2. Description of the Related Art A conventional work supporting jig plate is a work supporting jig plate set on a fixed base of a transfer processing apparatus, a clamp mounting plate standing on the work supporting jig plate, and a clamp mounting plate. And clamp means for removably fixedly disposing the work on the work supporting jig plate or the clamp mounting plate.

Then, a supporting method including attachment / detachment of the work to / from the work supporting jig plate is performed as follows. That is, in the first step of processing using the transfer processing apparatus, the clamp means is operated to fix the work on the work supporting jig plate or the clamp mounting plate. That is, it is a work attaching step. Next, after the completion of the first work attaching step, the first step of machining is performed for the first time. Then, when all the processing steps for the work by the transfer and processing device are completed, the work is removed from the work supporting jig plate or the clamp mounting plate by releasing the clamp means.
That is, it is a work removing process.

[0004]

The conventional work supporting jig plate has the following problems. The first example of the clamping means is performed by a cam-driven rotary claw. That is, the rotating claw presses the work by the first operation of the cam to fix the work to the work supporting jig plate. The second movement of the cam releases the pressing of the rotary claw against the work, and the work can be removed from the work supporting jig plate. The second example of the clamping means is performed by an air cylinder. That is, by driving the air cylinder by the first operation and pressing the work,
The work can be removed from the work support jig plate by fixing the work to the work support jig plate, releasing the pressing of the work with the air cylinder in the non-driving state. According to the above, 1) it is necessary to attach the clamping means for attaching and detaching the work to the work supporting jig plate without fail. According to this, the work supporting jig plate is increased in size and weight, and in particular, the conveying means is increased in size in order to enhance the conveying ability of the conveying means for conveying the work supporting jig plate to the next step. Therefore, the work supporting device cannot be downsized due to the increase in the size of the work supporting jig plate and the carrying means. 2) In order to automatically perform the attachment / detachment of the work by the clamp means, a driving force such as electricity or air pressure is required, and the economic effect cannot be enhanced. 3) Providing the clamp means increases the manufacturing cost of the work supporting jig plate, and cannot provide an inexpensive transfer processing device. In particular, in such a transfer processing apparatus, since a large amount of work is continuously flowed, it is necessary to prepare a large number of work supporting jig plates, and the economical loss is extremely large.

Further, according to the conventional work supporting method, the mounting process using the clamp means is required for mounting the work on the work supporting jig plate in the first step of processing in the transfer / processing apparatus. In the final step of processing, an unloading step using a clamp means is required to bring the workpiece out of the workpiece supporting jig plate. According to this, mounting, non-mounting, and processes that are completely unrelated to processing are required, and it is not possible to reduce the tact time of workpiece processing, and it is not possible to reduce the product processing cost. Can not be raised.

The work supporting method and the work supporting jig plate in the carrying and processing apparatus according to the present invention have been made in view of the above problems, and the work supporting jig plate can be used to support the work without using any special clamping means. By providing a transfer processing device that can be miniaturized and can improve production efficiency by providing a low-priced transfer processing device, the processing tact time of a workpiece can be shortened and the product processing cost can be reduced.

Has returned to its original position in the lower position.

As described above, according to the present invention, in the first working process in the first station, the work W is surely performed by performing the thread cutting work on the screw hole 10 which originally needs to be processed by the tap T. Since the work piece W can be fixed to the pallet plate 1, it is not necessary to provide special clamping means on the pallet plate 1 for fixing the work W to the pallet plate 1. Further, the clamping work for fixing the work W to the pallet plate 1 and the thread cutting work for the screw hole 10 can be simultaneously performed in the same work process.

After the completion of the first working process in the first station of the transfer processing apparatus, the support shaft 1B of the pallet plate 1 to which the work W is fixed is attached by the transfer means provided in the transfer processing apparatus, and the pallet is attached. The plate 1 is moved and fixedly arranged on the fixed bed of the second station. Then, the second processing operation is performed on the work W fixed to the pallet plate 1. Then, thereafter, the pallet plate 1 equipped with the work W is sequentially conveyed and fixed on the fixed bed of each station,
Required processing is performed at each station.

Then, the final machining work is performed on the work W of the pallet plate 1 fixed on the fixed bed of the final station, and when the whole machining work on the work W is completed, the screw portion 4A of the tap T is It is in a state of being screwed into the screw hole 10. (This state is the tapped state in FIG. 4.) In such a state, the screw tightening driver 12 is moved upward again, and the square concave portion 12A of the screw tightening driver 12 is moved to the shank square portion 4 of the tap T.
It is fitted in B and the screw tightening driver 12 is turned over. According to the above, the tap T is pulled out from the threaded hole 10 without damaging the threaded female formed in the threaded hole 10 to form the threaded hole in the threaded hole 10 and the work W.
Is released from the seating surface 2A of the support portion S of the pallet plate 1 to free the work W. Therefore, it is possible to freely take out the work W that has been completely processed from the pallet plate 1. The state in which the tap T is pulled out from the work W is the same as in FIG.

In the second supporting portion 5, the two tap guide members 3 can be removed from the tap receiving hole 2B by removing the E-clip E from the tap receiving hole 2B, and the screw 8 can be further attached. By removing the guide tube portion 6

As described above, according to the present invention, 1) by performing the screw cutting work by rotating the tap forward toward the work arranged on the work supporting jig plate,
The work can be fixed to the work support jig plate and fastened. Then, in the state where all the processing steps in the transfer processing apparatus are completed, the tap is reversed and the tap is pulled out from the work, thereby releasing the fastening between the work and the work supporting jig plate. Therefore, since the normal rotation and the reverse rotation of the tap, which are originally necessary for the thread cutting work, are used to fasten and release the work from the work supporting jig, the special clamping means is used to perform the fastening process for the work as a single process. And the release step is no longer necessary. According to the above, the work is put into the transfer processing device,
Since the tact time until the work is completed and the work is taken out can be shortened, it is possible to reduce the work cost of the work and to provide a transfer / processing apparatus suitable for mass production. 2) According to the work supporting jig plate of the present invention, it is not necessary to provide the work supporting jig plate with a special clamping means. According to this, the work supporting jig plate can be made extremely lightweight without increasing the weight, and in particular, the conveying means provided in the conveying / processing device can be made small and lightweight, and further, the conveying means is driven. The driving energy such as electricity and fluid pressure can be reduced. Further, since the work supporting jig device is formed to have an extremely simple shape and a small size, it is possible to reduce the size of the transfer means and the size of the transfer processing device as a whole. In particular, the conveying and processing apparatus generally has a large number of processing stations and thus tends to be large in size, and its installation poses a problem. In the present invention, however, the degree of freedom of installation can be greatly improved. In addition, the absence of the clamp means does not require a drive unit for operating the clamp means such as an electromagnetic device, a motor, a hydraulic / pneumatic cylinder, etc. According to this, drive energy is not required, which is economical. The effect can be enhanced. In addition, since there is no clamping means, a work supporting jig device for one piece can be manufactured at a low cost, and in particular, a large number of work supporting jig devices are required in the transfer processing device. The total manufacturing cost of the work supporting jig device could be reduced significantly. Furthermore, the work is not pressed outside the screwing by the tap, which means that scratches and deformations of the work are completely eliminated, and the product's merchandise can be greatly improved. is there.

Further, since the guide cylinder portion protruding further upward from the seating surface is provided in the support portion and the escape hole provided in the work is fitted and arranged along the guide cylinder portion, the screw lower hole is formed. Since the axis of the tap and the axis can be more accurately arranged, the screw holes can be accurately machined, and the workpiece can be accurately arranged on the support part. Was improved.

Further, since the guide tube portion is detachably arranged with respect to the support portion, when changing the thread diameter of the tap screw portion, only the guide tube portion is changed without changing the entire pallet plate. Therefore, it is possible to cope with the change of the screw diameter very easily, the cost increase required for the change can be reduced as much as possible, and the work supporting jig plate having high versatility can be provided.
