Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a welding positioning device for automobile production. Background Art

[0002] For the welding of small automotive parts, in order to improve welding efficiency, existing processing equipment generally fixes the welding equipment above the transmission line to reduce the trouble of loading and unloading the parts to be welded onto the welding equipment, so that small automotive parts can be welded more conveniently and quickly. However, during the welding process, auxiliary positioning tooling is required to lift the parts on the transmission line to prevent the movement of the transmission line from interfering with the welding. In existing devices, the clamping device is generally driven upward by a cylinder to separate the parts to be welded from the transmission line. However, the acceleration of the cylinder-driven clamping device is large, which makes the speed of the clamping device uneven during the upward and downward movement. This makes it easy for the parts to be welded to have relative displacement with the clamping device during the upward and downward movement. In severe cases, the parts to be welded may fall and damage the product transportation line. Utility Model Content

[0003] The purpose of the utility model is to provide a welding positioning device for automobile production, to provide a positioning tool that can drive the clamping equipment to move up and down slowly and uniformly, to ensure the stability of the clamped parts during the movement, so that the welding equipment on the transport line can smoothly perform welding operations.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The top end of the frame is provided with a conveying member, and the side mounting plate is provided with two groups and is symmetrically mounted at the middle position of the upper end of the frame.

[0008] Preferably, a driven gear is fixedly mounted on the upper connecting rod, the driven gear is engaged with the driving gear, and a transmission member is provided between the driving gear and the lower connecting rod.

[0009] Preferably, an upper half gear is fixedly mounted on the upper connecting rod, a lower half gear is fixedly mounted on the lower connecting rod, the tooth portion of the limit gear is engaged with the tooth plate, the tooth portions of the upper half gear and the lower half gear are capable of engaging with the limit gear, and the tooth portions of the upper half gear and the lower half gear are staggered and engaged with the limit gear.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1.

[0014] 2. In actual use, the present invention can control the actual lifting height of the parts being processed by adjusting the number of adjusting teeth embedded in the side embedded groove of the incomplete gear.

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A welding positioning device for automobile production includes a side mounting plate 1 and a frame 5, and a conveying member 2 is provided at the upper end of the frame 5. The device is characterized in that: the side mounting plate 1 is provided with two groups and is symmetrically installed at the middle position of the upper end of the frame 5, and the conveying member 2 is located between the symmetrically arranged side mounting plates 1. A movable block 7 is slidably connected to the side mounting plate 1, and a cylinder 8 is fixedly installed on the upper end of the movable block 7. A tooth plate 9 is fixedly installed on the side of the movable block 7 away from the conveying member 2, and an incomplete gear 10 is rotatably installed on the side of the side mounting plate 1 away from the conveying member 2. A limiting gear 21 is rotatably provided below the side mounting plate 1, and the limiting gear 21 can engage with the tooth plate 9. A transmission assembly is provided between the limiting gear 21 and the incomplete gear 10, and the transmission assembly can drive the movable block 7 to move up at a uniform speed, stay for a certain period of time, and then move down at a uniform speed.

[0026] Among them, the transmission assembly includes an upper mounting frame 12 and a lower mounting frame 16. The upper mounting frame 12 is fixedly mounted on the side mounting plate 1. The lower end of the upper mounting frame 12 is rotatably mounted with a driving gear 15. The intermediate gear 11 is fixedly mounted with an incomplete gear 10. The tooth portion of the incomplete gear 10 is engaged with the driving gear 15.

[0027] The lower mounting frame 16 is fixedly mounted on the side mounting plate 1 , an upper connecting rod 17 is rotatably mounted on the lower mounting frame 16 , a lower connecting rod 18 is rotatably mounted below the upper connecting rod 17 , and a limiting gear 21 is rotatably mounted on the lower mounting frame 16 .

[0028] A driven gear 13 is fixedly mounted on the upper connecting rod 17 , and the driven gear 13 is engaged with the driving gear 15 . A transmission member 14 is provided between the driving gear 15 and the lower connecting rod 18 .

[0029] Among them, the upper half-width gear 19 is fixedly installed on the upper connecting rod 17, and the lower half-width gear 20 is fixedly installed on the lower connecting rod 18. The tooth part of the limit gear 21 is engaged with the gear plate 9, and the tooth parts of the upper half-width gear 19 and the lower half-width gear 20 can be engaged with the limit gear 21. The tooth parts of the upper half-width gear 19 and the lower half-width gear 20 are staggered and engaged with the limit gear 21.

[0030] A support frame 3 is fixedly mounted on the upper surface of the side mounting plate 1 , and a welding device is fixedly mounted on the upper end of the support frame 3 , and the welding head of the welding device can move horizontally.

[0031] The outer edge of the incomplete gear 10 is evenly provided with multiple groups of side embedded grooves 6 , and the side embedded grooves 6 are embedded with adjustment teeth 4 , which can mesh with the driving gear 15 .

[0032] In the present invention, the parts are moved to the support frame 3 through the conveying member 2. When the parts move to the middle position of the cylinder 8, the cylinders 8 are close to each other to clamp the parts to be welded. The motor built into the side mounting plate 1 drives the incomplete gear 10 to rotate. After the cylinder 8 clamps the parts to be welded, the adjustment teeth 4 on the incomplete gear 10 begin to mesh with the driving gear 15. The driving gear 15 rotates and drives the upper connecting rod 17 to rotate in the opposite direction through the driven gear 13 meshed therewith. In addition, the driving gear 15 drives the lower connecting rod 18 to rotate forward through the transmission member 14. The upper connecting rod 17 rotates to drive the upper half-width gear 19 to rotate, and the upper half-width gear 19 rotates to drive the limit gear The wheel 21 rotates counterclockwise, so that the limiting gear 21 interacts with the tooth plate 9 to drive the movable block 7 to move up and close to the upper mounting plate 4. After moving to the highest point, the meshing effect between the adjusting teeth 4 of the incomplete gear 10 and the driving gear 15 disappears. After the upward welding is completed, the adjusting teeth 4 of the incomplete gear 10 are re-engaged with the driving gear 15. At this time, the teeth part of the lower half gear 20 begins to mesh with the limiting gear 21, thereby driving the limiting gear 21 to rotate clockwise, thereby driving the movable block 7 to move downward. The movable block 7 moves downward, thereby driving the parts between the cylinder 8 to move downward, and the cylinder 8 contracts so that the welded parts fall back onto the conveyor 2. In the utility model, the parts are placed on the conveying member 2, and the parts are moved by the conveying member 2. After the parts are clamped by the cylinder 8, the movable block 7 automatically moves up and approaches the welding equipment. After the welding is completed, the movable block 7 automatically moves down and places the parts back on the conveying member 2, thereby automatically positioning the parts during the automatic transmission process and automatically unloading and continuing to transport the parts after the welding is completed. The positioning device simplifies the positioning process of parts during welding and avoids the trouble of manual assistance.

[0033] The present invention can realize that after the cylinder 8 clamps the parts to be welded, the parts clamped between the cylinder 8 are driven to move upward at a uniform speed through the interaction of the limit gear 21 and the tooth plate 9. After the parts are positioned and stay in the upward position for a specified time, the clamped parts are automatically driven to move downward at a uniform speed, thereby eliminating the acceleration of the parts during the up and down movement, ensuring the stability of the parts during the movement, avoiding the parts from shifting and falling during the lifting and lowering process, and avoiding the parts from falling and damaging the transportation line. In actual use, the actual lifting height of the parts during processing can be controlled by adjusting the number of adjusting teeth 4 embedded in the side embedded groove 6 in the incomplete gear 10. For smaller parts, a higher lifting height may be required in order to be as close to the welding equipment as possible. The more adjusting teeth 4 embedded in the side embedded groove 6, the greater the upward movement height of the parts. For larger parts, the larger the part volume, the fewer the number of adjusting gears embedded in the side embedded groove 6, and the lower the lifting height of the parts, which reserves more welding time for the parts accordingly.
