[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1-6 , a welding device for sensor production, including a base 1 and an L-shaped plate 2 fixedly installed at the rear side of the top of the base 1. A hydraulic cylinder A3 is fixedly installed at the middle part of the top of the L-shaped plate 2, and the power end of the hydraulic cylinder A3 slides through and extends to the outside of the L-shaped plate 2. The power end of the hydraulic cylinder A3 is fixedly installed with a pushing plate 4. An opening is provided above the rear side of the L-shaped plate 2, and the rear side of the pushing plate 4 extends to the outside of the L-shaped plate 2 through the opening. A welding torch 5 is fixedly installed at the bottom of the pushing plate 4. A moving component 6 is installed at the rear side of the bottom of the pushing plate 4, and sliding blocks 7 are respectively slidably installed at both sides of the front side of the top of the base 1. The tops of the sliding blocks 7 are fixedly installed with a housing 8 together. A clamping component 9 is installed in the inner cavity of the housing 8. Through the setting of the moving component 6, the position of the housing 8 can be adjusted, which is convenient for the staff to take and place the sensor, and the setting of the clamping component 9 can clamp and fix the four sides of the sensor.

[0025] The moving component 6 includes a fixed rod 61 fixedly installed at the rear side of the bottom of the pushing plate 4 and a rack plate 62 fixedly installed at the lower end of the fixed rod 61. The output end of the rack plate 62 is engaged with a movable gear 63, and a threaded rod 64 is fixedly installed through the middle part of the movable gear 63. The front end of the threaded rod 64 movably passes through and extends to the outside of the L-shaped plate 2. A threaded sleeve 65 is threadedly installed on the output shaft of the threaded rod 64, and the top of the threaded sleeve 65 is fixedly installed on the housing 8, so that the position of the housing 8 can be adjusted.

[0026] A limiting plate 641 is movably installed at the front end of the threaded rod 64, and the bottom of the limiting plate 641 is fixedly installed on the base 1, which plays a role in limiting the threaded rod 64.

[0027] In this embodiment: when in use, the sensor can be placed on the outer shell 8. After placement, it can be fixed. After fixation, the hydraulic cylinder A3 can be operated. When the hydraulic cylinder A3 operates, it will drive the push plate 4 to move downward. When the push plate 4 moves downward, it will drive the welding torch 5 to move downward. At the same time, when the push plate 4 moves downward, it will also drive the rack plate 62 to move downward through the fixed rod 61. When the rack plate 62 moves downward, it will drive the movable gear 63 to rotate. When the movable gear 63 rotates, it will drive the threaded rod 64 to rotate. When the threaded rod 64 rotates, it will drive the threaded sleeve 65 to move backward. When the threaded sleeve 65 moves backward, it will drive the outer shell 8 to move backward. When the outer shell 8 moves backward, it will drive the sensor to move below the welding torch 5. When the push plate 4 continues to move downward, the rack plate 62 will be separated from the movable gear 63, so that the outer shell 8 will not continue to move, and the downward moving welding torch 5 will weld the sensor. After welding is completed, reverse operation can drive the welding torch 5 to move upward. After the welding torch 5 moves upward a certain distance, the rack plate 62 will engage with the movable gear 63. At this time, the threaded rod 64 can be driven to rotate in the reverse direction, so as to drive the outer shell 8 to move forward and return to its original position, which is convenient for the staff to take out the welded sensor.

[0028] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1-3 、 Figure 5 and Figure 7 The clamping assembly 9 includes a hydraulic cylinder B91 fixedly installed in the middle of the inner cavity bottom wall of the outer shell 8 and a circular plate 92 fixedly installed at the power end of the hydraulic cylinder B91. Trapezoidal blocks 93 are respectively fixedly installed at the four corners of the top of the circular plate 92, and inverted trapezoidal blocks 94 are respectively attached to the tops of the trapezoidal blocks 93. Connecting plates 95 are respectively fixedly installed above the outer sides of the inverted trapezoidal blocks 94, and sliding rods 96 are respectively fixedly installed at the tops of the connecting plates 95. The upper ends of the sliding rods 96 are respectively fixedly installed with clamping plates 97, and the clamping plates 97 are respectively located outside the outer shell 8. The sensor is clamped and fixed by driving the four-sided clamping plates 97 to move inward synchronously.

[0029] Sliding openings 81 are respectively opened at the four corners of the top of the outer shell 8, and the upper ends of the sliding rods 96 respectively slide through the sliding openings 81 and extend to the outside of the outer shell 8. The sliding openings 81 are provided for the movement of the sliding rods 96.

[0030] Vertical plates 941 are respectively arranged on the outer sides of the inverted trapezoidal blocks 94, and the bottoms of the vertical plates 941 are respectively fixedly installed on the bottom wall of the inner cavity of the housing 8. The inverted trapezoidal blocks 94 and the vertical plates 941 are elastically connected through telescopic springs 942 respectively. The arrangement of the telescopic springs 942 facilitates the movement and restoration of the inverted trapezoidal blocks 94.

[0031] In this embodiment: The operation of the hydraulic cylinder B91 will drive the circular plate 92 to move downward. When the circular plate 92 moves downward, it will drive the regular trapezoidal block 93 to move downward. When the regular trapezoidal block 93 moves downward, it will gradually lose the extrusion on the inverted trapezoidal block 94, and the inverted trapezoidal block 94 will move inward under the action of the resilience of the telescopic spring 942, so that it is always in a fitting state with the regular trapezoidal block 93. At the same time, it will also drive the clamping plate 97 to move relatively through the sliding rod 96. When the clamping plate 97 moves relatively, it will clamp and fix the sensor. After the fixing is completed, the operation of the hydraulic cylinder B91 can be stopped.

[0032] Working principle: When in use, the sensor can be placed on the housing 8. After the placement is completed, it can be fixed. The operation of the hydraulic cylinder B91 will drive the circular plate 92 to move downward. When the circular plate 92 moves downward, it will drive the regular trapezoidal block 93 to move downward. When the regular trapezoidal block 93 moves downward, it will gradually lose the extrusion on the inverted trapezoidal block 94, and the inverted trapezoidal block 94 will move inward under the action of the resilience of the telescopic spring 942, so that it is always in a fitting state with the regular trapezoidal block 93. At the same time, it will also drive the clamping plate 97 to move relatively through the sliding rod 96. When the clamping plate 97 moves relatively, it will clamp and fix the sensor. After the fixing is completed, the operation of the hydraulic cylinder B91 can be stopped. After the fixing is completed, the hydraulic cylinder A3 can be operated. When the hydraulic cylinder A3 operates, it will drive the push plate 4 to move downward. When the push plate 4 moves downward, it will drive the welding torch 5 to move downward. At the same time, when the push plate 4 moves downward, it will also drive the rack plate 62 to move downward through the fixed rod 61. When the rack plate 62 moves downward, it will drive the movable gear 63 to rotate. When the movable gear 63 rotates, it will drive the threaded rod 64 to rotate. When the threaded rod 64 rotates, it will drive the threaded sleeve 65 to move backward. When the threaded sleeve 65 moves backward, it will drive the housing 8 to move backward. When the housing 8 moves backward, it will drive the sensor to move below the welding torch 5. When the push plate 4 continues to move downward, it will cause the rack plate 62 to move away from the movable gear 63, so that the housing 8 does not continue to move. And the downward moving welding torch 5 will weld the sensor. When the welding is completed, the reverse operation can be carried out to drive the welding torch 5 to move upward. After the welding torch 5 moves upward a certain distance, the rack plate 62 will mesh with the movable gear 63. At this time, the threaded rod 64 can be driven to rotate in the reverse direction, so as to drive the housing 8 to move forward and restore, which is convenient for the staff to take out the welded sensor.
