Description

Technical Field

[0001] The present invention belongs to the technical field of shell welding devices, and in particular relates to a shell welding device for water pump production and a method of using the same. Background Art

[0002] The water pump casing welding device is a device used for processing and manufacturing water pump casings. Its main function is to connect the different components of the water pump casing together through welding process to ensure the overall structural strength and sealing of the casing. This device usually includes welding equipment, positioning mechanism, cooling system, etc., which are used to optimize the welding process and improve the welding quality.

[0003] The water pump casing is usually composed of: base plate, fixing mechanism, moving device, welding gun, welding unit, cooling system, positioning mechanism and auxiliary components. The water pump casing welding device achieves efficient and high-quality welding effects through the coordinated work of these components.

[0004] With the development, manual welding methods are gradually replaced by automation, and the scope of use of welding robots is gradually expanding. Although most welding robots are fixedly installed, if they need to move, they still need to rely on a motion system. The current free motion system is not well developed and mainly relies on guide rails for movement.

[0005] At present, when a welding robot welds the casing of a water pump, the welding robot needs to move along the track. During the movement, it may collide with the fixed frame or workpiece due to programming and other problems. The existing welding robots do not have corresponding protection mechanisms. This collision can easily cause damage to the welding robot and even tilt the base, which not only reduces the service life of the welding robot, but also causes the center of gravity of the welding robot to shift. In severe cases, it may even cause the welding robot to fall over or be damaged, which is not conducive to long-term use.

[0006] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0007] The purpose of the present invention is to provide a shell welding device for water pump production and a method of using the same, which can solve the problem that when a welding robot is performing track displacement, there is no corresponding protection mechanism, which can easily cause damage to the welding robot or even overturn it in the event of a collision.

[0008] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0013] A pressure support mechanism is fixedly installed on the welding robot base.

[0014] In one or more embodiments of the present invention, support and pull shaft seats are fixedly installed on both sides of the welding robot base, which facilitates the rotation of the support and pull connecting plate, provides corresponding assistance for the connection between the support and pull connecting plate and the welding robot base, reduces the probability of the support and pull connecting plate detaching from the welding robot base, improves the connectivity between the welding robot base and the power device, and makes the rotation of the support and pull connecting plate more stable;

[0015] The support and pull shaft seat is arranged through the support and pull connecting plate, which facilitates the rotation of the support and pull connecting plate, enables the support and pull connecting plate to be better connected to the welding robot base, and enables the support and pull connecting plate to rotate better;

[0016] A supporting and pulling first bearing is installed between the supporting and pulling shaft seat and the supporting and pulling connecting plate, which reduces the friction between the supporting and pulling connecting plate and the supporting and pulling shaft seat, improves the service life of the supporting and pulling connecting plate and the supporting and pulling shaft seat, reduces the probability of damage to the supporting and pulling connecting plate and the supporting and pulling shaft seat, and enables the supporting and pulling connecting plate to better fix the position of the welding robot base.

[0017] In one or more embodiments of the present invention, a displacement groove matching the support and pull guide rod is bored in the support and pull connecting plate, which facilitates the displacement of the support and pull guide rod, enables the support and pull guide rod to guide the rotation of the support and pull connecting plate, and enables the support and pull guide rod to more conveniently compress the support and pull sliding rod, so that the support and pull guide rod can pull the support and pull connecting plate together with the support and pull shaft seat;

[0018] The outer sleeve of the support and pull guide rod is provided with a support and pull second bearing, which reduces the friction between the support and pull guide rod and the support and pull connecting plate, improves the service life of the support and pull guide rod and the support and pull connecting plate, improves the use effect of the support and pull guide rod and the support and pull connecting plate, and makes the support and pull guide rod slide smoothly in the support and pull connecting plate;

[0019] The support and pull positioning rod is fixedly installed with the power device, which improves the balance of the support and pull positioning rod, reduces the probability of the support and pull positioning rod tilting, improves the stability of the support and pull positioning rod, enables the support and pull positioning rod to better fix the support and pull guide rod, and enables the support and pull guide rod to better guide the support and pull connecting plate.

[0020] In one or more embodiments of the present invention, the pulling buffer mechanism includes a pulling buffer support frame, and a pair of pulling buffer support frames can improve the stability of the welding robot base and simultaneously reduce the probability of tilting of the welding robot base;

[0021] A pulling buffer cushion is fixedly installed on the pulling buffer support frame, which improves the friction between the welding robot base and the pulling buffer support frame, reduces the probability of the welding robot base shaking, and further improves the stability of the welding robot base;

[0022] A pulling buffer electromagnet is provided on the upper side of the pulling buffer support frame, which can attract the pulling buffer support frame, thereby reducing the tilt amplitude of the welding robot base, reducing the probability of the welding robot base tilting, and preventing the welding robot mounted on the welding robot base from shaking after a slight impact;

[0023] A receiving groove matching the pulling buffer electromagnet is bored in the base of the welding robot, which facilitates the installation of the pulling buffer electromagnet and provides a corresponding installation position for the pulling buffer electromagnet, thereby reducing the probability of the pulling buffer electromagnet shaking and the probability of the pulling buffer electromagnet detaching.

[0024] In one or more embodiments of the present invention, a pulling buffer filter is provided on the lower side of the pulling buffer electromagnet. When the pulling buffer electromagnet attracts the pulling buffer support frame, it continuously attracts iron-containing debris, and the pulling buffer filter can block the debris.

[0025] The welding robot base is provided with a blocking groove that matches the pulling buffer filter. The pulling buffer electromagnet can not only attract the pulling buffer filter, making the pulling buffer filter more stable and reducing the probability of the pulling buffer filter detaching, but also the user can remove the pulling buffer filter to clean the debris. The blocking groove facilitates the installation of the pulling buffer filter.

[0026] A pulling buffer pressure chamber is rotatably installed on one side of the pulling buffer support frame, which facilitates the installation of the pulling buffer pressure plate and provides corresponding space for the installation of the pulling buffer pressure plate. At the same time, it facilitates the accommodation of hydraulic oil and provides corresponding space for the accommodation of hydraulic oil.

[0027] In one or more embodiments of the present invention, a pulling buffer pressure plate is slidably installed in the pulling buffer pressure chamber, which can slide in the pulling buffer pressure chamber to squeeze the hydraulic oil in the pulling buffer pressure chamber. By sliding in the hydraulic oil, the displacement speed of the pulling buffer pressure plate can be effectively slowed down;

[0028] A pulling buffer connecting rod is fixedly installed on one side of the pulling buffer pressure plate, which is connected to the supporting pulling connecting plate. The rotation of the supporting pulling connecting plate can pull the pulling buffer connecting rod, so that the pulling buffer pressure plate can be displaced and the hydraulic oil in the pulling buffer pressure chamber is squeezed. The pulling buffer connecting rod runs through the pulling buffer pressure chamber.

[0029] In one or more embodiments of the present invention, a pulling buffer sealing ring is installed between the pulling buffer connecting rod and the pulling buffer pressure chamber, thereby improving the sealing between the pulling buffer connecting rod and the pulling buffer pressure chamber and reducing the possibility of hydraulic oil leakage in the pulling buffer pressure chamber;

[0030] The pull-and-buffer connecting rod is rotatably mounted on the support-and-pull connecting plate, so that the rotation of the support-and-pull connecting plate will not cause the support-and-pull connecting plate to separate from the pull-and-buffer connecting rod, thereby reducing the probability of the support-and-pull connecting plate separating from the pull-and-buffer connecting rod, and enabling the rotation of the support-and-pull connecting plate to better drive the displacement of the pull-and-buffer connecting rod;

[0031] The pulling buffer pressure plate is provided with a plurality of flow grooves, which facilitate the circulation of the hydraulic oil so that the hydraulic oil can slow down the displacement speed of the pulling buffer pressure plate without causing the pulling buffer pressure plate to stop displacement.

[0032] In one or more embodiments of the present invention, the pressure support mechanism includes a pressure support accommodating chamber, which facilitates the sliding of the pressure support positioning rod, provides corresponding guidance for the sliding of the pressure support positioning rod, and can also accommodate hydraulic oil;

[0033] A pressure support positioning rod is slidably installed in the pressure support accommodation chamber, which can support the welding robot base, so that after the welding robot base rotates, it can squeeze the pressure support positioning rod, so that the pressure support positioning rod can slow down the rotation speed of the welding robot base;

[0034] A plurality of pressure support springs are installed between the pressure support positioning rod and the pressure support accommodating chamber, which can squeeze the pressure support positioning rod and provide the pressure support positioning rod with a force to always slide upward, so that the pressure support positioning rod can better support the welding robot base. At the same time, the pressure support positioning rod can rise after being free of force, providing better buffering for the welding robot base.

[0035] The pressure support positioning rod is provided with a plurality of pressure grooves, which facilitate the displacement of the pressure support positioning rod and enable the hydraulic oil to slow down the sliding speed of the pressure support positioning rod without causing stagnant displacement of the pressure support positioning rod.

[0036] In one or more embodiments of the present invention, a plurality of pairs of pressure support guide rods are fixedly mounted on the welding robot base, which facilitates the sliding of the pressure support positioning block and provides corresponding guidance for the sliding of the pressure support positioning block, thereby reducing the probability of the pressure support positioning block being detached;

[0037] A pressure support positioning block is slidably mounted on the pressure support guide rod to support the pressure support spring piece, so that the deformation process of the pressure support spring piece can drive the sliding of the pressure support positioning block;

[0038] A pressure compression spring is installed between the pressure support positioning block and the pressure support guide rod, which can be squeezed by the pressure support positioning block to buffer the pressure support positioning block and slow down the sliding speed of the pressure support positioning block. A pressure support spring is installed between a pair of pressure support positioning blocks to support the welding robot base and help balance the welding robot base.

[0039] A method for using a shell welding device for water pump production includes the following steps:

[0040] S1. When the power unit slides on the guide rail, once the welding robot is hit, the welding robot base will tilt along the direction of the track;

[0041] S2. During the tilting process of the welding robot base, the support and pull connecting plate on the side of the force will be pulled, and pressure will be applied to the support and pull connecting plate on the other side. At this time, the support and pull connecting plate on the side of the force will be guided by the support and pull guide rod to slide and squeeze the support and pull sliding rod, so that the support and pull connecting plate on the side of the force is buffered and pulled, thereby reducing the tilting amplitude of the welding robot base;

[0042] S3. The support and pulling connecting plate on the other side will be supported by the support and pulling guide rod, so that the tilt of the welding robot base is supported. At the same time, the support and pulling connecting plate on the force-bearing side will pull the pulling buffer connecting rod, so that the pulling buffer pressure plate slides in the pulling buffer pressure chamber and squeezes the hydraulic oil in the pulling buffer pressure chamber, slowing down the sliding displacement of the pulling buffer pressure plate and reducing the tilt and rotation speed of the welding robot base.

[0043] S4. At the same time, when the power device slides on the guide rail, the pulling buffer electromagnet will always attract the pulling buffer support frame. When the welding robot is slightly bumped, the welding robot base is fixed by the pulling buffer electromagnet, so that the welding robot base will not tilt.

[0044] S5. When the welding robot base rotates after tilting, pressure is applied to the pressure support positioning rod and the pressure support spring. The compression of the pressure support spring and the hydraulic oil in the pressure support containing chamber slow down the descending speed of the welding robot base. At the same time, the pressure support spring and the pressure compression spring further cushion the welding robot base, and the pulling buffer pad is used to protect the welding robot base.

[0045] Compared with the prior art, the shell welding device for water pump production and the method of use thereof of the present invention reduce the damage to the welding robot when a collision occurs during track displacement through the setting of corresponding mechanisms, and reduce the probability of the base tilting. This not only improves the service life of the welding robot, but also reduces the probability of the welding robot's center of gravity shifting, thereby reducing the probability of the welding robot tipping over or being damaged, and is more conducive to long-term use.

DETAILED DESCRIPTION

[0060] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative efforts should fall within the scope of protection of the present invention.

[0061] like Figures 1 to 11 As shown, a shell welding device for water pump production in one embodiment of the present invention includes: a welding robot base 1, a pressure support mechanism 4, a pair of pulling and buffering mechanisms 3 and a pair of supporting pulling mechanisms 2.

[0062] like Figures 1 to 5 As shown, a power device 101 is provided on the lower side of the welding robot base 1, and a guide rail 102 is slidably installed on the lower side of the power device 101. A pair of supporting pulling mechanisms 2 are installed between the welding robot base 1 and the power device 101. The supporting pulling mechanism 2 includes a supporting pulling connecting plate 201. After being hit, the supporting pulling connecting plate 201 on the force-bearing side can rotate, and the supporting pulling connecting plate 201 on the other side can support the welding robot base 1, so that the welding robot base 1 rotates instead of sliding, which facilitates the buffering of the welding robot base 1.

[0063] Among them, a support and pull guide rod 202 is provided in the support and pull connecting plate 201, which can squeeze the support and pull sliding rod 205 and guide the rotation of the support and pull connecting plate 201. Support and pull positioning rods 203 are fixedly installed on both sides of the support and pull guide rod 202, which improves the balance of the support and pull guide rod 202 and reduces the chance of the support and pull guide rod 202 detaching.

[0064] In addition, several support and pull accommodating chambers 204 are fixedly installed in the support and pull connecting plate 201, which facilitates the sliding of the support and pull sliding rod 205 and provides corresponding guidance and space for the sliding of the support and pull sliding rod 205. The support and pull sliding rod 205 is slidably installed in the support and pull accommodating chamber 204, which can squeeze the support and pull pressure spring 206. A support and pull pressure spring 206 is installed between the support and pull sliding rod 205 and the support and pull accommodating chamber 204.

[0065] like Figures 1 to 8As shown, support and pulling shaft seats 207 are fixedly installed on both sides of the welding robot base 1, which facilitates the rotation of the support and pulling connecting plate 201, provides corresponding assistance for the connection between the support and pulling connecting plate 201 and the welding robot base 1, reduces the probability of the support and pulling connecting plate 201 being separated from the welding robot base 1, improves the connectivity between the welding robot base 1 and the power device 101, and makes the rotation of the support and pulling connecting plate 201 more stable.

[0066] Among them, the support and pull shaft seat 207 is set through the support and pull connecting plate 201, which facilitates the rotation of the support and pull connecting plate 201, enables the support and pull connecting plate 201 to be better connected to the welding robot base 1, and enables the support and pull connecting plate 201 to rotate better.

[0067] In addition, a supporting and pulling first bearing 208 is installed between the supporting and pulling shaft seat 207 and the supporting and pulling connecting plate 201, which reduces the friction between the supporting and pulling connecting plate 201 and the supporting and pulling shaft seat 207, improves the service life of the supporting and pulling connecting plate 201 and the supporting and pulling shaft seat 207, reduces the probability of damage to the supporting and pulling connecting plate 201 and the supporting and pulling shaft seat 207, and enables the supporting and pulling connecting plate 201 to better fix the position of the welding robot base 1.

[0068] like Figures 1 to 8 As shown, a displacement groove matching the support and pull guide rod 202 is bored in the support and pull connecting plate 201, which facilitates the displacement of the support and pull guide rod 202, so that the support and pull guide rod 202 can guide the rotation of the support and pull connecting plate 201, and make it more convenient for the support and pull guide rod 202 to compress the support and pull sliding rod 205, so that the support and pull guide rod 202 can pull the support and pull connecting plate 201 together with the support and pull shaft seat 207.

[0069] In addition, the outer sleeve of the support and pull guide rod 202 is provided with a support and pull second bearing 209, which reduces the friction between the support and pull guide rod 202 and the support and pull connecting plate 201, improves the service life of the support and pull guide rod 202 and the support and pull connecting plate 201, improves the use effect of the support and pull guide rod 202 and the support and pull connecting plate 201, and makes the support and pull guide rod 202 slide smoothly in the support and pull connecting plate 201.

[0070] In addition, the support and pull positioning rod 203 is fixedly installed with the power device 101, which improves the balance of the support and pull positioning rod 203, reduces the chance of the support and pull positioning rod 203 tilting, improves the stability of the support and pull positioning rod 203, enables the support and pull positioning rod 203 to better fix the support and pull guide rod 202, and enables the support and pull guide rod 202 to better guide the support and pull connecting plate 201.

[0071] like Figures 1 to 5 As shown, a pair of pulling buffer mechanisms 3 are fixedly installed on the power device 101. The pulling buffer mechanisms 3 include a pulling buffer support frame 301. The pair of pulling buffer support frames 301 can improve the stability of the welding robot base 1 and simultaneously reduce the probability of tilting of the welding robot base 1.

[0072] Among them, a pulling buffer pad 302 is fixedly installed on the pulling buffer support frame 301, which improves the friction between the welding robot base 1 and the pulling buffer support frame 301, reduces the probability of the welding robot base 1 shaking, and further improves the stability of the welding robot base 1.

[0073] In addition, a pulling buffer electromagnet 303 is provided on the upper side of the pulling buffer support frame 301, which can attract the pulling buffer support frame 301, reduce the tilt amplitude of the welding robot base 1, reduce the probability of the welding robot base 1 tilting, and prevent the welding robot installed on the welding robot base 1 from shaking after a slight impact.

[0074] In addition, a receiving groove matching the pulling buffer electromagnet 303 is dug in the welding robot base 1, which facilitates the installation of the pulling buffer electromagnet 303 and provides a corresponding installation position for the pulling buffer electromagnet 303, thereby reducing the probability of the pulling buffer electromagnet 303 shaking and the probability of the pulling buffer electromagnet 303 detaching.

[0075] like Figures 1 to 7 As shown, a pulling buffer filter 304 is provided on the lower side of the pulling buffer electromagnet 303. When the pulling buffer electromagnet 303 attracts the pulling buffer support frame 301, it will continuously attract iron-containing debris, and the pulling buffer filter 304 can block these debris.

[0076] In addition, a blocking groove matching the pulling buffer filter 304 is dug on the welding robot base 1. The pulling buffer electromagnet 303 can not only attract the pulling buffer filter 304, making the pulling buffer filter 304 more stable and reducing the chance of the pulling buffer filter 304 detaching, but the user can clean up the debris by disassembling the pulling buffer filter 304. The blocking groove facilitates the installation of the pulling buffer filter 304.

[0077] Among them, a pulling buffer pressure chamber 305 is rotatably installed on one side of the pulling buffer support frame 301, which facilitates the installation of the pulling buffer pressure plate 306 and provides corresponding space for the installation of the pulling buffer pressure plate 306. At the same time, it facilitates the accommodation of hydraulic oil and provides corresponding space for the accommodation of hydraulic oil.

[0078] like Figures 1 to 8As shown, a pulling buffer pressure plate 306 is slidingly installed in the pulling buffer pressure chamber 305, which can slide in the pulling buffer pressure chamber 305 and can squeeze the hydraulic oil in the pulling buffer pressure chamber 305. By sliding in the hydraulic oil, the displacement speed of the pulling buffer pressure plate 306 can be effectively slowed down.

[0079] Among them, a pulling buffer connecting rod 307 is fixedly installed on one side of the pulling buffer pressure plate 306, which is connected to the supporting pulling connecting plate 201. The rotation of the supporting pulling connecting plate 201 can pull the pulling buffer connecting rod 307, so that the pulling buffer pressure plate 306 can be displaced, squeezing the hydraulic oil in the pulling buffer pressure chamber 305, and the pulling buffer connecting rod 307 is set through the pulling buffer pressure chamber 305.

[0080] like Figures 1 to 10 As shown, a pulling buffer sealing ring 308 is installed between the pulling buffer connecting rod 307 and the pulling buffer pressure chamber 305, which improves the sealing between the pulling buffer connecting rod 307 and the pulling buffer pressure chamber 305 and reduces the possibility of hydraulic oil leakage in the pulling buffer pressure chamber 305.

[0081] In addition, the pull-buffer connecting rod 307 is rotatably installed with the support-pull connecting plate 201, so that the rotation of the support-pull connecting plate 201 will not cause the support-pull connecting plate 201 to separate from the pull-buffer connecting rod 307, reducing the probability of the support-pull connecting plate 201 separating from the pull-buffer connecting rod 307, so that the rotation of the support-pull connecting plate 201 can better drive the displacement of the pull-buffer connecting rod 307.

[0082] In addition, a plurality of flow grooves are drilled on the pulling buffer pressure plate 306 to facilitate the circulation of the hydraulic oil, so that the hydraulic oil can slow down the displacement speed of the pulling buffer pressure plate 306 without causing the pulling buffer pressure plate 306 to stop displacement.

[0083] like Figures 1 to 11 As shown, a pressure support mechanism 4 is fixedly installed on the welding robot base 1. The pressure support mechanism 4 includes a pressure support accommodating chamber 401, which facilitates the sliding of the pressure support positioning rod 402 and provides corresponding guidance for the sliding of the pressure support positioning rod 402. At the same time, it can also accommodate hydraulic oil.

[0084] In addition, a pressure support positioning rod 402 is slidably installed in the pressure support accommodating chamber 401, which can support the welding robot base 1 so that the welding robot base 1 can squeeze the pressure support positioning rod 402 after rotating, so that the pressure support positioning rod 402 can slow down the rotation speed of the welding robot base 1.

[0085] In addition, a number of pressure support springs 403 are installed between the pressure support positioning rod 402 and the pressure support containing chamber 401, which can squeeze the pressure support positioning rod 402 and provide the pressure support positioning rod 402 with a force to always slide upward, so that the pressure support positioning rod 402 can better support the welding robot base 1. At the same time, the pressure support positioning rod 402 can rise after being free from force, providing better buffering for the welding robot base 1.

[0086] Among them, several pressure grooves are carved on the pressure support positioning rod 402, which facilitates the displacement of the pressure support positioning rod 402, so that the hydraulic oil can slow down the sliding speed of the pressure support positioning rod 402 without causing the pressure support positioning rod 402 to stagnate and shift.

[0087] like Figures 1 to 9 As shown, multiple pairs of pressure support guide rods 404 are fixedly installed on the welding robot base 1, which facilitates the sliding of the pressure support positioning block 405 and provides corresponding guidance for the sliding of the pressure support positioning block 405, thereby reducing the probability of the pressure support positioning block 405 being detached.

[0088] In addition, a pressure support positioning block 405 is slidably mounted on the pressure support guide rod 404 to support the pressure support spring piece 407 , so that the deformation process of the pressure support spring piece 407 can drive the sliding of the pressure support positioning block 405 .

[0089] In addition, a pressure compression spring 406 is installed between the pressure support positioning block 405 and the pressure support guide rod 404, which can be squeezed by the pressure support positioning block 405 to buffer the pressure support positioning block 405 and slow down the sliding speed of the pressure support positioning block 405. A pressure support spring 407 is installed between a pair of pressure support positioning blocks 405 to support the welding robot base 1 and help the balance of the welding robot base 1.

[0090] A method for using a shell welding device for water pump production includes the following steps:

[0091] S1. When the power device 101 slides on the guide rail 102, once the welding robot is hit, the welding robot base 1 will tilt, and the welding robot base 1 will tilt along the direction of the track.

[0092] S2. During the tilting process of the welding robot base 1, the support and pull connecting plate 201 on the force-bearing side will be pulled, and pressure will be applied to the support and pull connecting plate 201 on the other side. At this time, the support and pull connecting plate 201 on the force-bearing side will be guided by the support and pull guide rod 202 to slide, and squeeze the support and pull sliding rod 205, so that the support and pull connecting plate 201 on the force-bearing side is buffered and pulled, thereby reducing the tilting amplitude of the welding robot base 1.

[0093] S3. The supporting and pulling connecting plate 201 on the other side will be supported by the supporting and pulling guide rod 202, so that the tilting of the welding robot base 1 is supported. At the same time, the supporting and pulling connecting plate 201 on the force-bearing side will pull the pulling buffer connecting rod 307, so that the pulling buffer pressure plate 306 slides in the pulling buffer pressure chamber 305, and squeezes the hydraulic oil in the pulling buffer pressure chamber 305, slowing down the sliding displacement speed of the pulling buffer pressure plate 306, and reducing the tilting and rotation speed of the welding robot base 1.

[0094] S4. At the same time, when the power device 101 slides on the guide rail 102, the pulling buffer electromagnet 303 will always attract the pulling buffer support frame 301. When the welding robot is slightly collided, the welding robot base 1 is fixed by the pulling buffer electromagnet 303, so that the welding robot base 1 will not tilt.

[0095] S5. When the welding robot base 1 is tilted and then rotated, pressure is applied to the pressure support positioning rod 402 and the pressure support spring 407. The compression of the pressure support spring 403 and the hydraulic oil in the pressure support containing chamber 401 slow down the descending speed of the welding robot base 1. At the same time, the pressure support spring 407 and the pressure compression spring 406 further buffer the welding robot base 1, and the pulling buffer pad 302 is used to protect the welding robot base 1.
