[0026] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides a bearing sleeve welding positioning device, comprising:

[0028] A workbench 1 is provided with a placement plate 2 on the top of the workbench 1. A rotating rod 3 is fixedly installed on the bottom of the placement plate 2. The bottom of the rotating rod 3 passes through the interior of the workbench 1. The rotating rod 3 and the interior of the workbench 1 are rotatably installed. Two groups of first snap rings 4 and two groups of second snap rings 5 ​​are provided on the top of the placement plate 2. Each group of first snap rings 4 is located on the left side of the second snap ring 5. A limiting block 6 is fixedly installed on the bottom of the first snap ring 4, and a stabilizing block 7 is fixedly installed on the bottom of the second snap ring 5.

[0029] Transmission assembly 8 and rotation assembly 9, the transmission assembly 8 is arranged on the top of the placement plate 2, the transmission assembly 8 is used to drive the limit block 6 and the stabilizing block 7 to move towards or away from each other at the same time, the rotation assembly 9 is fixedly installed inside the workbench 1, and the rotation assembly 9 is used to drive the rotating rod 3 to rotate.

[0030] Place the two sets of bearing sleeves to be welded on the top of the placement plate 2, and then place the bearing sleeves inside the first snap ring 4 and the second snap ring 5 respectively. Then, at this time, the transmission assembly 8 drives the limit block 6 and the stabilizing block 7 to move toward each other at the same time, so that the first snap ring 4 and the second snap ring 5 can fix the bearing sleeves to be welded. Finally, the two sets of bearing sleeves can be welded using a welding gun;

[0031] After the connection of the front sides of the two sets of bearing sleeves is welded, the rotating rod 3 and the placement plate 2 can be rotated by the rotating assembly 9. When the placement plate 2 rotates 180 degrees, the back of the bearing sleeve will rotate to the front. At this time, the connection of the back of the bearing sleeve can be welded by a welding gun.

[0032] After the back and front sides of the bearing sleeve are welded, the first snap ring 4 and the second snap ring 5 can be separated by the transmission assembly 8. Then the bearing sleeve can be turned ninety degrees so that the unwelded surface is rotated to the front side of the placement plate 2. At this time, the bearing sleeve is limited by the transmission assembly 8, and then the above method is repeated to weld the unwelded position.

[0033] The transmission assembly 8 includes a connecting rod 81, and forward and reverse screws 82 are provided on both sides of the top of the placement plate 2. The rear ends of the forward and reverse screws 82 pass through the back of the stabilizing block 7. The forward and reverse screws 82 are both threadedly installed with the limit block 6 and the stabilizing block 7. Both ends of the connecting rod 81 are rotatably installed through bevel gears and the forward and reverse screws 82.

[0034] Through the cooperation between the connecting rod 81 and the forward and reverse screws 82, the connecting rod 81 can be rotated to drive the forward and reverse screws 82 to rotate through the bevel gear. The rotation of the forward and reverse screws 82 drives the limit block 6 and the stabilizing block 7 to move towards or away from each other at the same time. When the limit block 6 and the stabilizing block 7 approach each other, they will drive the first retaining ring 4 and the second retaining ring 5 to limit the bearing sleeve, thereby welding it. When the limit block 6 and the stabilizing block 7 are away from each other, the welded bearing sleeve can be taken out.

[0035] A worm gear 83 is fixedly mounted on the surface of the connecting rod 81, a worm 84 is provided on the top of the placement plate 2, the worm gear 83 and the worm 84 are meshed, a motor 85 is fixedly mounted on the front end of the worm 84, and the bottom of the motor 85 is fixedly mounted to the top of the placement plate 2.

[0036] Through the mutual cooperation of the worm gear 83, the worm 84 and the motor 85, when the motor 85 is started, the worm 84 can be driven to rotate, the rotation of the worm 84 drives the worm gear 83 to rotate, the rotation of the worm gear 83 drives the connecting rod 81 to rotate, the rotation of the connecting rod 81 drives the forward and reverse screws 82 to rotate through the bevel gear, and the rotation of the forward and reverse screws 82 drives the limit block 6 and the stabilizing block 7 to move toward each other at the same time, so that the first retaining ring 4 and the second retaining ring 5 can be limited to prevent the first retaining ring 4 and the second retaining ring 5 from shaking when limiting the bearing sleeve.

[0037] Four groups of limiting grooves 10 are provided on the top of the placement plate 2 . The bottoms of the limiting blocks 6 and the stabilizing blocks 7 extend into the limiting grooves 10 . The limiting blocks 6 , the stabilizing blocks 7 and the limiting grooves 10 are slidably installed.

[0038] By setting the limiting groove 10, the limiting block 6 and the stabilizing block 7 can be limited to prevent the limiting block 6 and the stabilizing block 7 from becoming unstable during movement, thereby causing the first retaining ring 4 and the second retaining ring 5 to be unable to stably limit the bearing sleeve.

[0039] Bearing seats 11 are fixedly installed on both sides of the surface of the connecting rod 81, and the bottom of the bearing seat 11 and the two sides of the top of the placement plate 2 are fixedly installed.

[0040] By setting the bearing seat 11, the connecting rod 81 can be limited to prevent the connecting rod 81 from shaking during rotation, thereby causing the bevel gears at both ends of the connecting rod 81 to be unable to effectively drive the forward and reverse screws 82 to rotate, thereby making it impossible to limit the first retaining ring 4 and the second retaining ring 5.

[0041] The rotating assembly 9 includes an electric push rod 91 , a tooth plate 92 is fixedly mounted on the telescopic end of the electric push rod 91 , and a gear 93 is fixedly mounted on the bottom of the surface of the rotating rod 3 , and the gear 93 is meshed with the tooth plate 92 .

[0042] Through the mutual cooperation of the electric push rod 91, the tooth plate 92 and the gear 93, the electric push rod 91 can be started to drive the tooth plate 92 to move, and the movement of the tooth plate 92 drives the gear 93 to rotate. The rotation of the gear 93 drives the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the placement plate 2 to rotate, so that the unwelded position of the bearing sleeve can be rotated for welding.

[0043] A slider 94 is fixedly mounted on the bottom of the tooth plate 92 , and a slide groove 95 is provided on the bottom of the inner wall of the workbench 1 , and the slider 94 and the slide groove 95 are slidably mounted.

[0044] Through the cooperation between the slider 94 and the slide groove 95, the tooth plate 92 can be limited to prevent the tooth plate 92 from being separated from the gear 93 during movement, thereby causing the tooth plate 92 to be unable to always engage with the gear 93, thereby causing the tooth plate 92 to be unable to drive the gear 93 to rotate.

[0045] Reinforcement blocks 12 are fixedly installed on both sides of the top of the placement plate 2, and the front side of the reinforcement block 12 is rotatably installed through a bearing and the back side of the forward and reverse screw 82.

[0046] By setting the reinforcement block 12, the forward and reverse screws 82 can be limited to prevent the forward and reverse screws 82 from shaking during rotation, thereby causing the forward and reverse screws 82 to be unable to drive the limit block 6 and the stabilizing block 7 to move in a straight line during rotation.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
