Abstract

The present invention relates to a mechanical power increasing apparatus for a vise, comprising: four tilted guide grooves formed in a cross shape on one surface of a body; and a vertical guide groove corresponding to the tilted guide groove of the body formed in a cross shape on one surface of a support body, wherein four movable steel beads are disposed along the tilted and vertical guide grooves between the tilted guide groove of the body and the vertical guide groove, and each steel bead disposed in a bead guide groove of a pressing device. As such, when the pressing device moves forwards by pressing a forwarding shaft, the four steel beads are pushed outwardly along the tilted guide groove of the body, the vertical guide groove of the support body, and the bead guide groove of the pressing device such that an increased power is applied. According to the present invention, when the forwarding shaft operated by a handle while being mounted inside the vice presses the pressing device, independently movable steel beads are able to be moved along the tilted guide groove of the body and the vertical guide groove of the pressing device; thereby uniformly distributing a force of the pressing device to the four steel beads to provide a bigger force. Moreover, when an impact is applied to a workpiece fixated in the vice, the four steel balls divide and absorb the impact; thereby being able to precisely process the workpiece, and thus being able to strongly hold a position wherein the workpiece is fixated.

Description

[0001] The present invention relates to a power increasing control unit for vise,

[0001] The present invention relates to a mechanical lifting device for a vise, and more particularly to a mechanical lifting device for a vise which is capable of applying a greater force to a vise by a pushing- ≪ / RTI >

In general, a vise is a tool that fixes a position to machine a workpiece, and a vice is divided into a manual (machine) vise and a mechanical type vise.

In addition, the manual vise is used to fix a position by fixing a position that can be finely hand-machined, and is used to reduce the size and accuracy of the workpiece to be machined or finished and to apply the workpiece with a weak pressure.

In addition, the mechanical type power vice is used when a workpiece requiring higher precision than the manual vice is fixed with a strong pressure. However, this phenomenon occurs when the workpiece is moved without being fixed at a fixed position during machining So that the machining accuracy of the workpiece is lowered.

In order to solve such a problem, as shown in Fig. 1, a mechanical lifting device for a vise has an engagement hole 11 penetrating from the front to the back at the center of the body, And a sloped portion 15 having a sloping surface 14 is formed on the rear surface at the upper and lower sides of the body. The sloped portions 15 are formed at regular intervals in the center of the body, A body having a first guide groove (16) formed with a predetermined width from the bottom to the top; And the first roller 21 is rotatably coupled to the upper portion of the first guide groove 16 and the lower portion is opened to the lower portion of the second guide groove 16, A first guide plate 20 having a guide groove 24 coupled to the roller 22 to guide the movement of the second roller 22; And a first roller 21 is coupled to the upper portion of the first guide groove 16 so as to be slidably engaged with the first guide plate 20, A second guide plate 30 to which a second roller 22 is rotatably coupled; The first and second rollers 21 and 22 are connected to each other through the coupling hole 11 of the body so as to protrude with a predetermined length from the front, ; A second guide groove 51 having a predetermined width at both sides of the body is formed at a front side of the first guide groove 20 so as to correspond to the first guide groove 16, (50) having a coupling groove (52) fitted in the other end of the body (10) so as to be slidable and having a screw groove formed on an inner side surface at a position corresponding to the through hole (12) of the body; And is fixed to a fastening groove 52 of the support portion 50. The spring support jaw 13 of the through hole 12 and the head portion 60a, a spring member 61 is coupled between the upper and lower rollers 60a, 60a, 60b, 60b, 60c, 60d, The second roller 22 is fixed and only the first roller 21 is moved up and down along the guide groove 24 so that even if the presser advances, only the two rollers can be pressed, In addition, the pressure is not smooth and the structure is complicated, making it difficult to manufacture. Therefore, the manufacturing cost is high. When a strong impact is applied to the workpiece fixed to the vise, the two rollers are dispersed to absorb shock, It has the disadvantage difficult to precisely machine the workpiece.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The mechanical lifting device 100 for a vise according to the embodiment of the present invention includes a through hole 111 formed at the center thereof, a plurality of screw holes 113 formed around the through hole 111, A supporting body 120 coupled to the body 110 by a screw 150 having a spring 160 interposed therebetween, a support body 120 having four inclined guide grooves 112, And a pusher 140 coupled to the other side of the body 111 so as to protrude by a predetermined length and having a conical end.

The four inclined guide grooves 112 are formed in a cross shape at one side of the body 110 and the vertical guide grooves 112 corresponding to the inclined guide grooves 112 of the body 110 are formed on one side of the support body 120. [ (122) are also formed in a cross shape. At this time, it is preferable that a concave groove 121 is formed at the center of the support 120, into which a pushing member 140 for advancing can be inserted.

Four iron balls 130 (130) are provided between the inclined guide grooves 112 of the body 110 and the vertical guide grooves 122 of the support body 120 and are movable along the inclined guide grooves 112 and the vertical guide grooves 122. And the respective iron balls 130 are arranged in the bead guiding grooves 141 of the pressing tool 140. When the pressing tool 140 advances by the pressing of the advancing axis C, The iron ball 130 is guided by the bead guide groove 141 of the pusher 140 and the inclined guide groove 112 of the body 110 and the vertical guide groove 122 of the support 120 and pushed outward Let the force work.

One side of the body 110 may have a concave groove that is recessed toward the center of the body 110 to prevent the beads 130 from being separated from the body 110. [ .

A hole 111 is formed at the center of the body 110. The hole 111 is fitted with a presser 140 having a predetermined length and a conical end.

The pusher 140 protrudes a predetermined length from the front surface of the body 110 and a bead guide groove 141 for guiding the rolling of the four beads 130 is formed in the cone portion of the pusher 140 As shown in FIG. 6, when the pressing member 140 is pressed, the pressing member 140 moves toward the supporting member 120, and the iron ball 130 moves toward the supporting member 120, It is climbed by the photograph bead guide groove 141 and pushed outward.

When the body 110 is moved toward the supporting body 120, the body 110 is expanded with strong pressure, so that when the body 110 is moved toward the supporting body 120, Pressure is transmitted to the movable body holding the workpiece, and the workpiece is strongly asked to fix the position.

In other words, in the state where the movable body applies pressure to the workpiece under a strong pressure, even when an impact is applied to the workpiece or the movable body, the buffering action is not generated and the pressure generating action is maintained. Thus, the position of the workpiece can be prevented from being changed.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
