Description

Industrial robot welding workbench

Technical Field

The invention relates to the technical field of machine welding, and in particular to an industrial robot welding workbench.

Background technique

Welding, also known as fusion or melting, is a technology that combines metals by heating, high temperature or high pressure. With the advancement of technology, the welding method has changed from manual welding to welding using industrial robots. The industrial robot welding process mainly includes a manipulator for welding and a workbench for placing welded parts. With the pursuit of welding quality and efficiency, the requirements for welding workbenches are getting higher and higher.

However, the existing industrial robot welding workbench still has the following defects:

1. As robot welding has the characteristics of fast welding and continuous and efficient welding, the traditional welding workbench cannot achieve continuous and efficient transportation of welded parts, and after the welding is completed and tested, it is impossible to classify and output qualified welded parts, which affects the continuous welding and reduces the welding efficiency;

2. In the continuous welding process, since the welding manipulator is uniformly programmed, it is necessary to accurately position the welded parts when conveying them to ensure the consistency of welding. Due to the difference in welding points, some welded parts need to be rotated relative to the manipulator during welding. The traditional welding workbench cannot accurately position the welded parts and selectively rotate them during welding, so its practicality needs to be further improved.

3. When the traditional welding workbench clamps the weldment, the clamping claws move synchronously. When facing weldments of different lengths and widths, it is easy for one end to be squeezed and clamped with the weldment, while the other side cannot contact the weldment, thereby reducing the clamping stability. At the same time, when facing cylindrical weldments, the point extrusion stability in four directions needs to be improved.

Summary of the invention

The purpose of the present invention is to solve the above-mentioned problems that the welded parts cannot be continuously and efficiently transported and outputted, the welding efficiency is reduced, the welded parts cannot be accurately positioned, selectively rotated during welding, and the clamping of the welded parts is not stable enough.

Therefore, after the welded parts are fixed on the fixed component, they are stably placed in the placement component on the rear side of the top of the rotating table, and then follow the intermittent clockwise rotation of the rotating table to the right side for welding. After welding, they arrive at the front side for inspection. If qualified, they are output from the front side, and if unqualified, they are output after rotating to the left side.

Furthermore, the left side and the front and rear sides of the outer sleeve are provided with notches, the width of which matches the diameter of the cylindrical table, so as to facilitate the transportation of the fixing components from the rear side and the output from the front and left sides.

The fixing component 8 is used to carry and fix the welded parts. Motor 9, the top of motor 9 is transmission connected with the rotating table 6, four groups of placement components 7 are arranged on the front and rear sides and the left and right sides of the top of the rotating table 6, the rear placement component 7 is used to place the fixed component 8 through the conveyor belt, the right placement component 7 is close to the machine welding arm 3 on the right side for welding, the front placement component 7 is used to output the fixed component 8 carrying qualified welded parts through the conveyor belt, and the left placement component 7 is used to output the fixed component 8 carrying unqualified welded parts through the conveyor belt.

After welding, they arrive at the front side for inspection. If qualified, they are output from the front side, and if unqualified, they are output after rotating to the left side.

The placement component 7 includes a placement groove 71. The front and rear sides and the left and right sides of the top of the rotating table 6 are provided with placement grooves 71. The top placement grooves 71 on the inner side of the rotating table 6 are fixedly connected with a mounting frame 72. A cylinder 73 is fixedly installed on the top of the mounting frame 72. A lifting plate 74 is fixedly installed on the top of the cylinder 73. The bottom end of a single lifting plate 74 is fixedly installed with two cylinders 73, and there are two lifting plates 74 in a single mounting frame 72, which are symmetrically distributed on the top of the mounting frame 72, and a groove for the lifting plates 74 to move up and down is provided on the top of the mounting frame 72. When the fixing component 8 is placed in the placement component 7, the lifting plates 74 are symmetrically distributed on both sides of the connecting rod 82, and the lifting plates 74 are located below the bottom end surface of the cylindrical table 81, so that the lifting plates 74 can lift the cylindrical table 81 upward when moving upward. The top of the lifting plate 74 is rotatably wrapped with a belt 75, and the top of the belt 75 extends above the top end surface of the lifting plate 74. Therefore, when the lifting plate 74 moves up to lift the cylindrical platform 81, the belt 75 can contact the bottom end of the cylindrical platform 81, thereby driving the cylindrical platform 81 to move. A motor 76 is fixedly installed in the middle of the bottom of the lifting plate 74, and the motor 76 is transmission-connected to the belt 75 for driving the belt 75 to rotate. A cylinder 2 is fixedly installed on the inner side of the mounting frame 72, and a clamping block 78 is fixedly installed on the inner side of the mounting frame 72 near one end of the cylinder 2 77. The clamping block 78 extends into the interior of the mounting frame 72, and the middle part of the connecting rod 82 is in the shape of a quadrangular prism. When the fixing component 8 is placed in the placing component 7, the middle part of the connecting rod 82 is limited and clamped on the inner side of the clamping block 78, thereby limiting the fixing component 8 and preventing it from rotating.

The fixing assembly 8 includes a cylindrical table 81, on which the cylindrical table 81 is placed at the top of the groove 71, a connecting rod 82 is fixedly installed in the center of the bottom end of the cylindrical table 81, a gear 83 is fixedly installed at the bottom end of the connecting rod 82, a cylindrical cover 84 is fixedly installed at the top end of the cylindrical table 81, a toothed disc 85 is connected to the inner limit rotation of the cylindrical cover 84 in the center of the top end of the cylindrical table 81, a worm 86 is connected to the outer limit rotation of the toothed disc 85 in the cylindrical cover 84, and the worm 86 and the toothed disc 85 are meshed with each other, so that the toothed disc 85 can be driven to rotate stably by rotating the worm 86, one end of the worm 86 is fixedly installed with an inner hexagonal screw head 87, and the inner hexagonal screw head 87 extends to the outside of the cylindrical cover 84, so that the worm 86 can be driven to rotate by the inner hexagonal screw head 87, a vortex spiral tooth 88 is fixedly installed on the top end of the toothed disc 85, and clamping assemblies 89 are evenly arranged around the top of the cylindrical cover 84, and the clamping assemblies 89 are used to extrude and fix the welded parts.

The clamping assembly 89 includes a slider 891, and the slider 891 is connected to the top of the cylindrical cover 84 in a limited sliding manner. The bottom end of the slider 891 is fixedly connected to a tooth 892, and the tooth 892 is meshed with the vortex spiral teeth 88 below. Therefore, when the toothed disk 85 drives the vortex spiral teeth 88 to rotate, it can drive the slider 891 to retract inward or expand outward at the same time. The top of the slider 891 is fixedly installed with a mounting block 893, and the internal limited sliding connection of the mounting block 893 is connected to a connecting plate 894. A spring 895 is fixedly connected between the end of the connecting plate 894 close to the center of the cylindrical cover 84 and the inner wall of the mounting block 893. The mounting block 893 is fixedly installed with limited The positioning block 896, the two sides of the connecting plate 894 are connected to the limiting block 896 by a transmission connection with an extrusion rod 897, and a wire groove 898 is provided inside the extrusion rod 897 to pass through it from top to bottom. An extrusion column 899 is fixedly installed on the end of the extrusion rod 897 away from the connecting plate 894. The extrusion rod 897 is symmetrically distributed on both sides of the mounting block 893, one side is hinged to the two sides of the connecting plate 894, and the other side extends to the side close to the center of the cylindrical cover 84 after passing through the limiting block 896. A column is fixedly set in the middle of the limiting block 896, and the column is located inside the wire groove 898. Therefore, when the extrusion column 899 is squeezed, it can drive the extrusion rod 897 to expand and deflect, and drive the connecting plate 894 to compress the spring 895.

A motor 2 10 is fixedly installed on the right side of the motor 9 at the top of the mounting table 2, and a gear 2 11 is fixedly connected to the top of the motor 2 10. The gear 2 11 is meshed with a gear 1 83 in the fixed component 8 on the right side. At the same time, whether the limit on the connecting rod 82 is released can selectively drive the fixed component 8 on the right side that is being welded to rotate.

The working principle of the present invention is:

Before welding, the weldment is clamped and fixed on the fixing assembly 8 by the clamping assembly 89, and the weldment is placed in the center of the top of the cylindrical cover 84. Then, the worm 86 is driven to rotate by the hexagonal screw head 87, and the worm 86 and the toothed disc 85 are meshed with each other to stably drive the toothed disc 85 to rotate, thereby driving the top fixed vortex spiral teeth 88 to rotate. During the rotation of the vortex spiral teeth 88, the bottom teeth 892 of the slider 891 are meshed with the vortex spiral teeth 88, so that the slider 891 can be simultaneously contracted inwardly, thereby driving the extrusion rod 897 and the extrusion column 899 to move inwardly and contact the outer surface of the weldment. When the extrusion column 899 contacts the outer surface of the weldment and continues to shrink, the sliding connection of the wire groove 898 on the extrusion rod 897 to the outer periphery of the column in the limit block 896 can make the extrusion rod 897 expand to both sides, and at the same time drive the connecting plate 894 to compress the spring 895, thereby elastically squeezing the end face of the weldment. Therefore, when the two opposite sides are in contact, the elastic extrusion can continue to shrink so that the other two opposite end faces can also be in contact and squeezed into position, thereby improving the clamping stability of weldments of different lengths and widths. At the same time, the expansion of the extrusion column 899 driven by the extrusion rod 897 can also better clamp and fix the cylindrical weldment.

After the welding part and the fixing component 8 are clamped and fixed, the fixing component 8 carrying the welding part is transported from the rear side of the rotating table 6 to the placement component 7 on the rear side. During the placement process, the middle part of the connecting rod 82 can extend into the inner side of the clamping block 78, thereby limiting the connecting rod 82, so that the fixing component 8 cannot rotate, and at the same time, the placement groove 71 is used to receive the cylindrical table 81. After the placement is completed, the rotating table 6 is driven by the motor 9 to rotate intermittently. During the rotation process, the design of the roller 5 on the outer sleeve plate 4 can better push the cylindrical table 81 to the middle and squeeze and contact with the edge of the placement groove 71, thereby further positioning the cylindrical table 81 to ensure the consistency of the position of the welding part carried by the fixing component 8 during the movement. As the rotating table 6 rotates intermittently, the fixing component 8 carrying the welding part moves. On the right side, the machine welding arm 3 is used to weld the welded parts. After welding is completed, it is rotated to the front side and the welding quality is tested. When the test is qualified, the lifting plate 74 is lifted upward by the action of the cylinder 73, and then the cylindrical table 81 is lifted, and the belt 75 is driven by the motor 76 to rotate, and the fixed component 8 is moved out to the conveyor belt for transportation, thereby completing the removal and transportation of qualified welded parts. Similarly, when the test is unqualified, the fixed component 8 follows the rotating table 6 to rotate to the left side, and then is moved out and transported. After rotating to the back side, the fixed component 8 carrying the welded parts is transported to the placement component 7 again, thereby realizing efficient transportation of welded parts and classified output of qualified and unqualified parts, which is conducive to the continuous and efficient operation of the robot welding line and improves the welding efficiency.

When the welding of the welded part requires itself to rotate relative to the machine welding arm 3, when the fixed assembly 8 carrying the welded part rotates to the right, the clamp block 78 is contracted by the action of the cylinder 2 77 to release the limit on the connecting rod 82, and then the right motor 2 10 is used to drive the rotation of the gear 2 11, and the mutual engagement of the gear 2 11 and the gear 1 83, so that the fixed assembly 8 at the right welding position can be rotated, thereby driving the welded part to rotate, which is beneficial to the welding, and then the clamp block 78 is used to limit the connecting rod 82 again by the action of the cylinder 2 77. During normal welding, the fixed assembly 8 cannot rotate due to the limit of the connecting rod 82 by the clamp block 78. When the gear 1 83 rotates to engage with the gear 2 11, it will drive the gear 2 11 and the motor 2 10 to idle, and the gear 1 83 itself will not rotate.

The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
