Abstract

The present invention discloses a multi-position precision determination device using the spring force of the spring. The V-shaped protruding member of the positioning projection is coupled to the V-shaped groove of the positioning plate by the elastic force of the spring. In the case of the aging process of the multi-tube cathode tube, in which the socket of the cathode-ray tube must be replaced according to the tube type, one socket is coaxial with the electron gun base by attaching a positioning protrusion and a positioning plate to the left and right sliders to which the multi-tube sockets are fixed and the slider support member. The location can be precisely determined to be in the phase. Accordingly, socket replacement is unnecessary, and it is possible to automate the aging process and similar processes in the multi-tube longitudinal cathode ray tube.

The present invention relates to a multi-position precision determination device, and more particularly, to a multi-position precision determination device of a multi-tube longitudinal cathode ray tube socket.

Generally, as shown in the drawing in a process such as an aging process for activating a cathode ray tube by popularizing a voltage in an electron gun after the tipping operation of the vacuum tube and the electron gun stem portion of the cathode ray tube. After loading the cathode ray tube 1 into the card, the socket 3 is lifted up and inserted into the electron gun base 2 so that a voltage can be applied. That is, the socket 3 is connected to the frame 4 by means of an air cylinder (not shown), etc. with the upper and lower sliders 6 in which the socket 3 is fixed via the fixing means 7 via the ball flanger 5. The socket 3 is attached to and detached from the electron gun base 2 by vertically reciprocating between mounting and detaching positions of the electron gun.

However, the above-described conventional mounting and demounting device has a hassle to replace the socket (3) in accordance with the tube type of the cathode ray tube.

In view of such a conventional problem, the present invention provides a positioning device capable of easily and precisely determining a position, and in particular, to provide a multi-position precision determining device for automating the socket replacement of a multi-tube type cathode ray tube. will be.

In order to achieve the above object, the present invention provides a positioning plate formed with a plurality of V-shaped grooves in a predetermined position; and a projecting member in the body and any one of the plurality of V-shaped grooves embedded in the body and applying elastic force to the protruding member. And a protruding member which is protruded out of the body and guides into the body against the elastic force of the spring and is movable to another V-shaped groove by side force projecting out of the body and applied in a direction perpendicular to the central axis of the plurality of V-shaped grooves It provides a multi-position precision positioning device comprising a positioning projection having a.

In addition, the present invention, the upper and lower sliders to which the above-mentioned positioning plate is fixedly attached; the left and right slider support members fixedly attached at right angles to the upper and lower sliders; the left and right slider support members are movable, and the positioning projections are movable Left and right sliders, which are attached to be inserted into any one of the V grooves of the plurality of V grooves, and the predetermined left and right sliders are fixed on the centerlines of the predetermined plurality of V grooves; An actuator provided in the left and right slider support members is further provided to transmit power to the left and right sliders for moving. It is preferable that the above-mentioned actuator is a step motor or an air cylinder.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 2 to 3.

First, in FIGS. 3A and 3B, the multi-position precision positioning device 20 includes a positioning plate 25, a body 23, a spring 22, and a protruding member having a V-shaped groove formed at predetermined positions. It consists of a positioning projection 20 having a 21). The protruding member 21 is pressed outward by the spring 22 to be moved inward in the body 23, and the couple protruding out of the body 23 is coupled to the V-shaped groove of the positioning plate 25 described above. Is formed.

The body 23 may be formed by being separated into the stopper 23a, the spring support plate 23b, and the upper and lower bodies 23c of the protruding member 21, and may remove components according to the structure of the part to be installed. In FIG. 3 (a) (b), the upper body 23c is used in a removed state.

2 shows a multi-position precision determination device as a socket for a multi-tube type cathode ray tube to which the multi-position precision determination device 20 according to an embodiment of the present invention of the drawing is applied.

The left and right slider support members 11 in FIGS. 2A and 2B and the left and right slider support members 11 are movable so as to be movable in the left and right directions shown by arrows in FIG. Any one of the plurality of sockets 3a, 3b, 3c via the slider 13 is coaxial with the electron gun of FIG. The left and right slider support members 11 are fixed to the upper and lower sliders 6 and vertically reciprocate between the mounting and dismounting positions of the socket.

The positioning plate 25 of the positioning device 20 of FIG. 3 described above is fixed to the upper and lower sliders 6, and the positioning projections 21 are coupled to any one of the plurality of V grooves of the positioning plate 25. It is fixed to the left and right sliders 3 as much as possible.

The left and right sliders 13 are provided with a plurality of multi-tubular sockets 3a, 3b, and 3c at positions corresponding to each of the plurality of V-grooves through the fixing means 7.

The left and right sliders 3 are guided and supported on the left and right slider support members 11 by sliding or rolling contact means such as the ball flanger 12.

The left and right sliders 13 move between each of the plurality of V groove positions by an air cylinder or step motor 30 fixed to the left and right slider support members 11, and the protruding member 24 and each V groove ( 26) the position is precisely determined.

Therefore, as an example of the method of assembling the above-mentioned parts, it is precise to position the socket fixing means 7 on the left and right sliders 13 after mounting the socket to the electron gun base 2 at the position of each V groove. It would be desirable to determine.

Operation according to the configuration of the embodiment of the present invention described above is as follows.

If the socket 3a is to be used when the socket 3b is coaxial with the electron gun base 2, the air cylinder or the step motor 30 is operated to protrude the left and right sliders 11 in FIG. The member 24 is moved to the position to be inserted into the V-shaped groove 26 on the right side. At this time, the projecting member 24 moves to the body 23 by the action of the V groove against the elastic force of the spring 22 by the power of the air cylinder or the step motor 30 to the position of the right V groove. At the position of the V groove on the right side, the protruding member 24 protrudes again by the elastic force of the spring 22 and engages with the V groove, whereby the socket 3a is coaxial with the electron gun base 2. It will be finely moved into position.

In the case of the above-described air cylinder, it can generally be used for two positioning, but in the case of three or more positions, a step motor is preferable.

This configuration allows the present invention to precisely determine the multi-position precisely, to eliminate the replacement of parts according to the type of the tube, such as socket, and provides the effect of enabling the automation of the multi-pipe.

In the above, an example in which the multi-position precision determining device according to an embodiment of the present invention is applied to a multi-tubular socket mounting and detaching device has been described. However, when the multi-position precision determining device is applied to other devices that must accurately determine the multi-position, Application would be possible.
