Description

Technical Field

[0001] The utility model belongs to the technical field of switches, and in particular relates to a tooling for switch clamping and power-on detection. Background Art

[0002] The switch is composed of a base, a nozzle, a push rod, a spring, a button, and a bushing. Due to the reaction force of the spring, each part and component is in a dispersed state before laser welding. The prior art is to tighten the switch with a screw sleeve, place it on a vise, rotate the stroke measuring device, and judge the parameter value of the switch by listening to the sound of the switch switching. However, the instantaneousness of the switch cannot be detected by listening to the sound, and can only be checked by powering on after the wires are brazed and the connectors are installed. This results in that when the switch is found to have instantaneousness after the power-on inspection in the later stage, the inside of the switch mechanism has been glued and fixed, and the switch components have been laser welded and cannot be repaired, and the entire switch can only be scrapped, resulting in high production costs and serious waste. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a switch clamping and power-on detection tooling with a high pass rate and low production cost, which can visually detect the switch before welding the wire, detect and eliminate instantaneous switches in advance, reduce the rework and scrapping of unqualified switches that can only be detected in subsequent processes, and provide a switch clamping and power-on detection tooling with a high pass rate and low production cost.

[0004] The purpose of the utility model and the solution of its main technical problems are achieved by adopting the following technical solutions:

[0005] The utility model discloses a tooling for switch clamping and power-on detection, comprising a panel, a pressure block, a pad, a foot, a support sleeve and a probe, and is characterized in that the panel is connected to the upper end of the foot, the middle part of the foot is connected to the pad, the lower end is inserted into the support sleeve and screwed in, the center of the foot is equipped with a probe, and the pressure block is inserted into a hole arranged on the side of the panel.

[0006] A perforation is provided at the center of the panel.

[0007] A U-shaped groove is arranged at one end of the pressing block.

[0008] Compared with the prior art, the utility model has obvious beneficial effects; from the above technical scheme, it can be known that: the upper end of the foot is connected through the panel, the middle part of the foot is connected to the pad, the lower end is inserted into the support sleeve and screwed in, a probe is installed in the center of the foot, and a pressure block is inserted into the hole set on the side of the panel. The plane of the pad is used as the reference plane for measuring the switch, and a retractable probe is installed in the center of the pad. The position of the probe is in contact with the two switch pins in the pipe nozzle. The 8 probes are connected to the control box through 8 wires for power-on inspection. The pressure block is inserted into the square hole set on the side of the panel. The height from the position of the square hole to the plane of the pad is the distance from the switch base to the pipe nozzle groove. The pressure block is designed as a U-shaped groove structure, and its size matches the pipe nozzle groove. Rotate the screw sleeve to tighten the bushing-pipe nozzle combination, and then insert the pipe nozzle assembly into the measuring device so that the base pin in the pipe nozzle assembly contacts the probe, and continue to press down until the base plane is flush with the lower pad plane. The pressure block is inserted into the panel, and the switch is tightened by fitting the U-shaped groove of the pressure block to the pipe nozzle groove. After adjusting the parameters, two points are punched 180° symmetrically at the joint between the screw sleeve and the pipe nozzle for pre-tightening, and a circle is welded at the interface between the screw sleeve and the pipe nozzle using laser welding. This enables visual power-on detection of the switch before welding the wires, and detects and removes instantaneous switches in advance, reducing rework and scrapping of unqualified switches that can only be detected in subsequent processes. This has a high pass rate and low production costs. BRIEF DESCRIPTION OF THE DRAWINGS
