Description

Technical Field

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

[0002] An expansion bolt is a fastener that uses a wedge-shaped slope to cause expansion and generate frictional holding force. It is usually composed of components such as bolts and expansion tubes. 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 the equipment or component.

[0003] In order to ensure that the quality of expansion bolts meets the standards so that they can firmly fix and connect equipment or components in actual applications, industrial cameras are usually used to monitor their assembly status. However, since industrial cameras are mostly fixed and have limitations in the detection range, they cannot perform multi-directional inspections on expansion bolts. This may result in some potential defects in expansion bolts that are not easy to detect, which in turn has an adverse effect on the quality after assembly.

[0004] For example, the Chinese patent (application number: 201620569370.1) discloses an "automatic conveying system for an implosion expansion screw assembly machine". Its specification discloses that currently existing implosion 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 also requires a lot of labor costs, which increases production costs and reduces production efficiency. The above patent can prove the defects of the existing technology.

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

[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] As described in the background art, since most industrial cameras are fixed and have limitations in their detection range, they are unable to perform multi-directional inspections on expansion bolts, which may result in some potential defects in the expansion bolts that are not easily detected, thereby adversely affecting the quality after assembly.

There are two arc tooth plates 814 fixedly connected, and a number of auxiliary gears 807 are evenly distributed on the circumference above the positioning ring 816, and a connecting shaft 808 is movably connected to the auxiliary gear 807. The middle part of the outer wall of the connecting shaft 808 is movably connected to the half frame 803, and the rear end of the half frame 803 is fixedly connected to the side shaft 810, and the outer wall of the side shaft 810 is fixedly connected to the side gear 809. The lower part of the side gear 809 is meshed with the upper part of the arc tooth plate 814, and the side of the auxiliary gear 807 is meshed with the side of the side tooth plate 812. The assembled expansion bolts fall into the elastic rack 804 and the elastic auxiliary plate 813 under the drive of gravity. The expansion bolt is clamped in the middle, and then along with the rotation of the auxiliary plate 801, the elastically clamped expansion bolt passes through the first industrial camera 10, and the appearance of one side is monitored and recorded. Then the auxiliary gear 807 under the half frame 803 is meshed with the side tooth plate 812 located on one side of the circular ring plate 815. As it rotates, along with the cooperation of the connecting shaft 808, the bottom frame plate 811 is driven to rotate, and the clamped expansion bolt is rotated, so that the other side of the expansion bolt faces the inner wall of the shell 2.

[0026] In order to enable those skilled in the art to better understand the solutions 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.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] Example 1, please refer to Figure 6 An expansion screw assembly machine is disclosed, wherein the upper end of a connecting shaft 808 passes through a half frame 803 and is fixedly connected to a base plate 811 above. An elastic tooth rack 804 is fixedly connected to one side of the base plate 811, and an elastic auxiliary plate 813 is fixedly connected to the other side of the base plate 811. The elastic tooth rack 804 and the elastic auxiliary plate 813 cooperate with each other to clamp the falling expansion bolt to prevent it from escaping from the limit plate 806 during the detection process.

[0030] Further, such as Figure 6 and Figure 7 As shown, a plurality of limit grooves 805 are evenly distributed in a straight line on the surface of the elastic tooth rack 804 and the elastic auxiliary plate 813, and a limit plate 806 is movably connected between two relatively distributed limit grooves 805. The plurality of limit grooves 805 are used to accommodate expansion bolts of different sizes, and the limit plate 806 is inserted into the limit groove 805 to support it.

[0031] Further, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the side shaft 810 passes through the side gear 809 and is fixedly connected to a right-angle frame 802. Auxiliary plates 801 are fixedly connected above several right-angle frames 802. A discharge assembly 9 is provided below the auxiliary plates 801. By installing several right-angle frames 802 on the auxiliary plates 801, multiple expansion bolts can be inspected in sequence to improve their efficiency.

[0032] Embodiment 2 further optimizes the expansion screw assembly machine provided in Embodiment 1. Specifically, Figure 1 , Figure 3 , Figure 4 and Figure 7 As 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.

[0033] 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.

[0034] 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.

[0035] 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 ring plate 815, and the debris on the circular ring plate 815 is discharged through the auxiliary holes 908 to prevent it from affecting the detection process of the expansion bolts.

[0036] Further, such as Figure 3 and Figure 7As shown, a motor 13 is fixedly connected below the support shaft 909 , and a support plate 11 is fixedly connected below the motor 13 , so that the motor 13 is supported by the support plate 11 .

[0037] Further, such as Figure 3 and Figure 7 As shown, a plurality of fixing rods 12 are evenly distributed and fixedly connected to the outer wall of the support plate 11 in a circumferential manner, and the other end of the fixing rod 12 is fixedly installed on the inner wall of the shell 2. The support plate 11 used to support the motor 13 is fixed to the inner wall of the shell 2 through the fixing rod 12.

[0038] Further, such as Figure 2 and Figure 3 As shown, three industrial cameras 10 are evenly arranged in a circle on one side above the outer wall of the housing 2 and are located below the processing table 3. The industrial cameras 10 are used to detect the assembly status of the expansion bolts.

[0039] The use process of the expansion screw assembly machine provided by the present invention is as follows: Working principle: The staff introduces the bolt, nut and sleeve into the bolt feeding mechanism 4, sleeve feeding mechanism 5 and nut feeding mechanism 6 respectively, and then driven by the power, the processing table 3 above the workbench 1 rotates to perform assembly processing. After the nut is placed, it moves to the bottom of the locking mechanism 7 and twists it to make it initially locked on the bolt; Detection: After the assembly is completed, the expansion bolt falls down, and driven by gravity, falls between the elastic gear frame 804 and the elastic auxiliary plate 813 to clamp the expansion bolt, and then along with the rotation of the auxiliary plate 801, the elastically clamped expansion bolt passes through the first industrial camera 10 to monitor and record the appearance of one side, and then the auxiliary gear 807 under the half frame 803 is engaged with the side gear plate 812 located on one side of the circular plate 815, and as it rotates, along with the cooperation of the connecting shaft 808, it drives the bottom frame plate 811 to rotate, and rotates the clamped expansion bolt, so that the other side of the expansion bolt faces the inner wall of the shell 2, and as the auxiliary plate 801 rotates, it drives the position change. The expansion bolt passes over the second industrial camera 10, and the appearance of the other side is monitored. It continues to move above the circular plate 815 with the rotation of the auxiliary plate 801, and the auxiliary gear 807 located at the rear end of the half frame 803 is meshed with the arc tooth plate 814 located above the positioning ring 816. Driven by the auxiliary plate 801, the half frame 803 rotates with the side shaft 810, and drives the clamped expansion bolt to flip. At this time, it continues to follow the auxiliary plate 801 to rotate in the inner wall of the shell 2, so that the expansion bolt passes over the third industrial camera 10 after flipping, and the position of the nut on the bolt is monitored. Through three monitorings, the assembly state of the expansion bolt is detected; Vibration fine-tuning: flip the rear half frame 803, and then continue to move and contact the oblique arc plate 901 on the upper surface of the circular plate 815. Since one end of the oblique arc plate 901 is higher than the other end, the higher end first contacts the elastic gear rack 804, and vibrates, causing the remaining clamped expansion bolts to turn to a certain extent. Multiple comparisons are performed during the monitoring process of each industrial camera 10, so as to improve the accuracy of its detection data; Classification and discharging: 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 plate 815. Since one end of the inclined arc plate 901 is higher than the other end, the higher end will first contact the elastic gear rack 804, and the expansion bolt will be separated from the clamping of the elastic gear rack 804 and the elastic auxiliary plate 813, and fall on the inclined arc plate 901, and continue to move on the circular plate 815 along the auxiliary plate 801, and the expansion bolts that have completed the detection are brought to the top of the discharge window 905 on the surface of the circular plate 815. The expansion bolts that have passed the detection are discharged along the exposed discharge window 905, and the expansion bolts that have not passed the detection start 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 the other end of the discharge window 905 is exposed, and the expansion bolts assembled in this way are classified and processed according to the detection data; Cleaning by shifting: As the baffle 906 moves above the circular plate 815 driven by the inclined rod 904 to classify the material, the baffle 906 moves toward 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 in an inclined state, the baffle 906 bends and loses the drive of the inclined rod 904. In order to restore its original state, the baffle 906 moves in the opposite direction along the upper surface of the circular plate 815, driving the upper shift plate 907 to contact the arc tooth plate 814 above the positioning ring 816, thereby generating vibration, and the debris on the surface of the circular plate 815 is discharged along the auxiliary hole 908.
