Description

Technical Field

[0001] This utility model relates to the field of contactor automatic production technology, specifically to a wire clamping screw positioning tool. Background Technology

[0002] In the field of modern industrial automation control, contactors, as key electrical components, undertake the core function of connecting and disconnecting circuits. Contactors are typically equipped with multiple terminals, and external wires are securely connected to these terminals by mounting wire clamping screws, thereby ensuring the stability and safety of current transmission. With the continuous improvement of industrial automation, the automated installation technology of contactor wire clamping screws has become an important research direction for improving production efficiency and enhancing production consistency.

[0003] Currently, the automated installation of wire clamping screws mainly relies on the collaborative operation of a feeding mechanism and a loading mechanism. The feeding mechanism (such as a vibrator) is responsible for arranging the scattered wire clamping screws in an orderly manner and continuously and stably supplying them to a wire clamping screw positioning tool installed at the output end of the loading mechanism. Subsequently, the loading mechanism (such as a robotic arm) drives the positioning tool to move towards the contactor semi-finished product to accurately transfer the wire clamping screw to the contactor's connection point, completing the installation. This process greatly improves installation efficiency, but significant technical challenges remain in actual operation.

[0004] The unique structure of wire clamping screws is one of the main reasons for installation difficulties. Wire clamping screws typically consist of a clamping plate and a screw, with a certain amount of play between them. Traditional wire clamping screw positioning tools are often designed with an emphasis on positioning a single component (such as fixing only the screw or clamping plate), neglecting the relative motion characteristics between the two. This leads to the wire clamping screw easily wobbling during positioning, transfer, and installation. This wobbling not only affects the alignment accuracy between the wire clamping screw and the contactor terminals, causing installation deviations, but can also cause the wire clamping screw to fall off due to excessive wobbling, severely impacting the success rate of installation and overall efficiency.

[0005] In view of the above problems, it is necessary to develop a wire screw positioning tool that can effectively reduce the wobble of the wire screw. Utility Model Content

[0036] The positioning part 2 is integrally connected to one end of the main rod part 1. The positioning part 2 has a head positioning groove 21, a wire pressing plate positioning groove 22, and a screw positioning groove 23 sequentially from top to bottom. The bottom surface of the head positioning groove 21 is an arc surface that matches the outer contour of the head 31 of the wire pressing screw 3, and the head positioning groove 21 is used to accommodate and position the head 31; the wire pressing plate positioning groove 22 is a square groove structure that matches the shape of the wire pressing plate 32 of the wire pressing screw 3, and the wire pressing plate positioning groove 22 is used to accommodate and position the wire pressing plate 32; the bottom surface of the screw positioning groove 23 is an arc surface that matches the outer contour of the screw 33 of the wire pressing screw 3, and the screw positioning groove 23 is used to accommodate and position the screw 33.

[0037] Compared with existing technologies, the above-described wire clamping screw positioning tool has the following advantages:

[0038] 1) The structure is simple and can be manufactured using simple machining.

[0039] 2) The head positioning groove 21, the wire pressing plate positioning groove 22 and the screw positioning groove 23 can simultaneously and accurately fix the head 31, the wire pressing plate 32 and the screw 33 of the wire pressing screw 3. This layered positioning design has a good positioning effect and can effectively reduce the shaking of the wire pressing screw 3 during positioning, transfer and installation, thereby improving the installation accuracy and installation success rate of the wire pressing screw 3.

[0040] See Figure 2 As shown, Figure 2 This is a perspective view of the second embodiment of the main rod portion. The main rod portion 1 includes a mounting portion 11 and a connecting rod portion 12. The mounting portion 11 has a connecting hole 111 for connecting to the output end of the feeding mechanism. One end of the connecting rod portion 12 is integrally connected to the mounting portion 11, and the other end is integrally connected to the positioning portion 2. The connecting rod portion 12 and the mounting portion 11 extend along the same horizontal straight line. Thus, the wire clamping screw positioning tool provided in this embodiment is generally in the shape of a long strip block, which further simplifies the structure and facilitates machining.

[0041] See Figure 1 and Figure 3 As shown, Figure 3This is a perspective view of the first embodiment of the main rod portion. In one embodiment of the main rod portion 1, and in another embodiment, the main rod portion 1 includes a mounting portion 11 and a connecting rod portion 12. The mounting portion 11 extends in a horizontal direction and has a connecting hole 111 for connecting to the output end of the feeding mechanism. One end of the connecting rod portion 12 is integrally connected to the mounting portion 11, and the other end is integrally connected to the positioning portion 2.

Thus, the wire clamping screw positioning tool provided in this embodiment can extend into narrow spaces for receiving and feeding materials in narrow spaces, avoiding collisions and interference with other mechanisms during positioning, transfer, or installation.

[0042] In addition to connecting the feeding mechanism output end via the connecting hole 111 as described above, the mounting part 11 can also be connected by clamping, pressing, welding or riveting.

[0043] See Figure 4 and Figure 5 As shown, Figure 4 This is a perspective view of the wire-pressing screw positioning tool with a limited positioning surface in the embodiment. Figure 5 This is a cross-sectional view of the wire pressing screw positioning tool with a limiting surface in the embodiment. Based on any of the above embodiments, the inner wall of the wire pressing plate positioning groove 22 near the screw positioning groove 23 has a limiting surface 24. The limiting surface 24 extends obliquely upward from the bottom of the wire pressing plate positioning groove 22. In this way, the limiting surface 24 can guide the wire pressing screw 3 to move towards the bottom of the limiting groove of the wire pressing plate 32, thereby effectively reducing the risk of the wire pressing screw 3 shaking or even falling off the positioning part 2 during positioning, transfer or installation, and further improving the positioning effect.

[0044] See Figure 4 As shown, based on the above embodiment, the inner wall of the pressure plate positioning groove 22 near the screw positioning groove 23 also has two contact surfaces 25. The two contact surfaces 25 are symmetrically distributed on both sides of the limiting surface 24, and extend downwards at an angle from the middle position of the pressure plate positioning groove 22 towards both sides. The slope of the contact surface 25 is the same as the slope of the bottom surface of the pressure plate 32. The contact surfaces 25 are used to contact the bottom surfaces of both sides of the pressure plate 32. Thus, the contact surfaces 25 cooperate with the bottom surface of the pressure plate 32, improving the stability of the pressure screw 3 placed on the pressure screw positioning tool, thereby effectively reducing the risk of the pressure screw 3 shaking during positioning, transfer, or installation, and further improving the positioning effect. Furthermore, the contact surfaces 25 can guide the pressure screw 3 to smoothly disengage from the positioning part 2 after leaving the limiting surface 24.

[0045] See Figure 3 and Figure 5As shown, based on any of the above embodiments, a magnet mounting hole 26 is provided at the bottom of the screw positioning groove 23. The magnet mounting hole 26 extends to the outside of the positioning part 2 or the main rod part 1 and is used for magnet mounting. The axis of the magnet mounting hole 26 is perpendicular to the axis of the screw 33 in the screw positioning groove 23. In this way, the magnet can assist in fixing the wire clamping screw 3 through the magnet mounting hole 26, further avoiding and reducing the shaking of the wire clamping screw 3 during positioning, transfer and installation.

[0046] See Figure 4 and Figure 5 As shown, based on any of the above embodiments, the positioning part 2 also has a gradually expanding opening 27. The gradually expanding opening 27 communicates with the screw positioning groove 23 and / or the head positioning groove 21. The diameter of the gradually expanding opening 27 gradually increases from the inside of the screw positioning groove 23 to the outside of the groove. In this way, the gradually expanding opening 27 can play a guiding role so that the wire pressing screw 3 can be smoothly moved into the head positioning groove 21, the wire pressing plate positioning groove 22 and the screw positioning groove 23.
