[0015] The floating detection device of this utility model has the following advantages compared with the prior art:

[0016] 1. By having the operator hold and push the guide shaft, the guide shaft moves the inspection head towards the tubular workpiece, allowing it to be inserted into the inner diameter of the workpiece. When the inspection head is inserted into the workpiece, it proves that the inner diameter of the workpiece meets the lower tolerance requirement (inner diameter greater than the minimum standard). Then, the inspection head is replaced, and the guide shaft moves the inspection head again, allowing it to be inserted into the inner diameter of the workpiece. When the inspection head cannot be inserted into the inner diameter, it proves that the inner diameter of the workpiece meets the upper tolerance requirement (inner diameter less than the maximum standard). By inserting two different types of inspection heads into the tubular workpieces to be inspected, the inner diameter of the workpiece can be determined to meet the tolerance requirements. Compared to using vernier calipers, this method is more efficient and avoids errors, thus improving inspection accuracy. Because the clamping shaft and the floating shaft can rotate relative to each other, the detection head can automatically rotate during the process of embedding the detection head into the tubular workpiece to adjust its position. This reduces the difficulty of embedding the detection head into the tubular workpiece, improves the user experience, and eliminates the need for manual rotation of the guide shaft. It also avoids situations where the detection head cannot rotate due to the operator holding the guide shaft, thus improving the detection accuracy of the product.

[0017] 2. By setting the guide shaft and the guide table to an intermediate fit, it is possible to avoid the situation where the guide sleeve cannot guide the guide shaft due to excessive gap between the guide shaft and the guide sleeve, and it is also possible to avoid the situation where the guide shaft cannot move within the guide sleeve due to insufficient gap between the guide shaft and the guide sleeve. This allows the guide shaft to move within the guide sleeve with high precision.

[0018] 3. By setting the first threaded hole through the floating shaft and the first blind hole in the detection head, the first bolt passes through the first blind hole and is embedded in the first threaded hole, so that the floating shaft and the detection head are connected together by the first bolt, thereby realizing the synchronous rotation and movement of the floating shaft and the detection head. At the same time, the first bolt can be hidden in the first blind hole, thereby avoiding interference between the first bolt and other components, thus improving the user experience of the product.

[0019] 4. By fitting the shim onto the outside of the floating shaft and ensuring that the shim is in contact with both the detection head and the clamping shaft, direct contact between the detection head and the clamping shaft is avoided. This prevents the detection head from scratching the clamping shaft when it rotates, thus improving product quality.

[0020] 5. By setting the second threaded hole in the guide shaft near the transition shaft and setting the second blind hole in the transition shaft, the second bolt passes through the second blind hole and is embedded in the second threaded hole, so that the second bolt connects the guide shaft and the transition shaft together. This allows the second bolt to be hidden in the transition shaft to avoid interference between the second bolt and the clamping shaft, thereby improving the user experience of the product.

[0021] 6. By setting the second positioning groove in one end of the transition shaft near the guide shaft, connecting the second positioning groove with the second blind hole, and embedding at least part of the guide shaft into the second positioning groove, the guide shaft can be positioned by the second positioning groove, thereby ensuring that the second threaded hole is opposite to the second blind hole, which facilitates the second bolt to pass through the second blind hole and the second bolt to be embedded in the second threaded hole, thereby improving the user experience of the product.

[0022] 7. By setting the slot on the outer wall of the guide shaft and making the slot opposite to the card plate, the card plate can be rotated so that the card plate can be embedded in the slot, thereby limiting the guide shaft to prevent the guide shaft from moving along its axis and improving the stability of the guide shaft.

[0023] 8. By setting the support part on the outer wall of the guide shaft, fitting the spring on the outside of the guide shaft, attaching one end of the spring to the support part, and attaching the other end of the spring to the connecting block, the connecting block supports the support part and the guide shaft through the spring. This allows the support part to compress the spring when the worker moves the support part towards the column via the guide shaft. Consequently, when the worker does not apply any working force to the guide shaft, the spring resets and drives the support part and the guide shaft to move away from the column, thus promoting the reset of the guide shaft.

[0024] 9. By installing an L-shaped limiting block on the side wall of the column near the transition shaft and positioning the limiting block opposite the transition shaft, the limiting block can provide a support groove for the transition shaft when the filter shaft moves to the column, thereby improving the stability of components such as the transition shaft, guide shaft, and detection head.

[0025] 10. By setting two positioning holes on the side wall of the column, passing two set screws through the two positioning holes respectively, and making the two set screws fit into the two guide sleeves respectively, the set screws are threadedly connected to the positioning holes. This allows the set screws to fix the guide sleeves inside the column, thereby preventing the guide shaft from moving the guide sleeves when the guide shaft moves, thus improving the user experience of the product.

Detailed Implementation

[0032] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0033] A floating detection device, such as Figures 1 to 4 As shown, the floating detection device includes: a base plate 10, a column 11, a mounting hole 12, a guide sleeve 13, a guide shaft 14, a transition shaft 15, a clamping shaft 16, a receiving groove 17, a floating shaft 18, and a detection head 19; the column 11 is mounted on the base plate 10, and the column 11 is perpendicular to the base plate 10; the mounting hole 12 is set inside the column 11; the guide sleeve 13 is a hollow cavity with openings at both ends, and two guide sleeves 13 are embedded in the mounting hole 12; the guide shaft 14 passes through the two guide sleeves 13 in sequence; the transition shaft 15... The guide shaft 14 is connected to the end of the guide shaft 14; therefore, the clamping shaft 16 is connected to the transition shaft 15; the receiving groove 17 has a T-shaped cross section and is disposed inside the clamping shaft 16; the floating shaft 18 has a T-shaped cross section, at least part of the floating shaft 18 is embedded in the receiving groove 17, and the end of the floating shaft 18 is located outside the clamping shaft 16; the detection head 19 is connected to the end of the floating shaft 18, and the end of the detection head 19 away from the floating shaft 18 is provided with a chamfer; wherein, there is a gap between the floating shaft 18 and the receiving groove 17.

[0034] By mounting the column 11 on the base plate 10 and making the column 11 perpendicular to the base plate 10, the base plate 10 can support the column 11, thereby improving the stability of the column 11. By setting the mounting hole 12 inside the column 11, embedding two guide sleeves 13 into the mounting hole 12, and allowing the guide shaft 14 to pass through the two guide sleeves 13 in sequence, the column 11 can support the guide shaft 14 through the two guide sleeves 13, thereby allowing the guide shaft 14 to move within the two guide sleeves 13 to adjust the relative position between the guide shaft 14 and the column 11. By connecting the end of the transition shaft 15 to the guide shaft 14 and the clamping shaft 16 to the transition shaft 15, the guide shaft 14, transition shaft 15, and clamping shaft 16 are connected together, enabling synchronous movement of the guide shaft 14, transition shaft 15, and clamping shaft 16. By placing a T-shaped receiving groove 17 inside the clamping shaft 16 and embedding a T-shaped floating shaft 18 inside the receiving groove 17, the clamping shaft 16 and floating shaft 18 are engaged, allowing the clamping shaft 16 to drive the floating shaft 18 to move, and thus enabling relative rotation between the clamping shaft 16 and the floating shaft 18. By connecting the detection head 19 to the end of the floating shaft 18 and placing a chamfer on the end of the detection head 19 away from the floating shaft 18, the floating shaft 18 and the detection head 19 can move and rotate synchronously, reducing the difficulty of embedding the detection head 19 into tubular workpieces, and thus enabling the detection of the inner diameter of tubular workpieces.

[0035] Using the above structure, by having the operator hold and push the guide shaft 14, the guide shaft 14 moves the inspection head 19 towards the tubular workpiece, thereby inserting the inspection head 19 into the inner hole of the tubular workpiece. When the inspection head 19 is embedded in the tubular workpiece, it proves that the inner diameter of the tubular workpiece meets the lower tolerance requirement (inner diameter greater than the minimum standard). Then, the inspection head 19 is replaced, and the guide shaft 14 moves the inspection head 19, thereby inserting the inspection head 19 into the inner hole of the tubular workpiece. When the inspection head 19 cannot be embedded in the inner hole of the workpiece, it proves that the inner diameter of the tubular workpiece meets the upper tolerance requirement (inner diameter less than the maximum standard). Since the clamping shaft 16 and the floating shaft 18 can rotate relative to each other, the detection head 19 can automatically rotate during the process of embedding the detection head 19 into the tubular workpiece to adjust the position of the detection head 19, thereby reducing the difficulty of embedding the detection head 19 into the tubular workpiece, improving the user experience of the product, and thus eliminating the need for operators to manually rotate the guide shaft 14. At the same time, it can also avoid the situation where the detection head 19 cannot rotate due to the operator holding the guide shaft 14, thereby improving the detection accuracy of the product.

[0036] In the embodiments of this utility model, the guide shaft 14 and the guide sleeve 13 are in transition fit.

[0037] By setting the guide shaft 14 and the guide table to an intermediate fit, it is possible to avoid the situation where the guide sleeve 13 cannot guide the guide shaft 14 due to excessive gap between the guide shaft 14 and the guide sleeve 13, and also to avoid the situation where the guide shaft 14 cannot move within the guide sleeve 13 due to insufficient gap between the guide shaft 14 and the guide sleeve 13. This ensures that the guide shaft 14 can move within the guide sleeve 13 with high precision.

[0038] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device further includes: a first threaded hole 20, a first blind hole 21, and a first bolt; the first threaded hole 20 is provided with a first internal thread, and the first threaded hole 20 is disposed through the floating shaft 18; the first blind hole 21 is disposed in the detection head 19; the outer wall of the first bolt is provided with a first external thread, the first bolt passes through the first blind hole 21, and the first bolt is embedded in the first threaded hole 20; wherein, the first internal thread and the first external thread are compatible.

[0039] By setting the first threaded hole 20 through the floating shaft 18 and the first blind hole 21 in the detection head 19, the first bolt passes through the first blind hole 21 and is embedded in the first threaded hole 20. This allows the floating shaft 18 and the detection head 19 to be connected together by the first bolt, thereby enabling the floating shaft 18 and the detection head 19 to rotate and move synchronously. At the same time, it also allows the first bolt to be hidden in the first blind hole 21, thus avoiding interference between the first bolt and other components and improving the user experience of the product.

[0040] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device also includes: a gasket 22 and a first positioning groove; the gasket 22 is fitted on the outside of the floating shaft 18, and the gasket 22 is in contact with the detection head 19 and the pressing shaft 16 at the same time; the first positioning groove is disposed in the end of the detection head 19 near the gasket 22, the first positioning groove is connected to the first blind hole 21, and at least part of the floating shaft 18 is embedded in the first positioning groove.

[0041] By fitting the shim 22 onto the outside of the floating shaft 18 and ensuring that the shim 22 simultaneously contacts both the detection head 19 and the clamping shaft 16, direct contact between the detection head 19 and the clamping shaft 16 is avoided. This prevents the detection head 19 from scratching the clamping shaft 16 when it rotates, thus improving product quality. By placing the first positioning groove within the end of the detection body near the shim 22 and embedding at least a portion of the floating shaft 18 into the first positioning groove, the floating shaft 18 is positioned relative to the detection head 19. This ensures that the first threaded hole 20 within the floating shaft 18 aligns with the first blind hole 21, facilitating the passage of the first bolt through the first blind hole 21 and ensuring that the first bolt is embedded within the first threaded hole 20, thereby improving the user experience.

[0042] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device also includes: a second threaded hole 23, a second blind hole 24, and a second bolt; the second threaded hole 23 is provided with a second internal thread, and the second threaded hole 23 is located in one end of the guide shaft 14 near the transition shaft 15; the second blind hole 24 is located in the transition shaft 15; the outer wall of the second bolt is provided with a second external thread, the second bolt passes through the second blind hole 24, and the second bolt is embedded in the second threaded hole 23; wherein, the second internal thread and the second external thread are compatible.

[0043] By setting the second threaded hole 23 in one end of the guide shaft 14 near the transition shaft 15 and setting the second blind hole 24 in the transition shaft 15, the second bolt passes through the second blind hole 24 and is embedded in the second threaded hole 23, so that the second bolt connects the guide shaft 14 and the transition shaft 15 together. This allows the second bolt to be hidden in the transition shaft 15, so as to avoid interference between the second bolt and the clamping shaft 16 and improve the user experience of the product.

[0044] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device further includes: a second positioning groove, a positioning ring groove, and a positioning part 26; the second positioning groove is disposed in the end of the transition shaft 15 near the guide shaft 14, the second positioning groove is connected to the second blind hole 24, and at least part of the guide shaft 14 is embedded in the second positioning groove; the positioning ring groove is disposed on the outer wall of the end of the transition shaft 15 near the pressing shaft 16; the positioning part 26 is annular, the positioning part 26 is disposed on the end of the pressing shaft 16 near the filter shaft, and the positioning part 26 is embedded in the positioning ring groove.

[0045] By setting the second positioning groove in the end of the transition shaft 15 near the guide shaft 14, connecting the second positioning groove to the second blind hole 24, and embedding at least part of the guide shaft 14 into the second positioning groove, the guide shaft 14 positions the transition shaft 15 through the second positioning groove. This ensures that the second threaded hole 23 is aligned with the second blind hole 24, facilitating the passage of the second bolt through the second blind hole 24 and embedding the second bolt into the second threaded hole 23, thus improving the user experience. By setting the positioning ring groove on the outer wall of the transition shaft 15, and setting the annular positioning part 26 on the clamping shaft 16, and embedding the positioning part 26 into the positioning ring groove, the transition shaft 15 positions the clamping shaft 16 through the positioning ring groove and the positioning part 26. This prevents relative displacement between the transition shaft 15 and the clamping shaft 16 along their radial direction, thereby improving the positional accuracy of the transition shaft 15 and the clamping shaft 16.

[0046] In embodiments of this utility model, such as Figures 1 to 4As shown, the floating detection device also includes: a connecting block 27, a clamping plate 29, and a clamping groove 30; the top of the connecting block 27 is provided with an installation groove 28, the connecting block 27 is connected to the side wall of the column 11 away from the transition shaft 15, and the connecting block 27 is located below the guide shaft 14; at least part of the clamping plate 29 is embedded in the installation groove 28, and one end of the clamping plate 29 is rotatably connected to the connecting block 27; the clamping groove 30 is provided on the outer wall of the guide shaft 14, and the clamping groove 30 is opposite to the clamping plate 29.

[0047] By connecting the connecting block 27 to the side wall of the column 11 opposite to the transition shaft 15, at least part of the clamping plate 29 is embedded in the mounting groove 28, and one end of the clamping plate 29 is rotatably connected to the connecting block 27, so that the column 11 supports the connecting block 27, thereby enabling the clamping plate 29 to rotate within the mounting groove 28; by setting the clamping groove 30 on the outer wall of the guide shaft 14 and making the clamping groove 30 opposite to the clamping plate 29, the clamping plate 29 can be rotated so that the clamping plate 29 can be embedded in the clamping groove 30, thereby limiting the guide shaft 14 to prevent the guide shaft 14 from moving along its axis, thus improving the stability of the guide shaft 14.

[0048] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device also includes: a support part 31 and a spring; the support part 31 is disposed on the outer wall of the guide shaft 14, and the support part 31 is located on the side of the connecting block 27 away from the column 11; the spring is sleeved on the outside of the guide shaft 14, one end of the spring is in contact with the support part 31, and the other end of the spring is in contact with the connecting block 27.

[0049] By placing the support part 31 on the outer wall of the guide shaft 14, and fitting the spring on the outside of the guide shaft 14, with one end of the spring in contact with the support part 31 and the other end in contact with the connecting block 27, the connecting block 27 supports the support part 31 and the guide shaft 14 through the spring. This allows the support part 31 to compress the spring when the worker moves the support part 31 towards the column 11 via the guide shaft 14. Consequently, when the worker does not apply any working force to the guide shaft 14, the spring resets and moves the support part 31 and the guide shaft 14 away from the column 11, thus promoting the reset of the guide shaft 14.

[0050] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device also includes: a limiting block 33; the limiting block 33 is L-shaped, and the limiting block 33 is installed on the side wall of the column 11 near the transition shaft 15, and the limiting block 33 is opposite to the transition shaft 15.

[0051] By installing an L-shaped limiting block 33 on the side wall of the column 11 near the transition shaft 15 and positioning the limiting block 33 opposite the transition shaft 15, the limiting block 33 can provide a support groove for the transition shaft 15 when the filter shaft moves to the column 11, thereby improving the stability of components such as the transition shaft 15, the guide shaft 14, and the detection head 19.

[0052] In embodiments of this utility model, such as Figures 1 to 4 As shown, the floating detection device also includes: positioning holes 34 and set screws; a third internal thread is provided in the positioning holes 34, and two positioning holes 34 are provided on the side wall of the column 11, and the two positioning holes 34 are respectively opposite to the two guide sleeves 13; a third external thread is provided on the outer wall of the set screws, and the two set screws pass through the two positioning holes 34 respectively, and the two set screws are respectively in contact with the two guide sleeves 13; wherein, the third internal thread and the third external thread are adapted to each other.

[0053] By setting two positioning holes 34 on the side wall of the column 11, passing two set screws through the two positioning holes 34 respectively, and making the two set screws fit against the two guide sleeves 13 respectively, the set screws are threadedly connected to the positioning holes 34. This allows the guide sleeves 13 to be fixed inside the column 11 using the set screws. This prevents the guide shaft 14 from moving the guide sleeves 13 when the guide shaft 14 moves, thus improving the user experience of the product.
