Description

Technical Field

[0001] This utility model relates to the field of round tube and bushing welding technology, specifically a bushing removal structure for a round tube and bushing welding production line. Background Technology

[0002] Welded round tube bushings are mainly used in scenarios that require torque transmission, load bearing, or precise positioning. Welded round tube bushings can achieve local functional enhancement and save materials to reduce costs.

[0003] Before welding the round tube and the bushing, the round tube and the bushing need to be assembled. Currently, in the welding production line of the round tube and the bushing, the round tube needs to be changed frequently and the bushing needs to be picked up. Picking up the bushing mainly relies on manual labor. Since the welding process is fast, workers need to wait at the welding point to finish welding before picking up the bushing and assembling it with the round tube. The labor cost is high and the efficiency is low. Workers are in the welding environment for a long time, and harmful gases, high temperature noise and radiation affect the physical and mental health of the workers. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a bushing picking structure for a round tube and bushing welding production line. This device solves the problems of high labor costs and low efficiency in workers picking bushings and assembling round tubes.

[0005] To solve the above problems, the following technical solutions are provided: This utility model discloses a bushing removal structure for a circular tube and bushing welding production line, comprising: A picking component, the picking component including a top sleeve shaft that is slidably disposed in a horizontal direction; The feeding assembly includes a bushing frame, a second slide table and a lifting mechanism sequentially disposed at the bottom end of the bushing frame, the output shaft of the lifting mechanism being connected to the bottom end of the second slide table, the lifting mechanism driving the second slide table and the bushing frame to move vertically, and the second slide table driving the bushing frame to move horizontally towards or away from the top sleeve shaft; A rolling bushing is placed on the bushing holder, and the top bushing shaft can be inserted into the bushing for removing the bushing.

[0006] The above solution, through the setup of the component retrieval and loading components, allows the elevator to move the second slide and bushing frame vertically until the bushing and the top sleeve shaft are on the same plane. The second slide then moves the bushing frame closer to the top sleeve shaft until the bushing and the top sleeve shaft are concentric. The retrieval component moves closer to the bushing frame, and the top sleeve shaft inserts into the bushing, allowing the bushing to fit onto the top sleeve shaft. At this point, the bushing frame, driven by the second slide and the elevator, leaves the top sleeve shaft, which then moves the bushing further until it is assembled with the round tube. The bushing retrieval process requires no manual intervention, reducing labor costs, protecting the physical and mental health of workers, and achieving high assembly accuracy without the need for manual assembly, thus improving welding efficiency.

[0007] Furthermore, it also includes: a first slide table, in which a first motor and a first lead screw are disposed along its axial direction, and the output shaft of the first motor is coaxially connected to the first lead screw; The picking component also includes a sliding plate connected to one end of the top sleeve shaft. The top sleeve shaft is sleeved on the first lead screw via the sliding plate. The top sleeve shaft is arranged parallel to the first lead screw. The first slide table drives the top sleeve shaft to move along its axial direction.

[0008] The above solution, through the setting of the first slide table, the first motor drives the first lead screw to rotate, causing the top sleeve shaft to move horizontally on the first lead screw, thereby fitting the sleeve and driving the sleeve assembly. The top sleeve shaft reciprocates in the horizontal direction, thereby realizing multiple sleeve removals, eliminating the need for manual removal of the sleeve and the round tube assembly, and improving welding efficiency and accuracy.

[0009] Furthermore, a plurality of top blocks with gradually decreasing diameters are sequentially arranged on the other end of the top sleeve shaft, and the plurality of top blocks are all cylindrical; Multiple bushings are provided, and the diameter of each bushing is equal to the inner diameter of each top block.

[0010] The above solution uses top blocks to accommodate bushings of different diameters, as different diameter round pipes need to be welded to bushings of different diameters. Multiple top blocks of different diameters are matched with bushings of different diameters, so that the bushings can be fitted onto the top blocks and adapt to various bushings.

[0011] Furthermore, the bushing bracket is provided with an inclined plate, the bottom end of the inclined plate is close to the top bushing shaft, and multiple bushings are placed on the inclined plate; The bushing frame has an opening on the side near the top sleeve shaft, and the top sleeve shaft can pass through the opening and the bushing in sequence.

[0012] The above solution uses a bushing bracket to allow the bushing to roll on the inclined plate to the opening under its own weight. The top bushing shaft then extends into the bushing from the opening. After the bushing assembly is removed, the next bushing rolls to the opening to facilitate the removal of the top bushing shaft.

[0013] Furthermore, the second slide table is provided with a second motor and a second lead screw arranged along its axial direction, and the output shaft of the second motor is coaxially connected to the second lead screw; The bottom end of the bushing frame is sleeved on the second lead screw, the second lead screw is arranged parallel to the bushing frame, and the second slide table drives the bushing frame to move in a direction perpendicular to the axis of the top sleeve shaft.

[0014] The above solution uses a second slide table, a second motor to drive the second lead screw to rotate, and a bushing frame to slide on the second lead screw, thereby moving the bushing closer to or away from the top sleeve shaft, so that the bushing is concentric with the top sleeve shaft and is fitted onto the top sleeve shaft, thus realizing the removal of the bushing.

[0015] Furthermore, vertical guide shafts are provided on both sides of the elevator, and the top end of the guide shafts is connected to the bottom end of the second slide.

[0016] The above solution improves structural stability by using a guide shaft, which provides guidance and support, allowing the elevator to move the second slide and bushing frame vertically.

[0017] Furthermore, an oiler is provided on the sliding plate, and the oiler is connected to the interior of the first slide table. The oiler is used for lubricating the first slide table.

[0018] The above solution uses an oiler to lubricate the first slide, ensuring efficient removal of the top sleeve shaft.

[0019] Furthermore, it also includes: a base, wherein the picking component is connected to the top of the base via the first slide; The feeding assembly also includes a support frame, which is connected to the side wall of the base. The lifting machine is mounted on the support frame, and the guide shaft slides on the support frame.

[0020] The above solution uses a base to house both the picking and feeding components, providing support for them and improving their stability.

[0021] The above solution has the following advantages: The bushing picking structure of this utility model, which is a round tube and bushing welding production line, includes a picking component, a feeding component, a first slide table that drives the picking component to move, and a base connected to the picking component and the feeding component. The bushings are placed on the bushing frame in sequence according to the round tubes to be welded. The displacement of the picking component and the feeding component is set. The lifting device drives the second slide table and the bushing frame to move vertically, so that the axis of the bushing and the axis of the top sleeve shaft are in the same plane. The second motor drives the second lead screw to rotate, thereby causing the bushing frame to slide closer to the second lead screw. The top sleeve shaft is moved until the sleeve and the top sleeve shaft are concentric. Under its own weight, the sleeve slides down to the opening. The first motor drives the first lead screw to rotate, so that the top sleeve shaft slides on the first lead screw and approaches the sleeve. The top sleeve shaft is inserted into the sleeve so that the sleeve is fitted onto the top sleeve shaft. The second slide and the elevator drive the sleeve frame away from the pick-up component. The top sleeve shaft continues to move with the sleeve to complete the assembly of the sleeve and the round tube. Repeat the above steps to complete the automatic feeding of the sleeve on the production line of round tube and sleeve. It is highly accurate and efficient without the need for manual assistance, and protects workers from the harm of the welding environment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, the present invention discloses a bushing picking structure for a round tube and bushing welding production line, comprising: picking component 1, feeding component 2 and base 4. Both picking component 1 and feeding component 2 are mounted on base 4. Picking component 1 is used to pick up bushing 211, and feeding component 2 is used to transport bushing 211 to picking component 1.

[0026] Among them, such as Figure 3 As shown, the picking component 1 includes a top sleeve shaft 11 that slides horizontally. Multiple top blocks 111 with gradually decreasing diameters are sequentially arranged on the other end of the top sleeve shaft 11. All top blocks 111 are cylindrical. Multiple bushings 211 are provided, and the diameter of each bushing 211 is equal to the inner diameter of each top block 111. Multiple top blocks 111 with different diameters are matched with bushings 211 with different diameters, so that the bushings 211 can be fitted onto the top blocks 111, thereby adapting to various bushings 211.

[0027] It should be noted that the picking component 1 is connected to the top of the base 4 via the first slide 3. The first slide 3 is provided with a first motor 31 and a first lead screw 32 along its axial direction. The output shaft of the first motor 31 is coaxially connected with the first lead screw 32. The picking component 1 also includes a sliding plate 12 connected to one end of the top sleeve shaft 11. The top sleeve shaft 11 is sleeved on the first lead screw 32 via the sliding plate 12. The top sleeve shaft 11 is arranged parallel to the first lead screw 32. The first slide 3 drives the top sleeve shaft 11 to move along its axial direction. An oiler 13 is provided on the sliding plate 12. The oiler 13 is in communication with the inside of the first slide 3 and is used for lubricating the first slide 3.

[0028] In this embodiment, the first motor 31 drives the first lead screw 32 to rotate, causing the top sleeve shaft 11 to move horizontally on the first lead screw 32, thereby fitting the bushing 211 and driving the bushing 211 to be assembled. The top sleeve shaft 11 reciprocates in the horizontal direction, thereby realizing multiple picking and unpicking of the bushing 211 without the need for manual picking of the bushing 211 and the round tube assembly, thus improving welding efficiency and accuracy.

[0029] like Figure 4As shown, the feeding assembly 2 includes a bushing frame 21, a second slide 22 arranged sequentially at the bottom of the bushing frame 21, and a lifting mechanism 23. The output shaft of the lifting mechanism 23 is connected to the bottom of the second slide 22. The lifting mechanism 23 drives the second slide 22 and the bushing frame 21 to move in the vertical direction, and the second slide 22 drives the bushing frame 21 to move in the horizontal direction close to or away from the top sleeve shaft 11. In this embodiment, a rolling bushing 211 is placed on the bushing frame 21, and a top sleeve shaft 11 can be inserted into the bushing 211 for retrieving the bushing 211. An inclined plate 212 is provided on the bushing frame 21, with the bottom end of the inclined plate 212 close to the top sleeve shaft 11, and multiple bushings 211 are placed on the inclined plate 212. An opening 213 is provided on the side of the bushing frame 21 close to the top sleeve shaft 11, and the top sleeve shaft 11 can pass through the opening 213 and the bushing 211 in sequence. Under its own weight, the bushing 211 rolls on the inclined plate 212 to the opening 213, and the top sleeve shaft 11 extends into the bushing 211 from the opening 213. After the bushing 211 is removed and assembled, the next bushing 211 rolls to the opening 213 for the top sleeve shaft 11 to continue to retrieve.

[0030] like Figure 5 As shown, a second motor 221 and a second lead screw 222 are arranged inside the second slide table 22 along its axial direction. The output shaft of the second motor 221 is coaxially connected to the second lead screw 222. The bottom end of the bushing frame 21 is sleeved on the second lead screw 222. The second lead screw 222 is arranged parallel to the bushing frame 21. The second slide table 22 drives the bushing frame 21 to move in a direction perpendicular to the axis of the top sleeve shaft 11. The second motor 221 drives the second lead screw 222 to rotate, and the bushing frame 21 slides on the second lead screw 222, thereby driving the bushing 211 to move closer to or away from the top sleeve shaft 11, so that the bushing 211 is concentric with the top sleeve shaft 11 and sleeved on the top sleeve shaft 11, realizing the removal of the bushing 211.

[0031] In addition, vertical guide shafts 24 are provided on both sides of the elevator 23, and the top of the guide shaft 24 is connected to the bottom of the second slide 22. The guide shaft 24 provides guidance and support, so that the elevator 23 drives the second slide 22 and the bushing frame 21 to move in the vertical direction, thereby improving the stability of the structure.

[0032] The feeding assembly 2 also includes a support frame 25, which is connected to the side wall of the base 4. The elevator 23 is mounted on the support frame 25, and the guide shaft 24 slides on the support frame 25.

[0033] During operation, the bushings 211 are placed on the bushing holder 21 in sequence according to the round pipes to be welded. The bushing 211 closest to the picking component 1 slides down to the opening 213 under the action of the inclined plate 212. The displacement of the picking component 1 and the feeding component 2 is set. The lifting device 23 drives the second slide table 22 and the bushing holder 21 to move vertically, so that the axis of the bushing 211 is at the same height as the axis of the top sleeve shaft 11. The second motor 221 drives the second lead screw 222 to rotate, so that the bushing holder 21 slides on the second lead screw 222 closer to the top sleeve shaft 11 until the bushing 211 is concentric with the top sleeve shaft 11. The first motor 31 drives... The first lead screw 32 rotates, causing the top sleeve shaft 11 to slide on the first lead screw 32 and approach the bushing 211. The top sleeve shaft 11 is inserted into the bushing 211, so that the bushing 211 is fitted onto the top sleeve shaft 11. The elevator 23 drives the second slide table 22 and the bushing frame 21 to descend, causing the bushing frame 21 to leave the top sleeve shaft 11. The second slide table 22 then drives the bushing frame 21 away from the pick-up component 1. The top sleeve shaft 11 continues to move with the bushing 211 to achieve the assembly of the bushing 211 and the round tube. After the assembly is completed, the first slide table 3 drives the top sleeve shaft 11 back to its original position. Repeat the above steps to complete the automatic feeding of the bushing 211 on the production line of the round tube and the bushing 211.
