[0014] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0015] 1. This handheld sweeper water tank positioning welding device, when in use, drives the telescopic device 2 to make the clamping block 1 and the clamping block 2 clamp the sweeper water tank to be positioned just below the welding gun, and the welding gun is used to weld the top of the sweeper water tank.

[0016] 2. This handheld sweeper water tank positioning welding device, when in use, after the sweeper water tank welding work is completed, the telescopic rod of the driving telescopic device 2 is slowly retracted to the shortest position and reset. Since the limit plate is still in the vibration space, the spring 1 cannot be reset. However, when the clamping block 1 is just separated from the sweeper water tank, the spring 1 will stretch a distance, causing the folding plate to hit the limit plate, thereby causing the clamping block 2 to vibrate, and then causing the sweeper water tank to vibrate, making it easier for the sweeper water tank to fall onto the conveying device through the discharge hole, thereby improving the reliability of the device.

[0017] 3. This handheld sweeper water tank positioning welding device, when in use, first insert the sweeper water into the inner side of the gear ring. Since the spring 1 is not subjected to external force at this time, the top of the sweeper water tank is in close contact with the wire brush 1 and the wire brush 2. The driving slide rail makes the support frame move horizontally to the right. The support frame drives multiple spheres through the gap between the arc surfaces of the two semi-cylinders, so that the wire brush 1 and the wire brush 2 reciprocate to brush the top of the sweeper water tank to remove rust, thereby meeting the rust removal and cleaning requirements before welding the top of the sweeper water tank.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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.

[0028] The present invention will be further described below in conjunction with the embodiments.

[0029] Example: See Figure 1-Figure 8 The present invention provides a technical solution: a handheld sweeper water tank positioning welding device, comprising a frame 1, one side of a positioning plate 2 is fixedly connected to the frame 1, and a discharge hole 21 is opened on the positioning plate 2. After welding, the sweeper water tank can fall onto a conveying device 7 through the discharge hole 21.

[0030] The frame 1 is connected with a welding assembly 3 for welding the top of the water tank of the sweeper. The welding assembly 3 includes a telescopic device 31, a welding gun 32, a limit plate 33 and a connecting plate. The telescopic device 31 can be a hydraulic telescopic rod or an electric telescopic rod. The telescopic device 31 is fixedly mounted on the frame 1 through a horizontal plate, and the telescopic rod of the telescopic device 31 is vertically arranged downward. The connecting plate is arranged horizontally, and the upper surface of the connecting plate is fixedly connected to the end of the telescopic rod of the telescopic device 31. The welding gun 32 is fixedly mounted on the lower surface of the connecting plate, and the welding gun 32 is located directly above the feed hole 21. Two limit plates 33 are symmetrically arranged, and the limit plates 33 are arranged vertically, and the top of the limit plates 33 is fixedly connected to the lower surface of the connecting plate.

[0031] A positioning clamping assembly 4 is connected to the positioning plate 2 for positioning the sweeper water tank just below the welding gun 32 and allowing the sweeper water tank to automatically drop through the discharge hole 21 . The positioning clamping assembly 4 includes a clamping part 1 41 and a clamping part 2 42 .

[0032] The clamping part 1 41 includes a telescopic device 2 411, a clamping block 1 412 and a concave surface 1 4121. The telescopic device 2 411 can be a hydraulic telescopic rod or an electric telescopic rod, and the telescopic device 2 411 is fixedly mounted on the upper surface of the positioning plate 2 through a mounting block, and the telescopic rod of the telescopic device 2 411 is horizontally arranged.

[0033] The end of the telescopic rod of the telescopic device 411 is fixedly connected to the clamping block 412 through a vertical plate. The clamping block 412 is symmetrically arranged with two clamping blocks 412. The clamping block 412 is provided with a concave surface 4121 that can be tightly attached to the outer surface of the water tank of the sweeper. The surface of the concave surface 4121 can also be provided with an anti-skid groove to increase friction, so as to facilitate clamping the water tank of the sweeper.

[0034] The second clamping part 42 includes a second clamping block 421 , a second concave surface 4211 , a notch groove 4212 , a spring 422 , a column 423 , a mounting groove 424 , an annular plate 425 , a gear ring 426 , an elastic member 427 , a folding plate 428 and a vibration space 429 .

[0035] The second clamping block 421 is provided with a second concave surface 4211 which can be closely attached to the outer surface of the water tank of the sweeper. The surface of the second concave surface 4211 can also be provided with a second anti-skid groove to increase friction, so as to facilitate clamping of the water tank of the sweeper.

[0036] The bottom of the column 423 is fixedly connected to the upper surface of the positioning plate 2. The spring 1 422 is arranged horizontally, one end of the spring 1 422 is fixedly connected to the clamping block 2 421, and the other end of the spring 1 422 is fixedly connected to the column 423.

[0037] The clamping block 421 is provided with a mounting groove 424 and a notch groove 4212. The top inner wall and the bottom inner wall of the mounting groove 424 are fixedly connected with an annular plate 425. A gear ring 426 is rotatably installed between the two annular plates 425. The outer circumferential surface of the gear ring 426 is provided with a tooth opening. The inner circumferential surface of the gear ring 426 is evenly provided with a plurality of elastic members 427. The elastic member 427 can be set to a hollow annular structure. The elastic member 427 can be made of an elastic rubber material and can elastically squeeze the outer circumferential surface of the water tank of the sweeper.

[0038] When the water tank of the sweeping machine is placed inside the gear ring 426, the clamping block 421 and the elastic member 427 will fit tightly with the water tank of the sweeping machine, and the elastic member 427 will rotate together with the gear ring 426. When the elastic member 427 rotates, due to the resistance of the water tank of the sweeping machine, the elastic member 427 will elastically squeeze the circumferential outer side surface of the water tank of the sweeping machine. Under the friction force between the elastic member 427 and the circumferential outer side surface of the water tank of the sweeping machine, the water tank of the sweeping machine will also rotate, but the rotation speed of the water tank of the sweeping machine will be lower than the rotation speed of the gear ring 426.

[0039] Two folding plates 428 are symmetrically arranged on one side of the clamping block 421 near the spring 1 422. The folding plates 428 are L-shaped structures. A vibration space 429 is formed between each folding plate 428 and the clamping block 421. When the vibration space 429 is located directly below the limit plate 33, the limit plate 33 is inserted into the vibration space 429 when the drive retractor 1 31 extends downward. When the limit plate 33 is inserted into the vibration space 429, there is a certain gap between the limit plate 33 and the folding plate 428.

[0040] A cleaning assembly 5 for cleaning the top of the water tank of the sweeper is connected to the frame 1. The cleaning assembly 5 includes a driving part 51 and a cleaning part 52. The driving part 51 includes a slide rail 511, a support frame 512, a supporting rod 513, a ball 514 and a rack 515.

[0041] The slide rail 511 can be an electric slide rail. The slide rail 511 is fixed to the frame 1 through a cross bar set on the upper side thereof. The support frame 512 is slidably installed on the slide rail 511 through a slider set on the top thereof. The slide rail 511 drives the support frame 512 to reciprocate horizontally. A plurality of supporting round rods 513 are fixedly connected to the support frame 512. The supporting round rods 513 are vertically arranged. A ball 514 is rotatably installed on the outer surface of the central circumference of each supporting round rod 513. Each ball 514 has a certain horizontal spacing, and the ball 514 can rotate. A rack 515 is fixedly connected to one side of the support frame 512. The rack 515 is horizontally arranged. The rack 515 moves through the notch groove 4212. The rack 515 is meshed with the teeth on the gear ring 426. When the support frame 512 moves horizontally, it will drive the rack 515 to move horizontally, thereby driving the gear ring 426 to rotate, thereby driving the water tank of the sweeper to rotate.

[0042] The cleaning part 52 comprises a connecting rod 521, a reciprocating part 522, a wire brush 1 523 and a wire brush 2 524. The connecting rod 521 is arranged horizontally, and one end of the connecting rod 521 is fixedly connected to the frame 1.

[0043] The reciprocating part 522 includes a semi-cylinder 5221 and a moving plate 5222. Two reciprocating parts 522 are arranged opposite to each other and are connected to the bottom of the connecting rod 521. A wire brush 1 523 is fixedly connected to the bottom of the moving plate 5222 on one of the reciprocating parts 522, and a wire brush 2 524 is fixedly connected to the bottom of the moving plate 5222 on the other reciprocating part 522. The arc surfaces of the semi-cylinders 5221 on the two reciprocating parts 522 are arranged opposite to each other with a certain gap.

[0044] Wire brush 1 523 is made of steel wires of different specifications, and has a certain hardness and toughness, and is suitable for removing rust from the uneven top surface of the water tank of the sweeper. Wire brush 2 524 is made of steel wires of different specifications, and has a certain hardness and toughness, and is suitable for removing rust from the uneven top surface of the water tank of the sweeper. Wire brush 1 523 and wire brush 2 524 have a certain horizontal spacing, which can prevent wire brush 1 523 and wire brush 2 524 from being entangled during the reciprocating brushing process.

[0045] When the spring 1 422 is not subjected to external force, the toothed ring 426 is located directly below the wire brush 1 523 and the wire brush 2 524. When the sweeper water tank is placed inside the toothed ring 426, the bristles of the wire brush 1 523 and the wire brush 2 524 are in close contact with the top of the sweeper water tank. In this embodiment, the clamping block 2 421 can be pulled to compress the spring 1 422, and then the sweeper water tank is inserted into the inner side of the toothed ring 426, and the elastic member 427 is in close contact with the outer circumferential surface of the sweeper water tank. At this time, the bottom of the sweeper water tank is in contact with the upper surface of the positioning plate 2, and then the clamping block 2 421 is released to reset the spring 1 422, so that the top of the sweeper water tank is in close contact with the bristles of the wire brush 1 523 and the wire brush 2 524. After pulling the clamping block 421, the sweeper water tank is inserted into the inner side of the gear ring 426. An automated device can also be set to operate the clamping block 421 and the sweeper water tank. The reciprocating part 522 also includes a moving rod 5223, a positioning rod 5224, a fixing plate 5225, and a spring 5226. The moving rod 5223 is arranged horizontally, one end of the moving rod 5223 is fixedly connected to the vertical surface of the semi-cylinder 5221, and the other end of the moving rod 5223 is fixedly connected to the moving plate 5222.

[0046] The positioning rod 5224 is vertically arranged, the top of the positioning rod 5224 is fixedly connected to the lower surface of the connecting rod 521, and a through hole is provided on the positioning rod 5224, and the moving rod 5223 can move horizontally through the through hole on the positioning rod 5224. The fixing plate 5225 is vertically arranged, the top of the fixing plate 5225 is fixedly connected to the lower surface of the connecting rod 521. The second spring 5226 is horizontally arranged, one end of the second spring 5226 is fixedly connected to the moving plate 5222, and the other end of the second spring 5226 is fixedly connected to the fixing plate 5225.

[0047] The sphere 514 can rotate into the gap between the arc surfaces of the two semi-cylinders 5221, so that the two semi-cylinders 5221 move away from each other, thereby moving the wire brush 1 523 and the wire brush 2 524 to remove rust from the top of the water tank of the sweeper, and the moving directions of the wire brush 1 523 and the wire brush 2 524 are opposite.

[0048] When the sphere 514 rotates out of the gap between the arc surfaces of the two semi-cylinders 5221, the semi-cylinders 5221 are reset due to the tension of the spring 2 5226, so that the wire brush 1 523 and the wire brush 2 524 move to remove rust from the top of the water tank of the sweeper, and the moving directions of the wire brush 1 523 and the wire brush 2 524 are opposite.

[0049] The working principle and use process of the embodiment of the present invention are as follows: Step 1: first insert the water tank of the sweeper into the inner side of the gear ring 426, and the top of the water tank of the sweeper is in close contact with the wire brush 1 523 and the wire brush 2 524;

[0050] Step 2: Drive the slide rail 511 to make the support frame 512 move horizontally to the right, and the support frame 512 drives the multiple balls 514 to pass through the gap between the arc surfaces of the two semi-cylinders 5221, so that the wire brush 1 523 and the wire brush 2 524 reciprocate to brush the top of the sweeper water tank to remove rust; at the same time, the support frame 512 will also drive the rack 515 to move horizontally to rotate the gear ring 426, thereby driving the sweeper water tank to rotate, so that the top of the sweeper water tank below the gap between the wire brush 1 523 and the wire brush 2 524 will also be brushed, so that the rust on the top of the sweeper water tank can be fully and completely brushed, thereby improving the rust removal efficiency and better meeting the rust removal and cleaning requirements before welding the top of the sweeper water tank;

[0051] Step 3: When the slide rail 511 drives the support frame 512 to move to the rightmost end, the slide rail 511 is closed, and at the same time, the telescopic device 2 411 is started to make the concave surface 1 4121 of the clamping block 1 412 close to the outer surface of the water tank of the sweeper;

[0052] Step 4: When the telescopic rod of the second telescopic device 411 is extended to the longest position, the second telescopic device 411 is closed, so that the clamping block 1 412 and the clamping block 2 421 clamp the sweeper water tank and move it to the bottom of the welding gun 32 (the sweeper water tank is located above the discharge hole 21 at this time), and the spring 1 422 is in a compressed state at this time;

[0053] Step 5: Drive the telescopic rod of the telescopic device 1 31 to extend downward, so that the welding gun 32 can weld the top of the water tank of the sweeper, and at this time, the limit plate 33 is inserted into the vibration space 429;

[0054] Step 6: After the welding work on the top of the sweeper water tank by the welding gun 32 is completed, the telescopic rod of the telescopic device 2 411 is driven to slowly shrink to the shortest position and reset. Due to the action of gravity, the sweeper water tank falls onto the conveying device 7 through the discharge hole 21, thereby realizing automatic discharge of the sweeper water tank after the welding work is completed; at this time, since the limit plate 33 is still in the vibration space 429, the spring 1 422 cannot be reset. However, when the clamping block 1 412 is just separated from the sweeper water tank, the spring 1 422 will stretch a distance, causing the folding plate 428 to hit the limit plate 33, thereby causing the clamping block 2 421 to vibrate, and then causing the sweeper water tank to vibrate, so that the sweeper water tank can fall onto the conveying device 7 through the discharge hole 21.

[0055] Step 7: Drive the telescopic device 31 to reset the welding gun 32, and the limit plate 33 leaves the vibration space 429 to reset the spring 422.

[0056] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0057] Advantage 1. When using the handheld sweeper water tank positioning welding device, the telescopic device 2 411 is driven to clamp the clamping block 1 412 and the clamping block 2 421 to clamp the sweeper water tank and position it directly below the welding gun 32. The welding gun 32 is used to weld the top of the sweeper water tank. After the welding work is completed, the telescopic rod of the telescopic device 2 411 is driven to slowly shrink to the shortest position and reset. Due to the action of gravity, the sweeper water tank falls onto the conveying device 7 through the unloading hole 21, thereby realizing automatic unloading of the sweeper water tank after the welding work is completed. This solves the technical problem that after the existing water tank positioning welding device positions the sweeper water tank and completes the welding work, the welded sweeper water tank cannot be automatically unloaded and separated from the water tank positioning welding device, thereby affecting the water tank positioning welding device to perform positioning welding on the next sweeper water tank.

[0058] Advantage 2. When using this handheld sweeper water tank positioning welding device, after the sweeper water tank welding work is completed, the telescopic rod of the driving telescopic device 2 411 is slowly retracted to the shortest position and reset. Since the limit plate 33 is still in the vibration space 429, the spring 1 422 cannot be reset. However, when the clamping block 1 412 is just separated from the sweeper water tank, the spring 1 422 will stretch a distance, causing the folding plate 428 to hit the limit plate 33, thereby causing the clamping block 2 421 to vibrate, and then causing the sweeper water tank to vibrate, so that the sweeper water tank can fall onto the conveying device 7 through the discharge hole 21, thereby improving the reliability of the device.

[0059] Advantage three: When using the handheld sweeper water tank positioning welding device, first insert the sweeper water tank into the inner side of the gear ring 426. Since the spring 1 422 is not subjected to external force at this time, the top of the sweeper water tank is tightly attached to the wire brush 1 523 and the wire brush 2 524. The driving slide rail 511 makes the support frame 512 move horizontally to the right. The support frame 512 drives multiple spheres 514 to pass through the gap between the arc surfaces of the two semi-cylinders 5221, so that the wire brush 1 523 and the wire brush 2 524 reciprocate to brush the top of the sweeper water tank to remove rust, thereby meeting the rust removal and cleaning requirements before welding the top of the sweeper water tank.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
