[0038] In the embodiment of the application, the measuring device 100 comprises the measuring platform 1, the positioning assembly 2 and the measuring assembly 3, wherein the measuring platform 1 is used to carry the positioning assembly 2 and the measuring assembly 3, the positioning shaft 21 of the positioning assembly 2 is used to assemble the reel 1', and the axle 11' of the reel 1' and the positioning shaft 21 are fitted together to fix the reel 1' to the mounting section 211, so that the rotation of the positioning shaft 21 drives the rotation of the reel 1'.

[0039] In the actual measurement process, the first measuring end 311 contacts the surface of the axle 11' for measurement, the first measuring unit 31 rotates one circle relative to the surface of the axle 11' and obtains the concentricity of the axle 11' according to the distance value read in the first direction Y, the second measuring end 321 contacts the surface of the disc 12' for measurement, the second measuring end 321 rotates relative to the disc 12' and obtains the deformation degree of the disc 12' according to the distance value read in the axial direction X of the positioning shaft, and the reel 1' rotates one circle with the positioning shaft 21, so that the measurement of the concentricity and the deformation degree of the surface of the reel 1' can be realized synchronously, thereby effectively reducing the measurement time, and the measurement by the measuring device 100 can reduce the error in manual measurement and effectively improve the measurement accuracy.

[0040] Specifically, the measurement platform 1 is provided with a vacancy corresponding to the part of the mounting section 211, which is used to accommodate the positioning assembly 2 and the rotation of the reel 1', so as to facilitate the installation or disassembly of the reel 1' directly from the vacancy, further accelerate the overall measurement time, and at the same time, the vacancy part can be used for corresponding to various different sizes of the reel 1', so as to increase the universality of the measurement device 100 in the application.

[0041] In some embodiments, the positioning assembly 2 further comprises a shaft seat, which is installed on the measurement platform 1, and the positioning shaft 21 is installed on the shaft seat for rotation, and the shaft seat is used to provide support force for the positioning shaft 21 to ensure the smooth rotation of the positioning shaft 21.

[0042] Please refer to Figures 2 to 3 In the embodiments of the application, the measurement device 100 comprises a first longitudinal movement assembly 4, a second longitudinal movement assembly 5 and a transverse movement assembly 6, wherein the first longitudinal movement assembly 4 is connected with the first measurement unit 31 to drive the first measurement unit 31 to move along the first direction Y; the second longitudinal movement assembly 5 is connected with the second measurement unit 32 to drive the second measurement unit 32 to move along the first direction Y; the transverse movement assembly 6 is installed on the measurement platform 1, and the transverse movement assembly 6 is connected with the first longitudinal movement assembly 4 to drive the first longitudinal movement assembly 4 to move along the axial direction X of the positioning shaft, and the transverse movement assembly 6 is connected with the second longitudinal movement assembly 5 to drive the second longitudinal movement assembly 5 to move along the axial direction X of the positioning shaft.

[0043] It can be understood that the first measurement unit 31 has a movement stroke along the first direction Y by being connected with the first longitudinal assembly, and the first longitudinal assembly has a movement stroke along the axial direction X of the positioning shaft relative to the transverse movement assembly 6, so that the first measurement unit 31 has a movement stroke along the first direction Y and the axial direction X of the positioning shaft relative to the measurement platform 1, thereby facilitating the adjustment of the positional relationship between the first measurement unit 31 and the positioning shaft 21, avoiding during the installation and disassembly of the reel 1' and the positioning shaft 21, and moving in the direction close to the positioning shaft 21 after assembly to measure the reel 1'. In addition, the movable first measurement unit 31 can not only measure the concentricity of the reel 1' at different positions, but also adapt to reels 1' of different sizes and shapes, thereby improving the universality of the measurement device 100.

[0044] Specifically, in the embodiments of the application, the first measurement unit 31 can also be used to measure the concentricity of the two wheels 12' by adjusting the position, and by obtaining the concentricity of the reel 1' axle 11' and the two wheels 12', the concentricity and deformation state of the reel 1' can be preliminarily judged.

[0045] Similarly, the second measuring unit 32 also has a moving stroke along the first direction Y and the axial direction X of the positioning shaft relative to the measuring platform 1, thus also having the above beneficial effects of the first measuring unit 31, in addition, the second measuring unit 32 can adjust the distance between the positioning shaft 21, so as to change the measurement position of the drum 12', so as to measure the deformation degree of different positions of the drum 12', and improve the comprehensiveness of the measuring device 100 in measuring the drum 1'.

[0046] Please refer to Figure 2 and Figure 3 , the first measuring unit 31 comprises a first dial gauge 312, the first dial gauge 312 is installed on the first longitudinal moving assembly 4, and the probe of the first dial gauge 312 forms the first measuring end 311; the second measuring unit 32 comprises a second dial gauge 322, the second dial gauge 322 is installed on the second longitudinal moving assembly 5, and the probe of the second dial gauge 322 forms the second measuring end 321; wherein the first measuring end 311 extends along the first direction Y, and the second measuring end 321 extends along the axial direction X of the positioning shaft. It can be understood that in the embodiment of the application, the first measuring unit 31 and the second measuring unit 32 both use dial gauges as measuring tools, the measuring accuracy of the dial gauges is relatively high, the dial gauges can detect the slight changes of objects, and the measuring principle of the dial gauges is based on spring and gear mechanism, so that the dial gauges have good repeatability and reduce random errors in measurement.

[0047] In the application, the first dial gauge 312 comprises a gauge body and a probe, the probe of the first dial gauge 312 forms the first measuring end 311 and is used to contact the drum 1', in the actual measurement process, the probe of the first dial gauge 312 extends along the first direction Y, so as to be perpendicular to the axial direction X of the positioning shaft, so as to ensure that the probe of the first dial gauge 312 is perpendicular to the contact surface of the drum 1', and effectively reduces the measurement error.

[0048] Specifically, in the measurement process of the first dial gauge 312 on the drum 1', a suitable starting position is first determined to ensure that the probe of the first dial gauge 312 is perpendicular to the measuring surface, the first dial gauge 312 is zeroed, then the positioning shaft 21 is rotated to drive the rotation of the drum 1', and the maximum reading and the minimum reading of the first dial gauge 312 are recorded, the deviation value of the concentricity of the hub 11' and the drum 12' of the drum 1' can be obtained by half of the difference between the maximum reading and the minimum reading measured respectively, it can be understood that if the hub 11' and the drum 12' of the drum 1' are completely concentric, the reading of the first dial gauge 312 in the rotation process should be constant, and in the actual situation, as long as the number of deviation values is within a certain range, the drum 1' can be judged to be qualified.

[0049] Similarly, the measurement of the second dial gauge 322 to the reel 1' also needs to follow the above steps, the probe of the second dial gauge 322 extends along the axial direction X of the positioning shaft, so as to keep perpendicular to the wheel disc 12', the reel 1' rotates with the rotation of the positioning shaft 21, the second dial gauge 322 measures the flatness of the surface of the wheel disc 12', the difference between the maximum reading and the minimum reading of the second dial gauge 322 can reflect the maximum deformation of the measured area of the surface of the wheel disc 12', and the fluctuation range of the average reading can also reflect the deformation of the entire measured area of the wheel disc 12', in actual cases, as long as the fluctuation range of the reading is within a certain range, the reel 1' can be judged to be qualified.

[0050] In some other embodiments, the first measuring unit 31 and the second measuring unit 32 also include other measuring structures, such as optical measuring instruments, laser range finders, three-coordinate measuring machines, etc., which are not limited in the present application as long as the measuring effect can be achieved.

[0051] Reference can be made to Figures 3 to 4 The measuring device 100 includes two groups of second measuring units 32; in the axial direction X of the positioning shaft, the two groups of second measuring units 32 are arranged on opposite sides of the first measuring unit 31, and the two groups of second measuring units 32 are oppositely arranged. It should be noted that the wheel shaft 11' of the reel 1' is provided with a wheel disc 12' at both ends, in the present application, the reel 1' is installed at the positioning shaft 21, and the two second measuring units 32 can simultaneously measure the two wheel discs 12' on both sides along the axial direction X of the positioning shaft, thereby measuring the deformation degree of the wheel discs 12' on both sides. The two groups of second measuring units 32 simultaneously measure, which reduces the measurement time and steps, improves the measurement efficiency, and is suitable for rapid detection in large-scale production.

[0052] From the perspective, the wheel disc 12' is located on both sides of the wheel shaft 11', when the first measuring unit 31 measures the concentricity of the wheel shaft 11', the two groups of second measuring units 32 are arranged on both sides of the first measuring unit 31 along the axial direction X of the positioning shaft, and the first measuring unit 31 and the two groups of second measuring units 32 do not interfere with each other when measuring the reel 1' respectively.

[0053] Specifically, the measuring device 100 includes two groups of second longitudinal moving assemblies 5, and the two groups of second measuring units 32 are installed one by one on the two groups of second longitudinal moving assemblies 5; the transverse moving assembly 6 includes a transverse guide rail 61 and a plurality of transverse sliding blocks 62 slidingly installed on the transverse guide rail 61, the transverse guide rail 61 extends along the axial direction X of the positioning shaft, and a part of the transverse sliding blocks 62 are connected with one of the two groups of second longitudinal moving assemblies 5, and the other part of the transverse sliding blocks 62 are connected with the other group of second longitudinal moving assemblies 5.

[0054] It can be understood that the transverse guide rail 61 is installed on the measuring platform 1, each second measuring unit 32 corresponds to a set of longitudinal moving assemblies, and the two second measuring units 32 can move along the axial direction X of the positioning axis relative to the measuring platform 1, which facilitates the installation, disassembly and measurement of the reel 1'. The transverse moving assembly 6 includes the transverse guide rail 61 and the transverse sliding block 62, which can accurately control the movement of the second measuring unit 32 along the axial direction X of the positioning axis, and ensure the stability of the movement of the second measuring unit 32 along the axial direction X of the positioning axis. It is worth noting that a part of the transverse sliding block 62 is connected with the first longitudinal moving assembly 4, which ensures the stability of the movement of the first measuring unit 31 along the axial direction X of the positioning axis.

[0055] Correspondingly, with reference to Figure 4 In some embodiments, the second longitudinal moving assembly 5 includes a longitudinal guide rail 41 and a longitudinal sliding block 42 slidably installed on the longitudinal guide rail 41, the longitudinal guide rail 41 extends along the first direction Y, and the longitudinal sliding block 42 is connected with the second measuring unit 32 to drive the second measuring unit 32 to move along the first direction Y, thereby ensuring the accurate and stable movement of the second measuring unit 32 along the first direction Y. In addition, the first longitudinal moving assembly 4 also includes a longitudinal guide rail 41 and a longitudinal sliding block 42 slidably installed on the longitudinal guide rail 41, thereby ensuring the accurate and stable movement of the first measuring unit 31 along the first direction Y.

[0056] In other embodiments, with reference to Figure 4 The transverse moving assembly 6 further includes a first locking structure 63 connected with the transverse sliding block 62, and the first locking structure 63 has a fixed end close to the transverse guide rail 61. The distance between the fixed end and the transverse guide rail 61 can be adjusted by adjusting the handle of the first locking structure 63, so that the fixed end abuts against the transverse guide rail 61 to limit the movement of the transverse sliding block 62. Correspondingly, the first longitudinal moving assembly 4 and the second longitudinal moving assembly 5 each include a second locking structure 43 capable of limiting the movement of the longitudinal sliding block 42. In this way, the positions of the first measuring unit 31 and the second measuring unit 32 in the measuring state can be locked, which facilitates the adjustment and locking of the positions of the first measuring unit 31 and the second measuring unit 32, maintains the stability of the measuring process, and reduces the error of the measurement results.

[0057] In addition, in order to further limit the movement range of the first longitudinal moving assembly 4 and the second longitudinal moving assembly 5, the measuring assembly 3 further includes a plurality of limiting pins 33 arranged at both ends of the transverse guide rail 61 along the axial direction X of the positioning axis, so that the transverse sliding block 62 can only slide within the range defined by the plurality of limiting pins 33, thereby preventing the transverse sliding block 62 from being pulled out of the transverse guide rail 61, and increasing the practicability of the measuring device 100.

[0058] Please continue to refer to Figure 4 The positioning shaft 21 comprises a first end and a second end opposite along the axial direction X of the positioning shaft; the positioning assembly 2 further comprises a holding assembly 22, and the holding assembly 22 is mounted on at least one of the first end and the second end, and is used for being held by an operator to drive the positioning shaft 21 to rotate around the axial direction thereof. In the embodiment of the present application, the positioning shaft 21 is rotated by rotating the holding assembly 22, which is convenient for manual operation. The specific mounting position of the holding assembly 22 is not limited as long as it can be connected to the positioning shaft 21. In the present application, the holding assembly 22 is connected to the end of the positioning shaft 21, which can facilitate the operator to hold and rotate the holding assembly 22.

[0059] In some embodiments, the holding assembly 22 is mounted on both the first end and the second end of the positioning shaft 21, and the positioning shaft 21 can be rotated on both sides along the axial direction X of the positioning shaft, which ensures the convenience of the operator to rotate the positioning shaft 21.

[0060] Specifically, the holding assembly 22 comprises a hand wheel 221, a quick-release handle 222, etc., and different holding assemblies 22 can be selected according to actual needs, which are not limited in the present application. In some embodiments, the quick-release handle 222 is mounted on the first end of the positioning shaft 21, and the quick-release handle 222 is detachably mounted on the first end of the positioning shaft 21, so that the reel 1' is conveniently mounted from the first end. After the reel 1' is mounted, the quick-release handle 222 is mounted to the positioning shaft 21, and the operator operates the quick-release handle 222 to rotate the positioning shaft 21 to complete the measurement.

[0061] Referring to Figure 4 The positioning assembly 2 further comprises a damping adjustment member 23, and the damping adjustment member 23 is mounted on the measurement platform 1. The damping adjustment member 23 comprises two abutting portions 231, and the two abutting portions 231 are separately arranged on opposite sides of the positioning shaft 21 along the first direction Y and abut against the positioning shaft 21. The two abutting portions 231 move along the first direction Y to adjust the pressure on the positioning shaft 21. Specifically, the two abutting portions 231 are close to each other along the first direction Y to clamp the positioning shaft 21, so that the pressure for rotating the positioning shaft 21 is large, which increases the resistance of the positioning shaft 21 to rotate. Under the condition of applying the same tension, the effect of slowing down the rotation speed of the positioning shaft 21 can be achieved. Correspondingly, the two abutting portions 231 are away from each other along the first direction Y to reduce the pressure on the positioning shaft 21, thereby reducing the resistance of the positioning shaft 21 to rotate. Under the condition of applying the same tension, the effect of increasing the rotation speed of the positioning shaft 21 can be achieved. The operator can adjust the damping adjustment key according to the actual situation to control the rotation speed of the positioning shaft 21.

[0062] In order to facilitate the measurement of the concentricity of the reel 1', the first measurement end 311 comprises a connecting rod 311a extending along the first direction Y and spaced apart from the mounting section 211, and a roller 311b connected to the connecting rod 311a and used to abut against the reel 1'. It can be understood that, in some embodiments, the first measurement unit 31 comprises a first dial gauge 312 comprising a gauge body and a probe, one end of the connecting rod 311a being connected to the probe and the other end being connected to the roller 311b, the roller 311b being rotatable about an axis thereof, the axis of the roller 311b being parallel to the axis X of the positioning shaft.

[0063] During the measurement, the roller 311b is used to make smooth contact with the measurement section of the reel 1', reducing the vibration and displacement of the first measurement end 311 caused by the contact between the first measurement unit 31 and the reel 1', ensuring the stability of the measurement process, reducing the errors caused by poor contact, and effectively reducing the wear on the measurement position of the reel 1'.

[0064] Please refer to Figure 2 and Figure 5 , the measuring device 100 further comprises a winding structure 7 comprising a winding shaft 71, the axis of the winding shaft 71 being parallel to the axis X of the positioning shaft, the winding shaft 71 being rotatably mounted to the measuring platform 1 along the axis thereof, and the winding shaft 71 being used to wind the chip strip; wherein one part of the chip strip is wound around the shaft 11' of the reel 1', and under the synchronous rotation of the positioning shaft 21 and the winding shaft 71, the positioning shaft 21 is used to pull the chip strip to transfer the remaining part of the chip strip wound around the winding shaft 71 to the shaft 11' of the reel 1'.

[0065] It should be noted that, during the measurement of the reel 1' by the measuring device 100, there is no chip strip connected to the reel 1', and the measuring assembly 3 is used to detect the reel 1' alone. When the measurement of the reel 1' is completed and it is confirmed that the reel 1' is measured to be qualified, the concentricity and the deformation degree are within the preset range, at this time the chip strip is connected to the reel 1' and is stored by the reel 1'.

[0066] In the above embodiments, the axis of the winding shaft 71 is parallel to the axis X of the positioning shaft, ensuring that the two can be kept synchronous during rotation, and the chip strip can be subjected to uniform tension during the transfer from the winding shaft 71 to the reel 1', so that it can be smoothly transferred from the winding shaft 71 to the reel 1' and wound to the shaft 11' of the reel 1'. The above process can have a protective effect on the chip strip, reducing the probability of damage.

[0067] It can be understood that the winding structure 7 is used for winding the chip strip to the winding shaft 71, the winding structure 7 and the positioning shaft 21 are arranged in the first direction Y, and the winding shaft 71 and the positioning shaft 21 correspond to each other, so that the chip strip on the winding shaft 71 is subjected to uniform traction, and the process of transferring the chip strip to the reel 1' is more smooth.

[0068] In addition, the winding shaft 71 has a winding section 711 for accommodating the chip strip, and the winding structure 7 further comprises two winding flaps 72 connected to both sides of the winding section 711. Specifically, the winding section 711 and the mounting section 211 are arranged in the first direction Y, the chip strip is wound to the winding section 711, and the winding flaps 72 are located at both ends of the winding section 711, facilitating the hanging of the winding strip, ensuring that the winding strip can be stably arranged, and reducing the risk of falling off from the winding section 711. One of the winding flaps 72 is further connected with a position adjusting screw 721 for adjusting the spacing of the two winding flaps 72, so as to be suitable for winding of different chip strips, so as to improve the versatility of the winding structure 7.
