Abstract

PURPOSE:To reduce an error in adhesion between a reference plane and a product to stabilize machining accuracy by improving adhesion between a workpiece and a jig as the jig ascends, or when the jig stops temporarily or moves upward. CONSTITUTION:A product carrying in guide is fixed onto a base attached to a main body 6 to supply a product 1. Next a jig 2 moves to a lower end to transfer the product 1 onto the V-groove of the jig 2 by a pushing out rod. A slide unit to which a compression coil spring is attached is advanced by a driving wire to abut the end face of the coil spring against the reference plane of a hard material 5 attached to the main body 6. The jig 2 ascends to bring the side of the coil spring into contact with the product for making the product 1 precisely adhere to the V-groove of the jig 2, which stops at this position. Since when the coil spring moves back as it is, the product 1 adhering to the V-groove falls down, after a pressing plate advances to fix the product 1, the coil spring moves back.

Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY In the processing of minute parts such as magnetic heads, it can be used as an automatic supply device for groove processing and cutting processing.

Conventional technology Grooving and cutting in the processing of magnetic heads etc. are products that are minute and mainly planar, so first of all, a high precision jig is used to suppress the adhesive and physical force. To fix. Next, the jig to which the product was fixed was accurately fixed to the standard of the processing machine before processing. (Since the cylindrical parts have a cylindrical surface or center processing, it is easy to obtain a fixed reference and it is easy to design a rolling type supply / discharge device that uses the cylindrical surface. As you can see, the accuracy of the fixation must be confirmed each time by requiring the fixation twice. Further, when the fixing and the inspection are performed by a human, the quality and efficiency depend on the ability of the operator, and for automation, image processing and the like are used, which is an expensive facility.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention has been invented for the purpose of compensating for the above-mentioned two-time fixing defect and being attachable to a commercially available general-purpose machine, being inexpensive, highly accurate and highly efficient.

Means for Solving the Problem First, the operation system will be described with reference to FIG.
After fixing the wear-resistant hard material 5 to, the reference surface 31 and the slide groove 32 are processed, and the vertical movement jig 2 is attached. The jig 2 is connected to the driving device 9 by the joint 8. The vertical stop position of the jig 2 is determined by the stroke groove 7 and the pin 3, and the solid line is the product processing position when moving upward, and the broken line is the product supply position when moving downward. Next, a description will be given using an example of an apparatus using this system, which is shown in FIG.
FIG. 2 is a side view and FIG. 3 is a top view of the apparatus in which necessary parts are attached. Referring to FIGS. 2 and 3, the product carry-in guide 15 shown in FIG. 4 is fixed on the base 17 attached to the main body 6 to supply the product 14.
Next, the jig 2 moves to the lower side, and the extrusion rod 16 is used to move the product 1
4 is placed on the V groove of the jig 2. Compression coil spring 1
9 is attached to the slide unit 11 drive wire 1
The end surface of the coil spring 19 is abutted against the reference surface of the hard material 5 which is advanced by 3 and attached to the main body. The jig 2 rises and the side surface of the coil spring 19 comes into contact with the product, so that the product accurately adheres to the V groove of the jig 2. Further, when the jig 2 is stopped at this position and the coil spring 19 is retracted as it is, the product in close contact with the V-shaped groove is collapsed, so that the pressing plate 24 is advanced to fix the product and then the coil spring 19 is retracted. Next, press plate 24
Will retreat. Explaining in order, the jig 2 moves to the processing position. The clamp pin 21 moves forward to fix the product 1. The spindle 27 of FIG. 2 descends and the product 22 is processed by the tool 22. The main spindle 27 moves up. The clamp pin 21 discharges the fluid from the retreat nozzle 20. Discharge pin 2
6 advances to push the product 1 out of the V groove of the jig 2. The extruded product 1 is distributed to the left and right discharge guides 28 by the fluid discharged from the nozzle 20, and discharged on the fluid. The jig 2 descends and a series of operations are repeated to perform processing.

EXAMPLE AND EFFECT In the groove processing of the composite type core slider housing of the magnetic head for a fixed disk shown in FIG. 5, when the apparatus described in FIGS. Individual products can be processed simultaneously. The size of the main body 6 is 160 mm in height, 150 mm in width,
The depth can be suppressed to 80 mm and it can be mounted on a general-purpose slicing machine. The main effects are as follows.

1) There is no longer the time loss of the work of fixing the product twice and confirming it with a microscope, and the jig attachment / detachment.

2) Since the conventional processing method shown in FIG. 6 was changed to the processing method shown in FIG. 7, the loss time of the processing time was greatly reduced.

3) Highly accurate and expensive jigs, which were required in the past, are no longer required.

4) In the past, many jigs and the accuracy control of the jig attachment standard of the processing machine were frequently performed, but since the same place is used for the processing reference plane, the accuracy management has almost disappeared.

5) Since the processing reference surface always removes foreign matter while the product moves, the adhesion error between the reference surface and the product is reduced and the processing accuracy is stable.

6) The efficiency per worker was 5.1 times that of the conventional method, and the efficiency per machine was 2.1 times.
