Abstract
The utility model belongs to the technical field of switch detection, and relates to a microswitch service life detector. The microswitch service life detector comprises a sewing machine with a speed-changing motor, a needle bar of the sewing machine is driven by the speed-changing motor to do vertical reciprocating movement, the sewing machine is provided with a measuring element and a display which are used for detecting and displaying rotation circles of the motor, a microswitch touch platen is fixedly connected at the lower end of the needle bar, and a microswitch positioning frame is positioned on a table top below the microswitch touch platen. The microswitch service life detector has the technical benefits that: the sewing machine with the speed-changing motor is additionally provided with the microswitch touch platen and the microswitch positioning frame, so that the service life of a microswitch and the times of pressing buttons of the microswitch can be accurately detected; and the detector can be used as a sewing machine after the microswitch touch platen and the microswitch positioning frame are removed, so that the detector has multiple functions and a simple structure, and is convenient to use and applicable to units needing to detect the service life of the microswitch.
Description
Technical field
The utility model belongs to switch detection technique field, refers 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 the serviceable life of such switch, correlation parameters such as performance, but, 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 the performance of product to be detected, in the sewing machine that could be applied to relievedly oneself produce.
Summary of the invention
The purpose of this utility model provides a kind of microswitch life detecting device.
The purpose of this utility model is achieved in that
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 on the table top of plate below and is positioned with 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 utility model gives prominence to compared to existing technology and beneficial technical effects is:
1, utilization of the present utility model has buncher and drives shank and make measuring sensor and the display that the sewing machine that pumps and the motor on the sewing machine rotate the number of turns, the fixedly connected microswitch in the lower end of shank is pressed plate, microswitch presses on the table top of plate below and is positioned with the microswitch locating rack, on the microswitch locating rack, be positioned with measured microswitch again, start sewing machine, sewing machine needle bar drive microswitch presses plate and repeatedly the button that presses of microswitch is pushed, utilize 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 by display, because the number of times that motor revolution=shank moves downward=push the number of times of the button of microswitch, lost efficacy until microswitch, promptly knew the life-span size (switch number of times what) of such switch.
2, the utility model removes microswitch and presses plate and microswitch locating rack, installs eedle and can also make sewing machine use, a tractor serves several purposes on shank.
3, of the present utility model simple in structure, the convenient use is applicable to that the unit that needs to detect the microswitch life-span uses.
Description of drawings
