Description

Technical Field

[0001] The present invention relates to the technical field of fastener detection, and particularly to a fastener installation and rotation detection device. Background Art

[0002] Fasteners are tools for fixedly connecting two non-connected objects. Common fasteners are bolt fasteners. After the bolt fasteners are produced and formed, it is necessary to detect the rotation performance generated during their installation (i.e., the maximum torque that can be withstood by rotation). Only bolt fasteners that can withstand the calibrated torque without breaking can be used.

[0003] In the existing fastener installation and rotation detection device, in the device for detecting bolt fasteners, the bolt fastener to be detected is fixed by a clamping device, and then one end of a torque measuring rod is sleeved on the upper end of the bolt and rotated. The read value returned is relied on to judge whether the bolt fastener is qualified. However, when factories produce bolts, they are produced in large quantities. That is, during sampling inspection, there are also multiple batches, and some are jointly selected. This makes it necessary to detect a large number of bolt fasteners at one time. During large-scale detection, relying on manual insertion of bolt fasteners for arrangement, then fixing, and finally performing screwing detection is extremely time-consuming. Moreover, the bolts are small in size, and for one-by-one detection, it is extremely inconvenient to manually select, arrange, place, and fix them one by one, which is time-consuming and laborious, thus greatly affecting the detection efficiency and being not conducive to large-scale multi-batch detection and use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a fastener installation and rotation detection device is proposed. Summary of the Invention

[0009] Preferably, the pushing and pulling mechanism further includes a same pushing seat sleeved on the surface of the reciprocating lead screw and the guide rod. The pushing seat is slidably connected to the guide rod and is in threaded connection with the reciprocating lead screw. The upper end of the pushing seat is rotatably connected to a movable plate. The upper end of the movable plate is rotatably connected to the bottom end of the lifting plate.

[0010] Preferably, the left ends of the connecting rods are fixedly connected to the same baffle. The shape of the baffle is "L". The interval between the horizontal plate of the baffle and the rear connecting rod is the same as the diameter of the cap of the bolt fastener. A discharge groove is provided on the upper surface of the base inside the baffle. The discharge groove is an inclined surface sloping forward.

[0011] Preferably, a fixing seat is fixedly installed on the upper side and rear side of the outer surface of the base. Support rods are fixedly connected to both the left and right sides of the upper surface of the fixing seat. A screw rod is rotatably connected to the middle of the upper surface of the fixing seat.

The output shaft of the servo motor penetrates through the top cover and is fixedly connected to the upper end of the screw rod.

[0013] Preferably, the surfaces of the support rod and the screw rod are sleeved with the same adjusting block. The adjusting block is slidably connected to the support rod and is in screw connection with the screw rod. The front side of the adjusting block is fixedly connected to an extension plate.

[0017] 4. During the whole working process of the entire device of the present invention, there is no need for manual operation on the bolt fasteners.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 - 4 shown, a fastener installation rotation detection device includes a base 1. A through cavity 2 is formed on the right side of the upper surface of the base 1. A lifting plate 3 is slidably inserted into the interior of the through cavity 2. The upper surface of the lifting plate 3 is set as an inclined surface that slopes forward. A placement box 4 is fixedly installed on the upper side of the outer surface of the base 1 behind the through cavity 2. The bottom surface of the inner surface of the placement box 4 is set as an inclined surface that slopes forward, and the front end of the placement box 4 is slidably attached to the rear surface of the lifting plate 3. A fixed block 5 is fixedly installed on the upper side of the outer surface of the base 1 in front of the through cavity 2. A conveyor belt 6 is rotatably arranged on the upper inner surface of the fixed block 5. A driving motor 7 is fixedly installed on the right side of the front surface of the fixed block 5. The driving motor 7 is connected to the conveyor belt 6. Connecting rods 9 are fixedly connected to the left side of the surface of the fixed block 5 in a front-to-back distribution. A pushing and pulling mechanism 8 is arranged on the right side of the inner surface of the base 1. A controller 22 is fixedly connected to the front side of the outer surface of the base 1.

[0022] By adopting the above technical solution, the placement box 4 can directly hold the bolt fasteners used in batch sampling inspection, and utilize the inclined surface at the bottom of the placement box 4 to make the bolt fasteners roll towards the lifting plate 3; The lifting plate 3 can move up and down through the through cavity 2; When the lifting plate 3 moves down to the maximum depth and its top is flush with the front end opening of the placement box 4, the bolt fasteners will continue to roll onto the upper surface of the lifting plate 3 by using the inclined surface. Since the upper end of the lifting plate 3 is also set as an inclined surface, the bolt fasteners will continue to roll forward. At this time, the bolt fasteners are limited and blocked by the rear side of the fixed block 5. When the lifting plate 3 moves up, it will lift some bolt fasteners up. Due to the width of the lifting plate 3, only the bolt fasteners placed horizontally can be stably placed on the upper side, and the remaining longitudinally or inclined bolt fasteners will fall into the placement box 4 and roll and rearrange again; The maximum rising height of the lifting plate 3 will make the frontmost position of its inclined surface level with the fixed block 5. Under the guidance of the inclined surface at the upper end of the lifting plate 3, the horizontally placed bolt fasteners will continue to roll forward to the upper side of the fixed block 5 and enter the surface of the conveyor belt 6 with a slightly concave middle part; The driving motor 7 will drive the conveyor belt 6 to rotate to the left to transport the horizontally placed bolt fasteners, so that the bolt fasteners enter the connecting rods 9 on the left side of the fixed block 5. The bolt fasteners will automatically arrange on the connecting rods 9 and be pushed by the subsequent bolt fasteners continuously conveyed by the conveyor belt 6, and will gradually move to the left for automatic feeding.

[0023] Furthermore, the plane position of the upper surface of the conveyor belt 6 is lower than the plane position of the upper surface of the fixed block 5. The upper side of the surface of the connecting rod 9 is level with the upper surface of the conveyor belt 6, and the middle gap between the front and rear two connecting rods 9 is greater than the diameter of the threaded column body of the bolt fastener and less than the diameter of the cap body of the bolt fastener.

[0024] By adopting the above technical solution, since the upper surface position of the conveyor belt 6 is lower than that of the fixed block 5, even if the bolt fastener rolls from the rear side onto the upper surface of the conveyor belt 6, it cannot continue to roll forward, avoiding the situation where the bolt fastener falls off the fixed block 5 due to excessive rolling; The connecting rod 9 and the conveyor belt 6 on the same plane can ensure that the conveyor belt 6 can normally and stably send the bolt fasteners to the connecting rod 9 for arrangement; Due to the gap size in the middle of the front and rear connecting rods 9, the nut part of the bolt fastener cannot fall, and only the threaded column part can fall, so that all the bolt fasteners transported to the connecting rod 9 are automatically arranged vertically with the nut on top and the column part downward.

[0025] Further, the pushing and pulling mechanism 8 includes brackets 801 fixedly installed on the front and rear sides of the right inner surface of the base 1. On the opposite side of the brackets 801, a guide rod 803 and a reciprocating lead screw 802 are arranged in sequence from left to right. The guide rod 803 is fixedly connected to the bracket 801, the reciprocating lead screw 802 is rotatably connected to the bracket 801, and the front end of the reciprocating lead screw 802 penetrates through the front bracket 801 and is connected to a rotating motor 806.

[0026] By adopting the above technical solution, the rotating motor 806 provides the power for the reciprocating lead screw 802 to rotate, and the bracket 801 limits the maximum front and rear movement positions.

[0027] Further, the pushing and pulling mechanism 8 further includes a same pushing seat 804 sleeved on the surface of the reciprocating lead screw 802 and the guide rod 803. The pushing seat 804 is slidably connected to the guide rod 803 and is in threaded connection with the reciprocating lead screw 802. The upper end of the pushing seat 804 is rotatably connected to a movable plate 805, and the upper end of the movable plate 805 is rotatably connected to the bottom end of the lifting plate 3.

[0028] By adopting the above technical solution, under the limitation of the guide rod 803 on the pushing seat 804, the pushing seat 804 will not rotate together with the reciprocating lead screw 802, and will only move back and forth cyclically under the thread pushing force; When the pushing seat 804 moves backward, it will drive the lower end of the movable plate 805 to move backward, and the upper end of the movable plate 805 will pull the lifting plate 3, causing the lifting plate 3 to move downward under the limitation of the through cavity 2; When the pushing seat 804 moves forward, it will drive the lower end of the movable plate 805 to move forward, and the upper end of the movable plate 805 will push the lifting plate 3, causing the lifting plate 3 to move upward under the limitation of the through cavity 2.

[0029] Such as Figure 1 、 Figure 2 and Figure 5As shown in the figure, the left end of the connecting rod 9 is fixedly connected with the same baffle 10. The baffle 10 is in an "L" shape. The interval between the horizontal plate of the baffle 10 and the rear connecting rod 9 is the same as the diameter of the cap of the bolt fastener. A discharge groove 21 is formed on the upper surface of the base 1 inside the baffle 10. The discharge groove 21 is set as an inclined plane inclined forward.

[0030] By adopting the above technical solution, when the bolt fastener is detected, the rear side is attached to the front surface of the horizontal plate of the baffle 10. Since the distance interval between the front surface of the horizontal plate of the baffle 10 and the rear connecting rod 9 can exactly accommodate the bolt fastener completely, the lower part of the bolt fastener can be completely separated from the support of the connecting rod 9 and can fall into the discharge groove 21 for automatic discharge.

[0031] Furthermore, a fixed seat 11 is fixedly installed at the upper rear side of the outer surface of the base 1. Both left and right sides of the upper surface of the fixed seat 11 are fixedly connected with support rods 12. A screw rod 13 is rotatably connected to the middle of the upper surface of the fixed seat 11; the upper ends of the support rods 12 are fixedly connected with the same top cover 14. A servo motor 15 is fixedly installed in the middle of the upper surface of the top cover 14. The output shaft of the servo motor 15 penetrates through the top cover 14 and is fixedly connected with the upper end of the screw rod 13.

[0032] By adopting the above technical solution, the top cover 14 provides an installation platform for the servo motor 15, and the servo motor 15 can provide a rotational force for the screw rod 13.

[0033] Furthermore, the surfaces of the support rod 12 and the screw rod 13 are sleeved with the same adjusting block 16. The adjusting block 16 is slidably connected with the support rod 12 and is screwed with the screw rod 13. The front side of the adjusting block 16 is fixedly connected with an extension plate 17. A screwing member 18 is rotatably connected through the front side of the surface of the extension plate 17. A same set of feeding mechanisms 19 are arranged on the lower surface of the extension plate 17 and inside the baffle 10.

[0034] By adopting the above technical solution, under the limitation of the support rod 12 on the adjusting block 16, the adjusting block 16 cannot rotate along with the screw rod 13 and can only move up and down under the screw pushing force. When the adjusting block 16 moves down, it will drive the extension plate 17 to move down, so that the screwing member 18 covers and buckles on the nut end surface of the bolt fastener. At this time, when an artificial hand-held torque measuring rod covers and buckles on the upper end of the screwing member 18 and rotates, the screwing member 18 can be rotated, and the screwing force is transmitted to the bolt fastener at the lower end. The maximum screwing force that the bolt fastener can withstand during installation can be detected by relying on the reading returned by the torque measuring rod.

[0035] Further, the feeding mechanism 19 includes a movable rod 1901 rotatably connected to the lower surface of the extension plate 17. The lower end of the movable rod 1901 is rotatably connected to an extension rod 1902. The front end of the extension rod 1902 slidably penetrates through the baffle 10. Inside the baffle 10, a recessed plate 1903 is fixedly connected. The rear end of the recessed plate 1903 is provided with an arc-shaped groove. A rubber pad 1904 is fixedly connected to the surface of the groove of the recessed plate 1903.

[0036] By adopting the above technical solution, when the extension plate 17 moves downward, the extension plate 17 will gradually push the movable rod 1901 downward. However, due to the limitation of the penetrating part of the baffle 10, the extension rod 1902 itself cannot move downward. To match the reduced distance difference when the upper end of the movable rod 1901 moves downward, the lower end of the movable rod 1901 will pull the extension rod 1902 backward, driving the recessed plate 1903 to move backward. When the recessed plate 1903 moves backward, it will push the bolt fastener through the gap 20 and move backward out of the connecting rod 9. At the moment when the support of the connecting rod 9 is lost, the rear side of the nut end of the bolt fastener will fit against the front side of the baffle 10 and the pushed recessed plate 1903 to clamp. As the extension plate 17 continues to move downward, the clamping force of the recessed plate 1903 and the rear cross plate of the baffle 10 on the bolt fastener will be greater; When the clamping is stable, it can ensure that the nut end of the bolt fastener is vertically aligned with the screwing member 18 up and down; When the extension plate 17 moves upward, it will pull the movable rod 1901 upward, and then push the recessed plate 1903 forward to reset through the extension rod 1902, releasing the clamping output force on the front side of the bolt fastener. At this time, since there is no support at the lower end of the bolt fastener, it will fall downward; When the recessed plate 1903 pushes the fastener, the rubber pad 1904 will contact the fastener first, which can not only increase the clamping friction but also avoid the situation of extrusion friction and scratching of the fastener.

[0037] Further, the recessed plate 1903 is located above the connecting rod 9, and a gap 20 is provided at the left end of the rear connecting rod 9. And the position of the gap 20 corresponds to the center position of the recessed plate 1903. Under normal conditions, the recessed plate 1903 is entirely located in front of the front connecting rod 9, and the thickness of the recessed plate 1903 and the upper edge of the baffle 10 are both lower than the height of the nut of the bolt fastener.

[0038] By adopting the above technical solution, when the recessed plate 1903 pulls the leftmost bolt fastener, the fastener can move out of the connecting rod 9 through the gap 20, so as to clamp the bolt fastener by the cooperation of the recessed plate 1903 and the baffle 10; In the reset state of the recessed plate 1903, it is located in front of the front connecting rod 9, so as to ensure that when the bolt fastener moves to the leftmost side, it can be directly behind the recessed part of the recessed plate 1903. The nut is higher than the upper ends of the sunken plate 1903 and the baffle 10. That is, after the bolt fastener is clamped, the upper nut can be normally and stably combined and nested with the bottom end of the rotating part 18, avoiding obstruction by the baffle 10 or the sunken plate 1903.

[0039] Working principle: When using the fastener installation and rotation detection device, first, when a large number of fastener bolts are sampled, the staff only need to put all the bolt fasteners into the placement box 4. Under the influence of the inclined plane at the bottom of the placement box 4, the bolt fasteners will roll forward and fit against the rear side of the lifting plate 3. At this time, the rotary motor 806 drives the reciprocating lead screw 802 to rotate. Under the limitation of the guide rod 803 on the propulsion seat 804, the propulsion seat 804 will not rotate together with the reciprocating lead screw 802, but will only move back and forth cyclically under the thread pushing force. Thus, the movable plate 805 is used to push and pull the lifting plate 3. The lifting plate 3 will move up and down under the push and pull force limited by the through cavity 2. When the lifting plate 3 moves down to the maximum depth and its top is flush with the front end opening of the placement box 4, the bolt fasteners will continue to roll onto the lifting plate 3 by using the inclined plane. At this time, the bolt fasteners are limited and blocked by the rear side of the fixed block 5. Then, the movable plate 805 will move forward and lift, so that the lifting plate 3 carries the bolt fasteners and fits against the rear side of the fixed block 5 and moves up. When moving up, due to the width of the lifting plate 3, only the horizontally placed bolt fasteners can be stably placed on the upper side, and the rest of the longitudinally or obliquely placed bolt fasteners will fall into the placement box 4 and roll and arrange again. The maximum rising height of the lifting plate 3 will make the frontmost position of its inclined plane level with the fixed block 5. At this time, under the guidance of the upper inclined plane of the lifting plate 3, the horizontally placed bolt fasteners will continue to roll forward to the upper side of the fixed block 5 and enter the surface of the conveyor belt 6 with a slightly concave middle part. The driving motor 7 will drive the conveyor belt 6 to rotate to the left to transport the horizontally placed bolt fasteners, so that the bolt fasteners enter the connecting rod 9 on the left side of the fixed block 5. Due to the gap size in the middle of the front and rear connecting rods 9, the nut part of the bolt fastener cannot fall, and only the threaded cylinder part can fall. Thus, all the bolt fasteners transported to the connecting rod 9 will automatically be vertically arranged with the nut on the upper side and the cylinder part downward. The bolt fasteners on the left side will be pushed by the continuously transported bolt fasteners behind and continue to move to the left. When the leftmost bolt fastener moves to the left end position of the connecting rod 9 and fits against the extension rod 1902, at this time, the rear side of the cylinder of the bolt fastener corresponds to the intermittent position 20. Then, the controller 10 can first pause the work of the conveyor belt 6 and the lifting plate 3. Then, the servo motor 15 can be started to drive the screw 13 to rotate. Under the limitation of the support rod 12 on the adjustment block 16, the adjustment block 16 cannot rotate together with the screw 13, but will only move up and down under the thread pushing force. When the adjustment block 16 moves down, it will drive the extension plate 17 to move down. When the extension plate 17 moves down, the extension plate 17 will gradually push down the movable rod 1901. And the extension rod 1902 itself is restricted by the penetrated part of the baffle 10 and cannot move down. In order to match the reduced distance difference when the upper end of the movable rod 1901 moves down, the lower end of the movable rod 1901 will pull the movable extension rod 1902 to move backward, which will drive the concave plate 1903 to move backward. When the concave plate 1903 moves backward, it will push the bolt fastener through the intermittent position 20 and move it out of the connecting rod 9.At the moment when the support of the connecting rod 9 is lost, the rear side of the nut end of the bolt fastener will fit against the front side of the baffle 10 and fit against the depressed plate 1903 being pushed, so as to carry out clamping. As the extension plate 17 continuously moves downward, the clamping force of the depressed plate 1903 and the transverse plate on the rear side of the baffle 10 on the bolt fastener will be greater. And when the clamping is stable, it can ensure that the nut end of the bolt fastener is vertically aligned with the rotating member 18 up and down. At this time, the rotating member 18 will move downward following the extension plate 17. When the bolt fastener is fixed, the bottom end of the rotating member 18 will just cover and buckle on the surface of the nut end of the bolt fastener. At this time, when a person holds the torque measuring rod and covers and buckles it on the upper end of the rotating member 18 and rotates it, the rotating member 18 can be rotated, and the rotation force can be transmitted to the bolt fastener at the lower end. Relying on the reading returned by the torque measuring rod, the maximum rotation force that the bolt fastener can withstand during installation can be detected. After the detection is completed, the servo motor 15 rotates in the reverse direction, thereby driving the screw rod 13 to reverse, so that the adjusting block 16 drives the extension plate 17 to move upward. At this time, the rotating member 18 will disengage from the nut part of the bolt fastener. Moreover, when the extension plate 17 moves upward, it will pull the movable rod 1901 upward, and then push the depressed plate 1903 forward to reset through the extension rod 1902, releasing the clamping output force on the front side of the bolt fastener. At this time, since there is no support at the lower end of the bolt fastener, it will fall downward and enter the discharge chute 21. Using the inclined plane of the discharge chute 21, the entire detection device can be automatically discharged without manual extraction; When performing the detection of the next bolt fastener, since a plurality of bolt fasteners have been neatly arranged on the connecting rod 9 during the first conveying of the fasteners, it is not necessary to start the conveyor belt 6 to push for the detection of the second bolt fastener. It only needs to manually push the bolt fastener to slide along the connecting rod 9 to the left to perform rapid feeding, and there is no need to manually arrange the fasteners. Moreover, direct manual pushing is faster than pushing the fasteners one by one relying on the subsequent arranged bolt fasteners. This is the working principle of the fastener installation and rotation detection device.
