Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and more specifically to a swing arm device. Background Technology

[0002] Existing clamping devices for wire harness processing can only transport and clamp one wire harness at a time. The left and right movement of the wire harness is achieved through guide rods or linear rail structures to align it with the processing station for the corresponding process. This technical solution occupies a large space, making it impossible to quickly switch the wire harness to different stations for different processes. Furthermore, it cannot enable multiple wire harnesses to be quickly switched at a single station to perform the same process, which affects processing efficiency and occupies a large space. Summary of the Invention

[0003] The present invention aims to provide a swing arm device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a swing arm device, comprising a base, a first drive mechanism, a second drive mechanism, a rotating disk, and a swing arm mechanism;

[0005] The rotating disk is rotatably mounted on the base. A clearance through hole is provided in the middle of the rotating disk. The first drive mechanism is driven and connected to the rotating disk. Multiple wire clamps for clamping wire harnesses are arranged side by side along the first direction on the swing arm mechanism. A guide rail, a slider and a connector are provided on the bottom side of the swing arm mechanism. The slider is slidably mounted on the guide rail along the second direction. The connector is fixedly connected to the top side of the rotating disk. The output axis of the second drive mechanism passes through the clearance through hole and is connected to the slider.

[0006] When the first drive mechanism is started independently, it drives the turntable to rotate, which in turn drives the swing arm mechanism to rotate, thereby allowing the wire harness to switch to different workstations for processing.

[0007] When the first drive mechanism and the second drive mechanism are started simultaneously, the first drive mechanism and the second drive mechanism cooperate to drive the swing arm mechanism to move back and forth along the first direction, so that the wire harnesses on the swing arm mechanism can be switched one by one for processing.

[0008] Preferably, the length direction of the swing arm mechanism is the front-to-back direction, and the width direction is the left-to-right direction. In this case, the first direction is parallel to the left-to-right direction, and the second direction is parallel to the front-to-back direction.

[0009] Preferably, the first drive mechanism includes a first motor that is vertically mounted on the base, a synchronous pulley that is fixedly mounted on the output shaft of the first motor, and a synchronous belt that connects the synchronous pulley to the rotating disk.

[0010] Preferably, the circumferential side of the rotating disk is provided with a toothed friction structure that mates with the timing belt.

[0011] Preferably, it also includes a transverse rocker arm. The second drive mechanism includes a second motor that is vertically mounted on the base. The output shaft of the second motor passes through a clearance through hole. One end of the transverse rocker arm is fixedly connected to the top end of the output shaft of the second motor. A cylinder is fixedly mounted on the top side of the other end of the transverse rocker arm. A cylindrical groove is opened at the bottom of the slider. The cylinder is rotatably disposed in the cylindrical groove to realize the movable connection between the slider and the transverse rocker arm.

[0012] Preferably, the swing arm mechanism includes a swing arm body, a sliding block, a support plate, and a front and rear drive assembly. The guide rail and connector are installed on the bottom side of the support plate, the front and rear drive assembly is installed on the top side of the support plate, the swing arm body is installed on the front and rear drive assembly via the sliding block, and multiple wire clamps are arranged side by side on the swing arm body. The front and rear drive assembly is used to drive the swing arm body to move back and forth in the front and rear direction to realize the synchronous adjustment of the front and rear positions of all wire harnesses.

[0013] Preferably, the front and rear drive assembly includes a third motor and a lead screw connected by a drive. The third motor drives the lead screw to rotate, thereby causing the sliding block to move back and forth on the lead screw in the front and rear direction, and in turn causing the swing arm body to move back and forth in the front and rear direction to realize the synchronous adjustment of the front and rear positions of all wire harnesses.

[0014] Preferably, the swing arm body includes a fixed plate, and multiple mounting positions are arranged side by side on the top side of the fixed plate. Each mounting position is provided with a cylinder, an assembly rod and a guide seat that cooperate with each other. The bottom of the assembly rod is provided with a slide rail, which slides and cooperates with the guide seat. The cylinder is driven to connect with the assembly rod. The wire clamps are installed on the assembly rod one by one. The cylinder drives the assembly rod to move back and forth in the front and rear direction to realize the individual front and rear position adjustment of the corresponding wire harness.

[0015] Preferably, each mounting position is provided with multiple guide seats, and the multiple guide seats are arranged in the front-to-back direction.

[0016] Preferably, the swing arm body further includes a longitudinal swing rod, a fixed seat is provided above the rear end of the assembly rod, the rear end of the longitudinal swing rod is rotatably mounted on the fixed seat, a wire clamp is installed above the front end of the longitudinal swing rod, and a spring is installed between the front end of the assembly rod and the middle of the longitudinal swing rod.

[0017] Preferably, the swing arm body also includes an inverted U-shaped protective cover, with the bottom sides of the protective cover fixedly installed on the left and right sides of the fixed plate, respectively.

[0018] The present invention has the following beneficial effects:

[0019] This invention utilizes a single activation of the first drive mechanism to rotate the turntable, which in turn drives the swing arm mechanism, allowing the wire harness to switch to different workstations for processing. Simultaneous activation of the first and second drive mechanisms causes the swing arm mechanism to move back and forth in the left-right direction, enabling the wire harnesses on the swing arm mechanism to be processed one by one. In other words, through the cooperation of the first and second drive mechanisms, the turntable, and the swing arm mechanism, on the one hand, wire harnesses can be quickly switched to different workstations for different processes; on the other hand, multiple wire harnesses can be quickly switched at a single workstation to perform the same process, thereby improving processing efficiency. Furthermore, the overall structural layout is more rational and compact, occupying less space. Attached Figure Description

[0030] For ease of explanation below, clockwise and counterclockwise directions in this embodiment are both based on... Figure 3 The top-down view in the image is used as a reference.

[0031] See Figure 1-6 As shown, as an embodiment of the present invention, a swing arm device is provided, including a base 3, a first drive mechanism 5, a second drive mechanism 6, a rotating disk 4 and a swing arm mechanism. The length direction of the swing arm mechanism is the front-to-back direction, and the width direction is the left-to-right direction.

[0032] The rotating disk 4 is rotatably mounted on the base 3. A clearance through hole is provided in the middle of the rotating disk 4. The first drive mechanism 5 is driven and connected to the rotating disk 4. Multiple wire clamps 1 for clamping wire harness 2 are arranged side by side along the left and right direction on the swing arm mechanism. A guide rail 20, a slider 21 and a connector 22 are provided on the bottom side of the swing arm mechanism. The length direction of the guide rail 20 is parallel to the front and back direction. The slider 21 is slidably mounted on the guide rail 20 along the front and back direction. The connector 22 is located in front of the guide rail 20 and is fixedly connected to the top side of the rotating disk 4. The slider 21 is slidably mounted on the guide rail 20. The output axis of the second drive mechanism 6 passes through the clearance through hole and is connected to the slider 21.

[0033] When the first drive mechanism 5 is started alone, the first drive mechanism 5 drives the turntable 4 to rotate, which in turn drives the swing arm mechanism to rotate, thereby allowing the wire harness 2 to switch to different workstations for processing.

[0034] When the first drive mechanism 5 and the second drive mechanism 6 are started simultaneously, the first drive mechanism 5 and the second drive mechanism 6 cooperate to drive the swing arm mechanism to move back and forth in the left and right directions, so that the wire harness 2 on the swing arm mechanism can be switched one by one for processing.

[0035] Specifically, there are four wire harnesses 2 and four wire clips 1 that correspond to each other. Of course, there can also be other numbers, such as six.

[0036] Specifically, the first drive mechanism 5 includes a first motor 51 that is vertically mounted on the base 3. A synchronous pulley 52 is fixedly mounted on the output shaft of the first motor 51. A synchronous belt 53 connects the synchronous pulley 52 and the rotating disk 4. The layout is more reasonable and compact, and the transmission is more stable.

[0037] Specifically, it also includes a horizontal rocker arm 62, and the second drive mechanism 6 includes a second motor 61 that is vertically mounted on the base 3. The output shaft of the second motor 61 passes through a clearance through hole. One end of the horizontal rocker arm 62 is fixedly connected to the top end of the output shaft of the second motor 61. A cylinder 63 is fixedly mounted on the top side of the other end of the horizontal rocker arm 62. A cylindrical groove 211 is opened at the bottom of the slider 21. The cylinder 63 is rotatably disposed in the cylindrical groove 211 to realize the movable connection between the slider 21 and the horizontal rocker arm 62.

[0038] The swing arm device of the present invention is mainly used for the terminal crimping and waterproof plug sleeve processing of wire harness 2. The terminal crimping mechanism and the waterproof plug sleeve mechanism and their corresponding processing stations are located on the periphery of the swing arm device.

[0039] When it is necessary to switch the wire harness 2 to different workstations for processing, the first drive mechanism 5 is activated separately, which in turn drives the rotating disk 4 to rotate, thereby driving the swing arm mechanism to rotate, so that the wire harness 2 can be switched to different workstations for processing. Specifically, when the first drive mechanism 5 rotates in the clockwise direction, the rotating disk 4 and the swing arm mechanism also rotate in the clockwise direction. Conversely, when the first drive mechanism 5 rotates in the counterclockwise direction, the rotating disk 4 and the swing arm mechanism also rotate in the counterclockwise direction.

[0040] When it is necessary to move the wire harness 2 on the swing arm mechanism left and right to switch it for processing one by one, the first drive mechanism 5 and the second drive mechanism 6 are activated simultaneously. The first drive mechanism 5 and the second drive mechanism 6 cooperate to drive the swing arm mechanism to move back and forth in the left and right direction, so that the wire harness 2 on the swing arm mechanism can be switched for processing one by one. Specifically, when the first drive mechanism 5 rotates in the clockwise direction and the second drive mechanism 6 rotates in the counterclockwise direction, the swing arm mechanism moves to the right. Conversely, when the first drive mechanism 5 rotates in the counterclockwise direction and the second drive mechanism 6 rotates in the clockwise direction, the swing arm mechanism moves to the left.

[0041] The above technical solution, with the cooperation between the first drive mechanism 5, the second drive mechanism 6, the rotating disk 4 and the swing arm mechanism, enables the wire harness 2 to quickly switch to different workstations for different processes, and enables multiple wire harnesses 2 to quickly switch at a single workstation to achieve the same process, thereby improving processing efficiency. The overall structure layout is more reasonable and compact, and occupies less space.

[0042] In this embodiment, the circumferential side of the rotating disk 4 is provided with a toothed friction structure 41 that cooperates with the timing belt 53, thereby increasing the friction between the timing belt 53 and the rotating disk 4, further improving the rotational stability of the rotating disk 4, and thus ensuring processing accuracy and stability.

[0043] In this embodiment, the swing arm mechanism includes a swing arm body, a sliding block 16, a support plate 17, and a front and rear drive assembly. A guide rail 20 and a connector 22 are mounted on the bottom side of the support plate 17, and the front and rear drive assembly is mounted on the top side of the support plate 17. The swing arm body is mounted on the front and rear drive assembly via the sliding block 16. Multiple wire clamps 1 are arranged side-by-side on the swing arm body. The front and rear drive assembly is used to drive the swing arm body to move back and forth in the front-rear direction to simultaneously adjust the front and rear positions of all wire harnesses 2. Specifically, the front and rear drive assembly includes a third motor 18 and a lead screw 19 connected to the drive assembly. The third motor 18 drives the lead screw 19 to rotate, thereby causing the sliding block 16 to move back and forth on the lead screw 19 in the front-rear direction, which in turn causes the swing arm body to move back and forth in the front-rear direction to simultaneously adjust the front and rear positions of all wire harnesses 2.

[0044] In this embodiment, the swing arm body includes a fixed plate 7. Multiple mounting positions are arranged side by side on the top side of the fixed plate 7. Each mounting position is provided with a cylinder 8, an assembly rod 9 and a guide seat 11 that cooperate with each other. A slide rail 10 is provided at the bottom of the assembly rod 9. The slide rail 10 and the guide seat 11 slide and cooperate. The cylinder 8 is driven to connect with the assembly rod 9. The wire clamps 1 are installed on the assembly rod 9 one by one. The cylinder 8 drives the assembly rod 9 to move back and forth in the front and back direction to realize the adjustment of the front and back position of the corresponding wire harness 2.

[0045] In this embodiment, each mounting position is provided with multiple guide seats 11, and the multiple guide seats 11 are arranged in the front-back direction to ensure the accuracy and stability of the assembly rod 9 moving back and forth in the front-back direction, thereby improving the processing accuracy and stability of the wire harness 2.

[0046] In this embodiment, the swing arm body also includes a longitudinal swing rod 12. A fixed seat 13 is provided above the rear end of the assembly rod 9. The rear end of the longitudinal swing rod 12 is rotatably mounted on the fixed seat 13. The wire clamp 1 is installed above the front end of the longitudinal swing rod 12. A spring 15 is installed between the front end of the assembly rod 9 and the middle part of the longitudinal swing rod 12. This arrangement allows the front end of the longitudinal swing rod 12 to swing up and down to adjust to different work positions for wire harness 2 processing.

[0047] In this embodiment, the swing arm body also includes an inverted U-shaped protective cover 14. The bottom sides of the protective cover 14 are fixedly installed on the left and right sides of the fixing plate 7, respectively. The wire harness 2 is located above the protective cover 14 and passes through and is clamped in the wire clamp 1. The cylinder 8, the assembly rod 9, the guide seat 11, the longitudinal swing arm 12, and the fixing seat 13 are all located in the cavity formed between the protective cover 14 and the fixing plate 7, thereby achieving a better protective effect.

[0048] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail made to the invention without departing from the spirit and scope of the invention as defined in the appended claims fall within the protection scope of the invention.
