As depicted in figs. 1 and 2, a kind of detection jig of machine tooling clamping device, including upper jig 1, elastic force detection dress Set 2 and lower jig 3, workpiece 4 to be detected is circular ring shape or the different shapes such as rectangular, detects the applicable work of different shapes of jig Part 4, upper jig 1 and lower 3 phase of jig are equipped with the step of socket workpiece 4 inwardly, and step can be rectangular or round, jig under choosing 3 surface is clamping face, and upper jig 1 divides for upper cover 11 and lower cover 12, and detection device for elasticity 2 is installed on upper cover 11 and 12 groups of lower cover Intracavitary in, detection device for elasticity 2 is moved down with upper jig 1, and workpiece 4 clamps positioning, bullet by upper jig 1 and lower jig 3 Force checking device 2 detects workpiece 4, and whether clamping is accurate, and detection device for elasticity 2 is at least provided with 1, and preferably 5, elastic force detection 2 circumference equal dividing cloth of device is mounted on 1 inner cavity of jig, and detection device for elasticity 2 can increase according to actual needs.

As shown in figure 3, the embodiment one of elastic force apparatus: detection device for elasticity 2 includes 21,2 23 and of spring needle of probe Fixed block 22, probe 21 are threadedly coupled fixed block 22, and fixed block 22 is installed on inside jig 1, pacifies at left and right sides of fixed block 22 Shock mount needle 23, spring needle 23 can be chosen on the market, and spring needle 23 is preferably 2, can increase according to actual needs Subtract, 23 one end of spring needle is in contact with fixed block 22；The other end is in contact with upper 1 inner cavity top of jig, and probe 21 is equipped with detection Scale, 21 tail portion of probe are stretched out from upper 1 bottom of jig.The workpiece 4 of annular is sleeved on the upper positioning of lower jig 3, upper jig 1 in advance It moves down and clamps workpiece 4, while upper jig 1 drives probe 21 to be in contact with lower 3 clamping face of jig by spring needle 23, if workpiece 4 Clamping is bad, and 21 stress of probe protrudes into inside jig 1, to judge that workpiece 4 is undesirable.

As shown in figure 4, the embodiment two of elastic force apparatus: detection device for elasticity 2 is including 21,2 springs 24 of probe and admittedly Determine block 22, probe 21 is threadedly coupled fixed block 22, and fixed block 22 is installed on inside jig 1, installs at left and right sides of fixed block 22 Spring 24, spring 24 preferably have 2, can increase and decrease according to actual needs, and 24 one end of spring is in contact with fixed block 22；The other end with Upper 1 inner cavity top of jig is in contact, and probe 21 is equipped with detection scale, and 21 tail portion of probe is stretched out from upper 1 bottom of jig.The work of annular Part 4 is sleeved on lower jig 3 in advance and positions, and upper jig 1, which moves down, clamps workpiece 4, while upper jig 1 drives probe by spring 24 21 are in contact with the clamping face of lower jig 3, if 4 clamping of workpiece is bad, 21 stress of probe is protruded into inside jig 1, to judge Workpiece 4 is undesirable.

As shown in figure 5, the embodiment three of elastic force apparatus: detection device for elasticity 2 is including 21,1 springs 24 of probe and admittedly Determine block 22, probe 21 is threadedly coupled fixed block 22, and fixed block 22 is installed on inside jig 1, and spring 24 has 1 and is set in spy 21 lower section of needle, 24 one end of spring and 22 bottom connection of fixed block touch, and the other end is in contact with upper 1 intracavity bottom of jig, probe 21 Equipped with detection scale, 21 tail portion of probe is stretched out from upper 1 bottom of jig.The workpiece 4 of annular is sleeved on the round platform of lower jig 3 in advance It being positioned on rank, upper jig 1, which moves down, clamps workpiece 4, and probe 21 is in contact with the clamping face of lower jig 3, if 4 clamping of workpiece is bad, 21 stress of probe protrudes into inside jig 1, to judge that workpiece 4 is undesirable.

Testing result can be more intuitively observed for the ease of user, and jig further includes carrying out intuitively to testing result The judgment means of judgement, judgment means include conducting wire, power supply and attention device, and attention device is built in LED light or buzzer or lathe Alarm module, attention device is electrically connected probe by conducting wire, when 4 clamping of workpiece is normal, after probe contacts lower 3 surface of jig, Power drives LED light or buzzer sound an alarm, and visual cues user product can normal use or the warning built in lathe Module reminds user's product can normal use；When 4 clamping of workpiece is abnormal or oversized, probe cannot be with lower jig 3 Clamping face is in contact, and attention device is failure to actuate, and visual cues user's product is bad.

As shown in fig. 6, detection device for elasticity 2 is also mountable to lower jig 3, probe 21 is stretched out from lower 3 top of jig and work The ring side of part 4 is in contact.In addition, as shown in fig. 7, detection device for elasticity 2 can also be mounted on simultaneously in jig 1 and lower jig 3, Whether clamping is bad for detection workpiece together.It links as shown in figure 8, detection jig is realized by microswitch 5 and lathe, when removing After detecting jig, detection jig no longer compresses microswitch 5, and lathe cannot start, and prevent from processing caused by starting suddenly because of lathe Accident；After detection jig is loaded onto, detection jig compresses microswitch 5, and lathe can normally start.

The working principle of the invention: it is illustrated for detecting the workpiece 4 that tolerance is ± 0.05mm, first takes a standard Qualified workpiece 4 is used as standard, and pre-installation is located in the step cutting pattern of lower jig 3, and upper jig 1 is moved down to be in contact with workpiece 4, The length that probe 21 stretches out lower cover 12 is adjusted, so that probe 21 and the clamping face of lower jig 3 is in contact, attention device will issue letter Number, at this point, the distance of probe 21 to lower jig 3 is exactly to detect benchmark, when 4 clamping of workpiece to be detected is not in place so that being higher by public affairs When poor range, probe 21, which moves down, to be contacted with lower jig 3, and attention device does not work, and judge that workpiece 4 is excessively high；If work need to be detected Part 4 is too low, probe 21 can be turned down ﹣ 0.05mm, and testing principle and detection workpiece 4 are excessively high similar.In addition, upper jig 1 can be adopted With power source drives such as cylinder or magnet, it is moved down, and workpiece 4 can quick and precisely be clamped by guaranteeing to move down every time.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that Specific implementation of the invention is only limited to these instructions, for those of ordinary skill in the art to which the present invention belongs, Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention Protection scope.
