Description

Technical Field

[0001] This invention relates to the field of automatic telescopic hose reel technology, and more specifically, to a welding apparatus and method for assembling a high wear-resistant automatic telescopic hose reel. Background Technology

[0002] An automatic telescopic hose reel is a tubular device that can automatically extend or shorten as needed. Inside the hose reel, there is usually a spring or other elastic element, as well as a mechanism for controlling its extension and retraction. When an external force is applied to one end of the hose reel, the spring is compressed or stretched, thereby extending or shortening the hose reel accordingly. When the external force is removed, the spring returns to its original state, causing the hose reel to return to its original length. This device is widely used in various applications where flexible control of pipeline length is required, such as in the automotive, machinery, and aerospace industries, providing great convenience for pipeline storage and management. In the welding device and method of this invention, the automatic telescopic hose reel is one of the core components, and its high wear resistance is crucial to the service life and performance of the entire device.

[0003] According to patent document CN220334386U, an automatic telescopic hose reel includes: a base; two housings are mounted on the upper end of the base; a receiving roller is rotatably connected to the side walls of the two housings; a first limiting plate and a second limiting plate are rotatably connected to the inner walls of the two housings respectively; a first connecting rod and a second connecting rod are respectively mounted on the inner walls of the two housings; a first positioning block and a second positioning block are slidably connected to the outside of the first connecting rod and the second connecting rod; support rods are mounted on the side walls of the two housings; a first crossbar and a second crossbar are spaced apart on the side walls of the two support rods; a threaded rod is rotatably connected to the middle of the first crossbar; a sliding rod is mounted to the middle of the second crossbar; and a threaded block is threadedly connected to the outside of the threaded rod. This structure allows the receiving rollers to be limited during rotation, preventing them from rotating back during hose reeling and unwinding, thus avoiding any impact on the performance.

[0004] After assembling the automatic telescopic hose reel, welding is usually required for some key components to enhance the stability and durability of its overall structure. However, if proper measures are not taken before welding and the automatic telescopic hose reel is placed directly on a table or the ground for welding, it may cause the hose reel to loosen during the welding process. This loosening may cause the assembled components to shift, resulting in misalignment of the welding position. Once the welding position deviates, it may negatively affect the overall performance of the automatic telescopic hose reel. Summary of the Invention

During the welding process, the stability and accuracy of the welding robotic arm are fully guaranteed, ensuring welding quality and efficiency.

[0022] Step 5: After welding is completed, control the reverse rotation of each motor to restore all components to their initial state, making it easy to remove the welded automatic telescopic hose reel and prepare for the next round of welding operations.

[0023] The beneficial effects of this invention are as follows:

[0024] This invention, by incorporating a welding station, clamping components, and an assembly station, achieves a highly automated and intelligent welding process, significantly improving the assembly efficiency and welding precision of high-wear-resistant automatic telescopic hose reels. Through precise mechanical structure design, the coordinated actions between components are accurately controlled, ensuring the stability and reliability of the welding process. Furthermore, this welding device and method possess high flexibility, adapting to the welding needs of automatic telescopic hose reels of different sizes and specifications, further broadening its application scope. The implementation of this invention not only improves production efficiency but also reduces labor costs, effectively solving the problem of loosening of the automatic telescopic hose reel during welding. This loosening may cause displacement of assembled components, leading to misalignment of the welding position. Once the welding position deviates, it may negatively impact the overall performance of the automatic telescopic hose reel. Attached Figure Description

The inner sides of both sets of L-shaped expansion rods 316 extend to the inner sides of the two sliding discs 39 and are fixedly connected to arc-shaped expansion blocks 318. The inner sides of both sets of arc-shaped expansion blocks 318 are fixedly connected to L-shaped clamping rods 319. The assembly table 4 includes a telescopic assembly table 41. The bottom of the telescopic assembly table 41 is slidably connected to the front bottom of the L-shaped horizontal plate 214. The telescopic assembly table 41 is located on the left and right sides. Both sides have push-pull side uprights 42 fixedly connected to their bottoms. Each push-pull Z-shaped rod 43 is fixedly connected to its top. Each push-pull Z-shaped rod 43 has an inverted L-shaped push-pull rod 44 fixedly connected to its rear top. The outer walls of the two inverted L-shaped push-pull rods 44 are slidably connected to the inner walls of the side horizontal plate guide grooves 2124 opened in the two side horizontal plates 2123. The inner tops of the two inverted L-shaped push-pull rods 44 are fixedly connected to both sides of the middle of the outer wall of the push-pull rod 228.

[0039] After the automatic telescopic hose reel is assembled, when welding is required, first open the welding chamber 1 and place the automatic telescopic hose reel on top of the telescopic assembly table 41. Then, start the motor 2118. The motor 2118 drives the transmission disc 2119 to rotate, which in turn drives the track 2120 and the second transmission disc 2121 to rotate. The rotation of the second transmission disc 2121 drives the rotation of the lead screw 2122. Since the inner wall of the push-pull rod 228 is threadedly connected to the outer wall of the lead screw 2122, the push-pull rod 228 will move along its axial direction under the drive of the lead screw 2122. At the same time, the outer wall of the push-pull rod 228 is slidably connected to the guide disc 2. The inner walls of 115 and the second guide plate 2117 ensure the stability of the push-pull rod 228 during movement. When the push-pull rod 228 moves axially to the rear side on the outer wall of the screw 2122, the push-pull rod 228 pulls the hinge block 226 to move to the rear side. The rearward movement of the hinge block 226 then pulls the two rotating rods 225 to rotate. The rotation of the two rotating rods 225 then pulls the two retracting rods 221 to move inward. The inward movement of the two retracting rods 221 then drives the two L-shaped retracting plates 223 to move inward, thereby making the inner sides of the two clamping components 3 gradually approach the outer wall of the automatic telescopic hose reel.

[0040] At the same time, when the push-pull rod 228 moves to the rear, it drives the two inverted L-shaped push-pull rods 44 to move to the rear. The two inverted L-shaped push-pull rods 44 move to the rear, which in turn pulls the two push-pull side uprights 42, causing the telescopic assembly table 41 to move to the rear. The telescopic assembly table 41 causes the automatic telescopic hose reel placed on its top to move to the inside of the two clamping components 3.

[0041] When the automatic telescopic hose reel moves to the inside of the two clamping components 3, the two control motors 33 are activated. The two control motors 33 drive the two second lead screws 34 to rotate. Since the two transmission blocks 35 are threadedly connected to the outer walls of the two second lead screws 34, the two transmission blocks 35 move along their axial direction under the drive of the second lead screws 34. The movement of the two transmission blocks 35 then pulls the two internal gear discs 312 to rotate via the two pull blocks 36. The rotation of the two internal gear discs 312 then, through the gear column connecting rod 314 fixed on both sides of its outer wall... The meshing transmission between gear 315 and rack 317 drives two sets of L-shaped expansion rods 316 to move relative to or away from each other. The movement of the two sets of L-shaped expansion rods 316 further drives two sets of arc-shaped expansion blocks 318 to move relative to or away from each other. The movement of the two sets of arc-shaped expansion blocks 318 further clamps and fixes the outer wall of the automatic telescopic hose reel through the L-shaped clamping rod 319, ensuring the stability of the automatic telescopic hose reel during welding. After clamping is completed, the telescopic assembly table 41 is activated, causing the telescopic assembly table 41 to adjust its height downwards to allow space for the subsequent rotation of the automatic telescopic hose reel.

[0042] During welding, the second motor 2125 can be activated, driving the third transmission disc 2126 to rotate, which in turn drives the second track 2127 and the fourth transmission disc 2128 to rotate. The rotation of the fourth transmission disc 2128 drives the rotation of the right-side cylindrical rotating block 224, which in turn drives the disc 31 and the clamping assembly 3 to rotate, so as to weld different parts of the automatic telescopic hose reel, improving welding efficiency and flexibility. During the welding process, the welding robotic arm 24 can perform precise welding operations on different parts of the automatic telescopic hose reel according to welding requirements. The welding robotic arm 24 is fixedly connected to the control assembly 21 through the welding robotic arm connecting plate 23, ensuring stability and accuracy during the welding process. At the same time, the design of the expansion and contraction assembly 22 allows the clamping assembly 3 to flexibly adjust the clamping range to adapt to automatic telescopic hose reels of different sizes, further improving the versatility and efficiency of welding. The entire welding device, through precise mechanical structure design and motor drive, realizes an automated and highly efficient welding process, greatly improving the production quality and efficiency of the automatic telescopic hose reel.

[0043] In addition, the present invention also relates to a welding apparatus and method for assembling a high wear-resistant automatic telescopic hose reel, comprising the following steps:

[0044] Step 1: After assembling the automatic telescopic hose reel, place it on the telescopic assembly table 41 inside the welding chamber 1, ready for welding operation;

[0045] Step 2: Start motor 2118 and control motor 33, and control the coordinated action of each component according to the preset program. Motor 2118 drives the transmission system, causing lead screw 2122 to rotate, which in turn pushes push rod 228 and its connected components to move linearly. This action simultaneously triggers the retraction and expansion action of retraction and expansion component 22, as well as the backward movement of telescopic assembly table 41, which prepares for the automatic telescopic hose reel to be accurately positioned between clamping components 3.

[0046] Step 3: After the clamping component 3 stably clamps the automatic telescopic hose reel, the telescopic assembly table 41 is raised and lowered to make enough space for the welding operation. At the same time, the second motor 2125 is started to drive the clamping component 3 and the clamped automatic telescopic hose reel to rotate through the transmission system so that the welding robot arm 24 can weld different parts.

[0047] Step 4: The welding robotic arm 24 performs precise welding on various parts of the automatic telescopic pipe reel according to the preset welding path and parameters. During the welding process, the stability and accuracy of the welding robotic arm 24 are fully guaranteed, ensuring welding quality and efficiency.

[0048] Step 5: After welding is completed, control the reverse rotation of each motor to restore all components to their initial state, making it easy to remove the welded automatic telescopic hose reel and prepare for the next round of welding operations.

[0049] Working principle of this invention: First, open the welding chamber 1 and place the automatic telescopic hose reel on top of the telescopic assembly table 41. Then, start the motor 2118. The motor 2118 drives the transmission disc 2119 to rotate, which in turn drives the track 2120 and the second transmission disc 2121 to rotate. The rotation of the second transmission disc 2121 drives the rotation of the lead screw 2122. Since the inner wall of the push-pull rod 228 is threadedly connected to the outer wall of the lead screw 2122, the push-pull rod 228 will move along its axial direction under the drive of the lead screw 2122. At the same time, the outer wall of the push-pull rod 228 is slidably connected to the inner wall of the guide disc 2115 and the second guide disc 2117, ensuring the stability of the push-pull rod 228 during movement. When the push-pull rod 228 moves axially backward on the outer wall of the lead screw 2122... During movement, the push-pull rod 228 pulls the hinge block 226 to move rearward. The rearward movement of the hinge block 226 then pulls the two rotating rods 225 to rotate. The rotation of the two rotating rods 225 then pulls the two retracting rods 221 to move inward. This inward movement of the two retracting rods 221 causes the two L-shaped retracting plates 223 to move inward, thus gradually bringing the inner sides of the two clamping components 3 closer to the outer wall of the automatic telescopic hose reel. Simultaneously, when the push-pull rod 228 moves rearward, it causes the two inverted L-shaped push-pull rods 44 to move rearward. The two inverted L-shaped push-pull rods 44 then pull the two push-pull side uprights 42, causing the telescopic assembly platform 41 to move rearward. The telescopic assembly platform 41 then moves the automatic telescopic hose reel placed on its top. When the automatic telescopic hose reel moves to the inside of the two clamping components 3, the two control motors 33 are activated. The two control motors 33 drive the two second lead screws 34 to rotate. Since the two transmission blocks 35 are threaded to the outer walls of the two second lead screws 34, the two transmission blocks 35 will move along their axial direction under the drive of the second lead screws 34. The movement of the two transmission blocks 35 will then pull the two internal gear turntables 312 to rotate through the two pull blocks 36. The rotation of the two internal gear turntables 312 will then drive the two sets of L-shaped retracting and expanding rods 316 to move relative to each other or in opposite directions through the meshing of the gears 315 and rack rods 317 fixed on both sides of the outer wall of the gear column connecting short rod 314. The movement of the two sets of L-shaped retracting and expanding rods 316 will then drive the two sets of L-shaped retracting and expanding rods 316 to move relative to each other or in opposite directions. Two sets of arc-shaped expansion and contraction blocks 318 move relative to or away from each other. These blocks move and, through the L-shaped clamping rods 319, clamp and fix the outer wall of the automatic telescopic hose reel, ensuring its stability during welding. After clamping, the telescopic assembly table 41 is activated, adjusting its height downwards. During welding, the second motor 2125 is activated, driving the third transmission disc 2126 to rotate, which in turn drives the second track 2127 and the fourth transmission disc 2128 to rotate. The rotation of the fourth transmission disc 2128 causes the right-side cylindrical rotating block 224 to rotate, which in turn drives the disc 31 and the clamping assembly 3 to rotate, thus welding different parts of the automatic telescopic hose reel.During the welding process, the welding robotic arm 24 performs precise welding operations on different parts of the automatic telescopic hose reel according to the welding requirements.
