Description

[Technical field]

[0001] The present invention relates to a crank-type press device and a terminal crimping device including the same. [Background technology]

[0002] Background Art There has been known a crank-type press device that includes a rotating crankshaft, a link mechanism connected to a portion of the crankshaft that is eccentric from the center of rotation, and a press member connected to the link mechanism, in which the press member moves linearly as the crankshaft rotates, thereby pressing an object.

[0003] For example, Patent Document 1 discloses a terminal crimping device including a crank-type press device and an applicator. The crank-type press device has an output shaft as a crankshaft, a link mechanism, and a slide body as a press member. The output shaft is rotatably supported by a bearing, and the bearing is provided at a portion closer to the base than the connection portion of the output shaft with the link mechanism. The tip of the output shaft is cantilevered by the bearing. The applicator has a crimper holder connected to the slide body, a crimper attached to the crimper holder, and an anvil. An eccentric pin is provided at a portion eccentric from the rotation axis of the output shaft. The link mechanism is connected to the eccentric pin. When the output shaft rotates, the eccentric pin revolves around the rotation axis and moves up and down. Accordingly, the slide body moves up and down. When the slide body moves downward, the crimper approaches the anvil. Then, the crimper presses the electric wire and the terminal supported on the anvil, thereby crimping the terminal to the electric wire.

[0004] Patent Document 2 discloses a crank-type press machine in which the tip of a rotating shaft is supported at both ends by a pair of bearings. In this crank-type press machine, a disk having an eccentric pin is connected to the tip of the output shaft of the reducer. The disk forms the tip of the rotating shaft. The upper end of a crank rod is connected to the eccentric pin, and a ram is attached to the lower end of the crank rod. The base side and tip side portions of the disk from the eccentric pin are each rotatably supported by the bearings. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2007-280792 A [Patent Document 2] Japanese Patent Application Publication No. 8-236251 Summary of the Invention [Problem to be solved by the invention]

[0006] In the terminal crimping device disclosed in Patent Document 1, when the crimper presses the electric wire and the terminal downward, an upward reaction force is generated in the crimper. This reaction force acts as an upward force on the tip of the output shaft via the crimper holder, the slide body, and the link mechanism. That is, during pressing, a force perpendicular to the rotation axis is applied to the tip of the output shaft. In the crank-type press device disclosed in Patent Document 1, the tip of the output shaft is cantilevered by a bearing. Therefore, when an upward force is applied to the tip of the output shaft during pressing, a bending moment is generated in the output shaft. If the output shaft is not firmly supported by the bearing, there is a risk that the output shaft will swing out from the rotation axis. However, in order to firmly support the output shaft, it is necessary to arrange an auxiliary bearing at the other end of the crankshaft and then lengthen the crankshaft itself so that the distance between the bearing and the auxiliary bearing is sufficiently secured, which leads to an increase in the size of the crank-type press device.

[0007] On the other hand, in the crank-type press device disclosed in Patent Document 2, both the base side and tip side of the disk from the eccentric pin are supported by bearings. When pressing, an upward force is applied to the eccentric pin, and a bending moment is generated in the disk, but both the base side and tip side of the disk from the eccentric pin are supported by bearings near the eccentric pin. Therefore, it is possible to prevent the disk from swinging from the axis of rotation. However, in the crank-type press device disclosed in Patent Document 2, a pair of bearings must be disposed near the eccentric pin of the disk. Therefore, the crank-type press device disclosed in Patent Document 2 also leads to an increase in size of the device.

[0008] The present invention has been made in consideration of the above points, and its object is to provide a crank-type press device that can support a rotating body well and can be made compact, and a terminal crimping device equipped with the same. [Means for solving the problem]

[0009] The crank-type press apparatus according to the present invention includes a drive source that generates a rotational force, a rotating body, a bearing, a link mechanism, and a press member. The rotating body rotates around a first rotation axis by receiving the rotational force of the drive source. The rotating body has an eccentric part that is eccentric from the first rotation axis. The bearing rotatably supports the rotating body. The link mechanism includes a first connecting part that is rotatably connected to the eccentric part of the rotating body around a second rotation axis that is parallel to the first rotation axis, a link arm that extends from the first connecting part in a direction perpendicular to the second rotation axis, and a second connecting part provided on the link arm. The press member is rotatably connected to the second connecting part of the link mechanism around a third rotation axis that is parallel to the first rotation axis and the second rotation axis. The press member extends in the direction of a press axis that is perpendicular to the first rotation axis. The bearing and the eccentric part are arranged on the same straight line perpendicular to the first rotation axis.

[0010] According to the crank-type press device, when the driving source rotates the rotating body, the press member connected to the rotating body via the link mechanism moves in the direction of the press axis. As a result, the press member presses the object. When the press member presses the object, a reaction force acts on the press member. This reaction force is transmitted to the rotating body via the link mechanism, and a force in a direction perpendicular to the first rotation axis acts on the eccentric part of the rotating body. However, according to the crank-type press device, the bearing that rotatably supports the rotating body and the eccentric part to which the force acts are arranged on the same line perpendicular to the first rotation axis. Since the bearing and the eccentric part are not shifted in the direction of the first rotation axis, no bending moment due to the reaction force is generated in the rotating body. Therefore, the rotating body is less likely to swing from the first rotation axis, and the rotating body can be well supported by the bearing. In addition, there is no need to arrange a pair of bearings at the tip of the rotating body, which makes it possible to reduce the number of parts and make the device more compact.

[0011] The bearing and the eccentric portion may be disposed on a straight line parallel to the press axis, but are preferably disposed on the press axis, which allows the bearing to more stably support the rotating body during pressing.

[0012] The first connecting portion may be a first pin extending in the direction of the second rotation axis. The eccentric portion of the rotor may be an eccentric hole into which the first pin is rotatably inserted. The bearing and the first pin may be disposed on the same straight line perpendicular to the first rotation axis.

[0013] The second connecting portion may be a second pin extending in a direction of the third rotation axis. The press member may have a pin hole into which the second pin is rotatably inserted. The bearing and the second pin may be arranged on the same straight line perpendicular to the first rotation axis.

[0014] The drive source may be a motor. The rotating body may have an output shaft connected to the motor and a disk-shaped wheel connected to a tip of the output shaft. The bearing may be disposed around the wheel. The first connecting portion of the link mechanism may be connected to the wheel. The link arm of the link mechanism may be disposed on the side of the press axis opposite to the motor side.

[0015] According to the crank-type press device, it is not necessary to provide a pair of bearings aligned in the direction of the first rotation axis at the tip of the rotor, and the tip of the rotor can be made compact. According to the above, the link arm is arranged by utilizing the free space on the tip side of the compact rotor. Therefore, the link mechanism can be arranged compactly, and the device can be made even more compact.

[0016] A terminal crimping device according to the present invention includes the crank-type press device and an applicator having a crimper holder attached to the press member, a crimper fixed to the crimper holder, and an anvil disposed to face the crimper along the press axis or a straight line parallel to the press axis.

[0017] According to the above-mentioned terminal crimping device, the rotating body of the crank-type press device is stably supported and the crank-type press device can be made smaller, so that the terminals can be crimped well and the device can be made smaller. Effect of the Invention

[0018] According to the present invention, it is possible to provide a crank-type press device that can adequately support a rotating body and can be made compact, and a terminal crimping device including the same. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view of a crank-type press device (hereinafter simply referred to as a press device) 1 according to this embodiment. Fig. 2 is a front view of the press device 1. Fig. 3 is a side view of a terminal crimping device 2 according to this embodiment, showing a state in which an applicator 50 is attached to the press device 1. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2.

[0021] 1, the press device 1 includes a motor 10, a reducer 12, a wheel 14, a bearing 16, a link mechanism 20, and a press member 18. The press device 1 also includes a frame 30 that supports these components.

[0022] The frame 30 has a bottom plate 31, and a left side plate 32 and a right side plate 33 extending upward from the bottom plate 31. A central plate 34 is disposed between an upper portion of the left side plate 32 and an upper portion of the right side plate 33. The central plate 34 is fixed to the left side plate 32 and the right side plate 33.

[0023] The motor 10 is an example of a drive source that generates a rotational force. In this embodiment, the motor 10 is a servo motor. As shown in FIG. 4, the motor 10 has a rotating shaft 11 that extends in the direction of a first rotation axis C1, and this rotating shaft 11 is connected to a reducer 12. The reducer 12 has an output shaft 13. The rotation of the motor 10 is reduced in the reducer 12 and output from the output shaft 13.

[0024] A disk-shaped wheel 14 is fixed to the output shaft 13. The wheel 14 rotates together with the output shaft 13 around a first rotation axis C1. The first rotation axis C1 is a horizontal line. In this embodiment, the rotating shaft 11 of the motor 10, the output shaft 13 of the reducer 12, and the wheel 14 constitute a rotating body 15 that rotates by receiving the rotational force of the motor 10. In this embodiment, the rotating body 15 is constituted by combining a plurality of members, and the rotation speed of a part of the rotating body 15 (for example, the rotating shaft 11 of the motor 10) and another part (for example, the output shaft 13 of the reducer 12) is not the same, but is not particularly limited. Each part of the rotating body 15 may rotate at the same rotation speed, and the rotating body 15 may be an integral body. The rotating body 15 is configured to rotate around the first rotation axis C1 and extends in the direction of the first rotation axis C1. An eccentric hole 14a is formed at a position eccentric to the first rotation axis C1 of the wheel 14. The eccentric hole 14a is an example of an eccentric portion that is eccentric from the first rotation axis C1. The eccentric hole 14a extends in the direction of the second rotation axis C2 that is parallel to the first rotation axis C1.

[0025] The bearing 16 rotatably supports the wheel 14. A hole into which the wheel 14 is inserted is formed in the center plate 34, and the bearing 16 is fitted into this hole. The bearing 16 is disposed around the wheel 14 and is interposed between the center plate 34 and the wheel 14. The type of the bearing 16 is not particularly limited, and for example, a needle bearing, a ball bearing, a sliding bearing, or the like can be used. Furthermore, the hole itself may be used as a sliding bearing by forming it slightly larger than the wheel 14 and lubricating it with grease or the like as necessary.

[0026] The link mechanism 20 has a link arm 25, and a first pin 21 and a second pin 22 fixed to the link arm 25. The first pin 21 is rotatably connected to the eccentric hole 14a of the wheel 14. The first pin 21 and the second pin 22 are examples of a first connecting portion and a second connecting portion, respectively. Here, a bearing 17 is fitted into the eccentric hole 14a of the wheel 14, and the first pin 21 is rotatably supported by the bearing 17. As with the bearing 16, the type of the bearing 17 is not particularly limited, and for example, a needle bearing, a ball bearing, a sliding bearing, or the like can be used. In addition, the eccentric hole 14a itself may be used as a sliding bearing, and the first pin 21 may be directly supported by the eccentric hole 14a. The first pin 21 extends in the direction of the second rotation axis C2. The link arm 25 extends from the first pin 21 in a direction perpendicular to the second rotation axis C2. The second pin 22 extends in the direction of a third rotation axis C3 parallel to the first rotation axis C1 and the second rotation axis C2. In this embodiment, the first pin 21 and the second pin 22 are separate members from the link arm 25 and are assembled together. However, one or both of the first pin 21 and the second pin 22 may be integral with the link arm 25.

[0027] The press member 18 has a first part 18A to which the second pin 22 is rotatably connected, and a second part 18B fixed to the first part 18A. A hole 18a is formed in the first part 18A, and the second pin 22 is rotatably connected to the hole 18a. Here, a bearing 19 is fitted into the hole 18a of the first part 18A, and the second pin 22 is rotatably supported by the bearing 19. As with the bearing 16, the type of the bearing 19 is not particularly limited, and for example, a needle bearing, a ball bearing, a sliding bearing, etc. can be used. In addition, the hole 18a itself may be used as a sliding bearing, and the second pin 22 may be directly supported by the hole 18a. In this embodiment, the press member 18 is configured by assembling multiple parts (the first part 18A and the second part 18B, etc.), but is not particularly limited and may be configured by a single part. The press member 18 extends in the direction of a press axis V perpendicular to the first rotation axis C1. The press axis V is a vertical line.

[0028] 2, guide members 28 are provided on both the left and right sides of the press member 18. The guide members 28 guide the vertical movement of the press member 18. The press member 18 is slidably engaged with the guide members 28.

[0029] The press member 18 is connected to the wheel 14 via a link mechanism 20, so that the press member 18 moves up and down as the wheel 14 rotates. Fig. 2 shows the press member 18 in its uppermost position. Fig. 5 shows the press member 18 in its lowermost position. That is, Figs. 2 and 5 show the press member 18 at its top dead center and bottom dead center, respectively. The press member 18 can move up and down between the top dead center and bottom dead center.

[0030] As shown in Fig. 3, an applicator 50 is attached to the press device 1. The applicator 50 is a device that receives the driving force of the press device 1 to crimp a terminal 62 onto an electric wire 61. The press device 1 and the applicator 50 constitute a terminal crimping device 2. The applicator 50 has a crimper holder 51 connected to the press member 18, a crimper 52 fixed to the crimper holder 51, and an anvil 53. The crimper holder 51 moves up and down together with the press member 18.

[0031] The above is the configuration of the press device 1 and the terminal crimping device 2. Next, the operations of the press device 1 and the terminal crimping device 2 will be described.

[0032] When the motor 10 is driven with the press member 18 at the top dead center, the rotational force of the motor 10 is transmitted to the wheel 14 through the reducer 12, causing the wheel 14 to rotate. When the wheel 14 rotates, the first pin 21 of the link mechanism 20 moves downward, and the press member 18 connected to the link mechanism 20 moves downward. When the press member 18 moves downward, the crimper holder 51 connected to the press member 18 moves downward, and the crimper 52 fixed to the crimper holder 51 also moves downward. As a result, the crimper 52 approaches the anvil 53, and the electric wire 61 and the terminal 62 are sandwiched between the crimper 52 and the anvil 53 and crimped.

[0033] When the electric wire 61 and the terminal 62 are crimped, the crimper 52 receives an upward reaction force. This reaction force is transmitted to the press member 18 via the crimper holder 51, and is further transmitted to the wheel 14 via the link mechanism 20. Therefore, an upward force along the press axis V acts on the wheel 14.

[0034] As described above, the rotating body 15 is constituted by the rotating shaft 11 of the motor 10, the output shaft 13 of the reducer 12, and the wheel 14. The wheel 14 constitutes the tip of the rotating body 15. For example, as shown in FIG. 6(a), when the bearing 16 supporting the rotating body 15 is disposed on the base side of the press axis V, when an upward force F along the press axis V acts on the rotating body 15, a bending moment M1 is generated at the tip of the rotating body 15. This may cause the rotating body 15 to swing from the first rotation axis C1, and the rotating body 15 may not be supported well by the bearing 16. It is possible to stabilize the rotation of the rotating body 15 by adding an auxiliary bearing 16A, but in that case, it is necessary to lengthen the rotating body 15 so that the distance between the bearing 16 and the auxiliary bearing 16A is sufficiently secured, which may lead to an increase in size of the press device 1.

[0035] As shown in FIG. 6(b), it is possible to arrange bearings 16 on both the base side and the tip side of the press axis V of the rotor 15. In this case, a bending moment M2 is generated at the tip of the rotor 15, but since both bearings 16 firmly support the rotor 15, the rotation of the rotor 15 can be stabilized. However, in this case, in addition to the bearing 16 on the base side, a bearing 16 is also required on the tip side. This increases the size of the press device 1 and the number of parts.

[0036] On the other hand, as shown in Fig. 6(c), when the bearing 16 supporting the tip of the rotating body 15 is disposed on the press axis V, even if an upward force F along the press axis V acts on the rotating body 15, no bending moment is generated in the rotating body 15. Therefore, the rotating body 15 can be stably supported without increasing the size of the press device 1.

[0037] According to this embodiment, as shown in FIG. 4, the rotating body 15 is connected to the link mechanism 20 via the eccentric hole 14a of the wheel 14. During terminal crimping, the rotating body 15 receives an upward force along the press axis V from the eccentric hole 14a of the wheel 14. However, according to this embodiment, the bearing 16 supporting the wheel 14 and the eccentric hole 14a are both arranged on the press axis V. That is, the part of the rotating body 15 that receives a force in a direction perpendicular to the first rotation axis C1 (the part of the eccentric hole 14a) and the bearing 16 supporting the rotating body 15 are arranged on the same straight line (= the press axis V). Since the bearing 16 and the eccentric hole 14a are not misaligned in the direction of the first rotation axis C1, no bending moment is generated in the rotating body 15 even if the above force acts on the rotating body 15. Therefore, even if bearings are not arranged on both sides of the press axis V, the rotating body 15 is unlikely to swing from the first rotation axis C1. According to this embodiment, the rotating body 15 can be stably supported, and the press device 1 can be made compact.

[0038] Furthermore, according to this embodiment, since there is no need to provide a pair of bearings (see FIG. 6(b)) aligned in the direction of the first rotation axis C1 at the tip of the rotating body 15, the tip of the rotating body 15 can be made compact. Extra space can be provided on the tip side (left side in FIG. 4) of the rotating body 15. In this embodiment, the link arm 25 of the link mechanism 20 is disposed on the opposite side (left side in FIG. 4) to the motor side (right side in FIG. 4) of the press axis V. In other words, the link arm 25 is disposed in the extra space. Therefore, the link mechanism 20 can be disposed compactly, and the press apparatus 1 can be further reduced in size.

[0039] According to the terminal crimping device 2 of this embodiment, the rotating body 15 of the press device 1 is stably supported during terminal crimping, so that the terminal 62 can be satisfactorily crimped to the electric wire 61. In addition, since the press device 1 can be made compact, the terminal crimping device 2 can also be made compact.

[0040] Although one embodiment of the present invention has been described above, the embodiment is merely an example, and the present invention can be embodied in various other forms.

[0041] In the embodiment, the bearing 16 and the eccentric hole 14a are arranged on the press axis V, but the bearing 16 and the eccentric hole 14a only need to be arranged on the same straight line perpendicular to the first rotation axis C1, and are not necessarily required to be arranged on the press axis V. The bearing 16 and the eccentric hole 14a may also be arranged on another straight line parallel to the press axis V.

[0042] In the above embodiment, the first pin 21 and the second pin 22 are non-rotatably connected to the link arm 25, but one or both of the first pin 21 and the second pin 22 may be rotatably connected to the link arm 25.

[0043] The crank type press device according to the present invention may be incorporated into devices other than a terminal crimping device, and can be applied to any device that requires a pressing operation. [Explanation of symbols]
