Description

Technical Field

[0001] The invention relates to the field of square tube assembly and processing, in particular to an assembly machine for a plugging head for plugging a square tube. Background Art

[0002] Currently, many computer monitors and large conference room items use more flexible brackets to display at different angles. The brackets made of metal square tubes have strong supporting strength and light overall weight, which is convenient for users to move and adjust. Therefore, there are many square tube screen brackets on the market, and there are many types.

[0003] In the current production process of the bracket, it is necessary to seal the side opening of the square tube. Generally, a hydraulic device is used to squeeze the sealing head directly on both ends of the square tube. However, in the current machinery and equipment, when squeezing the square tube, a one-time straight punching method is adopted, which can easily squeeze and deform the square tube. Moreover, the square tube and the sealing head are fed by a vibrating screen, which can easily cause scratches on the metal square tube, resulting in an unsightly finished product.

[0004] The technical problem to be solved by the present application is: how to reduce the wear on the square tube to reduce the defective rate, and how to accurately and firmly assemble the plug head at the side opening of the square tube. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a square tube plugging assembly machine which has the advantages of accurate and firm assembly of the plugging head, small wear on the square tube and low defective rate.

[0006] The technical solution adopted by the present invention is: a plug assembly machine for plugging square tubes, comprising a square tube rack and a plug pushing device, an assembly center is arranged directly below the square tube rack, a tube pushing device for pushing square tubes is arranged on one side of the assembly center, the plug pushing devices are symmetrically arranged on both sides of the assembly center, the plug pushing device comprises a plug connecting arm, a side channel connected to the assembly center is arranged at the end of the plug connecting arm, a fixed plug wall and a plug sending telescopic arm for pushing the plug are respectively arranged at two opposite side ends of the side channel, a plug pushing telescopic arm is arranged on the side of the side channel away from the assembly center, a fixed tube wall that can move forward and backward is arranged on the side of the assembly center away from the square tube rack, and a plug sealing telescopic arm is arranged at a position horizontal to the outer wall of the fixed tube wall on one side of the assembly center;

[0007] In the present invention, the plugging head of the square tube is pushed into the side channel by the plug-feeding telescopic arm, and the square tube is pushed into the assembly center by the tube-pushing device at the same time. At this time, the plugging head is located at both side ends of the square tube, so that when the plug-pushing telescopic arm is extended, the plugging head can be pre-installed on both ends of the square tube, and the pre-installed square tube with the plugging head continues to move backward and is then squeezed by the plugging telescopic arm, so that the plugging head is firmly assembled on both side ends of the square tube. In the device, the installation position of the plugging head is accurate and the installation is tight and firm, thereby improving the yield after assembly, and the square tube is processed after being pushed out, which can reduce the wear on the outer wall of the square tube, thereby avoiding scratching the square tube.

[0008] In some embodiments, the square tube rack includes two rack bodies that are vertically placed in a centrally symmetrical shape, and a connecting pipe plate is provided at the bottom of the rack body.

[0009] In some embodiments, a tongue capable of extending between two frames is provided at the bottom of each frame, and a cylinder for controlling the movement of the tongue is provided at one side of the frame.

[0010] In some embodiments, the width of the retaining tongue is smaller than the inner diameter width of the square tube.

[0011] In some embodiments, the tube pushing device includes a tube pushing telescopic arm, and a pushing plate is provided at the telescopic end of the tube pushing telescopic arm.

[0012] In some embodiments, a workbench is provided at the bottom of the square tube rack and the plug pushing device, and the square tube rack is located in the center of the workbench.

[0013] In some embodiments, a linear track is provided on the workbench, and a sliding seat slidably assembled on the linear track is provided at the bottom of the plug pushing device.

[0014] In some embodiments, a fixed side plate is provided on one side of the sliding seat, and a plurality of positioning holes are provided on the linear track corresponding to the fixed side plate.

[0015] The beneficial effects of the present invention are:

[0016] (1) In the present invention, the plugging head of the square tube is pushed into the side channel by the plug-feeding telescopic arm, and the square tube is pushed into the assembly center by the tube-pushing device at the same time. At this time, the plugging head is located at both side ends of the square tube, so that when the plug-pushing telescopic arm is extended, the plugging head can be pre-installed on both ends of the square tube, so that the plugging head can be accurately assembled on both side ends of the square tube.

[0017] (2) In the present invention, the pre-installed square tube with the plugging head continues to move backward and is then squeezed by the plugging telescopic arm, so that it is firmly assembled at both ends of the square tube, thereby improving the yield rate after assembly. In addition, the square tube is first pushed out of the square tube rack and then plugged, which can reduce the wear on the outer wall of the square tube and avoid scratching the square tube.

[0018] (3) In the present invention, the cylinder is set to push the tongue to move in the frame, so that when the square tube passes through the tongue, the tongue can extend to intercept the square tube, thereby controlling the square tubes to fall in sequence. In addition, the two frames cooperate to stack the square tubes in a single row in sequence to reserve a certain number of square tube materials. The number of square tubes stacked in a single row can be controlled to facilitate counting and screening of defective products, and can also reduce the pressure on the lower square tubes to avoid the square tubes being compressed and deformed.

[0019] (4) In the present invention, the curved plugging arm can be directly assembled at the discharge port of the vibrating screen plugging head device, thereby automating the loading work of the plugging head to reduce labor costs and improve processing efficiency.

[0020] (5) In the present invention, the position of the plug pushing device with a single frame and a plug arm can be adjusted by fixing the side plate, so that the spacing between the frames can be suitable for square tubes with different lengths, thereby increasing the application range of the device.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: a square tube plugging plug assembly machine, comprising a square tube rack 1 and a plug pushing device 2, an assembly center 10 is provided directly below the square tube rack 1, and a tube pushing device 3 for pushing the square tube is provided on one side of the assembly center 10, the square tube rack 1 comprises two frame bodies 11 vertically placed in a central symmetric shape, a connecting pipe plate 12 is provided at the bottom of the frame body 11, and a blocking tongue 13 capable of extending between the two frame bodies 11 is provided at the bottom of the frame body 11, and a cylinder 14 for controlling the movement of the blocking tongue 13 is provided on one side of the frame body 11, and the width of the blocking tongue 13 is less than the inner diameter width of the square tube;

[0030] The two frames 11 cooperate to stack the square tubes in sequence to store a certain amount of square tube materials, and the cylinder 14 is used to push the tongue 13 to move in the frame 11, so that when the square tube passes through the tongue 13, the tongue 13 is extended to intercept the square tube, and the tongue 13 is retracted to release the square tube, thereby controlling the square tubes to fall in sequence.

[0031] See also Figures 1 to 6 The tube pushing device 3 includes a tube pushing telescopic arm 30, a pushing plate 31 is provided at the telescopic end of the tube pushing telescopic arm 30, a workbench 4 is provided at the bottom of the square tube rack 1 and the plug pushing device 2, and the square tube rack 1 is located in the center of the workbench 4;

[0032] The push plate 31 of the tube pushing device 3 is located between the two frames 11, so that when the tube pushing telescopic arm 30 pushes the push plate 31 to move, the square tube can be pushed out from the connecting plate 12 to the assembly center 10. The square tube pushing assembly can reduce the squeezing of the square tube by the equipment, thereby avoiding scratches on the square tube material and protecting the square tube material to the greatest extent.

[0033] See also Figures 1 to 6 The plug pushing device 2 is symmetrically arranged on both sides of the assembly center 10. The plug pushing device 2 includes a plug connecting arm 20. The end of the plug connecting arm 20 is provided with a side channel 21 connected to the assembly center 10. The two opposite side ends of the side channel 21 are respectively provided with a fixed plug wall 22 and a plug sending telescopic arm 23 for pushing the plug head. A plug pushing telescopic arm 24 is provided on the side of the side channel 21 away from the assembly center 10. A fixed pipe wall 25 that can move forward and backward is provided on the side of the assembly center 10 away from the square pipe rack 1. A sealing telescopic arm 26 is provided at a position horizontal to the outer wall of the fixed pipe wall 25 on one side of the assembly center 10;

[0034] The curved plugging arm 20 can be directly assembled at the discharge port of the vibrating screen plugging head equipment. The plugging head dropped by the plugging arm 20 is pre-installed on both sides of the square tube by the plugging telescopic arm 23 and the plugging telescopic arm 24. After the square tube is pushed again, the plugging telescopic arm 26 extrude and assembles the square tube with the pre-installed plugging head to complete the installation of the plugging head. The method of pre-installing and then installing can avoid the situation of empty installation and reduce the pressure on the square tube to better protect the square tube.

[0035] See also Figures 1 to 6 A linear track 40 is provided on the workbench 4, and a sliding seat 27 slidably assembled on the linear track 40 is provided at the bottom of the pusher device 2; a fixed side plate 28 is provided on one side of the sliding seat 27, and a plurality of positioning holes 41 are provided at the linear track 40 corresponding to the fixed side plate 28;

[0036] The position of the plug pushing device 2 with a single frame 11 and a plug arm 20 can be adjusted by fixing the side plate 28, so that the spacing between the frames 11 can be suitable for square tubes with different lengths, thereby increasing the application range of the device.

[0037] The working principle and use process of the present invention are as follows: first, directly assemble the plug arm 20 at the discharge port of the vibrating screen plugging head equipment, and use bolts to install the fixed side plate 28 on the positioning hole 41 at the corresponding position on the top of the workbench 4, so that the plug pushing device 2 is installed on the workbench 4. At this time, the distance between the two frames 11 matches the length of the square tube, so that the square tube can be placed in the square tube frame 1, and when placed, the two sides of the square tube with the opening should fit with the two frames 11.

[0038] Subsequently, the square tubes are stacked in sequence to reserve a certain amount of square tube materials. When the tube-pushing telescopic arm 30 pushes the pushing plate 31 to move, the square tube can be pushed out from the connecting plate 12 to the assembly center 10. At this time, the fixed tube wall 25 extends out and abuts against the outer wall of the square tube to prevent the square tube from moving too far. When the square tubes fall in sequence, after the bottom square tube passes through the blocking tongue 13, the cylinder 14 pushes the blocking tongue 13 into the frame 11 and into the side opening of the square tube, or directly inserts into the bottom of the square tube.

[0039] The plugging head guided down by the plug receiving arm 20 is sent to one side of the plug pushing telescopic arm 24. The plug pushing telescopic arm 24 pushes the plugging head, and together with the plugging head, squeezes the square tube in the center. The plug delivering telescopic arm 23 can accurately push the plugging head to one side of the plug pushing telescopic arm 24 and align it with the side opening of the square tube, so that the plug delivering telescopic arm 23 cooperates with the plug pushing telescopic arm 24 to pre-install the plugging head on both sides of the square tube.

[0040] Then, after the tube-pushing telescopic arm 30 pushes the square tube again through the pushing plate 31, the plugging telescopic arm 26 extrude and assembles the square tube pre-installed with the plugging head to complete the installation of the plugging head. The method of pre-installing and then installing can avoid the situation of empty installation and reduce the pressure on the square tube to better protect the square tube.

[0041] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
