Description

Technical Field

[0001] The invention belongs to the technical field of weld grinding, and in particular relates to an automatic end face weld grinding robot. Background Art

[0002] Nowadays, in order to obtain the required metal parts, some metal parts are sometimes assembled and welded together to form the required parts. At the same time, welding has the advantages of good connection performance, large individual rigidity, strong process adaptability, material saving, good mechanical properties, etc., making it suitable for the connection of most metal parts at the same time. At the same time, there will be a weld at the connection of metal parts after welding, and the weld will be ground by a grinding device. Grinding the weld can improve the surface finish, increase the strength of the weld joint, improve the welding quality and facilitate subsequent processing.

[0003] However, in the process of grinding the weld, the traditional method is generally to grind and polish the weld surface with a grinding disc or a grinding and polishing belt. Since the grinding disc itself cannot be bent, the contact area with the weld is small when grinding and polishing the arc surface, which makes it inconvenient to grind and polish the weld. At the same time, it is difficult to make the weld unevenly ground, thus affecting the quality of the weld. The grinding and polishing belt is easy to deviate or even fall off during use, which is inconvenient to use. At the same time, a certain amount of dust will be generated during the grinding and polishing process, which will affect the human body and surrounding equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the process of grinding the weld, the traditional method is generally to grind and polish the weld surface by a grinding disc or a grinding-polishing belt.

[0011] As a further description of the above technical solution: The limit frames are arranged in two mirror images through the midpoint of the first pressure wheel. The limit frame is rotatably connected to the second pressure wheel through a through hole opened at one end of the limit frame. One end of the limit frame is fixedly connected to the mounting frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a driving assembly and an adjusting assembly are provided. When it is necessary to grind and polish the weld, the mechanical arm drives the mounting rod and the connecting frame to move, thereby driving the grinding and polishing belt to move to the top of the weld and make the grinding and polishing belt contact the weld. Then, the starting motor drives the driving wheel to rotate, thereby driving the grinding and polishing belt to move and driving the driven wheel to rotate. At the same time, since the grinding and polishing belt is in contact with the weld, the pressure plate is forced to move when the grinding and polishing belt is in contact with the weld, thereby driving the sliding rod to move through the pressure plate and compressing the second spring, thereby pushing the sliding rod and the pressure plate to squeeze the grinding and polishing belt through the reaction force of the second spring, thereby squeezing the grinding and polishing belt through the sliding rod and the pressure plate, so that the grinding and polishing belt can be in close contact with the weld. At the same time, when grinding and polishing the weld on the arc end face, the welding seam is in an arc shape, so that the grinding and polishing belt bends inward, thereby causing the grinding and polishing belts at other parts to move to a certain extent toward the bending part. The driven wheel is thereby subjected to a certain degree of extrusion, and the support frame is forced to move through the connecting columns on both sides of the driven wheel, thereby compressing the first spring on the bottom surface of the support frame and maintaining the stability of the support frame through the reaction force of the first spring, so that the driven wheel is in close contact with the grinding and polishing belt through the first spring, thereby preventing the grinding and polishing belt from loosening. Through this design, the welds on end faces of different shapes can be effectively ground, so that it can not only grind welds on planes but also welds on end face surfaces with a certain curvature, thereby improving the practicability of the grinding device and making it convenient for staff to operate through a robotic arm, thereby reducing the difficulty of use. At the same time, the pressure plate and the driven wheel are pressurized by the first and second springs to make them in close contact with the grinding and polishing belt, and the grinding and polishing belt is in close contact with the weld through the pressure plate, so that the weld can be evenly ground and polished by the grinding and polishing belt, thereby ensuring the grinding and polishing quality of the weld.

[0016] 2. In the present invention, by setting a limiting frame, during the process of grinding and polishing the weld, the driving wheel is driven to rotate by the motor and the grinding and polishing belt is driven to rotate on the surfaces of the driving wheel and the driven wheel. At the same time, since the limiting frame is installed on both sides of the mounting frame and the grinding and polishing belt is located between the limiting frames, the limiting frames block the two sides of the grinding and polishing belt to prevent it from sliding to both sides, and the second pressure wheel blocks the grinding and polishing belt to prevent it from separating from the driving wheel. At the same time, the slider is driven by the third spring and the first pressure wheel is driven by the slider to move, so that the grinding and polishing belt is squeezed by the first pressure wheel so that it can better fit with the driving wheel. When grinding and polishing the arc weld, due to the movement of the driven wheel The grinding and polishing belt on one side of the first pressure wheel moves to a certain extent and separates from the first pressure wheel to a certain extent, so that the third spring pulls the slider and the first pressure wheel to move so that the first pressure wheel contacts the grinding and polishing belt again, thereby always maintaining the contact between the first pressure wheel and the grinding and polishing belt. Through this design, the grinding and polishing belt is effectively limited, and it can be prevented from sliding to both sides and separating from the driving wheel during the grinding and polishing process, thereby affecting the grinding and polishing of the weld. At the same time, the grinding and polishing belt can be squeezed by the first pressure wheel and the second pressure wheel, so that the grinding and polishing belt can always maintain close contact with the driving wheel to avoid looseness, thereby ensuring the stability of the grinding and polishing belt when grinding and polishing the weld.

[0017] 3. In the present invention, a protective component is provided. During the process of grinding and polishing the weld with the grinding and polishing belt, the vacuum cleaner is started and the suction force generated by the vacuum cleaner is transmitted to the outer shell through the second suction pipe and the connecting cover. Thus, the dust generated by the grinding and polishing belt on the weld in the outer shell is sucked into the vacuum cleaner through the connecting cover and the second suction pipe through the suction force generated by the vacuum cleaner, and is transported to the dust collecting box through the first suction pipe. At the same time, when the arc-shaped end face weld is ground and polished, the baffle cloth contacts the arc surface. At the same time, since the baffle cloth has a certain ductility, it can produce a certain deformation when it contacts the arc surface so that it fits the arc surface. Through this design, the dust generated during the grinding and polishing of the weld is effectively collected, so as to prevent it from being scattered into the air and affecting the human body or surrounding equipment, thereby protecting the health of workers and equipment, avoiding harm to the health of workers, and reducing the damage to equipment to avoid equipment damage.

[0032] The specific embodiment is as follows: during the process of grinding and polishing the weld, the motor 53 drives the driving wheel 54 to rotate and drives the grinding and polishing belt 56 to rotate on the surfaces of the driving wheel 54 and the driven wheel 51. At the same time, since the limit frames 71 are installed on both sides of the mounting frame 63 and the grinding and polishing belt 56 is located between the limit frames 71, the limit frames 71 block the grinding and polishing belt 56 on both sides to prevent it from sliding to both sides.

[0033] The protective component 4 includes a shell 45, the top of which is fixedly connected to the bottom end of the connecting frame 3, a connecting cover 43 is fixedly connected to the top surface of the shell 45, and the connecting cover 43 is communicated with its inner cavity through a through groove opened on the top surface of the shell 45, a second suction pipe 44 is fixedly connected to one side of the connecting cover 43, and a dust collector 42 is fixedly connected to the other end of the second suction pipe 44, one side of the dust collector 42 is fixedly connected to the connecting frame 3, one end of the dust collector 42 is fixedly connected to the first suction pipe 41, and a dust collecting box is provided at the other end of the first suction pipe 41, a fixing block 46 is fixedly connected to the inner wall of the shell 45, and one side of the fixing block 46 is fixedly connected to the mounting frame 63, a fixing seat 47 is provided in the shell 45, and the bottom end of the fixing seat 47 is fixedly connected to the outer wall of the motor 53, openings are provided on both sides of the shell 45 and blocking cloth 48 is provided at the opening, and the blocking cloth 48 has a certain ductility.

[0034] The specific implementation example is as follows: during the process of grinding and polishing the weld with the grinding and polishing belt 56, the vacuum cleaner 42 is started and the suction force generated by it is transmitted to the outer shell 45 through the second suction pipe 44 and the connecting cover 43, so that the dust generated by the grinding and polishing belt 56 on the weld in the outer shell 45 is sucked into the vacuum cleaner 42 through the connecting cover 43 and the second suction pipe 44 through the suction force generated by the vacuum cleaner 42, and is transported to the dust collecting box through the first suction pipe 41. At the same time, when the arc-shaped end face weld is ground and polished, the blocking cloth 48 contacts the arc surface and, because the blocking cloth 48 has a certain ductility, it can produce a certain deformation when it contacts the arc surface so that it fits the arc surface.

[0035] Working principle: When the weld needs to be polished, the mechanical arm 1 drives the mounting rod 2 and the connecting frame 3 to move, thereby driving the polishing belt 56 to move to the top of the weld and make the polishing belt 56 contact the weld, thereby driving the driving wheel 54 to rotate by starting the motor 53, thereby driving the polishing belt 56 to move and driving the driven wheel 51 to rotate, and at the same time, since the polishing belt 56 is in contact with the weld, the pressure plate 68 is forced to move when the polishing belt 56 is in contact with the weld, thereby driving the slide bar 67 to move and compress the second spring 65 through the pressure plate 68, thereby pushing the slide bar 67 and the pressure plate 68 to squeeze the polishing belt 56 through the reaction force of the second spring 65, thereby squeezing the polishing belt 56 through the slide bar 67 and the pressure plate 68. The polishing belt 56 can be in close contact with the weld. At the same time, when the weld on the arc end face is polished, the polishing belt 56 bends inward due to the arc shape of the weld, so that the polishing belt 56 in other parts moves toward the bending part to a certain extent, so that the driven wheel 51 is squeezed to a certain extent, and the support frame 61 is forced to move through the connecting columns 55 on both sides of the driven wheel 51, so that the first spring 62 on the bottom surface of the support frame 61 is compressed and the support frame 61 is kept stable through the reaction force of the first spring 62, so that the driven wheel 51 is in close contact with the polishing belt 56 through the first spring 62, thereby preventing the polishing belt 56 from loosening, and in the process of polishing the weld, the driving wheel 54 is driven by the motor 53 to rotate and drive the polishing belt 56 The polishing belt 56 rotates on the surfaces of the driving wheel 54 and the driven wheel 51. At the same time, since the limiting frames 71 are installed on both sides of the mounting frame 63 and the polishing belt 56 is located between the limiting frames 71, the limiting frames 71 block the two sides of the polishing belt 56 to prevent it from sliding to both sides. At the same time, the second pressure wheel 77 blocks the polishing belt 56 to prevent it from separating from the driving wheel 54. At the same time, the third spring 76 drives the slider 73 and the slider 73 drives the first pressure wheel 75 to move, so that the polishing belt 56 is squeezed by the first pressure wheel 75 so that it can better fit with the driving wheel 54. When polishing the arc weld, the movement of the driven wheel 51 causes the polishing belt 56 on one side of the first pressure wheel 75 to move to a certain extent. The first pressing wheel 75 is separated to a certain extent, so that the slider 73 and the first pressing wheel 75 are pulled to move by the third spring 76 so that the first pressing wheel 75 is in contact with the grinding and polishing belt 56 again, so as to always keep the first pressing wheel 75 in contact with the grinding and polishing belt 56. At the same time, in the process of grinding and polishing the weld by the grinding and polishing belt 56, the suction force generated by the vacuum cleaner 42 is started and transmitted to the housing 45 through the second suction pipe 44 and the connecting cover 43. Thus, the dust generated by the grinding of the weld by the grinding and polishing belt 56 in the housing 45 is sucked into the vacuum cleaner 42 through the connecting cover 43 and the second suction pipe 44 by the suction force generated by the vacuum cleaner 42, and is transported to the dust collecting box through the first suction pipe 41. At the same time, when grinding and polishing the arc end face weld,The blocking cloth 48 is in contact with the curved surface and, because the blocking cloth 48 has a certain degree of ductility, it can produce a certain degree of deformation when in contact with the curved surface so that it fits the curved surface.
