For the ease of pulling pull bar, lifted by briquetting, assembling measured piece, the upper end of described pull bar is provided with handle.
In order to carry out spacing to spring, prevent spring lateral deviation, affect the accuracy of elastic force, below described back-up ring, be provided with the bushing of cylindricality.
Keyswitch contact of the present utility model supports that the advantage of pick-up unit is: keyswitch contact of the present utility model supports that structure of the detecting device is simple, low cost of manufacture, easy to use, keyswitch contact can be tested fast and whether meet standard, detect accuracy is high, solve in prior art and adopt spring dynamometer cost high, inefficient problem.Namely when briquetting is added on keyswitch with certain pressure, the displacement of keyswitch is greater than certain height, only have when displacement is greater than the height of regulation, the contact of keyswitch could realize disjunction, keyswitch is only pieces O.K., when reality uses, can with using the reference block with standard thickness through the space mark circle and support, if reference block is worn to pass by, illustrate that measured piece is pieces O.K., if can through going, illustrate that the displacement of keyswitch is inadequate, measured piece be unacceptable product.
Accompanying drawing explanation
Fig. 1 is the structural representation that keyswitch contact of the present utility model supports pick-up unit;
In figure, 1 is base plate, and 2 is support, and 3 is posting, and 4 is guide pin bushing, and 5 is depression bar, and 6 is back-up ring, and 7 is briquetting, and 8 is mark circle, and 9 is spring, and 10 is threaded line pipe, and 11 is setting nut, and 12 is set nut, and 13 is pin, and 14 is pull bar, and 15 is handle, and 16 is bushing.
Embodiment
Pick-up unit is supported with reference to a kind of keyswitch contact shown in Fig. 1, it comprises base plate 1, be fixedly connected on the support 2 on base plate 1, be arranged on the posting 3 for locating to be measured on base plate 1, be arranged on the guide pin bushing 4 on support 2, the depression bar 5 passed in guide pin bushing 4 and the calibration assemblies that depression bar 5 is calibrated, cavity is provided with in guide pin bushing 4, upper end in guide pin bushing 4 is provided with back-up ring 6, back-up ring 6 center has hole, the lower end of depression bar 5 is provided with briquetting 7, the top of briquetting 7 certain altitude of being separated by is provided with mark circle 8, the spring 9 with certain elastic force is provided with between mark circle 8 and the lower surface of back-up ring 6, described calibration assemblies comprises threaded line pipe 10, the setting nut 11 be fixedly connected with threaded line pipe 10 and be arranged on threaded line pipe 10 with threaded line pipe 10 threaded engagement set nut 12, set nut 12 lower end is fixedly connected with back-up ring 6, threaded line pipe 10 passes from the hole of back-up ring 6, threaded line pipe 10 coordinates with this interporal lacuna, set nut 12 is arranged on the top of back-up ring 6, the top of depression bar 5 is fixedly connected with the pull bar 14 of top by pin 13, the size of pin 13 is greater than the internal diameter of threaded line pipe 10 and is less than the diameter in the hole of back-up ring 6.
For the ease of pulling pull bar 14, lifted by briquetting 7, assembling measured piece, the upper end of described pull bar 14 is provided with handle 15.
In order to carry out spacing to spring 9, prevent spring 9 lateral deviation, affecting the accuracy of elastic force, below described back-up ring 6, be provided with bushing 16 of cylindricality.
Keyswitch contact of the present utility model supports pick-up unit in use, spanner is first used to rotate setting nut 11, threaded line pipe 10 is rotated, because set nut 12 and threaded line pipe 10 threaded engagement, and indentation nut is fixedly connected with back-up ring 6, so when rotating threaded line pipe 10, threaded line pipe 10 can move up and down relative to guide pin bushing 4, because be connected by pin 13 with pull bar 14 with depression bar 5, the diameter of pin 13 is greater than the internal diameter of threaded line pipe 10 and is less than the diameter in the hole in guide pin bushing 4, so threaded line pipe 10 moves up and down in process, depression bar 5 can move up and down thereupon, can be calibrated the height of depression bar 5 by this adjustment, the pressure be applied on briquetting 7 is made to reach the normal pressure of test, pull bar 14 is pulled to be lifted by briquetting 7, measured piece is contained on posting 3, then releasing lever 14, under spring 9 acts on, briquetting 7 drives depression bar 5 to move down, be pressed on measured piece, the button of keyswitch moves down under the pressure effect of briquetting 7.Because when only having the displacement when keyswitch to be greater than the height of regulation, the contact of keyswitch could realize disjunction, keyswitch is only pieces O.K., so when reality uses, the reference block with standard thickness can be used through the space mark circle 8 and support 2, if reference block is worn to pass by, illustrate that the displacement of measured piece is greater than the height of regulation, illustrate that measured piece is pieces O.K., if can through going, illustrate that the displacement of keyswitch is inadequate, measured piece is unacceptable product.Keyswitch contact of the present utility model supports that structure of the detecting device is simple, and low cost of manufacture, detection efficiency is high, is more suitable for applying.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes all should be included into scope of patent protection of the present utility model.
