[Industrial applications]

 The present invention relates to a copying apparatus, and more particularly to a new improvement for correcting the copying mechanism balance of a copying needle used in the field of welding and the like.

[0002]

[Prior art]

 As a copying apparatus of this type that has been conventionally used, generally, a copying needle provided at one end of an oscillating linearly reciprocating movable body moves a workpiece above a copying object according to the movement of the moving body. It was configured to follow suit.

[0003]

[Problems to be solved by the device]

 Since the conventional copying apparatus is configured as described above, there are the following problems. That is, as the scanning needle moves with the moving body, the balance of the weight of the scanning needle is lost, and the scanning pressure fluctuates, so that the accuracy of the scanning operation may decrease.

The present invention has been made to solve the above problems, and in particular, it is an object of the present invention to provide a copying apparatus for correcting the copying mechanism balance of a copying needle used in the field of welding and the like. And

 A copying apparatus according to the present invention comprises a table having a rocking center and swingably provided, and a movable body provided on the table so as to be linearly reciprocally movable and having a copying needle at one end. In a copying apparatus configured to copy on a copy object that is a work, a potentiometer provided in a reciprocating drive unit that reciprocates the moving body, a pneumatic cylinder for urging one end of the table from below, A potentiometer and an electropneumatic valve connected to the pneumatic cylinder, and the electropneumatic valve controls the copying pressure of the copying needle via the pneumatic cylinder.

A copying apparatus according to the present invention comprises a table having a rocking center and swingably provided, and a moving body provided on the table so as to be linearly reciprocally movable and having a copying needle at one end thereof. In a copying apparatus in which the copying needle makes a copy on a copying object which is a work, a reciprocating drive unit that reciprocates the moving body, and a micro switch for detecting the position of a step dog provided on the moving body. Group, a pneumatic cylinder for urging one end of the base from below, and an electropneumatic valve connected to the microswitch group and the pneumatic cylinder. The scanning pressure of the scanning needle is controlled via the pneumatic cylinder.

[0007]

[Action]

 In the copying apparatus according to the present invention, the electric signal connected to the pneumatic cylinder is output by the output signal of the micro switch group that detects the movement of the potentiometer or step dog that moves in conjunction with the movement of the moving body having the copying needle. By controlling the expression valve, the pressure of the pneumatic cylinder that urges one end of the base from below is controlled, and as a result, the copying pressure can be controlled in conjunction with the position of the copying needle.

【Example】

 Hereinafter, preferred embodiments of a copying apparatus according to the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a base provided on the base 2 so as to be swingable about a swing center 4 via a shaft support portion 3. The slide portion 1a on the base 1 has one end A moving body 6 having a copying needle 5 and which is linearly reciprocally movable in the direction of arrow A is provided.

The copying needle 5 is provided with a proper contact pressure with respect to the copying object 7 so as to be able to copy over the copying object 7 which is a work, and is provided on the base portion 2. The protrusion 8a of the pressure cylinder 8 urges the lower part of one end of the base 1 upward.

An electro-pneumatic valve 9 is connected to the pneumatic cylinder 8, and the electro-pneumatic valve 9 controls the biasing force of the protrusion 8 a of the pneumatic cylinder 8. A voltage value of a potentiometer 13 that is interlocked with a reciprocating drive unit 12 including a motor that drives a pinion 11 that meshes with a rack 10 formed on the movable body 6 is input to the electropneumatic valve 9 as a control signal 13a. As a result, the pneumatic cylinder 8 is controlled.

Further, in another embodiment shown in FIGS. 2 and 3, instead of the potentiometer 13 described above, a step dog 20 provided on the moving body 6 is used, and the step dog 20 is By operating the buttons 30a to 30e of the micro switch group 30 in which the stairs 20a are fixedly arranged, as shown in FIG. 3, five series switches connected to the micro switches LS1 to LS5 of the micro switch group 30 are connected. The electropneumatic valve 9 is controlled by controlling the presence or absence of a short circuit in each of the resistors R1 to R5. Therefore, the movement of the staircase dog 20 (that is, the movement of the moving body 6) controls the biasing force due to the protrusion of the protrusion 8a of the pneumatic cylinder 8 in the same manner as described above, so that the tracing needle 5 is moved. The scanning pressure due to the movement can be optimally controlled.

[0012]

[Effect of device]

 Since the copying apparatus according to the present invention is configured as described above, the following effects can be obtained. In other words, the pneumatic cylinder controls the biasing of one end of the platform that has the movable body swingable in response to the movement of the copying needle, so that the balance of the copying mechanism that occurs with the movement of the copying needle is prevented from collapsing. Therefore, it is possible to obtain a smooth contact of the copying needle regardless of the moving position.
