[Detailed description of the invention] Attachment of tacks, snaps, etc. is done by machine. The present invention relates to a machine for attaching rivets, snaps, etc., and specifically relates to a support for driving rivets and a machine. a base tool that works as a The installation of tacks, snaps, etc. that have a tack holder surrounding the rivet set is not recommended. Regarding machines. The tack holder is attached to a clamp that swings into the grasping position. .

Traditionally, this type of machine requires tool changes when using various studs and snap parts. is needed. This time-consuming process can be done by skilled workers using other tools. It is done. As a result, the entire machine is stopped for a meaningless period, resulting in an economical efficiency will be reduced.

The object of the invention is to provide a machine of this type with individual tools for fastening, snapping and snapping parts in a short time. The idea is to create a system that allows for replacement.

This problem can be solved by pulling out the clamp's hinge pin when removing the clamp. achieved.

In order to obtain these improvements, this type of machine, whether simple in structure or not, is It is designed to be characterized by economical efficiency. Also, what is the conventional structure? On the contrary, it is possible to replace the clamp in a short time. Shapes that have been manufactured so far Replace the clamp when handling snap parts. each to use The clamp must be adjusted to suit the shape of the new snap part being handled. No. This replacement work is simply pulling out the hinge pin of the clamp; is a simple task that can be performed by non-skilled workers. This clamp is easy to use. Following a simple removal operation, the end of the ram is now movable, e.g. for the upper stud set. can be removed if necessary. Clamp that matches the snap parts to be installed The plug is installed by plugging it in, which is just as quick as removing it. It's an easy task. Therefore, downtime of the equipment is kept to a minimum and high This will result in greater economic efficiency.

This removal and installation work is accomplished using the pull-out handle located at the end of the hinge pin. It is done. This means that installation as well as removal can be accomplished without the use of separate tools. It means that it can be applied.

For removal and installation work, remove it from the front of the crossbar that connects the two hinge pins. This can be done easily depending on the position of the handle. In this way, the hinge pin is can be engaged or removed by a pulling motion or a single insertion motion. I can do that.

To comply with safety standards, safety screws can be placed on the crossbar.

Therefore, it can be removed by loosening the safety screw only once with the removal handle. It becomes possible to disengage the loss bar and the hinge pin. What is this safety screw? For example, a fixing screw whose crossbar is released after a slight rotation of the screw.

From the technical characteristics of the support, the lower part for the bearing bracket of the clamp on the clamp support It is advantageous to provide an open insertion slot. Therefore, this plug-in On the opposite side of Misro 7F, the clamp support has a part pierced by a hinge pin. This forms a bridge-like support. When installing the clamp, It is necessary to guide the clamp into the insertion slot. Bearing opening and clamp support As soon as the openings are aligned, the hinge pin can be inserted.

A base tool with a downward bayonet connection is located within the support. It is advantageous. It can be removed from the fixed position by removing the hinge pin. It is fixed by a tiltable bearing pedestal that can be tilted. Similarly, the base tool The replacement is a hinge pinot, i.e. a tiltable that fixes the plug-in connection of the base sole Only the hinge pin of the bearing pedestal can be removed. After the hinge pin is removed, The bearing block can be removed from its fixed position at the same time as the base tool is released The base tool would then be similarly removed and replaced. Following this exchange Then, the bearing stand is fixed in position by inserting the hinge. This operation , which also takes place within a short time and reduces the downtime which reduces the economic efficiency of the machine concerned. let

To prevent the hinge pin of the bearing pedestal from being unintentionally removed from its insertion position, Secure the pedestal hinge pin in place. This can be used, for example, as a suspension law or This can be achieved by the hinge pin forming a circular groove in which the stop pin engages.

Once the stall condition is released, the hinge pin can be removed. This operation The operation can also be carried out without tools.

As shown in Figure 45. In the starting position, the bypass switch 26' is actuated by the cam surface 20'; The bypass switch 26° is thereby opened.

Another difference is that the rod 55 or carriage 56 is in the fully advanced position. The key is to operate at 65°. That is, it is in the closed position. This operation is carried out This is done through the blades 56' of the gino 56.

Another difference is that the rod 55 or carry lug 56 can be swiveled in the fully advanced position. switch 65' is activated. That is, it is in the closed position. This operation This is done via the vanes 56' of the ridge 56.

The foot only moves when the carriage 56 or rod 55 is in the fully forward position. Work can be started using the foot switch 82. The carijino moves sufficiently forward. When not, the bearing stand 46 is locked, but the switch 65° does not close. 1st In this embodiment, the finger protection switch is actuated, i.e. the bearing rest is locked. It had become. However, the ram operation is possible even if the snap parts are not inserted. It was possible to do so. Therefore, this modification is the best possible configuration. It provides structure.

Drive disk with cam surfaces 20', 21' as shown in Figures 46 and 47 18 has already been rotated by a certain angle. The stud holder 28 is connected to the bearing stand 46 and the holder 2. They have moved to a position where they can maintain a safe distance within 8 minutes. Furthermore, Figure 47 shows 65° is released and the carriage 56 is moving backward when it is open. It shows. Switch 80 is still closed and the electrical Motor 24 continues to drive.

However, if a foreign object or finger appears between the rivet holder and the bearing block, the relative relationship between the rivet holder and the ram As a result of the movement, switch 80 will be opened.

When the safe distance is secured, the drive continues, and as a result, as shown in Figure 48, The intermediate position can be obtained. From this Figure 48, it is confirmed that the bearing stand 46 has already fallen down. I can recognize it. This is made possible by the rod 55 releasing the bearing pedestal. Sui The switch 80 is still closed in this intermediate position. The ram moves further and this switch Before the switch 80 opens, the cam surface 20' closes the bypass switch 26'' and the drive The deafness continues all the time.

Subsequently, the ram reaches another dead center position as shown in FIGS. 49 and 50. this place In this case, FIG. 50 shows the state in which the bypass switch 26' is released and thereby closed. ing.

Furthermore, due to the rotation of the drive device, the rod 55 carried by the carriage 56 is engaged. It returns to the supporting position of the bearing stand 46 via the coupling lever 59. At the same time, this The opening carries the new snap lower part 54. In this case, the pushing ram 66 carries the upper part of the snap 38 towards the stud holder 28. upward movement of ram 6 ends when the cut-off switch 25'' is actuated by the cam surface 21'. .

The monitor switch 65 is activated only when the rod 55 has moved completely forward. This makes it possible to start a new riveting operation.
