[0056] Reference Figures 1 to 3As shown in Figures 5 to 9, the present invention provides a technical solution: an input shaft final inspection machine, comprising a machine platform 10, a transfer device 20 and a compliance detection device 30, the machine platform 10 having a working panel 11; the transfer device 20 is arranged on the working panel 11, the transfer device 20 comprises a moving mechanism 21 and a fixture 22, the fixture 22 is arranged at the output end of the moving mechanism 21; the compliance detection device 30 is arranged opposite to the transfer device 20, the compliance detection device 30 comprises a notch measurement mechanism 31 and a base 32, the notch measurement mechanism 31 comprises a dual-axis moving platform 311, a cross plate 312 and a notch measurement component 313, the cross plate 312 is arranged at the output end of the dual-axis moving platform 311, the notch measurement component 313 comprises a set gauge 3131, a third linear drive member 3132 and a plug gauge 3133, the sleeve gauge 3131 is connected to the end of the cross plate 312 away from the dual-axis movable platform 311, the sleeve gauge 3131 is provided with a first through hole 31311 extending along the first direction and a second through hole 31312 extending along the second direction, the second through hole 31312 is communicated with the first through hole 31311, the third linear drive member 3132 is arranged on the sleeve gauge 3131, and the output end of the third linear drive member 3132 is arranged opposite to the second through hole 31312, one end of the plug gauge 3133 is connected to the output end of the third linear drive member 3132, the base 32 is arranged opposite to the sleeve gauge 3131, and the base 32 is provided with a first accommodating hole extending along the first direction.

[0057] Exemplarily, the moving mechanism 21 may be a three-axis moving platform or a manipulator, etc. When the plug gauge 3133 is assembled, the other end of the plug gauge 3133 may be exposed outside the second through hole 31312 , or the other end of the plug gauge 3133 may be inserted into the second through hole 31312 and not pass through the first through hole 31311 temporarily.

[0058] According to this embodiment, during the transfer of the input shaft 1, the dual-axis mobile platform 311 drives the notch measurement assembly 313 to move away from the base 32, so that moving space can be reserved for the fixture 22. The fixture 22 clamps the first section 2, and then moves by the moving mechanism 21 to transfer the input shaft 1 to the first receiving hole, so that a part of the second section 5 is inserted into the first receiving hole. At this time, the dual-axis mobile platform 311 drives the notch measurement assembly 313 to move toward the base 32, so that the sleeve gauge 3131 corresponds to the base 32. During the measurement of the semi-lunar notch 3, the dual-axis mobile platform 311 drives the cross plate 312 and the notch measurement assembly 313 to move toward the first section 2, and inserts the first section 2 into the first through hole 31311. Then, the third linear drive member 3132 pushes the other end of the plug gauge 3133 to move in the second through hole 31312, and can measure whether the diameter of the semi-lunar notch 3 is compliant. When the plug gauge 3133 successfully passes through the semi-crescent notch 3, it indicates that the diameter of the semi-crescent notch 3 is compliant; when the plug gauge 3133 cannot pass through the semi-crescent notch 3, it indicates that the diameter of the semi-crescent notch 3 is not compliant; that is, the diameter of the semi-crescent notch 3 is too small.

[0059] Reference Figure 4 As shown, in some embodiments, the clamp 22 includes a first rotary driving member 221, a connecting plate 222 and a finger clamp 223, the connecting plate 222 is connected to the output end of the first rotary driving member 221, and there is at least one finger clamp 223, at least one of the finger clamps 223 is connected to the side of the connecting plate 222 away from the first rotary driving member 221.

[0060] Exemplarily, the finger gripper 223 may be a pneumatic gripper or an electric gripper, etc.

[0061] According to this embodiment, the first rotating driving member 221 can drive the rotating connecting plate 222 to drive the finger clamp 223 to rotate. When there is one finger clamp 223, the direction of the half-moon notch 3 can be adjusted by rotating the finger clamp 223 during the process of placing the input shaft 1. When there are multiple finger clamps 223, the position of each input shaft 1 can be adjusted by rotating the finger clamp 223 during the process of clamping or placing the input shaft 1.

[0062] Reference Figures 5 and 6 As shown, in some embodiments, the dual-axis movable platform 311 includes a first linear driving member 3111, a first support seat 3112 and a second linear driving member 3113, the first support seat 3112 is connected to the output end of the first linear driving member 3111, the second linear driving member 3113 is arranged on the first support seat 3112, and the other end of the horizontal plate 312 is connected to the output end of the second linear driving member 3113.

[0063] According to this embodiment, the first linear drive 3111 provides power to move the notch measurement assembly 313 toward or away from the base 32 ; the second linear drive 3113 provides power to move the sleeve gauge 3131 toward or away from the base 32 .

[0064] Reference Figures 5 and 6 As shown, in some embodiments, the notch measurement mechanism 31 includes a self-centering floating platform 314 , which is disposed between an end of the transverse plate 312 away from the dual-axis movable platform 311 and the sleeve gauge 3131 .

[0065] According to this embodiment, when the first section 2 is about to be inserted into the first through hole 31311, the first section 2 and the first through hole 31311 may not be coaxial. Therefore, in this process, through the floating effect of the self-centering floating platform 314, when the first section 2 is inserted into the first through hole 31311, the sleeve gauge 3131 is affected by the force of the first section 2 and drives the self-centering floating platform 314 to make fine adjustments, ensuring that the first section 2 can be smoothly inserted into the first through hole 31311.

[0066] Reference Figure 5 and 10 As shown, in some embodiments, the base 32 includes a shell 321, a first connecting tube 3211 and a jacket 322, the first accommodating hole is formed on the shell 321, the first connecting tube 3211 is at least a pair, in a pair of the first connecting tubes 3211, one first connecting tube 3211 is used as a ventilation pipe, and the other first connecting tube 3211 is used as an exhaust pipe, at least one pair of the first connecting tubes 3211 is arranged on the shell 321, at least one pair of the first connecting tubes 3211 is connected to the inner cavity of the shell 321, and the bottom end of the jacket 322 is arranged in the first accommodating hole.

[0067] Exemplarily, the ventilation pipe is connected to an external air supply device via a conduit, and the exhaust pipe is connected to an external air extraction device via a conduit.

[0068] According to this embodiment, after the input shaft 1 is placed in the first receiving hole, an external gas supply device supplies gas to the housing 321 via the vent pipe. After the gas fills the housing 321, the gas exerts an extrusion force on the jacket 322, causing the jacket 322 to clamp the second section 5, thereby preventing the input shaft 1 from tilting. After the measurement of the input shaft 1 is completed, the external air extraction device evacuates the air in the housing 321 via the exhaust pipe, causing the jacket 322 to release the input shaft 1, thereby facilitating the removal of the input shaft 1.

[0069] Reference Fig.11 As shown, in some embodiments, a plurality of long grooves 3221 are formed on the jacket 322 , and all the long grooves 3221 are arranged at intervals around the axis of the jacket 322 .

[0070] According to this embodiment, the hardness of the jacket 322 can be reduced, making it easier for the jacket 322 to deform when it is affected by the extrusion force.

[0071] Reference Figure 2 and 5 As shown, in some embodiments, the notch measurement mechanism 31 includes a visual measurement component 33, and the visual measurement component 33 includes a second support base 331 and a camera 332, wherein the second support base 331 is disposed between the dual-axis movable platform 311 and the base 32, and there is at least one camera 332, and at least one camera 332 is disposed on a side of the second support base 331 away from the dual-axis movable platform 311.

[0072] For example, the camera 332 may be electrically connected to a computer or the like.

[0073] According to this embodiment, just after the input shaft 1 is placed in the first receiving hole or after the diameter of the semi-crescent notch 3 is measured in compliance, the camera 332 takes a picture of the first section 2 and cooperates with the computer to obtain the diameter of the first section 2 and the thickness of the flat part 4.

[0074] Reference Figure 5 As shown, in some embodiments, the machine 10 has a accommodating cavity, the notch measuring mechanism 31 includes a rotating component 34, the rotating component 34 is disposed in the accommodating cavity, and the rotating component 34 is disposed corresponding to the shell 321, the rotating component 34 includes a third support seat 341 and a second rotating driving member 342, the third support seat 341 is connected to the working panel 11, the second rotating driving member 342 is disposed on the third support seat 341, and the output end of the second rotating driving member 342 sequentially passes through the third support seat 341 and the working panel 11 and is connected to the shell 321.

[0075] According to this embodiment, when the input shaft 1 is placed in the first receiving hole, the flat part 4 is used as a reference surface, and the camera 332 and the computer cooperate to identify the direction of the half-moon notch 3 and determine whether the input shaft 1 is aligned. If the direction of the half-moon notch 3 and / or the input shaft 1 is not aligned, the second rotating driving member 342 drives the base 32 to rotate, and the direction of the half-moon notch 3 can be adjusted to a preset direction and / or the input shaft 1 can be adjusted to a correct angle.

[0076] Reference Figure 2 and 12As shown, in some embodiments, an outer diameter measuring device 40 is included, and the outer diameter measuring device 40 is arranged opposite to the base 32. The outer diameter measuring device 40 includes an outer diameter pneumatic probe 41. The outer diameter pneumatic probe 41 is provided with a second accommodating hole 411 extending along the first direction, and the second accommodating hole 411 is a blind hole. The outer diameter pneumatic probe 41 is provided with a second connecting tube 412, and the second connecting tube 412 is connected to the second accommodating hole 411.

[0077] Exemplarily, the second connecting tube 412 is connected to the air supply end of the pneumatic measuring instrument via a conduit.

[0078] According to this embodiment, when the input shaft 1 is transferred to the second receiving hole 411 by the moving device, the pneumatic measuring instrument supplies gas to the second receiving hole 411. The pneumatic measuring instrument detects that the pressure of the gas in the second receiving hole 411 changes and obtains the actual pressure; then, the pneumatic measuring instrument calculates using the reference pressure and the actual pressure, thereby measuring the outer diameter of the second section 5.

[0079] Reference Figure 2 and 13 As shown, in some embodiments, an inner diameter measuring device 50 is included, and the inner diameter measuring device 50 is arranged opposite to the outer diameter measuring device 40. The working panel 11 is provided with the third through hole corresponding to the inner diameter measuring device 50, and the third through hole is communicated with the accommodating cavity. A part of the inner diameter measuring device 50 passes through the third through hole and extends into the accommodating cavity. The inner diameter measuring device 50 includes a fifth support seat 51, a connecting rod clamp 52, a sixth support seat 53, and a linear drive mechanism 54. , a bushing 55, a fixing plate 56 and an inner diameter pneumatic probe 57, the connecting rod clamp 52, the sixth support seat 53 and the linear drive mechanism 54 are all arranged on the fifth support seat 51, the connecting rod clamp 52, the sixth support seat 53 and the linear drive mechanism 54 are arranged in sequence along the first direction, the bushing 55 is arranged on the sixth support seat 53, the fixing plate 56 is connected to the output end of the linear drive mechanism 54, and the inner diameter pneumatic probe 57 is arranged on the fixing plate 56.

[0080] For example, the linear drive mechanism 54 may be a linear module, a cylinder, a hydraulic cylinder or an electric push rod, etc. The inner diameter pneumatic probe 57 is connected to the air supply end of the pneumatic measuring instrument via a conduit.

[0081] According to this embodiment, after the second end is inserted into the bushing 55, the connecting rod clamp 52 presses the first section 2. Then, the linear drive mechanism 54 pushes the fixing plate 56 to move toward the sixth support seat 53, and the inner diameter pneumatic probe 57 is inserted into the inner hole of the input shaft 1 to measure the inner diameter of the inner hole.

[0082] It should be noted that the measuring principle of the inner diameter of the inner hole is the same as the measuring principle of the outer diameter of the second section 5 mentioned above, and the measuring principle of the inner diameter of the inner hole will not be described in detail here.

[0083] It is worth noting that the number of inner diameter measuring devices 50 is set according to the number of inner holes to be measured in the input shaft 1; and for the size of the inner hole, it is only necessary to replace the inner diameter pneumatic measuring heads 57 of different specifications, so the number of inner diameter measuring devices 50 is not further limited here. For example, in the present invention, the input shaft 1 has a first inner hole 6 and a second inner hole 7, so two inner diameter measuring devices 50 can be set, and the two inner diameter measuring devices 50 use inner diameter pneumatic measuring heads 57 of different specifications.

[0084] Reference Figure 2 and 14 As shown, in some embodiments, a code reading device 60 is included. The code reading device 60 includes a laser code reader 61 . The laser code reader 61 is arranged opposite to the outer diameter measuring device 40 .

[0085] Exemplarily, the laser code reader 61 may be electrically connected to a computer or the like.

[0086] According to this embodiment, after all measurement items of the input shaft 1 are measured, the transfer device 20 transfers the input shaft 1 to the second receiving hole 411 and reads the code through the laser code reader 61, so that the computer can score and grade the quality of the current input shaft 1 and archive it.

[0087] Reference Figure 2 and 14 As shown, in some embodiments, the code reading device 60 includes an optical bench 62 and a fifth linear drive member 63. The optical bench 62 is arranged corresponding to the laser code reader 61. A refractor 621 is provided on the optical bench 62. The laser emitting end face of the laser code reader 61 faces the refractor 621. The output end of the fifth linear drive member 63 is connected to the laser code reader 61.

[0088] Exemplarily, the laser code reader 61 may be a code reader of the SR-X series produced by Keyence (China) Co., Ltd. The specific model is selected according to the barcode or QR code, and will not be described in detail here.

[0089] According to this embodiment, when reading the barcode on the input shaft 1, the refractor 621 refracts the barcode or the two-dimensional code to the laser code reader 61, so that the laser code reader 61 can read it.
