Abstract
The utility model aims at providing an error-proofing and positioning mechanism of a clamp, which can realize difference error-proofing of a punching piece simultaneously when the punching piece is positioned. The error-proofing and positioning mechanism of the clamp comprises a positioning pin boss which is internally provided with a cavity with opened bottom and top; the cavity is internally provided with a spring positioning pin, the top of which can extend out of the cavity along the opening at the top of the cavity; and the key point is that the positioning pin boss is provided with a sensor used for sensing the position of the spring positioning pin beside the opening at the bottom of the cavity. When the mechanism is used, the spring positioning pin is extruded out of the positioning pin boss to play an indicating positioning role, when a workpiece to be tested is installed on the spring positioning pin, the spring positioning pin is pressed by the workpiece to move downwards in the cavity, when the spring positioning pin moves to the preset position, the sensor senses that the spring positioning pin approaches, and the situation that the workpiece to be tested is arranged above the positioning pin boss can be shown, thus realizing the error-proofing function.
Description
Technical field
The utility model belongs to anchor clamps manufacturing technology field, specially refers to a kind of a kind of anchor clamps mistake proofing detent mechanism of the Flexible Production line that is used to be welded.
Background technology
In the production process that is welded; The planning of production line more and more trends towards flexibility; Increasing difference part has appearred in the process of Flexible Production, and the difference part many assembly unit mistake of difference part just appears easily, therefore; Stamping parts not only need be located on soldering cramping apparatus, also wants mistake proofing in the time of the location.At present a lot of companies carry out mistake proofing through utilizing the method for widely applying sensor to respond to stamping parts profile difference, but the general error of profile difference of stamping parts is very big, the adjustment difficulty, and therefore above-mentioned error-preventing method reliability is relatively poor.
Summary of the invention
The purpose of the utility model is to propose a kind of anchor clamps mistake proofing detent mechanism, in to the stamping parts location, realizes the mistake proofing of stamping parts difference.
The anchor clamps mistake proofing detent mechanism of the utility model comprises location key seat; The cavity that has a top and bottom opening in the said location key seat; Be movably installed with a spring holder in the said cavity; The top of said spring holder can be stretched out outside the cavity along the cavity open top, and key is that said location key seat is equipped with a sensor that is used for perception spring holder position at the side of cavity bottom opening.
In use, spring holder protrudes in location key seat, plays the effect of indication location; When workpiece to be detected is installed on the spring holder; Spring holder will be moved down in cavity by this workpiece compressing, and after moving to the precalculated position, it is approaching that sensor will perceive spring holder; Promptly represent that the location key seat top is equipped with workpiece to be detected this moment, thereby realize error-disable function.
Specifically, said spring holder comprises shank, and the sidepiece of said shank is provided with outstanding limiting section, is with spring on the said shank, and the top of said spring and limiting section bottom surface offset, and the bottom of spring and the bottom surface of cavity offset.When workpiece to be detected is not installed on spring holder; Shank under the effect of spring away from the sensor below it; Therefore sensor detects the existence less than alignment pin; When workpiece to be detected and spring holder being installed by the compressing of this workpiece and after in cavity, being moved downward to the precalculated position, it is approaching that sensor will perceive spring holder on the spring holder.
Further, said location key seat links to each other with an anchor clamps connecting plate, is used for location key seat is connected with anchor clamps.
Further, said sensor be metal near switch, enter into the investigative range of metal switch when metal shank after, metal switch can send switching signal to alarming device or control device, the expression spring holder put in place.
The anchor clamps mistake proofing detent mechanism of the utility model is through being provided with sensor in location key seat; Make the conventional positioning key seat on the basis of realizing positioning function; Simultaneously possessed error-disable function again, be fit to be applied in the car body welding producing line, particularly the location of stamping parts and difference mistake proofing aspect.
Description of drawings
Fig. 1 is the structural representation of the anchor clamps mistake proofing detent mechanism of the utility model.
The specific embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
As shown in Figure 1; The anchor clamps mistake proofing detent mechanism of present embodiment comprises location key seat 1; The cavity 2 that has a top and bottom opening in the location key seat 1; Be movably installed with a spring holder 3 in the cavity 2, the top 3 of spring holder can be stretched out outside the cavity along cavity 2 open tops, and location key seat 1 is equipped with a metal that is used for perception spring holder 3 positions near switch 4 at the side of cavity bottom opening.
With the automobile assembling is example, and the automobile front floor longeron that has does not have stiffener, and the preceding longitudinal floor beam that has then has stiffener, and stiffener and longeron originally were the concentric hole co.As shown in Figure 1, in use, spring holder 3 protrudes in location key seat 1, the installation of preceding longitudinal floor beam 6 is played the effect of indication location.When on spring holder 3, stiffener 7 not being installed, shank under the effect of spring 32 away from the metal below it near switch 4, so metal detects the existence less than spring holder 3 near switch 4; Stiffener 7 and spring holder are installed and after in cavity, being moved downward to A place, precalculated position by the compressing of this workpiece on spring holder 3; It is approaching that metal will perceive spring holder 3 near switch 4; Represent promptly that spring holder seat 3 tops are equipped with stiffener 7 this moment, thereby realize error-disable function.
Above-mentioned anchor clamps mistake proofing detent mechanism can utilize the hole to realize mistake proofing, and the distance sensing that produces like this can increase, and also can increase the reliability of sensor greatly, thereby increases the reliability of mistake proofing.In addition, present embodiment can also be used for the error prevention means of common production line, and is simple and practical, realizes easily, needn't waste a large amount of automation equipments, thereby practices thrift cost.
