However, it hinders the rapid positioning and bending of the terminals, reducing the accuracy and efficiency of the processing. Therefore, we provide a terminal positioning and bending fixture to solve these problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution for a terminal positioning and bending fixture.

[0026] like Figure 1 - Figure 4 As shown, the device includes a working platform 1, and a support frame 2 is fixedly connected to the top surface of the working platform 1. The working platform 1 and the support frame 2 provide support for the installation and use of other components of the device, making it convenient for workers to use the device to position and bend terminals, improving the ease of use of the device and speeding up the bending operation.

[0027] Above the work platform 1 are a bending work plate 3 and a positioning work plate 4. The bending work plate 3 and the positioning work plate 4 are fixedly connected to two lifting columns 604 respectively. The bottom surfaces of the bending work plate 3 and the positioning work plate 4 are equipped with flexible rubber buffer blocks, which can prevent the device from causing wear on the terminal surface during the positioning and bending operations, avoid metal scratches or metal fatigue on the terminal surface, and extend the service life of the product. The operator can control the lifting and lowering of the bending work plate 3 and the positioning work plate 4 through two drive mechanisms 6 to perform terminal positioning and bending operations.

[0028] Two sets of limiting posts 5 are fixedly connected to the top surface of the work platform 1. The bending work plate 3 and the positioning work plate 4 slide on the surface of the limiting posts 5. When the positioning work plate 4 descends to contact the pressing plate 8, it can press and fix the terminal. The bending work plate 3 can bend the terminal during the descent. The limiting posts 5 can provide limiting and support for the lifting of the bending work plate 3 and the positioning work plate 4, improve the accuracy of the device in the positioning and bending of the terminal, and enhance the production consistency of the product.

[0029] Each limiting post 5 is fitted with a return spring 7 on its outer surface. Each return spring 7 is fixedly connected to the working platform 1. The end of each return spring 7 is fixedly connected to the corresponding bending working plate 3 or positioning working plate 4. The return spring 7 provides a certain buffering effect for the descent of the bending working plate 3 and the positioning working plate 4, avoiding the bending working plate 3 and the positioning working plate 4 from causing a large impact on the terminals when positioning and bending the terminals, reducing the risk of damage to the terminals during processing. The return spring 7 can also provide a certain power for the upward reset of the bending working plate 3 and the positioning working plate 4, reducing the workload of manual reset by the workers.

[0030] A pressure plate 8 is fixedly connected to the top surface of the work platform 1. A movable plate 9 is provided on the outside of the pressure plate 8. Both the pressure plate 8 and the movable plate 9 are made of SPCC cold-rolled steel plate, which has good ductility properties and can reduce the damage to the terminal surface during bending and pressing. The top surfaces of the pressure plate 8 and the movable plate 9 are provided with placement slots. The operator first places the terminal to be processed in the slots on the top surfaces of the pressure plate 8 and the movable plate 9. Then, the positioning work plate 4 and the bending work plate 3 are controlled to descend by the drive mechanism 6. After the positioning work plate 4 descends to a certain position, its bottom buffer block can press and fix the terminal. After the bending work plate 3 descends to a certain position, it can squeeze the terminal, thereby bending the terminal under force to achieve the purpose of bending the terminal.

[0031] A set of buffer springs 10 are fixedly installed on the bottom surface of the movable plate 9. The end of each buffer spring 10 away from the movable plate 9 is fixedly connected to the working platform 1. When the bending working plate 3 descends to the point where its bottom buffer block contacts the movable plate 9, the movable plate 9 will compress the buffer springs 10 as the bending working plate 3 continues to descend, thereby providing space for the bending terminals of the bending working plate 3. The buffer springs 10 include multiple springs evenly arranged below the movable plate 9, which can provide a relatively stable support effect for the movable plate 9. The small amplitude sway caused by the characteristics of the springs themselves usually does not affect the bending terminals of the bending working plate 3 after the bending operation is completed.

[0032] The support frame 2 is externally equipped with two drive mechanisms 6. The drive mechanism 6 includes a fixing plate 601 that is fixedly connected to the support frame 2. The surface of the support frame 2 is provided with grooves. The operator can fix the fixing plate 601 to the surface of the support frame 2 with bolts and nuts. The position of the fixing plate 601 can be adjusted according to the actual bending requirements of the terminal, which improves the applicability of the device. The fixing plate 601 provides support for the use of the drive mechanism 6.

[0033] A mounting bracket 602 is fixedly connected to the outer surface of the fixed plate 601. A limiting sleeve 603 is fixedly connected to the bottom end of the mounting bracket 602. A lifting column 604 is slidably connected inside the limiting sleeve 603. The lifting column 604 can drive the corresponding bending working plate 3 or positioning working plate 4 to rise and fall, so that the bending working plate 3 or positioning working plate 4 can perform different processing operations on the terminals. The mounting bracket 602 and the limiting sleeve 603 provide limiting and support effects for the lifting column 604, improving the operation accuracy and stability of the device. The two lifting columns 604 have different lengths, that is, the length of the lifting column 604 connected to the bending working plate 3 is greater than that of the lifting column 604 connected to the positioning working plate 4, so that the bending working plate 3 can perform bending operations on the terminals.

[0034] A drive rod 605 is hinged to the top of the mounting bracket 602 via a pin. A transmission frame 606 is provided outside the drive rod 605. The upper and lower ends of the transmission frame 606 are respectively hinged to the drive rod 605 and the lifting column 604 via pins. A rubber sleeve is installed on the handle of the drive rod 605 to increase the friction between the handle and the palm, reduce the probability of slipping, and protect the operator's hands. The transmission frame 606 includes two symmetrical connecting pieces. When the operator moves the drive rod 605, the drive rod 605 will move in a circular motion around the pin hinged to the top of the mounting bracket 602. At this time, the drive rod 605 can drive the end of the transmission frame 606 to rotate. The transmission frame 606 will then drive the lifting column 604 to slide inside the limiting sleeve 603 under the limiting action of the lifting column 604 and the limiting sleeve 603, thereby driving the bending working plate 3 or the positioning working plate 4 to rise and fall, so as to facilitate the device to position and bend the terminals.

[0035] Working principle: When the operator wants to use this device to bend the terminal, first place the terminal in the groove on the top surface of the clamping plate 8 and the movable plate 9. Then select the drive mechanism 6 connected to the positioning plate 4 and pull the drive rod 605. The drive rod 605 drives the transmission frame 606 to rotate. The rotation of the transmission frame 606 drives the lifting column 604 to descend, thereby driving the positioning plate 4 to descend. After the positioning plate 4 descends to the bottom buffer block to stably clamp the terminal, operate the drive mechanism 6 connected to the bending plate 3 according to the above steps. The bending plate 3 will descend under the action of the drive mechanism 6. When the buffer block on the bottom surface of the bending plate 3 contacts the movable plate 9, the bending plate 3 continues to descend. The movable plate 9 will compress the buffer spring 10 to provide space for the descent of the bending plate 3. During the descent, the bending plate 3 and the movable plate 9 can perform bending operations on the terminal. Finally, reset the two drive rods 605 and remove the terminal from the clamping plate 8.
