Description

A kind of high stability bottleneck gasket hardness measuring device
Technical field
The utility model relates to a kind of high stability bottleneck gasket hardness measuring devices.
Background technique
There is torque design requirement when cooperating between the container finish and bottle cap that blow molding process produces in industry, therefore corresponding The hardness for being encased inside gasket between the two cannot be too big, big that bottleneck or bottle cap is be easy to cause to rupture, certainly can not be too low, low It is easy to cause gasket itself extrusion damaged, therefore its hardness number needs to be maintained in suitable range, that is, meets certain Production standard.So the gasket that producer produces requires to carry out hardness determination.
It is usually all to use Shore durometer cooperation Ding He mechanism branch currently used for the device of detecting pad sheet hardness in industry This set equipment of frame, is set on the base wherein determining lotus mechanism rack, including column, lifting transverse arm, determine lotus counterweight, pressure handle and driving Mechanism.Column is fixed on the base, and lifting transverse arm cooperation is set on column, internal that there is friction pulley to clamp column, it is external then Equipped with the hand gear with friction pulley coaxial design.Determine lotus counterweight to be located above lifting transverse arm, the fixed connecting rod in its underpart passes through lifting Transverse arm is connected with Shore durometer, and the pressing of Shore durometer is opposite with the objective table that lower section is fixed on the base.The pressure handle It is connected with the driving mechanism being arranged in inside lifting transverse arm, which is mainly a set of ripping bar mechanism, which is provided with protrusion Lifting transverse arm is to support the jacking block of counterweight, and when operation, when worker depresses pressure handle, jacking block is removed, and determine lotus counterweight drive shore hardness Meter is pushed to contact with gasket and be measured.
However there are following problems in practical operation for current above-mentioned rigidity detection device:
Since hardness determination requires gasket and stage surface to have very high smoothness and flatness, it is practical to survey Sliding is easy to produce in amount between gasket and objective table, especially when the force imbalance of Shore durometer pressing, gasket Lateral weak vibrations even are had, seriously affect final measurement accuracy.In order to overcome drawbacks described above, at present operation when due to Lack the reliable horizontal clamping mechanism of profession, worker would generally hold stabilizing spacer with hand.But what on the one hand, manpower was held is steady Qualitative difference does not simply fail to effectively prevent gasket sidesway, or even also introduces vertically to pressure, interferes hardness measurement precision;It is another Aspect increases worker operation triviality, time-consuming and laborious, greatly reduces measurement efficiency.And manpower work holds gasket when measuring Also there is certain risk.
Summary of the invention
The utility model aim is: providing a kind of high stability bottleneck gasket hardness measuring device, which can pass through The gasket horizontal clamping mechanism specially designed eliminates the sliding and shaking of gasket, further increases gasket measuring stability, really Final hardness measurement precision is protected, while helping to improve production efficiency, reduces labor intensity of workers.
The technical solution of the utility model is: a kind of high stability bottleneck gasket hardness measuring device, including pedestal, is set to The Shore durometer for determining lotus mechanism rack and be connected with the bracket on pedestal, pedestal are equipped with the objective table for placing gasket, Shao The scleroscopic pressing of family name is opposite with the objective table of lower section;It is characterized in that being additionally provided with gasket horizontal clamping mechanism, the machine on pedestal Structure includes two curved splints symmetrically arranged on the left and the right and drives the two clamping plates to move toward one another with the lead screw driving of grip gasket Device, the lead-screw driving device include screw rod, the servo motor and two nut blocks for installing the screw rod frame of screw rod, connection wire rod, Screw rod is equipped with bilateral symmetry and two sections of oppositely oriented screw threads, this two sections of screw threads and two nut block corresponding matchings are installed, and Two curved splints, which then pass through connection frame and respectively correspond, to be fixed in the two nut blocks;It further include corresponding each nut block setting Guide rail on pedestal is equipped with the guide runner with respective track cooperation in each nut block.
Further, the utility model further includes for incuding the optoelectronic switch for whether placing gasket on objective table, the light Electric switch includes mutually matched receiver and transmitter, they are separately positioned on the holding tank that two curved splints are equipped with It is interior;It further include the PLC controller being electrically connected with optoelectronic switch and the servo motor;When the gasket blocking placed on objective table connects When receiving the light that device reception transmitter issues, optoelectronic switch outputs signal to PLC controller, by PLC controller driving servo electricity Machine drives screw rod rotation so that two curved splint grip gaskets.
Further, any curved splint inner wall described in the utility model is equipped with patch type pressure sensor, should Patch type pressure sensor is electrically connected with PLC controller, outputs signal to PLC when patch type pressure sensor senses gasket Controller is shut down by PLC controller driving servo motor.
Further, screw rod frame described in the utility model includes two pieces of screw rods installation at left and right sides of objective table Plate, screw rod, which pivots, to be set on this two pieces of screw rod mounting plates.
Further, objective table bottom described in the utility model is fixed by the supporting block being set on pedestal, the support Block is equipped with lateral through hole or slot, extends there through for the screw rod.
Further, it is parallel about the nut block that the guide rail of each nut block setting is corresponded to described in the utility model Two be arranged symmetrically, and the guide runner in each nut block is then two pieces, is cooperated respectively with corresponding guide rail.
Further, two curved splints described in the utility model are semicircle clamping plate, can piece together one in opposite directions A circle.Certain design requires the specifications and models of gasket, i.e., the excircle configuration of gasket needs and two semicircle clamping plates Circle after split coincide.
Need to illustrate to determine in the utility model lotus mechanism rack and its with the connection of Shore durometer entirely by reference to existing skill Art, the utility model do not do any improvement.
The working principle of the gasket horizontal clamping mechanism increased newly in the utility model is as follows:
When detection, staff, which adjusts to calibrate first, determines lotus mechanism rack and Shore durometer thereon, and opens PLC Controller, two curved splints are held in initial position at this time.
Worker will be placed on objective table to scleroscopic gasket, due to the blocking of gasket, in one of curved splint Receiver can not receive another side transmitter issue light beam, to trigger optoelectronic switch, and then send a signal to PLC Controller controls servo motor operating, drives screw rod rotation, so that two nut blocks drive curved splint thereon to move toward one another, Slowly grip gasket.After the patch type pressure sensor contacts gasket being mounted on the inside of curved splint, with the increasing of clamping force Add and be triggered, then sends a signal to PLC controller control servo motor and shut down, it is therefore an objective to prevent two sides curved splint from pressing from both sides Clamp force is excessive and gasket is caused to deform, and influences measurement accuracy.Subsequent worker detects according to routine operation with Shore durometer Gasket hardness, and obtain reading.After measurement, drives servo motor to operate again by PLC controller, drive two arcs Clamping plate retracts initial position, and worker removes gasket from objective table.Then repetitive operation carries out the measurement of next gasket.
