Description

Description Work clamping method by vice device and vice device

Technical field

The present invention relates to, for example, a method for clamping a work by a vice device used in a cutting machine and a vice device, and more particularly, for example, to a pipe material. In particular, the present invention relates to a clamping method and a device for clamping a work piece with an appropriate clamping force without crushing the work piece. Background art

Conventionally, when a workpiece is cut by a cutting machine equipped with an appropriate cutting blade, a reference vise jog provided in a main body vise device arranged close to the cutting position. The work is clamped and fixed by the moving bijou. In addition, in order to automatically cut a long work for each predetermined dimension, a reciprocating material feeder reciprocates in a direction approaching and moving away from the main body vice device. A work device is set up, and the work is sandwiched by the reference vise and the movable vise provided in this material vise device, and the material is fed in the longitudinal direction. This is being done.

When the work is clamped and fixed in the main body vice device and the feeding vise device, when the work is a pipe material etc., the clamping force is large. The work may be crushed.

If the clamping force is small, for example, When a workpiece is sandwiched between the workpieces and the material is to be transported, relative slippage occurs between the workpiece and the transporting device, resulting in high accuracy. It may not be possible to perform the material feeding function.

Therefore, as shown in FIG. 4, the reference viscometer 103 provided in the Israeli 101 and the reference viscometer 103 are provided. In a noise device that clamps and fixes the work W by its own moving vice holder 105, it moves in the direction in which the moving vise approaches and moves away from the moving vise. A configuration in which a pressure control valve 1 11 is arranged in a hydraulic circuit 1 09 of a hydraulic cylinder 1 07 for reciprocating a joe 105 has been developed. Yes.

In addition, as shown in Fig. 5, the position is adjusted to the piston-piston rod 11-15 internally reciprocatingly reciprocating in the hydraulic cylinder 113. A rack 1 19 is provided on the adjustment rod 1 17 which is screwed as much as possible, and an engaging claw 1 2 1 which can be disengaged is mounted on this rack 1 19, and the movable jaw 1 The configuration of the configuration set in 05 is developed and reviewed.

In the conventional configuration shown in FIG. 4, since the pressure of the hydraulic cylinder 107 can be controlled by the pressure control valve 111, the work Even if W is an easily deformable work piece of pipe material, it can prevent crushing. However, in the above configuration, when the clamping force S is small due to the reference bias joint 103 and the moving noise joint 105, the position is small. It has the potential to cause relative slip when performing the work of feeding the work W.

That is, in the above configuration, the material and shape of the work W Adjust the clamping force to an appropriate value so that plastic deformation of the work w does not occur depending on the condition, and no slip occurs during the feeding operation. There is a problem that is bothersome.

In addition, in the configuration shown in FIG. 5, the piston in the hydraulic cylinder 113 and the piston rod 131 in the hydraulic cylinder 113 are used. The movable claw length is short, and the movable vise holder 105 is configured to reciprocate within a predetermined small range, so the engaging claw provided on the movable vise holder 105 is provided. Adjust the engagement position between 1 2 1 and the rack 1 1 9, and rotate the knob 1 and 2 3 provided on the hydraulic cylinder 1 13 to rotate the rack 1 By adjusting the position of the reciprocating area of 19 in the left and right direction as shown in the figure, the reciprocating movement of the moving joint 105 according to the width dimension of the mark W The position is adjusted, and the work W can be clamped without causing plastic deformation.

However, in the above configuration, when the width of the work W is greatly changed, the engaging claw 122 provided on the movable bypass 105 is provided. The position of engagement with the rack 1 19 is readjusted in accordance with the width of the work W, and the handle 1 2 3 is rotated to operate the rack 11 1 It is necessary to readjust the position of the movement area 9 in the horizontal direction in the figure. In other words, there is a problem that it is troublesome to adjust the position of the moving area of the moving blind 105.

Accordingly, the present invention has been made in view of the above-described conventional problems, and its purpose is to prevent the work from being plastically deformed. Can hold the mark, and An object of the present invention is to provide a work clamping method and a device for easily adjusting the position of a movement area of an issue. Disclosure of invention

According to the first aspect of the present invention, a work clamping method using an issu device is based on a reference vise holder provided on a vice bed and a corresponding vice standard.

The accessible position of the moving bijoss with respect to the distance between the reference bijoss and the moving bijoss is slightly smaller than the width of the work. At a predetermined position, the moving vise is brought closer to the reference vise and brought into contact with the jig, and the moving vice is renewed. By moving to the set position at the time, the reference A work clamping method using a vice device, characterized in that the work is clamped between them.

Further, the work clamping method by the device based on the second aspect of the present invention is based on the device based on the first aspect described above. In the work clamping method, the position at which the distance between the reference bisecting piece and the moving bisecting piece is slightly smaller than the width dimension of the work piece is as follows. The work clamped by the reference and moving bijoss shall be clamped in a state where elastic deformation is imparted but plastic deformation is not performed. It is characterized by As described above, the reference vise provided on the vise bed and the self-moving vise moving in the direction approaching or moving away from the reference vise. In the method for clamping a workpiece by the above-mentioned device for clamping a workpiece by a unit, the approach of a moving bi-junction to the reference bi-unit is described. The possible position is set in advance to a position where the distance between the above-mentioned reference and first movements is slightly smaller than the width of the work. The work clamp is moved by the moving device to the reference position, and the work clamp is held between the reference device and the work clamp. The method is a method that applies plastic deformation even to a force that does not give the work a `` plastic deformation ''. The work can be clamped and fixed by the reference noise and the movement noise.

In this case, set the movement position of the movement holder to a position slightly smaller than the width of the work to be clamped and fixed, and set the movement holder as described above. Since it is good to move to the set position, it is necessary to hold the work with an appropriate holding force without giving plastic deformation to the work. It can be easily implemented.

The noise device based on the third aspect of the present invention moves in the direction approaching or moving away from the reference vise on the vise bed. The work piece is sandwiched between the base piece and the above-mentioned reference piece, and the self-moving piece is moved in a vice device equipped with the above-mentioned vise bed. In contact with the abutment part provided in the vice-jos, in front of the moving visa Restriction of movement in one direction of the reference noise holder A configuration in which a self-stopper member is provided so that the position of the stopper member can be adjusted in a direction in which the stopper member approaches or moves away from the reference nozzle. It is.

As described above, the robot moves in the direction approaching and moving away from the reference bistro provided on the noise bed, and works between itself and the above-mentioned reference bistro. In the above-mentioned vice device provided with the own movable vise jog in the above-mentioned vise bed, the movable abutment abuts on the abutting part provided in the above-mentioned movable vise joe. The movement of the movable holder in the one direction of the reference holder; and a method of moving the own stopper member toward and away from the reference holder. The force is a self-contained configuration, and the reference bias and the movable bias are applied without giving plastic deformation while applying elastic deformation to the work. The work can be easily clamped and fixed by the slide. In Ru Oh.

The noise device based on the fourth aspect of the present invention is a vise device based on the third aspect described above, wherein the stopper member comprises: It is movably screwed onto a threaded rod that is long in the direction of movement of the movable vial, and the operation section of the threaded rod is installed on the reference viscous side.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings, in which a vice device according to the present invention is provided at a cutting position in a cutting machine (not shown). A main body vice device that clamps and fixes the work at a close position, and a material vise that carries in and out the long work to and from the cutting position. Force that can be applied to a device such as a device In this example, a case in which the device is applied to a material feeding device will be described.

Referring to FIGS. 1 and 2, the vice device 1 according to the present example corresponds to a reference vise holder 5 provided at the upper end of one end of the noise bed 3. In the direction of approaching and moving away (left and right in Fig. 1) and sandwiching the work W between itself and the reference vise 5 In this configuration, the device 7 is provided on the above-mentioned baybed 3.

The above-mentioned vise bed 3 is supported by a back and forth guide bar 9 provided on a cutting machine (not shown) so as to be able to move back and forth, and the vise bed 3 is provided. The front end of a piston port 13 which moves back and forth in a hydraulic cylinder 11 for back and forth operation provided on a cutting machine is appropriately connected.

Accordingly, the noise device 1 can be moved back and forth along the guide bar 9 by the operation of the fluid pressure cylinder 11, and the reference The work W fixed between the slide 5 and the movable bijo 7 can be fed in the front-rear direction. It is something.

The reference vise 15 is connected to a piston port of a mini cylinder 15 (see FIG. 2) mounted on the vise bead 3. In FIGS. 1 and 2, it is slightly left and right. In other words, when the work W is to be clamped and fixed, the reference bi-joint 15 is controlled by the action of the mini cylinder 15 as shown in FIGS. 2 Moved slightly to the left as shown in the figure and guided by guide bar 9 to return vise bed 3 to its original position (the position before work W started feeding). In this case, the reference vise 5 is configured to be slightly separated from the work W.

Move to the left or right to approach or move away from the reference vise 5 In order to move the vise 7, the opposite side of the mounting position of the reference vise 5 On the upper surface of the vise bed 3, there is provided a slide base 17, which is capable of moving in the left and right direction. Issuer 7 is installed. A left-right guide member 19 (see FIG. 3) is provided on the lower surface of the slide base 17, and the guide member 19 is provided on the side of the vehicle bed 3. The guide support member 21 in the left-right direction provided on the upper surface is moved and supported by itself.

Then, the tip end of the present piston port 23 P is moved in the left-right direction on the vice cylinder 23 appropriately mounted on the vise bed 3. It is appropriately connected to the moving vise 7. Therefore, by moving the piston rod 23P to the left and right by operating the vice cylinder 23 as appropriate, the moving bijos 17 can be moved. It will reciprocate in the left-right direction, approaching and leaving the reference vise-jows 5.

In order to regulate the approach distance of the moving bijou 7 to the reference bijou 5 to be a dimension slightly smaller than the width dimension of 7-kW. In addition, a screw rod 25 that is long in the left-right direction is provided on the vise bed 3 so as to be rotatable, and is screwed into this screw rod 25 in the left-right direction. An abutting portion 29 which can be brought into contact with the stopper member 27 is provided on the lower surface of the slide base 17.

The abutting portion 29 abuts on the stopper member 27 when the movable vice 7 moves close to the reference vice 15. If it is possible, when the moving vice 7 moves in the direction away from the reference vise 5, the abutting part 29 will have a tongue, It is distant from 27. That is, the abutting portion 29 is provided at the position where it abuts and separates from the stop member 27.

The screw rod 25 is supported by the left and right bearings 31 and 33 provided on the vise bed 3 at right and left distances, and is supported by rotation only on its own. It is designed so that it will not move in the axial direction (left / right direction) due to force. A left-right groove 27 G is formed on the upper surface of the stopper member 27 screwed and screwed to the screw rod 25. The groove 27 G is formed in the left-right direction. G has a plurality of bolts on the lower surface of the slide base 17. The fixed lock key 35 long in the left-right direction is relatively engaged with the movement itself.

According to the above configuration, the screw rod 25 is appropriately rotated to appropriately move the stopper member 27 to an appropriate position, and then the movable cylinder 23 is actuated to move. When the vise holder 17 is moved to the reference vise holder 5 side, the abutting part 29 provided on the lower surface of the slide base 17 is attached to the stop member 27. In contact therewith, movement in the direction of the reference visejo 5 is restricted.

A rotation operation section is provided for rotating the screw rod 25. That is, the handle 39 is attached to the bracket 37 attached to the noise bed 3 at a position close to the reference vise holder 5 so that the handle 39 can be rotated by itself. The provided counter device 41 is installed. The counting device 41 counts the forward and reverse rotations of the handle 39 and displays the movement position of the stop member 27 with respect to a reference position. The rotating shaft 43 of the counter device 41 is provided with a self-contained joint 45, a middle shaft 47 and a self-contained joint 49. Thus, it is connected to one end of the screw rod 25.

According to the above-described configuration, when the knob 39 is rotated, the screw rod 25 is rotated in conjunction with the screw 39, and the stopper member 27 screwed to the screw rod 25 is rotated. The left and right movement positions are displayed numerically on the display unit 41A of the counter device 41.

At this point, in FIGS. 1 and 2, the stopper member 27 is moved to the right and the zirconia cylinder 23 is moved. By moving the actuator, the actuator 17 is moved to the reference nozzle 5 side, and the moving actuator 7 directly hits the reference actuator 5. When the stopper member 27 is in contact with the stopper member 27 and the stopper 29 is in contact with the stopper member 27, the position of the stopper member 27 is the reference position. In this case, the display of the counter device 41 at this time ^ 41A is "0".

When the stop 39 is moved forward from the reference position to the left in FIGS. 1 and 2, the handle 39 is rotated forward. The indication on the display section 41A gradually increases as the position of the stopper member 27 is displayed, and conversely, returns the stopper member 27 to the reference position. \ When the handle 39 is rotated in the reverse direction, the numerical value of the display section 41A gradually decreases, and when the tongue member 27 is located at the reference position. It will be "0" again.

In the above-described configuration, when the work W is clamped by the reference nozzle 5 and the transfer nozzle 7, the disk W is solid. In the case where the workpiece is strongly clamped and the plastic deformation does not occur even when the workpiece is strongly clamped, the display unit of the force counter device 41 is used. 4 Set the display of 1 A to “0” and position the stopper member 27 at the reference position, so that the work W of various widths can be freely set. It can be clamped and fixed.

The work W is, for example, a pipe material, and when the work W is strongly clamped and fixed by the reference vise 5 and the moving noise 7, Large plastic deformation occurs in the work W. In such a case, the width of the work W (the diameter in the case of round material) is the position where the tightening amount of the work is subtracted from the width. Rotate the knob 39 so that the member 27 is located, and stop the stopper member 2 according to the indication on the display section 41A on the counting device 41. Check the position of 7. The tightening amount of the work is within a range that gives elastic deformation to the work when the work is clamped and fixed, but does not cause plastic deformation. Work W is the amount that can be deformed.

As described above, by previously setting the stopper member 27 at a position obtained by subtracting the work tightening amount from the width of the work W, the above-mentioned position can be obtained. The accessible position of the movable viscometer 7 with respect to the reference vise 5 is set so that the distance between the reference vise 5 and the movable vise 7 is equal to the work W. It is set in advance at a position slightly smaller than the width dimension, and by moving the moving joystick 7 to this set position, the reference joystick is moved. Work W is sandwiched between -5 and -5. In other words, when the noise cylinder 23 is actuated to move the moving viscometer 7 in the direction of the reference viscometer 5, the moving viscometer 17 and the moving viscometer 7 are actuated. The position immediately before the abutting portion 29 provided on the integral slide base 17 abuts the stop member 27 (when the abutting portion 29 abuts on the stop member 27). When the distance from the part 29 reaches the above-mentioned tightening amount), it comes into contact with the moving bias 7 force work W and the reference noise 5 W ク W is sandwiched between them.

After that, the movement cylinder is activated by the operation of the noise cylinder 23. When the joint 17 is further moved to the reference noise joint 15 side, the work W is elastically deformed, and the abutting portion 29 is set in advance. By contacting the stopper member 27, the movement of the movable bypass 17 to the reference bypass joint 5 side is restricted. As mentioned above. Even if an external force acts to move the stopper member 27, the portion 29 abuts against the member 27, but even if an external force is applied to move the stopper member 27, the screw rod 2 is not affected by the external force. 5 does not rotate, and the screw rod 25 does not move in the axial direction due to the external force. It is possible to reliably restrict the movement of the moving by-jo 17.

As a result, the push W is moved with the reference buy-and-go 15 in a state in which the abutting portion 29 is in contact with the stopper member 27. Between the slider 7 and the slider 7, the elastic deformation is given, but the plastic deformation is not carried out.

Therefore, when the work W is strongly clamped and fixed by the reference noise holder 15 and the moving holder 17, a pipe material that is likely to generate plastic deformation is formed.ゃ Even in the case of a soft material, it can be securely clamped and fixed without causing plastic deformation, for example, a vise for feeding material The work W can be clamped and fixed with an appropriate clamping force so as not to cause relative slip between the device and the work. It is a thing.

In addition, when the work W is clamped and fixed by the above-described reference bijoss 15 and 17 as described above, No., handle 3 of operation unit installed close to quasi-vice 5

By rotating the rotating member 9, the position of the stopper member 27 can be known by reading the display on the display portion 41 A of the counting device 41. Therefore, the position where the dimension slightly smaller than the width of the work W to be clamped and fixed is displayed (subtract the amount of dilution from the width of the work W). It is only necessary to position the stop member 27 at the position shown in the figure) and it is easy to deal with various widths of the work. In addition, it is not necessary to adjust the pressure of the pressurized oil supplied to the viscous cylinder 23, so that the position setting of the movable vice 7 with respect to the reference vice 15 is easy. It is possible to go to

It should be noted that the present invention is not limited to the above-described examples, but can be embodied in other modes by making appropriate changes. For example, the description has been given of a case where the screw rod is rotated by a no-and-handle operation, but a configuration in which the screw rod is rotated using a motor may be used. In addition, the rotation of a screw rod or the like is detected by a rotary encoder, and the rotation is detected based on the output pulse signal of the encoder. However, it is also good to have a configuration that calculates and displays the movement position of the stopper member.

Further, according to the force servo motor illustrated when a vice cylinder is used as a driving device for reciprocating the moving vice. The ball screw is rotated, and a ball nut screwed to this ball screw in a reciprocating motion and a moving nozzle are connected to this ball screw. It is good to have a structure that reciprocates the moving bijou. That is, the present invention can be implemented with various modifications. Industrial applicability

As described above, the peak clamping method and the vise device by the noise device according to the present invention provide a square material or a square material supplied to a cutting machine such as a band saw machine or a circular saw machine. Is useful as a clamping method and a vice device for clamping a material to be cut such as a bar, and in particular, for clamping a pipe-shaped square bar or bar in the air. Suitable for clamping method and device.
