Abstract

The utility model discloses a contact thickness gauge which comprises a base, a support element vertically stood on the rear end of the base, and a hanging arm transversely connected on the support element, wherein a dial indicator is threaded through the hanging arm, and the area of the lower end surface of a measuring rod on the lower end of the dial indicator is smaller than or equal to 1mm2. A contact positioning board is arranged on the base, and is located on the lower portion of the measuring rod, and at least one contact positioning hole which is matched with contacts with different specifications is arranged on the contact positioning plate. Compared with the prior art, as the area of the lower end surface of the measuring rod is extremely small, the thickness on each partial position of the contact can be accurately measured, and the overall condition of the contact thickness can be reflected by measuring a plurality of points on the contact, and a to-be-measured contact can be easily placed in the matching positioning hole, the use is simple and convenient, the positioning is accurate and fast, the placement is stable and reliable, and the efficiency of detection is greatly improved.

Description

A kind of contact thicknessmeter

Technical field

The utility model relates to a kind of surveying instrument, particularly a kind of contact thicknessmeter.

Background technology

Along with development of electronic technology, the application of contact more and more widely, quality requirements for the contact is also more and more higher, therefore, after the contact production and processing is finished, need do in detail and accurate the detection the quality of contact, wherein, thickness of contact is an important test item, in the prior art, usually use milscale or dial gauge to measure, but milscale exists use inconvenient, and reading is slower, the shortcoming of inefficiency, though the use of dial gauge will make things convenient for than milscale, reading is also more rapid, and still, milscale and dial gauge are when measuring, the parts and the contact area of object under test of getting a little are all bigger, particularly less with respect to this area in contact own object is all the more so, so just has a problem, the resulting result data of thickness of contact maximum often after milscale and dial gauge are measured, therefore, the accuracy meeting of measurement result is had a greatly reduced quality.In addition, use dial gauge to measure, need the contact steadily to place, but, be not easy to the location, be not easy steady placement because the contact volume is less, and, the situation about measuring of being unfavorable for such as when measuring, be moved, topple over easily, greatly reduce the efficient of detection.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of simple and reasonable, easy to use, and the detection efficiency height is measured contact thicknessmeter accurately.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of contact thicknessmeter, comprise base, be erected in the support member of base rear end, be laterally connected in the suspension arm on the support member, be equipped with dial gauge on the suspension arm, the area of the lower surface of the sounding rod of dial gauge lower end is less than or equal to 1mm ²

In order to obtain better technique effect, further technical measures also comprise:

Above-mentioned base is provided with the contact location-plate, and the contact location-plate is positioned at the below of sounding rod, offers the suitable contact pilot hole in contact of at least one and all size on the location-plate of contact.

Offer chute on the axis direction of above-mentioned support member, the tail end of suspension arm passes and slides from the front side of chute and is inserted in the chute, the tail end of the suspension arm fixed bolt that has been threaded, the trailing flank of fixed bolt apical grafting support member.

The upper end of above-mentioned support member has the hole that links with chute, the support member height adjusting screw rod that has been threaded through the hole, the fixedly connected suspension arm in the lower end of height adjusting screw rod also is arranged with spring on the height adjusting screw rod, the lower end apical grafting suspension arm of spring, the upper side of upper end apical grafting chute.

The upper end of above-mentioned height adjusting screw rod also is equipped with control hand wheel.

Compared with prior art, the utility model comprises base, be erected in the support member of base rear end, be laterally connected in the suspension arm on the support member, be equipped with dial gauge on the suspension arm, the area of the lower surface of the sounding rod of dial gauge lower end is less than or equal to 1mm, because the area of the lower surface of sounding rod is very little, therefore can accurately measure the thickness of each local location on the contact, get several points more and measure the overall condition that can accurate response goes out contact thickness; And, the utility model base is provided with the contact location-plate, the contact location-plate is positioned at the below of sounding rod, offer the suitable contact pilot hole in contact of at least one and all size on the location-plate of contact, therefore, contact to be measured can be positioned in the pilot hole suitable with it easily, easy to use, and accurate positioning is quick, puts reliable and stablely, has improved the efficient that detects greatly.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment as shown in Figure 1 to Figure 3, figure grade explanation: base 1, support member 2, chute 2a, hole 2b, suspension arm 3, dial gauge 4, sounding rod 4a, contact location-plate 5, contact pilot hole 5a, fixed bolt 6, height adjusting screw rod 7, spring 8, control hand wheel 9.

As shown in the figure, a kind of contact thicknessmeter comprises base 1, is erected in the support member 2 of base 1 rear end, is laterally connected in the suspension arm 3 on the support member 2, is equipped with dial gauge 4 on the suspension arm 3, and the area of the lower surface of the sounding rod 4a of dial gauge 4 lower ends is less than or equal to 1mm ², base 1 is provided with contact location-plate 5, and contact location-plate 5 is positioned at the below of sounding rod 4a, offers the suitable contact pilot hole 5a in contact of at least one and all size on the contact location-plate 5.Because the area of the lower surface of sounding rod is very little, therefore can accurately measure the thickness of each local location on the contact, get several points more and measure the overall condition that can accurate response goes out contact thickness; And contact to be measured can be positioned in the pilot hole suitable with it easily, and is easy to use, and accurate positioning is quick, puts reliable and stablely, improved the efficient that detects greatly.
