Fixed pressure enhancer for vise {FIXED PRESSURE REINFORCEMENT DEVICE FOR A VISE}

The present invention relates to a fixed pressure increasing device for a vise, and more specifically, a small roller frictionally driven by a pressure port, a middle roller directly driven by a small roller, and a combination of rollers to prevent the rear pressure of the middle roller. The pressure transmitted to the rear body (toward the first body side) while the linear movement by the pressure port is transmitted to the middle roller by the small roller to pressurize the second body on which the inclined surface in contact with the roller is formed. The present invention relates to a fixed pressure increasing device for a vise comprising small, medium and large rollers of different sizes so as to be effectively prevented by this roller.

In general, a vise is used as a means for reliably fixing a workpiece when machining each component constituting various products, and has a structure of various shapes depending on the type of workpiece and the machine to be processed.

In general, the type of vise widely used is a manual vise used for processing or finishing a workpiece by hand, and for a machine that requires mass production and precision processing, or a relatively large size of a workpiece and a high fixed pressure is required. There is a hydraulic vise used in the case.

Hydraulic vise has a variety of configurations, depending on the hydraulic drive method for driving the working fluid (working fluid), there is an advantage to maintain a constant and constant constant pressure without changing the high fixed pressure which is a characteristic of the hydraulic pressure.

However, the conventional method of fixing the hydraulic vise has a disadvantage in that when the impact is applied from the outside to the work piece fixed by the hydraulic vise, the hydraulic pressure is momentarily buffered so that the exact fixed position of the workpiece cannot be maintained.

In addition, when bubbles are generated or oil leakage occurs in the working oil used as the pressure means, the fixed pressure is gradually lowered, thereby preventing the normal fixation of the workpiece.

As a way to solve the disadvantages generated in the conventional hydraulic vise as described above, the 'vice vise booster' is pre-registered as Utility Model Registration No. 270284.

The utility device for vise of the Utility Model No. 270284 is shown in a perspective view and a cross-sectional view in Figures 1a and 1b,

Coupling holes are formed through the center of the body portion from the front to the rear side so that the fitting holes 30 are fitted, and bolt coupling holes 12 having spring support jaws (not shown) are provided at both sides of the front. It is drilled to the rear side (right in Fig. 1), the rear side is formed with inclined surfaces (13a, 13b) in contact with the roller to the body center side symmetrically from the upper and lower, and both sides of the inclined surfaces (13a, 13b) with a predetermined width A first body portion 10 having a first guide groove 11 formed therethrough;

The second guide groove 21 penetrates vertically with a predetermined width corresponding to the first body portion 10, the female threaded hole is formed corresponding to the bolt coupling hole 12, and the first body portion 10 is formed. A second body part 20 which is linearly moved by the first and second rollers 42a, 42b; 43a, 43b driven by the linear movement of the pressure port 30 coupled to it;

The first and second rollers 42a are fitted into the first guide groove 11 and the second guide groove 21 of the first body portion 10 and the second body portion 20 so as to slide upward and downward simultaneously. Guide plates 40a, 40b; 41a, 41b having coupling holes to which 42b; 43a, 43b are coupled; and first and second rollers engaged with the guide plates 40a, 40b; 41a, 41b. 42a, 42b, 43a, 43b);

Compression fitting 30 is inserted into the through-hole coupling hole 12 of the first body portion 10 to drive the first and second rollers 42a, 42b; 43a, 43b.

In the conventional vise booster configured as described above, when the pressure port 30 is linearly moved to secure the workpiece, the first vise booster device is symmetrically between the first body portion 10 and the second body portion 20 and the upper and lower portions. Among the arranged first rollers and second rollers 42a, 42b; 43a, 43b, the first rollers 42a, 42b in contact with the inclined surfaces 13a, 13b are rotated to drive the first rollers 42a, The second rollers 43a and 43b engaged with 42b are rotated while the first rollers 42a and 42b are rotated and moved outward of the inclined surfaces 13a and 13b, so that the first and second rollers 42a and 42b are rotated. Guide plates 40a and 40b for supporting 43a and 43b are guided to the first and second guide grooves 11 and 21 from the center to the outside, ie, up and down, respectively, and slide.

At this time, since the first body 10 is completely fixed, and the second body 20 is fastened by a bolt 50 fitted with a spring (not shown), the pressure port 30 is used. The second rollers 43a and 43b move the second body 20 forward by the first rollers 42a and 42b rotated on the inclined surfaces 13a and 13b, and thus the second body 20 is moved forward. The fixed pressure of the vise is increased by forward movement. The spring (not shown) coupled to the coupling bolt 50 of the first body 10 by the front movement of the second body 20 is in a compressed state.

However, since the first rollers 42a and 42b and the second rollers 43a and 43b rotated by the pressure port 30 have the same size, the first wheel of the vise augmentation device may not be smoothly formed.

In addition, the inclined surfaces 13a and 13b are formed on the rear surface of the first body part 10 so that the force is rotated backward when the first and second rollers 42a, 42b; 43a and 43b are driven through the pressure port. Since the first body is first delivered to the body 10 and then secondly forwarded to the front, there is a problem in that a force transmission loss occurs.

The present invention was developed to solve the conventional problems as described above

An inclined surface is formed on the rear surface of the second body to be linearly moved, and the roller is rotatably coupled to the guide plate to linearly move the inclined surface. The roller comprises a first roller, a second roller, and a third roller. The first roller is in direct contact with the small roller, the second roller is engaged with the first roller and is in contact with the inclined surface of the second body, and the third roller is engaged with the second roller. It consists of a large roller located just behind the two rollers, so that the rotational driving of the rollers that transmits the force of the pressurizing port is smooth and prevents the force transfer to the rear, improving the straightness of the force forward. .

As illustrated in the figure, the upper and lower first rollers 430a and 440a in direct contact with the wedge-shaped pressure port 300 are upper and lower second rollers 430b and 440b positioned outside the front of the first roller. And the upper and lower second rollers 430b and 440b are respectively engaged with the upper and lower third rollers 430c and 440c positioned immediately behind the second roller.

Accordingly, when the wedge-shaped pressure port 300 coupled to the first body 100 is linearly moved from the rear (right in FIG. 2) to the front (to the left in FIG. 2), that is, the second When moved in the direction of the body 200, the upper and lower first rollers 430a and 440a in engagement with the pressure port 300 are moved upward and downward, respectively. At the same time, the left and right guide plates 410a, 410b; 420a, 420b, which support the upper and lower first rollers 430a, 440a, also have first and second guides of the first body 100 and the second body 200. Guided by the grooves 110 and 210, the slide is moved up and down, respectively.

In addition, since the upper and lower first rollers 430a and 440a, which are moved up and down by the linear movement of the pressing hole 300, are engaged with the upper and lower second rollers 430b and 440b, respectively, the right side in FIG. As the pressing hole 300 is moved from the left side, the upper first roller 430a located above the pressing hole 300 also rotates in a clockwise direction, and thus the upper second roller engaged with the upper first roller 430a. The lower first roller 440a is rotated counterclockwise in a direction opposite to the upper first roller 430a and is engaged with the lower first roller 440a while the 430b is rotated counterclockwise. Roller 440b is rotated clockwise.

The upper and lower second rollers 430b and 440b are in contact with the upper and lower inclined surfaces 220a and 220b of the second body 200 and guide plates 410a and 420a supporting the upper second roller 430b. As the upper upward roller 430b moves up the upper inclined surface 220a of the second body 200, the lower second roller 440b is lower inclined surface 220b of the second body 200. As a result, the second body 200 having the upper and lower inclined surfaces 220a and 220b is forcibly moved forward.

When the second body 200 is forcibly moved forward (when the second body 200 is moved away from the first body 100) to connect and fix the first body 100 and the second body 200 The spring 520 coupled to the bolt 510 is changed into a compressed state.

The second body 200 moved forward by the upper and lower second rollers 430b and 440b is in a state where the force of the spring 520 is always acted to return to the rear side (the first body 100 side).

A guide plate having a bolt hole 120 and a screw hole 230 formed in each of the 200 is formed, and the upper and lower first to third rollers 430a and 440a; 430b and 440b; 430c and 440c are rotatably coupled thereto. Guide grooves 110 and 210 are formed perpendicularly to the first body 100 and the second body 200 so that the first and second bodies 410a and 410b and 420a and 420b are guided up and down.

Each of the guide plates constituting the left and right guide plates 410a and 410b; 420a and 420b is formed in the same size and the same shape having a rectangular shape of a predetermined thickness. Small, medium, and large through holes 422, 423, and 424 are formed so that the first, second, and third rollers of size are fitted, and another guide plate 410a, 410b; U-shaped openings 421 are formed to exclude interference with the small, medium, and large rollers coupled to the 420b.

In addition, a cylindrical groove 240 is formed in the center between the guide grooves 210 of the second body 200 so as to exclude interference with the wedge of the pressing hole 300, and the upper and lower portions of the cylindrical groove 240 The upper and lower inclined surfaces 220a and 220b are formed symmetrically ((X-axis symmetry) with respect to the transverse direction, that is, the second body 200 is engaged forward by engaging the upper and lower second rollers 430b and 440b). When viewed from the side, the upper and lower inclined surfaces 220a and 220b are curved to gradually increase from the cylindrical groove 240 to the upper and lower portions (from the center to the radially outer side) and toward the first body 100.

The fixed pressure increasing device for the vise of the present invention configured as described above is coupled to the first port 100 to the pressure port 300, and then the upper and lower wheels to the left and right guide plates (410a, 410b; 420a, 420b) The lower first to third rollers 430a, 440a; 430b, 440b; 430c, 440c are rotatably coupled to each other so that the upper guide grooves 110 and 210 of the first body 100 and the second body 200 are rotated. To be guided downward.

 Then, the bolt hole 120 of the first body 100 and the screw hole 230 of the second body 200 are fastened and fixed by bolts 510 coupled with the spring 520.
