Description

Technical Field

[0001] This invention relates to the field of cylindrical pin end detection technology, and more particularly to an end detection device that facilitates the transport of cylindrical pins. Background Technology

[0002] In the vast system of modern industry, the cylindrical pin, though a small component, plays an indispensable role. From the precision and complexity of mechanical manufacturing to the high-performance automotive industry, and to the aerospace field with its extremely high requirements for safety and reliability, the cylindrical pin is ubiquitous. In the field of mechanical manufacturing, cylindrical pins are often used for the positioning and connection of parts, ensuring the accuracy of the relative positions of each component and laying the foundation for the stable operation of machinery.

[0003] The edge of a cylindrical pin is a stress concentration point and a guide contact point during assembly. It is the part most prone to defects during processing and use. If there are chipping, dents, or large cracks on the upper and lower edges of the chamfer, they will scrape hard against the edge of the pin hole during assembly, causing scratches and wear on the inner wall of the pin hole, and even deformation of the pin hole. Moreover, the guide slope of the chamfer will become discontinuous, losing its guiding alignment function, making it difficult for the cylindrical pin to be inserted into the pin hole, and even requiring forced hammering, which may cause deformation of the pin or mating parts. Usually, these materials are inspected manually, which is inefficient over time. Therefore, an end inspection device for convenient cylindrical pin conveying is proposed. Summary of the Invention

[0013] The beneficial effects of this invention are: This solution facilitates the movement of materials to one side by setting up an inclined frame plate. The inclined limiting plate facilitates the individual conveying of cylindrical pins. The self-weight steering sleeve ensures that the materials are vertical after falling in due to their own weight. The arc-shaped abutment block prevents the materials behind from falling. The eccentric wheel and impact rod vibrate the inclined frame plate, further facilitating the flow of materials. Because the clamping and reversing component is designed to easily clamp and extend the material, and then reverse it by 90 degrees, it can be used in conjunction with the conveyor to position and convey the reversed material. Because the material flipping mechanism allows the support plate to be flipped up and down easily, and the upper contact plate remains retracted while the lower contact plate remains extended during the flipping process, the upper and lower edges of the chamfered part of the cylindrical pin can be inspected using the test piece. The test piece can contact the area of ​​the upper and lower edges, and the pressure of the contact rod can be controlled by adjusting the setting of the pressure plate. The defect of the cylindrical pin can be visually identified by the disconnection between the contact rod and the contact plate.

[0014] This solution reduces the frequency of manual operation during the inspection of both ends of the cylindrical pin, lowers the possibility of errors during the inspection process, improves the effect of the device in conveying the cylindrical pins one by one, and enables the material to be inspected one by one. The inspection results are more accurate, and the detection effect of the device at multiple angles and positions is improved. In addition, the release of the contact rod makes the detection structure more intuitive and obvious. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Refer to Figure 1-11 An end detection device for facilitating the conveying of cylindrical pins includes an inclined plate 1, a material turning mechanism 4, and a support base 5. Controllers are provided on the inclined plate 1, the material turning mechanism 4, and the support base 5. A self-weight steering sleeve 13 is movably connected to the bottom edge of the inclined plate 1. A cylindrical pin body 6 is connected inside the inclined plate 1 and the self-weight steering sleeve 13. A clamping and reversing assembly 2 is installed on the bottom side of the cylindrical pin body 6. An eccentric wheel 14 is also installed on the bottom side of the inclined plate 1. An impact rod 16 is movably connected to the eccentric wheel 14. A conveying platform 111 is also provided on the outer side of the inclined plate 1. A conveying component 3 is movably connected to the conveying platform 111. A support plate 34 is installed on the conveying component 3. The material turning mechanism 4 is installed on one side of the conveyor table 111. The material turning mechanism 4 includes a turning block 44, a turning frame 41, a turning plate 42, a fixed guide cylinder 47 and a first contact plate 43. The turning block 44 is rotatably connected in the turning frame 41, the turning plate 42 is fixed on the outer side of the turning block 44, and the support plate 34 is connected in the turning plate 42. The support base 5 is located on the other side of the conveyor table 111. A lifting plate 51 is movably connected to the support base 5. A test piece 7 is installed on the bottom surface of the lifting plate 51. The test piece 7 includes a mounting plate 71, an outer ring frame 711, a mounting column 72, and a transmission plate 74. The outer ring frame 711 is installed on the bottom side of the mounting plate 71. An inner plate 721 is provided inside the outer ring frame 711. A guide ball 751 is movably connected between the inner plate 721 and the outer ring frame 711. A support leg 73 is provided on the bottom surface of the guide ball 751. An abutment plate 75 is installed on its top surface. A top plate 743 is installed on the transmission plate 74. The top plate 743 is connected to the abutment plate 75.

[0019] Specifically, the inclined frame plate 1 is inclined, and inclined limiting plates 11 are symmetrically installed inside the inclined frame plate 1. Material flow channels are provided between the inclined limiting plates 11. The cylindrical pin body 6 passes through the material flow channels one by one, and the self-weight of the rotating sleeve 13 is connected to the outlet of the material flow channel to catch the falling material in time. An arc-shaped abutment block 132 is installed on one side of the self-weight steering sleeve 13. The arc-shaped abutment block 132 has a certain weight. When the cylindrical pin body 6 has not moved into the self-weight steering sleeve 13, the self-weight steering sleeve 13 will rotate forward due to the weight of the arc-shaped abutment block 132. When the cylindrical pin body 6 falls into the self-weight steering sleeve 13, the weight at the rear end of the self-weight steering sleeve 13 will be greater, and the self-weight steering sleeve 13 will rotate backward. Support shafts 131 and self-weight limiting plates 133 are installed on both sides of the arc-shaped abutment block 132. A notch is opened at the center of the bottom edge of the inclined frame plate 1. The support shaft 131 is rotatably connected between the inner walls of the notch to facilitate the rotation and conveying of the cylindrical pin body 6. Inner wall frames are also fixed on the inner walls on both sides of the notch. The self-weight limiting plates 133 are connected to the inner wall frames and act on the angle limit when the self-weight steering sleeve 13 rotates forward, ensuring the self-weight steering sleeve The position of 13 corresponds to the material flow channel. An end limit piece 134 is also installed on one end of the arc-shaped contact block 132. The end limit piece 134 limits the rotation of the self-weight steering sleeve 13 when it rotates backward, ensuring the vertical state of the self-weight steering sleeve 13. A rubber pad 135 is installed on the inner wall of the outlet end of the self-weight steering sleeve 13. The cylindrical pin body 6 is connected between the rubber pads 135 to prevent the cylindrical pin body 6 from falling directly when the self-weight steering sleeve 13 is in a vertical state. A horizontal plate is also installed on the inclined frame plate 1. A pressing cylinder 12 is set on the horizontal plate. The telescopic end of the pressing cylinder 12 is movably connected to the self-weight steering sleeve 13 in a vertical state. It acts to press the cylindrical pin body 6 inside downward, so that its bottom end protrudes from the bottom side of the self-weight steering sleeve 13. If there are problems such as jamming when the self-weight steering sleeve 13 rotates by its own weight, it can be replaced by a motor-driven rotation.

[0020] Furthermore, the clamping and reversing assembly 2 includes a fixed frame 21, a first rotating frame 26, a steering linkage 24, and a drive disc 25. The fixed frame 21 is fixedly mounted on the inclined frame plate 1. A first drive roller is mounted on the upper side of the fixed frame 21 to control the rotation of the first rotating frame 26. The first rotating frame 26 is "n"-shaped, with one end mounted on the outer surface of the first drive roller to rotate synchronously with it. A first telescopic cylinder 22 is mounted on the first rotating frame 26. After being clamped by the electrically controlled clamping component 23, the cylinder 22 can extend and retract to facilitate the removal of the cylindrical pin body 6 from the self-weight steering sleeve 13. The telescopic end of the first telescopic cylinder 22 is equipped with an electrically controlled clamping component 23, which is an electrically driven gripper connected to the bottom end of the cylindrical pin body 6. A bevel gear set 27 is installed inside the first rotating frame 26. The bevel gear set 27 includes a first bevel tooth and a second bevel tooth. The bevel gear is installed on the base of the first telescopic cylinder 22, which is rotatably connected to the first rotating frame 26. A fixed sleeve is installed on the fixed frame 21. The second bevel gear is installed on one side of the fixed sleeve. One end of the first rotating frame 26 is rotatably connected to the outside of the fixed sleeve to achieve the effect of support and limit. The first and second bevel gears mesh with each other to rotate the angle of the electrically controlled clamping component 23, which can reduce the possibility of the cylindrical pin body 6 slipping out from the electrically controlled clamping component 23 when the first rotating frame 26 is flipped. A second drive roller is installed on the bottom side of the fixed frame 21. A synchronous toothed wheel 28 is installed on the second drive roller. A drive disc 25 is installed on one end of the second drive roller. The drive disc 25 is located on the outside of the fixed frame 21. The steering linkage 24 is connected between the drive disc 25 and the first drive roller to facilitate the cyclic angle swing of the first rotating frame 26, so as to continuously remove the cylindrical pin body 6. An active shaft is also mounted inside the inclined frame plate 1. An eccentric wheel 14 is installed on the outer surface of the active shaft. A main shaft motor is installed at one end of the active shaft. A suspension frame is also installed between the inner walls of the inclined frame plate 1. The impact rod 16 is spring-connected in the suspension frame for quick reset after impact. The bottom end of the impact rod 16 is connected to the eccentric wheel 14. A buffer block 15 is connected to the top end of the impact rod 16. When the vibration of the inclined frame plate 1 is not required, the position of the buffer block 15 can be adjusted to avoid contact with the impact rod 16. The buffer block 15 is installed on the inclined frame plate 1. A synchronous toothed wheel 28 is also installed on the outer surface of the active shaft. A synchronous drive belt is connected between the two synchronous toothed wheels 28 to facilitate control of the rotation of the drive disc 25.

[0021] In this embodiment, a linear drive component is installed inside the conveyor table 111. This linear drive component is a screw motor or electric push rod, etc. The conveyor component 3 is movably connected inside the conveyor table 111. The conveyor component 3 includes a conveyor seat, a second rotating frame 31, a clamping frame 32, and a support plate 34. The conveyor seat is movably connected inside the conveyor table 111 to facilitate moving the support plate 34 and the cylindrical pin body 6 to the designated test position. A flipping shaft is installed on one end of the second rotating frame 31. The two ends of the flipping shaft are mounted on the conveyor seat to achieve the effect of rotational support. External gears 36 are installed on both ends of the flipping shaft. A rack is installed on the top surface of the conveyor table 111. The rack and the external gears 36 mesh with each other to perform a 90-degree flip when the second rotating frame 31 reaches the designated position. A first slide rail is installed on the second rotating frame 31. Two clamping frames 32 are symmetrically installed. The two clamping frames 32 are connected to the first slide rail to facilitate the stable movement of the clamping frames 32. A clamping motor 37 is provided on the bottom side of 1. The output end of the clamping motor 37 extends to the space between the first slide rails. A clamping connecting rod 38 is installed on the output end of the clamping motor 37. The two ends of the clamping connecting rod 38 are connected to the clamping frames 32 on both sides. Each clamping frame 32 is provided with a clamping plate 33. The clamping plate 33 has the same thickness as the support plate 34 to facilitate smooth entry into the flipping plate 42. The clamping plate 33 is connected to both sides of the support plate 34. The inner walls of the clamping plate 33 are all equipped with clamping plates 33. The support plate 34 is equipped with hemispherical retaining beads, which are connected to the hemispherical retaining grooves of the support plate 34 to stabilize the clamping plate 33 and prevent the clamping plate 33 from slipping during the rotation of the second rotating frame 31. The support plate 34 has a clamping groove at its center, and multiple rubber clamping blocks 35 are spring-loaded in the clamping groove. The cylindrical pin body 6 is connected between the rubber clamping blocks 35 to achieve the effect of positioning and clamping, which can reduce the cylindrical pin body 6 from falling or moving again after clamping.

[0022] Working principle: When it is necessary to perform quality inspection on the cylindrical pin body 6, a portion of the material is taken out from the cylindrical pin body 6 that has just been produced or has been used for a period of time and placed into the inclined frame plate 1. The cylindrical pin body 6 will be concentrated along the slope to the inclined limiting plate 11, and then move one by one from the material flow channel into the gravity steering sleeve 13. When the cylindrical pin body 6 falls into the gravity steering sleeve 13, its center of gravity will shift backward, and the gravity steering sleeve 13 and the arc-shaped contact block 132 will flip outward until the end limiting piece 134 abuts against the inclined frame plate 1. At this time, the gravity steering sleeve 13 is in a vertical state, and the cylindrical pin body 6 will contact the rubber pad 135 and will not fall out directly. Then, the pressing cylinder 12 is controlled to extend downward and push the bottom end of the cylindrical pin body 6 to the outside of the gravity steering sleeve 13. Then, the main spindle motor is controlled to rotate, which drives the synchronous gear 28 to rotate, and the drive disc 25 to rotate. Under the connection of the steering linkage 24, the first drive roller rotates, and the first rotating frame 26 moves to the vertical position and stops. Then, the first telescopic cylinder 22 is controlled to extend upward to a suitable height, and the electrically controlled clamping component 23 is controlled to clamp the bottom end of the cylindrical pin body 6. After clamping, the first telescopic cylinder 22 retracts until the cylindrical pin body 6 is completely removed from the self-weight steering sleeve 13. Then, the main spindle motor is controlled to rotate again, and the first rotating frame 26 rotates downward. During the rotation, the bevel gear group 27 meshes with each other, and the first telescopic cylinder 22 and the electrically controlled clamping component 23 begin to rotate. When the first rotating frame 26 rotates to the horizontal position, the electrically controlled clamping component 23 is in the vertical position. At this time, the electrically controlled clamping component 23 clamps the upper and lower sides of the cylindrical pin body 6. At this time, the linear drive is controlled to move. When it moves to the designated position, the external gear 36 will mesh with the rack. At this time, the second rotating frame 31 will rotate 90 degrees to a vertical position. Then, the first telescopic cylinder 22 is controlled to extend the cylindrical pin body 6 forward until it is inserted between the rubber clamping blocks 35. The rubber clamping blocks 35 will stably clamp and support the cylindrical pin body 6. Then, the linear drive is operated in reverse, and the external gear 36 and the gear are reconnected. The second rotating frame 31 will rotate back to its original position. At this time, the support plate 34 is in a horizontal state.

The two ends of the cylindrical pin body 6 are respectively connected to the first abutment plate 43 and the second abutment plate 46. The support on plate 46 acts on the cylindrical pin body 6 during testing to prevent it from falling when pressed down. Movable frames 45 are installed on both the first contact plate 43 and the second contact plate 46. The two movable frames 45 are alternately telescopically connected in the steering block 44. A fixed guide cylinder 47 is installed on the front side of the rear frame plate.

Circular guide grooves are provided on both the outer ring frame 711 and the inner plate 721, and the ball movement is connected within the circular guide groove to prevent the guide ball 751 from rotating within the circular groove.

[0026] The transmission plate 74 is connected to the outside of the mounting column 72. Multiple transmission rods 742 are fixed at the center of the transmission plate 74. A rotating gear ring 741 is installed on the top of the transmission rod 742. The rotating gear ring 741 is rotatably connected to the mounting plate 71. A drive gear 531 is meshed on one side of the rotating gear ring 741. A top surface motor 53 is installed on the lifting plate 51. The output end of the top surface motor 53 is connected to the drive gear 531. The transmission plate 74 is rotatably connected to the outside of the mounting column 72 and can detect one revolution of the cylindrical pin body 6. Both ends of the transmission plate 74 are equipped with top brackets 743. The outer surface of the top of the top of the top bracket 743 is provided with external threads.

A miniature telescopic rod is installed on the lifting plate 51 to abut the position of the support leg 73 for convenient quick return after the contact rod 745 is disengaged.

[0027] Working principle: The control conveyor 3 moves backward until the clamping plate 33 moves to both sides of the adapter groove. At this time, the control electromagnetic block is energized to fix the adsorption block. At this time, the support plate 34 is firmly fixed in the flip plate 42. Then, the control clamping motor 37 rotates, the clamping connecting rod 38 rotates, and the clamping frames 32 and clamping plates 33 on both sides move outward. Then, the lifting cylinder 52 is controlled to retract downwards, and the lifting plate 51 moves downwards until the test piece 732 contacts the top edge of the cylindrical pin body 6. At this time, the bottom end of the cylindrical pin body 6 is supported on the second contact plate 46. The spring lifting rod 731 will continuously push the test piece 732 upwards, and the bottom edge of the test piece 732 will continuously press against the top edge of the cylindrical pin body 6. Then, the top surface motor 53 is controlled to rotate, and the drive gear 531 will drive the rotating gear ring 741 to rotate. Under the connection of the transmission rod 742, the transmission plate 74 will rotate. At this time, the contact rod 745 is connected in the contact plate 75, and the test piece 732 will perform rotation detection on the top edge of the cylindrical pin body 6. When there is a large gap on the top edge of the cylindrical pin body 6, the test piece 732 will fall into the gap. At this time, the test piece 732 cannot be pressed against the top edge of the cylindrical pin body 6. As the upper edge moves, the support leg 73 encounters resistance, while the transmission plate 74 continues to rotate. When the resistance is too great, the contact rod 745 will press the inner wall spring 746 upward, and the bottom end of the contact rod 745 will disengage from the abutment plate 75. At this time, it can be visually identified that there is a notch on the upper edge of the top of the cylindrical pin body 6. Before testing, the position of the adjusting pressure plate 744 can be rotated. When the height of the adjusting pressure plate 744 is higher, the compression and rebound force of the inner wall spring 746 is smaller. At this time, it is easier for the contact rod 745 to disengage from the abutment plate 75, and smaller and shallower notches can be detected. When the height of the adjusting pressure plate 744 is lower, the compression and rebound force of the inner wall spring 746 is greater, and it is not easy for the contact rod 745 to disengage from the abutment plate 75, and larger and deeper notches can be detected. After the upper and lower edges of one end are tested, the plate is reset and the lifting plate 51 is moved upward. Then, the alternating rotary motor is controlled to rotate, and the steering block 44 will rotate 180 degrees. During the rotation, the movable frame 45 will move along the front and rear alternating grooves. The first contact plate 43 will extend outward, and the second contact plate 46 will retract backward. At this time, the rotation of the cylindrical pin body 6 is completed. The above operation is repeated to test the other end of the cylindrical pin body 6. After the test is completed, the cylindrical pin body 6 is taken out and the next cylindrical pin body 6 is tested. After the test is completed, the test results are calculated to obtain the pass rate of the batch of samples.
