Description

Technical Field

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

[0002] A water pump housing welding device is a device used for the processing and manufacturing of water pump housings. Its main function is to connect different components of the water pump housing through a welding process to ensure the overall structural strength and sealing performance of the housing. Such a device usually includes welding equipment, a positioning mechanism, a cooling system, etc., for optimizing the welding process and improving the welding quality.

[0003] A water pump housing usually consists of: a bottom plate, a fixing mechanism, a moving device, a welding torch, a welding unit, a cooling system, a positioning mechanism, and auxiliary components. The water pump housing welding device works in cooperation through these components to achieve efficient and high-quality welding effects.

[0004] With the development, the manual welding method has gradually been replaced by automation, and the use range of welding robots has gradually expanded. Although most welding robots are fixedly installed, when movement is required, they still rely on a motion system. At present, the development of the free motion system is not ideal, and mainly relies on rails for movement.

[0005] Currently, when a welding robot welds the housing of a water pump, the welding robot needs to move along the track. During the displacement process, due to programming and other issues, it may collide with a fixing frame or a workpiece. The existing welding robots do not have a corresponding protection mechanism, and such impacts are likely to cause damage to the welding robot, and even the base tilts. This not only reduces the service life of the welding robot, but also causes the center of gravity of the welding robot to shift. Seriously, it may even cause the welding robot to tip over and be damaged, which is not conducive to long-term use.

[0006] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0008] To achieve the above purpose, the technical solution provided by a specific embodiment of the present invention is as follows: A housing welding device for water pump production, comprising: a welding robot base, a pressure support mechanism, a pair of pulling and buffering mechanisms, and a pair of supporting and pulling mechanisms; A power device is provided on the lower side of the welding robot base, and a guide rail is slidably installed on the lower side of the power device; A pair of supporting and pulling mechanisms are installed between the welding robot base and the power device.

A supporting and pulling pressure spring is installed between the supporting and pulling sliding rod and the supporting and pulling accommodating bin; A pair of pulling and buffering mechanisms are fixedly installed on the power device; A pressure support mechanism is fixedly installed on the welding robot base.

[0009] 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; The support and pull shaft seat penetrates 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 better connect with the welding robot base, and enables the support and pull connecting plate to rotate better; A first support and pull bearing is installed between the support and pull shaft seat and the support and pull connecting plate, which reduces the friction between the support and pull connecting plate and the support and pull shaft seat, improves the service life of the support and pull connecting plate and the support and pull shaft seat, reduces the probability of damage to the support and pull connecting plate and the support and pull shaft seat, and enables the support and pull connecting plate to better fix the position of the welding robot base.

[0010] In one or more embodiments of the present invention, a displacement groove matching the support and pull guide rod is drilled inside 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, enables the support and pull guide rod to more conveniently compress the support and pull sliding rod, and enables the support and pull guide rod to jointly pull the support and pull connecting plate with the support and pull shaft seat; A second bearing for support and pulling is sleeved outside the support and pulling guide rod, which reduces the friction between the support and pulling guide rod and the support and pulling connecting plate, extends the service life between the support and pulling guide rod and the support and pulling connecting plate, improves the use effect of the support and pulling guide rod and the support and pulling connecting plate, and makes the sliding of the support and pulling guide rod in the support and pulling connecting plate smoother; The support and pulling positioning rod is fixedly installed with the power device, which improves the balance of the support and pulling positioning rod, reduces the probability of the support and pulling positioning rod tilting, improves the stability of the support and pulling positioning rod, enables the support and pulling positioning rod to better fix the support and pulling guide rod, and enables the support and pulling guide rod to better guide the support and pulling connecting plate.

[0011] In one or more embodiments of the present invention, the pulling buffer mechanism includes a pulling buffer support frame. A pair of pulling buffer support frames can improve the stability of the welding robot base and synchronously reduce the probability of the welding robot base tilting; A pulling buffer soft pad is fixedly installed on the pulling buffer support frame, which increases 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; A pulling buffer electromagnet is provided on the upper side of the pulling buffer support frame, which can attract the pulling buffer support frame, reduce the tilting amplitude of the welding robot base, reduce the probability of the welding robot base tilting, and enable the welding robot installed on the welding robot base not to shake after being slightly impacted; A receiving groove matching the pulling buffer electromagnet is dug in the welding robot base, which facilitates the installation of the pulling buffer electromagnet, provides a corresponding installation position for the pulling buffer electromagnet, reduces the probability of the pulling buffer electromagnet shaking, and synchronously reduces the probability of the pulling buffer electromagnet detaching.

[0012] In one or more embodiments of the present invention, a pulling buffer filter screen is provided on the lower side of the pulling buffer electromagnet. When the pulling buffer electromagnet attracts the pulling buffer support frame, it will continuously attract iron-containing debris, and the pulling buffer filter screen can block these debris; A blocking groove matching the pulling buffer filter screen is dug in the welding robot base. The pulling buffer electromagnet can not only attract the pulling buffer filter screen to make it more stable and reduce the probability of the pulling buffer filter screen detaching, but also enable the user to clean the debris by disassembling the pulling buffer filter screen, and the blocking groove facilitates the installation of the pulling buffer filter screen; One side of the pulling buffer support frame is rotatably installed with a pulling buffer hydraulic chamber, which facilitates the installation of the pulling buffer pressure plate, provides corresponding space for the installation of the pulling buffer pressure plate, and at the same time facilitates the accommodation of hydraulic oil, providing corresponding space for the accommodation of hydraulic oil.

[0013] In one or more embodiments of the present invention, a pulling buffer pressure plate is slidably installed in the pulling buffer hydraulic chamber, which can slide in the pulling buffer hydraulic chamber, can squeeze the hydraulic oil in the pulling buffer hydraulic chamber, and can effectively slow down the displacement speed of the pulling buffer pressure plate by sliding in the hydraulic oil. One side of the pulling buffer pressure plate is fixedly installed with a pulling buffer connecting rod, which connects 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 squeeze the hydraulic oil in the pulling buffer hydraulic chamber. The pulling buffer connecting rod penetrates through the pulling buffer hydraulic chamber.

[0014] 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 hydraulic chamber, which improves the sealing performance between the pulling buffer connecting rod and the pulling buffer hydraulic chamber and reduces the possibility of hydraulic oil leakage in the pulling buffer hydraulic chamber. The pulling buffer connecting rod is rotatably installed with the supporting pulling connecting plate, so that the rotation of the supporting pulling connecting plate will not cause the separation of the supporting pulling connecting plate and the pulling buffer connecting rod, reduces the probability of the supporting pulling connecting plate separating from the pulling buffer connecting rod, and enables the rotation of the supporting pulling connecting plate to better drive the displacement of the pulling buffer connecting rod. A number of flow grooves are formed on the pulling buffer pressure plate, which facilitates the flow of 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.

[0015] In one or more embodiments of the present invention, the pressure support mechanism includes a pressure support accommodation chamber, which facilitates the sliding of the pressure support positioning rod, provides corresponding guidance for the sliding of the pressure support positioning rod, and at the same time can also accommodate hydraulic oil. A pressure support positioning rod is slidably installed in the pressure support accommodation chamber, which can support the welding robot base. 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. A number of pressure support springs are installed between the pressure support positioning rod and the pressure support receiving bin, which can squeeze the pressure support positioning rod, provide an upward sliding force for the pressure support positioning rod all the time, enable the pressure support positioning rod to better support the welding robot base. At the same time, after the pressure support positioning rod is not stressed, it can rise to provide better buffering for the welding robot base; A number of pressure grooves are drilled on the pressure support positioning rod, which facilitates the displacement of the pressure support positioning rod, enables 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.

[0016] In one or more embodiments of the present invention, multiple pairs of pressure support guide rods are fixedly installed on the welding robot base, which facilitates the sliding of the pressure support positioning block, provides corresponding guidance for the sliding of the pressure support positioning block, and reduces the probability of the pressure support positioning block detaching; A pressure support positioning block is slidably installed on the pressure support guide rod, which can support the pressure support elastic sheet, so that the deformation process of the pressure support elastic sheet can drive the sliding of the pressure support positioning block; 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, so that the pressure support positioning block is buffered and the sliding speed of the pressure support positioning block is slowed down. A pressure support elastic sheet is installed between a pair of the pressure support positioning blocks, which can support the welding robot base and help with the balance of the welding robot base.

[0017] A method for using a housing welding device for water pump production includes the following steps: S1. When the power device slides on the rail, once the welding robot is impacted, the welding robot base will tilt, and the welding robot base will tilt along the direction of the rail; During the tilting process of the welding robot base, it will pull the support pulling connecting plate on the stressed side and press the support pulling connecting plate on the other side. At this time, the support pulling connecting plate on the stressed side will slide under the guidance of the support pulling guide rod and squeeze the support pulling sliding rod, so that the support pulling connecting plate on the stressed side is buffered and pulled, reducing the tilting amplitude of the welding robot base; The support pulling connecting plate on the other side will be supported by the support pulling guide rod to support the tilting of the welding robot base. At the same time, the support pulling connecting plate on the stressed side will pull the pulling buffer connecting rod, so that the pulling buffer sealing ring slides and displaces in the pulling buffer hydraulic chamber and squeezes the hydraulic oil in the pulling buffer hydraulic chamber, slowing down the sliding displacement speed of the pulling buffer sealing ring and reducing the tilting and rotation speed of the welding robot base; S4. Meanwhile, 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 collided, the base of the welding robot is fixed by the pulling buffer electromagnet, so that the base of the welding robot will not tilt. S5. When the base of the welding robot tilts and rotates, it will exert pressure on the pressure support positioning rod and the pressure support elastic sheet. Through the compression of the pressure support spring and the hydraulic oil in the pressure support accommodation chamber, the descending speed of the base of the welding robot is slowed down. At the same time, through the pressure support elastic sheet and the pressure compression spring, the base of the welding robot is further buffered, and at the same time, the base of the welding robot is protected in cooperation with the pulling buffer soft pad.

[0018] Compared with the prior art, the shell welding device for water pump production and its use method of the present invention, through the setting of corresponding mechanisms, when the welding robot collides during orbital displacement, the damage suffered by the welding robot is reduced, and the probability of the base tilting is reduced. This not only improves the service life of the welding robot, but also reduces the probability of the center of gravity of the welding robot shifting. Furthermore, the probability of the welding robot tipping over and being damaged is reduced, which is more conducive to long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

After being impacted, the support pulling connecting plate 201 on the stressed side can rotate, and the support pulling connecting plate 201 on the other side can support the welding robot base 1 to make the welding robot base 1 rotate instead of sliding, which facilitates the buffering of the welding robot base 1.

[0025] Among them, a support pulling guide rod 202 is provided inside the support pulling connecting plate 201, which can squeeze the support pulling sliding rod 205 and at the same time guide the rotation of the support pulling connecting plate 201.

A support pulling sliding rod 205 is slidably installed inside the support pulling accommodating bin 204, which can squeeze the support pulling pressure spring 206. A support pulling pressure spring 206 is installed between the support pulling sliding rod 205 and the support pulling accommodating bin 204.

[0027] As Figures 1 to 8 shown in the figure, support pulling shaft seats 207 are fixedly installed on both sides of the welding robot base 1, which facilitates the rotation of the support pulling connecting plate 201, provides corresponding assistance for the connection between the support pulling connecting plate 201 and the welding robot base 1, reduces the probability of the support pulling connecting plate 201 detaching 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 pulling connecting plate 201 more stable.

[0028] Among them, the support pulling shaft seat 207 penetrates through the support pulling connecting plate 201, which facilitates the rotation of the support pulling connecting plate 201, enables the support pulling connecting plate 201 to better connect the welding robot base 1, and enables the support pulling connecting plate 201 to rotate better.

[0029] In addition, a first support pulling bearing 208 is installed between the support pulling shaft seat 207 and the support pulling connection plate 201, which reduces the friction between the support pulling connection plate 201 and the support pulling shaft seat 207, extends the service life of the support pulling connection plate 201 and the support pulling shaft seat 207, decreases the probability of damage to the support pulling connection plate 201 and the support pulling shaft seat 207, and enables the support pulling connection plate 201 to better fix the position of the welding robot base 1.

[0030] As Figures 1 to 8 shown, a displacement groove matching the support pulling guide rod 202 is formed in the support pulling connection plate 201, which facilitates the displacement of the support pulling guide rod 202, enables the support pulling guide rod 202 to guide the rotation of the support pulling connection plate 201, makes it easier for the support pulling guide rod 202 to compress the support pulling sliding rod 205, and enables the support pulling guide rod 202 and the support pulling shaft seat 207 to jointly pull the support pulling connection plate 201.

[0031] In addition, a second support pulling bearing 209 is sleeved outside the support pulling guide rod 202, which reduces the friction between the support pulling guide rod 202 and the support pulling connection plate 201, extends the service life between the support pulling guide rod 202 and the support pulling connection plate 201, improves the use effect of the support pulling guide rod 202 and the support pulling connection plate 201, and makes the sliding of the support pulling guide rod 202 in the support pulling connection plate 201 smoother.

[0032] In addition, the support pulling positioning rod 203 is fixedly installed with the power device 101, which improves the balance of the support pulling positioning rod 203, reduces the probability of the support pulling positioning rod 203 tilting, enhances the stability of the support pulling positioning rod 203, enables the support pulling positioning rod 203 to better fix the support pulling guide rod 202, and enables the support pulling guide rod 202 to better guide the support pulling connection plate 201.

[0033] As Figures 1 to 5 shown, a pair of pulling buffer mechanisms 3 are fixedly installed on the power device 101. The pulling buffer mechanism 3 includes a pulling buffer support frame 301. The pair of pulling buffer support frames 301 can enhance the stability of the welding robot base 1 and synchronously reduce the probability of the welding robot base 1 tilting.

[0034] Among them, a pulling buffer soft pad 302 is fixedly installed on the pulling buffer support frame 301, which increases 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 enhances the stability of the welding robot base 1.

[0035] 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, reducing the degree of inclination of the welding robot base 1, decreasing the probability of the welding robot base 1 tilting, and ensuring that the welding robot installed on the welding robot base 1 does not shake after being slightly impacted.

[0036] In addition, a receiving groove matching the pulling buffer electromagnet 303 is dug in the welding robot base 1, facilitating the installation of the pulling buffer electromagnet 303, providing a corresponding installation position for the pulling buffer electromagnet 303, reducing the probability of the pulling buffer electromagnet 303 shaking, and synchronously reducing the probability of the pulling buffer electromagnet 303 detaching.

[0037] As Figures 1 to 7 shown, a pulling buffer filter screen 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 continuously attracts iron-containing debris, and the pulling buffer filter screen 304 can block these debris.

[0038] In addition, a blocking groove matching the pulling buffer filter screen 304 is dug in the welding robot base 1. The pulling buffer electromagnet 303 can not only attract the pulling buffer filter screen 304, making the pulling buffer filter screen 304 more stable and reducing the probability of the pulling buffer filter screen 304 detaching, but also enables the user to clean the debris by disassembling the pulling buffer filter screen 304, and the blocking groove facilitates the installation of the pulling buffer filter screen 304.

[0039] Among them, a pulling buffer hydraulic chamber 305 is rotatably installed on one side of the pulling buffer support frame 301, facilitating the installation of the pulling buffer pressure plate 306, providing a corresponding space for the installation of the pulling buffer pressure plate 306, and at the same time facilitating the accommodation of hydraulic oil and providing a corresponding space for the accommodation of hydraulic oil.

[0040] As Figures 1 to 8 shown, a pulling buffer pressure plate 306 is slidably installed in the pulling buffer hydraulic chamber 305, which can slide in the pulling buffer hydraulic chamber 305, squeeze the hydraulic oil in the pulling buffer hydraulic chamber 305, and effectively slow down the displacement speed of the pulling buffer pressure plate 306 by sliding in the hydraulic oil.

[0041] Among them, a pulling buffer connecting rod 307 is fixedly installed on one side of the pulling buffer pressure plate 306, connecting the supporting pulling connecting plate 201. The rotation of the supporting pulling connecting plate 201 can pull the pulling buffer connecting rod 307, enabling the pulling buffer pressure plate 306 to displace and squeeze the hydraulic oil in the pulling buffer hydraulic chamber 305. The pulling buffer connecting rod 307 penetrates through the pulling buffer hydraulic chamber 305.

[0042] As Figures 1 to 10 shown, a pulling buffer sealing ring 308 is installed between the pulling buffer connecting rod 307 and the pulling buffer hydraulic chamber 305, which improves the sealing performance between the pulling buffer connecting rod 307 and the pulling buffer hydraulic chamber 305 and reduces the possibility of hydraulic oil leakage in the pulling buffer hydraulic chamber 305.

[0043] In addition, the pulling buffer connecting rod 307 is rotatably installed with the supporting pulling connecting plate 201, so that the rotation of the supporting pulling connecting plate 201 will not cause the separation of the supporting pulling connecting plate 201 and the pulling buffer connecting rod 307, reducing the probability of the supporting pulling connecting plate 201 detaching from the pulling buffer connecting rod 307 and enabling the rotation of the supporting pulling connecting plate 201 to better drive the displacement of the pulling buffer connecting rod 307.

[0044] In addition, a number of flow grooves are drilled on the pulling buffer pressure plate 306, which facilitates the flow of hydraulic oil and enables the hydraulic oil to slow down the displacement speed of the pulling buffer pressure plate 306 without causing the pulling buffer pressure plate 306 to stop moving.

[0045] As Figures 1 to 11 shown, a pressure support mechanism 4 is fixedly installed on the welding robot base 1. The pressure support mechanism 4 includes a pressure support receiving chamber 401, which facilitates the sliding of the pressure support positioning rod 402, provides corresponding guidance for the sliding of the pressure support positioning rod 402, and at the same time can also accommodate hydraulic oil.

[0046] In addition, a pressure support positioning rod 402 is slidably installed in the pressure support receiving chamber 401, which can support the welding robot base 1. After the welding robot base 1 rotates, the pressure support positioning rod 402 can be squeezed, enabling the pressure support positioning rod 402 to slow down the rotation speed of the welding robot base 1.

[0047] In addition, a number of pressure support springs 403 are installed between the pressure support positioning rod 402 and the pressure support receiving chamber 401, which can squeeze the pressure support positioning rod 402, provide a force for the pressure support positioning rod 402 to always slide upward, enable the pressure support positioning rod 402 to better support the welding robot base 1, and at the same time enable the pressure support positioning rod 402 to rise after being unloaded, providing better buffering for the welding robot base 1.

[0048] Among them, a number of pressure grooves are drilled on the pressure support positioning rod 402, which facilitates the displacement of the pressure support positioning rod 402 and enables the hydraulic oil to slow down the sliding speed of the pressure support positioning rod 402 without causing the pressure support positioning rod 402 to stagnate.

[0049] AsFigures 1 to 9 As shown, multiple pairs of pressure support guide rods 404 are fixedly installed on the welding robot base 1, facilitating the sliding of the pressure support positioning block 405, providing corresponding guidance for the sliding of the pressure support positioning block 405, and reducing the probability of the pressure support positioning block 405 detaching.

[0050] In addition, a pressure support positioning block 405 is slidably installed on the pressure support guide rod 404, which can support the pressure support elastic piece 407, enabling the deformation process of the pressure support elastic piece 407 to drive the sliding of the pressure support positioning block 405.

[0051] Furthermore, 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, buffering the pressure support positioning block 405 and slowing down the sliding speed of the pressure support positioning block 405. A pressure support elastic piece 407 is installed between a pair of pressure support positioning blocks 405, which can support the welding robot base 1 and help with the balance of the welding robot base 1.

[0052] A usage method of a shell welding device for water pump production includes the following steps: S1. When the power device 101 slides on the guide rail 102, once the welding robot is impacted, the welding robot base 1 will tilt, and the welding robot base 1 will tilt along the direction of the track.

[0053] S2. During the tilting process of the welding robot base 1, it will pull the support pulling connecting plate 201 on the stressed side and exert pressure on the support pulling connecting plate 201 on the other side. At this time, the support pulling connecting plate 201 on the stressed side will slide under the guidance of the support pulling guide rod 202 and squeeze the support pulling sliding rod 205, buffering and pulling the support pulling connecting plate 201 on the stressed side and reducing the tilting amplitude of the welding robot base 1.

[0054] S3. The support pulling connecting plate 201 on the other side will be supported by the support pulling guide rod 202 to support the tilting of the welding robot base 1. At the same time, the support pulling connecting plate 201 on the stressed side will pull the pulling buffer connecting rod 307, causing the pulling buffer sealing ring 308 to slide and displace in the pulling buffer hydraulic chamber 305 and squeeze the hydraulic oil in the pulling buffer hydraulic chamber 305, slowing down the sliding displacement speed of the pulling buffer sealing ring 308 and reducing the tilting and rotation speeds of the welding robot base 1.

[0055] S4. Meanwhile, when the power unit 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.

[0056] S5. When the welding robot base 1 tilts and then rotates, it will exert pressure on the pressure support positioning rod 402 and the pressure support elastic sheet 407. Through the compression of the pressure support spring 403 and the hydraulic oil in the pressure support accommodation chamber 401, the descending speed of the welding robot base 1 is slowed down. At the same time, through the pressure support elastic sheet 407 and the pressure compression spring 406, the welding robot base 1 is further buffered, and at the same time, the pulling buffer soft pad 302 is used to protect the welding robot base 1.

10. A method for using a casing welding device for producing a water pump according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When the power device slides on the guide rail, once the welding robot is hit, the base of the welding robot will tilt along the direction of the track; 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 slide under the guidance of the support and pull guide rod, 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; S3. The support and pulling connecting plate on the other side will be supported by the support and pulling guide rod, so that the inclination 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 sealing ring slides in the pulling buffer pressure chamber, and squeezes the hydraulic oil in the pulling buffer pressure chamber, slowing down the sliding displacement speed of the pulling buffer sealing ring, and reducing the inclination and rotation speed of the welding robot base; 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 collided, the welding robot base is fixed by the pulling buffer electromagnet so that the welding robot base will not tilt; 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 buffer the welding robot base, and the pulling buffer pad is used to protect the welding robot base.
