Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a highly compatible boom welding fixture. Background Technology

[0002] The boom in specialized equipment such as rock drilling rigs and anchoring rigs is a crucial load-bearing component, requiring high-quality welding. Currently, welding workstations enable efficient and high-quality boom welding operations. These workstations consist of a head-and-tail positioner in conjunction with other welding equipment. The head-and-tail positioner supports the boom and rotates it, while the welding equipment performs the welding.

[0003] However, due to the wide variety of specialized equipment products and different models, the boom specifications and forms are diverse. Not only do the booms vary in length, but the cross-sectional shape of the boom is also different, typically with pin holes on one end and different shapes on the other, such as rectangular or trapezoidal. Conventional head-and-tail positioners have difficulty quickly clamping different types and specifications of booms, resulting in low compatibility. Summary of the Invention

[0004] To address the low compatibility issue of conventional head-and-tail positioners, this invention provides a highly compatible boom welding fixture that can adapt to booms of different lengths. It also includes matching clamps designed for different booms, allowing for quick clamping and switching between booms of different specifications when the corresponding clamps are installed on the positioner.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A highly compatible boom welding fixture includes a base with a long slide rail, a head box positioner, a tail box positioner, and a lifting bracket. The head box positioner is fixedly mounted on one end of the base, and the tail box positioner is slidably mounted on the other end of the base, so as to facilitate adjustment of the distance between the head box positioner and the tail box positioner. The lifting bracket for supporting the boom is slidably mounted on the base between the head box positioner and the tail box positioner.

[0007] The head box positioner is slidably provided with two centering slides. The two centering slides can slide towards each other or away from each other at the same time. Each centering slide can be detachably provided with a clamp, which makes it convenient to use two clamps that are close to each other to clamp one end of the boom.

[0008] The tail box positioner is equipped with a lifting module, on which two centering slides are slidably arranged. Each of the two centering slides is detachably equipped with a clamp. The clamps on the centering slides cooperate to clamp the boom. The clamps are positioning clamping pins or positioning claws.

[0009] Furthermore, both the head box positioner and the tail box positioner are rotary positioners.

[0010] Furthermore, the head box positioner is equipped with a bidirectional lead screw module for driving the centering slide. The bidirectional lead screw module is arranged horizontally, and the centering slide is arranged on both sides of the bidirectional lead screw module, which facilitates the control of the centering slides moving closer or further apart.

[0011] Furthermore, the lifting module is a lead screw module structure, with the lifting module arranged vertically. The lifting module is equipped with a bidirectional lead screw module two for driving the centering slide two. The bidirectional lead screw module two is arranged horizontally, and the centering slide two is provided on both sides of the bidirectional lead screw module two, which facilitates the control of the centering slide two to move closer or further apart.

[0012] Furthermore, the centering slide includes a slide block, a fixed plate, and a rib plate. The fixed plate is disposed on the slide block and is arranged perpendicular to the slide block. The rib plate is disposed between the fixed plate and the slide block, thereby improving the structural strength of the centering slide block.

[0013] The second centering slide and the first centering slide have the same structure.

[0014] Furthermore, both the first and second centering slides are provided with positioning grooves. The positioning grooves include an integrally formed circular segment and a rectangular segment. The rectangular segments are symmetrically arranged on both sides of the circular segment. Screw holes are provided in both the circular and rectangular segments. The number of screw holes in the rectangular segment is multiple and arranged in a straight line, which facilitates the adjustment of the height position of the positioning claw within the rectangular segment.

[0015] Furthermore, the circular segment of the positioning groove is internally threaded with the positioning clamping pin, which is a cone.

[0016] The positioning slot has a positioning claw bolted to each of the two rectangular segments, or each rectangular segment of the positioning slot has a positioning claw bolted to it.

[0017] Furthermore, the positioning claw is a long strip-shaped block, with both ends of the positioning claw bent upwards at an acute angle to form positioning claw one, one end of the positioning claw bent upwards at an acute angle to form positioning claw two, one end of the positioning claw bent upwards at a right angle to form positioning claw three, and one end of the positioning claw bent upwards at an acute angle and the other end bent upwards at a right angle to form positioning claw four.

[0018] The beneficial effects of this utility model through the above technical solution are:

[0019] This utility model features a reasonable structural design. While the headbox positioner is fixed in position, the tailbox positioner is movable, and the distance between them can be flexibly adjusted to accommodate booms of different lengths. The headbox positioner is equipped with a bidirectional lead screw module, which drives two centering slides to move closer or further apart simultaneously. Positioning clamping pins are installed on the centering slides to clamp the boom with holes at the end, thus securing the end of the boom.

[0020] This utility model's tail box positioner is equipped with a lifting module. The lifting module moves the centering slide plate two up and down to accommodate booms with inconsistent center heights at both ends. The lifting module includes a bidirectional lead screw module two, which controls the two centering slide plates two to move closer or further apart simultaneously. Positioning claws are installed on the centering slide plates two. These positioning claws come in various types, shapes, and sizes, facilitating the clamping of the other end of the boom. By combining different types of positioning claws, booms with different cross-sectional shapes can be clamped.

[0021] This utility model has a lifting bracket arranged between the head box positioner and the tail box positioner, which can drive the boom to move up and down, thereby installing the boom between the head box positioner and the tail box positioner, or removing the boom from between the head box positioner and the tail box positioner.

[0029] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0030] like Figures 1-6 As shown, a highly compatible boom welding fixture includes a base 1 with long slide rails, a head box positioner 2, a tail box positioner 3, and a lifting bracket 4. The base 1 is the foundation of the entire welding fixture. The base 1 has a certain length, and long slide rails are installed on both sides of the base 1. Long slide rails refer to slide rails with a certain length.

[0031] A headbox positioner 2 is fixedly mounted at one end of the base 1, and its position remains unchanged. Two centering slides 5 are slidably mounted on the headbox positioner 2. These two slides 5 can slide simultaneously towards each other or simultaneously away from each other, allowing them to move closer or further apart simultaneously. Figure 2 As shown.

[0032] The centering slide 5 includes a slide block 51, a fixing plate 52, and ribs 53. The fixing plate 52 is mounted on the slide block 51, and is arranged perpendicular to the slide block 51, so that the cross-section of the slide block 51 and the fixing plate 52, when connected and combined, forms a "T" shape. Two ribs 53 are provided between the fixing plate 52 and the slide block 51 to improve the installation strength of the fixing plate 52. A clamp is detachably mounted on each centering slide 5, used to cooperate with and fix the boom.

[0033] To drive the centering slide 5, a bidirectional lead screw module 6 is installed on the headbox positioner 2. The bidirectional lead screw module 6 is horizontally arranged, with the two ends of the lead screw rotating in opposite directions. Centering slides 5 are located on both sides of the bidirectional lead screw module 6. The operation of the bidirectional lead screw module 6 can simultaneously move the two centering slides 5 closer together or further apart. The headbox positioner 2 can then drive the bidirectional lead screw module 6 and the centering slides 5 to move together.

[0034] A tail box positioner 3 is slidably mounted at the other end of the base 1. Both the head box positioner 2 and the tail box positioner 3 are rotary positioners. The position of the tail box positioner 3 is adjustable. Specifically, the linear sliding method of the tail box positioner 3 is existing technology, which can use a gear and rack transmission structure to achieve the sliding of the tail box positioner 3 on the base 1, which will not be elaborated here. In this way, the distance between the head box positioner 2 and the tail box positioner 3 can be adjusted to accommodate booms of different lengths.

[0035] The tailgate positioner 3 is equipped with a lifting module 7, which has a lifting function. Here, the lifting module 7 is arranged vertically and has a lead screw module structure. Figure 3 As shown, two centering slides 8 are slidably mounted on the lifting module 7. The two centering slides 8 are arranged horizontally from left to right, and the lifting module 7 can drive the centering slides 8 to move up and down. The centering slides 8 and the centering slide 5 have the same structure.

[0036] The two centering slides 28 can also move simultaneously in opposite directions or in opposite directions. Specifically, a bidirectional lead screw module 29 for driving the centering slides 28 is provided on the lifting module 7. The bidirectional lead screw module 29 is horizontally arranged and has the same structure as the bidirectional lead screw module 6. Centering slides 28 are provided on both sides of the bidirectional lead screw module 29.

[0037] The lifting module 7 drives the bidirectional lead screw module 2 9 and the centering slide 2 8 to move up and down together, adapting to booms with inconsistent center heights at both ends. The operation of the bidirectional lead screw module 2 9 can simultaneously move the two centering slides 2 8 closer or further apart. The tail box positioner 3 can drive the lifting module 7, the bidirectional lead screw module 2 9, and the centering slide 2 8 to move together.

[0038] Both centering slides 28 are detachably equipped with clamps. The clamps on centering slides 1 and 28 work together to clamp the boom. The clamps are either positioning clamping pins 10 or positioning claws 11, thus the clamps are of different types. In this embodiment, a positioning clamping pin 10 is installed on centering slide 15 of head box positioner 2, which can match the end of the boom with the pin hole. A positioning claw 11 is installed on centering slide 28 of tail box positioner 3, which can match the other end of the boom with a different cross-sectional shape.

[0039] During installation, positioning grooves 12 are provided on both the first centering slide 5 and the second centering slide 8, that is, positioning grooves 12 are provided on the fixed plate 52. Figure 4As shown. The positioning groove 12 includes an integrally formed circular segment 121 and a rectangular segment 122. The rectangular segments 122 are symmetrically arranged on both sides of the circular segment 121. The diameter of the circular segment 121 is larger than the width of the rectangular segment 122. Both the circular segment 121 and the rectangular segment 122 are provided with screw holes 13. The circular segment 121 has one screw hole 13 at its center. The rectangular segment 122 has multiple screw holes 13 arranged in a straight line, and the screw holes 13 in the rectangular segment 122 extend into the circular segment 121.

[0040] When the fixture is a positioning clamping pin 10, the positioning clamping pin 10 is a cone. During installation, the positioning clamping pin 10 is internally threaded onto the circular segment 121 of the positioning groove 12. The positioning clamping pins 10 on the two centering slides 5 are arranged opposite each other.

[0041] When the clamp is a positioning claw 11, the positioning claw 11 is a long strip-shaped block. During installation, the positioning claw 11 is bolted to one of the two rectangular segments 122 of the positioning groove 12, or one of the positioning claws 11 is bolted to each rectangular segment 122 of the positioning groove 12. That is, one positioning claw 11 or two positioning claws 11 can be installed on each centering slide plate 2 8, depending on the shape of the boom.

[0042] Note: Due to the different shapes of the boom end faces, the positioning claw 11 has various designs to better adapt to the boom. Specifically, the two ends of the positioning claw 11 are bent upwards at acute angles to form positioning claw 111. The two ends of positioning claw 111 are symmetrical, as shown below. Figure 5 As shown in Figure a. Positioning claw 111 is bent upwards at an acute angle at one end and upwards at a right angle at the other end, forming positioning claw 114, as shown. Figure 5 As shown in Figure b, the first positioning claw 111 bends upward at an acute angle to form the second positioning claw 112, as shown in Figure b. Figure 5 As shown in Figure c. Positioning claw 111 is bent upwards at a right angle to form positioning claw 313, as shown in Figure c. Figure 5 As shown in d. The above are just the shape changes of positioning claw 11. Based on this, positioning claw four 114 also has different height designs, and positioning claw three 113 also has different height designs.

[0043] Therefore, positioning claw 111 and positioning claw 414 are respectively installed on the two centering slides 28. The positioning claw 111 and positioning claw 414 can be used to clamp a boom with an irregular end face shape, such as Figure 6 As shown in Figure a, positioning claws 112 and 113 are installed on the upper and lower parts of one centering slide 2 8, respectively. The same applies to the other centering slide 2 8. By cooperating with the two positioning claws 112 and 113, a boom with a rectangular or trapezoidal end face shape can be clamped, such as... Figure 6As shown in Figure b. Based on the upright installation of positioning claw 3 113, positioning claw 3 113 can also be installed upside down. Therefore, by cooperating with the two positioning claws 2 112 and the two upside-down positioning claws 3 113, it is also possible to clamp a boom with a rectangular or trapezoidal end face shape, such as... Figure 6 As shown in Figure c, the vertical spacing between positioning claws 112 and 113 is adjustable to accommodate booms with workpieces of different sizes.

[0044] To install the boom between the headbox positioner 2 and the tailbox positioner 3, a lifting bracket 4 for supporting the boom is slidably mounted on the base 1 between the headbox positioner 2 and the tailbox positioner 3. There are two lifting brackets 4, which can lift the boom upwards. The lifting brackets 4 are scissor lifts, and they can move on the base 1 in the same way as the tailbox positioner 3, which will not be described in detail here.

[0045] The principle of this utility model is as follows: Select a suitable positioning claw 11 and install it on the centering slide plate 2 8. Move the lifting bracket 4 and the tail box positioner 3 to a suitable position, and then hoist the boom onto the lifting bracket 4. The two lifting brackets 4 rise synchronously, lifting the boom to a suitable height. The two lifting brackets 4 move synchronously toward the head box positioner 2, aligning the pin hole at the end of the boom with the positioning clamping pin 10. The bidirectional screw module 6 drives the two positioning clamping pins 10 to insert into the pin hole, realizing the pre-clamping of one end of the boom.

[0046] The tail box positioner 3 moves towards the head box positioner 2, fitting the mating positioning claws 11 onto the boom end. The bidirectional lead screw module 2 9 drives the positioning claws 11 on the two centering slides 2 8 to pre-clamp. The lifting bracket 4 is lowered by about 5 cm, and then the positioning clamping pin 10 and positioning claws 11 are controlled to clamp the boom again. Then the lifting bracket 4 is lowered to the lowest point, at which point the clamping of the boom is completed.

[0047] After clamping, welding begins. Once welding is complete, the lifting bracket 4 is raised, and then the positioning clamping pin 10 and positioning claw 11 are released, allowing the boom to rest on the lifting bracket 4. Then, the tail box positioner 3 is moved a certain distance away from the head box positioner 2, and then both lifting brackets 4 are moved a certain distance away from the head box positioner 2 simultaneously. Finally, the welded boom is lifted off the lifting bracket 4.

[0048] To optimize the product structure and limit the boom's movement on the lifting bracket 4, a bidirectional lead screw module three (not shown in the figure) is installed on each lifting bracket 4. Clamping arms 14 are located at both ends of the bidirectional lead screw module three, extending upwards from the upper surface of the lifting bracket 4. To prevent the lifting bracket 4 from interfering with the movement of the clamping arms 14, a long guide groove 15 is provided on the upper surface of the lifting bracket 4. The clamping arms 14 pass upwards through the guide groove 15 and extend out of the lifting bracket 4. The bidirectional lead screw module three can drive the two clamping arms 14 to move away from or towards each other, using the two clamping arms 14 that move closer together to clamp the boom.

[0049] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
