Description
Technical field
The utility model relates to a kind of pin instrument that changes of point measurement machine upper sensor.
Background technology
Point measurement machine is a kind of electronic device of electric parameter that obtains electronic product, and the sensor of gathering electric parameter is arranged above it.The probe that a contact electronic component is arranged on this sensor.
As shown in Figure 4, the sensor of point measurement machine comprises pedestal 2.The lower end of pedestal 2 is connecting fixed touching plate 3, and the front end surface of fixed touching plate 3 has one protrudingly to touch 300.A movable contact spring 4 is arranged above fixed touching plate.The rear end of movable contact spring 4 is bonded on the web member 9, and on shell fragment 8, shell fragment 8 is fixed on again on the pedestal 2 web member 9 by screw retention.A limited post 7 is arranged above the pedestal 2, and the upper end of limited post 7 is fixed on the pedestal 2, and movable contact spring is passed in the lower end, is fixed on the fixed touching plate 3.Movable contact spring 4 can move up and down on the post 701 of limited post 7, goes up sports limiting by upper limit chimb 700.On movable contact spring 4, be provided with lower spring axle 402, one end of spring 5 is enclosed within on the lower spring axle 402, the other end is enclosed within on the upper spring axle 600, and upper spring axle 600 is connected the bottom that spring is reconciled bolt 6, and spring conciliation bolt 6 is fixed on the pedestal 2, the top of movable contact spring 4.The bottom of movable contact spring 4, protruding touch 300 above the very thin gold layer 406 of one deck is arranged.Be fixed with pin folder 400 in the end of movable contact spring 4.The front end of pin folder 400 has pin crack 4000, and the pin crack is used to clamp probe, by the fastening probe of screw.
The sensor of this point measurement machine uses frequent, and probe is easy to loss, generally speaking, will change No. one time probe in one day.
Changing needle method at present is: when changing pin, withstand the side that pin presss from both sides with finger, use the screwdriver the turn of the screw, finish and change pin.This method has very big defective.Finger withstands the power of pin folder and uses the dynamics of screwdriver to control, and this power has great uncertainty, in the operating process of actual frequent, can cause the bearing's fracture or the distortion of movable contact spring, thereby cause the damage of sensor or performance to reduce.And, because in changing the process of pin, finger is the error of control in vertical direction, the gold layer 406 that also can cause movable contact spring bottom and fixed touching plate 3 tops protruding touched 300 acutely frictions, very thin gold layer 406 is come off, the surface of contact of movable contact spring 4 and fixed touching plate 3 and contact could be subjected to major injury like this, cause the life-span to be reduced greatly! In addition, finger prosthesis changes very spended time of pin, and the whole pin that changes all needs the thriving operation of extreme care, does not injure movable contact spring as far as possible, changes a pin all more than half an hour.
The sensor of this point measurement machine belongs to exact instrument, and in order to guarantee high-precision requirement, the part of the top connection spring conciliation bolt 6 of pedestal 2 is linked to be an integral body with the fixed touching plate 3 of bottom, and its processed complex, cost are very high.If fixed touching plate or movable contact spring damage, the pedestal part of whole sensor all needs to change.Present such sensor generally is 500 dollars/.The applicant is annual to be needed to change surplus this sensor ten, because the spending of changing this sensor is all more than 5000 dollars.Therefore needing improvement to change needle method reduces enterprise cost and enhances productivity.
The utility model content
Technical problem to be solved in the utility model is: the accessory that a kind of touch sensor is provided, the accessory of this touch sensor can be implemented in when changing pin, make fixed touching plate and movable contact spring keep relative static, stop movable contact spring laterally to move and vertical direction on move, prevent that the damage of movable contact spring and raising from changing pin efficient.
In order to solve this above-mentioned technical matters, the utility model proposes a kind of accessory of touch sensor, the accessory of described touch sensor comprises base plate, on base plate, be provided with and prevent that in the horizontal direction pin from pressing from both sides two located lateral projectioies of relative movable contact spring swing, two grooves that located lateral projection centre adapts for the width with movable contact spring or pin folder; On base plate, also be provided with support protrusion at movable contact spring bottom support movable contact spring.
The preferred version of the accessory of described touch sensor is: described support protrusion is two, respectively from movable contact spring supported on both sides movable contact spring.
The further improvement project of the accessory of described touch sensor is: the accessory of described touch sensor comprises also and is used to the back projection that prevents that floor level from moving that back projection is located on the corresponding position of afterbody of described base plate and described fixed touching plate.
The further improvement project of the accessory of described touch sensor is: be formed with the groove of ccontaining movable contact spring between described two located lateral projectioies, the shape of groove and described movable contact spring are suitable.
The beneficial effects of the utility model are as follows:
What compared to existing technology, the utility model provided the manually-operated touch sensor of a kind of confession changes the pin accessory.Have on the accessory of this touch sensor and can prevent that in the horizontal direction pin from pressing from both sides two located lateral projectioies of relative movable contact spring swing and being used to support the support protrusion of movable contact spring, the staff with the accessory of touch sensor below fixed touching plate, after putting fixed touching plate and movable contact spring, owing to of the clamping qualification effect of two located lateral projectioies to the both sides of movable contact spring, movable contact spring fixed touching plate generation teeter relatively, the place that is connected with web member of the root of the movable contact spring torsion that just can not rotate like this, deformation takes place in the rear portion that can well prevent movable contact spring, with the precision that holding point is surveyed, can well prevent that also movable contact spring from coming off because of torsion from the web member.In addition, because support protrusion is at movable contact spring bottom support movable contact spring, the staff is in changing the process of pin, movable contact spring moves down and is obstructed, and unlike prior art, the jitter amplitude of following finger carries out the motion on the excessive vertical direction, can avoid the protruding scraping of transfiniting with the gold layer of touching so significantly.In actual application, no matter be located lateral projection or support protrusion, its position-limiting action to movable contact spring is very obvious, and the spacing size of its control is controlled little more than finger, and then can realize movable contact spring and sensor are farthest protected.In addition, the utility model is because the control movable contact spring is more easy, therefore greatly height change the efficient of pin, the efficient of changing pin shortened to a few minutes by former half an hour.
