Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture technology, and in particular to a Hall sensor forming fixture. Background Technology
[0002] In the manufacturing process of Hall sensors, pin bending is an indispensable and crucial step. Precise pin bending not only affects the sensor's electrical connection performance but also directly impacts its compatibility with external circuits and the stability of the overall assembly. However, in actual production, due to the lack of effective fixing measures, the position of the Hall sensor pins cannot be reliably fixed during bending, causing numerous production challenges. Existing Hall sensors use a pressure block to directly press and bend the pins. Because the distance between the Hall sensor pins varies, direct compression by the pressure block can cause pin displacement, resulting in bending angle deviations or inaccurate bending positions, and even damage to the sensor body, affecting product quality and performance. Therefore, this invention proposes a Hall sensor forming fixture. Utility Model Content

[0028] Embodiment
[0029] As Figures 1 to 4 Shown in the figure, a forming fixture for a Hall sensor proposed by the present utility model includes: a base 1, a fixing block 2 is fixedly arranged on the upper surface of the base 1 through bolts, a guiding strip 3 is fixedly arranged on one side of the fixing block 2, and the guiding strip 3 is arranged in a "convex" shape structure.
[0030] Furthermore, multiple sets of sleeve blocks 4 are slidably arranged on the guiding strip 3, a limiting block 5 is fixedly arranged on one side of the sleeve block 4, a connecting block 6 is fixedly arranged on one side of the sleeve block 4, a guiding block 7 is fixedly arranged on the upper surface of the connecting block 6, and a stop block 21 is fixedly arranged at the upper end of the guiding block 7, which can drive the limiting block 5 to displace through the connecting block 6 and the guiding block 7, so as to facilitate the adjustment of the position of the limiting block 5.
[0031] Secondly, a set of slide rails 8 is fixedly arranged on the upper surface of the base 1, and the slide rails 8 are arranged in parallel. A sliding block 9 for clamping the pins of the Hall sensor is slidably arranged on the slide rails 8, which can make the sliding block 9 horizontally move according to the direction of the slide rails 8. A guiding groove 22 is formed on the bottom surface of the sliding block 9, and the guiding groove 22 is movably sleeved with the slide rails 8, making the sliding connection between the slide rails 8 and the sliding block 9 more stable. A pressing block 10 is fixedly arranged on one side of the sliding block 9, and the sliding block 9 can drive the pressing block 10 to move stably. An air cylinder 11 is fixedly installed on the upper surface of the base 1, and the output end of the air cylinder 11 is fixedly connected to the sliding block 9, and the air cylinder 11 can make the sliding block 9 slide stably on the slide rails 8.
[0032] As Figures 1 to 3 Shown in the figure, an adjusting component 12 for adjusting the position of the limiting block 5 is arranged on one side of the fixing block 2. The adjusting component 12 includes an adjusting bolt 121 rotatably arranged on one side of the fixing block 2, and a socket plate 122 is threadedly sleeved on the outer wall of the adjusting bolt 121. By rotating the adjusting bolt 121, the position of the socket plate 122 can be adjusted. A plurality of fixing plates 123 are fixedly arranged on one side of the socket plate 122, and a plurality of guiding grooves 124 are respectively formed on the fixing plates 123. The guiding grooves 124 are movably sleeved with the guiding blocks 7, and the guiding grooves 124 are arranged obliquely, which can guide the guiding blocks 7 through the guiding grooves 124, so as to quickly adjust the distance between the guiding blocks 7.
[0033] As Figure 1 , Figure 2 and Figure 4 As shown, a guide rod 13 is movably connected through the sliding block 9. One end of the guide rod 13 is fixedly connected to a pressure plate 14, which can limit the Hall sensor and prevent displacement during bending. The other end of the guide rod 13 is fixedly connected to a limit plate 15, which can prevent the guide rod 13 from detaching from the sliding block 9. A spring 16 is sleeved on the outer wall of the guide rod 13. One end of the spring 16 is fixedly connected to the sliding block 9, and the other end of the spring 16 is fixedly connected to the pressure plate 14, which can provide buffer for the pressure plate 14 and prevent excessive pressure on the Hall sensor from damaging it.
[0034] Furthermore, the limiting block 5 has a through groove 17, and the inner wall of the through groove 17 has a sliding groove 18. A slider 19 is slidably arranged in the sliding groove 18, which enables the slider 19 to slide stably according to the direction of the sliding groove 18. A limiting frame 20 is fixedly arranged between the sliders 19, which can limit the pins of the Hall sensor and prevent displacement during bending.
[0035] In this embodiment, the distance between the limiting frames 20 is adjusted according to the distance between the Hall sensor pins. The adjusting bolt 121 is manually rotated, and the adjusting bolt 121 is threaded onto the socket plate 122, thereby causing the socket plate 122 to move horizontally. The socket plate 122 generates a pushing force on the guide block 7 through the guide groove 124 on the fixing plate 123. The guide block 7 drives the sleeve block 4 to move horizontally on the guide strip 3 through the connecting block 6. The sleeve block 4 drives the limiting frames 20 on the limiting block 5 to move horizontally. Since the guide groove 124 is inclined, the limiting frames 20 move horizontally relative to or opposite to each other until the distance between the limiting frames 20 is sufficient for the Hall sensor pins to be inserted.
[0036] After adjustment, insert the Hall sensor pins into the limiting frame 20, then activate cylinder 11. The output of cylinder 11 pushes the sliding block 9 to slide horizontally on the slide rail 8. The sliding block 9, through guide rod 13, drives pressure plate 14, limiting plate 15, and spring 16 to move horizontally. This causes pressure plate 14 to push the Hall sensor horizontally through the spring force of spring 16. The Hall sensor drives the pins to move horizontally, and the pins drive the limiting frame 20 and the slider 19 on the outer wall of the limiting frame 20 to slide horizontally within the slide groove 18. This stably clamps and limits the Hall sensor.
[0037] Simultaneously, the sliding block 9 drives the pressure block 10 to move horizontally, causing the pressure block 10 to exert pressure on the pins of the Hall sensor, thereby positioning and bending the pins of the Hall sensor to ensure bending efficiency. After bending is completed, the starting cylinder 11 pulls the sliding block 9 to move and remove the bent Hall sensor.
[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
