Abstract
A force metering gauge used for detecting a separating force of a relay reed comprises a frame body, a force value adjusting unit and a probe, wherein the force value adjusting unit arranged inside the frame body; the probe is erected on a top portion of the frame body, and small V-shaped bottom portions at two sides of the probe are arranged in large V-shaped top portions at two sides of the frame body, the probe being capable of swinging slightly at the top portions of the frame body; and a middle position of a bottom portion of the probe is connected with a top portion of the force value adjusting unit through a connecting piece. The force metering gauge of the utility model is advantageous in that: the small V-shaped bottom portions at the two sides of the probe are arranged in the large V-shaped top portions at the two sides of the frame body, such that the probe bears extremely small friction when the probe swings relative to the frame body, and the force value of the swinging of the probe is almost unchanged, thereby greatly facilitating the improvement of detection accuracy; and without manual numeric reading required, the qualification or disqualification of a detection result can be judged intuitively through separated and unseparated states of the reed when the probe swings.
Description
Technical field
The utility model relates to a kind of testing tool, specifically a kind ofly opens testing fixture for testing force from power for detection of relay spring.
Background technology
Reed leaves from the numerical values recited of power in the relay generally requirement, therefore need to open from this parameter of power relay spring and detect.Traditional detection mode is to utilize gram force meter direct-detection, and then artificial reading draws the power value, though this detection mode can be finished the detection of power value, has not intuitively problem of testing result.Therefore, existing relay spring is opened from the force measurements technology and is awaited to improve.
Summary of the invention
The purpose of this utility model provide a kind of can intuitively reflect testing result open testing fixture for testing force from power for detection of relay spring.
For achieving the above object, technical solution adopted in the utility model is: a kind ofly open testing fixture for testing force from power for detection of relay spring, comprise framework, power value regulon and probe, power value regulon is positioned at framework inside; Probe carriage is located at the framework top, and the little V-type bottom of probe both sides places the large V-type top of framework both sides, and probe can slightly swing at the framework top; The centre position of probe base is connected by the top of web member with power value regulon.
Described power value regulon is comprised of screw rod, spin part and extension spring, and screw rod passes the threaded hole of framework bottom; The screw rod top is connected with the extension spring bottom by the part that spins.
Use-pattern of the present utility model is: at first, utilize the gram force meter calibrating, by power value regulon the oscillatory forces of the utility model probe is preset as the desired minimum of relay spring and opens from the power value; Then, utilize the utility model after the calibration adjustments that relay spring is opened from force measurements, if in the situation that probe slightly swing relay spring do not open from, then relay spring open from power qualified, otherwise defective.
The beneficial effects of the utility model are: because the little V-type bottom of probe both sides places the large V-type top of framework both sides, so that the friction force that the relative framework of probe is subject to when swinging is minimum, the power value size of impelling probe to swing is almost constant, with the accuracy that is very beneficial for detecting; Whether testing result is qualified need not artificial reading again and draws the power value and judge, but whether reed is opened from and intuitively drawn when swinging by probe.
Description of drawings
Fig. 1 is structural representation of the present utility model.Each label is respectively among the figure: (1) framework, (2) power value regulon, (3) probe, (4) little V-type bottom, (5) large V-type top, (6) web member, (7) screw rod, (8) part that spins, (9) extension spring.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, a kind of relay testing fixture for testing force of the utility model comprises framework 1, power value regulon 2 and probe 3, and power value regulon 2 is positioned at framework 1 inside; Probe 3 is set up in framework 1 top, and the little V-type bottom 4 of probe 3 both sides places the large V-type top 5 of framework 1 both sides, and probe 3 can slightly swing at framework 1 top; The centre position of probe 3 bottoms is connected with the top of power value regulon 2 by web member 6.Described power value regulon 2 is comprised of screw rod 7, spin part 8 and extension spring 9, and screw rod 7 passes the threaded hole of framework 1 bottom; Screw rod 7 tops are connected with extension spring 9 bottoms by the part 8 that spins.
