Description

Technical Field

[0001] This utility model relates to the field of precision mechanical parts testing technology, specifically a simple device for testing the thickness of precision mechanical parts. Background Technology

[0002] Calipers are a commonly used tool in simple thickness measurement devices for precision mechanical parts. Due to their simple structure and convenient operation, they are widely used in the thickness measurement of various regularly shaped parts, enabling quick and relatively accurate acquisition of thickness data.

[0003] However, in actual testing, there are often requirements to inspect irregularly shaped parts, such as curved blocks, which resemble the shape of a kettle lid. When it is necessary to measure the thickness of the inner top of the curved block, the measuring jaws of the calipers are easily jammed by the bottom of the curved block when it is inserted into the interior, making it impossible to reach the inner top smoothly for measurement, which presents a limitation.

[0004] The reason for this problem is that, on the one hand, the length and shape of the measuring jaws of traditional calipers are fixed, making it difficult to adapt to the complex internal structure of irregularly shaped parts. When facing the arc-shaped contour at the bottom of an arc-shaped block, the measuring jaws cannot avoid obstacles and accurately contact the inner top. On the other hand, the internal space of the arc-shaped block is limited and its shape is irregular. After the measuring jaws of the calipers are inserted, it is difficult to maintain a stable measurement posture, which causes the measurement reference to shift, thus making it impossible to obtain accurate thickness data, which has limitations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a simple device for detecting the thickness of precision mechanical parts. It solves the problem that when the measuring jaws of calipers are inserted into the arc-shaped block, they are easily jammed by the bottom of the block, preventing them from reaching the top for measurement and thus limiting their effectiveness.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a simple device for detecting the thickness of precision mechanical parts, including a caliper, wherein an inner wall measuring unit is provided on one side of the caliper, and the inner wall measuring unit includes a sleeve block, a flip column and a threaded column;

[0013] Preferably, a connecting block is fixedly mounted at the bottom of the flipping column, a rough surface is fixedly mounted on one side of the connecting block, and a hook surface is fixedly mounted on one side of the positioning block, with the rough surface and the hook surface closely fitting together.

[0014] Preferably, the connecting block is provided with rotating shafts on both sides, and the rotating shafts are rotatably connected to the fixed block.

[0015] Preferably, a torsion spring is sleeved on the outer surface of the rotating shaft. One end of the torsion spring is fixedly assembled to the rotating shaft, and the other end of the torsion spring is fixedly assembled to the fixing block. The torsion spring is used to ensure that the flipping column is in a horizontal position.

[0016] Preferably, the inside of the flip column is provided with a slot, and the bottom of the threaded column is fixedly equipped with an anti-detachment block, which abuts against the inner wall of the slot.

The threaded column is threadedly engaged with the rotating column, and rotating the threaded column changes its length extending beyond the rotating column, allowing it to contact the inner top of irregularly shaped parts such as arc-shaped blocks, thus achieving accurate measurement of their thickness.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a simple device for detecting the thickness of precision mechanical parts, according to the attached... Figure 1-2 As shown, it includes a caliper 1, and an inner wall measuring unit 2 is provided on one side of the caliper 1. The inner wall measuring unit 2 includes a sleeve block 21, a flip post 22 and a threaded post 23.

[0028] The sleeve 21 is movably engaged on one side of the caliper 1; the flip post 22 is rotatably connected to the sleeve 21; the threaded post 23 is rotatably connected inside the flip post 22, and the threaded post 23 is threadedly engaged with the flip post 22.

[0029] The caliper 1 includes a body 11, an upper outer measuring jaw 12 and a lower outer measuring jaw 13; the upper outer measuring jaw 12 is fixedly mounted on the top of the body 11; a slider is slidably connected to the body 11, the lower outer measuring jaw 13 is fixedly mounted on one side of the slider, and a sleeve block 21 is sleeved on the lower outer measuring jaw 13.

[0030] In this embodiment, the ruler body 11 serves as the basic component, with the upper outer measuring jaw 12 fixed to the top of the ruler body 11 and the lower outer measuring jaw 13 slidably connected to the ruler body 11 via a slider. When measuring the thickness of a part, pushing the slider moves the lower outer measuring jaw 13, causing the upper outer measuring jaw 12 and the lower outer measuring jaw 13 to contact the two sides of the part respectively. At this time, the thickness value of the part can be read through the scale on the ruler body 11 and the corresponding position of the slider.

[0031] According to the appendix Figure 1 , 3 As shown in Figure 4, further, it includes a caliper 1, and an inner wall measuring unit 2 is provided on one side of the caliper 1. The inner wall measuring unit 2 includes a sleeve block 21, a flip post 22 and a threaded post 23.

[0032] The sleeve 21 is movably engaged on one side of the caliper 1; the flip post 22 is rotatably connected to the sleeve 21; the threaded post 23 is rotatably connected inside the flip post 22, and the threaded post 23 is threadedly engaged with the flip post 22.

[0033] Bolts 24 are installed inside the sleeve block 21, and bolts 24 are threadedly engaged with the lower outer measuring jaw 13. A locking block 25 is provided on one side of the sleeve block 21, and the flipping column 22 is movably locked inside the locking block 25. A positioning block 26 is provided on one side of the locking block 25, and fixing blocks 27 are provided at both ends of the positioning block 26. The fixing blocks 27 are fixedly assembled with the sleeve block 21. A connecting block 28 is fixedly assembled at the bottom of the flipping column 22. A rough surface 29 is fixedly assembled on one side of the connecting block 28, and a hook surface 210 is fixedly assembled on one side of the positioning block 26. The rough surface 29 and the hook surface 210 fit tightly together. Rotating shafts 211 are provided on both sides of the connecting block 28, and the rotating shafts 211 are rotatably connected to the fixing blocks 27. A torsion spring 212 is sleeved on the outer surface of the rotating shaft 211. One end of the torsion spring 212 is fixedly assembled with the rotating shaft 211, and the other end of the torsion spring 212 is fixedly assembled with the fixing block 27. The torsion spring 212 is used to ensure that the flipping column 22 is in a horizontal position. The inside of the flip column 22 is provided with a slot 213, and the bottom of the threaded column 23 is fixedly equipped with an anti-detachment block 214, which abuts against the inner wall of the slot 213.

[0034] In this embodiment, the threaded post 23 is adjustable because different irregularly shaped parts have different internal structures and dimensions. By rotating the threaded post 23 to change its length extending beyond the flip post 22, it can adapt to measurement needs at different depths and positions, ensuring accurate contact with the inner top of the irregularly shaped part. The torsion spring 212 drives the rotating shaft 211 to rotate through its own torque when no external force is applied, thereby ensuring that the flip post 22 is in a horizontal position and preventing it from swaying and affecting normal measurement or storage. The rough surface 29 and the hook surface 210 have a strong adhesive force. When the flip post 22 rotates to a certain angle, the friction generated by the tight fit between the rough surface 29 and the hook surface 210 can resist the torque of the torsion spring 212, keeping the flip post 22 stably at that angle.

[0035] Working principle: Place the sleeve 21 onto the lower outer measuring jaw 13 and tighten the bolt 24 to secure the sleeve 21. Next, rotate the flipping column 22 to overcome the torque of the torsion spring 212 and rotate it from a horizontal position. At this time, the rough surface 29 and the hook surface 210 are tightly fitted, securing the flipping column 22. Rotate the threaded column 23 to reach the desired length. Then, insert the upper outer measuring jaw 12 and the lower outer measuring jaw 13 of the caliper 1 into the irregular part, simultaneously allowing the upper outer measuring jaw 12 and the threaded column 23 to contact the top and inner top of the irregular part, respectively. Finally, read the scale value corresponding to the slider on the caliper body 11 to obtain the first measurement. Then, remove the caliper 1, and place the threaded column 23 against the upper outer measuring jaw 12 to obtain the second measurement. Subtract the second measurement from the first measurement to obtain the thickness of the inner top of the irregular part. After the measurement is completed, rotate the flip column 22 in the opposite direction. Under the action of the torsion spring 212, it will return to the horizontal position. Loosen the bolt 24 and remove the sleeve 21. At this time, other materials can be measured.
