Description

Technical Field

[0001] This application relates to the technical field of wire harness processing, and in particular to a clamping and ejection structure for a wire terminal crimping machine. Background Technology

[0002] Wire harnesses are used to connect input and output terminals for electrical or signal transmission. They are widely used in various live devices and equipment. To facilitate connection, wire harnesses usually have terminals at their ends. During the processing of wire harnesses, terminals need to be crimped to the ends of the wire harnesses using a crimping device.

[0003] However, in the existing wire harness terminal crimping device, the wire harness and terminal are crimped together by a crimping mechanism during the production process. After crimping, the crimped wire harness is held by a clamping arm on a transfer mechanism. After clamping, the wire harness is placed in a collection trough for collection. However, the existing transfer mechanism usually adopts a three-axis movement method to change the position of the clamping arm, which is complex and has low wire harness output efficiency. Therefore, further improvement is needed. Utility Model Content

[0004] To address the above problems, this application provides a clamping and ejection structure for an electrical wire terminal crimping machine.

[0005] This application provides a clamping and discharging structure for a wire terminal crimping machine, which adopts the following technical solution: A clamping and discharging structure for a wire terminal crimping machine includes a frame, a horizontal clamping mechanism mounted on the frame for clamping and horizontally moving a wire harness, and a steering clamping mechanism for turning the wire harness clamped by the horizontal clamping mechanism. The frame is provided with a first mounting bracket for rotatably connecting the steering clamping mechanism. The steering clamping mechanism includes a swing arm mounted on the first mounting bracket, a first rotating shaft fixedly connected to one end of the swing arm, a second clamping assembly connected to the other end of the swing arm for clamping the wire harness, and a second driving assembly for driving the first rotating shaft to rotate. The second clamping assembly is located below the swing arm.

[0006] By adopting the above technical solution, the horizontal clamping mechanism can clamp and move the wire harness in the horizontal direction, facilitating the transfer of the crimped wire harness from the crimping position. The swing arm in the steering clamping mechanism is mounted on the first mounting bracket. When the second drive assembly drives the first rotating shaft to rotate, the swing arm rotates accordingly, thereby driving the second clamping assembly located below the swing arm to rotate, realizing the steering operation of the wire harness clamped by the horizontal clamping mechanism. Compared with the three-axis steering in the prior art, this method is relatively simpler and can effectively improve the wire harness output efficiency.

[0007] Preferably, the steering clamping mechanism includes a third drive component for driving the second clamping component to rotate, wherein the rotation direction of the second clamping component is opposite to the rotation direction of the first rotating shaft, and is arranged parallel to the clamping position of the horizontal clamping mechanism.

[0008] By adopting the above technical solution, the steering clamping mechanism is equipped with a third drive component for driving the second clamping component to rotate, so that the rotation direction of the second clamping component is opposite to the rotation direction of the first rotating shaft and is set parallel to the clamping position of the horizontal clamping mechanism. This allows for more flexible transfer and adjustment of the wire harness from the horizontal clamping mechanism to a suitable position, improving the convenience and accuracy of position adjustment during the wire harness discharge process, thereby increasing the discharge efficiency of the wire terminal crimping machine and reducing the space occupied by the wire harness falling into the collection trough.

[0009] Preferably, the third drive assembly includes a first pulley and a second pulley rotatably connected to both ends of the swing arm, a first synchronous belt wound around the first pulley and the second pulley, and a drive member that drives the first pulley to rotate. The rotation direction of the first pulley is opposite to the rotation direction of the first rotating shaft. The second pulley is fixedly connected to the second rotating shaft, and the second rotating shaft is connected to the second clamping assembly.

[0010] By adopting the above technical solution, the first pulley and the second pulley of the third drive component are rotatably connected to both ends of the swing arm and connected by the first synchronous belt. When the drive component drives the first pulley to rotate, since the rotation direction of the first pulley is opposite to the rotation direction of the first shaft, and the second shaft fixedly connected to the second pulley is connected to the second clamping component, the rotation direction of the second clamping component can be opposite to the rotation direction of the first shaft. This achieves parallel clamping positions of the second clamping component and the horizontal clamping mechanism, ensuring smooth turning and efficient discharge of the wire harness.

[0011] Preferably, the first mounting bracket is provided with a second mounting bracket, and the second drive assembly includes a drive motor fixedly connected to the upper surface of the second mounting bracket, a first drive gear fixedly sleeved with the output shaft of the drive motor, and a first driven gear meshing with the first drive gear, wherein the first driven gear is coaxially fixedly sleeved on the first rotating shaft.

[0012] By adopting the above technical solution, the first driving gear is driven to rotate by the drive motor, and the first driven gear meshing with it rotates, thereby causing the first rotating shaft coaxially fixed to the first driven gear to rotate, realizing the rotation of the swing arm, providing power for the steering action of the steering clamping mechanism. The structure is simple and can effectively realize the steering and discharge of the wire harness, improving the wire harness discharge efficiency.

[0013] Preferably, the driving component includes a second driving gear coaxially sleeved on the output shaft of the drive motor, an auxiliary gear meshing with the second driving gear, and a second driven gear meshing with the auxiliary gear, wherein the second driven gear is fixedly connected to the first pulley.

[0014] By adopting the above technical solution, the power is transmitted to the first pulley by the cooperation of the second driving gear, the auxiliary gear and the second driven gear on the output shaft of the drive motor, so as to drive the first pulley to rotate, and then drive the second pulley and the second shaft to rotate, so as to make the second clamping component rotate, meet the steering requirements, and the structure is simple and can effectively improve the wire harness output efficiency.

[0015] Preferably, the first mounting bracket is provided with a second mounting bracket, and the second drive assembly includes a drive motor fixedly connected to the upper surface of the second mounting bracket, a third pulley fixedly sleeved with the output shaft of the drive motor, a fourth pulley fixedly sleeved with the first rotating shaft, and a second synchronous belt wound around the third pulley and the fourth pulley.

[0016] By adopting the above technical solution, the third pulley is driven by a drive motor to rotate, and the fourth pulley is driven to rotate by the second synchronous belt, which in turn drives the first rotating shaft to rotate, thereby realizing the rotation of the steering clamping mechanism. The structure is simple and can effectively improve the wire harness output efficiency.

[0017] Preferably, the driving component includes a third driving gear coaxially sleeved on the output shaft of the drive motor and a third driven gear meshing with the third driving gear, the third driven gear being fixedly connected to the first pulley.

[0018] By adopting the above technical solution, in the case of the second drive assembly consisting of the third pulley, the fourth pulley, the second synchronous belt and the drive motor, the following drive components are set accordingly. By using the third driving gear coaxially sleeved on the output shaft of the drive motor and the meshing third driven gear, the first pulley can be driven to rotate, thereby realizing the rotation of the second clamping assembly, making the structure more compact and effectively improving the output efficiency of the wire terminal crimping machine.

[0019] Preferably, the second mounting bracket is provided with a cover.

[0020] By adopting the above technical solution, a cover is installed outside the second mounting frame to protect the components inside the second mounting frame, reduce damage and interference to the components from external factors, and ensure the stable operation of the clamping and discharging structure.

[0021] In summary, this application has the following beneficial effects: By combining horizontal clamping and steering clamping mechanisms, the use of three-axis movement is reduced, simplifying the structure, lowering equipment manufacturing costs, and improving wire harness output efficiency, thus meeting the demands of modern industry for high-efficiency production.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0025] This application discloses a clamping and ejection structure for a wire terminal crimping machine.

[0026] Example 1: A clamping and discharging structure for a wire terminal crimping machine, as described in the following figure. Figure 1 , Figure 2 It includes a frame 1, a horizontal clamping mechanism 2 mounted on the frame 1 for clamping the wire harness for horizontal movement, and a turning clamping mechanism 3 for turning the wire harness clamped by the horizontal clamping mechanism 2.

[0027] The horizontal clamping mechanism 2 specifically includes a sliding seat 21 slidably connected to the frame 1, a first clamping component 22 located on the sliding seat 21, and a first driving component 23 that drives the first clamping component 22 to move along the length direction of the sliding seat 21. The first driving component 23 can be driven by a cylinder or by a drive motor 341 and a lead screw, depending on the requirements. The first clamping component 22 is a pneumatic gripper or an electric gripper. Since this is existing technology, it will not be described in detail here.

[0028] The frame 1 is provided with a first mounting bracket 11 for the rotatable connection of the steering clamping mechanism 3. The steering clamping mechanism 3 includes a swing arm 31 mounted on the first mounting bracket 11, a first rotating shaft 32 fixedly connected to one end of the swing arm 31, a second clamping assembly 33 connected to the other end of the swing arm 31 for clamping the wire harness, a second driving assembly 34 for driving the first rotating shaft 32 to rotate, and a third driving assembly 4 for driving the second clamping assembly 33 to rotate. The second clamping assembly 33 is located below the swing arm 31.

[0029] One end of the swing arm 31 is rotatably connected to the first mounting bracket 11 via a bearing, which can be a deep groove ball bearing, to ensure the smooth rotation of the first rotating shaft 32. The first rotating shaft 32 is fixedly connected to the upper surface of the swing arm 31, and the second clamping assembly 33 is connected to the other end of the swing arm 31 and located below the swing arm 31, for clamping the wire harness. The second clamping assembly 33 can also adopt a claw structure similar to the horizontal clamping mechanism 2. The second drive assembly 34 is used to drive the first rotating shaft 32 to rotate, thereby driving the swing arm 31 to rotate and realize the direction of the wire harness.

[0030] The first mounting bracket 11 is provided with a second mounting bracket 12 for mounting the second drive assembly 34. The second drive assembly 34 specifically includes a drive motor 341 fixedly connected to the upper surface of the second mounting bracket 12, a first drive gear 342 fixedly sleeved with the output shaft of the drive motor 341, and a first driven gear 343 meshing with the first drive gear 342. The first driven gear 343 is coaxially fixedly sleeved on the first rotating shaft 32.

[0031] The third drive assembly 4 is used to drive the second clamping assembly 33 to rotate. The rotation direction of the second clamping assembly 33 is opposite to the rotation direction of the first rotating shaft 32, and is arranged parallel to the clamping position of the horizontal clamping mechanism 2. In this embodiment, the third drive assembly 4 includes a first pulley 41 and a second pulley 42 respectively rotatably connected to both ends of the swing arm 31, a first synchronous belt 43 wound around the first pulley 41 and the second pulley 42, and a drive member 44 that drives the first pulley 41 to rotate. The rotation direction of the first pulley 41 is opposite to the rotation direction of the first rotating shaft 32. The second pulley 42 is fixedly connected to the second rotating shaft 5, and the second rotating shaft 5 is connected to the second clamping assembly 33.

[0032] Reference Figure 2 , Figure 3The driving component 44 includes a second driving gear 441 coaxially mounted on the output shaft of the drive motor 341, an auxiliary gear 442 meshing with the second driving gear 441, and a second driven gear 443 meshing with the auxiliary gear 442. The second driven gear 443 is fixedly connected to the first pulley 41. When the drive motor 341 starts, it drives the first pulley 41 to rotate through a series of gear transmissions, and then drives the second pulley 42 to rotate through the first synchronous belt 43, thereby causing the second clamping assembly 33 to rotate and be arranged parallel to the clamping position of the horizontal clamping mechanism 2. If pulley and synchronous belt transmission are not used, gear transmission or chain transmission can also be used.

[0033] Furthermore, the second mounting bracket 12 is provided with a cover 13, which is used to protect the internal drive components and other parts, and prevent dust, debris and other objects from entering and affecting the normal operation of the equipment.

[0034] The implementation principle of the clamping and discharging structure for a wire terminal crimping machine according to this application embodiment is as follows: This embodiment simplifies the structure and reduces manufacturing costs and maintenance difficulty compared to the traditional three-axis movement method through the cooperation of the horizontal clamping mechanism 2 and the steering clamping mechanism 3. The horizontal clamping mechanism 2 enables the horizontal movement of the wire harness, the steering clamping mechanism 3 enables the steering of the wire harness, and the second clamping component 33 is rotated by the third drive component 4, ensuring smooth wire harness discharging and improving wire harness discharging efficiency. This represents a significant improvement and enhancement compared to existing technologies.

[0035] Example 2: Reference Figure 4 The difference from Embodiment 1 is that, in this embodiment, the second drive assembly 34 includes a drive motor 341 fixedly connected to the upper surface of the second mounting bracket 12, a third pulley 344 fixedly sleeved with the output shaft of the drive motor 341, a fourth pulley 345 fixedly sleeved with the first rotating shaft 32, and a second synchronous belt 346 wound around the third pulley 344 and the fourth pulley 345. The drive member 44 includes a third driving gear 444 coaxially sleeved with the output shaft of the drive motor 341 and a third driven gear 445 meshing with the third driving gear 444. The third driven gear 445 is fixedly connected to the first pulley 41. The drive motor 341 drives the third pulley 344 to rotate, which in turn drives the fourth pulley 345 to rotate via the second synchronous belt 346, thereby driving the first rotating shaft 32 to rotate. The third driving gear 444, which is coaxially sleeved on the output shaft of the drive motor 341, and the meshing third driven gear 445 drive the first pulley 41 to rotate. This makes the rotation direction of the second clamping component 33 opposite to the rotation direction of the swing arm 31, thus achieving parallel clamping positions of the second clamping component 33 and the horizontal clamping mechanism 2, ensuring smooth turning and efficient discharge of the wire harness.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
