Description

Technical Field

[0001] This utility model relates to the field of mechanical parts measurement, specifically to a precision measuring device for machining mechanical parts. Background Technology

[0002] Mechanical parts, also known as mechanical components, are the basic building blocks of machinery; they are inseparable individual parts that make up machines. Before being assembled and used, mechanical parts require a series of processing steps. For parts such as shafts, keys, and rings, dimensions are one of the important requirements for measuring whether the parts are qualified and are key to ensuring the quality of the parts. Currently, after the parts are machined, they are mainly measured manually using measuring tools such as rulers, vernier calipers, and protractors.

[0003] However, the aforementioned measuring tools have relatively limited functions. For example, vernier calipers are mainly used to measure the inner and outer diameters of parts (diameter dimensions), and protractors can only measure angles (angle dimensions). When measuring the dimensions of parts, personnel need to carry many measuring tools, which is inconvenient. Therefore, a precision measuring device for machining mechanical parts is provided.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] This application provides a precision measuring device for machining mechanical parts, mainly to solve the problem that personnel need to carry many measuring tools when measuring the dimensions of parts, which is inconvenient. The following technical solution is provided and will be described in detail below: Example

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the crossbar 1 includes a groove in the middle of the crossbar 1, within which a scale 2 is fixedly installed. An upper fixed head 3 is fixedly installed at the top of one end of the crossbar 1. An inner diameter measuring mechanism 4 for measuring the inner diameter of mechanical parts is slidably disposed on the side of the upper fixed head 3. A lower fixed head 5 is fixedly installed at the bottom of one end of the crossbar 1. An outer diameter measuring mechanism 6 for measuring the outer diameter of mechanical parts is slidably disposed on the side of the lower fixed head 5. A cross plate 7 is fixedly fixed to the side of the crossbar 1. A vertical plate 8 is rotatably connected to the end of the cross plate 7 near the crossbar 1. An angle measuring mechanism 9 is disposed between the vertical plate 8 and the cross plate 7. The inner diameter measuring mechanism 4 includes an inner diameter measuring mechanism opposite to the upper fixed head 3. The inner diameter measuring clamp 401 has an upper slider 402 fixedly installed at its end. The upper slider 402 slides on the top surface of the crossbar 1 and is threadedly connected to the top surface of the upper slider 402. The end of the upper bolt 403 acts on the top surface of the crossbar 1. The outer diameter measuring mechanism 6 includes an outer diameter measuring clamp 601 opposite to the lower fixed head 5. The outer diameter measuring clamp 601 has a lower slider 602 fixedly installed at its end. The lower slider 602 slides in the middle of the crossbar 1 and is threadedly connected to the top surface of the lower slider 602. The end of the lower bolt 603 acts on the bottom surface of the crossbar 1. The scales on the uniform scale 2 of the inner diameter measuring clamp 401 and the outer diameter measuring clamp 601 are flush.

[0021] Specifically: Through the inner diameter measuring mechanism 4 and the outer diameter measuring mechanism 6, the device can simultaneously measure the inner and outer diameters of mechanical parts, meeting various measurement needs. The combined design of the horizontal plate 7 and the vertical plate 8, combined with the angle measuring mechanism 9, can measure the angles of mechanical parts. This device is suitable for measuring a variety of mechanical parts and can meet the needs of different processing scenarios.

[0022] The working principle here is as follows: The inner diameter measuring mechanism 4 includes an inner diameter measuring clamp 401 and an upper slider 402. The inner diameter measuring clamp 401 is opposite to the upper fixed head 3 and is used to clamp and measure the inner diameter of mechanical parts. The upper slider 402 is fixedly installed at the end of the inner diameter measuring clamp 401. The upper slider 402 slides on the top surface of the crossbar 1. By sliding the upper slider 402, the position of the inner diameter measuring clamp 401 can be adjusted to adapt to the inner diameter measurement needs of different sizes. An upper bolt 403 is threadedly connected to the top surface of the upper slider 402. By tightening the upper bolt 402... Bolt 403 can fix the upper slider 402 at a specific position on the top surface of the crossbar 1, thereby ensuring the fixed position of the inner diameter measuring clamp 401 and guaranteeing the accuracy of the measurement. The inner diameter measuring clamp 401 is inserted into the inner hole of the mechanical part, and the position of the inner diameter measuring clamp 401 is adjusted by sliding the upper slider 402 to make it contact the inner hole wall. After tightening the upper bolt 403 to fix the position, the position of the inner diameter measuring clamp 401 is read by the scale 2, thereby obtaining the inner diameter dimension. The outer diameter measuring mechanism 6 includes an outer diameter measuring clamp 601 and a lower slider 602. The outer diameter measuring clamp 601 is opposite to the lower fixed head 5 and is used to clamp and measure the outer diameter of mechanical parts. A lower slider 602 is fixedly installed at the end of the outer diameter measuring clamp 601. The lower slider 602 slides in the middle of the crossbar 1. By sliding the lower slider 602, the position of the outer diameter measuring clamp 601 can be adjusted to adapt to the outer diameter measurement needs of different sizes. A lower bolt 603 is threaded on the top surface of the lower slider 602. By tightening the lower bolt 603, the lower slider 602 can be fixed at a specific position on the bottom surface of the crossbar 1, thereby ensuring the outer diameter measurement. The position of the outer diameter measuring clamp 601 is fixed to ensure the accuracy of the measurement. The outer diameter measuring clamp 601 is placed on the outer surface of the mechanical part. The position of the outer diameter measuring clamp 601 is adjusted by sliding the lower slider 602 so that it contacts the outer surface. After tightening the lower bolt 603 to fix the position, the position of the outer diameter measuring clamp 601 is read by the scale 2 to obtain the outer diameter dimension. The angle measuring mechanism 9 is set between the horizontal plate 7 and the vertical plate 8. The horizontal plate 7 is fixed to the side of the horizontal bar 1, and the vertical plate 8 is rotatably connected to the horizontal plate 7. It is used to measure the angle of the mechanical part. Example

[0023] The solution in Example 1 will be further described below with reference to its specific working method.

[0024] like Figure 1 and Figure 4As shown, in some embodiments, the angle measuring mechanism 9 includes a measuring plate 901 fixed to the side of the vertical plate 8. A groove 902 is provided on the measuring plate 901. The end of the measuring plate 901 away from the vertical plate 8 slides on the horizontal plate 7. A locking bolt 903 is threaded into the groove 902, and its end acts on the horizontal plate 7. An angle measuring scale 904 is marked on the measuring plate 901. The working principle here is as follows: when it is necessary to measure the angle of a mechanical part, first loosen the locking bolt 903, and then manually rotate the vertical plate 8 to adjust the angle between the vertical plate 8 and the horizontal plate 7. Align the vertical plate 8 with the angle of the mechanical part to be measured. After adjusting to a suitable angle, tighten the locking bolt 903 to fix the measuring plate 901 on the horizontal plate 7, ensuring that the angle between the vertical plate 8 and the horizontal plate 7 no longer changes. Read the angle value between the vertical plate 8 and the horizontal plate 7 through the angle measurement scale 904 on the measuring plate 901. The scale can be a mechanical scale or the display value of an electronic angle sensor. The end of the measuring plate 901 away from the vertical plate 8 can slide on the horizontal plate 7, which allows the measuring plate 901 to adapt to different measurement positions and angle requirements.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
