Detailed implementation manners

[0018] The following further elaborates on the detailed implementation manners of this invention with reference to the accompanying drawings.

[0019] Refer to Figure 1 、 Figure 2The present invention provides an automatic detection device for the quenching state of a real shaft, including a detection mechanism 6, which is used to detect the real shaft to obtain surface features, including a shell 1, a feed port and a discharge port are respectively arranged on the front and back of the shell 1, the bottom of the shell 1 is arranged as a sorting opening, and a plurality of oblique support contact feet 2 penetrating into the interior are respectively arranged on both sides of the shell 1, a top support contact foot 3 penetrating into the interior is fixedly connected to the top of the shell 1, a collecting box seat 5 is docked at the sorting opening at the bottom of the shell 1, and a moving drive mechanism 4 is fixedly installed on both sides of the shell 1, and the output ends of the two moving drive mechanisms 4 are respectively docked with a plurality of oblique support contact feet 2 on both sides of the shell 1, and two detection mechanisms 6 are provided and fixedly installed on both sides of the inner wall of the shell 1, and the two detection mechanisms 6 are respectively arranged at the gap between the top support contact foot 3 and the oblique support contact feet 2 on both sides; A plurality of top support contact pins 3 on the top of the housing 1 and a plurality of oblique support contact pins 2 on both sides of the housing 1 cooperate to locate the real axis; The oblique support contact pin 2 is used to drive the real shaft to rotate, and the top support contact pin 3 is used to drive the real shaft to move along the axial direction; The driving mechanism 4 is used to control the displacement of the diagonal support contact foot 2 to make the real shaft fall for sorting.

[0020] When in use, the real shaft to be detected can be input from the feed port of the shell 1 through a manipulator or a transmission drive, and the real shaft entering the shell 1 is supported by a plurality of top support touch feet 3 and a plurality of oblique support touch feet 2 on both sides. The operation of the plurality of top support touch feet 3 can drive the real shaft to move along the axial direction until it reaches the middle position of the shell 1, and the operation of the plurality of oblique support touch feet 2 can make the real shaft rotate. In this process, the surface characteristics of the real shaft are detected by the detection mechanism 6 to detect the quenching state. Since the real shaft can rotate, the detection mechanism 6 can perform all-round detection of the real shaft to avoid the occurrence of a detection blind spot. After completion, the qualified real shaft is displaced along the axial direction by the top support touch feet 3 and discharged from the discharge port of the shell 1. After discharge, the real shaft can be connected to the next processing step through a manipulator or a conveyor belt. For the unqualified real shaft after quenching, the two moving drive mechanisms 4 are operated to drive the plurality of oblique support touch feet 2 on both sides of the shell 1 to move and increase the spacing. At this time, the unqualified real shaft loses the bottom support effect, falls under the action of gravity, and is collected by the collection box seat 5 to achieve the sorting effect.

[0021] Reference Figure 3 The driving mechanism 4 includes a connecting arm 41, a motor 42, and a threaded rod 43. The connecting arm 41 is fixedly connected to a plurality of diagonal support contact feet 2 on one side of the shell 1. The motor 42 is fixedly installed on one side of the shell 1. The connecting arm 41 is threadedly sleeved on the side wall of the threaded rod 43. The output shaft of the motor 42 is fixedly connected to the end face of the threaded rod 43. Positioning rods 44 are slidably sleeved on both sides of the connecting arm 41, and one end of the two positioning rods 44 is fixedly connected on one side of the shell 1.

[0022] When in use, the motor 42 is operated to drive the threaded rod 43 to rotate, and the connecting arm 41 is displaced under the action of the threaded structure. Since the connecting arm 41 is connected to the diagonal support contact foot 2, the driving mechanism 4 drives the diagonal support contact foot 2 to displace. By setting two driving mechanisms 4, the stability of the connecting arm 41 during movement can be improved.

[0023] Reference Figure 4 The collecting box seat 5 includes a box seat body 51, the top of the box seat body 51 is set as a feeding opening, a plurality of built-in wheels 52 are movably sleeved inside the box seat body 51, one end of the plurality of built-in wheels 52 passes through one side of the box seat body 51 and is connected for transmission through a plurality of pulley transmission assemblies 53, a motor 2 54 is fixedly installed on the other side of the box seat body 51, the output end of the motor 2 54 passes through the box seat body 51 and is connected to the other end of the built-in wheel 52, and a discharging opening is opened on the back of the box seat body 51.

[0024] Unqualified solid shafts enter through the feed opening at the top of the box seat body 51, are supported by a plurality of built-in wheels 52, and the built-in wheels 52 are driven to rotate by the output power of the motor 2 54, so that qualified solid shafts can be discharged from the discharge opening of the box seat body 51, so that the collection box seat 5 has a collection and conveying effect.

[0025] Reference Figure 5 The oblique support contact foot 2 includes a cylinder shell 21, one end of the cylinder shell 21 is fixedly connected to a support cylinder 22, one end of the support cylinder 22 is installed with a ball contact assembly 23, the support cylinder 22 is provided inside the support cylinder 22, and a push-pull assembly 24 and a rotary drive assembly 25 are provided inside the cylinder shell 21. The output ends of the push-pull assembly 24 and the rotary drive assembly 25 are connected to the caster assembly 26. The rotary drive assembly 25 is used to control the rotation of the caster assembly 26, and the push-pull assembly 24 is used to control the displacement of the caster assembly 26. The structure of the top support contact foot 3 is the same as that of the oblique support contact foot 2.

[0026] When the diagonal support contact foot 2 needs to be operated to control the rotation of the real shaft, the process first drives the caster of the caster assembly 26 to contact the ball contact assembly 23 through the operation of the push-pull assembly 24, and then the caster of the caster assembly 26 is rotated through the operation of the rotary drive assembly 25. Under the action of friction, the ball of the ball contact assembly 23 can be driven to rotate, and the friction between the ball of the ball contact assembly 23 and the real shaft can achieve the effect of driving the real shaft to rotate. Through this structural setting, when the top support contact foot 3 drives the axial displacement of the real shaft, the rotation of the ball of the ball contact assembly 23 of the diagonal support contact foot 2 can avoid the diagonal support contact foot 2 from causing a large friction resistance to the displacement of the real shaft. Since the top support contact foot 3 has the same structure as the diagonal support contact foot 2, it can achieve the axial displacement of the real shaft by installing it at a specific angle. Similarly, it can also prevent the top support contact foot 3 from causing a large friction resistance to the rotation of the real shaft.

[0027] Reference Figure 6, the push-pull assembly 24 includes an electric cylinder 241. The electric cylinder 241 is fixedly installed inside the cylinder shell 21. The output end of the electric cylinder 241 penetrates to the outside of the cylinder shell 21 and is connected with a connecting piece 242. A strip-shaped through groove is formed in the side wall of the support cylinder 22. The connecting piece 242 passes through the strip-shaped through groove and is connected with a U-shaped frame 243. One side of the U-shaped frame 243 is fixedly connected with the caster assembly 26. The output end of the rotation drive assembly 25 penetrates through the U-shaped frame 243 and docks with the caster assembly 26.

[0028] The output of the electric cylinder 241 can drive the displacement of the U-shaped frame 243 under the connection effect of the connecting piece 242. Due to the connection relationship between the U-shaped frame 243 and the caster assembly 26, the push-pull assembly 24 drives the displacement of the caster assembly 26 during transportation.

[0029] Refer to Figure 6 , a positioning rail box 244 is arranged at the bottom of the U-shaped frame 243. The positioning rail box 244 is fixedly connected to the inner wall of the support cylinder 22. A T-shaped slider is slidably sleeved in the positioning rail box 244. The T-shaped slider is fixedly connected to the bottom of the U-shaped frame 243.

[0030] By setting the positioning rail box 244 and the T-shaped slider, the stability of the U-shaped frame 243 during movement is improved.

[0031] Refer to Figure 7 , the caster assembly 26 includes a wheel frame 261. A caster main body 262 is rotatably sleeved on the inner wall of the wheel frame 261. One end of the caster main body 262 penetrates to one side of the wheel frame 261 and is connected with a passive pulley 263. A driving pulley 264 is rotatably sleeved on one side of the wheel frame 261 facing the output end of the rotation drive assembly 25. A guiding pulley 266 is fixedly connected to one side of the wheel frame 261. The passive pulley 263 is in transmission connection with the driving pulley 264 through a transmission belt 265. The transmission belt 265 bypasses the guiding pulley 266. The output end of the rotation drive assembly 25 is connected with the driving pulley 264.

[0032] Since the rotation drive assembly 25 is the rotation power mechanism of the caster assembly 26, and its position setting is different from that of the traditional caster power mechanism. By setting the passive pulley 263, the driving pulley 264, and the transmission belt 265 for rotational force transmission, the operation of the rotation drive assembly 25 controls the operation of the caster assembly 26. By setting the guiding pulley 266, the friction loss between the transmission belt 265 and the wheel frame 261 is avoided.

[0033] Refer to Figure 8 , the rotation drive assembly 25 includes a motor three 251. The motor three 251 is fixedly installed inside the cylinder shell 21. The output shaft of the motor three 251 penetrates into the support cylinder 22 and is connected with a telescopic rod 252. The telescopic rod 252 penetrates through the U-shaped frame 243 and docks with the caster assembly 26.

[0034] The telescopic rod 252 is rotated by controlling the operation of the motor three 251, and the rotational driving force is output to the caster assembly 26 through the telescopic rod 252. Since the caster assembly 26 can be displaced, by setting the telescopic rod 252, the displacement of the caster assembly 26 can be prevented from being interfered by the rotary drive assembly 25.

[0035] Referring to Figure 8 , the telescopic rod 252 includes an outer cylinder 253, and an inner sliding column 254 is slidably sleeved in the inner cavity of the outer cylinder 253. The inner sliding column 254 is a polygonal column, and the shape of the inner cavity of the outer cylinder 253 fits the inner sliding column 254.

[0036] By setting this structure, the telescopic rod 252 is prevented from rotating automatically and unable to transmit torque.

[0037] Referring to Figure 9 , the ball contact component 23 includes an end block 231. A ball main body 232 is rotatably sleeved in the inner cavity of the end block 231. The ball main body 232 protrudes from both ends of the end block 231. The end block 231 is slidably sleeved on the inner wall of the support cylinder 22. A reverse push frame 221 is fixedly connected to the inner wall of the support cylinder 22. One end of the end block 231 is drivingly connected to the reverse push frame 221 through a spring 234. A plurality of positioning chutes penetrating into the inner cavity are provided on the circumferential side of the support cylinder 22. A plurality of anti - detachment blocks 233 are provided on the circumferential side of the end block 231, and the plurality of anti - detachment blocks 233 are respectively slidably sleeved in the plurality of positioning chutes.

[0038] Due to the diameter difference at some positions on the real axis, through the structural setting of the ball contact component 23, it has an automatic position adjustment effect. When the ball contact component 23 reaches the position with a larger diameter of the real axis, the end block 231 of the ball contact component 23 is indented into the support cylinder 22 under the extrusion force. When the ball contact component 23 reaches the position with a smaller diameter of the real axis, the end block 231 is extended outwards from the inside of the support cylinder 22 by the elastic force of the spring 234 to ensure the contact between the ball contact component 23 and the real axis.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited by the above - mentioned embodiments. What is described in the above - mentioned embodiments and the specification only illustrates the principles of the present invention.
