Embodiment
[0028] see Figures 1 to 2 , the microswitch and the microswitch part 15 to be tested composed of a microswitch and a plurality of microswitches are schematically shown in the figure, each microswitch includes a first contact part 16 that can be in contact with the detection block 7, and is in contact with the probe The second contact portion 17. The micro switch component 15 also includes an insulating housing 18 in addition to a plurality of the above micro switches.
[0029] Please also refer to Figures 3 to 4 , a device for judging the height consistency of multiple groups of micro switches in an automobile combination switch, which is composed of an upper mold and a lower mold.
[0030] Wherein, the upper mold includes a mold handle 1, and the mold handle 1 is screwed on the mold handle plate 4, and is locked with a set screw 2, and the fixed plate 5 is fastened below the mold handle plate 4 by screws. A set of L-shaped conductivity detection blocks 7 and a set of cond...

The invention discloses a method for determining the height consistency of multiple groups of micro switches in an automobile combination switch, and the method comprises the following steps: A. a microswitch part to be measured is placed in a lower die of a measuring apparatus; B. an upper die descends, a probe firstly contacts with a microswitch, a upper die continuously descends, till a detection block contacts a lower limit surface of a gauge block, and the upper die stops descending; if a LED laminates, the determination result is that the combination switch is qualified, and a next step is carried out, otherwise, the determination result is that the combination switch is not qualified; C. the upper die ascends, and the step is pushed to the upper part of the lower limit surface of the gauge block; the height of the step is a difference between the upper limit and the lower limit of the fluctuation permitted by a micro switch height; D. the upper die descends downwards to the upper limit surface of the gauge block, if the LED does not illuminates, the determination result is that the combination switch is qualified, and the test ends; otherwise, the determination result is that the combination switch is not qualified. According to the invention, defects including big measuring errors of the original height verniercalliper and low efficiency are avoided; the invention has the advantages of simple structure, saved labor and time, high measuring precision, etc., and actual production demands are met.
Description
technical field [0001] The invention relates to the field of height measurement of multiple groups of microswitches in an automobile combination switch, in particular to a method for measuring and judging the height consistency of a group of microswitches. Background technique [0002] At present, the height consistency of a group of micro switches in the automobile combination switch is determined. The vernier height caliper is used to measure the height data of the micro switches one by one, and then determine whether the consistency is within the allowable tolerance range. That is, on a smooth and horizontal workbench, put a vernier height caliper and a positioning block of standard height, put a group of micro switch parts on the positioning block, and then move the vernier height caliper, when the marking claw and When the highest point of one micro switch touches, read the scale data on the vernier height caliper, and so on, measure the highest point data of other micr...
