Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a welding fixture of a sensor. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. During the assembly process of the sensor, a fixture is usually used to accurately position and fix the sensor so that the required components can be assembled on the sensor.

[0003] The existing sensor welding fixtures have poor versatility and unbalanced force when pressed, which causes the sensor to be easily deformed due to thermal expansion during the welding process, further limiting the improvement of the sensor's accuracy. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a welding fixture for a sensor.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a welding fixture for a sensor, comprising a base plate, a lift is provided on the surface of the base plate, a screw is provided on the surface of the lift, a screw is provided inside the screw, a cylinder is provided on the surface of the base plate, a support plate is provided on the top of the cylinder, a sensor is provided on the surface of the support plate, a connecting rod is provided on the surface of the support plate, a pressure plate is provided on the top of the connecting rod, a follower is provided on the surface of the follower, a floating block is provided on the surface of the floating block, and a joint bearing is provided on the surface of the floating block.

[0006] Preferably, two floating blocks are axially symmetrically arranged, and the two floating blocks are rotatably connected to the screw via a joint bearing.

[0007] Preferably, a movable groove is provided at the bottom of the floating block, and the floating block is rollingly connected to the follower through the movable groove.

[0008] Preferably, two connecting rods are axially symmetrically arranged, and the two connecting rods are movably connected to the support plate.

[0009] Preferably, the cylinder is axially symmetrically arranged on the surface of the base plate, and the pressure plate is axially symmetrically arranged on the surface of the connecting rod.

[0010] Preferably, a sliding groove is provided on the surface of the pressing plate, and a fastener is provided on the side of the pressing plate.

[0011] Preferably, the sensor is arranged at a central position of the support plate, and the top of the sensor abuts against the fastener.

[0012] Beneficial Effects

[0013] In the utility model, a joint bearing, a follower and a pressure plate are adopted. Since the joint bearing has the ability to swing in the axial direction, the followers on both sides can move freely in the floating block. The floating structure of the joint bearing and the follower stroke can make the pressure under the pressure plates on both sides balanced, thereby controlling the deformation during welding, and adjusting the extension amount of the pressure plate with the slide groove, so that it can adapt to sensors of different sizes, ensuring the improvement of the sensor accuracy.

There are two floating blocks 9 axially symmetrically arranged, and the two floating blocks 9 are rotatably connected with the screw 8 through the joint bearing 11. When the screw 8 moves downward, the joint bearing 11 is driven to move downward, so that the floating block 9 moves downward, and the floating block 9 further pushes the two followers 10, and further the two followers 10 respectively drive the connecting rod 5 to move downward, so that the pressure plate 6 fixed on the connecting rod 5 is pressed on the sensor 7.

[0024] The sensor 7 is placed at the center of the support plate 4, and the manual screw elevator 3 is used, and under the transmission of the internal worm gear, the screw 12 on the screw elevator 3 is translated downward, further driving the screw 8 to move downward, and then driving the joint bearing 11 to move downward, so that the floating block 9 moves downward, and the floating block 9 further pushes the two followers 10, and the two followers 10 further drive the connecting rod 5 to move downward respectively, so that the pressure plate 6 fixed on the connecting rod 5 is pressed on the sensor 7, and the joint bearing 11 has the ability to swing axially, and the followers 10 on both sides can move freely in the floating block 9, so that the force of the pressure plates 6 on both sides is balanced when pressing down.
