Description

Technical Field

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

[0002] Metal terminals are made by stamping metal materials. At the factory, the terminals are connected by connecting handles, arranging multiple terminals in a chain-like pattern. They are then rolled into a disc for easy transport and subsequent crimping by a terminal crimping machine. A terminal crimping machine is a machine used in wire processing. It crimps metal terminals to the wire end and then establishes conductivity, stably connecting two wires without soldering. However, a terminal crimping machine needs to be replaced after one disc of terminals is used up. Replacing with new terminals requires pausing the machine and then refeeding the terminals, which is not only cumbersome but also inefficient.

[0003] To facilitate terminal insertion, workers need to weld the ends of the two terminal trays together. However, since the terminal ends are not cut to the same length at the factory, direct welding can easily result in the terminal gap being too long or too short, which may cause the crimping machine to get stuck, affecting work efficiency and even damaging the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a cutting device that can accurately cut the welding ends of two terminals so that the terminal gap at the welding point meets the requirements after the two terminals are welded together.

[0005] The technical solution of this utility model is to provide a terminal cutting device having the following structure:

[0006] The device includes a workbench and positioning seats and a cutting assembly mounted on the workbench. Two positioning seats are symmetrically and spaced apart on the workbench. Each positioning seat has a cutting positioning boss connected to it. The upper end of each cutting positioning boss is trapezoidal, wider at the bottom and narrower at the top, fitting into the recessed portion of a terminal for placement. Each of the two cutting positioning bosses has a positioning plate at its facing end, which abuts against the sidewall of the terminal. The cutting assembly is positioned between the two positioning seats and is used to cut terminals extending beyond the positioning plates.

[0007] After adopting the above structure, the terminal cutting device of this utility model has the following advantages compared with the prior art:

[0008] The terminal is placed on the cutting and positioning boss, with the side wall of the terminal abutting against the positioning plate. Then, the terminal extending beyond the positioning plate is cut by the cutting assembly. The positioning effect of the cutting and positioning boss and the positioning plate ensures that the cut terminal meets the welding requirements, ensuring that the terminal gap size at the welding point remains unchanged. This avoids affecting the operation of the crimping machine due to excessively large or small terminal gaps, improving efficiency and preventing equipment damage. In addition, the upper end of the cutting and positioning boss matches the recessed part of the terminal, preventing the terminal from deforming during cutting.

[0009] Preferably, the cutting assembly includes a drive motor and two cutting blades. The drive motor is fixedly connected to the worktable, and the cutting blades are connected to the output shaft of the drive motor. The drive motor is used to drive the cutting blades to move vertically up and down to cut the terminals extending out of the positioning plate.

[0010] Preferably, a counterweight is connected to the output shaft of the drive motor above the cutting blade. The counterweight has two through holes extending through its upper and lower ends. A counterweight block is located above the counterweight block, and two pressure blocks adapted to the through holes are connected to the bottom of the counterweight block. The lower ends of the two pressure blocks pass through the corresponding through holes and are located outside the two cutting blades, used to press the corresponding terminals firmly onto the cutting positioning boss. When cutting the terminals, the output shaft of the drive motor descends, and the pressure blocks press against the terminals, preventing terminal misalignment and ensuring that the cut dimensions meet requirements.

[0011] Preferably, the positioning seat has a receiving groove extending along its length and penetrating both ends. The side wall of the positioning seat has a threaded hole communicating with the receiving groove, and a bolt is threaded into the threaded hole. The lower end of the cutting positioning boss is positioned within the receiving groove, and the connecting end of the bolt extends into the receiving groove and abuts against the side wall of the cutting positioning boss, thus fixing the cutting positioning boss in the receiving groove. With this configuration, the user can adjust the position of the cutting positioning boss and the positioning plate (the positioning plate is fixedly connected to the end of the cutting positioning boss) according to actual conditions to ensure the cutting dimensions meet requirements.

[0012] Preferably, the cutting positioning boss has a notch in the middle, and a limiting plate is connected to the notch to lock into the terminal gap, so as to prevent the terminal on the cutting positioning boss from axial displacement and thus avoid cutting failure.

[0013] Preferably, the top of the limiting plate is provided with a groove for the terminal connecting handle to be inserted.

[0014] Preferably, a waste inlet is provided on the worktable between the two positioning seats, and a downwardly inclined waste trough is connected to the waste inlet for conveying the cut waste to the waste frame below. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, 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. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-3 As shown, this utility model discloses a terminal cutting device, which includes a workbench 1, a positioning seat 2 and a cutting component 3 disposed on the workbench 1.

[0023] There are two positioning seats 2, which are symmetrically and spaced apart on the worktable 1. A cutting positioning boss 4 is connected to the positioning seat 2. The upper end of the cutting positioning boss 4 is a trapezoid with a smaller upper end and a larger lower end, which fits into the recess of the terminal 6 and is used to place the terminal 6. A positioning plate 5 is provided at the opposite end of the two cutting positioning bosses 4, which is used to abut against the side wall of the terminal 6. The cutting component 3 is arranged between the two positioning seats 2 and is used to cut the terminal 6 that extends out of the positioning plate 5.

[0024] The cutting assembly 3 includes a drive motor 31 and two cutting blades 32. The drive motor 31 is fixedly connected to the worktable 1, and the cutting blades 32 are connected to the output shaft of the drive motor 31. The drive motor 31 is used to drive the cutting blades 32 to move vertically up and down to cut the terminals 6 that extend out of the positioning plate 5.

[0025] A counterweight 33 is connected to the output shaft of the drive motor 31 above the cutting blade 32. The counterweight 33 has two through holes extending through its upper and lower ends. A counterweight block 34 is located above the counterweight 33. Two pressure blocks 35, which are adapted to the through holes, are connected to the bottom of the counterweight block 34. The lower ends of the two pressure blocks 35 pass through the corresponding through holes (sliding fit) and are located outside the two cutting blades 32, used to press the corresponding terminals 6 onto the cutting positioning boss 4. When cutting the terminals 6, the output shaft of the drive motor 31 descends, and the pressure blocks 35 press against the terminals 6, which can prevent the terminals 6 from shifting and ensure that the cutting dimensions meet the requirements.

[0026] In this invention, when cutting the terminal 6, the terminal 6 is simply placed on the cutting positioning boss 4, with its sidewall abutting against the positioning plate 5. Then, the cutting blade 32 and two pressure blocks 35 are driven downward by the drive motor 31. The pressure blocks 35, relying on the weight of the counterweight 34, press the terminal 6 firmly onto the cutting positioning boss 4. The cutting blade 32 continues to press downward under the drive of the drive motor 31, cutting the terminal 6 extending beyond the positioning plate 5. Through the positioning effect of the cutting positioning boss 4 and the positioning plate 5, the cut terminal 6 meets the welding requirements, ensuring that the terminal gap 61 at the welding point remains unchanged. This avoids affecting the operation of the terminal crimping machine due to the terminal gap 61 being too large or too small, improving efficiency and preventing equipment damage. In addition, since the upper end of the cutting positioning boss 4 matches the recessed part of the terminal 6, deformation of the terminal 6 during cutting can be prevented.

[0027] The positioning seat 2 has a receiving groove 21 extending along its length and penetrating both ends. The side wall of the positioning seat 2 has a screw hole 22 that communicates with the receiving groove 21. A bolt is threaded onto the screw hole 22. The lower end of the cutting positioning boss 4 is set in the receiving groove 21. The connecting end of the bolt extends into the receiving groove 21 and abuts against the side wall of the cutting positioning boss 4, which is used to fix the cutting positioning boss 4 in the receiving groove 21. In this way, the user can adjust the position of the cutting positioning boss 4 and the positioning plate 5 (the positioning plate 5 is fixedly connected to the end of the cutting positioning boss 4) according to the actual situation so that the cutting size meets the requirements.

[0028] The cutting positioning boss 4 has a notch in the middle, and a limiting plate 7 is connected to the notch to lock into the terminal gap 61, preventing the terminal 6 on the cutting positioning boss 4 from axial displacement, thereby avoiding cutting failure. The top of the limiting plate 7 also has a groove 71 for the terminal connecting handle 62 to be locked in.

[0029] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
