[0004] The lack of testing devices for reel-type through shafts of different specifications in related technologies results in poor versatility of testing devices. Furthermore, fixing the reel-type through shafts is cumbersome and requires additional tools, increasing the time cost and operational difficulty of testing, which is not conducive to the rapid testing needs in large-scale production. Summary of the Invention

[0005] Based on the above-mentioned technical problems, this application provides a comprehensive testing device with a disc-type through shaft, which aims to solve to some extent the technical problems of poor versatility of the testing device and the increased time cost and operational difficulty caused by the cumbersome fixing of the disc-type through shaft.

A support assembly is connected to the first slot, and the top of the support assembly supports the flange. A locking assembly is correspondingly disposed to each of the recesses. The locking assembly is connected to one of the second slots and has an inflation part disposed in the corresponding recess and abutting against the sidewall of the corresponding recess.

[0008] In some embodiments, the locking assembly includes: a locking screw threaded into a corresponding second slot, the locking screw having a through inflation channel; a slide rod slidably inserted into the inflation channel and spaced apart in the corresponding second slot; a reset member, the bottom end connected to the top of the slide rod and the top end connected to the side wall of the inflation channel; and an expansion member connected to the locking screw, the interior of the expansion member communicating with the inflation channel; wherein the slide rod slides upward within the inflation channel to increase the internal pressure of the expansion member, causing at least a portion of the expansion member to expand outward and abut against the corresponding recessed side wall, and at least a portion of the expansion member is configured as the inflation part.

[0009] In some embodiments, the expansion member includes: a connecting sleeve connected to the top of the locking screw; and an expansion sleeve, the bottom of which is fitted over the top of the connecting sleeve, at least a portion of which is flexible, and the periphery of which is configured as the inflation portion.

[0039] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] Figure 1 A schematic diagram of the structure of the through-shaft 10 with a disc in the related art is shown. Combined with... Figure 1 The through-shaft 10 with a disc in the related technology includes a shaft body 110, a splined body 120, and a flange 130. The shaft body 110 has a first end and a second end opposite to each other. The splined body 120 is coaxially connected to the first end of the shaft body 110, and the flange 130 is coaxially connected to the second end of the shaft body 110. Multiple recesses 131 are spaced apart on the circumference of the flange 130. For example, two recesses 131 are provided, and the two recesses 131 are symmetrically arranged about the central axis of the shaft body 110. The specifications of the shaft body 110, splined body 120, and flange 130 of the through-shaft 10 with a disc may vary depending on customer requirements.

[0041] Before leaving the factory, the through shaft 10 with disc needs to be inspected, such as for key dimensions and product surface defects, to confirm whether it meets the factory requirements.

[0042] The lack of a testing device in the relevant technology to adapt to different specifications of the through shaft 10 with a disc results in poor versatility of the testing device. Furthermore, fixing the through shaft 10 with a disc is cumbersome and requires additional tools, which increases the time cost and difficulty of operation, and is not conducive to the rapid testing needs in large-scale production.

[0043] Based on the above-mentioned technical problems, this application provides a comprehensive testing device 20 for a through shaft with a disc, which is used to test the through shaft with a disc 10. It aims to solve to a certain extent the technical problems of poor versatility of the testing device 20 and the increased time cost and operation difficulty caused by the relatively complicated fixing of the through shaft with a disc 10.

[0044] Figure 2 This illustration shows a structural schematic diagram of a comprehensive testing device 20 with a disc-type through-shaft according to one or more embodiments of this application, in conjunction with... Figure 2 The testing device 20 provided in this application includes a testing machine 210, a support assembly 220, and a locking assembly 230. The testing machine 210 has a worktable 211 and at least one sensor 215. At least one sensor 215 is disposed on the worktable 211. Figure 3 It shows Figure 2 The schematic diagram of the component arrangement on the workbench 211 in the diagram, combined with Figure 3 The top surface of the workbench 211 is provided with multiple slots 212, including a first slot 2121 and a second slot 2122; the support component 220 is connected to the first slot 2121, and the top of the support component 220 supports the flange 130; the locking component 230 and the recess 131 are provided in a one-to-one correspondence, the locking component 230 is connected to one of the second slots 2122, the locking component 230 has an inflation part 231, the inflation part 231 is provided in the corresponding recess 131 and abuts against the side wall of the corresponding recess 131.

[0045] The integrated testing device 20 with a through-shaft and disc provided in this application has a worktable 211 on its top surface, with multiple slots 212 including a first slot 2121 and a second slot 2122. A support assembly 220 is connected to the first slot 2121, and the top of the support assembly 220 can support a flange 130, thereby enabling axial positioning of the workpiece. A locking assembly 230 is correspondingly connected to one of the second slots 2122. The locking assembly 230 has an inflation part 231, which is disposed in a recess 131 on the circumference of the corresponding flange 130 and abuts against the side wall of the corresponding recess 131. The locking assembly 230 can radially position the flange 130, and the inflation part 231 can be inflated to different degrees to accommodate radial positioning of flanges 130 of different diameters, preventing workpiece displacement or loosening during inspection and improving the versatility of the inspection device 20. Furthermore, only the inflation part 231 needs to be inflated, simplifying operation and reducing workpiece positioning time, thereby reducing inspection time costs and operational difficulty. After the workpiece is positioned on the worktable 211, the sensor 215 located above the worktable 211 performs workpiece quality inspection, which is beneficial for the rapid inspection needs in large-scale production and has excellent practicality. The specific details of the inspection device 20 will now be further described with reference to the accompanying drawings.

[0046] In some embodiments, the worktable 211 can reciprocate relative to the inspection machine 210 in a predetermined direction to facilitate the inspection of workpieces assembled on the worktable 211 by inspection personnel. For example, in conjunction with... Figure 3The testing machine 210 is equipped with a fixed base 213, which has a guide groove 214 along a set direction. The worktable 211 is adapted to be disposed in the guide groove 214, and the workpiece is assembled on the worktable 211. When testing different parts of the workpiece, the inspector can manually push the worktable 211 to slide within the guide groove 214 to move the worktable 211 with the workpiece assembled to the required position; or, the testing machine 210 is equipped with a driving component, which can be a motor. The driving component is connected to the worktable 211. When testing different parts of the workpiece, the inspector can control the driving component to make the worktable 211 slide within the guide groove 214 to move the worktable 211 with the workpiece assembled to the required position. This application does not limit this.

[0047] In some other embodiments, the workbench 211 can rotate relative to the inspection machine 210, which also facilitates the inspection personnel to inspect the workpieces assembled on the workbench 211.

[0048] It should be noted that the worktable 211 can reciprocate relative to the testing machine 210 in a set direction, and the worktable 211 can rotate relative to the testing machine 210. These two conditions can coexist, or only one of them can be present. The specific conditions can be developed accordingly, and this application does not impose any restrictions on this.

[0049] In some embodiments, the sensor 215 located above the worktable 211 can be an optical vision inspection sensor to detect surface defects of the workpiece; or / and, the sensor 215 can be an ultrasonic inspection sensor to detect internal defects such as cracks, pores, and looseness of the workpiece, so as to achieve comprehensive non-destructive testing of the workpiece for data and surface defects.

[0050] Combination Figure 3 In some embodiments, the top surface of the worktable 211 is flat, and multiple slots 212 are provided on the top surface of the worktable 211 in a grid pattern, so as to select the appropriate slots 212 to install the support assembly 220 and the locking assembly 230 according to the flange 130 of the workpiece with different diameters.

[0051] Figure 4 A structural schematic diagram of the support component 220 is shown. (Combined with...) Figure 4 In some embodiments, the support assembly 220 includes a support screw 221 and a tray 222. The bottom end of the support screw 221 is threaded into a first slot 2121, and the tray 222 is connected to the top of the support screw 221 to support the flange 130 of the workpiece. Exemplarily, the diameter of the tray 222 is slightly smaller than the diameter of the flange 130, the top surface of the tray 222 is flat, and the tray 222 may be provided with a plurality of weight-reducing holes 223 spaced around the central axis of the tray 222 to reduce the cost of using the support assembly 220.

[0052] Figure 5A schematic diagram of the locking assembly 230 is shown. Figure 6 It shows Figure 3 Enlarged diagram of point A, Figure 7 It shows Figure 5 A schematic diagram of the explosion. Combined with... Figures 5-7 In some embodiments, the locking components 230 and the recesses 131 on the circumferential surface of the flange 130 are correspondingly arranged, and multiple locking components 230 are also arranged around the periphery of the support component 220. Each locking component 230 includes a locking screw 232, a slide bar 233, a reset member 234, and an expansion member 235. The locking screw 232 is threadedly connected to the corresponding second slot 2122, and the locking screw 232 is provided with a through inflation channel 2321. The slide bar 233 is slidably inserted into the inflation channel 2321 of the locking screw 232 and is spaced apart in the corresponding second slot 2122. The bottom end of the reset member 234 is connected to the slide bar 233. The top is connected to the side wall of the inflation channel 2321; the expansion member 235 is connected to the locking screw 232, and the interior of the expansion member 235 communicates with the inflation channel 2321; wherein, the slide rod 233 slides upward in the inflation channel 2321 to increase the internal pressure of the expansion member 235, causing at least a portion of the expansion member 235 to expand outward and abut against the side wall of the corresponding recess 131, and at least a portion of the expansion member 235 is configured as the inflation part 231.

[0053] In practice, before inserting the locking screw 232 into the second slot 2122, the slide bar 233 inside the locking screw 232 is positioned within the second slot 2122, and the interior of the expansion member 235 communicates with the outside through the air passage 2321 inside the locking screw 232. During the insertion of the locking screw 232 into the second slot 2122, the slide bar 233 is continuously pushed forward through the air passage 2321 to the top of the locking screw 232, expelling the air inside the locking screw 232 into the expansion member 235. The air pressure inside the expansion member 235 increases accordingly, thus initiating expansion. This causes the circumferential surface of the expansion member 235 to abut against the recess 131 on the outer wall of the flange 130, forming a stable support and positioning, effectively preventing the workpiece from shifting or loosening during the inspection process. As the air pressure continues to act, the circumferential surface of the expansion member 235 completely fits against the inner wall of the recess 131, further improving the clamping accuracy and stability. This clamping method can adapt to the clamping and inspection of various types of workpieces with disc-shaped through shafts 10. By combining multiple second slots 2122 with the locking assembly 230, it can adapt to workpieces of different sizes and structures, improving the versatility and flexibility of the device, and effectively meeting the inspection of workpieces of various specifications.

[0054] In some embodiments, the outer peripheral surface of the slide rod 233 is elastic, so that the slide rod 233 elastically contacts the inner wall of the inflation channel 2321. This ensures that during the process of the slide rod 233 being pushed into the top of the locking screw 232 within the inflation channel 2321, the outer peripheral surface of the slide rod 233 and the inner wall of the inflation channel 2321 remain in close contact, thus preventing air leakage between the outer peripheral surface of the slide rod 233 and the inner wall of the inflation channel 2321, which would cause the expansion member 235 to deflate and affect the support and clamping of the workpiece. During the process of the slide bar 233 being pushed into the top of the locking screw 232 within the inflation channel 2321, the reset member 234 is compressed and stores energy. When the locking screw 232 is removed from the corresponding second slot 2122, the slide bar 233 exits from the inflation channel 2321 of the locking screw 232 under the action of the reset member 234. Furthermore, due to the connecting effect of the reset member 234, the slide bar 233 will not separate from the locking screw 232, thereby improving the convenience of operation.

[0055] Combination Figures 5-7 In some embodiments, the expansion member 235 includes a connecting sleeve 2351 and an expansion sleeve 2352. The connecting sleeve 2351 is connected to the top of the locking screw 232, and the bottom of the expansion sleeve 2352 is fitted onto the top of the connecting sleeve 2351. The periphery of the expansion sleeve 2352 is flexible, that is, the periphery of the expansion sleeve 2352 is configured as an inflation part 231. With this configuration, the bottom of the expansion sleeve 2352 can be constrained by the connecting sleeve 2351, so that the expansion sleeve 2352 maintains its existing shape. The connecting sleeve 2351 also connects the inflation channel 2321 and the expansion sleeve 2352, so that when the slide rod 233 moves upward, air can enter the expansion sleeve 2352 from the inflation channel 2321 and the connecting sleeve 2351. The peripheral sidewall of the expansion sleeve 2352 is made of an elastic material. When gas is filled into the expansion sleeve 2352, the peripheral sidewall of the expansion sleeve 2352 expands to abut against the sidewall of the corresponding recess 131.

[0056] In other embodiments, the inflation part 231 can also be connected to an inflation device, that is, the inflation part 231 can be inflated by the inflation device to expand the inflation part 231 to abut against the inner wall of the recess 131, thereby positioning the radial displacement of the flange 130.

[0057] Furthermore, during the machining process of the through-shaft 10 with disc, metal debris can easily remain in the recess 131 of the flange 130. If this debris is not cleaned in time, it will become trapped between the inflation part 231 and the workpiece during workpiece inspection, causing wear on at least one of the clamping surfaces of the inflation part 231 and the workpiece. This not only reduces contact accuracy and friction but may also cause appearance defects in the workpiece. Based on this, this application further improves the aforementioned inspection device 20.

[0058] Combination Figures 5-7In some embodiments, the circumferential surface of the inflation part 231 has multiple grooves 2353, which extend vertically. During the process of the inflation part 231 expanding and abutting against the recess 131 of the flange 130, as the locking screw 232 rotates to insert into the corresponding second slot 2122, the inflation part 231 rotates synchronously with the locking screw 232, and the grooves 2353 on the inflation part 231 also rotate synchronously. This scrapes metal debris remaining in the recess 131 of the flange 130 into the grooves 2353. Some of the metal debris is flung out with the rotation of the grooves 2353, while other metal debris is scraped into the grooves 2353. The expansion sleeve 231 is recessed inside the workpiece and does not contact the side wall of the recess 131 of the flange 130. This ensures that when the inflation part 231 continues to expand and clamps the flange 130, there will be no residue wear between the surface of the inflation part 231 and the workpiece, thus ensuring a clean and intact clamping surface. This improves contact accuracy and friction, effectively avoiding the technical problem of appearance defects caused by debris. In addition, the multiple grooves 2353 can also increase the friction between the inflation part 231 and the farad plate, improving the clamping effect on the flange 130. In specific implementation, the multiple grooves 2353 are formed on the outer peripheral surface of the expansion sleeve 2352. When the expansion sleeve 2352 is inflated, the outer peripheral surface of the expansion sleeve 2352 forms concave grooves 2353.

[0059] Combination Figures 5-7 In some embodiments, the circumferential surface of the inflation part 231 is provided with a plurality of protrusions 2356, which are arranged in rows and columns. The spacing between two adjacent rows of protrusions 2356 is consistent with the thickness of the flange 130, and at least one row of protrusions 2356 is provided between two adjacent grooves 2353. During the rotation of the locking screw 232, the flange 130 is embedded between two protrusions 2356 as much as possible to restrict the position of the flange 130 in the axial direction and prevent the workpiece from moving axially. The protrusions 2356 cooperate with the inflation part 231 to form a double limit on the flange 130 and enhance the clamping stability. Exemplarily, the outer circumferential surface of the expansion sleeve 2352 is integrally formed with the above-mentioned protrusions 2356. The protrusions 2356 can be spherical and have a certain degree of flexibility to avoid damage to the surface of the flange 130 during the rotation of the locking screw 232.

[0060] Figure 8 It shows Figure 5 Another structural diagram from a different perspective, combined with Figure 5 as well as Figure 8To facilitate the operation of the locking screw 232, the detection device 20 provided in this application further includes an operating component 240. This operating component 240 includes an operating member 241 and a connecting rod 242. The operating member 241 has a connecting hole 243. An expansion sleeve 2352 passes through the bottom end of the connecting rod 242 and connects to the connecting sleeve 2351. The top end of the connecting rod 242 is inserted into the connecting hole 243, so that the connecting rod 242, the operating member 241, the connecting sleeve 2351, and the locking screw 232 can be relatively fixed. When the operator applies force to the operating member 241, the connecting sleeve 2351 and the locking screw 232 will rotate synchronously.

[0061] In some embodiments, the tops of the connecting hole 243 and the connecting rod 242 are non-circular and mutually engaging. With this configuration, when the connecting rod 242 is fitted into the connecting hole 243 of the operating member 241, the connecting rod 242 and the operating member 241 are relatively fixed. Controlling the rotation of the operating member 241 will drive the connecting rod 242 to rotate synchronously. If the operating member 241 obstructs the workpiece during inspection, it can be quickly removed from the top of the connecting rod 242 to facilitate comprehensive inspection of the through shaft 10. Exemplarily, the operating member 241 is disc-shaped, with multiple recesses 244 spaced apart around its periphery to facilitate force application by the operator. The connecting hole 243 located in the center of the operating member 241 can be square, and correspondingly, the top of the connecting rod 242 is also square. In other embodiments, the connecting hole 243 in the center of the operating member 241 and the top of the connecting rod 242 can also be elliptical, polygonal, etc., and this application does not impose any limitations on this.

[0062] In related technologies, during the operation of the locking screw 232, it is difficult for the operator to intuitively perceive changes in clamping force. When rotating the operating component 240, the operator cannot accurately determine when the appropriate clamping force has been reached, which may lead to insufficient clamping force on the flange 130 after the inflation part 231 expands, resulting in the workpiece becoming loose on the worktable 211. Based on this, this application further improves the aforementioned detection device 20.

[0063] Figure 9 A structural schematic diagram of the expansion member 235 is shown. (Combined with...) Figure 9 In some embodiments, the bottom of the expansion member 235 is provided with a groove 2354, the opening of the groove 2354 faces downward, and the bottom of the groove 2354 is provided with a vent 2355. Figure 10 It shows Figure 7 Enlarged diagram of point B, Figure 11 An exploded view of the auxiliary component 250 is shown. (Combined with...) Figures 10-11The detection device 20 also includes an auxiliary component 250, which includes a sealing ring 251, which is fitted onto the locking screw 232 and located below the expansion member 235. The sealing ring 251 can be adapted to pass through the slide groove 2354. When clamping flanges 130 of different diameters, the locking screw 232 rotates into the second slot 2122 to different depths, and clamping is completed by the expansion member 235 with different degrees of expansion. When a tighter clamping is required for the flange 130, the locking screw 232 needs to be inserted deeper into the second slot 2122, so that the slide rod 233 is pushed into the air channel 2321 in the locking screw 232 to a deeper depth, thereby squeezing more air into the expansion member 235. At this time, as the locking screw 232 descends to a deeper depth, thus... The sealing ring 251 below the expansion member 235 abuts against the top surface of the worktable 211. As the expansion member 235 continues to descend, the sealing ring 251 is pushed into the sliding groove 2354 at the bottom of the expansion member 235. Since the sealing ring 251 has a large volume, more air is pushed into the expansion member 235 by the sealing ring 251. Thus, when the expansion sleeve 2352 needs to clamp more tightly, more air is pushed into the expansion member 235 by the lifting ring to further compensate for the insufficient expansion of the expansion member 235, thereby achieving stable clamping of large-diameter workpieces. In addition, when the locking screw 232 is rotated and lowered, when the sealing ring 251 abuts against the top surface of the worktable 211, if the locking screw 232 is rotated further, the sealing ring 251 can provide greater pressure when it enters the slide groove 2354, causing the resistance to the descent of the locking screw 232 to increase rapidly. The operator can immediately feel the depth of the locking screw 232 in the second slot 2122 through their body, and thus know the degree of expansion of the expansion component 235. This enables precise perception and control of the clamping force, improving the intuitiveness and safety of the operation.

[0064] Combination Figures 10-11 In specific implementation, the groove 2354 is opened at the bottom of the connecting sleeve 2351. The depth of the groove 2354 is greater than the axial length of the sealing ring 251. At the same time, the sealing ring 251 is also elastic, so that the sealing ring 251 and the side wall of the groove 2354 are in elastic contact. When the sealing ring 251 is located in the groove 2354, the two remain sealed to prevent air from leaking from the gap between them.

[0065] Combination Figures 10-11 In some embodiments, the auxiliary structure further includes a limiting ring 252, which is gapped on the locking screw 232 and connected to the bottom of the sealing ring 251. The limiting ring 252 can abut against the bottom of the expansion member 235 to limit the depth of the sealing ring 251 inserted into the groove 2354.

[0066] Combination Figures 10-11In some embodiments, the auxiliary structure further includes a flexible element 253, which is connected to the limiting ring 252 and suspended on the expansion member 235. This arrangement ensures that the sealing ring 251 and the limiting ring 252 are always suspended on the expansion member 235, facilitating operation. For example, multiple flexible elements 253 are provided, with their top ends connected to the bottom of the connecting sleeve 2351 located outside the opening side of the slide groove 2354, and their bottom ends connected to the limiting ring 252.

[0067] In summary, the integrated testing device 20 for the through-shaft 10 with disc provided in this application can conveniently and quickly lock the through-shaft 10 with disc onto the worktable 211. Through the inflation part 231, it can adapt to clamping and locking flanges 130 of different diameters. Furthermore, the groove 2353 on the inflation part 231 can clean residues in the recess 131 of the flange 130, ensuring the inflation part 231 and the flange 130 are clean and intact. The auxiliary component 250 can also push more air into the expansion member 235, preventing insufficient expansion of the expansion member 235 from causing loosening of the flange 130. Moreover, the operator can immediately and clearly feel the depth of the threaded slot 212 through their body, thus determining the degree of expansion of the expansion sleeve 2352, achieving precise perception and control of the clamping force, and improving the intuitiveness of the operation.
