Description

Technical Field

[0001] The present invention relates to the technical field of screw assembly, and more particularly to an expansion screw assembly machine. Background Art

[0002] An expansion bolt is a fastener that uses a wedge slope to cause expansion to generate frictional gripping force. It usually consists of components such as a bolt and an expansion tube. By driving it into a pre-drilled hole and tightening the nut, the expansion tube will expand and fill the hole, thereby achieving firm fixation of equipment or components.

[0003] In order to ensure that the quality of the expansion bolt meets the standards and can firmly fix and connect equipment or components in actual applications, industrial cameras are usually used to monitor its assembly status. However, due to the fact that most industrial cameras are fixedly placed and have limitations in the detection range, they cannot detect the expansion bolt from multiple directions, which may lead to some potential defects that are not easily detectable in the expansion bolt, and thus have an adverse impact on the quality after assembly.

[0004] For example: The "automatic conveying system of an internal explosion expansion screw assembly machine" disclosed in Chinese Patent (Application No.: 201620569370.1) states in its specification that currently, existing internal explosion expansion screws generally adopt a semi-automatic installation method, which not only has low production efficiency but also cannot achieve self-detection. At the same time, a large amount of detection work requires a large amount of labor costs, increasing production costs and reducing production efficiency; the above patent can prove the defects existing in the prior art.

[0005] Therefore, we make improvements and propose an expansion screw assembly machine. Summary of the Invention

Below the processing table, there is a housing, and above the inner wall of the housing, there is a detection component.

[0010] The detection component includes a circular ring plate fixedly installed below the inner wall of the housing. One side above the circular ring plate is provided with a side tooth plate. The inner circle of the upper surface of the circular ring plate is fixedly connected with a positioning ring. Two arc tooth plates are fixedly connected symmetrically and evenly above the positioning ring. A number of auxiliary gears are movably connected in a circumferential and uniform distribution above the positioning ring. A connecting shaft is movably connected above the auxiliary gears. The middle part of the outer wall of the connecting shaft is movably connected with a semi-frame. A side shaft is fixedly connected to the rear end of the semi-frame. A side gear is fixedly connected to the outer wall of the side shaft. The lower part of the side gear is meshed with the upper part of the arc tooth plate. The side surface of the auxiliary gear is meshed with the side surface of the side tooth plate.

[0011] As a preferred technical solution of the present application, the upper end of the connecting shaft penetrates through the upper part of the semi-frame and is fixedly connected with a bottom frame plate. An elastic tooth frame is fixedly connected above one side of the bottom frame plate. An elastic auxiliary plate is fixedly connected above the other side of the bottom frame plate.

[0012] As a preferred technical solution of the present application, a number of limiting grooves are arranged in a straight line and evenly on the surfaces of the elastic tooth frame and the elastic auxiliary plate. A limiting plate is movably connected between two relatively distributed limiting grooves.

[0013] As a preferred technical solution of the present application, the side shaft penetrates through the side gear and is fixedly connected with a right-angle frame. An auxiliary plate is fixedly connected above a number of the right-angle frames. A discharging component is arranged below the auxiliary plate.

[0014] As a preferred technical solution of the present application, the discharging component includes a positive ratchet wheel arranged below the auxiliary plate. A support shaft is arranged below the positive ratchet wheel. A reverse ratchet wheel is arranged in the middle of the support shaft. An inclined rod is arranged on the outer wall of the reverse ratchet wheel. A discharging window is arranged on one side of the surface of the circular ring plate. The other end of the inclined rod penetrates through the discharging window and is fixedly connected with a baffle. An inclined arc plate is fixedly connected to the upper surface of the circular ring plate near the discharging window.

[0015] As a preferred technical solution of the present application, a number of dial plates are fixedly connected evenly on the upper surface of the baffle near the positioning ring. The dial plates are movably connected with the arc tooth plates.

[0016] As a preferred technical solution of the present application, a number of auxiliary holes are arranged evenly on the upper surface of the circular ring plate.

[0017] As a preferred technical solution of the present application, a motor is fixedly connected below the support shaft. A support plate is fixedly connected below the motor.

[0018] As a preferred technical solution of the present application, a number of fixing rods are fixedly connected to the outer wall of the support plate in a circumferential and uniform distribution. The other ends of the fixing rods are fixedly installed on the inner wall of the housing.

[0019] As a preferred technical solution of the present application, three industrial cameras are evenly arranged in a circle on one side above the outer wall of the shell and are located below the processing table.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the scheme of this application:

[0022] 1. In order to solve the problem that the existing technology is unable to perform multi-directional detection of expansion bolts due to the limitation of detection range in that most industrial cameras are fixed, which may result in some potential defects of the expansion bolts that are not easy to detect, thereby adversely affecting the quality after assembly, the present application uses the meshing relationship between the two sets of tooth plates and the gears, and under the drive of the auxiliary plate, performs steering and flipping operations, and changes the position of the expansion bolts to perform multi-directional detection, so that the expansion bolts can be detected in multiple directions to ensure the quality of the expansion bolt assembly;

[0023] 2. The position of the baffle above the discharge window is controlled by the forward and reverse rotation of the motor, thereby changing the discharge position, so that the expansion bolts can be classified and discharged according to the results of the expansion bolt detection, thereby improving the efficiency of expansion bolt assembly;

[0024] 3. During the feeding process, the elastic tooth rack and the elastic auxiliary plate cooperate with each other to clamp the falling expansion bolts. During the detection process, the elastic tooth rack will hit one end of the inclined arc plate after flipping, causing vibration, driving the remaining clamped expansion bolts to undergo a certain steering displacement, thereby changing the angle of the industrial camera's multiple monitoring processes, so that it can flexibly switch between the clamping structure and the vibration adjustment mechanism, thereby improving the efficiency of its expansion bolt detection;

[0025] 4. During the discharging process, the reverse rotation of the motor drives the inclined rod to move, and the baffle at the other end of the inclined rod moves on the surface of the circular ring plate to control the covering state of the discharging window and the baffle, so as to realize classified discharging. During the cleaning process, the baffle is driven to move above the inclined arc plate, and after it is powered, during the deformation recovery process, it drives the paddle above it to paddle the arc tooth plate to generate vibration, so as to guide the debris in the circular ring plate out of the auxiliary hole, so that the discharging control structure and the vibration auxiliary structure can be flexibly switched, thereby improving the efficiency of quality inspection of expansion bolts.

[0038] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying 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 in 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.

[0039] As described in the background art, since industrial cameras are mostly fixedly placed, there are limitations in the detection range and they cannot perform multi-directional detection on expansion bolts. This may lead to some potential defects that are not easily detectable in expansion bolts, which in turn have an adverse impact on the quality after assembly.

[0040] To solve this technical problem, the present invention provides an expansion screw assembly machine, which is applied to the technical field of screw assembly.

[0041] Specifically, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, The expansion bolt assembling machine specifically includes a workbench 1. In the middle of the upper surface of the workbench 1, there is a processing table 3. On one side of the processing table 3, there is a bolt feeding mechanism 4. At the rear end of the processing table 3, there is a sleeve feeding mechanism 5. On the other side of the processing table 3, there is a nut feeding mechanism 6. At the front end of the processing table 3, there is a locking mechanism 7. Below the processing table 3, there is a housing 2. Above the inner wall of the housing 2, there is a detection component 8. The detection component 8 includes an annular plate 815 fixedly installed below the inner wall of the housing 2. On one side above the annular plate 815, there is a side tooth plate 812. The inner circle of the upper surface of the annular plate 815 is fixedly connected with a positioning ring 816. Above the positioning ring 816, two arc tooth plates 814 are fixedly connected symmetrically and evenly. Above the positioning ring 816, a number of auxiliary gears 807 are movably connected in a circumferential and uniform distribution. Above the auxiliary gears 807, a connecting shaft 808 is movably connected. In the middle of the outer wall of the connecting shaft 808, a semi-frame 803 is movably connected. At the rear end of the semi-frame 803, a side shaft 810 is fixedly connected. On the outer wall of the side shaft 810, a side gear 809 is fixedly connected. Below the side gear 809, it is meshed and connected with the upper part of the arc tooth plate 814. The side of the auxiliary gear 807 is meshed and connected with the side of the side tooth plate 812. The assembled expansion bolt, driven by gravity, falls between the elastic tooth frame 804 and the elastic auxiliary plate 813 to clamp the expansion bolt. Then, following the rotation of the auxiliary plate 801, the elastically clamped expansion bolt passes by the first industrial camera 10, and the appearance of one side of it is monitored and recorded. Then, the auxiliary gear 807 located below the semi-frame 803 meshes with the side tooth plate 812 located on one side of the annular plate 815. With the rotation, following the cooperation of the connecting shaft 808, it drives the bottom frame plate 811 to rotate accordingly, and rotates the clamped expansion bolt, so that the other side of the expansion bolt faces the inner wall of the housing 2. With the rotation of the auxiliary plate 801, it drives the relocated expansion bolt to pass by the second industrial camera 10, and the appearance of the other side of it is monitored. Continuing to move above the annular plate 815 following the rotation of the auxiliary plate 801, the auxiliary gear 807 located at the rear end of the semi-frame 803 meshes with the arc tooth plate 814 located above the positioning ring 816. Driven by the auxiliary plate 801, the semi-frame 803 rotates around the side shaft 810, and drives the clamped expansion bolt to flip. At this time, it continues to rotate in the inner wall of the housing 2 following the auxiliary plate 801, so that the flipped expansion bolt passes by the third industrial camera 10, and the position of the nut on the bolt is monitored, so as to detect the assembly state of the expansion bolt.

[0042] The expansion bolt assembling machine provided by the present invention, through the meshing relationship between two groups of tooth plates and gears, under the drive of the auxiliary plate 801, performs turning and flipping operations, and changes the position of the expansion bolt to perform multi-directional detection, so as to be able to perform multi-faceted detection on the expansion bolt to ensure the quality of the expansion bolt assembly.

[0043] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0045] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] Example 1, please refer to Figure 6 , an expansion screw assembling machine, the upper end of the coupling shaft 808 penetrates through the upper part of the semi-frame 803 and is fixedly connected with a chassis plate 811. Above one side of the chassis plate 811, an elastic tooth rack 804 is fixedly connected. Above the other side of the chassis plate 811, an elastic auxiliary plate 813 is fixedly connected. Through the mutual cooperation of the elastic tooth rack 804 and the elastic auxiliary plate 813, the falling expansion bolts are clamped to prevent them from breaking away from above the limit plate 806 during the detection process.

[0047] Furthermore, as Figure 6 and Figure 7 shown, a plurality of limit grooves 805 are uniformly distributed in a straight line on the surfaces of the elastic tooth rack 804 and the elastic auxiliary plate 813. A limit plate 806 is movably connected between two relatively distributed limit grooves 805. Through the plurality of limit grooves 805, expansion bolts of different sizes can be adapted, and the limit plate 806 is inserted into the limit grooves 805 to support them.

[0048] Furthermore, as Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the side shaft 810 penetrates through the side gear 809 and is fixedly connected with a right-angle frame 802. Above a plurality of right-angle frames 802, an auxiliary plate 801 is fixedly connected. Below the auxiliary plate 801, there is a discharging assembly 9. By installing a plurality of right-angle frames 802 on the auxiliary plate 801, a plurality of expansion bolts can be sequentially detected, improving the efficiency.

[0049] Example 2, further optimize the expansion screw assembling machine provided in Example 1. Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the discharging assembly 9 includes a positive ratchet 902 arranged below the auxiliary plate 801, a support shaft 909 is provided below the positive ratchet 902, a counter ratchet 903 is provided in the middle of the support shaft 909, an inclined rod 904 is provided on the outer wall of the counter ratchet 903, a discharging window 905 is provided on one side of the surface of the circular ring plate 815, and a baffle 906 is fixedly connected to the discharging window 905 above the other end of the inclined rod 904, and an inclined arc plate 901 is fixedly connected to the upper surface of the circular ring plate 815 near the discharging window 905. The motor 13 rotates, and with the cooperation of the support shaft 909 and the positive ratchet 902, the auxiliary plate 801 is driven to rotate in the housing 2. As the expansion bolts are detected in sequence, the expansion bolts after flipping will contact the inclined arc plate 901 on the upper surface of the circular ring plate 815. One end of the inclined arc plate 901 is higher than the other end, and the higher end first contacts the elastic tooth rack 804, so that the expansion bolt is separated from the clamping of the elastic tooth rack 804 and the elastic auxiliary plate 813, and falls on the inclined arc plate 901, and continues to move on the circular ring plate 815 along the auxiliary plate 801, and the expansion bolt that has completed the inspection is brought to the top of the discharge window 905 on the surface of the circular ring plate 815, and the expansion bolt that has passed the inspection is discharged along the exposed discharge window 905, and the expansion bolt that has not passed the inspection starts the motor 13 to reverse, and with the assistance of the anti-ratchet 903 and the inclined rod 904, the baffle 906 is driven to rotate in the opposite direction, and moves to the top of the arc inclined plate, exposing the other end of the discharge window 905, and the expansion bolts assembled in this way are classified and processed according to the inspection data.

[0050] The position of the baffle 906 above the discharge window 905 is controlled by the forward and reverse rotation of the motor 13, thereby changing the discharge position, so that the expansion bolts can be classified and discharged according to the results of the expansion bolt detection, thereby improving the efficiency of the expansion bolt assembly.

[0051] Further, such as Figure 7 As shown, a plurality of paddle plates 907 are evenly distributed and fixedly connected to the upper surface of the baffle plate 906 near the positioning ring 816. The paddle plates 907 are movably connected to the arc tooth plate 814. The paddle plates 907 are driven by the moving baffle plate 906 and come into contact with the arc tooth plate 814, thereby generating vibration to guide the expansion bolts out.

[0052] Further, such as Figure 3 and Figure 7 As shown, a plurality of auxiliary holes 908 are evenly distributed on the upper surface of the circular plate 815, and the debris on the circular plate 815 is discharged through the auxiliary holes 908 to prevent it from affecting the detection process of the expansion bolts.

[0053] Further, such as Figure 3 and Figure 7As shown in the figure, a motor 13 is fixedly connected below the support shaft 909, and a support plate 11 is fixedly connected below the motor 13. The motor 13 is supported by the support plate 11.

[0054] Furthermore, as Figure 3 shown in Figure 7 the figure, a plurality of fixing rods 12 are fixedly connected to the outer wall of the support plate 11 in a circumferential and uniform distribution. The other ends of the fixing rods 12 are fixedly installed on the inner wall of the housing 2. The support plate 11 for supporting the motor 13 is fixed to the inner wall of the housing 2 through the fixing rods 12.

[0055] Furthermore, as Figure 2 shown in Figure 3 the figure, three industrial cameras 10 are provided on one side above the outer wall of the housing 2 in a circumferential and uniform manner, and are located below the processing table 3. The industrial cameras 10 are used to detect the assembled state of the expansion bolts.

[0056] The usage process of the expansion screw assembling machine provided by the present invention is as follows:

[0057] Working principle: The staff respectively introduce bolts, nuts and sleeves into the bolt feeding mechanism 4, the sleeve feeding mechanism 5 and the nut feeding mechanism 6. Then, driven by power, the processing table 3 above the workbench 1 rotates for assembly processing. After the nuts are placed, when they move below the locking mechanism 7, they are twisted to be initially locked on the bolts.

[0058] Detection: After the assembled expansion bolts fall, driven by gravity, they fall between the elastic tooth rack 804 and the elastic auxiliary plate 813 to clamp the expansion bolts. Then, following the rotation of the auxiliary plate 801, the elastically clamped expansion bolts pass by the first industrial camera 10, and the appearance of one side of the expansion bolts is monitored and recorded. Then, the auxiliary gear 807 below the semi-frame 803 meshes with the side tooth plate 812 on one side of the ring plate 815. With the rotation, driven by the cooperation of the coupling shaft 808, the bottom frame plate 811 rotates accordingly, and the clamped expansion bolts are rotated, so that the other side of the expansion bolts faces the inner wall of the housing 2. With the rotation of the auxiliary plate 801, the position-changed expansion bolts are driven to pass by the second industrial camera 10, and the appearance of the other side of the expansion bolts is monitored. Continuing to move above the ring plate 815 with the rotation of the auxiliary plate 801, the auxiliary gear 807 at the rear end of the semi-frame 803 meshes with the arc tooth plate 814 above the positioning ring 816. Driven by the auxiliary plate 801, the semi-frame 803 rotates around the side shaft 810, and the clamped expansion bolts are flipped. At this time, continue to rotate in the inner wall of the housing 2 following the auxiliary plate 801, so that the flipped expansion bolts pass by the third industrial camera 10, and the position of the nut on the bolt is monitored. Through three times of monitoring, the assembled state of the expansion bolts is detected.

[0059] Vibration fine-tuning: After flipping the rear half-frame 803, it continues to move and contact the inclined arc plate 901 on the upper surface of the circular ring plate 815. Since one end of the inclined arc plate 901 is higher than the other end, the higher end first contacts the elastic tooth rack 804, generating vibration, causing the other clamped expansion bolts to turn to a certain extent, and making multiple comparisons during the monitoring process of each industrial camera 10 to improve the accuracy of its detection data;

[0060] Classified discharging: As the expansion bolts are sequentially detected, the flipped expansion bolts contact the inclined arc plate 901 on the upper surface of the circular ring plate 815. Since one end of the inclined arc plate 901 is higher than the other end, the higher end first contacts the elastic tooth rack 804, and the expansion bolts are disengaged from the clamping of the elastic tooth rack 804 and the elastic auxiliary plate 813, and fall onto the inclined arc plate 901, and continue to move on the circular ring plate 815 along the auxiliary plate 801. The expansion bolts that have completed the detection are brought above the discharge window 905 on the surface of the circular ring plate 815. The expansion bolts that pass the detection are exported along the exposed discharge window 905, while the expansion bolts that do not pass the detection start the motor 13 to reverse. With the assistance of the reverse ratchet 903 and the inclined rod 904, the baffle 906 is driven to rotate in the reverse direction, and the other end of the discharge window 905 is exposed. In this way, the assembled expansion bolts are classified and processed according to the detection data;

[0061] Poking and cleaning: Since the baffle 906 moves above the circular ring plate 815 driven by the inclined rod 904 to classify and discharge materials, the baffle 906 moves towards the surface of the inclined arc plate 901 with the power of the inclined rod 904. Since the upper surface of the inclined arc plate 901 is inclined, the baffle 906 is bent, and when it loses the drive of the inclined rod 904, in order to return to its original state, the baffle 906 moves in the reverse direction along the upper surface of the circular ring plate 815, driving the upper dial 907 to contact the arc tooth plate 814 above the positioning ring 816, generating vibration, and discharging the debris on the surface of the circular ring plate 815 along the auxiliary hole 908.
