Description

Technical Field

[0001] This utility model relates to the field of machining equipment, specifically to a terminal circumferential angle adjustment mechanism. Background Technology

[0002] Instruments and meters require electrical connections. Therefore, during mechanized wiring operations for these devices, terminals must first be crimped onto the wire harness, and then the wire harness with terminals is gripped and plugged into the corresponding device housing. Because wire harnesses are flexible, they are prone to deformation during gripping, causing terminal misalignment, especially in the circumferential direction, which directly affects the connection between the terminal and the housing. Therefore, the circumferential angle of the terminals needs to be adjusted beforehand. However, adding a rotator directly to the existing gripping mechanism will cause the wire harness position (e.g., vertical or horizontal) to change due to oscillation. Therefore, a structure is needed that allows for circumferential angle adjustment of the terminals while maintaining the wire harness position. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a terminal circumferential angle adjustment mechanism.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A terminal circumferential angle adjustment mechanism includes a sliding block, a clamping driver, and a gripper. The sliding block is movably disposed within an arc-shaped track. The clamping driver is mounted on the sliding block and connected to the gripper to drive the gripper to open and close. The axis of the gripping center of the gripper when it is closed is defined as the clamping axis. The center of the arc-shaped track is located on the clamping axis of the gripper. The sliding block is connected to a sliding driver, which drives the sliding block to slide within the arc-shaped track.

[0005] Furthermore, it also includes a mounting housing on which the arc-shaped track is formed.

[0006] Furthermore, the sliding block includes an arc-shaped slider and an arc-shaped rack connected together. The arc-shaped slider is movably fitted within an arc-shaped track. The arc-shaped rack meshes with a transmission gear set. The transmission gear set is mounted on a mounting housing. The sliding driver drives the transmission gear set.

[0007] Furthermore, the clamping driver is mounted on an arc-shaped rack.

[0008] Furthermore, the arc-shaped track is located on the front side of the mounting housing, the arc-shaped rack protrudes from the front side of the mounting housing, the transmission gear set includes a transmission wheel, a connecting shaft, and a gear. The gear is located on the front side of the mounting housing and meshes with the arc-shaped rack. The transmission wheel is located on the rear side of the mounting housing for connecting to the sliding drive. The connecting shaft is rotatably mounted on the mounting housing and simultaneously connects the transmission wheel and the gear.

[0009] Furthermore, it also includes a front cover, which is fixed to the front side of the mounting housing to cover the gear.

[0010] Furthermore, a stop bar is fixed to the outer periphery of the gear.

[0011] Furthermore, the clamping driver is a clamping cylinder, and the gripper includes two opposing claw portions. The clamping cylinder drives the two claw portions to move the two claw portions closer to each other or further away from each other, thereby causing the gripper to open and close.

[0012] Furthermore, the sliding block includes an arc-shaped slider and an arc-shaped rack. The arc-shaped slider is movably fitted within an arc-shaped track, and the arc-shaped rack meshes with a transmission gear set. The sliding driver drives the transmission gear set.

[0013] Furthermore, pulleys are provided on one of the opposite sidewalls of the arc-shaped track.

[0014] The technical solution provided by this utility model has the following beneficial effects: After the clamping driver drives the jaws to close and clamp the wire harness, the wire harness is positioned on the clamping axis of the jaws. At this time, according to the angle of terminal deflection, the sliding driver drives the sliding block to slide in the arc-shaped track, thereby driving the clamping driver and jaws to swing in a new way around the clamping axis. In this way, the position of the clamped wire harness can remain stationary and only be adjusted by rotation in the circumferential direction to correct the circumferential angle of the terminal. It has the characteristics of simple structure and easy implementation. Attached Figure Description

Detailed Implementation

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0017] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 3 As shown, this embodiment provides a terminal circumferential angle adjustment mechanism, including a sliding block 120, a clamping driver 140, and a clamping jaw 150. The sliding block 120 is movably disposed within an arc-shaped track. Specifically, the arc-shaped track is formed on a mounting housing 110. The clamping driver 140 is mounted on the sliding block 120, thus enabling it to move together with the sliding block 120. The clamping driver 140 is connected to the clamping jaw 150 to drive the clamping jaw 150 to open and close. The axis where the clamping center of the clamping jaw 150 is located when it is closed is defined as the clamping axis, that is, when the clamping jaw 150 clamps the wire harness 1, the wire harness 1 is located on the clamping axis. The center of the arc-shaped track is located on the clamping axis of the clamping jaw 150. The sliding block 120 is connected to a sliding driver (not shown), which drives the sliding block 120 to slide within the arc-shaped track.

[0020] One preferred operating method is as follows: After the clamping driver 140 drives the jaw 150 to close and clamp the wire harness 1, the wire harness 1 is located on the clamping axis of the jaw 150. At this time, according to the deflection angle of the terminal 2, the sliding driver drives the sliding block 120 to slide in the arc-shaped track, thereby driving the clamping driver 140 and the jaw 150 to swing around the clamping axis (i.e. the clamped wire harness 1) as the center. In this way, the position of the clamped wire harness 1 can remain stationary and only be rotated and adjusted in the circumferential direction to correct the circumferential angle of the terminal 2. This method has the characteristics of simple structure and easy implementation.

[0021] Specifically, to detect the deflection angle of terminal 2, the position of terminal 2 can be acquired by an image acquisition device such as a scanner and transmitted to the control system (such as a PLC control system). That is, the output end of the image acquisition device is connected to the control system, and the control system processes the data to obtain the circumferential deflection angle of terminal 2 of the actual wire harness 1. The control end of the control system is connected to the sliding driver, and then the control system controls the sliding driver to achieve precise angle adjustment.

[0022] Furthermore, the sliding block 120 includes an arc-shaped slider 121 and an arc-shaped rack 122 connected to each other. The arc-shaped slider 121 is adapted to the shape of the arc-shaped track. The arc-shaped track is located on the front side of the mounting housing 110. The arc-shaped slider 121 is movably fitted within the arc-shaped track. The arc-shaped rack 122 protrudes from the front side of the mounting housing 110 and meshes with a transmission gear set. The transmission gear set is mounted on the mounting housing 110. Specifically, the transmission gear set includes a transmission wheel 132, a connecting shaft 133, and a gear 131. The gear 131 is located on the front side of the mounting housing 110 and meshes with the arc-shaped rack 122. The transmission wheel 132 is located on the rear side of the mounting housing 110 for connecting to the sliding drive. The connecting shaft 133 is rotatably mounted on the mounting housing 110 and simultaneously connects the transmission wheel 132 and the gear 131. Specifically, the sliding actuator can be a motor, which is connected to the transmission wheel 132 via a belt, thereby driving the gear 131 to rotate. The rotation of the gear 131, through meshing with the arc-shaped rack 133, drives the sliding block 120 to slide within the arc-shaped track.

[0023] Specifically, the combination of gear 131 and arc rack 122 makes the transmission more precise and reliable.

[0024] Specifically, the sliding driver is connected to the transmission wheel 132 located at the rear of the mounting housing 110, and will not affect the operation of the sliding block 120 and the clamping driver 140 at the front.

[0025] The clamping driver 140 is mounted on the arc-shaped rack 122, specifically fixed to the outer end of the arc-shaped rack 122, while the teeth of the arc-shaped rack 122 are located on the lower side and mesh with the gear 131.

[0026] Additionally, a front cover 113 is included, which is fixed to the front side of the mounting housing 110 to cover the gear 131, thus effectively protecting the gear 131 from external factors.

[0027] Furthermore, a stop bar 134 is fixed to the outer periphery of the gear 131. The stop bar 134 is designed to block the gear 131 when it rotates to the point where it contacts the arc-shaped rack 122. This effectively prevents the sliding block 120 from continuing to slide in the current direction and disengaging from the arc-shaped track, thus providing an effective stopping effect.

[0028] Furthermore, the clamping driver 140 is a clamping cylinder, and the gripper 150 includes two opposing gripper portions 151. The clamping cylinder drives the two gripper portions 151 to move closer or further apart in a translational manner, thereby causing the gripper 151 to open and close. That is, when clamping is required, the clamping cylinder drives the two gripper portions 151 to move closer together until the wire harness 1 is clamped, and when releasing is required, the clamping cylinder drives the two gripper portions 151 to move further apart.

[0029] The above discloses one of the preferred embodiments of this application. Of course, in other embodiments, other structures can be used instead. For example, the transmission gear set may not be assembled on the mounting shell 110, or the assembly structure of the mounting shell 110 may not be used. Alternatively, the sliding block 120 in the arc-shaped track can be driven by a rocker arm. Or the clamping driver can use other driving devices that can open and close the gripper 150. For example, when the gripper 150 is a hinged design, the clamping driver 140 drives the two gripper portions 151 to move closer or further apart in a swinging manner, and so on.

[0030] Although the present 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 may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
