Description

Technical Field

[0001] This utility model relates to the field of terminal crimping detection technology, specifically a terminal crimping height detection device. Background Technology

[0002] During the wire-terminal crimping process, the crimping height needs to be measured to determine the quality of the crimping between the wire and the terminal. The crimping height is the height of the crimping terminal pressed onto the wire core. If the crimping height is too large, the crimping terminal may not be fully crimped onto the core, potentially leading to poor conductivity between the crimping terminal and the core. If the crimping height is too small, the core inside the crimping terminal may be cut off, both of which will affect the circuit conductivity between the wire and the terminal.

[0003] A height detection device is required during terminal crimping. Chinese utility model patent CN216523562U discloses a terminal crimping height detection device, including a base and a digital micrometer. The base has a U-shaped groove in the middle, and the digital micrometer is mounted on the top of the base with its probe extending vertically into the U-shaped groove. An upper probe is installed at the bottom of the probe of the digital micrometer. A lower probe is installed at the bottom of the U-shaped groove on the base, located below the upper probe, with its top shaped like a frustum. This detection device, using a digital micrometer, ensures the accuracy of crimping height measurement, reduces the contact area between the upper and lower probes and the crimped terminal, allows the upper and lower probes to avoid interference points on the crimped terminal, improves the flatness between the measuring probe and the contact surface of the crimped terminal, reduces measurement errors, improves measurement results, and helps to accurately determine the crimping status between the wire and the terminal.

[0004] However, this utility model can only detect and process a single wire terminal during use, and cannot detect multiple wire terminals simultaneously, which affects the detection efficiency and cannot meet production needs. Therefore, a terminal crimping height detection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a terminal crimping height detection device, which has the advantage of being able to detect multiple terminals simultaneously. This solves the problem that existing height detection devices can only detect a single wire terminal and cannot detect multiple wire terminals at the same time, thus affecting detection efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a terminal crimping height detection device, comprising a workbench and a top plate disposed on the top of the workbench, wherein a support column is fixedly connected between the top plate and the workbench, and a synchronous clamping mechanism capable of clamping multiple terminals is disposed on the top of the workbench.

[0007] The synchronous clamping mechanism includes a mounting box fixedly connected to the top of the workbench. A first electric push rod and a second electric push rod extending into the mounting box are fixedly connected to the left and right sides of the mounting box, respectively. A first movable rod and a second movable rod are fixedly connected to the output ends of the first electric push rod and the second electric push rod, respectively. A long clamping plate extending to the top of the mounting box is fixedly connected to the outside of the first movable rod, and a short clamping plate extending to the top of the mounting box is fixedly connected to the outside of the second movable rod.

[0008] Furthermore, the second movable rod passes through the long clamping plate and is slidably connected to it, and the lengths of the first and second movable rods are equal.

[0009] Furthermore, the mounting box has two fixedly connected positioning plates inside, and both positioning plates are slidably connected to the first movable rod and the second movable rod.

[0010] Furthermore, there are five long clamping plates and five short clamping plates, and an arc-shaped groove is provided on the opposite side of each of the long clamping plates and the short clamping plates.

[0011] Furthermore, a placement platform is fixedly connected to the top of the mounting box, and a material feeding groove adapted to the long clamping plate and the short clamping plate is opened on the upper surface of the placement platform.

[0012] Furthermore, a telescopic cylinder extending to the bottom of the top plate is fixedly connected to the top of the top plate, and a connecting plate is fixedly connected to the output end of the telescopic cylinder. A laser height measuring instrument is fixedly connected to the side of the connecting plate near the mounting box.

[0013] Furthermore, the number of laser height measuring instruments is the same as the number of long clamping plates. The laser height measuring instruments are located directly above the long clamping plates and the short clamping plates. A positioning guide rod that penetrates the top plate is fixedly connected to the top of the connecting plate.

[0014] Furthermore, the bottom of the workbench is rotatably connected to four casters, which are evenly distributed on the bottom of the workbench.

[0015] Compared with the prior art, the present invention provides a terminal crimping height detection device, which has the following advantages:

[0016] 1. This terminal crimping height detection device, by setting a first electric push rod and a second electric push rod, enables the first electric push rod and the second electric push rod to move respectively. At this time, the first and second electric push rods drive the long clamping plate and the short clamping plate to move respectively, thereby facilitating the clamping and fixing of the terminal. At the same time, since there are five long clamping plates, it is possible to fix multiple terminals at the same time, which greatly improves the detection efficiency.

[0017] 2. This terminal crimping height detection device uses a telescopic cylinder to move a connecting plate downwards, which in turn moves a laser height measuring instrument downwards. The laser height measuring instrument can then simultaneously detect the height of multiple terminals, solving the problem that existing height detection devices can only detect a single wire terminal and cannot detect multiple wire terminals simultaneously, thus affecting detection efficiency.

[0027] It should be noted that in the technical solution of this application, the output ends of the first electric push rod 5 and the second electric push rod 7 can be extended and retracted simultaneously by using a synchronization controller or synchronization valve, thereby achieving synchronous operation.
