portion 2 and the object can be removed.

[0004]

[Problems to be solved by the device]

 In the conventional vise described above, the movement of the slide block is solely due to the amount of advancement of the screw part accompanying the rotation of the feed shaft, so to slide the slide block a long distance to hold a thin object. However, there is a drawback that the feed shaft needs to be rotated by a considerable amount, which is a troublesome work and takes a long working time.

Therefore, the present invention has been made in view of the above-mentioned conventional drawbacks, and an object thereof is not only to rotate the slide block but also to directly rotate the feed screw. The purpose is to provide a vise that can be pulled and slid to reduce the work time for clamping and fixing.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the vise according to the present invention comprises a base block having a U-shaped cross section, which is composed of opposite side surface parts and a bottom surface part connecting both side surface parts, and the vise according to the present invention. A slide block that is slidably supported by the passed support rod so that the distance from one side surface of both side surfaces can be moved closer to and away from it, and screwed into a screw hole formed in the other side surface to advance and retreat to this side surface. A vise composed of a feed screw whose one end is freely connected to the slide block, which connects the slide block and the feed screw with a spherical journal, and which feed screw into the screw hole of the side surface. It has an opening that can be attached and detached.

[0007]

[Action]

 In the present invention, the feed screw can swing about the spherical journal as a fulcrum, the screw engagement with the feed screw is released from the opening of the screw hole, and the slide block can be directly pushed and pulled by the feed screw.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a vise according to the present invention, and FIG. 2 is a side sectional view of the same. In these figures, a substantially upper half of the right side surface portion 3 which is one side surface portion constituting the base block 1 is removed, and a screw hole 3a having a saw tooth shape is formed in a semicircular shape. An opening 3b is provided, and the screw portion 11 of the feed screw 10 can be freely attached to and detached from the opening 3b and the screw hole 3a.

A recess 6a having a square cross section is formed in the center of the slide block 6, and a ball bearing 8 is embedded and fixed in the recess 6a. On the other hand, a ball portion 12 is formed at the tip of the feed shaft 10, and the ball portion 12 is fitted into the ball bearing 8 to form a journal bearing, and the feed shaft 10 supports the ball bearing 8 as a fulcrum. As a result, it can swing freely.

In the vise configured as described above, when the slide block 6 is moved to clamp and fix an object between the slide block 6 and the left side surface portion 2 of the base block 1, first, the feed shaft 10 is moved to a ball. Using the bearing 8 as a fulcrum, the screw portion 11 is lifted upward from the opening 3b of the screw hole 3a to release the screw engagement between the screw hole 3a and the screw portion 11, and then the feed shaft 10 is moved to the left and right in FIG. It is pushed and pulled, and the slide block 6 is moved directly along the support rod 5.

Next, the feed shaft 10 is lowered with the ball bearing 8 as a fulcrum, the screw portion 11 is screwed into the screw hole 3a again from the opening 3b of the screw hole 3a, and the feed screw 10 is rotated. , The slide block 6 is slightly moved, and the slide block 6 and the left side surface portion 2 of the base block 1 sandwich and fix the object. In this case, the repulsive force generated when the object is sandwiched and fixed between the slide block 6 and the left side surface portion 2 of the base block 1 is the vertical surface of the sawtooth screw formed in the semicircular screw hole portion 3a. Since it is received by the side, the feed shaft 10 does not float, and an object can be clamped and fixed by a force equivalent to a conventional vise.

[0012]

[Effect of the device]

 As described above, according to the present invention, a slide block for holding and fixing an object and a feed screw are connected by a spherical journal, and an opening portion through which the feed screw is detachable is provided in the screw hole of the side surface portion. Since it is provided, the feed screw can be rotated to slide the slide block, and it can also be slid by removing the feed screw from the opening of the screw hole and lifting and pushing it. However, not only the rotation of the feed shaft, but also the slide block can be easily moved directly by pushing and pulling, which has the effect of significantly reducing the work time.
