Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture with an adaptive flexible clamping unit. Background Technology

[0002] Welding fixtures are key process equipment used in welding production to fix and position workpieces, ensuring welding accuracy and quality. They constrain the position of workpieces through mechanical structures, effectively control welding deformation, and improve production efficiency and safety.

[0003] Traditional fixtures are mostly fixed structures, with extremely limited ranges in the shapes and sizes they can hold. When dealing with workpieces of different shapes and sizes, multiple specialized fixtures are often required, which not only increases equipment purchase costs but also occupies a significant amount of valuable production space. For example, when handling workpieces of various shapes such as round, square, and irregular, traditional fixtures struggle to simultaneously meet clamping requirements, leading to frequent fixture changes during production and significantly reducing efficiency. In terms of adjustment flexibility, traditional welding fixtures offer cumbersome and limited adjustment methods. Many traditional fixtures can only achieve movement in a single direction or adjustment at a fixed angle, failing to meet the needs of complex welding positions and angles. When multi-angle welding is required, operators must readjust the workpiece position or change fixtures, which not only increases operational difficulty and time costs but also easily leads to inaccurate workpiece positioning due to repeated clamping, thus affecting welding quality. Utility Model Content

[0004] The purpose of this invention is to provide a welding fixture with an adaptive flexible clamping unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture with an adaptive flexible clamping unit, including a slide rail, on which two symmetrically mounted clamping components are installed, and further comprising: A mounting assembly installed at the bottom of the slide rail, wherein a vertical rod is mounted at the bottom of the mounting assembly, and an adjustment assembly for adjusting the direction of the slide rail is mounted on the mounting assembly; A fixing base is installed at the bottom of the upright. The upright is rotatably mounted on the fixing base via a rotating shaft. The fixing base has several through holes, and fixing bolts that pass through the through holes are inserted into the upright.

[0006] Preferably, the clamping assembly includes a mounting shell slidably mounted on the top of the slide rail, and a plurality of movable rods are slidably mounted inside the mounting shell, with a spring fixedly mounted between the end of each movable rod and the inner wall of the mounting shell.

[0007] Preferably, the mounting assembly includes a mounting base fixedly mounted on the bottom of the slide rail, a connecting sleeve fixedly mounted on the mounting base, a connecting shaft fixedly mounted on the upright, and the connecting sleeve sliding on the outside of the connecting shaft.

[0008] Preferably, the adjusting assembly includes a fixed rod fixedly installed on the upright, a second spring sleeved on the outer side of the fixed rod, a limiting toothed ring slidably installed on the outer side of the fixed rod, a limiting groove adapted to the limiting toothed ring on the mounting base, and a retaining cover snapped onto the outer side of the fixed rod.

[0009] Preferably, the diameter of the card cover is smaller than that of the limiting toothed ring.

[0010] Preferably, a limiting strip is fixedly installed on the outer side of the fixing rod, and a sliding groove is provided on the limiting toothed ring for sliding on the outer side of the limiting strip.

[0011] Preferably, a connecting seat is fixedly installed on the slide rail by bolts, and a screw is threaded onto the connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The movable rod and spring in this clamping assembly form an adaptive flexible clamping structure. When the workpiece is placed between the two mounting shells, the movable rod retracts into the mounting shell under pressure, automatically conforming to the surface of workpieces of different shapes. Whether it is a regular square, round, or irregularly shaped workpiece, it can achieve precise clamping. Simultaneously, the two clamping components slide on a slide rail, allowing for flexible position adjustment according to the workpiece size, greatly expanding the application range of the tooling. The slide rail rotates on the connecting shaft of the upright via the connecting sleeve of the mounting component, allowing for adjustment of the angle between the slide rail and the upright; the upright is mounted on a fixed base via a rotating shaft, further allowing for adjustment of the angle between the upright and the fixed base. This dual angle adjustment mechanism enables the workpiece to be flexibly positioned in three-dimensional space, meeting the needs of different welding positions and angles, and providing greater flexibility for the welding process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a welding fixture with an adaptive flexible clamping unit includes a slide rail 1, on which two symmetrically mounted clamping components 2 are installed. It also includes: a mounting component 3 mounted at the bottom of the slide rail 1, with a vertical rod 5 mounted at the bottom of the mounting component 3, and an adjusting component 4 mounted on the mounting component 3 to adjust the direction of the slide rail 1; a fixed seat 6 mounted at the bottom of the vertical rod 5, with the vertical rod 5 rotatably mounted on the fixed seat 6 via a rotating shaft, and the fixed seat 6 having several through holes 7, with fixing bolts 8 inserted through the through holes 7 on the vertical rod 5; the two clamping components 2 slide on the slide rail 1, and their positions can be adjusted according to the size of the workpiece to limit the clamping of the workpiece; the slide rail 1 is mounted on the vertical rod 5 via the mounting component 3; the positions of the adjusting component 4 and the slide rail 1 on the vertical rod 5 can be adjusted via the adjusting component 4; the lower part of the vertical rod 5 is rotatably mounted on the fixed seat 6 via a rotating shaft, and fixing bolts 8 are inserted into the vertical rod 5.

[0017] When welding a workpiece, first place the workpiece between the two clamping components 2, then adjust the position of the clamping components 2 to clamp and fix the workpiece on the slide rail 1. Then, adjust the angle between the slide rail 1 and the upright 5, and between the upright 5 and the fixed seat 6 according to the welding requirements. Then, use the adjusting component 4 to limit the slide rail 1 on the upright 5. Insert the fixing bolt 8 through the through hole 7 on the fixed seat 6 into the upright 5 to fix the upright 5 on the fixed seat 6. This adjusts the workpiece at the top of the slide rail 1 to a suitable angle, which is more convenient for subsequent welding processing.

[0018] Based on the above implementation scheme, the clamping assembly 2 includes a mounting shell 21 slidably mounted on the top of the slide rail 1. Several movable rods 22 are slidably mounted inside the mounting shell 21, and a spring 23 is fixedly mounted between the end of each movable rod 22 and the inner wall of the mounting shell 21. Based on the above implementation scheme, a connecting seat 9 is fixedly mounted on the slide rail 1 by bolts, and a screw 10 is threaded onto the connecting seat 9. The mounting shell 21 has through slots the same number as the movable rods 22 inside, and the movable rods 22 slide in the through slots. The bottom of the mounting shell 21 is as follows: Figure 2 The welding of the limit seat is shown, and the mounting shell 21 slides on the slide rail 1 through the limit seat.

[0019] like Figure 1 The mounting shell 21 on the left is fixedly mounted on the slide rail 1 by bolts. The mounting shell 21 on the right is rotatably connected to the end of the screw 10. When clamping the workpiece, the workpiece is placed on the side close to the left mounting shell 21. Then the right mounting shell 21 is moved to the left so that the workpiece contacts the moving rod 22 between the two mounting shells 21. The moving rod 22 is subjected to pressure and retracts into the mounting shell 21, which can automatically adapt to workpieces of different shapes. The right mounting shell 21 can be fixed by the screw 10, so that the workpiece is clamped and fixed on the slide rail 1. When the workpiece is removed, the spring 23 causes the moving rod 22 to automatically return to its original position.

[0020] Based on the above implementation plan, and referring to Figure 3 and Figure 4 The mounting assembly 3 includes a mounting base 31 fixedly mounted on the bottom of the slide rail 1, a connecting sleeve 32 fixedly mounted on the mounting base 31, and a connecting shaft 33 fixedly mounted on the upright 5. The connecting sleeve 32 slides on the outside of the connecting shaft 33. A connecting sleeve 32 is fixedly mounted on the right side of the mounting base 31, and a connecting shaft 33 is fixedly mounted on the right side of the upright 5. The connecting sleeve 32 rotates on the outside of the connecting shaft 33.

[0021] The slide rail 1 rotates outside the connecting shaft 33 via the connecting sleeve 32, and the angle between it and the upright 5 changes, thus adjusting the slide rail 1 and the upright 5 to a suitable angle.

[0022] Based on the above implementation plan, and referring to Figure 3 , Figure 4 and Figure 5 The adjusting assembly 4 includes a fixed rod 41 fixedly installed on the upright 5. A spring 42 is sleeved on the outside of the fixed rod 41. A limiting toothed ring 43 is slidably installed on the outside of the fixed rod 41. A limiting groove 44 adapted to the limiting toothed ring 43 is opened on the mounting base 31. A retaining cover 45 is snapped onto the outside of the fixed rod 41. The diameter of the retaining cover 45 is smaller than that of the limiting toothed ring 43. The retaining cover 45 is detachably installed on the outside of the fixed rod 41 and can be removed.

[0023] When it is necessary to rotate the mounting base 31, install the retaining cover 45 onto the left end of the fixing rod 41, and then push it into the mounting base 31 so that the limiting toothed ring 43 disengages from the limiting groove 44. At this time, the mounting base 31 loses its limit and can rotate freely on the connecting shaft 33. After the mounting base 31 is adjusted to a suitable position, remove the retaining cover 45. The second spring 42 loses pressure and automatically rebounds, moving the limiting toothed ring 43 into the limiting groove 44 to limit the mounting base 31 onto the fixing rod 41, thereby limiting the slide rail 1 onto the upright rod 5.

[0024] Based on the above implementation scheme, a limiting strip 11 is fixedly installed on the outer side of the fixing rod 41, and a sliding groove is provided on the limiting toothed ring 43 to slide on the outer side of the limiting strip 11.

[0025] The limiting toothed ring 43 slides on the limiting bar 11 through the sliding grooves on both sides, so that the limiting toothed ring 43 moves axially on the fixed rod 41.
