Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor processing technology, specifically to a sensor inner core side needle bending device. Background Technology
[0002] With the continuous development of smart hardware, automated equipment, and sensor technology, the performance and accuracy of sensors have had a profound impact on all aspects of modern industrial production and daily life. As the core of sensor functionality, the precision and quality of its assembly and manufacturing process directly affect the sensor's operational stability and reliability. Among the complex connecting components inside the sensor, the bending assembly of the side pins is a critical process.
[0003] Currently, many sensor designs employ an inner core side pin connection method, which requires precise bending of the side pins during manufacturing. However, traditional pin bending devices often face the following problems during processing:
[0004] Traditional needle bending equipment suffers from poor bending results due to a lack of precise control and a stable operating platform. This error can accumulate, especially during mass production, affecting product quality and consistency. Deviations in bending angle and position can also cause sensors to malfunction or become unstable.
[0005] Because the bending device may have operational errors during operation, the accuracy of the bending needle cannot be guaranteed. This is especially true when machining sensors with complex structures, as such errors can affect subsequent assembly and testing. Insufficiently accurate bending needles can also lead to weak internal connections within the sensor, thus affecting the sensor's performance and long-term stability.
[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a sensor inner core side needle bending device. Utility Model Content

[0013] The lifting seat is slidably connected to the lifting seat guide rod, and the driving hydraulic cylinder drives the lifting seat to move vertically along the lifting seat guide rod, so that the extrusion surface of the bending needle seat and the bending needle slope surface of the bending needle lower seat work together to bend the side needle placed on the side needle fixing frame.
[0014] As a preferred technical solution, the bend surface is an inclined surface, and its inclination angle matches the inclination angle of the extrusion surface, forming a progressive bending structure.

Detailed Implementation
[0025] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a sensor inner core side needle bending device: it includes a frame 1, which provides a stable support structure for the entire device. A driving hydraulic cylinder 2 is fixedly installed on the frame 1, and the driving rod 21 of the hydraulic cylinder 2 is connected to a lifting seat 22. The lifting seat 22 is slidably connected to a lifting seat guide rod 24, which consists of two parallel rigid rods symmetrically distributed on both sides of the driving hydraulic cylinder 2 to ensure the vertical movement accuracy of the lifting seat 22.
[0027] The bending needle holder 23 is located below the lifting seat 22, and the lower surface of the bending needle holder 23 is provided with a pressing surface 231 for pressing the side needle 41. The bending needle holder 23 and the lifting seat 22 are connected by detachable bolts for easy maintenance and replacement. The pressing surface 231 is made of wear-resistant alloy to improve its durability and reduce wear.
[0028] The support base 3 is fixed to the frame 1, and the support base 3 is provided with a side needle seat 31 and a lower bending needle seat 32. The side needle seat 31 is provided with a fixing bracket slot 311 for fixing the side needle fixing bracket 42. The fixing bracket slot 311 is a rectangular groove, the size of which is adapted to the bottom shape of the side needle fixing bracket 42, and is used to fix the horizontal position of the side needle fixing bracket 42. The upper surface of the lower bending needle seat 32 is provided with a bending needle slope 321 that mates with the extrusion surface 231. The bending needle slope 321 is an inclined surface, and its inclination angle matches the inclination angle of the extrusion surface 231, forming a progressive bending structure.
[0029] The stroke control module of the hydraulic cylinder 2 is equipped with a displacement sensor to monitor the displacement of the lifting seat 22 in real time, so as to ensure the bending accuracy of the side needle 41.
[0030] In actual operation, the hydraulic cylinder 2 drives the lifting seat 22 to move vertically along the lifting seat guide rod 24, and the lifting seat 22 drives the bending needle seat 23 to move up and down. When the lifting seat 22 descends, the pressing surface 231 of the bending needle seat 23 and the bending needle slope surface 321 of the lower bending needle seat 32 work together to bend the side needle 41 placed on the side needle fixing frame 42. By precisely controlling the descending position and force of the lifting seat 22, precise control of the bending angle and position of the side needle 41 can be achieved, thereby improving the processing quality of the side needles in the sensor core.
[0031] The sensor inner core side pin bending device of this utility model effectively solves the problems of insufficient precision and poor stability in the bending process of traditional pin bending devices through precise mechanical structure design and hydraulic control, thereby improving the processing quality and production efficiency of sensor inner core side pins.
