Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding processing positioning technology, and in particular relates to a welding processing positioning fixture for temperature sensors. Background Technology
[0002] The function of a sensor depends on the coordinated work of its components (such as the sensing element sensing signals, the electrodes transmitting electrical signals, and the outer shell protecting the internal structure). Sensor welding is a key step in sensor manufacturing. Through metallurgical bonding or fusion bonding between atoms, the dispersed components are firmly combined to form a stable mechanical structure.
[0003] Currently, existing positioning fixtures are typically suitable for sensors with a certain shape of shell, which reduces the applicability and effectiveness of the positioning fixtures. Furthermore, during the welding process, it is often necessary to manually rotate the sensor to adjust its angle, which is time-consuming, labor-intensive, and has a slow adjustment rate.
[0004] To address the aforementioned issues, this application proposes a positioning fixture for welding and processing temperature sensors. Utility Model Content
[0005] The purpose of this invention is to provide a positioning fixture for welding and processing temperature sensors, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a positioning fixture for welding and processing temperature sensors, including a base and a clamping seat disposed above the base. Multiple clamping plates are circumferentially arranged below the clamping seat. Sliding sleeves, each fixedly connected to a clamping plate, are disposed within grooves on the bottom surface of the clamping plates. A movable block is disposed above the clamping seat, and a connecting rod is circumferentially arranged between the movable block and the sliding sleeves. The movable block's lifting and lowering, via the connecting rod, causes the sliding sleeves and clamping plates to move laterally. A rotating outer shell is fixedly connected to the top of the clamping seat. The rotating outer shell passes through a lifting seat, and the lifting seat is rotatably connected. The rotation of the rotating outer shell causes the clamping seat to rotate synchronously.
[0008] Furthermore, the movable block is circumferentially fixed with a hinge seat that is hinged to the top of the connecting rod, and the top of the sliding sleeve is fixed with a hinge seat that is hinged to the bottom of the connecting rod.
[0009] Furthermore, a fixing post is coaxially fixed in the groove opened on the bottom surface of the clamping seat, and a smooth rod is circumferentially fixed between the outer wall of the fixing post and the inner wall of the clamping seat. The smooth rod passes through the sliding sleeve and is slidably connected to the sliding sleeve.
[0010] Furthermore, a screw rod threadedly connected to the moving block is rotatably installed inside the rotating housing, and a motor with a drive shaft fixedly connected to the top of the screw rod is installed on the top surface of the rotating housing.
[0011] Furthermore, the top of the clamping seat is provided with a connecting groove that communicates with the groove on the bottom surface of the clamping seat, and the connecting groove is connected by a connecting rod.
[0012] Furthermore, a driven gear is provided above the lifting seat and fixed to the outer wall of the rotating housing, and the driven gear is meshed with the driving gear. An outer protective shell is fixed at the top of the lifting seat, and the driven gear and the second motor are both located inside the outer protective shell. The top plate of the outer protective shell is fixed with a second motor whose output end is fixed to the driving gear.
[0013] Furthermore, a fixed frame is fixedly provided at the top of the base, and an electric push rod with its output end fixedly connected to the top surface of the lifting seat is installed at the top of the fixed frame. A vertical telescopic rod is fixed between the top plate of the fixed frame and the lifting seat.
[0014] Furthermore, a rubber pad is fixed to the side of the clamp that contacts the sensor.
[0015] This utility model has the following beneficial effects:
[0016] This invention uses multiple clamping plates to clamp and fix the sensor by moving simultaneously. The clamping plates can clamp and fix sensors of different sizes. There are multiple contact points between the multiple clamping plates and the sensor, so it is suitable for clamping sensors of different shapes.
[0017] This invention rotates the outer shell to drive the clamping base to rotate, thereby causing the sensor held by the clamping plate to rotate and adjusting the circumferential angle of the sensor, making it convenient for users to perform sensor welding operations.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] Please see Figure 1 - Figure 4 As shown, this utility model is a positioning fixture for welding and processing of temperature sensors, including a base 1 and a clamping seat 2, which is set above the base 1. Multiple clamping plates 5 are arranged circumferentially below the clamping seat 2. Sliding sleeves 4 are respectively fixedly connected to the clamping plates 5 in the grooves opened on the bottom surface of the clamping plates 5. A moving block 7 is provided above the clamping seat 2. A connecting rod 6 is arranged circumferentially between the moving block 7 and the sliding sleeves 4. The moving block 7 moves up and down, and the sliding sleeves 4 and clamping plates 5 move laterally through the connecting rod 6. The rotating outer shell 10 is fixedly connected to the top of the clamping seat 2. The rotating outer shell 10 passes through the lifting seat 11 and is rotatably connected to the lifting seat 11. The rotation of the rotating outer shell 10 drives the clamping seat 2 to rotate synchronously.
[0029] This embodiment provides a positioning fixture for welding temperature sensors. The movable block 7 can move vertically, and through the connecting rod 6, it pushes the sliding sleeve 4 and the clamping plate 5 to move synchronously closer to or away from the central axis of the clamping seat 2, placing the sensor between the clamping plates 5. The clamping plates 5 clamp and fix the sensor close to the central axis of the clamping seat 2. The circumferentially arranged clamping plates 5 have multiple contact points with the sensor, realizing the fixation of sensors of different shapes. During welding, rotating the rotating housing 10 can drive the clamping seat 2 to move, further driving the clamping plates 5 and the sensor clamped and fixed to rotate, realizing the circumferential angle adjustment of the sensor.
[0030] The movable block 7 is circumferentially fixed with a hinge seat that is hinged to the top of the connecting rod 6, and the top of the sliding sleeve 4 is fixed with a hinge seat that is hinged to the bottom of the connecting rod 6. Through the hinge transmission of the connecting rod 6, the vertical movement of the movable block 7 is converted into the horizontal movement of the sliding sleeve 4 and the clamping plate 5, ensuring that the circumferentially set clamping plate 5 can move synchronously and improving the clamping stability.
[0031] In this device, a fixing post 201 is coaxially fixed in the groove opened on the bottom surface of the clamping seat 2. A smooth rod 3 is circumferentially fixed between the outer wall of the fixing post 201 and the inner wall of the clamping seat 2. The smooth rod 3 passes through the sliding sleeve 4 and is slidably connected to the sliding sleeve 4. The smooth rod 3 plays a guiding role for the movement of the sliding sleeve 4, ensuring that the clamping plate 5 moves smoothly along a straight line and preventing the clamping plate 5 from deviating.
[0032] The rotating housing 10 contains a screw 8 that is threadedly connected to the moving block 7. The top surface of the rotating housing 10 is equipped with a drive shaft and a motor 9 that is fixedly connected to the top of the screw 8. The two ends of the screw 8 are rotatably connected to the rotating housing 10 and the clamping seat 2, respectively. The motor 9 drives the screw 8 to rotate, which in turn drives the moving block 7 to rise and fall, thereby realizing the automatic control of the clamping plate 5.
[0033] The clamping seat 2 has a connecting groove 202 on its top circumferential direction that communicates with the groove on the bottom surface of the clamping seat 2. The connecting groove 202 is connected by the connecting rod 6. The connecting groove 202 is designed to prevent the connecting rod 6 from colliding with the clamping seat 2 and to avoid structural interference.
[0034] The lifting seat 11 is provided with a driven gear 12 fixedly connected to the outer wall of the rotating housing 10, and the driven gear 12 is meshed with the driving gear 13. The top of the lifting seat 11 is fixedly provided with an outer protective shell 15. The driven gear 12 and the second motor 14 are both located inside the outer protective shell 15. The top plate of the outer protective shell 15 is fixedly provided with a second motor 14 whose output end is fixedly connected to the driving gear 13. The second motor 14 drives the driving gear 13 to rotate, and further drives the rotating housing 10 to rotate through the second motor 14, thereby driving the clamping seat 2 to rotate synchronously.
[0035] The base 1 has a fixed frame 101 at its top, and an electric push rod 16 with its output end fixed to the top surface of the lifting seat 11 is installed at the top of the fixed frame 101. A vertical telescopic rod 17 is fixed between the top plate of the fixed frame 101 and the lifting seat 11. The electric push rod 16 drives the lifting seat 11 to move vertically, adjusting the horizontal height of the clamping seat 2 to meet the needs of welding stations at different heights. The telescopic rod 17 guides the movement of the lifting seat 11, ensuring that the lifting seat 11 moves vertically smoothly under the drive of the output end of the electric push rod 16.
[0036] The side of the clamping plate 5 that contacts the sensor is fixed with a rubber pad 501. The rubber pad can increase friction and prevent the sensor from sliding, and at the same time, it can also prevent the clamping plate 5 from damaging the sensor surface.
[0037] It is understood that this utility model can clamp and fix sensors of different shapes and sizes, and then adjust the circumferential angle of the sensors.
[0038] A specific application of the operation process of this embodiment is as follows: the sensor is placed between the clamping plates 5 from below the clamping seat 2, and then the drive motor 9 drives the screw 8 to rotate, which further drives the moving block 7 to move vertically, thereby causing the sliding sleeve 4 and the clamping plate 5 to move horizontally synchronously through the connecting rod 6 to clamp and fix the sensor.
[0039] The electric push rod 16 drives the lifting seat 11 to move vertically, and the rotating housing 10 drives the clamping seat 2 to move vertically, thereby adjusting the height of the sensor.
[0040] The motor 14 drives the drive gear 13 to rotate, which in turn drives the driven gear 12 to rotate the rotating housing 10, thereby rotating the clamping seat 2 and adjusting the circumferential angle of the sensor held by the clamping plate 5.
