Description

Technical Field

[0001] The utility model relates to the technical field of automobile component welding equipment, in particular to a robot welding tooling structure. Background Art

[0002] In the welding field, robots are often used instead of manual welding. During welding, a tooling structure is needed to place automobile parts on it for easy welding. Since waste chips will be discharged and splashed during welding, it is not conducive to the beauty of the environment and endangers the human respiratory tract. In addition, due to the special shape of automobile parts, the inclination of the welding surface will increase the difficulty of welding. The existing welding tooling structure cannot solve these problems. Therefore, we have introduced a robot welding tooling structure.

[0003] Patent number CN202221919029.6 is a Chinese utility model patent, which discloses a welding tool for an industrial robot, including a welding table, a clamping structure and a clamping structure; according to the outer dimensions of the welding workpiece, the clamping mechanism is placed in the corresponding hole, the lower end of the fixed cylinder is inserted into the hole, the limit plate contacts the upper end of the hole, the driving member drives the screw to rotate, the moving column moves on the screw and drives the driving column to move downward, the driving column contacts the inclined surface of the vertical block, and as the driving column moves downward, the L-shaped clamping block moves outward in the opening, and the spring structure stretches. At this time, the upper side surface of the L-shaped notch on the vertical block is in contact with the inner wall of the hole. The lower side of the L-shaped notch contacts the lower end of the hole, so that the fixing cylinder is engaged in the hole, and then the lifting assembly is used to drive the clamping plate to descend, and the structure to be welded is clamped to prevent movement during the welding process. The driving member drives the screw rod to reverse, and the fixing cylinder can be removed from the hole. The position of the clamping structure on the welding table can be adjusted as needed. However, the utility model has the following problems: first, it does not have the function of vacuuming and cleaning the waste chips generated during welding, which is not conducive to the beauty of the environment and threatens the human respiratory system. Secondly, it does not have the function of adjusting the height of the placement table. Most automotive parts are special-shaped parts, and the inclination of the welding surface will increase the difficulty of welding. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the prior art and to solve the technical problems that the existing welding tooling structure is unable to vacuum and clean waste chips, resulting in a poor workshop environment, and the special-shaped appearance of automobile parts increases the difficulty of welding by arranging a lead screw and a dust suction port, a clamping tooth and a woven bag, a sleeve foot and a fixed foot.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A robot welding tooling structure comprises a mounting table, wherein mechanical arm mounting positions are evenly distributed on the left and right sides and the front edge positions of the upper end of the mounting table, and a storage table is provided directly above the mounting table, and rectangular blocks are symmetrically provided on the rear side of the upper end of the mounting table, a lead screw is provided between the rectangular blocks, a connecting block is provided on the outer surface of the lead screw, a dust suction port is provided at the front end of the connecting block, fixed feet are movably connected to the right side positions of the front and rear ends of the storage table, and sleeve feet are symmetrically provided on the left side positions of the lower end of the storage table, and the mechanical arm mounting position is suitable for installing a welding mechanical arm.

[0007] As a preference, supporting feet are provided at the four corners of the lower end of the mounting platform, and lifting cylinders are symmetrically provided at the left side of the lower end of the mounting platform, and a dust suction device is provided at the rear side of the lower end of the mounting platform.

[0008] As a preference, the lower end of the fixed foot is fixedly connected to the mounting platform, a buffer pad is provided on the upper end surface of the sleeve foot, and the lower end of the buffer pad is connected to the piston rod of the lifting cylinder.

[0009] As a preference, a telescopic tube is provided at the upper end of the dust suction device, and the upper end of the telescopic tube passes through the mounting platform and is fixedly connected to the dust suction port.

[0010] As a preferred embodiment, latch teeth are evenly distributed on four side surfaces of the dust collecting device, and outer surfaces of the latch teeth are connected to a woven bag.

[0011] As a preference, the left end of the lead screw passes through the rectangular block on the left side to be fixedly connected to the motor, a cushion block is provided at the lower end of the motor, and the cushion block is located at the upper end of the mounting platform.

[0012] Beneficial effects of the utility model:

[0013] (1) In the utility model, a lead screw and a dust suction port are provided. When the motor is working, its output shaft drives the lead screw to rotate, and the lead screw converts the rotational motion into linear motion, so that the connecting block can drive the dust suction port to move left and right, and the dust suction port can move with the welding position, thereby optimizing the dust suction and cleaning effect.

[0014] (2) In the utility model, by providing latch teeth and a woven bag, the waste scraps sucked up by the dust suction structure are collected in the woven bag. Since the woven bag is woven together by plastic wire, gaps or holes will be formed when subjected to force. The woven bag can be fixed to the dust suction device through the latch teeth by hand, so that the waste scraps are collected in the woven bag through the dust suction device. When the waste scraps are full, the woven bag can be replaced, which makes cleaning the waste scraps more convenient.

[0015] (3) In the utility model, by providing a sleeve foot and a fixed foot, the lifting cylinder works to make its piston rod push the sleeve foot upward. Because a buffer pad is provided in the sleeve foot, the collision between the sleeve foot and the piston rod can be reduced. In addition, the stress-deformation property of the buffer pad enables the piston rod of the lifting cylinder to smoothly lift the left side of the storage table, thereby reducing the height difference of the welding surface caused by the irregular shape of the outer tube of the automobile parts, keeping the welding surface level as much as possible, and reducing the difficulty of welding.

[0016] In summary, the utility model has the advantages of simple structure and good dust collection and cleaning effect, and is particularly suitable for the technical field of automobile parts welding equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figures 1 to 5As shown, the utility model provides a robot welding tooling structure, including a mounting table 1, which is the main load-bearing structure of the welding tooling structure. Mechanical arm mounting positions 2 are evenly distributed on the left and right sides and the front edge of the upper end of the mounting table 1. A plurality of mechanical arm mounting positions 2 are set, so that the installation position of the welding mechanical arm 6 can be adjusted to obtain a better welding effect. A storage table 3 is provided directly above the mounting table 1. Automobile parts need to be placed centrally on the storage table 3 for welding. Rectangular blocks 4 are symmetrically provided at the rear side of the upper end of the mounting table 1 to provide installation positions for screw rods 41. Screw rods 41 are provided between the rectangular blocks 4. The screw rods 41 are composed of three parts: a screw rod, a nut, and a ball, and can convert rotational motion into linear motion. A connecting block 42 is provided on the outer surface of the screw rod 41. A dust suction port 5 is provided at the front end of the connecting block 42. When the motor 10 is working, the dust suction port 5 is provided. Under the use, the output shaft of the motor 10 rotates to drive the screw 41 to work, and the rotational motion is converted into linear motion, so that the connecting block 42 performs linear motion on the screw 41, so that the dust suction port 5 can move left and right. Therefore, the position of the dust suction port 5 is changed according to the different welding positions to optimize the dust suction and cleaning effect. The right side positions at the front and rear ends of the storage table 3 are movably connected to the fixed feet 31, so that the right side of the storage table 3 cannot be adjusted in height. The left side of the storage table 3 changes in height under the action of the lifting cylinder 8, thereby leveling the welding surface, reducing the height difference of the welding surface caused by the outer tube shape of the automobile parts, and reducing the difficulty of welding. The left side position of the lower end of the storage table 3 is symmetrically provided with sleeve feet 32 ​​front and back to limit the telescopic length of the piston rod of the lifting cylinder 8, and provide external protection for the buffer pad 33. The robot arm mounting position 2 is adapted to install the welding robot arm 6.

[0026] Further, if Figure 1 As shown, support feet 7 are provided at the four corners of the lower end of the mounting platform 1 to provide stable support for the mounting platform 1, increase the height of the mounting platform 1 from the ground, and provide installation space for the lifting cylinder 8 and the dust suction device 9. The lifting cylinder 8 is symmetrically provided at the left side of the lower end of the mounting platform 1 to provide power support for the height adjustment of the left side of the storage platform 3. The dust suction device 9 is provided on the rear side of the lower end of the mounting platform 1. The dust suction device 9 generates suction when it works, so that the waste chips generated by welding enter the woven bag 93 through the dust suction port 5 and the telescopic tube 91, thereby achieving the effect of dust suction and cleaning.

[0027] Further, if Figure 4 As shown, the lower end of the fixed foot 31 is fixedly connected to the mounting platform 1, and the upper end surface of the sleeve foot 32 is provided with a buffer pad 33. The lower end of the buffer pad 33 is connected to the piston rod of the lifting cylinder 8. The buffer pad 33 is supported by a silicone material to reduce the collision between the lifting cylinder 8 and the sleeve foot 32. When the lifting cylinder 8 lifts the storage platform 3 upward, the buffer pad 33 can balance the positional relationship between the lifting cylinder 8 and the storage platform 3, making the relationship between the two more stable.

[0028] Further, if Figure 3 As shown, a telescopic tube 91 is provided at the upper end of the dust suction device 9, and the upper end of the telescopic tube 91 passes through the mounting platform 1 and is fixedly connected to the dust suction port 5. The telescopic tube 91 is a corrugated tube, and its overall length changes under the action of force, thereby reducing the sense of restraint when the dust suction port 5 moves left and right.

[0029] Further, if Figure 5 As shown, the four side surfaces of the dust suction device 9 are evenly distributed with latch teeth 92, and the outer surfaces of the latch teeth 92 are connected to a woven bag 93. The waste scraps sucked by the dust suction structure 9 are gathered in the woven bag 93. Since the woven bag 93 is woven together with plastic wires, gaps or holes will be formed when subjected to force. The woven bag 93 can be fixed to the dust suction device 9 through the latch teeth 92 by hand, so that the waste scraps are collected in the woven bag 93 through the dust suction device 9. When the waste scraps are full, just replace the woven bag 93, and cleaning the waste scraps is more convenient.

[0030] Further, if Figure 1 As shown, the left end of the screw 41 passes through the rectangular block 4 on the left side and is fixedly connected to the motor 10, providing power support for the screw 41. A cushion block 101 is provided at the lower end of the motor 10, and the cushion block 101 is located at the upper end of the mounting platform 1. The cushion block 101 provides an installation position for the motor 10, increases the installation height of the motor 10, and thus balances the positional relationship between the motor 10 and the screw 41.

[0031] Working process: first, place the automobile parts on the storage table 3, and according to the situation of the welding surface of the automobile parts, operate the lifting cylinder 8 to adjust the height of the left side of the storage table 6, so as to level the welding surface as much as possible and reduce the difficulty of welding; further, the motor 10 works to make the screw 41 work, so as to adjust the position of the dust suction port 5 as close as possible to the welding position where the welding surface is about to be welded; further, when the welding robot arm 6 is welding, the dust suction device 9 works, so that the waste chips are collected from the dust suction port 5 and the telescopic tube 91 in the woven bag 93, so as to achieve the effect of dust suction and cleaning.

[0033] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
