Abstract
The invention, which belongs to the switch detection technology field, relates to a detection apparatus for service life of a microswitch. The apparatus comprises a sewing machine, wherein an adjustable speed motor drives a needle bar to make up-and-down motions at the sewing machine; and a measuring element and a display are installed at the sewing machine, wherein the measuring element and the display are used for detecting and displaying the number of rotating turns; a microswitch touch pressure plate is fixedly connected at a lower end of the needle bar; and a microswitch positioning frame is localized at a table board below the microswitch touch pressure plate. Beneficial effects of the apparatus are as follows: a sewing machine having an adjustable speed motor is utilized to install a microswitch touch pressure plate and a microswitch positioning frame, so that service life of a microswitch and the pressing number of a microswitch button can be accurately detected; and after the microswitch touch pressure plate and the microswitch positioning frame are removed, the machine can be used as a sewing machine. The apparatus has advantages of multi purposes, simple structure and convenience for using; therefore, the apparatus is suitable for application in a unit that needs detection on service life of a microswitch.
Description
Technical field
The invention belongs to switch detection technique field, refer in particular to a kind of microswitch life detecting device.
Background technology
The manufacturer of sewing machine need adopt a large amount of outsourcing electronics when making sewing machine; For example be used for the microswitch that sewing machine backstitches switch; Mostly from market or producer buying, although some producer provides correlation parameters such as the serviceable life, performance of such switch; It is not too consistent that the technical feature of some switch and instructions are said; Make the manufacturer of sewing machine dare not use the next Switch product of buying easily, after the manufacturer of sewing machine needs oneself in person performance of products to be detected, in the sewing machine that could be applied to relievedly oneself produce.
Summary of the invention
The purpose of this invention is to provide a kind of microswitch life detecting device.
The objective of the invention is to realize like this:
A kind of microswitch life detecting device; Include buncher and drive the sewing machine that the shank work pumps; The measuring sensor and the display that detect and show the motor rotation number of turns are installed on the sewing machine; Be fixedly connected with microswitch in the lower end of shank and press plate, microswitch presses to locate on the table top below the plate has the microswitch locating rack.
Above-mentioned microswitch locating rack is that housing is provided with more than one rectangular through-hole; The sidewall of each rectangular through-hole is provided with pilot hole; Be connected with bolt in the pilot hole; The length of the width >=microswitch of rectangular through-hole, the thickness of the length of rectangular through-hole >=more than one microswitch, the locating rack bottom surface is provided with more than one permanent magnet.
Above-mentioned rectangular through-hole has two, and the pilot hole on the sidewall of two rectangular through-hole is arranged on the same side of housing.
The thickness of the length >=3-10 of an above-mentioned rectangular through-hole microswitch.
Above-mentioned microswitch presses plate can cover all rectangular through-hole.
The present invention compares the outstanding and beneficial technical effects of prior art:
1, utilization of the present invention has buncher and drives measuring sensor and the display that sewing machine that shank does to pump and the motor on the sewing machine rotate the number of turns; The lower end fixed connection microswitch of shank is pressed plate; Microswitch presses to locate on the table top below the plate has the microswitch locating rack; There is measured microswitch the location on the microswitch locating rack again; Start sewing machine, sewing machine needle bar drives microswitch and presses plate and repeatedly the button that presses of microswitch is pushed, and utilizes the arrangements for speed regulation of buncher can adjust the reciprocating speed of shank; Can read the number of times that the motor revolution is promptly known the button of pushing microswitch through display; Because the number of times that motor revolution=shank moves downward=and push the number of times of the button of microswitch, lost efficacy until microswitch, promptly know the life-span size (switch number of times what) of such switch.
2, the present invention removes microswitch and presses plate and microswitch locating rack, on shank, installs eedle and can also make sewing machine use, a tractor serves several purposes.
3, of the present invention simple in structure, the convenient use is applicable to that the unit that needs to detect the microswitch life-span uses.
