Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.
[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0026] like Figures 1 to 3 As shown, at least one embodiment provides a short shaft full inspection machine, which includes: a posture adjustment station 1, used to receive the short shaft 5 and adjust it to a desired posture by rotation; a measuring station 2, used to receive the short shaft 5 after the posture is adjusted, and obtain the outer diameter data and the hole distance data of the short shaft 5 through the outer diameter measuring component 21 and the hole distance measuring component 22 respectively; a marking station 3, used to receive the short shaft 5 and mark the qualified short shaft 5; and a transfer mechanism 4, which is electrically connected to the control module; wherein the control module is configured to control the transfer mechanism 4 to transport the short shaft 5, so that it passes through the posture adjustment station 1, the outer diameter measuring component 21, the hole distance measuring component 22 and the marking station 3 in sequence.
[0027] In this embodiment, the postures of the short shafts 5 received by the posture adjustment station 1 are different, and their postures need to be adjusted to achieve unification, so that the subsequent measuring station 2 can measure their dimensional data; at the same time, the transfer mechanism 4 has four clamps, and the four clamps respectively grasp the short shafts 5 placed on the posture adjustment station 1, the outer diameter measuring component 21, the hole spacing measuring component 22 and the marking station 3, and transport the corresponding short shafts 5 to the next station, thereby realizing fast and continuous transportation.
[0028] like Figure 4 As shown, in some embodiments, the posture adjustment station 1 includes: a pair of rollers 11 arranged in parallel, with a gap between the two rollers 11 to receive the short shaft 5; a driver 12, connected to the two rollers 11; and a first sensor 13, for acquiring and sending the position data of the milling surface 51 of the short shaft 5; wherein the control module is configured to control the driver 12 to drive the two rollers 11 to rotate in the same direction and synchronously, so that the short shaft 5 rotates to adjust the position of the milling surface 51, and control the driver 12 to stop when the milling surface 51 rotates to the desired position.
[0029] In this embodiment, the short shaft 5 rolls down between the two rollers 11. The posture of the short shaft 5 at this time is not necessarily the desired posture. The driver 12 drives the two rollers 11 to rotate in the same direction and synchronously to make the short shaft 5 rotate until the milling surface 51 faces upward; wherein the first sensor 13 can be a photoelectric sensor. Since there is a through hole 52 on the short shaft 5, when the short shaft 5 rotates to the point where the signal generated by the transmitting end of the photoelectric sensor can pass through the through hole 52 to the receiving end, the posture of the short shaft 5 is in place.
[0030] like Figure 4 As shown, in some embodiments, the posture adjustment station 1 also includes: a push rod 14; the push rod 14 is located on one side of the roller 11, and its axis is coaxial with the axis of the short shaft 5; the control module is configured to control the push rod 14 to push the short shaft 5 along the roller 11 to the grabbing position 41 when the milling surface 51 rotates to the desired position, and then control the transfer mechanism 4 to move the short shaft 5 in the grabbing position 41 to the outer diameter measuring component 21.
[0031] In this embodiment, when the posture of the short shaft 5 is adjusted to the desired position, the driver 12 stops working, and then the short shaft 5 is pushed to the gripping position 41 by the push rod 14 to wait for being transported to the measuring station 2 for dimensional measurement.

[0033] In this embodiment, the first limiting base 211 is used to receive the short shaft 5 transported by the transfer mechanism 4 from the grabbing position 41, and then the short shaft 5 is limited by closing the first clamping tool 212, so that the subsequent second sensor can measure the diameter of the short shaft 5; wherein the second sensor can use a pneumatic measuring instrument.
[0034] like Figure 5 As shown, in some embodiments, the hole distance measurement assembly 22 includes: a second limit base 221, a second clamping fixture 222, a hole positioning fixture 223, an end limit fixture 224 and a third sensor 225; wherein the control module is configured to control the second clamping fixture 222 and the hole positioning fixture 223 to close synchronously to respectively tighten the side wall of the short shaft 5 and insert the through hole 52 of the side wall of the short shaft 5, and then control the end limit fixture 224 to press against the end face of the short shaft 5, and obtain the forward movement distance of the end limit fixture 224 through the third sensor 225; the control module is also configured to control the transfer mechanism 4 to transport the short shaft 5 after the hole distance measurement is completed from the second limit base 221 to the marking station 3.
[0035] In this embodiment, the second limiting base 221 is used to receive the short shaft 5 transported from the first limiting base 211 by the transfer mechanism 4, and then inserted into the through hole 52 through the closure of the hole positioning tooling 223 to position the position of the short shaft 5, and at the same time, the short shaft 5 is limited by the closure of the second clamping tooling 222 to prevent tilting, and finally, it is moved toward the end face of the short shaft 5 through the end limiting tooling 224 until it is against it, and the distance from the end face of the short shaft 5 to the through hole 52 is measured by the displacement data obtained by the third sensor 225; wherein the third sensor 225 adopts a displacement sensor, and optionally, a coordinate system is established, and the position data of the through hole 52 and the initial position data of the end limiting tooling 224 are known in advance, and the distance from the through hole 52 to the end face is converted by obtaining the forward movement distance of the end limiting tooling 224.
[0036] In some embodiments, the control module is configured to control the second clamping tool 222 and the hole positioning tool 223 to open and close twice synchronously, so that the hole positioning tool 223 can be accurately inserted into the through hole 52 of the short shaft 5 .
[0037] In this embodiment, the opening and closing are performed twice in order to precisely insert the hole positioning tool 223 into the through hole 52 .
[0038] like Figure 4 As shown, in some embodiments, the marking station 3 includes: a third limiting base 31, a third clamping tool 32 and a marker 33; wherein the control module is configured to control the third clamping tool 32 to close to tighten the short shaft 5 on the third limiting base 31, and then control the marker 33 to mark the short shaft 5.
[0039] In this embodiment, the third limiting base 31 is used to receive the short shaft 5 transported by the transfer mechanism 4 from the second limiting base 221, and then the short shaft 5 is limited by closing the third clamping tool 32 to prevent tilting, and finally the end face of the short shaft 5 is marked by the marker 33.
[0040] In some embodiments, a guide plate 15 is disposed on one side of the roller 11 ; a plurality of short shafts 5 are received on the guide plate 15 to be replaced after the push rod 14 pushes away the short shafts 5 whose postures have been adjusted.
[0041] In some embodiments, the control module can but is not limited to using PLC; the working process of the short shaft full inspection machine includes: controlling the driver 12 through the control module to drive the roller 11 to rotate to adjust the posture of the short shaft 5; controlling the transfer mechanism 4 through the control module to transport the short shaft 5 to the measuring station 2; controlling the sensor on the measuring station 2 to measure the outer diameter data and hole spacing data of the short shaft 5 through the control module; controlling the transfer mechanism 4 through the control module to transport the short shaft 5 from the measuring station 2 to the marking station 3; controlling the marking station 3 to mark the short shaft 5 through the control module.
[0042] At least one embodiment also provides a working method of a short shaft full inspection machine, which includes: adjusting the short shaft 5 to a desired posture through the posture adjustment station 1; obtaining the outer diameter data of the short shaft 5 through the outer diameter measuring component 21 of the measuring station 2; obtaining the hole spacing data of the short shaft 5 through the hole spacing measuring component 22 of the measuring station 2; marking the short shaft 5 through the marking station 3; and transporting the short shaft 5 through the transfer mechanism 4 so that it passes through the posture adjustment station 1, the outer diameter measuring component 21, the hole spacing measuring component 22 and the marking station 3 in sequence.

[0044] For the specific structure and implementation process of the short-axis full inspection machine, please refer to the relevant discussion in the above embodiments, which will not be repeated here.
[0045] In summary, the short shaft full inspection machine and its working method have different postures for the short shafts 5 received by the posture adjustment station 1, and need to adjust their postures to achieve unification, so as to facilitate the subsequent measurement station 2 to measure their dimensional data; at the same time, the transfer mechanism 4 has four clamps, which respectively grab the short shafts 5 placed on the posture adjustment station 1, the outer diameter measuring component 21, the hole spacing measuring component 22 and the marking station 3, and transport the corresponding short shafts 5 to the next station, thereby realizing fast and continuous transportation.
