Abstract
Description
Technical Field
[0001] The utility model relates to the field of sensor manufacturing equipment, in particular to a sensor needle seat laser welding tool. 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.
[0003] During the production process of the sensor, the needle seat needs to be welded to the sensor, and the power supply and bed input model are connected through the pins. When welding the pins, the sensor needs to be manually fixed, and then the pins are welded. If the needle seat assembly becomes cheap or falls off during the welding process, it will cause welding failure and the sensor will not work properly. Therefore, a tooling is required that can fix the needle seat when the welding bed is dry. Utility Model Content
[0004] The present invention aims to solve the technical problems mentioned in the above background technology and proposes the following technical solutions:
[0005] A sensor needle seat laser welding tool includes two semicircular sleeves and a fixed sleeve. The two semicircular sleeves are of the same size and shape and can be spliced into a cylindrical sleeve structure. A first semicircular hole is provided in the middle of the semicircular sleeve, and a second semicircular hole is provided at the bottom of the first semicircular hole. A circular hole is provided in the middle of the fixed sleeve. The fixed sleeve is fitted on the outer circumference of the two semicircular sleeves, and two positioning holes are symmetrically provided on the fixed sleeve.
[0006] Preferably, the top edge of the first semicircular hole is a bevel structure.
[0007] Preferably, a groove is provided on the inner wall of the first semicircular hole, a limiting plate is provided in the groove, a plurality of springs are provided on one side of the limiting plate, one end of the plurality of springs is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the bottom of the groove.
[0008] Preferably, the limiting plate is an arc-shaped structure.
[0009] Preferably, a rubber pad is provided on one side of the limiting plate.
[0010] Preferably, a plurality of shrapnel grooves are provided on the inner wall of the circular hole, and metal shrapnel are provided in the plurality of shrapnel grooves.
[0011] The beneficial effects of the utility model are:
[0012] 1. By setting two semicircular sleeves, clamping the needle seat assembly by the two semicircular sleeves, and then fixing the two semicircular sleeves by a fixing sleeve, the problem that the needle seat assembly is difficult to clamp and easily skews during welding can be solved.
[0013] 2. By setting a groove on the inner wall of the first semicircular hole and setting a limit plate connected to the spring in the groove, the needle seat assemblies of different sizes can be clamped by the expansion and contraction of the spring, solving the problem of being unable to clamp or tighten due to the different sizes of the needle seat assemblies.
[0014] 3. By setting a metal shrapnel on the inner wall of the circular hole, the two semicircular sleeves can be made to fit more tightly through the metal shrapnel, avoiding the problem of the two semicircular sleeves loosening during the welding process, which causes the needle seat assembly to be skewed.
