[0002] Currently, the demand for measuring the internal dimensions of bushing-type workpieces is increasing in the manufacturing industry. High-precision internal diameter measurement is crucial during parts assembly. A wide variety of measuring tools are available on the market, such as vernier calipers, micrometers, and optical micrometers. Existing measurement methods mainly fall into two categories: manual measurement and automated measurement. Manual measurement typically relies on traditional measuring tools such as vernier calipers or micrometers, while automated measurement usually utilizes measuring instruments.

[0003] Among the above measurement methods, manual measurement is subject to errors, and the measurement results are greatly affected by differences in personal experience and skills, resulting in poor repeatability and reliability. Automated measurement is limited by the structure of the instrument itself, and the measurement efficiency is low when dealing with bushings of different sizes, which affects the measurement of bushings.

The sliding direction of the first positioning plate is perpendicular to the sliding direction of the second positioning plate. The measuring base is equipped with a first control assembly for controlling the sliding of the first positioning plate and a second control assembly for controlling the sliding of the second positioning plate.

[0007] By adopting the above technical solution, when measuring a workpiece, the operator first places the sample on the measuring base, and uses the first control component to make the first positioning plate contact the groove on the inner wall of the sample, and uses the second control component to make the second positioning plate contact the groove on the inner wall of the sample.

A first control assembly 4 for controlling the sliding of the first positioning plate 11 and a second control assembly 5 for controlling the sliding of the second positioning plate 12 are provided on the measuring base 1.

[0030] like Figure 2 and 3 As shown, the mounting assembly 3 includes a mounting bracket 31 and a fixing component. The mounting bracket 31 and the measuring base 1 are detachably connected. The measuring base 1 is provided with a connecting bolt 13 and a connecting hole 14. The connecting bolt 13 passes through the connecting hole 14 and is threadedly connected to the mounting bracket 31. A connecting step is provided on the wall of the connecting hole 14, and the connecting bolt 13 abuts against the connecting step. The mounting bracket 31 has a mounting hole 311. A mounting rod 21 is mounted on the measuring gauge 2. The mounting rod 21 is sleeved on the measuring needle of the measuring gauge 2, and the mounting hole 311 allows the mounting rod 21 to be inserted. The fixing component is a fixing bolt 32, which is threadedly connected to the mounting bracket 31. The fixing bolt 32 passes through the wall of the mounting hole 311 and abuts against the mounting rod 21. When it is necessary to install measuring gauge 2, the operator moves the mounting bracket 31 to a suitable position on the measuring base 1 according to the actual situation, and then screws in the connecting bolt 13 so that the connecting bolt 13 passes through the connecting hole 14 and is threadedly connected to the mounting bracket 31, thereby achieving the fixed installation of the mounting bracket 31; then the measuring gauge 2 is moved so that the mounting rod 21 is embedded in the mounting hole 311, and then the fixing bolt 32 is screwed in so that the fixing bolt 32 passes through the hole wall of the mounting hole 311 and abuts against the mounting rod 21, thereby positioning the mounting rod 21 in the mounting hole 311, thereby achieving the installation of measuring gauge 2, which facilitates the measurement of the workpiece on the measuring gauge 2.

The bottom ends of the first control block 42 and the first control rod 41 are fixedly connected. The operator can move the first positioning disk 11 according to the actual situation. When it is necessary to move the first positioning disk 11, the operator can move the first control rod 41. The first sliding hole 15 can limit the movement of the first control rod 41. The movement of the first control rod 41 can drive the movement of the first control block 42. The first auxiliary hole 16 can limit the movement of the first control block 42, thereby limiting the movement of the first positioning disk 11, which facilitates the first positioning disk 11 to limit the position of the workpiece.

[0032] like Figure 2 As shown, a plurality of first support blocks 43 are slidably connected to the first control rod 41. The plurality of first support blocks 43 are stacked, and the first positioning disk 11 is located above the first support blocks 43. The operator can adjust the height of the first positioning disk 11 according to the size of the workpiece by stacking the plurality of first support blocks 43 to meet the appropriate height of the first positioning disk 11, and then place the first positioning disk 11 on the first support blocks 43. A first nut 44 is threadedly connected to the first control rod 41. When the first positioning disk 11 is adjusted to the appropriate height, the operator screws in the first nut 44, so that the first nut 44 rotates to abut against the first positioning disk 11. At this time, the first control block 42 and the hole wall of the first auxiliary hole 16 abut against each other, thereby positioning the first control rod 41 and the first positioning disk 11, which facilitates the limiting of the workpiece by the first positioning disk 11.

[0033] like Figure 2 and 3 As shown, the second control component 5 includes a second control rod 51 and a second control block 52.

A second auxiliary hole 161 is provided on the wall of the second sliding hole 151, and the second control block 52 slides within the second auxiliary hole 161. The bottom ends of the second control block 52 and the second control rod 51 are fixedly connected. The operator can move the second positioning disk 12 according to the actual situation. When it is necessary to move the second positioning disk 12, the operator can move the second control rod 51. The second sliding hole 151 can limit the movement of the second control rod 51. The movement of the second control rod 51 can drive the movement of the second control block 52. The second auxiliary hole 161 can limit the movement of the second control block 52, thereby limiting the movement of the second positioning disk 12, which facilitates the second positioning disk 12 to limit the position of the workpiece.

[0034] like Figure 2 As shown, multiple second support blocks 53 are slidably connected to the second control rod 51. These second support blocks 53 are stacked, and the second positioning disk 12 is located above the second support blocks 53. The operator can adjust the height of the second positioning disk 12 according to the workpiece size by stacking the multiple second support blocks 53 to achieve the appropriate height. The second positioning disk 12 is then placed on the second support blocks 53. A second nut 54 is threaded onto the second control rod 51. After the second positioning disk 12 is adjusted to the appropriate height, the operator screws in the second nut 54, causing it to rotate until it abuts against the second positioning disk 12. At this point, the second control block 52 and the wall of the second auxiliary hole 161 abut against each other, thereby positioning the second control rod 51 and the second positioning disk 12, facilitating the limiting of the workpiece by the second positioning disk 12.

[0035] The implementation principle of the device for measuring the inner groove dimension of a bushing-type workpiece according to an embodiment of this application is as follows:

[0036] When a workpiece needs to be measured, the operator first places the sample on the measuring base 1, adjusts the height of the first positioning plate 11 by stacking the first support block 43, adjusts the height of the second positioning plate 12 by the second support block 53, and moves the first control lever 41 and the second control lever 51 so that both the first positioning plate 11 and the second positioning plate 12 are in contact with the groove on the inner wall of the sample. The measuring needle of the measuring dial indicator 2 is in contact with the groove on the inner wall of the sample. At this time, the value of the measuring dial indicator 2 is the standard value. Then, the measuring needle is slightly retracted, the sample is taken out, and the workpiece to be measured is placed on the measuring base 1. The measurement is performed again by measuring the needle. The measured dimension is compared with the measured dimension of the sample to obtain the dimensional tolerance, thereby realizing the measurement of the workpiece.
