Therefore, a new structure is designed to address the problem of poor testing efficiency in existing fixtures for pressure sensors.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

Detailed Implementation
[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] A limiting fixture for a rotary pressure sensor, such as Figure 1 As shown, the structure includes a support base 1, which provides stable support and limits the overall structure. The top surface of the support base 1 is sequentially configured around its central axis as a detection area 2, a feeding area 3, and a loading area 4. A rotating shaft 5, with its central axis coinciding with the support base 1, is rotatably connected to the support base 1. A servo motor or other power source is connected to the rotating shaft 5, allowing it to be stably driven and rotated. Several circumferentially distributed workstations 6 are fixedly connected to the top surface of the rotating shaft 5 by welding. Each workstation 6 has several workstation slots 7 arranged in an array along its length. The cross-sectional shape and dimensions of the workstation slots 7 are consistent with those of the pressure sensor, enabling pressure measurement via the workstation slots 7. The stable limiting of the force sensor allows the pressure sensor to remain in a stable position and be detected stably during detection. The work station slot 7 is equipped with a material plate 8 that slides vertically. The cross-sectional dimensions and shape of the material plate 8 are consistent with those of the work station slot 7. The top surface of the material plate 8 in the unloading area 3 is flush with the top surface of the work station seat 6. The support base 1 is fixedly connected by welding to the discharge track 9 and the push plate 10 for pushing the workpiece on the work station seat 6 into the discharge track 9. When the work station seat 6 slides relative to the push plate 10, the workpiece on the work station seat 6 will contact the push plate 10 and be pushed, and then slide along the work station seat 6 into the discharge track 9, where it will be temporarily stored.
[0021] like Figures 1-4 As shown, a symmetrically arranged limiting strip 11 with the same length direction is integrally formed on the top surface of the workstation 6. A limiting cavity 12 with openings at both ends in the length direction is formed between the two limiting strips 11. The inner bottom surface and the cavity wall of the limiting cavity 12 are polished to make the cavity wall and the inner bottom surface of the limiting cavity 12 flatter and smoother. The limiting cavity 12 is machined with a milling cutter. The depth of the limiting cavity 12 is half the thickness of the pressure sensor placed inside it. During the process of the pressure sensor sliding along the limiting cavity 12, the limiting strip 11 abuts against the pressure sensor. The limiting cavity 12 is used to stably guide and limit the sliding process of the pressure sensor, making the sliding process of the pressure sensor along the limiting cavity 12 more stable and smooth.
[0022] like Figures 1-4 As shown, a sliding rod 13 is fixedly connected to the bottom of the material plate 8 by welding. Both the sliding rod 13 and the material plate 8 are made of carbon steel. The bottom end of the sliding rod 13 is curved and gradually comes into contact with the top surfaces of the unloading area 3, the loading area 4, and the inspection area 2 as the workstation seat 6 rotates. The height of the top surfaces of the unloading area 3, the loading area 4, and the inspection area 2 decreases progressively. The connecting section between the unloading area 3 and the loading area 4 is provided with a first inclined surface 14 connecting the top surfaces of the unloading area 3 and the loading area 4. The connecting section between the loading area 4 and the inspection area 2 is provided with... A second inclined surface 15 connects the top surfaces of the loading area 4 and the detection area 2. A third inclined surface 16 connects the detection area 2 and the unloading area 3. Under the action of the first inclined surface 14, the second inclined surface 15, and the third inclined surface 16, a stable guide is achieved for the sliding process of the sliding rod 13 at its bottom side, so that the sliding rod 13 can stably slide from the unloading area 3 to the loading area 4, from the loading area 4 to the detection area 2, and from the detection area 2 to the unloading area 3 in an abutting state. When in zone 3, under the support and clamping action of the sliding rod 13, the top surface of the material plate 8 remains flush with the top surface of the unloading zone 3, causing the pressure sensor to disengage from the groove wall of the workstation trough 7, allowing the pressure sensor to be pushed out of the limiting cavity 12. When in the loading zone 4, since the top surface of the loading zone 4 is lower than the top surface of the unloading zone 3, the material plate 8 and the sliding rod 13 will slide downwards under the influence of their own gravity, exposing the workstation trough 7, thus enabling the workstation trough 7 to stably limit the placement of the pressure sensor. When in the detection zone 2, since the top surface of the detection zone 2 is lower than the top surface of the loading zone 4, the material plate 8 will slide further downwards under the influence of their own gravity, thus allowing the pressure sensor to be embedded deeper into the workstation trough 7, making the limiting function of the workstation trough 7 for the pressure sensor more stable, and enabling the pressure sensor to be stably detected.
[0023] like Figures 1-4 As shown, the width of the discharge track 9 is greater than the width of the limiting cavity 12. This setting allows the discharge track 9 to stably receive the sensor that slides out of the limiting cavity 12. The cross-section of the station groove 7 is circular, and the width of the limiting cavity 12 is greater than the diameter of the station groove 7. This setting allows the limiting cavity 12 to give way to the pressure sensor during the sliding process, reducing the possibility of the pressure sensor getting stuck during the sliding process, and making the process of the pressure sensor sliding out of the limiting cavity 12 more stable and smooth.
[0024] like Figures 1-4As shown, a support ring area 17 is provided between the detection area 2, the unloading area 3 and the loading area 4 and near the central axis of the support base 1. This support ring area 17 is used to abut against the bottom surface of several workstations 6. The support ring area 17 is used to provide stable support for the workstations 6, making the rotation of the workstations 6 more stable during the drive of the rotating shaft 5. This makes the movement of the pressure sensors placed on the workstations 6 smoother and more stable.
[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
