[0030] Embodiment 1:

[0031] As Figures 1 to 6As shown in the figure, an adjustable welding fixture for the bucket arm components of an excavator includes a base 1, a mandrel 2, a positioning assembly 3, a sliding assembly 4, and a lifting assembly 5. Two groups of the positioning assembly 3 are symmetrically arranged in the short side direction of the base 1. Each group of the positioning assembly 3 includes a first mounting seat 31, a second mounting seat 32, a third mounting seat 33, a fourth mounting seat 34, and a fifth mounting seat 35 arranged in the long side direction of the base 1. The positioning assembly 3 is used to carry and position workpieces. The first mounting seat 31, the second mounting seat 32, the third mounting seat 33, the fourth mounting seat 34, and the fifth mounting seat 35 are freely adjustable in the long side direction of the base 1 through the sliding assembly 4. An lifting assembly 5 is arranged between the fourth mounting seat 34 and the fifth mounting seat 35 and the sliding assembly 4, and the lifting assembly 5 respectively adjusts the horizontal heights of the fourth mounting seat 34 and the fifth mounting seat 35 in the vertical direction.

[0032] It is worth mentioning here that a slidable and adjustable sliding assembly 4 is arranged below the positioning assembly 3, so that the first mounting seat 31, the second mounting seat 32, the third mounting seat 33, the fourth mounting seat 34, and the fifth mounting seat 35 can be freely adjusted in the long side direction of the base 1, and the position of the actual mounting hole of the workpiece can be adjusted in time to avoid interference during the workpiece loading and positioning, and the situation where workers use brute force, knocking and other methods to force the loading. It is convenient for workers to quickly disassemble and assemble, improving work efficiency. By setting the lifting assembly 5 to freely adjust the horizontal heights of the fourth mounting seat 34 and the fifth mounting seat 35 in the vertical direction, and cooperating with the sliding adjustment of the sliding assembly 4, the positioning assembly 3 can meet the loading and installation requirements of workpieces of multiple models at the same time, saving the cost of producing multiple sets of fixtures according to workpieces of different models.

[0033] As Figures 1 to 3 As shown in the figure, the sliding assembly 4 includes a slide plate 41, a T-shaped groove 42, a hexagon bolt 43, and a nut 44. The slide plate 41 is slidably arranged on the base 1. The first mounting seat 31, the second mounting seat 32, and the third mounting seat 33 are integrally arranged with the slide plate 41. The fourth mounting seat 34 and the fifth mounting seat 35 are separately arranged with the slide plate 41. Two groups of the T-shaped grooves 42 are symmetrically opened on the base 1. The bolts 43 are symmetrically penetrated through both sides of the slide plate 41, and the nuts of the bolts 43 are located in the T-shaped grooves 42. The nut 44 is installed on the bolt 43.

[0034] It should be noted here that the bolt 43 is an external hexagon bolt. The two opposite sides of the hexagonal nut are attached to the inner walls of both sides of the T-shaped groove 42, which is convenient for fixing the position of the bolt 43 in the short side direction of the base 1. At the same time, the T-shaped groove restricts the rotation of the bolt 43, which is convenient for locking the nut 44.

[0035] AsFigure 1 , 2 As shown in 2 , a sliding groove 45 is formed in the middle of the two sets of T-shaped grooves 42, and a slider 46 is downwardly extended from the sliding plate 41.

[0036] It should be noted here that the slider 46 slides in the sliding groove 45. By setting the sliding groove 45 and the slider 46, when the sliding component is installed, the preliminary positioning in the short side direction of the base can be completed simply and quickly, and during the process of fixing the locking nut 44 on the sliding plate 41, the sliding plate 41 can be prevented from rotating due to the friction of the nut 44, resulting in position deviation.

[0037] As Figure 1 , 2 As shown in 2 , U-shaped grooves 36 are formed at the tops of the first mounting seat 31, the second mounting seat 32, the third mounting seat 33, the fourth mounting seat 34, and the fifth mounting seat 35.

[0038] It should be noted here that when installing the workpiece, the mandrel 2 penetrates the mounting hole of the workpiece, and then both ends of the mandrel 2 are placed on the corresponding U-shaped grooves 36.

[0039] As Figure 1 , 3 As shown in Figure 1 and 4, the lifting component 5 is a scissor lift group 51.

[0040] It should be noted here that the scissor lift group 51 is composed of a plurality of connecting rods 511 which are sequentially and alternately hinged end to end from bottom to top. The top and bottom of the same side of the scissor lift group 51 are respectively hinged to the corresponding fourth mounting seat 34, fifth mounting seat 35, and the corresponding sliding plate 41. The other side of the top of the scissor lift group 51 is slidably arranged on the long groove 341 formed at the bottom of the corresponding fourth mounting seat 34 and fifth mounting seat 35. The other side of the bottom of the scissor lift group 51 is rotatably connected to one side of the lead screw slider 52. In the same scissor lift group 51, two sets of lead screw sliders 52 are provided, and the two sets of lead screw sliders 52 are respectively slidably arranged on two sets of lead screws 53. The lead screws 53 are rotatably arranged on the sliding plate 41, and one ends of the two sets of lead screws 53 are connected by a pulley group 54. One end of one set of lead screws 53 is connected to a driving member 55, and the driving member 55 is fixed to the corresponding sliding plate 41.

[0041] It should be further noted here that when the driving member 55 is started, the lead screw 53 is driven to rotate. The rotation of the lead screw 53 is transmitted to the other lead screw 53 through the pulley group 54. The two lead screws 53 rotate in the same direction, driving the lead screw slider 52 to slide, thereby changing the lifting of the scissor lift group 51 and adjusting the horizontal height of the fourth mounting seat 34 and the fifth mounting seat 35 in the vertical direction.

[0042] As Figure 1 , 6As shown in the figure, it further includes an adjusting component 6. The adjusting component 6 is installed on the third mounting seat 33, and this adjusting component 6 is used to eliminate the degrees of freedom of the workpiece in the short side direction of the base 1.

[0043] It is worth mentioning here that the adjusting component is installed on the third mounting seat, which prevents the adjusting component from falling during the welding of the workpiece and also avoids the problem that the adjusting component is easily lost due to its small size.

[0044] As Figure 6 shown in the figure, the adjusting component 6 includes an adjusting bolt 61 screwed on the third mounting seat 33. A round plate 62 is provided at the threading end of the adjusting bolt 61, and a rubber pad 63 is provided on the round plate 62.

[0045] It is worth mentioning here that the rubber pad on the adjusting component can protect the workpiece and prevent it from being damaged by the adjusting component during the process of the adjusting bolt 61 being tightened to push the workpiece, thus improving the product quality.

[0046] As Figure 6 shown in the figure, a handle 64 is provided at the nut end of the adjusting bolt 61.

[0047] It is worth mentioning here that the handle can achieve manual and rapid adjustment to lock or loosen the adjusting bolt 61 without borrowing additional locking tools, thus improving the work efficiency.

[0048] The working process is as follows:

[0049] When positioning and welding the workpiece, initially adjust the sliding component 4 according to the position of the mounting holes of the workpiece, then adjust the horizontal height of the lifting component 5. Penetrate the mandrel 2 through the mounting holes of the workpiece, and then place both ends of the mandrel 2 on the U-shaped grooves 36 at the corresponding positions. According to the situation after the workpiece is loaded, adjust the position of the sliding component 4 and the horizontal height of the lifting component 5. Lock the nut 44 to fix the position of the sliding component 4, and manually tighten the adjusting bolt 61 to eliminate the degrees of freedom of the workpiece in the short side direction of the base 1, and then carry out the welding work.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
