Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automated welding technology, and in particular relates to an automatic flipping laser welding fixture. Background Technology
[0002] Existing laser welding tilting fixtures have poor versatility, typically designed with a fixed width, resulting in limited applicability. Furthermore, existing fixtures use adjustable columns with adjustable bolts and lock nuts to adjust the height of the tilting tray. This adjustment method is only suitable for small-sized welding tilting fixtures; for larger fixtures, the increased mass of the adjustable columns, tray, and drive motor makes adjustment impossible. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a welding flipping fixture with a wide range of applicability for width clamping and the ability to automatically adjust the height of large-sized pallets.
[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an automatic flipping laser welding fixture, including a base, a flipping mechanism, a second linear slide rail and a second slider, wherein two second linear slide rails are horizontally fixedly installed on the right end of the base, and the second slider is slidably installed on the second linear slide rails;
[0005] The flipping mechanism consists of a bracket, a chain lifting mechanism, a first linear slide rail, a turntable, a first slider, a tray, a connecting rod, a counterweight, and a drive motor. The chain lifting mechanism is fixedly installed on the top of the bracket, two first linear slide rails are vertically fixedly installed on the inner side of the bracket, the first slider is slidably installed on the first linear slide rail, the two ends of the lifting chain of the chain lifting mechanism are fixedly connected to the first slider and the counterweight respectively, the turntable is rotatably installed on the first slider through a rotating shaft, and the tray is fixedly installed on the turntable.
[0006] The bracket of the flipping mechanism on the left is fixedly installed on the left side of the base, and the bracket of the flipping mechanism on the right is fixedly installed on the second slider. The two ends of the connecting rod are fixedly connected to the trays of the left and right flipping mechanisms respectively.
[0007] The drive motor is fixedly mounted on the first slider of the left-side flipping mechanism, and the output shaft of the drive motor is connected to the rotating shaft of the left-side flipping mechanism turntable.
[0008] Preferably, guide rods are fixedly installed on the left side of the base and on the second slider, and a guide sleeve is fixedly installed at the bottom of the counterweight, with the guide sleeve slidably fitted onto the guide rods.
[0009] Preferably, the first slider is screwed with a first clamping bolt for pressing and fixing it onto the first linear slide rail, and the second slider is screwed with a second clamping bolt for pressing and fixing it onto the second linear slide rail.
[0010] Preferably, the front and rear sides of the trays of the left and right flipping mechanisms are provided with slots, the connecting rod is slidably embedded in the slots, the slots are provided with threaded holes, and the connecting rod is provided with transverse elongated holes. The two ends of the connecting rod are locked and fixed to the tray by screws through the cooperation of the transverse elongated holes and the threaded holes.
[0011] Compared with existing technologies, the advantages of this utility model are: this fixture can automatically adjust the height of large-sized pallets, which is more convenient and safer than manual adjustment. Furthermore, the distance between the two flipping mechanism pallets is adjustable, meeting the needs of laser welding operations for products of various sizes. By setting a connecting rod, the shearing force on the product clamping fixture when the two pallets rotate can be reduced, further extending the service life of the fixture. Attached Figure Description
[0012] The present invention will be further described below with reference to the accompanying drawings.
[0013] Figure 1 This is the front view of this utility model.
[0014] Figure 2 This is a top view of the present invention. Detailed Implementation
[0015] The present invention will now be described in detail with reference to specific embodiments:
[0016] like Figure 1 and Figure 2 The automatic flipping laser welding fixture shown includes a base 1, a flipping mechanism, a second linear slide rail 7, and a second slider 71. The two second linear slide rails 7 are horizontally fixedly installed on the right end of the base 1, and the second slider 71 is slidably installed on the second linear slide rails 7.
[0017] The flipping mechanism consists of a bracket 2, a chain lifting mechanism 3, a first linear slide rail 31, a turntable 4, a first slider 40, a tray 41, a connecting rod 5, a counterweight 6, and a drive motor 8. The chain lifting mechanism 3 is fixedly installed on the top of the bracket 2. The two first linear slide rails 31 are vertically fixedly installed on the inner side of the bracket 2. The first slider 40 is slidably installed on the first linear slide rail 31. The two ends of the lifting chain of the chain lifting mechanism 3 are fixedly connected to the first slider 40 and the counterweight 6, respectively. The turntable 4 is rotatably installed on the first slider 40 through a rotating shaft. The tray 41 is fixedly installed on the turntable 4.
[0018] The bracket 2 of the flipping mechanism on the left is fixedly installed on the left side of the base 1, and the bracket 2 of the flipping mechanism on the right is fixedly installed on the second slider 71. The two ends of the connecting rod 5 are respectively fixedly connected to the trays 41 of the left and right flipping mechanisms.
[0019] The drive motor 8 is fixedly mounted on the first slider 40 of the left-side flipping mechanism, and the output shaft of the drive motor 8 is connected to the rotating shaft of the left-side flipping mechanism turntable 4.
[0020] Guide rods 62 are fixedly installed on the left side of the base 1 and on the second slider 71, respectively. A guide sleeve 61 is fixedly installed at the bottom of the counterweight 6. The guide sleeve 61 is slidably sleeved on the guide rod 62. Through the longitudinal guiding effect of the guide sleeve 61 and the guide rod 62 slidingly cooperating, the swaying problem of the counterweight 6 when moving up and down can be avoided, and the stability and safety of the counterweight 6 when moving up and down can be improved.
[0021] The first slider 40 is screwed with a first clamping bolt for pressing and fixing it onto the first linear slide rail 31. Tightening the first clamping bolt can restrict the first slider 40 from sliding up and down along the first linear slide rail 31. The second slider 71 is screwed with a second clamping bolt for pressing and fixing it onto the second linear slide rail 7. Tightening the second clamping bolt can restrict the second slider 71 from sliding left and right along the second linear slide rail 7, thereby improving the stability of the tooling during laser welding operations.
[0022] The left and right flipping mechanisms have slots on the front and back sides of the tray 41. The connecting rod 5 is slidably embedded in the slot. The slot has a threaded hole, and the connecting rod 5 has a horizontal elongated hole. The connecting rod 5 is locked to the tray 41 by screws through the cooperation of the horizontal elongated hole and the threaded hole. The slot can restrict the degree of freedom of the connecting rod 5 in the vertical direction, which solves the problem that the screw is affected by the shear force in the vertical direction, thus affecting its service life.
[0023] The left and right flipping mechanisms adjust the height of the assembly of the first slider 40, turntable 4, first slider 40, tray 41, connecting rod 5 and drive motor 8 through the chain lifting mechanism 3. The counterweight 6 can reduce the load force of the chain lifting mechanism 3 during operation. When it is necessary to adjust the width between the two trays 41, first remove one section of the connecting rod 5 from one tray 41. The flipping mechanism on the right side slides left and right synchronously with the second slider 71. After the adjustment is completed, fix the removed end of the connecting rod 5 to the tray 41. Then fix the fixture adapted to the laser welding product on the two 41. The product to be welded is fixed on the fixture. Start the drive motor 8 to drive the turntable 4, tray 41, connecting rod 5, fixture and product to be welded to rotate synchronously.
