Quenching treatment is a key process to improve the hardness and wear resistance of the real shaft. Its quality is directly related to the final quality of the real shaft. However, there are often problems such as uneven quenching, insufficient quenching depth or excessive quenching during the quenching process.

DETAILED DESCRIPTION

[0033] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Reference 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 and obtain surface features. The detection mechanism 6 includes a shell 1, a feed port and a discharge port are respectively provided on the front and back of the shell 1, a sorting opening is provided at the bottom of the shell 1, and a plurality of oblique support contact pins 2 penetrating into the interior are respectively provided on both sides of the shell 1. A top support contact pin 3 penetrating into the interior is fixedly connected to the top of the shell 1, and a collection box seat 5 is docked at the sorting opening at the bottom of the shell 1. 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 the plurality of oblique support contact pins 2 on both sides of the shell 1. Two detection mechanisms 6 are provided and are respectively 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 pin 3 and the oblique support contact pins 2 on both sides;

[0035] Several top support contact pins 3 on the top of the housing 1 and several oblique support contact pins 2 on both sides of the housing 1 cooperate to locate the real axis;

[0036] 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;

[0037] 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.

[0038] When in use, the real shaft to be inspected can be input from the feed port of the shell 1 by a manipulator or a transmission drive, and the real shaft entering the shell 1 is supported by a plurality of top support contact feet 3 and a plurality of oblique support contact feet 2 on both sides. The operation of the plurality of top support contact 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 contact 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 detection blind spots. After completion, the qualified real shaft is displaced along the axial direction by the top support contact 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 by a manipulator or a conveyor belt. The real shaft that fails to quench is driven by the two moving drive mechanisms 4 to drive the plurality of oblique support contact 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 and falls under the action of gravity to be collected by the collection box seat 5 to achieve the sorting effect.

[0039] 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 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.

[0040] During 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.

[0041] Reference Figure 4 The collection box seat 5 includes a box seat body 51, the top of the box seat body 51 is set as a feeding opening, and a number of built-in wheels 52 are movably sleeved inside the box seat body 51. One end of the several built-in wheels 52 passes through one side of the box seat body 51 and is connected to a number of pulley transmission assemblies 53 for transmission. A motor 2 54 is fixedly installed on the other side of the box seat body 51, and 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. A discharge opening is opened on the back of the box seat body 51.

[0042] Unqualified solid shafts enter through the feed opening at the top of the box seat body 51 and are supported by a number of built-in wheels 52. The built-in wheels 52 are driven to rotate by the power output of 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 the effect of collecting and conveying.

[0043] Reference Figure 5 The oblique support contact foot 2 includes a cylindrical shell 21, one end of the cylindrical shell 21 is fixedly connected to a support cylinder 22, and one end of the support cylinder 22 is installed with a ball contact assembly 23. A push-pull assembly 24 and a rotary drive assembly 25 are arranged inside the cylindrical 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.

[0044] 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 by the operation of the rotary drive assembly 25. Under the action of friction, the balls of the ball contact assembly 23 can be driven to rotate, and the friction between the balls 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 balls 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.

[0045] Reference Figure 6The push-pull assembly 24 includes an electric cylinder 241, which is fixedly installed inside the cylinder shell 21. The output end of the electric cylinder 241 passes through the outside of the cylinder shell 21 and is connected to a connector 242. A strip groove is provided on the side wall of the support cylinder 22. The connector 242 passes through the strip groove and is connected to a U-shaped frame 243. One side of the U-shaped frame 243 is fixedly connected to the caster assembly 26. The output end of the rotary drive assembly 25 passes through the U-shaped frame 243 and is docked with the caster assembly 26.

[0046] The output of the electric cylinder 241 can drive the U-shaped frame 243 to move under the connection effect of the connecting piece 242. Through the connection relationship between the U-shaped frame 243 and the caster assembly 26, the push-pull assembly 24 can transport and drive the caster assembly 26 to move.

[0047] Reference Figure 6 A positioning rail box 244 is provided at the bottom of the U-shaped frame 243, and the positioning rail box 244 is fixedly connected to the inner wall of the support tube 22. A T-shaped slider is slidably sleeved in the positioning rail box 244, and the T-shaped slider is fixedly connected to the bottom of the U-shaped frame 243.

[0048] The positioning rail box 244 and the T-shaped slider are provided to improve the stability of the U-shaped frame 243 during movement.

[0049] Reference Figure 7 The caster assembly 26 includes a wheel frame 261, and the inner wall of the wheel frame 261 is rotatably sleeved with a caster body 262. One end of the caster body 262 passes through the wheel frame 261 and is connected to a passive pulley 263. The wheel frame 261 is rotatably sleeved with a driving pulley 264 on one side toward the output end of the rotary drive assembly 25. A guide pulley 266 is fixedly connected to one side of the wheel frame 261. The passive pulley 263 is connected to the driving pulley 264 through a transmission belt 265. The transmission belt 265 is passed around the guide pulley 266, and the output end of the rotary drive assembly 25 is connected to the driving pulley 264.

[0050] Since the rotary drive assembly 25 serves as the rotary power mechanism of the caster assembly 26, its position setting is different from that of the traditional caster power mechanism. The rotary force is transmitted by setting a passive pulley 263, an active pulley 264, and a transmission belt 265, so as to achieve the effect of the rotary drive assembly 25 controlling the operation of the caster assembly 26, and the friction loss between the transmission belt 265 and the wheel frame 261 is avoided by setting a guide pulley 266.

[0051] Reference Figure 8 The rotary drive assembly 25 includes a motor 3 251, which is fixedly installed inside the cylinder shell 21. The output shaft of the motor 3 251 passes through the inside of the support cylinder 22 and is connected to a telescopic rod 252. The telescopic rod 252 passes through the U-shaped frame 243 and is connected to the caster assembly 26.

[0052] The telescopic rod 252 is controlled to rotate by 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, the telescopic rod 252 can be set to avoid the rotation drive assembly 25 interfering with the displacement of the caster assembly 26.

[0053] Reference Figure 8 The telescopic rod 252 includes an outer tube 253 , and an inner sliding column 254 is slidably sleeved in the inner cavity of the outer tube 253 . The inner sliding column 254 is a polygonal column, and the shape of the inner cavity of the outer tube 253 matches that of the inner sliding column 254 .

[0054] This structural arrangement prevents the telescopic rod 252 from rotating and being unable to transmit torque.

[0055] Reference Figure 9 The ball contact assembly 23 includes an end block 231, and a ball body 232 is rotatably sleeved in the inner cavity of the end block 231. The ball 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. The inner wall of the support cylinder 22 is fixedly connected with a reverse thrust frame 221. One end of the end block 231 is transmission-connected to the reverse thrust frame 221 through a spring 234. A plurality of positioning grooves penetrating into the inner cavity are provided on the periphery of the support cylinder 22, and a plurality of anti-slip blocks 233 are provided on the periphery of the end block 231. The plurality of anti-slip blocks 233 are respectively slidably sleeved in the plurality of positioning grooves.

[0056] Since some positions on the real shaft have diameter differences, the structural setting of the ball contact assembly 23 enables it to have an automatic position adjustment effect. When the ball contact assembly 23 reaches the larger diameter of the real shaft, the end block 231 of the ball contact assembly 23 is retracted into the inside of the support tube 22 due to the extrusion force. When the ball contact assembly 23 reaches the smaller diameter position of the real shaft, the elastic force of the spring 234 causes the end block 231 to extend outward from the inside of the support tube 22, ensuring that the ball contact assembly 23 is in contact with the real shaft.
