Positioning mechanism for welding undercarriage of high-pressure cleaning machine

Abstract

This invention belongs to the field of welding technology, specifically a positioning mechanism for welding the base frame of a high-pressure washer. It includes an adjusting base frame, assembled from side plates on both sides and a connecting plate in the middle. To accommodate welding rods of different lengths, the left and right sides of the adjusting base frame can slide along the connecting plate in the middle, adjusting the spacing between the side plates. Because the flat box limits the welding plate through the upper and lower sliding plates and the internal adsorption core, there are no obstructions hindering the welding components on the side where the welding plate and welding rod contact. Furthermore, a lower welding component is provided below, which can cooperate with the upper welding component to perform more comprehensive welding work on the base frame. This ensures that the array of welding rods can be welded to the side of the plate in one go, avoiding the need for secondary welding after welding only one side of the base frame. A poorly welded base frame is prone to loosening of the rods during rotation, leading to detachment.

Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically a positioning mechanism for welding the base frame of a high-pressure cleaner. Background Technology

[0002] High-pressure washers are mainly used for cleaning sanitary environments such as airplanes, trains, tanks, cars, stadiums, and toilets. They are a new type of cleaning machine with independent design, novel and compact structure, light weight, flexible and convenient operation, easy maintenance, stable and reliable performance, strong cleaning power, and water and energy saving.

[0003] A positioning mechanism for welding the base frame of a high-pressure washer, with publication number CN112091515A, can position and press the side plates and intermediate support plates together during the welding process of the high-pressure washer base frame, thus facilitating manual or automatic welding and ensuring that the welded product can be placed flat. However, during the clamping process of this positioning mechanism, the intermediate support plate under the base frame will significantly obstruct the welding view and the movement space of the welding rod. Therefore, after welding one side of the plate, it is necessary to flip it for secondary welding. Furthermore, the base frame that is not firmly welded is prone to loosening during rotation. Therefore, the positioning mechanism needs to be improved. Summary of the Invention

[0004] To address the problem of low welding efficiency caused by welding dead angles during the welding of the base frame of a high-pressure washer in existing technologies, the technical solution adopted in this invention is: a positioning mechanism for welding the base frame of a high-pressure washer, comprising:

[0005] The base frame is assembled from side plates on both sides and a connecting plate in the middle. In order to ensure that it can accommodate welded rods of different lengths, the left and right sides of the base frame can slide along the connecting plate in the middle to adjust the distance between the side plates.

[0006] The clamping plate components are symmetrically arranged on the left and right sides of the top of the adjusting base frame. The side of the clamping plate components is provided with a welding plate body, and the clamping plate components are used to temporarily fix the welding plate body.

[0007] The propulsion components are evenly arranged on the left and right sides of the bottom of the inner wall of the adjustment base, and the upper part of the propulsion components is provided with the lower welding components.

[0008] Support components are evenly distributed at the bottom of the inner wall of the adjustment base, and a welded rod is provided at the top of the support components;

[0009] The clamping plate component includes:

[0010] A flat box, wherein the side of the flat box is fixedly connected to the top of the outer surface of the adjusting base;

[0011] The outer surface of the push slide is slidably connected to the inner wall of the flat box, and the inner cavity of the push slide is fixedly connected to the built-in magnetic plate. When the push slide slides out from the inside of the flat box, it can abut against the upper and lower sides of the welding plate. The built-in magnetic plate inside the plate generates a magnetic attraction effect on the welding plate, thereby stabilizing the welding plate.

[0012] The control rollers are symmetrically arranged on both sides of the inner wall of the flat box, and the outer surface of the control rollers is meshed with the outer surface of the propulsion slide. The control rollers are controlled by a motor inside the flat box to rotate, and are used to control the horizontal sliding motion of the propulsion slide.

[0013] The lower welding component includes:

[0014] An annular shell, wherein the inner cavity of the annular shell is uniformly provided with through grooves, and the inner wall of the annular shell is uniformly provided with guide sleeves;

[0015] The welding rod sleeve, located inside the guide sleeve, is used to fix the welding rod at the lower position of the welding rod. The lower welding component performs welding work on the lower part of the welding rod body through the sleeved welding rod.

[0016] Furthermore, the lower welding component also includes:

[0017] The outer surface of the pressure plate is fixedly connected to the outer surface of the annular shell. The air jets of the pressure plate are evenly provided with insertion tubes, which extend into the interior of the annular shell. After the pressure plate pressurizes the interior of the annular shell, the welding rod sleeve can be pushed towards the welding rod body.

[0018] The magnetic block has its outer surface fixedly connected to the inner wall of the annular shell. The magnetic block can generate a magnetic attraction when the welding equipment above comes into contact with the two sides of the annular shell, thereby improving the stability of the annular shell.

[0019] The side-push component is used to propel the guide sleeve toward the direction of the welding area.

[0020] Furthermore, the welding rod sleeve includes:

[0021] The welding rod sliding sleeve has heat dissipation holes evenly opened at the top of the inner cavity of the welding rod sliding sleeve, and symmetrically arranged mating protrusions at the bottom of the outer surface of the welding rod sliding sleeve. The outer surface of the welding rod sliding sleeve is slidably connected to the groove position of the inner wall of the guide sliding sleeve through the mating protrusions. A through hole for wire threading is opened in the middle of the welding rod sliding sleeve to ensure that the installed welding rod end can be powered normally.

[0022] A compression spring is provided, with one end fixedly connected to the outer surface of the mating protrusion and the other end pressing against the inner wall of the sliding sleeve. When the sliding sleeve slides outward under the pressure generated by the outer pressure plate, it can drive the compression springs on both sides to perform the pressing action. After the work is completed, the outer pressure plate stops working, the compression spring rebounds, and drives the welding rod sliding sleeve to reset.

[0023] Furthermore, the side-pushing component includes:

[0024] A control air cylinder, wherein the outer surface of the control air cylinder is fixedly connected to the side of the inner wall of the annular shell away from the guide sleeve;

[0025] A guide rod, one end of which is fixedly connected to the axis of the outer surface of the control cylinder, and the other end of which is fixedly connected to the inner wall of the annular shell;

[0026] A connecting slider is provided, wherein the outer surface of the connecting slider is fixedly connected to the outer surface of the guide sleeve, and the inner wall of the connecting slider is slidably connected to the inner wall of the guide rod.

[0027] A rubber sleeve is provided, with one end of the rubber sleeve fixedly connected to the outer surface of the connecting slider and the other end of the rubber sleeve fixedly connected to the outer surface of the control air cylinder. After the control air cylinder pressurizes the inside of the rubber sleeve, it will push the connecting slider to slide away from the control air cylinder. At this time, the welding rod will also move towards the contact area between the welding plate and the welding rod.

[0028] Furthermore, the propulsion component includes:

[0029] A vertical guide rail, the outer surface of which is fixedly connected to the inner wall of the adjusting base frame;

[0030] A pressure push box, wherein the outer surface of the pressure push box is fixedly connected to the bottom of the inner wall of the vertical guide rail, and a compression connecting rod is fixedly connected to the top of the pressure push box;

[0031] The load-bearing slide plate has one side of its outer surface slidably connected to the inner wall of the vertical guide rail, and the other side of its outer surface is fixedly connected to an arc-shaped slide rail. The inner wall of the arc-shaped slide rail is evenly provided with active rollers, which are slidably connected to the outer surface of the annular shell. The outer surfaces of the active rollers and the outer surfaces of the pressure plate are pressed against each other. The active rollers can drive the lower welding component to rotate around the inner wall of the arc-shaped slide rail, with its axis being the same as the axis of the welding rod. This allows the lower welding rod to sweep across the area to be welded, enabling more comprehensive welding work. To ensure the lower welding component does not detach from the arc-shaped slide rail, its deflection range is limited, so it can only cooperate with the upper welding components for welding work.

[0032] Furthermore, the clamping plate component also includes:

[0033] The adsorption core has its outer surface fixedly connected to the inner wall of the flat box, and both its front and rear ends extend to the outside of the flat box through exhaust ports.

[0034] A docking suction cup is provided, with one end of the docking suction cup fixedly connected to the air inlet of the adsorption core, and the other end of the docking suction cup being pressed against the side of the welding plate.

[0035] Furthermore, the support component includes:

[0036] A vertical sleeve, wherein a vertical sliding rod is slidably connected to the inner wall of the vertical sleeve;

[0037] A horizontal connecting shaft, the side of which is inserted into the top of a vertical slide rod;

[0038] A rotary clamping plate, the bottom end of which is rotatably connected to the outer surface of a horizontal connecting shaft via a guide groove. A return spring inside the horizontal connecting shaft causes the rotary clamping plate to deflect towards the outer surface of the welding rod, thereby clamping the outer surface of the welding rod through the rotary clamping plates on both sides. Figure 1 As shown;

[0039] An embedded roller shaft is provided, the outer surface of which is rotatably connected to the inner cavity of the rotary clamping plate, and the outer surface of the embedded roller shaft is pressed against the outer surface of the welded rod.

[0040] Furthermore, the support component also includes:

[0041] A protective cover, the outer surface of which is fixedly connected to the outer surface of the rotary clamp;

[0042] The torsion roller shaft has its outer surface rolledly connected to the outer surface of the embedded roller shaft. Both ends of the torsion roller shaft are rotatably connected to the inner wall of the protective cover via a power motor. The torsion motor inside the protective cover drives the torsion roller shaft to rotate, and through the transmission action, the welding rod rotates.

[0043] The beneficial effects of this invention are as follows:

[0044] 1. This device can limit the welding plates and welding rods required for the base plate, ensuring their stability during welding. Since the flat box limits the welding plates through the upper and lower sliding plates and the internal adsorption core, there will be no obstructions to the welding components on the side where the welding plates and welding rods contact. Furthermore, a lower welding component is provided below, which can cooperate with the upper welding component to perform a more comprehensive welding operation on the base frame. This ensures that the welding rods of the array can be welded to the side of the plate in one go, avoiding the need for a second welding after welding one side of the base frame. If the base frame is not firmly welded, the rods are prone to loosening when the frame is turned, leading to the problem of the rods detaching from the weld.

[0045] 2. This device can uniformly weld the array of welding rods onto the outer surface of the welding plate in a single process, thereby quickly achieving the welding process of the base plate and greatly improving welding efficiency. Since the welding rods are uniformly arranged, they can be ensured to be parallel in the same plane during the welding process, and adjacent welding rods can be used for comparison. Compared with the method of welding individual welding rods, this uniform welding method can quickly detect welding rods that are misaligned, so as to correct them in time.

[0046] 3. The lower welding component can move towards the welding point of the base frame under the control of the propulsion component. Then, through the internal propulsion structure, the welding rod sleeved at the top of the welding rod is further pushed to the contact point to achieve welding. After the upper welding work is completed, the lower welding component can repeatedly deflect around the outer surface of the welding rod under the control of the arc-shaped slide rail, so as to perform repair welding on the swept area through the welding head, and then completely weld the welding rod and the welding plate, thus solving the problem that it is difficult to weld adjacent seams of the welding rod by general welding equipment.

[0047] 4. Before welding, the welding rod is in contact with the side of the welding plate. At this time, the inner roller shaft is driven by the torsion roller shaft to rotate. The inner roller shaft causes the welding rod to rotate. The state of the welding rod is then observed. If the welding rod wobbles relative to the welding plate, the end of the welding rod is not perpendicular to the outer surface of the welding plate. The end of the welding rod needs to be treated and adjusted to avoid the problem of the welding rod being misaligned with the two side plates of the base frame after welding.

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0059] Example 1, please refer to Figures 1-4 The present invention provides a technical solution: a positioning mechanism for welding the base frame of a high-pressure cleaner, comprising:

[0060] Adjust the base frame 1, which is assembled from the side plates on both sides and the connecting plate in the middle. In order to ensure that it can accommodate welding rods 7 of different lengths, the left and right sides of the base frame 1 can slide along the connecting plate in the middle to adjust the spacing between the side plates.

[0061] The clamping plate component 3 is symmetrically arranged on the left and right sides of the top of the adjusting base frame 1. The side of the clamping plate component 3 is provided with a welding plate 6. The clamping plate component 3 is used to temporarily fix the welding plate 6.

[0062] The propulsion component 4 is evenly arranged on the left and right sides of the bottom of the inner wall of the adjustment base frame 1, and the upper part of the propulsion component 4 is provided with the lower welding component 5.

[0063] Support components 2 are evenly arranged at the bottom of the inner wall of the adjusting base frame 1, and a welded rod 7 is provided at the top of the support components 2;

[0064] Clamping plate component 3 includes:

[0065] The side of the flat box 31 is fixedly connected to the top of the outer surface of the adjusting base frame 1;

[0066] The outer surface of the push slide 32 is slidably connected to the inner wall of the flat box 31, and the inner cavity of the push slide 32 is fixedly connected to the built-in magnetic plate 33. When the push slide 32 slides out from the inside of the flat box 31, it can abut against the upper and lower sides of the welding plate 6. The built-in magnetic plate 33 inside generates a magnetic attraction effect on the welding plate 6, thereby stabilizing the welding plate 6.

[0067] The control roller 34 is symmetrically arranged on both sides of the inner wall of the plane box 31, and the outer surface of the control roller 34 is meshed with the outer surface of the push slide 32. The control roller 34 is controlled to rotate by a motor inside the plane box 31, which is used to control the push slide 32 to perform horizontal sliding motion.

[0068] The lower welding component 5 includes:

[0069] The annular shell 51 has through grooves 52 evenly distributed in its inner cavity, and guide sleeves 53 are evenly distributed on its inner wall.

[0070] The welding rod sleeve 56 is located inside the guide sleeve 53 and is used to fix the welding rod at the lower position. The lower welding component 5 performs welding work on the lower part of the welding rod body 7 through the sleeved welding rod.

[0071] According to the required welding rod 7 length, the plates on both sides of the adjusting base 1 are slid relative to each other. Then, the welding plates 6 on both sides are attached to the sides of the flat box 31. Then, the control roller 34 inside the flat box 31 is rotated to push out the push slide 32 and abut against the upper and lower sides of the welding plate 6, but not beyond the welding plate 6. The adsorption core 35 inside the flat box 31 will adsorb the outer surface of the welding plate 6 through the docking suction cup 36, thereby fixing the welding plate 6 to the outer surface of the flat box 31. Then, the welding rod 7 is placed on the support component 2, the height of the support component 2 is adjusted to stabilize the position of the welding rod 7 and the welding plate 6. After the position of the welding rod 7 is fixed, the distance between the two sides of the adjusting base 1 is changed again to press the welding plate 6 and the welding rod 7 together, thus completing the preparation work.

[0072] During welding, the upper welding equipment welds the contact area between the welding plate 6 and the welding rod 7. Simultaneously, the lower welding component 5 drives the installed welding rod to perform welding on the lower part of the contact area between the welding plate 6 and the welding rod 7. The specific operation is as follows: the pushing component 4 pushes the lower welding component 5 upward, and the annular shell 51 is fitted onto the outside of the welding rod 7, with its axis overlapping the axis of the welding rod 7. Then, the pushing component 4 stops moving, and the outer plate 54 pressurizes the annular shell 5. The internal pressure of 1 causes the welding rod sleeve 56 inside the guide sleeve 53 to move towards the outer surface of the welding rod body 7 under the action of air pressure. At the same time, the control air cylinder 571 also pushes the connecting slider 574 to slide along the outer surface of the guide rod 572 by pressurizing the rubber sleeve 573. This causes all the welding rod sleeves 561 to slide towards the contact area between the welding rod body 7 and the welding plate body 6. At this time, the welding rod at the end of the welding rod sleeve 561 performs welding work on the contact area between the welding plate body 6 and the welding rod 7.

[0073] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the lower welding component 5 further includes:

[0074] The outer surface of the pressure plate 54 is fixedly connected to the outer surface of the annular shell 51. The air nozzles of the pressure plate 54 are evenly provided with insertion tubes 55, and the insertion tubes 55 extend into the interior of the annular shell 51. After the pressure plate 54 pressurizes the interior of the annular shell 51, the welding rod sleeve 56 can be pushed towards the welding rod body 7.

[0075] The magnetic block 58 has its outer surface fixedly connected to the inner wall of the annular shell 51. The magnetic block 58 can generate a magnetic attraction when the relevant welding equipment comes into contact with both sides of the annular shell 51, thereby improving the stability of the annular shell 51.

[0076] The side-pushing component 57 is used to propel the guide sleeve 53 toward the direction of the welding part.

[0077] Welding rod sleeve 56 includes:

[0078] The welding rod slide sleeve 561 has heat dissipation holes 562 evenly opened at the top of the inner cavity of the welding rod slide sleeve 561, and symmetrical mating protrusions 563 are arranged at the bottom of the outer surface of the welding rod slide sleeve 561. The outer surface of the welding rod slide sleeve 561 is slidably connected to the groove position of the inner wall of the guide slide sleeve 53 through the mating protrusions 563. The middle part of the welding rod slide sleeve 561 has a through hole for threading wire to ensure that the welding rod end can be powered normally.

[0079] Compression spring 564, one end of compression spring 564 is fixedly connected to the outer surface of mating protrusion 563, and the other end of compression spring 564 is pressed against the inner wall of the inner wall of the sliding sleeve. When the guide sliding sleeve 53 slides outward under the pressure generated by the pressure plate 54, it can drive the compression springs 564 on both sides to perform the pressing action. After the work is completed, the pressure plate 54 stops working, the compression spring 564 rebounds, and drives the guide sliding sleeve 53 to reset.

[0080] Side thrust component 57 includes:

[0081] The control air cylinder 571 is fixedly connected to the inner wall of the annular shell 51 on the side away from the guide sleeve 53.

[0082] Guide rod 572, one end of which is fixedly connected to the axis of the outer surface of the control air cylinder 571, and the other end of which is fixedly connected to the inner wall of the annular shell 51;

[0083] Connecting slider 574, the outer surface of connecting slider 574 is fixedly connected to the outer surface of guide sleeve 53, and the inner wall of connecting slider 574 is slidably connected to the inner wall of guide rod 572;

[0084] The rubber sleeve 573 has one end fixedly connected to the outer surface of the connecting slider 574, and the other end fixedly connected to the outer surface of the control air cylinder 571. After the control air cylinder 571 pressurizes the inside of the rubber sleeve 573, it will push the connecting slider 574 to slide away from the control air cylinder 571. At this time, the welding rod will also move towards the contact area between the welding plate 6 and the welding rod 7.

[0085] Propulsion component 4 includes:

[0086] Vertical guide rail 41, the outer surface of vertical guide rail 41 is fixedly connected to the inner wall of adjustment base frame 1;

[0087] The outer surface of the pressure push box 43 is fixedly connected to the bottom of the inner wall of the vertical guide rail 41, and the top of the pressure push box 43 is fixedly connected to the compression connecting rod 44.

[0088] The load-bearing slide plate 42 has one side of its outer surface slidably connected to the inner wall of the vertical guide rail 41, and the other side of its outer surface is fixedly connected to an arc-shaped slide rail 45. The inner wall of the arc-shaped slide rail 45 is evenly provided with active rollers 46. The inner wall of the arc-shaped slide rail 45 is slidably connected to the outer surface of the annular shell 51, and the outer surface of the active rollers 46 is pressed against the outer surface of the pressure plate 54. The active rollers 46 can drive the lower welding component 5 to rotate around the inner wall of the arc-shaped slide rail 45. Its axis is the same as the axis of the welding rod 7, that is, it rotates around the welding rod 7, so that the lower welding rod can sweep over the part to be welded and perform a more comprehensive welding work. In order to ensure that the lower welding component 5 does not detach from the arc-shaped slide rail 45, the deflection range of the lower welding component 5 is limited, so it can only cooperate with the relevant welding components above to perform welding work.

[0089] Clamping plate component 3 also includes:

[0090] The adsorption core 35 has its outer surface fixedly connected to the inner wall of the flat box 31, and both the front and rear ends of the adsorption core 35 extend to the outside of the flat box 31 through the exhaust port.

[0091] The suction cup 36 is connected to the air inlet of the adsorption core 35 at one end, and the other end of the suction cup 36 is pressed against the side of the welding plate 6.

[0092] Support component 2 includes:

[0093] Vertical sleeve 21, with a vertical slide rod 22 slidably connected to the inner wall of vertical sleeve 21;

[0094] The horizontal connecting shaft 23 is inserted into the top of the vertical slide rod 22.

[0095] The bottom end of the rotary clamping plate 24 is rotatably connected to the outer surface of the horizontal connecting shaft 23 via a guide groove. The return spring inside the horizontal connecting shaft 23 causes the rotary clamping plate 24 to deflect towards the outer surface of the welding rod 7, thereby clamping the outer surface of the welding rod 7 through the rotary clamping plates 24 on both sides. Figure 1 As shown;

[0096] The inner roller shaft 26 has its outer surface rotatably connected to the inner cavity of the rotary clamp 24, and its outer surface is pressed against the outer surface of the welded rod 7.

[0097] Support component 2 also includes:

[0098] The outer surface of the protective cover 25 is fixedly connected to the outer surface of the rotary clamp 24.

[0099] The outer surface of the torsion roller shaft 27 is rolledly connected to the outer surface of the embedded roller shaft 26. Both ends of the torsion roller shaft 27 are rotatably connected to the inner wall of the protective cover 25 through a power motor. The torsion motor inside the protective cover 25 drives the torsion roller shaft 27 to rotate, and through the transmission action, the welding rod 7 rotates.

[0100] After the upper welding equipment finishes welding the contact area, the lower arc-shaped slide rail 45 will drive the lower welding component 5 to rotate along the inner wall of the arc-shaped slide rail 45 through the rolling friction of the internal active roller 46. At this time, the welding rod will deflect relative to the welding rod body 7, thereby performing welding work on the contact area during the rotation. When the lower welding component 5 deflects to the maximum angle relative to the arc-shaped slide rail 45, the active roller 46 drives the lower welding component 5 to deflect in the opposite direction to the maximum angle, thereby completely welding the contact area below the welding rod body 7 and achieving a comprehensive welding effect.

[0101] After welding is completed, the pressure outer plate 54 stops working. At this time, the welding rod sleeve 561 retracts into the annular shell 51 under the elastic force of its own compression spring 564. The rubber sleeve 573 also pulls the guide sleeve 53 away from the adjustment base frame 1 through the connecting slider 574. Then, the pressure push box 43 pulls down the load-bearing slide plate 42 by decompressing the compression connecting rod 44, and retracts the lower welding part 5. The flat box 31 also retracts the upper and lower push slide plates 32 and removes the welded base plate.

[0102] After the welding rod 7 is placed at the top of the support component 2, the rotating clamps 24 on both sides clamp the outer surface of the welding rod 7 under the rebound action of the spring inside the horizontal connecting shaft 23. Then, the vertical sleeve 21 adjusts the actual height of the vertical slide bar 22, so that the vertical slide bar 22 slides up and down to ensure that the welding rod 7 can be aligned with the reserved position of the welding plate 6 before welding. Since the welding rod 7 is in contact with the side of the welding plate 6, the torsion roller shaft 27 drives the embedded roller shaft 26 to rotate. The embedded roller shaft 26 makes the welding rod 7 rotate, and then observes the state of the welding rod 7. If the welding rod 7 wobbles relative to the welding plate 6, the end of the welding rod 7 is not perpendicular to the outer surface of the welding plate 6. It is necessary to process and adjust the end of the welding rod 7 to avoid the problem of the rod and the two side plates being misaligned after welding.

[0103] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
