Abstract

PURPOSE:To enable a plurality of different parts to be assembled by providing a pick-and-place unit adaptable to a plurality of parts of different types and two types of screwing machines. CONSTITUTION:An assembling apparatus is constituted from a part transferring unit 4 adaptable to a plurality of parts of different types and two types of screwing machines 2, 3 so that it is provided with two types of screwing changing-over functions and carry out up to the screwing in the same station with parts being deformed and held. An example of part transferring unit 4 adaptable to a plurality of different parts can transfer the parts with a same chuck for clamping a common portion of the parts and sliding the parts perpendicularly to the transferring direction, and properly moves forward and backward for change-over two screwing machines 2, 3 slidable on an assembling position. Thus, for example, four combinatiolns of two different types of parts and fastening screws can be assembled in the same station.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate part deformation assembly device, and more particularly, to a plate part modification and assembly device that can assemble many types of combinations depending on the assembly model in the same steel joint, and can also perform screw tightening. This invention relates to a parts deformation and assembly device.

Conventional devices of this type require dedicated conveyance devices for each of two different types of parts, for example, and the screw tightening also requires switching for each of these two different parts. The conventional method was to place two types of screw-driving machines in the back-end process of each of the two types of conveying equipment, and use either screw-driving machine after one of the parts was conveyed. It is necessary to add a deformation holding mechanism for the parts, and since the stations are separated into four stations, the occupied area becomes large and the cost becomes high.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to provide an apparatus for transforming and assembling plate parts that can assemble many types of parts, occupies a small area, and is inexpensive. The present invention
In order to achieve the above objectives, we have one component transfer device that can be adapted to multiple different types of components and two types of screw tightening machines, and are equipped with a function to switch between the two types of screw tightening. To provide an assembling device that allows screw tightening to be performed with the same stiffener in a deformed and held state. As an example of a component transport device that can be applied to multiple parts of different types as described above, by providing a common part to the multiple parts, it is possible to transport them with the same chuck that slides at right angles to the transport direction. By moving two screw tightening machines that can slide back and forth as appropriate and switching between them, you can, for example, tighten two different types of parts and tighten four screws.
It is possible to obtain a product with a function that allows different combinations to be assembled using the same steel joint.

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows the configuration of the apparatus of this embodiment. In the figure, a screw tightening machine A2 and a screw can each be slid onto the assembly position on the conveyor 1.

A tightening machine B3 is installed, and a component conveying device 4 is installed in a direction perpendicular to the conveyor 1. Both the screw tightening machine A2 and the screw tightening machine B3 are installed on a base 7 to which a linear guide 6 with a built-in bearing running on a track base 5 is attached, and positioning pins 8 and 81 are respectively provided on the base 7. By inserting it into the positioning hole 9, it is possible to fix the left and right positions when in use or not, and to select and use either one. Here, two types of screws AIO and Bll are shown in FIG.

Now, in FIG. 1, the parts conveying device 4 includes parts feeders A12. Part A14 sent from B13,
A chuck upper presser 16 and a chuck upper presser 17 which take the receiver B15 and hold it to the assembly position. Chuck base with chuck 18. Front and rear slide base 20 connected by chuck base 18 and fulcrum shaft 19. and parts feeder AI2. It is composed of a left and right slide base 21 that slides left and right on B13 for switching parts. The front and rear slide base 20 is normally used as a parts feeder AI for the more frequently used part A14.
2, and picks up the part A14 by operating the chuck air cylinder 22. Figure 3 shows the side surface of the chuck section in detail.
．． Chuck upper presser foot 17. In addition to the chuck air cylinder 22, the front and rear rollers 23 integrated with the chuck lower presser 16. return.

It is composed of a spring 24. When the chuck air cylinder 22 is operated, the chuck upper presser 17 directly connected to it is lowered, and the chuck upper presser 16 is also moved forward along the inclined part via the front and rear rollers 23, and finally the chuck upper presser 16 is moved forward. After reaching the forward end of the chuck upper presser 1
7 completes its descent, the part A14 is chucked between both chucks, and the chuck is released by returning to the origin by releasing the chuck air cylinder 22 and using the return spring 24.

4 and 5 show part A14 and part B15. This shows the assembled state of each. In Figure 4,
Since the part A14 needs to be brought into contact with the pin A26 provided on the part to be assembled 25, by swinging and inserting the part A14, and then releasing the swing and holding it, the elasticity of the contact piece 27 will cause the part A14 to contact the pin 26. It's in close contact. Part B15. FIG. 5, which shows the assembled state, is also similar to this. Part A141
By chucking the common chucked lip 28 with part B15 as described above, two parts can be chucked with the same chuck.
This makes it possible to transport various types of parts.

The above-mentioned swinging operation is performed around the fulcrum shaft 19 by rotational sliding between the fulcrum shaft 19 press-fitted into the chuck base 18 shown in FIG. 3 and the bearing 29 press-fitted into the front and rear slide bases 20. By the action of the tensile force of the swinging air cylinder 31 supported by the cylinder fulcrum 30 shown in FIG. Release the movement and return to the assembly home position.

To assemble the part B15, by operating the switching air cylinder 34, the left and right slide bases 21 slide until the front and rear slide bases 20 are positioned on the parts feeder B13, and the chuck part is moved from the parts feeder B13 to the part B15. The receiver is removed, and the switching air cylinder 34 returns to return the slide base 20 to the original parts feeder A.
The process returns to I2, and thereafter the i-adding order is the same as in the case of part A14 described above.

As explained above, according to the present invention, it is possible to transport many types of parts from different positions to the same position using one parts transport device, and to easily switch between two types of screws for the same assembly position. Therefore, it is possible to assemble a large number of combinations according to the assembly model at one station, and it is possible to realize a plate part deformation and assembly apparatus that occupies a small area and is inexpensive.
