Abstract

A measuring jig is used for measuring exposure size of a metal head of a wire rod and comprises a base plate, a dialgage and a contact block. A first containing groove and a second containing groove are arranged on the base plate, and the dialgage is arranged in the first containing groove and comprises a sleeve, a measuring bar, a dial plate and an inner transmission structure. The measuring bar moves in the sleeve, the dial plate is provided with an indicator and scales, the contact block is arranged in the second containing groove and connected with the base plate, and a groove is arranged on the contact block to be used for one end of the measuring bar and the exposed metal head of the wire rod to penetrate through. When in measurement, the measuring bar is perpendicular to the exposed metal head, and the measuring bar and the exposed metal head are on a same measuring plane. When the measuring jig is used for measuring the exposure size of the metal head of the wire rod, measurement is accurate and reliable by using the dialgage, and the contact block is used for the exposed metal head to penetrate through, so that the contact surface is unit and measuring efficiency is higher.

Description

Measure tool

[technical field]

The utility model relates to a kind of measurement tool, and particularly a kind of ferrule that is used to measure wire rod exposes the measurement tool of size.

[background technology]

When prior art exposes size in the ferrule of measuring USB line, HDMI line wire rods such as (HDMI (High Definition Multimedia Interface) lines), often use vernier caliper to measure, but measure the surface of contact disunity like this, the size out of true; And when measuring, still need gauge block measurement, and measure out of true, and when measuring, be easy to damage product, make non-defective unit become defective products, cost of idleness; Use vernier caliper measurement efficient not high, the detection that is not suitable for wire rod in enormous quantities is measured.

In view of this, be necessary to develop a kind of measurement tool in fact, when this measurement tool exposed size in the ferrule of measuring wire rod, measurement size was accurately reliable, and surface of contact is unified, and efficiency of measurement is than higher.

[summary of the invention]

Therefore, the purpose of this utility model provides a kind of measurement tool, and when this measurement tool exposed size in the ferrule of measuring wire rod, measurement size was accurately reliable, and surface of contact is unified, and efficiency of measurement is than higher.

In order to achieve the above object, measurement tool of the present utility model, its ferrule that is used to measure wire rod exposes size, and this measurement tool comprises:

Base plate which is provided with first holding tank and second holding tank;

Dial gauge, it is located in above-mentioned first holding tank, and this dial gauge comprises sleeve, measuring staff, dial plate, reaches inner drive mechanism, and this measuring staff moves in this sleeve, and this dial plate is provided with pointer and scale;

Contact block, it is located in above-mentioned second holding tank and with base plate and is connected, this contact block is provided with groove and wears wherein for the ferrule that an end and the wire rod of above-mentioned measuring staff exposes, and the ferrule that above-mentioned measuring staff and this wire rod expose during measurement is vertical and on same measurement face.

Especially, above-mentioned contact block is connected with base plate by two-screw.

Especially, the material of above-mentioned contact block is the steel material.

Especially, above-mentioned dial gauge is the mechanical type dial gauge.

Compared to prior art, when measurement tool of the present utility model exposes size in the ferrule of measuring wire rod, measure by using dial gauge, measurement size is accurately reliable, and wear wherein by the ferrule of using contact block that wire rod is exposed, surface of contact is unified, and efficiency of measurement is higher.

[embodiment]

Please consult Fig. 1, shown in Figure 2 simultaneously, it illustrates the decomposing schematic representation that the utility model is measured the combination synoptic diagram of tool, the utility model measurement tool respectively.

Measurement tool of the present utility model, its ferrule 410 that is used to measure wire rod 400 exposes size, and in present embodiment, this measurement tool comprises:

Base plate 100 which is provided with first holding tank 110 and second holding tank 120;

Dial gauge 200, this dial gauge 200 is the mechanical type dial gauge, this dial gauge 200 is located in above-mentioned first holding tank 110, this dial gauge 200 comprises sleeve 223, measuring staff 210, dial plate 220, reaches inner gear train, this inner drive mechanism is a gear, this dial plate 220 is provided with pointer 221 and scale 222, and above-mentioned measuring staff 210 moves in above-mentioned sleeve 223, and this pointer 221 comprises big pointer 2211 and little finger of toe pin 2212;

Contact block 300, the material of this contact block 300 is the steel material, fastness to rubbing is good, utilize the time long, this contact block 300 is located in above-mentioned second holding tank 120 and by use two-screw 320 and is connected with above-mentioned base plate 100, this contact block 300 is provided with groove 310 and wears wherein for the ferrule 410 that an end and the wire rod 400 of above-mentioned measuring staff 210 exposes, and above-mentioned measuring staff 210 and this wire rod 400 expose during measurement ferrule 410 is vertical and on same measurement face.

See also shown in Figure 3ly, it illustrates the working state schematic representation that the utility model is measured tool.When the ferrule 410 of measuring wire rod 400 exposes size, at first check the dirigibility of measuring staff 210 activities, promptly promote to measure bar 210 gently, without any bundle card phenomenon, and after loosening measuring staff 210, pointer 221 can return to original position at every turn; And adjust dial gauge 200, make pointer 221 zero sets of dial gauge 200; The ferrule 410 that wire rod 400 is exposed contacts gently with the measuring staff 210 of dial gauge 200 then, and the ferrule 410 that will expose moves for 310 li to groove, the ferrule 410 that exposes until wire rod 400 all enters into the groove 310 of contact block 300, the measuring staff 210 that promotes dial gauge 200 when the ferrule 410 that wire rod 400 exposes moves moves in sleeve 223, measuring staff 210 straight-line displacements that ferrule 410 sizes that tested then wire rod 400 exposes cause are amplified through the drive mechanism transmission of dial gauge 200 inside, become the rotation of pointer 221 on the dial plate 220, according to the scale 222 that rotates, it is 0.01 millimeter that the big pointer 2211 of this pointer 221 is whenever walked a lattice scale, it is 1 millimeter that little finger of toe pin 2212 is whenever walked a lattice scale, thus the size of reading measured size.
