Description

Technical Field

[0001] The utility model belongs to the technical field of automobile part welding, and particularly relates to a robot welding device for automobile part processing. Background Art

[0002] Welding technology is an operation method that uses welding equipment to connect two or more materials into a whole under high temperature or high pressure conditions. Welding equipment is required for the processing of automobile parts, and currently, most automobile parts are welded by robots or robotic arms.

[0003] In the prior art, a robot welding device for automobile part processing with the patent number CN219665592U includes a workbench. Universal ball bearings are arranged in an array in the first fixing block and the second fixing block, and in the third fixing block and the fourth fixing block; through the cooperation of the first bracket, the first support block, the second support block, the positioning block, the slider, the second bracket, the third bracket, the first fixing block, the second fixing block, the third fixing block, the fourth fixing block and the universal ball bearings, the first bracket, the first support block and the second support block can be moved. During the movement of the first bracket, the first support block and the second support block, the positions of the first fixing block and the second fixing block, and the third fixing block and the fourth fixing block can be adjusted according to the length of the tubular part, so as to position and fix the tubular part, and further facilitate the welding of the tubular part.

[0004] The above device has the following deficiencies:

[0005] When the above device fixes and clamps automobile pipe fittings, the two ends of the pipe fittings on both sides need to be respectively inserted into the first fixing seat and the second fixing seat for plug-in cooperation. The diameter of the clamped pipe fittings is fixed. When fixing pipe fittings with other diameters, the sizes of the first fixing seat and the second fixing seat need to be replaced, and the process is cumbersome. A large number of size types of the first fixing seat and the second fixing seat are required, which affects the welding process of the device for pipe fittings of different sizes.

[0006] When the above device fixes the surfaces of the other ends of the pipe fittings on both sides, the first fixing block, the second fixing block, the third fixing block and the fourth fixing block are respectively used to fix the surfaces of the pipe fittings. During the fixing process, the bolts are manually tightened to fix them. This is not only troublesome but also can only fix pipe fittings of one size type. When fixing pipe fittings with other diameters, other sizes need to be replaced, and the process is cumbersome. Content of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, the present utility model provides a robotic welding device for automotive component processing. This device can perform welding clamping on pipe fittings of various different diameters, effectively expanding the processing range of the device.

[0008] In order to achieve the above object, the present utility model provides the following technical solutions: A robotic welding device for automotive component processing, including a workbench, symmetrically arranged clamping members, two groups of symmetrically arranged sliders and two mounting seats. Circular baffles and annular covers are respectively installed on both sides of the clamping member. A cylindrical groove is provided inside the clamping member, and a number of first grooves are annularly provided on the inner wall of the cylindrical groove. Trapezoidal clamping blocks are slidably arranged in the first grooves. Symmetrically fixed springs are connected between the lower end surfaces of the clamping blocks and the bottom surfaces of the first grooves. Square sliding grooves are provided on the upper surfaces of the sliders. L-shaped support rods are slidably arranged in the sliding grooves. A second spring is fixedly connected between the lower end surfaces of the L-shaped support rods and the inner bottom surfaces of the sliding grooves. A second rotating shaft is rotatably arranged at the outer end of the L-shaped support rod, and a rubber wheel is fixed on the surface of the second rotating shaft.

[0009] Optionally, a first rotating shaft is symmetrically rotatably arranged between the two mounting seats. Rubber wheels are fixedly arranged on the surfaces of the two first rotating shafts, and there is a gap between the two rubber wheels.

[0010] Optionally, a second groove is provided on the upper surface of the clamping block. A rubber block is fixedly arranged in the second groove, and anti-slip protrusions are arranged on the outer surface of the rubber block.

[0011] Optionally, two groups of first fixing seats are symmetrically fixedly arranged on the upper surface of the workbench. A first bidirectional screw is rotatably arranged between the two first fixing seats. The two sliders are symmetrically threaded on the surface of the first bidirectional screw, and the sliders slide on the surface of the workbench.

[0012] Optionally, two second fixing seats are symmetrically fixedly arranged on the upper surface of the middle part of the workbench. A second screw is rotatably arranged between the two second fixing seats. A sliding seat is threaded on the surface of the second screw. The sliding seat slides on the surface of the workbench. A third motor is fixedly installed on the outer side surface of the sliding seat, and a grinding wheel is fixedly arranged on the surface of the output shaft of the third motor.

[0013] Optionally, telescopic cylinders are symmetrically fixedly arranged on both sides of the upper surface of the workbench. A motor seat is fixedly arranged at the outer end of the piston rod of the telescopic cylinder. A second motor is fixedly installed in the motor seat, and the baffle is fixed to the output shaft of the second motor.

[0014] In summary, compared with the prior art, a robotic welding device for automotive component processing provided by the present utility model has the following beneficial effects:

[0015] In the present utility model, when the clamping block is squeezed by the pipe fitting, the first spring is compressed. At this time, several annularly arranged clamping blocks can form a clamp on the surface of the pipe fitting through the first spring below, so that the clamping member can drive the rotation of the pipe fitting, facilitating the external welding robot to better perform welding processing on the pipe fitting, and can clamp pipe fittings with various different diameters, effectively expanding the processing range of the device.

[0016] In the present utility model, after one end of the pipe fitting is placed between the two lower rubber wheels, the motor one is started to drive the rotation of the bidirectional screw, so that the two sliders on both sides move relatively. As the sliders move, the two upper rubber wheels will gradually approach and contact the surface of the pipe fitting. Since the outer surface of the pipe fitting is circular, during the movement of the sliders, the L-shaped support rod will rise along the outer surface shape of the pipe fitting. At this time, the second spring is stretched, and then through the elastic force of the second spring, the two upper rubber wheels press down on the surface of the pipe fitting, cooperating with the two lower rubber wheels to clamp one end surface of the pipe fitting, and this method can clamp pipe fittings with various different diameters.

[0017] In the present utility model, after the pipe fitting is welded, the rotation of the screw two drives the movement of the sliding seat, making the grinding wheel approach the welding position, and then cooperating with the motor two to drive the rotation of the pipe fitting, so that the grinding wheel grinds the welding position of the pipe fitting, reducing the subsequent processing procedures for the pipe fitting and improving the processing efficiency of the pipe fitting welding.

[0027] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Embodiment 1:

[0028] Refer to Figures 1-7 , a robot welding device for automobile part processing, including a workbench 1. The first clamping component 2 and the second clamping component 3 are symmetrically arranged on the surface of the workbench 1. One end surface of the pipe fitting 5 is fixed by the second clamping component 3 on one side. At this time, the corresponding ends of the two pipe fittings 5 are already in contact. Then, the other end of the pipe fitting 5 is fixed by the first clamping component 2. Then, the connection part of the two pipe fittings 5 is welded and processed by an external welding robot. The welding robot here is a prior art, so there is no need to describe and draw it in detail here and in the drawings.

[0029] Refer to Figure 2 , the first clamping component 2 includes a telescopic cylinder 21 and a clamping piece 23. The telescopic cylinder 21 is fixedly installed on the surface of the workbench 1 by bolts. The outer end of the piston rod of the telescopic cylinder 21 is fixedly provided with a motor base 211, and a second motor 22 is fixedly installed in the motor base 211.

[0030] Refer to Figure 2 , at the position corresponding to the motor base 211 on the upper surface of the workbench 1, a slide rail 11 is fixedly provided. The motor base 211 slides on the surface of the slide rail 11 and also slides on the surface of the workbench 1. The telescopic cylinder 21 is used to drive the motor base 211 to slide on the surface of the workbench 1. The slide rail 11 can ensure the stability of the motor base 211 during sliding.

[0031] Refer to Figure 2, circular baffles 24 and annular covers 25 are respectively arranged on both sides of the clamping member 23. The baffle 24 and the annular cover 25 are both fixed to the clamping member 23 by bolts. The baffle 24 is fixed to the output shaft of the second motor 22. The clamping member 23 can be driven to rotate by the second motor 22, and the clamping member 23 can also be driven to move above the workbench 1 by the telescopic cylinder 21.

[0032] Reference Figure 5 , a cylindrical groove 232 is formed in the clamping member 23. A plurality of first grooves 231 are annularly formed on the inner wall of the cylindrical groove 232. A trapezoidal clamping block 26 is slidably arranged in the first groove 231. The clamping block 26 is made of metal to facilitate the extrusion of the pipe fitting 5. The inclined surface of the clamping block 26 corresponds to the entrance of the annular cover 25, so that one end of the pipe fitting 5 can pass through the annular cover 25 and then contact the inclined surface of the clamping block 26.

[0033] Reference Figure 5 , a first spring 261 is symmetrically and fixedly connected between the lower end surface of the clamping block 26 and the bottom surface of the first groove 231. When the clamping block 26 is extruded by the pipe fitting 5, the first spring 261 is compressed. At this time, several annularly arranged clamping blocks 26 can form a clamping force on the surface of the pipe fitting 5 through the first spring 261 below, so that the clamping member 23 can drive the rotation of the pipe fitting 5, which is convenient for the external welding robot to perform better welding processing on the pipe fitting 5, and can clamp various pipe fittings 5 with different diameters, effectively improving the processing range of the equipment.

[0034] Reference Figure 7 , a second groove 262 is formed on the upper surface of the clamping block 26. A rubber block 27 is fixedly arranged in the second groove 262. The outer surface of the rubber block 27 is provided with convex blocks for anti-slip. When one end of the pipe fitting 5 passes through the inclined surface of the clamping block 26, it will enter the surface of the rubber block 27, and at this time, the clamping of one end surface of the pipe fitting 5 is completed.

[0035] Reference Figure 1 、 3 , the second clamping assembly 3 includes symmetrically arranged first fixing seats 311, symmetrically arranged mounting seats 33 and four rubber wheels 35. The first fixing seats 311 and the mounting seats 33 are both fixedly installed on the upper surface of the workbench 1 by bolts. The two mounting seats 33 are arranged between the two first fixing seats 311. A first motor 6 is fixedly arranged on the outer surface of one of the first fixing seats.

[0036] Reference Figure 3 , a first rotating shaft 34 is symmetrically and rotatably arranged between the two mounting seats 33. The two rubber wheels 35 are fixedly installed on the surface of the first rotating shaft 34, and there is a certain interval between the two rubber wheels 35 to prevent the two rubber wheels 35 from affecting each other's rotation. These two rubber wheels 35 are used as the support for the lower surface of one end of the pipe fitting 5.

[0037] Reference Figure 3 Between two fixed seats 311, a first bidirectional screw 31 is rotatably arranged. The output shaft of the first motor 6 is fixed to one end of the first bidirectional screw 31. The surface of the first bidirectional screw 31 is symmetrically threaded with sliders 32. The sliders 32 slide on the surface of the workbench 1. A square chute 321 is formed on the upper surface of the slider 32. An L-shaped support rod 36 is slidably arranged in the chute 321. A second spring 361 is fixedly connected between the lower end surface of the L-shaped support rod 36 and the inner bottom surface of the chute 321. A second rotating shaft 37 is rotatably arranged at the outer end of the L-shaped support rod 36. A rubber wheel 35 is also fixed on the surface of the second rotating shaft 37.

[0038] Further, after one end of the pipe fitting 5 is placed between the two lower rubber wheels 35, start the first motor 6 to drive the rotation of the bidirectional screw, so that the two sliders 32 move relative to each other. As the sliders 32 move, the two upper rubber wheels 35 will gradually approach and contact the surface of the pipe fitting 5. Since the outer surface of the pipe fitting 5 is circular, during the movement of the slider 32, the L-shaped support rod 36 will rise along with the outer surface shape of the pipe fitting 5. At this time, the second spring 361 is stretched. Then, through the elastic force of the second spring 361, the two upper rubber wheels 35 press down on the surface of the pipe fitting 5, and cooperate with the two lower rubber wheels 35 to clamp one end surface of the pipe fitting 5, and this method can clamp pipe fittings 5 with various different diameters. Embodiment 2:

[0039] On the basis of Embodiment 1, in order to further process the welded pipe fitting 5, a grinding assembly 4 can be arranged between the two second clamping assemblies 3.

[0040] Reference Figures 1-2 As shown in the figure, the grinding assembly 4 includes second fixed seats 45 symmetrically fixed on the surface of the workbench 1. A second screw 41 is rotatably arranged between the two second fixed seats 45. The outer side surface of one second fixed seat 45 is also fixedly provided with a first motor 6 to drive the rotation of the second screw 41 through the first motor 6.

[0041] Reference Figures 1-2 As shown in the figure, the surface of the second screw 41 is threaded with a sliding seat 42. The sliding seat 42 slides on the surface of the workbench 1. A third motor 43 is fixedly installed on the outer side surface of the sliding seat 42. A grinding wheel 44 is fixedly arranged on the surface of the output shaft of the third motor 43.

[0042] Further, after the pipe fitting 5 is welded, the rotation of the second screw 41 drives the movement of the sliding seat 42 to make the grinding wheel 44 approach the welding position. Then, cooperate with the second motor 22 to drive the rotation of the pipe fitting 5 to make the grinding wheel 44 grind the welding position of the pipe fitting 5, reducing the subsequent processing procedures of the pipe fitting 5 and improving the processing efficiency of the welding of the pipe fitting 5.
