Description

Technical Field

[0001] The utility model belongs to the technical field of dimension measurement, and in particular relates to a ruler for measuring a rough machining process. Background Art

[0002] The sawing operation in the mechanical processing plant has poor working conditions, serious emulsion and oil pollution, and mainly saws steel. When rough processing sawing operations are required, the operator will visually or roughly measure the approximate size of the sample after receiving it to see if it can meet the requirements of the commissioned sample. Before sawing, the size of the sawed sample will be measured with a ruler, and the size of the sample will be confirmed again after sawing to see if it meets the requirements. If the sample size is too large, it will continue to saw. If the sample size is too small, it will be scrapped and re-cut. The qualified sample will be sent to the finishing position for processing. The rulers commonly used for rough processing sawing machines now include vernier calipers, steel tape measures, plastic rulers, steel plate rulers, etc. Each rough processing sawing machine operation position will choose its own relatively suitable measuring tools according to its own working environment, cutting sample size and other factors.

[0003] In rough processing and sawing operations, the frequency of using rulers for measurement is quite high, and durability and convenience are more important, and the requirements for precision are not very high. Vernier calipers are tools used in fine processing positions, which are a bit "overkill" for rough processing positions. In addition, for vernier calipers with large measuring ranges, the rulers are relatively heavy and inflexible to operate, and are generally not suitable for use on rough processing sawing machines; steel tape measures and plastic rulers are relatively convenient to use, but they are easy to damage, and frequent replacement affects work and wastes costs; at this stage, the most commonly used is the steel plate ruler, which is not easy to damage, but the size scale on the steel ruler is easy to wear. After a period of use, the scale is worn and cannot be read correctly, so a new ruler can only be replaced. Therefore, in order to improve work efficiency and reduce the consumption of rulers, a special measuring ruler that is easy to use, durable, and not easy to damage is urgently needed. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a ruler for measuring a rough machining process which is easy to use, low-cost and has good scale wear resistance.

[0005] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0006] A ruler for measuring in a rough machining process, comprising a ruler body, the ruler body being in the shape of a long plate, with ruler ends being left near the two end surfaces of the ruler body, and the length of the ruler ends at the two ends being 5 mm; a row of scale grooves is evenly distributed along the ruler length direction at a position between the two ruler ends on the ruler body, each scale groove is a through groove connecting the upper and lower surfaces of the ruler body, and the distance between adjacent scale grooves is 1 mm; the scale grooves include short scale grooves, middle scale grooves and long scale grooves; the starting scale grooves at both ends are middle scale grooves, and a middle scale groove is provided at intervals of 10 mm, the scale groove in the middle position between two adjacent middle scale grooves is a long scale groove, and the scale grooves between each long scale groove and the middle scale grooves on both sides are short scale grooves;

[0007] Taking one end of the ruler as the measurement starting point, the short scale groove corresponds to the dimension value of multiples of 1mm, the middle scale groove corresponds to the dimension value of odd multiples of 5mm, and the long scale groove corresponds to the dimension value of even multiples of 5mm;

[0008] The length of the ruler is an integral multiple of 100 mm, and the left and right sides of the ruler are symmetrical.

[0009] Moreover, the ruler material is stainless steel.

[0010] Moreover, a first identification hole is connected to the inner end of a length scale groove of an odd multiple of 50 mm on the ruler body, and a second identification hole is connected to the inner end of a length scale groove of an even multiple of 50 mm, and the apertures of the first identification hole and the second identification hole are different.

[0011] Moreover, the first identification hole is a small hole, and the second identification hole is a large hole.

[0012] The advantages and positive effects of the utility model are:

[0013] 1. Compared with the traditional steel ruler reading scale method, the utility model uses the scale groove and hole to indicate the scale on the ruler body, which avoids the scale wear. The ruler ends with 5mm unprocessed scale grooves at both ends of the ruler are not easy to be bumped and bent, and are strong and durable.

[0014] 2. The length of the ruler of the utility model is an integral multiple of 100 mm. The left and right sides of the ruler are completely symmetrical, and readings can be made on both sides. Both sides can also be used, which has the advantages of convenient and flexible operation and easy use.

[0015] 3. The utility model uses scale grooves of different lengths and further combines two sizes of identification holes to identify the scale values, which has the advantages of convenient reading and flexible operation. BRIEF DESCRIPTION OF THE DRAWINGS
