Abstract
Provided is an inner hole measuring tool. Two same support plates are both strip-shaped plates, the back ends of the support plates are connected with two circular pinch plates in a welded mode, and the pinch plates are overlapped up and down and connected together through a pin penetrating the middles of the pinch plates; the front ends of the support plates are each provided with a top head outwards stretching; the middle of one side of each support plate is connected with a strip-shaped support seat in a welded mode, a bolt penetrates one end of one support seat to be connected with the other support seat in a welded mode, a spring arranged on the bolt in a sleeving mode is arranged between the support seats, and one end of the bolt is provided with a limit nut matched with the bolt. Compared with the prior art, the inner hole measuring tool has the advantages of being simple in structure and technology, convenient to manufacture and install, low in cost and good in effect and like.
Description
technical field
The present invention relates to a kind of mechanical measurement instrument, particularly relate to a kind of hole measuring instrument.
background technology
In field of machining, during processing axle sleeve, hole size is greater than outside dimensions, and existing hole measuring instrument cannot realize Measurement accuracy, and along with improving constantly of machining level, existing survey instrument can not meet the user demand of people; A lot of design has been there is about hole measuring, but most complex structure, complex operation, expensive, so provide a kind of structure simple, the hole measuring instrument of simple operation is very necessary.
summary of the invention
For solving above deficiency, the object of the present invention is to provide a kind of hole measuring instrument, this hole measuring instrument is measured accurately, measures efficiency high, simple to operate, with low cost, long service life.
The present invention mainly takes, and concrete scheme is as follows:
The present invention mainly includes support plate, buckle, pin, top, bearing, spring, bolt and stop nut, wherein two identical support plates are stripe board, the rear end of support plate all welds together with circular buckle, two buckles coincide with the upper and lower setting, and they are by linking together through the pin in the middle part of it; The front end of above-mentioned support plate establishes the top of stretching out toward the outer side respectively, these two the corresponding settings in top; One middle side part of described two support plates all welds the bearing of bar shaped, has a bolt, and it welds together through a bearing one end and another bearing, and be provided with a spring be enclosed within bolt between described two, the two ends of this spring connect with bearing respectively; The stop nut matched with it is established in one end of above-mentioned bolt.
The present invention, in the process of practical application, stretches in inner hole of shaft sleeve after being shunk by two support plates, unclamps support plate, then clamp nut is locked, again shrink two support plates to take out by axle sleeve, after unclamping, two support plates are reset to clamp nut latched position, now can measure the size of endoporus.
The present invention compared with prior art tool has the following advantages:
1, measure accurately, measure efficiency high, simple to operate, with low cost, long service life.
accompanying drawing explanation
Fig. 1 is perspective view of the present invention.
Number in the figure: 1-support plate; 2-buckle; 3-pin; 4-bearing; 5-bearing; 6-bolt; 7-spring; 8-nut.
embodiment
In the schematic diagram of the present invention shown in Fig. 1, two identical support plates 1 are stripe board, and the rear end of support plate all welds together with circular buckle 2, and two buckles coincide with the upper and lower setting, and they are by linking together through the pin 3 in the middle part of it; The front end of above-mentioned support plate establishes the top 4 of stretching out toward the outer side respectively, these two the corresponding settings in top; One middle side part of described two support plates all welds the bearing 5 of bar shaped, has a bolt 6, and it welds together through a bearing one end and another bearing, and be provided with a spring 7 be enclosed within bolt between described two, the two ends of spring connect with bearing respectively; The stop nut 8 matched with it is established in one end of above-mentioned bolt.
