Fig. 1 is a schematic perspective view of a long axis length dimension inspection device according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.
The specific structure of the long axis length dimension detection tool provided by the embodiment comprises a base plate 1 and a guide rail 2 arranged on the base plate 1, wherein a small limiting block 3 with an adjustable position and a plurality of threaded holes are further arranged on the base plate, as shown in fig. 1.
The guide rail 2 is sequentially provided with a V-shaped limiting block 4, a first V-shaped supporting block 5, a second V-shaped supporting block 6 and a gauge stand 7, the gauge stand 7 is provided with a digital display dial indicator 8, and the front end of the digital display dial indicator 8 is provided with a telescopic probe 9; in addition, the first V-shaped supporting block 5, the second V-shaped supporting block 6 and the gauge stand 7 on the guide rail 2 are connected with the guide rail 2 through the sliding block 10, so that the positions of the guide rail 2 can be conveniently adjusted in a back-and-forth sliding mode.
The V-shaped limiting block 4 is arranged at one end of the guide rail 2 and is screwed and fixed with the threaded hole on the bottom plate 1 through a screw; the small limiting block 3 on the bottom plate 1 is positioned between the second V-shaped supporting block 6 and the gauge stand 7, the small limiting block 3 is screwed and fixed with a threaded hole on the bottom plate 1 through a screw, but the position of the small limiting block 3 can be adjusted on the bottom plate 1 according to measurement requirements and then fixed.
The specific working principle of the long axis length gauge provided by this embodiment is as follows, during measurement, a standard long axis and a long axis to be measured are provided, the standard long axis is firstly placed on the first V-shaped supporting block 5 and the second V-shaped supporting block 6, the placed standard long axis and the two V-shaped supporting blocks slide towards the direction of the V-shaped limiting block 4 until the long axis abuts against the V-shaped limiting block 4, at this time, according to the length of the standard long axis, the position of the small limiting block 3 is determined at the tail end of the standard long axis and is fixed on the bottom plate 1, after the fixation is completed, the gauge stand 7 slides towards the small limiting block 3 and the gauge stand 7 abuts against the small limiting block 3, at this time, the telescopic probe 9 at the front end of the digital display dial gauge 8 contacts the end face of the standard long axis, and a certain amount of compression is generated due to extrusion, the amount of compression at this time is defined as the, and the display value on the digital display dial indicator 8 is set as 0.00, which is used as a fixed reference for measurement.
