Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to a pin welding auxiliary device. Background Technology

[0002] A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. Before being put into use, pins need to be welded by skilled workers.

[0003] When welding, the pin needs to be fixed by a fixing device to facilitate welding. The existing welding is generally fixed manually. This fixing method is not only unstable and prone to displacement, but also slow and cannot meet the needs of production. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a pin welding auxiliary device, which overcomes the shortcomings of the prior art and effectively solves the problems that the manual fixing in the prior art is not only not stable enough and prone to displacement, but also slow and cannot meet the needs of production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pin welding auxiliary device includes a base plate, a rotating rod rotatably connected to the top of the base plate, a turntable fixed to the top of the rotating rod, a fixed tube inserted into the top of the turntable, and support plates evenly distributed around the outer wall of the fixed tube. A fixed frame is fixed to one end of the top of the base plate, and lead screws are rotatably connected to the inner walls of both ends of the fixed frame. A support mechanism is screwed to the wall of the lead screw, and the support mechanism includes a first T-block, a push rod motor fixed to one end of the first T-block, a second T-block fixed to one end of the push rod motor, and a clamping ring inserted and fixed to one end of the second T-block.

[0007] The second servo motor drives the lead screw to rotate, which in turn moves the support mechanism so that its height matches the length of the pin to be welded. The lower half of the pin is inserted and fixed in the fixed tube through the corresponding fixing tube and clamping ring, and the upper half of the pin is inserted downward along the top of the clamping ring so that the bottom end of the upper half of the pin abuts against the top end of the lower half of the pin. After welding, the first servo motor drives the rotating rod to rotate through meshing gears. The rotating rod drives the turntable to rotate, causing the unfinished pin to rotate, thus completing the final welding operation.

[0008] Preferably, a first servo motor is installed on the top of the base plate, and the output shaft of the first servo motor and the rod wall of the rotating rod are both fitted with meshing gears.

[0009] The first servo motor drives the rotating rod to rotate through meshing gears.

[0010] Preferably, a groove is provided at the top center of the turntable, and the groove forms an interference fit with the fixing tube.

[0011] The fixing tube is inserted into the groove, which fixes the fixing tube to the top of the turntable, making it easy to replace fixing tubes of different diameters.

[0012] Preferably, a second servo motor is mounted on the top of the fixing frame, and the output shaft of the second servo motor is connected and fixed to the top of the lead screw.

[0013] The second servo motor drives the lead screw to rotate, adjusting the height of the support mechanism to make it suitable for welding pins of different lengths.

[0014] Preferably, the top of the first T-block has a screw hole adapted to the lead screw, and the first T-block and the fixing frame form a sliding fit.

[0015] The rotating lead screw drives the first T-block, which is screwed in, to move along the fixed frame.

[0016] Preferably, guide rods are fixed at both ends of the outer wall of one side of the second T-block, and the guide rods are in a plug-in movable fit with the first T-block.

[0017] The connection stability between the second T-block and the first T-block is improved by sliding the guide rod along the first T-block.

[0018] The beneficial effects of this utility model are as follows:

[0019] By adjusting the height of the support mechanism to match the length of the welded pin, and replacing the fixing tube and clamp corresponding to the pin, the lower half of the pin is inserted and fixed in the fixing tube, and the upper half of the pin is inserted downward along the top of the clamp, so that the bottom end of the upper half of the pin abuts against the top end of the lower half of the pin. After welding, the turntable is rotated to rotate the unfinished pin, thus completing the final welding operation. This effectively solves the problems of the existing technology, where manual fixing is not only unstable and prone to displacement, but also slow and cannot meet production needs.

[0026] Reference Figure 1-3 A pin welding auxiliary device includes a base plate 1, a rotating rod 2 rotatably connected to the top of the base plate 1, a turntable 4 fixed to the top of the rotating rod 2, a fixed tube 5 inserted into the top of the turntable 4, support plates 6 evenly distributed around the outer wall of the fixed tube 5, a fixed frame 7 fixed to one end of the top of the base plate 1, lead screws 8 rotatably connected to the inner walls of both ends of the fixed frame 7, a support mechanism 10 screwed to the wall of the lead screw 8, and the support mechanism 10 including a first T-block 11, a push rod motor 12 fixed to one end of the first T-block 11, a second T-block 14 fixed to one end of the push rod motor 12, and a clamping ring 15 inserted and fixed to one end of the second T-block 14.

[0027] A first servo motor 3 is installed on the top of the base plate 1. The output shaft of the first servo motor 3 and the rod wall of the rotating rod 2 are both fitted with meshing gears. The first servo motor 3 drives the rotating rod 2 to rotate through the meshing gears. A groove is opened at the center of the top of the turntable 4. The groove and the fixed tube 5 form an interference fit. The fixed tube 5 is inserted into the groove to fix the fixed tube 5 on the top of the turntable 4, which facilitates the replacement of fixed tubes 5 of different diameters. A second servo motor 9 is installed on the top of the fixing frame 7. The output shaft of the second servo motor 9 is connected and fixed to the top of the lead screw 8. The second servo motor 9 drives the lead screw 8 to rotate, which adjusts the height of the support mechanism 10 to make it suitable for welding pins of different lengths.

[0028] The top of the first T-block 11 is provided with a screw hole that matches the lead screw 8. The first T-block 11 and the fixed frame 7 form a sliding fit. The rotating lead screw 8 drives the screwed first T-block 11 to move along the fixed frame 7. Guide rods 13 are fixed at both ends of the outer wall of one side of the second T-block 14. The guide rods 13 and the first T-block 11 form a plug-in movable fit. The second T-block 14 and the first T-block 11 are plugged in and slid along the first T-block 11 by the guide rods 13, thereby improving the connection stability between the second T-block 14 and the first T-block 11.

[0029] Working principle:

[0030] During operation, the second servo motor 9 drives the lead screw 8 to rotate, which in turn moves the support mechanism 10 to match the height of the support mechanism 10 with the length of the welded pin. By replacing the fixing tube 5 and clamping ring 15 corresponding to the pin, the lower half of the pin is inserted and fixed in the fixing tube 5, and the upper half of the pin is inserted downward along the top of the clamping ring 15 so that the bottom end of the upper half of the pin abuts against the top end of the lower half of the pin. After welding, the first servo motor 3 drives the rotating rod 2 to rotate through meshing gears. The rotating rod 2 drives the turntable 4 to rotate, causing the unfinished pin to rotate, thus completing the final welding operation.
