Description

The present invention relates to a processing machine for processing machine parts, which comprises a parts feeding mechanism for feeding parts one after another at a processing position and a processing machine including the same.

Machining machines that manufacture and process various parts such as screws and bolts are equipped with a parts feeding mechanism that mounts parts one by one and feeds them to the next machining position at high speed, accurately, and frequently. There is something that is. In general, the parts feed mechanism includes a shaft that extends from a position inside the processing machine that houses many parts or another position outside to the processing position, and a shaft that mounts the parts and moves the parts along the shaft to the processing position. It is equipped with a bushing to be transferred and a drive unit for moving the bushing.
In some cases, the bushing is fixed and the parts mounted on the shaft are transferred, and the parts are transferred due to the relative relationship between the shaft and the bushing.

As a conventional component feeding mechanism, there is a shaft having a cylindrical or polygonal column and a bushing that transfers mounted components in the axial direction of the shaft while sliding on the outer peripheral surface of the shaft via bearings. However, those shafts and bushings slid and moved without rotation, and the bushings or parts mounted on the shafts were only transferred in the mounted state without rotational movement.

However, depending on the processing content of the processing machine, for example, it may be desired to transfer the machine from the mounted state to the next processing location in a half-turned state. Not limited to half rotation, depending on the next processing purpose at the transfer destination, it may be desired to deliver to the transfer destination in a state of being rotated by various angles. There was no parts feeding mechanism to meet such demands.

In Patent Document 1, a cylindrical shaft body (corresponding to a shaft) slides in a hollow portion of a deformed hexagonal housing (corresponding to a bushing), and the shaft body and the housing move in the shaft body direction via a bearing. It moves relative to each other and is a mechanism called a linear motion bearing. According to this mechanism, if the component is mounted on the housing, the component can be transferred in the axial direction.
However, in this mechanism, the shaft body is basically circular in cross section, and a plurality of concave grooves in the axial direction are formed on the surface of the shaft body to prevent the housing from rotating. It has the structure of. In this way, the shaft body and the housing do not rotate, but only move relatively in the axial direction. In this case, even if the parts are mounted on the housing, the parts cannot be delivered to the transfer destination in a rotated state.
In addition, since this bearing has a structure in which a ball is arranged between the shaft body and the housing to form a bearing mechanism between the shaft body and the housing, the bearing should be replaced if the ball of the bearing is damaged or worn. Is difficult and maintenance costs are high.

The processing machine shown in this figure shows a part of its structure. FIG. 2 is a perspective view showing another embodiment of the present invention, and in particular, shows a case where the bushing of the component feeding mechanism is fixed to the processing machine. FIG. 3 is a diagram showing an embodiment of the component feeding mechanism of the present invention, and in particular, is a diagram showing a case where there is one bushing. FIG. 4 is a diagram showing the appearance of the bushing of the component feeding mechanism shown in FIG. 3 in the longitudinal direction. FIG. 5 is a side view of the bushing shown in FIG. FIG. 6 is a sectional view taken along the line AA of the bushing shown in FIG. FIG. 7 is a diagram showing another embodiment of the component feeding mechanism of the present invention, and in particular, is a diagram showing a case where two bushings are connected.

FIG. 1 is a perspective view showing a suitable component feeding mechanism of the present invention and a part of the structure of a processing machine provided with the mechanism.
In FIG. 1, the processing machine includes various structures in addition to the illustrated parts feeding mechanism, depending on the purpose of processing and the object to be processed. In FIG. 1, basically, the component feeding mechanism 1 includes a bushing 2 and a shaft 3 penetrating the central portion of the bushing 2. The shaft 3 is fixed to the base 4 which is a part of the processing machine, and does not move or rotate.

The structure of the bushing 2 will be described in detail in FIGS. 3 to 6, and the bushing 2 has a regular hexagonal outer circumference and a circular hollow columnar shape on the inner circumference of the through hole.
The shaft 3 has a thickness sufficient to enter the through hole of the bushing 2 and slide, and has a regular hexagonal solid columnar cross section. A surface 10 including each side of a hexagonal cross section extends axially to the surface of the shaft 3. And the six surfaces 10 have a twist.
The bushing 2 reciprocates along the surface 10 of the shaft 3 via bearings 9a and 9b installed between the bushing 2 and the shaft 3.
Here, since the surface surface 10 of the surface of the shaft 3 has a twist, when the bushing 2 reciprocates in the axial direction of the shaft 3, the bushing 2 reciprocates while rotating.

The bushing 2 reciprocates in the axial direction of the shaft 3 by using the cylinder shaft 6 and the cylinder head 7 that expand and contract the gas cylinder 5 as a drive source 8. The gas cylinder 5 reciprocates the cylinder shaft 6 and the cylinder head 7 by the inflow and outflow of gas, but other fluids such as oil may be used in addition to the gas.
The reciprocating motion of the cylinder shaft 6 of the gas cylinder 5 and the cylinder head 7 as the drive source 8 is received at the end of the bushing 2.

A box 12 for receiving a component 11 supplied from the outside is fixed to the other end of the bushing 2. A magnet 13 exists in the box 12, and the metal component 11 received from the outside sticks to the magnet 13, and even if the bushing 2 rotates, the component 11 does not fall. If the part is other than metal, it is easy to have a structure that prevents the part from falling, instead of a magnet.
The received part 11 moves to the end of the shaft 3 while rotating with the bushing 2, and is not shown, but is passed to the next processing location for processing. At that time, the component 11 is rotated by a certain angle. In the next machining, if it is desired to deliver the part 11 to the machining place in a state of being half-turned, it may be half-turned or one-and-a-half turns while the part 11 is moving the shaft 3. By calculating the desired rotation angle, moving distance, length of the shaft 3, twist of the six surfaces 10, and the like in this way, the component 11 can be delivered in a state of being rotated by a desired angle.

In this way, in the component feeding mechanism 1 installed in the processing machine, when the bushing 2 through which the shaft 3 fixed to the processing machine penetrates moves in the axial direction on the surface of the shaft 3 by the drive source 8, the shaft 3 The bushing 2 moves while rotating on the surface of the shaft 3 due to the degree of twisting of the six surfaces of the surface of the bushing 2, and the part 10 received by the bushing 2 is rotated by a desired angle to the same processing machine or another processing machine. It can be passed to a certain next processing process.
Then, it is possible to freely set a state in which the component 11 is rotated by half, a state in which it is rotated by 90 degrees, a state in which it is rotated by 270 degrees, and the like, depending on the degree of twist.
Of course, depending on the setting, even if the part moves while rotating, if it finally returns to the original state, it is possible to pass it in the same state as if it did not rotate at the next processing location.

FIG. 2 is a perspective view showing another embodiment of a suitable parts feeding mechanism of the present invention and a part of the structure of a processing machine provided with the same.
In FIG. 2, the component feeding mechanism 14 has the same basic mechanism as the component feeding mechanism 1 of FIG. 1, and the bushing 16 and the shaft 19 penetrating the bushing 16 reciprocate relatively in the axial direction. Common. Further, the structures of the bushing 16 and the shaft 19 are the same as those of the component feeding mechanism 1 shown in FIG.
In the component feeding mechanism 1 of FIG. 1, the shaft 3 is fixed to the base 4 of the processing machine, and the bushing 2 reciprocates on the outer peripheral surface of the shaft 3 by the drive source 8 via the bearings 9a and 9b. On the other hand, in the component feeding mechanism 14 of FIG. 2, the bushing 16 is fixed to the base 15 of the processing machine, and the shaft 17 is slid by the drive source 19 in the through hole of the bushing 16 via the bearings 18a and 18b. It moves back and forth.
That is, relatively, the bushings 2 and 16 and the shafts 3 and 17 penetrating the bushings 2 and 16 reciprocate in the same manner, but the bushing 2 is fixed to the bases 4 and 15 of the processing machine or reciprocates. , 16 or shafts 3 and 17 are different.

In FIG. 2, the bushing 16 is fixed to the base 15 of the processing machine. The shaft 17 slides in the through hole of the bushing 16 via the bearings 18a and 18b to reciprocate. Further, as in the case of the component feeding mechanism 1 of FIG. 1, the shaft 17 has a solid columnar shape having a hexagonal cross section, and the six surfaces 19 have a twist. Therefore, when the shaft 17 is pushed axially by the drive source 20, the shaft 17 rotates in the through hole of the bushing 16 via the bearings 18a and 18b by the amount of twist while the bushing 16 is fixed. While sliding, it reciprocates.
The reciprocating cylinder shaft 22 of the gas cylinder 21, which is the drive source 20, is rotatably connected to the shaft 17 at one end of the shaft 17. That is, the cylinder shaft 22 of the cylinder 21 does not rotate and only reciprocates, but the shaft 17 pushed by the cylinder shaft 22 is connected so as to be able to rotate.
The other end of the shaft 17 has a structure in which the component 23 can be received from the outside, and the component 23 received by the rotating and reciprocating shaft 17 can be delivered to the next processing location in a rotated state. Further, it is natural that the parts feed mechanism 1 of FIG. 1 can be passed to the next processing place in the same state as when it did not rotate.

In this way, the parts feeding mechanisms 1 and 14 shown in FIGS. 1 and 2 allow the parts 11 and 23 to be delivered to the next processing location in a state of being rotated by a predetermined angle after being received.

FIG. 3 is a plan view showing in detail the bushing 2 and the shaft 3 of the component feeding mechanism 1 shown in FIG.
Further, FIG. 4 is a view obtained by slightly changing the angle of the bushing 2 shown in FIG.
Further, FIG. 5 is a side view of the bushing 2 shown in FIG.
Further, FIG. 6 is a sectional view taken along the line AA of the bushing 2 shown in FIG.

As can be seen from FIGS. 3, 4, 5, and 6, the bushing 2 is a hollow columnar shape having a regular hexagonal cross section on the outer circumference and a circular through hole on the inner circumference through which the shaft 3 can penetrate. Bearings 9a, 9b, 9c are embedded in three of the six outer peripheral surfaces at positions facing through holes in the bushing 2, and the bushings 2 and shaft 3 are slid by the bearings 9a, 9b, 9c. It has a structure that allows it to move and move. Since it is supported in three directions on three surfaces, the shaft 3 can maintain a stable position in the through hole of the bushing 2.

The bearings 9a, 9b, and 9c not only have a bearing function in which a ball is sandwiched between the bushing 2 and the shaft 3 and are provided by the bushing 2, the shaft 3, and the ball, but are also independent of the bushing 2 and the shaft 3. Since the bearing is embedded in the bushing 2, the bearings 9a, 9b, 9c can be replaced if they are worn or damaged. Moreover, since a commercially available bearing can be used, it can be easily replaced at low cost, which is convenient for the user of the parts feeding mechanism and the processing machine equipped with the mechanism for maintenance.

FIG. 7 shows an embodiment in which two bushings 25a and 25b are connected by bushing connecting members 24a and 24b.
In the embodiment shown in FIGS. 1 and 2, there is only one bushing 2 and 16, and each bushing 2 and 16 has one bearing 9a, 9b, 9c, 18a on three of the six surfaces. One 18b and one 18c are arranged. Therefore, when the bushings 2 and 16 slide on the surfaces 10 and 19 of the shafts 3 and 17, unstable movements such as the bushings 2 and 16 vibrating on the surfaces 10 and 19 of the shafts 3 and 17 occur. There is a possibility of doing. Therefore, as shown in FIG. 7, if the two bushings 25a and 25b are connected by the bushing connecting members 24a and 24b, the bushings 25a and 25b have less vibration and can slide stably.
