Description

Technical Field

[0001] This utility model relates to the field of automatic welding equipment technology, and in particular to a door handle end cap rotary welding equipment. Background Technology

[0002] Door handles come in various forms, with square and round tube handles, known for their simple and elegant design, enjoying a large market share. Regardless of the style, door handles typically require cutting long strips of square or round tube into suitable lengths during manufacturing, followed by sealing both ends with end caps. The most common sealing method is welding. Existing welding methods include manual and automatic welding. In manual welding, workers place the end caps on the blank and then weld them using a welding device. In automatic welding, workers fix the blank onto the automatic welding equipment, secure the end caps, and the equipment then performs the welding automatically.

[0003] To ensure a more uniform weld, the fixture on the automatic welding equipment rotates the blank during welding. The distance from the edge of the round tube blank to the center line of the rotating shaft is relatively uniform, allowing the welding operation to be completed evenly as the fixture rotates. However, the distance between the edge of the square tube blank and the center line of the rotating shaft varies, causing the distance between the weld point and the center line of the rotating shaft to constantly change, which inevitably affects the welding efficiency and accuracy. Furthermore, existing automatic welding equipment typically uses a three-rotor chuck fixture, which is time-consuming when picking up and placing parts.

[0004] Therefore, there is a need for an automatic welding equipment for welding square tube blanks, which can improve the welding accuracy of square tube blanks and end caps and save the time of picking up and placing parts. Utility Model Content

[0005] The purpose of this invention is to provide a door handle end cap rotary welding device, which aims to solve the problems of low precision and time-consuming part picking and placing when welding square tube blanks and end caps with existing automatic welding equipment.

[0006] To achieve the above objectives, this utility model provides a door handle end cap rotary welding device, including a support, a clamping assembly, a positioning assembly, and a welding assembly. The clamping assembly includes a base, a rotating seat, a base plate, and a slide table. The base is fixedly installed on the support, and a rotating seat is installed on one side of the base. A rotating sleeve and a rotary motor are installed on the rotating seat. The rotary motor is installed on the rotating seat and is used to drive the rotating sleeve to rotate on the rotating seat. A base plate is fixedly installed on the rotating sleeve and can rotate together with the rotating sleeve. A slide table is provided on the base plate, and a sliding cylinder is installed on the base plate. The sliding cylinder is used to drive the slide table to slide on the base plate. A retaining seat is provided at both ends of the slide table, and a front clamp and a rear clamp are provided on the base plate. The front clamp and the rear clamp correspond to the retaining seats on the slide table.

[0007] The positioning component is installed at the end of the base away from the rotating seat. The positioning component is used to position the square tube blank, and the welding component is used to weld the square tube blank on the clamping component.

[0008] Furthermore, the front clamp includes a clamping cylinder, which is mounted on the front of the slide table via a bracket; the rear clamp includes a pressure plate and a lifting cylinder, which is mounted on the base and is used to drive the pressure plate closer to or further away from the rear of the slide table.

[0010] Furthermore, the positioning component includes a positioning cylinder, a positioning block, a limiting cylinder, and a limiting block. The positioning cylinder is mounted on the end of the base away from the rotating seat via a support frame, and is used to drive the positioning block to move closer to or away from the slide table. The limiting block is mounted on the positioning cylinder, and a limiting post is provided on the limiting block, with the limiting post facing the slide table. The limiting cylinder is mounted on the base via a support frame, and is located between the positioning cylinder and the slide table.

[0011] Furthermore, the welding assembly includes a lifting guide rail, a transverse guide rail, and a laser welder. The lifting guide rail is mounted on a support and is used to drive the transverse guide rail to rise or fall. The laser welder is mounted on the transverse guide rail and is used to drive the laser welder to move closer to or away from the lifting guide rail.

[0012] Furthermore, the card holder can be detachably mounted on the slide table, and the card holder is provided with a locking groove.

[0013] Furthermore, a pedal switch is installed on the support.

[0014] Furthermore, a through hole is provided in the rotating sleeve.

[0031] The present invention will be described in detail below with reference to specific embodiments.

[0032] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0033] like Figures 1 to 9 As shown, this utility model provides a door handle end cap rotary welding device, including a support 1. The support 1 is equipped with a clamping assembly 2, a positioning assembly 3, and a welding assembly 4. The clamping assembly 2 includes a base 20, a rotating seat 21, a base plate 22, and a slide table 23. The base 20 is fixedly mounted on the support 1. The rotating seat 21 is mounted on one side of the base 20. The rotating seat 21 is equipped with a rotating sleeve 211 and a rotary motor 210. The rotary motor 210 is mounted on the rotating seat 21 and is used to drive the rotating sleeve... 211 rotates on the rotating base 21; a base plate 22 is fixedly mounted on the rotating sleeve 211, and the base plate 22 can rotate together with the rotating sleeve 211. A slide table 23 is provided on the base plate 22, and a sliding cylinder 230 is mounted on the base plate 22. The sliding cylinder 230 is used to drive the slide table 23 to slide on the base plate 22; a retaining seat 24 is provided at both ends of the slide table 23, and a front clamp 25 and a rear clamp 26 are provided on the base plate 22. The front clamp 25 and the rear clamp 26 correspond to the retaining seat 24 on the slide table 23, respectively.

[0034] The positioning component 3 is installed at the end of the base 20 away from the rotating seat 21. The positioning component 3 is used to position the square tube blank, and the welding component 4 is used to weld the square tube blank on the clamping component 2.

[0035] With the above design scheme, the front clamp 25 and the rear clamp 26 cooperate with the card seat 24 to fix the square tube blank. During welding, the rotary motor 210 will drive the square tube blank to rotate through the rotating sleeve 211. Under the drive of the sliding cylinder 230, the slide table 23 can drive the square tube blank to move closer to or away from the positioning component 3, so that the part to be welded is aligned with the welding component 4.

[0036] In this embodiment, the front clamp 25 includes a clamping cylinder 250, which is mounted on the card seat 24 at the front end of the slide table 23 via a bracket; the rear clamp 26 includes a pressure plate 261 and a lifting cylinder 262, which is mounted on the base 20 and is used to drive the pressure plate 261 to move closer to or away from the card seat 24 at the rear end of the slide table 23.

[0037] In this embodiment, the lifting cylinder 262 is provided with a rotating part 260, and the rotating part 260 is provided with a steering groove 263, which is used to rotate the pressure plate 261 by 90°.

[0038] With the above design scheme, when it is necessary to pick up and put down square tube blanks, the lifting cylinder 262 and the clamping cylinder 250 can quickly raise or lower, and quickly loosen or lock the square tube blanks. When it is necessary to remove the welded square tube door handle, the lifting cylinder 262 controls the pressure plate 261 to rise. Under the control of the turning groove 263 in the rotating sleeve 211, the pressure plate 261 is raised to a certain height and then rotated at a certain angle, so that the pressure plate 261 leaves the card seat 24. At the same time, the clamping cylinder 250 is raised, which makes it convenient for the staff to remove the square tube door handle from the card seat 24 and place the square tube blank to be welded. After the square tube blank is placed on the card seat 24, the lifting cylinder 262 and the clamping cylinder 250 start synchronously to clamp the square tube blank.

[0039] As the lifting cylinder 262 deflects during the process of driving the pressure plate 261 to rise, the pressure plate 261 moves away from the top of the card holder 24, and at the same time the rising clamping cylinder 250 will also leave enough space to facilitate the staff to quickly pick up and put away.

[0040] In this embodiment, the positioning component 3 includes a positioning cylinder 30, a positioning block 31, a limiting cylinder 34, and a limiting block 32. The positioning cylinder 30 is mounted on the end of the base 20 away from the rotating seat 21 via a support frame 35. The positioning cylinder 30 is used to drive the positioning block 31 to move closer to or away from the slide table 23. The limiting block 32 is mounted on the positioning cylinder 30 and is provided with a limiting post 33, which faces the slide table 23. The limiting cylinder 34 is mounted on the base 20 via the support frame 35 and is located between the positioning cylinder 30 and the slide table 23.

[0041] With the above design scheme, when it is necessary to position the square tube blank and the end cap, the limiting post 33, the limiting block 32 and the limiting cylinder 34 cooperate to form a positioning point. The user only needs to place the end cap on the limiting post 33, and with the help of the positioning block 31 and the limiting cylinder 34, make the end cap and the square tube blank fit together completely. Then push the square tube blank to make it fit tightly against the end cap. Then the limiting cylinder 34 descends, and the positioning cylinder 30 controls the positioning block 31 to move away from the slide table 23 to avoid interference between the square tube blank and the end cap when flipping. During welding, only the limiting post 33 keeps abutting against the end cap to prevent the end cap from shifting during welding.

[0042] In this embodiment, the welding assembly 4 includes a lifting guide rail 40, a transverse guide rail 41, and a laser welder 42. The lifting guide rail 40 is mounted on the support 1 and is used to drive the transverse guide rail 41 to rise or fall. The laser welder 42 is mounted on the transverse guide rail 41 and is used to drive the laser welder 42 to move closer to or away from the lifting guide rail 40.

[0043] In this embodiment, both the lifting guide rail 40 and the transverse guide rail 41 are powered guide rails, and both the lifting guide rail 40 and the transverse guide rail 41 are equipped with lead screws and servo motors.

[0044] With the above design scheme, driven by the servo motor and the lead screw, the laser welder 42 can always maintain the position consistent with the welding point. Since the length and width of the square tube blank are different, when welding is required, the clamping component 2 controls the surface to be welded to face upward, and the transverse guide rail 41 drives the laser welder 42 to move along the welding direction to complete the welding operation on one side. After the welding work on one side is completed, the rotary motor 210 drives the square tube blank to rotate 90 degrees through the rotating sleeve 211, so that the part to be welded on the other side faces upward. According to the difference between the length and width of the square tube blank, the lifting guide rail 40 controls the laser welder 42 to rise or fall by the corresponding distance to ensure that the position of the welding point is consistent with the height of the laser welder 42.

[0045] In this embodiment, the card holder 24 is detachably mounted on the slide table 23, and the card holder 24 is provided with a locking groove 240.

[0046] With the above design scheme, the staff can install the corresponding model of the card holder 24 according to different models of products. The clamping groove 240 on the card holder 24 can directly clamp the square tube blank, which makes it convenient for the staff to quickly position and place it. At the same time, the clamping groove 240 can also restrict the square tube blank and prevent the square tube blank from shifting during the welding process.

[0047] In this embodiment, a pedal switch 10 is provided on the support 1, which is used to start the welding process.

[0048] In this embodiment, the rotating sleeve 211 is provided with a through hole 212, which allows the square tube blank to pass through easily, ensuring that the equipment can adapt to square tube blanks of different lengths.

[0049] The door handle end cap rotary welding equipment provided by this utility model, compared with the prior art, when square tube blanks need to be welded, the rotary motor 210 drives the square tube blanks on the clamping seat 24 to rotate 90 degrees in sequence. At the same time, under the drive of the lifting guide rail 40 and the transverse guide rail 41, the distance between the laser welder 42 and the welding point is always kept consistent, ensuring welding accuracy. The clamping seat 24 and the positioning component 3 can position and place the square tube blanks and end caps, and then the front clamp 25 and the rear clamp 26 quickly clamp them, improving the picking and placing efficiency.

[0050] Where there is no conflict, the above embodiments and features can be combined with each other.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
