Description

Technical Field

[0001] This utility model relates to the field of sensor processing technology, and in particular to a movable fixture for processing temperature sensors. Background Technology

[0002] Temperature sensors are sensing devices used to detect and measure temperature changes and convert temperature signals into electrical signals for output. They are widely used in industrial control, environmental monitoring, home appliances, automotive electronics, and many other fields. With the continuous improvement of modern industrial automation, higher requirements are placed on the processing accuracy and assembly stability of temperature sensors. In the production and processing of temperature sensors, fixtures, as key process equipment for workpiece positioning and clamping, directly affect processing efficiency, product qualification rate, and operational safety due to their structural rationality and ease of operation.

[0003] Utility model patent CN 214121456 U discloses a movable fixture for processing temperature sensors, including a lifting mechanism. A lifting plate is fixedly provided on one side of the lifting mechanism, and a fixing mechanism is provided on one side of the lifting plate. The fixing mechanism includes a fixing rod. A disassembly mechanism is provided between one end of the fixing rod and the lifting plate. A circular retainer is provided at the other end of the fixing rod. A first support member is provided inside the circular retainer. The circular retainer is fixedly connected to the fixing rod through the first support member. Fixing holes are opened inside the circular retainer. The fixing holes are evenly opened inside the circular retainer. Movable cavities are opened on both sides of the inner wall of the fixing holes. Springs are provided inside the movable cavities. One end of the spring is fixed to the bottom surface inside the movable cavity. A first fixing member is provided at the other end of the spring. The first fixing member is fixedly connected to the spring. The inner diameter of the movable cavity is larger than the outer diameter of the first fixing member.

[0004] Although the aforementioned patent uses springs to clamp and fix the temperature sensor, it still exposes technical problems in actual use: Specifically, the clamp relies on only two springs to provide clamping force, which can easily lead to problems such as clamping instability and positioning deviation during the clamping process. This can cause the sensor to shift slightly during processing, affecting the processing accuracy. The ends of the springs act directly on the outer wall of the sensor, which can easily cause scratches or indentations on the sensor shell during clamping, affecting the appearance quality and even damaging the internal components.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a movable fixture for temperature sensor processing. This new fixture should significantly improve the stability and versatility of the clamping process, avoid damage to the sensor's outer wall during clamping, and possess excellent adaptive adjustment capabilities to meet the rapid clamping needs of products of different sizes and specifications. It should better adapt to the development trend of intelligent and efficient processing, providing strong support for the technological upgrading of the temperature sensor manufacturing industry. Utility Model Content

[0006] The purpose of this invention is to provide a movable fixture for processing temperature sensors, which solves the problem in the prior art that relies solely on two springs to provide clamping force, which easily leads to problems such as unstable clamping and positioning deviation during the clamping process, causing the sensor to shift slightly during processing and affecting the processing accuracy.

[0007] To achieve the above objectives, this utility model provides a movable fixture for processing temperature sensors, including a base and a test pool. A placement plate is provided on the top of the test pool, and a vertical lifting module connected to the top of the base is provided on one side of the test pool.

[0008] A mounting plate is provided on one side of the vertical lifting module, and the mounting plate is connected to the lifting end of the vertical lifting module. A connecting bracket connected to the mounting plate is provided on one side of the placement plate.

A movable column with one end sliding through the placement plate is provided on one side between the two fixed columns. A movable plate is provided on the side of the placement plate away from the connecting bracket. One end of each movable column is connected to the side wall of the movable plate. The movable plate is connected to the side wall of the placement plate through a horizontal adjustment structure.

[0010] The bottom of the placement plate is provided with a flip plate, and both ends of the flip plate are rotatably connected to side plates connected to the bottom of the placement plate. One end of the placement plate is provided with a rotating component for driving the flip plate to rotate.

[0011] The connecting bracket is made of metal, and one end of the connecting bracket is fixedly connected to the mounting plate with bolts, while the other end is fixedly connected to the side wall of the placement plate with bolts.

[0012] Both the fixed column and the movable column are fixedly connected to rubber pads at their ends, and the ends of the rubber pads are provided with anti-slip grooves.

[0013] The horizontal adjustment structure includes an adjustment screw, one end of which is threaded through the movable plate and rotatably connected to the side wall of the placement plate.

[0014] The rotating structure includes a top plate, a toothed plate, and a gear disk. The top plate is connected to one end of the placement plate. The toothed plate is located at the bottom of the top plate. The gear disk is connected to the toothed plate through a meshing tooth. A rotating shaft is connected to one side of the gear disk.

[0015] The vertical lifting structure includes a push cylinder installed on the top of the top plate, and the output end of the push cylinder is connected to the top of the toothed plate.

[0016] This utility model discloses a movable fixture for processing temperature sensors. Through a clamping structure with a fixed column and a movable column, combined with the linkage control of a moving plate and a horizontal adjustment structure, it achieves synchronous and stable clamping of multiple temperature sensors, improving the rigidity and repeatability of the clamping process and avoiding sensor displacement or detachment caused by insecure clamping. Simultaneously, the use of a columnar structure at the clamping contact points instead of the traditional direct spring contact method reduces the risk of damage to the outer shell surface, protecting the sensor's appearance quality and the integrity of its internal components. The coordinated design of the flip plate and rotating assembly provides reliable bottom support for the sensors before testing, ensuring that all sensor ends are on the same plane, improving the consistency and accuracy of test data.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example

[0025] Please see Figure 1-5 As shown, a movable fixture for processing temperature sensors in this embodiment includes a base 1 and a test pool 2. A placement plate 4 is provided on the top of the test pool 2, and a vertical lifting module 3 connected to the top of the base 1 is provided on one side of the test pool 2.

[0026] A mounting plate is provided on one side of the vertical lifting module 3. The mounting plate is connected to the lifting end of the vertical lifting module 3. A connecting bracket 6 connected to the mounting plate is provided on one side of the placement plate 4.

[0027] The top of the placement plate 4 is provided with several placement slots 16. Each placement slot 16 has two fixed columns 9 symmetrically arranged inside. Between the two fixed columns 9, a movable column 8 with one end sliding through the placement plate 4 is provided on one side. A movable plate 7 is provided on the side of the placement plate 4 away from the connecting bracket 6. One end of each movable column 8 is connected to the side wall of the movable plate 7. The movable plate 7 is connected to the side wall of the placement plate 4 through a horizontal adjustment structure.

[0028] A flip plate 5 is provided at the bottom of the placement plate 4. Both ends of the flip plate 5 are rotatably connected to side plates 11 that are connected to the bottom of the placement plate 4. A rotating component for driving the flip plate 5 to rotate is provided at one end of the placement plate 4.

[0029] In the workflow, the operator first places several temperature sensors to be tested into the multiple placement slots 16 opened on the top of the placement plate 4. At this time, the rotating component drives the flip plate 5 from a vertical state to a position parallel to the placement plate 4, serving as an effective support surface for the bottom of the sensors and ensuring that the ends of each sensor are at the same height. Subsequently, the horizontal adjustment structure is activated to move the moving plate 7 towards the placement plate 4, thereby pushing the connected movable column 8 to move synchronously. The movable column 8 and the fixed column 9 work together on both sides of the sensors to achieve stable clamping of multiple sensors. After clamping is completed, the rotating component flips the flip plate 5 back to a vertical state to avoid interfering with subsequent testing operations. Finally, the vertical lifting module 3 is used to drive the mounting plate and connecting bracket 6 installed on its lifting end to descend, thereby moving the entire placement plate 4 and the multiple temperature sensors on it synchronously downward and completely immersed in the test pool 2 for temperature testing. Example

[0030] Please see Figure 1-5As shown in the figure, a movable fixture for processing temperature sensors in this embodiment has a connecting bracket 6 made of metal. One end of the connecting bracket 6 is bolted to the mounting plate, and the other end is bolted to the side wall of the placement plate 4. Specifically, by setting the connecting bracket 6 to the mounting plate and the placement plate 4 to be bolted together, the metal connecting bracket 6 can provide higher structural strength and stability during the lifting or moving of the fixture as a whole. At the same time, it is easy to disassemble and replace, thereby achieving the effect of enhancing the overall structural rigidity, improving clamping stability and maintenance convenience.

[0031] The horizontal adjustment structure includes an adjustment screw 10. One end of the adjustment screw 10 is threaded through the side wall of the moving plate 7 and the placement plate 4 for rotational connection. Specifically, through the cooperation between the adjustment screw 10, the moving plate 7, and the placement plate 4, when making horizontal clamping adjustments, rotating the adjustment screw 10 can drive the moving plate 7 to move smoothly along the side wall of the placement plate 4, thereby achieving precise control of the position of the movable column 8 and achieving the technical effect of improving clamping accuracy and adapting to the rapid clamping of sensors of different sizes. Example

[0032] Please see Figure 1-5 As shown in the figure, in this embodiment, a movable clamp for processing a temperature sensor has rubber pads fixedly connected to the ends of both the fixed column 8 and the movable column 9. The ends of the rubber pads are provided with anti-slip grooves. Specifically, by combining the rubber pads and anti-slip grooves at the ends of the fixed column 9 and the movable column 8, the rubber pads adhere to the outer wall of the sensor when clamping the temperature sensor, and the anti-slip grooves increase the friction to prevent the sensor from sliding or shifting. At the same time, direct metal contact is avoided to prevent damage to the outer shell, thus achieving the effect of protecting the appearance quality of the sensor and improving the clamping reliability.

[0033] The rotating structure includes a top plate 13, a toothed plate 14, and a gear disk 15. The top plate 13 is connected to one end of the placement plate 4. The toothed plate 14 is located at the bottom of the top plate 13. The gear disk 15 is connected to the toothed plate 14 through a meshing tooth. A rotating shaft is connected to one side of the gear disk 15. One end of the rotating shaft rotates through the adjacent side plate 11 and connects to the side wall of the flipping plate 5. The toothed plate 14 is connected to the bottom of the top plate 13 through a vertical lifting structure. Specifically, through the cooperation between the push cylinder 12 and the toothed plate 14, during the flipping process of the flipping plate 5, the push cylinder 12 is activated, and its output end pushes the toothed plate 14 downward, driving the gear disk 15 to rotate, thereby driving the flipping plate 5 to complete the angle change. This realizes automated flipping control and achieves the technical effect of improving operating efficiency and reducing manual intervention.

[0034] The vertical lifting structure includes a push cylinder 12 installed on the top of the top plate 13. The output end of the push cylinder 12 is connected to the top of the gear plate 14. Specifically, through the cooperation between the push cylinder 12 and the gear plate 14, during the flipping process of the flipping plate 5, the push cylinder 12 is activated, and its output end pushes the gear plate 14 to move downward, driving the gear disk 15 to rotate, thereby driving the flipping plate 5 to complete the angle change, realizing automated flipping control, and achieving the technical effect of improving operating efficiency and reducing manual intervention.

[0035] This utility model discloses a movable fixture for processing temperature sensors. Its complete structure includes key components such as a base 1, a test pool 2, a vertical lifting module 3, a placement plate 4, a flip plate 5, a connecting bracket 6, a moving plate 7, a movable column 8, a fixed column 9, an adjusting screw 10, a side plate 11, a pushing cylinder 12, a top plate 13, a toothed plate 14, a gear disk 15, and a placement groove 16. In the specific workflow, the operator first places multiple temperature sensors to be tested into several placement slots 16 located on the top of the placement plate 4. At this time, the rotating assembly drives the flip plate 5 from a vertical position to a position parallel to the placement plate 4, serving as an effective support surface for the bottom of the sensors and ensuring that the ends of each sensor are at the same height. Subsequently, the adjusting screw 10 in the horizontal adjustment structure is activated, causing the moving plate 7 to move along the side wall of the placement plate 4, thereby pushing the multiple movable columns 8 connected to it to move synchronously. The movable columns 8 and the fixed columns 9 work together on both sides of the sensors to achieve stable clamping of multiple sensors. After clamping is completed, the rotating assembly flips the flip plate 5 back to a vertical position to avoid interfering with subsequent testing operations. Finally, the vertical lifting module 3 drives the mounting plate and connecting bracket 6 installed at its lifting end to descend, thereby causing the entire placement plate 4 and the multiple temperature sensors on it to move down synchronously and be completely immersed in the test pool 2 for temperature testing. Furthermore, the connecting bracket 6 is made of metal and is fixedly connected to the mounting plate and the placement plate 4 by bolts, providing higher structural strength and stability during the overall lifting or movement of the clamp, while facilitating disassembly and replacement, enhancing the overall structural rigidity, improving clamping stability, and simplifying maintenance. Both the fixed column 9 and the movable column 8 have rubber pads at their ends, with anti-slip grooves on the surface. During clamping, these pads adhere to the outer wall of the sensor, increasing friction and preventing sensor slippage. They also avoid direct metal-to-metal contact that could damage the outer shell, effectively protecting the sensor's appearance and improving clamping reliability. One end of the adjusting screw 10 is threaded through the movable plate 7 and rotatably connected to the side wall of the placement plate 4. During horizontal clamping adjustments, rotating the adjusting screw 10 allows the movable plate 7 to move smoothly, achieving precise control of the movable column 8's position. This adapts to the rapid clamping needs of sensors of different sizes and improves clamping accuracy. The rotating assembly consists of a top plate 13, a toothed plate 14, and a gear disk 15. A push cylinder 12 is mounted on the top plate 13, with its output end connected to the toothed plate 14. During the flipping process of the flipping plate 5, the push cylinder 12 is activated, and its output end pushes the toothed plate 14 downwards, causing the gear disk 15 to rotate. This drives the flipping plate 5 to complete the angle change, achieving automated flipping control, improving operational efficiency, and reducing manual intervention. The two ends of the flipping plate 5 are rotatably connected to the placement plate 4 via side plates 11, providing uniform height support for the sensors before testing, ensuring that all sensor ends are on the same plane, and improving the consistency and accuracy of test data.

[0036] In summary, this clamp effectively solves the technical problems of unstable clamping and easy damage to sensor housings caused by relying solely on spring clamping in existing technologies. By setting up a clamping structure with the fixed column 9 and the movable column 8 cooperating, and combining the linkage control of the moving plate 7 and the adjusting screw 10, synchronous and stable clamping of multiple temperature sensors is achieved, improving the rigidity and repeatability of the clamping process. The application of the rubber pad structure reduces the risk of damage to the surface of the housing, protecting the appearance quality of the sensor and the integrity of internal components. The design of the flip plate 5 and the gear transmission structure provides reliable bottom support for the sensor before testing, improving the consistency of test data. The automated flipping control of the driving cylinder 12 and the toothed plate 14 improves operating efficiency and reduces manual intervention.
