Description

  The present invention relates to a surface plate used for placing a height gauge, and more particularly to a surface plate and a height gauge formed so as to improve usability.

  Conventionally, this type of surface plate is formed into a flat base plate shape with a smooth upper surface. In addition, as described in Patent Document 1, for example, a height gauge used on the surface plate is configured such that a guide member is vertically set on a pedestal portion made of a metal material such as iron, and this guide member The slider is provided so as to be movable up and down, and a probe is attached to the slider.

When measuring the height of machine parts, etc., place the height gauge and the measurement object (measurement object) on the surface plate, lower the height gauge slider, and place the probe on the top surface of the measurement object. This is done by reading the value.
Further, when performing the marking work, the workpiece is placed on the surface plate and, for example, the workpiece is slid on the surface plate in a state where the height gauge is pressed and fixed by hand.

  Thus, during this type of work, for example, if the height gauge can be temporarily fixed to the surface plate, the height gauge or the like can be prevented from being displaced or overturned, and the usability is improved. In addition, it is not necessary to hold the height gauge firmly by hand during the marking work, so the work can be performed easily and accurately.

  Therefore, it is desirable that the surface plate and the height gauge be formed so that the surface plate can be temporarily fixed to the height gauge and the height gauge can be temporarily fixed to the surface plate according to the type and contents of work.

  However, the conventional surface plate is merely formed in the shape of a flat base plate, and the conventional height gauge can only be used on the surface plate and has no function of fixing the height gauge. .

  Thus, the object of the present invention can also be achieved by providing the height gauge 1 with the suction device 4 instead of providing the suction device 4 with the surface plate 2.

  That is, according to the present invention, as shown in FIG. 9 and the like, the height gauge 12 is used by being placed on the surface plate 13, and the pedestal portion 12a of the height gauge 12 placed on the surface plate 13 is in an excited state. The suction device 4 with the switch 3 for switching the demagnetization state is provided, and the switch 3 of the suction device 4 is detachably formed on the surface plate 13 through the pedestal portion 12a by the action of magnetic force. It is characterized (claim 4).

  The magnet of the suction device 4 may be a permanent magnet 7 or an electromagnet as described above. The switch 3 of the suction device 4 is specifically realized by being provided on the side surface or the upper surface of the pedestal portion 12a.

In the surface plate of the present invention, the height gauge can be temporarily fixed to the surface plate by operating the switch of the suction device and exciting in this manner, and the suction of the pedestal portion can be released by demagnetizing.
Therefore, in the case of the present invention, the height gauge can be fixed or unfixed and moved according to the type and content of the work, so that the measurement work can be performed easily and accurately. It has a practically excellent effect that it can be used and is easy to use.

Further, the height gauge of the present invention can be temporarily fixed to the surface plate by switching operation of the suction tool or can perform measurement work by releasing the fixed state.
Therefore, according to this, as in the case of the above-described surface plate, the measurement work and the like can be performed easily and accurately, and the usability is improved.

Further, the product of the present invention is provided with a handle 5 on the front and rear thickness surfaces 2a so that it can be easily carried.

Thus, the suction device 4 is provided so as to bite into the inside of the surface plate 2 from the thickness surface 2 a of the surface plate 2, and the switch 3 protrudes to the side of the surface 2 a of the surface plate 2. Is provided.
Specifically, as shown in FIG. 5, the suction device 4 is fitted and bonded to the recess 6, and is positioned so that the magnetic force acting surface of the upper surface 4 a is flush with the upper surface 2 b of the surface plate 2. Yes. In this embodiment, the recess 6 is formed in a cutout shape at the center of one side of the surface plate 2.

  Further, as shown in FIGS. 6 and 7, the suction device 4 is formed in a block shape with a cylindrical permanent magnet 7 that is slidably rotatable. The permanent magnet 7 is magnetized in the diameter direction. The main body of the suction device 4 that houses the permanent magnet 7 is formed of a pair of left and right magnetic bodies 8 and a nonmagnetic body 9 sandwiched between upper and lower opposing surfaces of the magnetic body 8. The nonmagnetic material 9 is provided over the entire length of the suction device 4 in the front-rear direction.

  In this embodiment, the switch 3 is formed in a knob shape so that it can be turned on and off by rotating left and right. The switch 3 is provided on the outer surface of the adsorption device 4 with the axis of the rotation shaft concentric with the axis of the permanent magnet 7. As shown in FIG. 4 and the like, an ON display indicating the suction side and an OFF display indicating the non-suction side are attached to the outer surface of the suction device 4.

  In the height gauge 1, a rod-shaped guide member 1b is vertically set up on a pedestal portion 1a, and a measuring element 1d is provided on a slider 1c that moves up and down while being guided by the guide member 1b. The slider 1c includes a display unit 1e that digitally displays the measurement value, and is set so that the numerical value of the display unit 1e displays 0 when the measuring element 1d is brought into contact with the upper surface of the pedestal portion 1a.

Next, an example of using the inventive device of this embodiment will be described.
First, the operator places the pedestal portion 1a of the height gauge 1 at the position of the upper surface 4a of the suction device 4 (see the chain line state in FIG. 1). Then, the switch 3 is turned to switch the switch 3 from the OFF display side (see FIGS. 1 and 4) to the ON display side.

  Then, the permanent magnet 7 rotates from the state of FIG. 6 as shown in FIG. 7, and a magnetic flux is generated on the upper surface 4a which is a magnetic force acting surface. As a result, the pedestal portion 1 a is adsorbed and the height gauge 1 is fixed to the surface plate 2.

In this state, the operator places a machined part 10 (see FIG. 2), for example, a machined part on the surface plate 2 near the pedestal portion 1a, and then lowers the slider 1c to remove the measuring element 1d. The measurement surface is placed on the object to be measured 10, and the height of the object to be measured 10 is measured by reading the numerical value on the display unit 1e of the slider 1c. Further, when performing the marking work, the workpiece 10 is moved on the upper surface 2b of the surface plate 2, and the tip of the probe 1d is used.
In this case, the present invention can also be used in which the measurement object 10 is placed on the upper surface 4a of the suction device 4 and the measurement object 10 is fixed to the surface plate 2 with the suction device 4 to perform measurement work or marking work.

  Thus, when the height gauge 1 is used at an arbitrary position on the surface plate 2, the switch 3 is turned to the OFF display side. Then, the N pole and the S pole of the permanent magnet 7 are arranged vertically from the horizontal state (see the state in FIG. 7) as shown in FIG. As a result, as shown in the figure, the magnetic flux is generated in a closed loop shape in the permanent magnet 7 and the magnetic body 8, and the magnetic field on the upper surface 4a of the adsorption device 4 disappears. As a result, the suction state of the pedestal portion 1a is released and the bite gauge can be moved.

FIG. The switch 3 may be provided so as to be exposed on the surface plate 2. Moreover, the adsorption | suction instrument 4 may incorporate the electromagnet, and may be formed so that an excitation state and a demagnetization state can be switched electrically. In this case, the switch 3 can be provided at a position where it can be easily moved away from the suction device 4.

In the above example, the upper surface 4a, which is the magnetically acting surface of the suction device 4, is exposed on the upper surface 2b of the surface plate 2, but the present invention is not limited to this.
That is, in the present invention, as shown in FIG. 8, the upper surface 2b of the surface plate 2 is formed of a magnetic material such as an iron plate, and the magnetic force acts on the pedestal portion 1a via the upper surface 2b. It may be provided on the lower side. In this case, in order to make the location of the suction device 4 easy to understand, a display 11 representing the suction location is provided in a planar manner by means of printing or the like at the position of the upper surface 2b of the surface plate 2 corresponding to the suction device 4. Is good.

  Next, a preferred embodiment of the height gauge 12 (see FIGS. 9 and 10) of the present invention will be described with reference to the drawings. The same portions and the same members as those in the above example are denoted by the same reference numerals, and detailed description thereof is omitted.

  The height gauge 12 of the present invention is used by being placed on a surface plate 13, and a pedestal portion 12a placed on the surface plate 13 includes an adsorption device 4 with a switch 3 for switching between an excited state and a demagnetized state. By the switching operation of the switch 3 of the suction device 4, the surface plate 13 is detachably formed by the action of magnetic force through the pedestal portion 12a.

  Further, the suction device 4 is configured in the same manner as in the above example. The switch 3 of the suction device 4 is provided on the side surface of the pedestal portion 12a so as to be exposed.

Next, an example of using the inventive device of this embodiment will be described.
First, the operator places the height gauge 12 at an arbitrary position on the surface plate 13 (see the state of FIG. 9). Then, the switch 3 of the suction device 4 is turned to switch the switch 3 from the OFF display side to the ON display side.

  Then, the permanent magnet 7 rotates from the state shown in FIG. 6 as shown in FIG. 7, and magnetic flux is generated on the upper and lower magnetic force acting surfaces of the attracting device 4. Thereby, the pedestal portion 12 a of the height gauge 12 is attracted to the upper surface 13 a of the surface plate 13 by the magnetic force on the lower surface side (bottom surface side) of the suction device 4, and the height gauge 12 is fixed to the surface plate 13.

  In this state, the operator places, for example, a machined part that is the workpiece 10 on the upper surface 13a of the surface plate 13 near the pedestal portion 12a, and lowers the slider 1c to place the measuring surface of the probe 1d on the workpiece. 10 (see the state of FIG. 2), the numerical value of the display unit 1e of the slider 1c is read to measure the height of the object 10 to be measured. Further, when performing the marking work, the workpiece 10 is moved on the upper surface 13a of the surface plate 13, and the tip of the probe 1d is used.

  When the height gauge 12 is used at an arbitrary position on the surface plate 13, the switch 3 is turned to the OFF display side. Then, the N pole and the S pole of the permanent magnet 7 are arranged vertically from the horizontal state (see the state in FIG. 7) as shown in FIG. As a result, the magnetic flux is generated in a closed loop shape in the permanent magnet 7 and the magnetic body 8 as shown in the figure, and the magnetic fields on the upper and lower magnetic force acting surfaces of the suction device 4 disappear. As a result, the suction state of the pedestal portion 12a is released, and the bite gauge can be moved.
