Abstract
The utility model discloses an adjustable edge of a knife chi, its characterized in that: the first knife edge ruler and the second knife edge ruler are reversely superposed, a guide groove is formed in the first knife edge ruler, two positioning blocks are arranged on the second knife edge ruler at intervals and are arranged in the guide groove in a sliding fit mode, the measuring edges of the first knife edge ruler and the second knife edge ruler are located on the same plane, and a locking device for limiting the relative sliding of the first knife edge ruler and the second knife edge ruler is further arranged on the second knife edge ruler. The beneficial effects of the utility model include: the application range of the knife edge ruler is increased, the acquisition cost of the measuring tool is reduced, and the detection efficiency is improved.
Description
Technical Field
The utility model relates to a measuring tool field, concretely relates to adjustable edge of a knife chi.
Background
The knife edge ruler is mainly used for measuring straightness and flatness by an optical gap method, and can also be used for detecting plane precision together with a measuring block. The measuring tool has the advantages of simple structure, light weight, no rustiness, convenient operation, high measuring efficiency and the like, and is a common measuring tool for machining.
The existing knife edge ruler is of a fixed specification, so that knife edge rulers of various specifications are required to be equipped according to the size of a product to be detected, the cost of a detection tool is increased, and the knife edge ruler with a wider application range is required to be designed under the condition that the size of the product is changeable.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides an adjustable edge of a knife chi, its simple structure makes lowly, and application scope is wide.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an adjustable knife edge ruler is characterized in that: the first knife edge ruler and the second knife edge ruler are reversely superposed, a guide groove is formed in the first knife edge ruler, two positioning blocks are arranged on the second knife edge ruler at intervals and are arranged in the guide groove in a sliding fit mode, the measuring edges of the first knife edge ruler and the second knife edge ruler are located on the same plane, and a locking device for limiting the relative sliding of the first knife edge ruler and the second knife edge ruler is further arranged on the second knife edge ruler.
Further, the guide groove is a waist-shaped groove milled on the first blade scale.
Furthermore, the positioning block is a sliding block protruding outwards from the second knife edge ruler, the thickness of the sliding block is smaller than that of the first knife edge ruler, and the upper surface and the lower surface of the sliding block are precisely matched with the inner side wall of the guide groove.
Furthermore, the locking device is a locking screw, the locking screw is a pan head screw, screw holes matched with the locking screw are formed in the two positioning blocks, the threaded end of the locking screw penetrates through the guide groove and then is connected with the positioning blocks, and the diameter of the pan head of the locking screw is larger than the width of the guide groove.
The beneficial effects of the utility model include: the application range of the knife edge ruler is increased, the acquisition cost of the measuring tool is reduced, and the detection efficiency is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
An adjustable cutting edge ruler as shown in fig. 1 comprises a first cutting edge ruler 1 and a second cutting edge ruler 2, wherein the first cutting edge ruler 1 and the second cutting edge ruler 2 are reversely overlapped, a guide groove 3 is formed in the first cutting edge ruler 1, and the guide groove 3 is a waist-shaped groove milled in the first cutting edge ruler 1. The second knife edge rule 2 is provided with two positioning blocks 4 which are arranged at intervals, the positioning blocks 4 are sliding blocks which protrude outwards on the second knife edge rule 2, and the thickness of the sliding blocks is smaller than that of the first knife edge rule 1. The two positioning blocks 4 are arranged in the guide groove 3 in a sliding fit manner, the measuring edges of the first knife edge ruler 1 and the second knife edge ruler 2 are located on the same plane, the upper surface and the lower surface of the sliding block are precisely matched with the inner side wall of the guide groove 3 and can slide relatively, and the overall measuring length of the knife edge ruler is changed through relative sliding.
The second knife edge ruler 2 is also provided with a locking device 5 for limiting the relative sliding of the first knife edge ruler 1 and the second knife edge ruler 2. After the first cutting edge rule 1 and the second cutting edge rule 2 relatively slide to a required length, a locking device 5 can be screwed to lock the measurement length of the cutting edge rule, in this embodiment, the locking device 5 is a locking screw, the locking screw is a pan head screw, screw holes matched with the locking screw are arranged on the two positioning blocks 4, a threaded end of the locking screw passes through the guide groove 3 and then is connected with the positioning blocks 4, and the pan head diameter of the locking screw is larger than the width of the guide groove 3.
From this the utility model discloses an adjustable edge of a knife chi both can detect the less product of size, also can detect the great product of size, has saved the cost of purchasing multiple specification edge of a knife chi.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
