[Industrial applications]

 TECHNICAL FIELD The present invention relates to a work table for mold processing used when further finishing a machined mold by manual work.

[0002]

[Prior Art]

 Conventionally, in the processing of molds, a work is performed by a predetermined machine such as a machining center or a laser processing machine based on a design drawing, and then a highly skilled worker manually finishes the work. This finishing process includes machining and correction of the shape by filing, deburring of minute parts with an oil grindstone, polishing with a polishing cloth, or mirror finishing with lapping. We also use electric grinders to polish and finish. In such finishing work, the work is carried out by using a square bar or the like and placing the die on a work table so that the die has a predetermined inclination angle.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, since the die is tilted by a square material or the like for finishing, the tilt angle of the die cannot be freely adjusted. Therefore, it is necessary to change the position and direction of the mold by lifting it, which causes a problem of low work efficiency such as a back pain for the worker.

An object of the present invention is to solve the above-mentioned problems and to provide a workbench for mold processing in which the position and direction of the mold can be easily adjusted.

[0005]

[Means for Solving the Problems]

 The working table for mold processing of the present invention is provided with a pillar standing upright on the base, a horizontal rotary spindle having a base end fixed to the upper part of the pillar, and a tip of the rotary spindle. A mold mounting plate on which the mold is mounted, a first guide roller which is orthogonal to the axis of the rotary support shaft and is provided on the radial upper surface of the mold mounting plate, and the mold mounting plate. Second guide rollers provided on the upper surface and on both sides of the first guide roller are provided.

In addition, a stopper is provided movably on the upper surface of the base so that the lower surface of the die mounting plate can be locked, and further, a worm wheel fixed to the rotation spindle and the worm wheel. It is equipped with a worm gear driven by a handle that is screwed together.

[0007]

[Action]

 With the above configuration, when the die is placed on the die mounting plate, the inclination angle of the die can be adjusted by the angle of the rotation support shaft, and the outer circumference of the die is brought into contact with the first and second guide rollers. The mold can be easily rotated by touching it. Further, when the die mounting plate rotates during work, etc., the die mounting plate is locked by the stopper to prevent the rotation, and the safety can be improved. Further, by rotating the handle, the rotation spindle can be rotated to easily adjust the inclination angle of the die mounting plate.

【Example】

 Next, a first embodiment of the present invention will be described with reference to FIGS. A prismatic pillar 2 is erected on one side of the base 1, and a mounting hole 3 is horizontally provided on the pillar 2. A base end 5 of a rotary support shaft 4 is rotatably inserted into the mounting hole 3, and a groove 6 is provided on the outer periphery of the base end 5. Then, a bolt 7 whose tip is pressed against the groove 6 is screwed from the upper surface of the column 2. One end of a die mounting plate 10 on which a short cylindrical die 8 is placed is fixedly attached to the tip 9 of the rotary support shaft 4. The die mounting plate 10 has a disk shape, and one side of the die mounting plate 10 is placed on the tip 9 and is fixed by a bolt 11. Further, a through hole 12 is formed slightly eccentric from the center of the die mounting plate 10. Further, the mold mounting plate 10 is provided with a pair of left and right first guide rollers 13, and second guide rollers 14 are provided on both sides of the first guide roller 13. The first guide roller 13 is provided on the upper surface in the radial direction of the die mounting plate 10 facing the axis X of the rotary support shaft 4, and the first guide roller 13 of the bifurcated mounting member 15 is provided. It is rotatably installed at the tip. Further, the bifurcated mounting member 15 is mounted on the upper surface of an L-shaped mounting member 16 mounted on the outer periphery of the mold mounting plate 10. For this attachment, a long hole 17 is formed in the bifurcated mounting member 15, and the bifurcated mounting member in which the first guide roller 13 is mounted by the bolt 18 which is fixed to the upper surface of the L-shaped mounting member 16 through the long hole 17. The member 15 can be fixed by protruding by a predetermined length. Further, a long hole 19 is also formed in the lower portion of the L-shaped mounting member 16. A forked mounting member 15 to which the first guide roller 13 is attached can be fixed to the die mounting plate 10 by a predetermined height by a bolt 20 which is fixed to the outer periphery of the die mounting plate 10 through the elongated hole 19. It is like this. Further, the shaft portion 14A of the second guide roller 14 slidably penetrates through a long hole 21 formed toward the center of the die mounting plate 10, and its tip is fixed by a nut 14B.

An L-shaped stopper 22 is provided on the upper surface of the base 1, and an elongated hole 23 is formed in the lower portion of the stopper 22. A bolt 24 penetrating the elongated hole 23 is a base. The die mounting plate 10 can be locked by fixing it to the mold 1 and fixing the stopper 22 at a predetermined position. Further, a stopper 25 projects from the rotary support shaft 4, and lower and upper stopper receiving pins 26, 26A capable of being locked to the stopper 25 are provided on the support column 2. The lower stopper receiving pin 26 is provided at a position that locks the stopper 25 when the die mounting plate 10 is rotated in a substantially vertical state, and the upper stopper receiving pin 26A is inverted from the die mounting plate 10. It is provided at a position where the stopper 25 is sometimes locked.

Next, the operation of the above configuration will be described. When the mold mounting plate 10 is tilted in advance so that the mold 8 has a desired angle and the bolts 7 are tightened, the rotary support shaft 4 is fixed and the mold mounting plate 10 is fixed. Next, the die 8 is placed on the upper surface of the die mounting plate 10, and the positions of the first guide roller 13 and the second guide roller 14 are adjusted so that the outer periphery of the die 8 contacts. That is, after loosening the bolt 20 so as to contact the upper outer periphery of the mold 8 and adjusting the height of the L-shaped mounting member 16, the bolt 20 is tightened, and then the bolt 18 is loosened to a predetermined length of the bifurcated mounting member 15. After adjusting the height, tighten the bolt 18. On the other hand, the second guide roller 14 loosens the nut 14B, adjusts the position of the second guide roller 14, and then tightens the nut 14B. Further, the bolt 24 is loosened and the stopper 22 is moved so as to contact the lower surface of the die mounting plate 10, and then the bolt 24 is tightened and fixed. When the die 8 is placed on the inclined die mounting plate 10 in this manner, the die 8 is supported by the first and second guide rollers 13 and 14, and the die 8 is used for finishing. When the direction is changed while being rotated, the upper part of the outer periphery of the mold 8 is guided while being supported by the first guide roller 13, and the lower part of the outer periphery of the mold 8 is guided while being supported by the second guide roller 14. Therefore, the mold 8 is supported at four points and can be smoothly rotated while contacting. At this time, even if the bolt 7 is loosened, the rotation of the mold mounting plate 10 is locked by the stopper 22 and the mold 8 does not drop. During storage, the bolt 7 is loosened and the die mounting plate 10 is set in a substantially vertical state so that the stopper pin 25 is locked to the lower stopper receiving pin 26.

As described above, in the above-described embodiment, the mold 8 is placed on the tip 9 of the horizontal rotary support shaft 4 which is fixedly provided on the upper portion of the column 2 which is erected on the base 1. The die mounting plate 10 is attached, and a first guide roller 13 is provided in the radial direction of the die mounting plate 10 orthogonal to the axis X of the rotary support shaft 4. By providing the second guide rollers 14 on both sides, the die mounting plate 10 is inclined to incline the die 8 to a desired angle, and the first guide roller 13 and the second guide roller 14 are further inclined. Are arranged in an arc shape along the outer periphery of the die 8, and the die 8 can be smoothly rotated by guiding the die 8 while being in contact with the first guide roller 13 and the second guide roller 14. Can be done at any time. Further, since the height of the first guide roller 13 can be adjusted, the height of the mold 8 can be accommodated.

Further, by providing the position-adjustable stopper 22 on the base 1, even if the bolt 7 is loosened, the mold 8 is not likely to drop and the safety is excellent.

FIG. 4 shows a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, the other end of the rotary support shaft 4 is projected from the column 2, a worm wheel 31 is fixed to this projection, and a worm 32 screwed to the worm wheel 31 is longitudinally arranged. It is provided. A handle shaft 33 is connected to the worm 32. The handle shaft 33 penetrates a mounting member 34 provided horizontally on the upper portion of the support column 2 and a handle 35 that rotates horizontally is provided at the upper end of the handle shaft 33. It is connected.

Therefore, when the handle 35 is rotated to one side, the rotation is transmitted to the worm wheel 31 via the worm 32, and the die mounting plate 10 is tilted via the rotation support shaft 4 and the worm wheel 31 is rotated. The inclined state is maintained by the engagement between the tooth portion of the worm and the tooth portion of the worm 32. In this way, the worm wheel 31 is provided on the rotary support shaft 4, and the worm 32 screwed onto the worm wheel 31 is connected to the handle 35, so that the handle 35 is rotated and the mold mounting plate 10 is moved. Even if the mold mounting plate 10 is tilted and the hand is released from the handle 35, the mold mounting plate 10 can be held in a tilted state, and operability can be improved. The present invention is not limited to the above-described embodiment, and for example, only one first guide roller 13 is attached to the die mounting plate via the mounting member, and the first guide roller and the second guide roller 13 are attached. Various modifications are possible such that the mold can be rotated by three-point support by a guide roller.
