Description

Technical Field

[0001] This utility model relates to a positioning device, specifically a terminal positioning device. Background Technology

[0002] Terminals are wiring components used in the power industry. Terminals often refer to wiring terminals, also called wiring terminals. Crimping terminals are accessory products used to achieve electrical connections.

[0003] Terminal crimping is a process that applies pressure to the contact area between the wire and the terminal to shape it, thereby achieving a tight connection.

[0004] In the prior art, when crimping the contact area between the terminal and the wire, the terminal and the wire cannot be effectively positioned, which can easily lead to terminal misalignment, thus affecting subsequent processing and resulting in poor molding effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a terminal positioning device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a positioning platform, positioning blocks and a driving mechanism. The positioning platform is provided with a transverse track for sliding the positioning blocks and a longitudinal track for placing wires. A placement groove for placing terminals is provided at the intersection of the transverse track and the longitudinal track. The driving mechanism is located on the positioning platform and drives two positioning blocks to move towards or away from each other along the transverse track. The two positioning blocks moving towards each other constitute the fixing of the terminals.

[0007] By adopting the above technical solution, the transverse track on the positioning platform allows the positioning blocks to slide, the longitudinal track is used to place the wires, and the placement slot at the intersection of the two fixes the terminals; the drive mechanism drives the two positioning blocks to move towards each other along the transverse track, clamping the terminals to achieve fixation; this structure effectively prevents the terminals from shifting during the crimping process, ensuring precise alignment between the terminals and the wires, thereby improving crimping quality and processing efficiency, and avoiding poor forming caused by unstable positioning. The present invention is further configured such that: the driving mechanism includes a driving box, a double helical screw, a linkage block and a driving motor; the driving box is provided with a receiving cavity; the top of the driving box is provided with a mating track and forms a connection between the receiving cavity and the transverse track; the mating track is opposite to the transverse track; the driving motor drives the double helical screw to rotate within the receiving cavity; the double helical screw has a first threaded portion and a second threaded portion with opposite thread directions; the linkage block is respectively provided on the first threaded portion and the second threaded portion; and the positioning block is provided on the linkage block and forms a positional block that moves in opposite directions or in opposite directions.

[0008] By adopting the above technical solution, the drive motor drives the double helical screw to rotate in the receiving cavity of the drive box. Since the first and second threaded parts of the screw have opposite thread directions, the linkage block moves on the threaded part, thereby pushing the positioning block to slide in opposite directions along the mating track and the transverse track, realizing the clamping or release of the terminal. The double helical screw design simplifies the drive mechanism, makes the positioning block move more synchronously and accurately, improves positioning stability and response speed, and reduces the risk of terminal misalignment caused by asynchrony.

[0009] The present invention is further configured to include a U-shaped block, an L-shaped block, a fixed rod, and a retraction spring. The fixed rod is located on the right side of the drive box, the U-shaped block is slidably mounted on the fixed rod, the retraction spring is sleeved on the fixed rod and located between the U-shaped block and the side wall of the drive box, the L-shaped block is located on the left side of the drive box, and the drive motor is located on the left side of the drive box. The U-shaped block and the L-shaped block form a detachable connection between the drive box and the positioning platform.

[0010] By adopting the above technical solution, the U-shaped block moves towards the direction of the drive box under the action of the retraction spring. The upper side of the U-shaped block abuts against the upper surface of the positioning platform, and the lower side of the U-shaped block abuts against the lower surface of the drive box. On the other side of the drive box, the upper side of the L-shaped block abuts against the upper surface of the positioning platform. This prevents the drive box from moving horizontally or vertically relative to the positioning platform. The positioning block and the horizontal track prevent the drive box from moving vertically relative to the positioning platform.

[0011] The present invention is further configured such that: a sliding hole is provided at the bottom of the U-shaped block, and the fixing rod passes through the sliding hole to form a sliding motion of the U-shaped block on the fixing rod.

[0012] The present invention is further configured such that: the linkage block is provided with a threaded groove, and the positioning block is provided with a threaded rod, the threaded rod and the threaded groove forming a detachable connection between the linkage block and the positioning block.

[0013] By adopting the above technical solution, the threaded groove on the linkage block is screwed onto the threaded rod on the positioning block, realizing a detachable connection between the linkage block and the positioning block. When the drive mechanism operates, the threaded connection transmits power to move the positioning block. At the same time, when it is necessary to remove the drive box from the positioning platform, the positioning block is first removed from the linkage block to avoid the presence of the positioning block affecting its removal. The detachable design facilitates the replacement of positioning blocks of different sizes to adapt to diverse terminal types and enhance the versatility of the device. Meanwhile, the threaded connection ensures reliable power transmission and prevents positioning failure caused by loosening of the positioning block.

[0014] The present invention is further configured such that: the drive box includes a box body and a box cover, the box cover is detachably mounted on the box body, and a track is mounted on the box cover.

[0015] By adopting the above technical solution, the drive box consists of a box body and a detachable box cover, with a track set on the box cover; removing the box cover allows direct access to components such as the double helical screw inside the receiving cavity; the detachable box cover simplifies internal cleaning and component maintenance, reducing mechanism jamming caused by dust accumulation; the track integrated on the box cover facilitates replacement or adjustment, improving the long-term reliability and maintainability of the drive mechanism.

[0020] like Figure 1-3As shown, this utility model discloses a terminal positioning device, including a positioning platform 1, positioning blocks 2, and a driving mechanism 3. The positioning platform 1 is provided with a transverse track 11 for sliding the positioning blocks 2 and a longitudinal track 12 for placing wires. A placement groove 13 for placing terminals is provided at the intersection of the transverse track 11 and the longitudinal track 12. The driving mechanism 3 is disposed on the positioning platform 1 and drives the two positioning blocks 2 to move towards each other or away from each other along the transverse track 11. The two positioning blocks 2 moving towards each other constitute the fixing of the terminals. The transverse track 11 on the positioning platform 1 allows the positioning blocks 2 to slide, and the longitudinal track 12 is used to place wires. The placement groove 13 at the intersection of the two fixes the terminals. The driving mechanism 3 drives the two positioning blocks 2 to move towards each other along the transverse track 11 to clamp the terminals to achieve fixing. This structure effectively prevents the terminals from shifting during the crimping process, ensures that the terminals and wires are accurately aligned, thereby improving the crimping quality and processing efficiency, and avoiding poor forming caused by unstable positioning. The drive mechanism 3 includes a drive box 31, a double helical screw 32, a linkage block 33, and a drive motor 34. The drive box 31 has a receiving cavity 35. A mating track 36 is provided on the top of the drive box 31, connecting the receiving cavity 35 to the transverse track 11. The mating track 36 is opposite to the transverse track 11. The drive motor 34 drives the double helical screw 32 to rotate within the receiving cavity 35. The double helical screw 32 has a first threaded portion 321 and a second threaded portion 322 with opposite thread directions. The linkage block 33 is respectively disposed on the first threaded portion 321 and the second threaded portion 322. A positioning block 2 is disposed on the linkage block 33. The moving block 33 forms the positioning block 2, which moves in opposite directions. The drive motor 34 drives the double helical screw 32 to rotate in the receiving cavity 35 of the drive box 31. Since the first threaded part 321 and the second threaded part 322 of the screw have opposite thread directions, the linkage block 33 moves on the threaded part, thereby pushing the positioning block 2 to slide in opposite directions along the mating track 36 and the transverse track 11, realizing the clamping or release of the terminal. The design of the double helical screw 32 simplifies the drive mechanism 3, makes the movement of the positioning block 2 more synchronous and accurate, improves the positioning stability and response speed, and reduces the risk of terminal misalignment caused by asynchrony.

[0021] The drive box 31 includes a U-shaped block 4, an L-shaped block 41, a fixing rod 42, and a retraction spring 43. The fixing rod 42 is located on the right side of the drive box 31. The U-shaped block 4 is slidably mounted on the fixing rod 42. The retraction spring 43 is sleeved on the fixing rod 42 and located between the U-shaped block 4 and the side wall of the drive box 31. The L-shaped block 41 is located on the left side of the drive box 31. The drive motor 34 is located on the left side of the drive box 31. The U-shaped block 4 and the L-shaped block 41 form a detachable connection between the drive box 31 and the positioning platform 1. The U-shaped block 4... Under the action of the compression spring 43, it moves in the direction of the drive box 31. The upper side of the U-shaped block 4 abuts against the upper surface of the positioning platform 1, and the lower side of the U-shaped block 4 abuts against the lower surface of the drive box 31. On the other side of the drive box 31, the upper side of the L-shaped block 41 abuts against the upper surface of the positioning platform 1. This prevents the drive box 31 from moving horizontally or vertically relative to the positioning platform 1. The positioning block 2 and the horizontal track 11 prevent the drive box 31 from moving vertically relative to the positioning platform 1.

[0022] The bottom of the U-shaped block 4 is provided with a sliding hole 44, and the fixing rod 42 passes through the sliding hole 44 to form the sliding of the U-shaped block 4 on the fixing rod 42.

[0023] The linkage block 33 is provided with a threaded groove 37, and the positioning block 2 is provided with a threaded rod 38. The threaded rod 38 and the threaded groove 37 form a detachable connection between the linkage block 33 and the positioning block 2. The threaded groove 37 on the linkage block 33 and the threaded rod 38 on the positioning block 2 are screwed together to realize the detachable connection between the linkage block 33 and the positioning block 2. When the drive mechanism 3 operates, the threaded connection transmits power to move the positioning block 2. At the same time, when it is necessary to remove the drive box 31 from the positioning platform 1, the positioning block 2 is first removed from the linkage block 33 to avoid the presence of the positioning block 2 affecting its removal. The detachable design makes it easy to replace the positioning block 2 of different sizes to adapt to diverse terminal types and enhance the versatility of the device. At the same time, the threaded connection ensures reliable power transmission and prevents positioning failure caused by loosening of the positioning block 2.

[0024] The drive box 31 includes a box body 311 and a box cover 312. The box cover 312 is detachably mounted on the box body 311 and is mounted on the box cover 312 with a matching track 36. The drive box 31 consists of the box body 311 and the detachable box cover 312, with the matching track 36 mounted on the box cover 312. Removing the box cover 312 allows direct access to components such as the double helical screw 32 inside the receiving cavity 35. The detachable box cover 312 simplifies internal cleaning and component maintenance, reducing mechanism jamming caused by dust accumulation. The matching track 36 is integrated into the box cover 312, facilitating replacement or adjustment and improving the long-term reliability and maintainability of the drive mechanism 3.

[0025] Working principle: The horizontal track 11 of the positioning platform 1 allows the positioning block 2 to slide, and the vertical track 12 places the wire. The placement slot 13 at the intersection of the two fixes the terminal. The drive motor 34 of the drive mechanism 3 drives the double helical screw 32 to rotate. Through the first and second threaded parts 322 with opposite thread directions, the linkage block 33 is driven to move synchronously in opposite directions, pushing the positioning block 2 to clamp or release the terminal along the horizontal track 11. The drive box 31 is detachably installed on the positioning platform 1 through the U-shaped block 4 and the L-shaped block 41, while the positioning block 2 is detachably connected to the threaded groove 37 of the linkage block 33 through the threaded rod 38. The detachable design of the box cover 312 facilitates the maintenance of the internal components.
